UNITED Sfr-Ares PATENT Orrrcn.

EMPROVEMENT IN APPARTUS FOR PULVEFIZING PLUMBAGO, &c.
Specification forming part of Letters Patent No. 150,217, dated April 28, 1874; application filed February 12, 1874.
o all whom't may concern:
' Be it known that I, ROBERT ANDERSON, of
I Jersey City, in the county of lludson and State ot' N e w J ersey,liave invented an lmproven'ient in Pulverizcrs for Plumbago 'and other mineral substances, ot' which 'the t'ollowing'is a specification l 4Machines have been made for pulvcrizing mineral substances by a revolving' vessel containing balls or rollers; and revolving,- screens are also'connnon. My invention is for pulver izing plun'ibago or other mineral substances by a continuous crushing` and separating op eration, so that the particles will be retained until suiiiciently line to escape; thereby the machine is rendered continuous and uniform in its operation, but little attention is required,
' and the machine only has to be fed gradually with the material to be treated.
f I make use of a revolving cylinder or barrel, the staves ot' which are of metal, bolted firmly in place, and placed sutticiently close to allow 'y the escape ofthe pulverized material through the joint only when the said material is reduced to the required tinencss. The plumbago or other mineral is supplied, at .one end, in a regulated quantity, and acylinder or conoid lwithin'the barrel rolls upon its inner surface sect-ion, and Fig. 2 is a crosssection, ot' the said pnlverizer; and Fi 3 is a detached view of one stave and a conoid pulverizcr.
,The heads ul are provided with the gudgeons b and c, set in bearings d at the ends of the re,
ceptacle e; and f f are the metal staves, connected to the heads a a rmly, and they are lset more or less closely together, according to the iineness of the material that isrequired from the machine. One of the journalsbis tubular, in order that the plumbago or other` mmeral substance maybe fed into the bairel or cylinder with uniformity from the hopper l and shoe k, or other convenient ineans.-
The' staves maybe straight, as in Fig. l, or
curved, as in Fig. 3; and the cylinder' or con- 'oid l within thel barrel acts as a crushing and pulverizing roller, asthe barrel is revolved by competent power applied to the pulley fm, 01' otherwise. This roller l alsov jars thel staves, asit rolls off one upon the next, and g1ves sut cientvibration to shane out the ne partwle'b of ground mineral matter that pass through 4the crack or opening between one stave M111 the next. l
The material to be ground should only be supplied as fast as it can 4be thoroughlyl Pulverized, in order that the metal roller may press' directly upon the inside of the cylindei` I I claim as my invention- The pulverizing apparatus, made of two heads, united by metal s taves, and a roller within, substantially as set forth, whereby the finely-ground material is passed away between the staves, as specified.
- Signedby me this 7th day of February, A.'
