SPECIFICATION forming part of Letters Patent No. 356,913, dated February 1, 18E7.

Application filed him-c112, 1856. Serial No. 158,766. (No model.)

To all whom it may concern:

Be it known that I, LEWIS BENNETT, a citi- Zen of the United States of America, residing at Litchfield, in the county of Herlrimer and State of New York, have invented certain new and useful Improvements in MopWringers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to improvements in mop-wringers; and the invention consists of the combinations of parts, including their construction, substantially as herei uafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a mop-wringer embodying my invention, a partbeing broken away to expose the front roller tension-spring. Fig. 2 is a sectional front elevation thereof, taken on the line m, Fig. 1. Fig. 3-is a plan view of the same. 4 is a detailed perspective view of the foot of a hind or rear leg of astandard,with the upper portion of the leg broken away, also of the attaching-bolt; and Fig. 5 is aview in perspective of the treadle-levers and the adj unctive parts with the roller operated thereby, the whole being removed from the frame.

In the embodiment-of my invention I employ standards A, in general of the usual construction, in and between the upper ends of which are journaled the wringing-rolls B. B, roll B having, as is common, its trunnions or axes supported and arranged to slide in curved slots a. in crosspieees 0, cast or formed with and uniting the divergent ends of the upper arms of each standard. The other roll, B, has its trunnions or axes bearing in sockets, one half of each of which is formed in one end of a slot, a, in the forward end of each cross-piece 0, while the other half of each socket is formed in a block, b, fitted in said slot a. Said block is held to its place against the roll trunnion or axis by a spring, (2.", also inserted into said slot and acted upon by a holding and adj usting screw, e, fitted to work in a tubular extension,f, formed upon the forward end of each cross-piece G of a standard, A. Primarily these springs have for their object to permit the yielding of the front or forward roll at one or both ends, should the same be unevenly acted upon by the uneven thickening up of wringing action of the rolls. The screws serve to adjust the tension of the springs to compensate for wear in the holding-blocks b.

D D are the foot-levers, consisting each of a long and a short arm, d d, which, unlike the common form, are devoid of the upward extensions, said levers being pivoted one to each upper rear arm of a standard, A, at the point oi'juncture of the long and short arms of the levers or treadles. The outer forward ends of the long arm D of the levers are, as customary, connected by a cross-bar, d", forming a treadle designed to receive the foot of the person performing the wringing operation. Upon the same pivots connecting the levers D to their supports or standards are also secured or supported bars D, the upper ends of which are connected to the projecting ends of the trunnions of the sliding roll 13. The bars D are detachably connected to the pivots or fulcrums of the levers D, so as to substantially form a part of or serve as supplemental short arms of the lovers by means of latches F, pivoted to the short arms (1 of the levers, and adapted to catch over studs or projections g upon the arms or bars. By this arrangement the levers can be readily taken off to render the same more convenient for packing. The latches F are rigidly secured to the said short arms d, and are each provided with a small slot or approximately square opening, wherein the stud or projection g is caused to project, said stud or projection resting against the side and end walls of said slot or opening. The levers D are held in their normal or elevated position and the wringer-roll B in the retracted position shown in Fig. 1 by means of the coil-springs G, one end of each spring being connected to each lever of the treadle and-the other end to the upper forward end of the standards A.

The rear and front arms or legs of the standards A are provided with feet h h, arranged upon the inner sides thereof, the rear feet, h, being provided with open slots it, through which are passed T-bolts if, for securing the same to the base or platform H, upon which the wringer is mounted. By turning the bolts if so as to present their heads lengthwise to the lengths of the slots h in the feet h the latter can be readily lifted from the platform,

the mop when subjected to the squeezing or inorder to permit the tilting of the wringer, so as to cause it to rest sidewise upon the platw form, as would be the more desirable position in which to dispose or place it for shipment or packing. In order to permit the wringer to bethus tilted and placed, the forward l'eet, h, are made angular and separate from their legs, the latter being pivoted to the former, the flat or horizontal portions of the feet being bolted to the platform or base.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a mop-wringer, the combination, with the standards and rolls, of the treadle, the levers co'mprisingthe long and short arms, and the bars connected to the trunnions of one roll and to the fulcrumsof said levers, said bars and levers being connected together, substantially as shown and described.

2. In a mop-wringer, the combination, with the standards and .rolls of the treadle andlevers, the bars connected to the fulcrnms of the levers and to the trun nions or axes of one roll,

and the latches secured to the short arms of 25
