BENCH-VIS E'.
SPECIFICATION forming part of Letters Patent No. 511,429, dated. December 26, 1893.
Applicationfiletl March 27, 1tl93. Serial No. 467,728. (No model.)
To all whom it may concern:
Be it known that I, ALGERNON SIDNEY HUB- BELL, a citizen of the United States, residcause jaw b secured thereon, to travel to-' ing at Norwich, New London county, State of Connecticut, have invented certain new and useful Improvements in Bench-Vises, which improvements arefullyset forth and described in the following specification, reference being had to the accompanying sheet of drawings, in which Figure 1 is a side elevation and Fig. 2 a plan view of my device. Fig. 3 is a longitudinal sectional view taken on line m-m of Fig. 2. Fig. 4 is a plan view of the rearportion of the base-plate a showing in proper position thereon the cam-lever by means of which the movable jaw of my vise is operated, and Fig. 5 is a cross-sectional View of the clamping nut in, hereinafter described.
The object of my invention is to provide a simple vise, that may be cheaply produced, and which by reason of its peculiar construction, will have great gripping power.
The construction and operation of my device are substantially as followsz-a denotes a base-plate formed with a block b, the upper portion of which forms the stationary jaw 12' of my vise; said jaw being shown in Fig. 3 formed as a solid part of said plate and block. The block b is bored longitudinally to provide a bearing for a rod 0, said rod being designed to slide freely therein. The rod 0 bears upon one end (the left hand as illustrated in the drawings) the companion, or ad-v j ustable, jaw b It will now be readily seen, by reference to the drawings, that should jaws b'b be opened, any movement of rod 0 in the direction indicated by arrow 1 will ward jaw 19'. On plate a, somewhat in the rear of the block b, is located an upwardly projecting stud cl (Figs. 3 and 4), which forms the pivotal support on which swings the operating handle, or cam-lever, e of my vise. The inner end of said handle is bored to receive the stud d and has located on its upper side a boss g, said boss being shaped as a cam or eccentric (Fig. at), the same being preferably a solid part of the lever. (See Fig. 3.) Supported on the free end of'rod o is a loosely fitting nut It. Should the handle e be placed in the position shown in full lines in Figs. 1, 2 and 4 and the'nut adjusted on rod 0, until. its lower portion bears against the circumferential edge of eccentric g, any movement of the handle 6 in the direction of arrow 2 will cause said eccentric to force nut is gradually toward the direction indicated by arrow 1. lower portion of the nut, the latter is rocked and immediately binds the rod 0, and said rod and its connected jaw b are then drawn rearward with and by the nut. To insure the clamping, or binding, of the nut upon rod o I bevel the upper and lower portions of said hole upon opposite faces of said nut, so that the instant the nut is rocked the sides of said hole immediately wedge and bind upon rod 0.
To prevent the nut in from becoming displaced and lost when the vise is not in use, a small pin m is driven, or screwed, into the rod 0 near the free end of the latter.
In the drawings, my vise'is illustrated as supported upon a work bench or table at to which it may be secured by screws or bolts a passing through plate a. I
Assuming now that we have a vise of the construction described, that the various parts are prOperlyaSSembIedand that it is desired to use the same; the jaws are first opened to receive the object to be clamped (indicated by letters in Fig. 3) and the jaw b is then moved up against said object until both jaws bear against opposite sides thereof. The handle e having been previously placed in a position corresponding to that indicated by full lines in Fig. 2, the nut 70 is then adjusted upon rod 0 until the nut bears against eccentric g, asshown in dotted lines in Fig. 3. very slight movement of handle e will now force jaw 19 toward j aw b as above explained,
and thus clamp the object 3 firmly between 7 said jaws. The throw of eccentric g is so gradual that nut It; wedges firmly against its circumferential edge and prevents any liability of the handle a, and its connected eccentric, to jar loose; the same remaining in the position in which it is left until relieved by the operator.
My device as a whole having very few parts WVhen the eccentric engages the of extremely simple construction, ,may be loosely mounted upon said rod, and an eccenreadily assembled, cheaply produced, and trio adapted to engage and rock the said nut easily operated. substantially as and for the purpose specified.
