WASHING-MACHINE.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed March 20, 1915. Serial No. 15,788.

To all whom it may concern:

Be it known that I, WALTER J. CONLON, 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 Vashing-Machines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to washing machines and has to do particularly with the driving means thereof-that is, the provision of improved means for reversing the direction of an operating member at regular intervals automatically and without in any way affecting a driving shaft operating continuously in one direction. My purpose is to provide a simple, effective and economical structure which will secure this result.

My invention is illustrated in the accompanying drawings in which- Figure l is a front elevation of a machine embodying my invention, certain of the parts being broken away to show the driving mechanism.

Fig. 2 is a side elevation of the same with certain of the parts broken away.

Fig. 3 is a sectional view taken on the plane of the

lines

3, 3 of Fig. 1 and looking in the direction indicated by the arrows.

Fig. 4 is a view taken on the plane of the line 4, 4 of Fig. 3, looking in the direction indicated by the arrows.

Fig. 5 is a detail view in front elevation of a portion of the reversing mechanism.

Fig. 6 is a view partly in plan and partly in section of details of the reversing mechanism.

Fig. 7 is a plan view of the reversing mechanism drawn on a somewhat larger scale, and

Fig. 8 is a detail view of the reversing mechanism similar to Fig. 3, but drawn on a larger scale.

The machine comprises a combined washing and wringing machine, having a washing drum 20 and. wringer rolls 21 which are driven by the electric motor 22. The drum 20 is inclosed in a suitable casing 23 having a semi-circular bottom portion and a rectangular top portion, and provided with a hinged cover 24 which is prefcrably made of sheet metal. This cover is composed of two parts hinged at 25 and attached to the casing 23 by the hinge 26,

,to allow the cover to be moved out laterally to disengage the various projecting parts of the machine when the cover is removed. The washing drum 20 is provided with a removable gate 18 held by a catch 19, for allowing ready access to the interior of the drum.

The various parts of the machine are supported by the legs 27 which are bolted to the casing 23 and which in connection with the casing form a framework for the other parts. Pivoted rollers are provided to allow the machine to be readily moved from place to place. The washing drum 20, shown in dotted lines in Figs. 1 and 2, substantially fills the casing 23 and, when the machine is in operation, this drum 20 contains the articles which are to be washed and the casing 23 contains the washing liquid into which the drum is partially submerged. In a machine of this character, it is desirable that the washing drum be rotated a number of times in one direction and then in the opposite direction the same number of times to prevent wadding of the clothes into a compact mass inside of the drum 20.

This reversal I secure by means of the automatic mechanism now to be described.

A bracket casting 45 is bolted to the legs 27 and, in turn, the casing 23 is bolted thereto. This bracket casting 45 carries the reversing mechanism. A beveled gear 28 is provided with a sleeve portion 29, this sleeve portion being journaled in a bearing 30, formed upon the bracket 45. In the same horizontal plane with'the axis of the beveled gear 28, but at right angles thereto, a shaft 31 is'mounted in

bearings

32, 32, upon the bracket 45. Mounted loosely upon the shaft 31 next the lefthand bearing 32 is a pinion 33, and also mounted loosely upon the shaft next the right hand bearing 32 is a pinion 34, these two pinions being constantly in mesh with the gear 28. Between the two pinions 33 and 34 a shifting sleeve 35 is provided, this sleeve being provided upon its left hand end with a squared portion which fits snugly upon the squared portion 36 of the shaft 31, this construction providing for the rotation of the sleeve 35 always with the shaft 31, but permitting longitudinal movement therebetween. The sleeve 35 is provided with four collars, 37, 38, 39 and 40. Each of the outside collars is provided with a clutch pin 41 and each of these clutch pins is adapted to cooperate with a clutch pin 42 upon the

respective pinions

33 or 34. The

disposition of the pinions and. the length of the sleeves are such that when the

pins

41 and 42 on one side are in engagement the corresponding pins on the other side are out of engagement. Obviously, this means that one or the other of the pinions is in operative relation to the shaft. while the remaining pinion merely rotates loosely upon the shaft. The operative relation of these parts depends upon whether the sleeve is in its right hand or left hand position. I shall now describe the means for shifting the sleeve from one side to the other.

A. fork shaped member. 43 having an axial sleeve 44 is mounted with its axis coincident with that of the beveled gear 28. The sleeve 44 of this member fits with a-bearing disk within the sleeve 29 on the gear 28 and is internally screw threaded for a purpose to be described presently. The tangs of the member 43 embrace the shaft 31 as clearly shown in the drawings, and at their outer ends bear snugly in an opening 46 in the housing formed by the

members

47 and 48, these members being bolted to the bracket at 49 and 50 respectively, and being bolted together at 51.

The sleeve 29 provides the bearing 52 for a stud shaft 53 which, as illustrated in Fig. 3, passes through an opening 54 in the casing 23, the casing being reinforced by means of plates 55 and a bearing member 56 bolted thereto, the bearing member 56 also providing a bearing for the sleeve 29, as shown in Fig. 3. The shaft 53 is provided at its inner end with the squared drive member 57 which is pinned thereto by means of a cotter 58. This drive member fits into a socket 59 secured to the center of the drum, the opposite side of the drum being also suitably supported. \This arrangement provides for the ready attachment and detachment of the drum from the driving shaft. The shaft 53 at its other end is threaded and has threaded engagement with the interior of the sleeve 44 on the member 43. It will now be seen that when the shaft 53 is turned in one directionthe member 43 will be moved outwardly, into the position shown in dotted line in Fig. 8, and when it is moved in the opposite direction the member 43 will be drawn inwardly.

