Application filed. March 29, 1920. Serial No. 369,507.

7 '0 all whom it may concern lie it known that l. Pnnnn O. S'rANonLAND, a citizen of the United States, residing at Los Angeles, in the count of Los Angeles, State of California, have invented new and useful Improvements in T00]. Holders, of which the following is a specification.

This invention relates to tool holders and more specifically to wood scraper holders, and the like. An object of the invention is to provide a simple, effective, and inexpensive device for holding wood scrapers, saws, etc.

A particular feature of the invention is the provision of a tool holding device which can be quickly and easily operated to grip or release a tool. This feature of the invention is important in that it makes the device convenient and simple to operate thereby making it of great commercial value. 1

An object ofthe invention is to provide a device of the character specified in which there are no bolts, catches, or like devices, that engage the tool in order to hold it. The device embodies a wedge which is adapted to be actuated by a nut to clamp the holder on, or release it from, the tool.

A further feature of the invention is the simple, compact, and neat construction of the holder. The tool holder in being compact and neat is not only sightly but is particularly convenient to handle. The holder may be easily and inexpensively constructed so that it affords a smooth and convenient grip for the hands of the operator.

There are further objects and features of the invention which will be best understood from the following detailed description of typiial embodiments of the invention throughout which reference is had to the accompanying drawings, in which- Fig. 1 is a perspective view of a form of holder particularly adapted for holding scrapers, showing the manner in which it may be conveniently gripped by the hands of an operator; Fig. 2 is an enlarged vertical central section through the device shown in Fig. 1; Fig. 3 is a perspective view of the wedge employed in the holder shown in Figs. 1 and 2, being a view of the wedge removed from the rest of the holder; and Fig. -11- is a front elevation of a portion of the holder with some of the parts broken away for sake of clearness.

In the: drawings, the invention is shown as embodied in a scraper holder. Throughout the drawings numeral 10 designates the body of the holder which is formed'with a recess or groove 11 adapted to receive the scraper 12. The body 10 of the holder is pre'li'erably formed of wood and is provided with a suitable handle 13. The bodv 10 of the scraper and also the handle 13 present smooth regular surfaces that can be conveniently and effectively gripped by an operators hand as indicated by the dotted lines in Fig.1.

The scraper 12, as shown throughout the drawings, is a flat piece of steel provided with a sharpened or properly turned edge 14:. The groove 11 in the body 10 is preferably sufficiently wide to receive the scraper 12 and suificiently deep to cause the cutting, or sharpened, edge 14-, of the scraper, to extend somewhat beyond the holder when the scraper is in place in the slot, as shown in Figs. 1, 2 and 1.

When the scraper 12 has been arranged in the groove 11, in the position desired by the operator, it can be firmly and effectively held or clamped, in that position by the movement of wedge 15 upwardly between the front side 16, of a frame or band 17. and the front side of the body 10. The band 17 is a metal member having a side 18 which engages the rear side of the body 10, a front side 16 which is engaged by the wedge 15, and ends 19 which connect the ends of sides 16 and 18 and engage the ends of the body 10, in the manner clearly shown in the drawings. The band 17, it will be noted, is arranged around the grooved portion of the body 10 so that when. the wedge 15 is moved upwardly, between the body and side 16 of band 17, it causes the grooved portion of the body 10 to firmly grip, or be clamped onto, the scraper 12 thereby positively gripping it and preventing it from becoming displaced. Due to the body 10, of the scraper, being formed of wood the wedge 15 is particularly effective in clamping the grooved portion of the body onto the scraper. The band 17 may be prevented from becoming displaced from the body 10, in any suitable manner, for instance, suitable wood SCIQWS 20 may be arranged through the side 18, of the band, so as to extend into the body 10, shown in Fig. 2 of the drawings.

To move the wedge 15, either iuowardly so as to cause scraper 12 to be gripped in the inenner just described, or downwardly so as to cause the scraper to be released the I tor turns or rotates a nut 21 screw headed on a rod which is connected directly to the wedge 15. The rod 22 is preferably connected to the wedge 15 by rivets 23 and is shaped to extend inwardly from the wedge 15 through a recess 24L in the body and then upwardly through a bore 25 in the handle 18. The free or outer end of the rod projects, or extends, from the upper end of the handle 13 is screw threaded to can y the nut 21. she nut 21, although accessible and tree to be rotated is held against longitudinal d'splaceincnt by a metal strap 26 secured to the up; or end of handle 13 by he strap 26 positively suitable screws 27. 1 hOltS the nut 21 between it and the end of re handle 1o thereby preventing the nut n1 rooting longitudinall when it is roed. it will readily understood how tation of the nut 21 causes longitudinal movement of the rod 22 in bore 25 thereby causing movement of the wedge 15. The direction in whieh the wedge .15 nioved depends, oi course, upon the direction in which the nut 2i is rotated, and the force with which the wedge 15 is moved, that is, the force with which it is drawn between the band 1? and bod; 1, depends upon the force "it-h which the nut 21 is turned. It is preferred that washers 29 be carried on the "-en the end of handle 13 and the nut 21 and also between the strap 26 and the nut 21, as clearly shown in Fig. 2. It will also be noted in the drawings, particulsrly in 2, that the recess 2% is suiticiently large to allow proper movement of the rod. The full lines in Jig. 2 show the wedge 15 and the rod 22 in the extreme up position, or in the position where the wedge is drawn tightly between the l and and body, while the dotted lines in Fig. 2 indicate the down position of the wedge 15 and rod, or

the position to which the wedge 15 is moved relative to the frame 17 to allow oi the scraper 12 to be placed in or removed vfrom the groove 11.

Having set forth preferred embodiments of my invention 1 do not wish to limit or restrict niyselit to the particular details her inabove set forth but wish to reserve to myself any changes or variations that may appear to those skilled in the art or that may full within the scope of the following claim.

Having described a preferred l'orm ol' m v invention, 1 claim:

A tool holdercomprising a body formed with a groove to receive :1 tool, a handle on the body, a band extending around the grooved portion oi? the body, a wedge lying between the band and the bod and lll(|\'- able in a direction longitudinal oi the il:1Il-- dle to cause gripping of the tool, a rod eonnccted to the wedge and extending lon gillr dinally through the handle, the bodv being slotted and the handle having a longitudina bore to pass the rod, the end portion ol' the rod being screw-threaded, and a nut at lluend of the handle threaded on the rod.

In witness that I claim the loreg goin gy .l

have hereunto subscribed my name this 22d day oi March, 1920.
