Speccation of Letters Patent.,

Pulverizer, of which the following is a full,
clear, and exact description.
My invention relates to pulverizers, it being particularly adapted for the reduction of clay. It has for its principal objects the provision of a simple machine which may be economically operated.
Reference is to be had to the accompanying drawings, forming a part of this specifica-A tion, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation of one embodiment of my invention, parts being broken away and in section. Fig. 2 is a vertical transverse section therethrough. Fig. 3 isa perspective view of a portion of one of the u per ring-sections. Fig. iis a detail in top pan of a ortion of a beater-bar and its lades; an Fig. 5 is an enlarged transverse section through adjacent upper ring-sections,
showing the spacing-Washer in place.
The numerals 10 designate opposite sills, upon which are supported standards 1 1 1 1, connected by opposite side bars 12 12. Upon these bars is mounted a casing, which is shown l as consisting of a lower portion or hopper 13 and an upper or cover portion 14, preferably of semicylindrical form. Within this casing is situated a pulverizing chamber or cylinder, which preferably consists of separated rings, each formed in semicircular sections 15 and 16, situated substantially-concentric with the cover portion of the casing. The lower ringsections 15 are provided with horizontallydisposed lugs or projections 16a, which rest upon the horizontal members or angle-bars' 17, which are conveniently secured to the side bars 12 by bolts 18, they being spaced from the bars by thimbles 19 to removably maintain the cover portion of the casing upon these bolts. Said cover may be furnished with slots 20 in its lower edges which may engage the bolts, the cover lying between the ends of the thimbles and the inner sides of the bars 12. This enables the cover to be removed upon loosening the nuts of the bolts 18 without disturbing the other elements of the machine. The lower bar-sections have at each end a depression or concavity 21 to receive the extremities of the upper ring-sections 16. These have adjacent to their ends at their outer sides lugs or projections 23, with which may contact longitudinally-extending angle-bars 24, which are shown as connected to the bar 17 by a suitable number of bolts 25, these bolts serving to draw the bars together and clamp the sections firmly to one another and upon the supporting-bars. Each of the ring-sections is preferably tapered, it being here illustrated as having yat one side an inclined face 26. These inclined faces, with the straight faces of the adjacent rings, diverge outwardly, and thus avoid any tendency of the material to choke as it passes between them. Each of the bar-sections upon its inclined side has a suitable number of cylindrical bosses 27, the outer face of which lies in the plane of the outer face of the ring-body, through which are openings 28 to receive longitudinal tie rods or bolts 29,which maintain the rings in proper relation to one another. The space between the rings is xed by the interposition of washers 30 of suitable thickness between the faces of the bosses and the straight face of the adjacent ring. The inner edges ofthe upper ring-sections may be provided with teeth 30a to increase the reducing action.
Axially of the chamber extends a shaft 31, journaled in the standards and having upon its outer ends pulleys 32, by which it may be rotated from any convenient source of power. Fast upon this shaft within the chamber are spiders 33, to the arms of which are secured beater-bars 34. Each of these beater-bars carries a series of beater-blades 35, each of which blades is preferably inclined with relation to the axis to urge the material from one end of the machine to the other. This inclination preferably decreases from thefeed to the discharge end, thus maintaining the resistance to the rotation of each blade substantially constant as the amount of material operated upon decreases.
In the use of my improved pulverizer the beater-shaft is rotated at the desired speed and the material under treatment is intro-y IOO falls within the field of action of the beaters it is hurled bythem against the rings, which pre- IOS sent a large pulverizing-surface, the toothedl faces of the upper ring-sections furnishing a particularly effective reducing-surface. As the particles fall toward the bottom of the cylinder they will be again and again struck by the beaters, dividing them until they are of such size as will pass through the spaces between the rings, when they are received by the casing and directed by the hopper to a suitable bin or receptacle. This reduction progresses as the material is advanced by the inclined blades, and before it reaches a discharge-chute 37 at the opposite head of the machine from the feed-chute and opening at the extreme lower edge of the cylinder it will be in such a state of division that all will have passed into the casing except such resistive pieces as stone or iron, which will be delivered through the discharge-chute separately from the pulverized material. When the teeth upon the upper bar-sections become so Worn as to be ineffective for pulverization, the nuts upon the bolts 18 may be loosened, the cover portion of the casing lifted, when upon removing the -loolts 25 the top sections may be taken out and new ones substituted Without disturbing the remainder of the machine.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a pulverizer, the combination with a chamber comprising spaced rings provided with internal teeth, of a beater having inclined blades and being rotatable Within the chamber.
2. In a pulverizer, the combination with a chamber comprising a series of rings tapered outwardly throughout their peripheries and having integral bosses extending from the tapered portions, said bosses being provided with openings, of tie-rods extending through the boss-openings and serving to draw the outer faces of the bosses to a bearing, and a beater rotatable within the chamber.
3. In a pulverizer, the combination with a chamber comprising a series of rings, each of which has at one side a straight face and at the opposite side a tapered face, of bosses projecting from the tapered faces to the plane of the body of the ring and having openings,
tie-rods extending through the openings, and a beater rotatable Within the chamber.
4. In a pulverizer, a chamber comprising a series of separated rings, each of which rings is formed in sections having external proj ec` NICKOLAS SPURGIN.
