The framework of the machine should lieve considerable strength end rigidity, and may conveniently be made up of suitably .shaped and assembled lengths of ongle iron.

Thus, as illustrated inthe drawings, there :we three airs of standards, o, Zi and c, the .two erols of each aii being tied together, 'transversely' of t .e machine, by unge iron cross braces d, end the sets eist-underds being tied together longitudinally of the machine by the upper l irons e which Aoverlie the tops of the standards and `forni the upperfsuriace of the framework, and by the (intermediate l irons f which uctas braces.

The bundle table is formed of two heavy castings f] :and g, extending trnsyerselyof the machine and bolted to the upper flanges of the T irons e. `lietween these castings, :it the upper/edges thereof, extend a Series of rollers h, are shown in the drawing, though moi'e' or less `moy be employed.

These rollers constitute the bundling *trible endJ by i'eeson ol" the foctthat they me ro; tutehly mounted, ite-becomes eesyto iz'oll a bundle into position beneeth vthe twister.

- in position on \\t y mounting and node of operation of the For the purpose of securely clamping the bundle in position on the table during the twisting operation, the head-plate z' which carries the twisterand which is so mounted that it may be reciprocated vertically, also carries forwardly projecting resser arms to press down upon the bund e when it is e table. The manner of head-plate will e ,understood from Figs. l, 2, 3 and 5. The plate z' is adjustably mounted in l'a frame -1",'"which is capable of moving verticali in guide ways 1n a casting y,

which may e made integral with, or sup .ported on,` the cross bar d which joins the standardsb, b. The frame z" has a depend- 'ing tongue'z'z, by which it is reo'iprocated vertically throughv the foot levers and mechanism illustrated Ain Figs.,1,i2, '9 and 10. From these figures itwill be seen that there is a shaft c journaled in bearings in cross and b, b. Rigidly fastened to this shaft,-

bars 7: extending' between the standards a, a

at the forward end, are two foot levers or treadles Z and Z, and. rigidly fastened to the shaft at its rear end 1s a leverarm m having a slot which receives a pivotrpinlm of the toggle mechanism comprlsing the two arms n' and 1i/,pcf which the arma is fastened at its upper end to the stationary casting j and the arm a is fastened at its lower end to the lower extremity of tongue i2. From an examination of these figures it will be seen that when the short treadle Z is pressed down the toggle is lthrown to the right7 as viewed in Figs. 3 and 9, or to the left as vlewed in Fig. @,and the frame z", carrying with it the headfplate z' and the twister, is

'elevated by the springs 0 which are fastenedat their lower ends to the frame i and`at Y' are the presserarms Z3, which come down upon the bundle to clamp y1t 1n place, as

illustrated in Fig. l. The range of movement of these parts is such as to permit the.

ready placing of a bundle of predetermined size beneath the presser arms Z3, when thev head-plate is in its elevated positiom'but to clamp the bundle firmly on the table when the head-plate is depressed. By virtue of the toggle arrangement the parts stay in thev osition to which they have been broug it, 'without necessitating that the operator should keep his foot onthe treadle, or otherwise lock it in fdepressed position.

lf the size of the bundle to be tied is nialterially. changed it is necessary to adjust the positlon of the slide z' in the frame i..

For this purpose there are provided journal bearings p, with lock pins p', extending from the frame t", and in these bearings'is journaleda shaft g having outside of the framework of the machine' a hand-wheel ql',

and carrying a pinion '1' which meshes with a rack r on the slide vz'. When the slide z' is to be adjusted Ain. the frame z" the lookin pins p a'reloosened and the hand-wheel g turned so that by the turning of the pinion 1 'in engagement with the rack 'r' proper adjustment is made. The locking pins o 'are then re-set to'lock the parts inthe adjusted position.

