PHILIP A. FUCHS, OF MILWAUKEE, WISCONSIN.

PULLEY-SUPPORTING BRACE.

To all whom it may concern:

Be it known that I, PHILIP A. FUCHS, a citizen of the United States, residing at Milwaukee, county of Milwaukee and State of Wisconsin, have invented new and useful Improvements iny PuilleyeSupporlting' Braces, of which the following is a specification.

My invention relates to improvements in pulley-supporting braces for tube systems.

The object of my invention is to provide removable means for supporting a pulley near the bottom of a catch basin or man hole pit of a sewerage system or any other system of pipes or tubes in which it is desirable to draw cleaning apparatus through the pipes or tubes at intervals. My invention makes it possible to sup-port a pulley in such a position that a cable may be drawn through the sewer or horizontal pipe and passed around the pulley and upwardly to the exterior through a man hole or catch basin, whereby cleaning apparatus having another cable and a hose attached thereto may be guided into the sewer from another catch basin or man hole as the cleaning apparatus advances, the apparatus being advanced or retracted by means of the cables and the hose being used to deliver water to the apparatus for power or iushing purposes.

The drawing illustrates my improved apparatus in elevation as loca-ted for use within a sewer system, fragments of the sewer pipes and of a pair of man holes or catch basins being illustrated in vertical section.

In the drawings, each man hole or catch basin communicates at the bottom with pipe sections 2, 3 and 4 respectively. My mproved brace is formed in telescoping sections 5 and 6, the lower section 5 being pivotally connected at 7 with a shoe 8 adapted to rest upon the bottom of the sewer. The lower section 5 is also provided with a. bracket 9 in which a hook arm 10 may engage, this arm having swivel connection with a pulley block 11 in which a pulley 12 is journaled. The bracket 9 is preferably in the form of a staple, the two legs being passed through apertures in the section 5 of the brace near its lower end and threaded to receive the nuts 13.

The upper section 6 of the brace is provided with a series of apertures 14 adapted to receive a pin or bolt 15 which extends through a bolt receiving aperture in the Specification of Letters Patent. Patented dipl. 29, lllillldl.

upper end of section 5. In the drawing, this connection is illustrated as a bolt 15 threaded to receive a nut 16, whereby the sections 5 and 6 of the brace may be securely locked together. The upper end of the brace section 6 is flattened as illustrated at 17 and provided with a wedge shaped extremity adapted to engage against orbetween the bricks or blocks forming the wall of the man hole or catch basin.

By forming the brace in adjustable sections, it is possible to utilize it in catch basins or man holes which differ in diameter. The sections are of such length that the braces may be readily manipulated to the position in which they are illustrated in the drawings. The shoe 8 may be pushed into one of the sewer pip for a short distance, with section 5 of the brace extending upwardly therefrom in an inclined position. The section 6 of the brace may be extended in correspondence with the diameter of the catch basin or man hole and it may either be extended after the shoe 8 has been placed in position as illustrated in the drawing, or if desired, the section 6 may be adjusted to the proper position before inserting the brace. In either case, the section 6 will be extended sufciently to support the brace in an inclined position with its upper end in anchorage engagement with the wall of the catch basin or man hole.

The pulley 11 is supported by the brace in a position to receive an actuating cable 20 which cable extends from the cleaning apparatus 21 through the sewer pipe 3, around the pulley and vertically through the man hole 1. The pulley is adapted to receive the cable in such a. position that when the latter is drawn upwardly the force exerted upon the pulley will not only increase the pressure of the wedge shaped upper extremity against the wall of the basin, but owing to the proximity of the pulley to the lower end of the section 5, the shoe will be drawn forcibly downward into contact with the bottom of the sewer, due to the resultant force exerted on the pulley. The apparatus may be retracted by a retracting cable 22 extending to the rearward catch basin or man hole.

It will be observed that the cables are operated by means of windlasses 28 located above the respective man holes. Only one brace is required, when the apparatus is being advanced, viz: that at the man hole in front of the machine (shown at the left in the drawing). But where the apparatus is to be retracted, asimilar brace will be used in the other man hole. The hose pipe 24 may be coupled at intervals to the retracting cable 22, whereby the Cable may be utilized to withdraw the hose. In such case, the hose will be uncou-p-led from the cable as it reaches the exit, thus allowing the cable to pass around the pulley.

I claim:

The combination with a sewer cleaner, of a cable for drawing the saine through the sewer, a pulley supporting brace adapted to extend obliquely from the bottom of the sewer adjacent to the Inan-hole,\across the mannhole into Contact with its opposing wall, a pulley connected with the brace in a position to be supported thereby near the lower end thereof and adjacent tol one wall of the man-hole, said cable being extended around said' pulley and upwardly through the man-hole and adapted to draw the up# per endof the brace against the opposing wall, and the lower end of the brace against the bottom of the sewer, said brace having a pivoted foot. piece at its lower end, and an extensible section at its upper end terminating in a wedge shaped extremity adapted for biting anchorage in the wall of the man-hole.

In testimony whereof I affix my signature in the presence of two witnesses.
