DRIVING MECHANISM FOR WASHING MACHINES.

Application filed May 23, 1918. Serial No. 236,142.

To all whom it may concern:

Be it known that I, ALPHnUs W. ALTORFER, a citizen of the United States, a resident of Peoria, in the county of Peoria and State 63 of Illinois, have invented new and useful Improvements in Driving Mechanism for Washing Machines, of which the following is a specification.

This invention has reference to washing machines, and relates particularly to washing machines of the cylinder type; that is, a machine having a washing cylinder and mechanism for revolving the cylinder alternately in opposite directions.

The invention has for its principal object, to provide bearings for the cylinder which will permit of the cylinder being removed from the machine with perfect ease, and in the provision of a driving element for the cylinder which may be moved into and out of operative relation with the cylinder, without disturbing other operative connections with the power.

The invention includes new and novel gearing connections between the motor or other source of power and the driving element for the cylinder, and also gearing connec'tions between said first mentioned gearing and the operating means for a swingable wringer mounted on said machine.

That the invention may be more fully understood, reference is had to the accompanying drawings, in whichdill Fig. 1 is a side elevation of a cylinder machine, with my invention applied thereto;

Fig. 2 is a detail sectional view, in plan, as the same would appear if taken on the line 2-2, Fig. 1;

Fig. 3 is a detail vertical sectional view as the same would appear if taken on the line 3-3, Fig. 1;

Fig. 4 is a detail in plan, partly in section, showing the reducing gearing between the motor or other source of power and the cylinder, also for operating the wringer, as the same would appear on the line 4-4:, Fig. 1;

Fig. 5 is a detail vertical section view showing operating parts connecting the wringer and the reducing gearing, and

Fig. 6 is a sectional detail of parts, as the sBa ne lwould appear if taken on the line 6+6,

Like characters of reference denote corresponding parts throughout the figures;

The clothes container washing cylinder 1 of the machine is not unlike other cylinders of this character and I need not, therefore, describe it in detail, except as to the manner of journaling it in the casing 2. On each side of the cylinder are secured trunnions 3, only one of which is shown, and this trunnion is formed with a clutch socket 4. To the opposite inside walls of the casing 2, are secured bearings 5, only one of which is shown. This bearing comprises a plate 6, secured to the casing 2, and projecting inwardly from said plate is a semi-spherical bearing member 7 having a bearing seat 8 into which is seated, as shown, the trunnion 3. The bearing 5 for the opposite trunnion 3 has a bearing seat similar to the bearing seat 8 referred to. This construction provides for a quick and easy removal of the cylinder 1 from the casing 2 and an easy replacement of the same.

The driving element for the cylinder 1 is the reciprocal shaft 9. This shaft passes through and has a bearing in the bearing 5, a casting 10 and a bracket 11. The inner end of the shaft has a clutch member 12 and for a portion of the length of said shaft, it is provided with a spline l3 fitting in a groove corresponding thereto in a pinion 14, 1ournaled in the bracket 11; sidewise movement of the pinion being prevented by the casting 10 on one side and a wall of the bracket 11 on the other side. The outer end of the shaft 9 is formed. with an annular groove 15 engaged by a yoke 16 on the end of a lever 17 fulcrumed at 18 on the bracket 11.

To clutch the shaft 9 to the cylinder 1, the outer end of lever 17 is swung away from the machine, moving the-shaft 9"endwise inwardly, causing the clutch end 12 of the shaft to enter the clutch socket 4k in the trunnion 3, and when so connected, if the pinion 14: is rotated, corresponding rotation will be imparted to the cylinder 1. To disconnect the clutch parts, the lever 17 is swung in the opposite direction, as will be understood.

The bracket 11 is formed with a hall-seat 19, into which enters a ball 20, to lock the lever 17 in position when it is swung to cause the clutch parts 4 and 12 to engage. This ball 20 is located at the lower end of a tubular boss 21 on the lever 17, said boss closed with a screw-cap 22, between which and the ball 20, in the boss, is a coil spring 23.