The adjustable head-plate carrying the twister and .presser arms, as`above described, is not claimed to be broadly `iew at the present date, but on the contrary, is an im- ,provement upon the mechanism for the same purpose lllustrated and described in the .UnitedI States Letters Patent above referred to. The mostimport-ant advantage of the present construction, as compared with` the construction of -that patent so far as the operation of reciprocating the head-plate is concerned, and the feature of novelty in respect thereto which is now particularly claimed, resides in the toggle arrangement of the arms n n and the treadles Z Zl arranged to operate, thesame, whereby the head-plate may he easily elevated or d epressed by an operator at the frontof the machine, in a position to handily' place bundles on the bundling table, and whereby 'the parts remain in the positionto which they are thrown, that is,either in vthe ele` fated lor in the depressed position, as the case may be, so that the opcrators attention may not be taken up during thejbund'ling operation, with the'actuation of the clamping mechanism. r

For the purpose of twisting together the two ends of -the Wire loop' after it has been les placed about the bundle, and for cutting the l two ends Ito complete the tie, there is employed in the present machine, a twister substantially like that ofthe United States patent a ove referred to. Thistwister is fully.'illustratedin Figs. 3, 11, l2 13,

of the drawing. From these figures it will be seen that at the center of the u peren-A trex'nity of the head-plate z' the hea -plate is cut away to'form rounded lips s which yare continuedv into register with a straight slot s in a wire. gripping plate s attached tothe face ofthe rotatable twister head s. This twister headlis journaled at-its forward end in the body lof the head-plate z', and atits rearend has an extended hub -jornaled in a supporting plate t bolted to the head-plate z', as shown in Fig. 12. The twister -head;has a central bore u 'of considerably greater diameter-than the wire, and a radlal-slot 'a' theifactthat in thenor'm-al operation of the machine itis necessary, for each bond In the present machine this ii'nportant feaortie, to draw '.oii' in the first instance a greater quantityT of wire than is actually einf ployed in making thebond or ltie-after the wire has been tightened aboutthe bundle.

ture is fully-.provided 'for in a manner which will -now'be described. l

By referring .to Figs. l ,and 8 of the drawing itwill be v*seen that on the upright post which supports the wire reel, there is a re- 1- tainingcollar G on which rests the hub of a ratchet disk G', which is free to turn u on the post.. .The upper face of this rato et disk Gr is provided with a friction diskV of I rubber, leather, or the like, as seen'in Fig.

8, 'and u o n this rests a secohd friction disk on tie lower end of' a spring drum I. Surrounding the uppcrend of the supporting post is another collar H and between this andthe upper endof the hub of spring ...drum I is .a coiled. spring, which tends to `foice together the faces of the friction disks between the drum I and thei-atchet disk l. The base plate A has a centraldepending hub Gr2 which surrounds the hub "of spring drum I and turns freely thereon, 'the base plate being held inplace by the collar I'IZ. Connection between the hub G2 and theispring drum I is made' through a coiled .band spring I. 'Extending from the pe- ,ingV leosely on the hub of the ratchet disk i (sec Fig. 7) and supported on collar J', .is a lever arm .I which is connected by `link-I1=to-lever Dfi The arm J carries a pawl l( pressed by spring K into enga ement with the teeth of the ratchet disk The: object of this connection is to turn the wire reelto wind 'up theA wire' as it is drawn back by the manipulation of han-- die D.

'It is of great importance that the loop'of. wire which is to .bind the bundle should be held exactly nt right angles to the axis of thebundle during the bundling operation and for this purpose the rollers z, ofthe rollertable are arranged in the supporting castings und4 g in such a manner that the midd e rollers have an open slot or space between them, :inflat one or both ends of- 'this slot, exactly inline with the axis-of the twister (see Fig. 4) is a spring clipM,`

which grips' the loopand ho'lrls it in'fthe proper position. lhese clips have alsothe additional advantage that they hold vthe loop` open vout of the way of the advancing bundle and enable the operator, by pulling the wire with a jerk out of the clips, to draw it more tightly about the bundle than would otherwise bel possible.

