M E'rnon or DRIVING STAPLES v Desmond R. La'llace, Pittsburgh, Pa., assignor to Bocjl Corporation, a corporation of Delaware y Application September 3, 1942, Serial No. 457,166
8 Claims.
This invention pertains to the art of stapling and isa continuation-impart of my copending Vapplications Serial No. 386,497, filed April 2, 1941 for improvements in kFasteners and method of fastening and Serial No. 386,498-, led April 2, 1941 for Stapling hammer. The invention is also related to my copending application Serial No. 457,165, filed September 3, 19,42 for Method and apparatus for stapling. v
In the iirst of the foregoing applications there is disclosed a staple having a top portion which is connected to substantially parallel leg portions through relatively small extensions forming connections between the legs and the head. The head and the legs are normally in substantially a plane so that the fasteners may be arranged in rows in face to face relation. Moreover, the fasteners are shaped'so that the rows may be arranged when desired in point to back relation with the head portions of the staples of one row extending up between the legs of the staples of the row above. These staples are designed to be driven by effecting relative rotation between the head portion and the leg portion of each staple until the head portion is at substantially right angles to the legs. The head then presents a relatively largev surface to the underlying material and such staple is intended to replace large headed nails or tacks such as those used for securing roofing or sheathing paper to a wooden structure or such as the tacks used for securing upholstery to a wooden frame. I refer-to such staples as tilt-top staples. 1
In the second application above referred to, I have disclosed a driving tool in the form of a hammer for driving staples of this type. In the specific form of hammer illustrated the staples are delivered one at a time to the-guide of the stapling tool. They are engaged by a driver which simultaneously starts to drive the staple 4and rotate the head relatively to the legs. Be-
fore the staple has been completely driven the rotation of the head has been completed vand in the final operation the head of the staple lies fiat against the surface into which the staple has been driven. In the third application above referred to the head of the staple is confined in a plane while the legs are turned relatively to the head. This is accomplished asa step in the driving operation but the movement of the legs of course occurs before the points of the legs have penetrated the surface into which they are to be driven. The said application is specific to that particular method and to a driving tool for accomplishing that method. l f
'The present application is directed generically to the method of kstapling wherein relative rotation is effected between the head and the legs of the staple to turn the head from the plane of the legs to a plane substantially perpendicular .to the legs. It is directed specically to the method which comprises rotating or tilting the head relatively to the legs and more especially to the method of accomplishing the turning of the head and the driving of the staple in a single stroke of the driver.
The invention may be more fully understood byreference to the accompanying drawing,in which:
Figure 1 is a front elevation more or less schematically showing a stapling tool with thestaple in place therein in position to bedriven, part of the tool being shown in section;
Figure 2 is a'transverse vertical section through Figure 1, the staple, however, being shown in elevation; Y
Figure 3 is a transverse horizontal section in substantially the plane of line III- III of Figure 1, the top plan elevation of the staple being shown;
Figure 4 is a view similar to Figure 1 showing the beginning of the driving of the staple.;
Figure 5 isa view similar to Figure 2 showing the beginning of the driving of the staple;
Figure 6 is a View similar to Figure 5 showing a further step in the driving of the staple in which the head of the staple has been turned;
Figure 7 is a View similar to Figure 4 but showing the completion of the driving stroke;
Figure 8 is a top plan view of the staple after it has been driven;
Figure 9 is a view similar to Figure 1 in which the staple is illustrated as being formed of wire; and
`V.Figure 10 is a view similar to Figure 5 showing la step in the driving of a wire'staple.
Referring first to Figures 1 to 8, inclusive, the staple or fastener designated generally as 2 has substantially parallel legs 3 and a disk-like top 4 which is narrower than the distance between the legs. The top orhead of the staple 4 is connected with legs through lateral extensions 5. The head and the legs, as clearly shown in Figure 2, are substantially in a plane.
The driving tool, designated generally as 6, comprises a guide having parallel side members 1 in'which reciprocates a driver 8. The inner faces of the guides 1 are provided with' grooves or channels 9 as best shown in Figures l1 and 3, these channels being deep enough to receive the-legs pushed down fbyetheidriver.
