Specilieation forming part of Letters Patent No. 147,925, dated February 24, 1874; application filed J une 5, 1872.
To all whom t may concern:
Be it known that I, SAMUEL BIRTH, of Leeds, Yorkshire, England, gentleman, have invented certain Improvements in Picks for Cutting Coal and other Minerals, of Which the following is a specification:
This invention consists in the combination of a pick of peculiar construction with a removable point, as will be fully described hereafter.
Figure 1 represents a View, partiallyT in section, of my improved pick, With removable point: Figs. 2 and 3, different views of the p: k .fithout the point.
To enable others skilled in the art to make and use my invention, I Will 110W proceed to describe fully its construction and manner of operation.
A is the pick-point, inserted in the hollow or socket made for it in the end of the pickshaft B. C is the cotter, fitting into a groove or cotter-hole inthe socket, and in a corresponding groove in the stem of the pick-point. D is e Cushion, Qi `estiaaeibbQ1;.,.9r.9the,snit able elastic mat ,at'tl bottom of the elastic cushion being placed at the bottom of the socket, it might be placed.around the outer edge of the socket, as shown `in dotted lines at D', but when the cushion is so placed, it is necessary to have a projection or shoulder, F, on the pick-point, to rest on the cushion D. Metallic cushions to act as springs may be vused instead of cushions of india-rubber.
what I claim as new, and desire to secure by Letters Patent, is-
The combination of the socket B, point A, key C, and packing I), as and for the purpose described.
SAMUEL FIRTH.