Pinned to the shaft 53 is a clutch member 60, this member being provided with the clutch engaging shoulder 61. Shoulder 61 cotiperates with a shoulder 62 which is preferably integral with the sleeve 29, as illus- -trated in Fig. 8 and Fig. 3. Engagement of these shoulders is clearly shown in Fig. 4.

Upon each side of the shaft 31 the member 43 carries a cam, the inner cam 63 being tapered outwardly and upwardly. and the outer cam 64 being tapered outwardly and downwardly. The internal faces of the

cams

63 and 64 are cut out upon a circle arranged over into its alternate position.

1,aee,see

is such that when one of the cam followers 65 rides upon the surface of the corresponding cam, as illustrated in Fig. 5 or Fig. 8, for instance, the sleeve 35 will be thrown 7 while the

collars

38 and 39 can rotate without having their cam followers engage their cam, the gear 28 will continuein a given direction dependent upon the pinion by way of which it is brought into mechanical relation to the shaft. The

cams

63 and 64 are thus placed a suitable distance apart, as clearly illustrated in Figs. 7 and 8 and the cams move back and forth, toward one cam follower and then the other in order to secure the reversing action which will now be pointed out. Assuming that the shaft 31 rotates in the direction of the arrow X of Fig. 8, it will be seen that the follower 65 on the collar 38 is riding upon the surface of the cam 64. While this following action is taking place the sleeve 35 is being moved over toward the left, Fig. 7, and when the sleeve 35 has been moved sufficiently for.the pin 41 to come into the path of the pin 42, it will pick up the pin 42 onthe pinion 33, and cause the pinion 33 to move in the direction of the arrow X, (Fig. 8). This means that the beveled gear 28 will move in the direction of the arrow Y of Fig. 1. Continuing in this movement the shoulder 62 of the clutch, which operates with the gear 28, will engage the shoulder 61 which moves directly with the shaft 53, and this means, of course, that the drum carrying the clothes will move with the shaft. The continued movement,

Now, a is.

however, does more. The threads between the shaft 53 and the sleeve 44 on the member 43 are in such a direction that when the gear and the shaft 53 operate in the direction of the arrow Y in Fig. 1, the member 43 will be moved outwardly toward'the position shown in dotted line in Fig. 8. This means that as such rotation is continued the cam 63 will gradually approach the collar 39 and eventually will lie'in such a position that the follower 65 on the collar 39 will ride upon the-surface of the cam 63. When this action occurs it is obvious that the sleeve 35 will be moved to the right (Fig. 7) and the

pins

41 and 42 for the pinion 33 will be thrown out of engagement while the

pins

41 and 42 of the pinion 34 will be thrown up the pin -12 of the pinion 3i. the pinion 3-1: will of course rotate in the direction of the arrow X (Fig. 8) and that means that the beveled gear 23 will move in the direction of the arrow of Fig. 1. This reverses the rotation of the drum and also inaugurates the inward movement of the member 43. which inward movement continues until the cam 6* has once more been engz ed by the corresponding follower 65-and this cycle of operation may be repeated indefinitely with the shaft 31 always operating in the direction of the arrow X.

It will be seen that in the reversing action the clutch has a play of half a revolution before taking eifect-that is, the

members

61 and 62 are quarter pieces and they engage on one side for rotation in one direction and on the other side for rotation in the other direction. This leaves 180 which must be passed through as lost motion during the reversing action. There is further lost motion in the take up the pins 42 by the pins 41 which may amountto nearly a whole revolution of the shaft 31. This lost motion in two places is important since it gives the drum carrying the clothes time to slow down. and it may even come to rest and thus jarring or straining of the mechanism which would occur in overcoming inertia of the moving drum if its movement were immediately reversed. is obviated. This inertia is augmented by the fact that clothes will sometimes cling to the sides of the drum and will tend to rotate the drum ahead of the driving means so that I make it a particular point to give the drum time to come to rest. or nearly that. in my reversing action. This not only saves the machinery but it secures quiet action and is consistent with the purpose of the .shock absorber, which I have indicated at- 66, but which is not concerned with my present invention. The details of this shock absorber are described in my co-pending application, Serial Number 833,045 filed April 20th, 1914.

The shaft 31 is driven through the beveled gears 67 and 68 from the main shaft 69 which is connected to the motor shaft by means of the gear wheel '76 and the worm 71 mounted on the extension of the motor shaft. The beveled pinion 68 is loosely mounted on the shaft 69 and is adapted to be clutched to said shaft only when it is desired to actuate the drum of the washing machine.- An extension 72 of the shaft 69 is connected to gears (not shown) to the ringer rolls .21. The clutch controlling the washing mechanism in and out of gear com-.

prises a projection '73 mounted on the pinion 68 and a projection 74.- mounted on the sliding sleeve 75. This sleeve is keyed to the shaft and whenshifted into the lower position where the

projections

73 and 74 engageeach other, power is transmitted to the washing mechanism. The sleeve 7 5 is provided with a groove into which a U- shaped shifting fork 76 is fitted. A rod 77 is connected with a controlled lever 78 within a control box 79 with the details of which I need not here be concerned. It is suflicient to say that the movement of the lever 78 throws the clutch in and out.

A beveled gear 79 is mounted upon the extremity of the ringer shaft 80. .It is sufficient here to say that this beveled gear is operated through the medium of they shaft 72 by means of connection mechanism within the control box 79 and that the lever 80' controls the direction as well as the completion of this connection.
