To all whom it may concern: 4

l Be it known that I, WILLIAM H. AYER, a citizen of the United States -'of America, residing at Claremont, in thecounty of Sullivan and State of New Hampshire, have invented new and useful Improvements in Shuttlndihecks for Looms, of. which the following is a specification.

This invention relates to shuttle checks for looms, and articularly for looms of that class wherein t 1e shuttle checking is carried out bythe action of the check on the picker stick. The invention is applicable in this connection to looms in which the picker is connected with the picker stick or in which the .icker runs on a picker rod.

T e object of the invention is to provide a check of simple construction which will effectually cushion the impact of the shuttle on the picker and hold the picker stick, and consequently the picker and shuttle, from rebounding or moving forward, thereby obviating the necessity of using heavy friction on the shuttle binder and preventing the loss of shuttle throwing power which occurs when the shuttle is permitted to have a forward or rebounding movement.

Another object is to provide a check which will hold the picker stick directly in line with the shuttle point and which is applicable to the lays of different types of looms and is adjustable to properly position it for action thereon.

In the accompanying drawings,Figure 1 is a view in side elevation of one end of a lay having my improved shuttle check applied thereto and showing the picker stick in dotted lines. Fig. 2 is a bottom plan view of the 3 is a perspective view of one form of chec Fig.

Fig. 5 is a horizontal section through a modified form of bracket.

' portion 5 provided with forwardly extending wings or cheek plates 6. These wings or cheek plates extend a short distance in par- Referring now more particularly to the drawings, the" numeral 1 denotes one of the end portions of a lay, the same being provided with the slotted guideway or race 2, in which the upper end of the-picker stick 3 fits and plays.

The check 4 is formed of sprin metal and comprises a narrow vertical b0 y plate or allel relation from the body dportion 5 and are thence outwardly curve or flared, as

ing fitted within the other.

- indicated at 7, to form a mouth or entrance space to the check which radually decreases in width toward the parallel portions.

In the form of the invention shown in Fig. 3, the check 4 is composed of a single piece of spring metal bent into the described form, whereasein-iiEig. 2 the checknis illustrated as being composed of two parts or inner and outer members 4 and 4 having the construction set forth, one of said members be- If desired, however, the check may be constructed of a single piece of metal having wings or cheek pieces of double length, 'with their; outer alves folded inwardly to give a double ply formation and to, correspondingly stiffen and strengthen the wings. or cheek pieces. In either construction a ply or layer of leather 8, which may simply cover the inner faces of the wings, or correspond in contour to and extend around the inner surface of the check, may be used in order to secure the desired frictional pressure against the picker stick and prevent undue wear thereon'and on the wings of the check. The check is supported below the end of the lay by suitable s'upporting means, that shown 1n the present instance comprising a bracket or hanger 9 consisting of a metallic strap bent or folded centrally upon itself to provide parallel arms 1-0 and 11 connected at their upper ends by a head or union piece 12, both arms being formed with series of aliningperforations 13. The bracket or hanger as thus constructed forms a saddle or stirrup which is hung u on the outer end of the lay 1 with its hea or union piece 12 resting upon the'narrow wall between the end of the lay and the outer end of the race 2, and the arms 10 and 11 respectively projecting downwardly through the race and against the outer end surface of the lay and projecting some distance below the same. The arms of the bracket are connected to each other by bolts 14 passing through the alining perforations 13 and carrying clamping nuts 15, two or more of the upper bolts of the series also extending through the outer end of the lay and the body portions and securing the bracket thereto, while the depending ends of the arms of the bracket bear against the inner and outer surfaces of the body portion or portions of the check and clampthe same to the bracket. The leather layer 8 may be fastened in any referred manner to the check, but as shown 1n the present instance is fastened at its ends to the ends of the wings by rivets 16 passing through perforations 17 formed in said wings, the rivets also, in the construction shown in Fig. 2, passing through the plies of 5 the two-part check and holding the same rigidly connected.

It will be observed that the check is free when the bolts below the lay are loosened to be adjusted vertically relative to the lay to arrange it closer to or further from the same to suit different conditions of service, and that by tightening the bolts it will be firmly and securely clamped in adjusted position.

I In the operation of the device the picker atick 3 in its outward movement under the impact of the shuttle on the picker passes between the divergent ends of the cheek pieces or wings 6 and comes in contact with the leather ply S which exerts frictional pressure thereon to retard its movement until when the stick enters the space between the parallel portions of the cheek plates, 1ts motlon will be entirely arrested. Bythis means the picker stick will be brought gradually to a stop without shock. or jar, and the impact of the shuttle properly cushioned. When the stick contacts with the check at the point where the wings begin to flare outwardly,\-the latter will spread a art to a slight-extent under the pressure of the stick and then, upon the passage of the stick into the space between the parallel portions of the wings, will, by their spring action, bear against the stick and exert suflicient frictional pressure there- 25 on to prevent the stick from rebounding or moving forward. By this means the impact of the shuttle on the picker will be effectually cushioned and the parts prevented from having the usual rebound or forward movement, thereb obviating the necessity of using heavy ictionon the shuttle binder and preventing the loss of shuttle throwing power which occurs when the shuttle is permitted to have such rebounding movement. The picker stick will be held in the check until it is positivel actuated in the reverse direction by the 00m mechanism, as will be readily understood.

Projecting downward from the lay on opposite sides of the race 2 are pins 18 which ear against the innerfaces of the outer ends of the wings or cheek pieces 6 and hold the same s read the desired distance a art and limit t eir inward movement, so t at they will not bear with undue pressureupon'the picker stick. The wings slide in contact with these pins so that the cheek may be adisted vertically without interference thereom. The construction of hanger or means for supporting the check from the lay may be varied to suit variations in the construction of the lays of different machines of the type referred to. For instance, in some makes of 015 machines, the inner arm of the hanger bracket cannot be extended downward through the lay. The construction in such cases may be varied by simply cutting away the upper part of the arm 10 from the head 12 downward a distance equivalent to the vertical thickness of the end of the lay, leaving the lower portion of said arm 10 free to act as an independent clampin jaw to clamp the check against the arm 11 below the lay, as will be readily understood. Other changes, such as clearly fall within the spirit and scope of the invention, ma also be made to suit different conditions 0' service, without I departing from the spirit of the invention or sacrificing any of the advantages thereof.

' In the construction shown in Fi 5 the inner or forward arm 10 of the brac ket is of less width where it is engaged by the body 'portion of the check than the outer or rear arm 11, and the rear surface of said arm 10 is convexed' or rounded, while the body ortion 5' is correspondingly shaped to ear against the same and extends laterally therebeyond. This form of the bodyportion 5 allows the wings of the check to have a greater range of outward movement. Set screws 19 are arranged on the arm 11' to impinge against the rear surfaceof the body portion on op osite sides of the center thereof, whereby t e extent of spreading movement of the wings may be regulated, and check nuts 20 are provided upon the screws to lock them in adjusted position. This construction secures a wider range of cushioning movement of the wings.

Having thus described the invention, what is claimed as new, is
