MACHINE FOR AUTOMATICALLY OPERATING SAW SWAGES AND SHAPERS.
Application filed September 25, 1911.
To all whom it may concern Be it known that I, Fnnnmor: REcnNoLn, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Machine for Automatically Operating Saw Swages and Shapers, of which the following is a specification.
The present invention has for its object, the provision of a novel mechanism for operating hand swages and hand shapers, which are in general use in fitting band saw teeth, thereby obviating the manual labor, which attends hand swages and hand shapers.
For a full description of the invention thereof and also to acquire a knowledge of the merits and construction of the machine, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side view of the machine. Fig. 2 is a plan view. Fig. 3 is an end view, at 3, showing end of the frame, also a part of the mechanism to be described further on. Figs. 4, 5 and 6 are the arms to which the swage is to be connected. Fig. 7 is a detail side elevation with parts broken out of shafts 6 and 7 and the parts carried thereby.
The frame or body of the machine, consists of the ends 2 and 3 and bottom 4 and top 1, and may be made of any suitable ma terial, preferably of cast iron.
The driving shaft 5 is supplied with driving pulley 10 and pinion 11, the pinion to mesh with gear wheel 12, which is secured to shaft 6. The shaft 6 is fitted with sprocket wheel 13, also eccentrics 14, and 16 and cam 17.
The arms 18, 19 and 20 are pivoted on stationary shaft 7. The lower portion of arms 19 and 20 are segmental in form and extend from pivoting shaft 7 downward and to the right of eccentric shaft 6. The lower portion of arm 18 is al o segmental in shape and extends from the pivoting point to the left of eccentric shaft 6. Slotted frames 21, 22 and 23, with rollers 24, 25 and 26 attached, are fitted to the circular portion of arms 18, 19 and 20, and are designed to control in part, the throw of the arms 18, 19 and 20. The extreme lower ends of arms 18, 19 and 20 are designed to receive the ends of the coil springs 27, 28 and 29, the opposite ends of the coil springs, belng attached to the brackets 30, 31 and 32 secured Specification of Letters Patent.
Patented Apr. 21, 1914.

to the bottom 4 of the frame. Brackets 30, 31 and 32 have a multiple of taped holes, as also have the lower ends of arms 18, 19 and 20 these holes allow the adjustment of the tension of the coil springs. Extensions 33 and 34 are on the upper part of the arms 18 and 20 and are of spring form, but can be made rigid, and are attached to the upper portion of the arms 18 and 20 by the thumb screws, as shown at 35.
36 is a piece of the band saw between the vise jaws 37 and 38. J aw 37 is secured to the ends of the frame 2 and 3 and jaw 38 is hinged to the ends 2 and 3.
Lever 39 is pivoted at 40 and connects with lever 41 which is pivoted at 42, lever 41 is provided at its extreme end with roller 43. Cam 17 is adjusted to the roller 43, so as to cause the vise jaw 38 to clamp the saw tightly against the jaw 37, while the saw tooth is being swaged and shaped, and is released when the saw is pushed forward.
44 is a slotted frame with a roller 45 attached to the top end, which acts as a back rest for the saw.
The stop block 63 is to regulate in part, the throw of arm 19, in order to accommodate the diii'erent spaced teeth of band saws.
Arms 46 and 47 which operate the shaper are duplicates of arms 19 and 20, and are pivoted on the stationary shaft 48, and are operated by eccentrics 49 and 50, on shaft 51, and by the coil springs 52 and 53.
Eccentric shaft 51 is driven by chain 54, which is operated by sprockets 13 and 55.
Swage 56, which can be of any make, is attached to the upper end of arm 19 by the connecting bar 58. The clamp screw lever 64 of the swage 56 is connected to the extension 33 of arm 20 by bar 59, and eccentric lever 65 of the swage is connected to extension 34 of arm 18 by bar 57.
The shaper 60, which can be of any make, is connected to the upper end of arm 46 by a bar or rod 61. The screw lever 66, of shaper 60 is attached to the upper part of arm 47 by bar 62.
To more fully explain the mechanism and merits of my invention, I will describe" in detail its working parts.
On starting the machine, the saw tooth is placed against the anvil of swage 56, then eccentric 15, causes the upper end of arm 19 to move forward, thus pushing the swage against the point of the saw tooth, forcing the saw forward. While the pressure of swage 56 is against the point of the tooth, the arm 20 is suddenly released by eccentric 16, thus allowing the coil spring 29, which is under tension, to pull arm 20 backward. (The arrow pointing to the forward part of the machine.) This causes the swage to be clamped tightly to the saw; as soon as the swage is made fast to the saw, eccentric 14L forces the upper end of arm 18 backward, which causes the device in the swage to spread the point of the saw tooth, when eccentric 1 1, releases arm 18 and the coil spring 27, pulls the upper end of arm 18 forward into position for the next operation. At the same time, eccentric 16 forces arm 20 forward into position. As soon as the arms 18 and 20 are in position, for the next operation, then eccentric 15 releases arm 19, when the tension of the coil spring 28 pulls the top end of arm 19 backward, thus causing the swage to be drawn backward and over the next saw tooth. The clamping of the saw, while it is being swaged and shaped, and being released when it is pushed forward, is accomplished by the levers 39 and 41, as previously described.
The mechanism, which operates the shaper 60, is driven by the chain 54: as described, and the same is adjusted to shape the saw tooth, at the same time the swage operates upon the saw tooth, eccentric 4L9 forces the arm 46 and the shaper backward and over the point of the saw tooth, and when it is released by eccentric 49, the coil spring 52, pulls the shaper forward and up against the point of the saw tooth. The point of the saw tooth stops the forward throw of the top end of arm 16, the throw of arm 46, being adjusted so as to take care of the uneven spaces from point to point of the saw teeth.
' lvhile the shaper is against the point of the saw tooth, eccentric 50 forces the upper end of arm 47 forward, thus causing the screw lever 66 on shaper 60 to operate the dies 1n the shaper, then the arm 47 is released by eccentric 50, while the coil spring 53, pulls arm 47 backward into position. The arms 18, 19 and 20 and 46 and 17 are so adjusted to the eccentrics let, 15 and 16 and 4:9 and 50, so as to cause the machine to swage and shape the saw tooth in one revolution of the eccentric shafts 6 and 51.
7% is a coupling to attach a shaft (not shown), in order to operate the ordinary device for feeding around the opposite part of the band saw.
67, 68 and 69 are the cuffs, which fit over the handles of the swage and shaper to be used, and are made fast to the same by the thumb screws 71, 72 and 73.
Having thus described the invention, what is claimed as new is:
1. The combination of a supporting frame, a shaft revolubly mounted in said frame, eccentrics carried bysaid shaft, a swage, a fixed shaft also mounted in said frame, arms pivotally mounted on said fixed shaft and having extensions projecting into the path of said eccentrics, levers connected with said swage, and bars connecting said levers and arms.
2. The combination of a supporting frame, a shaft revolubly mounted in said frame, eccentrics carried by said shaft, a swage, a fixed shaft also mounted in said frame, arms pivotally mounted on said fixed shaft and having segmental extensions, slotted frames adjustably mounted on said extensions and having rollers extending into the path of said eccentrics, and coiled springs adj ustably 80 connected with said extensions and with said frame.
In witness whereof I hereunto aflix my signature in the presence of two witnesses.
