possess but one useful quality, that of seizing objects like pincers.
In nearly every act performed by the natural fingers are combined
flexion, extension, prehension, and many other different movements; this
combination no mechanic has ever been able—and probably none ever will be
able—to successfully reproduce in an artificial hand. It is, therefore,
practically useless that the fingers should be movable, since a less
complicated, lighter and stronger hand can be made with fingers rigid,
in a half-closed, natural position, articulating the thumb only, which
results in a more powerful spring and consequently a greater degree of
firm grasping power. The fingers being strengthened with steel plates
running through them, reinforced with a covering of rawhide, and securely
fastened to the hand, heavy objects may be lifted without danger of the
fingers straightening out and the object dropping to the ground.
While we furnish the hand with movable fingers, and the rubber hand
with ductile rubber fingers, the wooden hand with rigid fingers and
movable thumb is recommended as giving the most practical, durable, and
satisfactory service.
_The Color_
Artificial hands are covered with a delicately tinted enamel, as nearly a
flesh color as it is possible to make; but in order that they may be less
conspicuous and the illusion more complete a glove should be worn at all
times. We furnish a pair of gloves with each hand.
_Tools and Implements_
Tools and implements in almost limitless variety can be used in an arm
in place of the hand. Those most frequently used are the plain hook,
double hook, ring, knife, fork, brush, and spoon. People who have never
worn arms hardly know what will be of service to them. Special tools
are required for special work, and these can be subsequently provided
when it has been determined what will be most useful. With all arms with
detachable hands, or rubber hands with the palm socket, we furnish a
plain hook, knife, fork, and brush, without extra charge, or the price
of any of these implements that are not wanted will be deducted from the
price of the arm.
_Finger Construction_
Usually the fingers for artificial hands are made of a single piece
of wood, and it is obvious if the finger is curved or flexed that at
some point the grain of the wood will be directly across the finger and
will quickly break if subjected to any considerable strain. To obviate
this difficulty we make the fingers for the wooden hands of two pieces
of wood; on one side the grain or fibre runs lengthwise, and on the
other crosswise, and between these two pieces of wood is placed a steel
plate, and all are firmly riveted together, the steel plate projecting
sufficiently to be securely riveted to the hand. The fingers are next
entirely covered with rawhide, which, together with the other precautions
taken against breakage, make them sufficiently strong to support the
weight of the wearer. See No. 300, page 64.
_Partial Amputation of Hand_
No. 301 (page 64) represents a stump after partial amputation of the
hand, leaving free use of thumb, but it is with difficulty that this
can be brought in contact with the remaining stump so as to be of
service. No. 302 represents, for stumps of this description, a wooden
sheath, terminating in immovable fingers partially closed, the hand
being attached to the wrist and forearm by means of a leather lacing
attachment. The sheath is covered with rawhide and enameled, and the
fingers made as shown in No. 300. Price $40.
Should there be amputation at the base of two or three fingers only,
with no impairment in the movements of the remaining one or two, so that
they can be brought in firm contact with the thumb, what is left of such
a mutilated hand is far more useful than anything that can possibly be
made to supplement it, but to conceal the loss and give the hand a more
perfect appearance, fingers can be made and applied as represented by No.
302, over which a glove should be worn.
Nos. 303 and 304 (page 64) show an apparatus useful in all kinds of labor
for persons who have undergone a partial amputation of the hand. It
consists of a leather sheath, laced to the forearm. Attached to the under
surface of this sheath is a steel plate, which extends downward under the
stump, turning up slightly at the end. At the end is an aperture through
which it is possible to slip the handles of tools and implements, passing
them beneath the stump, where they are securely held in place by pressure
of the stump. Price $20.
[Illustration: 300 301 302 303 304 305 306 307 308 309 310 311 312 313
314 316 317]
No. 305 represents a stump after an amputation of all the fingers and
thumb, and No. 306 an artificial wooden hand for same, with stationary
fingers and articulated thumb with a powerful spring to be opened with
the assistance of the sound hand. Price $40.
_Rubber Hand_
With the assistance of the other hand, or by pressing against some
resisting body, the ductile rubber fingers of the hand No. 307 may be
changed in position to suit the needs of the wearer as shown by the
dotted lines in the illustration. For those who prefer the rubber to the
wooden hand it will be furnished with any of the arms we make. It can
be attached permanently to the forearm, detachable at the wrist, with
provision for using a hook of other implement in place of the hand, or
furnished with a palm socket and lock for the use of hook, knife, fork,
etc., without removing the hand. See No. 308.
_Connections_
No. 309 represents a new method for connecting the hand and arm.
