WORKBENCH.

Application filed March 18, 1925.

To all whom it may concern Be it known that we, O'rrro JOHN Youno- MAN and MAXIMILIAN R. YOUNGMAN, citi- ZGIIS of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in lvorkbenches, of

which the following is a specification.

This invention relates to work benches. An object of the invention is to provide readily adjustable means incorporated in the work bench for holding strips of material such as wood, for planing, sandpapering and the like, and to facilitate acco1nn1oda tion of the holding means to objects of greatly varying width.

A further object is the inclusion in :1 de vice of the type described of a vise arrangement which is quickly adjustable to any extension limited approximately only by the length of the work bench and to enable a board or other object being held in the vise to at the same time rest upon the top of the work bench. I

Other objects and advantages will be made manifest in the following specification of an embodiment of the invention illus-- trated in the accompanying drawing, in which- .Fig. 1 is a perspective of the work bench,

Fig. 2 is a top view of the work bench,

Fig. 3 is a fragmentary vertical section of a portion of the work bench taken. on the line 33 of Fig. 2.

Fig. 4 is azfragmentary vertical section of a portion of the work bench taken on the line 414 of Fig. 2, i

Fig. 5 is a fragmentary vertical section of the work bench and vise arrangement taken on the line 5-5 of Fig. 2, i

Fig. 6 is a fragmentary view of the side of the work bench top taken in the direction of the arrow 6 of Fig. 2,

Fig; 7 is a horizontal sectional 'fraginen tary view of the portion of the work bench shown in Fig. 6 and is taken in the direc tion of the arrow 7 of Fig. 6.

The details of constructionand operation of the invention are as follows A work bench top 10 is supported by suitable legs or standards 11 which are properly placed with end pieces 12 and side pieces 13; the supporting frame work may constitute any desired structure. T v

The top 10 is approximately rectangular Serial N0.'1,6,383.

which is disposed vertically and is parallel to the side 1 A wedge block which is herein. shown as rectangular in design and of sufiicient thickness'to provide a substantial obstruction is provided with a diagonally disposed tongue 21 which is adapted to slidably engage one of the grooves 14:, 15 and 16 and the wedge block to slide over the surface of the upper face of the top. It will be noted that the sides of'the wedge block are.

parallel to the sides of the top 10 and that the guide-way formed by the groove 16 will cause the wedge block to be moved to or from the sideof the top when the block is slid lengthwise in the groove.

A slide block 22, having a substantially U shapedcross section is adapted to slidably engage the side 18 of the top 10 and an upper extension 23 to slide on the upper face of the top and a lower extension 24 to slide on the lower face of the top. This slide block is formed with a tongue 25 adapted to slide in the groove 1'? and the lower extension is provided with a tongue 26 which is adapted to slide in the groove 19. It will thus be observed with reference to Figure 3 that the

cooperating tongues

25 and 26 act to prevent the slide block 22 from being moved in any direction except longitudinally of the side of the top. Thus the inner face 27 of the slide block presents a substantially rigid abutment between which and the wedge block 20, a piece of material may be wedged and held securely for being worked.

The side 18 has a plurality of recesses 28 into which a pin 29 operating through the slide block 22 is adapted to project for the purpose of securing the slide block against lengthwise movement. posed at the end of an arm 30 which ispivoted between a pair of ears 31 and has a The pin 29'is dis handle/32c at its opposite end A short lug 33 projecting oi-itward-ly from the'slide block 22 is adapted to retain an ezq ansion coil spring 34- which bears at one end on the slide block and at its other end onth'e arm 30. Thus the pin 29 is normally pressed. inwardly to effect an engagement with one of the apertures 28. The pin 29 however,

may be locked in an optwardor disengaged position by means of a swinging lock member which is adapted to he intenposcd be tween the arm 30 and thebl'ock and to otler an obstruction-to .the said arm, preventing the pin from entering any oi the apertures.

A block 236'- is formed with a cross section substantially identical to the cross section of the slide block .22 and is adapted to slide upon the side of the top and its tongues and 38 to engage the grooves 17 and 19: respectively. Oine end of the vise block 36 has arecess 3.) into which the hearing cud 4-0 ota-jack screw-{L1 is adapted to work, The bearings-2nd li'is formed with an annular groove 42 in which a set screw $1 3 is adapted to be extended lor preventing retraction-oi the jaokserew 41 from the vise block The jack sore-w i1 is threaded through an extension is at the end of the top and, a crank 45 is provided at the outer end of the jack sore-w.

- The operation oil'the invention may be understood as follows:

A board'strip oat" material or other object which is to be worked may be laid iupon the top of the work bench and one edge brought adjacent the face 27 of the slide block 22. An approximate adjustment may be etleeted by inserting the tongue 21 on the wedge block 20 in the pnoper one of the grooves 14: 15 and16. A more minute adjustment as to operation by the slide block 22 and the wedgeblock may be effected on releasing the pin 29 from its position in one ofthe recesses 28 by means of the handle 32 on the ar1n30-and the slide block 22 may he slid along theiside 18 of the top 10 to the desired position. The object may then be tightly wedged between-the two blocks by pushing the block 20 in the direction which will cause the said block to draw nearer to the side of the'itop. The object may be released by arring the wed-geblock 20 in the opposite direction which willhavethe efl'i-mt of pulling the said wedgebloek .away from the object being held. The USG' Oflth-G vise arrangement contemplates cooperation betweenvthe slide block 22- and the vise block 36. The lirst approximate adjustment may he made by disposing the slide bloek'22 in the desiredpositionwalong the side 18' and the pin 25 should he allowed to enter one, of the rocessesQ-S tothci'cby secure the slide block lVhatever =worked on :shouikl placed against the upper extension 23 of the slide block 22 and may be tested upon the top or otherwise and the vise block 36 tightened against the object by rotating the crank on the jack screw il-1.
