SPECIFICATION forming part of Letters Patent No. 721,502, dated February 24, 1903. Application iilcd August 2'11,- 1902. Serial No. 121,246. (No model.)

To aZZ whom it may concern/r l Beit known that I, JOHN R. `OARTER,.a resident of Augusta, in the county of Bracken and State of Kentucky, have invented certain ,new and useful Improvements in Pitman Connections; and I do hereby declare the following to be a full, clear, and exact description of the invention,'such as will enable others skilled inthe art to which lto make and use the same.

My invention relates to an improvement in pitman connections, and more particularly to it appertains -improvements of this character for use on washing-machines, the object of the invention being to provide a connection which will hold the parts in working position without danger of disconnection and, further, to `provide an improved bracket formingone member of the connection which can be struck from sheet or malleable metal or cast, as preferred.

With this object in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

`In the accompanying drawings, Figure lis a view in section of a Washing-machine with my improvementsthereon, and Figs. 2,3, and

4. are views of details of construction.

1 represents the body of a Washing-machine;

and 2 the cover thereon. j

3 represents the lower rubber, mounted to reciprocate in the body, and 4. the upper rub' The upl' per rubber is provided with a standard 5,'projecting through a slot i-n thecover, and is' ber, pivotally mounted. in the cover.

connected by a pitman 6 with the crank-shaft 7, supported on the cover, and a pitmanS, which is 'removably connected; to one end of pitman 6 and to the crank-shaft, projects down through the slot inthe cover and is conf nected to one endjof the lower rubber by my improvements, as will n ow be explained.

To the endof lower rubber 3 my improved bracket 10 is secured and comprises parallel arms 11, lhaving openings or notches therein to be secured to the rubber by bolts or screws, the upper ends of the arms having inwardly projecting shoulders 14 to set over the upper edge of the rubber end, and said shoulders are connected by a cylindricalv bearing. 12,

or sheet metal, a blank, such as shown in Fig.

4, is provided and bent between its ends, forming the cylindrical bearing 12,y then extending approximately parallel a short distance tov form the contracted neck 13, then bent at .right angles, forming shoulders 14', and again bent at right angles, forming the parallel arms 11to be secured against the opposite sides of the end of the lower' rubber, as above'ex'plained. y

l The lower end of pitman 8 is offset, as shownyto center the pitman withthe bracket and is provided at its lower end with a cylindrical trunnion 15, projecting at right angles thereto and adapted to lit bearing 12, and'on the outer end of trunnion 15 and projecting at rightangles thereto isa locking-pin 16, which is adapted' to move through contracted neck 13, and when the trunnio'n'moves in the bearing to dispose the locking-pin out of alinementV with neck 13 the pin will elfectually cidental disconnection. j A .The operation. ofgny improvements is as follows: When the parts are assembled, the

.upper end of pitman 8 is connected with the Ycrank-shaftand the bracket end of lowerY rubber 3 vforced upward ou-t of its working position, whenl the bracket will be in position topermit the trunnion to enter the bearing ,lock the parts together without danger of acv f `12 with the pin 16 enteringthe contracted neck 13, and when placed therein and moved through the bracket'the lower rubber is permitted to' assume a working position, when the Vpin on thetrunnion will be out of alinement with the contracted neck andlock the parts together until it is Adesired to diseon nect'the pitman, which can be accomplished.l

by forcing the lower rubber up out of its working position -to aline the locking-pin 16 and contracted neck 13.

A great many changes might be made in the vgeneral form and arrangement of the several parts described Without departing from my invention, and hence I do not limit mysell. to the precise construction set forth, but` consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is Y l. The combination with a bracket constructed with two depending arms, an eye and a contracted opening between the arms and eye, of a pitman provided with a laterally-projecting trunnion adapted to fit in the eye or bearing of the bracket, said trunnion being provided on its outer end with a locking-pin arranged to project at right angles thereto, said locking-pin being adapted to be inserted through the contracted opening between the arms and eye, and when rotated ont of alinement therewith, to lock the trunnion against displacement, substantially as set forth. y

2. The combination with a bracket constructed with two depending arms, an eye, a contracted opening between the arms and eye, and shoulders formed on opposite sides of said opening, of a pitman provided with a laterally-projecting trunnion having a locking-pin adapted to be inserted through the contracted opening between the arms and eye, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

.JOHN R. CARTER.
