IMPROVEMENT IN CLOTHES-WRINGERS.
Specification forming part of Letters Patent No. 156,529, dated November 3, 1674; application filed July 28, 1874. E
To all whom it may concern Be it known that we, LEANDER BECKER an d STEPHEN M. SMITH, of the city and county of York and State of Pennsylvania, have invented a new and Improved Olothes-Wringer and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawing forming a part of this specification, in which- Figure 1 is an end view, partly in section, showing the frame of the wringer; Fig. 2, a
longitudinal View, with one of the rolls broken.
slots 1) in which shaft B revolves, and flanges 0, which form guards to prevent the clothes from being wound around the shafts between the end of the roll ,and the end plates. To said plates 0 are attached also the extensions (1, which support a rod or bar, 0, over which the clothes pass as they come from thewringer, and are thereby prevented from winding around the roller. D represents a portion of one end of the supporting-frame, which is pivoted with a vertical axis to an extension of the bearings 01,, and has an extension, j, which forms one side of the jaw or clamp that holds the machine when in operation. E is a second piece pivoted to frame D at 9. One end of said casting carries the set-screw F, which, with the extension f, forms the clamp that holds the machine to the tub or frame of the washer. The other end h of this casting forms a seat or an abutment against which rests the rub ber spring G. His a third portion of the frame, and is pivoted to piece D at i, fulcrumed against the rubber spring at j, and pivoted upon a vertical axis to a bearing, 70, which rests upon the top of the shaft B, and presses roll A against The novelty of our invention and the advantages which it possesses over the original invention lie in the mode of construction and operation of the parts of the frame.
Now, when the frame is fastened to the washer by means of the set-screw F the piece E acts as a lever, and so performs the double function of clamping the frame and also of regulating the pressure of the roll A upon A, for it is evident that the tighter the clamp is screwed the more compressed will be the rubber spring, and a greater amount of pressure will be transmitted to the roll A through the piece H. The piece H, moreover, is also so constructed and arranged as to render its operation, in combination with the other parts, peculiarly advantageous.
In the invention referred to upon which this is an improvement the distance from the pivot to the point against which the rubber spring presses is just equal to the distance from said pivot to the bearing of the roll, so that in that case the pressure of the rolls is. equal to the full force of the spring. In our invention, however, it will be seen that the point upon which the rubber presses against the piece H is just midway between the bearing and the pivot, thus resolving the piece H into a simple lever.
The direct pressure of the spring upon the roller is thus diminished one-half, but what is lost in power is gained in elasticity and flexibility, thus adapting the rolls to accommodate themselves more readily to the different thicknesses of clothes.
The slot b in plate 0 is made larger at the top than at the bottom, so as toadapt it to suit the different lateral inclinations of the frame when the roll A rises to accommodate the clothing. If it be found that the central 3.,The piece D, in combination with the centrally-pivoted piece E, the centrally-fulcrumed piece H, and the horizontal rubber spring Gr, substantially. as and for the purpose specified.
The above specification of our invention signed by us this 14th day of July, A. D. 1874.
