GEARING.

SPECIFICATION forming part of Letters Patent N 0. 793,547, dated June 2'7, 1905.

Application filed April 10, 1905. Serial No- 254,805.

To all whom it may concern:

Be it known that I, ARTHUR SoRIvENoR, a citizen of the United States of America, and a resident of Richmond, county of Henrico, State of Virginia, have invented certain new and usefull'mprovements in Gearing, of which the following is a full and clear specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2, avertical longitudinal section .of my improved casing; Fig. 3, a plan view of the lower part of the casing; and Fig. 4:, a transverse section on the line 4 4 of Fig. 2, the gearing being removed to better show the interior construction of the casing.

The object of this invention is to provide a simply-constructed casing especially adapted for that type of mangle movements covered by the patent to Johnson, No. 7 02,099, dated June 10, 1902, in which the vertical agitatorshaft has imparted to it an alternating rotary motion by means of a horizontally continuously rotated shaft, this latter shaft being provided with a knuckle or universal joint to permit its inner end to rise and fall as the pinion carried thereby passes from one side of the gear on the agitator-shaft to the other side, this gear being provided with suitable means to shift the pinion at the ends of its stroke, as is well understood in this class of mechanical movements. The need for such a casing arises from the fact that the fingers of the operator and others handling the apparatus are liable to get caught in the gearing and become injured. A further need exists owing to the fact that with the gears exposed the clothing and the hands of persons handling the machine are liable to become soiled from the oil employed to lubricate the bearings and meshing teeth or pins, as is obvious.

To the accomplishment of this object and such others as may hereinafter'appear the invention consists of the parts and combination of parts hereinafter fully described, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification,

' they form an approximate sphere.

in which the same reference characters designate like parts throughout the several views.

Referring to the drawings by letters, a designates the vertical shaft, which when the invention is applied to a washing-machine will be the agitator-shaft and which carries the segmental gear 6, which may be constructed in any suitable manner, preferably in the manner shown, and which is 'provided with the usual series of radial pins or teeth 0 and the cam-groove d. The driving-shaft e is provided with the usual flexible or universal joint f near its outer end and with the driving-pinion g at its inner end, this pinion meshing with the pins 0 in the usual manner and the projecting end of the shaft 0 being provided with a roller h, which works in the usual manner in the cam-groove cl.

The casing, which entirely incloses the gears and the joint f, consists of an upper part e' and a lower part meeting on a horizontal line 7c and bolted together by means of bolts Z, passed through corresponding side lugs on the casing-sections. are substantially hemispherical at their inner ends, so that when they are clamped together Projecting laterally from this spherical casing is a tubular extension m, half of which is formed on each section of the casing. This lateral tubular extension embraces the driving-shaft to a point beyond the knuckle-joint f, leaving only the outer end of said shaft projecting for the reception of the operating-crank. At the outer end this tubular extension is preferably made globular in shape for the reception of the knuckle-joint f. The outer ends of the sections composing the tubular extension are provided with bearings at a, which form the journal of the shaft 6. The upper and lower ends of the hub of the segmental gear bear, respectively, at 0 and 9 upon the respective upper and lower sections of the casing. The under side of the globular head is so shaped as to form a broad bearing 9, which bears against the upper side of the top of the washing-machine or other support. Securing-bolts 1' are cast or screwed into this The two casing-sections I hearing for the purpose of attaching the easing to its support. ing or support 8 is cast on the tubular extension m at a point about coincident with the knuckle-joint. This bearing or support is adapted to rest upon and be secured to the top of the washing-machine by suitable bolts t, cast or screwed into its bearing-face.

It will be observed that with a casing constructed as set forth above the driving-shaft will be free to rise and fall and at the same time all the working parts will be completely housed, thereby not only protecting the gearing from injury during shipment and at other times, but also preventing the operator soiling the clothing or soiling or injuring his hands by contact with the gearing. It will also be seen that a much larger quantity of lubricant can be employed, thereby contributing materially to ease of operation, and that the lubricant will last much longer than if the gears were exposed. The lubricant may be introduced into the casing in any suitable manner, preferably through holes a, formed in the upper section of the casing.

To guide the shaft 6 in its vertical move ments, a vertical guideway is cast on the interior of the casing at the juncture of the tubular part with the globular head, this guideway consisting of the vertical flanges 1), cast partly on the upper section and partly on the lower section, and between the shoulder or bulge w, formed at the juncture of the spherical head with the tubular extension, and the bearing 19 of the main gear an oil-pocket m is formed by means of ashoulder or flange y, cast in the bottom of the lower section of the casing, this oil-pocket being thus located directly in the path of the pinion g, so that said pinion will dip into it when it reaches the lower extremity of its movement, and thus keep the parts well lubricated. vision of a storage-reservoir within the casing for automatically lubricating the gearing is an important feature of my invention, as this type of gearing is employed in a class of machines handled by persons unaccustomed to handling machinery and who therefore usually neglect to keep the gears properly oiled,the result of which neglect is to greatly increase the friction, thereby adding to the labor of agitating the clothing in the tub and also to cause undue noise and wear. This objection is completely done away with by maintaining a supply of oil in such a position relative to the gears that the intermeshing teeth will be constantly lubricated during action, and by reason of the fact that this oil-reservoir is entirely closed against ingress of dust, as well as against evaporation, it is obvious that one supply of oil will last a comparatively long time.

It will be apparent to those skilled in the This proart that various mechanical embodiments of Another depending bear the invention are possible, and I therefore do not wish to be limited to the exact arrangementand construction shown.
