To all whom it may/. concem:

Be it known' that I, ANDREW B..LIP'SEY, of` West `Hohoken,"in the county of Hudson and State of New Jersey, have invented certain Improvements` in Pulverizing-ll/Iachines, of

One improvement consistsin the combination of a series of chambers of' successivelylarger diameter, arranged one outside or be yond the periphery of another, and series of tremely-compact, simple, and serviceable pulverizing-machine is produced.

Another improvement consists inthe combination, with a chamber provided with.' a `series of revolving beaters,of a chamber of larger diameter, communicating with the former, and provided with a series of beaters, revolving in the same length of time as thoseV in the at a greater speedq producing `a partial vact num and drawing from the smaller chamber the lighter particles of the material therein pulverized, whereby I produce a very simple and superior pulverizing-machine, which may be operated with a very Asmall amount of power.

Another improvement consists in the com-` bination, with a chamber `provided with a se ries of revolving beaters, of a chamber of' larger diameter, communicating directly with the smaller chamber, and provided with a series of beaters, supported on the same shaft as those of the said smaller chamber, and revolving in the same length of time as thelat-` ter, whereby I produce a simple and exceed- Another improvement consists in the combination of two or more chambers, communicating one with another, and provided each with a series of beaters for revolving therein, andialsoprovided with lips overlapping the beaters of each chamber, which communicates with another, whereby material to'be pulverized therein is prevented from passing out of one chamber into another, except at the proper place.

Another improvement consists in the cominlet for supplying material to be pulverized,

and air, or its equivalent, thereto, of means for regulating or shutting off the supply of" material, and air, or its equivalent, whereby provision is afforded for supplying them in the proper relative proportions, in such manner that theY air orv its equivalent will 4not interfere with the said material in its passage through the machine, and for entirely Yshutting olf the bination, with a beater extending longitndinally outward from the side ofa disk or spider of a renewable shoe, fitting or lapping over over the face, inner` edge, and outer end of such beater, a dowel or projection on the outer end of said beater fitting a cavity in the contiguous portion of the shoe, and a rivet or bolt atthe inner end Aof the shoe securingrit to the aforesaid disk or spider, whereby pro 'vision is afforded for properly securing the shoe in place withoutperforating, and thereby weakening, the beater transversely.

Other improvements consist in details of construction, to be hereinafter explained.

In the accompanying drawing, Figure l `is a partly-sectional side view of a pulverizingmachine embodying my improvements.` Fig. 2 is a transverse section thereof. Fig. 3 is a transverse section of a pulverizing-machine of slightly-modified form, also'embodyin g my improvements. edge of a beater, its shoe, and a portion of -a disk supporting it.l Fig. 5 is a face view of a beater, its shoe, and a transverse section of a portion of the said disk supporting it 5 and Fig. 6 is an end view of a beater, a transverse Y Vrection indicated by the arrow-heads, also including a portion of the said disk supporting the beaters.

Fig. 4 is a view of the outerV Similar letters of reference designate corre' sponding parts in all the figures.

A designates a chamber, preferably of cylindrical form externally,'as well as internally, and VB designates a series of beaters capable of being revolved therein. C designates an inlet for the material to be pulverized, and air, or its equivalent. It is shown as communicating with the chamber A at the side, vand is provided with a throttle, D,'which may be shifted to regulate the passage of the material to be pulverized, and air, or its equivalent,into the chamber A- The throttle, though represented as consisting of a simple cock, ,may consist of ,a slide, or any other device which may be made to effect the throttling, narrowing, or closing 'of the inlet.

Above vthe throttle the inlet is preferably provided with a hopper -to receive the material to be/pulverized from a feeding-chute, E, and the spacebetween the'klatter andthe hopper affords provision for the entrance of air or its equivalent.

Great Aadvantages result `from admitting and regulating the admission of the material to be pulverid and air or its equivalent by the same means into a` pulverizingmachine. In this way one continuous p as- ,sage of both ythrough the machine may be effected, the disturbance of the material to be 1 the machine.

The beaters B are preferably provided with renewable shoes, hereafterito be described, and are shown as supported by a spider or disk,

vS, which is xed to a suitably-supported rotary shaft, F, and may serve to form one side of the said chamber A. A1 designates a chamber, which is of larger' diameter than the chamber A, communicates therewith, and preferably is also cylindrical externally as well asinternally. B1 designates a series of beaters supported -by a spider or disk, S', fixed to a rotary shaft, F, and capable ofrevolvingwithin the chamber A1. A2 designates a chamber, which is of larger diameter than the chamber A1, communicates therewith, and is ,preferably also `cylindrical externally as well as internally.l yB2 designates a series of beaters capable of being revolved within the chamber A2.

