Feb. 16, 1932. I E. ROBINSON 4 PIPE! CLEANING TOOL Fi led May 14, 1931 3nventor Patented Feb. 16, 1932 UNITED STATES Louis- E. nonrnson, or COUNCIL iaLUEFs; IOWA V PIPE CLEANING 'roon' Application filed May 14,

This invention relates to a tool for cleaning pipes, and more specifically soil pipes leading from water closets, these last named pipes having curved forms which may occasionally become obstructed. I

The object of the invention is to provide a tool which will be convenient in use will be efiective in removing obstructions from soil pipes, and will be of such simple construction that it will not be expensive in manufacture.

The invention consists of the new and useful construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the accompanying drawings, it being understood that changes may be made in form, size, proportion of parts and minor details, said changes being within the scope of the invention as claimed.

In the drawings, Fig. 1 is a side view partly in section showing the use of the tool applied to a soil pipe. 7

Fig. 2 is a broken away side view of the tool, with the hose pipe omitted. Fig. 3 is a similar view to that shown in Fig. 2, the hose pipe being in position. Fig. 4: is a view in longitudinal section showing the terminal part of the tool.

Referring now to the drawings for a more particular description, the invention consists of a coiled spring 5 which may be constructed of strong wire having a suitable degree of elasticity so that it will readily yield upon pressure and will assume its original spiral form when released from pressure. In outline it is of tapered form, said outline being convergent toward its distal end. Numeral 6 indicates a handle for the tool.

Numeral 7 indicates a section of hose which is disposed in the spiral spring, the intake for the hose being indicated at 8 and its discharge port being indicated at '9, said discharge port being a part of a valve-housing 10, the hinge valve controlling sa1d discharge port being indicated at 11.

The hose is provided with a threaded collar 12 adapted to be mounted in the interiorly threaded end-portion 13 of the valve-housing. At 14 is indicated a detent-ring provided with a pair of opposed prongs 15. The

valveisprovidedwith a butter-plate 16 which 1931. Serial na'saassi.

projects outwardly through the port 9 from thevalve e In Fig. 4 of the drawings the hose is shown in detached relation with the valveehousing, but it will be understood that the parts may be rotated fora mounting of the threaded collar 12 in the valve-housin g. i i It will beseen that since the prongs 15 projectoutwardly/of the coiled spring 5 the valve-housing will not become "detached. from thefspring during use. 7 For operation, the spiral spring shown in Figs. '1 and 2 may be used without using the hose if desired, but in some instances the hose and its valve are of great advantage for removing obstructions, water under pressure being usedand a connection beingmade with the intake 8of'the hose from any suitable source or" supply, pressure of water in the hose normally causing closure of the valve 11 s r In operation, when the parts consist sim-' ply of the spiral-spring shown in Fi s. 1 and 2: for removing an obstruction,the handle 6" is'used 'for rotating the tool, and since the tool is elastic it may be moved through the curved parts of a pipe, and when the distal end'of the tool engages an obstruction 00, said obstruction will generally become caught between the coils, and the tool may then be drawn outwardly for removal.

It will be seen thatthe valve-housing 10 may be adjusted longitudinally of the spiral spring 5 so that the bufier-member 16 may be disposed closely adjacent to the terminal hook 17 of the spiral spring 5, or in advance of said hook.

The valve may be readily attached .or detached from the hose. After the ring 14 has I been placed a suitable distance from the hook 17 between a pair of adjacently disposed coils of the spring the valve-housing is inserted and, by rotating these parts, the valvehousing will become threaded in the detentring.

Since the hose is flexible the tool may be rotated in the manner already mentioned, and an obstruction may be engaged by the hook 17 for removal. In some instances however, the obstruction may be of such consistency that the spiral spring will not move forwardly in the pipe and in such instances the obstruction may be softened by use of water from the hose, and in operation, when the tool moves forwardly the detentmember or plate 16 will be pressed rearwardly in a manner to move the valve to open position to permit water to move to advantage against the obstruction to cause disintegration in a degree to permit removal It will be appreciated that the tool consists of few parts to permit convenient and economical production, and on account of its.

novel features of construction it will be effective'in removing obstructions from pipes having the curved forms mentioned.

I claimas my invention,

. 1. A pipe cleaning tool comprising anelongated-coiled spring provided with a handle at one of its ends and having a tapered form in outline from its handle toward its opposite end.

2. A pipe cleaning-tool comprising an elongated wire coil provided with a handle at one of its ends, a flexible hose disposed in the coil and having a valve arranged to permit a discharge, of liquid at that end of the wire coil opposite to the handle.

3. A pipe cleaning tool comprisinga wire bent to provide an elongated coiled part and a handle at one end of the coiled part, a valve-housing having a discharge port and disposed in that part of said coiled part opposite to said handle, a detent-ring on the valve-housing having projections extending outwardly of said coiled part, a valve in said housing having a buffer-member extend: ing outwardly of said discharge port, and a hose disposed in said coiled part adapted to communicate with the valve-housing for conducting a liquid thereto.

Intestimony whereof, I aflix my signature.-
