JOSEPH GOODRIOH, OF CHICAGO, ILLINOIS.

VISE.

SPFEGIFICATION forming part of Letters Patent No. 593,649, dated November 16, 1897.

Application filed August 7, 1897'- To all whom it may concern;

Be it known that I, JOSEPH GOODRICH, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vises; and I dodeclare the following to be a full, clear, and exact description of the invention, such as will-enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to that class of Vises in which the jaws can be quickly adjusted to the size of work to be operated upon and then by a supplemental action tightened upon the article inserted between them.

The object of the invention is to secure quick and reliable action and to provide for the control of the jaws wholly by means of pedals, so that the hands of the operator shall both be free to adjust the work. These objects are attained by the parts and arrangement of parts, as hereinafter fully described, and illustrated in the accompanying draw- Figure 1 is aside elevation, of the vise. Figs. 2 and 3 are sectional details onthe lines 2 2 and 3 3, respectively, of Fig. 1. Fig. lis a detail elevation, and Fig. 5 is a sectional View on the line 5 5 of Fig. 4.

In'vises of this type it is important that in spreading the jaws. maintain their parallel relation, so that in gripping the work their cooperating faces are substantially parallel whether the article inserted between them is large or small. It is furthermore greatly to be desired that when the lever movement is employed in tightening the jaws upon the work the movable jaw be a lever of the first class, because of the great power of such a lever. I therefore employ a fixed and a movable jaw and swing the latter upon an adjustable pivot, means being provided for locking in its adjusted position the bar to which the jaw is pivoted. I further provide a pedal-controlled set of levers for spreading the jaws and springs for automatically closing them when the lever-pressure is released. I also provide a clutch for holding the slidebar, which carries the pivot of the lever. or

clamping-jaw, and an automatic controlling mechanism for releasing the clutch to admit of the adjustment of the jaws and reengage it when they are closed upon the work. Mechanism controlled by a pedal is also provided for rocking the lever-jaw upon its pivot for the purpose of firmly compressing it upon the work and by which'it may also be released. The use of the hands in adjusting the jawsto the work is therefore wholly obviated.

The fixed jaw A is adapted to be secured to a bench, as X, as shown at a, and to have shown at a. The movable or clamping jaw is shown at B and is pivoted atc to a slidebar 0, which freely moves in a transverse slot in the jaw A sufficiently below the head below. the bar 0, and f, located below the bar E, connect and draw together the jaws A B.

A pair of spreading-levers- G G are pivoted in vertical alinement to the jaw A, between the bars 0 and D, and are adapted to bear against the jaw B; These levers are each provided at its outer end 'with a roller 9 g, and the face of the jaw is channeled to receive them. A link-bar h connects the two levers G G and is prolonged downwardly and provided with a pedal H. The lower end of the link-bar h may be provided with ratchetteeth, as shown, to cooperate with a fixed pawl h, attached to the jaw B, so as to hold the jaws apart.

A clutch-block in the form of a roller K is set within .a recess is in the rearward side of the jaw A, so as to cooperate with the slidebar 0, the face of which is preferably roughened, as shown at o. oted between'a pair of bracket-arms Z, projecting laterally from the upper end of a spring-rod L, the lower end of which is socured to the jaw A, as shown at Z. The rod The roller K is pivits lower end mortised into the floor Y, as

L not only serves to carry the roller K, but by its spring action to hold it normally in engagement with the slide-bar O and the wall of the recess 7a.

The release mechanism for the clutch comprises a thrust-pin M, passing through the jaw A and bearing against the upper end of the rod L, and a cam-rod O, cooperating with the head on of the thrust-pin M. The rod 0 is pivotally attached to the lever-arm G, and the parts are so disposed that when the leverarm G is in its elevated position, as shown in solid lines in Fig. 1, the pressure upon the pin M of the cam portion of the rod 0 is relieved, so that the clutch-block K is forced into the recess is. As it is necessary that the clutch mechanism be released before the jaws of the vise can be spread the roller ends of the lever G G are normally slightly removed from the face of the jaw B. lVhen pressure is applied to the pedal 11 to throw these lever-arms down, the first action is to release the clutch mechanism.

A mutilated gear-wheel P, having a portion of its periphery smooth, as shown at 1'), is located between the slide-bars D E, so as to cooperate with the racks (Z c. This gearwheel is fixed upon a spindle R, which is journaled in horizontal slots in plates Q q, fixed to the jaw A. The spindle R is provided with a crank-arm 0', which projects loosely through a slot in a lever-arm S, pivoted at s to a plate T, fixed to the jaw A. The lever S is provided at its forward or free end with a pedal-piece 8, whereby it may be depressed against the resistance of a spring i, secured to the plate T. A spring-pawl U, carried by the lever S, cooperates with a ratchet 25, formed upon the plate T, so as to lock the lever S in any position to which it may be adjusted. The gear-wheel P is so set that when the lever S is in its elevated position the plain portion 1) of the gear is ad jacent to the rack 0, so that the bar E is released from engagement with the bar D and leaves the jaw free to move as pressure is applied to the pedal II.

In operation the foot of the user is applied to the pedal H in order to spread the jaws sufficiently to receive the work to be adjusted in the vise. The work having been inserted pressure upon the pedal may be at once released, allowing the jaws to close so as to grip the article and permitting the lever-arms G G to be drawn upwardly by the action of the spring g, thereby removing the cam-face of the rod 0 from the head of the pin M and permitting the clutch-block to enter into engagement with and thereby lock the slide-bar C. The foot is now applied to the pedal 8' so as to oscillate the gear-wheel P, which at once comes into engagement with the rack e and moves the lower end of the jaw B still farther away from the jaw A, rocking the jaw 13 upon its pivot-pin c, and thereby tightening the grip of the jaws upon the work, the pawl U engaging the ratchet 25, so as to maintain this grip. In order to remove the work from the vise, the pawl U is disengaged from the ratchet and the springt throws up the lever S, thereby rotating the gear P and drawing in the lower end of the jaw 13, so as to loosen the grip upon the work. If necessary, the foot may again be applied to the pedal H, so as to still farther spread the jaws, and, if desired, the ratchet of the link-bar h may be engaged with the fixed pawl h, so as to hold the jaws in their spread position against the action of the closing-springs F f.

It will be seen that the manipulation of the vise is wholly by pedal action, and that the gripping is accomplished by a system of levers of great power, so that as much pressure may be placed upon the work as may be desired. It will also be seen that the action is very quick, the spreading being accomplished without any loss of time, and the gripping mechanism being ready for action without lost motion to whatever position the jaws may have been adjusted.

I claim as my invention 1. The combination in a vise, with a fixed jaw, a clamping-jaw, a transverse bar in sliding engagement with the fixed jaw and in pivotal relation with the clamping-jaw, and a clutch for loekin g the fixed jaw and the bar together, of pedal-actuated means for releasing the clutch and moving the clampin gjaw away from the fixed jaw.
