Abstract: 328,684. White, A. E., (Lovell Manufacturing Co.). Feb. 4, 1929. Wringers, pressure and rollerseparating arrangements for.-The bearing blocks 11, Fig. 1, of the shaft 10 of the upper roller 9 are acted on by a bow spring 12 which is carried by a recessed cylindrical block 27 having a cam 28 on its upper rim. A second cylindrical block 21 fixed to a handle 28 is provided with a cam 29 on its lower rim and is rotatable about a stem 24 having a. head 25, Fig. 2, at its lower end for retaining it within the recess 26 in the block 27. The block 21 is also provided with projections 22 which coact with ears 20, Fig. 1, on the under side of a plate 16 fixed to the cover 13. Diametrically opposite recesses 17 are formed in the plate 16 and integral housing 15 so that on a quarter rotation of the block 21 from the position shown, the projections may pass therethrough until they abut against the upper wall of an annular opening 18 in the housing 15. Upon a further quarter rotation of the block 21 the projections 22 can be passed upwardly through openings 19. Two stages of pressure may thus be applied to the rollers, namely, that in which the cams 29, 28 are out of register or that in which the cams are in full engagement as shown, the projections 22 being engaged under the ears 20 in both cases. In a modification, not shown. the central portion of the bow spring is bolted to the top frame, the lower cylindrical block is dispensed with and the other block is rotatable about the bolt and is provided with two pairs of diametrically opposite projections, each pair being spaced longitudinally along and radially around the block. Each bearing-block 11 is carried by a stirrup 36 having slots 37 at its upper ends through which a pivot pin 31 passes, the pivot pin extending between the two side walls of the hollow cover 13. Two latches 30. connected by a bridging member 34, are mounted on the pivot pin and engage recesses 33 in the hollow side members 1 of the frame to secure the ccver thereto. Upon the ends of the spring 12 rising sufficiently, the bridging member 34 is struck thereby and the latches are released from the recesses 33 thereby freeing the cover and permitting its removal or the separation of the rollers to any desired extent. A tail piece 35 on the bridging member 34 by engaging the cover prevents jamming of the latches when reassembling. The bottom member 2, Fig. 1, of the frame is of inverted channel form. The meeting edges of its sides and top are slit near the ends of the member and the top is bent upwardly at each end as shown at 4 to engage the inner inside faces of the hollow side members whilst the sides 3 of the bottom member extend along the outside of the bases of the side members and are secured thereto. The upper ends of the portions 4 are bent over as at 5 to form supports for the bearing blocks 6 of the lower roller shaft. Wringer-boards.-The drip boards 38, Fig. 2, are carried by a central member 39 secured to posts 44, Fig. 1, having slotted feet 45 by which they may be removably bolted to the bottom frame 2. A tilting trough 40, Fig 2, pivoted on the pins 41 by which the member 39 is secured to the posts 44 is held in either position by a spring 42 engaging a dependent detent 43. On release of the nut 48, Fig. 1, the whole unit may be removed from the wringer frame.
