Leners Patent N0..1o2,255, (and April 2o, 1870.

IMPRovED WASHING-MACHINE.

The Schedule referred to in these Letters Patent and making part of the` same Be it known that I, J onu HABERMEHL, of the city of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement; in Washing- Machines; and I do hereby declare that the following is a clear, exact, and full description of the same, which will enable otheis skilled in the art to make and use it, reference being had to the accompanying drawings forming part of this specication.

This invention is an improvementpon the washingmachine of which Letters Patent were granted me on the llth day of January, A. D. 1870, No. 98,763, to' which reference is had. Y

The improvement consists principally upon two main points, one of which is in relation to a rim on top of the tub to catch the suds as it comes from the wriuger, or as it gushes out from the sides of the lid when the machine is in motion; and the other main point is in relation to constructing the inside of the tub in sucha manner that the currentwill circulate more freely and the clothes remain more separated and scattered than in the tub of the patent referred to.l

Figurel is a perspective view of my improved tub, showing the rim on top of the same, and the form or shape of the tub.

Figure 2 is a horizontal section of fig. l, showing how the blocks or projections which cause the motion of the uid are placed in relation to cach other, so as to produce the best result.

'Figures 3 and 4 are vertical-sections of the tub, fig. 1, showing how the blocks or projections are placed on the bottom and sides of the tub, and how the tub -of the tub at such a distance from the top as to obtain a rimor a projecting surface around the head of the tub, of suthcientdepth to catch and collect the l suds for the purposesnamed. The tub is also contracted at the top to'make` the `rim incline inward in the manner shown by' said g. 1. This rim or projection is highly ,important for a revolving tub standing inclined. Upon a little redaction it will .be observed that hot water, containing soap, and being lashed and dashed about in a violent manner, will create much suds and foam, which will gush out from the sides of the lid, which, without this rim, would fly and scatter in all directions. To do without this rim the tub would have to be so high or deep that the same would be very inconvenient to handle, and the strain or leverage would be too great upon the spindle and trame by which the tub is supported. Thus, by this arrangement, I am enabled to make a shallow tub relieving the spindle andframe of much strain, and avoid the nuisance of the water and suds scattering in all directions.

The other main point of my improvement is fully shown in figs. 2, 3, and 4. Fig. 3 showsl how letter- C of g. 2vis placed on the side of the tub, and iig. 4v shows how letter D of g. 2 is placed on the bottom of the tub. It will be observed that these projec.

tions or blocks are so placed that the current can circulate around them. Letter C does not reach the bottom of the tub by some inches, so that the current can pass underneath it, and the block, letter D, is likewise placed some inches from Vthe side of the tub, to let the current pass between letter D and the side of the tub.

By reason of placing these blocks or projections in the manner described, a large proportion of the fluid is not conveyed upward when the tub is in motion, but will run back near the side of the tub, thereby producing a counter current, so..to speak. By this arrangement the clothes will not have such a tenden-v cy to roll together into a lump, but will remain more distributed over the bottom of the tub, so as to expose a larger' surface of the clothes to the current than by my other invention referred to.

These blocks will perform best when half round, or like a semicircle, with a smooth surface, so that the clothes will glide and move freely, which will create a swift motion ofthe current.

The spindle, which is fastened to the bottom ofthe tub, the lower end of which is shown in fig-l, anda vertical section of the same is shown in figs. 3 and 4, is inserted or welded to a double cross, or a number of arms, as shown by letter E, which ought to be fastened firmly to the tub with screws or bolts, and the saidv spindle and arms ought to be made out of the best qualityl of horseshoe iron, or any strong material, and the frame upon which the tub revolves must likewise be made strong to stand the heavy strain to which the same are subject.

Fig. 3 shows how this inclined arrangement may be carried out in a tub remaining stationary while th inside revolves.

A shallow tub, dish, or round disk is placed upon the bottom of the tub standing still, and the. inner arrangement is made to revolve upon a pivot at the center, as shown in fig. 3, and is turned by means of a rod, which enters at the center at the top of the tub,

'as shown by letter B, figs. 1 and 3, running from the center of the tub to the side of the same, and passing down the side to bottom of the inside arrangement, almost in the shape of a square angle, and fastened to the bottom-with screws, or in any manner. If this rod was run straight down in a bee-line in the middle of the tub to the bot-tom, the clothes would link around it owing to the tub standing inclined.

The cheapest and the most durable way to carryI ont this inclined arrangement is to attach the blocks described to the tub, as shown in iig. 1.

Although the foregoing-described manner of placing those blocks or projectionslwill produce the best resnlt, yet I do notlimit myself to their precise form7 number', or the precise manner of placing them. Any irregular surface, or any projections placed at the bottoni or sides ofthe tub, will create a current when the tub is in motion, and even an oral tub or a square box will produce a current.

Whatl claim, as my improvement in Washing-maf
