WASHING-MACHINE.

Specification of Letters Patent.

Patented June 28, 1910.

Application filed July 28, 1906. Serial No. 328,247.

To all whom it may concern:

Be it known that I, HENRY S. JUDD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Washing-Machines, of which the following is a specification.

My invention relates to washing machines.

The object of my invention is to provide a washing machine efficient in operation and not liable to get out of order.

My invention consists in a number of features which will be readily apparent as the specification proceeds.

Referring to the drawings, Figure 1 is a front, Fig. 2 a front central sectional, Fig. 3 a plan, and Fig. 4 an end central sectional view of the device of my invention. Fig. 5 is a front and Fig. 6 a side, partially sectional, detail view of the hook for supporting a spring. Fig. 7 is a sectional side view, and Flg. 8 is a sectional front view of the pivotal device for the bottom of the springs. Fig. 9 is a bottom view of the plate on which the device of Figs. 7 and 8 bears. Fig. 10 is a perspective detail view of the knife edge bearing nut of Figs. 7 and 8. Fig. 11 is a detail view in elevation of the swinging wringer-board or block. Fig. 12 is an enlarged fragmentary view in perspective showing the construction of the gasket employed to prevent leakage between the vessel and its lid or cover. Figs. 13 and 14 are sectional views of the same illustrating the manner of assembling the parts.

Again referring to the drawings, I provide a washing machine body or vessel, hava front wall 15, rear wall 16, side walls 17 and 18, bottom 19 and top 20, of the general type shown in my prior application. Extending from the front and rear walls 15 and 16 are short trunnions 21 and 22, journaled in brackets 23 and 24:, which are suitably mounted upon vertical supports or standards 25 and 26. These vertical supports are rigidly secured to the base of the machine, which consists of front and rear members 27 and 28 connected together by a central cross-member 29.

In order that the operator may give the vessel such motion, I provide upon the top of the device suitable upright supports 85 carrying handles 36 adapted to be grasped by one or more persons to facilitate carrying the machine around. In order to put soiled clothes into the vessel and to retain the water therein during the washing process, hinge to the top 20 at 39 a suitable cover 40 adapted to close the opening in the top 20 through which clothes may be inserted into the machine, this cover being normally held in closed position by the button 11, or other suitable detachable securing mechanism. For convenience, I provide a handle 42 which the operator may grasp to tilt the cover 40 upon its hinges 39, to open the vessel. In order to insure this cover 10 fitting sufliciently tight in the opening provided for it, so that water within the machine will not leak out around the edges of the cover during the washing operation, I provide a special form of gasket which is illustrated in detail in Figs. 12, 13 and 14. This gasket may be upon the edges of the cover itself or upon the inner edges of the top 20 of the vessel, the latter being the construction illustrated. I run a channel or rabbet 15 in the edge of the part which is to have the gasket, and over this I lay a strip or preferably two of packing 4a which should be of felt or other similar fabric, although rubber might be used. The latter, however, is not so desirable as it is susceptible to the action of hot-water and soap, and is apt to rapidly deteriorate. I then lay a strip 15 preferably of wire upon the packing and drive both strip and packing home to a bearing in the channel, where it is subsequently secured by staples or other fastening devices 46. The packing used is wide enough so that when in final position, the edges project considerably for the purpose of crowding against the adjacent surface of the other part of the vessel. By this construction there is a double packing, so to speak, one for each edge of the strip and moreover the packing when worn may be readily removed by merely withdrawing the staples and lifting out the retaining strip. This door 40 is provided with vents or air and steam escape openings 50, and a protecting corrugated plate 51, such as is shown and described in my prior application before referred to.

In order to allow the water within the machine to readily pass through the meshes or fabrics of the clothes to thereby mechanically remove the dirt contained in them, I provide within the machine a plurality of slats 5 1 separated from each other, as shown in Fig. 4, so that there are spaces 55 between them extending entirely around the interior of the machine. These spaces afford passages for the water which has passed through the clothing supported at any point within the machine upon these slats. In order that the clothing may be held in fixed positions upon the slats, so that the water may pass through it, I provide the interior faces of these slats with notches 56 against which the clothing may engage. Similarly, to hold the clothing in suitable positions upon the front and rear interior faces of the machine, I provide in said front and rear walls suitable corrugations or notches 58, as shown. These slots also direct the flow of water and prevent endwise circulation which tends to twist the clothing when long articles are in the machine.

In order to assist the operator in oscillating the machine body or vessel, I secure to one side wall 15 of the machine a suitable casting 60 having an arm 61 depending below the bottom of the vessel at the right of the center line A A thereof, and olf-set toward the front frame support 26, as shown in Fig. 4, and upon the other wall 16 I secure a corresponding casting 63 having an arm 64 depending from the bottom of the vessel at a distance to the left of the center line A A equal to the distance which the said arm 61 is to the right. This arm 64 is, as shown in Fig. 4, off-set toward the rear vertical support 26, an amount equal to the off-set of the arm 61, as heretofore described. The off-sets just described are, as will hereinafter more clearly appear in the description of the operation, provided so that the springs controlling the vessel will entirely clear the vessel as it oscillates. The springs are wholly outside the path of travel of the tub and below the tub.

