T0 all whom t 'may concern:

Be it known that I, GEORGE W. KUE'N- Nn'rH, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Beaming Machines, of which the following is a specilication.

This invention relates to beaming machines, and particularly to machines for beaming warps which have been laid spirally on the reel ot the machine in warping, as in spiral sections by the so-called Swiss horizontal warping method;

My invention contemplates principally the following improvements: (1) A novel arrangement and construction or" the traversing beam carriage, its supporting means and transversing means and the means to rotate the beam; a novel mounting for the beam inthe carriage; (3) the provision of a novel beam-carriage supporting means in combination with the frame of the machine, whereby an old-style frame may be adapted to receive a longer beam and thus accommodate the' more modern and wider warps; (4;) novel means for 'drivingand controlling the rotation 'of theY beam; and (5) novel means for disconnectively connecting the reel shaft with the rotary feed-screw (of the carriage traversing means) for purposes to be explained hereinafterin detail.

ln the frame a; is journaledthe reel b adapted to be driven, when warping, through the medium of a belt-and-pulley connection, generally denoted by the character c, from one Vof a pair of pulleys 17--18 (to be described) when by means or the lever CZ the pulley e ofsuch connection is shifted into contact with the driving wheel or band f o1 the reel, all in the usual manner. The usual brake-strap 7 is provided to resist rotation of the reel, the same bearing against the band f. One end of the reel shaft Z9 carries a sprocket-wheel Vg affording part of a sprocket-and-chain connection for ytransmitting traverse motion to the reed-carriage (not shown) ot' the machine, as usual, when it is being used for warping. The other end of said shaft carries the' here'inbefore-mentioned' coupler-head, to be described in detail.V There is shown in Figures 1 and 2 a certain means it tomaintain control of the warp; but this is not at all concerned with the present invention. l reserve it for another application.

The frame o: shown is the well-known old-style wood frame. Modern frames, because modern warps are prepared in greater1 width than formerly, are not adapted to receive beams capable of accommodating such warps and at the same time of having the necessary traverse ii: it is sectional warping and beaming that is to be perforn ed. )Wherefore I lit to the frame an extensionv frame constructed as follows: There are two brackets c' e" each consisting of a bodyelevation oi3 what apportion y', which is bolted to the end of the nid 7; than between the sides of the frame a) excepting that the near bracket in Figure 1 has upward and downward projections Z and m (Figures et and 5). Legs m may support these brackets. Y

ln these brackets are secured the guiderods n on which the beam-carriage traverses. On the guide rods is secured a cross-head o, arranged a suitable distance from the lrigl'ithand bracket e'.

The carriage comprises two heads pand g apertured tol receive and slide on the guide rods and connected by the tie-rods r which are preferably fixed in say the head y; and

adjustably held in the head g by the set screws s so that the two heads may be set different distances apart. On the basal or body part ot the head n is bolted, supported by the adjusting screws t, a bracket/lJ in which, by set-screws fu, are secured the boriaontal studs w, on which is in turn secured, by the set screw fr, a bracket y. rIhis construction lpermits not .only the effective height of the Yhead p to be altered in leveling-up the beam but its superstructure to be moved horizontally relatively to its basal part, for a purpose to be explained. The other head g forms a narrow upright housing, the top part of. which may form a removable cover g', and in itis journaled a tubular shaft e having keyed on it a gear wheel 2 and protruding at the inside and having suitably Secured thereto the arm 3 vto which is attached the beam-lashing 4l.)

rllhe beam 5 has its trunnions set in a bear-v ing in the bracket y and in the tubular shatt e, being adapted to be secured to arm 3 .by vthe lashing 4. Y.

ln the bracket t' andthe cross-head 0 is j ournaled the drive-shaft 6 carrying a bearing head 7, which is keyed to the shaft and holds it against left-hand movement. In the bracket z" and said cross-head Vis journaled the feed-screw 9., held against longitudinal movement by 4a collar 10 'and a sprocket wheel 11; this sprocket-wheel preierablyV has a handle 12.

The drive-shaft 6 carries, Splined thereon and confined in the housing of head g/ between its two side walls, a pinion 14e in mesh with the'gear wheel 2. Engaged with and penetrated by the 'feed-screw 9 is a nut 15 vwhich is conned between opposite walls ,of4 the basal part of head 7; and held against turning by the pin 16.

On the bearing-head7 are journaled, integral with each other, the hereinbe'lorementioned stepped pulley, 17, and the main drive pulley 18. In slots therein the bearing-head has keys or wedges 7, whereby to establish a frictional interlock or clutch between the bearingshead and pulley structure upon pushing inwardly against said keys a thrust-piece 19 suitably tapered at its inner end to cam the keys outward Vr-gainst the bore of said pulley structure.

rl`h1s wedge-piece is normally retracted by.l

a spiral spring 2O interposed between the bearing-head and a shoulder on the wedgepie'ce. lts inward movement is adapted to be effected by a lever 21, journaled in an overhanging arm 21 bolted to the projection Z of bracket e' with which the wedgepiece has a swivel connection as shown in Figure 9, when the lever is actuated from a treadle 22 'extending across the machine through the medium of a'chainl 23 connect-- ing the treadle with a sprocket-wheel 24 journaled in a bracket 25 bolted to the projection fm of bracket t', and a chain 26 connecting-'said sprocket-wheel and lever.

