Improvements in Perforating Apparatus.
I, WILLIAM OTTERBEIN GOTTWALS, of 377 O'Connor Street, Ottawa, in the
County of Carleton, Province of Ontario, Dominion of Canada, Manufacturer, 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:—
My invention relates to punches or perforators and especially to that class of
these devices ordinarily attached to the base-board of a letter or bill file, and
adapted for the production of holes in a paper in order to facilitate the application
of the latter to the paper holding arches of the file.
One class of such perforators comprises a base plate provided with punches and
a superimposed spring plate having corresponding matrices or holes for co-operation
with the punches, and it is to this class that my present improvement more
particularly relates. Where the matrix is formed in-the bottom plate a receptacle
for the punchings may conveniently be provided below the plate, and such an
arrangement has heretofore been employed. In the other class of perforators,
however, first above described, there is no receptacle for the punchings and as they
are forced through the matrix to the top of the spring plate they fall to the floor
or are otherwise scattered and are productive of untidiness and annoyance. The
said spring plate is provided with actuating means for depressing it ordinarily
situated at or near the middle of the plate, and any means provided for the reception
of the punchings must be adapted to the movement of the spring plate and must
permit the free operation of the plate operating device.
According to my invention I mount upon the spring plate, so as to be movable
therewith, a receptacle or receptacles into which the matrix openings deliver, which
receptacles are otherwise closed and adapted to retain the punchings until such
time as they are intentionally opened for the purpose of emptying them into a
waste basket or other receptacle. My invention further consists in the means for
closing and emptying the said receptacles. My invention further consists in the
parts and combinations thereof hereinafter set forth and claimed.
In order to make the invention more clearly understood, I have shown in the
accompanying drawings means for carrying it into practical effect, without
limiting my improvements, in their useful applications, to the particular construction
which, for the sake of illustration, I have delineated. In said drawings:-
Fig. 1 is a perspective view of a perforator embodying my invention.
Fig. 2 is a sectional view of the same on line 11-11, Fig. 3, the device being
here shown on a larger scale.
Fig. 3 is a sectional view, also enlarged, on line III-III, Fig. 2.
Referring to the drawings, 1 indicates a base plate provided with punches 2 and
adapted to be secured, as by screws or rivets through the apertures 3, to a file board
not shown.
4 is a spring plate formed with matrix apertures 5 and secured at one edge,
as by rivets 6, to the base plate 1 or to other suitable fixed support, so that when
it is forced towards the plate 1 the apertures 5 will accurately register with the
punches.

page_text: The actuating means for the spring plate consists preferably of a lever 7
journaled by its ends 8 in bearing brackets 9 fixed on the base plate 1. This
lever is formed just above the spring plate with cam bearings 10, which, upon the
oscillation of the lever to the left in Fig. 2, will bear upon the spring plate 4 and
depress it. The bearing brackets pass to the upper side of the spring,plate through
slots 11.
•
At 12 are indicated the receptacles for the punchings each mounted upon the
movable spring plate 4 in such manner that the matrix 5 opens and will deliver the
punchings into the receptacle. The main body of the receptacle consists preferably
of a metallic box closed at one end as indicated 'at 13, open at the other end,
and united with the spring plate by lugs 14 which pass through apertures or notches
in the plate and are clinched upon the bottom thereof. 15 indicates the door
of the receptacle. It is preferably connected with a longitudinal sliding plate '16
situated beneath the top of the receptacle and connected with it by a pin 17 which
passes through a slot 18 in the top of the box and has a head or washer 19 engaging.
the top surface of the latter. A connection between the slide and the receptacle
is not, however; necessary, as the former may be held in place by friction. 20 is a
downward extension formed at the inner end of the slide, and engaging the plate 4.-
When the door' 15 is moved outward the extension 20 serves to gather the punchings,
in the receptacle and draw them out to its open end, thus preventing any sticking.
or packing of the punchings" in the receptacle, or any difficulty in emptying the
latter. Formed with the door 15 is an upward extension 21 which serves as a
thumb piece whereby the sliding door may be withdrawn.t
The slide 16 is, by preference, of spring metal slightly bent as indicated in Fig. 2,
so that it will press upward at its outer end against the top of the receptacle and
thus tend to retain its position when closed; and also will throw the door 15.
somewhat upward as the latter is withdrawn so as to carry the lower edge. of
the door clear of the fixed edge of the spring plate, (see the dotted lines in
Fig. 2):
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a perforator for bill files or other purposes the combination with a spring
plate formed with 'matrix openings, of a receptacle for punchings mounted above
said plate, and openings, substantially as set forth..
2. In a perforator the combination of a base plate provided with punches; a
spring plate formed with matrix openings adapted to register with said punches
and situated above the latter, and receptacles for punchings mounted upon the
upper or outer side of the spring plate over said openings and movable with the
plate, substantially as set forth
3. In a perforator the combination with a spring plate formed with a matrix
opening, of a receptacle mounted upon said plate over the opening, a slide within
the receptacle, a downward extension 20 at the inner end of the slide, and a door
carried at the outer end of the slide, substantially as set forth."
4. In a perforator the combination with the spring plate 4 having a matrix
opening 5, of a receptacle mounted upon and carried by the said spring plate at
the outer side of the opening and formed with a slot 18, a slide within the receptacle
provided with a door; and a pin connecting the slide with said slot, substantially as
set forth.'
5. In a perforator the combination with the spring plate 4 having: a matrix
opening, of a receptacle mounted on the outer side of the plate above the opening,
a bent spring slide 16 within the receptacle, and a door carried by the slide, as set
forth.
6. The combination with the spring plate of the perforator, of the receptacle pro-
vided with a slide the inner end of which is bent downward to form the extension 20

page_text: and the outer end of which is bent downward to form a door and upward to form a
means for withdrawing the slide, substantially as set forth.
Dated this 13th day of June 1895.
