MOP-WRINGER.

To all whom it may concern:

Be it known that I, MILTON E. DAVIS, a citizen of the United States, residing at Canastota, in the county of Madison and State of New York, have invented certain new and useful Improvements in MoplVringers, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved mopwringer, and I declare the following is a full, clear, concise and exact description thereof, sufiicient to enable one skilled in the art to make and use the same, reference being had. to the accompanying drawings in which like reference characters refer to like parts throughout.

One of the principal features of the invention is that the device is constructed on such principles that itsoperation is equally eflicient in wringing mops of different sizes. This is accomplished by providing in the series of members by which compression is effected a resilient member, or members, whereby the compression is, beyond a given point, of a yielding nature. So that if the mop is of large size the latter part of the movement by which pressure is applied is made against the parts of the mechanism which have the qualities of resiliency, while in the case of a small mop the same parts are effective to compress it in the smaller space which it occupies.

There are various other features, such as the construction, mounting and connection of the moving presser, the presser-back, the bottom and other parts.

In the drawings Figure 1 is a perspective view of one style of machine, one of the side frames being removed. Fig. 2 is a detail view of part of the side frame of Fig. 1. Fig. 3 is a perspective view of a modified form of construction of certain parts. Fig. 4. shows a detail of a part of Fig. 3. Figs. 5 and 5 are views of the modified constructions. Fig. 6 shows a construction with two springs. Fig.7 is a side view of a further modification, of which Fig. 8 is a top view. Fig. 9 is a detail view of the back and presserback. Fig. 10 shows a style ofconstruction having arms disposed at different angles on the shaft. Fig. 11 shows in detail a form of connection between two parts. Fig. 12 shows a clip referred to in the description. Fig. 13 is a detail, parts being broken away Specification of Letters Patent.

showing pins on the presser and presserback engaging in the bottom board.

It is to be understood that various of the modifications shown can be grouped in such combinations as may be desired.

Referring to the figures in detail, A, A represent side frames or brackets, preferably of metal, having means whereby to support the wringer on a pail or tub, such as prongs A.

B is the back, with which the brackets A are firmly connected by suitable means. At the opposite or front part of the brackets they are sufficiently secured together by shaft C which has each end mounted on one of the brackets, though other or additional means may be employed for the rigid connection of the brackets. The back B has what may be termed a presser-back, or a false-back, 1, loosely mounted on it with resilient members, such as springs 2, between the two whereby the false-back yields to pressure of the mop, thus increasing the resiliency of that pressure whereby the de vice is adaptable to various conditions. The springs may be secured to the back and the presser-back to afford the sole support of the latter. If desired, however, there may be other or additional means used, such as pins 3, Fig. 9, shown as mounted on the presser-back and extending through bores therefor in the back.

The presser-back is designed to form one of the boundaries of the space in which the mop is compressed and, therefore, extends a sufiicient distance toward the top of the device and toward the side frames. It is provided with leakage bores, as indicated by 10. It is also extended nearly to the bottom piece D. This bottom piece may be mounted in different ways. In Fig. 1 it is shown having pins 4 supporting it on the brackets A, though screws or other suitable means may be provided therefor. This holds the bottom rigidly in place. I11 Fig. 3, a single pin, screw or the like, 5, is shown, holding it at one edge to the brackets so that the other edge can tilt, being held by any suitable means, such as pins, 6, or the like, extending through slots 7 in the brackets. If preferred, a clip 8, Figs. 9 and 12, may be fixed to the bottom or the back, the other end loosely engaging the other member to permit the swing of the bottom. The bottom may be of wood or metal, as also other parts,

provided with apertures, such as slots 9, presser may be extended to strengthen it Fig. l, for proper drainage.

The presser is shown by E and forms the side of the compression space opposite the presser-back l and extends a suitable distance toward the sides, bottom and top. It is actuated by mechanism to be described, by which it is partially supported in place. A variety of means are shown for guiding and holding it. In Fig. 1 slots 9, or certain of them, provide ways for the travel of fingers 11, certain of which may be headed, as seen at 12, and which guide the presser in its movement and hold it in place. The fingers which are not headed are such as are shown in Fig. 3. Such pins 12 may also serve to support the bottom D in the construction wherein the presser is held up by pins 13 traveling in slots 14 in the brackets, Fig. 8. The pins 12 afford a hinge-like connection between the presser and the bottom, allowing the one to slide on the other, one or the other being supported in some manner such as indicated in the different illustrations, the design being to allow the presser freedom of tilting as it moves to and fro while the bottom may also be mounted to allow it some freedom of movement. In case the presser is suitably confined or guided, as by pins 13, it is not necessary to use the headed pins 12 for such purposes, the bottom being given some other suitable support. Such pins, however, have the further function of preventing the mop from being wedged between the bottom and the lower edge of the presser as it is moved to and fro. This requirement is also met by pins 11 in the presser and the presser-back, which need not, however, extend through the bottom but only into slots 9 out part way through, as seen in Fig. 8. Such pins may be used in the form shown in Fig. 1 being intermediate of pins 12 and traveling in slots 9 and extended as far therein or therethrough as neeclful. The presser also has leakage bores, such as 15 and the slots 9 should also be cut through at points for drainage, as at 9 It will thus be seen that I have provided a space for the mop, with a bottom and sides, severally provided with drainage openings, mounted in a more or less flexible connection, the sides being adapted to tilt in adapting themselves to the mass to be compressed and so interfitted with the bottom as to prevent wedging where that is liable to occur.

