Application December 24, 1953, Serial No. 400,214

3 Claims. (Cl. 248-71) This invention relates generally to improved staples for holding pipe, wire and the like. Most staples have a hook to hold the object and a piercing stem and a head for driving the same into the body for holding the object thereon. Some staples are made with a single stem and some are made with two stems, however, most staples are difficult to drive owing to the fact that the bend of the hook is employed to drive the same and is uppermost on the staple. Other staples provide a driving head above the hook and a stop below the hook for limiting the penetration of the stem into the object into which the staple is driven.

The staples of the prior art are diflicult to hold while being driven. Either the driving head is too close to the hook or the edges of the material from which the staple is made must be grasped between the fingers and is difiicult to hold as it flips out of ones grasp, particularly upon the first blow of the hammer when driving the staple.

The principal object of this invention is the provision of a simplified staple structure which provides a driving head and a stop that cooperate to form a gripping seat, which when grasped between the fingers may be firmly held while being driven.

Another object is the provision of a staple made from a single piece of material doubled back on itself to form a driving head, a stop and a hook member and providing a finger grip to hold the staple while driving.

Another object is the provision of the staple having a double stop and a single driving head, stops being located at opposite ends of the hook.

Another object is the provision of the staple having a driving head, stop and spaced pointed stems, one directly beneath the driving heads, and the others beneath the opposite ends of the hook.

Another object is the provision of the staple having a dual driving head, a stop and a dual hook therebetween.

Other objects and advantages appear hereinafter in the following description and claims. 7 'The' accompanying drawings show for the purpose of exemplification, without limiting the invention or claims thereto, certain practical embodiments illustrating the principles of the invention wherein:

Fig. 1 is a view in side elevation of a staple comprising this invention.

Fig. 2 is a view in side elevation of the staple wherein the end of the hook also functions as a stop.

Fig. 3 is a view in side elevation of a staple wherein the end of the hook is provided with a driving point.

Fig. 4 is a View in side elevation of the staple having a dual driving head and stop with a hook therebetween.

Fig. 5 is a view in side elevation of a staple having a dual driving head and stop with dual hooks looped therebetween.

Fig. 6 is a plan view of the strip showing staples being blanked therefrom.

Fig. 7 is a view in side elevation of a staple made from the blanks of the strips of Fig. 6.

Fig. 8 is an end view of the structure shown in Fig. 7.

Fig. 9 is a view of a staple having its hook holding an object of circular cross section.

Fig. 10 is a view of the book of Fig. 9 being opened to hold an object of larger diameter.

Fig. 11 is a view of a staple having its hook at right angles to the stop bend.

Fig. 12 is a side view of the staple of Fig. 11.

Fig. 13 is a view of a staple having its hook of doubled wire.

Fig.14 is a side view of the staple of Fig. 13.

Fig. 15 is a view in front elevation of the staple having its hook at right angles to the plane of the stem and the intermediate portion.

Fig. 16 is a side view of the structure as shown in Fig. 15.

Fig. 17 is a view of the under side of the staple shown in Figs. 15 and 16.

Referring to Fig. 1, the staple 1 comprises the stern portion 2 having the pointed end 3 and the driving head 4 at its upper end and is formed by bending the wire back on itself as indicated at 5. The stop 6 is formed by putting a reverse bend in the wire to form the hook 7 which terminates at 8 which would be spaced above the plane 9 of the surface into which the staple is to be driven.

Staples of this character may be made out of wire similar to that employed in the manufacture of nails. The wire may be of ordinary nail wire or it may be galvanized or it might be a wire coated with a copper or other material to avoid rusting, corrosion or electrolysis when used in combination with other metals. If the coating is the same metal as the surface of the object to be held the question of electrolysis is eliminated.

The folding of the stem 2 back to form the section 5 together with the folding in the reverse direction to form the hook 7 provides three sections of the wire in alignment such as indicated at 10, 11 and 12, which provides a finger grip for grasping and holding the staple while driving the same by striking it on the head 4. This wire thus turned back on itself provides a very firm gripping surface, and since the driving head 4 is above and the stop 6 is below the finger, the staple may be readily held, without injury thereto when driving the same with a hammer or other blank instrument.

Referring now to Fig. 2, the staple 13 has the same sections as the staple 1, however, the hook member 7 has been extended to provide a stop at 14 which is at the same elevation as the stop 6.

In the structure as shown in Fig. 3 the staple 15 is similar to the other staples although it is provided with an extension 16 of the hook 7 that is pointed on its end as indicated at 17 and thus provides a piercing point on the end of the hook which will be partially inserted into the surface of the member into which the staple is driven for aiding in locking and holding the object under the hook against accidental movement.

Referring to Fig. 4, the staple 18 is provided with a second driving prime member 2' with its pointed end 3' and driving head 4' and stop 6 which connects to one end of the hook member 7 that extends between the stops 6 and 6. A staple of this character, of course, has greater strength in holding the object on the member into which it is driven owing to the fact that both stems are of equal length and are intended to penetrate the member until the stops 6 and 6', which are at the same elevation, engage the surface of the same.

