To all whom it may concern:

Be it known that I, EMANUEL J. PERRY, citizen of the United States of America, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

The invention relates to improvements in washing machines;

It is an object of the invention to provide a washing machine having a washing cylinder therein, which may be swung from the casing to permit a discharge of clothes therefrom that have undergone a washing treatment.

The invention more particularly aims to provide a washing machine with a movable clothes containing cylinder, which may be shifted from the machine by power means to expeditiously permit the clothes to be removed.

From a more specific aspect, the invention comprehends a power washing machine, wherein the washing cylinder is connected with swinging arms attached to the casing, which arms are shifted by power cylinders to lift the cylinder bodily from the casing upon the completion of a washing action to allow the clothes to rapidly drop from the cylinder, thereby saving the excessive time generally heretofore employed in removing clothes from the older types of washing machine.

In the accompanying drawings I have disclosed the preferred embodiment of the invention, but this disclosure is made for the purpose of illustration only, and the construction and arrangement of the parts are subject to many changes without departing from the invention.

In the drawings Figure 1 represents an end elevation of one end of the washing machine; and,

Fig. 2 an end view of the machine, with the clothes cylinder in an extended position.

Referring now more particularly to the drawings, wherein like reference characters indicate corresponding parts, the numeral 1 designates the casing of a washing machine,

which may be of any preferred or conven-' tional structure, the same being shown as being supported upon the legs 2. The casing of the washing machine is provided with a movable segment section 3, hinged to the main portion of the casing by the hinge 5, said segment carrying a part of the bearing 6, .for a purpose which will hereinafter appear.

Mounted within the washing machine is the washing cylinder 7 This cylinder may be of the usual open work construction, or any other desirable form, being supported upon a shaft 8 carrying a gear wheel 9 that meshes with a gear 10 driven by a pulley 11 carried by a suitable shaft, and operated from any source of power. The cylinder normally is maintained within the washing machlne, as disclosed in Fig. 1 of the drawlngs, at which time the segment section 3 is closed, and the shaft 8 is resting upon the bearings l2,it being understood that steam. or water is introduced to the casing 1, and the cylinder revolved for cleansing a supply of clothes placed therein through the movable door 13. This construction is all common 1n the various washing machines now in use.

Considerable time is generally lost in removing a supply of clothes from a cylinder after a washing action, it having been the practice to rotate the washing cylinders to a point where the door could be opened, and to then open a door in the casing and remove by hand the supply of washed clothes. This has required much time and labor. and it has been appreciated by those skilled in the art that a simple and eflicient mechanism for controlling the washing cylinders whereby 'a supply of clothes could be expeditiously removed and anew supply placed therein, would be a marked advance in the art.

The present invention, therefore, aims toprovide a mechanism for rapidly shifting the cylinder from the casing so as to enable clothes to be removed therefrom. To this end I employ a pair of swinging arms 14, one being disposed at each end of the casing, which arms are mounted upon a shaft 16 connected with the casing at one end, and at their opposite ends pivotally engage the cylinder shaft 8. Connected with these arms at a point near the shaft 8, are the piston rods 17 carried by pistons 18 movable in the fluid pressure cylinders 19, which are pivoted at a point 20, and receive a source of fluid supply through the pipe 21. This fluid supply maybe water, steam or any equivalent energy, and is introduced to the cylinders 19 for the purpose of reciprocating the pistons therein. While I have disclosed a cylinder as positioned at each side of the machine, it may be understood that a single cylinder maybe employed, or other power devices may be usedfor moving the arms 14, in a manner which will be now described.

