WILLIAM ADAMSN, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN PULVEP.|Z|NGMACH|NES.
Specification forming part of Letters Patent No. 42,060, dated March 29, 1864.
To all whom it may concern:
Be it known that I, WILLIAM ADAMsoN, of Philadelphia, Pennsylvania', have invented certain Improvements in Apparatus for lulverizin g Quartz, Ste., and other Hard Minerals and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon. l
My invention consists of certain rollers and appliance used in conjunction therewith, and fully described hereinafter, for the purpose of pulverizin g broken quartz, einery, and other hard minerals.
- In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.
On reference `to the accompanying drawings, which form a part of this specification, Figure l. is a vertical section of lny machine for pulverizin g quartz and other hard minerals; Fig. 2, a transverse vertical section on the line l 2, Fig. l; Fig. 3, a plan view of the machine, and Figs. 4 and 5 detached sectional views of parts of the machine.
Similarletters refer to similar parts throughout the several views.
The frame-work of the machine consists in the present instance of the two longitudinal beams A and A. connected together by the cross-bars B and B', the whole being supported on suitable legs, C C. To each ofthe beams A and A is secured a frame of castiron, consisting of a plate, a., with two vertical pieces, b and b', forming a part of the plate, and the detachable cap c, best observed on reference to Fig. 5. Within each frame are coniined the two boxes D and E, the former being stationary and the latter being so arranged that it can be moved in a horizontal direction only.
F and F are two plain rollers, the journals of the roller F turning in the boxes D D, and those of the roller F' in the boxes E E. Each box consists of the upper portion, f, and lower portion, h, the two portions being arranged for the reception of the journal and its central collar, t. Near each end of each box, a 1d in both the upper and lower portions of tie same, is a recess for the reception of a strip, a', of cork or other like material, a bent rod, Gr, passing under the lower strip of cork,
and the two ends of the rods passing through. the upper portion of the box, above which they are furnished with suitable nuts, jj, as best observed on reference to Fig. 4.
To one end of each ofthe caps e of the boxframes is hinged a lever, H, and near the end of this lever is suspended a rod, I, which passes through one of the beams ofthe frame, below which the rod is surrounded by a tube, J, of gum-elastic, a nut, m, on the screwed end of the rod bearing against the end of this tube. A rod, R, is so connected to each lever, and
so arranged in respect to the box E, against which the rod bears, that on depressing the outer end of both levers the boxes E E will be moved toward the boxes D, and consequently the roller F toward the roller F. Two hori zontal plates, K and K', are secured one to each of the caps e of the box-frames, and to each plate is secured a vertical plate or fender, n, of the form or approximating to the form seen in Fig. l, each vertical plate being situated midway between the rollers and as close to the ends of the same as possible without being in actual contact.
The above-described machine has been es, peeially designed for reducing quartz and emcry to the proper condition for use in the manufacture of sand and emery paper. In order to pulverize these hard minerals with the desired ei'ect, I have found it necessary to pass them between a series of pairs of rollers and to regulate the force with which one roller of each pair is pressed against `the other, in
accordance with the fineness or coarsencss of the powder to be produced.
In order that the rollers may act with proper crushing effect it is essential that they should not be allowed any longitudinal play, otherwise their surfaces are rapidly deteriorated,
and they become incapable of performing the" they may not be worn unequally at different points, it is essential that the pieces of stone should be fed to the rollers from a hopper, X, (shown by dotted lines,) in a stream as wide or nearly as wide as the rollers are long; hence the use of the fenders n n, which retain this stream Within proper limits and preventthe broken stones from falling to the ground without passing the rollers.
To prevent the breaking of the machine, it is necessary that one of the rollers should yield in case any substance which cannot be pulverized accidentally falls between the roll ers, and it is likewise necessary that a pressure readily regulated should be imparted to the yielding roller. This is effectually provided for by the lever H, rod R, rod I, gumelastic cylinder J, and the nut lm.
I arrange a number of the above-described machines side by side, and use one general driving-shaft, W, Fig. 3, which turns in boxes X', one ot' which is secured to one of the boxi'rames oi' each machine, the driving-shaft having a number of cog-wheels, one of which gears into a similar Wheel secured to a projecting journal of one ofthe rollers of each machine.
I claim as my invention and desire to secure by Letters Patentl. The two rollers F and F', and the two fenders n n, in combination with a hopper, X,
' situated above the rollers and as wide or nearly WM. AD AMSON.
