UNITED STATES PATENT OFFICE.
JAMES BARDSLEY AND ALLEN W. GORDON, OF WILLIMANTIO, CONN.
IMPROVEMENT IN PICKEPLS FOR LOOMS.
Specification forming part of Letters Patent No. 412,456, dated April 26, 1864.
To all whom it may concern Be it known that we, JAMES BAEDsLEY and ALLEN W. GORDON, both of Willimantic, in the county of Windham and State of Connecticut, have invented a new and Improved Fastening for the Pickers of Power-Looms; and we do hereby declare that the following is a full, clear, and exact description of the same, reference bein ghad to the aocompanyin g drawings, making apart of this specification, in which- Figure l is a side view of our invention and of the upper part of a picker-staff to which it is applied. Fig. 2 exhibits a vertical section of the picker and fastening and a side view of the staff. Fig. 3 is a top view ot' the picker and fastening.
Similar letters of reference indicate corresponding parts in the several figures.
This invention consists in a novel and very simple device for attaching the picker to its statt, which provides for its adjustment to the proper height, and which strengthens the staffl instead of weakening it, like the ordinary mode of attachment.
To enable others skilled in the art to make and apply our invention, we will proceed to describe its construction and operation.
A is the staff, and B the piece of hide, leather, or other material which constitutes the picker. U is a clasp, made of one piece of wrought or malleable iron, or of two or more pieces rigidly united, so as to be equivalent to one piece; and D is a set-screw, which, combined with the clamp C, completes the fastening. The upper part of the said clasp is of a size and form to receive within it the staff and the uptwo diagonal strap-like portions, c, which occupy positions on each side of the picker-sta. The set-screw is tted to a tapped hole in the front of the upper part of the clasp.. The back portion of the upper part of the clasp is made beveled or slanting, so that it can only bear with its lower edge against the back of the staff, as shown at b in Fig. 2, and this bearin g'point b is below the screw D, so that when the picker has been placed in the clasp and the latter has been placed over the lhead of the picker-staff the screwing up of the screw D against the upper part of the picker not only secures that part of the picker to the staff, but causes the clasp to act as a lever, of which the fulcrum is atb, and by that means causes the' lower part of the clasp to be pressed against the lower part of the picker and to clamp that part of the picker to the staff. The single Y screw is thus made to secure both the upper and lower parts of the picker to the staff, while it in no way interferes with the proper action of the picker.
This fastening is much more simple than other metallic picker-fastenings, and occupies