The chambers A and A1 communicate, respectively, with the chambers A1 and A2, and are shown as communicating therewith at the sides.

`on the same shaft.

outer parts of the beaters B and B1 of the chambers A and'A, so as to prevent the material pulverized in these chambers from passing into the chambers with. which they, respectively, communicate.

In order to provide for placing the beaters in their position for work, the inwardly-.projecting parts of thev lips Gr G are notched, as shown in Fig. 1, to permit them to pass beyond them.

The exit-opening H H1 of the chambers A and A1 are :shown as ybeing made by leaving off lportions of the lips G and G', and for the sake of clearness are blackened throughout their extent. They may, however, be made in any other suitable manner. Provision is afforded for the exit of the pulverized material and air or its equivalent from the chambervA2 by two openings, H2, in its periphery, (shown one in Fig. l and both in Fig. 2,) and also blackened throughout their extent. These exitopenings preferably communicate with an outlet, I, supported yon the chamber A2 or otherwise, sol that by means of' a set-screw, a, clamping it to its support-tackle consisting of cords and pulleys or other means-it may be adjusted at different angles without severing its communication vwith said exit-openings H2, and may be securedin position.

The outlet I, in order to afford provision for automatically separating line and light from coarse and heavy particles of the pulverized material, is provided, preferably at the bottom, with an opening or openings, o, which may with advantage be rearwardly inclined. When supported as represented, this outlet I is ,preferably provided with an adjustable top portion, which may be shifted, so that none of the pulverized material can escape under any circumstances. For instance, when the outlet is elevated the main top portion will ymove inward under the adjustable top portion,

and when the said outlet is depressed the adjustable top portion will be moved inward.

As represented in Figs. l and 2, the several chambers A A1 A2 are made in one piece, and the chamber A1 is outside the chamber A, and the chamber A2 outside the chamber A1; but in Fig. 3 the chamber A1 is arranged at the side of the chamber A, and the chamber A2 is arranged at the side of the chamber A1, but in both examples the spiders or disks for supporting the several series of beaters are shown as made in one piece, and are rotated They may be made in either of these ways with advantage, especially the former, as `thus the greatest compactness may be obtained; but they may also be any suitable manner.

J designates a cover, which is arranged outside the spiders or disks supporting the beat- I ers and covering them.

An important advantage of making each fseAol e f l er taylor the chambers extenany cylindrical is, that it may be moved from `place to place The operation is as followszfMate/rial to be 1 pulverized and theproper relative proportion y tion of such material. The beaters B1, revolving in the chamber A1 in the same length of time as the beaters B in thechamber A, but

" moving at a greater speed, owing to the increased radii of their revolution, produce a partial vacuum at the exit-opening H of the chamber A, draw from the latter the lighterparticles ofthe pulverized material, and cause them to be pulverized still more.` rlhe beaters B1, revolving in the chamber A2 in the same length of time as the beaters B and B1 in the chambers A and A1, but moving at a greater speed,` owing to the increased radii of their revolutioi'produce a partial vacuum at the exit-opening H1 of the chamber A1, draw from the latterthe lighter particles of the pulverized material, cause them to be pulverized still more, and discharge them into the outlet I. This outlet may be inclined upward,

, so that the force of the escaping air, or its equivalent, will be sufficient to carry only the lighter particlesout through the end thereof, and the heavier particles will then be discharged out of the openings o.

Any number of the said chambers may be used. For pulverizing some materials more may be needed than for pulverizing others.

Itwill have been seen that `by these improvements` I provide for making a very simple and exceedingly compact pulverizing-machine, which can be operated with but a small amount of power,and can be easily managed and moved from place to place.

When pulverizing moist material it may be advantageous to arrange the exit-opening of the chamber from which the material is to be delivered near the bottom, and to an apartment below.

It is` obvious that additional series of beaters might be arranged on the other sides of the spiders or disks S, S1, and S2, to work in another set of chambers without entailing the expense of additional shafting and other parts. It is also obvious that a number of sets of beaters and chambers may be arranged side by side on the same shaft, with economy.

I will now describe the removable shoes or faces K for the beaters, and the meansfor securing them in place, premising that they are not the only `Kind that maybe used.

These shoes K are preferably made of steel, and cover the faces and the inner sides and the ends of the beaters which are farthest from the spiders or disks S` S1 S2.` By overlapping at the inner sides ofthe beaters they are secured againstoutward displacement by centrifugal force. Theyare secured against Ymovement outward by pins or dowels c, projecting into'them from the beaters. Bivetsf, .impingingon the outer sides of the disks or spiders, `secure them against displacement llengthwise. Thismanner of securing them is very desirable because of itsV simplicity and effectiveness. l
