\ sHu'r'rLE-Box MOTION FOR Looms.

Application med August 27, 1925, Serial No. 52,757,`and in France December 5, 1924.`

This invention relates to shuttle box motions ot looms of the `kind in which toothed sectors carried by a rotatably mounted plate or disc are adapted to engage with freely rotatable satellite pinions, whereby each pinion is periodically given a-lialf rotation at each passage ot' a toothed sector in engagement therewith, the pinions being adapted to be respectively clutched, under the control of the card `mechanism of the loom, to corresponding rotatable members mounted upon the same axes as the satellite pinions Vand provided with `cranks or crank pins by which` movement of the rotatable membersis communicated to the shuttle boxes through levermechanism, one halt rotation of the respective pinions serv in to effect `the rise of the shuttle boxes, w rile the succeedinghalf rotation serves to effect the fall of the boxes. By suitable Operation ot the clutches by which the satel. lite pinions are connected to the respective rotatable members, any desired position f` of the shuttle boxes may be obtained.

The invention specially relates to shuttle box looms ot the kind referred to, such as described; inthe speciication ot the copending application No. 16,459 dated 18th March, 1925, Patent No. 1,617,143, and in which four satellite pinions disposed t-wo and two in different planes areemployed,`

whereby any desired position lot the shuttle boxes from one to twelve ,may be obtained, the rotatable members being connected to the shuttle boxes by means ot lever and rack and pinion mechanism so arranged that a half rotation of each ot two ot the satellite pinions'causes the shuttleboxes to rise or Atall to an extent of four boxes, while the third and fourth satellite pinions cause the rise or fall of the boxesto an extent of two boxes and one box respectively.

In such mechanism each satellite pinion isf clutched to the respective rotatable member by means of a pin mounted within a hole in the rotatablemember or a part integrally secured thereto, which pin is adapted alternatively ltoengage within one oftwo diametrically disposed holes inthe satellite pinion, the pin being pressed into the respective hole by means "of an Operating member Aunder the control of the card mechfV anistn. y y

VThe present invention 4has among its objects to provide an improved construction of the mechanism by which the clutching `spindle or shaft b by means o of the satellite pinions to the respective rotatable members is effected. A

According to the present invention in shuttle boxmotions of the kind referred to the means' by which each satellite pinion 1s alternatively clutched under the contro] ofthe card mechanism of the loom to the respective rotatable member, comprises a pin mounted` to revolve with and about the axis of the rotatable member, and adapted to engage alternatively with one of two corresponding diametrically disposed holes in the satellite pinion, a pair of independentV operating members disposed laterally of the axis of the satellite pinion in determined positions, such that `they may operate to press the pin into one of the two diametrically disposed holes in the satellite pinion, whereby-one operating member serves to cffect the rise of the shuttle boxes and the other to effect the fall of the schuttle boxes, and-means connecting each of the said op` erat-ing members to the card mechanism of the loom.

The invention is hereinafter described by way of example with reference to the accompanying diagrammatic drawing, in which: y

Fig. 1 is a front sectional elevation on the line E-F Figurel 2 showing one of the four satellite pinions.

1Fig.`2 is a horizontal section on the line Av-B, Figure l. i i

Fig. 3 is a sectional side elevation on the line C-f-D Figure 2, and

Fig. 4 is a rear view corresponding to Figure 1. I

The pinion o is provided `freely rotatable and withv `two t diametrically disposed lholes c c1 in which holes a pin (l carried in a part f, keyed or otherwise integrally secured to a sleeve or member n rotatably mounted upon the spindle or'shatt ,`may alternatively be Aengaged."` The pin (l is provided with a re* turn spring c mounted within `a recess provided lor the purpose within the `part f.

The parts f, g and/1, `lorm kan integral uniti `which rotatable upon the spindle or shaft b and is maintained in fposition on the the ring gand the disc h and at its `forward [extremity by the [lange m ontbegspindle .0r shaft` engaging within corresponding recesses inthe sleeve or member n. The sleeveor member a lsatits outer extremity providedfwth a laterally extending flange or part nl upon fai ico

-and the part j".

the face et which a crank n2 or the equivalent, by which motion is transmitted t'o the shuttle boxes, isniounled. The pinion (i is rotatably mounted upon the sleeve and .is disposed between the laterally extending tlange or part nl ot the sleeve or member n The pinion o is rot-ated intermittently, but always in the same direction and through halt a revolution on each movement. lt will be understood that, the c ank 'a2 being disposethtor example, in the uppermost position, the pin cl is disposed, for example, at 90o to one side. lt' the pinv be engaged with the pinion i in one ot' the holes c, c1, the pinion will carry the crank n2 into the lowermost position thus raising the shuttlc boxes or vice versa. The pin (Z will now be d. Jposed inthe opposite lateral position tarding eliect on the rotatable and when it is next engaged with the pinion c', the latter will carry the crank fr again to the uppermost position thus lowering the shuttle bof; or vice versa.

llwo cpc i ing arms fz', y' are pivotally mounted upon the spindle lr, and are integrally provided with the respective arms il, jl respectively Jiorming bell crank levers, and the respective arms 1, il are each connected at their ends to flexible men'ibers or cables Z actuated by the card mechanism ot the loom.

TWhen for example the upward movement thus clutched to the rotatable sleeve or mcmber it.

A spring pressed pin a: nnmnted within a recess in a stationary part of the mechanism is adapted to press against the rear 'tace ot the disc 7L and thus to exercise a slight resleeve or member n. By such means while the pinion is being' rotated the pin (Z engaging within the hole c1 in the pinion a is subjected to a slight shearing action suliieicnt to maintain it within the hole c1 until the rotation ot the pinion ceases whereupon the pin (l is withdrawn trom the hole c1 by means ot' the spring e. By such means the half rotation ot the pinion is transmitted to the rotatable sleeve or member n and the shuttle boxes are caused te move into the desired position.

Then the fall of the boxes is to be elected, the operating arm 1 having been allowed to return to the inoperative position so that the pinion c turns freely, the arm jis actuated by the respective lexible member or cable Z to torce the pin Z again into the hole c1 in the pinion a causing the descent ot the boxes.
