MACHINE FOR PEGGING BOOTS AND SHOES.V

Specification of Letters Patent No. 10,407, datedl January 10, 1854.

To all 'whom #may concern.'

Be it known that I, HALvoR HALvoRsoN, of Hartford, in the county o-f Hartford and State of'Connecticut, have invented anew and useful Machine for Begging Boots orv Shoes; and I do hereby declare that thesame is fully described and represented in the following specification and the accompanying drawings, letters', figures, and references thereo-f. Y

Of the said drawings Figure l denotes a top view of my said machine. front elevation of it. Fig. 3 is a rear elevation of it. Fig. 4 is an elevation of the right end of it. Fig. 5 is an elevation of the left end of it. Fig. Gis a vertical, central, and transverse section of it.

In the said drawings A represents the main frame for supporting the operative parts of the mechanism, which frame may be of the form as exhibited in thedrawings, or it may have any other proper one.

The boot or shoe to be pegged is to be securely fastened with its sole vupward in a horizontal rectangular frame B that is supported on another frame C and so as to be capable of being moved transversely forward or back between parallel guides D, D, fixed on such frame C.

During the operation of pegging a boot or shoe and in order that the edge of the sole may always be brought into correct position with respect to the pegging awls and during the movements of the shoe under them it is found that the general form of soles requires that the boot holder should not only have vertical and transverse but longitudinal motions. For this purposexthe frame C is sustained between vertical and parallel guides E, E, and it has a stud or dinallyof the machine and on a supporting rail G of it as seen in Figs. 2 and 3. From the back of the'frame B a projection H extends and is made to act against a curved guide I afhxed firmly to the frame of the machine. The longitudinal movements of the carriage or frame C is produced by a long screw K that is arranged as seen in the drawings and works through a female screw formed in a projection L from the rear side of the carriage C. During the movement of the carriage C by the screw which takes Fig. 2 is av place whenever the screw is put in rotation thefcarriage C will lhave not' only a longitudinal Vmotion, but a vertical one as it passes over the sinuosities of the pattern or guide F. Theweight of the carriage may be suiic'ient to keep it down onthe pattern` or cause it to descend into the hollows, lor a spring may be used for such purpose. Dur-V ing such movement of the carriage C, the frameB being moved with it has a transverse motion also imparted to it by means of the curved guide I against which the projection H acts, such projection being pressed against the guide by'means of a spring M,

.that is attached to the carriage C and made.

depth.

Above the main frame A` and working in transverse directions onvcenters as seen at N, O, is what I termthe rocker frame or swinging lathe P. F romthe lower part of an arm or frame @extended back from the middle of or making part of the rocker frame'P, a small projection or tracer R is made to extend and rests on acurved guidey or bar S attached to and made movable with the projection L, such guide being so formed as to cause the rocker frame tok rockv or move in its bearings to the extent required during the operation of pegging a boot in order to present the awls at the proper` angle with the sole to enter'it..` The POintsy of the awls which areseen at Va are Y arranged so thatv they may be within the axis of motion of the rocker frame when at `the extent of their downwardmotion, and as the boot vsole changes its position from time to time it becomes necessary that the position ory inclination of the awls shouldnbe v varied in order that they may enter the sole at the necessaryangle.y This will be readilyv seen by cord wainers or persons skilled vin the art of making pegged boots.

The awl or awls are made to extend downt ward from a plate or piece of metal b that is aflixedgto the underside of a punch c, thatk to turn around on a screw d which extends through the middle of the plate and up into the punch. The awls areV on one side of the center of this screw or are arranged ata distance therefrom. By turning the plate on this screw one hundred and eighty de-` grees the awls may be made tostand on the opposite side of the center of the screw.,

During the operation of pegging a boot the awls are made always to operate in advance of the pegs driven in, they being so arranged that there shall always be one or more holes made in the sole between any one being made by the awls and the nearest pegs that aresimultaneously being inserted. 'As the awlsmust always act in advance of the pegs inserted itbecomes necessary in-reversing the lateral movement -of the boot that the plate in which the awls are held should be first turned around one hundred andjeighty degrees. When to peg from heel to toe of the boot the awls should stand on one side of the 'screw (Z. When we peg from toe to heel they should stand at one hundred and eighty degrees distant on the opposite side of the screw cl. This will'be more readily seen after a description of -theremainder of the machine. 7 i

The rocker'frame P ismade to carry one, two, or more troughs g, L., such number being in accordance with the number of awls.

These troughs are placed parallel to each other as seen in Fig. 7 which is a top View of them and the slide 0r carriage which is placedbetween them as well as of such parts of the rocker frame Pf and machinerythereof as are below the awl holder. Each trough is made of a suitable depth to receive a strip of wood from which pegs are to be cut. Between the two trough 9,7, is a slide or carriage 1J which has a rack of teeth 7c made on its upper edge. From each side of the carriage, a projection U, (see Fig. 8,l

which is an end view of the carriage g) is made to extend over and down into the adj a-` cent trough g or la., and so as to rest against the outer end of the strip of `wood `when placed in the trough. When this carriage is advanced or moved toward the middle of the machine it forces the two strips of wood along with it. The movement of the carriage is effected by means of a drawv pawl m that is jointed to the lower end of a pendulous rod or bar n that turns on a joint at 0 and in a plane parallel to that of the frame P. The bar n is moved inward by a cam 0 fixed on the side of a wheel orpulley p that is placed on and attached to the shaft T. The outward movement of the rod `or bar n is produced by the reaction of a Iparted to it, that isto say, it is first moved upward sufliciently to cause the knives 7", r,

1r, to cut from the strips of wood projecting out of the troughsg,V h, two pegs, one of which will be held-between the first and second of the knives, while the other is held between the second and third of the knives, and this by friction or simple springof the knives, it being understood that the strips are so arranged in their respective ends that only Vone peg from each will be taken `during such upward movement of the knives. Next the knife "carrier is moved forward with the pegs and so as to carry the pegs directly over the holes in the sole into which they are to be driven at the next descent of the punch and its awls and by pressure of the turning plate b, of said punch 0, upon them. The lifting upward of the knife carrier is effected by means of a bent slide rod u that hooks under the carrier, while at its upper end it is bent as seen in the drawings. During each revolution of the 'shaftT' a Ipin or projection-fu from the side of the pulley p passes under the bent upper part of the rod u and lifts the rod upward so as to raise the knife carrier.

