. a specification.

My invention is especially uset'ul when applied to a warping-machine that is being-used to make chain-warps of cotton, and which are subsequently to be dyed; and it consists of the construction and combination ot parts as hereinafter set forth.

My invention is illustrated in the accompanying drawings, in Which- Figure lis an elevation of a warping-machine that is provided with my invention. Fig. 2 is an elevation, upon a larger scale than that of Fig. l, of certain of the important parts shown in Fig. l. Fig. 3 is a partial elevation, partly in section, at the line a a of Fig. 2, and seen when looking toward the left at that line. Fig. 4L is an elevation, seen when looking at the left-hand end, of some of the parts shown in Fig. l; and Fig. 5 is an end elevation of the cut-cylinder, which is sometimes used to stop the machine to which my invention is applied when a certain predeterminednumber of yards of yarn has passed therethrough.

Similar refei'encenumbers refer to similar parts in all of the views.

It is very desirable when making some kinds of warps that the warping-machine should be stopped at intervals and leases inserted, 0r in order that cut-marks may be made to indicate the place where the cloth is to be cut apart when the warp is woven. The machine should also be stopped at the proper time to allow the warp-threads to be cut oft and another warp begun, and all these operations should take place when certain predetermined lengths of yarn have passed through the machine. It is now desirable to be able Serial No. 270,342. (No model.)

desirable to stop the machine at the proper times for the purpose of inserting a lease. It is, however, frequently desirable to use a warping-machine to make what are called chain-Warps, which are to be dyed in that state, and in such a case it is often desirable to stop the machine at the end of each cut and tightly tie a string or other band around some of the yarn. The yarn will not in that case be fully dyed under the band, and when the warp is put into a loom the mark so made is readily discernible, and will serve as a guide to the weaver in cutting off the cloth at the proper places. When a certain. definite number of cut-marks have been made, it is usual, when making chain-warps, to put in a lease, and the warps are usually made to contain a certain deiinite number of such leases, and consequently a number of cuts, which is a multiple of the number of leases in the warp. It is desirable to be able to vary the number of yards of yarn in a cut, and the number of cuts between two leases, and the number ot' leases in a warp, and to stop the warping-machines at the end of each cut and warp, whatever be the length of yarn in a cut, and the invention illustrated in the drawings is intended to make it possible to fulfill all of these requirements.

In the drawings, the yarn l is represented as passing through the warping-machine and through the leasing-combs 2 to a hailing-machine, upon which it is formed into a ball, Y

I o'o lent, attached to said shaft.

the stud 6, and is firmly held in place by clamping it between the frame 11 and the collar 12, by means of the nut 13. The idlerwheel 8 engages with the cut-wheel 14. The circumference of the measuring-roll 3 and the numbers of teeth in the wheel 5 and the pinion 7 are preferably so selected that when a yard of yarn passes over the measuring-roll, thereby rotating it by frictional contact therewith, the cut-wheel 14 will be rotated through an angle equal to that occupied by one of its teeth. The cut-wheel 14 is preferably Vwhat is known as a change-wheel, a wheel which is readily removable and replaceable by a wheel having a different number of teeth, and it is shown as supported upon a sleeve 86, which is attached to the pinion 15, 4and as secured thereto by the nut 16. The pinion 15 is supported upon the stud 17, and engages with and turns the cut cylinder or cam 18. The cylinder 18 ispreferably provided with one or more pins 27, which engagewvith the teeth of the pinion 15, and which may be placed in thespace between any desired pair of consecutive teeth. This is a desirable feature, as it renders it possible to easily adjust the position of the cut-cylinder. The cut-cylinder 18 is provided with a notch 19, into which and toward the axis of said cylinder the ends of the arms 2O and 2l drop when said cylinder rotates far enough to bring said notch under said ends. One side of the notch 19 is nearly radial, in order that the arms 2O and 21 may suddenly drop when the notch reaches them, while the other side is inclined, in order that said arms may be easily raised to their normal position by the rotating cut-cylinder 18.

The arm 2O is iirmly attached to the rocking shaft 22, and its end is caused to fall into the notch 19 by the weight 23 or its equiva- This weight 23 is attached to the shaft 22 by an arm, which holds the center of gravity of the weight at a little distance from the shaft, the tendency of the weight to fall holding the end of the arm 2O iirmly against the cut cylinder 18.

The arm carrying the weight 23 is shown as provided with acam 24, attach ed either directly to said arm or to said weight. This cam, when displacedfrom its normal-.position in consequence of the end of the arm 2O dropping into notch 19,comes in contact with the finger 25 and displaces it, thereby stopping the warping-machine.

' The mechanism partially illustrated for stopping the machine and set in motion by the finger 25 is nearly like. the usual mechanism used for the purpose. It is controllable by the operator of the machine at any time, and is also put in action in the usual manner by the breaking of any thread of the warp. Any equivalent mechanism for stopyping the machine when the cut cylinder or cam has made exactly one revolution may be 'substituted for that illustrated whenever it is desirable to do so. The arm 21 is used in order that the gong 26 may be rung by the hammer 28 whenever the end of the arm 2O drops into the notch 19. The arm 21 is loosely supported upon the shaft 22, and its end is held against the cut-cylinder 18 by the spring 29. This loose arm is used in the mechanismin order that the gong 26 may be promptly struck a single blow at the moment the end of the arm 2O begins to fall into the notch 19, said arm 2O not usually falling quickly enough to properly ring said gong by a hammer attached to it. Any equivalent quickstriking hammer may be attached to the mechanism to ring the gong 26, when the end of t-he arm 2O begins to fall into the notch 19 instead of the arm 2l., whenever it is desirable to do so.

