This invention relates to an attachment for textile machines.
In the standard textile machines or looms, there is a plain bar or support for the lock elements or finger trips to rest on and be disengaged therefrom. This ordinary support or bar is stationary and as the result thereof, the lock elements or trip fingers soon wear a notch in the bar. These lock elements are caused to trip about every five minutes. This results in the forming of a notch, or notches, on the bar. Before too long this notch has worn so that the lock elements or finger trips will be tripped b the looms vibration. When so tripped, it throws an unfilled and also a filled bobbin, to replace it. Sometimes the trip device will fail to trip when the empty bobbin signals for a change to a full bobbin. In this case the bar being out of line with too much pressure against the finger trip causes the same to hang. This allows an empty bobbin to pass through the warp, resulting in a cloth imperfection. The finger trips or look elements should hold to an adjustment that throws out a, bobbin just as it is empty, then throws in a filled bobbin. Premature or out-of-time tripping of the finger trip, even with new and well adjusted assembly, is not unknown.
Therefore, to overcome the above weakness and unsatisfactory construction of the present day loom, an object of this invention is to provide the support or stationary bar of a loom that is engaged by the lock elements or finger trips with a rotatable sleeve, orsleeves, whereby an efficient structure is provided, both as to operation and durability.
Another object of the invention is the provision of an attachment on the stationary support or bar that not onl has a minimum amount of wear, but which will adjust itself to place a wide bearing surface in the arc of the finger trips path. The wide surface of this attachment presents a well aligned stop to the finger trip or lock element, as well as a full bearing surface; further, the rotatable sleeve, or sleeves, gives the finger trips a more sudden trip movement.
With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter full described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.
In the drawings:
Figure 1 is a vertical, fragmentary, sectional view of a textile machine, showing my invention applied thereto, taken on line I-l (Fig. 2) and looking in the direction of the arrows.
.i'sa-zszy V,
Figure 2 is a top'plan view of the structure illustrated in Figure 1.
Figure 3 is a perspective, exploded view of the attachment constructed in accordance with the present invention.
Referring to the drawings, in which the preferred embodiment of the invention is illustrated, i designates a frame on which is mounted a, shaft 2. On shaft 2 are a pair of dog controlling latches 3. Each latch 3 is provided with a pivotally mounted lock element or finger trip 4. This structure is common to that disclosed in U. S. Patent No. 2,054,192.
A stationary support 5 is provided, which may be a bar or bolt threaded near its two ends, as clearly shown in Fig. 3. This stationary support 5 is mounted on frame l. Outside of frame I are two nuts 6 that are threaded 0n the projecting ends of stationary support 5 and bear against the outer faces of the sides of frame I, Fig. 2. Mounted on the stationary support 5 are two sleeves I. The two sleeves I are necessary because in multi-shuttle automatic replenishing loom there are two shuttles, and consequently there is a sleeve for each shuttle and its coopcrating parts. It is also to be understood that the two shuttles do not work at" the same time; consequently two sleeves are necessary.
Each sleeve has on its inner end an integral collar 8; these collars are in engagement when the sleeves are mounted on the stationary support 5, Fig. 2.
For efficient results, each sleeve is hexagonshaped, which provides efiicient surfaces to be engaged by the inner ends of the lock elements or finger trips A. The term hexagon is used meaning an angular-surfaced sleeve. The description and objects at the first part of this specification explain the full value of this attachment.
The term bar or bolt is used in a broad sense in this specification, meaning any suitable support.
It is to be noted that by reason of the finger trip 4 engaging a, fiat surface on the sleeve, a very efficient contact is made, per Fig. 1. Further, every time the finger trip is operated a new contact surface onv the sleeve is brought into use reducing wear and thereby increasing the life of the sleeve, or sleeves.
While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
What I claim is:
1. In a multi-shuttle automatic replenishing loom, the combination with a. frame having fixed sides, a bar supported between said sides, a pair of sleeves rotatably mounted on said bar and having polygonal exteriors, a pair of finger trips mounted in said frame and having lock elements at their inner ends engageable with the polygonal exteriors of the respective sleeves to prevent rotation thereof.
2. In a multi-shuttle automatic replenishing loom, the combination with a frame having fixed sides, a bar supported between said sides, a pair of sleeves rotatably mounted on said bar and having polygonal exteriors, a pair of finger trips mounted in said frame and having lock elements at their inner ends engageable with the polygonal exteriors of the respective sleeves to prevent rotation thereof, said sleeves having integral collars at their adjacent ends, said collars being in contact t permit each sleeve to rotate respective to the other.
TILDEN M. CARMICHAEL.
