FRANK lV. TOI/VNF, OF BENNINGTON, VERMONT, ASSIGNOR TO ANNA E. TOVNE, OF BENNINGTON, VERMONT.
SPECIFICATION forming part of Letters Patent No. 697,223, dated April 8, 1902.
Application filed August 31. 1900. Serial No. 28,636. (No model.)
To all whom, it may concern:
Be it known that I, FRANK W. TOWNE, a citizen of the United States of America, and a resident of Bennington, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Mop -lVringers, of which the following is a specification.
This invention falls in that class of mopwringers in which the mop is wrung by clamping it between squeezingjaws, one of which reciprocates toward and from the other.
The improvements consist in making one of these jaws self-accommodating to the inequalities of the body of the mop as it is squeezed, so that if the mop as compressed between the jaws presents an uneven thickness to the jaws one of them can rock or turn on a pivot, so as to equalize the pressure, and thus dry all parts of the mop alike. This is accomplished in the manner hereinafter explained.
Another part of the invention consists in arranging the bars of one jaw so that they will be opposed to the spaces between the bars of the other jaw and in making these bars of V shape, with the sharp edges presented toward the mop; also, inproviding the swinging jaw with a device for setting the accommodating jaw wideopen to receive the mop when the swinging jaw is thrown back after use.
The drawings fully explain the invention, in which- Figure 1 shows an elevation of a vertical section of the wringer, taken on the line 5c @o of Fig. 2. Fig. 2 is a front elevation of the wringer. Fig. 3 is top plan View of the same. Fig. 4. is a diagrammatic view of a horizontal section through the jaws and shows the relative positions and shapes of the bars thereof. Fig. 5 shows one of the jaws hung on a universal joint or pivot, so as to be capable of an accommodating motion in all directions.
The frame of this wringer consists of two side pieces A A, the sides of which are perforated, as seen in Fig. l. These sides are united by the front E z' z' and have projecting hooks N on their rear edges, to which camclamps G are attached to engage the pail J to support the wringer therein. Each side has a depending leg,which extends down into the pail, to the bottom of which is pivoted a similar leg of the swinging jaw B, as seen at a. A lever-handle II is pivoted to the sides, as at ff, and is connected with the swinging jaw B by toggle-links L L, so that by swinging the handle forward the jaw is forced toward its companion jaw D. Between the sides A A the oscillating jawD is pivoted on the center p and has a limited amount of oscillation thereon, determined in this case by the top or bottom of the jaw striking the bars it' of the frame. In the case illustrated the jaw is hung on an axis of oscillation; but I do not confine myself to an axial connection, as the jaw may be hung on a universal pivotal connection, as shown by the modification illustrated in Fig. 5. The latter construction allows the jaw to rock in all directions about its central pivot, and it is thus able to accommodate itself to any possible inequality in the thickness of the mop which may be presented to its action.
In the modification shown in Fig. 5 the rocking jaw D is provided on its back side, at or near its center, with an eye 19', with which an eyebolt e connects, which bolt passes through a cross-bar E of the frame A and is held firmly in place by the nut e". This, beinga universaljoint,allows the rocking jaw D to oscillate on its center in any direction.
The jaw B has a perforate bottom plate C attached thereto, and in action this bottom slides under and close to the under edge of the jaw D, as in Fig. 1. On its front edge is one or more hooks c, which are adapted to engage the lower edge of the jaw D whenever the bottom of that jaw is thrown forward and on the back stroke of the handle, as in the act of releasing the mop after a squeeze, to rook that jaw into its proper position to take in the mop when required to be wrung again. This position of the accommodating jawis indicated by the dotted lines in Fie. l.
In my improved wringer I have arranged the parts so that the jaw nearest the staves of the pail is the swinging jaw and its working movement is toward the center of the pail. If the other jaw is made the swinging member and its working movement is toward the staves from the center, the liability of IOO the squeezing action to force the jets of dirty water over the top of the pail is much greater. Besides, experience in use has demonstrated that the whole apparatus is much more effective as here arranged than with a reverse arrangement. A much more effective action of the rocking jaw is secured by pivoting it to a stationary part of the frame of the wriuger thanbypivotingittotheswingingjaw. When the rocking jaw is also made the swinging member with which the handle connects, all the loose or wa-bbling parts, being harnessed together and working against an absolutely rigid jaw, work badly on account of cramping and jamming in their action. A
The vertical bars b b and d d of the jaw possess special advantages for effectually expressing the Water from the mop by reason of their V shape and their alternate arrangement of bars and spaces. This V shape and arrangement of the bars of one jaw opposite the spaces between the jaws of the other jaw I regard as both new and highly useful.
I therefore claim as my invention, and desire to secure by Letters Patent, the following:
l. In a mop-wringer, the combination with a rigid frame having perforate Walls, of a rocking jaw pivoted in said frame on the side nearest the center of the pail, on a single center of oscillation; a swinging jaw pivoted to the frame on the side toward the wall of the pail, and an operating-handle connected with the frame having an operative connection with said swinging jaw, substantially as specified.
2. In a mop-wringer, the combination with a rigid frame having perforate walls, of a rocking jaw pivoted in said frame on the side nearest the center of the pail, on a single center of oscillation; a swinging jaw pivoted on the frame on the side toward the wall of the pail, having a perforate bottom attached thereto, and an operating-handle connected with the frame having an operative connection with said swinging jaw, substantially as specified.
3. The combination in a lnop-wringer of a frame, two squeezing-jaws mounted in said frame one of which is movable, both of which jaws are provided with grid-bars having V- shaped faces and so disposed that the faces of the bars of one jaw shall oppose the spaces between the bars of the other jaw, and means for actuating one of the jaws, substantially as specified.
4. The combination in a lnop-wringer of a frame, a movable compressing-jaw mounted in said frame and means connected therewith for actuating the same, an accommodating jaw pivoted on the frame on a single center of oscillation, and a device intermediate said jaws and actuated by the back stroke of the compressing-jaw for setting the accommodating jaw to its most open position to take in a mop, substantially as specified. y
5. The combination in a mop-wringer of a frame and two squeezing-jaws supported therein, one of which is pivoted on a single center of oscillation and the other is arranged to reciprocate toward and from the first, both of said jaws having parallel V-shaped bars so ldisposed that the faces of the bars of one jaw shall oppose the spaces between the bars of the other, the reciprocating jaw being provided witha horizontal perforated plate which forms the bottom of the inclosure which receives the mop, and a retracting-hook connected with the reciprocating jaw adapted to coperate with the bottom edge of the oscillating jaw to open the jaws to their widest capacity on the completion of the back stroke of the reciprocating jaw, substantially as specified.
