ALONZO E. RHOADES, 0F HOPEDALE, MASSACHUSETTS, ASSGNOR TO IDRAPER CGR- PORATION, OF HOPEDALE, MASSACHUSETTS, A CORPORATION OF MAINE.
AUTOMATICALLY-THREADING SHUTTLE FOR LOOMS.
Application filed November 7, 1925. Serial No. 67,525.
1o al?, whom t may concern:
Be it known that I, ALONZO E. RHOADES,
a citizen of the United States, residing in' I-lopedale, in the county of Worcester and State of Massachusetts, have invented an Improvement in Automatically-'Ifhreading Shuttles for Looms, of which the following description, in connection with the accompanying drawings, -is a specification, like characters on the drawings representing like parts.
This invention relates to automatically threading shuttles for looms and is directed more particularly to the threading block, whereby, during the operation of the loom, the shuttle may be threaded.
In'the patent to .Edward S. Stimpson, No. 1,538,224, May 19, 1925, there is shown and described a threading block for automatically threading shuttles, formed of cast iron having the thread engaging surfaces thereof covered by a rust-proof covering, and shuttles provided with such threading blocks have gone into extensive use with satisfactory results. The cast iron threading block is very hard and not capable of being satisfactorily worked or bent, and in connection with such threading block the shuttle is usually provided with a threading block receiving chamber in which the threading block is secured. It is sometimes desirable to tit the threading block into the threading block receiving chamber of the shuttle, without, however, materially altering the shape of the chamber itself or cutting away the wood of the shuttle, and one of the objects of the present invention is to provide a threading block formed in part of cast iron having a rust-proof covering on the thread engaging portions, and in part of a softer metal which may be readily worked or bent, if desired, in order to lit the block accurately to thevshuttle chamber and t0 alter the shape of certain portions of the block to adapt it for accurate loom threading and subsequent weaving.
In accordance with one aspect of the present invention, the threading block is formed of two parts, although the number of such parts may be varied, and one of such parts, the main portion of the threading block preferably, is formed of cast iron with a rust-proof covering which oifers n0 objectionable obstruction to the movement of the thread during weaving, and associadapt the block to the threading block rcceiving chamber and the parts of the block to the shuttle wood. Threading blocks of the present invention, while adapted to new shuttles, present many advantages to renewals, that is, where an old wooden shuttle has been worn out or has become unserviceable.
The invention and new combination of parts will best be made clear from the following description and the accompanying drawings of one good practical form thereof wherein the threading block is formed of two parts, one of which is cast iron and the other of which is of al softer metal.
In the drawings:
Fig. l is a perspective view of the threading end of a shuttle provided with the present invention;
Fig. 2 is a perspective View of the main portion of the threading block which is formed of cast iron having a rust-proof covering Fig. 3 is a detached view of one good form of thread casting device which may be employed in connection with shuttles of this general type.;
Fig. 4 is a perspective view of that part of the threading` block which is formed of softer metal than cast iron and preferably brass which may be readily worked or bent to shape;
Fig. 5 is a side elevation of the threading block detached and with the cast iron and softer metal parts in their assembled relation;
Fig. G'is a section on the line G-G of Fig. 5; and
Fig. 7 is a threading block constructed in accordance with the present invention but showing a modification.
The. shuttle l may be of usual character for supporting the filling carrier or bobbin 2 and, as usual in such filling replenishingl shuttles, it is provided with a bottom opening 3 for the ejection of the filling carrier on replenishment.
At the front end portion of the shuttle. that is the end of the shuttle containing the side delivery eye, the wood of the shuttle is cut away to provide a threading block re ceiving chamber 4; in Which the threading .block constituting the present invention may be secured. e vw In its broader aspects the present invention aims to provide a ,threading block formed partly of cast iron having a rustproof covering on the thread engaging Vpor- .tions thereof, and in part of a metal softer than the .ca st iron which may be readily worked vWhile cold intol the desired shape`- should a change in such Shape be required by the shuttle 4to which the threading block is applied.
, As shown 1n the present instance of the invention, the main portion of the threading block, as indicated ink Fig.4 2, is formed of cast iron having a rust-proof coyering on the thread engaging portions thereof. The main portion of the threading block, as indicated in Fig. 2, is formed of a bottom 5 and a side Wall 6, shown as casty integral in the'present instance, and providingbetween the tivo a longitudinally extending thread passage'?. At the front of the thread passage 7 is the bridge 8 over which the thread passes during weaving on its Way to the side delivery eye, and the 'cast iron part of the threading block, in lthe present in stance, is provided with asu'pportingshoul Ider 9 lwhich underlies a horn ofthe softer metal as will presently appear. The shoulder 9 is cast with the main -portion of the threading Eblock and is provided with a relcess or guide l0 under which the thread f'passage.. .Below the thread'director l2 the sidef'portion is providedwvith a recess 14 shaped to fit the shoulder 9, so that the side Vportion l1L which is formed of soft lmetal rests upon the cast iron shoulder 9"and'finds support thereon. .The construction of the lmain portion of the threadingbloclgrthat formed of cast iron is shown in Fig. 2, and the side portion ll of the threading -block which is formed ofsofter metal such as brass, may bewvariously contrived, but the construction hereinbefore described is found to be a good practical embodiment of the invention.
