Referring to the drawings in detaihwherein similar reference j characters designate corresponding parts throughout the severallviews, the letter V generallyindicates myimproved-vise or clamp and thesame includes a' casting or frame I0. I j v This casting orframe I0 embodies a base II which can be secured to a work bench,.machine or the like and if preferredfthe base-can-be of a swivelled type so that the vise can be swung around in an arc of a circle. The casting IOalso includes a hollow housing lZ whichis'formed directly on the base and the upperend of the aohhousing has formed thereon the rigid jaw l3.
Slidably' mounted through'th housing I2 for.
longitudinal movementisa pair of bars or beams I4 and I 5. These bars or beams I4 and I5 are arranged in spaced parallel relation and'one 5, -above the other in a vertical plane. The forward ends of the bars or beams l4 and I5 ha'verigidly fastened thereto the movable jaw I B'and hence the movable jaw and the bars or beams I4 and I5 slide back and forth as a'unit.' A handgrip 40, I1 can'be provided for the moavble'jaw so as'to facilitate the'sliding' of said jaw. The rigid jaw I3 and the movablejaw Hi can be provided with anvpreferred type-"of jaw. faces I8 and I9 and the iawrfaces'preferably extend beyon'd'the body of the vise. Hencecthe jawsextend laterallybe'yond the bars or beams-I4 a'nclIS and as thebars or beams I4 and I5 are: arranged at the centerof the vise, work can: be readily gripped by the jaws on opposite sides of thebarsor beams.
I This is of a decided advantage whereielongated Work is beingheld in. :a 7 vertical plane.
Disposed within;the-hollow l'lousingv I2 of the r casting or frame .ID of the viseris .my improved;v locking mechanism 20 for the bars or vise beams" and-15,= r
The bars or beams M and I5 are locked,'advanced or retracted by the mechanism 2|! and this mechanism 2|] includes a pair of spaced clamping plates 2| and 22 for the bar or beam i4 and a like pair of clamping plates 23 and 24 for the bar or beam I5, and all of these plates are provided with openings 25 through which the bars or beams extend.- The openings 25 are of a slightly greater diameter than the diameter of the bars or beams.
The front plates 2| and 23' of the clamping -mechanism 20 are provided with overlapping interengaging ears 26 an the upper front clamping plate 2| is provided with a reduced finger 21 on its upper end. The lower plate 23 is provided with a similar depending finger 28. These fingers 21 and 28 are engaged by adjustableset screws 29 and 30 respectively.
A spring pressed plunger 3| is carried by the frame or casting l0 and engages the overlappin ears 26 of the plates 2| and 23 and hencethis plunger normally tends to cant or tilt the plates 2| and 23 on their bars or beams M and 15.
The rear clamping plates 22 and 24 have overlapping ears 32 and these ears are similarto the ears 28 on the front plates 2| and 23. Expansion springs 33 are coiled about the beams or bars l4 and I5 and are disposed respectively between the plates 2| and 22 and the plates 23 and 24. Similar relatively heavy expansion springs 34 are also coiled about the beams l4 and I5 and these springs engage the outer faces of the rear plates 22 and 24 and the inner face of the housing 52 of the vise.
Extending transversely through the hollow housing I2 is a rotatable crank shaft 35and the crank or throw portion 36 of this shaft is arranged between the pairs of plates 2| and 22 and 23 and '24 directly in rear of the spring pressed plunger 3| and atthe points of interengagement of the plates by their ears 26 and32.
Suitable bearings can be provided in the frame housing I2 for theshaft 35 and one end of the shaft carries any preferred type of manipulat-.
at right-angles to the longitudinal axis of the bars or beams I4 and I5. Hence the movable jaw I6 and the bars I4 and I5 can be conveniently slid back and forth.
Considering that work is to be done, the movable jaw I6 can he slid toward the rigid jaw to an initial position for loosely receiving the work, which is indicated by the reference character W.
