This invention relates to improvements in quick adjustable benchvises.

-Cabinet makers, carpenters and .other wood workers are consta-ntlysemploying a bench vise for holding the work under-preparation. Since theparts that :areworked on frequently differ greatly in size,- it becomes necessary to efiect a considerable adjustment of the vise in order to shift from one size of work to another.

The usual. bench vise is so'constructed that a vise head or block is moved longitudinally by means of a screw, preferably provided with square threads. .When a large adjustment becomes necessary, the screw must be rotated many times in order to move the vise head the required distance and this is time consuming.

It is the object of this invention to produce a bench'vise of such construction that it can be quickly adjusted, within the limits of its range, by merely turning the screw one or two complete turns in either direction.

This property of the vise is a great time saver and makes its operation simpler and more desirable than the ordinary vise. Having thus, in a general way, described the invention and the objectsthereof, the invention itself will now be described in detail, and for this purpose reference will be had to the accompanying drawing in-whichthe invention has been illustrated in its preferred form, and in which:

Figure l is a top plan view of a work bench showing the vise in positionthereon;

Figure 2 is a front elevation ofthe parts shown in Figure 1;

Figure 3 is a section, to a somewhat larger scale, taken on line 3-3,.Figure. 1;

Figurej l-lis a section taken on lines 44, .Figures 3 andl;

Figure 5 is a section somewhat analogous to that shown in Figure 4, but to a larger scale, and shows the position of the parts during the adjusting operation of the vise;

Figure 6 shows, by full lines, the position of the parts during the tightening operation and by dotted lines the position during the loosening operation; and

Figure 7 is a section showing a slight modification.

In the drawing reference numeral l9 designates an ordinary carpenters work bench. The top of the bench has attached thereto a strip H of the same thickness, which is provided with a number of square openings E2 in spaced relation. The openings may be positioned as close together .-1 Claim. (CI. 81-28) ,2 as desired, but can-not be spaced a greater distance than the range of the vise.

The vise to which the invention relates consists of a casting having an upper flange l3 and a downwardly extending flange M. Cast integral with flange M is a guide or enlargement I5. This is provided in its lower wall with a groove i 5 and in its upper wall with a groove I'l. At the end at the block is a'lug :8 that has an unthreaded hole through which the screw lilextends. Avise block or head 20 is attached to the inner end of the screw in the manner shown in Figure 3 to which reference will'hereinafter be made. Block 29 is provided with grooves 2| at its top and bottom, forming inwardly extending tongues 22 that fit into the grooves l6 and I1. Instead of the specific shape of the grooves 16 and I'Lthe guide and vise block-may have a dovetail interconnection such as is almost universa'lly employed in connection with lathes and illustrated in Figure 7. These two forms are equivalents for the purpose under consideration and will be'referred toas a dovetail connection. Block Edisslidable along guide l5'and is provided with an :opening23 of square or rectangular cross section. It is also provided with an openingf24 that'terminates. at 25. In axial alignment with opening 24 and extending inwardly from the side adjacentthe screw is a' countersunk opening '26, intozwhichthe cylindrical end of the screw extends, as shown in-Figure '3. A tap screw 21 extends through the wall of member 20 that separates openings Hand 26 and has a threaded connection with the end of the screw i9. Screw i9 maybe turned with respect to-block 20, but the latter will :be secured thereto for longitudinal adjustment along guide IS. A nut 28 is secured to thescrewilg and is provided with. outwardly extending wings 29 and 3d. The outer surface of part [5 is provided with transverse depressions 3| that are somewhat wider than the thickness of wings 29 and 3B. These depressions are of the shape shown most clearly in Figures 5 and 6, from which it will be seen that when screw I9 is rotated in a clockwise direction, when viewed as in Figure 5, wing 29 will enter the recess 3! corresponding to its position and may move into the position shown in Figure 6 where it engages the stop 32. When in the position shown in Figure 6, which is also the position shown in Figure 3, wing 29 serves as an abutment and if the screw is then rotated clockwise, when viewed as in Figure 4, it will force the block 20 towards the left in Figure 3. Stop pins 33, which have been indicated by dotted lines in Figure 2, are

positioned in holes l2 and 23, the one in hole l2 being positioned in accordance with the length of the piece worked upon which has been shown by dotted lines in Figures 1 and 2 and has been designated by reference numeral 35.

Let us now assume that the piece 34 is in position and the vise has been tightened. Wing 29 will then occupy the position shownin Figure 6. When the piece 34 is to be removed, the operator turns the screw in a counterclockwise direction, when viewed as in Figure 6, and after the pres,- sure has been removed, nut 23 will be rotated by the friction between it and the screw until wing 30 reaches the dotted line position in whichit extends into the depression 3 l :1. shown in Figured The rotation of the nut will now stop and any further rotation of the screw will move the head' 20 towards the right. If the piece 34 is to be replaced by a piece of the same length, the screw does not require to be turned more than one complete reotation to release the material and to move the head towards the right a sufficient distance to enable the new piece to be inserted. If a; piece considerably longer or shorter is to be substituted for the one that is removed, the operator, after the nut has reached the position shown in Figure 5, merely pulls screw is longitudinally until the head 2%! reaches the desired position, whereupon a rotation of the screw in a clockwise direction turns the nut into a position like that shown in Figure 6, whereupon further rotation .of the screw moves the block Ell into clamping engagement with the work.

When the nut 28 has a position relative to part [5 like that shown in Figure 5, the screw and the vise head can be reciprocated freely and by merely imparting a slight rotary motion to the screw, the parts are locked in the position in which they then happen to be, which position is determined by the length or'size of the article to be clamped between pins 33.

Since there is very little force necessary to move block away from the clamping position, the construction shown in Figure 3 by means of which the block and screw are interconnected is satisfactory; however, any other suitable means for effecting this connection can be substituted, if desired.

Attention is called in particular to part [5 and to the depressions 3| and Sla which are of such shape and'so related to the nut 28 and wings as and 30 that the nut cannot rotate a complete revolution. The two wings 29 and ill] have also one edge in alignment as shown in Figure 5 and a very small rotary movement is therefore sufficient to move the wings into or out of the notches.

The construction just described and shown in the drawings, is very simple and substantial.

The parts designated by reference numeral l3, M'and l5 may be cast as a unit and grooves l6 and I! made smooth by a milling operation or a planer. Block 2%] is also adapted to be formed from a casting and can be fitted to the slide with a minimum amount of labor.

The construction of the nut and the part [5 in the assembly shown on the drawing and described herein is considered to be of great importance in this device because the result of this arrangement is a quick adjustable vise of an extremely simple construction, having no weak part or parts that require any high degree of finish. The vise described and illustrated is of a strong and substantial design and can be manufactured and sold at a comparatively low price due to its great simplicity and at the same time the strength and quality of the vise as a whole is a maximum.

Having described the invention what is claimed as new is:

A quick adjustable vise comprising, in combination, an elongated base having a guide extending longitudinally on one side, a perforated lug at one end of the guide, a vise block slidably interconnected with the guide, a screw extending through the opening in the lug, one end of the screw being rotatably connected with the vise block, the screw being longitudinally slidable in the lug, a nut on the screw, between the vise block and the lug, the nut having angularly spaced wings, the surface of the side of the guide facing the screw having a plurality of longitudinally spaced transversely extending depressions for the selective reception of an end of each wing, the depressions having transversely extending stops between their ends to engage the ends of the wings and limit the rotation of the nut, the side walls of the depressions cooperating with the wings to hold the nut from moving longitudinally relative to the base when the screw is rotated to move the vise block.
