Specification of Letters Patent.
Patented Jan. 9, 1917.
Application filed May 26, 1916. Serial No. 100,020.
To all whom it may concern.-
Be it known that I, JOSEPH citizen of the United States, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Power- Transmitting and Speed-Regulating Means, of which the following is a specification.
My present invention pertains to power transmitting and speed regulating means; and it contemplates the provision of simple and efficient power transmitting and speed regulating means designed more especially for use in worsted or woolen mules, twisting machines and the like, and constructed with a view to accommodating the machinery to the condition of the yarn as aflected by temperature and humidity of the atmosphere, it being well known that in the spinning and twisting of yarn the handling of the yarn is affected by the atmosphere and that unless the speed is changed in accordance with changes in the atmosphere breakage of the yarn will ensue.
The invention will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and formin part of this specification in which:
Figure l is a View showing my improvement in side elevation as applied to a mule. Fig. 2 is a plan of the improvement. Figs. 3 and 4 are enlarged detail views of the take-up roll complementary to the cone belt.
Similar numerals of reference designate corresponding parts in all of the views of the drawing As illustrated my improvement is designed to transmit motion from the main roll shaft 1, mounted on the frame 2 of a mule spinning machine, to a counter shaft 3 from which through a driving connection 4 power is transmitted to the feed roll or drum 5 which feeds the roving to the spinning roll.
It is necessary in order to avoid loss in production to change the speed of the drum 5 without stopping the machine, and for the said purpose I provide the reversely arranged cones 6 and 7 on the shafts 1 and 3 respectively, the belt 8 connecting the said cones, the mechanism for shifting the belt lengthwise of the cones, and the mechanism for automatically taking up slack of the belt and retaining the same at all times under proper tension. The belt shifting mechanism comprises a" rack bar 9 fixed to Rocrs'rnn, a
and extending laterally outward from the mule frame 2, a carriage l0 movable outwardly and inwardly on said rack bar and having a depending fork 11 which straddles the lower stretch of the belt 8, a set screw 12 mounted in the carriage and designed to be turned against the rack bar to adjustably fix the carriage with respect thereto, and an upright shaft 13 journaled in the carriage and equipped with a handle 14 and spur gear 15; the spur gear being intermeshed with the rack bar 9 so that turning of the shaft 13 will be attended by outward or inward movement of the carriage 10 according to the direction in which the shaft is turned. Manifestly outward movement of the carriage 10 will shift the belt 8 outwardly with the result that the speed of the shaft 3 will be increased, while inward movement of the carriage and belt will bring about a lessening of the speed of the shaft 3 in proportion to the extent of the inward movement of the belt. The mechanism for subjecting the belt to tension and taking up slack thereof comprises an arm 20 fixed to and extending upwardly from the carriage 10, a roller 21 arranged to bear on the upper stretch of the belt which extends through the open portion of the arm 20, a frame 22 carrying the roller and having a stem 23 guided in the upper bar of said open portion, and an expansion spring 24 interposed between said upper bar and the frame 22 and tending to press the frame 22 and the roller 21 downwardly with a view to taking up slack of the belt and holding the same under proper tension under all conditions of service. From this it will be appreciated that the take-up means constitutes an important part of my invention.
It will be gathered from the foregoing that by the means described the speed at which the shaft 3 is driven can be expeditiously and easily changed without stopping the machine and without impairing the transmitting efficiency of the belt between the cones. It will also be noted that when desired the belt can be adjustably fixed against movement in the direction of the length of the cone pulleys.
Having described by invention, what I claim and desire to secure by Letters-Patent, is:
In means for the purpose described, the combination of a frame, a shaft mounted in the frame, a second shaft mounted in the and inwardly on said lateral bar and between the upper and lower stretches of the belt and having a vertically-disposed shipper receiving one stretch of the belt and also 10 having a vertically-disposed arm extending in the opposite direction from the carriage and receiving the other stretch of the belt,
