IMPROVEMENT IN WINDINGWMACHINES.

Specification forming part of Letters Patent No. 123,251, dated January 30, 187:2.

To all whom t may concern:

Be it known that we, FREDERICK C. Eir- RENBERG and THEoDoR EHRENBERG, of the city, county, and State of New York, have invented a new and Improved Thread-Winding Machine; and we do hereby declare the following` to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference beinghad to the accompanying drawing forniing part of this specification, in which drawing- Figure l represents a side view of this invention. Fig. 2 is a longitudinal vert-ical section of the same. Fifi'. 3 is a plan or top view of the saine.

Similar letters indicate corresponding parts.

This invention relates to certain improvements in winding-machines of that class which we have described in our patent No. 76,724, datedApril14,18bS; theprincipal object of our improvements being to adapt our machine to the opera tion of windingthread or yarn on bob.- bins in the form of cops. This present invention consists in the arrangement ofthe V- shaped cop-gauge, the sliding carriage which carries it, the hinged bobbin-frame, the tappetrod, the yarn-guide, and the devices for operating the two last-named parts and the stoplever or belt-shifter, as hereinafter described, so that, as the bobbin fills up the cop, the gauge and carriage recede, whereby the desired shape of the cop is insured, so that, when the cop isnished, theniachi ne is stopped automatically, to allow the removal of the finished copand the readjustment ofthe machine for the next one; further, in the arrangement, on the carriage containing the yielding copgauge, of a hinged oscillating thread-guide, a cam which actuates the thread-guide, and a worm-wheel, which actuates the cam, and which receives motion from a screw-thread on the main shaft, in such. a manner that the thread-guide retains its proper relative position to the cop-gauge throughout the whole operation, and that the thread is laid on evenly from one end of the cop to the other.

In the drawing, the letter A designates a bed-plate provided witha bracket, B, by means of which the machine is secured to a bench or other suitable support. From the bed-plate A rise two standards, C C', which form the bearings for the driving or main shaft D. To one ot' these standards, C', is connected, by a hinge-joint, a., a yoke or frame, E, which forms the bearings for an arbor, b, which is intended to receive the spool. On said arbor is mounted a pinion, c, which, when the spool-frame is turned down to its working position, meshes into a cog-wheel, d, mounted on the main shaft D, and a weight, e, which is secured to the a-rbor b or to the spool-frame, serves to keep the pinion in gear with the cogwheel. To said arbor is secured acollar, j', from which proiects a pin, g, that catches in a hole in the end of the bobbin, (see Fig. 2,) so that the bobbin, when placed on the arbor, is compelled to rotate with the same. The spool-frame is hinged, so that it can be turned up to a vertical position, for the purpose of facilitating the introduction and the removal of the bobbins. rlhe main shaft D forms the guide for a carriage, F, the bottom end of which travels in grooved ways G, formed in a projection of the bedplate A. From the top of this carriage eX- tends the V-shaped cop-gauge H, and from the bottom part ofthe carriage projects an arno, I, which forms the bearing for the pivot h ofthe lever J, which carries the threadguide 'z'. The lever J is made in the form of a bell-cran k, and to its horizontal arm is secured a weight, j, which serves to keep a roller, 7a, mounted on the vertical arm of said lever, in contact with a ca-m, K, that serves to impart to the thread-guide the required reciprocating motion to lay the thread evenly upon the bobbin. rlhe cam K is mounted loosely on a pin, Z, which is secured in an arm, L, projecting from the carriage F, and on the hub ot' said cam is iirmly secured a wormwhecl, m, which gears in a screw-thread, n, cut on a portion of the main shaft D. As the main `shaft revolves, a slow revolving motion is imparted to the cam K, and by the action of this cam the required reciprocating motion is given to the threadguide. The carri-a ge F is pressed inward overthe bobbin by the action of a spring, M, which may be coiled round the end ot' the main shaft, as shown in the drawing, or which may be applied in any other desirable manner. As the bobbin fills up, the thread acts against the arnnr @raton V-shaped cop-guide, and the carriage F is gradually forced back in the direction ot' the arrow marked on it in Fig. l. To the outer end of the pin Z, Which forms the bearing for the cam K and Worm-Wheel m, is firmly secured a collar, 0, from which projects a pin, p, and, as the carriage is forced back in the direction of the arrow marked on it in Fig. 1, said pin catches under the inclined edge of a tappet, N, which is secured on a rod, P, that is hinged to the shipper or stop-lever Q. In the draw ing We have shown alever, Q, Whichis hinged to the bed-plate, and which is provided with a projection to catch in an annular groove, q, formed on the outer end of the (,lrying-pulley R. This driving-lmlley slides on the main shaft, and its inner end is made in the i'orm oi' a clutch, to engage With a pin, lr, secured in the main shat't, Whenever the lever Q is broughtin the position shown in Fig. l. rlhis lever is subjected to the action of a spring, S, which has a tendency to throw the same back in the direction of the arrow marked on it in Fig. l; and it' the lever is permitted to follow the action ot' this spring the pulley R is carried out of gear with the clutch-pin r and the motion of the shaft D stops. The tappet-rod P is provided with a notch, s, (see Fig. 1,) which can be thrown in gear with a pin, t, secured to an arm pr jecting from the standard C', and by these meansthestop-leverQ is retained against the action of its spring, and the pulley R is kept in gear with the clutch-pin r. But, as the carriage F is forced back by the action ot' the thread which lls the bobbin, the pin p, by its action on the tappet N, gradually raises the rod P, and, by the time the bobbin is full, the notch of the tappet-rod Vis lifted out of gear With the pin t, the stop-lever flies back, and the motion of the machine stops.

It is obvious that the stop-lever Q might be made in the form of a belt-shipper Without changing the result. By this arrangement We are enabled to till bobbins in the form of cops, and the Whole operation can be eiected in a simple and easy manner, requiring no practiced or experienced labor.

What we claim as new, and desire to secure by Letters Patent, is-

l. The combination of the sliding carriage F, V-shaped cop-gauge H, hinged frame E, yarn-guidej, cam k, collar o, pin p, tappet-rod P, and stoplever or belt-shifter Q, all arranged and operating substantially as and for the purpose set fort-h.

2. The arrangement, on the carriage containing the yielding cop-gauge, of a hinged oseillatin g thread-guide, a cam K, and a worm- Wheel, m, engaging with a screw-thread on the main shat't, substantially in the manner herein described, so as to keep the thread-guide always in the proper relation to the cop-gan ge.
