Letters Patent No. 94,653, dated September 7, 1869; patented 'in England, Nocemller 5, 1868.

IMPRovED MACHINE FOR NAILING THE SOLES To THE UPPERS or' BooTS AND SHOES.

The Schedule referred to in these Letters Patent and making parte of the sam To all whom. it may concern Be it known that I, JOSEPH F. SARGENT, of Mel- *rose, in the county of Middlesex, and State of Massachusetts, have invented Improvements in Machines for Nailing the Soles to the Uppers of Boots and Shoesgand I do hereby declare that the following, taken in connection with the drawings which accompany and form partof this specification, is a. description of my invention, sufficient to enable those skilled in the art to practise it.

My present invention relates particularly to that class of machines for uniting 'the soles and uppers of boots and shoes, in which the fastening-devices consist of nails cut from continuous lengths or coils of wire, and in which the boots or shoes to be soled rest upon a slice-supporting horn. the top or" which forms an anvil, against which the end of the nail is upset or clinched, my improvements having particular reference to and consisting inthe peculiar mechanism or arrangement of mechanism for automatically gauging the length of each nail 4out from the wire, in accordance with the varying thickness of the sole of a boot or shoe from lfoe to heel; the invent-ion also having reference to the peculiar construct-ion and arrangement of the mechanism for cutting oft" the wire end to form each nail, the mechanisn'l for transferring the nail so cut ofil from the place where cut to position under the nail-driver, and the mechanism for feeding the shoe.

The drawings represent a machine and details of a machine embodying my improvements.

A shows a side elevation of the machine.

B, an elevation ofthe opposite side of the head, or upper part of the machine.

C, a. front view ofthe head. l

D, a front view of the shoe-feeding and adj mechanism.

E, a View of the wire-feeding ratcllet-mechanism.

l, a, sectional view, taken on the line :v x.

G, a sectional view, taken on the line y y.

H, a plan ofthe nail-carrier, or device which transfers the cut olf nail from the position where cut to position over the nail-driver tube.

I is an edge view, and

J, a plan of the wire-cutters.

The views D, E, F, G, H, l, and J are enlarged from the views A, B, and C, the former showing the parts in full size, and the latter the parts in qua-rter size of the working machine.

a denotes the post, or standard, upon which is mounted the head b, which carries the shoe-feeding, wire-cutting and transfen'ing, and nail-driving mechanisms, all the movements otl which are effected by a drivingshat't, c.

l At the front of the head is the swing-plate d, rocking on a pin, e, and carrying the reciprocating awlacent bar f and the reciprocating driver-bar g, li denoting the awl, and the nail-driver, the reciprocating movements of the awl-bar being eifeeted byfa crank-pin, It, (projecting from a wheel on the end of the shaft c, and working in a cam-groove on a plate iixed upon the back of the bar f,) and the upward movement of the nail-driver bar being effected by the action of said crank-pin on a project on, l, on the back of the bar g,

is effected by a spring,`m. j

The swing-plate also carries the feed-foot n., which is iixed to and moveswith the swing-plate, the movement of the plate being e'ected by a cam, o, in the wheel p, on the end ofshaft c, acting on a pin, q, projecting into the cam from the back of the swing-plate.

In connection with the feed-foot, a detainer, fr, operates, said detainer pnassiug the shoe` down away from the feed-foot, and holding it, while thefeed-foot-moves back after the operation of the awl. This detainer forms the front-end of an arm, s, extending from a. slide plate, t, .a projection from which extends into a slot in one arm of a. rocker-lever, u, pivoted to the head l), as seen at A, the lever being worked by a. cam, c, into the groove of which a pin projects from the upper end of the lever.

llhe shoe-feeding, awl-piercing, and nail-driving operations are as follows:

W hen the nail is driven, the shoe is held up against the feed and nail-tube foot n, the swing-plate being toward the detainer r, as seen at- C. The driver-bar being next release-d from the pin le, the spring throws down the nail-driver, and drives the nail int-o the'hole previously made by the awl.

The swing-plate then moves forward, causing the shoe to be fed by the feed and nail-tube foot. The awl bar then descends, but before it reaches the shoe, the det-einer -r also descends, and presses the shoe down below the feed-foot, and while held by the detainer, the awl completes its descent, and punctures. the hole for the next nail. The awl then asoends, and while the' shoe is still held by the detainer, the feed-foot swings back, bringing the nail-driver exactly over the hole ,pnnctured by the awl. The driver is then thrown down, and the detainer raised to let the shoe up against the nail-tube foot, -the descent of the `driver and the rise of the detainer being simultaneous, or so nearly so that the nail-tube foot will be in contact with the shoe, and the detainer-foot still retain its hold, when the nail is driven, the detainer rising, however, from the shoe as soon as the nail is driven, and ,leaving the. shoe in contact with the feed-foot, so that it may be again fed forward. The nail-forming wire passes from a suitable reel down through a. guide-tube made in a plate, j, or between said plate and another, the wire in passing while the downward or nail-driving blow of the driver,