Heretofore the devices in use could not be absolutely relied upon to keep
the hand or tools in place. It mattered not how strongly the fingers were
made for lifting heavy weights, the customary spring or set-screw used
for locking this connection was liable to loosen or give way without
warning and cause much annoyance, if not injury. On the hand plate two
studs are riveted, the heads of which pass into keyholes in the arm
plate. With a slight turn of the hand the heads pass into the slots of
the keyholes, bringing the heads of the studs under the arm plate; they
are kept immovable with a spring that automatically slips into a slot in
the edge of the plate; the spring is released by a pressure of the thumb
of the sound hand in twisting the artificial hand off. The hook and other
tools have a lug at the end of the spindle or shank; after passing the
shank through the hole in the center of the arm plate, it is turned to
any desired position and held firmly in place with the wing nut, as shown
in No. 310.
[Illustration: 318 319 320 321 322 323 324 325]
_Some of the Implements_
Some of the implements that may be attached in the wrist plate when the
hand is removed are also shown in the illustration. All excepting the
brush are made of steel, or other suitable metal.
No. 310—Single Hook Price $1.00
No. 311—Brush ” 1.00
No. 312—Spoon ” 1.00
No. 313—Table Knife ” 1.00
No. 314—Table Fork ” 1.00
No. 316—Double Hook ” 3.00
No. 317—Ring ” 2.00
Special knife, fork, brush, and hook will be made for use in the palm of
rubber hand, No. 308, without additional charge. Other tools, such as
pincers, claw hook, clevis, etc., will be made to order when desired.
_Wrist Joint Amputations_
These usually leave a stump somewhat larger at the end than immediately
above (see No. 318, page 64), thus providing a means of securely applying
the arm and keeping it in place without the necessity of attachment above
the elbow, as shown in No. 319.
Attachments above the elbow may, however, be put on if thought best, and
for amputation at or a short distance above the wrist it is preferable
to make the connection at the elbow with leather straps, as shown in No.
320, rather than with steel joints.
The socket of any arm for amputation between wrist and elbow will be made
to lace if desired.
PRICES, NOS. 319 AND 320 (See page 66)
With wood or rubber hand, permanently attached to forearm,
no provision for tools, and without attachment above
the elbow $30.00
The same with attachment above the elbow 35.00
Rubber hand, not detachable at wrist, but with palm socket,
including knife, fork, hook, and brush, without attachment
above the elbow 35.00
The same with attachment above the elbow 40.00
With wood or rubber hand, detachable at the wrist, including
knife, fork, hook, and brush, without attachment above
the elbow 40.00
The same with attachment above the elbow 45.00
No. 321 represents arm for amputation below the elbow, leather socket
and leather lacer above the elbow, both reinforced with steel frame,
connected at elbow with steel joint straps.
No. 322 is a detachable wooden hand, with rigid fingers and movable
thumb. A traction rod for opening the thumb with motion of shoulder is
shown in the illustration; a web strap is buttoned to the upper end of
the traction rod and passes over opposite shoulder, as shown in No. 326,
page 70. Any motion of the shoulder that will draw on this rod will open
the thumb, and when the tension is released a strong spring in the thumb
brings it back in contact with the first finger. For single amputations
there is little or no advantage in having this attachment put on; it
necessarily requires more complicated and expensive mechanism, without
any practical gain to the wearer. For double amputations something
of this kind must be depended upon for assistance, and to obtain the
greatest benefit from artificial arms, means similar to this for
operating the movement of the thumb are absolutely required. One or more
movable fingers in conjunction with the thumb may be operated in the same
manner.
PRICES, NO. 321
Including Plain Hook, Knife, Fork, and Brush
Arm without hand, used as a peg arm; a hand may be
subsequently applied $25.00
Arm with wooden or rubber hand, detachable at wrist 50.00
Arm with wooden hand and traction rod for opening thumb from
shoulder 60.00
_Ball-and-Socket Wrist Joint_
No. 323 represents arm with ball-and-socket wrist joint for amputation
below the elbow, but not suitable for an amputation near the wrist for
the reason that the space in that locality is required for the mechanism
of the joint. In the various uses to which an artificial hand may be put,
a change in the position of the hand is often desirable; for example,
in keeping a book or paper in position while being written upon with
the sound hand, the artificial hand can be turned so that the tips of
the fingers will rest upon and hold the article securely in place. In
bringing the arm in front of the body the ball-and-socket joint admits
of the hand being brought near to the body in a very easy, lifelike
manner. In other positions desired the hand may be placed at the degree
of flexion most convenient and helpful and that giving the most natural
appearance. No. 332, on page 72, gives an illustration of the details
of the joint. The forearm and attachment above the elbow are leather,
supported with steel framework same as No. 321. Wooden hand with movable
thumb is furnished with or without traction rod for opening thumb with
shoulder movement, but no provision is made for the use of a hook or
other implement in place of the hand. A rubber hand with palm socket for
implements can be attached if preferred, but is somewhat heavier. For
persons not employed in laborious occupations and who have no occasion
to use a hook or similar implement, this style of arm is desirable; for
others we would recommend No. 321.
