Application filed March23, 1910. Serial No. 551,029.

To all whom it may concern:

Be it known that I, LEAL'L. MONTGOMERY, a citizen of the United States, and a resident of Superior, in the county of Douglas and State of WVisconsin, have invented a new and Improved Vacuum-Pump and Cleaning 1 Apparatus, of which the following is a full,

clear, and exact description.

This invention relates to a new and im- 3roved system for obtaining a vacuum by hydraulic pressure, whereby cleaning by vacuum may be accomplished, and which maybe reversed to form, to a certain extent, a hydraulic air-compressing pump.

An object of this invention is to provide a device which will be simple in construction, inexpensive to ,manufacture, strong, durable, and automatic in its operation.

. A further object of this invention is to provide a system in which hydraulic means creates a vacuum or pressure, with means for automatically controlling said hydraulic means by the vacuum or pressure created.

These and other objects, together with the construction and combination of parts, will be more fully described hereinafter and set forth in the claims.

Reference isto be had to the accompanying drawings,.fo rming a part of this speci fication, in which similar characters of reference indicate corresponding parts in all the figures, and in which Figure 1 is a vertical section showing a fragmentary portion of my system in opera tion; Fig. 2 is an enlarged vertical section of thevacuum former; Fig. 3 is a horizontal sectionon the line 33 ofFig. 2; Fig. 4 is an 'enlarged fragmentary sectional elevation ,of the valve control; and Fig. 5 is an enlarged. detail section of the automatic valve for preventing the water from entering the distributing system in case of derangement of..the mechanism.

Referring more particularly to the separate parts of the device, 1 indicates a vacuum former, which is supplied through a nozzle 2 with water under pressure, whichis supplied by means of a pipe t, connected to a pump or'any other suitable source of'water under'a head. :The vacuum former 1, which, as will be seen later, may also be termed a dust collector and a pressure former, consists of acasing 5 formed with a vacuum chamber 6 at the upper end, and provided with "a plurality of telescoping pipes or nozzles 7, 8 and 9. It will be noted that between the pipes 7'and 8 and 8 and 9, there are provided annular chambers 10'and 11, 1n which a vacuum is created by the downward rush of air through the nozzles, thereby tending to regulate the operation of the device. Connected to the vacuum chamber 6, there is provided a pipe 12, which in turn is connected to a distributing system represented by apipe 13. This distributing system is provided with a plurality of valve- I controlled auxiliary pipes 1 1, to which may be attached suitable cleaning devices, such as vacuum cleaners or pressure clusters. The flow of fluid between the pipe 12 and the system 13, is controlled by means of a valve 15.

In order that the water in the vacuum former 1 may not back up into the system represented by the pipe 13, there is provided an automatic valve 16, the exact structure of which will be more readily seen by referenee to Fig. 5. It will be. seen here that the valve 16 consists of a casing 17, having upwardly-extending flanges 18 spaced apart from each other, so as to form a support for a ball valve 19, in such a manner that it will permit the flow of fluid down through thepipe 12. The upper end of the casing 17 is provided with a resilient packing 20,

against which the ball 19 is adapted to impinge when raised by a back. pressure in the pipe 12, so as to prevent the flow of fluid in an upward direction and thus prevent the fluid from backing 11 into the system 13. The fluid which is uti ized in creating a pressure or "vacuum in the former 1, flows out together with the air drawn thereby through pipes 21 and 22 intoa tank 23. The flow of fluid through the pipe 22 is controlled by means of a valve 2%. The pipe 21 is also connected by means of a stub pipev 25, to a tank 26, which is preferably superposed on the tank 23 andconnected thereto by means.

of a pipe 27, which" extends in close juxtaposition to the bottom of the tank 23. The flow of fluid through the stub pipe 25 is controlled by a valve 28. .In order that the pressure in the tank 26 may not act back on the former 1, there is provided an automatic check. valve 29, which is adapted to close when the pressure in the tank 26 exceeds the pressure .in the former 1.

It is to be noted by reference to Fig. 1,

that the'system pipe 13 is provided with a break indicated at 30, located in the tank 26 adjacent the top thereof, so that when a vacuum is created by the former 1, the ef-.

' feet thereof will be felt in. the tank 26. The

or sleeves 35 and 36.

purpose of having the vacuum evident in the tank 26, is to provide means for controlling the supply of water to the former 1 and cut oil thissupply when the vacuum being created is no-longer used. For this purpose, there is provided in the pipe 4, a valve 31, which is connected in a manner to be described, to a float 32 located 1n the tank 26.

