SETTING-TOOL FOR BRAIDS, 86C.

To all whom t may concern Be it known that we, THOMAS M. PRICE and WILLIAM A. TYNEs, citizens of the United States, residing at Cooper, in the county of Delta and State of Texas, have invented a new and useful Setting-Tool for Brads, &c., of which the following is a specification.

This invention relates to improvements in setting tools for brads, pins and the like, and has for its object to provide a simple, cheap and effective tool to be held in the hand which will serve to place a brad at exactly the desired point, and which may be operated by an unskilled person with ease and rapidity.

In the accompanying drawing F igure 1 is a side elevation of a hammer with the setting appliance mounted in the handle thereof. Fig. 2 is aside elevation of a hand tool embodying` the preferred form of our invention. Fig. 3 is a longitudinal sectional view taken through Fig. 2. Figs. 4 and 5 are cross sections taken on the lines 4 4, 5 5 of Fig. 3.

Referring first to Figs. 2 and 3 of the drawing, which illustrate the preferred embodiment of the invention, 5 designates the handle, which is preferably made of wood and tapered from its inner to its outer end. The upper or inner end of the handle is rounded to make a convenient support for the palm of the hand, and intermediate its ends the handle is formed with an annular rib 6 which is furnished with concave sides merging into the sides of the handle. The rib serves as a rest for the ends of the ngers, and it is flattened at 7 toform a rest to prevent the tool from rolling off a table upon which it may be placed, and also to permit the tool to fit flat against an object while driving a brad. The handle is provided with a socket or bore 8, circular in cross section, which extends from its outer or lower end to a point near its upper end. Adapted to be removably mounted in the socket 8, but fitting vclosely therein, is a metal sleeve 9. The lower or outer end of the sleeve is slightly enlarged to form an exteriorly screw threaded collar 10,'

which projects beyond the lower or outer end of the handle. In the inner or upper end of the iixed sleeve 9 and closing the same is positioned a short tube 11, the upper or outer end of which is interiorly Specification of Letters Patent.

threaded to receive a screw 24, which passes through a hole in the upper or inner end of the handle and has its head countersunk iiush with the handle. In the other end of the tube is seated the inner end of a round plunger or rod 12, saidrod being'securely fastened in position by a rivet 13 which extends diametrically through the fixed sleeve 9, the tube 11 and the end of the plunger 12 thus locking them against relative movement. From its inner or upper end to a point about opposite the lower or outer end of the iixed sleeve the plunger is of uniform diameter, but at this point it is shouldered at 13a and reduced in diameter to form a section 14 which continues to the outer or lower end. This reduced section of the plunger has a diameter slightly larger than the diameter of a brad and is provided at its extremity with a depression designed to receive the head of a brad or other fastener to be driven. Adapted to be removably inserted in the lixed sleeve 9 is a coiled spring 15, which fits closely therein, its inner or upper end resting against the lower or outer end of the tube 11. Slidably mounted on the plunger 12 is a movable sleeve 16, the inner or upper end of which is provided with an annular flange 17 against which the outer or lower end of the coiled spring 15 bears. The movable sleeve at a point intermediate its ends is provided with another annular flange 18, which, in the normal position of the parts, extends some distance beyond the lower or outer end of the fixed sleeve 9. The movable sleeve is held in position by a cap 19, which is interiorly screw threaded at its inner or upper end to screw onto the threaded collar 10 of the fixed sleeve. The interior diameter of the cap is slightly larger than that of the slidable sleeve 16, but at its outer or lower end it is formed with an inwardly extending annular flange 20, against the inner or upper side of which abuts the outer or lower face of the flange 18 of the slidable sleeve. The slidable sleeve has iixed in its outer or lower end a tubular guide 22 of less diameter, with a bore of suiiicient size to slidably receive the reduced section 14 of the plunger, and said iixed guide extends up the movable sleeve and its inner or upper end forms an abutment for the shoulder 13a of the plunger. Since the slidable sleeve 16 and the fixed guide 22 are held against relative movement, they constitute in eect a single movable part. The extreme outer or lower end of the reduced part or guide 22 of the slidable sleeve 16 is provided with a beveled side 26, the purpose of which is to allow a workman to place and set a brad or other small driven fastener very close up to the edge of the work, as for instance when fastening brads in picture frames or fastening points in sash frames. y

In Fig. 1 we have shown the setting appliance mounted in the handle of a hammer. This is accomplished without any change of structure over that shown in Figs. 2 and 3, except that instead of having the rivet 13 passing through the fixed sleeve 9, the tube 11 and the plunger 12, a screw 27 is used, which passes through the handle of the hammer as well as through the fixed sleeve 9, the tube 11 and the plunger. In this .form the screw 24 is dispensed with.

From the foregoing it will be apparent that we have pro-duced an exceedingly handy and useful tool with which a brad or like fastener can be accurately driven in places where it would be inconvenient to use a hammer.

It will be noted that the fixed sleeve 9 carries all the parts except the handle, and thus when the end screw 24 of the form shown in Figs. 2 and .3, or the side screw 27 of Fig. 1 is removed, the fixed sleeve 9 carrying all the parts can be withdrawn from the handle of the tool.

With the parts in the position shown in Fig. 3, a brad is placed in the bore of the reduced end portion or Vfixed guide 22 of the slidable sleeve 16, with its head abutting against the end of the reduced sectio-n 14 of the plunger 12. The end of the reduced portion 22 of the slidable sleeve is placed against the part into which the brad is to be driven, and by pressing down upon or against the end of the handle 5, the brad will vbe firmly set in position.

It will be noted that the travel of the movable sleeve within the fixed sleeve 9 is limited by the inner or upper end of the fixed guide 22 contacting with the shoulder 13a, and when such contact takes place, the lower end or outer extremity of the reduced section 14 of the plunger is caused to project beyond the lower or outer end of the guide 22. The outward movement of the movable sleeve 16 is limited by its flange 18 coming in contact with the flange 20 of the cap 19.

It will be understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
