DUSTPAN Filed Nov. 23, 1937 ATTO R N EYS Douglas Blake Patented A ..23, 1940 UNITED STATES ATEN OFFICE 1 Claim.

This invention relates to dustpans and has for 'an object to provide a dustpan which will eliminate stooping.

A further object is to provide a dustpan having a rotary brush disposed at the entrance opening in the front wall of the pan, and having novel hollow handle inclined upward from the pan at a convenient angle for manipulating the pan without the operatorbending over, the handle performing the additional function of housing the brush operating mechanism.

A further object is to provide a dustpan of this type which may be formed of a few strong simple and durable parts, which will be inexpensive to.

manufacture and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts herein- .derstood that various modifications may be resorted to within the scope of the'appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specifiation,

Figure 1 is a side elevation of a dustpan constructed in accordance with the invention, parts being broken away to show the construction.

Figure 2 is a plan view of the dustpan shown in Figure 1.

Figure 3 is a detail sectional view showing the dust entrancexopening in the front of the pan.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, the dustpan comprises a casing having a bottom I0, side walls II, a front wall l2, and a rear wall l3. The front wall is provided witha dust entrance opening [4 in the The bottom 10 is beveled, as shown at l5, at the 4 ure 1, which is journaled in bearings [8 that may be secured in any preferred manner to the side walls of the dustpan. The rotary brush pro-,

jects with its rear side into the dust receiving opening l4 and the top edge of the dust receivin opening engages the brush to clean the brush of any accumulations of dust thereon.

A guide tube 19 is secured to one side wall ll of the casing and inclines upwardly and rear- 5 wardly. A cylindrical metal handle 20 is received in the tube and is split longitudinally as after fully described and claimed, it being unnature of a long slot at the bottom of the wall.

shown at 2| for a portion of its length to re-- ceive guide pulleys 22 over which a cable 23 is trained. One end of the cable is trained over a pulley 24 secured to the end of the shaft 11 of the brush. The other end of the cable is trained 5 over the uppermost pulley in the handle and the shaft 25 of this pulley projects out of the handle I 20 and is equipped with a crank handle 26 The crank handle 26 is located at such heights as to be conveniently operatedby the operator Without 10 stooping when the operator grasps the crank handle-in one hand and grasps the grip 21 of the dustpan.

A dust outlet opening 28 is formed in the rear wall l3 of the dustpan, as best shown in FigureZ. 15 A closure 29 for the opening is slidably fitted in guides 30 carried by the side walls It. A strap grip 3! is secured to the outer face of the closure for raising and lowering the closure. A leaf spring 32 is secured to the inner face of the 010- 20 sure and bears against a projection 33 on the ing ner face of the rear wall [3 to yieldably hold the closure in open or closed position. The leaf spring is provided with a hook 34 at the upper end which may be utilized if desired to manipulate the closure. r v

By referring to Figure 2 it will be seen that "a brace 35 is secured at the lower end to the outer face of the side wall I l' opposite the sleeve [9, as best shown in Figure 1. The brace inclines upwardly and rearwardly toward. the dustpan 30 handle 23 and is secured at the upper end tothe handle. This brace coacts with the sleeve IS in securing the handle to the dustpan.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is: y The combination with a dustpan casing having an opening in the front provided with a cylindrical brush having anp-ulley at one end, of a I guide tube secured to one side of the casing and inclined upwardly and rearwardly, a cylindrical metal handle received in said tube and split longitudinally at the top and bottom for a por-' tion of its length, guide pulleys in said split portion of the handle, a drive cable trained over the guide pulleys and exposed through said split, one end of the cable being trained over the pulley on the. brush, the other end of the cable being trained over one of the pulleys in the handle, and a crank handle connected to the last named pulley for driving the cable and the brush.
