To all whom it may concern..-

Be it known that we, SAWYER D. CLARK and CHARLES F. BARTELTJ, citizens of the United States, residing at Boulder, county of Boulder, and State of Colorado, have invented certain new and. useful Improvements in Vacuum-Producing Devices; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same, panying drawings, and to the letters and figures of reference marked thereon, which orm a part of this specification.

, Our invention relates to improvements in vacuum producing devices, our object being to provide a construction adapted to be connected with a faucet through which water is drawn for household purposes, the ordinary system pressure only being employed.

Our improved device consists of a pipe connected with the faucet and extending downwardly a suitable distance, its lower extremity being closed and having openings above the bottom of the closure to allow the water to escape. In our improved construe: tion a hood or shield is applied to the discharge pipe and adapted to surround the portion of the pipe containing the openings, whereby the. water is prevented from spreading over a large area] This hoodconfines the water and causes it to pass downwardly into the sink, or other apparatus through which it may make its escape to the sewer. Connected with this discharge pipe is a conduit leading to the vacuum cleaner nozzle which engages the article from which the dirt or dust is to be removed, The upper extremity of the dischar e pipe, as shown in the drawing, is provide with a removable nozzle which extends downwardly adjacent the opening with which the cleaner conduit is connecte Havin briefly outlined our improved constructlon, we will proceed to describe the same in detail, reference being made to the trating accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a view illusour improved apparatus shown in condition for use. Fig. 2 is a sectional view of the shown on a'largerscale. M

The same reference characters indicate'the same parts in all the views.

This nozzle reference being bad to the'accom-v discharge pipe and its connections shield 19, will be guided downward ..,sin'k 23provided with a plpe leadmg to Let the numeral 5 desi nate a fixture faucet may engage the upper extremity 8 of the e ector nozzle 9 which protrudes downwardly into the member 10 of the part 9 is threaded into the upper extremity of the pipe member 10, adjacent the junction of the member 12 with the -member 10. Connected with the part 12 is the flexible conduit 13 ,whose opposite 'ex-.

' The lower extremity of the fixture 5 has a threaded connection, as shown at 15, with the upper extremity of the discharge pipe 16, to whose lower extremity is applied a sort of cup 17 which is threaded on the pipe extremity, as shown at 18. The lower part of this cup is closed, while its upper portion adjacent the end of the discharge pipe 16, is open to permit the escape of the water after filling the cup 17.

It is evident that a great variety is connected with the cleaner nozof specific constructions may be employed in carrying out our im rovement. The construction illustrated in the drawing, however, has provensatisfactory in actual use. Applied to the discharge pipe 16 and surrounding the apertured portion of the. cup 17 is a shield 19 which has the shape of an inverted cup, its upper extremity having a collar 20 which fits closely to the exterior of the pipe 16 and is held in thumb bolt or screw 21. This shield is vertically adjustable on the pipe 16, since the collar is slidable on said pipe and may be locked by the set bolt 21 in any position of adjustment.

When the device ,is in use, the faucet-is opened, whereby the water is allowed to enter the. member 10 of the fixture 5 and pass downwardly intothe cup 17 which rapidly fills, the water then escaping through the openings in the upper part ofthe cup. It is evident that in the absence of a shield or housing, thewater would be discharged in all directions, through the openings 22. With the shield in place, however, the Water issuing from the openings 22 striking against the walls of the inverted cup y into a -,shaped I place thereon by a necessary suction pull for cleaning purposes.

This is apparently due to the fact that the water backs up in thecup 17, and in combination with the tually seals the lower extremity of the discharge pipe l 6, or causes the water to escape therefrom with suflicient force, to prevent the entrance 'ofair to break the suction. The

Having thus described our invention what we claim is:

As an article of manufacture for domestic a vacuum producing device adapted to be attached to a water spigot and to receive water under pressure, said device comprising an ejector having a discharge pipe whose upper end is adapted to be connected with the spigot, and has a branch pipe for connection with an air tube, and whose lower end is equipped with an enlarged closure which curves outwardly from the pipe, the upper portion of the closure being perforated for the escape of water discharged from the pipe thereinto, and the dome haped hood or shield open to the atmosphere at the water, the hood being applied to the pipe and surrounding the closure in such proximity thereto that the water issuing from,

the'perforations of the closure is controlled. so as to produce a suction efl'ect, in the space between the hood and closure substantially as described.
