IMPROVEMENT IN' DEVICES IE'R ATTACHING- PICKER TO PICKER-STAFF.

The Scheule referred to in these Letters Patent and making part of the same.

T' all 'whom it may concern:

Be it known that. 1, JOHN D. BAninn, of Lawrence, inthe county of Essex and State of Massachusetts, have invented a new and useful Improvement in Attachmentof lickers to Picker-Staff; and l' do hereby declare that the following is a full and exact description of the construction and operation of the same, reference'heing had to the accompanying drawing making a part of this specification.

Figure I is a front view.

Figure II isa side view.

Figure III is a view of the rear, showing the wedgeadjustments,

The shuttles of nearly all the looms now in use are l thrown to and ti'o by means of a picker usually made ot' leather or raw-hide, and attached to a vi.

hrating staff two or three feet in length.

'My improvement relates solely to the mode of fastening the picker to the stnii, the object being to hold it irmly in place upon the stati', so that theshuttle may 'always strike in the saine place upon the pickel'.

By the modes of fastening commonly used, the picker changes its place, and the tip of the shuttle not striking fairly in the cavity designed for it, the shuttle is thrown out ot' the loom.

lhe letters of referel'ice rela-te to the same parts in all of the figures.

The lower end 4of the picker B traverses in a slot in the shuttle-box of the loom, and the fastcnings, to be described, are applied to the upper end.

This end is held fast to the staff by the clamp D E, which usually made of malleable iron, theclamp being of rectangular form, and long enough to allow of the insertion of' the ironwedge I as represented in figs. II and III.

This wedge ts close to the staff, and the bevel of its outer edge conforms to the inside of' the end of .thus formed it can be raised or lowered at pleasure,

without interference with the screw.

The holes J J J" are bored at the rear edge of the l sta, and may be about one-quarter of an inch apart. They receive the screw H, which rests in a groove madein the top of the wedge I, and entersl the staii' A, thus holding the wedge down, and preventing any lateral motion.

One or more short pins, l) I, may he insert-ed at. the endl) of the clamp, and project far enough on the inside to take a bearing on the picker B.

The shuttle strikes at the point (l, which is ret-anual firmly in one position.

'In some cases I extend the wedge I to the point- Q, fig. III, and in this ease the screw H passes through a hole in the 4top of the wedge.

The projecting shoulder- R, ig.-II, may be on either side of the wedge.

Instead of the round hole in the clamp to receive the screw Gr, a slot may be made, 'as shown by the.

parallel dotted lines S S, or the screw G may be placed at the lower edge of the clamp, lthe object or use ol'A this screw being to keep the end E of the clamp in place. f

W'hat I claim, and desire to secure by Letters .latent, isy The combination of the clamp, the forked wedge, and the binding-screws, with the picker and sta-li', substantially as herein described.
