LASTlNG-HAMM ER.

SPECIFICATION forming part of Letters Patent No. 594,997, dated December '7, 1897.

Application filed March 29, 1897- To all whom, it may concern:

Be it known that I, JOSEPH E. LEMYRE, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Lasting-IIammers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

It is a common practice among lasters to place a quantity of tacks in their months before commencing to last a shoe or boot, eX- tracting them one at a time as required during the operation. This practice is not only dangerous to health, but is dangerous to life. Still the practice grows and increases for the reason that time can be saved, and hence a days wages made larger than if a laster should take his tacks from a suitable receptacle near at hand.

The object of the present invention is to provide a substitute for ones mouth as a receptacle for tacks which shall make it possible for a laster to accomplish his work still more rapidly.

The invention consists in a receptacle for tacks which may be attached to either a hammer or a pair of pliers, and to certain novel mechanism whereby the tacks contained in said receptacle are fed and stuck one at a time where desired, ready to be struck by a handhammer, as fully set forth in the following specification and claims and clearly illustrated in the drawings, forming a part thereof, of which-- Figure 1 is an elevation showing one of my improved tack-reservoirs as applied to a lasters hammer, Figs. 2, 3, and 4 being details. Fig. 5 is a broken elevation showing that side of my improved lasters hammer opposite to that shown in Fig. 1. Fig. 6 is an end View of the tack-reservoir with its feeding mechanism, the hammer being shown with a portion of its handle in dotted lines.

Similar reference-letters designate corresponding parts in all the views.

A represents a hammer-head, and B is its handle, to which my improved tack-reservoir may be attached. This tack receptacle or Serial No. 629,718. (No model.)

' entire length adjacent to the outer side of said chamber, and a suitable carrier D, having in its top a deep slot d, is fitted to said opening 0 and permitted a limited vertical movement therein by means of a screw (1, which passes through one end of a lever D and the opeuing 0 of the feed-chamber C and is threaded to the lower part of said carrier D, the opposite end of said lever D being rigidly mounted at one end of a shaft E, carried in bearings e 6, provided upon the tack-race, to be hereinafter explained, the opposite end of said shaft being fitted with a crank 6, connected with a trigger or lever F (held normally in the position shown by a suitable spring f) by the connecting-rod f, as seen in Figs. 1, 5, and 6.

The normal position of the carrier D is best shown in Fig. 4-4. 6., when the top in which the slot d is formed shall be flush with or slightly below the bottom of the feed-chamber 0. Hence some of the tacks which enter said feed-chamber through the opening 0 fall into the slot of said carrier with their heads resting upon the top thereof.

In the drawings the lever or trigger F is shown in its normal position, and the movement of the parts just described is one of the functions of said lever, and by moving said lever (referring to Fig. 1) to the left the carrier rises to a point opposite the openings 0 formed in the end walls of the feed-chamber, (one of which openings is shown in Fig. 4,) and by tipping the hammer in either direc tion, as would naturally follow its use, the tacks in said carrier chase each other out through either of said openings 0 into either of the spirally inclined tack races G G, whence said tacks unite in the horizontal curved race H, leading to the striking mechanism soon to be described, the opening h,

ing through said raceways, as shown atg g h, i

and to guard against clogging a spring-actuated feed-dog I (shown best in Figs. 2 and 5) is pivotally attached to one end of a lever t', the opposite end of which is secured to an ear g attached to or form ed upon the race G,

as best shown in Figs. 1 and 2, and secured to said lever i is an arm 2', the free end of which is provided with a lateral projection 2' which engages the lever F at a certain point in its stroke, whereby the lever 'L is moved upward and backward, thus disengaging the feed-dog I from the tacks in the raceway H, 1 so that when said dog again drops to its nor- 1 .mal position it will engage tacks back of those which it had just left, and so the movement orlev-er F, the spring 2' serving two purposesviz., to insure contact with the tacks and to draw the tacks in the raceway H forward and thus keep them moving toward the tacksticking mechanism at the end of said raceway H.

In Figs. 2 and 3 I show this tack-driving The raceway I-I. termi- 1 mechanism in detail.

nates at one side of a vertical case or tube J, which contains the tack-driver K, the upper 1 end of which is connected to a spring-arm is, serving to normally hold it down within its case or tube, which has a vertical opening j in its side at the proper point to connect with and receive tacks from said raceway H. Opposite this openingj in said tube J are provided a tack-separator L and a feed-bar M, both working at right angles to the raceway H, the separator being ahead of the feed-bar, as shown.

.3 represents the tacks, several .of which are shown by dotted lines in Fig. 3, and in Fig. 2 one tack is shown in solid black, the separator L having moved outward, separating this particular tack from the others and placing it directly in front of the feed-bar M, which will now move sufficiently to push said tack through the opening j of the case or tube J and under the spring-actuated tack-driver K, which immediately snaps down upon said tack with enough force to leave it standing ready to be struck by the hammer A.

The upper end of the trigger or lever F is rigidly secured to a shaft f, carrying at its opposite end a crank O, which is connected by the bar 19 to the lower end of a rocker or lever P, hung'on a pin or screw 19', the upper end of said lever P engaging a bell-crank Q, by which the spring-arm 7a is raised, as shown best in Fig, 5. The lever P is also connected to the bell-crank R by the connecting-bar T. This bell-crank R operates the separator L and feed-bar M, one before the other, as

shown best in Fig. 5, one end of the crank bearingagainst the separator, while a projection r, formed upon one side of said crank and near the end'which contacts with the separator,en gages the feed-bar M, said projection r being located the proper distance from the end of said bell-crank to cause the separator to move before the feed-bar. The tack-driver K rises just before the feed-bar M pushes a tack under it, when'it snaps down upon the tack, the operation being repeat-ed with each movement of the trigger or lever F.

It is advisable to provide some means to prevent the tacks in the raceway II from moving in a direction away from the tack-stick- 1 from the raceway H to the tube J and to recontinues with each movement of the trigger .1

turn them to their normal position directly after being moved by the bell-crank R and its projection r.

Having described my invention, what I claim is- 1. Ina device of the character described,

; asuitable receptacle for tacks, raceways leading from each end of said receptacle to a point of union,one with the other,and means where by said tacks may be dropped consecutively with their heads up and then struck, substantially as set forth.

2. The combination with a tack-receptacle, of .a tube, a raceway leading from the receptacle to the tube, a carrier within the receptacle, means for feeding the tacks singly to the tube, a spring-actuated spindle within the tube, and means for simultaneously op- .erating the feeding mechanism, moving the spindle against the spring, and operating the carrier, substantially as set forth.

3. Thecombination with a tack-receptacle, of a tube, a spring-actuated spindle therein, a raceway leading from the receptacle to the tube, a separator and a feeding-bar for feeding the tacks singly to the tube, a feedingdog for feeding the tacks along the raceway, and means for simultaneously moving the spindle against the spring and for operating the separator, the feeding-bar, and the feeding-dog, substantially as set forth.
