Description

UNITED STATES PATENT OFFICE.-
HERMAN sTAUB, or WYOMISSING, PENNSYLVANIA, ASSIGNOR TO TEXTILE MACHINE WORKS, or WYOMISSING, PENNSYLVANIA, A ooRPoRA'rmNoF PENNSYLVANIA.
BRAIDING-CARRIER.
Specification of Letters Patent.
Patented N v. 30, 1920.
To all whom it may concern:
Be it known that I, HERMAN STAUB, a citizen of the United States, residing at Wyomissing, in the county of Berks and State of' Pennsylvania, have invented certain new and useful Improvements 4 in Braidin -Carriers,-
, of which the following is a speci cation.
My invention relates to braiding carriers adapted more particularly for single-thread lace-braiding machines and is fully described in connection with the accompanying drawings, the novel features being specifically pointed out in the claims.
Figure 1 is a central longitudinal section of a complete carrier embodying my improvements in preferred form.
Fig. 2 is an enlarged elevation of the tubu: lar extension of the bobbin standard looking at right angles to the Fig. 1 view thereof.
Fig. 3 is a plan view of same.
Fig. 4 is a partial longitudinal section of the extension showing the top portion of the spring with cap thereon.
Fig. 5 is a cross-sectional view of same. i
Fig. 6 is an elevation showing the lower portion of the carrier with thevstop sleeve in dropped position thereon.
The type of carrier indicated comprises a base portion 10 guided in the race-way plate 11 of the machine, and having a tubular bobbin standard with a thread-tension-- ing spring 12 therein arranged to release a bobbin-engaging" pawl 13. My invention" provides an improved construction and ad-v vantageous operation of the carrier as here-- inafter fully described. I
As shown the base portion 10 is formed with an integral tubular standard portion 15 of circular cross-section; and an upward extension of this standard is provided by a separate tubin having its lower portion 16 snugly inserte in the fixed standard 15. A pawl-supporting bracket 17 rigidly secured to this extension forms a supporting shelf 18 thereon which bears upon the top of the fixed standard 15, and the bobbin 19 inclosing the standard extension rests upon said shelf,
with an intervening distance sleeve20 as required to properly position the pawl-engag-' ing top of any desired length of bobbin. The top of the bobbin standard extension is provided with a thread-guide eye 21, and the thread passes to said eye from the bobbin through guide eyes 22, 23, 24, in the pawl bracket and pawl respectively, engaging a top eye 25 of the spring 12 so as to be tenl cross-section from the cylindrical part thereof which is engaged in the fixed standard 15; it being of square cross-section as indicated in Fig. 5 in the portion 30 inclosing the spring 12, with a side wall cut away in the upper portion 81 thereof to provide passage way for the thread, and with the top portion 32 closed upon the porcelain guide eye 21. The spring 12 is provided with a thread cap 35 having a cross-section at 36 conforming with that of the angular standard extension 30, so as to be non-rotatable in the latter though loosely slidable therein.
The lower end of the spring 12 is provided with a loop 38, which is engaged by a crosspin 39 extendin through longitudinal slots 40 in the top 0% the fixed standard 15 and connected to the stop sleeve 41 on the latter;
so that said end of the spring will also be held at all times against rotative action, with the sleeve free to drop upon any breaking of the thread. Thepawl bracket shelf 18 is formed with 2. depending offset or oflsets 42 engaging the slots 40 so as to positively prevent any turning movement upon the fixed standard.
Important operating advantages result from the positive prevention of spring turning movement which my improved construction provides for. The rapid stretching and contracting of the spring under varying thread tensions I have found to ordinarily produce turning movements of the thread connected end of the spring sufficient to bring the normally approximately parallel portions of the thread into rubbing contact with resulting wear and liability of breakage; and a main purpose and result of my invention is to avoid these effects by positively restricting such turning movement of the thread connected end of the spring as set forth. The improved connection of the lower end of the spring also reduces objectionable. wear and tear ordinarily incident to this turning action of thevariably tensioned spring. A further practical difiiculty largely overcome by my improved construction is clogging of the spring action by accumulation of lint rubbed from the passing thread; the amount of such lint being not only reduced by avoidance of rubbing action,
but the spring cap 35 being also adapted to permit the passage of lint close to the Wall of the standard extension and practically a clear of the spring coil, into the spaces below the spring, from .Which it may be readily re: moved at intervals.
lVhat I claim is 1. A braiding carrier comprising a base portion having a tubular standard provided with a bobbin-supporting bracket, a springguide portion of angular cross-section, and a thread-guide top portion; a thread tensioning spring having a cap of angular crosssection non-rotatably slidable Within said spring-guide portio n, and a stop sleeve nonrotatably slidable on the standard below said bracket and connected to the lower end of said spring.
2. In a braiding carrier comprising a base portion having a tubular bobbin standard provided with a thread-guide top portion and a spring-guide portion of angular crosssection; a stop device non-rotatably slidable on the lower portion of said standard and a thread-carried tensioning spring connected at its lower end to said non-rotatable slide stop and having a cap of angular crosssection loosely slidable in said guide-portion of the standard.
In testimony whereof I afiix my signature.
HERMAN STAUB.
