IMPROVEMENT IN WASHING-MACHINES.
Specification forming part of Letters Patent No. 205.784, dated July 9, 1878; application filed April 23, 1878.
To all whom it may concern:
Be it known that we, JOHN H. CARRIER, BARTON R. BAKER, and WILLIAM MOGARTY, of London, in the county of Laurel and State of Kentucky, have invented a new and Improved Washing-Machine, of which the followin g is a specification: V
In the accompanying drawing, Figure 1 represents a sectional side elevation of our improved washing-machine; and Fig. 2, a top view of the same.
Similar letters of referenceindicate correspondin g parts.
This invention has reference to an improved washing-machine of that class in which a reciprocating pounder and an intermittingly-revolving tub is used.
Referring to the drawing, A represents the supporting-frame of our improved washingmachine B, the wash-tub; and O, the pounder of the same. The wash-tub turns by a central bottom shaft, B, in bearings of the baset'ralne, and is revolved by suitable belt-andpulley connection with the operating crankshaft, the pulley of the tub being made either in one piece with the bottom of the same or attached otherwise to theshaft of the tub. To the crank-shaft D is keyed a cog-wheel, a, that gears with the pinion b of a second crankshaft, D To the outer end of the second crankshaft D is pivoted an intermediate crank-rod, d, which is perforated at the upper end and connected by a pivot-pin in adj ustable manner with the fulcrumed operating-lever D of the reciprocating pounder O. The front end of the operating-lever D is pivoted to the stem of the pounder, the same being, li kc the crank-rod, adjustable to a greater or less height, so as to regulate the stroke of the pounder.
The stem of the pounder is guided in a forked arm of one of the upright standards of the machine, so that a regular and reliable motion of the pounderis obtained. The pounder strikes between the center and circumference of the tub, and is provided with an annular concave cavity, so as to Work in effective manner successively on all the clothes in the wash-tub, as the same revolves by the beltand-pulley connection with the main crankshaft.
The belt of the wash-tub is kept at a proper tension by means of an idler, 0, so as to produce in reliable manner the simultaneous revolution of the tub with the reciprocating motion of the pounder.
We are aware that it is not newin washingmachines to use a revolving tub and reciprocatin g pounder, both Operated simultaneously, and belt-and-pulley mechanism of a similar character to ours.
Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- A Washing-machine employing a pounder and rotary tub, and having its pounder-stem operated by means of the lever D crank-rod d, crank-shaft D pinion b, and crank-shaft D, having cog-wheel a, all arranged substantially as shown and described.
