button or anvil and illustrate the construev Beit known that I, PATRICK R. OoNDoN,

acitizen of -the United States, residing at Spencer, in the county of Vorcester and State ot' Massachusetts, have invented a new and useful Improvement in Pegging-Machines, of

` which the followingis a specification.

My invention relates to that. class of pegging-maehines which are ordinarily employed for automatically driving wooden pegs.

The object of my invention is to provide an improved construction for supporting and operating the horn of the pegging-maehine, and to provide means for au tolnatically trim ming or cutting off the ends of the pegs.

Tothese' ends my invention consists of the parts and combination of parts, as hereinafte'r described,and more particularly pointed out inthe claims at the end of this specification.

Inthe accompanying two sheets of drawings, Figure 1 is a side view, partially in section, of a suilicient part of a pegging-machine to illustrate the application of my invention. Fig. 2 is a partial front view illustrating one form of peg-driving mechanism which I may Figs. 3 and 4 are detail views of the the bearings 30 and 3l by means of suitable bearing-balls, as d. Secured upon the upper end`ot the spindle 32 is a hollow horn or arm D, having a button or anvil l5 journaled Surroundthehorn-spindle 32 is a coiled lifting-spring 33. The tension of the lifting-spring 33 can be adjusted in any desired manner.

As illustrated, I preferably provide an adjusting'nut 330, threaded onto the horn-spindle 32, and held in its adjusted position by means of a check-nut 331. At its lower end the horn-spindle 32 is loosely connected by a threaded piece 35 with a treadle-,rod 34. The

treadle-rod 3l is mounted in a suitable bearing 36 and is connected to a suitable treadle, as E.

Mounted inside of the horn-spindle 32,which is preferably bored out or made hollow, I provide a stationary spindle 37, which, near its upper end, passes loosely through a plate 38, carried bythe horn D,and is rigidly connected at its lower end to the treadle-rod 34.

' The spindle 37 is connected at its upper end with a train of gearing for holding the button or anvil B in a i'ixed position with respect tothe 'frame of the machine. As illustrated, this train of gearing comprises a gear 39, fastened on 'the spindle 37, whichmeshes with a train of gears 40, 4l, and 4&3. The gear forms part of the vertical rod 44,which is connected at its upper end by a universal joint with an inclined rod '16, which is provided at its end with a suitable bevel-pinion or gear-teeth which mesh with and engage the gear-teeth 1S upon the button or anvil B.

By mounting the horn-spindle 32 .upon ballbearings in the frame l have found in practice vbe no tendency of the spindle to cramp or bind in its bearings.

The peg-driving mechanism which l employ may beof any ot' the ordinary or approved constructions, and I have shown only such parts of the cooperating mechanism as will be necessary to an understanding of my peg-eutting devices.

l'teiferring to Fig. 2, lO designates a head or piece which is mounted so that it may swing or move transversely. vLoosely mounted in the head 10` is a vertically-movable slide 1l, having a piece 12 adjustably secured thereto, which carries the awl 13 at its lower end. Loosely mounted in the slide ll and extend.- ing through a guiding-bracket 14 is a reciprocating part or slide l5, having a driver 16 IOC lat its lower end for forcing thc wooden pegs into the holes punched by the awl 13.

The mechanism for splitting off and feeding the, pegs into position to be acted' upon by lille driver 416 and the gearing for impartinglth/e proper motion to the part-s of the pegdriving mechanism may'be of any o f the orv-v dinary or approved constructions,which need not be herein shown or described at length.

In that classof pegging-mac'hines to which my invention relates the ends of the pegs have. heretofore ordinarily been allowed to project through the work w and have had to be cut out by hand or, by the use of additional ma'- chinery. To overcome this defect,"Ilprovide meansfor automatically trimming or cutting off'the projecting ends of the pegs. A`s\illnstrated, the button or anvil B comprises a lower or gea'rscction 18 and a top section or cover 2l. A washer; as 20, is interposed between tliese sections, and (the. parts are secured together, as by meansof small screws, as 22.

