NAIL OR TACK DRIVING IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 579,880, dated March 30, 1897. Application filed J'uly 3, 1895. Serial No. 554.815. (No model.)

To all whom it may concern.- Y

Beit known that I, THoMAs JUDsoN LANG- STON, a citizen of the United States, residing at Johnston, in the county of Edgefleld and State of South Carolina, have invented a new and useful Implement for Driving Nails or Tacks, of which the following is a specification.

My invention relates to a machine or implement for facilitating the driving of nails and tacks by hand.

The object of my invention is to provide an improved machine, easily and conveniently carried in the hand, in which nails or tacks may be put and automatically arranged and fed to the driving` mechanism one at a time.

My invention consists in details, arrangement of details, and general construction of implement to drive nails and tacks.

In the drawings, Figure 1 is a broken front elevation of my nailing and tacking implement. Fig. 2 isabroken side elevation. Fig. 3 is a sectional broken view taken from the same point of observation as Fig. 2. Fig. 4. is an inside perspective view of one side of driving end or head, showing the interior mechanism in position, the opposite side being removed. Figs. 5 and .6 are perspective views of the rings and wings that hold arranging chute and plate D in position, also forming a part of the hopper. Figs. 7 and 8 are plan views of opposite sides of the ring that holds the lower and upper ends of arranging and conveying chutes. Dotted lines in Fig. 7 show how the arranging-chute E fits into the ring I. Fig.- 9 is a cross-section through the hopper on dotted line 2 2, Fig. 2. Fig. 10 is a back view of feed-bar, arrester, and feeder attached. Fig. 11 is a perspective view of arrester and feeder detached from feed-bar. Fig. 12 is a sectional view of arrester and feeder on dotted line in Fig. 10. Fig. 13 is a perspective view of an attachment to prevent tacks reversing after entering driving-rod way Fig. 14 is a detail side view in elevation of lower end of arranging-chute. Fig.

15 is a perspective view of safety-tongue. Fig. 16 is a perspective view in detail of the pieces that arrest, center, and hold the nail or tack while being driven.

A is a handle, preferably made of wood, in

halves held together by cap b, rings G II I, and driving-head O, each half half-round grooved out inside, forming when the halves are together a round bore of proper size to receive the driving-rod B. This bore is enlarged in suitable places to receive bearings c and d, as shown in Fig. 3. An opening is made in the lower end to receive and allow the feedbar K free room. The outside of handle A should have a groove to receive the chute E and also a chamfer between hopper-wings G and H, allowing suliicient room for nails or tacks to enter freely. (Shown in Fig. 9.) At fthe tqp end of handle A is surmounted by cap b, seat c, and cushion CZ. Cap b has a liange on its top edge or end, seat c a iiange on its bottom edge or end, the two flanges combining to confine seat c in place and cushion d between seat c, and handle A should be of suitable material to prevent bruising the top by blows on seat c. Cushion d is also conlined between cap h and bearing c, bearing c having a flange on its lower edge or end to hold it in place.

B is a plunger-rod, with handle B', drivingpoint a, and set-nut B2. The driving-point ct is threaded a sufficient portion of its length to screw into the plunger-rod and be secured at any length desired by set-nut B2. Handle B is preferably cast on theplunger-rod, which is adapted to move freely in handle A and driving-point a through the chamber in the barrel of driving-head C.

D is a plate forming a trough or hopper and held in position by being secured to wings G and H, projecting from and attached to or forming a part of rings that are secured to handle A. 'Ihe inner edge of the plate D is held in due position with a chute by a double or folded strip i, fastened to the plate D. (Shown in Fig. 9.)

s is a recess in a laterally-projecting portion of ring G that chute E fits into, with lug r through the slit or nail-path, thereby securing the upper end of chute E to and preventing its turning on handle A.

I is a ring that secures the lower end of chute E and upper end of chute F to the handle A, the chutes projecting into recessest and u.

z represents points on the end of chute E,

IOO

projecting into chute F to secure an easy passage of nails or tacks from chute E to chute F.

