with the stick and carrier what is in efiect a unitary assembly readily attachable to any stand}; ard picker-stick carrier and of such construc;
tion as to withstand the wear and tear imposed- The invention is herein shown applied to a.
box-loom but it may be applied, as will parent, to a plain loom. In the drawing, Fig. 1 shows the carrier and my device in plan and the picker-stick in section;
Fig. 2 is a plan of said device on a larger scale; Fig. 3 is a front elevation of said device, with a part of the carrier appearing in broken lines; and
Fig. 4 shows the carrier, picker-stick and said device in front elevation. On the horizontal rock-shaft I, journaled in the frame a, is made fast, as by s'etscrews 2, the usual carrier 3 in whose terminal 30, the picker,- stick 4 is pivoted to move in an upright plane extending lengthwise of the rock-shaft. Said carrier being here adapted for a box-loom hav'-'- ing shiftable bo'xes, it is formed with a rearward bend as seen in plan and as usual and, upstand; ing from such bend, with a guiding portion 3b for guiding the box-rod 5. The pivot for the picker-stick is formed by a pin or bolt 6 which penetrates the terminal 30. and is formed with a collar Ba and has a nut I for'clamping it to the carrier, 8 being the usual cotter-pin to retain the picker-stick on the bolt. v
According to this invention means is provided for checking the shuttle-impelling movement tr and thereupon retracting the picker-stick (or stick) 4 as follows:
A bracket is made fast to the carrier and in the present instance includes the following parts: 9 is an L-shaped part or angle-iron to one arm be ap a projection, as Ila (Fig. 4).

Projecting from that side of the latter arm which adjoins the stick is a pair of spaced guide-pins I2, preferably fixed to said arm in any way, as by being welded thereto.
0n the pins of the thus-formed bracket and arranged in the path of movement of the pickerstick is an elastic bufi'er means formed as fol lows: A U-shaped bufier I3, formed of some tough, preferably fibrous material, as raw-hide,
is slidable on the pins I2, its extremities projecting toward said arm of the bracket and penetrated by the pins. Between its extremities the buffer has a stud l3a projecting toward said arm. Bearing against that face of said arm which adjoins the buffer is a yielding somewhat elastic pad I4, as of leather, penetrated by the pins. And between the pad and buffer is a helical spring I5 into which stud I3a projects and which normally tends to maintain the buffer at the limit provided by the heads of the pins I2.
In this example the device comprising the bracket and the elastic stick-control or buffer means is so related to the terminal 3a of the carrier that said means is at an elevation below that of the picker-stick pivot whereby the part of the stick below such pivot will at its outer side contact said means, which is here outward of the stick; but, obviously, the formation of the carrier being such that said device could be accommodated, the latter could be positioned, in inverted state, at an elevation above that of the pivot,
in which case the stick would contact said means 7 stroke of'the stick its movement is at first yieldingly opposed by said parts I 3l 5 of said means of which is rigidly fixed, as by a bolt or rivet 66 but finally it is more positively but still yieldingly opposed by the parts i3-i 4. Thereupon the parts l3-i5 again come into effect to retract the stick.
The construction is not only such that the checking and retracting functions are performed by what is a unitary assembly readily attachable to any standard loom but the arrangement and disposition of the parts of said assembly are such imposed on them.
It is noted that the picker-stick pivoting bolt,-
5 itself pmvides the means Securmg the lbracket betweenlthe latter arm and the pickerbracket to the carrier. Further, that that sur face of the arm of the bracket beyond which pro- .iection Ha extends provides a ledge 9a contacting the under edge of the carrier terminal 3a'; whereby to prevent the bracket from shifting Having thus fully described my invention, what I claim is:
1. In combination, with the picker-stick carrier of a loom and apicker-stick pivoted therein to move in an upright plane, means to check the shuttle-impelling movement of and thereupon retract the picker-stick comprising a bracket L-shaped in plan and having one arm thereof afiixed to the carrier and the other projecting,
laterally of the picker-stick, through said plane and in a horizontal plane close to but removed from the horizontalplane of the picker-stick pivot, and elastic buffer means supported by the stick. e,
2. Incombination, with the picker-stick car- I rier ot a loom having a projecting pivot-forming clamping device and with a picker-stick pivoted on saiddevice, a bracket penetrated and clamped to the carrier by said device, and elastic means, carried by'the bracket, to check the shutt1e impelling movement of and thereupon retract the picker-stick. v
