1 Claim.

Our invention relates to brush holding clamps and more particularly to a device to be used in conjunction with scrub brushes, floor brushes, waxing and polishing brushes and the like. Certain objects are to provide a means for attaching a handle to a brush to allow the brush to be operated from a standing position, making the brush easier to use and eliminating the fatigue and inconvenience of the user getting on their knees to scrub, dust, wax or polish. Further objects of the invention are toprovide simple and eificient means for attaching the brush to the holder whereby the brush may be replaced when worn or whereby the device may be used in conjunction with any of a set of several brushes if so desired, and quick means of changing from one brush to the other. Another object is to provide means for reversing the brush when worn on one side, thus greatly increasing the life of the brush. Another object is to provide a projecting means on the-clamp that prevents the brush from twisting, thus requiring but one means for attaching the said clamp to the brush. A still further object is to provide a clamp that can be used on rectangular brush blocks avoiding the expensive oval block previously used. By using the flat brush block, material saving can be made in the manufacture.

With the above and other objects in view which will appear as the description proceeds, the invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompaning drawing, wherein:

Figure l is a general view in perspective showing how the device is used to attach a handle to a brush;

Fig. 2 is an enlarged detail view in perspective of the device; and

Fig. 3 is a View in longitudinal vertical section taken on a broken line 3-3 of Fig. 1.

Referring to the drawing throughout which like reference numerals indicate like parts, the device which is preferably made of sheet metal, comprises a horizontal fin portion 5 that is adapted to fit flatly on the back of a scrub brush or the like, designated by the numeral 6. A vertical downward projecting portion 7 integrally joining said fin at right angles thereto and adapted to fit flush against the side of the brush as shown at 8, is formed on the rear side of the fin portion 5. This allows the device to fit snugly and firmly onto the brush as will be understood.

Rearwardly of the downwardly projecting flange portion 7, the metal or otherwise extension of the fin 5, is bent to form an upwardly slanting tubular member 9. As clearly seen from the drawing, this member is adapted to hold a handle 10 which is placed within said member and retained therein by means of a pin 11 placed through holes 12 in .the aforesaid member. Said holes register with a hole 13 in the lower extremity of the handle 10.

To provide means for rigidly and securely clamping the device onto the brush, a longitudinal slot 14 extending from where the tubular member 9 merges into the horizontal fin portion 5 to the forward edge of said fin, is cut in same. This slot receives a carriage bolt 15 or the like, which is secured in the center of the back of the brush 6, and whose extremity projects up through said slot, and is provided with a wingnut 16, Upstanding bosses 17 are formed on the sides of the slot 14 so that as the wingnut is tightened down it will engage these bosses, as shown most clearly in Fig. 3, drawing the downwardly projecting flange portion 7 firmly against the side of the brush as it clamps the horizontal fin portion against the top of the brush, thus holding same in secure engagement.

Important features of the device are that the brush may be easily installed and removed. This makes for quick and easy replacement of worn brushes. Also the device may be used with any one of a set of brushes, as for example in the refinishing of a floor it might be necessary to use a scrub brush, a wax applying brush, and a polishing brush, all of which may be used with the same handle by means of our device, eliminating unnecessary equipment and the added expense.

Having thus described our invention, it being understood that minor changes may be resorted to without departing from the scope and spirit of the invention, what we claim and desire to secure by Letters Patent of the United States is In combination with a brush, a brush holding clamp comprising an integral sheet metal body member consisting of a fiat horizontal fin portion having a longitudinal central open end slot therein, an upstanding boss formed in the metal on each side edge of the slot, a flange depending from the rear edge of the fin portion and arranged to embrace the upper rear edge portion of a brush, a rearwardly and upwardly slanting tubular handle receiving socket member extending from the central slot and from the rear edge of the fin portion and depending flange, a bolt arranged to pass centrally through a brush that is installed against the bottom of the fin portion with its side edge engaging the depending flange, said bolt passing upwardly through the rear end of the central slot between the tubular handle socket member and the two bosses on the edge of the slot, and a nut installed on the upper end of the bolt with its edges engaging said bosses whereby the depending flange is drawn tightly against the brush that is installed therein.
