Application April 19, 1945, Serial No. 589,221

This invention relates to a pipe cleaning means and it is primarily an object of the invention to provide means of this kind wherein the cleaning element is confined within and constitutes substantially a permanent fixture with respect to the pipe with which it operates.

It is also an object of the invention to provide a pipe cleaning means embodying an element which extends a desired distance within the pipe .to be cleaned and wherein said element is mounted for both rotary and endwise movement to assure maximum efiiciency oi the element.

A further object of the invention is to provide a pipe cleaning means including an elongated member which extends a desired distance within and along the pipe to be cleaned and which is provided with means whereby the cleaning member can be readily and conveniently operated from without the pipe, whereby an effective and convenient arrangement is provided to enable the occupant of the building to clear the pipe of any interfering obstruction therein without the necessity of calling upon the services of a skilled artisan.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved pipe cleaning means whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view partly in elevation and partly in section of a diagrammatically illustrated portion of a building showing the application of the.

present invention.

Figure 2 is a longitudinal section through a portion of the drain pipes, showing the present invention applied thereto and partially in section.

Figure 3 is a perspective view illustrating the coacting pin and cams.

As illustrated in the accompanying drawings, F indicates a floor of the building including the usual joists or beams I from which is supported in any conventional or preferred manner a carryofi pipe or conduit 2 of required size and which 6 Claims. (01. 15-242) has its outer end formed to provide a convention-a1 hell or flare 3. The opposite end portion of this pipe 2, as herein embodied, is continued by a downwardly inclined extension pipe 4' disposed on a predetermined angle and this extension pipe l, as illustrated in the drawings, is continued by a downwardly directed vertical extension pipe 5 leading to and in communication with a sewer pipe 5 or leading to any other desired point of discharge.

Tightly packed in a manner as may be preferred within the hell or flare 3 of the pipe 2 is a plate I of steel or any other material possessing the requisite strength and threading through the central portion of this plate 1 is a nipple 8. It is believed to be readily apparent that this nipple 8 may be attached to the plate 1 in any other manner as it is only required that such securement of the nipple 8 to the plate I be rigid.

Threading upon the outer portion of the nipple 8 is a coupling collar 9 which also operatively engages the inner end portion of an elongated tubular member II] which, as illustrated in the accompanying drawings, is of a length to extend through and slightly beyond a side wall W of the building structure.

Held between the opposed ends of the nipple 8 and the member I0 is a rigid disk H having therethrough at its axial center an opening [2 through which freely but relatively snugly passes the outer straight end portion I4 of the cleaning element E. This portion I 4 is also of a length to pass out through a central opening IS in a cap I6 for the outer end of the member I0. This cap l6, as herein embodied, may be removed when desired in order to allow access within the member In when desired.

The portion i4 also normally extends a distance outwardly beyond the applied cap I6 and at a desired point inwardly of the cap it, this portion l4 has rigid therewith a surrounding flange or head l7. Interposed between this head I! and the cap I6 is an expansible member ll! of required tension and which is herein shown as a coil spring surrounding this extended part of the element E. This member or spring l8 serves to constantly maintain the element E at the limit of its endwise movement inwardly of the pipe 2 and to automatically return the same to such position after the element E has been moved outwardly endwise.

The extent of inward movement of the element E is limited by an outstanding pin is rigid with the extended part of the portion 14 and which ooacts with cams a on the outer face of the cap l6. These cams a. and the pin l9 coact upon rotation of the element E to cause the element E to have outward endwise movement while, of course, the element or spring is operates to afiect the inward endwise movement, so that during a working operation the element E, in addition to its rotary action, is having reciprocatory movement, whereby the efficiency of the element is materially increased.

The inserted end of the nipple 8, as herein disclosed, has threaded therein a plug having a central opening 2| through which the portion in of the element E freely but snugly passes and this applied plug 20 serves as aretainer for the packing 22 of desired character which is placed within the nipple 8 between the plug 20 and the disk H. The packing may, if desired, be otherwise placed or may be of any character which fully meets the requirements of practice as the features of the packing in itself forms no particular part of the present invention.

As illustrated in the accompanying drawings, the element E is of such a length as to extend entirely through the pipe 2, the extension 5 and a materialdistance inwardly of the extension pipe 5 and in order that this may be accomplished, the inner inserted end portion of the element E is articulated, the required joints 23 being conventional for this purpose.

The pipe 2, as herein disclosed, at its outer portion is provided with a lateral branch 24 into which discharges the drain pipe 25 leading from a sink S or other plumbing accessory and the portion of the element 3 from the branch 24 to the inserted free end thereof is alternately laterally offset in opposite directions to provide scrap ing elements '26 each of which has the outer straight portions c which closely approach the wall of the pipes 2, 4 and 5 so that, as the element E is rotated, the breaking up of any interfering obstructions will be efiected. This is further assured by the endwise movement of the element E which occurs during its rotation.

The extended extremity of the portion !4 of the element E is adapted to have engaged therewith a hand crank 21 or other desired operating member whereby the element E may be readily operated as desired and which operation is such as to be readily accomplished by an unskilled person, thus avoiding the necessity of calling upon skilled help should there be a sluggish discharge through the drain pipe 25.

It is to be particularly pointed out that the inserted end of the element E is free of any connection. This is of advantage because, during the rotation of the element E, it will of itself so spiral as to provide a means for conveying the released'foreig'n matter within the pipe toward the sewer pipe 6.

From the foregoing description it is thought to be obvious that a pipe cleaning means con structed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.
