` Applikation nina March so, isss. (no maei.;

like letters on the drawings representing like parts. l
The invention herein contained is an im provement on the McGovern jack, represented in United States Patent N o. 118,784, dated' April 18, 1871; and it has for its object to enable the speed of the carriageto be made fast or slow/during that portion of the inward movement of the carriage while the yarn is being twisted. In the patent referred to, a long rod, provided `with, a lrack and a` hook, is moved toward the head-stock by a loose pinion engaged by a clutch on a short upright shaft deriving its movement from a worm on a gear, loose on the drawing-out scroll-shaft, the latter gear being driven in unison with the main As this rod is drawn toward the headstock it draws with it the carriage. The hook at the -end of this rod engages a stud on an arm pivoted on a bracket on the carriage.
This stud during the outward movement of the carriage engages the hook ofthe long rod and draws the latter away from the headstock, Athus placing the same in position to operate the carriage when it is to be started in,
and move it while the yarn is being twisted.
By the rod used in the said jack the speed of the, carriage during the commencement of its inward run must remain the saine, and variations in speed cannot be made to adapt the movement of the carriage to the size of the yarn,"it being necessary for the most perfect work to increase the speed of the carriage as the yarn increases in diameter." To do this is the chief object of this my invention; and in the present embodiment thereof I have divided the long rod referred to and shown in the said patent, and have placed between its severed ends a radius-bar secured to the door or fixed with relation to the carriage, and have made whereby I am enabled to regulate the speed of the carriage while running in and twisting the yarn, to correspond with the diameter thereof.
Figure l represents in partial sectional side elevation a sufficient portion of a jack, taken in connection with the mechanism illustrated in the said patent, to enable-one conversant therewith to understand my invention. l Fig. 2 is a plan or top view of Fig. l, the framework of the carriage being omitted except that part of it below the dottedline :vm in Fig. l, the said figure also showing the clutch and worm-wheel or gear aboveit partially broken away; andFig. 3 is-a section on the dotted line y'y, of Fig. 2."
The loose pinion T3, shown in Fig. l in dotted lines, the clutch T2, shaft T', small wheel or gear T, worm Q2, the carriage B, bracket BZ, lever n', stud n, rod or link n2, arm o', rock-shaft o, arms oz and o, gear Q, shaft It', and rack S, are all substantially as in the said patent, and each may be operated as inthe said patent, but instead of the rack S forming a rigid part ofthe long` rod, as in the said patent, I have pivoted the said rack to a part oi'I the rod. In the patent referred to the long rod is marked S". In this my invention I have changed the construction of such rod by dividing it to form parts S, a, and b. The part b is provided with a hook, b2, to engage the stud n, as did the hook on the long rod S in the said patent. The end of the part b nearest the head-stock is pivoted upon a stud, b3, adjustably attached to a radius-bar, b4, pivoted at its end, b5, to the iioor. The radius-bar b4 has a series of holes, 2, either of which may receive a pin, c2, by which to connect the part a with the said radius-bar in an adjustable manner, and the opposite end of the part a is pivoted to the rack S by a pin, cH The purpose of the parts S a b b" and their co-operating devices is to movethe carriage B, to compensate for the shortening of the yarn by reason of the twist put into it; and I therefore denominate the parts Sa b b4 as the easing-up?` devices, they easing up the tension on the twisted yarn.
I have shown the easing-up device or connection between the head-stock and carriage,
as made adjustable, and the speed of the carriage may be regulated by connecting the part c to the radius-bar Z2* more or less remote from its pivot, the farther the pin from the 5 pivotal point of the radius-bar the slower thev movement of the carriage, and vice versa. By moving the pin b3 into one of the holes?) of the radiusbar bnearer its pivot, the distance traversed by the carriage is lessened and its Io speed is reduced, and vice versa. The speed of the carriage coincides exactly with the speed of the rack S when the said rack and the parts a b are' in direct line.
Having shown the easing-up device applied` I 5 to one well-known form of jack, I desire it to be'understood that the saine may be applied,
with slight modifications as to the rack and hook to other forms of jacks or mules.
Prior to this my invention I am not aware that the carriage, or a part connected therewith, has ever been temporarily engaged by a hook or other movable connection, and been drawn in positively for a Short distance, or while the twist was being put into the yarn, 2 5` such device being made adjustable, to thereby enable the speed of the inward movement of the carriage to be varied according to the diameter or size of the yarn being spun.
The speed of the carriage may be accelerated or retarded by adjusting the pins in the holes 3o of the arm b".
I claim- The radius-bar and the part b, adapted to engage a stud made movable with the carriage, combined with the part a, connected with the 3 5 said radiusbar, and with suitable means to draw the said part a toward the head-stock, the point of connection of the radius-bar with one or both of the said parts being adjustable, whereby the speed of the inward movement of 4o the carriage while twisting the yarn may be regulated according to the size of the yarn, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two sub- 4 5 scribing witnesses.
WILLIAM F. TURNBULL.
