SPECIFICATION forming part of LettersAPatent No. 322,140, dated July 14, 1885. Applicationmed May es, resi. (No` model.)

l To all whom it may concern:

Be it known that I, WILLIAM R. THRASII, a citizen of the United States, residing at Selma, in the county of Dallas and State of Alabama, have invented a new and useful Improvement in Loom-Pickers, of which the following is'ga specification.

My invention relates to pickers for looms; and it consists of the picker hereinafter fully described, wherein the leather or rawhide iilling or thrust material is very securely held in place and prevented from losing its proper form by being bulged outV or torn asunder from constant and violent contact of the shuttle therewith. a

In theaccompanying drawings, Figure l is a perspective view ot' the upper end of a picker-staiic having applied thereto a picker embodying my invent-ion. Fig. 2 is a'central longitudinal section ofthe same, the clampscrew and picker-staffe being in elevation. Fig. 3 is a horizontal transverse section in the line of the clamp-screw, the clampfscrew being in elevation; and Fig. 4 is a view showing a section of the picker on the line m of Fig. 2.

A @represents a pickerstaff to the upper portion of which the picker B B is fastened. This picker consists of a pad composed of a number of layers, b, of hard leather or rawhide and a nieta-l housing, B This metal housing B has solid parallel sides b', a solid back, b2, with a set-screw, b3, and a front having an opening in it between two connectingplates bt b5, which are respectively at the upper and lower extremities of the housing B. The upper and lower sides of the housing are open. The rear portion of the passage through the housing is of the same width as the thick`- ness of the picker-staff", and this inner width is continued in thel rear portion of the housing down to its lower extremity, for the purpose of receiving and holding the pickerstaff. The larger `portion of' thehousing B', forming its front part, is of greater width than the picker-staff in order to receive the material forming the striking-portion of the picker, this portion of thelhousing B being provided with inner rear vertical shoulders,

be, and inner upper shoulders, bl. The upper part of this front portion of the housing is reduced to the width of the picker-staff by means of the two horizontal shoulders bl, and the' layers forming the striking portion of the picker are formed withshoulders bs, and shaped to fit the passage formed in said front portion ofthe housing, and to bear against the shoulders b6 and bl. By this construction, in conjunction with the pickerstaff, the united layers of leather or other material are prevented from being -moved either upward or backward by the thrusts of the end of the shuttle. y Y

When the pickerstaii` and leather pad B are properly inserted in to the housing B', the set-screw b3 ,is set up for the purpose of clamping them together. By this operation of the set-screw the picker-staffis forced against' the strips of leather b, vand the latter are forced against the front plates, vb4 b5, and thus held firmly in place. The side walls, b, prevent the leather from being spread s idewise or torn or crushed so as to divide lengthwise, while the shoulders b6 b7 prevent the leather from spreading'and being torn or crushed so as to burst crosswse. With my invention an improved picker,which cannot readily have its form changed or be wornv out rapidly, is produced at slight expense, it being practicable to cast the housing of the form described in one piece and to cut the leathers in the form shown byfa die.

`WhatI claim as my invention isl. The combination of the picker material B, having the shoulders ba, with the housing B., open at top and bottom, and having closed side walls, partly open front Wall, a perforated rear wall, and vertical shoulders bs, and horizout-al shoulders bl, and the clamp-screw b3, substantially as and for the purpose described.

2. The combination of the picker material B, having shoulders be, with the clamping-housing B', having closed side walls and shoulders b6 bl, substantially as described.