of the machine in practice. In the draw -ings one has been-shown at each end of the slot in the table, but the one at the end of the slot riext the head-plate vis the more important and theother may be omitted with- Q `out`mater1ally reducing the advantages attained. The small grooved roller e* best seen in 11, serves as a 'further guide for the bindin wire and 'as a convenient anvil for there amping dog as.' i

The operation of the machine in tying bundles is as follows: The hand wheel 'o' having been-brought to such position that' the radial slot s in the twister registers with .the lips s, as illustrated in Fig.` .13,a 35

loop of the binding wire is formed by gras ing the end of the .wire just in front of t e I forward guide B2, and drawing from the;

, reel enough wire to-iorin a large o 'en loop.

The end of the wire is then laid-in t 1e slot s', 9o with its extremity bent laterally at the end of the cylindrica chamber' u, as illustrated 1n F1 11. The loop is then pressed down over t e guide roller s* and betweenlthe jaws of the spring clamp M 'which' is next to the 95 head-plate. In this way that side of .the loop is kept out of the path of the oncoming bundle.- The other side of the loop may also be forced into the sprin clamp M at the front of the bundling tab e, if such a-clamp is .provided, ther'eb further insuring the proper position of t 1e loop and its freedom from interference with the bundle. bundle is then run on to the table through the loop, is pressed back against the face of the head-plate as shown in Fig. 1, and the treadle Zl 1s thrown' down to depress the head-plate and bring the presser arms Z3 into clamping engagement with the top of the y. bundle. The operator then grnsps the front 11o side of the Awire loop and )ulls it, with a short jerk, tightly about thev back oi' the bundle, and at the sume timeinanipulates .the lever D severalI times 'to pull the wire back and draw it tightly: over the top of the 11.;

bundle.4` This operation is usually completed by a series of short,A4 quickinovements of the lever D .resulting in jerks on the binding wire, tol draw out ali the kinks and'bends.

While the wire is still gripped by cam C', 12o

and with the operator still pushing 4back ou.

the vlever D thcclam )infr-do in 1s thrown down' to press the upper strand of the wire down to the twisting position.- This further -tightens'the wire as will be readily lmder- 125 stood. The hand wheeleiis tHe'n .sharply rotated to twist the two ends of the loop und cut the wire oli'. .At each backward movement of the lever l) the link L imparts a backward throw to the arm J und through These clips add very greatly to the successful operation 70 The y Losnese the pawl K, turns the ratchet disk G. The friction bet-Ween the friction disks, due to the spring between the eollers H :ind H2, and to the Weight of the Wire and Wire reel 5. is so great thet this movement of the ratchet dislVG carries wit-l1 1t. the spring-drum l and ythe wire reel to Wind np the Wire. it will be observed that the tendency1 of the spring i is to turn the wire reel in such e 'mi direction 11s-to Wind up the Wire, but this turning is stopped by the engzigenient ot the forward pin I2 with the projection it, since when the parts here come into that position p the spring is so fer unwonnd that it will not mi lceri-y the drum il around, because oil-the fric- -jtion betweenthe friction disks.. lWhen the Wire ispnlled `od of the reel the first pant ci the movement turns the reel, Winding up the spring ,":ind this Winding of the siring E@ continues until the ree-r pin l2 engages the projection 4 and after that the reel and the .spring drum ii turn together, :the friction oi the friction disks being overcome .and the ratchet disks G being held in fined position by the pawl K. The result et' 'this construction is that there is always e tendency, due to the spring il', for the reel to wind the Wire up, and the unwinding is always against this spring tension :it first., and atter- 3@ Ward against the friction of the friction disks. In this Way crei-running of the reel is prevented and 'there is always e slight baclm'ard pull on the Wire. The degree ot this backward pull, due to spring I may be hole in which it is shown in the drawings and inserting it in another one oi' the series of holes disposed about :t circle in the base- -plete A. Four suela holes ere shown in 4@ Fig. el.
