IMPROVEMENT IN MACHINES FOR PEGiGING BOOTS ANDSHOES..

Specification forming part of Letters Patent No. 10,427 dated January 17, 1854 ;Y Reissue No. 269, dated July 4, 1854; Reissue No. 701. dated April 26, 1859. l

To all whom it may concern:

Be it known that l, J oHNJAMEs GREEN- O'UGII, of the city, county, and State ot' `Yew York, have obtained Letters Patent of the lUnited States, dated the 17th day of January,

l 1854, for several inventions' in Shoe-Pegging Machinery, which I 'now desire to separate, :and to have reissued to mein several distinct patents; and I do hereby declare and ascertain one of my said inventions contained in said Letters Patent, referring to the aecom- 'panying drawings in whichi Figure 1 is a perspective view of the machine; Fig. 2, vertical section; Fig. 3, plan from below; Fig. 4,awl and peg-stock detached Fig. 5, modiication; Fig. 6, front view of peggingstock, Src.; lig. 7, modified section; Fig. 8, peg-wood; Fig. 9, peg-feed Figs. 1i), 11,112, peg-cutters.

My invention relates to the method of holding the shoeor boot during the peggi'ng operation and moving it to the pegging appa-ratus in the line of the intended row of pegs; and the iirst part of my said invention consists in connecting the last with an apparatus so that the last may be turned and moved in any desired direction in a horizontal plane,

' that everypart of the line on which the pegsv are to be inserted, whatever that may be, may be brought in succession to the pegging apparatus, when this is combined with a mechanism which tends constantly to force it upward against a rest or guide, but which will permit it to yield downward, that the sole of the shoe or boot may, as it moves along, continue inl contact withfthe rest or guide, however the sole may vary from a plane and the last part of my said invention consists in moving and guiding the last or holder automatically, to present every part of the sole to be pegged in succession to the pegging appa` ratus, and in the line of vthe intended row of pegs, whatever that may be, by means of a guide-groove,z, and guide, anda pinion en gaging the cogs of a rack, in line corresponding with the form of the guide-groove, or nearly so, when this is combined with the table having the capacity oi' universal movement, as above stated. 1 l

'The drawings, Figs. 1 andy 2, show a table, a", sustained on an upright spindle, a', supported ou the end of a horizont-al lever, b',

which is weighted on the opposite end to counter-balance the 'shoe-holding apparatusk with sufficient force. against the point Awhere the shoe is to be pegged, and resist the force of the awl and peg-driver. On the top of they table are plates which slide in` grooves at right angles to each other, so as to allow the top plate, a2', a motion in every direction horizontally, or by merely resting this top plate, a2, upon the plane surface of the table it can be slid in all directions upon the table a. The top plate, a2, has the shoe-clamp aiiixed to it, which may have motion thatis calculated to present the shoe in an inclined position as'required for pegging properly, inclini'ng the pegs inward, or the stock` forpeggingmay be made to slide in inclined ways for the same purpose. l

To attach the shoe readily to the clamp, I form a lhole in the last at f, in which a stout .Steel pin is .inserted that is affixed tothe clamp, and a sliding piece, g, is driven under the toe of. the shoe by means of a wedge, screw, or other suitable device. This causes a binding action upon the pin at f and firmly fastens theA shoe. It is obvious that if the pin were to slide or swivel so as to bring the toe of the shoe rmly down upon the ,toepiece the same effect would be produced.

If the shoe is .movedl by any apparatus acting upon the shoe i.tself,nofurther machinery tends up through the hollow mandrel, and its upper end enters the groove. Upon this' shaft c there is a pinion, c3, the teeth of which gear into the eogs upon the plate, so' that by turning the pinion the groove will be made to pass along vover the shaft and be guidedby it. c', and is aiiixed byits lower end to the lever b', so that itcannot turn. 0n its upper end it A tube, c', surrounds the shaft'.

bears a'short horizontal arm that projects beyoud the pinion, and a gnidepin, e, outside. the pinion and at avsuiicient distance from the end of the shaft to guide the course and turn ingr ofthe shoe, projects up into the groove, l eeping two points of the groove e* and c', (see Fig. 2,) always in the same relative position in relation to the stationary parts ofthe machine, and causes the carriage to turn upon the groove-curves. The shaft c' above named projects below the lever b', on the lower end of which there is a ratchet-wheel with pawl andclutch attached to a horizontal lever, c,

by which the shaft and pinion are worked in one direction, at intervals, by means of the reciprocating mot-ion of the lever produced by its connection with the moving parts. This may be effected in the following way; An axis, c3, is placedA horizontallyunder the plat- E form or table a', to .which are attached arms at right angles to each other. The vertical arm is connected by a rod, it, with the lever c, while the other arm l is connectedA either with the pcgging-stock or other moving part so as to be vibrated, and thus move the upper plate of t-he carriage at intervals, leaving it at rest when the awl and peggingstock descend to drive the peg.

