Specification of Letters fPatent.

Patented Mar. 2, 1920.

To all whom it may concern:

Be it known that I, FRANK O. HOAGLAND, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield `and State of Connecticut, have invented certain new and useful Improvements in Vises, of

which the following is a specification.

My invention relates to new and useful improvements in vises of the swivel type, adapted to be secured to a bench andadjusted to different positions for holding work therein.

The object of the invention is to provide an improved construction of vise wherein the front jaw is stationary and the rear jaw is made to move to and from the work and front jaw. To provide a clamping screw whose opposite end portions are supported in the flXed jaw member, and whose intermediate portion is in engagement with the movable or rear jaw in a way to operate the same, thereby providing three bearings or supports for the screw in a manner to form a firm engagement of the same with the coacting parts. Further to construct the vise so that the screw and connected parts contained within the front portion of the vise will be covered and inclosed, and finally to include a saddle having longitudinal ways and between which the movable rear jaw is slidably mounted.

With these and other objects in view, the

Vinvention comprises novel features of construction and combination of parts shown upon the accompanying two sheets of drawings forming a part of this specification, and upon which similar characters of reference denote like or corresponding arts throughout the several gures, an of which:

Figure 1 shows a top plan view of my improved form of vise complete.

Fig. 2shows a central vertical longitudinal section of the same taken on line --m of Fig. 1. f

Fig. 3 is a front end view, and

Fig. 4 shows a cross section taken on line 1 y of Fig. 1.

,Referring in detail to the characters of reference marked upon the drawings, 6 indicates a bed which is provided with pockets 7 to receive screw bolts for securing the vise to a bench. This bed is provided with a circular hub portion 8 that fits into the round pocket 9 in the under side of the saddle l0 which is adjustably rpositioned thereon. A n annular shouldered slot` 11 is formed in the bed to receive the head of the bolts 12,` carried in the saddle, and which are provided with nuts 13 for securing the sad dle to the hed.

The saddle is of an elongated shape and has a longitudinal way 14 formed in the central portion of its top side' to receive the base 15 of the movable rear jaw 16, and in addition is provided with longitudinal grooves 17 positioned in the opposite side walls of the pocket 14 to receive the end of the plates 18 secured to the opposite side portions of the base of the movable jaw by means of screws 19 whereby the said jaw is held down against the saddle. The front end portion of the base of the movable jaw is provided with a bearing 2O in which the threaded bushing 21 is positioned to be engaged by the clamping screw 22.

The front jaw, which I have designated as 23 and which I have already referred to as being a fixed jaw, is secured to the saddle by means of screws 24 and 27 and is further provided with ribs 25 that are positioned in the cross pockets 26 formed in the two longitudinal top surfaces of the side portions of the saddle to better hold the fixed jaw in position and to relieve the strain from the screws 24 and 27. This fixed jaw member together with its extended hood portion 28 thus bridges the longitudinal way 14 and the base 15 of the movable jaw 16, as well as the clamping screw 22 before mentioned. An apron 29 is formed integral with and disposed downwardly at a right angle from the top surface of the hood in a way to cover the front end of the way 14 and to provide a front bearing for the clamping screw 22.

The clamping screw, as will be noted, is provided with three points of engagement for the purpose of affording a more reliable operation and a more rigid engagement of the screw with both the fixed and movable jaw members and, as will be further noted, has two bearings in the Xed member and one in the movable member. In addition to the bearings 30 in the apron for the forward end of the clamping screw I also provide a bearing 31 in the back of the jaw for the inner end 32 of the screw, and I also position a hardened steel bushing 33 between this end of the screw and the jaw so as to prevent? wear of the jaw member, whereby a more permanent and rigid bearing for the screw is obtained. The bushing 2l carried by the base l5 of the movable jaw member thus serves to operate on the intermediate portion of the screw and between its two bearings as aforesaid and is thus rigidly supported so as to avoid any tendency of the screw to spring or the jaws to glve. y

The construction further serves to provide a direct connection between the fixed jaw and the movable jaw and includes spe- Lacasse what I claim and desire to secure by Letters Patent, is

1. In a vise of the class described, the combination of a base member, a jaw liXed thereto, a hood carried by said base and spaced therefrom, an apron depending from said hood and terminating adjacent the base member, a movable jaw, a slide carrying the movable jaw and mounted on the base member, an operating screw having a thrust bearing in said xed jaw, journaled in said apron and operatively associated with said jaw slide.

2. The structure called for by claim 1, characterized in that a threaded bushing is carried by the inner end of the slide with the operating screw extending therethrough.

Signed at Bridgeport in the county of Fairfield and State of Connecticut this 27 day of March, A. D. 1919.
