To aZZ whom it may concern: I E is the nail-carrier.

Be it known that I, FREEBORN F. RAYMOND, e isthe nail-carrier slide, to which the nail- 2d, a citizen of the United States, residing at carrier is secured.

It is adjustable or head, last, and work in this position during removable from the table 6. the driving of the nails,and then immediately permits the quick downward movement or descent or fall of the pressure-head and work, this downward movement of the pressurehead being facilitated by the springs O. This downward movement is immediately followed by another quick upward movement without rest, upward movement, and downward movement, there being no appreciable rest between the last upward and downward movements. The machine then stops. It will be seen that the first downward, second upward,and downward movements take place during the movement of the cross-head from its lowest position to just beyond its highest position when at rest. Upon the first downward movement of the pressure-head and work the top-lift-spanking plate F, carrying the top lift, if it is desired to blind-nail the top lift, is moved rapidly into position from one side of the boot or shoe or work-support over it, the cam f being constructed to provide the plate with this movement and also to hold it there for an instant during the secondupward movement of the pressure-head and work until the pressure-head and work have fallen slightly or sufliciently' to permit the reverse movement of the top-lift-spanking plate and its return to its original position. The top lifts may be placed in the toplift holder by hand or fed thereto by a feedplate moved automatically or by hand. The nail-carrier E is immediately moved forward upon the starting of the machine and comes into position to deliver its nails to the holes of the templet before the drivers enter its holes, and upon the upward movement of the cross-head immediately after the ends of the drivers clear or leave its holes its operatingcam moves it backward to a position to be filled with nails. The nails preferably are fed to it by automatic nail distributing and feeding devices similar to those described in various of my patents. The cross-head A is moved downward upon the starting of the machine, the drivers entering the holes of the nail-carrier and templet,driving the nails into the work, and then upward to its highest po sition, and then slightly downward, when the machine comes to rest. By giving the crosshead A sufficient throw, and by mounting the pressure-cam 0 upon the crank-shaft, and by constructing it as described,and by giving the vertical shaft 6 one revolution for every reciprocation of the cross-head, I am enabled to employ cams which will permit the parts to be moved as above specified, and to obtain very easy cams, and to well apply the power from the driving-shaft, and to very much simplify the construction of the machine as compared with that shown and described in the application referred to.

It will be understood, of course, that in this machine the heel-blank or work is not pricked,

can be used for any kind of work to which gang-nailing is applicable.

It will thus be seen that the machine herein described embraces in a complete organization means so combined and operated that by one revolution of a shaft the heel-blank is compressed, the attaching-nails driven, the top lift fed and attached, and the parts separated to permit the removal of the finished boot or shoe from the machine. It will further be noticed that to accomplish this result it is necessary that the last or work-support, templet or pressure-plate, and drivers should be, when the machine is at rest, held separated from each other to permit the shoe to be placed upon the last and the heel to be placed between the shoe and the templet, and also to permit the nails, unless they have been previously placed in the heel-blank, to be fed to the templet.

Upon the starting of the machine its first action is to compress the-heel-blank between the last or work-support and templet or presssure-plate and to drive the attaching-nails. This is followed by the separation of the last or work-support with the work thereon and the templet or pressure-plate and the introduction of the top-lift holdingand spanking plate or top-lift-spanking plate between them, and this in turn is followed by another compressing action between the last or work-support and templet, and this again is followed by the separation of these two parts, so'that during the complete action of the machine, or, in other words, during the rotation of the actuating-shaft, one engagement of the templet with the drivers and two engagements or impacts between the last or work-support an d the templet have taken place. This organization is especially valuable in heel-nailing machines, because it simplifies the construction of such machines and increases their capacity.

Having thus fully described myinvention,

I claim and desire to secure by Letters Patent of the United States 1. In a heel-nailing machine, a reciprocating cross-head carrying heel-attaching devices, a templet or pressure-plate, a last or work-support, a cam on the crankshaft for giving the latter two impacts and periods of separation during one revolution of the shaft, and a top-lift plate and mechanism for moving it between the templet or pressure-head and the work when separated substantially as described.
