; arrfn To all whom it may concern:

Be it known that I, WILLIAM SHANNON, a citizen of the United States, residing at- Ea'st .(lleveland,in the county of Cuyahoga and State of Ohio, have invented a certain new and useful which the folloy exact description,

Improvement in Vises, of ing is a full, clear, and reference being had to the The object of this invention. is to provide a simple and etlicientvise, adapted for ready attachment to a suitable support and capable ofmonvenientand quick operation in clamping and releasing articles.

he invention is especially well adapted for embodiment in a plumbers or steam fitters vise which may be easily attached to a plank, bench, or other support, and, when attached, is adapted to receive and clamp pipes, or other objects, by a simple movement of an operating lever.

.The invention is hereinafter more fully explained and. the essential characteristics are summarized in the claims.

The drawings clearly illustrate of my invention. I

the vise. To secure the vise to such support, I provide the plate 2 with ears 6 on its end through which are openings 7 adapted to receive' bolts. Similar openings 8 in the top plate 5 may receive bolts. In ad dition to such clamping feature, I prefer to provide a pair of clamps on the rear side of the plate 2'. Theseclamps are made by with the plate and proecting rearwardly, and suitable thumb screws 10 screwing through these brackets. The thumb screws provide very simple means for temporarily securing the frame on a plank or the edge of. a bench or table.

Pivotally mounted'wit-hin the recess 4 are a pair of clamping jaws 11 jaws are pivoted at 13 and 14, respectively," by studs mounted in the frame plate and cover plate. The jaws. are formed as shown in Fig. 1; that is, above the recess they have clamping portions, have curved extensions 15 and 16, respectively. Between these extensions is a suitable double-faced cam 20, which is provided with aprearwardly extending stud 21 jour naled in the back plate 2 and with a stud 22 journaled in and projecting through the front plate, these two studs forming an axle tor'the' cam. The stud 22 has a non-circular or angularextension or shank 23 to receive and lie-rigidly connected with-the operating handle 30. v

' he operating handle referred to is shown in Figs. 2, 3 and 5. It has an angular or other non-circular eye 31 extending over the non-circular shank 23, in front of the cover plate. The handle has its extreme portion formed as at -32, f by the operators hand, and, intermediate ly, it has a recess 34, in which is mounted apiv ote'd locking" dog 3 This dog is shown as normally pressed inwardly 'by a spring 37 secured to the handle. The nose 38 of the dog is adapted to engage with ratchet teeth or notches l0 formed on the front 25 in an are about the shank 23. end of the dog 36 is provided with a thumb piece 35 which. furnishes means by which it may he forced inwardly.

From the construction described, it will be seen that when the lever 30-is moved-upwardly about its pivot, it turns the 02111120 to spread the lower-ends of the jaws and thereby force inwardly the upper ends to clamp t-lmarticle or stock between them. A suitable stop ll limits the movement of the or convenient grippingplate The outer and 12. These and within the recess in an up and 4 cesses, are reinforced by additional plates cesses, less deep than the recesses of the cencross head above.

.also wear on lever into the releasing direction. The teeth 40 may be of ratchet form so that the dog nose will trail over them under spring pressure, in which case it is only necessary to pull up the lever to ell'ect the clamping, and to operate the dog by hand to release the lever, the latter being done by pr .ing inwardly with the thumb on the piece 35.

If the device is designed prii'narily for grasping pipe, or other rouniil, objects, there are preferably concave recesses in the faces of the jaw, as indicated at .30. These recesses are preferably serrated to form a good grip. in. addition to the main recesses, there are n'cferably smaller recesses 51 in the jaws, designed to receive comparatively small articles. The small recesses, when fully open, are designed to take as large an object as the large rec .ses when fully closed, so that the range ofthc vise is from the closed small recesses to the open large recesses. When fully closed, the upper portions of the jaws above and below the small recesses leome very close together, so that flat or other shaped objects, may be placed down direction between the jaws and clasped thereby.

The body portions of the two jaws are preferably plates, which, opposite the resides of the central portion.

on the opposite are designated 54- These additional plates and 55 in the drawing. They have recessed edges, which may be similar to those of the central portions, and are held on the central portion by dowel pins 57 and 58 carried thereby. These dowel pins properly position the reinforcing pieces, and the latter may be further secured by suitable screws 59. It is obvious that the reinforcii'ig strips may, if desired, have various shaped retra-l portions to provide ditl'erent engaging faces,- according to the character of the articles to be gripped. The reinforces may be case hardened to reduce wear, and are easily replaced when they have worn.

WVhen my vise is put inplace-on a plank or other support and the lever' dropped down to its normal depending piiisit-ion, the device is ready fen-receiving the stock. .By having no su 'ierstructare above the engaging portion of the jaws there is nothing in the way of the workmen working atthe bench or support, and the pipe or other stock may be placed in the jaws with the greatest ease. It is not necessary to slip the pipe endwise between the jaws, as is neces ary when one of tl1ejaws is supported from a As the stock is inserted in the jaws from above, it'results that any 'a recess between them, a pair of jaws pivintormediate portion may be inserted as easily as the end portion of the stock, and l the aws from sliding f the l stock is avoided. As soon as the stock is placed in the jaws, which, as explained, may be done very quickly and easily, the lever is drawn upwardly and the stock is antomatically clamped. Whenever it is desired to release the stock, it is simply neces sary to press inward the thumb piece on the locking dog, the binding pressure thereon being preferably relieved by a slight upward pull on the lever.

Having thus described my invention, what I claim is: r p

1. In a vise, the combination of a casing consisting of a body and cover plate leaving otally mounted within the recess and extending outside thereof, a double-faced cam within the recess between the jaws, said cam having a journal extending in opposite directions mounted in the frame and cover 5 plate, the journal mounted in the cover plate extending in front of the cover plate in the form of a non-circular shank, a lever on said shank adapted to move the cam to spread the inner ends of the jaws, and rack teeth on the cover plate and a cooperating dog mounted in a recess in the lever for holding the lever in the position it assumes when the jaws are in gripping action) 2. In a portable visea-the combination of a casing having an upwardly opening recess, said recess havingparallel sides, jaws pivoted within the recess when opening and having extensions fitting within the recess and guided by the parallel sides thereof, a cam within the recess between these extensions journaled in the casing and guided'by thesides of the recess, a lever outside of the casing for rotating the cam, and means for securing the casing to a su'table support.