The structure as shown in Fig. 5 is similar to that shown in Fig. 3. However, the staple 20 is provided with a dual hook 21 and 22 holding two pipes or wires that run parallel with each other. By straightening out the bend between the hooks 21 and 22 one may be nose -es with one long hook for securing a plurality of objects between spaced stems 2 and Z.

The staples as previously described are constructed of wire material whereas the staple as shown in Fig. 6 is stampedtront sheet materiat, thesheet being. indicated at 23.1mm the staples being cut with a stern; having a pointed ,endHZS and a wide hook section. When shaped in the form of a stapleflthe lower endfof the stem 24 is creased as indicated at27 to stiflen the same and make it smaller as indicated in Fig; 8. The other sectio 28 of the stem24 is utilized in the sections forming the driving head 30 and the stop 31 as shown in Fig. 7.

in each of the structures it is preferable to have stop. Bend 42 is preferably somewhat higher than the bend 44 to form a striking head 40 and the bend 44 being slightly lower provides a surface for engaging the member to be held.

Referring to Figs. 15, 16 and 17, the staple 50 is pro vided with the pointed stem 2 having at its upper end the driving head 4 formed by the first bend and the stop 6 formed by the" second bend, the two bends being connected by the intermediate section and the hook memthe striking head extend above the hook or holding strip of the staple as a hammer is apt to bend the hook or otherwise destroy the pipe if the driving head; is close to the surface of the hook or the pipe which it holds.

It will be noted from Figs; 6, 7 and a that the stem 24 when bent back on itsclfin the same manner as wire staples previously described, will provide a series ofedges in alignment with each other in the same manner as that, illustrated in Fig. 1 to provide a finger grip which will not permit the staple to be flipped or turned in the fingers whilebeing driven.

Referring specifically toFigs. 9 and 10 the staple132 is shownin both figures wherein the hook member 7 is in the plane of the bend. The hook 7 is made to hold thecircular object 33 which fits the inner curvature of, the hookmember 7. In Fig. 10 the object 34 is much larger in diameter than the object 33 and thehook has been ,held on theedgeofa support and struck with a hammer to open the same so that it may still engage the: larger diameter object 34 and the end 8 is over the top? center of the circular object 34, thus the staple. as shown in 9 and 10 is capable: of adjustment by means ofthehammer on the job for holding a series. of sizes of obiects. Of course, when the sizes of' the objects are too remote, it isneoessary to provide a staple nearento thesize of the object tobe fastened.

In the structure shown in Figs. 11 and 12 the staple is formed with the stem 2 bent at 4 to form the head, and produce the section Sand the plane of the hook member 7 is formed at 90 degrees from the plane of the bend .4, the bend being somewhere along the section 5 between the bends 4 and 6. The bend 6 formsthe stop 1 as before, however, the section 5 is moved outwardly so that the stem 2 is substantially tangent to the inner arcuate surface of the hook 7 as indicated at 36.,

In the structure asshown in Figs. 13 and 14 the staple 37 is provided with the stem 2 which is bent over as indicatedat 38 to form the (flat head 40, and is then bent downwardly as indicated at .41 to complete; the hook member 42. The bottomof thehook as indicated at 43 is bentbackwardly on itself to form another section 44 of the hook member which has an apex at .45 and terminates at 46. If the end 46 is below the point 43 it functions as a stop. If the end 46 is at the same elevationas the section 43 either may function as a whom i ber 51 which extends upwardly from the bend 6 at right angles to the plane of the stem and the section 5. In other words, the hook member is formed at by merely turning the end laterally of the plane passing through the stem and the intermediate section 5. The end of the hook 51 is indicated at 8. This hook member is very similar to the hook member, shown in Figs. 11 and 12, with the exception that in the latter, the hook member is turned in a. 90 plane through the intermediate section 5, whereas in the present case the hook member is formed by merely bending the section laterally from the plane passing through the aligned stem 2 and intermediate sec: tion 5.

I claim:

I. A single wire staple comprising a stem having a point at one end and at its other end a fold turned back on itself in one plane to form a driving head, a second fold in the wire turned back on itself and spaced from said first fold but short of said point and lying in said first mentioned plane to form a stop adjacent said stem, an open bend in the wire extending upwardly from said second fold then downwardly to form a hook, in said first mentioned plane and providing with said first and second folds a wide finger grip below said head and above said stop, the top of saidhook being lower than the top of said head and higher than said stop. i

2. The staple of claim 1 which also includes a third fold in the wire beyond said hook and turned back on itself in said first mentioned plane to format second stop, and a fourth fold in the wire .back on itself in said first mentioned plane to form a second head, and a second stem that extends downwardly below said second stop.

3.The staple of claim 2 characterized in that a plurality of hooks are formed in said first mentioned plane between said stops.