The casing 2 of the machine is referably supported between four standar s or legs 24, only two of which are shown, and which are preferably angle-irons. To two of these standards or legs is secured the casting 10. To the lower end of each standard or leg 24 is connected a caster-wheel 25 to permit the machine to be rolled from one place to another. 26 designates the to of the machine provided with the usual 1i not shown, and 27 is a platform at the base of the machine and between the standards or legs 24 on which is mounted the motive power and gearing for actuating the moving parts of the machine. In constant mesh with the teeth of the pinion 14 are teeth on a segment-rack 28 fulcrumed at 29 on the casting 10. At a point 30 there is pivotally connected with the segment 28 a pitmanbar 31, which, at its opposite end 32 is connected with a crank-arm 33, connected with one end of a two-part driving shaft 34. On the inner end of that part of shaft34, to which is connected the crank-arm 33, is connected a large gear wheel 35. To the outer and inner ends, respectively, of the other part of said two-part shaft 34, is connected a pulley or sheave wheel 36, and a small pinion 37. The pinion 37 meshes with and drives a gear wheel 38, on a shaft 39. The ear wheel 38 is similar to gear wheel 35. 11 said shaft 39 is a pinion 40, similar to the pinion 37, and said pinion 40 meshes with and drives the gear wheel 35. Also connected with said shaft 29 is a gear wheel 41 meshing with a gear wheel 42 on one end of a shaft 43, on the opposite end of which is a bevel gear wheel 44.

The two-part shaft 34, the shaft 39 and the gear wheels 35, 37, 38, 40, 41 and 42 are encased in the two-part casing 45 mounted on the platform 27, said casin having marginal journal bearings for said shafts and an intermediate journal bearing for the inner ends of said two-part shaft, and on either side of which are located the gear wheels 35 and 37, respectively. The shaft 43 has a bearing in a sleeve 46 connected at its outer end in the bevel gear casing 47 secured to a standard or leg 24, and housing the bevel gear wheel 44 and also a bevel ar wheel 48 connected with the lower en of an upstanding or vertically disposed wringer operating shaft 49.

Passing around the pulley or sheave wheel 36 is a driving belt 50,' and said belt, also passes over a smaller but similar wheel 51 on the shaft 52 of an electric motor 53 mounted on the platform 27.

It is understood that the motor 53 is connected with the ordinary dwelling current through a fixture, wall or ceiling socket, and

that when the current is flowing through the motor, the two-part shaft 34 is in constant operation, actuating the gears 37, 38, 40 and 35, and the crank-arm 33, whichin turn imparts movement, constantly, to the pitman-bar 31, and that the reciprocation of said bar will oscillate said segment-rack 28, first in one direction and then in an opposite direction, imparting an alternate rotary motion to said pinion 14, and said clutch shaft 9. Should the clutch part 12 of the shaft 9 be in engagement with .the clutch socket 4 of the trunnion 3, the cylinder 1 will also be alternately rotated; but should said clutch parts be disconnected, the cylinder 1 will remain idle, although the mechanism described is in operation.

When the motor 53 is once connected with the house current, the driving parts usually remain in operation, and the disconnection of operative parts must be at the machine, hence this simple but eflective clutch mechanism. The wringer is also arranged to be controlled at the machine, as I shall explain.

The wringer, designated as a whole as 50, is of the ordinary construction, including the wringer rollers 51 and 52 cared together, not shown, the shaft 53 o the roller 52 having one end journaled in a housing 54 and geared to the upper end of the shaft 49 through clutch controlled bevel gearing, not shown, under control of the operator through the lever mechanism 55. The clutch controlled gearing between the shaft 49 and the wringer shaft 53, is of a well known construction and need not be further described. It has for its object to permit the operator to reverse the operation of the wringer rollers 51 and 52, at will, or cause the same to remain idle, at will.

The shaft 49 is preferably made in two sections, see Fig. 5. To the lower end of the upper shaft section is secured a clutch member 56 adapted to have clutch connection with a clutch member 57 formed on the end of a sleeve 58 slidably carried on the upper end of the lower shaft section, in manner shown in Fig. 5 and yieldingly held in clutch connection with the clutch member 56 by means of a coil spring 59 carried on the lower shaft section and hearing between the lower end of the sleeve 58 and a pin 60 in the shaft.

The shaft 49 is encased in the housing 54 and passes down through a tubular extenthe upper end of the tubular part 62 with a transverse tubular sleeve 64. Through this sleeve extends a stem 65 threaded on its inner end, as at 66 and having a head 67 on its outer end. The threaded end of said stem is screwed into a plug 68 having a beveled face 69 adapted to bear against the lower end of the tubular extension 61. On the stem 65 between its head 67 and the end of the sleeve 64', is a ring'or washer 70, and to the head 67 is connected a handle -71 for turning the stem to tighten up the plug 68 or releasing the same, when desired. The two part shaft construction 49 is a convenient arrangement when the ma- J chine is knocked down for shipment, i. e.,

the wringer 50 withthe housing 54, tubular extension 61 and the upper'shaft part 49, clutch part 56 and gearing in the housing 5 may be detached, upon the release of the locking means, and thus facilitate the crat ing of the machine and its parts.

It is believed the functions of the various parts and the operation of the machine, as a whole, is understood from the foregoing without further detailed description.
