IMPROVE-MENT IN MACHINES FOR: PEGGING BOOTS AND SHOES.

Specification fom1`ng part of Letters Patent No. 10,427, dated January 17, 1854, Reissue No. 269, dated July 4, 1854 Reissue No.699, dated April 26, 1859.

.To all whom t may concern.-

, Be it known that I, Jol-IN JAMES GREEN- OUGH, of the city, county, and State of New York, have obtained Letters Patent of the United States, dated the 17th day of January, 1854, for several inventions in Shoe-Peggin g Machinery, which I now desire to separate and to have reissued to me in several distinct patents 5' and I do hereby declare and ascertain one of said inventions contained in said Letters Patent, referring to the accompanying drawings, in which- Figure 1 is a perspective view of the machine; Fig. 2, a vertical section; Fig. 3, a plan from below; Fig. 4, an awl and peg-stock detached; Fig. 5, modifications; Fig. 6,.a'front view of pegging-stock, &c.; Fig. 7, a modified section Fig. 8, peg-wood Fig. 9, peg feed; Figs. 19, 11, 12, peg-cutters.

My improvement herein described is for the purpose of feeding the hole in the shoe forward into exactposition to receive a peg in the operation of pegging, so as to peg around the sole of a shoe of any form, or in any direction across it that may desired.

Before my Ainvention various independent means had been attempted for feeding or moving the shoe to be pegged, but none were surticiently accurate in executing the work with rapidity, and in all cases of which I have any knowledge mechanisms more or less complex were used independent of the apparatus for punching the holes and pegging. My mode of feeding is by the use ofthe awl that forms the holes into which the pegs are inserted, and moves the sole to bring each hole in succession when made directly in line to receive the peg before the awl is withdrawn from the sole. It will be obvious that if the shoe were moved by any other means than the awl while in the hole into which the peg must'be driven that any turning of curved work or any want ofadjustment between the feed apparatus and awl and peg driver would affect the result, and propably prevent the machine from working, beside complicating the machine.

The mode of application which I adopted is as follows: The peg-driver and awl work in concert. They may be put into two sliding stocks, but I prefer that they be inserted into one. This stock has an up-and-down motion, given to it by a cam or other analogous device, so as to drive the awl and peg at the same instant into the sole of the shoe or boot. In addition to the lip-and down motion, I give the awl a lateral motion, or a motion sidewise at right angles to the puncturingmotfon, or nearly so, movingit si dewise by any suitable device, such as a cam or crank motion that shall move it steadily and positively. The movement of the awl is as follows It is driven down into the shoe, then sidewise, carrying the shoe with it a sufiicient distance to spaceoft the distance between the pegs, then rises or is drawn out of the shoe and returned back to its first position, leaving the hole it has just made directly in line with the peg that is to be driven; and it will be perceived that this effect is to be produced whether the pegs are inserted in a straight ,line or in a line curved in any direction, as the sole vis swiveled on the line for inserting the pegs as an axis of motion. effect this very desirable object it is also necessary to move the peg-driver out of the way to enable the awl to bring the hole in line with the peg-driver, and then back again to the position where the awl was when itA left the hole, in order to place the peg in proper position to drive. This may be done by uniting the two that they may move in unison, or by drawing the latter back. I prefer the former way, and' have so represented it in the drawl ings. I

The construction is as follows: The apparatus for forming the pegs and feeding them into the drivin g apparatus consists of atrough,

m, through which strips of wood are fed, made like the ordinary pegs used in shoe-manufacture, but only split off one way, so as to present a series of pegs in a row (as seen in Fig. 8) attached together in a strip. The strip of peg-wood is fed forward at intervals, the breadth of a single peg at a time, by a feed that is perpetual, or such as will feed an innite series ofpegs in succession. This may be effected by a variety of apparatus-such as feedrollers or a feed-roller and spring, or an endless screw working into the lo wer serrated edge of the peg-wood, or by the device shown in the drawings at Fig. 9, all of which are wellknown endless feeds, and are but the equivalents of each other. The device shown at Fig. 9 is a reciprocating feed, in which fm. is the trough through which the peg-wood 'n passes.

0n this trough,.or beside it, there is a slide, t, Athat is made to slide by a vibrating lever, s, to the lower end of which it is attached by a connecting-rod. The levers is vibrated by the upand-down motion of the pegging-stock, heretofore described, so that when the peg-driver stock rises the peg-wood is fed forward and cut oft' ready to be driven as the peg-driver Vstock descends. To cut oif the peg properly a cutter must pass through it in a line p erpendicular to the top and bottom lines of the peg-strip and at right angles to the side thereof, the out being made from side to side through the peg-strip without regard to the course of the gra-in ot' the wood. This cut may be made by forcing a knife having an inclined back downward so as to cut across the peg-wood, as seen in Fig. 11, in which a is the cross-sec tion of the peg-Wood, b the knife in position before the vcut is made, c dotted lines showing the cut made.

Fig. l2 shows a moditication in which the edge of the'cutter is inclined, which performs a somewhat similar action by being pushed downward into the position shown by the dotted lines x. Another mode is' to force the edge ot' a knife that is parallel with the side ofthe peg-strip straight forward across it, in a plane of motion at Aright angles thereto, as seen in Fig. l0, the dotted lines showing the range of mot-ion. The combined action of these parts is, iirst, forcing forward the pegwood into the recess, and, second ly, cutting olf with the knife, which is actuated by a cam, crank-pin, or eccentric from the driving-shaft.

To move the shoe or boot by the awl, it i-s driven into thesole. The stock is then moved sidewise by a cam 0r other equivalent device. rIlhe stock may either slide sidewise or turn on an arm of sufficient radius to change the al'lgle of the awl a little. Fig. 4shows the first, and Figthe second, method. The sidemovement of the stock when the awl is in the shoe-sole carries the shoe along the same distance, and brings the hole thus made in t-he sole into line with the peg wh en driven, theeffect being the same whether'the sole is carried along straight or is swveled to peg around a curve, the mo- To hold the shoe and properly present the sole to be pegged, I employ what Idenominate a universal-Inovement 7 carriage or holder. This is designed to give the shoe all the necessary movements to bring each portion of the edge of the curved and undulating sole up to a stationary point to receive a line ot pegs all round. To effect this I employ a horizontal lever, bf, Fig. 2, on one end of which I support a standard7 ci', on the top of which standard there is ahorizontal plane, d. This is counterbalanced by a weight at the opposite end of the lever b', the fnlcrum being atA y2. On the top of this plane two slides, one above the other, have a motion 'at right angles toeach other,as clearly seen in Fig. 2, and on the top of the upper one the shoe is affixed. Now, it will be seen that if the lower plane has a revolving motion a movement in any direction can be effected, and, if there is a gage at g4 on the standard for the shoe to rest against, it will be kept in place while being moved by the awl, guided' by the operator in any direction.

It is obvious that if the plane had a motion up and down, and the plate on which the shoe was clamped could slide freely on it without guides, the same effect might be produced.

Having thus fully described my improve- 1n ent in feeding forward the soles of shoes and boots to receivethe pegs in the act of pegging,y what I claim therein, and desire to secure by Letters Patent, is

The moving the sole of the shoe along by means of the awl that forms the hole in which the peg is inserted, in combination with the peg-driver, whether'the peg-driver be or be not employed to perform the additional function of presenting the peg, whereby each llole made by the awl is brought in succession in line for inserting the peg before the awl is withdrawn, as set forth.