When a fluid pressure is introduced to the cylinders 19, the pistons are caused to reciprocate and swing the. arms 14 upwardly to the position disclosed in Fig. 2. To open the segmental section 3 of the casing .1', when the cylinder is to be moved from the casing, link arms 22 are employed, said arms being pivoted tothe arms 14 at one end, and at their opposite ends being pivoted to brackets 24 connected with the segmental section 3. It will therefore be apparent that when the arms 14 are raised through the agency of the fluid pistons, and their cylinders, the segment 3 will be swung on its pivot '5 and the entire shaft 8 carryingJ its washing cylinder and operating gear 9 odily lifted from the casing 1, to the position shown in Fig. 2. The cylinder is maintained in this position until the clothes have been removed from the opening therein, controlled by the door 13, whereupon a new supplyof clothes may be introduced to the cylinder, and by exhausting the fluid pressure in the power cylinders 19, the washmg cylinder 7 will be again lowered to the position shown in Fig. 1, the segmental section 3 of t e casing 1 being closed so that the section6 of the bearing carried thereby will engage the shaft 8.

It has been found preferable to provide a means for lockingthe cylinder 7 with respect to the arms 14 so-as to prevent a relative movement of the cylinder when a supply of clothes has been washed, and it is desired to shift the washing cylinder from the casing. To this end, I provide a latch 25, whichis mounted upon one of the arms 14, and is formedwith separated engaging sections, adapted to be drawn toward each other upon a manipulation of the handle 26 for the purpose of locking the gear 9 carried by the shaft 8 to one arm 14. This lever 26 is actuated when the clothes in the cylinder have been washed, and the gear is locked when the cylinder is in such a position that the openlng controlled by the door 13 will be in the position shown in Fig. 2 when the entire cylinder is shifted from. the casing. In other words, the cylinder is preferably locked when the same is to be shifted from the casing so as to be in a position to most favorably discharge the cleansed clothes. While a locking means is preferable, it is not entirely essential,.and the same may be dispensed with, should this be desirable; It will likewise be a .parent that any other type of locking mec anism may be employed suitable for accomplishing the desired purpose.

tion of the bearing for the shaft 8, it is .otally mounted upon pins 28.

preferable that a means be employed for locking this movable section to thecasing 1 when the same is in operation. I have therefore shown swinging latches 27, one at each side of the movable section 3, and piv- When the machine is to be operated, the latches are swung over pins 29 carried by the body 1,

and serve to rigidly hold the section 3 in a closed position and against accidental displacement due to the rotation of the shaft 8. Obviously, other fastening devices may be used, and I have merely shown the present type of fastener as a convenient means of retaining the section in a lowered position.

Having thus described the invention, the

operation may\be briefly stated as follows:

Assuming that a supply of clothes has been introduced to the cylinder 7, and the movable section 3 lowered to the position shown in Fig. 1, the pulley 10 is then'operated by a belt or any other source of power, rotating the gear 9, which correspondingly rotates the cylinder 7 within the casing. Water or steam is present therein, and the rotation of this cylinder for a sufficient,period serves to cleanse the clothes contained therein. After the clothes have been washed the latches 27 are swung to the position shown in Fig. 2, and the lever 2.6 shifted'to lock the cylinder 7 against movementrelative to the arms 14. Fluid pressure is then applied to the power cylinders 19 through the feed pipes 31, serving to raise the pistons therein, which pistons, through the piston rods 17, raise the arms 14, which arms lift the shaft 8, and its cylinder 7 from the casing to the position shown in Fig. 2. It will be understoodthat as this cylinder is being moved from the casing, the link-arms 22 also move the segment 3 on its pivot 5 so as to provide a space for the passage ofthe shaft 8. The door 13 is opened when the cylinder is in the position shown in Fig. 2, and the cleansed clothes removed. A new supply of clothes is then introduced to the cylinder and the fluid pressure in the power cylinders 19 exhausted, which causes the washing cylinder to again move into the casing 1', as shown in Fig. 1. The arm 26 is then actuated to release the gear 9, and the swinging latches 27 are shifted so as to engage the pins-29 and lock the'segment 3 in position. After the clothes are washed, the operation herein described is repeated, as will be clearlyunderstood.

Having thus described the invention, what I claim; is: a
