VISE.

Application filed August 17, 1916.

To all whom it may-concern:

Be it known that L-Gimronn M. Yos'r, a citizen of: the United States, residing at Cleveland, ,in the county of Cuyahoga and State of Ohio, have invented a'certain new and useful Improvement in 'Vises, of x which the following is a full, clear, and exactdescription.

[This invention relates to Vises, and particularly woodworkers -vises. The invention has particular reference also to what is known as quick-actingor quick-release vise, and also to theso-called universal vise, the jaws of which can be positioned oradjusted to various positions. with respect to the bench or other support on which the vise is mounted, and the movable jawof which can be adjusted by the screw or can be released and slidin or out relative to the normally stationaryv aw.

Theprinciple object of theinvention is to provide certain improvements which render the vise more eflicient and durable, and also to improve the jaw-adjusting ineans,.par-. ticularly the mechanism by which the adjusting screw and its associated nut are ongaged or released so as to permit either the regular screw adjustment or the quick slid ing movement of the movable. aw.

The invention may bebriefiy summarized as consisting in certain novel detailsof construction and combinations and arrangements of parts which will be described in the specification and set forth in .the appended claims.

In the aceompanyingsheets of drawings, wherein I have shown two slightly different forms of my invention: Figure 1 is a top plan View with the vise detached from the bench and with the supporting bracket for the brace rod in section; Fig. 2 is a side elevation of the same with the bench shown in outline; Fig. 3 is avertical sectional view, the section being taken substantially centrally and longitudinally through the vise attached to the bench, this view showingaby dotted lines the vise jaws-tilted to a position at-an angle to their normal position; Fig. 4 is a transverse sectionalview substantially along the line H of Fig. 3 look ing in; the direction indicated by the arrow. Fig. is a front view with the operating handle in section substantially along the line 5-5 of Fig. 3 looking in the direct-ion indicated by the arrow; Fig. 6 is a plan view Specification of Letters Patent.

Patented Mar. 25, 1919."

Serial No. 115,362.

with parts in section showing the major portion of avise embodying-a slight modification of my invention; Fig. 7 is a view looking toward the front jaw of Fig. 6 with the front cap removed and with the operating handle in section substantiallyalong the line -77 of Fig. 6 looking in the direction indicated by the arrow.

Referring nowto the drawings, and first to ,Figs. 1 to 5 inclusive, 10-and'11 represent thetwo jaws of the vise, the latter being the front jaw and being, movable toward and from the former, and both being simultaneously movable in avariety of directions, as will be explained.

The exact construction or shape of the jaws is a matter of on consequence, their adjacent faces being preferably fiat and both being preferably provided with endwise movable dogs 12 in which, however, Iclaim no novelty herein.

In order thatthe vise may be attached to a support such as a bench13 I utilize a hinge, includinga leaf or stationary hinge member14, which is designed toy'be attached to the top face of'and-to extend over the. front edge of the bench, and a second hinge member 15 which is hinged'or; pivoted-to the first by means of a horizontal pin; or equivalent. securing device 16. The hinge member 15 which normally,projectsdownwardly is provided withan annular split sleeve or hub 17 whichis normally. beneath and at the front edge ofthe benchas shown in Fig. 2. This annular. support; or split sleeve which is designedto be'loosencd or tightened by means of a movable clamp lever 18 receives a cylindrical extension, or boss 19 projecting rearwardly from the rear or inner aw 10;

Secured to the front jaw 11;and extending through the relatively stationary jawlO is a pair ofguide rods 20 which pass through bearing. openings in'the jaw 10 audits-cylindrical extension 19 and at-their rear ends are held. a predetermined, distance apart by a connecting. yoke or cross pieceQ-l; (see particularly Fig. 1). Between these guide rods 20 is a threaded adjusting screw 22 which turns in but moves longitudinally with the front jaw and has a bearingin: the rear cross piece or yoke 21; The frontend of the screw is providedwith the customary rotary handle 23.

In order that the front jaw may be moved toward and from the relatively stationary rear jaw when the screw is turned, I provide in the cylindrical extension 19 of the rear jaw a nut or nut segment 24 which is held from endwise movement and also from rotary movement in the cylindrical extension, so that when the handle 23 is turned the screw and front jaw 11 travel inwardly or outwardly.

