CARL R. GREEN; DAYTON, OHIO, ASSIGNOR TO THE NATIONAL VACUUM CLEANING COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO.

To all whom it may concern:

snramron mnx non vacuum CLEANING SYSTEMS.

Be it known that I, CARL R. GREEN, a citizen of. the United States, Dayton, in the county of Montgomery and State of'Ohio, have invented certain new and useful Improvements in Separator- Tanks for Vacuum CleaningSystems, of

which the following is a specification.

My invention relates to improvements in vacuum cleaning apparatus and particularly to receiver or separator tanks therefor.

The object of the invention is to greatly simplify the construction as well as the -me'ans and mode of operation of such devices whereby they will not only be cheapened in construction, but will be more eflicient in operation and unlikely to get out of repair. v

With the above primary andvother incidental objects in View as will appear from the specification, the invention consists of the means, mechanism, construction, and mode of operation or their equivalents hereinafter described, and set forth in the claims.

In the drawings Figure l is a vertical sectional view of the assembled tank. Fig. 2 is a transverse'sectional view on line w-m of Fig. 1. Fig. 3 is a bottom planview -of the tank or separator, and Fig. 4 is a somewhat diagrammatic view showing'the relation of the separator tank to the other parts of the cleaning. apparatus. 1

Like parts are indicated by similar characters of reference throughout the several views. 6

The purpose. of the device is to form a receiver for the dirt and dust taken up in the cleaning operation, and to separate the] dust from the current of air in its passage through the tank. l

The tank proper comprises two members an upper portion 1 and a lower portion 2 provided respectively with-peripheral {flanges nected. The lower portion 2 'is preferably formed slightl conical as shown, and

"is provided with a c osure 5. An inlet nozzle 6 is located in the lower portion 2 which nozzle is connected with the cleanin device or hand piece 7, see Fig. 4-. An 0 .take 8- leads from the upper portion 1 of the tank.

; Secured within the tank and intermediate the inlet 6 and outlet {8 is an'inverted sack 9 of fabric 'orother porous material, through which .the air must pass in'its course from residing at ortions are con-' Specification of Ile tters Patent. 7 Patented Feb, 21., 1911, Application filed February 8, 1908.

the intake 6 to the outlet 8. The sack 9 1 serves to filter the air, the dust particles being deposited on the interiorof the sack, the air passing through the ,porouswalls and out through the outlet 8 to the pump 10. The sack 9 is made with a laterally projecting brim 11 of fabric, somewhat in the form of a peripheral flange about the mouth thereof. The diameter of the sack 9 is somwhat less than that of the tank. The sack is secured in position by the engagement of the lateral brim 11 thereof between the flanges 3 and 4. 1

To maintain the sack 9 central in the tank and to prevent the walls thereof from comthe sack is in an inflated condition, and thus reducing the filtering surface of the sack, a metal collar 12 is provided the interior diaineter of which is less than thatof the tank and substantially equal to that of the sack. The inner edge of the collar is provided with a head 13 ,upon which the sack bears, thus obviating danger of chafing or undue wear upon the sack material. The collar 12 rests on the brimll of the sack 9 and between the flanges and 4; Packing 14 is also inserted between the flanges, and the sack, the collar 12 and the packing 14 all clamped in position by bolts or rivets 15 connecting the flanges 3 and 4i 7 Supported on arms 16 in the ortion 2 of the tank, and in direct line with the discharge of the intake 6 is a deflector 17 conical in form and, adapted to arrest and distribute the inrushing current of air, permitting the particles of dirt carried thereby to settle in the bottom of the portion 2.

It has been found in practice that without the use of the deflector 17 the inrushing current of dirt laden air will continually agitate the dirt deposited in the bottom of the tank and keep the dirt in violent motion within the tank, and an undue amount of the larger particles willbe deposited on' the interior of the sack 9, thus clogging the filter. The deflector 17 being in direct line of the incoming air current will receive the impact thereof and arrest the current of air, and the dirt carried thereby will settle into the bottom of the tank where it will be protected by the deflector 17. V

In order that the deposit of dirt may be readily removed from thetank, the closure 5 is removable and comprises a plate, secured in position by dogs 18 pivoted to ears 19 on said closure plate 5 and engaging a flange 20 about the mouth of the tank. The dogs 18 each have'an arm 21 engaging over the flange 20 and an arm 22 having therein an adjusting screw 23 bearing on the closure plate 5, whereby the operation of the screws 23 will oscillate the dogs 18 on their pivots and cause the arms 21 to bear on'the flange 20, drawing the plate 5 into close contact with the mouth of the tank. The dogs 18 each have twoinward projecting arms 21, 22. The arm 21 projects over the upper side of the cover plate to a limited extent, and when in place over the flange. The lower arm 22 projects under the cover plate. In

other words, each dog 18 has on its inner side a recess within which the cover plateand flange project, or the dogs might be said to be substantially 7 shaped, one arm of the 7 being short and engaging on the upper side of the flange 20, the long arm extending below the cover plate. The screws 23 are screwthreaded in the arm 22 and bear upon the cover plate. By operatin the screws 23 the long arm of the dog is orced away from the cover plate, but the dog turning on the pivotal connection with the cars 19 and causing the short arm 21 to bear strongly on the flange 20 will draw the cover plate more closely to the receptacle by a prying movement in which the dog 18 is a lever, the short arm 21 on the flange being the fulcrum, the. screw 23 in the long arm the power and the cover plate engaged through the ears 19 the work.

Attached to the interior of the sack 9 is a rod 24 which is suspended from the top thereof when the sack is inflated by the air passing there through, but when. the sack is collapsed the rod 24 will drop down within reach when the closure 5 is removed and may be used to shake the sack 9 to loosen the particles of dust adhering thereto.

The tank is located between the pump 10 and the hand piece. 7, being connected to the pump 10 by the ofl take 8. A conduit 25 connects the hand piece -7 with the intake 6. The pump being operated draws a current of air from the hand piece 7 through the tank to said pump. The current of dirt laden air enters the tank through the inlet 6 and is discharged downward, striking the deflector 17 by which it is arrested, the dirt particles being allowed to settle into the bottom of the tank, while the air with some of the more fine dust particles pass upward within the sack 9, the air passing through the porous walls of said sack, and the dust particles being deposited on the interior thereof. The air passes from the tank through the outlet 8 to the pump. To remove the dirt deposit the closure 5 is removed by loosening the screws 23 when the I dogs 18 may readily be disengaged from the flange 20, permitting the dirt to drop from the tank. The rod 25, which will project through the mouth of the tank when the tank is open may be shaken-to free the filter sack 9 of any dust particles clingin' thereto, and upon the replacement of the closure 5 the device is in condition for further operation. v H

From the above description it will be ap-' parent that there is thus produced a device of the character described, possessing the particular features of advantage before enumerated is susceptible of modification in its form, proportion, detail construction, and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

Having thus described my invention, I claim V 1.