The specific manner of connecting the valve 31 to the float 32, is more clearly lllnstrated in Fig. 4. Here it will be seen that the valve 31 isprovided with a lever 33, which is pivotally connected in any wellkn own manner to a casing 34. The interior of the casin 34 is screwthreaded at each end, to provlde a suitable means for securing corresponding screw-threaded thimbles Extending through the thimbles 35 and 36, there is provided a rod 37, which projects through the bottom of the casing-34 and through asuitable pack: ing joint 38, into the interior of the tank 26, where it is connected to the float 3.2 in such a manner as to provide a limited relative motion thereto, as by means of the slotany well-known manner, spring-pressed and-pin connection indicated at' 39. The rod 37 is provided intermediate its ends with a trip 40, in thenature of a beveled collar secured to the rod in any well-known manner. This trip forms a convenient abutting. member for springs41 and 42 arranged on opposite sides thereof and abutting at their opposite ends against the thi nbles 35 and 36, respectively. It will be seen that the tension on the springs 41 and 42 can be regulated by, regulating the position of the thinnbles '35 and 36 with 'respect 'to the casing 34, so that the motion of the rod 37 in either direction can be controlled to respond to a given force in either direction.

Arranged alongside of the casing 34 and supportedv in any suitable manner as by being secured to the tank 26, there is provided a frame 43, which. slidingly. supports in dogs 44 and 45 which are adapted to alternately en age, respectively; openings 46 and 47 in t e casing 34. WVhen-the dogs 44 and 45 engage the openings 46 and 47, respectively, they look the casing 34in positions corresponding, respectively, to the open and closed positions of the valve 31. The dog's 44 and 45'project into'the interior of the casing 34 in such posit-ion that they will be readily engaged by the trip 40 during its motion, soas to disengage them and permit the vertical movement of the casing 34, and thuspermit themanipulation of the valve 31. Inasmuch as the trip 40 can only move a suflicient distance torele'ase the dogs 44 and 45 when its operating means has overcome the tension of the springs 41 and- 42, any slight variation in the pressure or "acuum in the tank 26,'will not actuate the float 32 a suflicientamount to operate the valve 31', so that this valve will not be constantly opened and shut to respond to slight irregularities. v

It will be noted by reference to Fig. 1, that there is provided an overflow pipe 48, connected to the upper end of the tank23, Which'is -adapted to carry ofl' the water saturated with dust and dirt from theyaeuum cleaner into a sewer pipe indicated. at 49.

When it is desired to use the system as a pressure pump, it is advisable to have a direct inlet of air, to the former 1, which is represented by a pipe 50, the flow of fluid through whi'ch'is controlled by a valve 51.

v The operation of the device will be readily and thus in the tank 26 and the system pipe suction in the pipe 12 i 13. Vacuumcleaners -or other devices in other rooms may be attached to the'connections 14 and utilized by opening the valves therein. The dirt and air entering the, vacuum: cleaner travel down through the pipe 13 into the pipe 12 and thus into thev former 1, from whence' they flow with the water into the tank 23.

els off through the sewer pipe "49'. If, for

any reason, water should be fed too fast to the former 1,any tendency of this water to back up in the system pipe 13,- will be checked by the automatic valve 16, which will automatically drop when this abnormal condition has passed.- When further use of the vacuum in the system pipe 13 has ceased,jand the valve in the connection 14 is closed, there will be no further necessity for the vacuum, and the excessivevacuum created will withdraw the air from the tank 26, so that the water in the tank 23 will be drawn up into the tank 26. When this water has reached the float 32, if the vaeuum'still continues, the rod 37 will be positivelyforced upwardly against the tension of the spring v41,

When the tank 23 becomes full, the dirt-saturated water travso. that the trip 40 will raise the dog 44, per-,

mitting the casing 34 to be moved upwardly by the float 32, thus Should the vacuumbe used again in the system 33, the vacuum in the tank 26 will be broken, thereby permitting thewater therein to flow back into the tank 23,;thus allowing the weight of the float and to open the valve 31 when the water in. the tank 26 has receded sufliciently to permit the weight of the parts to exert the force neces sary. The springs 41 and 42 will permit slightchanges in vacuum without operating the valve 31, and the tension thereof can be closing the valve 31.

the casing 34, i

varied by "the thimbles and 36. Then zhe.v water fills the tank 26, the check valve 2-9 automatically prevent-s its being drawn )ack into the ormer 1.

When it is desired to use the system as a,

oressure system, the valves 15 and 24 are ilosed and the valves 28 and 51 opened. The III will then be drawn directly through the 1116i? into the former 1, where it is compressed by the h draulic force of the water admitted throug the pipe by the valve .31. Pressure created in the former 1 is accumulated in the tank 26, which acts as a storing tank. Inasmuch as the pipe 13 is provided witlrthe break 30, which is located interiorl of the tank 26, the pressure created in the ormer 1 and stored in the tank 26, can be utilized in the system pipe 13 by connecting to the extensions 14, any suitable devices, such as pneumatic pressure dusters.

There will be a water-seal on the bottom of the pipe 27, so that the pressure accumulated in the tank 26 cannot escape into the sewer pipe.

While I have shown one embodiment of my invention, I do not wish to be limited to the specific details thereof, but desire to be protected in various, changes, alterations and modifications which I may make within the scope of the appended claims.
