- CRUSHER AND PULVERIZER.

Patented July 16, 1907.

Application filed Hwy 19, 1906. Serial No- 817.788.

To all whom it may concern:

Be it known that I, OLIVER J. Moussn'r'rs, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New Yorkfhave invented new and useful Improvements in Crushers and Pulvcrizers, of which the following is a specification.

This invention relates to crushcrs and pulverizers, and one of the principal objects of the same is to provide. improved means for crushing and grinding the material within-a rotating casing.

Another object of the invention is to provide an im-- proved construction of lining for rotatable crushers and pulverizers.

These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which:

Figure-l is a side elevation of my improved crusher. Fig. 2 is a longitudinal sectional view of same. Fig. 3 is an end .view. Fig. 4 is a cross section of the same. Fig..5 is a detailed view of a portion of the lining which I used. Fig. 6 is a perspective view of one of the lining sections detached. 'Fig. 7 is a view of the" modified form of the lining. Fig. 8 illustrates another modified form of the lining. Fig. 9 is a detail view of a modified form of one of the crushing cones.

Referring to the drawings for a more particular description of my invention, the numerals 10 and '11 designate the frusto-conical hollow sections of the casing, said sections being provided at their inner ends with flanges 12 through which the securing bolts pass to hold said sections firmlytogether. The section 10 is pro-.

vided with a head 13; and the section 11.is provided with a mouth or nozzle 14 for the introduction of material .to be treated. Each section is provided with a supporting ring 15 which may be formed separately from the sections 10 and 11 and secured upon said sections by any suitable means. Brackets 16 to which a shaft 17 is journaled, are suitably supported adjacent to the rings 15 and the shaft 17 is provided with flanged rollers 21 for engaging the rings 15 and rotating the casing. A pulley 19 is secured to the shaft 17 for a beltileading to anysuitable source of power, and the shaft 17 is mounted in suitable journal boxes 20 on the brackets 16.

' The sections 10 and 11 ar'eeach provided with anguhr ofi-set portions 10,-11 designed to confine the liquid and material to be treated to the center of the and to prevent the same from splashing out at the mouth. 14. Each=section of the casing is provided with a hard metal lining 22 which may be made in sections and secured to the casing, as shown in Fig. 5.

'This lining may be made of porcelain or earthenware in sections, as shown in Figs. 6 and 7, said sections provided with flanges 23 secured together by suitable bolts. Ribs 24 extend longitudinally of the sections and between the ribs and between said ribs and flanges 23, a filling material is inserted to give greater-strength to the lining.

As shown in Fig. 8 this lining may consist of a series of rings composed of glass, porcelain or earthenware and disposed edge to edge, and secured inany suitable manner.- v

In a device oi'this character there is considerable wear on the lining and to provide a lining which may be removed when worn is one of the objects of this in-" vention. v

The crushing and pulverizing is accomplished by means of the hollow frusto- conical crusher members 25 and 26, each provided at the smaller end with a cross piece 27 and 28, which are perforated to accommodate a rod 29 having a head 30 at one end, and the opposite end being threaded to receive a nut 31, the rod serving to hold the two members of the crusher together at their lower edges and their upper edges being slightly separated to receive the material to be ground and crushed. As shown in Fig. 9, the crushing faces 32 of the grinding members extend at an inclination from the central portion, and a rod or bar extends centrally through the section and is provided with an eye 33 by means of which the two sections may a suitable link. p

Having thus described the invention, what I claim is:

1. A grinding and pulverizing mill comprising hollow trusto-conlcai sections, each provided with an ol'fset portion for the purpose descrlbed,- conical crusher members mounted wlthln said hollow sections, and means for rotating said sections and crusher members,

2. In a grinding and pulverizing mill, the combination of hollow trusto-con'ical casing members provided with a lining, ofi-sets in said sections, conical crusher members within the casing, said crusher members being connected by a rodsecured at the ends of the members, and inclined be connected by races on said members, substantially as described.

In testimony whereof, I am: my signature in presence at two witnesses. g
