Specification of Letters .Patent.

P tented May 1 1909.

Application filed June 5, 1908. Serial No. 436,851.

To all whom it may concern;

Be it known that LNIor-Ioras A. Hovnn, a citizen of theUnited States, residing in Paterson,'l as'saic county, New Jersey, have invented certain new and useful improvements Warping and Beaming lvia chines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of ref- 'erence marked thereon, which form a part of this specification.

My invention relates to warping and beaming machines, and it has reference particularly to warping and beaming machines of the kind whereinsections of the warp are successively laid side by side on the reel, in the warping operation, and, in the beaming operation, are taken from the reel onto a beam all in one operation.

' My present inventioninvolves certain improvements on a warping machine described and claimed in an application for US. Letters Patent bearing the Serial No; 401,200. In that application's warping mechanism is disclosed which comprises as its essential feature a carriage adapted to be moved by hand transversely with reference tothe reel to a new position each time the laying on of one section of warp has been completed and the laying on of a fresh section of warp is to begin, another carriage arranged to slide travefSQly of the reel in the first-named carriage for the purpose of imparting a traverse to each section of warp as it is laid on the reel, and means for moving the second carriage on the first. Oneof the novel features of my improved warping mechanism as presented in the present application is a means whereby the manual movements of the first carriage may be gaged with precision, so that the spacings between the several sections of warp laid on the reel will be-accurate and substantially identical; others involve the adjustability of various parts to meet varying conditions and the rendering of the mechanism generally more reliable in operation, convenient to handle and substantial in construction.

My improved beaming mechanism involves a novel means for effecting the proper rse of the beam. 2

In devising both the warping and beaming larly so to construct the same that they may be applied to any warping machine ofthe type above indicated at present in use with the minimum loss of time and labor.

Referring to the accompanying drawings, Figure 1 is a side view of a Swiss warping and beaming machine embodying my improvements; Figs. 2 to 8 show the warping mechanism in detail, 2 being a plan view, certainparts appearing in section and others broken away; Fig. 3 a sectional view on the line 03-a of Fig. 2; 4 a somewhat smaller view on the line y of Fig. 2 Fig. 5 an enlarged detail View of the reed supporting means; Fig. 6 a view illustrating a modifica tion of the means for eifecting the traverse of the second carriage; Fig. 7 is aside view and Fig. 8 a sectional View, line z2 of 7, of another modified form of traverse mechanism for the second carriage; Figs. 9, 10,11 and 12 show the beamingmechanism, Fig. 9 being a front View; Fig. 10 a plan; Fig. 11 an end view; and,Fig. 12 illustrates a detail.

In the drawings a designates the frame and b the reel of a Swiss warping and beam ing machine; from the reel shaft 0 power is adapted to be transmitted to the warping and beaming mechanisms as hereinafter described by means of the sprocket chains Z and c. The frame a comprises the usual par; allel side rails Referring, first, to the warping mechanism, 9 designates two plates each having the out ward overhangs hand said plates being connected by the guide rods 2, the plates and rods being secured together by the set screws j (Fig. 1). The framework thus formed is adapted to be supported on the frame a by the'overhangs h resting on the rails f, the plates g being held against the inside faces of rails f by the bolts 7r, it will be understood that the framework comprising the plates and rods may be adapted to fit varying widths of frames a by simply altering the length of therods i. i What I have heretofore designated the first carriage will be hereinafter designated the main carriage; the second carriage, I shall designate the auxiliary carriage.

The main carriage Z comprises the side bars at and the integral connecting bars it. Through the rear end of each side bar m extends the rear guide-rod i, the forward end of each side bar being arched over and resting inechanisinsj haye had in mind particu upon thefront guiderod i, as at o. Heron fore the carriage has been penetrated both front and rear by the guide rods, so that if the front guide rod became buckled through undue strain thereon, as by the operator leaning against it, the carriage would not move freely. My present arrangement permits the carriage to move freely although the front guide rod becomes bent, and allows the carriage to be raised on the rear guide rod as a fulcrum for the purpose of access to any of the parts for repairs, etc. The main carriage is adapted to be secured against lateral movement while a section of warp is being laid on the reel by the clamp p which bears at one end against the under side of the front guide rod i and at the other end against a toe on the end of one of the side bars, said toe being received by a notch 1" in the clamp, and between its ends the clamp is penetrated by a handscrew 8 arranged in the side bar m. A splined shaft tis journaled in the plates 9 and extends at one end through the rail f, having thereon the sprocket wheel a over which extends the chain (1 and which cooperates with a collar 1) to prevent lengthwise movement of the shaft. The shaft 15 penetrates the sidebars m of the carriage Z and its spline to extends approximately from one plate 9 to the other, the shaft receiving a screw-sleeve as which is arranged between and abuts at its ends against the side-bars m of the carriage Z. This screw-sleeve may carry one or more keys y engaging the spline w. The arrangement just described allows the main carriage to be shifted laterally by hand, the screw-sleeve moving with it on rotating the shaft the screw-sleeve, bein splined thereto, rotates therewith. As wi 1 be indicated later, the

