Application filed April 1, 1912. ScrialNo. 687,807.

To allie/wm t may concern Be it known that I, EUGENE-Correr, a citizen of `the United States, and/ a resident ot' the lcity of Bloomington, county of Mc- Lean, and Statef Illinois, have invented certain new andA useful Improvements in Combined Carpet-Sweepers and Vacuum- Cleaners, of which the following is a specification.

My invention relates lto improvements in combined carpet jsweepers and vacuum cleaners, and the object of this improvement is to provide a device of the character described which will -be simple 'of construction and elicie'nt in operation.

The invention consists inthe combinations and arrangements of parts `hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of avhicli Figure 1 is a plan view ot my device with thev cover portion'removed, and, Fig. 2 is a this specification, and in vertical section of my device taken lon line 2 2 in'lig. 1.

Like numerals of reference indicate like parts throughout the drawings.

The preferred' form of construction, as

" illust-rated in the drawings, comprises a casing 5 carriedby driving wheels 6 mounted on shafts 'i' and journaled in bearings 8, which bearings are formed with a greater vertical diameter than'horizontal diameter to allow a slight-vertical movement of said casing 5. Springs 9 are secured to the casing 5, as at 10, and rest on shafts 7, as indicated in Fig. 2, to yieldingly support the de vice and insure contact ot' all oi' the driving wheels 6 Ion uneven ioor surfaces. .annular -cushions 11, preferably of soft rubber, are provided in said bearings 8 on the shafts 7 to prevent noise in such bearings. Said driving Wheels' are provided with tires 6 of rubber or other suitable substance, to.

increase their -tractive power. Situated through the lower central portion I,ot' said casing, having its axis in parallel relation with said shafts 7, is a rotative brush 13 mounted on a shaft 12 which is journaled on points 14 carried on the free endsu of resilient supports 15. Said supports 15 are secured to the casing 5 by means of screws or bolts, as at 16. By liexing the members 15, as indotted lines 15 in Fig. l, the rotative sweeping brush 13 will be released and i intake ducts 31.

easily takenout'tor cleaning..v Mounted on the end portions of t-he shaft l2 are driving pulleys 17 arranged to be rictionally actuated bythe driving wheels '6.

, Dirt collecting bottoms 18 .arepivoteth as at 19 bymeans of their upturned edges 18', to the Casing to swing downwardly to allow for cleaning the sweeper, and are nominally maintained in closed position by means of coiled'wire springs 20, which are connectedwith the casing 5 and plunger 21 and link 25, andmanually opened by means of forcing a plunger F21 downwardly. Said plunger 2l is pivotally connected with onel oi the upturned edges of said bot-toms 1S, as at 22, and' operatively connected to one of the upturned edges ot the other of. said bottoms by means oil levers and 24 and connecting link 25,- as at 26., ,i

Formed on one end portion ot the casing 5 is a dirt receiving chamber 27m communi cation with an air passage Q8 which is formed between the casing 5 and a base portion 29. Mounted upon said base in) are a plurality of exhausting bellows connected with said air passage Q8 by means ot Said bellows are composed of stationary sides 32, oscillative tops 323 and yielding connecting coverings 3i of a suitable material, such as leather, and provided with the intake' ducts 3l andexhaust ducts 3G. The intake ducts 3l are provided with valves 35 and the exhaust ducts are provided with valves 3T. Said valves 35 and 37 are alike in form and operation v`and consist oi yielding material, such as leather` drawn taut over said ducts by means ofy helical springs 3S. Guides 39 are provided to assist.- in maintaining suchv valves in position. l/Vhen taking air into the bellows, the valves 35 will yield upwardly over their ducts, and when exhausting air, the valves 3T will yieldin a iike manner. driving wheels (3 are rigidly secured to their axle 7 and provided with crank pins i0, and

such crank pins are operatively connected with the bellows 30 by means of connecting rods 41 and members 49, asindicated in the drawings, in a manner to exhaust one bel- One pair of the preferably formed sufficiently long to cover .ajfspacegtt least as wide asthat required by the device in" order to allow .it to remove xlike.f.
