BUNDLING TOOL Filed June 9, 1933 1 NVENTOR: QURRV ORA 'WALRER ATTORNEY.

Patented Feb. 12 1935 V UNITED STATES PATENT, OFFICE BUNDLING TOOL Curry Ora Walper, Hamilton, Ontario, Canada Application June 9, 1933, Serial No. 675,018 z claims. (o1. 1-1-59) This invention relates to improvements in packaging or bundling structural-elements, such as plaster boards, wall boards or the like, and has for its principal object to provide means for conveniently and efliciently applying bundling clips or the like to stacks of such elements.

Another objectof the invention is to provide a clip-applying device which can be simply and cheaply manufactured, and by means of which the clip may be quickly applied to the stack.

The invention consists in the novel details of construction hereinafter described and more fully set forth in the appended claims.

A preferred form of the invention is shown in the accompanying drawingQin which L Figure 1 is a side elevation of the device showing clip in place and in process of application to a stack of boards or structural elements;

Figure 2 is an end elevation, and

Figure 3 is a side'elevation of the device with clip in final stage'of application to the stack;

The device consists essentially in a clip-holding and positioning spring member 1, a handle 2, a supporting plate 3 and a buffer plate 4 between which the spring member 1 may be gripped by means of threaded studs 5 and nuts .6. The plate 3 may be integral with the handle 2/ The ends of the spring member 1 are bent inwardly, as shown, and terminate in fiat opposing surfaces l' to form a jaw 7 adapted to engage the end of a stack of boards or other such elements 8.

The clip 9 illustrates the type of clip which may be applied by the present device. It will be noted that it is substantially V-shaped in longitudinal section, the end portions 10 thereof being normally bent inwardly'towards each other so that they must be, somewhat spread apart when applied to the stack and when released will efiect a gripping action, particularly on the top and bottom elements of the stack. The clip may also be provided with prong-like extensions 11 adapted to engage the end faces of individual elements of the stack.

In use, the clip 9 is inserted in the device by pressing the surfaces 1' towards each other and placing the clip thereon so that the end portions lo engage the outer portions of surfaces 1', as shown. The jaw 7 is then applied to the end of a stackof boards or thelike 8 and a push exerted on the-handle 2, whereupon the flat surfaces 1' are forced apart, together with the end portions 10 of the clip, until they ride on opposite sides of the stack, as shown in Figure 1. As the push is continued, the surfaces 1' slide out of engagement with the portions 10 of the clip, which then engage the sides of the stack, and the buffer plate 4 engages the outer surface of clip 9 and forces the same into close engagement 7 with the edge of the bundle or stack, the prongs 11 piercing the edges of the individual elements, as shown in Figure 3.

The device may be easily disengaged from the stack by exerting a quick pull on the same, the inclined end portions 10 of the clip permitting the ends I of the spring member to slide easily over the ends of the clip.

It will be noted that the device may be easily assembled and disassembled and that the few individualv parts are simple and inexpensive in manufacture.

I claim: V

l. A device for applying packaging or bundling clips to a stack of structural elements consisting of a handle, a spring member mounted upon the handle and bent upon itself to form an expansible and contarctible jaw for engagement within a clip to hold and expand the latter, and a buffer member'carried by said handle mounted between the handle engaging portion of said spring member and said jaw for engaging a clip carried by said jaw and forcing said clip on to said stack upon application of pressure to said handle. g

2. A device for applying packaging or bundling clips to a stack of structural elements consisting of a spring member bent upon itself to form a jaw with a flared opening, the free ends of said member being spaced apart to engage within a clip, and a handle secured to said spring member at its central portion opposite said jaw.

CURRY ORA WALPER.
