Cl. B26l` I 02 U.S. Cl. 83-468 3 Claims ABSTRACT OF THE DISCLOSURE A paper punching device has a paper edge stop slidably mounted on its base and movable by a lever operable cam to position the edge stop in several predetermined positions. Thus, the spacing between the edge of a paper abutted against the edge stop and the holes punched therein can readily -be adjusted by moving the edge stop.
BACKGROUND OF THE INVENTION This invention relates to paper punching devices of the type comprising a base, paper-locating means on the base, a pivotable operating member and a plurality of punches coupled to the operating member and coacting with holes in the base for punching papers located on the base.
It is an object of the invention to provide a punching device of this type in a convenient form.
SUMMARY OF THE INVENTION A paper punching device in accordance with the invention includes a base, an operating member pivoted to said base, a plurality of punches slidable relative to the base and coupled to the operating member to be driven through holes in the base on actuation thereof, a paper edge stop slidably mounted on the base for movement in a direction perpendicular to a direction in which the punches are spaced, a circular cam disc engaged in a hole in the edge stop for moving the edge stop towards and away from the punches to vary the spacing between the edge of the paper abutted against the edge stop for punching and holes formed therein by said punches, a stem rotatably mounted on the base and nonrotatably carrying the cam disc at one end and an actuating element on the other end of the stern constituting means for rotating the cam disc about an eccentric axis, the stem being longitudinally slidable relative to the base and resilient means for urging the stem to cause the actuating element to bear on the base, with the actuating element and the lbase having interengageable means for locating the actuating element and hence the cam disc in a plurality of predetermined positions.
BRIEF DESCRIPTION OF THE DRAWINGS An example of the invention is illustrated in the accompanying drawings in which FIGURE 1 is a side elevation of the device, FIGURE 2 is a plan view of the device, FIGURE 3 is an enlarged fragmentary section taken on line 3-3 in FIGURE 2, and FIGURE 4 is an end elevation of the device.
DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings the device includes a base comprising a diecast body 10, a sheet metal underplate 11 and a tray 12 which is clipped on to the underplate 11. The underplate 11 is secured to the body 10 by means of rivets 13.
The body 10 has a pair of spaced upstanding lugs 14 which are drilled slidably to receive a pair of punches 15. Pivoted to the free ends of the two lugs is a U-shaped operating member 16 which is coupled, by pin and slot connections 16, to the punches 15 for driving these components toward the base on depression of the operating member 16. The punches 15 co-act with holes 17 in the underplate 11 in such a manner that the paper discs formed when holes are punched in paper inserted between the punches 15 and the underplate 11 are caused to fall into the space between the underplate 11 and the tray 12.
Locating means are provided for locating papers on the base for punching. The locating means includes a paper edge stop 18 in the form of a thin sheet metal pressing. The edge stop 18 is slidably located between the body 10 and the underplate 11 and has a ange 18a at one end underlying the lugs 14 and forming the actual stop against which the edge of the paper is, in use, abutted. The edge stop 18 is guided in its sliding motion by means of a pair of projecting portions 18b on the llange 18a which are engaged in grooves 11a formed in the underplate 11.
The edge stop 18 is movable by means of an actuating element in the form of a lever 19. This lever 19 has an integral stem 20 running in a bore in the body 10 and a spigot 21 of noncircular section on the end of the stem. The spigot 21 is a non-rotatably engaged in an eccentric hole in a circular cam disc so that the cam disc 22 is rotatable by means of the lever 19. The cam disc 22 is engaged in a anged hole in the edge stop 18 and thus rotation of the lever 19 will cause movement of the edge stop 18 towards or away from the punches 15.
On the lever 19 there is a V-shaped abutment portion 23 which can t into similarly shaped grooves formed in the bottom of a counterbore in the body 10. A bowed spring washer 24 is itted between the cam disc 22 and the underside lof the body 10. Thus the cam can be located, by the action of the spring washer 24 urging the abutment 23 into the grooves, in a plurality of distinct positions. In the present example there are, in fact, tive such positions separated by 45, although it is to be understood that other arrangements could be employed.
A label 25 is preferably attached to the body 10 and is provided with index marks to which the lever 19 is directed when in its various positions. The label is printed with symbols indicating the distance of the holes to be punched from the edge of the paper when abutted against the edge stop.
As shown in FIGURES 1 and 2, the device also includes an adjustable end stop 26. The end stop is carried on the end of a bar 27 inserted through holes in the underplate 11 and acted upon by a spring brake (not shown).
With the device described above the width of the margin of a punched paper can be adjusted according to the requirements of the user. Thus papers can be so punched that they are neatly aligned with the other papers when assembled in a ring book, box le or the like.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