Chute E has an opening fr in one side (shown in Figs. 3 and 9) to receive the nails or tacks from hopper D. Chute F receives the nails or tacks from chute E, conveying them to head C, with the heads inside and shanks extending through the slit of the chute. Near its lower end the chute F is cut away at 011e side, Figs. l and 3, to form an opening, which is closed by the free portion of a plate-spring 7L. The latter allows a crooked or misshapen nail or tack to be removed.

c and c' (shown in Fig. 3) are bearings, e for rod A, the same having a [lange on its lower end or edge to hold it in place.

C is a head or driving end, preferably made in two parts held together by screws. lts interior mechanism is shown in Fig. 4lwith tack attachment Nin position. This device merely prevents the possibility of tacks reversing. It is (see Fig. 4) a bentplate-spring having its outer end in contact with alateral proj ection and its straight inner side arranged at a slight angle to the nail-pathway.

At w a chamber or recess is formed to receive the lower end of chute F, from which nails or tacks enter to driving'point way between the `i11iitle\'vi1igs. projecting from the barrel C'. These wings are connected with the rim of head C by the walls of the recess or chamber it' and have corresponding curved spaces between their upper edges and corresponding spokes or arms connecting the barrel and rim oi' head C. Said spaces constitute the path for nails or tacks and enlarge at I', reduce at in, and enlarge again in entrance to the chamber of barrel.

At ai, Fig. et, wings or jaws project inward to or nearly to the plunger-way. lctwcen these jaws 'feed-bar K is pivoted.

y and y are guide-jaws projecting out from the barrel, connecting with the rim er band which fits closely around handle A. rlhese jaws guide feedsbar K accurately in its work. Other arms or spokes also connect; rim and barrel of head C, insuring rigid and accurate alinement with driving-point (t. The upper end of barrel C' projects into the bore of handle A.

M is a spring-controlled half-reu nd grooved tongue (shown in Figs. 3, Li, and l5) fulcrumed on one of the screws that 'fasten the two parts of head G together. This tongue has a back swell at n to allow heads of nails or tacks to pass feed-win g 3, which projects from arrester J into the path of drivingpoint a. Spring g holds tongue M in position, and should more than one nail or tack be in the path of drivingpoint a at one time the tongue M will swing back and enlarge the passage, thereby preventing wedging and injury to the machine.

K is a spring-controlled feed-bar pivoted between the jaws 0c, (and guided in operatin g by guide-jaws y andy) with feed and arrester J attached. The elbow at l projects into the bore of barrel C', and the shoulder at 2 projects into the bore of handle A. The feedbar is shown in its normal or closed position by dotted lines in Fig. l.

ln operating the drivin g-point a strikes the elbow at l, moving the feeder and arrester J back sufficient to allow the drivin g-point (L to pass the feed-wing Then the plunger or set-nut on plunger-rod strikes shoulder 2, moving the feeder and arrester .T back enti rel y from the nail or tack way, which allows the innermost nail or tack to move in against the driving-point. In withdrawing the rod when the set-nut passes the shoulder 2 on feed-bar K the point of feed and arrester will enter the nail or tack way just outside of the innermost nail or tack. On the i'urther withdrawal of driving-red this nail or tack will be forced by feed-wing into the chamber of barrel C and fall into position for driving. J, the feeder and arrester, is attached to the eed-bar l( by screws passing through holes larger than the body oi' the screws, which permits adjusting. l on bar K, projecting into the chamber of barrel C, makes it possible to drive overhead.

L and L are sprin gs the lower ends of which, when brought together in position, form a funnel, centering and insuring the nail or tack being driven centrally.

N is a spring attachment which is inserted, as shown in Fig. et, when tacks are to be driven, which prevents them reversing.

To iill, hold the implement in an inclined position with the driving end lowest and the chutes underneath. This brings the hopper in position to receive nails or tacks, which must be sprinkled into it. In and after entering chute E the shanks of nails or tacks will fall through the slit or space Lt, (shown. in Figs. l and 9,) hanging with thehcads inside the chute, passing in this position into chute F and head C against arrester J. In driving, the chutes are to the front and upl'iermost.
