of one-third to Martin J. Dittman and one
third to Harry E. Sills, both of Youngstown,
Application November 2, 1936, Serial No. 108,843
1 Claim.
My invention relates generally to means for
perforating can tops to provide pouring and air
holes therein, and particularly to a can punch
of this character which can be left in the holes
CF. made by it to act as a twin stopper, and an im
portant object of the invention is to provide a
simple and practical arrangement of this char
Another important object of my invention is to
ment with the plate 6. This pivot l0 permits
the plates to ‘be pivoted to the relationships
shown in Figure l or to the relationships shown
in Figure 4 whereby to bring the perforating pins
8 and 9 to the greatest distance apart or to the
closest spaced positions, in accordance with the
requirements, and the size of the can top.
‘The device of the invention is adapted to be
extended on the can top l2 until its terminals
are near diametrically opposite parts of the ridge
provide a can punch of the character indicated
which is adapted to make two holes in one opera
or bead l3 which is usually on the can top, so that
tion, which punch is adapted to be adjusted to
the points 8 and 9 will be properly positioned for
driving through the can top to provide pouring
?t can tops of dilferent diameters and sizes.
Other important objects of my invention will be
15 apparent from a reading of the following descrip
tion taken in connection with the drawing,
wherein for purposes of illustration I have shown
a preferred embodiment of my invention.
In the drawing:—
20 ‘Figure 1 is a general top plan view of the em
Figure 2 is a transverse vertical sectional view
taken longitudinally through the embodiment
and through the upper part of a can showing ap
25 plication of the invention for perforating the top
of the can and acting as twin stoppers for the
holes made in the top of the can.
Figure 3 is a transverse vertical sectional view
taken through Figure 1.
(Cl. 220-»51)
Figure 4 is a view similar to Figure 1 but show
ing the plates re-arranged for making close to
gether perforations in the can top.
Referring in detail to the drawing, the numeral
5 generally designates the device of the inven
35 tion which is composed of a lower T-hole shaped
plate 6 and an upper T-hole shaped plate 1.
Fastened in the approximate center of the three
quarter circular portion of each plate is a corre
sponding perforating pin 8, 9 and from the elon
40 gated portion of the lower plate 6 and near the
free end of its elongated portion rises a double
headed rivet or other suitable pivot II] which
works in an elongated slot ll formed in the elon
gated portion of the upper plate 1, the head on
45 the pivot holding the plate ‘I in sliding engage
and air holes therein. Pressure upon the top of
the device so positioned will force the points 8 15
and 9 into the positions shown in Figure 2. In
the event that the plates 6 and 'l have relatively
angulated positions after driving of the points
through the can top, these plates may be moved
into alignment, with the curved and enlarged 20
ends of the plates rollingalong the inner surface
of the can bead during this action, so that the
device as a whole adapts a neat and convenient
position for handling as a double stopper.
Although I have shown and described herein ‘
a preferred embodiment of my invention, it is
to be de?nitely understood that I do not desire
to limit the application of the invention thereto,
and any change or changes may be made in the
materials, and in the structure and arrangement 30
of the parts, within the spirit of the invention
and the scope of the subjoined claim.
What is claimed is:—
A combined can top punch and seal compris
ing a pair of elongated slidably and rotatably -
superposed plates having respective can top pierc
ing and sealing pins projecting from the under
side thereof, one of said plates being formed with
a longitudinal slot, a pin fastened rigidly to the
remaining plate and projecting through said 40
slot, and a head on said pin bearing against the
outer side of the slot-equipped plate to retain the
plates assembled.
