VISE.

Application filed September 20, 1926. Serial No. 186,558.

n A further object is to provide a vise which obviates the use of the usual screw threaded shaft carrying the movable jaw in order to adjust the same with respect to the stationary jaw, thus saving considerable time and 17% labor in the adjustment of the vise.

A further object is to provide a vise of the above mentioned character which is simple in construction, inexpensive, strong, and durable and further well adapted to the '2 purpose for which it is designed.

Other objects and advantages of the invention will become apparent during the course of the following descriptiontaken in connection with the accompanying drawing.

part of this application and in which like numerals designate like parts throughout the several views: V

Figure 1 is a longitudinal sectional view through the vise'embodying my invention.

Figure 2 is a top plan View thereof, the cover or top of the casing being removed.

Figure 3 is a sectional view taken approximately on line 83of Figure 1.

Figure & is a bottom plan view of movable cover or top, and

Figure 5 is a fragn'ientary detail showing the locking pawl in its dropped position of the shaft.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally a substantially rectangular shaped casing, which includes the sides 2 and the forward'and rear ends 3 and 1 respectively. Formed on the upper portion of the forward end 8 and extending above the top of the casing is the stationary jaw 5.

the rep to A cover or top plate 6 is adapted to be ,secured on the upper edges of the side 2 of the casing 1, suitable openings 7 being formed in the cover or top plate 6 adjacent the longitudinal side edges thereof for c0- operation with similar openings 8 formed In the accompanying drawing forming a in theupper edgeof the side members 2 for receiving suitable fastening" means; The forward end of the cover is cut out as 'indicated at 9to accommodate the portion-of thefstationary jaw which extends above the top of the casing. A series of transversely extending ratchet teeth 10 formed on the bottom of the cover or top plate 6cin the central portion thereof and the purpose of these ratchet teeth will described. a v

Suitable guides 11 are formed on the inner faces ofthe sides to the casing 1 adj-a cent the upper edges thereof said guide members extending longitudinally "of the casing. Additional longitudinally extending guides 12 are formed on the inner opposed faces of the sides 2, adjacent the bottom edges thereof, and as is more clearly illustrated in Figure 3, the lower guides extend inwardly further than the upper guides. i

Adapted for slidable movement within the'casin'g 1 is a substantially rectangular shaped block-13, the bottom of said block is slidable along the upper facesof the lower guides 12, and is of such width as to be disposed between the guides 11. A rib 14 is formed on the bottom of the block 13, and

is adapted to extend downwardly between the lowerguides 12, as lsinore clearly illustrated in Figure 3. In this manner, the

block 13willbe adapted to slide longitudinally within the casing and freely between the guide members provided therefor.

Extending through theforward end 3 of the casing, and having its inner endextending through the passage 13 formed in the 'upper portion of the slidable block 13, is

The inner end por- 9 the rotatable shaft 15. v tion of the passage 13 is threaded for cooperation with threaded portion 15 of the shaft 15, in securing fine or close adjustment of the jaws. The outer end of the rotatable shaft 15 extends through the relatively thick plate member 17 on the upper,

hereinafter be more fully portionof which is formed the jaw 18 which I jaw is movable with respectto the stationary jaw 5 and is further adapted for cooperation therewith. A handle 19 is-secured on the outer end of theshaft and this handle engages the outer faceof the plate 17,a cotter'pin 2O,'extending through the shaft adjacent the inner face of the plate 17 so that the movable jawwill be carried by the shaft and will slide simultaneously therewith, as will be hereinafter more clearly described.

In order that the plate-like member 17 and the jaw 18 carried thereby maybis-mainends thereof estendingginto the bottonrportion ofthe member 17. These rodsteXtend through the lower portions of the forward ends 3 of the casing 1 and are slidable in suitable longitudinally extending openings providedtherefor in the lowerguides 12 which are formed on the innerpfaces of the respective sides of the casing in the manner as clearlyillustrated in Figures 1 and 3. a A substantially rectangular shaped ,recess 22 is formed in the top of the block 13, and this recess communicates with the horizontally disposodopening formed in the block for receiving the shaft. 15, Adapted for vertical slidable movement in therecess 22 is thepawl 23, the same beingprovided with the teeth 24 inv the upper face thereof for cooperation with the ratchet teeth formed on the-bottom of the cove-ror top plate 6. A notch 25 is formed in the bottom of the pawl 23, and the purpose thereof will be presently apparent.

The :portion of the rotatable. shaft whichis disposed below the recess 22 is cut awayas illustratedat 26 and 27 respectively,

whereby aprojection 2st: formed in the cavity provided in the shaft. 15, and this projection 28 is adapted for cooperation with the notch formed in the bottom of.

the vertically slidable pawl 23, in the manner as clearlyshown in Figure 5..

The inneropposed faces of the coacting jaws are provided with the coacting curved serrated portions 29, and are arranged vertically 1n order that the pipe or other cylindrical object may be clamped in'the. vise in ing the shaft 15 in one direction throughthe 7 medium of the handle 19 so that the projection 28 is moved into alinement'with the recess or notch25 formed in the bottom of the pawl 23 and to further bringthe out out portions 26 and 27 of the shaft 15 into registry with the recess 22 so that the pawl 23 will by gravity move downwardly in the recess 22 and enter the cut out portions 26 more clearly in Figure 5. The lug 16 carried by the inner end of the shaft 15 will engage withthestop 16 arranged on the inner end of the block in limiting the sliding movement of the shaft so that the cut out portion or notch 25 will register with the projection 28. The handle 19 is pulled outwardly, causing the block 13 and the nte-nkememtem'r which carries the jaw 18 to slide forwardly simultaneously.

After the jaws have been opened to the properdistance to facilitate the insertion of the member which is to be clamped between the jaws, theshaft 15 is rotated in the reverse direction whereupon the projection 28 is moved out of engagement with. the notch 25, andthe out out portions 26 and 27 are also moved out of almement with respect to the recess that the pawl 23 will jaws and there will be no possibility of the movable j aw 18 being accidentally loosened.

The provision of a vise of the above mentioned character will obviate the necessity of having to provide the usual screw threaded shaft wlnci carried the movable aw and 1 thereby will save considerable time and labor in adjusting the jaws with respect to each other. Furthermore, a device of the-above mentioned character will securely hold a pipe orother object in a tightly clamped position in the vise in order that the proper work may be pei-formed on such object.

This vise may be readily and easily adjusted, and will furthermore be strong and durable.

, TVhile'I have shown the preferred embodiment of my invention it is to'be understood that minorlchanges in the size, shape, and arrangement of parts may be resorted to without departing from the spirit of scope of the invention;
