SPECIFICATION forming partk of Letters PatentNo. 540,413, dated J une 4, 1895.

Application filed February 15, 1895. Serial No. 538,576. (No model.)

To @ZZ whom it may concern.-

Be it known that I, ABRAHAM VANDERBEEK,

a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful ImprovementsVV in Vises, of which the following is a specification.

This invention relates to vises of that class commonly known as planervises; the object of my invention being, primarily, to furnish an improved vise of this class having a pair of working-grasping jaws, one of which is adapted for movement toward and from the other, and to provide, in connection with the movablejaw, an improved vadjusting-andlocking device adapted for exerting a downwardly-inclined moving force'upon said mov' able-jaw in the direction of the advancing movement thereof, thereby positively holding the jaw and work against llifting movement, relatively to the bed.

Another object of the invention isto f-urnish a planer-vise of such construction and organization that the movable jaw thereof may have a limited amount of transverse and oscillatory movement, relativelyto the opposing jaw, to adapt the vise vto irregular work, and may also be quickly shifted for-ward or backward, to adapt the vise for small or large work, without manipulation of the adjustingand-clamping device, other than Ylooseningl the same.

In the drawings accompanyingand forming a part of the specification, Figure ll is a plan view of a planer-vise embodying my present invention, said ligure showing in dotted lines an oblique position of the movable jaw. Fig.

taken in line a a, Fig. l, and showing in dot ted lines a piece of work between the two clamping-jaws of the vise,land showing the parts of the vise in the position they occupy just preparatory to the clamping adjustment ot' the movable jaw. Fig. 3 isa similar longitudinal section of a portion of the vise, showing the movable jaw and the clamping device in connection therewith in the positions they occupy when said jaw is tightly clamped against movement. Fig. 4 is a similar view of the parts shown in Fig. 3, showing the movable jaw released from its clamped position and the clamping device in position to permit free sliding movement of said jaw. Fig. 5 is a cross-sectional view of the vise, taken in line l) b, Fig. 3, looking in thedirection of the arrow in said figure.

Like characters represent like parts in all the figures of the drawings.

In the preferred embodiment of my invention, herein shown and descrbed, the vise comprises, in part, a longitudinally-recessed bed or frame B, having a rack 2 upon the under side thereof, adjacent to the longitudinal recess, and having a fixed-jaw J at one end thereof; a movable jaw J, supported upon said bed; a rack-block R, supported below and adapted for engaging the rack 2; a clampt ing bolt C, projected through the movablejaw J, and the bed B, at an inclination to the rplane of movement of said jaw, and pivotallyconnected at the lower end thereof to said rack-block R, and means carried by said bolt in position and adapted for tightly clamping the parts in adjusted position, all of which will be hereinafter fully described.

The bed B, and the fixed jaw J at one end of said bed, will preferably be formed integral with one another, as illustrated in the draw,- ings, although it will be obvious that thjaw J, and bed B, might be separately constructed and secured together 'in any suitably manner. The bed B, which may be of any suitable general conformatiomis herein shown, in the Ynature of a rectangular-block longitudinallychanneled at its under side, as shown at 3, 3 and 3, to form longitudinal flanges 4 and 4', on each side the longitudinal center of said bed, which anges, and the channel 3, intermediate thereto, constitute a guideway for the rack-block R, which is supported 'in said channel between said tlangesi Formed through the upper wall 5 of the bed B, preferably mid- Way between the two flanges 4. and 4', and

communicating with the channel 3, is anupper wall of the bed, is herein shown in the nature of an oblong rectangular-block having the perpendicular work-grasping face 7, horizontal upper and lower faces 8 and 8',and an inclined or oblique rear bearing-face 9. Formed in this inclined movable face of the jaw, is a spheriform-socket 10, which constitutes a seat for a correspondingly spheroidal bearingblock or washer 12, and formed through the lower face 8' of the movable-jaw J', and communicating at. its upper end with the Spheriform-socket 10, is a bolt-receiving opening 13, which, is preferably conical in form, it being enlarged or laterally-elongated, at the lower end thereof, to permit a limited play of the holding-down bolt or clampingbolt C, which extends through said opening, and also permits the jaw J' to swing sidewise in a horizontal plane, and through a model ate arc, around said bolt, to thereby adapt the jaw for engaging a piece of work of irregular contour.

