ADDICKS, F ROCKMART, GEORGIA DISINTEG-RA'IING MACHINE Application filed August 19, 1927. Serial No. 214,035.V

This invention relates to improvements in disintegrating machines of that type wherein a rotor, having a series of pivoted hammers, is used in conjunction with a breaker member disposed in a housing, the present invention contemplating a breaker member so constituted as to function as a feeder as well as a breaker for the material tc be disintegrated.'

The objects of the improvements are To provide a hammer mill without the use of the ordinary cage-bars which frequently become blinded by accumulations of materials, especially when the materials are damp, which interfere with the proper vdischarge of the ground product; to provide in a mill of the class indicated a series of traveling anvils in linked formation so disposed as to carry the material to be crushed into the range of the revolving hammers and sust-ain the material as it is broken by said hammers; and to so construct the machine that the material will be -forcibly fed into contact with the hammers and become discharged through an unrestricted outlet. l

These objects are accomplished by the construction illustrated in the accompanying drawings, in which Fig. 1 is a vertical section of a construction embodying the invention;

Fig. 2 is a partial transverse section of Fig. 1 on the line 2-2 thereof;

Fig. 3 is a fragmentary plan view of the breaker belt; and

Fig. 4 is a side elevation of the machine.

The characters appearing in the description refer to parts shown in the dra-wingsand designated thereon by corresponding characters.

The invention comprises a rotor 1 mounted upon adrive-shaft 2 which extends horizon- 10 tally through a housing 3. The rotor is of usual construction consisting of a series of discs 4 spaced apart and mounted concentrically upon the drive-shaft, so as to gyrate numerous hammers 5 that are arranged in groups, each group of hammers being secured upon a corresponding rod 6 that extends laterally through the series of discs. Y

Inthe housing are mounted a pair of shafts 7 and 8, each of which has mounted thereon a pair of sprocket- wheels 9 and 10 respectively, and upon said sprocket-wheels are carried a belt constituting a breaker member consisting of a series of anvil bars 11 linked together in successive order. Each anvil bar has made in its under side adjacent each end thereof a socket 12 in which the teeth v13 of said sprocket-wheels are received. vSaid breaker member is located in a slanting position with its lower portion extending beneath the rotor in close proximity thereto.

A pair of guides 14 for the upper portion of the belt composed ofthe anvil bars, are pivotally mounted upon the shaft 8, and in the lower` ends of which guides the shaft 7 is mounted, there beinga slot 15 in the housing through which one end of the shaft 7 extends, and which slot admits adjustable movement of said shaft 7 upon the'axis of the shaft 8.

` In the lower part of the housing is mounted a shaft 16, transversely disposed therein, and arranged to be longitudinally adjust-able, there being a bracket ,17 through which oney end of the shaft extends, and a nut 18 on the shaft for sustaining it in adj usted position.

Upon said shaft 16 are adjustably secured a pairof wedges 19 so disposed as to afford support for the guides 14, respectively adjacent the lower ends thereof, there being an opening 20 in each wall of the housing through which saidv wedges have movement,

and a corresponding seat 21. upon which the corresponding wedges are sustained.V Upon adjustment of the rod' 16, the wedges are moved so that the guides supported thereon are raised or lowered, and the breaker member accordingly` spaced relativeto the rotor.

The breaker .member belt is driven by the sprocket- wheels 9 and 10, and the shaft 8 upon whichthe sprocket-wheels 1() are fixed, is actuated by a transmission mechanism that includes a gear 22 on the shaft 8 that meshes with a pinion 23-on a countershaft 24,-which shaft has thereon a pulley 25 that is driven by la belt 26, the belt being actuated by a pulley 27 onvthe rotor shaft2.

The shafts? and 8, each extend through one of the walls of the housing and have mounted thereon upon their extending ends corresponding sprocket wheels 28 and 29 respecv tively, and upon said sprocket wheels is 109 Y ri'edtherebyinto contactwith the hammers,

the dog upon opposite sides thereof.v Upon:

adjustment of the screws, the sprocket wheel 28 may be advanced or retardedfso that the upper strand of the breaker member belt may be thereby slackenedy or"tigliten'ed` accord-r insha u A feature of theinvent'io'n consists'in the form of the breaker member which is'zcomposed ofthe linked anvil bars. Each bar is shaped so that its exposed outer f'aee iswinclined so that'its forward edge is elevated relative toits rear edge, whereby the breaker memberhas' a corresponding series of'offsets 35, that tend toV drag material that is .depositedv through the hopper 36'onto the belt, into contactwith thero'tor. Also, because of the inclinedfaces ofthe anvil bars, the material carriedV upon the breaker member tends to become wedged between the anvil bars and the rotor as the breakermember' progresses, so: that the material is subjected to' the action of the rotor with increasing pressure until VVdischarged from between' the lrotor and memberis" accordingly set in motion through the medium of the transmitting mechanism above described, so that the anvilbars are progressed in successive order downwardly inl the guides and beneath the revolving disintegrating member. The rock, or other material to be ground, is deposited through the hopper onto the breaker member, and is carwhereu on it is reduced to a pulverulent state by impl'ngem'ent between the hammers and breaker member. The pulverulent material is expelled through the outlet in the housing as v itpasses from the'disintegrating and breaker 'adjustablyvk shifting the wedges 19 inl the housing, the guides 14 are moved sothat the spacingbetween the breaker member and the disintegratingmember is varied and the 14 that extend beneath the rotor are ofarcuate form, so that the corresponding portion Y of the breaker member in passing through the arcuate portions of the guides partakes of corresponding curvature in concentric relation with the rotor, and in this manner the anvil bars are maintained, for a protracted period, inmore' or less uniform, proximity to the hammers, whereby the material passing between the rotor and breaker is subjectedto prolong-ed: action of the hammers which augmente the effectiveness of Vthe grindingoperation. What I claim is v13. In a' grindingv machine of the class described, a housing having an inlet and an outlet' opening; a roto'r'includinga multiplicity of hammers; a pair of guide members spaced apart'and positioned in the housing, the lower portions thereof being of arcuate form and extending beneath they rotor in concentric relation therewith; a breaker'member comprised of a series of transversely disposed anvil bars linked together inthe formV of an endless belt; a driving member comprised of a rotatable shaftmounted in the housing and having sprockety wheels fixedV thereon that have actuatingand supporting relation with the breaker member at oneend thereof ;v a secondl driving member comprised vof a shaft supported in said guides at the lower ends thereof and having sprocket wheels fixed thereon that have actuating relation with said b-reaker member at the lower end thereof; vadjustable supporting mechanism forV the lower portions of said 'guides; another sprocketgvvheel on each of said. shafts, one of which has means in connection therewith whereby it may be selectively advanced or retarded adjustably on its shaft; an endless chain connectingsaidlother sprocket wheels; an idler engaging said `chain for taking up the slack thereof and mechanism for actuating the first mentioned driving member. n
