WALTER BIXBY, 013 BOSTON, MASSACHUSETTS, ASSIGNOR TO SHAWMUT ENGINEER- mo COMPANY, OF sn'r'rs.
BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHU- SUPPORTING- MEANS FOR TUBE-FRAME SPOOLS.
Application filed March 7, 1923. Serial No. 623,524..
To all whom it, may concern: I
it known that I, VVAL'rnR BIXBY, a citizen of theUnited States, and resident of Bostoin in the county of Suffolk and State of Massachusetts, hav invented certain new and useful Improvements in Supporting Means for Tube-Frame Spools, of which the following is a specification.
This invention relates to tube frames for weaving and is intended to. provide a simple and convenient construction for mounting the yarn spool in the tube frame in such manner as topermit its quick and convenient insertion and replacement.
, It is customary in constructing tube frames for us on the wider looms tomake the yarn spool in two or .more sections placed end to end with the journals of each section either telescoping one into another, or else havinga butt end contact between two adjacent journals each of which occupy a portion of the length-'of'the bearing recess, and it has been common practice to make a split or separablebearing one part of which is movable away from the other to allow the spool journals to be inserted or taken out. j
I The'present invention, while not precluding the use of asplit bearing, is primarily intended to make possible and convenient the us of an-integral instead of a sectional bearing box, provision being made for the instant and convenient insertion of each spool section as well as for its quick removal. To this end the invention comprises generally in combining with the carrier bar and the yarn spool, a bearing bracket member supported by the former in position to afford bearing support for adjacent endsof the spool sections and mounted to permit movement toward and away from the end of one spool section whereby, after the spool journal is inserted, it may be returned to normal operative position to afford bearing for said spool section and its adjacent section. This and other features of the invention will be more particularly described in the following specification and will be defined in the claims forming part thereof.
In the drawings I have illustrated several forms of construction and arrangement embodying the principles of this invention,
in which:
1 Figure 1 isa front elevation of a tube frame with intermediate parts broken away Figure at is a side elevation of the same.
Figures 5 and 6 are similar views of modified forms of construction.
Figures 7 and 8 are corresponding views of another modified construction of the spool-supporting bracket.
Figure 9 is a detail perspective View showing the fulcral or attaching member for the bracket shown inFigures 7 and 8, and
Fig. 10 is a horizontal sectional view of the structure of part 36 of Fig. 7.
In the practice of this invention, according to the form illustrated in Figure 1, the carrier bar 1, is provided with the usual suspension hangers 2, by which it is suspended from the overhead carrier chains which deliver it to the transfer mechanism for use in the looms. Along the front face of the carrier bar 1, is mounted a series of individual tuft needles or guide tubes through which the yarn from the spool is delivered to the fabric in the weaving process. rigid suspension hangers 2, are provided with upwardly extending ears 2 which afford bearings for the journals 5 and 6 of the yarn-spool SQCtlOiiS 4.
The
According to the illustration of the drawingaone journal 5 is a fixed or rigid journal projecting into the bearing ear 2*, while the other journal 6 is a telescoping springpressed journal mounted in a recess 4 in the spool so as to be pressed inwardly to allow its insertion into the closed bearing ear 2. At their adjacent end, the two interlocked spool sections are provided, respectively, with journals of any suitable con struction which, in this case, are shown as comprising ajournal7 provided with a mortiseil recess 7*" adapted to receive the tenon 8 of the yarn journal or gudgeon of the adjacent section .in order to secure unison in rotation as the yarn unwinds. In this case, as the gudgeon 8 telescopes inside of the journal or gudgeon 7, the bearing which supports the adjacent ends of the spools is made ofa size to fit around the gudgeon 7 but, ob-
rotation for the delivery of yarn, a pivotal bearing bracket interposed between the adacent ends of two spool sections and mounted to swing about an axis transverse to said carrier-bar, a spring arranged to yieldingly maintain said bracket in normal bearing position, and a stop member arranged to oppose and limit the spring-actuated pivotal movement of the said bracket to prevent endwise pressure of the bracket againstits supported spool section, substantially as described.
7. In a tube frame for tuft weaving, the combination with a carrier-bar, of a rotatable sectional yarn-spool whose sections are arranged end to end, an intermediate bearing bracket movable away from one spool section to permit its removaland normally pressed toward said spool section by a yielding spring, and a stop member arranged to limit the pivotal movement of said bracket whereby the bracket is normally maintained in and restored to operative position without exerting axial pressure on either adjacent spool section, substantially as described. 7 8. In a tube frame for tuft weaving, the combination with a longitudinal carrier-bar, of a sectional yarn-spool rotatably supported thereon, an intermediate bearing bracket interposed between two adjacent yarn-spool sections and comprising parallel plates secured together side by side, and a bearing bushing inserted through registering apertures in said plates to support the spooljournals, substantially as described.
In witness whereof, I have subscribed the above specification.
WALTER BIXBY.