' screw-sleeve operates automatically to effect the traverse of the auxiliary carriage as a warp section is being laid on the reel.

In order that, as often as it becomes necessary to start to lay on a fresh warp section, the spacings between the several warp sections may be maintained uniform, 1 provide the gage shown in Fig. 2, the same consisting of a short rod 2 which slides freely in one of the side-bars m and has a stop-pin 1 in one end, its other end penetrating a collar 2 which is adapted to be fixed to the rear guiderod 1', on which it is arranged, by the setscrew 3; the rod 2 is adjustably secured in the collar 2 by the set-screw 4. Assuming that the spacings are each to be a given number of inches or fraction of an inch, the rod 2 is moved lengthwise until the stop-pin abuts against the inside of the side-bar m, Whereupon the collar 2, by manipulating the setscrew 4, is set so that the distance between the side-bar and the collar will correspond with the desired spacing between warp sections. The manner of utilizing this gage will be explained later.

The side-bars m are connected by the parallel guide-rods 5 secured therein by the setscrews 6. On these guide-rodsis adapted to move the auxiliary carriage 7, its downwardly projecting lugs 8 being penetrated by the guide-rods 5. When the screw-sleeve a is rotating the traverse of the auxiliary car 1 riage is effected therefrom through the wormwheel 9 which is arranged on the stub-shaft 10 secured on a downward portion 11 of the carriage 7 by a set-screw 12, the free end .of the stub-shaft 10 being threaded and receiving a nut 13 adapted to bind the worm-wheel in fixed relation to the carriage; upon releasing the nut, the carriage 7 may be moved laterally by hand, the worm-wheel then rotating idly. The rear end of the carriage 7 has a longitudinal groove 14 receiving the feather 15 of a bracket 16 in the upper end of which is j ournaled a roller 17, the bracket being secured to the carriage 7 by a bolt 18 penetrating a slot 19 in the carriage. The roller 17 may thus be adjusted to and from the reel, as the conditlons require. The warp extends over the roller 17 but under another roller 20 which is ournaled in a forked bracket 21 secured to the carriage 7 by the bolt 22, one bearing for the roller 20 in bracket 21 opening downwardly and the trunnion of the roller being adapted to be removably held. therein by a weighted pawl 23. The carriage has a forwardly extending arm. 24, on which, by means of a belt 25 forming a vertical swivel, is arranged the stand 26; on the horizontal screw 27 arranged. in this stand is ivotally mounted the two-part clamp 28 or the reed 29. This reed may be adjusted, to widen or contract the warp sections, on the bolt 25 as a pivot, as indicated by the arrows in Fig. 2, or it may be adjusted on the screw 27 as a pivot, as indicated by the dot-and-dash lines in Fig. 3, to change the position of the reed according to the angle of approach of the warp sections. 30 is a fixed. reed arranged on the end of arm 24.

In lieu of the disconnective traverse means between the carriage 7 and the screw sleeve already described, I may employ that shown in Fig. 6, where 31 designates reverse bevel pinions fixed on a shaft 32 which rotates freely in a downward projection 33 of the carriage or which may be held against rotation by the binding screw 34 having the handle 35. Or 1 may employ the disconnective traverse means shown in Figs. 7 and 8. Here the carriage 7 has the depending lugs 36 in which is journaled the short rock-shaft 37 on which is pinned the segmental nut 38, one end of said rock-shaft carrying a handle 39 which is pinned thereto. When the handle is turned, the nut is thrown into or out of engagement with the worm -sleeve It will be observed that the nut 38 is slightly narrower than the space between the lugs 36; this is to allow the nut to have movement lengthwise of the worm-sleeve in order that the teeth of the nut may find the spaces between the threads of the worm sleeve. In order to hold the nut against rotation when engaged with the worm-sleeve and also prevent its movement at suchtime longitudinally of the worm-sleeve, Iprovidethe clamping pm which has some slight longitudinal movement' in one of the lugs 36 and is formed with a recess 41 receiving the rock-shaft 37, its free end being threaded and carrying a nut 42; Onscrewing nut 42 tight against the lug 36,. the in 40 binds against the rockshaft and ho ds it against movement.

