Application filed January 8, 1914. Serial No. 810,956.

To all whom t may concern Be it known that I, CHARLES E. FISH, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Hand-Vises, of which the following is a specication. y

This invention relates to hand-vises and has for its object the construction of a strong and durable vise having parallel jaws, and

actuating-means for said jaws which are independent of the jaws and adapted to be i moved into and out of engagement therewith quickly.

The vise embodying this invention has a pair of jaws connected by links with a frame whereby they are caused to move in parallel l relation, said jaws having their inner ends formed with seats for engagement with the actuating-means and the actuating-means comprises a screw with hand-engaging means for turning it arranged at its outer end, said screw being extended through a smooth bore in the frame whereby it is permitted to slide freely therein, and having at its inner end an abutting block for engagement with the' seats at the inner ends of the jaws and al pair of dogs pivoted to the frame having threaded engaging faces for engaging the threads ofsaid screws and having linger-en gaging means byV which they may be moved on their pivots to disengage the screws, return movement thereof to normal being e'ected by means of springs which are associated therewith. v

Figure 1 is a side elevation of a hand-vise embodying this invention. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal horizontal section taken on the dotted line 3 3 of Fig. 2, and, Fig. 4 is a similar view, the actuating-means for the jaws being removed from engagement therewith.

The frame, as here shown, consists of a block 10 and a pair of long side plates 12, 12, rigidly secured at one end to the opposite ends of said block. Said side plates may be of any suitable shape, so far as my inventionis concerned, although they are here shown as made quite wide for aportion of their length and quite narrow for the remainder of their length, the wide portions being arranged adjacent to the block 10 and the narrow portions being remote therefrom.

14: and 16 represent the jaws which are shown, each-jaw consists of a 'bar having that side adjacent to the other jaw formed A with a grooved, or it may be a flat face, for engagement with a rod, wire or otherwork to be engaged by the jaws; and having its end beveled from the outer side toward its inner or work-engaging face and having its outer side -formed with a longitudinal channel'and having its front and rear faces made flat for connection therewith of links which support it and to permit unobstructed movement of said links as the jaws are moved; and having its inner end made liat or otherwise to form a seat for engagement therewith of the actuating-means. Said jaws are made of a thickness somewhat less than the distance between the side plates to provide for the links. `Each jaw is here shown as connected by two pairs of links with the side plates 18 and 19, 2O and 21, 22 and 23, 24 and 25 representing the links and said links are pivotally connected at their outer ends to the front and rear faces respectively of the jaws and at their inner ends to the side plates, and for simplicity of construction four pivot pins 26, 27, 28 and 29 which are extended transverselythrough the jaws nections for the inner ends of the severalv links. By means of these connections ofthe jaws with the side plates they are caused to move longitudinally in paral el relation, yet my invention is not limited to this particular means of connecting the jaws with the side plates. I prefer, however, to employ parallel moving jaws on account of the long work-engaging faces which they will present in allpositions.

The actuating-means for the jaws is, as before stated, independent of the jaws and is adapted for quick opera-tion, and, as here shown, said actuating-means comprises a screw 35 which is extended through a smooth bore in the block 10 permitting unobstructed longitudinal movement thereof, its outer end-portion having secured to it a cross-bar inner end-portion being arranged between` the side plates and having at its inner end a block 37 with a fiat or other face `for engage.

ment with the seats formed on the inner ends of the jaws. The block 37 is swiveled or otherwise loosely connected with the screw permitting a turning movement of the screw independently thereof while the block .itself is free to slide between the side plates without turning.

