SPECIFICATION forming part of Letters Patent No. 243,601, dated June 28, 1881.
To all whom it may concern:
Be it known that I, ARTHUR NEWTON, of Boston, in the county of Suiolk'and State of Massachusetts, have in vented certain Improvements in Boot and Shoe Sole Nailing Machines, of which the following is a specifica tion.
This invention relates to machines for cutting corrugated r other wire into nails for attaching soles to boots and shoes, and driving said nails as fast as they are formed.
.The invention has for its object, irst, to provide an improved means for converting such Wire into nails, whereby the cutters used in forming the chisel-points on the nails are prevented from bending or distorting said points.
The invention also has for its object to pro-f vide certain improvements in a machine embodying mechanism for carrying' out my irnproved method of pointing, said improvements relating to mechanism for feeding the wire, mechanism for presenting the completed nails to the driver, and mechanism for feeding the boot or shoe sole while it is being nailed.
To these ends my invention consists in the improvements hereinafter described and claimed. v

Fig. 2 represents an end elevation of the same. vertical section on line yy, Fig. 2. vFig.4rep resents a transverse vertical section on line m Fig. 1.

Fig. 3 represents a longitudinal Application filed January 19, 1881. (No model.)
The same letters of reference indicate the same parts in all the gures.
In the drawings, A represents a frame of suitable construction for supporting the mechanism hereinafter described.
B represents the driving-shaft journaled in the frame, and provided with cams C, D, E, and F, for operating the Wire-feeding mechanism, the nail-pointing mechanism, the nail severing and presenting mechanism, and the driver-bar.
The nail forming or pointing mechanism is composed of a fixed block, H, rigidly attached to xed supports I I-on the frame A, and provided with a wire-guide orifice, K, a movable block, L, adapted to slide between the supports I I, and provided with a guide-orifice, M, adapted to coincide with the orifice K, and a pair of cutters or chisels, N N, rigidly connected and adapted to reciprocate in guides Nl N formed in the under side of the block H. The cutters N N are sepaited 'by a wedgeshaped space, O, and their inner sides form The ends of the cutters are beveled to form cutting-edges c e on the bottom surfacesand cutting-edges e2 e2 on the proximate sides of the cutters, as shown in Fig. 15. The bottom surfaces ofthe cutters are in close contact with the surface of the block L. The form and arrangement ot the cutters are such that when they are reciprocated they will have a planing action on and thus removek portions of the metal from the opposite sides of a wire, P, inserted in the guide-orifices K M, and thereby form notches a a, each notch being composed of a beveled surface, 1, subsequently forming one of the sides of achisel-point, and a surface, 2, substantially at right angles with the length of the wire, and subsequently forming a portion ofthe head or outer end of a nail. -The notches do not quite sever the wire, but leave a thin neck between the notches, which neck can be easily broken, as hereinafter described. The notches n a are formed at a distance from the end of the wire equal to the length of one nail, and the block L is of suflicient depth to contain the portion of the wire below` the notches a a. 1t will be seen, therefore, thatwhen the block L is in position to cause its IOG orice M to coincide with the'oriiice Kot the block H, as shown in Fig. 5,'and the wire P is -inserted 'in both of said orices, the wire is i by the cutters of the metal not removed in forming the notches, hence the points of the nails are not made wider than the diameter of the wire. It will also be seen that by moving the block L, after the notches a n are formed, the thin neck between said notches will be severed thereby, severing the portion of the wire contained in said block, and at the saine time completing the chisel-point on the end of the wire in the fixed block H, as shown in Fig. 6, the surface formed by the breakage of the thin neck eonstitutin g the apex of the chiselpoint. The severed portion P of the Wire now constitutes a completed nail, its head or outer end being completed by the severing of the neck, and its cliisel-point having been previously formed by an operation similar tol that above described.