PRICES, NO. 323
Without traction rod for opening the thumb $50.00
With traction rod attachment for opening thumb by shoulder
movement 60.00
_For Deformed Arm_
No. 324, page 66, represents irregularly formed forearm and hand, the
forearm being considerably shorter than the opposite one. No. 325
represents artificial arm and hand made to supply the deficiency. The
hand may be wood or rubber and detachable or not at the wrist, and
provision made for the use of implements the same as in case of an
amputation. These malformations are treated mechanically the same as
amputations. Plaster moulds or casts of the deformed parts are required,
together with measurements of the opposite arm and hand.
PRICES, NO. 325
With wood or rubber hand $50.00
With wooden hand, thumb opened by movement of shoulder 60.00
_Manner of Attaching Arm and Straps_
No. 326 illustrates arm for amputation below the elbow, equipped with
shoulder cap, strap passing around body for holding it in place, and the
attachment for opening the thumb by movement of the opposite shoulder. If
thumb is to be opened with the assistance of the sound hand, this extra
strap and traction rod are omitted.
[Illustration: 326]
_Arm for Amputation above the Elbow_
No. 327 on the next page represents a wooden arm for amputation above
the elbow, fitted with cord for raising forearm and locking it at right
angles. This is operated as shown in No. 330, while the mechanism is the
same as shown in detailed drawing No. 332. Wooden or rubber hand No. 328
is furnished permanently attached or detachable, but this arm may be used
as a peg, without hand, hook No. 310 or other implement being used in
place of the hand. It can also be made as a peg without a joint at elbow,
straight or curved to any desired angle.
PRICES, NO. 327
Including Hook, Knife, Fork, and Brush
Without elbow joint or hand $30.00
Without hand, but with elbow joint without gearing for
raising forearm 35.00
Without hand, but with elbow joint with gearing for raising
forearm 40.00
With wooden or rubber hand permanently attached, without the
implements and without gearing for raising forearm 50.00
With gearing for raising forearm 60.00
With detachable wooden or rubber hand, including implements,
without gearing for raising forearm 60.00
With gearing for raising forearm 65.00
_Manner of Attaching_
No. 330 represents the corset that is used with arms for upper
amputation. The arm is laced or buckled to the corset, and draught cord
in the back is for raising the forearm by a shrug of the shoulders.
_Ball-and-Socket Wrist Joint for Amputation above the Elbow_
No. 331 represents wooden arm for amputation above the elbow, with
ball-and-socket wrist joint. An explanation of the ball-and-socket
wrist for amputation below the elbow is given on page 69 under No. 323.
The joint is universal and admits of placing the hand in any position,
as shown by dotted lines. This is kept in place by spring friction on
the ball. The wrist cannot be made quite the natural shape—that we are
able to produce without the ball-and-socket joint; but this must be,
necessarily, round. This part, however, is usually covered with the cuff
or sleeve and is not conspicuous.
[Illustration: 327 328 329 330 331 332 333 334 335]
No. 332 is a sectional view of the arm and hand. A forward impulse of
the shoulder and stump causes traction of the cord, moving the geared
segment wheels so as to raise the forearm to any degree of flexion, when
it is retained in position by means of a latch passing through a spring
post and locking automatically. The wearer is enabled to conveniently
carry a coat, shawl, basket, etc., on the artificial arm. A pressure on
the button underneath the arm releases the lock, and the forearm is again
under control of the stump and shoulders. The spring in the hand is for
keeping the thumb in position and is the same as we put in all hands with
movable thumb.
PRICE, NO. 331
With wood or rubber hand $70.00
_Combination Table Knife and Fork_
No. 333, page 72, represents one of these useful implements, designed and
made expressly for those who have been deprived of the use of one hand,
and no such person can afford to be without one for a day. The blade is
thin steel, ground to a sharp edge and terminating in a fork. A rolling
motion will cut the food, and a twist of the hand will bring the fork
into position for use. No. 334 represents a leather sheath into which the
knife can be inserted.
PRICES, NOS. 333 AND 334
Redwood handle $0.60
Ebony handle .75
Bone handle 1.00
Ivory handle 3.00
Pearl handle 4.00
Sheath, extra .25
_Pocket Knife for One-armed Persons_
No. 335, page 72, represents a simple, serviceable knife that can be
operated quickly and conveniently with one hand. A pull of the thumb
opens the blade slot, the blade drops down and out and is securely
locked; invert the knife, with the blade up, and a pull of the thumb
allows it to drop back into the handle.
PRICES, NO. 335
Five and one-half inches long when opened $0.50
Nine inches long when opened 1.00