The knife carrier is jointed to a. frame or carriage w that slides forward and back and is supported between ways fr, that extend back'from the frame P. A swinging bar y at its lower end passes through a slot made in the carriage fw; while at its upper end it is suspended and plays on a joint pin e. To this bar jz/ another bar a is jointed at its rear end while its front end is hooked around the front edge of the connecting rod V (hereinbefore described) such extension in front of the said front edge be`` ing such as will cause the bar a to be moved forward with and by the connecting rod V whenever 1t 1s so moved. Such a forward movement will of course cause an advancement or forward movement of the knife 'Ihe rotary movement of the screw K is produced by Vmechanism which may be thus described: On the right end of such screw is a cogged or lantern wheel c] which acts in concert with one or the other of two lifting pawls cZ, e, which embrace iton opposite sides and are made and connected together at their upper ends and supported so as to play or swing freely on a common center or pin f extended from the middle of the lever g all as seen in the drawings. This lever works up and down on a fulcrum or pin 7L at its rear end, and is jointed at its front end to the lower end of a connecting ro-d i', whose upper end is placed on a crank pin le projecting from the side of a wheel Z that is fixed on the outer end of the shaft T.

To the lever g two springs m n are affixed, one being of more elastic power than the other: Vhen the spring m is brought against the lifting pawl d it presses it against the teeth of the cogged wheel 0, during which time the other spring (n) should not be allowed to bear against the pawl e, but should it be desirable to throw such pawl into action with the teeth of the gear it will only be necessary to bring the spring n to bear against it, when the elastic po-wer of the spring n will throw the pawl into gear with the wheel and the other pawl out of gear with it., Consequently, during the revo-lutions of the shaft T the screw K will be revolved in either direction according to which pawl may be acting against the cogged wheel. By throwing both pawls out of gear with the cogged wheel the screw may be revolved by hand applied to a crank a2 fixed o-n the opposite end of the screw, and thus by means of such crank the cai riage B may be moved at any time into any desirable position.

The awls are not to be arranged at the distance from the peg knives or cutters equal to that of one peg from the next succeeding one when they are directly over a boot sole, but they are arranged at doublesuch distance, in order that there may always be an empty hole between the awls and the pegs when undersuch circumstances. The utility of this empty hole in reducing resistance to the entrance of the awls into the sole will be easily obvious, as this can be readily demonstratedl by taking a piece of leather'and two awls and proceeding as follows, viz: First insert the two awls in the leather allowing one to remain thereafter extracting the other. f Next insert the second'one again in the leather at the same distance from the second hole that such holeV was from the first one. Next without bending the leather, withdraw the two awls; and look through the three holes. The awl will not only be found to'entereasier into the third hole than it did in the second one, but

`or tracer H and return springk the middle hole will be found to presenta spongy or rough appearance on its inner surface, while the others are smooth and polished. The rough hole will hold a peg firmer than the smoothone. p Y yHaving thus set forth my machine what I claim is 1 l. The automatic combination constituting the same and composed of the following elements, or their mechanical equivalents; l, a frame or boot holder B; 2, machinery for moving the boot holder B horizontally in directions both toward and away from the awls or hole making contrivances, or in accordance with the horizontal or peripheral curvature of the sole, such mechanism being the guide I and bearing point M; 3, ma- .chinery -for raising and depressing such boot holder in accordance with the vertical curvature of the sole, such mechanism being y the guide or cam F, and the second frame C, with its tracer F; 4, mechanism to give the boot its movement from heel to toe or Y vice versa, under the awls or pricking machinery; such mechanism being-the screw v K, cogged wheel c', pawl cl, Vor e', lever g', connecting rod i, and crank pin k on shaft 7c. 5, machinery for holding the strip or strips of wood from which the pegs` are to be cut and regularly'advancing such strip or .strips in manner required toward the cutters, the same consisting of thetroughs pricking machinery; 7, machinery "for pricking the holes in the sole for the reception of the pegs; 8, machinery for pressing or forcing such pegs into these holes, such' being accomplished by the plate, Z7, carried and forced down by the punch c; 9, a rocker frame or swinging lathe I made to sup-y port and carry the mechanism above denoted as the fifth, sixth, seventh `and eighth elements of combination; 10, machinery for giving or imparting to such rocker frame its proper movement to insure thecorrect direction of the awls in puncturing any hole or 'holes in any part of the sole, suchina-` chinery being` the movable guide andthe tracer R, theV latter being attached to the rocker frame.

2. And as auxiliary to awl holder b made capable of being, turned around substantiallyin manner and for thel the above or 'as an t i improvement I claim the reversible, plate orV the machinery that cuts the pegs from the strips of wood and brings them forward and forces them nto the holes, that there shall always be one or more holes made in the sole between the pegs that are being driven and the holes that are being simultaneously made in the sole.

In testimony whereof I have hereto set my signature, this second day of March,
