SPECIFICATION forming part of Letters Patent No. 793,796, dated July 4, 1905. Application iilcd May 29,1903. Serial No. 159,393.

Be it known that I, ERVIN SAMUEL Primu- MnR'r, a citizen ot'the United States, residing at Hanover, in the county of York and @tate of Pennsylvania, have invented a new and useu ful SawAttachment:torBench-Vises, ot' which the following is a speciiication.

The invention `relates to a saw attachment for bench-vises.,

lhe object of the present invention is to improve the construction of sawing attaclunents for bench-vises and to provide a simple, inexpensive, and eliicient metal-sawing device designed to be operated in connection with a bench-vise of the ordinary construction and adapted for cutting all kinds and sizes oi niaterial which may be held in a vise.

` A lurther object ot' the invention is to provide a metal-sawing` attachment zulapted to be readily applied to a vise and capable ol being quickly removed therefrom to permit the vise to be used as an ordinary bench-vise.

'lhe invention also has for its object to provide an attachment having' the saw-operating gearing at one side of the vise to be operated with the right hand and provided at the opposite side ot the vise with means for actuating the feeding mechanism, whereby the saw may be operated and ted simultaneously by a workman without changing his position in front oi the vise.

Furthermore, it is the object ol" the invention to enable the saw to operate close to one end of the jaws and to permit it to be moved backward beyond the same to enable the vise to be used without removing the attachment therefrom.

With these and other objects in view the invention consists :in the construction and novel combination and arrangement ot parts hereina'lter fully described, illustrated .in the accompanying drawings, and pointed out in the claims hereto appended, it being' understood that various changes in the form, proportion, size, and minor details oit construction within the scope ol the claims may be resorted to without departing' from the spirit or sacriicing` any of the advantages oi the invention.

ln the drawings, Figure l is a plan view of a metal-sawing attachment constructed in accordance with this inventlon and shown applied. to a vise. liig. 2 is a side elevation of the same. Fig. 3 a trent elevation, partly in section. lig. at is a transverse sectional, view illustrating the construction ot theleeding rneclnmism. Fig. 5 is a detail view illustrating the manner ot' pivoting the bracket and the means for tulcruming the lever. Fig. 6 is a detail view oll the inner end ot' the lever, illustrating the construction ior engagingI the rack ot' the slidable trame.4

Like numerals ot' reference (flesignatc corresponding parts in all the figures ot' the drawings.

l designates a bench-vise designed to be mounted on a bench by screws, bolts, or other suitable fastening devices and comprising a stationary frame or member 2, havingI a stationary jaw 3, and a movable member provided with an adjustable liaw it, cooperating with the stationary jaw. The adjustable jaw `ia operated by means of a screw 5, swivcled to the adjustable member and engaging a threaded opening or nut et' the stationary member iu the usual manner, and as this mechanism is olI the ordinary construction and does not constitute a portion of the present invention adetailed description and illustration is unnecessary.

The stationary member ot the vise is provided at the right-haiul side with a horizontal guide consistiugoi a dovetailed rib 6, beveled at its upper and lower edges, as clearly illustrated in Fig. 3 ot the drawings, and fitting in a dovetailed groove or way 7 ot a slidable trame 8, which carries a circular saw S). The slidable frame 8, which is adapted to be moved backwarril and forward, as hereinafter explained, is provided at the iront with transverse and longitudinal bearii'igs l() and ll, spaced apart, as shown, and receiving, respectively, a saw-arbor l2 and a drive-shaft 11.3. The circular saw, which may be made ol any desired construction, is secured to the inner end oit the saw-arbor, and it extends forwardly therefrom and is arranged adjacent to the right-hand ends oi? the jaws of the vise. The outer end ol the saw-arbor is provided with a bevel-pinion l5, which meshes with a similar bevel-pinion 16 of the inner end of the longitudinal shaft 13, whereby when the latter is rotated motion. will be communicated to the IOO saw-arbor for rotating the circular saw. The outer end of the long'itudinal shaft, whichis provided with a crank-handle 1T, is supported by a bearing 18'of an arm 19, which is formed integral with the front portion of the slidable frame and which extends forwardly and upwardly therefrom, as clearly shown in Fig. 2 of the drawings. rlhe crank-handle is located in advance of the vise and operates in a plane beyond the handle of the vise, which docs not interfere with the operation of the mechanism for actuating the circular saw. The frame S, which may be of any desired construction, is supported by transverse ribs 2() and 2l, and it is adapted to be readily removed from the vise by sliding it off the dovetailed rib or guide 6. By this construction the saw attachment may by quickly applied to and removed from the vise.

