Application filed August 3G, 1912. Serial No. 717,949.
To all? who/m. t may conc-em: l
ijeit known that. l, Geenen B. STEWART, a
citizen of the United States, residing atA Pittsburffli, in the counts1 ofAllegheny and State of Pennsylvania, have invented a newl and uso/fr Nozzle for Vacuum-Cleaners, of
Weich lthe following is a specification.
The present invention relates to improvements in nozzles for Vacuum cleaners, the
present structure being especially designed nozzle'is placed into act-ire' relation thereto.
With' the. foregoing. and other objects in View which will appear as the description proceeds, the invention resides in the com'- bination and arrangement. or part-s and 1n the details of construction hereinafter dei' scribed and claimed, it being understood that changes in the precise embod1n1e;':t of the invention herein disclosed can be made Wit -in the scope of what is claimed Without departing from the spirit of the invention.
In the drawings-Figure l is a side ele#l portion or member. FigS is a plan View of the exchange board engaging member.
leferring'totlie drawings, the numeral l designates the nozzle head which is adapted to have the 'end 2 connect-ed to a suction hose (not shown), and carri `l by the head at diametrically opposite points aretlie two arms 3 carrying each guiding sleeved. Mounted forv sliding movement in the sleeves 4 are the two rods Eeacli4 one of'whicli is provided Withfthe limiting head and lia.Q its other end connected to the lug 6 of the exchange Vboard engaging iiieinbei' or mouthpiece 7.' This is preferably madeot an invsulating material .so as to avoid any short circuiting When-used in connection with the exchange board.
The mouth-piece 7 is provided with a plurality of inlet apertures 8 and in order to tliig. .I
` provide a means to prevent injury to the exchange board and :it the same time to provide a chamber upon. the exchange board engaging side of the mouth-piece 7, a rim 9 of felt or rubber is carried as shown.
In order to hold the mouth-piece 'i' away from the nozzle l, as shown in Fig. l, the coiled springsr l0 are disposed upon the rods and engage atone end the sleeves' 4 while at the other end the lugs 6,
When it is desired to operate the present device, the mouth-piece is presented to the exchange boardwitli the rim 9 thereagainst 'and by a slight pressure uponthe nozzle 1, the two springs 10 are compressed asshouin' in Fig. 2, until the nozzle l engages the mouth-piece 7, thus confining the suction action tothe perforated portion of the mouth piece 7 and thus only acting upon the exchange board when the nozzle l' is pressed inoutlilpiec-eis first positioned upon-the -exchange board and nov suctionl action is perthe position assliown in Fig. 2. 'It is also evident that by reason of the springs 10 the release of the nozzle 1 will permit of an automatic adjustment of' the members from the position as shown in Fig. 2 to that shown in F 1, thus automatically relieving the mouth-piece 7 of any suction .action when the tool is being removed or released.
W'liat is 'claimed is:
1. Ina tool for vacuum cleaners, the conibination of a nozzle having an inlet -and an to 'and from the inletof said nozzle, and 'resilient means to normally hold the mouthpiece away. from said inlet.
2.. In a tool for vacuum cleaners, the coinbination of a nozzle haring an inlet and an outlet, a perforated mouth-piece, and means carried by the nozzle and mouth-piece ior resiliently connecting the inoutl1-piece to the nozzle for movement to and-from the inlet thereof.
In -a tool for 'vacuum cleaners, the couibination of a nozzle i: ing an inlet and an outlet, a, plurality' of guiding arms carried by said nozzle, a mouth-piece, a plurality of rods slidably mounted in said arms and con'- a spring mounted upon each rod for resiliently holding the inoutli piece away from the -inlet'end .ot the nozzle.
