CRANK-HANDLE.

SPECIFICATION forming part of Letters Patent No. 508,218, dated November 7,1893.

Application filed March 27. 1893. Serial No. 467,679. (No model.)

To all whom t may concern.-

Be it known that I` WONG I. GONG, a subject of the Emperor of China, residing in the clty and county of New York, in the State of New York, have invented a certain new and useful Improvement in Crank-Handles, of which the following is a specification. My improvement relates to the crank. It 1s common to provideacrank-handle of wood, which is capable of revolving on a cylindrical bar of sufficiently stout wire stifdy set in the crank, and constituting the crank-pin. Under the conditions obtaining in the use of clothes-wringers, theI metal of this bar oxidizes, and the rust washed therefrom is liable to do much mischief by staining the clothes. Any ordinary plating of metal is liable to be abraded and removed by wear.

I have devised aconstruction which allows the use of iron or steel for the crank-pin with the great strength which they possess, and allows the water to move freely through the joint between the end of the handle and the crankwithout allowing the circulation of any water from the wearing part of the crankpin. Only slight changes are required in the crank and handle.

The accompanying drawings form a part of this specification and represent'what I consider the best means of carrying out the in- Vention.

Figure l is a front view of an ordinary wringer to which the invention is applied. Fig. 2 is a perspective view of the crank without the pin. Fig. 3 is a section through the end of the crank and the attached handle, with an edge view of the remaining portion of the crank. Figli is an outline on a larger scale, showing more clearly the peculiarities of the construction at the junction of the handle and thecrank-pin with the crank.

Similar letters of reference indicate corresponding parts inall the figures Wherevthey appear.

A is the body of the crank, which may be of malleable cast iron, and A', A2, is an eX- tension cast integral therewith at the point where the crank-pin is attached.

A2 is a button, having av smooth exterior face, and A' a neck considerably smaller, which connects it to the body of the crank A. The rigidly attached crank-pin is marked B.

A head B' on the outer end retains the hanvdle O. The portion B2 which is inserted through the crank A, neck A' and but-ton A2, is a little smaller than the yremainder of the length so that it formsashoulder which rests rmly against the outer face of the button A2, so that on riveting a head B2 on the end of the contracted part it is tirmly,and permanently held.

In preparing the handle, I bore a cylindrical hole c with a smooth face adapted to receive the neck A' and button A2, and make a tight joint against the smooth outer face of the latter. The joint between the end of the handle and the body of the crank A may be open. may flow over and about the junction of the handle C with the crank A, and 'may circulate freely through the joint between the end of the handle O and the cast iron A, and through the cavity c, but it will only comein contact with the cast iron neck A', and the button A2. It never gets beyond the tight joint made between the outer face of the button A2 and the adjacent wood of the handle. Little rust is formed on the effective part B of the crank-pin, and it can never circulate through the joint and flow inward on the crank or spatter in any manner from the handle so as to get upon and injure the clothes.

Modilications may be made without departing from the principle or sacrificing the advantages of the invention. The neck A' may be contracted or increased in length. The button A2 may be slightly enlarged and nicely finished 0n its periphery so as to make a tight iit piston-wise as well as axially in the smoothly bored and smooth-ended cavity c; but I do not esteem these points essential.

All the metal parts may be galvanized.

I claim as my invention- 1. In a clothes-wringer, the crank Aof cast metal, provided with a button A2 cast integral therewith, having a smooth outer face, in combination with the handle'V C having a smooth bottomed recess c receiving such button, and with the crank-pin B having a smaller portion B2 extended through the button, all arranged for joint operation substantially as herein specified.
