JEAN BERTON, on NEW YORK, N. Y.
SAW FILING AND.SETTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 285,557, dated September 25, 1883.
Application filed May 12, 1883. (No model.)
To all whom it may concern:
Be it known that I, JEAN BERTON, of the city, county, and State of New York, have in-- vented a new and Improved Saw Filing and Setting Machine, of which the following is a full, clear, and exact description.
and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in, which similar letters of reference indicate cor-l 1 tudinal groove, G,
responding parts in all the figures.
Figure 1 is a longitudinal elevation of my? improved saw filing and setting machineu Fig. 3 is a; cross-sectional elevation of the same and of Fig. 2 is a plan view of the same.
the setting device. Fig. 4 is a cross-sectional elevation of the same, showing the file-holder in longitudinal section.
said screw-spindle passing centrally and 1ongitudinally across the frame, and on one end of the same a pinion, B, is mounted, which engages with a cog-wheel, B rigidly mounted on a short shaft, Z), on which a rocking fork, O, is pivoted, which is provided with a suitable handle, 0. Between the shanks of the fork G a friction clutch-wheel, O is rigidly.
provided with a binding-screw, D", and with a pintle, (1, against which the forked lever can strike. By rocking the forked lever O in one direction or the other the wheel 0 will be turned, and with it the cog-wheel B which in turn turns the pinion B and the screwspindle B, on which it is mounted, and thereby a nut, E, through which the screw-spindle B passes, will be moved longitudinally in the Fig. 5 is aplan view of the setter, showing the top plate removed.
In a frame, A, resting on suitable stand ards, A, a screw-spindle, B, is journaled, the
frame A, which nut E is held in a transverse frame or carriage, E, adapted to slide on the side bars of the frame A.
Two guide -tracks, F F, are secured to a plate, F, pivoted to the middle of the bottom of the transverse frame or carriage E, so that the said guide-tracks F F can swing on the central pivot. A file-holder carrier, G, is constructed of ablock havinglongitudinal grooves in the sides, into which grooves the ridges of the guide-tracks are adapted to pass, whereby thefile-holder carrierwill be guided while being reciprocated in cutting the teeth of the saw.
' In the bottom of the file-holder carrier a longiis provided, in which a file-holding block, H, is held to move vertically, the said block being provided at one end with a downwardly-projecting part, H, having an aperture, through which the handle end of the file can be passed, on the bottom of which projection H a curved hook or clutch, H is held by a binding-screw, h,which also holds the end of the file I in place. The free end of thefile rests in a short grooved projection, h, on the under side of'the block H. y
The file I is held at its handle end, and is pressed forward a short distance from the handle endby the end of the hook or clutch H, whereby the file I is held in place on the bottom of the block H. Screws K pass through the top of the file-holder carrier G into the block H, and are surrounded by springs K, which press the block H downward.
The carriage E is provided with a bindingscrew, E, for locking the central plate, F, to which the guide-tracks F are secured, in place on the frame E.
The saw is held between two longitudinal jaws, L and L, of which the former is secured to afixed support, 1, whereas the latter is secured to the upper end of a lever, M, pivoted in standards N, the lower end of the lever M passing in between the shanks of a fork formed at the upper pivoted end of a foot-lever, O, pivoted in the lower part of the standards N. The fixed jaw L is provided along its lower longitudinal edge with an upwardly-project- -L is provided with two or more apertures for receiving the pintles m of an inclined checkrail, Q, which is adapted to rest upon the up-' per edge of the said jaw L, as shown in Fig. 3, while the saw is being swaged or set.
Ihe saw-setter is composed of a block, R, provided at its front end with a downwardly-proecting hook, R, adapted to catch on the flange P, and at the other endwith a downwardly-projecting handle-piece, B". A downwardly-inclined sliding bolt, T, is held in the frontpart of the surface ofthe block R, whichboltTis drawn nward and upward by a spring, T, surrounding The upper inner end of the bolt T rests against atrigger, U, pivoted in the blockB and projecting downward from the same, whereby, by pulling the trigger U, the bolt T will be moved downward and outward. The block Bis usually so arranged that the hook B rests againstthe flange P, and the lower end of the 1 bolt, which is suitably beveled and pointed, can strike the teeth of the saw and bend them as may be required.
