GEORGE WASHINGTONRUSIL'OF NEW YORK, N. Y.

SAW-CLAMP.

Be it known that I, GEORGE WAsnINo'roN Email, a citizen of the United States, resid- *ing at NewYork, in the county and State of i and simple New York, have invented a new and useful Im rovement in Saw-Clamps, of which the.

fol owing is a specification.

My present invention relatesto an unprovement in clamps especially ada ted for use in holding saws to facilitate the s arpening and setting of the teeth, and the object thereof is to (provide a strong, durable, chea evice, capable of read attae ment to a support and equally capa le of ad-,

ustrnent to securely position to be operated upon.

, A further object of the'invention is to provide an arrangement in which saw-blades of various thicknesses ma beheld without necessitating aspecial a ju'stment, and still a further object is to provide for a quick and ready adjustment forclamping the blade in position and to facilitate its removal from or its adjustment within'the clamp. a

With these briefly statedobjects'in' view, the invention, also comprises certain details of construction and peculiar combination and arrangement of parts as will be fully set forth in thefollowing specification and pointed out in the elaims,-reference beinghad to the drawings, in which Figure 1 is an elevation of my improvement showing a saw held therein. Fig. 2 is a detail perspective view of the clanjp. Fig. 3 is a similar view looking at. the opposite side to that shown in Fi 2. Fig. 4 is an end view of the clamp sowing it held upon a suitable su port and a saw-blade locked in position, 1 1g. 5 is a similar view showing.- the clamping-j aw open and the saw-blade removed. Fig. 6 is a detail perspective view of the frame of the supporting bracket, and, Fig. 6 is a detail view of the anel carried by the frame. Fig. 7 isadetai perspective View of the clamping lever, and, Fig. 7 is a detail view of the panel carried b 'the lever, and, Fig. 8 is a detail plan view 0 one end of the clamp;

fact any suitable support.

The bracket 1), is constructed of a single strand of stout spring steel wire which is bent intermediate its ends at the points D, to provide a straight section D to which the panel C, is. connected by means of staples as shown most clearly in Fig. 3 ofthe draw .ing. From the points D, each end is bent upwardly in'a semi-circular form as at D, to providexarch members, and at the extreme outer ends of the-arches, the wire is twisted into eyes D which provide journal bearings for the movable section or jaw as will be explained later on.

From the points forming the eyes, the ends are extended backwardly parallel and imeaeh end is continued ast the ooints D, in a vertical direction as sl iown at to a point D", from which the ends are bent upwardly as atD, parallel with the sectionD, to

' ointsD, thence over as at D, to the point about midway between the arallel nected to a bench, chair-back, board, and in mediately adjacent the arch members, and

the stationary section slipping from itssupport, and in order that the clam may be readily attached to the support, I end the extreme ends outwardly as shown most clearly in Fig. 6. of the drawing.

In practice, I also employ staples (.1 at oints D to insure a firm attachment for t e anel,.and itwill of course, be understood t at the staples are clenched at their ends to prevent them being pulled out.

The movable clamping section or jaw B, comprises a panel G,'of substantially even length as the panel C, and an o crating lever handle H, and the lever hand e is also constructed of a single strand or a loop of steel spring wire which is bent intermediate its ends at the points H, H, to provide a longi-' tudinal section II, to which the panel G, is connected by means of sta les G, and in order to prevent the strain eing applied to the 'sta les, I provide the panel G, with a longitur inal groove G in which the section H of the handle is held. From the points H, the wire is bent outwardly and downwardly as at H, to points H from which the wire is extended outwardly as at H in arallel direction with respect to the section thus providing crank arms H and shaft portions H which latter are journaled in the eyes D, of the bracket D. From the outer ends of the shafts, the wire is bent,

downwardly as at H, to point H from which extends the remaining portion of the wire to provide a handle-section H After the parts have been assembled as shown in Figs. 1 to 5 inclusive, the device is ready for use and by inserting the U-shaped' members. over a sup ort and drawing the lever-handle outward y as shown in Fig. 5,

- the panel G of the clamping-jaw is moved H, or above a horizonta line which provides a locking device that will prevent the accidental movement of the movable jaw, and is held in this position by reason of the arch members being pushed or sprung out of their normal position.

-It will thus be-seen that the arch members serve the double purpose of providing a journal for themova le jaw and also a spring 'c'la" p which permits of the ready the purpose for which it is emp Having thus fully described my invention,

accommodation of. saw-blades of various thicknesses, thus obviatin the necessity of a se arate adjustment for t iis purpose.

. l rom the foreoing, it wil be readily appreciated that provide an exceeding y cheap, strong, durable, and simple device for oyed.

what I claim as new and desire to secure by Letters Patent is 1. A saw clamp comprising a stationary the entire clamp, said racket having arching members terminating in eyes, a second movable panel ada ted' to work beneathsaid arches, and aving a longitudinal groove, and an operating lever, said lever ein journaled in the eyes of the bracket, and aving a member in engagement with the groove of the second mentioned panel.

2. A device of the kind described com: prising astationary section which is constructed of a single strand of spring wire bent intermediateits ends to provide a straight section which terminates at each end' in arches, the ends of which are bent into eyes to form journal bearings, the extreme ends being bent to provide U-shape supporting members, and a panel connected to the straight section, and an operating lever section also constructed of a single piece of wire and bent to provide a longitudinal section, the ends of which terminate in crank arms, and shaft portions, said shaft portions being journaled in the bearings of the stationar section, and a panel connected to the longitudinal section.

3. A device of the kind described comprising a stationary section having yielding ournal bearings, a panel carried by the section,v and a clamping section or jaw journaled in the bearings of the stationary section, said clamping section or jaw being constructed of a single )iece of wire bent to form crank arms, shaft )ortions, and a handle section, the said s aft portions being held in the yielding bearings .of the stationary section, and a panel carried by the said section or jaw.

4. A device of the kind described comprising a stationary section, and a clamping section or jaw pivotally'connected to the stationary section, said stationary section being formed of a single strand of sprin wire which is bent at its ends to provide are 1 portions, the extreme ends of which are bent mto "journal bearings which provide supports for the olampmg section or jaw and iaving'each end bent to provide substantially inverted U-shape supporting members.
