SHUTTLE-CHECK.
Specification of Letters Patent.
Patented 0015.8, 191s.
7 Application filed March 16, 1918. Serial No.'222,801.
To all whom it may concern:
Beit known that we, GEORGE W. ROBERT- SON and CHARLES C. BOLEN, citizens of the United States, residing at Danville, in the county of Pittsylvania and State of Virginia, have invented a new and useful Shuttie-Check, of which the following is a specification. i
This invention relates to animprovement in devices for checking'the'fiight of a shuttle in a loom and for thereafter holding the shuttle in correct position in the shuttle box.
It is the general object of our invention to provide an improved shuttle check for the purpose defined which shall be of simle and durable construction and which shall be highly efficient in use.
Our improved check combines the advantages of many complicated structures heretofore used, while at the same time it comprises only a single moving part.
Our invention further relates to arrangements and combinations of parts hereinafter described and more particularly pointed out in the appended claims.
A preferred form of our invention is shown in the drawings, in which Figure 1 is a plan view of one end of a lay with our improved shutle check mounted thereon, and
Fig. 2 is a front elevation of the parts shown in Fig. 1.
Referring to the drawings, we have shown a lay end 10, a fixed box plate 11, a shuttle 12, and a picker 13, all of the usual construction. Our improved shuttle check la is formed from a single piece of resilient material and comprises a straight shuttle engaging portion 15 and a reversely bent portion 16 terminating in an eye 17.
The shuttle check 14 is pivotally secured to the lay 10 by means of a stud 18 extending loosely through the eye 17 The opposite end 19 of the shuttle check 14 is curved outwardly, and engages a lug or projection 20 formed on the lay end and serving as a stop to limit outward or upward movement of the shuttle check. A spring 21 fixed to the lay at 22 engages the shuttle check at a point substantially opposite the center of the boxed shuttle. The shuttle check 14 may be faced with a strip of leather 23 or with any other suitable material if desired. v
It will be noted that the stud 18 is so located that the straight side surface of the shuttle extends somewhat beyond the stud toward the end of the lay when the shuttle is properly positioned in the shuttle box.
When the shuttle ,box is empty the spring 21 forces the check rearwardly into the path of the incoming shuttle. As the shuttle engages the shuttle check, the check is pushed outwardly against the pressure of the spring 21, which thus acts to check the shuttle. Furthermore, the curved portion 19 of the shuttle check soon engages the stop 20, thus putting additional spring pressure upon the shuttle. due to the resilience of the shuttle check itself.
The action of the shuttle as it enters the box is to force the portion of the shuttle check to the left of the stud 18 outwardly, and consequently to swing the reversely curved portion 16 inwardly. As the end of the straight side surface of the shuttle passes beyond the stud 18, however, the por tion 16 is forced outwardly and the entire shuttle check acts as a lever swinging about the stud 18 to exert increased pressure on the shuttle. This increased pressure holds the shuttle firmly in the shuttle box and effectively prevents rebound thereof.
I Having thus described our invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of our invention as expressed in the claims, and we do not wish to be otherwise limited to the details herein disclosed, but what we do claim is- 1. In a loom having a lay and a shuttle, a shuttle check comprising essentially a single member formed from one piece of resilient material, said member having one end fixed in relation to the lay and having a substantially straight shuttle-engaging portion, engaging said portion, said member having also a reversely curved portion at that end thereof by which it is secured to the lay.
2. In a loom having a lay and a shuttle, a shuttle check comprising a single continuous resilient member having a shuttle engaging portion, and a spring engaging and a spring fixed to the lay andsaid portion on the outer side thereof, said member having also a reversely curved portion atlone endv thereof pivoted to. the lay -ata point intermediate the ends of said shuttle engaging portion.
8. In a loom having a lay and a shuttle, a shuttle check comprising a "member formed from a single piece of resilient material andhaving 'a substantially straight shuttle engaging portion terminating at one end in a portion having a return bend, and a spring xed to the lay and swinging said member, the free end of said bent portion being pivotally connected to-the lay at a point intermediate the ends of said substantially straight portion. 7
L111 a loom having a lay and a shuttle, a shuttle check comprising a member 7 formed from a single piece of resilient material and having asubstantially 1 straight shuttle engaging portion terminating at one end in a portion having a return bend, and
5. In a loom having a lay and a shuttle a shuttlecheck comprising a single continuous resilient member having a substan tially straight shuttle engaging intermediate portion terminating at oneend in a reversely curved portion pivotally secured to the lay and at the opposite end in. an
outwardlycurved portion engaging a stop ;mediate portion thereof. a r