On the drive-shaft 6 is securedva ratchetwheel 27. A pawl 28 coacts with this ratchet-V wheel to prevent backward rotation of the beam when, on releasing treadle 22, the

power is cut 0E from the drive-shaft 6, leaving the tension of the warp (since the reel is held by brake-strap f)v otherwise free to cause reversal of the beam. ln previous beaming machines ysuch .pawl clicks 'idly over the teeth of the ratchet-wheel when the latter is rotating, but in my construction-it vis held clear of the ratchet-wheel at that time and only engages therewith when,V the power v is cut off and the beamvisxto stop, thus to avoid undesirable noise.v The pawl, 28, is fulcrumed on one of the guide-.rods yand a spring 29 tends to hold itV against thevratchetwheel. But a flexible connection 30 'extending over a suitable sheave 31 and vconnected to the sprocket-wheel 24 is caused, whenever treadle 22is depressed,toestablish the power, i

to retract the pawl. In consequence the ypawl is always clear of the ratchet-wheel while 1 i the Vlatter is in motion, though it same as soon as it stops. y v

The hereinbstore-mentionedv coupler-head comprises a vsleeve 32 pinned to the reel shaft b and supporting, in axial alinement with the reel shaft, a bearing stud 32', which protrudes from the sleeve. Pinned on the bearing stud is a crosshead 33 equipped on one arm with a pivoted spring-pressed pawl 34 and on the other with a radially adjustable toothed dog 35, 35 being abolt to clamp the dog in any position to which itis adjusted and being received in a radial slot 35f in the cross head; said coupler-head further comprises, revoluble on the stud 32', a combined sprocket-wheel 36 and ratchet 37, the latter being engaged by the pawl 34 but not (normally) by dog 35, which usually stands retracted-not as shown in Figures 11 and 12. A sprocket-chain 38 extends. around the sprocket-wheel 36 and sprocket-.wheel 11. In a hole 39 in the cross-head a pin or equivalent detent may be introduced to hold the pawl clear of the ratchet at certain times. l

Operation: lt will be understood thatin order to rotate the beam in beaming it is only engages the necessary to hold the treadle depressed to establish the clutch between the suitably driven pulley structure 17-18 and the bearing head 7 g this, as explained, disengages the pawl 28 from ratchet 27, which is held disengaged so long as the treadle remains depressed, but returns into engagement when pressure on the treadle ceases. While the beam and consequently the reel are thus rotated in beaming pawl 35 turns the ratchet and sprocket-wheel 37-36 and through chain 38 and sprocket-wheel 1l drivesthe feed-screw, so that the carriage traverses to the right. At the startthe carriage is always set to abut the left-hand bracket z". The sections spirally laid on the reel, successively, in the warping operation are now all at once removed and beamed. When the beaming is completed the operator shifts bracket y clear of the filled beam and replaces it with an empty one, whereupon by manually turning backward the sprocketwheel ll theJ feed-screw is made to reset the carriage to its starting point for another traverse; to avoid the noise of the clicking of the pawl over the teeth of ratchet 37 at this time he may lock back the pawl by means of pin 39. Occasionally it becomes necessary while a warp is in process of being beamed to wind it back onto the reel from the beam. This is done by turning the reel backward by hand (the clutch between the pulley 17 and shaft 6 being then disestablished), and in order that there may be a corresponding reverse traverse of the beam carriage the dog 35 is shifted into kengagement with ratchet 37 and secured by its bolt 35, so that by bearing against the inclined face ofone of the teeth of the ratchet it turns the latter and so through the chain 38 rotates the screw 9 backward.

I obtain a more direct drive and greater simplification of structure by splining a part (as 14) of the gear train on the main shaft 6, and by journalling this shaft and the feedscrew on the one hand in the respective side portions (brackets i) of the frame and on the other in the common support afforded by the cross-head o, which connects and braces the rods a forming the guideway for the carriage.

Heretofore when the beam was unshipped it was necessary to shift one entire end portion of the carriage away from the other in order to clear the beam trunnion; by my invention the head ,o remains fixed and only its bracket jz/ is shifted.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. In combination, a frame including spaced members, a pair of horizontal guiderods connecting them and a cross-head connecting said guide-rods and arranged between and spaced from said members, a

beam-carriage shiftablealong the guide-rods and having supporting portions resting `thereon one on each side of the cross-head, a drive shaft journaled in one of said members and the cross-head, and a transmission train connecting the beam with said shaft and having one member thereof splined on the shaft and confined to the carriage to shift therewith.

2.1n combination, a frame including therein, a pair of spaced horizontal guiderods connecting said members, and a crosshead connecting said guide-rods, and arranged between and spaced from said members, a beam-carriage arranged on and shiftable along the guide-rods, a beam ournaled in the carriage, a drive shaft journaled in one of said members and the cross-head, a feed-screw journaled in the other member and cross-head and having a threaded connection with the carriage, means to transmit rotary motion from said shaft to the beam, and meansv to transmit rotary motion from the reel to the feed-screw on rotation of the reel from the rotating beam through the warp being beamed.

4.