This improved method of forming nails from continuons wire differs from methods heretofore employed in forming the beveled sides of the chisel-point by cutters moving parallel with each other and having a planing action. Heretofore the wire has been indented at a distance from its end to form the point ofeach nail by cutters moving toward each other, said cutters displacing the metal so as to make the points wider than the diameter of the wire. It is obvious that by my improved method a more perfect point is formed, the point being of the same width as the diameter of the wire.
I form on the under side of the fixed block H a wedge-sliaped rib, R, fitting closely in the space between the cutters N N, and intersect- Ved by the orifice K. The ends of said rib, on
either side of the orifice K, support the wire laterally between the proximate surfaces of the blocks H L, and constitute a safeguard against the slightest bending of the wire under the inuence of the cutters at the point where the notches n a are formed. The cutters N N, after forming the notches n n, remain in contact with the wire until the block L has been moved, the inner side of one of said cutters constituting an edge or shear tovsupport the notched portion of the wire, and cooperate with the surface of the block L to sever the neck between the notches when the block Lis moved. The cutters N N are reciprocated by means of the cam D on the driving-shaft B, and a lever, S, pivoted at T to the frame A, and at T to the stock U, to which said cutters are attached. A spring, V, holds the upper end of the lever S in contact with the cam D.
The mechanism for feeding the wire P to the pointin g mechanism last described is composed of a pair of plates or feed-jaws, a a, lo-
cated on rods b b, which are adapted to slide in bearings in a bifurcated yoke or frame, c. The jaws a a may be coated with rubber on their proximate surfaces, or may have steel plates with grooved or rougheiied surfaces, the latter being preferable, and the wirel to be fed is interposed between said surfaces. Springs d d on the rods b b press the jaws a a against the wire and cause them to normally hold or grasp the saine with sulicient tightness to enable them, when moved toward the block H, to feed the wire into said block. The frame c is provided with a vertical arm, f, adapted to slide in a socket in the frame A. The frame c is pressed, by a spring, g, against the cam C on the driving-shaft, and is therefore reciproj cated vertically when the shaft rotates.
h represents a wedge located on the driverbar t', which bar is also reciprocated vertically by means of the cam F, a stud, 7c, from said bar bearing on the cam, and a spring, j, adapted to force the driver-loarabruptly downward when the cam passes from under the stud 7c. The wedge h is so arranged and the driver-bar i is so timed in its movements that when the feedjaws a a rise the wedge will also rise, and at the same time insert itself between and separate the jaws a a, so that during their upward movement they will not move the wire. Vhen the jaws a a have completed their upward movement they descend before the driver-bar, so that the wedge remains behind, and the jaws are caused, by their springs d d, to grasp the wire and feed it downward into the blocks H and L. The length of movement given to the wire, and consequently the length of each nail, is determined by a sliding wedge, l, on lthe frame A, said wedge constituting an adjustable stop for an arm, m, on the slide f, and limiting the downward movement of the slide f, the frame c, and the feed -jaws a a. When the operator desires to change the length of the nails he moves the wedge Z in one direction or the other, thereby permitting the slide j' to descend more or less. The wedge l may be moved by the operators foot through a treadle and suitable intermediate mechanism, so that the length of the nails may be varied While the machine is in operation.
n' represents a guide, through which the nails are driven by the driver t", rigidly attached to the driver-bar t', into a boot or shoe held on a suitablejack (not shown) under said guide. The movement of the block L, whereby each nail is severed or broken from the wire, is effected by the cam E and intermediate mechanism, consisting of the pivoted lever E and the connecting-rod E2. cient to cause the orifice M of said block L to coincide with thev guide n', and thus present the nail to the driver i.
