WASHING AND DRYING MACHINE Filed Sept. 4, 1952 3 Sheets-Sheet 5 I INVENTOR GEORGE MARKOVICH m 7 fl ATTORNEY Patented Sept. 15, 1953 UNITED STATES PATENT OFFICE WASHING AND DRYING MACHINE George Markovich, Akron, Ohio Application September 4, 1952, Serial No. 307,754

cleanse rubber, plastic, or metallic objects or" manufacture. Such washers are subject to rapid deterioration of their cylinders in the solvents or caustic solutions in which their parts operate.

A principal object of the invention therefore is to provide a washer and drier having interchangeable cylinders so that the drier cylinder can be used in the washer and vice versa. The washer cylinder being subject to corrosive fluids is most likely to wear out first and by using the drier cylinder as a replacement for the washer cylinder for some particular solvents or acids, the use life of the two cylinders can be apprecrably extended.

A further object and advantage of the inven tion is the provision of identical cylinders or barrels in the washer and drier units so that fewer parts are needed and ease of manufacture or repair is assured.

A still further object is to provide a horizontally rotating cylinder in the washer unit which issuspended at or near its middle and center of gravity, and may be tilted to discharge while still rotating without loss of speed or cessation of rotation, which causes wet or degreased parts to stick and spot each other before reaching the drier.

A still further object is to provide a hydraulically driven tilting device for both the washer and for the drier, and one of simple and inex pensive construction and maintenance.

These and other objects and advantages of the invention will become apparent by reference to the following drawings in which:

Fig. 1 is a plan View in elevation of the washer and drier of this invention, with portions in section.

Fig. 1a is an end view in section taken on line la la of Fig. 1.

Fig. 2 is a plan View in elevation of a portion of the washer-drier with the loading and discharging doors in open position.

Fig. 3 is a detailed view in section of one end of the washer or drier cylinder in position extended out of the end drumhead to show the construction.

Fig. 4 is a detailed sectional view on line ti of Fig. 2.

Fig. 5 is a sectional View on line 5-5 of Fig. 1.

3 Claims. (Cl. 51164) Fig. 6 is a detailed plan View of the main support of the washer cylinder, and

Fig. 7 is an end view of the tub of the washer showing its three supporting legs.

Referring to the drawings, in which like numerals indicate like parts throughout the several views, in Figs. 1 and 3, the washer is is shown composed of end drumheads H and 12 on axle l3 which is shown to be held against sidewise or endwise movement in posts 14 and it by means of the groove l6 cut therein, shown more clearly in Fig. 4. Stops H and [8 on posts it and i5, respectively, are provided to limit the upward movement of washer I0 and to keep it level.

A central support post l9, depending from the ceiling 2| or other overhead support has within it a hydraulic ram 22, the end of which is formed as a clevis 23 (shown in Fig. 6) in which is pinned swivel 24. In Figs. 1, 3 and 5 it will be seen that frame members 25, 2G, 21, 28 and 28 extend the distance between drumheads i i and i2 and form supports therefor, members 25 and 26 also forming the supporting bed for motor 3! and reduction gear 32 which by means of spur gears 33, 34 and chain 35 drive the axle i3. Loading bucket 36 is here illustrated to show the relative position of the feed port 37 in drumhead ii. A stop 38, bolted to member 25 holds the bucket .36 from side sway. Members 25 to is form an outer cage for the washer and provide a support on their inner sides for bearing ring 45 as seen in Fig. 5. Bearings 42 bear on support ring it which in turn is secured to and supports screen 44 on rods 45. Diagonal braces it are bolted to collar 40 and secure the axle iii to the end rings 41 and 48 which rotate in groove t9 (Fig. 3) and lend endwise support to the end rings ti and. 48. It will be seen that braces 4E coincide with certain of rods 45, adding strength to the washer cylinder 50 as formed by the screen it and other parts as set forth above.

The identical construction is followed in the drier 5!, with the exception of the bearing ring 4|, bearings 42 and support ring 53, which is a unit in itself and is readily attached to rods 35a of the cage of the drier 5|. Axle lSa of the drier differs also, being shorter and being supported at end 52 in a socket 53 formed in the tub end 54. Tub 55 of the washer i0 is of conventional semi-cylindrical shape having a water inlet 58, a drain 56 and steam coil 51 also of conventional design. Leg 6| supports the other end 62 of the drier 5| on a similar hydraulic ram 63, permitting the drier to be lowered for discharge of its contents as will hereinafter be described.

The drier portion 5i of this invention has a similar motor 31a and reduction gear 32a similarly supported on the frame members 25a, 26a. Surrounding the drier is housing 65 having exhaust fan 66 and a source of heat, here shown as a row of infra-red bulbs 61 which provide heat to the articles in the drier As will be seen in Fig. 2 the loading door 68 is hinged on drumhead H and is operated between open and closed position against port 31 by bydraulic piston 69, and an unloading door or gate on drumhead l2 falls between chute sides H to lie on top of door 12 which is hinged down-, wardly from the drumhead I la of drier 5|, which door 12 is similar to and replaceable with door E8 of the washer, and has a similar hydraulic piston 69a. An unloading door or gate 10a is hinged on drumhead l2a of the drier and is similar to gate 10. Spur gears 33a, 34a, and chain 35a are also I interchangeable with the same parts on the washer It, and require only clamping on the axle 1311 to use either of cylinders 56 or 51 in the washer position. In Fig. 7 it will be seen that the tub 55 has two central posts [4 and 59, the latter having the socket 53 for axle 13a and a half-bearing T3 for axle l3.

In operation the hydraulic ram 22 raises or lowers the cylinder 50 While the motor 3| turns the cylinder. Swivel 24 permits the cylinder of the washer to tip downwardly at the discharge end, or to permit the whole cylinder to swing to unload into another conveyor. The loading doors 68 and 12 of the washer and drier operate by the ram 63 and piston 69 respectively and the chute sides ll of the drier clear the axle [3 of Washer as it is lowered or raised, the door 1i] being raised for its passage.

The advantages of the interchangeable cylinders are believed to be obvious, and while the screens and cylinders may be constructed of wire cloth, plastic, or other materials to the best of advantages, it is to be understood that the invention is not to be limited to those materials but other materials and various modifications may be used and practiced without department from the spirit and scope of the invention.
