Description

Patented May 26, 1936 UNITED STATES PATENT oFElcE VACUUM DEVICE Roy A. Watson, Ashland, Ohio Application August 6, 1935, Serial No. 35,002 olaims. (c1. L -255) The invention relates to a vacuum device and more especially to a vacuum rimmed force cup.

The primary object of the invention is the provision of a device of this character, wherein the body of the cup carries a flexible double wall having partitions to maintain these walls separated and for forming the vacuum wells so that the rim of the body will eifect a seal or an air proof contact around a drain opening and in the operation by a pumping action this causes air within the drain pipe to pulsate and aid in the removal of obstructions.

Another object of the invention is the provision of a device of this character, wherein the vacuum within the double wall of the body of the device may be broken so that the device can be removed more readily When about a drain opening.

A further object of the invention is the provision of a device of this character, wherein the vacuum spaces or chambers at the contacting edge of the body serve to hold this edge under vacuum grip to have the body in place while in operation.

A still further object of the invention is the provision of a device of this character, which is simple in construction, safe in the working thereof, thoroughly reliable and efficient in its operation enabling the dispensing of stoppage of drain pipes, strong, durable, and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a vertical sectional view through a device constructed in accordance with the invention.

Figure 2 is a bottom plan view thereof.

Figure 3 is a fragmentary sectional view on the line 3 3 of Figure 2 looking in the direction of the arrows.

Figure 4 is a sectional view on the line 4-4 of Figure 2.

Figure 5 is a sectional View on the line 5-5 of Figure 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the device comprises a substantially bell-shaped body I0 and is similar or resembles the usual type of plunger affording a suction cup adapted to be placed over the opening of a drain pipe (not shown) and the contacting edge of this body I0 has formed therein vacuum spaces or recesses I I, these separated by cross partitions or webs I2 which are slightly less than the depth of the spaces or recesses II so that communications I3 will be had between the spaces or recesses II throughout the annular series thereof as provided in the thickened contacting edge I4 of the body I0.

This body I0 at its top is formed with a socketed extension or coupling nipple I5 having threaded engagement as at I6 with a handle, a portion thereof being indicated at I1 for plunger action of the device.

It is, of course, understood that the body I0 is possessed of inherent resiliency so that this body will flex removed from the contacting edge M and in the use of the device by pumping action obstructions within a drain pipe will be relieved.

The vacuum spaces or recesses II assure a seal tight grip by the edge I4 around a drain opening .and the advantage being that the body I0 will be held in place while operating the device.

Provided in the body I0 is an air vent I8 which leads to one of the spaces or recesses II and opens upwardly through the extension or nipple I5 so that when the vent is open the vacuum will be broken in the spaces or recesses I I. 'This upper end of the vent I8 has fitted therein a removable stopper or plug I9 which, when in place, closes such vent for the vacuum action of the spaces or recesses II in the use of the device.

What is claimed is:

1. A drain cleaning device comprising an elastic hollow bell-shaped body having an open end and provided with vacuum recesses in the edge of said open end and intercommunicating with each other, the said body having a vent opening into one of the recesses and to the atmosphere, and a sealing means for said vent to shut olf communication thereof with the atmosphere.

2. A drain cleaning device comprising an elastic hollow bell-shaped body having an open end and provided with vacuum recesses in the edge of said open end and intercommunicating with each other, the said body having a vent opening into one of the recesses and to the atmosphere, a sealing means for said vent to shut olf communication thereof with the atmosphere and operation means connected with said body.
