HOWELL, OF PHILADELPHIA, PENNSYLVANIA.

COMBINED PNEUMATIC CLEANER AND FORCE-CUP.

Specification of Letters Patent.

Patented Nov. 15, 1910.

Application filed May 17, 1907, Serial No. 374,169. Renewed April 6, 1910. Serial No. 553,867.

To all whom it may concern: v

Be it known that I, LEWIS O. HOWELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Combined Pneumatic Cleaners and Force- Cups, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates especially to devices employed for cleaning the bowls of water closets, bath tubs, sinks washbasins, and the like, and for forcing obstructions from the waste pipes thereof, and has for its object the provision of a combined pneumatic cleaner and force cup, simple in construction, and effective in operation.

To attain the desired end, my invention' consists in certain novel and useful combinations or arrangements of arts, and peculiarities of construction and operation, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawing, Figure 1 is a side elevation of a combined pneumatic cleaner and force cup embodying myinvention. Fig. 2 is an axial, sectional view thereof at line a-a of Fig. 1.

Similar numerals of reference, wherever they occur, indicate corresponding parts in both figures.

The body 1 of the device is hollow, and made of compressible material, preferably rubber. The wall of this body is made sufiiciently thick to give it some rigidity. The exterior of the wall of the body is provided with two sets or series of circumferential corrugations, those of one set, 2, facing in one direction, and the other set, 3, facing in the opposite direction. From this construction of the corrugations, and their relative arrangement, the device, in use, is ca ble of reaching and thoroughly cleansing beneath the flushing rim of a closet bowl, as-

tion, what I claim as new therein,

The outer face of the body 1 is made concave, as at 4, particularly illustrated in Fig. 2 of the drawing. 5 is a washer held to a manipulating handle 6 by a doublepointed screw 7 The edge of the body 1 is secured in place between the washer 5 and the handle 6 by means of a washer 8 having an annular rib 9 arranged to enter the material of the body 1, the inner edge of the body extending into a recess 10 of the Washer 8, thus effectually preventing any pulling away of the body from the handle when the parts are in place. The washer 8 is shown as made separate from the handle, but it. may be made integral therewith, if desired, without departing from the spirit of my invention.

In use, the corrugations 2 and 3 are employed for cleansing the surface of a closet bowl, wash bowl, bath tub, etc., and when it is desired to force any obstruction from the waste pipe, the concave portion 4 of the implement is placed over the outlet, and downward pressure applied to the body 1 in axial line with the handle, forcing such obstruction down the waste pipe.

Having now fully described my invenand desire to secure by Letters Patent, isi
