LYMAN R. BLAKE, OF BOSTON, MASSACHUSETTS.

IMPROVED SHOE PEGGING AND NAILING MACHINE.

Specification forming part of Letters Patent No. 86,054, dated January 19, 1869.

To all whom it may concern:

Be it known that I, LYMAN R. BLAKE, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Shoe Peggin g and Nailing Machines; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification is a description of my invention sufticient to enable those skilled in the art to practice it.

In machine nailing or pegging boots and shoes upon a shoe-supporting horn, some of the nails or pegs, if all are of the same length,

,. will protrude beyond the inner surface of the inner sole, and this invention relates to a provision, in nailing or pcggin g machines, for removing the ends of nails which thus protrude; and the invention consists in combining, with the shoe-supporting horn of a pegging or nailing machine, a cutter or cutting mechanism, by which inwardlyprotruding ends of pegs or nails can be trimmed off while the shoe is upon the horn, and while the solin g operation is progressing.

The drawings represent a nailing or pegging machine having a shoe-supportin g horn embodying my improvement. A shows a front view of the head, with a sectional elevation of the horn; B, a plan of the horn.

a denotes the peggingmachine standard, upon which is mounted the head, carrying at its front the swing-plate b, in which slide the awl-bar c and peg-driver bar d.

The construction and operation of the peg or nail feeding, cutting, and driving mechanism and the shoe-feeding mechanism being well known, these parts need not be particularly described, nor are they shown, excepting in so far as is necessary to represent the arrangement in connection therewith of the horn and its cutting mechanism.

The horn e is so mounted that its bed or anvil-top f may be rotated under the awl and peg-driver, the shoe-supporting top being at a liked distance below the peg-tube foot, equal to the average thickness of the soles to be fastened, or the horn being made with provision for vertical movement to brin g the shoe up into contact with the peg-tube foot.

In vertical line with the descending awl the top of the horn is made with an aperture to receive the awl, or to permit the entrance of the ends of such pegs or nails as may be longer than the sole is thick, from the outer surface of the outer sole to the inner surface of the inner sole.

The horn rotates, in order that all the edge to be pegged or nailed may be brought into position for the action of the pegdriver, the progression of such edge under the feed-foot being effected by lateral movement of the awl when in the sole, or by movement of a feedfoot connected to and moved by the swingplate b.

On one side of the awl and peg-receiving aperture, at the top ot' the horn, and making one wall' thereof, is a bed-knife or stationary cutter, g, and on the other side is a reciprocating cutter, 7L, which is connected to and worked by a bent lever, i, said lever being connected by a link, 7c, with ano ther bent lever, l, which may be connected to and worked by mechanism connected with the pegging or nailing mechanism, so that after every nail or peg is driven the cutter h shall be driven up against the same, and, in connection with the stationary cutter, shall sever the protruding end of the nail or peg.

In the drawing, the lever Z is shown as connected with a lever, m, having aknob or head, n, by driving down which the movable cutter is actuated to sever the nail or peg, as will be readily understood.

It will be obvious that by this means every peg or nail which projects through the sole can be trimmed off iiush with the inner surface of the sole while the machine is in operation. This is particularly important when metal nails are used, as their ends or points cannot be easily ra-sped off after the shoe is nailed.

It is impossible, in nailing or pegging boots and shoes, to use nails or pegs of uniform length without their protruding into the inside of the shoe, on account of thc varying thickness of the sole from the toe to the heel, especially in the shank.

In the nailing-machine patented March 31, 1868, No. 7 6,150, I obviate this protrusion oi' the nails by bringing every nail just to the inner surface of the insole, as it is inserted, by using nails of different lengths, or each of a length gaged to the thickness of the sole,

the nails being cut from wire, and the feed of the wire to the action of the cutters being determined and gaged (automatically) by the thickness of the sole.

In my present invention I arrive at the same result-that is to say, I ultimately-bring'each nail to a length correspondin g to thel thickness of the part of the sole at which it is driven by cutting oft its inner end after it is driven, thereby dispensing with the mechanism which gages thelength of the nailv Instead of using a stationary or bed cutter and a movable cutter, as above described7 both cutters may be made movable, and be so hung that when they open (to let the end oi' the nail into the horn) they shall swing down below the top of the horn, while when they close to cut oft the end of the ynail their cutting-edges protruding peg 0r nail end, substantially as described.

LYMAN R. BLAKE.
