IMPROVEMENT IN WASHING-MACHINES.
Specification forming part of Letters Patent No. 222,472, dated December 9, 1879 application filed May 21, 1879.
which the following is a specification, reference being had to the accompanying drawings.
The invention relates to an improvement in washing-machines; and it consists in the devices hereinafter set forth and claimed.- The object of the invention will fully appear hereinafter.
Figure 1 is a top view of a device embody- Fig. 2 is Fig. 3 is a central ver- In the accompanying drawings, A A represent the two end pieces of the machine, the
length of which will vary according to the size of the tub-in conection with which it is to be employed. The ends of the sides are beveled so as to snugly fit the tub, and are supplied with buttons to secure it in place. The ends A A are connected by the cross-pieces B, the outer edges of which are cut away and beveled, as shown, to permit the articles to be washed to pass readily over them. 4
Between the cross'pieces B are mounted in the sides of the machine the three small rollers a, the axle of the central one of which being slightly below those of the side rollers.
The ends A A centrally above the middle roller a, are provided with corresponding slots,
in which is placed the axle cl carrying the fluted drum or cylinder D. This axle has afree vertical movement in the slots, and the drum D is directly above and in close proximity to the rollers a.
Above the drum D is horizontally arranged the pressure-bar b, having on each end a slotted hanger, c, which passes downward through a the upper ends of the springs 2 the other ends of which pass downward and are secured to the sides of the machine. The purpose of the crossbar b and springs t is to exert a downward tension upon theaxle d, and consequently force the drum D down in contact with the rollers a. If it is desired to cause the drum D to press with greater force upon the rollers a, it is simply necessary to bear upon the pressure or cross bar b with the hand or by means of the lever or bar 111, one end of which is detachably secured in a loop upon the side A, while the other end passes diagonally across the machine and bar b in close proximity to the operator. One end of the axle d is fashioned into a crank by which the machine may be set in motion.
The machine being in position over a tub containing water, the articles to be cleansed are saturated therein and then passed, piece by piece, rapidly backward and forward between the fluted cylinder D and small rollers a. When the bar m is not required it can be detached and laid aside. It is obvious, however, that by the use of it the pressure upon the clothing can be regulated according to the will of the operator.
What I claim as my invention, and desire to secure by Letters Patent, is
The pressure-bar b, placed longitudinally above the cylinder D, and provided upon its ends with the slotted hangerse, having loops f and springs z depending over the sides of the machine, and the latter secured to their lower portion, in combination with the said cylinder D, the rollers a, and the lever 122, sub- I stantially as specified.
In testimony that I claim the foregoing improvement in washing-machines, as above described, l have hereunto set my hand this 30th day of April, 1879.
