' BRUSH GUARD.

Application filed September 13, 1926. Serial No. 135,120.

This invention relates to improvements in brush guards forvacuum cleaners.

Heretofore, Vacuum cleaner brush guards have rested upon the lower surfaces of the i suction-nozzle and have thus formed an objectionable protrusion. It is one of the ob- 'ects of the present invention to provide a rush guard which will be flush with the lower surfaces of the suction nozzle, and

which-will thus in no-way interfere with the operation of the cleaner.

A further object of the invention is to provide a brush guard which may be readily removed when it is desired to clean. the 1!! brush.

'A further object is to provide a guard which will effectively prevent the rug from being drawn up into the suction nozzle during operation of the cleaner.

A further object is to provide a brush ard which will rest in recesses formedon t e lower surfaces of the suction nozzle, said recesses making it possible for the guard to be fiush with the lower surfaces and also as serving to keep the guard in itsproper lace.

With the above main and other incidental objects in view, which will appear as the description proceeds, the inventlon consists of the improved brush guard and its parts so and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the.

same parts in all of the views: Fig. l is a view of the lower surface of the suction nozzle of a vacuum cleaner shownghthe .brush guard in connection therewitp Fig. 2 is a section taken upon the line 2-2 of Fig. l;

of a vacuum cleaner showing the brush guard in attachment therewith;

Fig. 4 is a plan view of the guard detached from the cleaner, and

i Fig. 5 is a fragmentary rear ,view of the suction nozzle showing portions of the brush guard resting in the recesses.

Referring more particularly to the accomsaid suction nozzle'having recesses 7 on its described.

Fig. 3 is an end view of the suctionnozzle panying drawing, the numeral 6 designates the suction nozzle of the vacuum'cleaner,

lower surface, and front and rear longitudinally extending ribs 8.

The brush guard proper comprises a longitudinal rod 9 and a plurality of U-shaped members. The U'-shaped members comprise intermediate transverse portions 10, having bent end portions 11 attached to the longitudinal rod, and hook portions 12 for engaging one of the ribs 8 of the suction mouth.

To attach the guard, the longitudinal rod and the hook portions are snapped over the ribs 8 of the suction nozzle, and the brush guard is then moved sidewiSe to engage the intermediate members 10 with the recesses 7 of said suction nozzle. With the intermediate members resting in'the recesses, it may readily be seen that the guard will be flush with the lower surfaces of the suction nozzle and will therefore form' no hindrance to the operation of the cleaner. It will also be seen that the attachment or removal 'of the guard is very simple, the members 12 and 9 merely snapping over the ribs 8 of the suction nozzle. p Y L From the foregoing description, it may be seen that the brushguard is simple in c0n-' struction, strong and durable, efficient in operation, and well adapted for the purpose What I claim as my invention is:

1. The combmatlon with a vacuum cleaner casing provided with a downwardly opening elongated suction nozzle formed with lower front and rear longitudinally extending ribs and with transverse recesses in its front and rear lower edges, of'a removable brush guard therefor comprising a rod and a plurality of U-shaped members having their end portions attached thereto, the said guardextending around and en aging the outer front and rear portions 0% tending throu hsaid recesses, the recesses being of such epth that the U-shaped members of the'brush guard will lie flush with the lower edge surfaces of the suction nozzle.

2. The combination with 'a vacuum cleaner casing provided with a downwardly opening elongated suction nozzle formed with lower front and rear longitudinally extending ribs and with transverse recesses in its front and.

said ribs and exof U-shaped members having upwardly extel-mediate transverse portions extending tending end portions attached to said rod. through the recesses, the recesses being of v andhaving longitudinal hook portions and such depth that the lower surfaces of the 10 intermediate transverse portions-,the rod and brush'guard will lie flush with the lower the hook portions extending upwardly and ed es of the suction nozzle.

engaging the outer upper front and the n testimony whereof,I aflix my signature. upper rear portions of the. ribs, and the ins PATRICK H. ROBINSON.
