_Stock:_ Piece of soft steel 1/8 in. thick, 3 × 7 ins., for the
escutcheon. Knocker, 3/4 × 1/4 × 5-1/2 ins. Eye bolt 3/4 × 1/2 bar any
length. Strike pin, 3/8 in. round, 3/4 in. long (on bar).
[Illustration]
_Directions:_ Mark off on a thin sheet of metal the outline of the
drawing. Cut the escutcheon plate same shape as the drawing (using cold
chisel). File it up so that the edges are perfectly smooth. With a
1/8-in. drill, drill holes for the screws.
_Knocker:_ Split the 5-1/2-in. piece of stock, leaving 1 in. square
for the eye bolt and eye untouched. Round up the wings to 1/4 in.
in diameter. Twist the two wings according to the design. Bring the
two loose ends together and weld up 1-1/2 in. from the end. The same
heat will enable you to draw and shape the loop. Spread out the parts
between the weld and the twist, forming in this way the loop. _Eye
bolt:_ This is best made by working the end of a bar any length of the
size stock given. The drawing shows a jaw-shaped holder to receive the
eye of the knocker.
Punch a hole about 3/4 in. from the end of the bar about 1/4 in. in
diameter. Cut out the piece between the hole and the end of the bar
with a chisel. This forms the jaw. The small pin end is fullered down
and drawn out the same as you did on the boss of the ring for the
andiron, then it is riveted on to the escutcheon plate (see drawing)
in place to receive the knocker. A 1/8-in. hole is drilled through
this and through the eye of the knocker for the rivet to fasten the
two together. The strike pin is made in the same way as the eye bolt,
except that there is no jaw, just the plain piece of iron. The sketch
shows a simple projection for the knocker to strike on.
Door knockers were used formerly in place of door bells, but to-day
they are merely used for ornamental purposes.
