LOOM PICKER ROD SPINDLE SUPPORT Filed Jan. 15, 1929 e/liar Patented June 24, 1930 UNITED STATES PATENT OFFICE KENNETH J'. UNWIN, 0F WORCESTER, MASSACHTTSETTSQASSIGNORS TO CROMPTON & KNOWLES'LOOM WORKS, OF VIORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS LOOM PICKER--ZROD 'SPIND'LE SUPPORT Application filed January 15, 1929. Serial No. 332,638.

This invention relates to picker rod mountings for looms and it is the general object of the invention to provide a mounting capable of continuous adjustment throughout a relatively wide range whereby the picker spindle may be moved both vertically and horizontally.

In the usual form of weft replenishing multicolor looms the shuttle is propelled by a picker which moves along a picker spindle located behind the shuttle box. This construction is also employed on the drop box end of fancy looms. It is desirable to be able to vary the position of the outer end of the picker spindle so that the same can be moved either toward or from the box back or vertically either toward or away from the boxplate on which the shuttle normally rests when boxed. It is an important object of my present invention to effect this ad justment by a simple means employing threaded members which extend into the lay end of the loom and support a third threaded member which can be adjusted vertically so as to vary the position of the picker spindle with respect to the box plate.

With these and other objects in View which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

In the accompanying drawings wherein a convenient embodiment of my invention is set forth, s

Fig. 1 is a top plan view of a lay end hav ing my invention applied thereto, parts being removed for the sake of clearness,

Fig. 2 is a rear elevation taken in the direction of arrow 2, Fig. 1, and

Fig. 3 is an enlarged vertical section taken on line 3-3 of Fig. 2, certain parts being in elevation.

Referring particularly to Figs. 1 and 2, I have shown a lay sword 10 on which is mounted a lay end 11 provided with a boss 12; Said boss receives the inner threaded end 13 of a picker spindle P. The lay end has provision as at 14; for receiving the lay driving connectors not shown.

The lay sword mounts or supports a lay 15 carrying the usual reed 16 along which the shuttle S normally -moves. There is mounted on the outer end of the lay end a stand 17 which is more particularly shown in Fig. 8, said stand having a relatively thin web 18 at the rear portion thereof.v

The shuttle 100x20 has a rear wall 21 which is substantially in alignment with the reed 16. Said shuttle box is provided with a tongue 22 which moves in a guide 23 fixed with respect to the lay. A second tongue 24 slides in a second guide 25 also fixed with respect to the layand located at the. outer end thereof. The shuttle box 20 moves vertically with respect to its guides by mechanism not shown but well understood.

A picker 26 is engaged by the upper end of the picker stick 27 which is actuated by mechanism not shown when the lay has reached substantially its mid position on the rear stroke thereof. The picker stick moves the picker along the spindle P and by reason of engagement between shuttle S and the picker the shuttle is propelled along the lay l5 and reed 16. The matter thus far described forms no part of my present invention, being of the usual construction.

In carrying my, invention into effect I provide means for adjusting the outer end of the picker spindle P by employing a pair of threaded

eyes

30 and 31 which are located, respectively, above and below the picker spindle. Each eye has a threaded end 32 which extends through a clear hole 33 formed in the web 18 of the casting 17 as clearly shown in Fig. 3. Each eye is provided with a forward check nut 34 on the front of the web 18 and a second check nut 35 at the rear of said web, said check nuts holding the eye in fixed adjusted position with respect to the wall 21 of the shuttlebox.

The vertical spindle supporting element 36 hasv a bore 37 through the portion to receive the outer end of the spindle P and said.

support has oppositely extended

threaded ends

38 and 39 which cooperate respectively with the

eyemembers

30 and 31. The

eyes

30 and 31 are provided with openings 10 which may be tapped toreceive the threads of the su porting member. Check nuts 42 are provi ed to justed position. The openings 40 may be clear holes in which case there would be rovided a set of two check nuts, one on each side of the

eye member

30 and 31.

In assembling the construction set forth herein the

eyes

30 and 31 will be connected to the support 36 substantially as shown in Fig. l but with the forward check nuts 34 not in place. The eyes are then inserted through the clear openings 33 after which the check nuts 34 may be applied to hold said eye members in fixed position with respect to web 18 and therefore the box back 21. Adjustment of the outer end of the spindle toward and away from the box back and reed may be eii'ected by changing the

lock nuts

34 and 35. If it is desired to vary the vertical position of the spindle P thenuts 42 may be adjusted so as to vary the ition of the opening 37 of the supporting member 36 either to raise or lower the picker spindle as desired. Vhen in pro r position the nuts 42 may be tighten to hold the spindle supporting memher in proper position.

From the foregoing it will be seen that I have provided a simple means for effecting continuous adjustment through out a rather wide range both for vertical and horizontal adjustment of the picker spindle and means are provided for holding the adjustment in any position.

Having thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a loom la having a picker spindle the inner end 0 which is supported in fixed position with respect to the lay, a supporting member for the outer end of the picker spindle having oppositely extending threaded portions, and a pair of threaded eye members, one for each threaded portion of the supporting member, said e e members extending throu li a portion of the lay and being capable 0 assuming a plurality of horizontal positions with respect to the lay.

2. In a loom lay having a picker spindle the inner end of which is supported in fixed position with respect to the lay, a spindle supporting member having oppositely exten ing threaded portions, an up er eye member to receive one of the threat (1 portions, said upper member being received a part of the lay and capable of assuming a plurality of horizontal positions with respect to the lay, and a lower eye member to receive the other threaded portion of the supporting member, said lower eye also hold the member 36 1n adbein received by a part of the lay and capa le of assuming a plurality of horizontal positions with respect to the lay.

3. In a loom lay having a picker spindle the inner end of which is supported in fixed position with res t to the lay, a pair of spaced threaded su antially horizontal members extending into and supported by a part of the lay and capable of assumi a plurality of horizontal positions with respect to the lay, a supporting element for the spindle, and threaded connections between the supporting element and the members, whereby said supporting element is capable of assuming a plurality of vertical positions with respect to said members.

4. In a loom lay having a picker spindle the inner end of which is supported in fixed position with respect to the lay, a pair of spaced eye members having threaded portions to be received by a part of the lay, a spindle supporting element having oppositely extending threaded ends, one end to be received by each eye member, said eye members being capable of assuming a plurality of horizontal positions with respect to the lay and the supporting element being capable of assuming a plurality of vertical positions with respect to the eye members.

5. In a loom la having a picker spindle the inner end 0 which is supported in fixed position with respect to the lay, said lay having a pair of spaced substantially parallel openings therethrough, a pair of threaded members, one for each opening, a pair of check nuts lying on o posite sides of the opening and each threa member, an eye for each threaded member, the eyes being substantially in vertical alignment, a spindle supporting element to receive the outer end of the spindle, said element having oppositely extending threaded ends which pass through the eyes, and a pair of check nuts for the supporting element, one for each eye, whereby the vertical position of the spindle supporting element may be varied with respect to the eye members.

In testimony whereof I have hereunto aflixed my signature.
