HAMILTON SMITH,
WASHING- OF NEW YORK, N. Y.
MACHINE.
SPECIFICATION forming part of Letters Patent No. 402,865, dated May 7, 1889.
Application filed September 29, 1887. Renewed February 18, 1889. Serial No. 300,390l (No model.)
To all whom, it may'concern.-
Be it known that l, HAMILTON E. SMITH, a citizen of the United States, residing at New York, in the county and YState of New York, have invented new and useful Improvements in IVashing-Machines, of which the following is a specification.
This invention consists in the construction of washing-machines, as hereinafter described and claimed.
Figure l isa longitudinal central section of the device in the plane Fig. 2. Fig. 2 is a section in the plane y y, Fig. l. Fig. 3 is alongitudinal central section of a cylinder. Fig. 4 is a section in the plane .e e, Fig. l. Fig. 5 is a section in the plane e e, Fig. et.
Similar letters indicate corresponding parts.
In the drawings, the letter A indicates a case, and B is a cylinder. From the heads of the cylinder project gudgeons C. On the interior of the heads of the case A are formed bearings D for the gudgeons C. In the example shown in the drawings the bearingsD are represented as having anti-friction rollers E for the support of the gudgeons C, whereby said gudgeons and the cylinder B are enabled to rotate easily. By locating the bearings D within the case A the gudgeons C can be so formed as not to project through the case A. As the perforation in the case necessary for the passage of the gudgeons might cause leakage of the contents of the case, such perforation of the case is to be avoided.
A spurgear, F, is made to embrace the cylinder. Said spur-gear is shown as being made double, or as consisting of two spurgears. A shaft, H, is journaled on the case A, and gears with the spurgear F by means of the gear-wheels G. Pulleys I I are shown secured to the shaft in the usual manner, one pulley being fast and the other loose. A cap or cover, J, is shown as protecting the gearwheels G. The shaft Il is made to rotate or oscillate the cylinder.
The cylinder B is provided with a partition, K, which divides the cylinder into two compartments, and which strengthens the cylinder-walls at the place where the spungear F is applied to the cylinder. Doors L allou7 of the introduction into. the cylindencomparta ments of the articles to be washed.
The case A is made sectional or in the shape of a half-case, so that the upper portion of the case is open. Said sectional case is closed by a cover, M. Near the edge O of the cover M is applied a ledge, N, so as to form a recess on the cover, said recess being formed to receive and embrace the edge of the sectional case, so as to secure a tight closing of the case.
In the operation of the device the cylinder B is iirst rotated in one direction and then in the opposite direction. Such reversing of the motions of the cylinder B would cause a jarring or striking of the teeth of the spurgear F and wheel G, if such wheel and spurgear were single, in consequence of the backlash of said teeth. To prevent such backlash, I make the spur-gear F and the cog-wheel G each of two toothed rims, and place the teeth of one rim or of one set of rims slightly in advance of the teeth of the other rim or of the other set of rims a sufficient distance lto destroy such backlash. Such backlash can be prevented, for example, by either placing the teeth of one rim of the wheel G slightly in advance of the teeth of the other rim of said wheel, or by placing the teeth of one rim of the spungear F slightly in advance of the teeth of the other rim of said spur-gear, or by placing both the teeth of one rim of the wheel G and of one rim of the spur-gear F slightly in advance of the teeth of the other rim of the wheel G and of the other rim of the spurgear F. In practice the most convenient plan Will be to advance only the teeth of one 4rim of the wheel G slightly beyond the teeth of the other rim of said wheel a sufficient distance to prevent backlash. A
In the example shown in the drawings the spur-gear F is applied at or near the center of the cylinder B, so that the po wer which actuates the cylinder is centrally applied instead of being applied at or near an end of the cylinder. By applying the power centrally to the cylinderB the power is evenly distributed to both ends of the cylinder and strain of the cylinder is prevented.
What I claim as new, and desire to secure by Letters Patent, isA
A washingnnachine composed of the case A, having a cover, M, and cap J, the bearings D, located within the said case at each end IOO thereof and having anti-friction rollers E E, In testimony whereof I have hereunto Set the cylinder B, having gudgeons C C, engagmy hand and seal in the presence of two subng said anti-friction rollers, the spur-gear F, serbing Witnesses.
