MQRTlMER QLEWIS, "OF NEW YORK, N. Y;

i' BENCH ySE.

SPECIFICATON forniing part of-'Iletters l 'atent No, eo5,1o6, dated J'une 7, 1898.'

-' Application filed December 24,1897. %eria1No.663,295. ero model.)

Tool/Z& whom 't may concern:

Be it known that I, MORTIMER G. LEwIs, a citizen of the United States, and a resident of New York, in the County and- State of New York, have invented certain new' and useful Improvements in Bench Vises of which' the following is a specification.

My invention has relation to `bench-vises, and especially to those portions thereof which are concerned with'the movements 'of and the sustaining of the movable head with respect to the other or stationary head.`

The principal object of my invention is to supply the vise with a slidingbar which shall be light and yet abundantly strong, which shall be capable of withstandin g the injurious eifects of hammering or pounding thereon, which shall afford peeuliar conveniences in the matter of oiling the screw,"and which shall protect the same against accumulation of foreign substances thereon; and a subordinate object is the simplification and improvement of theconstruction, whereby the nut may be easily formed or placed and afford' ample strength and security at this part.

To accomplish 'all ot' the above and to secure other and furth'eradvantagesin the matters" of Construction, operation, and use, myimprovements involve certain novel and useful arrangements or combinations of parts and peculiartiesof Construction, as willbe herein' first fully dscribed, and then pointed out in the claimsk t In the accompanying drawings, forming' part of this specification', Figure l -is a verti cal section and elevation upon a plane through the stationary `vise-head,`as on line a; oc of Fig. 2 and looking in the direction of the arrow;

ments is preferably made of steel, and it is united with the'front jaw in some substantial manner, as by casting the jaw upon it.

The sliding bar as heretofore constructed .either protects the screw to such eXtent that it is impossible to oil the latterwithout removing the bar bodily from the stationary head or else it leaves the screw exposed to the collection thereon of clippings orfilings which interfere With its proper working; and in such forms as sufficentlyprotect or cover the screw the projecting portion of the bar is commonly used for an anvil or support on which hammering is done, to the detriment of the bar. I therefore make the bar of substantially rectangular section on the exterior, as indicated, the .upright side a being full, the base portion b extending across the slot through the head B, the top c fiat, and I provide the flat top with a flange d, extending throughout the length of the top, but reaching down only below the upper surface of the screw. This flange strengthens the top to such extent that it may be hammered upon, same as in the ordinary forms, but without injury, and itenables me to make the bar of much lighter metal than'the former constructions, while retaining all'. necessary strength to withstand the cross-strains consequent upon the clamping action or the hammering upon work which maybe held' by the vise-jaws.

. As the vise-bar'is moved back and forth the fianged'bears' against the side wall of the rectangular opening in the rearvise-head, and

thus prevents wearing or'cutting-into that wallyaswouldf occ'ur withoutithe flange, es-

-jpecially when the bar is made of thin and light parts, *as it is my purpose to make it. The greater portion of the screw being exposed on the side, as shown, the top of the screw may be easily reached with the nozzle of an oil-can and oil projected thereon without disturbing'any of the parts. The upper part of the screw being entirely cvered, it is protected against lodgment of any foreign substances upon`it, as will be understood.

The nut Dis affixed to or formed with the inner side of the stationary head after any approved manner of construction. It may be thus easily tapped or seated, being easily reached from the exterior and from either the backor front of the stationary head. The

lower portion b of the har slides under the nnt, and the 'lange (l slides over it, so that the size of the nut is only limited in a vertical direction. The nut may be earried forward or baekward as far as may be desired, or it may be braced forward or baekward to any desirable extent, as indicated by the dotted lines at e e in Fig. 2.

The parts being construeted and arranged substantially in aeeordanee with the foregoing explanations will be found to answer all the requirements in econony of metal, strength to resist hammering and strains, protection from obstructing the screw, and con- Venienee in oiling, as above indieated.

Having now fnlly described my invention, what I claim as new herein, and desire to secure by Letters Patent, is-

1. In a hench-viso, the sliding bar having the flat top and bottom parts united on one side by the upright piece, the top being provided with a fiange extending down part way on the other side and hearing against the adjacent vertical wall of the opening in the rear Vise -head, substantially as shown and described.

2. In a bench-Vise, the combination of the screw, the sliding bar having a flange on one side, and the nut located within the stationary head and at the side thereof, said nut being braeed or extended in the direction of the length of the bar, substantially as shown and described.

Signed at New York, in the County and State of New York, this 21st day of December, A. D. 1897.