Mounted in suitable-ways iu'the cover or plate 2l and resting uponrthe washer 20.1 provide a spring'pressed piece or guide 24, which is formed with a socket or opening 2,5 for receiving theiendsof the pegs and with a beveled or cutting edge 26 at the rerof said socket.

lThe upper rear edge of the' piece 24 `s slightly' rounded, orbeveled, as at 27, .to'cooperate with the awl 13. i

so that the cutting edge 2G and the knife 23 may c operate substantiallyas shears. A torsional spring 28 is arranged to hold ythe piece 24 in its normal position, one leg of the torsional spring being secured in the basesection of the button B and the other leg of -said spring engaging the front of the piece 24.V

In practice'l have found that a torsional ysprin g as thus arranged will control the In ovement of the piece 24 in the most efficient manner; but, if desired, a small spiral spring may be located to engage directly against the front edge'of the piece 24, or these parts may be differently arranged and connected.

.The operation of the peg-trimming mechanism is most clearly illustrated in Figs. 5to 7. 1n Fig. 5 the parts are shown in their normal position, thenwl L3 being raised clear of the work w and' the driver 16 being in position to engage with a wooden peg, as p. The slidell will vthen move'down, bringing the awl 13 in engagement 4with the work, andai;

or about the same time the driver 16 will be actuated to drive home the peg 13,'as` ,illustrated inv Fig. 6, the end of the'peg extending into the socket 25 in the piece 24. The entire head or slide l0 will then be shifted laterally to respace the work w, bringing the parts into therposition illustrated in.Fig.'7 and moving .the peg into engagement with the bl'ade or knife 23, so that the end of the peg will be sheared or out olbetween the knife 23 and the beveled edgev26. The driver 16 and the awl 13 will then be raised, and the head 10 A'plate or knife 23 is secured: in the plate,- 21 in position to cooperate with the piece2-1,A

will be shifted to bring the parts back to the position illustratedfiinsliig. 5, the piece 24 bev,

ing restored to its normal position by means of its spring 2S. ranged and mounted in thebutton B will prevent the pegs from crippling, twisting, or becoming loosened in the work when they are lbrought into engagement with the stationaryi knife or blade 23, and the shearing action of the blade 23Y and the cutting edge 2,6 willinsure an even trimming or cuttingo'f the pegs.

The piece 24 as. thus ar- K I. am aware that changes may be madein 'l the construction of peggi'ng-m achines by those who are skilled in the art without departing I from the scope of my invention as expressed Y y vinthe claims and that certain features of my invention may be used in different constrnef vtions and in diierent combinations.

I `do not wish, therefore, to be limited to the forms which I have shown and described; but

What Ido claim, and desire to secure by Letters Patent of the United States, is-.

l.A In `a pegging-machine, the combination vof a vertical spindle journaled in the frame of the machine by means of suitable ball-bearings, ahorn carried 'by said spindle, a lifting` spring coiled around said spindle, a. button jor an-vil 'jo'urnaledA in said horn, a -vtreadle-rod loosely connected to the lower end vof said spindle, a rod rigidly connected to said treadlerod, and strain Ao l' gearing for holding the button stationary independently of the rotar tion of lthe horn, substantially as described.

ICO

2. In a peggin machne, the'combination of a vertical spi dlej journaled in the frame f i of the machine, ahorn carried by said spindle, a buttonor anvil `journaled in `said horn, a treadle-rod loosely connected to the lower end of saidspindle, a rod or spindle rigidly connectd to said treadle-rod, and a train of gearanvil having a stationary blade orknfe 23, a'

movable piece 24 for receiving the projecting ends of the pegs, saidpiece 24 being provided with a spring 2S for holding the same in its normal position, substantially as described.

In testimony whereof I have hereunto set my handlin the presence of two rsubscribing witnesses. l .I