As a convenient means for facilitating the quick adjustment of the movable jaw J', relatively to the fixed jaw J, so as to accommodate said jaws to work of varying sizes, at the least possible expense of time, I have pro vided in connection with the movable-jaw and bed, an oscillatory clamping-device, designated in a general way by D, which is adapted to be quickly thrown into operative engagement with the bed, when itis desired to tightly clamp the movable-jaw `against a piece of work (as W), and is adapted to be quickly thrown ont of engagement with said bed, when it is desired to open or close the jaws of the vise, preparatory to clamping them against a piece of work. This clamping-device for the movable-jaw J', in the form thereof herein shown, consists of the holdingdown bolt or clam ping-bolt C, extending diagonally through the recess 6 in the bed B, and throughthe bolt-receiving opening 13 in the movable jaw J'; a rack-block R, pivotallycarried at the lower end of the inclined bolt C, which block is supported for traversing movement in the channel 3, between the guide-Hanges 4 and and a' below the rack 2, and has a rack 14, at the upper face thereof, the teeth of which are adapted for engaging the teeth of the rack 2 of the bed; a spheroidal bearing-block 12, carried upon the upper screw-threaded end 15 of the bolt C, and normally bearing against the corresponding spheriform wall of the socket 10, and a clamping-nut or thumb-nut 1G, adjustably iitted to the eXtreme outer end of the clamping-bolt C, as will be readily understood by reference to Figs. 2, 3 and 4, of the drawings. In the preferred form thereof herein shown, the center of curvature or axis of the spheroidal bearing-block and the spheriform-socket in which said bearing-block is normally seated, is located, during the clamping action of the bolt C, at a point approximately in alignment with the upper plane of the movable jaw J, or at a point considerably above a horizontal line drawn midway between the upper and lower faces of said jaw, so that, when clamping a piece of work between the jaws J and J', the pressure against the upper edge of the working face 7 of the sliding-jaw J', is taken directly by the clampingbolt C, and does not tend to lift thegjaw. It will also be seen, by reference to Fig. 2, that pressure exerted upon the working face of the movablejaw J' at any point below the upper edge of said working face, will, owing to the location of the axis of the spheroidal bearing-block above the point by which pressure is exerted, tend to directly hold down the working end of said jaw, while the rearward end of said jaw will be held down by the downward stress of the bolt C.

For normally holding the rack-block R, in engagement with the rack 2 of the bed B, some suitable spring will preferably be provided. designated by s, is shown secured at one end to the lower face of the block by means of a screw 18, and has its free end bearing upon a longitudinally-disposed bar 19, which is fixed at opposite ends thereof to the under side of the bed B, as shown in Figs. 2 and 5. This construction and arrangement allow a free slidingmovement of the rack-block when thrown ont of engagement with the rack 2 of the bed, and bar 19, and willalso prevent the rack-block from dropping out of place, should the spring s, be broken, and also limits the releasing movement of said rack-block.

As a convenient means for depressing the lower end of the clamping-bolt to throw the rack-block R out of engagement with the rack 2 of the bed l5, forthe purpose of quickly shifting the movable-jaw toward or from the fixed-jaw J, I have provided in connection with the movable jaw, a pressure-pin, or plunger 20, which is seated for vertical movement in a vertical recess in said jaw J' with its lower end projected into the bolt receiving recess 13, in position for bearing against a shoulder2l, formed on the clamping-bolt C. In practice, this shoulder 21, will preferably be formed by notching the upper face of the bolt C, as clearly shown in Figs. 2, 3 and 4, of the drawings. The depressing-pin or plunger20, will preferably be shouldered at the upper ends thereof, and the recess in which said plunger works, will have an internal abutment to limit the depressing movement of said pin.

In practice, when it is desired to throw the rack-block R, out of engagement with the rack 2 of the bed, to effect a quick shifting movement of the movable jaw J', it is simply necessary to loosen the clamping-nut 1G, and bear down upon the depressingfpin 20, which will depress the lower end of the bolt C, and disengage the rack-block R, from the rack 2, as shown at Fig. LLof the drawings. In some cases, however, especially when a thumb-nut of convenient size is used on a bolt, said bolt may be depressed or tipped downwardly by In the present instance, this spring move forward with the jaw, while the lower lIO end of said bolt remains at a fixed point, relatively to the bed, by reason of its connection with the rack-block, which block,during the clamping operation, is in fixed engagement with the rack 2 of the bed of the vise. The advancing movement of the jaw, through the medium of the thumb-nut 16, and bearingblock l2, owing to the inclined position of the bolt, not only changes the inclination of the bol t, relatively to the working face of the jaw, but lifts the projecting end thereof, so that the nut, when screwed down, will traverse a greater distance than will thejaw J, proportionate to the hypotenuse and the vertical side of the triangle. This increase of movement of the thumb-nut on the bolt, relatively to the movement of the jaw on the bed, has the effect of-multiplying the power of the nut for the clamping of a piece of work 'between the jaws of the vise, so -that a eoarser and4 stronger thread may be used on the bolt, than would otherwise be the case and main-tain a given amount of power. The relation yof the shoulder 2l, and the bolt, to the depressingpinQO, will be such as t'o positively insure a bearing-contact between said pin and shoulder, when the rack-block is in engagement with the rack 2 of the bed.

By the construction and organization of clamping means herein shown and described, it will be seen that a turning of the thumbnutdownward upon the bolt C to effect a clamping action of the jaw J', will draw the rack-block upward and backwardandv into locked engagement with the rack 2, and that the movable-jaw J will be. simultaneously forced downward and forward, in opposition to the locking movement of the rack-block; the backward movement of the rack-block being, of course, relatively small, as compared with the forward movement of the jaw J', as will'be readily understood by a comparison of the figures of thedrawings.