The operation is as follows: The lever O- is raised, whereby the jaws L L will be separated. The saw WV is then placed between the .jaws in such amanner that the teethvproject above the upper edges of the jaws, and the saw is then firmly clamped and held between the said jaws by pressing the lever O downward,'whereby the lower end of the lever M will be moved outward, and the movable jaw L will be pressed toward and against the fixed jaw L. The screw-spindle B is so adjusted that the transverse sliding carriage IE will be atone end of the frame A. The file I is fastened intheblook H of the file-holder in the manner described, and the screws K of the file-holderi areso adjusted that the springs K, surrounding same, press the block downward to such an extent that the file will cut the desired depth into the edge of the saw. The tracks F{ can turn freely on the bottom of the'transverse carriage E; or they can be locked in position at a desired inclination, so that the inclination: of the edges of all the teeth will be the same. I The file is then reciprocated by sliding the file 1 holder backward and forward between the: guide-tracks. After a tooth has been filed or cut, the lever C is thrown once, whereby the carriage E will be moved the desired distance, and then the next tooth is filed. That the? carriage may be moved the same distance every time that the lever is thrown, the sliding block D on the frame -D is so adjusted that when the lever C strikes against the'pin-H tle d of the said block the screw-spindle .B will have moved the carriage the desired dis-j tance. In this manner all the teeth of the saw are filed. If the teeth are to be set, the checkrail Q is placed on the movable jaw L, and. the hook B of the block R is placed against; the inner edge of the flange P, andthe bolt '1 is moved downward by means of the trigger U, in the manner described, whereby the teeth will be pressed laterally, the check-rail Q preventing-them from being pressed too-far. As the alternating teeth only are pressed in the same direction, the saw-blade mustbe removed and reset, so as to permit of the remaining teeth being bent in the inverse direction.
By'means of the above-described machine the saws can be filed and set very rapidly, can be placed in the clamp or removed from the same very quickly, and all the teeth are filed accurately and are all alike, as the file-holder is moved the same distance every time that its lever is thrown. The saw-setter handle B is held in the hand while operating with it; or the setter can be placed on a suitable support. Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with the frame A, the carriage E, reciprocating in said frame, and the screw B for reciprocating the same, of the plate F, pivoted to the carriage, and provided with theguide-tracks F, and the filo-holder carrier G, reciprocating in said guide-tracks,
substantially as herein shown and described.
2. In a saw-filing machine, the combination, with the carriage E and the screw B, provided with the pinion B, of the gear-wheel B, the forked lever O 0, provided with thepawl c, and the friction-wheel C, substantially as herein shown and described.
3. In a saw-filing machine, the combination,
with the carriage, operating-screw B, provided with the pinion B, the circular frame D, the gear-wheel B, the lever' G 0, provided with the pawl c, and the friction-wheel G", of the sliding block D, held adjustably'on the said circular frame and provided with the pintle d, substantially as herein shown and described.
4. Ina saw-filing machine, the combination, with the reciprocating file-holder carrier G,
provided with the longitudinal groove G, of
the file-holding block H, fitting in the groove of-the carrier, the screws K, and the springs K, surrounding said screws, substantially as herein shownand described.
5. In a saw-filing machine, the combination, with the file-holding block H, provided with the apertured projection H and the grooved projection h, of the clutch H and bindingscrew h, substantially as herein shown and described.
6. In a saw-filing machine, the combination, with the fixed jaw L, of the movable jaw L, the lever M, secured to said movable jaw, and the forked foot-lever O, substantially as herein shown and described.
7. The combination, with the frame and the clamping-jaws of a saw-filing machine, of the block B, the sliding bolt T, and the trigger U, substantially as herein shown and described.
8. The combination, with the frame and the clamping-jaws of a saw-filing machine, of the block B, provided with the handle R the sliding bolt T, the spring T, and the trigger U, substantially as herein shown and described.
