PAPER PUNCH.
No. 450,224. Patented Apr. 14,1891.
UNITED STATES PATENT OFFICE.
ALBERT l3. DICK, OF CHICAGO, ILLINOIS.
PAPER-PUNCH.
SPECIFICATION forming part of Letters Patent No. 450,224, dated April 14, 1891.
Application filed June 1'7 1890. Serial No. 355,709. (No model.)
To all whom it may concern.-
Be it known that I, ALBERT B. DICK, a citizen of the United States, residing at Chicago,
' in the county of Cook and State of Illinois,
have invented anew and usefullmprovement in Paper-Punches, of which the following is a specification.
The object of the invention is an eifective paper-punch of economical construction.
In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of the blank which forms the body of the punch, showing the same after it has been stamped and before bending. Fig. 2 is a side elevation of the same after bending with the punches in place, and Fig. 3 is a front elevation of the same.
The blank or of the punch is formed from spring metal by stamping from a fiat plate at a single operation and subsequently bending.
I) b are holes which receive the screws or other attaching devices which secure the punch, when desired, to a suitable base.
0 c are holes of larger diameter than the holes b b, stamped out in such position that when the plate a is bent, as shown in Fig. 2, the holes 0 will be directly above the holes I) and will permit a screw-driver to be operated to force the screws home in the holes b 1), whereby the punch is secured to its base.
d d are holes through which the male punches e 6, carried by bar f, project.
9 is ahole through which a screw is adapted to pass to secure both the handle hand punchcarrying bar f in place. The right-angular cut 11 i at each side of the plate a is made for the purpose of permitting the partially-severed portion j to be bent, as shown in Figs. 2 and 3, to form both the paper-guide and female member of the punch.
k k are holes cutout of the severed portion j, and Z Zare holes cutout of the blank a, which, when the portion j isbent, as shown in'Fig. 2, are directly opposite the holes, and form, together with the holes is, the female member of the punch. The bending of the blank a to form the upper plate of the punch takes place ing taking place about on the dotted line 00 0c of Fig. 1 and being a very gradual one as shown in Fig. 2. By locating the bend rear- Wardly of the attaching-point the durability of the punch is increased, as there seems to be no tendency of the spring metal to crack on the line of its bending.
The male members ofthe punch care formed with a V-shaped cut, so that an advanced cutting portion will be presented on the downward motion of the punch, the action of which will be to effect a gradual cutting of the paper on two sides rather than a positive stamping out of the paper or a cutting on one side only.
It will be seen that a punch constructed as above described is economical of manufacture and efficient in operation.
What I claim is- In a paper-punch, the combination of a spring-metal blank comprising an upper and lower plate in one piece, male-punch members carried by the upper plate, and a paperguide for each punch member, comprising a partially-severed bent strip on the lower plate, said bent strips being provided with holes to permit of the passage of the male punches, substantially as set forth.
This specification signed and witnessedthis 14th day of June, 1890. 0
