i ACTUATING MECHANISM.

Specification of Letters Patent.

Patented Dec. 20, 1910.

Application filed.` February 24, 1910. Serial No. 545,574.

To all 'whom t may concern:

Be it known that I, JAMES B. JARMIN, a citizen of the United States, residing at Spokane, `in the county of Spokane and State of lVashingt-on, have invented a new and useful Actuating Mechanism, of which the following is a specification.

This invention relates to mechanism for actuatingv washing machines and its principal object is to provide mechanism whereby the rotary agitator or pounder of a washing machine may be given an intermittent movement in opposite directions successively, each movement thereof beginning abruptly or with a sudden jerk so as to force the fabric very rapidly through the water within the tub and thus drive the water through the fibers and therefore facilitate the cleansing of the fabrics. Y

Another obj ect is to provide a machine of this character the operating mechanism of which is compact in construction and easy to operate. Y

With these and other objects in view the invention consists of certain novel details of construction yand combinations of parts hereinafter more fully described and pointed out in the claims. c

In the accompanying drawings, the preferred form of the invention has been shown.

'In said drawings -Figure 1 is a view partly in section and partly in elevation of a. washing machine constructed in accordance with the present invention. Fig. 2-is a bottom plan view of the machine the actuating lever and its connections being removed. Fig. 3 is a plan view of the connection between the actuating pitman and the shank or spindle of the agitator and of adjacent parts. Fig. 4 is a sect-ion on line A-B Fig. 3.

VReferring to the figures by characters of reference 1 designates a tub preferably cylindrical and having a flange 2 at its lower end to which is riveted or otherwise secured the bottom 8. A bracket 4 is secured to the l flange at the bottom of the tub and extends under saidbottom to a point under the center of the tub, the said bracket being pro- I vided at this point with oppositely extending arms 5 which -are also secured to the flange. A journal 6 is formed at this end of the bracket and has a shaft 7 mounted for rotation therein, the said shaft being provided at its lower end with a gear 8 while a fly wheel 9 1s secured to the upper end of the shaft and bears downwardly upon the journal 6. This Hy wheel lies close to the bottom of the tub.

A hanger 10 is formed upon the bracket 4 at a point between the ends thereof and a shaft 11 is ournaled within this hanger and has a gear 12 secured to the lower end thereof and meshing with the gear 8. It is of course to be understood that these gears are held above and out of contact with the floor or other supporting surface by means of legs i 13 which are attached to the tub and extend downwardly therefrom. I

A wrist pin 14 issecured to and mounted for rotation in the gear 12 and has a pitman 15 pivotally connected to it, the said pit-t man being also connected, by means of a universal joint 16 to the lower arm of abell crank lever 17 which is fulcrumed in a bracket 18 secured to the flange 2 and extending outwardly therefrom. The upper arm of this bell crank lever is connected by a strip 19 tothe lower arm of another bell crank lever 20. This last mentioned lever is fulcrumed upon a bracket 21 secured to the wall of the tub 1. The other arm of the lever 20 is elongated to constitute an operat ing handle 22 which extends a considerable distance above the tub. If desired this handle may be removably mounted within a f around a sleeve 42.` This sleeve has an angular passage 43 extending longitudinally therethrough and is also formed with an annular shoulder 44 which bears downwardly on the ring 31.

A tubular member 45 is mounted tor rotation on the sleeve 42 and is formed at one end with an arm 46. This arm has a slot 4T therein at a point between the ends thereof, the said slot being preferably concentric with the sleeve 42 and having a stud 48 loosely mounted within it. Said stud extends upwardly from an arm 49 which is integral with and extends radially from the sleeve 42. The upper end of the sleeve 42 bears within the end of a bracket 50 which may be secured in any suitable manner to the cover A stud 51 projects from the arm 46 and is engaged by a pit-man 52 having a hooked extension 53 at one end and which detachably engages a connecting pin 54, which is supported by ears 55 extending from the socket portion 23 of the lever 20.

An angular spindle 56 is slidably mounted within the annular passage 43 in sleeve 42 and has a head 57 at its lower end from which extend downwardly diverging agitating fingers 5S. A ring 59 may be connected to the upper end of the spindle so as to limit the downward movement thereof within the sleeve 42 and to facilitate the elevation of the spindle and the head which is connected to it.

In using the machine herein described the pitman 52 is disengaged from the pin 54 and the cover 24 can then be raised and the water and fabric placed vwithin the tulo.

-The parts are then replaced and when the handle 22 is oscillated motion will be transmitted through the lever 20 and strip 19 to lever 17 and this will in turn transmit motion through the pitman 15 to the gear 12. Gear 8 and its shaft 7 will thus be rotated at a high speed and the fly wheel 9 will move therewith. At. the same time motion will be transmitted through the pit-man 52 to the arm 4G and said arm will be partly rotated back and forth. During the first portion of each movement of the arm 46 it will move independently of the arm 49 but, at a predetermined point during such movement of the arm 46, one of the end walls of the slot 47 will strike the lug 48 and thus start a corresponding movement of the arm 49 and sleeve 42. Spindle 56 and the agitator at the lower end thereof will thus be also started and, during the reverse movement of the arm 46 the agitator, its spindle 56 and the arm 49 will remain stationary until the other end wall of slot 47 strikes lug 4S, whereupon said parts will be again started with a sudden jerk in the opposite direction. Importance is attached to this intermittent jerking movement of the agitator because it starts the clothes through the water at a speed which is maintained throughout the movement of said agitator and causes the water to rush between the fibers ot the fabrics and thoroughly cleanse them to an extent not possible where the starting and stopping of the fabrics and their agitato-r is gradual.

By providing a iiy wheel, the high speed of the operating mechanism can be maintained irrespective of the sudden starting and stopping of the agitator. It is'to be understood that said agitator can be raised or lowered whenever desired after the cover 24 has been placed upon the tub and without disconnecting it from its operating means.

Various changes can of course be made in the construction and arrangement of the parts without departing `from the spirit or sacrificing any of the advantages of the invention as defined in the appended claims.
