Application filed September 22, 1910. Serial No. 583,284.

To all whom it may concern:

Be it known that I, GEORGE WEBSTER, a citizen.- of the United States," residing at Christiana, in the county of Lancaster and State of Pennsylvania, have iii-vented certain new and useful Improvements in Sucvices,

tiondrod'ucing Apparatus, of which the following is a specification.

V This invention comprehends certain new and useful improvements in that class of dethat are known as vacuum or suction clean s, and the invention has for its priof the parts that Ishall hereinafter may object a simple, durable, inexpensive and, efficient device of this character which isoperated by a double action see-saw bellows upon which the operator may stand,

the motion of the body in moving the suction-nozzle back and forth, tending to throw the weight of the operator from one bellows to the other, thereby creating a strong and scription and accompanying drawings, in

which:

I Figure 1 is a perspective view illustrating -my improved suction cleaner, the bellows be- Y ing shown separated from the other parts;

Fig. 2 is a perspective view of the parts combined, the handle and suction nozzle of the device being omitted; Fig. 3 isa longitudinal sectional view of the device, the vacuum chamber being shown partly in section and partly in side elevation; Fig. 4: is a transverse sectional view, the section being taken through the middle of the bellows and showing a portion of the vacuum chamher; and Fig. 5 is a sectional. perspective view illustrating the vacuum chamber and the parts which it contains.

Corresponding and like parts are referred I to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved suction cleaner embodies a bellows A which comprises a base 1 formed of two inclined members 2 merging at the,

middle in a transpersely elongated foot 3,

and a tilting platform 4 which is hingedly connected at its middle to the-middle of the base 1, in any desired way.

5 designates leather or similar bellows ma- 'teri al or substance which is secured in any deslred manner to the marginal edges of the base 1 and platform 4 on opposite sides of the middle thereof, whereby to'produce a double action or duplex bellows which may be operated by one standing'on the platform 4 and tilting the latter after the manner of a see-saw. Preferably, the platform 4 is formed in its upper face with depressions 6 so as to prevent the feet of the operator from slipping. Each side or compartment of the double bellows A islprovided with a. suction valve 7 and a discharge valve 8, the latter being of the spring pressed flap variety, as clearly illustrated in the drawing, and-being securedto the lower 'face of the base and accommodated by the inclined parts thereof. The two suction valves 7 control openings 9' which lead into the bellows compartments, said openings both leading to a common transversely extending bore 10,'in which a tubular spindle 11 is mounted for a turning movement about its longitudinal axis. The spindle 11 is secured to the side wall of a'cylindrical vacuum chamber in the form of a fiat bottom can 12 and extends within the latter, as shown, being formed within the can with any de sired number of orifices 13, so as to permit the air to pass from the can through the spindle and into the bellows, 'and out of the latter to the atmosphere.

A bag 14 is held within the can 12, said hag, being composed of cambric or other suitable cloth arranged to pass air easily therethrough and at the same time catch and retain dust and other particles, and a cylindrical screen 15v is interposed between the bag and the interior wall of the can 12 so as to prevent the air from. pressing the bag against the side of the can, the air being thus permitted to escape all around. The bag ltis formed with a relatively heavy mouth rim 16 which is engaged by the lid 17 of the can so as to hold the bag in place. This lid is provided with a nipple 18 to which the flexiblehose 19 is connected, said hose being secured to one end of the tubular handle QO- hich is provided at its opposite endwit-h a suction nozzle 21 of any desired formation. Obviously, the can 12 may be turned on the spindle 11- as an axis so that it may extend longitudinally of the bellows and economize'space when the apparatus is not desired .for use, the can being turnedupright or at right angles to the bellows in the operation of the device If desired, the can may be held in said-last named position by a pin 22 or the like'extending through an opening formed in the foot 3 and a'corre.-

sponding opening formed in the spindle,

the foregoing description in connec-' tion with the accompanying drawings, the

operation of'my improved suction cleaner.

will be apparenhw In the practical use of the device, the, operator stands ,on the tilting platform 4 and operates thesameafter. the manner of a see-saw, the two parts of the bellows operating alternately and pro-' ducing a regularlystrong suctionpthe 'dustparticles being thereby drawn in through the nozzle 21 and into the can 12, beingcaught by the bag 14, theair passing through the ag and out through the outlet or discharge valves ,8. As before-stetedfhy nioving 'the nozzle baek'and forth, the body of the operatorwill naturally mot sin maxi;

thereby throwing the weight of theoperator from one part of the bellows to theioth'ex" and creating a strong suction and doubh'a action. Having thus described the invention, what is claimed as new is: 1
