PICKER-CHECK non LooMs.
Specification of Letters Patent.
Patented; Mar. 28, 1911.
Application filed April 4, 1910. Serial No. 553,180..
To all whom it may concern:
Be it known that I, SAMUEL WmKiNsoN, a citizen of the United States, and resident of Springvale, county of York, State of Maine, have invented an Improvement in Picker-Checks for Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing .like parts.
The object of this invention is to provide a simple and efiicient picker check for a loom.
The picker check embodying this invention operates by gravity so that it is not liable to get out of order; it is positive in its action, and maintains complete control of the picker at the end of its reciprocation.
The nature of the invention will more fully appear from the accompanying description and drawings and will be particularly pointed out in the claims.
The drawings represent a picker check embodying this invention with only so much of a loom structure as is necessary to a disclosure of the invention.
I11 the drawings, Figure 1 is a transverse cross section through the shuttle box at one side of the loom; Fig. 2 is a top plan view of a portion of one end of the loom showing the parts involved in the invention.
The invention is applicable to any form of loom employing areciprocating shuttle operated by a picker, and it is unnecessary to a disclosure of the present invention that the structure of any particular form of loom should be gone into in detail.
In the drawings is represented at l the wall of a shuttle box at one side of the loom, while 2 represents the usual binder. In Fig. 1 a shuttle is indicated boxed at 3.
The picker is shown at 4 as a block of rawhide mounted to slide on the rod 5 and provided with a fin or projection 6 by which it is guided. This picker 4 is operated in-the usual manner by a connection with the pin 7 from the usual picker stick, not illustrated, and, as is well known, when swung from a position at the right, viewing the drawing toward the left, picks the shuttle across to the other side of the loom.
In the preferred form of the present in vention a bracket 8 is bolted at 9 to the shuttle box and projects in an inclined or oblique direction upwardly therefrom and transversely thereof, and is formed with a suitable guideway 10 extending throughout its length.
The picker check is provided with a stem 11 fitted to slide in the guideway 10 and carries a head 12 of a thickness capable of fitting between the shuttle box and the picker. This head presents a Hat face adapted to fit against the side of the picker and curvedv at its forward end as shown at 13 to enable the picker to slide into contact with the flat face.
The operation of the device will now be apparent. When the picker has moved out of the path of the picker check, for example, to the position shown in Fig. 1 in full lines, the picker check will slide by gravity into the position shown in dotted lines in Fig. 1 and will rest against the rod 5. As the picker returns to the side of the loom it will contact with the curved face 13 of the picker check and raise the picker check in its guideway against the force of gravity until it slides into contact with the flat face of the picker check, and the picker check pressing with its flat face against the picker causes the latter to stop in substantially the same position as shown in dotted lines in Fig. 2, and then prevents the picker from rebounding or moving backwardly toward the opposite side of the loom. The hold of the picker check upon the picker being entirely frictional and there being no interlocking of the parts the picker can easily be moved from in front of the picker check at the next operation when the picker stick acts to move it to pick the shuttle to the other side.
Having fully described my invention what I claim as new and desire to secure by Letters Patent is:
1. In a loom the combination of a picker, a picker check mounted to move by gravity transversely of and. into the path of the picker whereby the picker is frictionally held by the picker check pressing against it transversely of its path of movement.
2. In a loom the combination of a picker, a picker check provided with a beveled ended head, means for mounting the picker check to slide transversely of and downward into the path of the picker to cause the head to come into frictional engagement with the picker transversely of its path of movement.
3. In a loom the combination of a picker,
a picker check provided with a beveled endcd head and mounted to slide freely obliquely, and transversely of the path of the picker and normally held by gravity in said path whereby the picker upon its return acts to raise the picker check and is stopped and frictionally held thereby.
4. In a loom the combination of a picker, a picker check provided with a beveled end- 10 ed head normally projected by gravity transversely of and into the path of the picker and elevated by the picker into frictional engagement therewith at the end of its backward stroke.
5. In a loom having a reciprocating picker a shuttle box, a bracket secured to said shuttle box and extending transversely thereof in an upward inclined direction and formed to present a guideway, a picker check having'a beveled ended head, and a stem inclined thereto and adapted to slide in said guideway into the path of the picker whereby the picker in its movement Will act to raise the picker check and be stopped and frictionally held thereby.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
SAMUEL WILKINSON. Witnesses:
