MOP WRINGER Filed April 24, 1935 Hlll Iii"

INVENTOR .Ezms J Hoazvuxa BY A ATTQRZY Patented Aug. 24, 1937 UNITED PATENT QFFIQE Claims.

This invention relates to a mop wringer of the drain cup type, adapted to be mounted detachably Within a pail so that a wet mop when forced into the drain cup has the excess water removed 5 therefrom.

In former wringers of this type, the drain cup has been made of perforated sheet metal but the rough metal at the edges of the perforations has rapidly worn out the mop and since the perforations cannot be tooclose together without unduly weakening the remaining material of the cup, the total area of the perforations through which the water could escape, has necessarily been limited. Furthermore, since the cup is pref- 5 erably made of light sheet metal it is weakened by the numerous perforations therein and therefore, it does not have the desired degree of rigidity to prevent it fro-m becoming bent and distorted during use.

In accordance with one feature of the present invention, it is proposed to make a wringer with a drain cup of reticulated or wire screen mate rial, thereby affording a large total opening area for the escape of excess water. It is also proposed that the wringer cup be tinned or treated with molten metal so that the intersections of the wire forming the cup and the joints of the wringer are rigidly connected together, thereby providing a wringer of great rigidity and relatively light weight.

30 An additional feature of the invention relates to a mop wringer of the drain cup type which is inexpensive to manufacture and which is rigid and durable in construction.

For a clearer understanding of the invention, reference is made to the drawing, in which Fig. 1 is a vertical section of a mop pail and the mop wringer of this invention mounted on the rim of the pail in the normal position of use; Fig. 2 is a plan view of the mop pail with the present mop wringer mounted on the pail, the bail or handle of the pail being broken away; Fig. 3 is a fragmentary detail view of the mop wringer showing especially the combined clip and hook whereby the parts of the wringer are held together and whereby the wringer may be retained on the rim of the pail; Fig. 4 is a sectional view taken substantially on the line l-4 of Fig. 3, further indicating the construction of the combined clip and hook; Fig. 5 is a fragmentary detail view showing especially a side view of one of the clips for holding certain parts of the wringer together; Fig. 6 is a sectional view taken substantially on the line E-5 of Fig. 5 further il- 55 lustrating the construction of the clip and the manner in which it holds certain parts of the wringer in assembled condition; Fig. '7 is a detail View showing the manner in which the hook on the end of the resilient arm or bracket of the wringer engages the rim of the pail; Fig. 8 is a side elevation of a pail with a modified type of mop wringer mounted thereon; and Fig. 9 is a plan View illustrating this modified type of wringer also mounted on a pail, the bail of the pail being broken away. 10

Referring especially to Fig. 1, 5 designates a mop pail of the usual construction provided with a bail l9 and with a rim reinforced by having its edge 6 rolled over a wire ring 7. The mop wringer which is adapted to be detachably mounted on the rim of the pail includes a cone-shaped cup 8 formed of reticulated or wire screen material. The cup is reinforced by a circular channel shaped strip 9 of sheet metal, the free edge of g the cup being gripped in the channel space within the strip. It will be noted from Fig. 2 that the free ends of this channel strip are slightly spaced from each other at IU thereby allowing manufacturing tolerances which would not be acceptable if the free ends of the strip had to be in exact abutting relation. A bracket ll encompassing the major portion of the margin of the cup is fastened to the channel strip by means of clips l2 and the combined clip and hook l3 which grip the sides of the strip 9. This bracket is provided with slightly resilient, radiating arms l4, each of which terminates in a hook l 5 adapted to engage the rim of the pail. Each clip I2 comprises a piece of metal having a U-shaped portion 55 with one leg l6 thereof terminating adjacent or in engagement with the lower surface of the strip 9. The other leg of the U-shaped piece is of such length that it can be folded over as shown at ll substantially across the channel shaped strip 9. The combined hook and clip 13 is similar in construction to the clip l2 except that it is of a materially greater width than the clips IE to bridge the opposing ends of the strip 8 and is provided with a hook l8, intermediate of its side portions, adapted to engage the rim of the pail as best indicated at the left of Fig. 1. Clip 53 may be likened to two of the clips I2, joined together by the hook portion l8.

