LOOM SHUTTLE.
Application filed February 28, 1922.
T o all w hom t may Gomera Be-'it known thatI, ALONZO E. RHoADEs, a citizen of the United States, resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Loom Shuttles, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts. f
This invention relates to loom shuttles of the type used in automatic filling replenishing looms wherein when a fresh filling carrier is placed in the shuttle the threading operation takes place automatically. The invention is also allowable in the hand threading type of shuttle. In shuttles of these types the filling is carried by the hand or by the mechanism of the loom during the threading of the shuttle from the filling carrier down through a threading slot and out through the delivery eye of the shuttle, and it is important and necessary that means be provided which will prevent the filling from being thrown or passed out of the filling passage extending from the filling carrier chamber through the delivery eye.
During the operation of the loom the lling is often unwound or slips olf from the end of the filling carrier more rapidly than it is utilized in the weaving of the cloth. This results in ballooning or kinking of the filling in such a manner that it not infrequently works its way up and out of the filling passage resulting either in imperfect work or the stopping of the loom, if it is provided with a filling controlled stop motion, or both.
The object of the present invention is to provide a simple and efficient means for retaining the filling in the filling passage eX- tending from the filling carrier chamber out through the delivery eye and preventing the filling from being thrown or passed out from this passage, while at the same time providing a means which will not interfere with the ready self-threading action of the shuttle.
These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.
Serial No. 539,970.
In the drawings;
Fig. 1 is a plan view of the delivery end of a self-threading shuttle provided with a preferred form of the invention;
Fig. 2 is an end elevation looking toward the right of Fig. 1 of the threading block;
Fig. 3 is a side elevation of the threading block.
Fig. 4 is an end eleva-tion of a detail of the threading block.
The shuttle which may be of any desired or usual type comprises a body ortion l usually formed of wood and having at its ends the metal tips 2. The body of the shuttle is formed with a suitable chamber 3 in which is mounted a filling carrier herein shown as a bobbin 4. The delivery eye 5 is located in the side of the shuttle near the tip.
The passage for the filling from the filling carrier chamber 3 into and out through the delivery eye 5 is usually formed mainly in a separate threading block made of metal and rigidly secured in place in the shuttle. The invention in its preferred form is herein shown as embodied in such a threading block. This threading block is shown separately in Figures 2 and 3.
T he threading block 6 has extending longitudinally therethrough a filling passage7 which connects the filling carrier chamber 3 with the delivery eye 5, this delivery eye being formed mainly in the wooden body of the shuttle in a well-known and familiar y manner. The passage of the filling into the filling passage takes place through a threading slot which in the case of the present invention is a straight longitudinal opening 8 directly over the filling passage. Tn effect this slot is enlarged into the opening 9 formed longitudinally in the upper portion of the threading block. The threading block at the forward end and at the side toward the delivery eye is provided with a depending horn 10, the forward edge of which merges upwardly into a beak 11 at the forward end of the threading slot. The recess 12 formed by the horn 10 in the threading block aligns with and forms a portion 'of the upper wall of the delivery e e.
yTwo rows of pins are inserted in or formed on the threading block and project over the threading slot 8. The free ends of the pins 13 at the delivery eye side of the shuttle stand slightly higher than the pins 14C at the opposite side and the free ends of the two sets of pins overlap, as shown in Figures 1 and 2. This enables the filling as it is drawn into the delivery eye to ride down on the upper surface of the pins 111 and beneath the pins 13. Preferably also as shown the pins at one side are staggered with respect to those at the opposite side. And preferably also the free ends of the pins are inclined slightly downwardly, that is toward the threading slot, and also forwardly or in a direct-ion away from the filling carrier chamber 3 or in other words in the direction in which the filling moves as it is passed into the threading slot.
Vhen the shuttle, as is ordinarily the case, is of the self-threading type used in the automatic filling replenishing loom, the filling after replenishment extends from the tip of the filling carrier a in a substantially straight line over the tip of the shuttle as the shuttle is picked away from the transfer side of the loom. In this invention the threading slot and the guide opening thereinto extend in a straight line longitudinally of the shuttle and this guide opening presents a comparatively wide mouth, as illustrated, so that the filling strand naturally tends to pass down directly and easily into the threading slot. As the shuttle starts on its return trip the filling passes beneath the beak 11 and into the delivery eye 5 and is drawn down beneath the pins sliding down on the top of the pins 14e and thence through the threading slot into the filling passage.
In order that in the threading action the filling strand may pass down between the free ends of the two sets of pins when overlapped the free ends of the pins, 13 in particular, are so shaped or positioned, as by suitably rounding off the free ends, that the angle formed between the pin surfaces, as indica-ted at 15 in the enlarged detail view Fig. et, will enable the filling strand to be guided down beneath the pins.
The invention thus provides a simple and efficient means, in the pins described, for guiding the filling into the filling passage which is of such a character that the opening or guideway for the filling into the threading slot and thence into the filling` passage extends in the line of the natural run of the filling enabling it to pass readily and directly into the passage. The pins also provide a simple and efficient means for retaining the filling in the filling passage and preventing it being thrown or otherwise passed out therefrom. It is found in practice that it is almost impossible for the filling, under the conditions of use to which it is subjected, to work its way past the pins' so as to unthread the shuttle. rlhe invention materially simplifies the construction of the threading block, facilitates the threading action and reduces to a minimum the danger of unthreading.
Having thus described my invention what I claim as new, and desire to secure by Letters Patent, is:
1. A loom shuttle having a. body portion presenting a filling carrier chamber', a delivery eye at one side of the body, a filling passage extending longitudinally of the shuttle and connecting the filling carrier chamber and the delivery eye, and a threading slot extending longitudinally into the filling passage at the top and leading into the delivery eye, together with a plurality of oppositely disposed pins mounted in the body with their free ends overlapping above the threading slot, the free ends of the pins at the delivery eye side standing slightly higher than those at the opposite side whereby as the filling is drawn down into the filling passage and delivery eye it is drawn between and beneath the pins which thereupon act to prevent the filling from being moved or thrown out of the lling passage.
2. A loom shuttle having the construction defined in claim 1 in which the said pins are staggered and in which their free ends are inclined downwardly and away from the filling carrier chamber.
3. A loom shuttle having a body portion presenting a filling carrier chamber, a delivery eye at one side of the body, a threading block mounted in the shuttle between the filling carrier chamber and delivery eye and provided with a filling passage extending longitudinally of the shuttle and connecting the filling carrier chamber with the delivery eye, and a threading slot in the threading block extending longitudinally into the filling passage at the top and leading into the delivery eye, together with a plurality of oppositely disposed pins mounted in the threading block with their free ends overlapping above the threading slot, the free ends of the pins at the delivery eye side standing slightly higher than those at the opposite side whereby as the filling is drawn down into the filling passage and delivery eye it is drawn between and beneath the pins which thereupon act to prevent the filling from being moved or drawn out of the filling passage.
4:. A loom shuttle comprising the construction defined in claim 3 in which the said pins are staggered and in which their free ends are inclined downwardly and away from the filling carrier chamber.
In testimony whereof, I have signed my name to this specification.
