DRIVER OR DRAWER FOR DRAFTSMENS TACKS.

SPECIFICATION forming part of Letters Patent No. 590,760, dated September 28, 1897. Application filed January 21,1897. $erial N 620,t)61. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES F. HEATH, a citizen of the United States, residing at Rutland, Rutland county, Vermont, haveinvented an Improved Driver or Drawer for Draftsmens Tacks, of which the-following is a specification.

This invention relates to improvements in devices or tools for pressing in and drawing out the broad-headed tacks employed by draftsmen to fasten down their paper; and the object is to provide a simple and inexpensive tool especially adapted for the purpose intended. 7

In the drawings, which illustrate two embodiments of the invention, Figure 1 is a perspective "iew of one form of the device. Fig. 2 is a front end view of the same. Fig. 3 is a side view of the same, and Fig. 4 is an under side view of the same. Fig. 5 is a side view, and Fig. 6 a front end view, of the device in a form slightly different from that in the other figures. Fig. 7 comprises three illustrative views showing the manner of using the tool.

Referring to the first four figures of the drawings, which illustrate the invention in its simpler embodiment, thetool is formed of a single strip of flat metal bent into a loop-like shape or contour. The arch of the loop forms a handle a and the lower part of theloop forms a convex or rocker base'b. The pro: jecting extremity c of the base is brought to' an edge or sharpened and has in it a slit (1, Fig. 4, to receive the body of the tack 00, Figs. 2 and 7, in setting and drawingthe latter. The other extremity e of the strip of metal over the slit d is bent back parallel with the slitted end and then shouldered down upon the baseat f, where it is secured to the latter. The shoulder at f forms a pocket g, Figs. 2 and 3, between the flat slitted extremity c and portion a above it, to receive the broad head of the tack 0c, the part c forming a roofplate for the said pocket. 7

The advantages of the tool will-be apparent to any draftsman, and the operation of setting and driving the tack will be readily understood from the illustrative View, Fig. 7. The tack a; is placed in the tool with its body engaging the slit (1 and its head engagin g the pocket g. The draftsman grasps the handle a and places the convex base I) on the paper substantially as in the upper view, Fig. 7. He then rocks the tool forward, rolling the creases from the paper and stretching it properly to receive the tack. The middle View in Fig. 7 shows the tack set in the paper and board by the tool, and the lowermost view in said Fig. 7 shows the mode of driving the tack home after the tool is withdrawn from it. To draw out the tack, the sharpened and slitted end a is passed under the head of the tack in such a manner that the body of the latter passes into the slit d, and the tool is then rocked on its convex base in such a in which the loop-like handle is of cast metal,

and there are two tack drawing and setting devices, one at each end, the-slits being formed in a separate plate of metal which forms the rocker-like base I) and which is secured to the cast metal above it. This form provides a heavier and stronger tool than the one first described, but a more expensive one. The two drawing devices may be adapted for different sizes of tacks, if desired.

' Having thus described my invention, I would say that I do not broadly claim a tool or device for drawing out draftsmens tacks and having a sharpened extremity and a notch to'engage the body of the same' Such devices are common, as are also devices of a similar kind for drawing out carpet-tacks; nor do I claim a tool for drawing out draftsmens tacks having a fiat surface to rest on the paper and a sharp elbow or bend for a fulcrum; but

What I do claim is-- 1. As an improved article of manufacture, a tack driving and drawing tool having a convex base and a sharpened and slitted extremity, and a loop-like handle which extends in the form of a loop from the slitted extremity to the opposite end whereby pressure may be applied directly over the tack for driving it, substantially as set forth.

2. As an improved article of manufacture, a tack driving and drawing tool, having a convex, rocker-like base, one end of which is sharpened and slitted as described, and a loop-like handle, a part of which extends over said slit and forms the roof-plate of a pocket pocket g, to receive the tack-head, substan- K) which receives the head of the taclgsnbstam tially as set forth. tially as set forth.
