' This invention pertains to apparatus for reducing and cleaning cullet or waste glass preparatory to re-use. The invention 1s perticu arly applicable to reduction of wlre-reinforced cullet, from which the wire must be removed to obtain a usable product.
In the reduction of waste glass it is also desirable to control the grade or size of the product,. and the crushing or breaking uparatus should be adapted for producing t e desired result. Excessive reduction should not occur as that produces obj ectionable glass dust and fine wire particles which do not respond readily to magnetic separation.
The least objectionable apparatus heretofore used has been a pair of closely spaced rolls between which the cullet is passed, but that apparatus does not produce a satisfactory product because it is impossible to maintain uniform thicmess of material being fed to the rolls. The thick portions of the material receive the full ressure of the rolls, forcing them apart and permitting thinner portions of the material to pass through untreated. As a result, in the case of wire glass it is necessary to pass the cullet through the .rolls several times in order to suficiently free the glass from the wire. The rolls must exert revious machines.
high pressures and be composed of special expensive material to resist excessive wear.
Various kinds of jaw crushers and high a so been trie but none has been acceptable. They pulverize the glass too much, are heavy and expensive, and require excessive power to o crate them.
A 1 machines of the roll or crusher type attack the glass by compression, against which the glass is very resistant, consequently great power is required to operate them.
The principal object of the present invention is to overcome the shortcomings of This is done by a modication of the roll principle in which the cullet is broken up not by compression but principally by impact, against which glass has little resistance.

view of the apparatus, on
In general, the apparatus comprises a pair of parallel rotating drums carrying impact devices which. are here shown as rollers supported by the drums and projecting through the cylindrical surfaces thereof. The glass to'be crushed passes between the drums and is broken up by the impact rollers.
Each drum is made up of a number of disks 10 placed side by side on a square shaft 12. The ends of shafts 12 are turned as at 14 to provide bearing surfaces, and the bearings 16 supporting the upper drum are adjustable b handwheels 18 and screws 20 passing throng frame 22 so that the distance between drums may be varied if desired. In practice it has been found advantageous to set the bearings so there is approximately inch clearance between the impact rollers of the two 1 Each disk 10 is provided'near its periphery with a pluralityof integral trunnion ins 2a, upon each of which is mounted a ring-like roller 26 having a bore 28 somewhat larger than the diameter of its trunnion 24: so that the roller has considerable freedom of motion on its trunnion. When disks 10 are mounted on their shafts, the ends of trunnions 24 are against the back surface of the adjacent disk or against an end plate 30, thereby limiting the endwise movement of the rollers on the trun'nions. Around the rim of each disk 10 tend to prevent glass entering the interiors of the drums past rollers 26 and also serve to prevent a roller being thrown out of its drum in case its trunnion should break.
As may be seen in Fig. 2, the backs ofall 109 disks forming the upper drum are toward the left and those of the lower drum are toward the right. The disks are so pro ortion that the above arrangement places t e rims of theopposing hammer rollers 26 of the two drums into a slightly overlapping relation-' ship, as may best be seen at the middle of Fig. '3. This is found to be a particularly advantageous arrangement for producing the desired results.
The apparatus is preferably arranged in practice somewhat as shown in Fig. 1, with the, lane of the shafts inclined at an angle of a ut 45. By means of chain 34 and y gears 36, 38 en aging gears 40, 42 on upper and lower sha s 12 res ectively, the drums are rotated as indicated y arrows in Fig. 1, their adjacent surfaces traveling in the same direction but preferably at different speeds.
In the machine illustrated, each disk has six rollers angularly spaced sixty degrees apart. Shafts 12 are square, and when the disks were placed on the shafts to assemble o the drums, each disk was turned ninety degrees relatively to its neighboring disks, the result being that the rows of rollers lengthwise of the drums are spaced angularly thirty degrees apart.

Material is fed by chute 54 across anvil 56, where it is broken u by hammer disks 58 of roll 50. The brea ng action is continued between disks .58 and screen 60, which forms the bottom wall of the housing surroundin the crusher. Material not passing throug the screen is carried up between the rolls where it receives treatment similar to that described in connection with the machine in Figs. 1 and 2. Any material carried over the tops of rolls 50, 52 is treated between disks 58 of roll 50, disks 62 of roll 52, and the upper and end walls of the housing,
