SPECIFICATION forming part of Letters Patent No. 549,104, dated November 5, 1895. Application filed February 20, 1895. serial No. 539,082. (No model.)
To all whom it may concern.-
Be it known that I, ARTHUR M. 'BURNHAM, a resident of Gardiner, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Mop- XVringers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in mop-wringers, and more particularly to such as are adapted to squeeze the mop, one object of the invention being to so construct a mop- Wringer that it will not injuriously affect the mop, as is the case with mop-wringers employing rollers.
A further object is to so construct devices for wringing a mop that the compressor will be made to travel the major portion of its movement with the expenditure of a comparatively small amount of treadle-power and exert a maximum amount of pressure on the mop when the movement of the treadle shall have been nearly completed.
A further object is to provide means whereby a mop-wringer can be adjusted for different-sized mops.
A further object is to produce a mopwringer which shall be simple in construction, comparatively cheap to manufacture, and which shall be effectual in all respects in the performance of its functions.
WVith these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a side view. Fig. 2 is a vertical longitudinal sectional'view. Fig. 3 is a plan view. Fig. 4 is a view of a modification.
A represents a pail, preferably made angular in form with the upper edges of the sides rounded. Within the pail A a curved compressor-plate B, having a number of perforations a, is pivotally supported bymeans of a shaft I, mounted at its respective ends in the sides of the pail, the pivoted end of said plate being curved, as at b, concentric with the shaft 1. The compressor-plate B is adapted to act in conjunction with a fixed perforated plate 0 and with a sliding spring-sustained plate D to press or squeeze the water from a mop disposed between them, the shank of said mop being made of such form as to enter a slot 0, so as to permit the compressor-plate to engage the sliding plate and contract the space occupied by the mop. The plate 0 is secured betweenthe sides of the pail, so that its lower edge will be disposed in close prox- 4 imity to the curved portion 1) of the compressor B. The sliding plate D is made slightly curved and adapted to slide past and in close proximity to the upper edge of the fixed plate 0. A bar cl is secured transversely to the plate D near its upper edge and projects beyond the edges of said plate to produce lugs e, which enter curved elongated slots f in the sides of the pail, and any water which may find its way through these slots will be caught by small troughs g, secured to the sides of the pail, and by said troughs be reconveyed to the interior of the pail through the slots. The sliding plate D is also guided in its movements by means of curved guides h, secured to the sides of the pail. Said sliding plate is maintained in its normal position by means of a spring D, secured at one end to the bottom of the plate and at the other end to the upper edge of the pail.
The arms 'iof a treadlej are pivotally connected to the pail and between their ends are bent and provided with journals 70 for the reception of rollers 70'. The shaft Z, to which the compressor-plate is secured, projects at both ends' beyond the sides of the pail and at its extremities is provided with fixed arms m, made at their ends with segments m, having teeth m Between the arms on and the pail levers n are loosely mounted on the shaft Z, and each lever is provided with a perforated lug 0 for the reception of a thumb-screw p, by which to secure a block 1) thereto, said blockfhav ing teeth 19 to engage the teeth m on the segments m. I
If desired, the teeth 1%? of the segments may be made in the. form of ratchet-teeth and the toothed blocks displaced by dogs p maintained normally in contact with the teeth by means of a spring 10 as shown in Fig. 4. The levers n are curved and constitute a track on which the rollers 76 run, so
that when the treadle is depressed the levers n will be moved down and the shaft Zturned, carrying the compressor-plate B upwardly and compressing the mop between it and the plates 0 D, the water in the mop escaping through the perforations in said plates. A continued pressure on the treadle will cause the compressor to bear on the sliding plate D with such pressure as to cause the latter to move downwardly, thus contracting the space occupied by the mop and thoroughly wringing the water from the same. As soon as the treadle is released, the spring D will return the sliding plate D to its normal position, and the compressor-plate B will fall by its own weight to its normal position in the bottom of the pail.
It will be observed that the levers n are so made that in proximity to their inner ends, where they are connected to the shaft Z, their curvature is somewhat abrupt, as at 9 and that the curvature from the part 19 toward the free ends of the levers is of a less degree. It will be seen, therefore, that when the treadle is first depressed the compressor-plate will be moved quickly (and with little exertion on the part of the operator) toward the plates 0 D, and that when the resistance offered by the mop is encountered the rollers on the treadlearms will be 011 the long curve 19 of the lever and some distance from the fulcrum of the latter. As the pressure on the treadle c011- tinues the connection between the treadle and levers n moves away from the fulcrum of the latter, and the leverage on the compressorplate increases until the maximum amount of pressure on the mop is attained, when the treadle will be in proximity to the base of the pail.
In the use of mop-wringers of the class to which my invention relates, as they have heretofore been constructed, it has been necessary to withdraw the mop from the water in the pail and then place it in the wringing or squeezing device. \Vith my improved construction it is not necessary to withdraw the mop, but merely to raise it slightly, and thus the inconvenience of wholly withdrawing the mop is avoided.
By connecting the levers n with the shaft I, through the medium of the adjustable arms on, the device can be readily adjusted for mops of different sizes. The adjustment should be so made relatively to the size of the mop that the treadle can be depressed to the base of the pail, so as to derive the benefit of the fullest amount of leverage on the compressor.
My improvements are very simple in construction, comparatively cheap to manufacture, and effectual in all respects in the performance of their functions.
Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details of construction herein set forth; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
