IMPROVEMENT IN CLOTHES-WRINGERS.

Specification forming part of Letters Patent No. 126,774, dated May 14, 1872.

Specilication describing a new and useful Improvement A in Glothes-VVrin gers, invented by CHARLES W. BAssETT, of Newton, in the county'of Middlesex and State of Massachuset-ts.

My invention relates to that class of wrin gers that have their rolls connected together by gear or cog-wheels, which as heretofore con- `structed have been limited, as to the distance the rolls could be separated without being thrown out of gear, by the length of the tooth of the gear-wheels connecting the rolls; and

the object of my invention is the production of a geared wringer, the rolls of which may be separated a distance nearly twice the length of the tooth of the gear without being thrown out of gear; in fact, to make it impossible to throw it out of gear; and it consists in the use of two gears of equal diameter, one upon the crank-end of either roll-shaft, the one upon the lower roll-shaft having a width of face equal to twice the width of the one on the upper roll-shaft into which it meshes, as well as into another gear of somewhat larger diameter mounted upon a fixed stud in a stand forming a part of the frame, said last-mentioned gear meshing into another gear of equal size and width of face with the one on the lower rollshaft, and placed directly above lthe others and at such a distance that, when a large article is being passed through the rolls and the rolls are forced asunder thereby, the teeth on the upper, side of the gear on the upper roll shall engage with the upper gear of the train before it is disengaged from the gear on the lower roll-shaft, and be driven thereby in the same direction, as will be described.

Figure 1 of the drawing is a front elevation of a wriu ger with my improvement attached, a portion of one end being shown in section;

v and Fig.2 is a vertical section through the rollshafts on line .fr on Fig. l and showing the gearing in elevation.

A A are the standards, and BB are the tiegirts, altogether constituting the frame of the machine. roll and D and D are the boxes in which they have their bea-rin gs. E is a pressure-bar, resting at either end on the rubber spring F, and controlled by the set-screws Gr. His a crank, secured to the lower roll-shaft C2, all of the p above bein g constructed in a well-known man ner and is no part of my present invention.

C is the lower, and G1 the upper- Upon the end of the upper roll-shaft C3 is mounted the gear-wheel a, which meshes into and is driven by the gear-wheel b of equal diameter, but double the width which is secured to the lower roll-shaft O2. I is a stand, secured to the standard A at its lower end, and provided with a stud, c, projectinginward therefrom, upon which is mounted the gear-wheel d, of the same thickness as the geara, but ot. a diameter somewhat greater, and so located as to mesh into and be driven by the gear b on the lowerroll-shaft C2.V The stand I extends upward still further, and is connected to the frame at its upper end by the stud e and plate f. Upon the stud e is mounted, so as to revolve freely thereon, the gear-wheel g, of the same diameter and width of face as the gear b, and meshing into and being driven by the gear d revolving freely on the stud cf The gears cl and g are simply idle-wheels-fi. e., though they revolvethey do no work so long as light or medium'articles are passing through the rollbut when a large article like a heavy blanket or bedspread is passed through the rolls, forcing them apart to so great a distance as to disengage the gea-r a from the gear b, the gear a will engage with the gear g, and power will be transmitted to the upper roll through the gears d, g, and a, the gearb being the driver at all times.

Although this arrangement of gearing was designed especially for operating the rolls of wringing-machines, it is obvious that it is equally applicable to other pressure-rolls, the distance between which is variable; therefore I do not wish to confine myself to its application to wringers.

`Havin g thus described' my improvement, what I claim as new, and desire to secure by Letters Patent of the United States, is as follows:

The within-described arrangement of gearing, consisting of the gears a, b, d, and g, constructed and applied as herein set forth, for

the purpose of operating a pair of variable pressurerolls, substantially as described.

Executed at Boston, this 29th day of J anuary, 1872. CHARLES W. BASSETT.
