Application filed June 6, 1912. Serial No. 791,932.

citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful.

Vacuum-Cleane'n'of which the following is a s ecificntion.

K t is the object of this invention to pro vide 5- light, ortable, hand-operated vacuum. cleaner w. ich is simple of construction,

' is not laborious to operate, and is readily cleanable. To this end I provide a hollow rod which carries a suction mouth-piece at one end and isprovided with a handle at the other, and mount on this rod a reciprocable cylinder. The ends of the cylinder are provided with removable caps which carry dust strainers and are provided with exhaustvalves, airbein admi ted 'to the intei'ior of the cylinder, Am the mouth-piece through the hollow rod by inlet valves mounted on apiston which is carried by the rodwithin. the cylinder and divides the space within the latter into, two pneumatically separate parts.

In the accompanyin drawing, which illustrates my invention, ignre 1 is a artly sectional side elevation ofa. vacuum c eaner involving my invention; Fig. 2 is an enlax-god. fragmentary section through the lower end of the cylinder and associated parts; Fig. 3 is an end view of the piston between the two sections witbin thc cylinder; Fig. 4 is a sectional view of said piston, being taken on the line 14 of Fig. 5; Fig. 5

- is a section ontheline 55 of Fi 4; and

Fig. 6 is an end view of the cylin er showin the cap fastening arrangement.

%he rod or tube 10 is provided at its lower end with a suction mouth-piece 11 of: any suitable type and is curved at its upper end to form a handle 12. At a convenient point in its length, the opening through the tube 10 is closed by a barrier 13, on the mouthpiece side of which the tube is provided with a. lateral opening 14 which opens into the space inclosed between the two end disks 15 and the wall 16 of 'a hollow piston fixed on thetube 10. The space within the hollow piston may take any shape within the limits of the area of the disks 15, but is conveniently of the shape shown in Fig. 4, the edges of the disks 15 opposite the wall 16 being spaced apart by an arc-shaped wall 17. Each disk 15 is provided with ahole com- ;hole being closed by a valve 19 which allows air to pass only outward from said-space.

f16 and'17 to form flanges, loosely fitting between which is a packing21 which fits .closely a ainst theinside of a cylinder 22 reciproca ble along the rod or tube 10 by an operating handle 23. A removable cap 24 der and caps being provided with interlocking flange. fingers 25 and 26 for holding the neck 27 projecting inwardly into the cylinder, and on each neck is clamped, by clamp termediate enlarged portion 27 between the a ring 10, of rubber or other yielding ma-. terial, which holds the fabric of the strainer inder 22 when the cap is in place. The smaller ends of these strainers fit closely around the tube 10, conveniently being held tight by draw strings 30, but permitting relative sliding between the tube 10 and the small end of the strainer. The small ends of the strainers 29 are yieldingly held away fiom the corresponding caps 24 by light springs 31, which thus keep the bag distween the cylinder and tube. Each cap 24 is provided with a cylindrical opening 32 somewhat larger than is the tube 10,

is a felt washer 33, which fits closely around the tube 10 and loosely between the cap 2 1 'and a bridge 34: carried by the cap. The bridges 34 are provided with. packings 35 which fit around the tube 10 to guide the movements of the cylinder.

As the cylinder 22 is reciprocated on the tube 10 by the handle 23, air is drawn through the mouth-piece 11 and the tube 10 through that valve 19 which opens into the at time is becoming larger, the air on the other side of said disk at the same time .being. forced through the corresponding strainer :29 and out through the opening 32, from which at that time the cooperating washer 33 is separated. The acking 21 fits closely against the inside of t e cylinder 22 Y The disks 15 project slightly beyond the walls fits in each end of the cylinder 22, the cylinrings 28, the larger end of a conical fabric strainer or filter 29. The neck 2'? has an intended during relative reciprocation be- =municating with the aforesaid space, said' caps in place. Each cap is provided with a rings 28, and on this portion 27' is mounted tightly against the inner surface of the cyland covering this opening to form a; valve space on that side of the disk 15 which at t and against that disk 15 which is toward the I receding cylindenend, and-serves to prevent communication between the spaces on the two sides of the piston. The strainer 29 removes the dust t'rom the air. The device thus operates as a double acting pump as the cylinder 22 is moved heel: and forth along the tube 10, or as the tube 10 is moved back and forth through the cylinder, the latter movement at the same time moving the mouth-piece 11 along the surfa'ce to be The air strainer 29 rermvesthe.