The slidable frame is provided at its inner side with a longitudinal rack consisting of a series of projecting teeth 22, forming' intervening recesses and adapted to be engaged by the inner end of a transverse lever 23, which extends from `the left-hand side of the vise and which is provided at that side with a suitable handle or grip 24, adapted to be grasped by the operator for feeding' the saw and for moving the same backward, as hereinafter explained. The grip or handle of the operatinglever 23 is located in convenient position to be grasped by the left hand of the operator without interfering with the use of the right hand for operating the crank-handle 17. The crank-handle and the operating-lever are simultaneously grasped by the operator, and the operation of the saw and the feeding thereof are simultaneous, and it is unnecessary to stop one operation in order to effect the other.

The operating-lever 23 is provided at its inner end with oppositely-disposed downwardlydiverging' teeth 25, adapted to alternately engage the rack and formed by recessing or cutting away the lower face of the latter and beveling' the upper and side faces thereof, as clearly illustrated in Fig. 6 of the drawings. The lever is tilted backwardly or forwardly to engage either of the teeth 25 with the rack of the slidable frame, and it is oscillated horizontally to move the frame backward or forward.

The lever is fulcrumed on the vise by means of a bracket 2G, provided with a depending' pivot 27, which is removably arranged in a vertical perforation or opening' of a lug 28, formed integral with the stationary member of the vise and extending from the left-hand side thereof, as clearly shown in Fig. 3 of the drawings. The bracket is provided directly above the pivot 27 with an oppositely-beveled portion 29, from the apex of which extends a vertical lug or projection 30, which is received within an opening' 3l of the lever. The lug is oblong in plan view, and the opening 3l, which conforms to the configuration vable therefrom at the end thereof.

of the lug at the lower face of the lever, has oppositely-beveled side walls and is iiared npwardly to permit the lever to rock o'r tilt on the oppositely-beveled or upwardly-taperedfulcrum portion 29 of the bracket, whereby either of the teeth 25 may be engaged with the rack. The bracket, which extends npward above the lever, is provided with a horizontal top portion 32, forming an approximately L-shaped arm and extending inwardly over the vise and terminating' directly above the lever 23 at a point adjacent to the inner end thereof. A coiled spring' 33 is interposed between the extremity of the arm 32 and the inner portion of the lever 23 for holding' either of the teeth 25 in engagement with the rack and for retaining the lever in operative position. The arm 32 is provided with a depending projection 34 for engaging the upper end of the spring, and the lever is provided with a similar projection 35, which extends upward .from a boss or enlargement 36 and which engages the lower end of the coiled spring. rlhe coiled spring is of sufficient length and strength to maintain the lever in engagement with the rack, and the lever is adapted to be readily rocked to engage either of its teeth with the rack, and it is capable of being oscillated to move the slidable frame backward or forward. By this construction the saw may be fed into the material with the desired rapidity, and it may be quickly withdrawn from the same when desired.

The slidable frame, which is detachably interlocked with the exterior guide, is remov- The bracket is located at the side of the vise opposite from the guide, and the feeding mechanisrn, which is mounted on the bracket, has a detachable engagement with the frame, so that it may be disconnected from the said frame to permit the latter to slide forwardly off the guide. Then the attachment is in place, the operating' crank-handle 17 is at the right-hand side of the vise and the feeding' mechanism is at the left-hand side thereof, so that both may be simultaneously operated. The attachment may be quickly removed from the vise to permit the latter to be used for ordinary purposes.

By mounting a light milling-cutter on the saw-arbor the attachment can be effectively used for light milling-work.
