Application filed. March 9, 1825. Serial No. 14,230.
and the break remains undetected for a' time while the machine is running, with the result that the broken slubbing becomes wrapped round the spindle and lifts the upper bearing gradually out of the supporting bracket.
According to the invention an upper support for each spindle of a worsted drawing frame or analogous machine is provided with a positively operating locking device which engages the upper bearing of the spindle to prevent the spindle from rising out of its Working position and which is adapted to be rendered non-effective when it is desired to doff.
In one constructional form of the inven tion the collar usually supporting the spindle at its upper end is formed with an annular groove, and transversely of the supporting bracket there is arranged a movable member such as a latch or pin adapted normally to lie in the aforesaid annular groove so as to obstruct upward movement of the collar and to be released from said collar, when necessary, so as to permit freedom of movement of the collar for the purpose of detaching the spindle from the supporting bracket as when dotting.
The said latch or pin may be maintained by gravity normally in the operative position, and means may be provided which serve to indicate the free position of the parts when the latch or pin is actuated.
The invention is illustrated by way of example in the accompanying drawings, in which the mounting of a single spindle is shewn. Figure 1 is a side elevation, partly in section, and Figure 2 is a front elevation.
A is the spindle on which is fitted the fiyer 15 as usual, and C is the neck of the spindle which rotates in a stationary sleeve D of which the diameter of the upper portion D is greater than that of the lower portion, with the result that at about midway of its length the sleeve D presents a shoulder D The sleeve 1) is received between the jaws it, E, formed by the bifurcated forward end of a bracket F suitably'secured to a fixed rail G, said jaws E, E, being separated sufliciently to just permit of the passage therebetween of the lower part of the sleeve D which is of smaller diameter and having a recess in their upper face of a diameter suiiicient to accommodate the upper part D of the sleeve D which is of larger diameter. The jaws E, E form a seating for the shoulder D and thus support the sleeve D vertically. The spindle A is supported vertically at its lower end (by means not shown) in the operative or spinning position. The sleeve D may be pinned or otherwise suitably secured against rotation in the jaws E, E. Q
The upper part D of the sleeve D, which is of larger diameter, is formed with a cir-.
cumferential groove D and through a passage bored transversely through the rear upper part of each of the jaws E, E, there is passed loosely a latch or pin H which is substantially cylindrical in cross-section and adapted to fit within the aforesaid circmnferential groove D J is a Weighted handle attached to or formed on the latch or pin H and suitable means (in the presentinstance shown as a cotter-pin K extending through a transverse opening in the pin H) is provided for securing the latch or pin H against longitudinal displacement.
The latch or pin H, approximately midway of its length, is formed with a flat H of such depth and length that when the latch or pin H is rotated to present the flat H opposite to the groove D the obstruction oflered to the vertical displacement of the sleeve D between the jaws E, E by engagement. of the pin H in the circumferential groove D is removed.
L, M, are limiting stops formed on or carried by the handle J and the bracket F, respectively, and which serve to indicate the exact angular position of the latch or pin H in which the flat H is in a vertical position and the rounded portion of the pin H is disengaged from the groove D of the sleeve or collar D.
Normally the weighted handle or lever J serves to keep the latch or pin H in engagement with the groove D Therefore during the spinning or drawing operation the sleeve or collar D is prevented positively from being displaced vertically and consequently cannot rise up out of the bracket and thus cause the spindle to lose its upper support, even though the slubbing may break and become wrapped round the spindle.
When, however, it is desired to dofi' the spindle it is merely necessary to move the handle J until the stops L and M are in contact whereupon the flat H of the pin H is brought opposite to the groove D and the sleeve or collar D may be moved upwardly until the wider part D is clear of the upper ends ot the jaws E, E, after which the collar D- can be withdrawn from the drawing-box by being passed forwardly through the space between said jaws E, E.
The above described construction is illustrative of one typical example and the design, but it is to be understood that the construction and operation of the parts may be varied without departing from the spirit of the invention.
What we claim is 1. An upper support "for spindles of worsted drawing frames and analogous ma chines, comprising an upper bearing for a spindle, a support having partially embracing means in which the said bearing is mounted, and adjustable means carried by said partially embracing means normally engaging the said bearing and operable to be disengaged from the bearing when it is desired to effect a dotting operation.
2. In worsted drawing frames and analogous machines, a bracket, a spindle bearing supported by said bracket and having two external diameters, that part of said bearing which has the larger diameter having a peripheral groove, and a latch extending substantially at a right angle to the axis of said bearing and normally engaging said annular groove, said pin being movable at will out or engagement with said groove.
3. In a worsted drawing frame or the like, a spindle, an upper hearing for said spindle having at its upper portion. a collar of larger external diameter than its remaining portion, a support for said hearing comprising a pair of jaws spaced from-one another a distance approximately equivalent to the external diameter of the lower portion of said bearing to permit said lower portion to pass therebetween and also having a recess in their upperportion to receive said collar, and a latch associated with said jaws and shiftable into and out ot' engagement with said collar.
Apparatus according to claim 3 bodying means normally maintaining latch in engagement with-the collar manually operative to release saidlatch.
In testimony whereof we aitix our signatures.
