Patented June 26, 1934 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to improvements in floor Squeegees, and it consists in the combinations, constructions and arrangements hereinafter de scribed and claimed.

An object of my invention is to provide a floor squeegee which is an improvement over my Patents'No. 1,497,933 issued June 17, 1924, and No. 1,789,636 issued January 20, 1931. In my earlier patented device I showed a squeegee having a curved lower edge for causing the squeegee to tilt forwardly when moving over the floor. In my later patent the frame of the squeegee is tilted forwardly for inclining the rubber-wiping member at the requir d angle. In the present device I provide a frame with two parts, each being formed with a rib for reinforcing the frame and for also gripping a rubber-wiping member. The ribs grip the wiping member adjacent to an edge, and this permits a member of less width to be effectively used than is required in the other two forms of squeegees above referred to.

Other objects and advantages will appear as the specification proceeds, and the novel features of the device will be particularly pointed out in the claim hereto annexed.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of the device,

Figure 2 is a section along the line 2-2 of Figure 1,

Figure 3 is a section along the line 33 of Figure 1,

Figure 4 is a section along the line 44 of Figure 1,

Figure 5 shows a straight squeegee,

Figure 6 shows a squeegee curved slightly in the direction of its length,

Figure 7 is a front elevation of a modified form of the device,

Figure 8 is a section along the line 8-8 of Figure 7, and

Figure 9 is a top plan view of Figure 7.

In carrying out my invention I provide a frame consisting of two parts 1 and 2. The frame may be straight as shown in Figure 5 or curved in the direction of its length as shown in Figure 6. The upper edge of the parts 1 and 2 are formed with reinforcing ribs 3 and 4, and these contact with each other for forming a bead that extends the length of the frame.

The bottom edges of the parts 1 and 2 are formed with ribs 5 and 6 for reinforcing the frame and also for engaging with a rubber-wiping member 7 adjacent to the edge 8 of the member. The provision of the ribs 5 and 6 makes it possible to maintain a firm grip on the member 7 even though gripping the member near the upper edge. This results in a saving of material in the wiping member. Furthermore, the member 7 can be more readily secured in place, because less of it has to be moved between the parts 1 and 2.

Bolts 9 removably secure the parts 1 and 2 together, and certain of these bolts secure hinge members 10 to the frame. A forked portion 11 of a handle 12 is pivotally secured to the hinge members 10 and connects the floor squeegee with the handle. In Figure 3 I show the handle 12 and illustrate how the forked portion 11 is secured to the handle by a ferrel 13.

Guards 14 of the shape shown in Figure 4 are secured to the ends of the frame and have rounded outer portions for protecting the edges of the frame.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The squeegee is used in the ordinary manner, and when it is desired to change the wiping member 7, the bolts 9 are loosened, which permits a new wiping member to be substituted for the old one. The bolts are then tightened and the device is ready for further use.

The lessening of the width of the member 7 provides a squeegee which is lighter in construction.

In Figures 7 to 9 inclusive I have shown a modified form of the invention. In this form of the device the parts and 26 corresponding with the parts 1 and 2 are provided with lips 27 and 28 that depend below the ribs 29 and 30. I have found that when two wiping members 31 and 32 are disposed together and gripped by the beads 5 and 6, they will spread and extend in angular directions from the line of gripping when the bolts 9 are tightened. The lips 27 and 28 prevent the spreading in the modified form of the invention, and the bolts 33 may be tightened for gripping the members 31 and 32 in the manner shown.

The frame of the floor squeegee in the modified form of the invention is reinforced by a flange 34 that is integral with the part 25. This flange exiends at right angles as shown in Figtu'e 8 and acts as a reinforcing rib for the squeegee frame. This makes the device more rigid in construction.

The handle 35 (see Figure 7) carries a sleeve 36 that has tubular portions 37 and 38 for receiving L- shaped rods 39 and 40. The free ends of these rods are rotatably disposed in aligned sleeves 41 and 42 formed in a bracket 43 that is secured to the part 25.

The modified form of the invention may be provided with the guards 14 in the same manner as the form shown in Figure 1.

The lip 2'7 preferably extends at an angle with respect to the plane of the part 25 (see Figure 8) and this causes the edge 44 to clamp the strips of rubber 31 and 32 between the edge 44 and the inner face of the lip 28. The rubbers 31 and 32 are bound more tightly along the edge 44 than along the lower edges of the rubber strips. In fact, the lower edges 45 and 46 of the lips 2'7 and 28 do not appreciably bind against the rubber strips 31 and 32. In this way the rubber strips are prevented from extending away from each other at their exposed edges.