In manufacturing the wringer, the drain cup is pressed from a sheet of reticulated or wire screen material into substantially cone-shaped form and the free edge thereof is then trimmed to circular shape. The strip 9 is out to the proper length from flat sheet metal stock and is then bent into channel shaped, circular form in any 55 we1l-known manner. The bracket II which is made of rod stock, is cut to the desired length and is bent to substantially the shape illustrated in Fig. 2. The edge of the cup 8 is then sprung into the channel space in strip 9 and this cup unit thus assembled is then placed in a press whenever the sides of the channel-shaped strip are forced tightly into engagement with the margin of the cup. Thereafter the bracket is placed on the channel strip 5 of the assembled cup unit, both parts being positioned in a fixture and the clips iZ-l? and the combined clip and hook IS in their open condition are located in the fixture about the bracket l l and strip in the relation best illustrated in Figs. 4 and 6. The fixture and the wringer parts thus assembled are placed in a press (not shown) wherein the clips I2| 2 and the combined clip and hook [3 are forced to their closed position as illustrated to grip the bracket H to the strip 9 on the rim of the cup. Thereafter all of the wringer including the arms M are dipped into molten metal for tinning. This molten metal collects at the intersections of the wires of the cup and in addition it collects in the spaces between the margin of the cup and the channel shaped strip 9 as well as at the contacting portions of the bracket and the mentioned strip. Furthermore, this molten metal collects in the joints between the clips l2 and likewise in the joints between the combined clip and hook l3 and the channel shaped strip 9. By this construction an especially rigid wringer is provided and yet the perforations in the cup do not cut the mop during the wringing operation.

The wringer is applied to the pail by hooking the hooks E5 of the bracket it over the rim 6 of the pail at one side of the bail E9. The hook it on the cup is then sprung over the rim 6 of the pail at the opposite side of the bail from that previously mentioned, the resilience of the radiated arms of the bracket I4 permitting the wringer to be sprung on the pail in the manner just described. It should be understood that the diameter of the circle defined by the two hooks i5 and the hook i8 is less than the diameter of the circle defined by the outer edge of the rim 6. Thus the wringer can firmly grip the rim of the pail, and yet can be readily detached from the pail at will.

In Figures 8 and 9, there is illustrated a modified form of the invention in which the bracket [4 and the combined hook and clip IQ of the arrangement previously described has been replaced by two brackets 28 provided with radiating hook portions 2| by which the wringer can be hooked on to the rim t of the pail. Each bracket 29 has an arcuate portion 23 which is riveted or otherwise fastened to the rim 9 of the cup. It should be noted that each hook is provided with a reinforcing rib 22 to give strength thereto.

In this construction the hooks 2| are hooked over the rim of the pail and a portion of the cup between the brackets 20, rests against the inner surface of the pail 5, so that when a mop is inserted into the cup and when pressure is applied to the mop, the cup will be prevented from downward movement by the rim and by the inside surface of the pail. The remaining parts of the wringer and the pail are identical with the parts previously described and are identified by the same reference characters.

It will be understood that the present disclosure is merely typical of applicants invention and that there may be many modifications and variations thereof within the scope of the appended claims without departing from the spirit of the present invention.

What I claim is:

1. A mop wringer comprising a cone-shaped cup formed of wire screen material, a channel shaped rim grip-ping the edge of said cup, a bracket attached to said rim, said bracket encompassing a substantial portion of said rim, said bracket having laterally resilient radiating arms which project away from said cup and which are provided with hooks, and a hook mounted at that side of the cup which is remote from said radiatmg arms.

2. In combination with a pail, a wringer comprising a perforated cup, a hook attached to one edge of said cup, a pair of laterally resilient radiating arms attached to the opposite edge of said cup and terminating in hooks, the circle defined by said hooks having a smaller circumference than the outer circumference of the rim of said pail.

3.
