ROTARY MAGAZINE FOR LOOMS.

Specification of Letters Patent. Patented pgq 16, 1919 Application filed May 27, 1919. Serial No. 300,087.

To all whom it may concern:

Be it known that I, ALONZO E. RHOADES, a citizen of the United States, residing at I-lopedale, county of Worcester, and State of Massachusetts, have invented an Improvement in Rotary hlagazines for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the draw ings representing like parts.

The present invention relates to improvements in the rotary magazines of weft replenishing looms, such magazines being adapted to hold a large number of weft carriers or bobbins which are to be transferred one by one into the working shuttle; and the improvements more directly relate to the means for maintaining the bobbin engaging ends of the heads of the magazine in alincment parallel with the axis of the shut tle to which the weft carriers or bobbins are to be transferred. Heretofore, the heads of the rotary magazine were mounted upon a support for rotative movement to carry the filling carriers or bobbins one by one to the transfer position. at which time, the longitudinal axis of the bobbin which is to be transferred to the shuttle must be parallel to the longitudinal axis of the shuttle, otherwise damage is liable to result either to the shuttle or carrier or other parts of the loom. Such rotary magazines are usually designed to have the heads thereof adjustable relatively toward or away from each other to adapt the magazines to bobbins or filling carriers of different lengths. but when the heads have been thus adjusted. the alinement of the bobbin end engaging means on the two heads -are liable to he accidentally moved out of their alined position, with the result that when a. filling carrier or bobbin positioned for transfer itsaxis would not coincide with or be parallel to the longitudinal axis of the shuttle. and damage would result as above indicated.

In accordance with the present invention, the rotary magazine has the heads adjustable toward and from each other as required. and means are provided to prevent relative rotative movement of the heads of the magazine during the time the heads are adjusted toward and from each other, the result being that the bobbin end engaging means carried by the two heads remain in their original a-linenient parallel to the longitudinal axis of the shuttle into which the filling carriers are to be transferred.

In accordance with another feature of the present invention, the parts of the magazine are so formed and related and connected to the rotary, thread guide that when the rotar thread guide is removed from the magazine, one of thebobbin holding heads of the magazine may be removed with it Without disturbing the relative rotative position of the head and the rotary thread guide with which it is associated.

Other features of the invention in addition to the above will hereinafterbe described in connection with the accompanying drawings which illustrate one good practi cal form of the invention, and then the novel characteristics and combinations Will be described by the claims.

In the drawings p v Figure 1 is a vertical longitudinal section of a rotarymagazine for filling replenishing looms containing the present invention;

Fig. 2 is a transverse section on the line 22 of Fig. 1. H

In its general features they rotary magazine and its cooperating relation with other features of filling replenishing looms may be generally similar to the well known Draper or Northrup loom, as illustrated, for example. by Letters Patent of the United States. X0. 529.940, November 27, 189- and upon such general features of the rotary magazine the present invention improves.

As indicated in the accompanying drawings. 1 is a stand or bracket fixed to a stationary part of the loom, and in the present instance it is formed as a disk-like member in which isvmounted the supporting stud' 2. The supporting stud 2 isprovided with a shoulder 23 which bears against the hub-like portion 4 of the stand. and the outer end portion 5 of the supporting stud is provided with screw-threads on which is placed the clamping nut 6 whereby the supporting stud is .held in fixed position relative to the stand 1.

The supporting stud 2 may be variously contrived, butas indicated in the present instance, it has the barrel-like portion 7 and the extended end portion 8 on which is mounted for rotation the elongated sleeve 9, against the end 10 of which a washer 11 rests under the'clamping action of the nut 12 threaded to the end of the stud 2, the construetion being such that the sleeve 9 may be rotatively supported upon the support-' ing stud, a shoulder 18 afi'ording one good suitable mea or preventing relative longi tudinal movement of the sleeve on the stud.

The sleeve 9 is provided with a large interior chamber 11 surrounding the large cylindrical part 7 01 the stud and affording an oil receptacle for the transmission of lubricant between the sleeve and stud. The stud :2 is provided with a longitudinally ex tending duct 15 and a radial portion 16 communicating with the large interior chamber 14. Exterior to the duct 15 is an oil receiver 17 having communication with the duct 15 for the transmission of oil to the large chamber 1% of the sleeve.

One of the heads of the magazine is rigidly connected with the sleeve 9. In the resent instance of the invention, the head 18 which is provided with sockets 19 or other means for engaging the butt ends of the bobbins is rigid with the sleeve 9, preterably by being formed integral therewith, it being obvious, of course, that the rigid connection between the sleeve and head may be otherwise contrived. The head 18 may be provided with the usual ratchet teeth or other means 20 for giving rotary movement of the head and sleeve as the filling carriers or bobbins are moved to transferring pos1- tion.

The elongated sleeve 9 has an end portion 21 of reduced diameter forming a shoulder 22 against which bears one end of the elongated hub 23 carrying the rotary thread guide 24. The rotary thread guide and its hub are suitably connected to the sleeve 9 to rotate therewith by appropriate means, which in the present instance of the invention, consists of a clamping screw 25 passing through the hub and engaging a substantially fiat surface 26 on the sleeve, the construction being such that when the parts are assembled as indicated, the bobbin end engaging means on the two heads of the magazine will be held in alincment with the axes of the bobbins parallel with the longitudinal axis of the shuttle.

The other head of the magazine indicated at 27 is provided with a series of bobbin end engaging means for engaging the tip ends of the bobbins. In the present instance these are shown as the yielding fingers 28 which may be of usual construction. The magazine head 27 is mounted on the extended hub portion 23 of the rotary thread guide, and the hub 29 of the magazine head 27 is provided with a key-way 30. T he extended hub '23 is similarly provided with a key-way 31, and a kev 32 engages the keyways of the hub and the head to prevent relative rotative movement between the two, and permit longitudinal adjustment of the head '37 on the elongated hub 23 oi the rotary thread guide.

When the magazine head 27 has been adjusted toward and from the opposing head 18 in accordance with the requirements of the bobbins being' used, it may be clamped or held in such adjusted position by suitable means. such. "for instance, as tl clamping screw 33 which passes through the hub Q" of the head 27 and engages the elongated hub 2?) of the rotary thread guide. The construction is such that when the rotary thread guide 2+ and its hub 22- have been adjusted and secured in position upon the sleeve 9, the bobbin end engaging means of the

heads

18 and 27 will be in alinement to maintain the bobbins with their longitudinal axes parallel to the longitudinal axis of the shuttle. It, now, it be desired to adjust the heads '18 and 27 relatively toward or from each other, it is only necessary to unelamp the screw 33 and move the head 27 longitudinally upon the hub 23 of the rotary thread guide, and during such adjustment, the connection between the head 27 and the hub 22% of the rotary thread guide. maintains the head 27 from rotary movement relative to the head 18, with the result that the previously established alincment of the bobbin end engaging means which supports the bobbins with their axes parallel to the longitudinal axis of the shuttle, remains umlisturbed. If it is desired to remove the rotary thread guide and its connected magazine head 27, it is only necessary to manipulate the clamping screw 25, whereupon the rotary thread guide, the hub 23 and the head 27 may be removed as a unit.

The hub portion of the rotary thread guide may be provided with an enlarged socket 3+ for the accomniodation of the clamping washer and nut 11 and 12, and likewise with a longitudinal bore for the acconnnodation of the end 35 of a thread holder 236 about which the ends of the threads leading from the bobbins will be wound. A clamping screw 37 serves to se cure the thread holder f'ili to the rotarv thread guide.
