Specification of Letters Patent.

Patented June 1 1, 1907.

Application filed October 3, 1905. Serial No. 281,193.

To all whom it may concern:

Be it known that I, ALEXANDER R. WIL- SON, a citizen of the United States, residing at Spokane, county of Spokane, State of Washington, have invented new and useful Improvements in Saw-Swages; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of this invention is to provide a stronger swage, more convenient adjustments, clearer view of working parts, and more wearing surface of the die than hereto fore used in tools of this class.

The particular manner in which the swage is constructed, and the die and anvil are adjusted to the saws, are fully set forth in the following specifications and illustrated in the drawings which accompany it :Figure 1 being a side view of the swage upon the saw, showing an end view of the die within the lever, the lever stop bracket, and means of adjustment. Fig. 2 being a rear view showing the manner in which the swage is clamped to the saw during the operation; also the means for clamping the lever to the diesleeve. Fig. 3 is a detail view of anvil. Fig. 4 is a detail view of anvil-casing and clamping screw. Fig. 5, a sectional view of A. 13., Fig. 2, showing the manner in which the anvil is adjusted to the die, and swiveled to the teeth-of the saw, and the means of extending the front bracket. Fig. 6, being view of opposite side to Fig. 1, showing the slot through which the anvil easing screw swivels, indicator finger and latch for holding die casing in the head. Fig. 7 is a sectional view of C. D., Fig. 6, showing die in casing, indicator, Washer and nut for clamping anvil casing to position, and the opening in the head through which the anvil is removed from and placed within its casing. Fig. 8, an end view of die and sleeve.

The drawings herewith shown are full size of swage, except length of levers shown brokenofl'.

In Fig. 1 is shown a side view of lever stop (10), indicator finger (11), and screws (12) which pass through slots to enable the indicator to be set to any of the graduations on the head, thus allowing the lever more or less movement as required.

The lever (13) Fig. 2, is adjusted on the die sleeve (14) by unscrewing nut (15), which releases the said lever from the ratchet grip,

and can be moved to the desired position.

Through the head, (16) F 2, a slot is cut for the reception of the saw. The means for clamping head (16) to the saw (17) is a screw (18) which is held stationary by jam nut (19) and the clamping-screw (20) which passes through lever (21) and is clamped thereon by nut (22).

A detail view of anvil (23) is shown in Fig. 3; (24) being a handle for removing the anvil or placing it within the head.

Shown in Fig. i, is a detail of the anvil casing (25), and clamping screw (16).

Fig. 5 is a section view along the line, A. B. Fig. 2, showing an open space each side of the anvil casing (25), which is to allow the anvil and said casing to be swiveled upon the die sleeve, to fit the top edge of the saw teeth.

Anvil (23) is held within the casing (25) by means of screw (26), or removed therefrom by turning the screw until the flat edge is parallel with the said anvil. Screw (27) is for adjustment of the anvil (23) to the die (28), thus admitting the amount of saw teeth required between the anvil and die. Shown at 29 is a spring which has a twofold purpose. First, to keep the anvil taut against 27; secondly, to act as a guide in sliding the swage over the points of the teeth to the die.

Saw blade (17) is shown in a position to be operated upon, anvil (23) being held rigid and die (28) being rotated from right to left, reducing the space in which the point of the saw tooth is held, thereby spreading the metal at the points of the teeth.

Upon the anvil adjusting screw (27) is a graduated disk (30), provided with a groove (31), and pin (32) to cause the disk to revolve as the screw passes through it. The disk (30) is held to position on the head. by indicator finger (33), and retained to position required by tightening screw(34) upon clamp (35). j

The front bracket (36) is herein illustrated with an extension (37) which is adjustable to rest upon one or more teeth of the saw as desired; the shoe to rest upon the points of the teeth and spring (47) to allow the head to tilt forward upon the points of the saw teeth.

In the side view, Fig. 6, washer (38) forms an indicator finger showing the position of the anvil in relation to the die 5 the dotted lines showing the slot through which clamping screw swivels.

