MAGAZINE-HAM MER'.

SPEGIFIGATION forming part of Letters Patent No. 678,062, dated July 9, 1901.

' Application filed February 28, 1901- Serial No. 49,209. (No model.)

To aZZ whom it may concern:

Be it known that I, GROVE S.TARBELL,a citizen of the United States, residing at Lockport, in the county of Will and State of Illinois,have invented certain new and useful Improvements in Magazine-Hammers, of which the following is a specification.

The object of this invention is to produce a magazine-hammer which will carry a large number of tacks or nails, and, through the medium of a simple and effective mechanism, to regulate the feed thereof and position the same so that they may be readily set or struck into an object with sufficient force to hold the tack in place for driving, the operation of feeding the tacks being automatic and the supplying and setting of them being accomplished with one hand, leaving the other free to hold the work which it is desired to secure in place. To this end the handle is constructed to carry the tacks and contains mechanism for successively feeding the same out of the magazine thereof and into proper position for setting them into the object, the parts which control and regulate the feeding of the tacks or nails constituting a closure for the handle forming the magazine and providing an anvil or platen to support the tacks and enable the operator to set them in position.

The hammer is further provided with an adjustable seat, whereby the same may be used with tacks or nails of different sizes without having the ends thereof project unduly beyond the head.

The hammer is further provided with a magnetized seat by which the bodies of the tacks are held in proper position for setting and are prevented from escaping from proper position, from which, however, they may be readily drawn after. being properly set.

A magazine-hammer which may be operated entirely with one hand is very serviceable in tacking laths, in laying carpets, and for other classes of work where it is required that one hand of the operator shall be free to hold the work it is desired to tack in place.

My invention therefore contemplates the production of ahammer which will fulfil these requirements in a simple and-effective manner.

The following specification is a detailed description of my invention, reference being .when the latter is in use.

had to the accompanyingdrawings, and to the reference-numerals thereon, which indicate the different parts, and in which- Figure 1 is a perspective view of a hammer embodying the principles of my invention.

Fig. 2 is a side elevation of the removable head, with the handle in section. Fig. 3 is a cross-section on the line 3 3 of Fig. 2. Fig.

4: is a plan View of the removable head and cylindrical in cross-section for a suitable portion of its length to provide a magazine 3 for receiving a' supply, of tacks or nails. The

magazine is .formed with a longitudinal slot 4, preferably running throughout its length and on the under side when considered with re* lation to the position assumed by the head The handle is provided with suitable depending guards 5, which extend along the longitudinal slot to protect the operators hand from the projecting nailbodies and which form a raceway in which the bodies of the tacks or nails travel, their heads being confined within the magazine, as

shown in the drawings.

The open end of the magazine is provided with oppositely-disposed slots 6, extending back a suitable distance and arranged in a plane transverse to the plane of the feed slot 4 to receive the means to hold and retain the plug 7 in position, each slot 6 being in the form of a bayonet-slot or having a downwardly-projecting recess 6,arranged at a suitable distance from the end of the handle for a purpose to be presently described. The plug 7 has a substantially circular block of metal adapted to enter and close the bore of the handle at the open end of the magazine and is preferably flattened at its lower portion 8 when considered with relation to the position assumed by the device in use. The plug 7 is provided with a central bore or recess 7 which receives a magnetized seat 9, pivoted therein upon a pin 10, which extends out upon each side beyond the plug andis adapted to enter and traverse the slots 6 of the handle. The seat 9 is provided with a second pin 11, which also extends upon each side beyond the line of the plug, which is provided with slightly-elongated slots 12 to permit the passage of the same and allow a certain amount of play for a purpose to be hereinafter described. The bore or recess of the plug is somewhat larger than the seat 9, which is forced downwardly therein by any suitable means, such as the spring 13, which preferably is attached to the seat and bears against the bore of the plug to normally hold the pin 11 in the lower portions of the slots 12 when the parts are assembled. The seat extends out beyond the end of the plug and is grooved or substantially trough-shaped in cross-section and preferably is provided with upwardlyprojecting cars 14: at its end to accommodate and hold the body of a nail or tack. The exposed end of the seat is provided with a suitably-magnetized plate 15, preferably of the form shown in the drawings, which is arranged in the seat to permit a portion of the body'of the nail or tack to be in contact therewith as it lies between the ears in the groove of the seat. The flat portion of the plug is provided with a rib 7 which is formed with a channel on its under face adapted to register with the feed-slot of the magazine when the plug is in position. A pair of jaws 16, preferably in the form of light leaf-springs, are attached to the sides of the rib of the plug, and their front ends are Wider than their bodies and wider than the rib and extend outwardly in front of the rib and beyond the line of the plug, where they are bent inwardly toward each other to form shoulders to retain the heads of the tacks or nails with their bodies in position upon the seat, as shown in Figs. 3, 4, and 5, but allow them to be readily detached therefrom. The recesses 6, connecting with the slot 6, form bayonet-slots to receive and retain the pin 11, which is carried by the seat 9. The seat may be adjusted within the plug and so within the bore of the handle to regulate the size of the seat provided by the extended portion 9 and the jaws 16, whereby the device may be adj usted to accommodate tacks or nails of various sizes. The seat 9 is provided with a plurality of perforations 9 and 9 respectively, for receiving the pins 10 and 11, respectively, these pins being removable and insertible within either perforation of their series. These perforations are arranged in uniform order, so that when the pin 10 is in either of its perforations the associated perforation for the pin 11 will be in line with the slots 12, thus permitting the plug to be locked within the bore of the handle in either position of the seat. It is obvious that the ears 14c of the seat are nearer to or farther from the springs or jaws 16, according to the position of the pins 10 and 11 within the perforations in the seat, and that the trough is adjusted to regulate the length of the seat to accommodate any desired size of nail, such as a shingle-nail, ora smaller size, such as a tack. It is of course desirable that the point of the nail or tack shall extend but slightly beyond the end of the seat, and by providing the adjustment for the seat the device may be employed with nails or tacks of different sizes without exposing their ends unduly beyond the seat portion.

From the foregoing description in connection with the accompanying drawings it will be apparent that the plug is bodily removed from the bore of the handle to allow a quantity of tacks or nails to be placed within the magazine and that after the magazine is closed by inserting the plug the bodies of the nails or tacks will fall into position within the feedslot, and as the handle is brought into substantially a vertical position by the operator they will slide or feed toward the plug 7, and the formost one of them will pass into the channel in the rib of the plug and into the seat formed by the springs or jaws 16 and the magnetized trough 9, where the magnet will attract it and retain it in position with its head between the shoulders of the jaws and its body lying within the trough of the seat. The pointed end of the nail or tack will project beyond the seat, and its head will rest against the end of the rib 7 which thereby forms an anvil or backing for the same,whereby the operator may strike or set the nail or tack in the floor or lath while it is thus positioned, the anvil acting as a backing and permitting the operator to start the nail into the wood. When this operation is completed and the hammer is withdrawn from its setting position, the springs or jaws 16 will open to permit the head of the tack to pass out, and the operator then drives it home with the hammer-head, another tack moving to place on the seat.

Various changes may be made in the con struction without departing from the spirit and scope of my invention.' For example, the spring between the plug and seat may be replaced by a yielding packing, other connecting means may be provided for permitting the adjustment of the seat within the plug, and other forms of magnet may be pro-' vided.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a magazine-hammer, a hollow handle providing a magazine and having a feed-slot, a plug removably fitting the bore of the handle and having a seat to retain the nails or tacks.
