P RIEBEL. JR I VACUUM CLEANER Filed Aug. 50, 1929 INVENTOR. Freda/[ck R1856! Jn Patented Apr. 26, 1932 UNITED i mmnnnrcx mam. .13., or TOLEDO, onro, ,ASSVLGVNQB 'ro hrit wax steam-1i- I'LIANGE oonrona'rron, or TOLEDO, om'o',1a conrona'rron or .ngmwm vacuum Application filed August 30,1929. 7 Serial r ces-1165i This invention relates to vacuum cleanersv and has for an object a method of attaching a thread disturbing brush or other like element to the suction nozzle of such vacuum cleaner in such manner that the polished surface of such suction nozzle will not be marred in attaching and detaching such floor tool as has heretofore been the case in the use of such attachments.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of variousmechanical forms in which the principle of the invention may be used.

In said annexed drawings Fig. 1 shows in side elevation a vacuum cleaner of a common type embodying the principles of this invention; Fig. 2 is a front elevational view of a suction nozzle showing a floor tool attached thereto; Fig. 3 is a vertical sectional view along the lines 3-3, Fig. 2; Fig. 4 is a fragmentary bottom view of Fig. 2 and Fig. 5 is an isometric pr.o]ecti0n of the spring clamp used in attaching the floor tool to the suction nozzle.

Referring more specifically to the drawings and especially Fig. 1, the vacuum cleaner here shown is of the usual type having a motor element 1, an air filtering and dust collecting element 2, suction chamber 3, tubular handle 4, and suction nozzle 5. The suction nozzle:

5 shown more specifically in Fig. 2 has supporting wheels 6 secured thereto by means of wheel mountings 7 and 8, said wheel mountings being more fully described in my coending application filed February 27 1929 rial No. 342,979. Attached to the front 0 said-suction nozzle 5 is a floor tool 9, said floor tool being composed of a flexible element 10 and a brush securing element 11. Sad flexible element 10, which is usually felt or other they secure may-be attached to such nozzle .ed es tot and are secured in the retaining position shown in Fig. any. means of; a plurality of bolts 13 extending therethroughand securedby nuts 14. The securing bolts 13 adjacent to thevendfofsaid floor .tool also secure the spr ng clip members 15 tosaid floor tool. The spr ng clipmember 15 has an. aperture16 formed therein,-;,for engagement with the securing bolt 13, and bein secured to thefloor tool by means of this bo t alone, is permitted to rotate about said retaining bolt 13. Ito-- tationof'the spring clip member 15.with respect to the floor tool permits the floor tool to be attached to the suction noz'zlewith eitherthe brush, or the flexible edge in .the. .downward, direction. I The-spring clip15 has its lower end l7 bent in'a substantially U-shape to present an engagingmeans for thes ring: clipin the, aperture 1 8 formed therefor 1n the lower face of the suction nozzle as most clear- 1y shown in Fig. 4. Adjacenttheupper end of the springlclip 15, an aperture19 isformed to engage t e boss 20-on the upper. face of the suction': nozzle 5.. lThe. boss v20.fo'r retaining the spring clip in operative position is preerably-hemispherical inform and of greater diameter than the aperture 19 formed therefor in the-springiclip 15, j r The diameter of said -boss-20zbeing greater. than the di-- ameter of said aperturef'19' prevents the spring clip, from coming-in contact withthe polished surface :of the "suction nozzle 5,

thereby preventing the polished surface ;from becoming marred when such spring cli is attached and detached from such nozzle. he boss '20 -may'preferablybe the head of the screw employed'in this type of nozzle to securethe wheel mountings 7 and 8 in the sockets formed'therefor nozzle5;

,; It will .be :seen that a floor tool may be attached to -*a-,..suction nozzle by-means of a" spring clip .withoutin any way marring the highly po ished surface which is'common to such suction nozzles. Also, bya mere rota-" tion" of the spring clips, the'floor tool which so as to plresent either of its longitudinal-- in the end of suction e surface to be either cleaned' j it I Other, modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or thedequivalent of such stated means be emp therefore particularly point out and distinctl claim as my invention 1. he combination with a suction nozzle, of a floor tool, a reversible clip for attaching said floor tool to said nozzle including a member to engage the nozzle from below, an aperture formed near one end of said clip, and a boss on the upper side of said nozzle to secure said clip, said boss having a reduced upper end to engage said aperture in said clip and secure it out of engagement with the surface of the nozzle.

2. The combination with a suction nozzle, of a floor tool, a reversible clip attached to said floor tool for securing said tool to said nozzle, an aperture formed near one end of said clip, a recess in the lower face of said nozzle adapted to receive the other end of said clip, and a boss on the upper surface of said nozzle, said boss being hemispherical in shape'and of a larger diameter than the aperture in said clip.

13. In combination with a suction nozzle provided with a boss on its upper surface, a floor tool, a clip attached to said floor tool for securing said tool to said nozzle including a lower member to engage said nozzle from below and an upper member formed to receive a portion only of said boss whereby the clip will be supported by the bossout of contact with the upper surface of the nozzle.

4. In combination with a suction nozzle provided with a hemispherical boss on its upper surface, a floor tool, a clip attached to said floor tool for securing said tool to said nozzle including a lower member to engage said nozzle from below and an upper member formed to receive a portion only of said boss whereby the clip will be supported by the boss out of contact with the upper surface of the nozzle.

5. In combination with a suction nozzle provided with a boss on its upper suface, a floor tool, a clip attached to said floor tool for securing said tool to said nozzle including a lower member to engage said nozzle from below and an upper member formed to receive a portion only of said boss whereby the clip will be supported by the boss out of contact with the upper surface of the nozzle, said clip having at its opposite end a hook, and a recess in the lower face of said nozzle adapted to receive said hook.

6. In combination with a suction nozzle provided with a boss on its upper surface. a floor tool, a clip securing said floor tool to the nozzle, including a lower member engaging the nozzle from below, anintermediate porermost portion said lowermost portion being formed to receive said boss.
