UNITED STATES EDWARD N. LARGE, OF TILLAMOOK, OREGON.

SAW CLAMP.

Application filed Jully 24, 1923. Serial No. 653,538.

To all whom it may concern:

Be it known that I, EDWARD N. LARGE, a citizen of the United States, residing at Tillamook, in the county of Tillamook and State of Oregon, have invented certain new and useful Improvements in Saw Clamps, of which the following is a specification.

This invention relates to saw clamps, and this particular clamp is designed primarily for large saws such as cross cut saws but of course may be used for the smaller variety, and in fact may be used for clamping other articles.

The primary object of this invention is to provide, in a manner as hereinafter set forth, a saw clamp which will clamp a cross cut saw firmly through out its entire length, and which may be raised, lowered, or set at an angle to suit the convenience. of the operator.

Another object is the provision of a clamp which will be etficient, strong, rable and inexpensive to manufacture.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming a part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings 1,

Figure 1 is a perspecti. view of the device embodying the invention.

Fig. 2 is a detail view ,-.f partly in section, of one end of the clamp, i-{Jand Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1 1.

Referring now to the drawings in detail, wherein like numeralsof reference indicate corresponding parts throughout the several views of the drawing, the device comprises a pair of channeled standards 11, having the channels turned away from each other as shown, each having the broad side split inwardly a short distance from one end as at 2, and each of the portions thus formed bent outwardly at right angles and flattened to form the supporting feet 3. Each of these feet ma be apertured to allow for the passage 0 bolts 4, should it be desired to secure the device to a base.

saw du- Each of the standards, at its other end, has through its broad side, a closed slot 5.

Slidable in the channels of the standards are other smaller short channeled members 6, each having its broad side bearing against that of the standard, and being provided with a plurality of apertures 7, to register with the slot 5, and having a bolt 8 and nut 9, adapted to pass therethrough for securing the channel members in various positions in the channel of the standard. .Secured in the upper end of each member 6, is a block 1.0, which closes the end of the channel, and through this block and the broad side of the channel an aperture is made for the passage of a threaded bolt 11, the threaded ends extending through'to the outside of the block and carrying thereon a crank 12.

Suspended between the channel members 6, are a pair of angled members 13 and 14 positioned back to back and forming the clamping jaws of the device, the member 13 has each end formed to provide a back turned ear 15, having an aperture therethrough for the passage of the bolt 11, by which the member is supported.

Positioned between the members 13 and 14 is a spacer 16, and is secured to one of the members by a rivet 17.

The members 13 and 14 are held together by a plurality of threaded bolts 18, which pass therethrough midway the upper and lower edges, and above the member 16. These bolts have one end secured in a plate 19, and the threaded end carries a tightening crank 20, interposed between which crank and clamping aw is a bowed spring washer 21.

Brace members 22, with securing bolts 23, may be provided between the standards and the base supporting the clamp, for strengthing the structure.

In using the device the members 20 are loosened to allow the jaws 13 and 14 to open, the saw is positioned therebetween, the back resting upon the bolts 18. The tightening arms are then screwed up, and because of the spacer between the lower edges of the jaws, the upper edges are drawn in tightly against the saw, holding it firmly in position.

Should it be desired to position the saw at an angle, the members 12, may be loosened sufficiently to allow the jaw 13 to be revolved to the proper angle when the cranks 12, may again be tightened. Either or o h ends of the saw maybe ai d or.
