CHARLES F.. SMITH AND HARVEY HJRUMPEL, OF MILWAUKEE, WISCONSIN, AS-
SIGNORS TO SMITH ENGINEERING WORKS, O'F,MILWAUKEE, WISCONSIN, A 603- 1 POItATION OF WISCONSIN.
GONICAL GRUSHING MILL.
Application filed October 3, 1921. Serial No. 504,876.
To all whom it may concern: 1
Be it known that we, CHARLES F. SMITH and HARVEY H. RUMPEL, both citizens of the United States, and residents of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and usefulthe material travels between a conical concave and a conical crusher head'with their axes approximately horizontal but at an angle that will cause their crushing surfaces to converge toward the outlet, whereby the material traveling with the concave by cen trifugal force will be repeatedly brought between the crushing surfaces and progressively pinched as it advances toward the converging outlet so as to produce gradual'reduction.
With the above and other objects in view the invention consists inthe conical crushing mill as herein claimed and all equivalents.
On the accompanying drawing isa central sectional view of a conical crushingmill constructed in accordance with this invention.
In this drawing lOindicates-an approximately horizontal tubular shaft journaled in bearings 11 with a driving pulley 12 fixed thereon between the bearings. At one end teriorof the shaft, where it is acted upon by a: spiral worm or internal flange 14 to advance it through the shaft to the other end, in which a flaring crushing concave 15 is rigidly clamped, as by bolts 16. A conical crushing head 17 in the concave is mounted with roller bearings 18 on an arm 19 that is pivotally supported by trunnions 20 thereon working in bearing blocks 21 on the same base 22 as the bearings 11. This crusher head 17, while having no driving connection, is free to rotate around the arm 19 as it is impelled by its contact with the concave 15 or the material pinched between thrust bearing 23 against a flange24= of the a spout 13 delivers'raw material into the inthem. It is given a suitable double and arm, which is protected from dust and provided with lubricant by a" sleeve 25.
The arm 19 is held with pressure in the position in which the crusher head 17 contacts with the concave'or at a desired dis-,
tance' therefrom by means of a projection 26 thereon carrying a ball 27 on its end, which is held between a spring-pressed plate 28 on one side and a gage-plate 29 on the other, thegage-plate being fixed in place in a housing 30 on thebase to determine the position of the crusher head while the spring-plate 28 is held by springs 31 to resist an upward movement of the crusher head from such position, but permitting it to yield when necessary.
In operation the material fed through the shaft 10 falls into the crushing zone between the conical concave and conical crusher head, where it is pinched and carried around with the concave -by centrifugal force to be pinched again and. this 210- tion is repeated while the material pro gresses toward the outlet, since the active faces of the crushing members converge. In
this manner the material is repeatedly pinched between the crushing faces as it advances andthe reduction is gradual and the strain and wear on the machine is rotatably mounted conical concave on an much less than where the entire reduction approximately horizontal axis, and a conical crusher head within the concave with its axis at an angle to the axis of the concave, the crushing, zone between them converging toward the outlet end thereof.

an independently mounted conical crusher CHARLES F. SMITH. HARVEY RUMPEL.
