Description

T UNITED STATES PATENT @Trion,
GEORGE ALMON D PERKINS, OF ESSEX, MASS, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO HIMSELF AND GEORGE ARTHUR FULLER, OF SAME PLACE.
BOOT AND SHOE NAILING MACHINE;
EPEGIFICATION forming part of Letters Patent No. 289,443, dated December 4, 1883. Application filed May 1, 1883. (N model.)
To all whom it may concern:
Be it known that I, GEORGE ALMOND PER- KINS, of Essex, in the county of Essex, of the Commonwealth of Massachusetts,have invented a new and useful Improvementin Machinery for Nailing Shoes; and I do hereby declare the same to be described in the following specification, and represented in the accompanying drawings, of which t Figure l is a front elevation, and Fig, 2 a side view, of a shoe-nailing machine of wellknown construction provided with my invention, the nature of which is defined in the claims hereinafter presented. tion taken through the driving-pulley and shaft and the friction-clutch of the machine.
Prior to my invention the cam by which the driving-pulley of the machine is moved into 7 thereby exerting not only a power with his hands, but one with his foot, a constant repetition of which requires an expenditure of much labor on his part, necessarily attended with fatigue to him.
With my improvement the pedal is entirely dispensed with, and the machine is set in action by the force exerted by the attendant in holding the shoe up to the nipple, for when i he does so he bears the shoe against a lever, and moves the latter so as to cause the driving-pulley to be clutched to the drivingshaft, and, consequently, the machine to be set in operation to drive the nail. Thus it will be seen that all the labor and attention required to work the plate is saved to the operator by my invention, and, besides, the danger of accident to him by reason of slipping of the shoe, so as to cause his hand to be wounded or injured by the machine-a matter of not infrequent 0c Fig. 3 is a sec currence-is overcome. So, before my invention, there has been, in a machinefor driving fastenings, the combination of a spider and a driving-pulley witha foot or proj ection,and mechanism connectingitwiththespider,whereby, upon the upward movement of the said'foot, the machine was set in operation, allbeing as represented in the United States Patents Nos. 246,487, 251,755, and 254,421. All such, however, differ from my improvement, which, though for a like purpose, is simpler in its construction and mode of operation.
In the drawings, a shoe-nailing machine is shown at A, it being of a kind well known and in common use in shoe-factories in Massachusetts and elsewhere. It is employed to nail the grooved outer sole to the lasted upper and inner sole of a shoe, preparatory to the removal of the last from them, and the subsequent sewing of the soles and upper by a Mo- Kay sewing-machine. This machine feeds the nail-wire at proper intervals into a channel to receive the nail, separates the nail from the wire, and finally drives it through the nipple atthe lower end of the channel, and thence into the shoe held up to such nipple. The driving-shaft of the machine is shown at a, its driving-pulley at b, and friction-clutch at c, the cam for moving the pulleyinto engagement with the clutch being represented at d. On pulling downward the said cam it is moved against astationary cam or inclined surface, 6, whereby such cam d is moved so as to force the'driving-pulley up to the clutch, a spring, f, producing a counter movement of the pulley at the proper time.
In carrying out my invention, I apply to the cam-rod g a lever, B, fulcrumed to the frame of the machine, and arranged as represented. The rod extends through the shorter arm of the lever, and is screw-threaded to receive two nuts, h and i, one of which is above and the other below the lever. The lever is to move vertically, its fulcrum being at k. "When the longer arm of thelever is at its lower position, the shorter arm brings up against a stop or abutment, Z, fixed to the frame of the machine. The longer arm of the said lever extends nearly to the nail-discharging nipple m of the machine, and is there provided with a curved prong, n,which, projecting down from the lever in manner as shown, is to enter the stitching-groove of the shoe-sole. Furthermore, there is fixed to the machineframe, and to the shorter arm of the lever B, a spiral spring, 0, which is to raise the shorter arm, in order to depress the longer arm of the lever, and to force upward thecam d, to enable the spring f to act so as to move the driving-pulley away from or out of engagement with the friction-clutch. Then the pulley is disengaged from the clutch, such pulley will not revolve the shaft, but will revolve freely on it.
In using the machine with my improvement, the attendant, with his hands holding the shoe, brings it up to the lever B, so as to cause the prong thereof to enter the stitchinggroove of the sole, or to touch the sole near to where he may desire to have a nail driven into it. Having done this, he is to press the shoe upward, so asto cause the driving-pulley to be put in engagement with the frictionclutch, and as a consequence the machine to drive a nail through the nipple and into the shoe soles and upper. Thus it will be seen that the force necessary to keep the shoe up to the nipple is also utilized in putting the driving-pulley into engagement with the clutch.
lVith my improvement I not only dispense with a pedal and the attention and labor incident to its working, but the heavy tripod as generally used for supporting it and the machine.
I claim in the nailing-machine 1. The combination of the lever B, screwthreaded cam rod nuts h i, cams d and c, and spiral spring 0, arranged with and adapted to the nipple m, and frame, driving-shaft and pulley and clutch of the machine, substantially and to operate as set forth.
2. The combination of the stop or abutment GEORGE ALMOND PERKINS.
