SAW-SETTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 349,989,:1ated September 28, 1886.

Application filed January 230, 18 86. Serial No. 190,348. ("No model.)

To all whom, it may concern.-

Be it known that I, ORRIN G. FRANKS, a citizen of the United States, residing at Oneida, in the county 01' Madison and State of New York, have invented certain new and useful Improvements in Saw-Sets; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to saw-sets, the object being to provide a device of this character whereby the teeth of both straight and circular saws may be readily and quickly set.

The invention consists in the details of construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a perspective view of a saw-set embodying my invention, and showing the saw in position to be operated upon. Fig. 2 is a plan view. Fig. 3 is a sec tion on the line a; a; of Fig. 1. Fig. l is ascetion on the line y. Fig. 5 is a detail view of the anvil, and Fig. 6 is a detail view of the support for circular saws.

Corresponding parts in all the figures are denoted by the same letters of reference.

Referring to the drawings. A represents the anvil, which is provided with a projecting extension, B, formed integral with which is a head, I). In the head I) is formed an opening,

a, communicating with which is a threaded opening, 0, in which works a set-screw, d.

0 represents a curved or bent spring-rod, which is approximately U shape in form, and secured to the inner end of this spring-rod is a hammer, D, which is located directly over a ridge, 0, upon the anvil. It will thus be seen that when the saw is placed upon the anvil and one of the teeth struck it will be turned or bent to the desired degree. The hammer may be adjusted to or from the anvilbyloosening the set-screw working in the head of the extension and moving the spring-rod and then tightening the screw.

Erepresents brackets projecting from the anvil, which brackets are provided with openings, in which openings is located and adapted to slide a rod, f.

G represents curved arms, which have openings to receive the rod f, and adapted to clamp I said arms upon the rod are set-screws g, which work in openings and bear with their ends against the rod. The other ends of the arms a saw, as shown in Fig. 4., which is clamped in place by set-screws g.

The curved arms and rod sliding in the brackets of the anvil constitute the saw holding or supporting carriage before referred to. As the saw-holding carriage is pivotally supported,itwill be seen that when a tooth is struck the saw and carriage are liable to be raised from the anvil by the force of the blow. To prevent the raising of the carriage and saw, I have provided mechanism which I will now proceed to describe. Pivoted upon ascgmental plate, H, which is preferably formed integral with the anvil, is an arm, I,which is provided with an elongated slot, h, through which arm passes a bolt, i, which also passes through an are or segmental shaped slot, j, formed in the segmental plate H, said connection serving as a guide and support for the arm. Upon the free end of the arm I is pivotally mounted an arm, J, provided with a post, J, having a slot, 7., adapted to receive the saw, and communicating with said slot is a threaded opening, in which works a set-screw for clamping the saw in the slot. It will be seen that by securing this arm to the saw all upward movement of the latter and its supporti rig-carriage is pre vented. XVhen circular saws are to be set, the supportingcarriage before described may be removed and the arm clamped at the desired point and held rigidly in position.

K represents the circular-saw support, which consists of a post, K, having a conical cup or flange, K at its lower end, upon the upper end of which flange or cup the saw is adapted to be supported, the post passing through the opening in the saw. A sleeve, L, having an inverted conical flange at its lower end, fits upon the post, and is clamped in place upon said post byaset-screw, 7;. The conical sleeve fits in the opening in the saw, which opening islargert-hanthesupporting-post. Itwillthus be seen that said conical sleeve will firmly clamp the saw in place. The saw-support is held in place ad j ustabl y upon the slotted arm by a screw, m, which passes through the slot and has its head bearing against the sides of are provided with slots to receive the ends of 5 the slot, said screw entering a threaded opening in the lower end of the post K.

It will be understood that in setting a saw each alternate tooth is struck with the ham- 5 mer, and then the position of the saw reversed and the other teeth. operated upon.

Having thus described my invention, 1 claimy 1. In a saw-set, the combination,with an anvil having upwardly-extending brackets, of a rod sliding in said brackets, curved arms secured to said rod and adapted to receive and retain the saw, and a spring carrying a hammer, substantially as set forth. 1 2. In a saw-set, the combinationgvith an anvil, of a sliding carriage, means, substantially as described, for holding the saw, a pivoted arm, I, having an arm, J, pivoted to its outer end, said arm J carrying a slotted post, and a set-screw working in the post, substantially as set forth.

3. The combination, with an anvil having brackets, of a rod sliding in said brackets,

curved arms removably secured to the rod, and a spring carrying a hammer and adjustable to or from the anvil, substantially as set forth.

4.. The combination, with an anvil and a hammer, ofa sliding carriage, an arm pivotally connected with a segmental plate formed with the anvil and having a curved slot, abolt connecting the arm with the slotted plate, and a rod pivoted to the outer end of the arm and adapted to be connected with the saw, sub stantially as set forth.

5. The combination,with an anvil and ham- '3 5 mer, of a sliding carriage for holding the saw, an arm pivotally connected with aplate formed with the anvil, and a rod adapted to be secured to the saw and pivotally connected with the outer end of the arm, substantially as set forth. 40

In testimony whereof I affix my signature in presence of two witnesses.

ORRIN G. FRANKS.
