PICKER-CHECK FOR LOOMS.

SIECIFICATION forming part of Letters Patent No. 415,753, dated November 26, 1889i.

Application tiled January 23, 1889. Serial No. 297,278. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT WHrrEHoUsE, of the city, county, and State of New York, have invented a new and useful Picker-Check for Looms, of which the following is a full,

clear, and exact description.

My invention relates to an improved picker check or bunter for looms, and has for its object to provide an elastic cushion capable of read-y attachment to and detachment from a loom, whereby the shock or concussion usually sustained by the contact of the shutt-le with the picker will be largely reduced and the shuttle-binder need not be so tightly adjusted as heretofore.

The invention consists in a picker check or bunter having' a flexible cushion face, and in the novel construction of the said bunter, as will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying' drawings, forming a part of this specification, in which similar gures of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section through t-he projecting portion of the frame-work and the shuttle-box of a loom, illustrating the position of the bunterY in the loom, which position is immediately to the rear of the picker. Fig. 2 is a side elevation of the bunter, partially broken away. Fig. 3 is a bottom view of the saine; and Fig. 4 is a face view of the said bunter, showing the cushion carried to one side.

The bunter is adapted especially to replace the one at present in almost universal use, which latter consists simply of pieces ot cloth rag bunched together and inserted in the pocket or projecting portion of the loom-frame in front of the picker 11, in which position my improved picker check or bunter is illustrated in Fig. 1.

The improved bunter consists of a frame or body 12, preferably of greater length than width, adapted in contour to the contour of the frame-pocket at the rear of the picker of the loom. The body-frame 12 is usually constructed with a depression 13 in the inner face, at or near the center, which depression, when the bunt-er is in proper position,is adapted to be in horizontal alignment with the travel ot` the picker. In the inner face of the bodyframe, at each side of the central depression, a recess 14 is formed, into which recesses a spring 16 is severallyv inserted, and a strip of leather 17 or other equivalent tiexible material of suitable width is pivotally attached to the ends of the body-frame and drawn tightly over the inner face of the samein contact with the outer ends of the springs 16.

In Fig. 3 of the drawings, which is a bottom View of the bunter, ashoulder 18 is shown as centrally formed at one side ot the bodyframe, which shoulder -is not absolutely necessary in the formation of said frame, being device into one form of loom.

l desire it to be distinctly understood that the body-frame may be constructed either of Wood, of iron, or of other suitable material,

and that the leather strip 17, which acts as a cushion, may be replaced by a strip of canvas, rubber, or other like flexible material, and that the springs may be Otherwise attached to the body-frame; or other forms of spring may be employed Without departing from the spirit of the invention. The springs 16, should they become weakened and uni-lt for use, may be quickly removed by carrying the cushion 17 over to one side of the frame, as sho'wn in Fig. 1i, the said cushion being pivoted for that purpose, .whereupon the Vouter ends of the springs' will be uncovered, and they may be readily detached and replaced by others. The cushion 17 is drawn When not in use or when in operation.

- Vhen my improved bunter is employed in connection with a loom, it permits the weaver to use shuttles of differing weights and sizes, (which now cannot be done Without a readj ustment ot the shuttle-binden) as the shuttlc-binder will not have to be adjusted so tightly that any difference in the size of the shuttle can affect it. lVith the old form of bunter, however, a great pressure must be brought to bear upon the shuttles by the binders, so that the shuttles have to be of equal size in order to Work properly.

adapted only to facilitate the tit-ting of the.

suficiently tight over the springs 16 as to prevent it from Working to one side eitherl IOO 'Although I have illustrated my invention as applied to a particular form of loom, I Wish it to be understood that it is applicable t0 any form of loom.

Having thus described my invention, I claim as new and desire to secure byLetters Patent- 1. A picker-bunter for looms, consisting' of a body and a spring supported cushion,

' formed of leather or its stated equivalent,

covering' one face of the-said body, substantially as shown and described. l

2. As an improved article of manufacture, a picker-bunter for looms, consisting of a .body and a pivoted spring-supported cushion covering one face of the said body, as and for the purpose speciied.

3. As an improved article of manufacture, a picker-bunter for looms, consisting of a body having a cavity in one face, a flexible cushion extending from end to end of the body over the cavity therein, and springs between the adjacent faces of the cushion and body at opposite sides of the said cavity, substantially as shown and described.

4. As an improved article of manufact-ure, a picker-bunter forlooms, consisting of a body, a cushion pivoted to the said body at. the ends and extending over one face, and detachable springs held in contact with the opposed faces of the cushion and the body, substantially as shown and described, and for the purpose specified.
