Improvements in Apparatus for Punching or Perforating Whalebone
and other Semi-hard Substances.
I GUSTAVE ROSENWALD of the firm Rosenwald Brothers, 27 Noble Street,
City of London, Manufacturers do hereby declare the nature of this invention to
be as follows: :-
This invention has for object constructing or arranging a grip and punch or
perforator combined in a case for independent or consecutive action such as first
gripping the article and then for indenting or for making a hole clean through the
material.
The invention is specially intended for piercing the ends of strips of whalebone and
their substitutes where a sewing or stitching is required when such strips are used for
ladies corsets, said material being very easily cracked, split or opened out in the
grain at the hole by an awl or other appliance employed except when the hole is
drilled, which is a somewhat tedious operation especially where several holes close
together are required.
By my invention I can indent or pierce holes very close together with rapidity
and ease without risk of cracking, splitting or otherwise disfiguring the strip.
The invention consists of a plunger returnable by a spring after action on a hand
lever for holding the strip placed between it and a base, and of a blunt needle
within the plunger, also returnable by the spring during the return of the lever by
the plunger spring in order to leave the space or gap between the base and the
plunger open for the insertion of the strips or pieces in succession.
The lever has two bearing surfaces one for acting on the plunger and the other
for forcing in the piercer by a continued pressure on the lever, which may be of
any desired shape for gripping by the hand as with a pair of pincers or by some
other form.
For a band appliance I make the barrel on which the plunger and needle work
as a continuation of one handle and form the base from a kinked or bent end of it
into which I arrange a hollow screw for adjustment to suit the thickness of the
material to be operated upon, the hollow in the screw being for the punched out
pieces to escape.

Improvements in Apparatus for Punching or Perforating Whalebone
and other Semi-hard Substances.
I, GUSTAVE ROSENWALD, of the firm Rosenwald Brothers, 27 Noble Street,
City of London, Manufacturers, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention has for object constructing or arranging a grip and punch or
perforator combined in a framing for independent, or consecutive action, such as
first gripping the article, and then for indenting, or for making a hole clean through
the material.

page_text: The invention is specially intended for piercing the ends of strips of whalebone,
and their substitutes where a sewing or stitching is required when such strips
are used for ladies corsets, said material being very easily cracked, split, or
opened out in the grain at the hole by an awl, or other appliance employed, except
when the hole is drilled, which is a somewhat tedious operation, especially where
several holes close together are required.
•
By my invention, I can pierce holes very close together with rapidity and ease,
without risk of cracking, splitting, or otherwise disfiguring the strip.
In my invention, I employ a plunger, or grip returnable by a spring after an
action on a hand lever for holding the strip placed between it and a leg forwardly
bent from the other handle, and of a blunt needle within the plunger, also
returnable by the spring during the return of the lever by the plunger spring in
order to leave the space or gap between the leg and the head open for the insertion
of the strips or pieces in succession. The leg has a hollow screw for adjustment to
suit the thickness of the material to be operated upon, the hollow in the screw
being for the punched out pieces to escape.
The annexed drawings show my invention.
Figure 1 is a part sectional side elevation.
Figure 2 a front elevation.
Figure 3 detail views of the internal appliances.
A, B, are two lever handles pivoted together at C, one of said levers being
furnished with a plate spring D for pressure against the other for keeping them
apart, except when forced towards each other during a punching operation.
The lever A has a barrel E, within which a grip tube F and a punch G have
motion from the action of links H and cheek I of the lever B which links connect
them to the hand lever B when moved in one direction by the hand, and in the
reverse direction by a helical spring J which encircles the stem K of the punch G,
said helical spring abutting against a shoulder L of the punch G, and the base M
of the grip Frespectively, which latter is slotted at N for a cross pin P of the
punch stem K to ride along freely for the length of the slot only.
Q is a rearwardly and forwardly bent leg from the barrel E, and is provided
with an adjustable screw R to allow for a thick or a thin substance to be placed in
between the head S of the barrel and of the leg Q. The adjustable screw R is
hollow, and receives the pieces of substance in succession.
The action is as follows;-A strip of any substance is first placed between the
head S and leg Q, the lever B is pressed towards the lever A, and the cheek I
throws forward the links H, the spring D being simultaneously compressed..
The motion of the links H causes the punch G, the grip F, and the spring J to
rise until both punch and grip touch the substance on the head S, and force it into
contact with the screw R, a further motion of the lever B now forces the punch G to
a greater distance, the pressure exerted overcoming the tension of the springs by
reason of the pin P riding in the slot N, so that the punch passes into the
substance, and niakes a hole therein, while the part of the substance surrounding
the punch is being held firmly by the grip F. The end of the punch in passing
through the substance pushes the piece so punched out into the hollow of the
screw.
The pressure on the lever B is now released, and the springs D and J return the
parts to their normal condition to free the substance for its ready removal, and
the placing in of another piece for a similar operation.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is:
: -
1. In a hand punch, the several parts hereinbefore described and arranged in the
manner shown in the annexed drawings for operation, as set forth.
2. Providing a hand punch having a rearward and forwardly projecting end Q
