HORACE H. TAJYLOR AND LEONARD MGBEBRY, OF OKLND, CALIFORNIA.
VACUUM-CLEANER.
Specification of Letters Patent.
I Patented dan. 9, 1917.
Application filed February 1, 1916. Serial No. 75,494.
To all Iwhom t may concern Be it known that we, HORACE H. TAYLOR and LEONARD A. MOBERRY, citizens of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Vacuum-Cleaners, of which the following um cleaner having a brush which willrotate 4.in afnniform directionwhether the vacuum cleaner be propelled forward or backward. In the accompanying drawing, Figure 1 is a side view of the machine; Fig. 2 is an enlarged longitudinal sectional view on the line 2-2 of Fig. 3; Fig. 3 is a plan view on the line 4-4 of Fig. 3 thereof; Fig. 4 is a detail sectional view of a conduit leading from the lower bellows chamber.
Referring to the drawing, 1, 2 'indicate upper and lower stationary bellows boards secured at their front ends to a metallic head block 3, having a central member 4, which is pivotallyattached to the front end of a central vibrating board 5, connected at its' edges by leather 6 to the edges ofthe stationary bellows boards 1, 2. Said upper and lower bellows boards are connected to a metallic frame 7, from which extend trunnions toy for the front wheels 8, and are also connected to metallic frames 9, from which extend shafts for the rear wheel 11. Secured to the lower bellows board and surrounding Isaid wheels is a metal fender 12.
Extending from the rear corners of the vibrating bellows board 5 are lugs 13, which are pivoted to slotted arms 14 of a bell crank' lever 16, pivoted on pins 17 extending from said metallic frames 9, s aid bell crank lever extending over said upper stationary bellows board 1, and formed at its middle portion with a channel or groove 18. In said groove can reciprocate a crank pin 19, having a rounded head 21 slidable in the groove, and depending from and secured to a' balance wheel 22, formed integral with ashaft 23, and secured by a collar 24 in a bearing 25, supported by a metal yoke 26, secured, as shown at 27, to the upper bellows board`1. Secured to the upper end of said shaft by a hole 28 therethrough is the lower end of a flexible shaft 29, the upper end of which is connected to alrigid shaft 30, havingA its bearings in a tube 31, which tube has a pivoted yokelike extension V32 which canbe clamped at any point by means of a clamp-` ing nut 33 on a screw 34 extending through an arcuate slot 36 in an extension 37 of the yoke 26. The u-pper end of said rigid shaft 30 carries a bevel pinion 38 which meshes with a bevel gear39mounted upon an extension 41 of-the tube, the shaft of said bevel gear carrying a crank arm 42 by which it can be turned. Said extension 41 carries a handle 43 by which the whole apparatus can be propelled.
By turning the crank armV 42 the shaft 23 can`be rotated, thus causing the crank pin '19 to revolve about said shaft and produclng an oscillatory motion of the bell crank lever 16, thereby also producing an oscillatory motion of the bellows board `5 to and from the bellows yboards `1 and 2 alternately.
Thereby dust-laden air is drawn from chambers 44 Apast clack valves 46, 47, the upper clack valve 46 being closed by a spring 48, and into chambers 49, 51, which are alternately suction and pressure chambers. The
dust-laden air in said chambers, when thev chambers are contracted, is expelled through valves 52 and 53 into conduits 54, 56, the lower chamber communicating withA said valve by a conduit 57, shown in detail in Fig. 4, passing through the upper chamber. The conduits 54 and 56 lead to a central conduit 58, which is adapted to be connected with a dust bag, not shown.
The lower side of the metal frame 7 is concave, as shown at 59, to form a chamber for a rotary brush 61, the shaft 62 of said brush being secured to pulleys 63 around which pass belts 64 and 66 one of which is crossed, said belts also passing around pulleys 67, 68 loose on extending hubs 60 of the front wheels. Said pulleys 6'?, 68 carry pivoted. dogs 69, which are pressed by springs 71 into engagement with the teeth of ratchet wheels 72 tight on said hubs 60. Said ratchet teeth and dogs point im opposite directions, so that, Whether the apparatus is being propelled forward or backward, the shaft of the brush always rotates in the same direction. The brush chamber is closed at the ends by end plates 73, and the front ends of the fenderl?. are secured, as shown at 74, to said end plates.
The chambers 4A communicate with a common conduit 76, which extends around said brush chamber to the front thereof and `communicates with a cylindrical` valve of registry with the conduit 8l and the wide.
Located centrally in the upper portion of the frame 7 is a short conduit 84 communieating with the conduit 76, to which can be connected a tube having at its end a nozzle for the vacuum cleaning of articles above the floor.
We claim In a vacuum cleaner, the combination of a pump, a metal frame secured thereto, having'a concave portion forming' with the surface to be cleaned, a brush chamber, a ro tary brush inl said chamber, said frame also forming a valve seat, a rotary valve in said seat, and conduits in said frame leading to said valve seat from the brush chamber and from a portion of the frame in close proximity tc said surface, said valve being formed with ports adapted to alternately register respectively with said conduits, and means whereby said valve can be turned in its seat, said frameforming a conduit from the valve seat to the pump.
In testimony whereof we have hereunto set our hands in the presence of two subscrlblng witnesses.
