A'LVA BELGHER, OF DELHI, NEW YORK.

' Laim Patent' No. 101,087, dated March 22, 1870.

IMPROVED WASHING-MACHIR The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, ALVA BELCHER, of Delhi, in the county of Delaware andk State of New York, have invented certain Improvements in Washing-Machines,

of which the following is a specification.

Nature and Objects of the Invention.

The first part of my invention relates to the adjustment of the distance between the rubbing or vibrating head and wash-board by means of an elastic wedge, or its equivalent, in such a manner that while the distance can be adjusted to accommodate thick or thin4 Description of therD-raurings.

. Figure 1 is a side View of a washing-machine elnbodying my invention, the tub being shown in section at T.,

l Figure 2 is an end view of. the rubbing-head' and wash-board bmhined with my improvements.

Figure 3 is a top view or plan of the same.

General Description. A is the wash-board, provided with 'the usual corrugated sulface, h.

On each side ofthe wash-board A a slot, s, is made,

extending nearly the whole length ofthe frame, through which the lower ends of the guide-pins D D pass, and

in which they slide. l

B is a rubbing or vibrating head, provided with the usual fluted or corrugated rollers, c c c. It is also provided at each side with a slot or hole through which 4the guide-pinsD D pass.

D D are guide-pins., the upper ends of which pass 4through the slots in the rubbing-head, the lower ends .passing-through the slots s s in the wash-board. The

upper ends of the guide-pins are made larger than that part which passes through the slots s s in the washboard, so that they may not drop through when the Vrubbing-head is lifted off. `The upper ends of the guide-pins D D are also each provided with a slot, g, through which the rubber wedges F F pass.

E is a roller provided at each end with a flange, e. The roller E is connected with and Works between the lower ends of the guide-pins D D, the flanges e e pressing against and rolling on the under side of the washboard A when in use, as shown in lig. 2.

F Fare rubber wedges, which also act as springs. They pass through the slots q g in the upper ends of the guide-pins D D, and by their action give the required pressure during the process of Washing, which pressure can be increased or diminished at pleasure, While at the same time suicient spring is obtained to allow of the rubbing-head passing over a button or any inequality in `the fabric, without injury to the article Washed or the machine.

-The machine can be placed in any common washtub, as shown in fig. 1, the tub being shown in section at T T. The tub is placedin a simple frame, G, at the back of which rises a standard, H. A crank, a, is attached to the top of the standard H,.which crank is connected with the rubbing-head Bv by means of the pitman or connecting-rod d. By turning the handle b of the crank a the rubbing-head B is moved or vibrated up and down over the top of the washboard A, or on the clothes inserted between them.

The advantages of' this improvement are:

First, the machine can be used in connection with any ordinary wash-tub.

Second, the roller E lessons the friction, and consequently the power required to operate the machine.

Third, the rubber wedge-springs F F can be adjusted to give a light or heavy uniform pressure on either thick or thin fabrics, and do not rustand spoil the clothes like metallic springs.

What I claim as my invention and improvement in washing-machines, is- W The construction and arrangement of the elastic Wedges F F and roller E, in combination with the guide-pins D D, rubbing-head B, and wash-board A, ubstantially as and for the purposes hereinbefore set orth.

ALVA BELOHER.