' AIt will beobvious from the foregoing that the first part of my said invention may be applied independently of thek means above described for moving the last automatically, by substituting any other ecient mode of feeding and, guiding or by performing the feeding andg'uidinghmovement by hand, and

therefore l do not wish to be understood as limiting my claim. of`invention Ato the employment of the several parts of my said invention in connection. A

The apparatus for forming the pegs and feedingthem intothc driving apparatus consistsof a trough, through which strips of wood are fed, made like the ordinary'pegs used in shoe manufacture, but only split od 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 pegwood is fed forward at intervals, the breadth cfa single peg at a time, by

a feed that is perpetual, or such as will feed anr infinite series of vpegs in succession. This may be effected by a variety of apparatus-L- such as feed-rollers, or a feed-roller and spring, or an endless screw working into the .lower serrated edge of the peg-wood, or'by a device shown in the drawings at Fig. 9,.a1l of which are well known endlessfeeds, and are but the equivalents of each other.

The device shown at Fig. 9 is a reciprocatwing. feed, in which m is the trough through which the peg-wood n passes.- '0n this trough,`

or beside it, there is a slide, t, that ,is made to slide by 'a vibrating lever, ,tothe" lower end lofwhich it is attached by e connecting-rod. The levers is 'vibrated by the; upward and j downward motion of the pz'ng-stoek, (which wllbe'hereinaf ter descri so that when the pegging-stock risel, :the pegwood isfed forwardl and ont on', readyto 'be driven as the peggingls'tojck descends. I o cut the pcg` properly a cutter mstpa'ss through it ina line perpendicular to the' top and `bottoni lnes o t the'peg-stri'p and at right angles to the side thereof, the cirt being made from side to side throughl the peg-strip without regard to the course of the grain of the wood. This cnt may be made by forcing c. knife having an inclined back downward, so as to cut across the peg-wood, as seen in Fig. ll, in which a is the cross-section of theI peg-wood ,.p, the

knife in position before the cut is made; a',-

dottedl lines showing the cut made.

Fig. 12 shows a modification, in which the vedge of the cutter is inclined, which performs a' somewhat similar action by being pushed downward into the position shown by dotted lines. i Another mode is to force the edge of a knife that is parallel with lthe side ofthe peg-strip straight forward across it in a plane lofmotion at'right angles thereto, as seen in Fig. 10, the dotted line showing the range of motion. The combined action of these parts is, first, forcing forward the peg-wood intorthe recess; and, secondly, cuttingo'with .theknife, which is actuated by a cam, crank-pin, or eccentric, from the driving shaft. driver and awl for making the holes and inserting the pegs'may be on separate stocks and driven alternately; but I prefer to put them both into one sliding stock, which is made to slide up and down in theframc or standard of the machine.

In Fig. 1,11 a is the base of the frame, from I which rises lthe standard b, that at its upper end projects over suiciently at c to hold the slide that pegs the shoe, and above the slide is the drivin g-shaft h, from whichl all'the parts are moved. On this shaft there is an eccentric, or crank, or cam, g, (the latter is shown in the drawings,) of any style known, that will give the desired motion, which maybe regular-like a simple crank, or eccentric or irregular. This latter can be effected by the cam seen in Fig. 1, or by a grooved cam, and this irregular motion I prefer; but it is essential .that the mot-,ions up and down should be positive and controlled in their range, forcing down the awl and peg to the precise point and drawing them back to a proper point at each action. The awl and peg-driver stock is shown at Fig. 4 detached. At Fig. 5 amodil ficatiou is seen. The. peg-driver d plays up and down in the recess o, Fig. 6, into which the peg-strip is fed, when the peg-driver isl raised and the pegis ythen cut oli', (or it may' havey been previously cut om) andas the pegdriver descends it forces the peg'dowu through the sole of the boot or shoe into the hole previously made for'itby the awl.,

The device for moving the shoe by the awlV requires the' awl to ydescend down into the sole at a snicient distance from t-he preceding Apcg to set the next pega. vWhen the awl is drivenpnto the sole, the stock is moved sidewise by a. cam or other equivalent device. The

stock may either slide sidewise or turn' on an' arm of sufficient radius to change the'angle' of the awl but-little. Fig. 4 shows the first, andFig'. 5 the second, method. The slide i movement 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 the sole inline with the pegwhen driven-the' effect being the same whether the sole is carried along straight or is swiveled'to peg round a. curve, the motion f the shoe being entirely dependent upon the an] as a center.

\Vhat; Iclaim as my invention, and desire to secure by Letters Patent, is

1. Connecting the last with a horizontal slide or plate capable of presenting the shoe orboot,

substantially as described, so that the shoe or boot attached tLereto may be turned and moved in any' direction in a horizontal or inclined course, in combination. with` a mechanism, substantialbv such as described, which tends constantly to force it upward against a restor guide, but which will permitl .it to yield downward, as described; but this combination mechanism above described, or any equivalent -therefcr.- 2. As an automatic means of movingan guiding the last to present it tc the Begging apparatus in the required line of pegging, the

l guide-groove and guide, and pinion and curied rack, substantially as described, in "combina the equivalent thereof, which permit the last tc`be moved in an)T desired direction as. set forth.
