Specification of Letters Patent.

' Patented Oct. 13, 1914.

Application filed February 10, 1913,seriaiNo. 747,214. neneweana l 28, 1914. Serial No. 842,812.

To all whom it may concern in the county of Summit, and State of Ohio, have invented certain new and useful Improvements in Bench-Vises, of which the 1 1 and lock ng of the parts is made efi'ective. A

following is a specification. a

This invention has reference to improvements in bench vises, and theinvention con.-,

sists in the construction and combination" of is a side elevation of one form of my new and original construction of vise, and Fig. 2 is a longitudinal sectional elevation thereof. Fig. 3 is a bottom view of said form of vise, and Fig. 4: is a cross section correspond ing in the main to line 55, Fig. 1. Fig. 5 is a side elevation of aslightly modified construction of vise partially shown in Fig. 4. 3

The entire structure as thus shown is made of drop forged steel and comprises the two jaw members 0 and d respectively, the guide bar Z2 and the keeper or yoke k.

The member 0 is the base member proper in both forms and in Figs. 1 and 2 is shown as having a flat circular seat support on a fixed base 6 and rotatably secured thereon by screw 3. The construction of the said base member also is original in this, that it is substantially elbow-shaped or right angled between its jaw and bottom portions and has a central bore axially at the base of the jaw the bar I) and its stem 3 are inserted and connected with the said screw. This being done the collar 5 is necessarily confined in the said slot and cannot escape.

The adaptation of the aws to the work is by sliding jaw (Z bodily on said bar I) and the keeper k serves as the medium for confining said jaw and holding it in working position I as it is moved here or there by hand. Thus, Be it known that I, JOHN R. Long}, a citi-- zen of the United States, residing at Akron,

in case the vise is to be tightened on an object, thejaw (Z will be followed by hand and very short movement of the bar 6 usually is sufficient for this purpose, and an equally short reverse movement ofth'e screw will loosen and release the objectin the vise because, as shown, boththe jaw cl andyoke 7c are usually locked together on the said bar by the screw 7 and must move together, nec essarily,' when the jaws are opened in this way. This manner of working is common, especially for doing standard work of a given size or kind and which avoidsrepositioning of the jawevery time the vise is opened. Otherwise the screw 7 may be loosened and the yoke and jaw d beseparatelymovable.

Incident to the foregoing I employ a dog 8 which is pivoted in its angle at 9 in the base a at itsouter 'end between two right angled projections 10 thereon and having its heel in friction engagement with the circular hub of the said base I). A screw 12 through the outer portion of said dog engages the bottom and end" of bar I) and forms a rest therefor, and a pin 13 through the said projections 10 limits the rearward movement of bar I). It follows that when a back pressure isexerted in clamping thejaws together it will manifest itself downward upon the outer end of bar I) uponscrew 13 and the dog 8 will lock on the hub of base. b jaccordingly and prevent rotation of the vise. But when thejaws are loose the vise is free to be turned onits base. Respecting thesaid parts I) and cl, it is to be observed, also, that both have flat straight meeting edges, and that the-jaw d has side earsll at its front and bottom lapping upon the sides of body I) and serving to guide it thereon. Otherwise the yoke or keeper 7c servesas the confining as Then by turning fore be considered as having practically a wedge shape but the taper of one part runs toward the swell of the other, and the keeper Z4 is adapted to come into. locking position thereon in whatever position the jaw d may be placed as between the extremes of its ad justments on the bar b. v

The base or fixed member in Fig. 5 has i a straight botom 16 with side lugs or ears 17 adapted to be secured directly to a work bench or the like. The base Z2 has lugs 17 like part c and may be fixedin any suitable position for use. This provides :a guide and slide for the bar I) at its rear end while its front end is extended. through the bore of the base member 0 and slidable therein within limits. Both the upper and outer edge of the jaw member cl and the bottom edge of the bar I) are rounded or segmental in cross section.

Jaw and yoke K are preferably connected by a spring either a coiled spring 14: as in Fig. 1 or a bow spring as in Fig. 5, whereby when the yoke K is pushed back by hand-engagement with screw handle 7 the jaw cl is made to follow. The top edge 18 of the tapering extension or base of jaw 0 is preferably parallel with the inclined bottom edge of bar 6 so that the yoke K must in any event be limited in its separable movement frombar b.

What I claim is:

1'. In Vises, a base member constructed to i be fixed upon a suitable support and having a jaw, a bar having a body inclined from its rear toward its front end on its. under edge and having means to provide a limited adjustment thereof lengthwise on said member, a-secondary jaw having a shank inclined reversely to said bar on its upper edge and a yoke slidably mounted over said bar and said secondary member and flaring to conform to said member and said bar respectlvely.

'2. A vise having an elbow-shaped jaw member with a bore through the angle thereof-,a bar having a tapered body provided with a threaded stem projecting into said bore and a screw engaging said stem and adapted to adjust said bar longitudinally, in combination with adjustable means supporting the outer end of said bar and a movable jaw and yoke slidably mounted on said bar.

3. In Vises, a bottom jaw member and a base theref0r,-a tapered bar slidably mounted on said member and means to adjust the said bar longitudinally, in combination with a movable aw having a tapered shank and a yoke to operatively confine the same, a

pivoted dog at the rear of said bottom jaw 'member and means adapted to cause said .dog to lock on said base when pressure comes on said bar.

4-. A vise as described havmg two aw -members and a combined supporting and locking bar mounted on one of said members and having the other member slidable there on and a slidable yoke about said bar and the said jaw member mounted thereon.

5. A vise comprising a base member having a fixed jaw, a bar tapered in the direction of said fixed jaw and adjustably supported on said base member, a secondary jaw slidable on said bar, and a flaring yoke about said secondary member and said bar adapted to hold the said parts in working relations.

6. In Vises, a base jaw member constructed to be fixed to a suitable bottom support, a

tapered bar adapted to slide within limits on said base member and a secondary jaw having a tapered shank and seated on said bar, said bar and said secondary jaw having their tapers running in opposite directions, and a yoke about sald parts flared to conform to said tapers.

7. In Vises, a pair of jaw members and a bar and a yoke operatively connected therewith, the lower of said jaw members having a bore through the base of the jaw there on and provlded with a transverse slot at the outer portion of said bore and a confining 11p next in front of said slot and a screw "through said bore engaging in said bar and having a collar confined in said slot by said lip.

In testimony whereof I aflix my signature in presence of two witnesses.
