application filed July M, 1919. Serial No. 310,553.

To all whom it may concern:

Be it known that we, MICHEL NADEAU and ADoLeHE Boovmn, citizens of the United States, residing at Auburn and, Lewlston, respectively, in the county of Androscoggin, State of Mame, have invented a new and useful Check for Looms, of which the following is a specification.

Thls invention relates to checks f r looms one of its objects being to provide a simple and compact device constituting an etficlent check for the shuttle of a box loom and which can be applied readily to the back 0 the lay and under the shuttle box.

Another object is to provide a device of this character which can be used on any standard form of single box loom.

With the foregoing and other-objects in View, which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the claims.

In the accompanying drawings. the preferred form of the invention has been shown.

In said drawings- Figure l is an elevation of the device in position.

Fig. 2 is a horizontal section through the check on the line 22, Fig. 3.

Fig. 3 is a central vertical transverse section through the device, on the line 3-3,

Fig 2.

ig. 4 is a plan View of the friction shoe.

Fig. 5 is a side view thereof.

Referring to the figures by character of reference, A designates a portion of the lay of a loom and B designates a shuttle box. The check constituting the present invention is adapted to be secured to the back of the lay and under the shuttle box and includes an attaching plate 1 having a slot 2 for the reception of an attaching bolt. 3 extend from the plate 1 and are designed to extend under the lay, thus to hold the plate against rotation about the bolt in the slot 2. Extending along the lower edge of the plate 1 at right angles thereto and under the lay is a flange 4: provided in its free'longitudinal edge with spaced dovetail recesses 5 adapted to receive the dovetailed. lower ends of guide fingers 6 extendl'ng downwardly from a top plate 7 on which are formed reinforcing rlbs or webs 8. s The fingers are adapted to be inserted downwardly into the recesses 5 after which the top plate 7 and webs 8 are secured to the plate 1 by screws 9 or the like inserted through the plate. The plate 1 is preferably formed wlth upper and lower openings 10 separated by a bar 11 and a lug 12 extends laterally from the central portion of this bar and under the top plate 7.

Extending through-the center portion of the flange 4 is an adjusting screw 13 preferably provided with a lock nut 14. and bear 1ng downwardly upon this screw is a bowed spring 15 the ends of which are slightly downturned and which spring forms a friction shoe. The sides of the spring are extended laterally to form shoulders 16 which project between the fingers 6 and under the bar 11, thereby to hold the spring against longitudinal displacement.

which the lug 12 projects and the walls of the recess are covered with leather or other cushioning material as shown at 19. Oppoe sitely extended U-shaped arms project from the ends of the slide, as shown at 20 and the ends of the arms lap andinterfit, as at 21, and are held together by a bolt- 22. A picker arm is adapted to work within the loop-formed by the arms 20 and'when it strikes either end portion of the loop it will shift the slide 17 longitudinally until (Ime egd of the recess 18' comes against the ug 1 the pounding and the spring shoe 1'5 acts to retard the movement of the slide and, consequently, the picker arm.

By employing the lapping connected arms 20 the device can be applied readily to the picker arm and lay. The screw 13 allows the tension of the spring shoe to be adjusted as desired. 7 y

What is claimed is r--- 1. A check attachment for single box looms, including an attaching plate, a flange thereon, a lug upon the plate and overhanging the flange, a top plate detachably fastened tothe attaching plate, guide fingers The cushioning strip 19 reduces depending from the top plate andconnected to the flange, a-spring shoe adjustably supported above the flange, a slide mounted on the shoe and frictionally engaging the top plate, said slide having a recess into which the lug extends, and a loop carried by the slide for the reception of a picker arm.

2. A check attachment for single box looms including an attaching plate havin a flange, a lug on the plate, a top plate etachably connected to the attaching plate and flange, an adjustably supported spring shoe, a slide on the shoe and frictionally
