IMPROVED MILLSTONE-PICK.
Specification forming part of Letters Patent No. 46,035, dated January 24, 1865.
To all whom it may concern:
Be it known that l, DEMMON U. STONE, oi Kingston, in the county of Ulster and State of New York, haveinvented a new and Improved Millstone-Pick; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art. to make and use the same, reference beinghad to the accompanying drawings, tbrming part of this specification, in which-- Figure l is a section of my invention, taken in the line .r m, Fig. 2. Fig. 2 is an end view of the same.
Similar letters of reference indicate like parts.
This invention relates to a new and improved millstone'picl; of that class which are constructed of thin steel plates and are fitted or secured in metal heads secured to a handle.
The object of the invention is to obtain a simple and efficient means for securing the pick-bladein the metal head, and one which will admit of the former being readily adjusted to compensate for grinding or wear, and which will also admit of the pick-blade being readily removed from the head when necessary.
A represents a wooden handle, and B ahead, which may be of malleable cast-iron and provided with a socket, (J, to receive the wooden handle. The head 13 is Formed or cast with a' rectangular opening, a, extending entirely through it longitudinally, as shown in Fig. 1.
This openingais slightlytaperone way, its two opposite broad sides being rathernearertogether at one end, b, than at the other end, b, and the broad side of the opening a opposite to the side where the socket U is formed with a rack 0, as shown in Fig. 1, said rack extending nearly the whole length of the opening.
1) represents the pick-blade, constructed of edge may proiect the proper distance out from the head, and, if desired, a head, B, may be cast with an opening, (1 of sufiicient capacity to receive a plurality of pick-blades, the latter being placed side by side and provided with lips d of difi'erent widths, so that they all may be fitted in the rack 0, the lip of one blade projecting over the one immediately below it, the blades being made otdili'erent lengths to admit of this and having the cutting-edges of the several blades all in one and the same plane. This would form a very convenient device for cracking the stones, as it is technically termed-that is, finely furrowing or wedging the stones between the main or deep furrows. The blade D may be detached from the head at any time by inserting a plate in the small end of the opening a and driving out the key 1 I claim as new and desire to secure by Letters Patent- The head 13, provided with an opening, a, extending entirely through it longitudinally, and having a rack, e, at one side, in combination with the key E and the lip d on theinner end oi the piclablade, substantially as and for the purpose set forth.