The screw is normally engaged by a pair of dogs 40, 4l which are made alike but oppositely disposed. Each dog is arranged between the side plates and pivoted to the block l10, 42 representing the pivot pins and each dog has a threaded engaging face 43 of considerable length for engaging a plurality of threads of the screw, and each dog has a linger-engaging portion 44 which is serrated and which is readily accessible, being eX tended outward beyond the end of the block, 1 whereby it may be moved on its pivot to disj engage the threads of the "screw,I and each dog has a spring 45 associated with it for holding its threaded screw-engaging face normally in engagement with the screw. It is very desirable that normal movement of the dogs shall be limited, so that their engagement with the threads of the screw will not be too severe when subjected to strain, as, in such case, the threads of the screw as well as those of the engagingfaces 'are liable to become injured, and to accomplish this result the bottoms of the slots in the ends of the block l() are arranged to serve as abutments for the dogs and the dogs are cut away to receive said abutments and admit 'of the engaging portions thereof extending over the ends of the abutments, and said abutments are of the proper dimensions, so that when engaged by the dogs said dogs lwill correctly engage the threads of the screw.

Inoperating the device, assuming that the block 37 is removed from engagement with the jaws, the jaws may be separated to rec'eve the work by moving them longitudinally by pressureexerted upon them at their outer ends or if the links are sufficiently loose they may be moved by gravity. The work having been placed in a position between them, the screw 35 is moved quickly a longitudinal direction, the threads 'thereof slipping beneath the dogs until the block 37 strikes the inner ends of the jaws,

then the screw is turned by manipulating the hand-engaging means to positively move the jaws longitudinally and cause them to firmly 'engage the work. To remove the work the screw is turned slightly to relieve the pressure on the dogs, then the dogs are moved on their pivots to disengage the screw, whereupon the screw may be moved quickly outward in a longitudinal direction and the jaws ermitted to separate. y l I The block 37 and screw 35 are here shown `is a rod or wire, at least no larger in diameter than the diameter of the bore, it may be extended through said bore any desired distance.

I claim l. The hand-viseherein described consisting of a frame, a pair of jaws having a parallel motion pivotally connected with said frame, said jaws having seats at their inner ends, actuating means to move said jaws longitudinally involving a screw slidably mounted inthe frame having handLengag'ing means for turning it, and means borne by said screw for engagement with the seats on said jaws, a pair of pivoted dogs having threaded engaging faces normally engaging a plurality of threads of the screw and hav; ing a readily accessible finger-engaging portion by which pressure may be exerted thereupon to move them out of engagement with the screw whereby the screw may be turned while engaged by the dogs and may be slid longitudinally when the dogs are disengaged therefrom.

2; The hand-vise herein described consistxing of -a pair of side plates attached to a block, said block having a smooth bore through it, a pair of jaws arranged for parallel motion pivotall connected to said side plates and having their inner ends formed with seats for engagement therewith of the actuating means, a screw extended through said bore in the block and slidable longitudinally therein having its inner end-portion arranged between the side plates andhaving 'at its inner end a swiveled block with a flat -face for 'en'l agement with the seats at the inner ends o the jaws, said screw having 'at its outer end hand-'engaging means for turning it, and a pair of pivoted dogs arranged between the side plates and normally engag ing the screw having threaded engaging faces for engaging a plurality of threads of the screw and having readily accessible inger-engaging portions by which pressure may be exerted upon them to move them on their pivots to disengage the screw, and springs to normally hold said dogs in engagement with the screw. Y 3. The hand-vise herein described consistjing of a frame, a pair of jaws connected ltherewith, quick adjusting actuating-means for said jaws comprising a screw slidably mounted in the frame having hand-engaging means for-turning it and arranged for actuating the jaws when turned in one direction, a pair of pivoted dogs having threaded engaging faces for engagement with a plu ralityA of threads of the screw and having linger engaging portions extended beyond the frame bearing tl'renfiA for moving them out of engagement with the screw,the frame bearing said dogs having abutments and the name to this specification in the presence of dogs having out away portions to provide two subscribing Witnesses.

for engagin said abutments thereby to limit their moveient toward the screw, and CHARLES E FISH' 5 springs to hold said dogs normally in en- Witnesses:

gagement with the abutments. B. J. NOYES, In testimony whereof, AI have signed my H. B. DAVIS.
