KNOW-ALL MEN Br THEsE'PREsEN'rs; i

That I, HENRY C. STONE, of Brookfield, in the county of Worcester,- and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Pegging Machincs,of which the following is a full, clear, and exact description, reference being had :'to'the accompanying drawings, forming a part of this specification, in whichi Figure 1 represents a side view of so rauch of the pegging machine as isncccssaryto illustrato my invention.4

Figure 2 represents a front view ofthe parts shown in fig. 1. i i

Figure 3 represents a section on line A B,-iig. 1. i

Figure 4 represents a section on line GD, same figure. V

Figure 5 represents upon an enlarged scale a sectionon line E F, and p i Figures 6 and 7 are longitudinal sections on line G IjI, as will be hereafter` explained.

The line of vision in all the cross-sections is indicated by the arrows in iigs. 1 and To enable those skilled in the art to which my invention belongs tomake and use-the same, I will proceed i to describe it more in detail. i i

In the drawings, the part marked A represents the stand, which supports the other parts of the pegging device shown in the drawings, and which refers more particularly to the mode of feeding the' pegs.

As many parts of the device are wellsknown, and in general use, it 'will not be necessary to describe them in detail, and I shall therefore confine myself more particularly to nay-improvements uponthc machine, which has for its object the changing of the machine to feed pegs of different lengths, at the will of the-operatori The part B is the peg-wood table r carriage, which has heretofore been made with a single groove, a, and l one pair of feed-rolls, 'b Z1, to feed a single sheet, c, of peg-wood, the operation being as follows: By means of a shaft, A', and eccentric, A, a vibratory motion is impartedl to thc arm B', hinged to frame orstandlAby a i bolt or journal, B, and Vtothe lower end of which the feed-table or carriage B is attached, so that at each vibra`- tion of arm B the table or carriage B will bc swung toward the stationary `knife C, attached to knife-arm C', the upper end of' which is fastened to the projection C" on the front of' stand A.` By the outward motion o f the l carriage B a peg is severed or split dfrom the sheet, and by the inward motion of the carriage the feed-rolls b b are caused to feed the sheet c along a sufficient distance to form another peg, which is split olf at the next out ward motion of the table. The motionsoi' rolls b are obtained as follows: Upon the under side of the carriage B is an arm, D, which is fastenedfto the stand A, and is consequently stationary. To the top of arm` D a pawl, 1, is attached, and so arranged as to take into the'ratchet-wheel 2, fast upon the shaft or journal 0f one of the feed-rolls said rolls being geared together at the bottom' so as `to both move'together. It will be seenthat when table or carriage isswnng ont as above described, the pawl lwill be drawn in by spring, le, i so as' to take into a new notch in wheel 2 when the carriage is swung back, and thus cause the aatchct-whecli and feed-rolls I) b to heturned a snicient distance to move the sheet of peg-wood the thickness of a peg. After` the pegs pass the knife C they enter pcg-guides E E', which conduct them in regular order as they are slid along by the action oi' the feedrolls b e upon the sheet of pegiwood c until theyreach thcdrive-tuhe F, which has a hole,f, through i-t for the playof the driverywhichis arranged to work above the tube, and at `the proper time descends and drives the pegs iiitothe sole offthe hoot or shoe in the ordina-ry man ner. Y' i Such, in brief', is a general description of the machine as nscd prior to my invehtiolnwhich I willxnnow explain.

` In lieu of one groove a in the carriage or tabl-e B,\I make two ygrooves o: a', and in .the latter is placed a sheet of peg-wood, which is fed forward at the proper time by, a set of feed-rolls, b (1', which are geared at thc bottom the sonic as rolls b Il, and are mov-.ed bythe action of' a .pawl, meeting upon the ratchet-wheel 3. Thq pawl y is attached to arm D, and is drawn towards thc ratchet-wheel 3 by spring c. As only onc sheet of pcgwood or length of pegs is tohe fed' to the .machine at a time, I will now'explein how the machine is adjusted to -iccd either length .ot'pegs', and that,`too, `withontstopping thc machine. Under` the pawls 1 andy is a bar, G, f haring two pins, il 5, which project np by the inside of the pawls 1 and 9, as fully ,indicated in the drawings. i Said bar G isiittcd toslidc in a groove in the arm l), or in proper guides attached thereto. Tothc rear end of bar G is hinged one cnil of thc connection Y1, the other cud of said connection being hinged to 'plate 1', thc inner :nd of which is fastened to the stand A. The connection It is attached to the shipping-lever I-I by-mcans of the :onnecting-bar I, one end of which is hinged to the connection L, whilethe other end has a slot into which pin ion lever H ts. Lever H issupported upon an arm, 7c, fastened to the arm B', 'and is provided with a pin, 7, Jzhich iits into the lslot 8 in the lever H, as fully indicated in iig. 3. The inner end, 9, of lever H is hinged to i lug, 10, upon the switch J, which forms the front part of the carriage or table B,but is so made that its front and can be rocked or movedback and forth, so as to bring either of the grooves a a upon a line with the single groove m in the peg-guides E E. The rear end of the switch J has a tongue, 11, which fits into a correspondng eoncavity in the table or carriage B, while the frontof the switch is rounded o' to enable it to play close 1o thefends of the peg-guides E E without'binding. It will be seen that when lever H' is drawn forward nto the position shown in red lines, the effect is to throw pawl 1 out of action andbring pawl g into action, vhile switch J Yis moved Vto bring the groove a upon'a lineY with groovem, lso that so long as the parts remain n this position short pegs will be fed to the driver. The position of the several parts when thus. operating is shown in red lines in the drawings. It will be observed that the ends of slot 8 are made in such form that there s no danger of lever H- slipping out of place when once adjusted, and as the stand or arm is attached to the ribrating arm B', lever H Swings with the table or carriage B. K andl L are adjustable top guides for sheets c of-peg-wood. These guides can be set up or down to suit sheets of different widths. For the purpose of 'etaining the pegs in proper position as the;r are passed through the pegfguides E E under the driver, the guide l` is recessed out on the inner side, as seen vat n, and a curved guide-piece, o, is 4fitted in to work iu said recess, )eing forced forward into the position shown in dark lines, fig. 5, by a spring', p, plaeedsbetween the front of the )eg guide-piece E and the frontside of the piece o, the spring being kept from end play by the pins y y, which ilso retain the vguide-piece o in proper position. The pins work through the front of the peg-guide piece E, tud have heads on their outer ends, as fully shown in clark and red lines, iig.' 5. The front end of the guidc- )ieee o is made thin, or is bevelled olf, as shown at s -in iig. 5, so that when pegs of' full length are fed forward yhey pass back of the bevelled edge s and force the guide out, as shown, in fig. 6, while, when short pegs arc fed 'o rward, they pass under the guide-piece o, as shown in Eg. 7. p

My improvements are of great utility in the manufacture of'boots and shoes in which shorter pegs are equired in the shank than upon the sole, since all that the operator has to do is'to adjust lever H, as 'before `tated, in order to 'have long or short pegs fed to the driver, and in a very-short time he will learn to adjust the ever at the proper time to have what pegs may be in the peg-guides E E used up before theehange is desired o be made in theA shoe or boot.

Those skilled iu the art to which my invention belongs will fully appreciate thegreat advantages to be lerived by the use of my improvements, both as regards time, wear of lasts, 'and character of work. The parts nay be constructed in any desired manner.

Having described myimproved pegging machine, what I claim a's new, and desire to secure by Letters 1. The combination, with the peg-wood carriage or table B, having two or more grooves a a', or their equivtlents, ot' a switch, J, substantially as and for the purposes set forth.
