SPECIFICATIONforming part of Letters' .Patent No. 288,376, dated October 9, 1383.

` Application ined July 2, 1.333. (No moan.)

.To al whom it may concern.:

Be it known that l, CHARLES L. BELLMY, of Arlington, Hudson county, New Jersey, have invented certain new and useful Improvements in Clamps and lVises, of which the fol-A lowing is a specication.

My invention applies to the ordinarywoodworkers or cabinet makers bench clamp, which is axed to the front of the bench, and usually consists of two broad clamp-plates forced together by a screw, the upper edge of 4the jaws terminating on a level with the top My invention may therefore be briefly stated? to consist in the combination, with the bench clamp-jaws, of separable vise-jaws adapted to be amred to and removed from the'clampjaws, as occasion requires, and also in certain special constructions of the parts, as herein- In the annexed drawings, Figure l presents -a longitudinal section of my improved clamp and vise, andlFig. 2 isafront elevation thereof. Fig. 3 is a plan view, with the edge of the bench in section; and Fig. et is a plan of the clamp detached from" the bench and having the vise-jaws removed.

In Figs. 1 and 3, c indicates thefront plank or edge of the bench to which the benchclamp is afxed.

b c indicate the two jaws ofthe bench-clamp,4 which are formedas usual, of two broad castmetal plates of rectangular form, one of which, b, is fixed to the fr'ont of the'bench, while the other, c, is movable to or 'from the former, in

the usual manner. Thexedplate bis formed with two countersunk screw-holes at each end, to admit screws d d, (see Fig. 3,) whereby it is fastened to the bench, as usual. This fixed plate has also two tubular lugs .or sleeves, t', projecting backward therefrom, which admit two parallel gui de-rods, lac, which project from l the movable plate c, and thus support and guide the movable plate in its motions to or from the fixed plate. Through the center of both` plates the strong clamp-screw@ passes, its outer end being fastened in the hub of a hand-wheel, Z, which bears upon the front of the movable plate c, while the rim of the wheel stands sufficiently out from the plate to admit the ready v grasp of thethands for turningV the screw in or out, and thus opening or closing the clamp.

The inner end ofthe screw works through a nut, f, which is held between two projections, g g, on the back of the xed plate, which prevent it from turning, and as the nut is thus confined between said projections in a recess in the face of the bench when the plate is screwed up to the same, it follows that the turning of "the screw in the nut will cause the movable camp-plate to forcibly approach to or recede from the Iixed plate inthe ordinary manner. The Vtop edge of the plates b c are, Vas usual, placed on a level with the top of the bench, and the inner faces of the plates are planed smooth and level, so as to clamp a board orother wooden piece between them true and firm, in the usual manner of a wood-workers clamp.

Now, in order to enable metal-work or woodwork to beheld and worked in the clamp, I combine with the clamp-jaws a set of movable vise-jaws, mm', which may be affixed to or re- `movedfrom the clamp-jaws, as occasion requires, without affecting the rest of the clamp. These vise-jaws m m. are of the usual overhanging shape of vise-jaws, and are formed with a flat base which seats on the top edge of the clamp-plates, or rather on the top of a' semi-cylindrical swell orboss, t, formed on the top of the platea-over the clamp-screw e, which swells are bored with a simple round hole, t', forming sockets, in which a cylindricalstem, u, projecting from the base of the vise-jaws, is received andrmlysocketed, thus holding thc vise-jaw in a rigid manner to the clamp-jaw, yet admitting of its easy removal or fixation, as required.

The vise-jaw m', which is socketed in the fixed clamp -plate b, is prevented from turning in its Socket by means of a small pin, o, which projects from the socketi 11g-stem and tits into IOO a notch or groove, p, in thek top of the socket,

While the other jaw, m, on the movable clamp plate,V is provided with a movable lockingpin, o', which may be passed through a hole in the front of the socket into a coinciding hole in the stem of the vise-javv, so as to hold said j aw parallel With the Jiirst, and thus adapt the vise for holding parallel Work; Whereas, if it is desired to hold beveled work, it is only necessary to remove the locking-pin, which Will leave the jaw free to turn or swivel, and thus adapt itself to the bevel, as indicated in Fig. 3, thus providing both a parallel and a swiveling vise-j aw' by a very simple means.

It will be readily appreciated that by forming the vise-jaws with cylindrical stems and the clamp-plates With round bored sockets to receive them, not only is the attachment and removal of the vise-j aws rendered very simple and secure, but the construction is such as can be made cheaply and yet accurately, for byl ordinary operations of the machine shop it is very easy to bore the socket-holes t so that'l they shall be parallel with the clamping-faces of the .clampfplates, and it is also easy to turn the cylindrical stems of the vise-jaws so that they shallY he parallel with the clamping-faces of said jaws, so that accurate setting` or par allelism ofthe parts is thus insured Without expensive Work thereon, Which is an impor-I tant advantage. While, therefore, the afore!= said manner of engaging the vise-jaws with the clamp-jaws is very advantageous, and, forms one feature of my improvement, yet I; do not, of course, confine myself to this special, manner of engagement, for any suitable con-r struction of the vise-jaws so as to be capabler of being engaged With and disengaged fromy the clamp-plate may be adopted Without dei` parting from the main feature of my inventiom It may also have been noted that I employ in this clamp a hand-wheel, Z, for operatingf the screw, in lieu of the ordinary lever-handle,I which is much preferable, as it i's more Iconvenient in affording an effective grasp to the,V hand in any position, and in the fact that it is-A not liable to catch in the apron, as the leverhandle does; but I do not, of course, confine` myself to the use of the hand-wheel.

From what has been already set forth,it will therefore be obvious that a bench-clamp formed as described and equipped with the separable vise-jaws shown yforms a tool yof y much greater convenience and capacity for the shop than the common clamp, and at but a slight additional expense over the same,

thereby presenting a valuable improvementl in tools of this class.

What I claim is-' 1. A combined bench clamp and vise, formed by the combination, With the clamp-plates b c, adapted to receive movable vise-jaws, of the separable vise-j aws m m', adapted to be affixed j to or removed from the-upper edges of the clamp-plates, substantially as herein set forth.

2. The combination, with the clamp-plates b c of a bench-clamp, having sockets formed on or in the upper edge thereof, of the separable vise-j aws m m', having bases seated upon thel top edge of the plates, and projecting socketing-stems entering said sockets, substantial-7 ly as herein set forth.

8. In a combined bench clamp and vise s ubstantially such as set forth, the clamp-plates b c, formed With vertical cylindrical sockets t', parallel with the clamping-faces of the plates, in combination with the separable vise-jaws mm', formed with corresponding cylindrical.

shanks, u, parallel With their grasping-faces,to

enter said sockets, substantially as and for the purposeset forth.y p

4. The combination, in a clamp or vise such as set forth, with the clamp-plate b, nhaving a stantially'as and for the purpose set forth.
