LELAND GRANT YOUNG, OF MUSCATINE, IOWA.

HAMMER.

SPECIFICATION forming part of Letters Patent No. 602,971, dated April 26, 1898.

Application filed August 6, 1896.

T0 and whom it may concern:

Be it known that I, LELAND GRANT YOUNG, a citizen of the United States, residing atMuscatine, in the county of Muscatine and State of Iowa, have invented a new and useful Hammer, of which the following is a specification.

The invention relates to improvements in hammers.

The object of the present invention is to improve the construction of hammers and to provide a simple and inexpensive one which will carry a supply of tacks and which will automatically feed a tack in position to be struck by the hammer-head.

A further object of the invention is to provide a supplemental or auxiliary head for t-acks' to increase their holding power and to facilitate the tacking of cards at an elevation without the use of a step-ladder or other support by providing means for holding a card on the hammer in position to receive a tack.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a hammer constructed in accordance with this invention. Fig. 2 is a longitudinal sectional View of the same, the hammer being thrown forward. Fig. 3 is a transverse sectional View. Fig. 4 is a longitudinal sectional view on line 4 4 of Fig. 2. Fig. 5 is a detail perspective view illustrating the arrangement of the resilient pawls and showing the pawl of the feed-bar in position for advancing the tack-carrying strip.

Like numerals of reference designate corresponding parts in all the figures ofthe drawings.

1 designates a tubular stem forming a tackholder or magazine and provided at its inner end with asocket 2 for the reception of a handle 3, which may be of any desired length to give the hammer sufficient reach to enable a placard, bill, or the like to be tacked at the desired elevation. The stem or tack-holderis substantially semicylindrical and is provided at its straight or flat side with a central longitudinal groove 4 to receive the shanks of tacks 5, and it is provided at opposite sides with flanges 6, extending from the flat side or back of the tubu- $erial No. 601,881. (No model.)

lar stem or tack-holder and forming a way for the reciprocating feed-bar 7, which is adapted to advance the tacks successively to a point just beyond the outer end of the tack-holder in position for them to be struck by an oscillating hammer-head 8. The hammer-head S, which is located at the outer end of the tackholder or magazine and which is arranged to move transversely thereof, is fixed to an oscillating arm or bar 9, which is hinged at its inner end to the tubular stem or tack-holder adjacent to the inner end thereof, the tubular stem or tack-holder being provided with perforated cars 10 for the reception of a pivot, which also passes through theinner end of the arm or bar 9. The arm or bar 9 is supported by a substantially rectangular keeperll, disposed transversely and extending from the tubular stem or tack-holder near the outer end thereof. The hammer-head is held raised in position for driving a tack by a spring 12, interposed between the arm or bar 9 and the tubular stem or tack-holder and preferably secured to the former; but it will be apparent that it may be attached to either of the said parts.

When a tack is fed from the tack-holder or magazine to a position in advance of the outer end of the same, the entire device is swung similar to an ordinary hammer in striking a blow. The outer end of the hollow stem or tack-holder comes in contact with the surface into which the tack is to be driven; but the hammer continues its movement after the tubular stem or tack-holder has come in contact with the said surface, striking a tack and driving it into such surface. If the force of the blowshould not be sufficient to drive the tack completely into such surface, the reverse side of the hammer-head may be employed to complete the tacking operation.

The tacks are mounted on a strip 13, of paper or other suitable material, which is inserted in the tubular stem or tack-holder through an opening 14 at the inner end thereof, the shanks of the tacks extending into the (zen tral longitudinal groove and the strip of paper in the longitudinal way being received between the side flanges 6. This strip, which carries the tacks, is provided at opposite sides with substantially \lshaped notches 15, which fixed to the tack-holder or magazine and arranged within the way thereof, and a similar actuating-pawl 17, carried by the reciprocating feed-bar. These pawls, which are resilient and which have their forward or outer ends curved inward, as clearly illustrated in Fig. 4 of the accompanying drawings, are arranged to engage opposite sides of the strip, which is automatically fed inward by the return movement of the parts of the hammer after striking a blow in driving a tack. The reciprocating feed-bar is provided at opposite sides with perforated ears and is connected with the oscillating bar or arm 9 by a link 19, which is disposed at an angle to the tubular stem or tack-holder and the oscillating bar or arm 9 and interposed between the said parts. The link, which is substantially U-shaped, is composed of two sides, connected at one end by a transverse portion which is arranged in a perforation of the arm or bar 9, and the sides of the link at the other end thereof are bent outward and are arranged in the perforations of the ears of the feedbars. By this construction the feed-bar is reciprocated by the oscillation of the arm or bar 9 independent of the tubular stem. When the oscillating bar. or arm 9 moves forward independently of the tubular stem in striking a blow, the feed-bar is moved inward and its actuating-pawl engages a notch at the adjacent side of the strip and the return movement of the hammer carries the feed-bar outward, whereby the strip of tacks is fed forward. The resilient check-pawl engages the strip of tacks and prevents it from .moving inward with the feed-bar. The feed-bar is provided at opposite sides with flanges receiving the strip of tacks between them and fitting in longitudinal grooves located at the opposite sides of the central longitudinal groove of the tubular stem or tack-holder. The grooves and the way of the stem or tackholder are preferably formed by longitudinal strips arranged parallel to form the central longitudinal groove and having their outer longitudinal edges angularly bent and inwardly offset to form substantially L-shaped flanges, the lateral portions thereof forming the bottoms of the side grooves and connecting the strips and sides of the tubular stem below the upper edges thereof. The tubular stem or tack-holder is provided at its outer end with a back portion 20, which connects the flanges 6 and which assists in retaining the feed-barin its longitudinal way, and it is also engaged by the free end of the spring which raises the hammer-head.

The forward end of the hammer-head is arranged at a slight angle to provide a cutting edge 21, which passes over the outer end of the tubular stem or tack-holder, making a shear cut and. adapted to sever a portion of the strip 13, and the severed portion of the strip remains on the tack, forming a supplemental head to increase the holding power of the tack.

The tubular stem or tack-holderis provided at its front side with a flat spring 22, secured at its inner end and having its outer end free, whereby it forms a clip adapted to receive and support the lower edge of a card to hold the same in position for tacking it. This clip or support will enable a card to be attached to the device, and the hammer, being of considerable length, will enable the card to be tacked on a fence or other support at an ele- Vation from the ground to be out of the reach of children. At opposite sides of the tubular stem or tack-holder are arranged sockets 23, receiving rods 24, which are provided at their outer ends with hooks for supporting a bill or similar paper in position to be tacked. The rods are removable and when not in use may be taken out of the socket, so as not to interfere with the use of the hammer for any purpose.

It will be seen that the hammer is simple and comparatively inexpensive in construction, that it is automatic in operation, and that the tacks are positively fed forward simply by the movement of the hammer in strikinga blow. It will also be apparent that the strip on which the tacks are mounted f u rnishes supplemental heads for the tacks to increase their holding power.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

What I claim is 1.