One of the novel features of the invention resides in the means for effecting the quick release by which nut and screw may be disengaged at the will of the operator, so that the front jaw can be slid inwardly or outwardly toward and from the relatively fixed jaw 10 without turning the handle. The means for thus releasing the nut from the screw or for causing the nut to disengage the screw includes a rather long cam shaft 25, which at its front end is connected with the front jaw and has a sliding engagement with the rear j aw, this shaft being just beneath the screw, as shown in Fig. 4. This shaft, which is substantially the length of the screw and guide rods 20 has a section or segment removed for nearly its entire length so as to present or form a fiat surface, and it is so disposed relatively to the nut that if it is turned so that the fiat face is next to the nut the nut may drop away from the screw or threaded shaft, a spring being preferably employed to shift the nut from the screw in the event gravity can not be relied on for this purpose, but when the shaft is turned through about turn so that the round portion of the shaft engages the nut,

it lifts the nut upwardly and holds it in engagement with the screw. In this case the spring which moves the nut away from the screw is in the form of a wire 26 which extends through the nut and has its ends entering into the wall of the cylindrical extension 19 of the rear jaw 10. When the nut is pressed upwardly by the cam shaft this spring is put under tension so that when the shaft is turned so as to release the nut the spring will immediately pull the nut from the screw. In order that the nut may be quickly and conveniently released from the screw the rod 25 which projects a distance beyond the front jaw is provided at its outer end'with a finger 27 which is turned in a -counter clockwise direction, as viewed in Fig. 5, to release the nut and is returned to normal position when released so as to cause the nut to be carried back into engagement "with the screw by a spring 28 whichsurrounds the forward portion of the cam shaft (see particularly Fig. 3).

If it is desired to simultaneously turn.

bothjaws about the axis of the-feed screw. this can be done by loosening the split'collar 17 by means of the clamp lever '18. If it is desired to tilt both jaws relatively to the bench about the axis of'the hinge this can be readily done. One position of the jaws when so tilted is shown by dotted lines in'Fig. 3. In order that the jaws maybe held tightly in any position to which they may be tilted, I provide a brace rod (see Figs. 1 and 2) which at its forward end is provided with a head 31 pivotally connected by a screw orbolt 32 to the cylindrical split clamp 17 this brace rod likewise passes through a split sleeve 33 oivotally supported on a bracket 34 which extends downwardly from the lower side of the bench, as shown in Figs. 1 and 2. By means of a clamping lever 35 this split sleeve can be caused to clamp the rod 30 at any point thereof, or by loosening the same the rod can be slid through the sleeve. To tilt the jaws the sleeve is loosened so as to permit the jaws to be tilted to the proper position, the rod 30 at such time sliding through the sleeve and when the jaws are in proper position the sleeve will be tightened onto the rod 30 by the clamp lever 35, whereupon the jaws will be held firmly in the position to which they have been moved.

In Figs. 6 and 7 I have showna construction which is like that first described, except that an additional adjustment is provided, this adjustment being the tilting of the front jaw relative to the rear so that the adjacent jaw faces can be caused to assume a position tapered or inclined relative to each other instead of thenormal parallel relation.

In order that this may be accomplished the front jaw here designated 11 is pivoted by means of a pin or equivalent pivoting device 40 to a head 41 to which the forward ends of the guide rods 20 are secured and in which the screw has a bearing as in the first instance. This head 41 is forked as shown particularly in Fig. 7, and extending into the fork from the j aw 11 is a rib-like extension 42 which is rigid withthe jaw. J 0ur naled in this rib 42 is an adjusting screw 43 which passes through a nut 44 in the form of a cylindrical pin which is movable lengthwise of the shank of the adjusting screw in a slot 45 of the ribextension 42. The ends of this nut or cylindrical pin 44 extend into a suitable slot of the fork of the relatively stationary head 41' so that when the adjusting screw is turned this nut which travels along the screw tilts the jaw 11 relatively to the stationary jaw 10, as will be readily understood by' reference to Figs. 6 and 7. The head and'the adjacent portions of the movable jaw 11 are preferably inclosed in a cover 46 through which the head ofthe adjusting screw 43 projects.

adjusted by means of the screw,,or the front jaw canbe slidindependently of the screw toward and from the rear jaw by releasing the-nut from the screw. The mechanism is convenient to operate'and atthe same time the-construction is strongand durablein all respects In-addition to theadjustments of which the construction-shown in Figs 1 .to 5 is susceptible the vise may be given the adjustment shown in Figs. (5 and 7 by which the frontjawcan be tilted irelatively to the rear jaw without in any way affecting the other adjustments, it being understood that the vise shown in Figs.- 6 and 7 will be provided with the quick-acting mechanism including the nutrelease which is precisely like that first described, and that. the jaws will be mounted so that theymay be tilted or turned'precisely as'in the first instance.
