Specification of Letters Patent.

useful Improvement in Rotary Cutters, of V which the following is a specification.
This invention consists in improvements in rotary cutters of that type which are used for reducing various matters to fragments.
The object of this invention is to provide certain improvements in the construction, form and arrangement of the several parts of a rotary cutter whereby the operation of the machine will be facilitated.
A practicalembodimentof my invention is represented in the accompanying drawings, in which c Figure l is a half front view and half vertical longitudinal section of the machine, Fig.
7 2 is a half end view and half transverse vertical section of the machine, Fig. 3' is a detail sectional view showing the adjustable lower half bearing for the rotary cuttershaft, Fig. 4 is a detail view showing the device which I employ for locking the cheek pieces against outward movement, and Fig. 5 is a detail view of the upper half of one of the end plates, which also includes the upper half bearing for the cutter shaft.
The rotary cutter shaft is denoted by 1 and it is provided with any suitable number of cutter heads 2, to which the rotary cutters 3 are secured. This rotary shaft is mounted between up er half bearings 4 and lower adjustable hall bearings 5, the lower half bearings being guided in their vertical adjust- Inents within recesses 6 in top plates 7 to which the legs 8 are secured. An adjusting screw 9 is provided for each lower half bearing 5, which adjusting screw passes through the top plate 7 and bears against the bottom of the said lower half bearing. A, casing is formed around the rotary cutters, which casing comprises a bottom screen 10, cheek pieces 11, 12, and end plates consisting of upper half sections 13 and lower half sections 14. The u perhalf sections 13 of the end plates are ormed integral with the upper half bearings 4 and the lower half sections 14 of the end lates are formed integral with the top plates 7. Bolts 15 serve to secure the upper half bearings, the top plates and the legs together, leaving the screws 9 free to adjust the lower half bearings.
A feed opening is left between the free ends .of the cheek pieces 11 and 12 and a hopper 16 is secured in position to direct the material to be disintegrated, to the cutters. This hopper is preferably made of sheet metal and is provided with a top hinged door 17 and a front hinged door 18. The front hinged door 18 is held closed by suitable latches 19. The cheek pieces 11 and 12 are provided with the usual stationary adjustable cutters 20. The cheek pieces 11 and 12 of the casing are hinged at 21, 22, to the lower half sections of the end plates. To permit these cheek pieces to be readily swung outward without dismounting the parts, the u per half sections of the end plates are provi ed with elongated slots 23, 24, o ening through the periphery of the upper hal f sections of the end plates and being concentric with the hinges 21, 22, of the cheek pieces] Bolts 25, 26, are located within the elongated slots 23, 24, and have their heads bearing against the outer faces of the upper half sections of the end plates so that when the bolts are screwed home the cheek pieces will be clamped rigidly to the end plates. To revent the cheek pieces from unintentiona ly spreading a art when subj ected to great strain, I provi e locking washers 27 which surround the bolts 25, 26, and are fitted to enter circular recesses 28, 29, at the inner ends of the slots 23, 24. When it is desired to release the cheek pieces, the bolts 25, 26, are unscrewed from the cheek pieces a suflicient distance to permit the washers 27 to be removed from their recesses 28, 29, thus permitting the bolts to pass outwardly through the slots 23, 24, as the cheek pieces are swung on their hinges 21, 22.
What I-claim is In a rotary cutter, a bottom screen, cheek pieces, end plates to which the cheek pieces are hinged, having elongated slots concentric with the hinges and opening through the 3 means for engaging certain of the bolts for my invention, I have signed my name in looking each of the cheek pieces to the end presence of two witnesses, this twenty-sixth plates to prevent ontward movement of the day of April 1907.
cheek pieces, said means comprising washers CHARLES F. BALL. 5 surrounding certain of the bolts and counter Witnesses:
