Specification forming part of Letters Pat-ent No. 122,220, dated December 26, 1871; reissue No. 5,218, dated January 7, 1873. Y

To all whom 'it may concern:

Be. it known that I, JACOB BRINKERHOFF, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Clothes Wringers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which Figure 1 represents a perspective view of the wrin ger. Fig. 2 represents a vertical longitudinal section through the same. Fig. 3 represents an end elevation, viz., ot' that end of the wrin ger opposite to the crank gear. Fig. 4 represents a section through the rollersprings, showing the device for holding them together.

Similar letters ot' reference, where they occur iu the several separate iigures, denote like parts in the drawing.

My invention consists, tirst, in the arrangement of the driving-gear by which the rolls are turned while they yield to allow the material to pass through between them; also, in operating the upper roll from the crank end, in order to obtain a greater purchase, and in the combinationv and arrangement of parts, as hereinafter more fully described and pointed out by the claims. 1

To enable others skilled in the art to make and use my invention, Iwill proceed to describe the same with reference to the drawing.

A A represent the side pieces of the wring er, which are slotted down to receive the journals ofthe rolls and their supports, as also to receive a box or frame, B, to which the jour nals c b c of the gears d e j' are so connected or attached that they cannot get out ot' gear, however much the upper roll may rise from the under one. The rolls, of which C is the upper and D the under one, are covered with rubber, in the usual well-known way. The journal b of the upper roll passes through the box B, and has fastened upon it, outside ot' said box, the gear-wheel e. The journalt' of the under roll is not connected with the box B, but is supported and turns upon a bearing, g, which is on, or a part of, the frame A. The journal a upon which the pinion d is hung and turns is cast or Wrought onto the box B; and

the journal c on which the gear f is permanently fixed is a prolongation of a countershaft, E, which extends clear across the wrin ger, and has, upon its opposite end from the gear f, a gear, h, which meshes with a gear, j, fast upon the journal 7c of the under roll D, and gives said under rollits revolving motion. The crank F, for cheapness and economy, is cast upon and as a part'of the pinion d, and both the pinion and crank turn on the journal a cast upon or otherwise fastened to the box B.

By uniting the journals ab c to the box B their wheels d c f cannot, of course, ever get out of gear; but as the under roll D has no connection with this box B, said box and the upper roll can leave the under roll, and form suiiicient space for any practical thickness of clothes to pass through.

By driving the upper roll U fromA the crank end I am enabled to use a pinion, d, ot reduced size, thus gaining purchase and requiring less power to operate the machine.

The under roll is turned through .the gear f, countershaft E, and gears h j, so that its motion is not stopped when the train of gears d ef rise up without raising said under roll.

The advantage of this mode of gearing is, first, it does not tear or twist ott' the rubber covering of the rolls; second, the gears cannot separate; and, third, the great amount of space between the rolls for the passage of the clothes.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, ise 1. The combination of two rolls and suitable connecting mechanism with a countershaft having a tixed journal at one side of the frame and asliding journal at the other.

2. The combination of the rolls G and D, arranged, with gearing and sliding boxes and journals, to allow one or both ends of the rolls to be separated Without changing the relative position ofthe gearing.

3. The combination of the train of gears d c f with the box B, so that they shall always move together, and consequently be always in gear with each other While they move up and down with the upper or yielding one of the pair of rolls, substantially as described.

4. In combination with the train of gears neoting mechanism to obtain the required purand the under roil detached from the box B, chase, substantially as and for the purpose set the countershaft E and gears h j for driving forth.

said under roll, substantially as described. JACOB BRINKERHOFF.

5. The upper roll C, driven from the crank end by a pinionof smaller size than the pinion Witnessesz upon the shaft of roll C, and the lower roll D, JOHN A. ELLIS7 driven from the opposite end by suitable con WM. K. ELLIS.
