2 Claims.

This invention relates to a stapling machine, the general object of the invention being to provide a simple device for forcing staples through sheets of paper or the like and bending the limbs of the staples over so that the vstaple will connect together the sheets.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a side view of the device.

Figure 2 is a section on the line 2 2 of Figure 1.

Figure 3 is a bottom plan view of the die member.

Figure 4 is a plan view of the staple holding means.

In this drawing, the numeral I indicates the base of the device which has an upright 2 at one end to which ise pivoted the downturned end 3 of the handle member 4. A die member 5 is fastened to the under face of an intermediate part of the handle member 4 by the screws 6 and this member is provided with the double curved grooves 'I for bending over the limbs of a staple pressed into the grooves.

The holding means include a pair of elongated upwardly from the base into the slot I I when the plates 8 and 9 are in raised position and the upper end of this plate I5 forms a seat for the staple. This plate l5 has a horizontal part I5 at its lower end which is fastened to the top of the base I by the screws I5 as shown in Figures 1 and 4.

. nected together are As will be understood when the device is to be used a staple is placed in the slot II so that it will rest on the upper end of the plate I5, as shown in Figure 2 and then the sheets to be conplaced over the staple supporting means and under the handle. Then the handle is depressed so as to force the plates 8 and 9 downwardly and to cause the ends of the staple to pass through the sheets and be engaged by the curved parts of the grooves 'I which acts to bend the limbs over upon the sheets and thus the sheets are firmly connected together by the staples.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having described the claimed as new ist- 1. A stapling machine comprising 'a base, a

invention, what is spring-pressed part.

2. A stapling machine comprising a base, a handle pivoted to the base, an upsetting die carried by the handle, an upright plate having its lower part connected with the'base, said base the base, spring means engaging the shanks for holding the plates and the shanks in raised position, said of the upthe small plates are arranged, connecting the long plates with the small plates to form a socket into which the upright plate extends.
