MISCELLANEOUS INVENTIONS.

An improved finger ring has been patented by Mr. David Untermeyer,

of New York city. The object of this invention is to furnish finger

rings so constructed that they can be opened out to represent

serpents, and which, when being worn, will give no indication of

being anything more than rings.

An improved heel skate-fastener has been patented by Mr. Elijah S.

Coon, of Watertown, N.Y. This invention consists, essentially, of a

screw threaded hollow plug or thimble, a dirt plate for covering the

opening in the plug, and a spring for holding the dirt plate in

place. This fastener possesses several advantages over one that is

permanently attached to the heel. Being cylindrical, it is more

easily connected, because the hole for its reception can be made

with a common auger or bit without the necessity for lasting the

boot or shoe or using a knife or chisel. Being screw threaded it can

be readily screwed into place with a common screwdriver; this also

enables it to be screwed either in or out, in order to make it fit

the heel key. The screw thread permits of screwing it in beyond the

surface of the heel, so as to prevent it from wearing out by the

ordinary wearing of the shoe.

An improved velocipede has been patented by Messrs. Charles E.

Tripler and William H. Roff, of New York city. The object of this

invention is to obtain a more advantageous application of the

propelling power than the ordinary cranks, to avoid the noise of

pawls and ratchets, and to guard the velocipedes against being

overturned should one of the rear wheels pass over an obstruction.

Mr. Charles F. Clapp, of Ripon, Wis, has patented a novel

arrangement of a desk attachment for trunks. The desk and tray may

interior gauge, and an adjustable feed pipe extension.

Mr. John H. Conrad, of Charlotte, Mich., has patented a portable

sliding gate which will dispense with hinges and which can be used

An improved reversible pole and shaft for vehicles has been

patented by Mr. Francis M. Heuett, of Jug Tavern, Ga. The object of
