THOMAS M. KENNA, OF NEW HAVEN, CONNECTICUT, ASSIGNOR OF ONE- HALF TO JEREMIAH J. SULLIVAN, OF SAME PLACE.
SAW-FILING MACHINE.
SPECIFICATION forming part of Letters Patent No. 612,423, dated October 18, 1898.
Application filed m 16, 1897.
To all whom it may concern.-
Be it known that I, THOMAS M. KENNA, of the city and county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Saw-Filing Machines, of which the following is a description, taken in connection with the drawings, which form a part thereof, and in Wl1lCll- Figure 1 is a side elevation of a saw-file embodying my invention; Fig. 2, a longitudinal vertical section through the same; Fig.3, a detail side view of the arbor; Fig. A, similar views of the divided collar for the file; Fig. 5, a side elevation of the file proper, and Fig. 6 atransverse section of the clamp for the saw.
This invention relates to files for filing saws, and has for its object the construction of a machine for filing saws in which the file is mounted on a revolving arbor and is of helical form, so that the operation may be continued from one tooth of asaw to the succeeding tooth without the interruption of the movement of the machine.
In the drawings, A represents the main frame of the machine, which is adapted to be bolted or otherwise secured to a suitable bedplate or foundation. Standards B and B are formed integral with the frame A and have at their upper ends divided journal-bearings b. and b for a rotary spindle D.
A cap C, having secured on its under side a flat tension-spring c, is adapted to fit over and be secured to the tops of the standards B and B to secure the hearings in place and so that the free end of said spring 0 will bear against the top of the forward bearing 19. A set-screw c is adapted to pass through the cap C and bear against the spring a, the ten sion of which is regulated thereby.
The spindle D has rigidly mounted near its rear end a band-pulley E, to be operated on by a belt, (not shown,) and near its forward end, outside of the standard B, is rigidly mounted an arbor F, having an annular flange 5 f, formed integral therewith at its forward end, and a peripherical shoulder f as shown in Figs. 2 and 3. The annular fiangefis adapted to receive a dividedcollar G, formed of two sections g and g, each having an abutment g and 9 adapted to engage with each other and unite the two parts of the collar G.
Serial No. 644,833. (No model.)
The collar G when the two parts are so united has 011 its periphery a helical-shaped groove 9 for the reception of a helical file H, beveled in cross-section. (See Fig. 2.) A plate I is adapted to be mounted on the forward end of said spindle D and bear against the outer edge of said collar G and hold the same against the shoulder f, when it is locked in position by a nut 2', screwed on the forward end of said spindle, which is screw-threaded for that purpose. In front of the forward standard 13 and formed integral with the frame A is a clamp K for holding the saw to be operated upon, consisting of a block is, having an inclined way and a plate L, inclined on its under side to correspond with the way 70, so that the upper edge of the plate L when in position is always horizontal. Plate L and block 7c are secured together by a set-screw Z, attached to the block 70 and passing through a horizontal slot Z in said plate L, thereby allowing the plate L a limited horizontal move men t. A flange Z is formed on the inner side of said plate L, parallel to the upper edge thereof, on which the saw is adapted to rest.
In operation the saw 0 to be filed is placed in the clamp K, and the plate L moved end- Wise on the inclined way It to raise or lower the position of the saw to adjust the depth which the operator desires the teeth of the saw to be cut, and the plate L secured to the block K by means of the set-screw Z. By means of this adjustment in the clamp holding the saw saws of various widths and teeth of various depths may be operated upon by the file. The sawis free to move in the clamp for the purpose shown hereinafter. The file H is mounted, as shown above, and is brought into position to operate upon the first tooth of the saw. cal-shaped file H on the rotating arbor F the saw is forced endwise in the" clamp by the engagement of the file with the tooth, and when a revolution is completed the endof the file will be in position to operate upon the next succeeding tooth upon the further revolution of the arbor. By means of the spring a, bearing on the upper portion of the forward journal-bearing b, the arbor F is allowed a slight play in a direction transverse to its length, so that as the file His rotated Upon the revolution of the heli to operate upon the tooth of the saw the spring 0 constantly tends to press it downward into deeper engagement therewith as it files away the edge of the tooth.
I-Iavin g now described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a saw-file, the combination with a rotary spindle; of an arbor rigidly mounted on said spindle, having an annular flange at its forward end; a divided collar formed of two sections, adapted to be mounted on said flange; a helical-shaped groove formed on the periphery of said collar; a helical-shaped file adapted to be mounted in said groove; and means for rotating said spindle, substantially as described.
2. In a saw-file, the combination with a standard; of a divided bearingin said standard; a rotary spindle journaled in said bearing; a file mounted thereon; means for rotating said spindle; a clamp for holding a saw in position to be operated upon by said file; a cap-plate over said bearing, and a spring between said cap-plate and upper portion of said bearing adapted to hold said file in contact with the tooth of said saw as it is operated upon, substantially as described.
8. In a saw-file, the combination with a helical file; means for rotating said file; a clamp consisting of a block having an inclined way, and a plate adj ustably mounted thereon, for carrying a saw to be operated upon by said file, substantially as described.
4. In a saw-file, the combination with a frame; of forward and rear standards, mounted on said frame; divided hearings in said standards; a rotary spindle journaled in said bearings, having at its forward end a flanged arbor, and near its rear end a rigidly-mounted belt-pulley; a divided collar formed of two sections adapted to be mounted on said arbor; a helical groove formed on the periphery of said collar; a helical file mounted in said groove; means for rotating said pulley and spindle; a clamp consisting of a block having an inclined way, and a plate adjustably mounted thereon, mounted on said frame, for holding a saw in position to be operated upon by said file; a cap-plate over said. forward bearing; and a flat spring between said capplate and upper portion of said bearing adapted to hold said file in contact with the tooth of said saw as it is operated upon, substantially as described.
In witness whereof I have hereunto set my hand, at New Haven, in the county of New Haven and State of Connecticut, this th day of July, 1897.
THOMAS M. KENNA.
