' MILTON F. WILLIAMS, OF ST. LOUIS, MISSOURI, ASSIGNOR TO WILLIAMS PATENT CRUSHER PULVERIZEB.

MISSOURI.-

ORE-CRUSHER.

Specification of Letters Patent.

Patented Aug. (8, 1912.

Application filed August 28, 1911. Serial No. 646,530.

To all whom it may concern:

Be it known that I. MILTON F. WILLIAMS, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Ore- Crushers, of which the following is a full. clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference belnghad to the accompanymg draw- 1ngs, forming part of this specification, 1n

Figure 1 is a side elevational view of my improved ore crusher partly in section. Fig. 2 is an end elevational view looking at the discharge end of the machine. Fig. 3 is a vertical cross sectional view.

This invention relates to a new and useful improvement in ore crusher-s designed particularly for crushing or disintegrating conglomerate ores, the-object being to construct a machine of the characterdescribed so that it will be simple, cheap and easy of repair and one which will confine the dust incident to the reduction of the ores.

lVith these ob ects in view the 1nvention consists in the construction, arrangement and combination of the several parts allas will hereinafter be described and afterward pointed out in the claims.

In the drawings, 1 indicates the sleepers upon which the frame work is mounted this frame work preferably consisting of com mercially rolled flanged members appropriately riveted together toprovide supports for the bearings in which the removable parts of the machine are mounted.

2 indicates the side frame members and 8 the end frame members.

1 are universal bearings mounted upon the end frame members in which is tjournaled a shaft 5 carrying a pulley 6 at one end.

.On this shaft 5, within the reducing chamber are strung a series of flexible hammers '7 preferably arranged in spiral series, said hammers compr1s1ng head port1ons which are connected by chains 8 to the oppositeside of split collars clamped on the shaft.

The grinding cylinder is composed of a series of longitudinally disposed bars 10 appropriately spaced apart and whose ends are mounted in clamping rings 11 which rings are provided with track portions 12 for cooperating with supporting wheels 13. These wheels 13 are mounted on shafts 14 arranged in suitable bearings supported by the end framing so that there are two wheels at each end of the cylinder. Each of the shafts 14 carries a sprocket wheel 15 over which passes a chain 16 for revolving the shafts 14; in unison. A pulley 17 is mounted on one of the shafts 14 by which the power is coming is in the'form of a discharge trough through which the material passing between the bars 10 drops onto a conveyor belt or into a receptacle located under the machine.

The material to be disintegrated is fed into one end of the machine through a hopper 19 and is subjected to the action of the hammers or heaters, the cylinder; being rotated in the meantime so as to tumble the material in the reducing chamber and present different faces thereof to the action of the hammers. As the material is fed into the machine, it practically builds up a bed in the bottom of the cylinder and as' this bed increases in height it will overflow at the discharge end of the machine so that any uncrushable material in the machine will pass out as tailings. The discharge end of the. machine is therefore provided with a restricted opening formed by a flanged ring 20 having inwardly and outwardly flared rims so as to provide an external V shapedthat 600 revolutions per minute for the shaft- 5 and about 200 revolutions per minute for the grinding cylinder will prove very effective. 1

hat I claim is:

1. In a device of the class described, acasing provided atone end with a feed opening, at its bottom a discharge opening, and

at the other end a second discharge opening zt-gri'nding cylinder mounted there n and communicating at one end with the feed openin with t e bottom discharge-opening, said cylinder being provided with an annular collar. at the dischergenend which collar is provided with a restricted annular opening, and. having an outwardly extending flange projecting into the discharge opening.

2. In a device of the cless described,'a rotary grindingl cylinder, :1 revoluble shaft provided with ammers mounted therein,.a

and by openings through its si'de's' casing surrounding said cylinder, a stationary end wall having an annular convergfiange, and a flan ed ring mounted upon said cylinder and aving an outwardly gared rim extending Within said annular an e. 3 7 IE testimony whereof I hereunto aflix my signature in the presence of two witnesses, this 24th dayof'August, 1911.
