This invention relates to stapling machines employed in stapling sheet and/ or fabric material by the insertion of the prongs of a U shaped staple through the material and subsequently clinching the prongs.

The invention has as an object a stapling machine of the type referred to embodying a particularly simple and efiicient structure by which a plurality of staples may be inserted in the material in spaced relation from each other.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a side elevational view of a stapling machine embodying our invention.

Figure 2 is a view, similar to Figure 1, with the stapling head and anvil members moved into operative stapling engagement.

Figure 3 is a view, similar to Figure 1, illustrating the posiltion of the parts during the insertion of the second stap c.

Figure 4 is a side elevational view of the machine with the parts arranged at the completion of the stapling operation.

Figure 5 is a top plan view of the machine indicated by line 5-5, Figure 1.

Figure 6 is an elevational view indicated by line 6-6, Figure 1.

Figure 7 is a sectional view taken on line 77, Figure 1.

Figure 8 is a face view of a tag stapled to fabric material by our machine.

Referring to Figures 1 to 4, the frame of the machine consists of a base plate on which there is mounted a pair of side plates 21 and a vertical plate 22 extending upwardly from the side plates. The stapling head 23 is supported by a pin 24 extending through the lower end of the stapling head and through a side plate 21, the head being operatively positioned by a bracket 25 carried by the rear plate 22.

The clinching anvil 26 is mounted upon the upper end of an arm 27, the lower end of which is pivotally mounted between the side plates 21 on a pin 28. The anvil is formed withtransversely extending grooves, or clinching surfaces 30 arranged in registration to receive the prongs of the staple 31 ejected by the head 23 and inserted through the material to be stapled. The arm 27 is provided with a pair of laterally extending panels 33.

The material 35 to be stapled is positioned or draped over the face of the anvil 26 by a support member 36 having depending sides 38. The support is pivotally mounted on the anvil 26 by screws 40 extending through the sides 38 and being threaded into the anvil, the top wall of the support extending rearwardly forming a handle 41. The forward portion of the support is a boxlike arrangement, the vertical opening of which is somewhat more than twice the vertical dimension of the clinching face of the anvil 26. The upper side of the anvil is formed with a recess in which is mounted a helical compression spring 44 yieldingly urging the handle portion 41 upwardly and the forward portion of the support downwardly against the anvil, as illustrated in Figures 1, 2 and 6. With the material support in this position, the arm 27 is moved toward the stapling head 23 and upon engagement therewith, a staple is inserted through the material, and the prongs of the staple clinched over by the clinching grooves 30. The arm 27 is then moved outwardly, the handle portion 41 of the support pressed downwardly, causing the material 35 to be shifted upwardly, as shown in Figure 3. As the arm 27 is again moved forwardly, a second staple is inserted through the material.

In the drawing, the machine is illustrated as stapling an identifying tag 46 to the material 35, this operation being commonly performed in laundries and dry cleaning establishments, the tag having indicia printed thereon to identify the material, or garment. Upon the second operation of the arm 27 with the material support moved to upper position, the second staple 47, Figure 3, is placed in spaced relation from the staple 31 inserted upon the first operation of the device.

In operation of the structure described, the garment or material 35 is draped over the end of the support 36 and is held in this position by the operator grasping the material against the handles 33. Upon the second forward movement of the arm 27, the operator depresses the handle portion 41 with his thumb, thereby effecting shifting of the material in a direction radial of the plvot 28 whereupon the second staple 47 becomes inserted through the tag and the material in spaced relation to the first sta 1e.

f n order to minimize the possibility of slippage between the material support and the material, or to increase the frictional engagement therebetween, the forward end portion of the material support is preferably encircled by a rubber band 48.

It will be apparent that by the addition of the simply constructed material support to the anvil of the stapling device, the material is quickly and conveniently shifted for the insertion of the staple in suitably spaced relation to the first staple.

What we claim is:

1. A stapling machine comprising a frame, a stapling head mounted in the frame, an arm mounted in the frame for movement toward and from the stapling head, an anvil carried by the arm and being formed with a clinch surface movable into and out of cooperative stapling engagement with the stapling head upon movement of said arm toward and from the head, a material support for supporting material overlying the clinch surface of the anvil, said material support being movable to shift the material in a direction radial from the pivot point of said arm.

2. A stapling machine comprising a frame, a stapling head mounted on the frame, an arm mounted on the frame for pivotal movement toward and from the stapling head, an anvil mounted on the free end of the arm and being formed with a clinch surface confronting the stapling head, a material support pivotally mounted on said anvil and being adapted to support the material being stapled over the clinch face of the anvil, said support being movable about said pivot to shift the material being stapled relative to the anvil.

3. A stapling machine comprising a frame, a stapling head mounted on the frame, an arm mounted on the frame for pivotal movement toward and from the stapling head, an anvil mounted on the free end of the arm and being formed with a clinch surface confronting the stapling head, a material support pivotally connected to said anvil and being adapted to support the material being stapled over the clinch face of the anvil, the axis of said pivoted connection extending perpendicular to the path of movement of the anvil toward and from the stapling head, said support being movable about said pivcilt to shift the material being stapled relative to the anv 4. A stapling machine comprising a frame, stapling head and anvil members mounted on the frame, one of said members being movable into and out of cooperative stapling engagement with the other member, a material support carried by said movable member for supporting the material being stapled, said material support being movable to shift the material in a direction perpendicular to the movement of said movable member for the insertion of a second staple in spaced relation to the first staple.