On the bottom of each depending arm 61 and 64 is a horizontal lug 67, as is best shown in Fig. .6, machined to receive a suitable bushing 68 of less width than the width of the lug 67, as shown in Fig. 6. Journaled upon this bushing 68 is a hook of the same or slightly less width than said bushing and of perceptibly less width than the lug 67. Through the depending arm lug 67 I secure a rivet or bolt 7 2 adapted to secure a washer 73, in the posit-ion shown in Fig. 6, against lugs 67. This washer is, as shown, of a diameter sufiicient to engage and hold in position both the bushing 68 and the hook 70, but these latter two members being of less width than the lug 67, there is no binding action by the washer upon them, therefore they are free to rotate upon the lug 67 as a pivot. Each hook 70 is provided with a notch 7 5 in which the upper loop 76 of a retractile spring 77 is adapted to rest. The object in thus providing a special articulate joint and interposing it between the lug 64 and spring 77, is to eliminate the constant bending or working of the loop which would occur if said loop were hung directly upon said lug. Ithas been found by experience that such bending or working does occur when the connection is made direct and results in a crystallizing of the spring and ultimate fracture. With my hook, the movement takes place between the lug and the hook, and as the parts are machined, the operation is especially smooth and the life of the spring is indefinitely prolonged.

By having the arms 61 and 64 off-set at opposite sides of the central transverse plane of the machine, as shown, I obtain a tension upon the vessel upon opposite sides of such plane, thereby steadying and stopping the vessel in a fixed position; whereas, when the springs are attached directly in the central transverse plane, there is no such steadying action.

Extending from the lower end of each spring, 77, is a rod 80, of a length suflicient to reach substantially to the ground, screwthreaded in its lower end 81 for receiving a nut 82 which has upon its upper face knife edges 83, as best shown in Figs. 7 and 10. The cross-bar 29 of the base-frame has upon its bottom a metal plate 85 apertured at 87 for the passage of rods 80,'and having at proper places notches 84, in which said knife edges 83 are adapted to bear. The body of the cross-bar 29 has cut therein below each depending arm 61 and 64, U-shaped recesses 89, registering with apertures 87 as best shown inFigs. 1, 2, and 8. Rods pass through them to reach the apertures 87, and are adapted to oscillate backward and forward crosswise of the machine, bearing dur ing said oscillation upon the knife-edges 83, as described. As heretofore stated, the'arms 61 and 64 are off-set so that the springs 77, entirely clear the side walls of the machine, so far as interference by the springs with any part of the vessel is concerned, it may rotate in a circle. In other words, the oscillation of the vessel is not interfered with by the springs, as is the case with the machine of my prior application.

By locating the knife edges 83 at the low est possible point, as described, the machine has a greater length of swing without stretching the springs beyond the points to which they would be stretched, were they mounted higher up. It is desirable that the points of connection of the springs to the frame be such that a line through said points of attachment is parallel to the axisof osoil lation of the vessel. This construction is best illustrated in Fig. l in which the machine is viewed from the side and the two springs seem to meet at a point.

In order to limit the movement of the vessel and assist in its return to normal position with the least possible tension upon springs 77 I provide bufier blocks 91 carrying buffer springs 92 adapted to be engaged by stop blocks 93, when the machine has been rotated from the full-line position of Fig. 1 to the dotted line position of that figure. This limits the arc of rotation of the machine to approximately 180.

In order to provide for a wringer which may be used when the machine is, not being oscillated, and may be moved out of the way when the machine is in operation, I hinge at 95, upon the vertical support 25, a plate 96 carrying a wringer board or block 97 secured at an angle thereto, the relation of the parts being such that when they are moved from the full line position of Fig. 4 to the position of Fig. 11, the board 97 is in upright position as there shown (also in dotted lines in Fig. 4) so that a wringer secured to the block 97 is in proper position at the side of the machine to be used for the purpose of wringing clothes. Ihis board 97 resting upon the top of the machine, as shown, steadies it, so that it will not oscillate during the wringing operation. In order to insure this condition, I provide suitable latches 99, best shown in Fig. 4, adapted to engage suitable projections 100 upon the front of the board 97, the operator throwing these latches 99 to the position of Fig. 4, when he desires to secure the wringer board 97 to operative position and releasing the latches when he desires to throw it back out of operative position. The operative position is shown in dotted lines Fig. 1 and the non-operative position in full lines in that figure. In the latter position it rests upon the bracket 101, out of the way of the oscillating vessel.

It is desirable that when in non-operative position the wringer board be back far enough only to just clear the vessel. From this position the board with its attached wringer may be thrown back to operative position with minimum effort. Said bracket is preferably adjustable so that wringers of different makes and styles may be accommodated and each one rest when in non operative position back far enough to just clear the oscillating vessel. This adjustment is secured by slotting said bracket and providing a wing nut 101 (see Fig. 11) screwing on to a threaded stud 101 fixed to said vessel and projecting through said slotted bracket.

In order to facilitate the drawing of clothes out of the vessel in operating the wringer I journal within the machine, and adjacent to the opening in the cover, and adjacent to the base of the wringer when 1n operative position, a suitable roller 105 over which the clothing may pass from the mterior of the vessel to the wringer.

I have shown my machine as equipped to be operated by hand, but, of course, it could be operated by power.

Having thus described my invention what I claim as new and desire to secure by Letters-Patent is 1. In a washing machine, the combination with a supporting-frame and an oscillating vessel pivoted thereto, of a spring having its upper end connected to the oscillating vessel, a rod extending from the lower end of the spring, and a nut upon said rod having knife-edges bearing upon said supporting-frame.

2. In mechanism of the class described, the combination with a washing machine vessel. and its supporting frame, of a lug carried by said vessel, a bushing mounted upon said lug, a hook journaled upon said bushing, means for holding said hook and bushing upon said lug while permitting free rotation of the hook, and a spring connected to said hook and to the machine-frame.

3. In a washing machine the combination with a supporting frame and an oscillating vessel pivoted thereto of a hook plvoted to said vessel, a spring suspended from said hook, a rod extending from the lower end of said spring, and a nut upon said rod having knife edges bearing upon said supporting frame.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
