'VACUUM-CLEANER.

Specification of Letters Patent.

Application led June 9, 1910. Serial No. 565,964.

' To all whom tmc/ 1.; concern:

Be it known that I, JOHN A. FORNEY, citizen of the United States, residin at Reading, lin the county of Berks and tate of Pennsylvania, have invented -'certain new and useful Improvements in Vacuum-Cleaners, of which the following is a specification.

This invention relates to improvements in vacuum cleaners and the present invention is intended more particularly for domestic use, and, as shown, is intended to be operated by hand.

The device consists of a carriage, capable of being moved along the surface to be. cleaned, the movement of which creates the power to operate the suction pump.

The invention consists of a pump having a pair of suction pistons connected by crank arms vto the wheels of the device in such manner that when the machine is moved along the surface to be cleaned, the pistons are operated. Each piston is connected to one of the wheels through the medium of piston rods, cross-heads and driving Aarms and they are so connected that the pistons move toward and away from each other at every revolution of the wheels.

A further object is to utilize the operating handle for the triple purpose of a handle, guides for the cross-heads andA an outlet or exhaust from the pump.

The invention is more fully described in the following specification and clearly illustrated in the accompanying drawing, in which:-

Figure 1" is a front elevation of my machine. Fig. 2 is a side -elevation thereof. Fig. 3 is acentral sectional view through line X-X of Fig. 1. Fig. 4 is a detail view of one of the suction pistons.

The numeral 1 designates the pump, which is shown as a cylindrical casing with a dust receptacle 2 secured to its lower end and having a dust strainer 3 interposed between the dust receptacle and the pump. This joint is also provided with a rubber washer 4 to insure an air tight joint.

The numerals 5 and 6 designate the upper and lower suction pistons, respectively. These pistons each are provided with a piston rod and they move in opposite directions. The rod 9, connected to piston 6 is solid and passes through the upper piston 5 and its hollow rod 8 and the upper end of each of these iodsis connected to a crosshead 10 which is in turn connected to a driving rod 11.

The casing is suitably mounted on a pair of wheels 12 and the rods 11 are connected, each to one of these wheels and at diametrically opposite points, so that the crosscross-heads and in addition thereto, it alsov serves as an outlet or exhaust from the pump. Its extremity 14 may be provided with a hose connection 15 forl a blower if desired. 1

' The dust receptacle 2 is provided with an inlet tube 16 to which any suitable nozzle 17 may be secured. A. detlector 18 is provided, inside the receptacle and over the tube opening, to deflect the current of air and dust. The dust screen 3 is provided with a central disk19 of rubber, leather lor like material, and the under side of the lower Ipiston 6 is provided with a central lug 20, so that when the piston reaches its lowermost point, the lug will strike the disk and this tapping at each stroke will tend to keep the screen clean.

It is evident that with my improved machine, the movement ofthe device on its wheels along the floor will, through the driving rods, cross-heads and piston rods, move the pistons in opposite directions, and as each piston is provided with valves which open upwardly, the suction into and exhaust `Patented Nov. 8, 1910. i