The operation of the mechanism thus far described is now readily to be understood, and is as follows: The number of yards to be put into a cut having been determined, a cut-wheel 14, having the proper number of teeth, is selected, and the idler-wheel 8 is adj usted in position in the usual way to transfer the motion of the pinion 7 to said wheel 14, and the cut-cylinder 18 is adjusted in tho position shown in Figs. 3 and 4. The machine being now set in operation will run until it is` stopped by the breaking of some thread or by the operator of the machine or until the desired number of yards of yarn for one cut has passed the measuring-roll 3. The end of the arm 20 will then drop into the notch 19 again, the cam 24 at the same time stopping the machine.4 The cut-mark may now be applied or attached to the yarn and the machine may then be again started, when it will run, if all things are in good order, until the end of the arm 2O again falls in to the` notch 19, when another cut-mark may be applied or attached. It is evident that the gong 26 is struck whenever the machine is stopped by the action of the cut-cylinder 18 and its connected parts, thereby calling the attention of the operator to the fact of the stoppage. If it be only desired to stop the machine at the end of each cut, no mechanism further than that thus far described would need to be used; but if leases are to be inserted at regular intervals I prefer to add other mechanism, now to be described. I prefer that the leases may be inserted at the same time that a cut-mark is applied or attached to the yarn, and I therefore prefer to drive from the pinion 15 the wheel 30, that is supported upon the stud 3l. The stud 31 is attached to and supported by the swinging support 32, which is secured and swings upon the 'stud 17 in a similar manner to that in which the idler-support 10 is secured and supported by the nut 13 and collar 12 on the stud 6 by means of the nut 3.7 and the collar 38.

To the wheel 30 is secured the pinion 33,

which turns with said wheel 30, and whichy engages with the lease-wheel 34. The leasewheel 34 is a change-wheel, and is supported upon a shaft 35 by the nut 36 and col- IOC IIO

IIS

lar 39 or other means in such a way that said shaft rotates with said lease-wheel. The shaft 35 passes through the frame 11 or other suitable support, and upon it is also supported the lease cylinder or worm 40.

The lease-cylinder is provided with a notch 41 running longitudinally upon it, and with another and shorter but deeper notch 42 at its end. The lease-cylinder is provided upon its surface with a worm or screw thread, and in the space between two adjacent screwthreads there works the lug 43, which is on the bell-support 44. The lug 43 is made so that its point may fall into the notches 41 and 42 when it arrives at the proper place to do so; but it is inclined at its back, so that the cylinder 40 will in revolving easily raise the bell-support 44 to its normal position, the said inclined part servingto cause the lug 43 or some part of it to always lie in the groove between two screw-threads. This coustruction of the lug 43 is shown in Fig. 3.

The bellsupport 44 is `supported by the ears 46 upon the shaft 22,longitudinally upon which it can be readily moved, and, as the lease-cylinder 40 revolves, the lug 43 drops into the notch 41 at every revolution of said cylinder, ringing the bell 45 (which is preferably supported on a thin flat spring 49) when it falls, thus indicating the proper time for the insertion of the lease and informing the operator of the stoppage of the machine. The bell 45 may sometimes be omitted.

I prefer in some cases to cause the falling of the bell-holder 44 (in consequence of the dropping of the lug 43 into the notch 41) to stop the machine, and this result is readily attained by holding up the weight 23 by said bell-holder by means of the dog 47, which is attached to the shaft 22 by a set-screw 87 or other suitable means, and which usually rests upon the longitudinal bar 48, that is connected with the bell-holder 44. The dog 47 may be adjusted upon the shaft 22 in such a way that the machine may either be stopped at the end of every cut or only atthe time that a lease is inserted. The latter method of adjustment is illustrated in Fig. 3. I usually form two iiat places in the proper positions on the shaft 22 for the end of the set-screw 87 in the dog 47 to strike, and said set-screw is adjusted to strike one or the other of these fiat places as the machine is or is not desired to stop at the end of every cut.

The machine may be made to stop at the end of every cut by adjusting the dog 47 to allow the shaft 22 to rock downward far enough to stop the machine before the dog strikes the bar 48, the weight 23 being held up in that case by the end of the arm 20, which then would rest upon the eut-cylinder 18. The pins 27 may be made to engage with any desired space in the pinion 15, thus enabling the operator to adjust the device, so that the lug 43 and the end of the arm 2O will simultaneously fall into the notches made for the purpose.

If the device is to be used simply for the insertion of leases, the spring 29 may beloosened or removed, so that the gong 26 will never ring, while if both cut marks and leases are to be inserted the spring 29 is put into place and the operator is informed by the ringing of the bell 45, with the striking of the gong 26,when to put in a lease. Theend of the warp is indicated by the lug 43 dropping into the deep notch 42, and thus more violently than usual ringing the bell 45.

The number of cuts in a lease may be easily fixed by ehoosing a lease-wheel 34 with the proper number of teeth, and I find it usually convenient to so arrange the gearing that four teeth on the lease-wheel may be equal to one cut, although any other convenient number may be chosen instead of four for this purpose. The number of leases in a warp is controlled by not using the whole of theleasecylinder, but by raising the lug 43 from between the screw-threads and moving it away from the end containing the notch 42 until it has passed as many threads of the screw on the surface of the lease-cylinder as there are desired to be leases in the warp. The shaft. 22 may be graduated and numbered, if so desired, to facilitate this operation.

The gong 26 may be omitted sometimes, and sometimes some other form of bell may be substituted therefor, if so desired.

The mechanism driven by the pinion 15 may sometimes be omitted, as well as the pinion 15 itself, if it is desirable todo so, the cutcylinder 18 being in that case directly attached to thecut-wheel 14.

I do not desire to limit myself to the exact construction of all the parts as illustrated, nor to using this yarn-measuring device only on warping-machin es.
