ARTHUR WILLIAM SAVAGE, OF UTICA, NEW YORK, -ASSIGNOR To. THE y MAGAINEEHAMMER.

SPECIFICATION forming part of Letters Patent No. 653,890, dated July 1f?, 1900. Application filed April 27, 1899. Seriallila. 714,680. (No model.)

To @ZZ whom t may concern.-

Be it known that I, ARTHUR WILLIAM SAV- AGE, of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Magazine Magnetic Tack-Hammers; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the letters and figures of reference marked thereon, which form part of this specification.

My present inventionl relates to improvements in magazine magnetic tack-hammers.

In the drawings, Figure l shows a side elevation of stack-hammer of my improved construction. Fig. 2 shows the same with the handle portion in longitudinal section, eX- posing to view the working parts in the handle. Fig. 3 shows a partial section of the hammer-head and a partial section of the handle and magazine with the parts in their normal or out of operative position. Fig. 4 shows the same parts with the magazine omitted in the position which they assume after having been operated. Fig. 5 shows a rear View of the hammer-head with the parts in their normal position, in connection with a cross-section of the handle and parts located in the handle. Fig. 6 shows the same as Fig. 5 with the parts Aat the limitA of movement after being operated. Fig. 7 shows an end or face view of the hammer-headand the parts adjacent to the face. Fig. 8 shows a perspective of certain of the operating parts in an intermediate position or du ring operation.

Referring to the reference letters and iigures in a more particular description, l indicates the hammer-handle, and 2 the hammer-head, mounted thereon in the usual manner. One end of the hammer-head is recessed or cut away in order to receive the horseshoe or double-pole magnet 3, which is firmly secured to the head -2 and is held out of contact therewith bya sheet of insulating material 4. The magazine consists of a slotted tube 5, which extends along a recess in the under side of the handle and is curved down to a position on the side of the magnet of the tacks are adapted to be received in the slotted tube,while the points project through the slot-and from the magazine 5. The tacks are insertedin the magazine at a and are retained in the magazin-e by a spring 7, which operates to close this end of the magazine except against the placing of the tacks. The mouth or discharge end of the magazine is at h at the side and is substantially at right angles to the axial line of the head. For receiving the tacks from the mouth b of the magazine andmovingthem onto the face of the hammer or magnet 3 there is provided a reciprocating feeder-slide 8. The slide 8 is provided with a recess 9, the important part of which, however, is the shoulder 10 on the upper side.A The recess 9 is adapted when the slide 8 is in. its `upper position to take a position at the month b of the magazine. The slide 8 is operated by a lever 11., pivoted at l2 in a recess in the handle and having the end adjacent to the head of the hammer engaging 'in a notch in. theupper end of the slide 8. The lever ll is also provided with an angular slot 13, in which engages a stud or pin 14,- mounted on the sliding bar 15. The sliding bar 15 is provided with a finger-piece 16 and is operated on by a spring 17, located in a recess in the' handle, which spring` operates to force the bar 15 t0- ward the hammer-head. The bar 15 at4 the end adjacent to the hammer-head is provided with a catch-shoulder 18, adapted to engage under a stud or projection 19 on the upper end of the slide 8. The upper end of the slide 8 extends into the slot in the hammer-handle,` while the lower end of the slide is held 'and guided by a screw 20, passing through a slot 21 in the slide and engaging in the hammerhead. Pivoted on the screw 20 is also an automatic tack-holder 22, having a notch or re cess 22a, as shown, adapted to take a'position at the mouth b of the magazine, as shown. The automatic tack-holder 22 is operated by a projection or lip 23 on the slide 8, which engages on the cam-face'2l of the piece 22 and operates it in both directions. There is also provided a stop 25, against which the upper end Qf the piece 22 is adapted to strike, and its movement is limited in one direction there- Y 8, closeA to the face 6 of the magnet. The heads.

ICO

by. In the opposite direction the movement of the piece 22 is limited bythe lower end coming lin' contact with` the projection 3a of one pole-piece of the magnet.

The operation of the device is substantially as follows: A quantity of tacks arepla'ced in the magazine by inserting them at the opening a. WVhen the hammer-handle is brought into a substantially-vertical position with the head downward, the tacks will slide or feed toward the head, and one of them will pass out of the mouth b of the magazine into the recess 9 in the end of the slide 8 and also into the recess 22 in the end of the holder 22. Tacks will also be fed toward ythe delivery end of the magazine by the centrifugal force when using the hammer for driving. When the tacks reach the delivery end of themagazine and have come under the influence ofv the magnet, their heads follow the magnet closely. At the delivery end the tacksextend substantially at right angles with the hammer-head. When the operator desires to feed a tack onto the face of. the hammer, he

operates the feeding mechanism by pulling on the finger-piece 16. ates to throw the parts from the position vshown in Figs. 3 and 5 to the position shown in FigariL and 6. 'In this movement the shoul der 10 of the feeding device engages with the `taak close to the head and slides it down the side of the magnet, and as the shoulder 1'0 is passed beyond `the face of the magnet the head of the tack turns the angular corner between the face and side of the magnet or head, while the point'is forced over by the ad- 'vancement of the shoulder 10 until by reason of the action of the magnet on the liat head of the tack, as well as by the momentum of the point portion, the tack is brought into a line parallel with the axis of the head. In the face of oneof the poles of the magnet there is provided a shallow recess c; through which one edge of the head of the tack passes, andas the tack comes to its finalv position on the face ofithemagnet it squares'itself over both poles, for the reason that as it comes into itsl final position the magnetic influence of both poles Aofy the magnet reaches out for the tack and causes i-t to assume this position. The final position of the tack on the magnet-head is indicated by the dotted circle` in Fig. 7; Immediately after operation the parts are-returned to their normal position by the oper,- aton of the spring 17, and the tack being properly located on the face of the magnet may be driven with one or more blows, as may be found necessary.

When using the hammer for driving purposes, the tendency of the slide 8 to be projected or moved toward the face of the hammer in the direction of the blow under its own momentum is prevented bythe shoulder 18 of.the bar 15 engaging under the projection '19 on the slide 8. It Awill be noted, fur'- ther, that in the operation of the parts thehorizontal portion of theslot 13 in the part This movementoper 11.allows the shoulder 18 to becomodisew gaged from the projection 1f) before the parts- 11 and 8 begin their movement. ,The tackholder 22 when the parts are in their normal position performsthe office of entirely clos'- ing the discharge endof the magazine. Itl

would not be entirely closed otherwise, for it will be noted that one shoulder of the recess .9 in the slide 8 is much smaller than the other,

leaving an opening through which the tacks might escape if the" holder 22 were not provided.

What I`claim as new, and desire to secure by Letters Patent, is-

1. v,The combination with a hammer-head, handle and tack-magazine, of a tack-'moving mechanism consisting of the slide 8 at the side of the head having a catch shoulder or projection, the lever 11 pivoted in the handle, engaging-with the slide and having the slot 13, and the pull-bar l'having a pin engaging in said slot 13, and a shoulder engaging with said catch-shoelder,substantially as set forth.
