MECHANVISM `FOR PREPARING ROCK, &c., FOR FERTILIZERS AND CEMENTS.

SPECIFICATION forming part of Letters Patent No. 349.229, dated September 14, 1886.

Application filed January 19, 1886, Serial No. 189.040. (No model.)

To @ZZ whom, it may concern:

Be it known that I, VICTOR LORD, a citizen ofthe United States, residing at Odessa, in the county of New Castle, State of Delaware, have invented a new and useful, Improvement in Mechanism for Preparing Rock, &c., for Fertilizersand Cements, which improvement is fully set forth in the following specification and accompanying drawings, in which- Y Figure l represents a partial side elevation and partial vertical section of mechanism for preparing rocks, Src., for fertilizers and cements embodying my invention. Fig, 2 represents a partial top or plan view and a partial horizontal section thereof, Figs. 3 and 4 are views of detached parts.

Similar letters of reference indicate corresponding parts inthe several figures.

Myinvention consists of mechanism for preparing rooks, &c., for fertilizers and cements, wherein provision is made for separating the fine and coarse particles thereof and collecting the same and returning the coarse particles to the mill to be reground and again sub- 25 jected to the bolting operation, as will be hereinafter fully set forth and claimed.

Referring to the drawings,'A represents a mill for breaking or crushing rock, cement, &c., thesame being in communication with an elevator, B, by means of a pipe o r tube, C.

Connected with the top of the casing of the elevator B, is a chute, D, which extends in an inclined direction to a box or case, E, which is adjacent to a bolt, F, the latter being properly mounted and operated in any suitable manner. On the under side of the chute D is a sieve, G, and below the same is a spout, H,

which is connected with a pipe, J, the latter entering the bolt F.

K represents an elevator, which is properly supported, and has the upper endl of its casing in communication with a separator, L, for tine and coarse particles of roclg, Src., supplied to the elevator from' the grinding mills M, which latter are in communication with the elevator by means of pipes or spouts N. The separator L is formed with compartments L2 L. At the top. of the compartment L2 is a sleeve, P, and at the bottom thereof a pipe, Q, which leads to a fan, R, the latter being properly supported.

Connected with a branch of the fan-case is pipe, T, the pipe S leading tothe elevator B and the pipe T to a bag or case, U, the upper portion whereof is formed of burlap or other similar material, the bottom of said bag having a discharge pipe, U'.

Adjacent to the bag U is a bag, U2, which is in communication with saidbagU bymeans of a pipe, U3, of burlap or other suitable material, said bag U2 having a discharge-pipe, U", both bags being properly supported.

Connected with the bag U2 is a pipe, V, which leads to a chest, W, and leading from said chest is a pipe, X, which opens into the atmosphere, said pipes V X being formed ot' burlap or other suitable material. The bolt has different grades of meshes, and below the same are chutes Y Z, the chute Y directing the fine material that has been bolted to a place of-eollection, and the chute Z being in communication with a pipe, Z', which leads to one of the mills M. The lower end ot' the bolt has adjacent to it a chute, A', the same having connected with it a pipe, B', whose lower end is in communication with the case of the elevator K.v It is remarked here that a series of balls, C', are employed in the bolting opera tion, the same being directed into the bolt so as to act on the material therein, and to assist to bolt the same, said balls escaping into the chute A', and then entering the pipe B', from whence they are directed into the elevator K, and conveyed to the separator L, where, rolling over the sieve l?, they reach the pipe J, and are so caused to re-enter the bolt. The bottom of the case E is inclined, as at D', and to the side of said case, near the lower. end of said bottom, is secured pipes E', which lead to the mills M.

F' represents a shaft, which is provided with pulleys whereby power may be communicated to certain parts ofthe bolting mechanism, said shaft being properly mounted above the sepa` rator L, and carrying jogs G', which engage with a collar on a rising and falling arm, H', whose lower end is attached to a projection, J', on sieve l). This proj ection passes through the top wall of the separator L, and is adapted to vibrate the sieve l) therein for assisting the action of said sieve.

In the horizontal part of the pipe X, where it leaves the chest W, are openings K', forming a pipe, S, and with the wall of the case is a IOO outlets for directing the fine bolted material from said pipe.

The operation is as follows: The rock, cement, Src., is broken or crushed in the mill A, and is directed by the pipe C to the elevator B, by which it is conveyed to the chute D. The finer particles fall through the sieve G- into the spout H, and are. passed by the same through the pipe J into the bolt, from which the fine particles fall into the spout Y, andare thus directed to a place ot' collection. The tailings from the bolt enter the spoilt Z, and are conveyed by the pipe Z to one of the mills l\'l,whcre they are ground. The coarse particles in the chute D escape into the case E, and are directed by the inclined bottom thereof to the pipes E', and so reach the mills M, wherein they are ground. The materials ground by the mills leave the same and reach the elevator K by means ofthe pipes N, and enter the separator L, where the tine particles escape through the sieve P into the compartment L, and so reach the pipe Q, whereby they are conveyed to the fan R. The coarscr particles pass over the sieve P and enter the compartment L, and escape therefrom into the pipe J, thus reaching the bolt F,where they are subjected to the bolting action, the tine particles and tailings dropping into thespoutsY Z, from whence they are collected and reconveyedsimilar to the material admitted to the bolt through the chute D. The light material from the pipe Q reaching the fan is blown by the latter into the pipe or chute T, and from thence into the bag U. \Vhatever heavy material enters the pipe Q and leaves the fan-case with thelighter particles, drops into the pipe S, so as to reach the elevator B, and thence the chute D, and eventually one of the mills M, where it is reground. Some of the light material in the bag U is blown through the pipe U3 into the bag U'i, then into the chest lV, and tnally through the pipe X, where it is discharged at the spouts or openings li into suitable bags, ezc., provided to collect the same. The main portion of the light material admitted into the bags or hoppers U U" escapes through the discharge-pipes U U at the bottom thereof, whereby it may be collected in any suitable manner. The air driven into the bags U Ul and pipes U3 and V serves to keep the tine particles from matting, but escapes through the burlap or material of which they are formed, avoiding blowing of said particles into the atmosphere at the outer end of the pipe X, said end, however, permitting the escape of what little air enters said pipe. Should the bolt be rendered unserviceable from any cause, the sieve or screen P is raised or removed, and the material from the elevator K is discharged into the compartment L2 of the separator and directed into the pipe Q, which is provided with a valve or cut-ofi', M,which, being opened, permits the escape of the material into a pipe or chute, M, which leads from the pipe Q. to the spout Y, and conveys the same to the latter, from which it may be discharged.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
