HOLD W. EDEN, 0F CHICAGO, ILLINOIS, ASSIGNOR T0 BROKAXV-EDEN 'MANUFAC- TUBING: COMPANY, A CORPORATION 0F MISSOURI DRIVING MEANS.

To all 'whom it may concern.'

Be it known that l, HAROLD W. EDEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Driving Means; and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specication.

-As heretofore constructed devices involving the-.use of a number of shafts and gears have been more or less difficult of assembly due to the necessity of properly alining the same and truing up the various elements in order to obviate friction and wear on the parts, and to insure easy running and operation of the same. This invention relates to means permitting rapid assembly without accurate alinement of elements forming a portion of a drive for a washing machine, although it is obvious that the adaptation thereto is not necessarily limited to this particular type of construction.

It is an object of this invention to construct a reversible driving mechanism for a washing machine or the like wherein the various shafts are detachably connected together to permit operation thereof even if the same are not properly alined, thus obviating friction, wear, and binding of the parts.

It is also an object of this invention to construct a device wherein the elements are easily and quickly assembled, and wherein any art thereof may be removed, without inter erence with, or adjustment of other portions of the device.

It is also an object of this invention to construct a reversible driving gear mechanism wherein the various shafts and gears may be readily removed from the device by the removal of connecting pins which removably but positively engage the same together, thus requiring no interference with other portions of the device.

It is furthermore an object of this invention to construct a device wherein the elements are loosely 'but positively engaged together by means .of pins, thus permitting a slight play betweenthe elements, requlrlng no accurate alinerent of the same in assem- Specication of Letters Patent. v Patented Sept., 25, 191i Application led January 26, 1914.

bly, and also permitting rapid and easy assembly thereof.

It is finally an object of this invention to construct a device involving the use of elements detachably pinned to one another, permitting the removal of any one element therefrom without interference with other elements of the device.

The invention (in a preferred form) is hereinafter more fully described and delined in the accompanying drawings and specification.

In the drawings:

Figure 1 is a side elevation of a washing machine to which a particular form of this type of mechanism involving the principles of my invention is connected.

Fig. 2 is a section taken on line 2 2 of Fig. l.

Fig. 3 is an enlarged detail view of an intermediate connecting shaft illustrating the relation thereof to other elements of the device.

Fig. 4 is a section taken on line 4-4 of Fig. 1.

F Fig. 5 is a section taken on line 5-5 of s shown in the drawings:

The reference numeral 1, indicates as a whole a washing machine, which has attached thereto a wringer 2, and mounted diagonally across one end of said washing machine is a reversible driving mechanism adapted to drive both the clothes drum within the machine, and the wringer, in either direction, and either simultaneously or independently, as desired.

The driving mechanism consist of a bevel gear casing 3, in which is mounted a gear 4, adapted to be driven from any suitable source of power, such as'an `electric motor,

sel

and having rigidly secured thereto a small 'longitudinal slots adapted to receive therein a pin 10, substantially at right angles to said pin 9, said pin 10, extending through a transverse aperture in the end of an inter-` mediate shaft section 11.

A casing 12, is mounted centrally on the end of said machine, and contains therein inner end of said shaft 13, is a bevel gear 15. y'

An outer cover 16, isy provided for said casing 12, and is adapted to be secured thereon by means of bolts or screws 17. Said cover and said casing are each enlarged and extended at points on the periphery thereof to afford split bearing mem ers 18, and 19, respectively.

Journaled in said bearings 18, and 19, 1s a shaft section 20, which has feathered thereon within said casing 12, a clutch member 21, adapted to interlock with either .one of a pair of bevel pinions 22, and 23, respectively, which mesh with said bevel gear 15, and are free to rotate upon said shaft section 20. "A1 lever 24, is pivotally mounted in the upper end of said casing 12, and engages said clutch element 21, for the purpose of shifting the same into its various positions.

Secured on the outer ends of said shaft section 20, are collars 25, similar in construction to the collar 8, already described, and detachably retained upon said shaft section 20, by means of removable pins 26, Asaid collars 25, also bearing against the outer extremities of said journals 18, and 19, respectively, thus maintaining said shaft section 20, properly disposed within said casing 12. A pin 27, is secured in the end of said section 11 already referred to, and engages in the slots in vone of said collars 25, similar to the engagement of said pin 10, in said collar v8, and it is to be noted in this particular that said pins 10 and 27, are disposed at right angles to one another in said shaft section 11, so that, together with the slotted collars which receive the" same, a universal joint is afforded, which readily takes care of any irregularities in alinement of the mechanism.

A casing 28, is also secured at the upper f end of the device to contain therein the reversing mechanism for the wringer, which is -similar to .that already described. A shaft section 29, is journaled in said casing f 28, and feathered thereon is a jaw clutch element 30, adapted to engage either one of bevel pinions 31, and 32, respectively,

which are free to rotate on said shaft section 29. Both of said bevel pinions 31, and 32, mesh with a bevel gear 33, which is rigidly secured upon a shaft section 34, journaled at right angles to said shaft section 29. A' shaft 35, is directly van intermediate shaft 37, which is connected to each of said shafts by means of collars 25, and 38, respectively, the pin connections being identical with those already described.

Thus it is readily apparent that due to the pin and slot connections existing `between the various shaft sections of the mechanism, that substantially a series of universal joints is afforded, thus obviating the necessity of a delicate alinement of the parts -in the assembly thereof. Furthermore, for instance, by the withdrawal of said pins' 9, and 10, said collar element 8, may be moved over said shaft section 11, thus permitting the same to be withdrawn 'at its other end from said collar element 25, should it be desired to repair or replacethe same.

Likewise the other various elements of the device, by merely removing thepair of pins at any particular collar connection thereon, may be disassociated from one another in an easy and rapid manner without interference with other portions of the device. In order to inclose the elements to protect the same a plurality of slidable tubular elements 39, are provided, of such length as to permit a longitudinal movement thereof at one of the ends for the purpose of uncovering a collar connection to permit removal thereof.

I am aware thatvarious details of construction may be varied through a wide range without departing from the principles of this invention. I therefore do not purpose limiting ,the patent granted otherwise than necessitated by the prior art.

I claim as my invention: v

1. In a device of the class described a plurality of shaft sections, pins associated therewith, collars having apertures near one end thereof adapted to receive said pins for rigidly and detachably securing said collars on the ends of said sections, said collars having slots in the other end thereof, a plurality of shaft sections, and v'pins mounted at right angles to each other in the opposite ends thereof adapted to engage in said slots to transmit the drive between said shaft sections.

2. In a device of the class described a plurality of shaft sections, slotted and apertured cylindrical collars removably secured on said sections, aplurality of intermediate shaft sections adapted to transmit the drive and pins secured' between said shaft sections, in said intermediate sections, and in said shaft sections adapted to engage in the slots 3. In a device of the class described a plurality of shaft sections, bearings for said shaft sections, intermediate shafts adapted to connect said shaft sections, cylindrical collars having apertures and slots therein adapted to properly maintain the shaft sections in the supporting bearings therefor, and pins in said shaft sections and in said intermediate shafts adapted respectively to 10 engage in said apertures and slots in said collars to afford a flexible driving connection between said shaft sections.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

HAROLD W. EDEN.