When the movabl jaw l5 has been slid to its initial adjusted position and the work W is placed between the rigid and' movable jaws, the lever 31 is swung down'by the operator. With the initial turning of the shaft 35, the throw portion 36 thereof will be moved away from the ears 23 of the front plates 2| and 23 and the spring pressed plunger 3| will function to push in on the inner ends of the plates 2| and 23 to tilt the same on the beams l4 and I5. As the throw portion 36 moves away from the ears 2 B of the front plates 2| and 23, the same is moved into engagement with the ears 32 of the rear plates 22 and 24 and hence these plates will be tilted against the tension of the springs 34. The opposite diagonal corners of the walls of the openings 25 will grip the beams when the plates are tilted and upon continued dowward movement of the handle 31, the throw portion 33 of the shaft will be further moved into engagement with the cars 32 of the plates 22 and 24 and this will shove the beams l4 and I5 rearwardly and move the movable jaw l6 into tight gripping contact withthe work and the beams will be locked against movement.
When it is desired to release the work, it is merely necessary to swing the handle 31 upwardly and the throw portion 36 of the shaft .35 will be brought away from the plates 22 and 24 and toward the plates 2| and 23 and the plates will return to their initial position. This not only releases the clamping of the beams or bars I4 and I5 by the plates, but the movement of the plates back to their normal position will push forwardly on the beams or bars so as to slightly move the jaw I3 away from the jaw l3.
Great stress is laid on the novel arrangement of the overlapping of the inner ends of the sets of locking plates, whereby only a single throw or operating member is needed to actuate the plates to their locking position.
Obviously, I can employ only one plate for each bar or beam and where only one plate is employed, a bar or beam will ,still be efiiciently locked.
'Varioustypes of operating means can be employed for operating the clamping plates and in Figure 4 I have shown a clamping plate and this clamping plate receives the sliding bar or vise beam 4|. One end of the plate is provided with a finger 42 and this finger can be engaged by the cam portion 43 of a swinging cam lever 44. The camlever can be mounted upon a stub shaft or pivot pin 45 carried by the frame or housing of the vise.
In lieu of using a cam lever for engaging th finger 42, I can provide a set screw 46 (see Figure 5) for engaging the finger 42.
In Figure 6 I have shown a sliding wedge bar 41 for engaging the finger 42.
Obviously, other means for actuating the clamping plate 40 will readily suggest themselves to persons skilled in this art.
In Figure 7 I have shown a modified form of clamping plate 50. This clamping plate 50 includes a pair of openings 5| for receiving a pair of vise beams or bars and this clamping plate is provided with laterally extending finger 52 disposed between the openings 5|. Any suitable means, such as I have shown in Figures 4, 5, and 6, can be employed for engaging the finger 52 for tilting the clamping plate on the vise bars or beams.
Various changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new is:
1. A vise or clamp comprising a frame, a fixed jaw on the frame, a pair of freely slidable vise beams engaging the frame, a movable jaw rigidly secured to the beams, a tiltable clamp plate for each beam, the inner ends of the clamp plates being arranged in overlapping relation, spring means engaging the plates on one side for normally urging the plates to a substantially right angular position relative to the beam, and a mandirection of the movement of the beams and movable jaw to a work clamping position.
2. A vise or clamp comprising a frame, a rigid law on'the frame, a pair of beams freely slidable i said frame, a movable jaw rigidly secured to said beams, a pair of clamp plates tiltably mounted on each beam, the inner ends of said pairs of clamp plates bein arranged in overlapping relation, an expansion coil spring mounted on each beam between the plates of each pair of plates, an expansion coil spring on each beam disposed between one plate of each pair of plates and an adjacent part of the vise frame, a spring pressed plunger engaging the overlapping portions at the outer faces thereof of the other plates of each set of plates, and an operating member disposed between the overlapping portions of the pairs of plates.
3. A vise or clamp comprising a frame, a rigid jaw on the frame, a pair of beams freely slidable ed on each beam, the inner ends of said pairs of clamp plates being arranged in overlapping relation, an expansion coil spring mounted on each beam between the plates of each pair of plates, an expansion coil spring on each beam disposed between one plate of each pair of plates and an adjacent part of the vise frame, a spring pressed plunger engaging the overlapping portions of the outer faces thereof of the other plates of each set of plates, and an operating member disposed between the overlapping portions of the pairs of plates, said operating member including a rotatable cam shaft and an operating handle.