For the purpose of feeding the sole as it is being nailed, I employ a feed-dog, p, pivoted to the lower end of a bent lever, i", and arranged to bear upon the sole when the saine is held in position to receive the nails from the Said movement is suffi- IOO IIO
guide-orifice a. The lever r is pivoted at s to the trame A, and is provided with an inclined is moved in the opposite direction the teethv will engage with the surface of the sole and move the latter. The inoperative movement of the feed-dog is effected by the downward movement of the driver-bar i, and the operative movement by the upward movement of .said bar; hence the feeding movement of the sole is effected after each nail has been driven. W'hile the inoperative movement ot the feeddog is being effected the nail is entering the sole from the guide n', and is not completely driven until said movement is completed; hence the partially-driven nail prevents the sole from being moved during the inoperative movement of the feed-dog. By operating the sole-feed directly from the driver-bar, as described, I obviate anyliability of change in the relative movements of the feed-dog and the driver-bar, such as might occur if the feed-dog were operated directly from the driving-shaft.
The operation of the described machine as a whole is as follows: The blocks H L being in the position shown in Figs. l, 3, and 5, the wire is fed into the orifices in said blocks and held frmlytherein. The cutters N N then advance and form the notches n n on the wire, the cuttings removed by the cutters being ejected through an inclined spout, w, formed in one of the supports 1. The block L is now moved forward, severing the nail, as previously described, and when its orifice M coincides with the guide n', as shown in Fig. 6, the driver-bar 2'., which has been previously raised, descends, bringing down the driver'z", which drives the nail through the guide n into the sole below. After the nail is thus driven the block L is moved back until its orifice M coincides with the-orifice K; and when said orifices coincide the feed-jaws a a, which were raised Y while the block L was moving back, descend, and again feed the wire, as above described. The cutters N N move back before the wire is fed, so that they leave the orifice K unobstructed for the passage of the wire into the orifice M. The opera'tion is thus repeated as long as desired.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, isi- 1. In a sole-nailing machine, the above-de scribed means for converting wire into chiselpointed nails, said means consisting in a fixed block, H, having an orifice to contain the wire, a pair of chisels reciprocatin gin guides formed in the block H, adapted to remove metal from opposite sides of the wire, thereby partially forming the point of one nail and the head of the preceding nail, and a movable blockLL, having a wire-receiving orifice adapted to coincide with the orifice in the fixed block and assist the latter in holding the wire and to be moved laterally after the action of the cutters to sever the wire, and thereby complete said t head and point, as set forth.
2. The combination, with the fixed bloclrH andthe movable block L, having the wire- Yholding orifices, the cutters or chisels N N, havving planing cutting-ed ges to form notches in the opposite sides of the wire held in said orifices', and adapted to remain stationary in contact with the wire when the block L is moved, thereby supporting the notched portion ofthe wire and co-operating with said block L in severing the neck of wire between the notches, as set forth.
3. The combination of the finedV block H,
having the guide-orifice K, the reciprocating notchin g cutters N N, the movable Lblock L,
having the oritice or holder M, the driver t', the fixed guide-orifice n', through which the nails are forced by the driver i', and mechanism for reciprocating the movable block, whereby its orifice or holder is alternately caused to coincide with the orifice K to hold the wire while it is being notched, and with the orifice n to present the nails to the driver i', as set forth.
4. As a means for holding and notching the opposite sides of wire in a sole-nailing machine, the combination ot' the fixed block H, having the wedge-shaped rib R and the guideoritice K, terminating in said rib, the movable block L, having its upper surface in close proximity to the outer edge or apex of the rib, and provided with the guide-orifice M, adapted to coincide with the orifice K of the fixed block H at stated times, and the reciprocating cutters N N, separated by a wedge-shaped space closely fitting the rib R and adapted to form notches a n in the opposite sides of wire held in the orifices, as set forth.
5. The combination of the fixed block H, having the wire-guide M and cutter-guides N N', the cuttersN N, fitted closely in said guides, and the inclined channel w, formed in the supports on which the block H rests, for the escape of the cuttings removed by the cutters lN N, as set forth.
6. The wire-feeding mechanism consisting of two opposing separable jaws, a a, pressed against the wire interposed between them by springs and mounted on an intermittently-reci procating yoke or frame, c, combined with a wedge, h, on the driver-bar reciprocating in- IOO IIO
press said feeddog against the sole, as set forth.