Referring, now, to the beaming mechanism, 43 designates plates bolted to the siderails f and having overhangs 44 resting thereon, said plates'being connected by the parallel guide-rods 45., In one of the plates 43 anda brace 46 connecting the guide-rods is journaled a screw 47 on which is fixedthe sprocketwheel 48-, around which extends the chain c. 49 and 50 are brackets arranged to slide on the guide-rods 45, the bracket 49 forming a journal for the shaft 51 which. carries the chaii'i-clutch 52 and the gear-wheel 53 which is'splinedthereto and isdriven by a pinion 54 carrying a pulley 55 around which and another ulley 56 driven by the reel b extends a be t 57 the shaft 51 has additional support in the bracket 58 carried by one ofthe side-railsf. The bracket 50 is formed with a stepped portion 59 in the lower part of which is an opening 60 above a nut 61' having the toothed portion 62 and arranged on the screw 47. In the bracket 50 is pivoted a detent 63'whieh may be engaged with the teeth of the-nut to hold the same against rotation and whose free end may carry a pin 6'4. The bracket 50'also carries an open bearing- 65 for the beam 66 which is supported at its other end in the chain clutch 52.

The operation of my improved warping and beaming mechanism is as follows: In warping the wells rotated from 55 through 571 and 56, a friction wheel 67 on the pulley 56 being at this time held in engagement with the reel in the usual manner. As the reel draws the warp and winds it the auXiliary carria e moves to the right in the main carriage. reviously to starting the warping operation, the main carriage is moved to the right as far as it will go and the auxiliary carriage to the left as far as it will go in the main carriage. The auxiliary carriage will be fedto the right by the worm-sleeve as, and when a predetermined, length of the'pa-rticular warp section then being laid on the reel hasruir out, the carriages are reset. The gage for then-lain carriage is moved to the left until the pin ,l abuts against the left hand side bar of said carriage and there clamped by means of hand screws, whereupon said carriage is moved against the collar 2; this determines the spacing which is required betweenthe warp section already laid on and the warp section about to be laid on the reel. Then the disconnective con necting means between the auxiliary car riage and the worm sleeve is released and the auxiliary carriage again set as far as it will go to the left in the main carriage. The reel is now started up againand the second warp section laid thereon. This operation continues until the reel is full. In beaming, the power is transmitted through pinion 54 andv gear wheel 53 to shaft 51 whereby to rotate the beam; the pull of the warp in this instance rotates the reel, which through the sprocket chain (2 and sprocket wheel 48 rotates the screw 47, the nut 61 being held against rotation in bracket 50 by the detent 63, which causes the bracket 50 to feed to the right, so that as the beam rotates and draws the warp off thereel the beam moves to the right to accommodate itself to the spiral winding of the warp sections which has been effected in the warping operation.

It sometimes becomes necessary to stop the warping operation for one kind of warp for the purpose of placing another kind of warp on the reel; in that case, so much of the warp as is already on the reel may be beamed. and the beam laid aside. Then, as soon as the machine is available again for completing the warping operation partly finished, the beam is replaced in the machine so that the warp thereon may be reestablished on the reel. In this instance, the reel rotates in the same direction as for warping and as it is necessary for the beam now to traverse to the left, it rotates the screw 46 in a direction opposite to that in which it rotates for beaming (the gear 5 and pinion 54 being now disconnected); as the nut 61 now tends-to move to the left independently of the bracket 50, in order to prevent it from clearing the detent 63, the pin 64 is provided to keep the detent interlocked with the nut.

My means for adjusting the screw or screw-sleeve :1 laterally with respect to the reel and also determining the new starting point for the carriage 7 each time a new warp-section is to be laid on the reel comprises, as its essential elements, two members, one being the main carriage or its equivalent, acting to confine said screw against lateral movement therein, and-the other having limited lateral movement in the first, herein being illustrated in the preferred form by the parts 0, 1, 2 and 3.
