IMPROVEMENT IN QUARTZ-CRUSHERS.
Specication forming part of Letters Patent No. 114,257, dated September 13, 1864.
To @ZZ whom it may concern.:
Beit known that I, A. W. HALL, ofthe city, county, and State of New York, have invented a new and Improved Mill for Crushing Quartz and Other Substances; 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 being had to the accompany ing drawings, forming part of this specication, in which- Figure 1 represents a vertical central section of my invention, taken in the line w m,
Fig. 2; Fig. 2, a plan or top view of the same; Fig. 3, a vertical section of a portion of the same, taken in the line y y, Fig. 2.

This invention relates to an improvement in the old and wellknown mill used for crushing substances, composed of a heavy circular crusher placed on a horizontal radius-shaft and fitted in an annular trough, in which the crusher rotates, and in which the material to be broken or ,crushed is placed.
The object of the present invention is to obtain the necessary pressure for the crusher without depending upon the gravity ofthe latter, as hitherto, which renders this class of mills very cumbersome, their transportation from place to place expensive, and their first cost very considerable.
The invention has further for its object the graduating of the pressure of a scraper, (one or more,) whereby the quartz may always be kept under the crushers or within the path of theirmovement, and the scraper or Scrapers always made to act efficiently and without any unnecessary friction caused by undue pressure.
A represents a foundation or base, on which i an annular trough, B, is firmly secured, and
C is an upright shaft, which has two horizontal arms, D D, projecting from it at opposite points, and on which two circular crushers,
E E, are placed loosely, and which work within the trough A, the shaft C being at the center of the trough B.
On the arms D D, just inside of the trough B, there are placed loosely two wheels, F F, on which a horizontal frame, G, rests, said frame having an annular plate, H, attached to its under side, said plate bearing on the wheels F. The shaft C passes up through the center of the frame G, and has a pulley, I, on its upper end, the lower end of the shaft C being fitted loosely -in a step, a., at the cen ter of the base A.
J represents a series of upright rods attached to the base A, in the form of a circle, and passing through arms 1), which project radially from the frame G, said arms having circular plates c on their upper surfaces, through the centers of which the rods J pass, said rods having screws cut on their upper ends, on which nuts K are fitted. These nuts K are each provided. with two arms, d d, and these arms are tted eccentrically in circular plates e at the ends of levers L, said plates forming cams, which, when the levers L are raised, bear on the plates c and press down the frame G, and cause it to bear upon the wheels F F, which do not bear upon the base A and press down the wheels or crushers E E. A pressure may also be obtained on the crushers E by turning the levers L and nuts K, the cams e being used after the nuts K are turned. The object of the cams is to suddenly relieve the crushers of the pressure when required-as, for instance, at the coinmencement of the operation, after the mill has been stopped, in order that it may be readily started, the pressure being gradually applied, if necessary, after starting. By this arrangement it will be seen that a requisite pressure may be given the crushers, and the same be quite light, as gravity is notdepended upon for pressure; and as the frame G may be of wood, as well as the foundation or base A, the parts may be readily transported from place to place. In fact, the iron parts-to wit, the trough B, shaft C, arms D D, crushers E, wheels F, rods J, and the levers L-are all that are required to be transported to distant places. In mining districts the wood-work may be made in almost any locality where a mill of the kind is required. Thus it will be seen that I obtain all the advantages of the old mill, without any ofthe disadvantages-to wit, great weight and expense of' construction and transportation.
M is a shaft, which passes through the shaft C at right angles to the arms D D. On one end of this rod there is secured a thimble, (LX,
to which a curved rod, N, .is permanently attached. This rod N is bent or curved in U form, so that it will have a certain degree of elasticity. (See Figs. 2 and 3.) To the lower end of the rod N there is attached a` scraper, O, which is of V form, open at the center, and of such a width as to extend entirely across the annular trough B, as shown in Fig. 2.
P is a screw, which passes through the upper end of the rod N, and bears upon the lowerpart'of said rod. By means of this screw the scraper O may be made to bear with a greater or less pressure on the bottom of the trough B, as may be necessary, in order to render the scraper eflicient in gathering the quartz and bringing it within the path of the Crushers E. The scraper, it will be seen, collects the quartz from the sides of the trough, the former pass ing over the center of the rear end of the scraper, the upper edge of which is inclined, as shown clearly in Fig. 3. Thus by this simple means I can with a light scraper obtain all the pressurel necessary to act upon the quartz in the trough B. If gravity were depended upon to obtain the pressure, a heavy scraper would be necessary, and in many cases where a great pressure would not be required considerable unnecessary friction would be created.
I do not confine myself to any precise form for the rod N, for that may be modified very materially and the same end attained. For instance, the rod may be rigid and attached by a hinge to an arm on the sha-ft M.
A scraper may be applied to each end of the shaft M, although one only is represented in Fig. 2.
I claim as new and desire to secure by Letters -Patent 1. The wheels F F, in combination with theV crushers E E, (one or more,) placed on the radius-arms D D, the pressure-frame Gr, and the annular trough B, substantially as and for the purpose set forth.
2. The screw-rods J, nuts K, and-cams e, all arranged with the frame G for applying the pressure to the Crushers E, substantially