The shaft C is suitably mounted in the frames or brackets. It is provided with one or more arms, 20, suitably secured thereon or integral therewith and properly positioned. At 21 is shown one or more links connected with the arms, the other end bearing on the presser which has a cleat, or cleats, 22, adapted to receive and hold the links. The cleats 22, being secured to the and distribute the strain of compression. The cleats each have an eye 23, the links being headed to slip into the eye, and to be held therein when the parts are assembled.

An important feature of the invention is that between the shaft 0 and the presser I and as part of the mechanism which operates the latter, there is a resilient member, or a plurality of them, such as the springs shown, the arm and link being connected in any suitable sliding engagement, so that when pressure is applied to the mop, especially at the latter part of the stroke, the strain is partly taken up by the resilient member and the leverage is increased toward the end of the stroke. The first part of the stroke earries the presser to or toward the mop without any change of the arm and link from their extended position. \Vhen resistance is met one slides on the other against the force of the spring, which is strong enough to press the water from the mop, while the spring obviates the jar and strain which would be felt in the machine and by the operator in case there was an unyielding connection of the parts of the operating mechanism. The construction of these parts is shown in a variety of forms. ln Fig. .l the shaft has two arms. 20, each slotted. the links 21 being suitably engaged therein, 24' being a coil spring on each arm against which the link bears when the shaft is swung by the handle 25 to advance the presser. In this figure is shown an additional resilient member, which may be used as alternative to the other means or in conjunction with either of them. It consists in 'ay 21' on each side adapted to carry block 27 in which the shaft is supported. The. way is slotted at 28, Fig. 2, to allow travel of the block. Between the block and the head of the way is the resilient member, here spring 29, with screw 30 with collar 31 hearing against one end of the spring whereby to regulate the tension of the spring. In Figs. 3 and 1 the arms 20 are closer together and a cross-head 10 is mounted on them, the link 21 being connected to the cross-head to allow necessary play of the parts when the shaft is rotated. in Fig. 5 the arm 20 is shown as slotted and provided with the spring 21", while in Fig. (3 arm 20" and link 21 are both slotted (with a bolt +13 connecting them) and shown with a spring 21 on each. In Fig. 7 the arm 20 and the link 21 are shown as having a collar and 4-1 each with a spring 24, the collars being pivotally connected, for instance, to allow adjustment, each collar bearing against a spring which is carried by its respective member, each collar being adapted to slide on its carrying member (arm or link.) In Fig. 10 the shaft C is shown with arms 20 at different angles on the shaft with two links 21 extem ed to the lower part of the presser and the link 21 from the other arm 2O extended to a point near the upper part of the presser. Each arm is shown with spring 2& as before. In this style the top opens a greater distance than the bottom, making it convenient for inserting the mop. The pressure is also equalized between the arms adapting the presser to crowd against the mop more in conformity to its bulk as it lies between the pressing members. Of course, these are merely illustrative of different methods of forming the operating parts and selection may be made of general features, in various combinations, or equivalent devices may be employed.

It will be seen that in this device I provide members for crowding the presser against the mop which have a sliding connection, so that as the presser approaches the. end of the stroke where the greatest pressure is necessary, the leverage is increased, the connection between the members, which is the bearing between them, changing its position so as to give greater leverage at the handle for exerting necessary pressure. Soon after their bearing point moves from its normal position, one member (or set of members) bears against a spring (or both do as the case may be). In case a large mop is used the compression begins at an early moment, the presser adapts itself (also the presser-back) to the shape of the mass to be compressed, and as the presser is advanced the power of leverage becomes greater and soon one member bears against a spring which prevents the presser from falling back from the work by the bearing between the arm and the link at once sliding to the limit, but as full a stroke as necessary is allowed. The strength of the spring is great enough to effect the wringing of the mop at any point, when the necessary pressure is applied. In case of a small mop the arm and link swing a greater degree before the presser bears on the mop or the bearing point is changed. Vhen pressure is begun, however, the bearing point gradually changes as the spring yields in exerting pressure on the mop according to its tension or stiffness. Adequate pressure can be made on either a large or a small mop, the presser and presser-back adapting their planes, respectively, to the form of the mass.

In the form shown in Fig. 10 it is intended that the construction shall have a plurality of such appliances cooperating to effect continuous and distributed pressure.
