T; VAivLAN- United States, residthe county of Adair following is a specification.

This invention relatesto magazine hatch- 'ets, hammers, and similar tools, and has-for its objectto provide an inexpensive and efh- '-cient tool of this? character in which the nails or-tacks are automatically f d from the magaaine-to thedriving-head of thetool, so that the 'n'ails may be successively positioned and driven without the necessity of handling the 'same.

' A further object of the invention is to provide means for guiding the nails in their passage from the magazine to the dischargechute and means for presenting the point of one nail to the work when the succeeding nail has been driven.

A still further object of the invention is to generally improve this class of devices so as 'to increase their utility, durability, and efficiency, as well as to reduce the cost of manutacture. I

-, With-t-hese and-other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings, it being understoodthat variouschanges in form, propor-' tions, and minor details of construction may be resorted to within the scope of the ap- I pended claims.

. In the accompanyingdrawings, forming a part of this specification, Figural is a side elevation of a portion of amagaz'ine-hatchet constructed in accordance with my inven tion. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view taken on the line 3 3 of l ig. 1. Fig. 4 is v a transverse sectional view of the feed trough or chute.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The sclffeeding attachment is shown in c nnection ith a hatchet, in which 5 designates thedriving-head, 6 the blade, and 7 the handle, the latter being preferably formed hollow and provided with a removable screw-cap 8, which normally closes an opening 9, through which the nails or tacks may be introduceu into the magazine 10 Secured t0 the driving-head and handle, respectively, is an inclined discharge chute or trough 11, preferably U-shaped in cross-section, as shown, and provided with laterallyproje'cting flanges 12,- through which extend screws or similar fastening devices 13 for securing the chute in position.

i The chute 'or trough 11 communicates with the magazine 10, and the adj acent. longitudinal edges of said trough are provided with laterally-extending flanges 14, spaced apart to form a guide 15 for the points of the the driving-head of thetool. Spaced from the open end of-the trough 11 and se'cured'in any suitable manner to the .handle 7 are parallel arms 17, terminating in spring lips or cars 18, adapted to support and guide the heads of the nails, and disposed above said arms and fastened in any suitable manner to the handle of the tool is a triangular-shaped block 19, designed to prevent accidental displacement of said nails.

The head proper of the tool is provided with a projection or deflecting-cam 20, w ich extends between the parallel arms 17 at the juncture of the latter. with-the handle 7, so that should the heads of the nails be presented through the openings 21 in their passage to the trough said heads. will engage the cam 20 and thus cause the points of the nails to enter the trough, and in wizich position the heads of the nails are free to pass beneath the cam and engage the arnis.l7. Should nail 16 in their passage from the magazine to obviousthat the points of the nails will enter the opening 21 and perrrit the heads of the same -to clear the cam in the manner before stated. Secured to the lateral flanges 14 of the feed-trough are spiing retaining-fingers 22, adapted to engage the heads of the nails as the latter are successively presented to the work and hold each nail with its head spaced from an anvil 23 and with its paint projecting through an, opening 24 111 the trough, as

best shown in Fig. 2 of the drawings;

Slidably mounted on the head of the tool is a spring-actuated nail-carrier 25, having one end thereof bifurcated to form a nail-receivlng recess 26, defining a pairof spaced tripping-arn .s 27, wiiich projectthrough correspondingly-shaped openings 28, forrred in the ad acent end of the feed-trough 11, the

opposite end of the nail-carrier being provided with a reduced extension 29,-adapted to enter a gulding recess 30, there being a coiledspringfil interposed between. the shoulders 32 or tile carrier andthe block 19 for normally holding the trip-mars extended beyond the active face of tie drivinghea 'l.

As a means for limiting the longitudinal movement of the nail-carrier the latter is rovided witha )in or ro'eetion 32 ads ted to engage the Walls of a slot or opening 33, formed in the head of the tool, as shown. It will thus be seen that when the first nail has been driven or partially driven into the work the trip-arms 27 by engage: .ent with 'said work will depress the nzil-carrir-zr and move the latter longitudinally against the tension of the spring 31. until the nail-receiw ing recess 26 registers with the adjacent nzzil carried by the spring-lips 18, thus porn it'ting the nail to drop into-the recess, so the t when the tool is elevated above the work said nail Wlll' drop by gravity into engagentrnt with the spring-fingers 22 and be supported in position against the anvil 23. As soon a pressure on rat trip-arms is released by elc vating the tool above the work thespiing will automatically return the carrier to nor mal or inoperative position over the springlips 18, thus locking the'nails in (-ngagenient with the parallel arms 17 until the carrier is again reciprocatcd Attention is called to the fact that the block 19 not only serves as a means for preventing accidental displacementof the nails, but also serves as a means for guiding the carrier. It will thus be seen that the nails are automatically fed to the dliving-ltead oi the tool Without the necessi'ty'oi handling h e same, While, by reason of the slotted-nail-cafrier, but a single 'nail will be presented to the work at a time.

While the automatic feeding device is shown'in connection with a hatchet, it i cb vi-ous that the same may be used on a hanv mer or any other tool in which a device of this kind is found desirable.

Havi thus described the invention, what is claims is 1. In a device of the class described, a tool having a driving-head and provided with a hollow handle constituting a nail-receiving me azine, a discharge-chute communicating with the magazine; guidearms disposed above the chute and provided with terminal spring-lips, an anvil carried by the driving head, sprin fingers secured to the dischargechuteand isposed at said anvil for engagement with the nails, and a sliding naihcarrier having a recess formed therein and adapted to successively receive the nails and d the same to the spring-fingers.

2. In a device of the class described, a driving-head provided with a nail-receiving magazine, a discharge-chute communicatin with. the magazine, guiding-arms dispose above the disch arge-chute and provided with carrier and operating within a slot in the tool forlimiting the sliding movement of said nail-carrier, and spring-fingers secured to the chute for supporting the nails at said anv1l. 4. In a device of the class described, a tool having adriving-head and provided with a,

hollow handle constituting a nail-receiving magazine, an anvil carried by the drivinghead, a substantially Ushapeddischargechute communicating with the magazine and having a nail-delivery opening formed in one end thereof, guide-arms spaced from the discharge-chute and provided with terminal lips the free ends of which are concaved, a spring-actuated nail-carrier having one end thereof bifurcated to form a nail-receiving recess and provided with terminal trip airms I extending through openings in the di'scharge-' chute, a spring interposed between the mailcarrier in the adjacent wall of the tool, and means for limiting the sliding movement of said nail-carrier.

5, In a device of the class described, a tool having a driving-head and provided with a hollow handle constituting a nail-receiving magazine, a dischargc chute communicating with the magazine, an auxiliary chute s aced from the discharge-chute and provide with terminal spring portions adapted to support I the heads of the nails, a substantially triangular-shaped block secured to the handle and arranged adjacent the auxiliary chute, and a spring-actuated nail-carrier having a recess formed therein adapted to receive the nails and deliver the same successively to the driving-h cad.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
