CONVERTIBLE APPARATUS.

SPECIFICATION forming part of LetterslPatent No. 653,317, dated July 10, 19O0I. Application inea January 10,1000. serial No. 1,010. (No man.)

To a/ZZ whom it may concern:

Be it known that I, CHRISTIAN A. SALZMAN, a citizen of the United States, and a resident of Hamilton, Chio, haveinvented certain new and useful Improvements in Convertible Apparatus, of which the following is a specification.

Myinvention relates to convertible apparatus adapted to the use of farmers, mechanics, or others in making or repairing articles of metal, leather, or wood; and the object of my improvement is to provide a frame the structure of which admits of its being used separately in connection with a variety of tools, so that by a simple change of tools a machine of one kind may be converted into that of another kind, such as a drill-press into a vise or apipe-vise or a grinding-machine or a sawclamp. This object is attained in the following-described manner, as illustrated in the accompanying drawings, in which- Figure lis a side elevation of my improved tool; Fig. 2, a side elevation,with parts in section, of portions showing the vise, pipe-vise,

and drill-press; lFig. 3, a side elevation,with

parts in section, showing the position of the saw-clamp in the vise; Fig. 4, a front elevation of the movable vise-jaw; Fig. 5, 4a rear elevation of the anvil, and Fig. 6 a front elevation of the saw-clamp.

In the drawings, 11 represents the base, preferably of wood, whereon track 12, T- shaped in cross-section, is secured by bolts 13. Threaded boss 14 is raised above the rear end of the track, and lug 15 above the front end thereof. Anvil 16 is formed with horn 17 and heel 13, that also serves fo'r the 4stationary vise-jaw. Abutment 19 projects from the rear end of the anvil flush with its heel and contains hole 21 and mortise 22, as shown in Figs. 2, 3, and 5. Flanges 23 project from the sides of the anvil to Widen its base and for the passage of bolts 24 therethrough to secure it to the base. Notch 25 is formed underneath the rear portion of the anvil to engage lug 15 on the track and lock it securely thereto.

Movable vise-jaw 26 is formed with flanges 27 turned inwardly on its bottom to slidin-gl y engage with the track. Its face 28 projects forwardly to register with the face of the heel of the anvil, and both faces are milled or roughened to hold an article more securely when clamped between them. Drill-spindle 29, provided with toothed pinion 31 on its rear end and with a drill chuck or socket 32 on its front end, is journaled in the top portion of vise-jaw 26. Bracket-spindle 33 is removably secured by thumb-screw 34 on the top of said vise-jaw. Internal gear 35, provided with handle 36, is mounted on said `loracket and engages pinion 31.

Vise-screw 3,8, journaled in jaw 26 and threaded in boss 14 on the track, is actuated by hand-wheel 39, secured on its rear end to move said jaw `more or less toward the anvil. Auxiliary hand-wheel 41,secu red on the front end of said screw,is convenient for the operator to feed the drill while his right hand is engaged with handle 36 to rotate gear 35, that drives the drill secured in chuck 31 in the same direction and at more rapid speed.

Grindstone 43, secured on shaft 44, is removably mounted between the jaws of the vise by journaling one end of the shaft in circular hole 21 in the anvil-abutment and securing the other end thereof in drill socket or chuck 31 that it may be driven in thesame manner as the drill that is displaced thereby.

Saw-clamp 45 consists of two arms hinged -together and formed with transverse clamping-blades that register with each other, as shownin Figs. 3 and 6. Flange 46 and pin 47 project from one of said arms to removably fasten the clamp on the anvil by placing the flange on its heel and inserting the pin in hole 21 therein. The other arm of the clamp isv actuated by movable jaw 26 of the vise to properly clamp a saw for ling, leather for sewing, or other article.

Pipe- vise jaws 48 and 49 are formed with similar V- shaped toothed notches in their faces, and they are removably secured, by means of screws 51, to the lower portion of movable vise-jaw 26 and in a manner. to project from Opposite sides of recess 52, formed in its face. The opposite jaw 53 of the 4pipevise is formed with a V-,shaped toothed notch in its face to resemble jaws 48 and49 "and with tenon 54 on its rear end to removably fit in mortise 22, formed in the anvil-abutment 19. By the movement of vise-jaw 26 jaws 48 and 49 thereon are carried closelyalong opposite sides of stationary jaw 53 to securely IOO l 65am? what I claim as my invention, and desire tol secure by Letters Patent of the United States,

1. The combination with a T-shaped track formed with a boss on one end, an anvil at.

tached to the other end thereof, a vertical jaw movably engaging with the track, and formed Withva lateral face adapted to engage With the heel-of the anvil, and a hand-screw threaded inthe bossand swiveled in'the jaw, of a drillspindle jou'rnaled in the jaw, a pinion secured thereon,and a gear-wheel removably mounted zo on the jaw and engaging with the pinion.

2. The combination with a T- shaped track formed with a boss on one end and a hook on the other end, an anvil formed with a notch adapted to engage with the hook, a ja'W mov-V ably engaging with the track and formed With a laterally-projecting face adapted to engage with the heel of the anvil, a hand screw threaded in the boss and swiveled in the jaw, and a hand-Wheel secured on each end of the screw, of a drill-spindle journaled in the jaw, a pinion thereon, and an internal gear-Wheel removably mounted on the jaw, and arranged to engage with the pinion.
