s Claims. (c1. 1s6) This invention relates to the ypower driving of nails and thelike wherein a plurality of nails may be successively fed and delivered and driven automatically, with the application of a tool to the work. y

The instant application is a continuation-impart of applicants co-pending application, S.N. 530,514, filed August 25, 1955, entitled Power Nail Driving Tool. The instant application has specic relation to the peculiar and novel structure of and to the production of multiple nail clips and feeding means which provides for very eicient loading of nail magazines in nail hammering devices and to the precise and successive feeding of nails to a power hammer. Some forms of said multiple nail clips were disclosed in our said application.

It is an object of our invention to provide a simple, inexpensive but highly ecient multiple clip of nails partive tiers of nails.

2,909,781 Patented Oct. 27, 1959 heads of the nails of conventional type, successively overlapping from the bottom of the clip to the top or outermost portion. The shanks or pointed ends ofthe nails converge from the rear or head ends of the nails tothe point. This is a very important arrangement and-structure to accomplish applicants purposes. The'tiers of nails precisely arranged, as described and illustrated, are preferably bonded together into a unitary "clip construction through the employment of suitablebonding materials, such as plastic resins or rubber base bonding material. i

In Fig. l, the forward or tip portions of the nails wherein the interstices are minimum, are shown as bonded together through dipping of the nails held in proper tier relation. y

In Fig. 2, application of plastic by spray nozzles having a gyratory movement to produce an initial webbing of the discharged plastic is illustrated. Thev bonding is applied at the medial portions of the nails from both sides thereof. v

In Fig. 3 another form of rnultipleunail clip is shown where the head and rearward portions of the nails are bonded together, either by dipping in suitable bonding material` or by application of the bonding material through spray nozzles from opposite sides of the respec- The bonding material utilized is of a nature ,to facilitate ready fracture and comminution thereof, particularly when a force is applied to the lowermost or innermost nail of the clip in a direction longitudinally thereof.

Thus, a friable non-sticky bonding material which may ticularly designed for combinative use with a hammering gun which feeds by reciprocating parts longitudinally of a barrel.

A further object is the successful and commercial manufacture of unitary multi nail clips wherein the successive nails are staggered as to the head portions thereof and are arranged and bonded together with the shank and tip portions converging. Such structure facilitates greatly, the successful and efficient feeding of 'the nails successively into a hammering gun.

These and other objects and advantages of our invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the Same or similar parts throughout the several views and in which:

Fig. 1 is a side elevation of one embodiment of nail clip wherein the forward portions of a plurality of nails are bonded together from the tips inwardly;

Fig. 2 is a similar elevation showing another form of our improved clip;

Fig. 3 is a side elevation showing still another form of clip;

Fig. 4 is a View mostly in vertical section showing one of our clips operatively positioned in the magazine of a nail-hammering gun and showing most of the feed mechanism which is operated through reciprocation of the barrel of the gun relative to a stationary sleeve connected with the handle.

Referring now to the drawings, the combinative structure, arrangement of nails and operation of our new multi nail clips are novel and improved, as contrasted with anything in the known prior art. This structure is responsible inherently for unexpected, new and materially improved results in comparison with any of the prior art structures, particularly lending itself to high efliciency for reciprocating type feeding mechanisms for nail-hammering guns. As shown in all of the forms illustrated in Figs. l to 4 inclusive, a plurality of nails, as shown a-t 12, are arranged in each instance in tier formation in a substantially common plane with the constitute thermo setting and other non-thermo setting plastics, is foundl highly etiicient'. Vinyl plastic, for example, is satisfactory.

The particular head-overlapped and merging shank relationship of the nails in our clipsy is particularly important in producing new and improved results. First, in combination with a holder or magazine to guide the sides of fthe shanks lwith the lnails, the innermost'nail of the clip will always be guided from above bycontact of the head and forward shank portion of the lowermost nail with the necessarily declined shank of the nail immediately above. If the nails were not arranged in overlapped head relation with the pointed ends converging the guiding edge of the nail aboveiwould be disposed substantially horizontally and no downward component of travel would be effected through any guiding of the nail above.

