HMPROVEMENT IN HANoLEs Fora MILLsToNE-PICKS.

Specification forming part of Letters Patent No. 36,170, dated August l2, 1862.

To all whom it may conc-ern: l

Beit known that I, ANsoN ROWE, of Atalissa, in the county of Muscatine and State of- This invention relates to an improvement in the ordinary pick-handle, which consists of a piece of hard Wood turned at one end so as to be readily grasped and held by the operator and having its opposite end comparatively large in diameter, so as to form a hub or head, in which a taper hole is mortised to receive either end of the pick, which is of double-taper form. In this arrangement the pick is only secured lirmly in its handle when the taper of the former corresponds with the taper of the mortise in the latter, and as the picks are all forged by hand without the aid of gages or other means to determine their proportions or shape it follows as a matter of course that they will vary materially in form, and hence but few fit properly the mortise in the handle or stock.

The object of this invention is to obviate the difficulty above specified; and vto .this end I construct the hub or head of the handle or stock with an adjustable key or block, so arranged that the Inortise or aperature which receives the pick may, Without any special manipulation on the part of the operator, be

adapted to suit thepreeise form of the pick,

andl thereby cause the same to be firmly secured in the handle or stock.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the handle or stock ofthe pick, having one part, a, turned, as usual, of l a proper size to be readily grasped and held by the operator, and having a hub or head, b, at its opposite end considerably larger in diameter than a. The outer part of the hub or head b is slotted longitudinally a certain distance, as'shown at c, and the back edge of this slot is inclined, as shown` at d in Fig. 1. In the front part of this slot c there is fitted a key or block, B, and secured by a pin, e, which passes transversely through the hub or head b, and on which pin the key or block B is allowed to turn freely. The principal portion of the inner surface of this key or block B is a plane, as shown at f in Fig. 1, and the'upper and lower parts may be slightly beveled or formed of short planes g g, having an oblique position with f. The key or block B does not eX- tend back to the inclined edge d of the slot c, a space being allowed between them to receive the pick, as will be seen in Fig. 1, in which the pick is shown in red outline. By this arrangement it will be seen that when the pick is inserted in the space between the key or block B and the back inclined edge, d, of the slot c the key or block will, in consequence of turning on the pin e, adjust itself tothe pick whether the same have a greater or less taper and the latter be firmly secured inthe handle or stock, the inclined back edge, d, of the slot c giving the pick the proper inclination. Thus by this simple means the difficulty attending the ordinary pick handle or stock is fully obviated and much embarrassment avoided, as the picks are veryliable to fall from the ordinary handle, and if they strike the Inillstone angularly the corners of the pick are4 liable to break.

ANSON ROWE.
