VISE.

Application filed August 5, 190B.

lo all whom 'it may concern.'

Be it kno t. n that I, Iioisnn'r ALLEN Honniivo, a citizen olt the United States, residing at Lanark, in the county of Carroll and. State ot Illinois, have invented certain not." and useful Improvements in I)arallel-Jav: Vises, olI which the following is a specification.

This invention relates to power vises, and has particular reference to that class of devices `which are designed for use in connection r. ith work benches, or the like, and usually operated by hand.

Among the se 'eral ects aimed at in the present improvements are to economize space, secnre easy nranipulation of the movable portion ot the vise throughout its compass, and to save time in operation.

For a full understanding of the invention, including its construction and characteristic advantages, reference is to be had to the following detail description and the accom panying drawings, in hich,

Figure l is a side elevation, with certain parts broken array, showing in full lines the vise in a substantially closed position and in dotted lines, in its full openv position, and li ig. 2 is a transverse sectional detail on the line ol'v Ifig. I, showing vthe manner in which the irame constitutes a stop lor the bell crank lovers in the position indicated for the parts in dotted lines in Fig. l.

rldiroughout the following description and on the several figures of the drawings, similar parts are referred to by like reference characters.

This invention in its preferred embodiment comprises a stationary 16 having a stationary leg ll. Said jaw and leg may be secured in any convenient manner to any suitable type of support such as a bench l2. At any convenient point, preferably near the upper end, the stationaryT leg is provided `with an internally threaded hole 13, and below said hole are a plurality of transverse slots lil extending through the leg. A movable jaw 1,5 has the leg 16 arranged parallel to and movable in close proximity to the stationary leg 1l. The specific form of the jaws l() and l5 as well as the legs Il and 16 may be varied to a considerable eX- tent mithin the scope of this invention. As a convenient power means for operating the movable an', I provide in the movable leg 16 a smooth hole 17 in alinernent with the Specification of Letters Patent.

Serial No. 447,141.

threaded hole I3 aforesaid, and cooperating ith said holes is a suitable screw 18 having threaded connection with the stationary and loose rotary connection with the movable jaw. In order to prevent longi` tudinal displacement of the screw with relation to the movable jaw, the screw is provided `with a groove i8 into which projects a transverse locking bolt 19, the bolt being secured in the movable jaw in any suitable manner. The head 2() of the screw coperates with the outer face of the movable jaw in the customary manner and is operated by a handle 21.

The mechanism employed to cause parallel movement ot' the jaw 15 with relation to the jaw l0 comprises the following elements: A pair o1c bell cranks 22 and 22 pivoted in substantially the same plane within the stef tionary leg l1 and beneath the bench l2. As herein disclosed the means for supporting said bell cranks consists of tulcrum blocks 23 secured upon the inner 'lace of the stationary leg and within which blocks the bell cranks are pivoted upon pivots 24 and 24. One end oi each ot said bell cranks projects upwardly adjacent to its corresponding slot lll, and the other ends of the bell cranks are connected by a rigid bar 25, whereby the bell cranks are caused to operate simultaneously upon their pivots. A pair of guide links 26 and 26 are pivoted in sockets 27 and 27 on pivot pins 28 and 28 secured in the movable leg. Said links are guided through the slots le, and their inner ends are pivoted to the adjacent ends of the bell cranks. It will be apparent that the screw 18, links 26 and 26, bell cranks and 22 and bar 25 constitute the entire connecting means between the jaws and for this reason the ordinary 'lulcrum bar usually employed to support the lower end of the movable leg, and which requires frequent adjustment in accordance with the different sizes of work to be held,is dispensed with. In order to secure ease of operation ot a vise it is desirable that the screw have a loose threaded connection, and for this reason auxiliary guiding and sup porting means are necessary for the movable jaw. The links 26 and 26 serve therefor-e as such additional supporting and guiding means as well as to cause parallel movement thereof. Again, it is to be noted that the means herein en'iployed to cause parallelism whereby a minimum amount oi room 1s required for construction and manipulation of the vise. Heretofore parallel movements for vises have usually been disposed between the liaws, necessitating the use oi a great deal more room than is contemplated by this invention. v

The several parts oi' this invention may b constructed of any suitable materials and in various sizes and proportions, depending upon the exigencies in particular cases, without departing from the spirit oi thY invention hereinafter claimed.

Having thus described the invention, what is claimed as new, is:

l. The herein described parallel aw vise comprising, in combination, a stationary jaw having a supporting leg, said leg having an internally threaded hole and a plurality of guide slots therethrough, a movable jaw having a supporting leg parallel to said stationary leg, said movable leg having a smooth hole in alinement with said threaded hole and a plurality ot sockets in alinement with said slots, a power screw cooperating with said jaw holes, means to prevent longitudinal movement of the screw in said smooth hole, a plurality of guide links pivoted in said sockets and projecting through said slots, bell crank levers pivoted at their elbows adjacent to said stationary leg and at one end to the said slot-s and pivoted at their ends to said bell cranks and the movable leg.

3. A vise comprising, in combination, a stationary and its leg having transverse slots therethrough, a pair of fulcrum blocks secured on the inner face of said leg, a pair of bell cranks pivoted in the same plane to said blocks, a rigid bar connecting the bell cranks to cause simultaneous movement thereof on their pivots, a movable jaw and leg, power means to cause parallel movement thereof in close proximity to the stationary leg, and a pair of links pivoted to the movable leg and bell cranks and guided through said slots, substantially as set forth.

In testimony whereoie l my signature in presence of two witnesses.