, The side .portion 11 of softer'metal is also arovided with a recess 15 on its inner face which encloses; a lug 16 formed on and preferably cast with the cast iron portion ofthe threading block, as indicated in F ig. 2, and
the thread casting device serves for the pasa pin 717 serves to properly position the parts indicated in Figs. 2 and 4 to bring them `into registeringrelation by means of the hole 18,:i11` the,sidellportion l1.
ABoth tliei'cast'irn part of the threading 70 blockandtliesattermetal Side Portion 11 thereof are provided With openings 19 and 20.-.respectively.. tolrreceive the transversely extending securing bolt 2l whereby the parts of the block intheirv assembled relation may b e vsecured in the threading block receiving chamber of thefshuttle.
Theside. portion 1 1 above .the recess 15 has ashoulder I22 which rests uponthe top 423fof the lug 1G of the cast iron part of the S0 block. l
j lVhenthev parts lare assembled with the interengaging recesses. and projections herelinbeforeA described, they are maintained rigidly in assembled relation When inthe 35 threadlng block receiving chamber ofthe shuttle, and while'th'e particulars and. details liereinbefore described lare Well-adapted for a threadingblock f ormedin. part of Ic'ast iron with a rust-proof covering and in. part of a softer-metal that may beinorereadily )vorked,it is' to be understood'that applicant regards himself as being/.the lirst in ythe art to pro-vide .a threading block for automatically threadingfshuttles .formedin separate pai-ts, one'of ycast iron having trust-proof covering.and'the other of fasoftermetal which maybe 'more'readily Wolrked'or bent to=shape While cold,.such as brass.
lThe threading block herein shown and described may be advantageously employed Vin connection With a thread castingdevicefor vcast-ing thethread on vthe occurrenc'eof. a
loop. orvoverthroiv, and.-in the present instance of the invention the thread casting device is shown 'as' a scroll. 24, illustrated separately in- Fig. 3, which lhas a'foot portion 25 .f adapted to underlie the rabbeted portion 26 formed inthe cast iron'. part yof the A.threading block. In the present instance, the-thread. guiding device has an opening 2T throughWhich thetra'nsverse bolt'Ql may lpass vto secureuthe thread .casting device, in
position'in .the thread passage, and in order that the thread lcasting deviceinay be .supported indifferent positions longitudinally ofA the.,thre'ad Ipassage, .the opening 27. is
I'formed duplex. ABy passing the transverse bolt 21 through .the parts of' the threading' block and through the rear opening 2T .of 120 .-the'threadcasting device, v.the flatter will be 'further frontward in fthe .longitudinally eX- Atending thread passage,l Whereas, w'hen the front or other ,portion 27,'of the opening iin-1o U sageof the transverse bolt 2l, the thread casting device will be nearer the bobbin chamber.
Thefsofter metal side member l1 as heie. inbefore described, not only has the thread Cil director 12 Hwith its 'transversely' extending end portion 13 but, in the present instance, has the apron'28A which-extends laterally from the thread passage and -overlies the side delivery eye, substantiallyas is usual in the aprons of the prior art.
Where the threading blockis formed of two parts, "as 'indicated in Figs.- 2 and 4, one of cast ironyan'd the other of softer metal, the cast iron portion provides a wall 6 atone side of the longitudinally extending thread passage, While the side'member 1l of the softer metal constitutes tlieopposite side wall of the longitudinally extending thread passage, -andfif desired ithe. two walls may be substantially co-extensive.
lt is sometimes desirable to provide a horn extending from the side member ll of softer metal, as indicated in Fig. 7, and in such case the side member ll is extended somewhat further towards the bobbin chamber, as indicated in Fig. 7, and at its portion adjacent the bobbin chamber it is provided with the laterally extending horn 29, the purpose of which is two-fold; first, to take control of the thread on the first pick following replenishment should the thread fail to pass into control of the thread casting device; and, second, to act as a leader for the thread on the second pick following replenishment should the shuttle be only partially threaded. This latter function is performed by the concave front surface of the horn 29 over which the thread may pass on its way from the bobbin to the cloth vage on the second pick following replenishment.
The pin 17 when used to unite the cast iron and soft metal parts of the threading block may extend through both portions 5 and 1l, as indicated in Fig. G, with the ends of the pin Hush with the outer surfaces of the side walls, and while such pin is desirable in many cases, its use is not indispensable because the cast iron portion of the block and the softer metal portion are both held in the theading block receiving chamber by the transverse bolt 2l, and said two portions of the threading block have inter-engaging supporting surfaces as hereinbefore described.
lVhen applying the two-part threading block of the present invention to the wood of a loom shuttle, should itl be found that. some change or alteration is desirable 1n the threading block to cause it to properly fit the threading block receiving chamber in the shuttle, the softer member 1l of the threading block permits ready working of said part as by filing or grinding or bending, so that the threading block may be readily adapted to the conditions of the shuttle.
