SHUTTLE BOX FOR LOOMS.
APPLICATION FILED JAN- 2. I920.
Patented May 3,1921.
UNITED STATES.
PATENT O E- cYRIL AvALL-E, or WEBSTER, iv assaoriusnrrs.
sHo'rrLE-Box For; Looms.
To all whom it may concern:
Be it known that I, CYRIL 'LAVALLE, a citizen of the United States, residing at Webster, in the county of Worcester and Commonwealth of Massachusetts, have invented anew and useful Improvement in Shuttle-Boxes for Looms, of which the following, together with the accompanying drawings, is a specification.
My invention relates to shuttle boxes for looms and has for its object to provide certain improvements in the mechanism shown and described in United States Let-- ters Patent No. 1,296,697, for a loom, issued to me on March 11, 1919 jointl with Arthur F. Raymond and Alphonse Mhthieu.
The mechanism covered by the above described patent is associated with the picking mechanism of a loom and provides means for retaining and gripping the shuttle thread each time the shuttle is sent fully home in the shuttle box, so that therporpinion which carries a rod extending to the open end of the shuttle box. This rod 1s" provided with a bent overportion which clamps the thread against the wall of the shuttle box each time that the arm and its pinion is turned by the entrance of a shuttle therein. While the above described construction operates satisfactorily in principle,-
nevertheless the pivotally mounted" arm is liable to get out of mesh with its pinion owing to the fact that no provision is made for adjusting its travel. A further defect of the above described construction lies in the fact that the binders oftheshuttle box must be removed in order 'to apply the arm and pinion thereto.
By my invention I propose to greatly improve the above described construction by providing a slide for turning the pmion, the amount of travel of the slide being controlled by suitable :l'djusting means. I further provide a separate frame for carrying the se e l slides and pinions which s Specification'of Letters Patent.
adapted to be applied to the loom as a'unit,
whereby my improved device; may be at-' tached to any type of loom without making any changes in its construction.
In the accompanying drawings, V Figure 1 1s a front view ofa well known form of shuttle box having my invention attached thereto.
' Fig. 2 is an :end view of the box shown in Fig. 1.
Fig. 3 isa sectional view along the line 3- 3, Fig. 1. I
Similar reference characters refer to similar parts in the different figures,
The invention is shown inconnection with a multiple typeshuttle boxof a well known construction which comprises superimposed raceways 1 and 2 for the travel of apair of shuttles 3 therein. Itis obvious, however, that my invention may be as well-applied to a shuttle'box adapted to rec'eiveany desired number of shuttles. The raceway f'or each shuttle" 3'is formed by the backwall- 4:
of the box and the horizontal partitions 5 between the -raceways,-' there being the usual Patented. May 3,1921.
Application filed January 2,1920. Serial-N01348985. 1
clearance between the shuttle 3' and the front wall 6 of the box. 1
Thefront wall 6'fprovides bearing lugs 7 for a shaft 8, upon which are pivotally mounted the swells or shuttle binders 9.
The binders 9 are forced into the shuttle box by springs 10, so that as the shuttles 3 move to the right er toward the closed endofthe A frame 13'is secured at its'ends to the p I top and bottom partitions'5 .of the box by means of set screws 14.- whichpermit the frame to be vvertically adjusted with respect:
to the box. The frame 13 is provided with notches 15 for the reception of the ends of the partitions 5, andwith substantially" semicircular depressions 16 for allowing free movement of the binders 9 therein? The 2 secured to t e ends 9!: the 5 Th? slide'within the openings 17 and a crossbar rods 19 are respectively provided at their ends with a threaded portion 21 having adjusting nuts 22 in engagementtherewith, and the lower rod of each slide is provided with a rack portion 23. The slides 18 are adapted to be normally maintained toward the back wall Lof the shuttle box by springs 24 which are secured to the front wall 6 beneath the binder springs 10. It is obvious that any other type of spring maybe employedto hold the slides in their outward position,such for example ascoil springs surrounding the rods 19. The movement of each slide under the influence. of the spring 24 is limited by the nuts 22. v I
.The frame 13 is'also provided with a plurality of openings 25 extending at right angles to the-openings 17 within which are located pinions 26 each in engagement w th the rack portion'23 of a slide. Each pinion 26 is provided with a shaft 27 which extends parallel to the raceways and is supported at its end in a bracket 28 secured to the partition 5-at the open end of the shuttle box. The. shaft 27 is provided with a clamping portion 29' extending at right angles thereto,
' closed end of the shuttle box and provided as best shown in Fig. 3.
From the foregoing it is apparent .that
when ashuttle 3 .is' driven home in the box by reaching the end of itsmovementto the right the tapered end portion 30 thereof will engage the crossbar 20 of a slide 18 and force it outwardly against the action of the spring 24. I As this occurs. the movement of the rackportion 23 turns the corresponding pinion 26 with its shaft 27,- whereupon the clamping portion 29 moves upwardly and clamps the thread 31 extending from the end of the shuttle 3 against the front wall 6- of the shuttle box. In this Way the thread 31' is prevented from sagging downwardly or from being pulled out of place by the beat- .ing action of the fabric on the loom.
It isapparent that the several slides and shafts can be assembled on'the, frame 13 and then applied to the shuttle box as a complete. unit it only being necessary to adjust the position of the frame bymeans: of the set screws 14, and to attach the ends of the shafts 27 by means of the brackets 28. This may be done, of course, without in anyway disturbing the parts, of the shuttle box. After the frame has been attached to the box, the movement of the slides 18 can be.
adjusted tocorrespond to the size of the shuttle and thewidth' of-the shuttle box by means of the adjusting nuts22. The provision of parallel bearing members on the slide insures that it will always move freely without binding, due' to the fact that the force of theimpact of the shuttle is transmitted equally to the rods 19 by the crossbar 20.
l/Vhile I have shown my invention in its simplest and preferred form, it is not so limited, but is susceptible of various modifications within the scope of the appended claims. a a
' 1. In a loom, a frame'mounted at the closed end of the shuttle box and provided w-ith means for clamping the weft thread at the open end of the shuttle box.
2. Ina loom, a frame detachably secured with a slide normally extending into the path of movement of the shuttle and con nected to a weft thread clamping device at the openend of the shuttle box.
5. In a loom, a frame mounted at the closed end of the shuttle box and provided with a slide connected to a weft thread clamping device, and means for adjusting the position of the slide in the shuttle box.
6. Ina loom, a frame mounted at the closed end of the shuttlebox and provided with a slide connected to a weft thread clamping device, the said slide comprising parallel members, movable within the frame, anda cross member joining the movable members and adapted to be struck by the shuttle.
7'. In a loom, a frame mounted at the closed .endof the shuttle box' and provided with an operating device yieldably held in the path of movement of the shuttle, the
said device comprising members slidably mounted on the frame and joined by a cross member for receiving the impact of theshuttle as it enters the closed. end of the box.
