SPECIFICATION forming part of Letters Patent No. 518,023, dated April 10, 1894.
Application filed July 26, 1893. Serial No. 481,488. (No model.)
. To all whom it may concern.-
Be it known that I, WILLIAM P. DAVIS, a citizen of the United States, residing at Rochester, in the county of Monroe, in the State of New York, have invented certain Improvements in Key-Seating Machines, of which the.
and illustrated in the following specification and the accompanying drawings,the novel features thereof being specified in the claims annexed to the said specification.
In the accompanying drawings represent:
ing a key-seating machine embodying my imcollars and spring on the clamping rods.
provements,-Figure 1 is a front elevation. Fig. 2 is a plan View. Fig. 3 represents the pressure or clamping bar as seen from the rear side. Fig. 4 is a central vertical section of the Fig. 5 is a plan view of the central portion of the clamping bar. Fig. 6 represents the sliding back and other support detached. Fig. 7 is a section on the line 7-7, Figs. 5 and 6. Fig. 8 is a vertical section representing the operation of the cutter-support. Fig. 9 represents a modified manner of attaching the clamping bar on an enlarged scale, the table not being shown. Fig. 10 is a plan view of the same. Figs. 11 and 12 represent the eccentric and handle for clamping the bar. Fig. 13 is a plan of a sectional detail.
A, Fig. 1, represents a suitable supporting frame, which is made in the form of a pillar, provided with the door G, and inclosing the gearing H I, by which motion is transmitted to the reciprocating toothed bar or cutter D.
B is the table, supported on the pillar A, and provided with the threaded stud bolts F F, and the pressure or clamping bar 0.
E represents a gear clamped in place on the table by the bar 0, in position to have a key-seat cut in the opening in its hub by the cutter D.
Power is applied to the machine by means of suitable pulleys on the shaft of the gear H, which meshes with the gear I, carrying the crank pin band communicating motion by the pitman a to the cross-head 0. Suitable guides d'd are arranged inside the pillar, in which the cross-head reciprocates. The cutter D isattached to the cross-head by the bolt or'screw e. The cutter passes through suitable guides in the table. The stud-bolts F F are screwed or otherwise inserted in the tabla-provision being made for placing them at-different distances apart, to adapt the machine for handling large or small gears.
N N represent adjustable gages which may be provided with adjusting screws, and attached to the table by bolts inserted in some of the series of holes 1) in the table, by which means the gears of diiferent sizes may be set in suitable relations with the cutter. The gages serve to locate the gears inthe proper positions on the table. The clamping bar 0 is-made with the flanges f and g,the horizontal flange 9 being provided with a series of notches m and a, through which the studs F F pass. The stud-boltsF F are provided with a series of collars, h, through which the pressure of the nuts Z is transmitted to the clamping-bar O, which is thus caused to hold the gear firmly against the table. Below the bar, the stud-bolts F F are provided with the washers t 'i, having recesses j on their opposing faces, and inclosing the springs k, which serve to raise the bar O.when the nuts lare loosened, and thus facilitate the insertion and removal of the gears. The springs serve to adapt the bar to any thickness of work. The flange g is notched or recessed where the cut ter passes through it. The bar 0 supports a sliding block 10, which carries the pivoted cutter-support 0, which bears against the back of the cutter during the downward stroke, and swings upward during the up stroke, so as to relieve the cutter, as indicated by the full and dotted lines in Fig. 8. The sliding block and cutter-support are arranged to be adjusted lengthwise of the bar by means of the screwrod K, provided with the hand-wheel J, and passing through the threaded boss to. The innor end of the rod is fitted to a lug, to, Figs. 6 and 7, attached to one side of the sliding block, and arranged to move in a suitable recess y, Fig.3. The shaft is reduced in size where it passes through the log, and has a nut z, Fig. 6, on its end. The sliding block p is secured in place on the bar against the flanges f and g, by the angular plate L, which is fastened in place by the screws u, Fig. 7, having