MACHINERY FOR BREASTJNG TH E HEEL'S OF BOOTS AND' SHOES.

SPECIFICATION forming part of Letters latent No. 282,255, dated July 31, 1883.

To all whom it may concern:

Be it known that we, JOHN VVOVARD BALL and HENRY CLARK, citizens of the Uniteding the Heels of Boots and Shoes, of which the following is a specification, reference being had therein to the accompanying draw mgs.

The invention relates to power-machines for breasting the heels of boots and shoes, in which a cutter operated by a treadle or other power device descends to breast the heel as the shoe is held in a last upon a support beneath.

The objects of our improvements are, first, to breast the heel by a cutter carried by a single vertically-moving arm, in such manner as to avoid the objectionable features of the common falling knife in the double standard; second, to provide means whereby said arm may be operated by power to descend to its breasting action, and to rise automatically out of the way when such action is finished, into a position in readiness for the next descent; third, to provide such a construction as will cause said arm, in rising automatically, to have a lateral'movement as well, in order to carry the cutter'up and away from the work and work.

man; fourth, to provide means for giving to the cutter, in addition to its vertical adjustment, a second adjustment for altering its angle' of stroke, so that it may be made to breast the heel, either with a plane vertical cut, or with a cut flaring inward toward the sole, fifth, to render the last or shoe support adjustable in any desired relation to the cutter in breastingdifferent kinds and sizes of shoes; sixth, to provide a stop for limiting the descent of the cutter to prevent its cutting the sole; and, seventh, to render said stop vertically adjustable. the mechanism hereinafter described, and illus trated in the accompanying drawings, in which Figure 1 is an elevation of our improved heel-breasting machine, showing the breasting-cutter as at the limit of its descent. Fig. 2, a top view, showing the cutter-carrying arm as raised and turned laterally out of the way Fig. 3, a front view of so much of the cutter- We attain these objects by Application filed May 14, 1883. (No model.)

arm as shows the stop and the adjustable cutter and its parts. Fig. 4 is a vertical longitudinal section on the line 4cm of Fig. 3. Fig. 5 is a rear view of the cutter-carrying bar, with the cutter attached; Fig. 6, a detail of the tubular standard, showing the camslot therein,

,-within which the guide-stop pin of the cutterarm rides; Fig. 7, a vertical longitudinal section of the last-support, and Fig. 8 a section on the line y y of Fig. 7, like letters indicating like parts in the several figures.

Let A represent the base of the machine, which is fastened to a table and otherwise suitably situated, and B a tubular standard rising therefrom a sufficent distance to give a long bearingsupport to a cutter-carrying arm, 0, which is operated within said tubular standard by a treadle-connection, D, or by :anysuitable connection with a power-shaft, and which is connected to D by a swiveling yoke, E, to permit of a horizontal movement within its long tubular bearing-standard. This movement takes place as it is lifted automatically by the action of the spring F, joined to the base A and the treadle, and a pin, a, which projects from the cutterarm, andpreferably provided with an anti-friction roll, following, as it rises, a guide-cam slot, 6, in the wall of the tubular standard B, curving to one side asuitable distance to cause the arm, as it rises to a sufficient height, to force its goose-neck G, or cutter-carrying part above the shoe, to turn laterally, and thus bring its end G out of the way of work and workman, and there to rest in the horizontal end portion 1) of said slot until forced downby the action of the treadle for another cutting operation. The bottom portion, 1), of said slot also limits the descent of the cutter-carrying arm, so that the movement of the arm vertically and laterally-is guided and controlled by the action of the pin in the slot. We prefer to give the arm this movement and to provide a construe tion for the purpose; but we do not limit our claim to invention to the construction shown, nor confine ourselves to its use in the machine, as not only may other constructions answer to obtain the desired vertical and lateral move ment, but the lateral movement may be dis pensed with and the force of the spring F depended upon to hold the cutter-arm raised up above the work until power is applied for the next stroke. It is also obvious that the move- I 011 which the shoe is heeled. The set-screw r ment of the arm may be continuous when steam-power is used.

The cutter-carrying portion G of the cutter-arm is of goose-neck form, as shown, and the arm may be solid or hollow, and'should be of cylindrical form for that portion which moves within the tubular bearing-standard, except when the lateral movement of the arm is dispensed with, in which case the form in cross-section is immaterial, so that the cutterarm may have its movement up and down properly within a suitably-long hollow bearing-standard. To this portion G of the cutter-arm the usual chisel-cutter, H, is fastened by a bolt, I, which passes through a slot, 0, in said cutter, and is secured by a nut, d, whereby the cutter may be adjusted vertically, as and for a purpose well understood; but in order to adjust the cutter as to its cutting angle, we provide set-screws K K, adapted to bear upon the inner face of the cutter, and to be set so as to permit of its use in making either a straight vertical cut or one which shall cut the heel downward and forward toward the sole. In a projection, G, of the cutterarm there is an arm, L, which has a stop-foot, L, which may have a cushion, f, and which is secured and held to proper vertical adjustment with relation to the cutter H by a setscrew g, as shown in Fig. 4.

The support M for the lasted shoe is of the usual form, modified by a construction to adapt it for being moved lengthwise and laterally upon a pivot and secured to a proper adjustment with reference to the cutter. WVe effect the lengthwise adjustment by constructing the support with a dovetailed lapping bottom, m, adapted to slide upon a dovetailed bed, N, by means of thumb-screw bolt a, and for the lateral adjustment we pivot the bed N at 0, and secure it in the desiredposition by a set-screw, r, passing into base A, which is inserted in a slot in the bed, (not shown,) so that it may have a lateral movement on its pivot 0, as will be readily understood.

The operative handles the shoe as in other breasting-machines, but much more rapidly and conveniently, and the same operativewho attends to the heelingmachine may have this machine within reach and breast the heeled shoes without any change of last from that upis capable of holding the shoe-support M in any fixed position of lateral adjustment; thus avoiding the inconvenience of holding the support by hand during the cutting. Hitherto the shoe-support has never been held to a definite position, but has had to be adjusted for each shoe. Our improvements avoid, also, any necessity for relasting the shoe taken from the heeling-machine.

WVe claim- 1. In a machine for breasting the heels of boots and shoes, the combination, of a hollow bearing-standard, an arm adapted for vertical movement therein, and having a gooseneck cutter-carrying extension, means for limiting the ascent and descent of said arm, a power-connection, and a shoe-support, substantially as and for the purpose described.

2. In a machine for breasting the heels of boots and shoes, the combination of a cutter arm having laterally-projecting cutter-carrying extension, and a guide-pin with a tubular bearing for said cutter-arm havinga guide-cam slot, a power-connection, and a shoe-support, substantially as and for the purpose set forth.

3. In a machine for breasting the heels of boots and shoes, in combination, the long tubular bearing-standard B, having the cam-slot I) I) b, an arm, G, provided with a pin, a, and swivel-yoke E, and having a goose-neck, G, carrying a cutter, H, a power-connection, D, a lifting-spring, F, and a shoe-support, M, substantially as and for the purpose described.

4. In aheel-breasting machine, the cutter H, adapted for an adjustment with reference to its angle of cut in the heel by means of slot etherein, and set-screws K K, passing through the cutter-arm, substantially as described.

5. In a heel-breasting machine, the rising and falling cutter-arm O G, having its cutter adapted both for vertical adjustment and to have an adjustment with reference to its angle of cut, substantially as and for the purpose set forth.

In testimony whereof we have affixed our signatures in the presence of two witnesses. JOHN WOVARD BALL. HENRY CLARK.
