be fully described in the subjoined specification and particularly pointed out 1n the following claims, 4

F i ure 1 is a right-hand side elevation of a su cient portion of a war ing machine to be understood with one emhbdiment of my present invention applied thereto; F ig.2 is

a horizontal sectional detail on 'the line'22, t

Fig. 1; Fig. 3 is a side view of the balance 7 wheel forming a part of the governing o5 means,with some of the adjacent parts; Fig.

4 is anopposite side view, showing the friction connection between the balance wheel and its actuating shaft; Fig. 5 is a vertical sectional detail on the line 5 ,5, Fig. 2, look ing toward the balance wheel.

In Fig. 1, the drivin shaft 1 is provided with the usual fast an loose pulleys, indicated at 2, and in practice there are usually for different speeds, the 76 belt being shifted by a suitable belt-shifter or fork 3 part1 broken out, these parts formingno nove part of the present invention. 'A pinion 4 fast on the driving shaft meshes with an intermediate gear 5. mount- 80 edon the side frame 6 of the apparatus, said gear in turn meshing with and driving a pinion? fast on atransmittin shaft 8 extended across the frame at t e back, the

mechanism for acting upon the threads to draw them from the creel-frame (not shown) andt-o wind them onto a beam'be- 'ing actuated from the transmitting shaft 8'.

None of this mechanism forms any part of my invention herein and for that reason it isnot illustrated, as it is old and of .well known construction and operation. From the above description it will be readil understood that if the beltis thrown onto t e loose pulley the, shafts 1 and 8 and the draft mechanism actuated thereby, will stop quickly, if no means be provided to bring such parts to a gradual stop. I have provided such means and willnow describe one practical embodiment thereof.

. Upon the shaft 8 at anyconvenient location, I key or otherwise fixedly secure a' ratchet 9 and a radial arm 10, and interpose between such parts the hub 11 of a heavy balance whee1'12, the hub-bein mounted to rotate upon the shaft. The h u is embraced by a-suita'ble friction coupling, shown best in Figs. 4: and 5 as oppositely curved arms 13 pivoted on the arm 10 at 14 and embracing the hub, the concave parts of .saidamns being no I faced with leather or other suitable material, and said arms are setup as tightly as ma. be necessar by the" clamping device 15. Thus I provi ea friction connection or coupling between the transmittin shaft 8 and the balance wheel 12, so that w en'power is thrown on to the machine the balance wheel will be rotated in thedirection of arrow16, Figs. land '3, solely by-or through the operation of the balance whee I mount suitable springressed pawls 17 which cooperate with t e' ratchet 9, it being remembered that the latter is fast on shaft 8; The pawls and ratchet are so arranged that they cooperate when the balance wheel has attained its normal speed after the power has been I I and the mechanism actuated by it will be kept in motion, but 'with a gradually decreasm speed, until the energy' of the balance w ee is dissipated and t e entire apparatus comes to rest. Consequently the parts of the machine which act upon the warp threads and pull them along slow down gradually and come to rest with the threads tight enough to prevent the forma-' tion of kinks, because the gradual decrease in the speed of the draft permits the spools to slow down gradually, so that they will not overrun and slacken the threads. From the foregoing description, taken w1th -the drawin it will be clear that in starting up and uring normal 0 eration of the machine the transmitting s aft 8 and the various mechanisms actuated therefrom are positively driven and controlled, but, when the power isthrown off, said shaft 8 and the mechanisms actuated therefrom will be controlled by the governing means and gradually slowed down by the momentum of the balance wheel. Thus by a simple and effective formof momentum governor I am' enabled to obviate the objections pointed out 5 at the beginning-of this specification, and

of the friction couplin On the outer side without in any way interfering with the proper normal operation of the apparatus as a whole.

When the apparatus is started u it is immaterial that the balance wheel sips on the shaft 8 and lags behind, for said wheel has no function to perform at such time.

The friction connection or coupling is set up only enough to im art graduall the re- .5 quired speed to the alance whee, as the shaft, a balance wheel, a friction eou ling function of'said connection or couplin ex tends no further than to put the 'ba ance -wheel in motion and keep it moving while the ower is on the machme.

arious changes or modifications may be made by those skilled in the art withoutdeparting from the s irit and 500 e of my invention as set'fort'i in the claims annexed hereto.'- J

Havin fully described my invention, what I c aim as new and desire to secure by Letters Patent is 1. In apparatus of the class described, a transmittlng member, and normally inactive governing means, including a momentum member rictionally connected with and rotated by the transmitting member when the latter is power driven, to assume control of the transmitting member positively and automatically when the power is thrown ofi and to effect the rotation of said transmit: ting member at a gradually decreasing speed.

'2. In apparatus of the class described, a transmitting member, a driving shaft posi-- tively connected therewith, and normally inactive governing means for the apparatus, including a momentum member fri'ctionally connected with and rotated, by the -transmit-. tin member when the latter is power driven, an a direct and positive connection between the momentum and transmitting members, to continue the rotation of the latter in unison with the momentum member at a gradually decreasing speed when the power is thrown off the drivin shaft.-

3; In a paratus of t e class described,a transmitting shaft, and governing means, mcluding a momentum member frictionally connected with and rotated by the transmittin shaft when the latter is power driven, an a device to positivel and automatically connect said shaft and t e momentum member to rotate as a unit when the power is thrown off to bring said shaft and the momentum member to a' stop gradually and simultaneously as the energy of the momen-' tum member is dissipated.

6. In apparatus 0 the class described, a transmitting shaft, a radial arm and an adjacent ratchet, fast on the transmitting shaft, a heavy balance wheel having its hub loosely mounted on said shaft between said ratchet and arm, a friction coupling carried by the arm and cooperating with the hub of the wheel, and pawls on the latter engaging the ratchet and acting in the direction of normal rotation, said balance wheel being rotated by the transmitting shaft through the friction coupling when the power is on, the stored up energy in the balance wheel acting positively through the 20 In testimony whereof, I have signed my 25 name to this specification, in the presence of two subscribing witnesses.