countersunk heads and passing upward frombelow the bar g, and the screws, 01., passing horizontally through the flange f. The cutter-support 0 is pivoted at rin a slot or recess in the upper part of the block 19. A recess, 0, Fig. 8, is formed in the lower side of that portion of the angular plate L which passes over the sliding block, to permit the movement of the support 0. A leaf spring, 1, is secured to the upper side of the sliding block 19 by the screw .9, and bears on the top of the support 0. b, Fig. 5, is a plate adj ustably secured to the bar and carrying a scale (5'. A pointer, cl, attached to the block :10, passes over the scale as the sliding block is adjusted by the screw rod K. An adjustable stop is arranged to limit the movement of the sliding block, to determine the depth of the key-seat. The screw g Figs. 2, 5, and 6 serves conveniently for such stop. This screw is inserted in the bar 0 in a threaded hole, being arranged so that its point comes opposite the end of the threaded adjusting rod K, and it arrests the inward travel of the rod and the sliding block at any desired point. In Figs. 9 and 10 the clamping bar 0 is supported by the shaft T and the rod P, carrying the eccentric Q, by which the bar is forced against the gear E. In this arrangement of the bar, it may be attached directly to the table B, but is preferably carried by the plate W, which is provided with openings 71. for bolts by which it is secured in place on the table. The plate lV has a slot 'i' in which the cutter D plays. It is also provided with an adjusting screw V, which passes through alug on the plate, and also through a threaded block 12 secured to the table. (Not shown.) The shaft T, passes through a boss Z, which is split on one side. The split is extended through the connected part or projection of the table as indicated in Figs. 9 and 13 and is provided with screw U, by which the shaft is clamped in the boss in any position in which it may be set, to adapt the machine to difierent thicknesses of gears or pulleys. The bar 0 is pivoted on the bolt on in the yoke 'n'n' on the upper end of the rod T. The bar is channeled on its upper side to receive the threaded rod K, to the inner end of which the sliding block 19 is attached in any suitable way, so that it is drawn backward and forward by turning the rod. The block slides in a recess in the bar, being held in place by the plate or cap L. The block carries the pivoted cutter-support 0, which is pressed down by the spring (1. The inner end of the bar is provided with the extension or bearing piece X, which is slotted to receive and guide the cutter D. The threaded rod K passes through a threaded boss g on the end of the bar 0. The rod P is inserted in the table, in suitable relation with the bar 0, so that the eccentric Q maybear on the upper surface of the bar, and force the piece X against the gear. The eccentric Q is carried by the spindle S, provided with the handle R and arranged to revolve in the block Y, which slides up and down on the rod P, being provided with the clampingscrew 4*. By turning the handle R from the position indicated by the dotted to the full lines in Fig. 10, the eccentric is caused to clamp the bar and gear in place. The screw V serves to adjust the plate \V on the table of the machine, so that any desired taper or bevel may be given the key-seat.
I claim 1. The combination, in a key-seating machine, of the supporting table, the reciprocating cutter, the clamping bar 0, having flange f, the sliding block 19 carrying cuttersupport 0 and spring q, the angular plate L and the adjusting screw K, substantially as described.
2. The combination, in a key-seating machine, of the supporting table, the reciprocating cutter, the clamping bar, and pivoted cutter support, of the threaded rods F F, recessed washers i andspring 7c, substantially as described.
3. The combination, in a key-seating machine, of the supporting table, the clamping bar, the recessed sliding block 19, pivoted cutter-support o, and spring q, attached to the sliding block and bearing on the support, and the adjusting screw K, substantially as described.
4. The combination, in a key-seating machine, of a suitable support,the reciprocating cutter, clamping bar 0 carrying pivoted cutter support 0 and spring q, the shaft T supporting the outer end of the clamping-bar, the rod P, adjustable block Y and the cocentric Q, and the adjusting screw K, substantially as described.
