SPECIFICATION forming' part of Letters Patent No. 571,742, dated November 24, 1896.

Application tiled January 3l, 1896. Serial No. 577,522. (No mode-IJ To @ZK whom it 1x2/ay concern:

Be it known that I, AARON THOMAS Binn- ERD, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented cert-ain neuT and useful Improveinen ts in Sash Clamps 5 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention has for its objects, among others, to provide a simple and cheap sawclanip that can be folded so as to occupy but a minimum space and which can be quickly and iirmly fastened in position upon a bench or other support and which is practically selffastening and is an improvement on a siinilar device 'patented to nie July 1G, 1895, No. 542,819, to which reference is made.

Uther obj ects and advantages of the invention will be obvious from an inspection of the description hereinafter more fully set forth.

In the dra-Wings, Figure l is a view in perspective, sh owing the saw-clamp in position for use. Fig. 2 is an elevation showing the saw-clamp folded or in the closed position.

Fig. 3 is a vert-ical section taken transversely on one .side of the operating-levers.

Like letters of reference indicatie like parts throughout the several views.

Referring non' to the details ol the drawings by letter, A designates the body portion of the clamp, which is cast hollow throughout its major portion to render it as light as possible and at the saine time afford the requisite strength to withstand all ordinary uses to which it may be subjected. The upper end of the rear part B of the body port-ion A is provided 4with a shoulder or stop G, and 'ini- Jnediately above the stop G the rear jaw D of the clamp is pivoted through its middle portion at E to the upright or part B of the body portion. The rear jaw D is provided on its rear face With a shoulder or stop E', which engages the shoulder or stop C when the san'- elainp is in position for use. The ends of the rear j aw D are bent backwardly at right angles to the main portion of said rear jaw D and are provided with spurs A', which are de arm of the hollow standard.

signed to be driven into the bench or other support upon which the saw-clainp is to be fastened when in use. The lower end of the rear part B of the body portion A is provided with a hole F for the passage of a screwr for securing` the saw-ela1np in place when it is desired to locate it permanently.

The front jaw G of the clamp is east with a groove extending,` throughout its length on its rear face, and this groove II is filled at each end for a short distance With rubber, Wood, cork, or the like, which forin sounddeadeners I, which lessen the sound when an operator or Workman is liling a saw held in the saw-clamp. The front jaw G is pivoted to the upper end of a slotted lever L, which is fulcrunied in the upper end of the shorter The front jaw G is provided with a shoulder G', Which abuts against a shoulder G2 on the upper portion of the slotted lever L when the jaw Gf is in a horizontal position. Near the lower end of the standard is fulcruined a lever M, which is provided on one side, preferably near its inid- .dle, with a stud N, which projects into the slot P of the lever L and moves up and down therein when said leve-r M is ope-rated to open and close the jaws of the saw-clamp. The slotted lever L is provided near its upper end with a spring' Q, which normally bears upon the seniieireular front face of the front jaw of the saW-cla1np and holds it in the horizontal position, that is, the position it occupies when in use, but at the saine time permits it to be turned into the folded position, preferable for storage or transportation. The left end of the front bar or jaiv is heavier than the other end of said bar or jaw, the extra Weight causing said jaw to be normally held parallel with the rear jaw when in position for use. The spring secured to the slotted leif'eisarin serves to hold the front jaw steady and parallel with the rear jaw when the saw clamp is in the Working position.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A sauf-clamp, comprising the body portion A., the rear portion B thereof provided with shoulder C, jaWD pivoted at E and provided IOO with shoulder E and securing-spurs, slotted lever L pivoted to the front arm of the body portion and provided with shoulder G2, jaw G pvoted to said lever and provided with shoulder G', lever M pivoted to the frame and in operative engagement with lever L and spring Q attached to said lever L and normally bearing upon jaw G to hold said j mv in horizontal position, substantially as shown and described.

In testimony whereof I hereunto affix my signature in presenee of two Witnesses.
