VlSE-SLIDE.
Specification of Letters Patent.
Patented Jan. 2, 1906.
To all whom it may concern.-
Be it known that I, ELI M. WALKER,a citizen of the United States, residing at Meriden, county of New Haven, State of Connecticut, have invented a new and useful Vise-Slide, of which the following is a specification.
This invention relates to parallel-j aw vises of the type illustrated and describedin patent to Charles Parker, No. 11,137, dated June 20, 1854, and has for its object to provide a Vise-slide that is a combined movable 1' aw or chap and a tailpiece therefor which shall be so constructed as to enable it to stand the severest strains to which it can be ut in use without danger of breaking and without materially adding to the cost of production.
It has been a serious objection to viseslides as heretofore constructed that when used in heavy work and tightened up hard the jaw and tailpiece have proved unequal to the strain and have frequently broken,
' thereby ruining the vise or rendering it necessary to provide a new jaw and tailpiece. It has been attempted to overcome this objection by casting longitudinal rods into the slides. This, however, has failed to wholly overcome the difficulty, for the reason that the strengthening-bars, so called, have been wholly cast into the slide in locations other than in contact with the core. The result has been that in the operation of casting airbubbles,and not infrequently, considerable air-spaces have formed between the strengthening-bars and the metal of the slide or tailpiece, so that in practice the slides were rather weakened than strengthened by the casting in of the so called strengthening bars or rods.
In order to wholly overcome the difficulty above stated and provide a vise-slide which shall be thoroughly reliable under all the ordinary and even extraordinary conditions of use and which may be safely applied to the heaviest kinds of work within its scope without danger of breaking, I have devised a viseslide having a longitudinal strengtheningbar extending therethrough, which is partially cast into the metal of the slide and is provided with an exposed face which forms a portion of the wall of the longitudinal opening in the slide. I thus secure a perfectly homogeneous casting Without air spaces or bubbles, secure the full strength of the metal of the slide, and render the slide practically non-breakable in use through the reinforcement given to it by the strengthening-bar.
In the accompanying drawings, forming part of this specification, Figure 1 is a front end elevation of my novel vise-slide ready for assembling; Fig. 2, a longitudinal section on the line 2 2 in Fig. 3, and Fig. 3 is a transverse section on the line 3 3 in Fig. 2.
10 denotes the jaw, and 11 the tailpiece, which is provided with the usual longitudinal opening 12, to receive the operatingscrew, and in its under side with the usual slot 13. It will of course be obvious that the special design or configuration of the j aw and tailpiece are wholly unimportant, so far as the present invention is concerned. The essential feature of my novel vise-slide is the strengthening bar 14, which I preferably make angular in cross-section and of greater height than width in order to give to the viseslide ample strength just where it is needed to resist the stains of use. In casting the strengthening-bar is so placed in the mold, next to the core which forms the longitudinal opening 12, that when 'the core is removed the lower side of the bar will form a portion of the wall of said longitudinal opening. The effect of this arrangement is to prevent the formation of airholes or air spaces between the strengtheningbar and the metal of the slideth1s for the reason that the strengtheningbar is only partially inclosed in the molten metal and permits the casting to be vented at and by means of the core. I find in practice that perfect cohesion takes place between the strengthening bar and the metal of the slide, the bar being perfectly embedded in the slide and there being no air-holes or airspaces between them, because the gases developed by the welding of the molten metal to the steel bar can pass out into or through the core. The slide thus has imparted to it a greater degree of strength than is found in any vise-slides heretofore placed upon the market.
Having thus described my invention, I claim- A vise-slide having a longitudinal opening therethrough and a strengthening bar ern- In testimony whereof I affix my signature bedded in the slide above and having an eX- in presence of two witnesses. I posed lower edge which forms a portion of ELI M W ALKER the Wall of the longitudinal opening, the said 5 bar extending under the jaw portion of the WVitnesses:
slide whereby the slide is reinforced through- J AS. R. SLOANE, out the portion subjected to strain. J. H. OROsSLEY.
