Description
UNITED STATES To all whom it may concern:
Be it known that I, ELIsHrL RoBBINs, a citizen of the United States of America, and a resident ofA Hopedale, in the county of Worcester and State of Massachusetts, have invented anew and useful Mechanism for Supporting and Operating the PickerStaft of a Loom for Weaving; vand I do hereby declare the same to be fully described in the following specification, and represented by the accompanying drawings, of which- Figure l is a side elevation of a picker-staff and the sword of the lay of a loom as provided with my invention. Fig 2 is an end or edge elevation of the same. Fig. 3 is a top view of the curved supporter of the picker-staff. Fig. 4 is a top View, and Fig. 5 a side View, of the metallic foot of the picker-staff as separated from the said staff.
The nature of my invention consists in the arrangement of certain ears or cammed bearers, capguides, and the picker-staff with the foot thereof, and the supporting arm or rail of such foot; also in the arrangementY of a counteracting weight with reference to the pickerstafr", its curved bearing, cap-guides, and metallic foot.
In the drawings, A denotes a picker staff, and B the sword ofthe lay of a loom. Freni the said sworda curved arm or supporter, C, extends and has its upper surface inclining downward as it proceeds outward.
On each side of the arm or supporter C, and `at a distance from its outer end equal to about one-third ofthe entire length of the said part C, there is affixed an ear or cammed bearena, the same having the form shown in the drawings. l
A long metallic foot, D, having its lower edge straight, or about so, rests on the top of PATENT OFFICE.

llVlPROVEMENTlN PICKER-STAFFS FOR LOOIVIS.
Specification forming part of Letters Patent No. 35,395, dated May 27, 1862.
the supporter and is provided with curved shoulders or caps b b, which project upward from it, as well as laterally, and are to rest, respectively, against the inner curved sides of the two cammed bearers a a while the foot is between them. The picker-staff is bifurcated at its lower end, and straddles both the foot D and the supporter C, and is fastened to the foot by means'of one or more screws, c,which should go through it and be screwed into a standard, d, projecting upward from the foot.
The heel ofthe foot D is constructed with a weight or projection, e, sufficiently heavy to retract the picker-staff after each throw of a shuttle by it. While the curved shoulders or caps b b are to prevent the foot D from slipping oft the supporter G in a longitudinal direction during the retraction of the pickerstaf, the cammed bearersa a constitute shoulders or ahutments for the lower part of the picker-staff and to maintain its foot in its proper place on the supporter d uring the throw of a shuttle. The curve of the upper part of the supporter is intended to be such as will cause the picker, when attached to the head of a staff, to travel in a straight line through the shuttle-box.
My improved arrangement for supporting the foot of the pickerstait has been found to be very efficient, durable, and serviceable in practice.
I claim- -The arrangement of the cammed bearers a a, their shoulders or caps b b, and the pickerstaft with the footD and supporting-arm C, as described.
