IMPROVEMENT IN MACHINES FOR MAKING FASTENINGS FOR THE SOLES 0F BOOTS AND SHOES.-

Specification forming part of Letters Patent No. 188,354, dated March 13, 1877; application filed February 3, 1871.

; To all whom "it may concern Be it known that I, LoUIs GODDU, of Winchester, in the county of Middlesex and State of Massachusetts, have invented a new and useful improvement, being a Machine for Making Fastenings for the Soles of Boots and Shoes in integral wire or rods of distinct nails orpegs, having heads and points, of which the following is a specification:

The article to be manufactured consists of a sole-fastening for boots and shoes and other purposes, formed in continuous lengths of integral wire or rods of distinct nails or pegs having heads and points, and adapted to be fed by the inserting machine, and severed into nails or pegs, such severance being made either before or after the nail has been inserted, the heads of the integral nails or pegs serving as the means for making and governing the feed, and determining the point at which each nail is separated from the contin uous wire.

The machine for producing this article forms the subject of my present invention.

I employ rolls of small diameter, having dies of suitable coincident indentations the counterpart of the nail to be made, and incased in solid bearings, which support them directly above and below where the pressure is applied to keep the surface of the rolls in contact. At right angles to these rolls the passage for the wire is made in andthrough the solid incasement or bed, so that the wire can be fed to, and carried from, the rolls as it is formed into nails or pegs. The coincident indentations of the rolls are corrugated to effect the feed of the Wire, and to form corrugations upon the side or sides of the shanks of the integral nails or pegs, if desired. The surfaces of the rolls meet and join in their incased solid bearings; and to obtain such an arrangement of the rolls, their incased bed is divided into two sections, secured together by strongscrew-bolts, by which they can be adjusted as may be required to adapt the rolls for their proper work.

Motion is imparted to one of the rolls, which. is connected by equal gear to the other roll, and the effect of the corrugations of the rolls is to draw the wire between them informing the nails, the gearsbeing arranged and adaptedto make and maintain the coincident indentations in the wire by maintaining the :00- incidence of the head-forming indentations in the rolls. The arrangement of shoulders formed by the equal gears and of an outside fixed cap prevent the rolls from having any longitudinal movement. Atrimmin'g-pla'te is arranged at the exit-opening of the wire-passage in the solid bed, for taking off any fine burr on the edges of the wirewhich might be left upon it in passing through the rolls.

Two or more sets of dies can be made on i the rolls for separate use, thus saving the expense of making new rolls when one set is worn too much for use, the operation being conducted with one set of dies at a time, so thata single set of rolls can be used to-increase the capacity of the machine, while their incased bed is adapted for the removal of such rolls as may be required.

The wire is fed from a coil into the machine, I

and coiled as it is delivered therefrom in continuous lengths of wire or rods of distinct headed nails or pegs. p

The effect of the small rolls .is to stretch the wire in the direction of its length, and not to make any part of the nail .of greater width than the diameter of the wire, and to accomplish this it is of absolute importance that the rolls should be supported ,so as to prevent any springing by the pressure against them in rolling the wire with its heads, for the least springing ,or yielding of the rolls would cause the metal to spread, and the nails to be of irregular shape and useless.

completely incase them'and form their bearings, having bored-out cavities or bearings, into which the rolls are exactly fitted, so as to expose a small portion of their circumference, and to allow them to meet when joined in their solid beds. These die-rolls are made of small diameter-say, about three-quarters of an inch, and their pressure must be great enough to reduce the thickness of the wire, and form the heads by stretching the wire, and not byflattening or making any part of the nail of greater width than the wire. It is the small size of the rolls that enables me to accomplish this result, and in the employthe rolls stated will give four nails. The

lengthof the nail or peg to be formed, however, will determine this matter. Each groove is divided into an equal number of tapering indentations with cross-cavities, so that when the rolls are properly geared these indentations will be coincident, and form the heads and points of the nails alike on both sides of the wire, the heads and points joinin g throughout the continuous length, and for this purpose the taper of the indentations must be so gaged that the heads and points of each nail shall be joined. with the required strength to allow the wire to be coiled, handled, and operated in the inserting-machine. The wirepassage e is formed equally in the solid beds in line with the dies, forming a straight groove extending from both-sides of the rolls through which the wire is fed and supported, being entered from one side of the solid bed, and passing out at the other, producing in effect an inclosed way for the wire into and from the dies.

The'surfaces of the indentations or dies have transverse corrugations, which serve to draw the wire uniformly through the rolls, and to corrugate the sides of the shank of each nail, leaving only a plain space for the clinching-point.

The construction of these dies may, of course, be adapted to the form of any style of nail or peg, as, for instance the head may be formed only on one side of the wire, as in Fig.

6, in which case the rolls would nothave coincident indentations. Each die-roll has its own solid bed or metal case, and these are joined just in line with the circumference of the JOllS with true surfaces, and secured together by strong screw-bolts O, which pass vertically at suitable points through screwthreaded openings in the upper, and into screw-threaded openings in the lower, solid bed, holding them together so as' to resist thepressure upon the rolls. Dowel-pins f are provided on one 'of these sections or beds, to enter corresponding holes in the other, to efi'ecta perfect matching of the dies.

The die-rolls-are fitted endwise into their bearings, and are geared togetherby equal gears g h, upon their ends, outside of the solid beds, by which their nail-forming indentations are kept coincident. The die-rolls are prevented from having any endwise movement by means of the gears being a little greater in diameters than their rolls, to form shoulders, which bear against the sides of the solid beds, and a cap, D, firmly secured to one of the beds, against which the outer ends of the gearswork, so that, when properly seated,

the rolls are held truewith their dies.

I prefer to make the lower roll the driving- I roll, and to this the power is applied by joining an extension, E, of said roll, to a'driving-' shaft suitably arranged and driven, the connection being made by fitting the roll-extension into a socket in the driving-shaft and keying the two together, or by any other suitable means.

I combine with the exit end of passage for the integral nail-wire a plate, F, having an opening coincident with such nail-passage, the object of which is to trim off any fine burr or edge which might be left upon the wire in passing through the rolls, and thus deliver the continuous length of integral nails finished and complete, the opening in such trimming-plate being just equal to the diameter of the heads formed upon the wire by the dies, so that the opposite edges of the wire will be trimmed, as stated, as it leaves the solid bed.

By this method of rolling, the wire is not flattened, but simply stretched, and the malleability of the metal is thereby preserved, so that the nail-wire requires no annealing, and the nails will readily clinch when driven.

I have shown the rolls with a single die, but

it is obvious that two or more sets of dies or diegrooves and wire-passages can be arranged upon such rolls and solid beds, between the fastening screw-bolts, so that when one set of the dies is worn another can be used, thus adapting the same roll and bed-bearings to increase the capacity of the machine, and save the expense of making new rolls until all the dies are worn too much for use, when the rolls can be removed and renewed, using the same bed-bearings, which, being of steel, and the bearings of the rolls equal throughout their length, will last a long time.

Suitable appliances are arranged to deliver the wire from a coil into the wire-passage and the dies, and to receive and coil the completed nail-formed wire as it leaves the trimming-plate.

The screw-bolts which secure the two bedsections together have long loosely fitting washers, upon which the screw -heads are clamped, to make the fastening more secure.

The drawings represent the machine in full size, and with the solid bearin gs for the rolls of rectangular form; but these hearings may be of any form and construction, so long as headed sole-fastenings in continuous lengths of wire or rods of distinct nails or pegs, of dierolls, embedded and incased in solid bearings, to give the required support, with a feed-passage for the wire made through said solid beds, across and in line with the meeting-surfaces of said rolls, for the entrance of the wire to and its passage from said embedded dierolls.
