DEVICE FOR MANIPULATING DRUMS 0R CYLINDERS.

Application filed my '10, me.- Serial no. means.

To all whom it may concern:

' Be i known that'we, MICHAEL E. DALY and EDMUND I. CUTT R, citizens of the United States, residing at Cincinnati and Norwood, respectively, in the county of Hamilton and State of 'Ohio, have invented certain new and useful Improvementsin x -Devices for Manipulating Drumsfor Cyllnders, of which,

tion. p v This invention relates to attachments for v washing machines and tumblers and conthe-following is a specificateinplates mechanism. for rotating the drum.

' or'cylinde'r to openposition and holding it in such position.

' In tumblers used'for. treating. fabrics and in washingmachines and other similar devices for treatin fabrics drums are utilized for containing abricsduring their treat,-

' ment and these drums are usually provided with a suitable door by means of whlch access may be had to the interiorlloft'he drum or c li'nderl "These drums or cylinders usual yrotate-intermittently in both direc- 25. tions. within a suitable casing which is pro-,

vided with a door and when it is desirable to obtain'acoessto' the materials it" often I happens that the door of the drum or cylinder is not oppositeto the door of the casing, requiring the'rotation of the drumor cylinder until itsdoor is. in registry with the door ofthe casing. It is also essential in.

these devices to hold the drum or' cylinder against rotation wh le the doors are open to prevent injury to the operator and to prevent injury tothe apparatus itself.

The present invention is devised to provide simple and efficient means for rotating -thedrum by hand, for locking it in the proper position and for. locking the man- 'ually operable means for rotating the drum out of position'so that itmay not engage any of the parts during'the operation of the machine. 1 1 a The invention will beset forth more fully in the following specification, drawings and claims. j,

Referring-to the drawings, Fig.1 is an end elevatlon of a washing machine provided with the device; Fig.. 2 is an enlarged detail view of the device in elevation; Fig. 3 is a'section at A. of Fig. 2; Fig. 4 is a front detail elevationof the. device with the parts in the positions which they assume when in operationrFig. 5 is a similar viewwith the parts 111 the same position but with the lock withdrawn; Fig. 6 is a view similar to Fig.

5 but with the drum driving gear out of mesh with the drum gear; and Fig. 7 is a view similarv to Fig. 6 with. the lock in position-to hold the riving'gear out of mesh.

In the arrangement shown in the drawings lrepresents the main casing of a washing machine supporting a main drum shaft 2 which receives the drum and thedrum driving gear 3, the drum being within the casing and not requiring 'any particular description; The gear 3'is driven from a-suitable shaft 4 in any suitable manner (not shown). The mechanism. alrea dy' described is of any. preferred construction and is only set forth in a general way to furnish a clear understan'din basis for com ination claims.

. The handattachment for the manipulationof the drum forming the subject matter of this invention comprises a base secured to the casing 1 and including asupport or base plate 6- provided with a boss 7 rigidly supporting a shaft 8. Rotatably mounted upon this shaft is a tubular gear member 9 provided with a pinion 10 adapted, when in proper position, to mesh with the gear 3. The tubular. member 9 isfurther provided with a suitable lever 11 having a handle12 at the end thereof. Theouter end of-the shaft 8 receives a cap screw 13 engagin a washer 14 which holds the tubular mem er 9 upon the shaft. The tubular member 9 is free for end-wise movement upon the shaft of the device and to form a- Above the shaft 8 the ,base 6 is provided I V with an outwardly extending arm 17 having a bearing 18 adapted to receive a'shaft 19 upon which is mounted a weighted lever 20,, a gear dog 21 and an oppositely extending trip 22. The gear do 21 is provided with a suitable notch in icated at 23 in Fig. l and adapted to receive a tooth of the pinion 10 when in proper position. The gear dog 21, trip 22 and weighted lever 20 are all'arranged upon the shaft in a manner to produce the following results, to wit, that when the weighted lever is thrown to the right of the shaft, the gear dog has a tendency to move down toward the mion 10, but when the weighted lever 20 is t rown result of itis clearly shown inFig. 6.

v The normal'positionof the device when the machine is operating is that shown in Fig. 7 which is one wherein the pinion 10 is out of mesh with the drum gear 3- and the gear dog 21 is in engagement with the sleeve 15 and behind the pinion, thus preventing it from bein moved into mesh with the drum gear. en the operator wlshes to use the manual attachment, however, he

grasps the weighted lever 20 and shifts it in a counter-clockwise direction untll the gear dog is free of the teeth of the pinion 10. The pinion 10 may then be moved into mesh with the drum gear, allowing the latter to be freely rotated by hand until the door is brought in o the d si POSitiOII- Wheni trollin said driven member and comprisin this operation has been completed the weighted lever 20 is then moved toward the position shown in Fig. 4 when the notch in Fig. 7, when the inder having a driven member,

the gear do may be made to engage one of the teeth 0 the pinion 10, thuslocking the pinion and the drum gear against operation until the "gear dog is removed. The operator' may then disengage the pinion by moving the wei hted lever 20 from the position shownv in ig. 4 to'that shown in Figs. 5 and 6, "when n sequence the pinion will be released and the trip 22 will engage the flange and move the pinion 10 out of mesh,

. the parts being thenin'the position in which they are'indicated in Fig. 6. The operator then, as a safety measure, shifts the weighted lever back into the position shown in ar dog will rest upon the sleeve'back of t e pinion 10 and thereby prevent its engagement with the drum gear' until raised. I

What we claim is: f t I I 1. The combination with a drum or,cylin der having a driven member, of manually operable mechanism for operating and controlling said driven member and comprising a driving member movable into and out of engagement with said driven member, and a unitary device adapted in one position to lock said driving member when in operative position and adapted in another position-to prevent re-engagcment of said drivmg member when it is out of operative position.