Secondly, if the heads of ordinary nails were vertically aligned, when the lowermost nail is released, a lateral jumping movement of the nail would occur during forward pushing of the lowermost nail after the heads of adjacent nails became disaligned. To better Aillustrate the foregoing points, reference-is made to Fig. 4 of the .drawings which shows a portion of the magazine and the feed mechanism and rear portion of the barrel of a power nail driving tool disclosed in our co-pending application S.N. 530,514. In this structure, a stationary sleeve 10 attached to a handle or mounting for the gun has slidably mounted in the outer portion thereof, a barrel 12 wherein a reciprocating hammer rod 11 is mounted. Hammer rod 11 is actuated by mechanism, not shown, usually mounted in the handle or mounting of the gun. The magazine indicated as an entirety by the letter M. is aiiXed to the barrel 12 by mounting means not shown, which extend through slots in the sleeve 10 so that the magazine slides with thebarrel upon the sleeve. The magazine includes a pair of vertical side members 13 which are slotted obliquely at 13a to receive the heads only of the nails N. The sides 13 of the magazine are spaced apart to nicely accommodate the clip of nails or nails in tier formation arranged in Y i the manner illustrated. The magazine is fed with clips through a hinged rear door 14 and a spring actuated follower plate 15 having trunnions or mountings arranged in slots 13b of the sides 13 urges the diverging tier or clip of nails downwardly or inwardly and through an elongated nail passage 10a formed in the appropriate portion of sleeve 10, at the bottom of the magazine.

The external portion of barrel 12 is provided with a nail-guiding groove 12a which uniformly increases in depth from the rear portion of barrel 12 towards the intermediate portion thereof, communicating with a nail slot 12b which extends laterally through the top of the barrel and is of a width and length to nicely accommodate ordinary nails varying to some extent in length and diameter.

A roller dog or other dog 16, the outer end of which is spring impelled downwardly cooperates with the forward end of the nail during feeding to urge the same downwardly within the bore of the barrel 12.

It will be seen that with our improved nail clip the lowermost nail Within the barrel 12 is slid rearwardly relative to sleeve 10, is engaged by an abutment 1Gb which helps to define the nail passage 10a, being thereby forced forwardly relatively to the barrel and broken away from its bonded engagement with the nails lying above in the bonded clip formation. The lowerrnost nail guided by the vertical sides M of the magazine and with its head guided by contact with the underside of the nail immediately above, is always positioned and guided in a declined, straight line relationship since the nail immediately above due to the merging arrangement of the shanks of the nails, is always declined with reference to the axis of the barrel. Consequently, the lowermost nail as it is fed, is precisely guided forwardly and directly and cannot jam in the forward end of the apertured portion 10a of the sleeve, but will nicely be guided in an effective manner along the forwardly declined nail channel 12a.

From the foregoing description, it will be seen that we have provided highly efficient multiple nail units or clips having the nails specifically arranged and bonded together in a predetermined structure and relationship which is highly ecient for combinative use with a nailhammering gun which feeds through reciprocation of parts longitudinally of a barrel.

It further will be seen that our improved multi nail unit or clip may be easily handled, packaged for shipment and applied to the magazine of a nail gun.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of our invention.

What is claimed is:

1. A multiple nail clip comprising a multiplicity of headed nails arranged in tier formation, one above the other with the heads of successive nails from the inner side of said unit outwardly successively overlapping and with the shank portions near the tip ends thereof positioned at least close to abutment, thereby producing a converging of the shank portions of all of the nails in a predetermined zone extending transversely of the Shanks, bonding means interconnecting correponding portions of said nails, said bonding being of frangible, non-sticky material and interconnecting the nails in a rigid manner.

2. The structure set forth in claim 1 and the heads of said nails being substantially in overlapped abutment.

3. The structure set forth in claim 1 and said bonding being present and applied to opposite sides of said tier formation.

4. A multi nail clip comprising a predetermined number of headed nails arranged in tier formation with said nails being related, one above the other, and with the heads thereof successively overlapping from the innermost nail of said unit, the shank portions of said nails adjacent the tip ends thereof being substantially in lateral abutment whereby said nails converge `from the head portions thereof toward the tip portions thereof.

5. A multinail clip comprising a predetermined number of headed and pointed nails, all oriented in the same direction and frangibly bonded together substantially in planar relation, each of said nails in the clip forming with a juxtaposed nail, a narrow space converging from the heads to the points thereof, one of said nails and its juxtaposed nail having their heads misaligned in close overlapping relation, one being slightly forward of the other with respect to their forwardly disposed points.