The anvil casing is held to position in the head by means of nut (39) tightening against washer (38) upon screw (46).

The latch (40) swiveling on screw (41)is shown entered in annular groove (42) to retain die sleeve (14) within the head.

Illustratedin Fig. 7 is a section view of C. D., Fig. 6, showing the die (28) within the sleeve (14) and the sleeve latched within the head in position for operating. At 43, the sleeve is shown cut away to enable the operator to see clearly the relative positions of the die and anvil and for convenient removal of the anvil from the head. As the die is held rigid within the sleeve, and the sleeve retained within the head by latch (40), the die and sleeve can be oscillated within the said head, by means of lever (13), until the elliptical surfaces of die (28) come in contact with the anvil.

A sectional view of the die is shown in Fig.

5, numeral 28, which illustrates a perfect ellipse, being parallel length-wise and reversible, to enable the operator to adjust the die on being worn to new positions. As the die (28) wears from abrasion against the saw teeth, by releasing set screw (44) the die can be moved to a new position in the said casing (14), and repeated until the die is completely worn out along the contacting edges.

The die (28) herein shown is elliptical in form; but although this form is in every way suitable for saw swaging it is obvious that other shapes of dies may be applied to the sleeve (14) without departing from the spirit of my invention.

These form the essential structural elements of the swage, and the further description relates to the operations in using this device.

The swage being placed upon the saw tooth as shown in Fig. 5, the lever (21, Fig. 2) is pressed forward to clamp the head rigid to the saw. Lever (13) is then pressed forward, compressing the point of the tooth between anvil (23) and die (28), thus spreading the metal at the points of the teeth. Lever (13) is then returned to its original position and lever (21) likewise, which completes the operation on each tooth.

I am aware that, prior to my invention, saw swages of the same general character have been used for spreading the teeth of saws; but believe I am original in the open space in the side of the head for tlfe reception of the anvil; the swiveling of the anvil casing upon the die sleeve; the insertion and adjustment of die in a sleeve; the "adjustment of front bracket the lever adjustment on the die sleeve; and the form of die herein shown.

Having described my invention, what I claim as new, and desire to be protected in by Letters Patent, is

1. In a saw swage, a head, a die member pivotally mounted therein, a casing having a pivotal bearing mounted upon the die member, means for securing said casing in position, and an anvil supported by said casing.

2. In a saw swage, a slotted head, a die member pivotally mounted therein, a casing having a pivotal bearing upon the die member, means for securing said casing in position, an anvil supported by said casing, and a rotatable retaining member mounted upon said casing to engage the outer face of said anvil.

3. In a saw swage, a head, a'die member mounted therein, an anvil, and means for mounting said anvil upon the die to swing in an arc concentric with the center of the die.

4. In a saw swage, a slotted head provided with a curved adjusting slot in one of its side walls, a saw swage die mounted in the lower portion of said head, an anvil casing pivotally supported upon said die and provided with a securin member extending there from through the curved slot of the head, and an anvil slidingly mounted upon said casing.

5. In a saw swage, a slotted head, an anvil slidingly mounted therein, and a flat guiding spring disposed beneath the upper wall of 9 said slot and contacting with the face of said anvil to support the same above the tooth of a saw.

6. In a saw swage, a head, an anvil casing provided with a channel therein, an anvil mounted for longitudinal movement in said channel, and a retaining screw mounted in the casing and projecting through a slot in said head to permit a lateral adjustment of the anvil and its casing.

7. In a saw swage, a head, an anvil mount ed therein, an adjusting screw mounted in said head and bearing on said anvil, and a graduating disk surrounding said screw and slidingly mounted therewith for relative rotation.

8. In a saw swage, a head, an anvil mounted therein, an adjusting screw mounted in said head and bearing on said anvil, a graduating disk surrounding said screw and slidingly connected therewith for relative rotation, and a clamping device disposed upon said head to engage said disk to retain the same against longitudinal movement with the screw.
