JOHN H. LONSKEY, 0F DETROIT, MICHIGAN, ASSIGN OR TO THE IDEAL MANUFACTUR- ING COMPANY, 013 DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.

PIPE-FITTING.

T 0 all whom it may concern:

Be it known that I, JOHN H. LONSKEY, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented cer tain new and useful Improvements in Pipe- Fittings, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates particularly to a soil pipe fitting designed for use at the base of a soil stack, and consists in the novel construction of a stack bend, and in the peculiar arrangement and combination of parts as hereinafter described.

In the drawings,-Figure l is a vertical central section through a pipe fitting embodying my invention; Fig. 2 is a rear elevation thereof, partly in section; and Fig. 3 is a view in section and plan of the closure, the parts being detached.

A represents the main section of the fitting, or elbow, as it will be hereinafter termed, forming the connection between the soil stack and sewer line, which in configuration is substantially a quarter bend. Connecting with the elbow and projecting upwardly therefrom beside the stack end of the fitting is a cleanout section B provided at its upper end with a removable closure C. The purpose of this latter section is to permit the cleaning of the bend or the testing of the stack to be effected in the usual manner after the connect-ion between the stack and sewer has been made, which obviates the necessity heretofore existing of disconnecting the parts at the time of making the test.

The closure is of novel formation, and in addition to serving as a cover or cap for the cleanout forms a means of connection between the latter and the usual testing hose. In construction, it comprises a plate or cover proper D having oppositely-disposed pairs of separated lugs a formed on its under face and an annular groove 6 to receive a suitable gasket or packing 0 adapted to bear against an annular rib (Z on the end of the cleanout section.

Specification of Letters Patent.

Application filed October 1, 1909.

Patented Mar. 28, 1911. Serial No. 520,526.

E is a cross bar having a central opening 6 and oppositely disposed projections f adapted to engage beneath corresponding lugs g upon the interior of the section B. F is anipple having screw-threads upon its opposite ends adapted to engage a screwthreaded opening it formed in the cover proper and projecting loosely through the aperture 6, and G is a cap for closing the outer end of the nipple, the latter constituting a hose connection.

H is a connection for an outside closet communicating with the interior of the bend or elbow proper preferably through the cleanout section B, as plainly shown in Fig. 1. For preventing the siphoning of the closet trap, a vent connection I is formed in the fitting preferably within the side wall of the cleanout section, as shown, to which the usual vent pipe is connected.

T have shown the fitting in the form of a unitary structure, and preferably provide a support or brace for the bend immediately beneath the upper or stack end of the fitting for supporting the stack. The support preferably comprises a depending lug or stud J upon the lower wall of the fitting in the position described, a socket member K, and a support proper L formed of a section of pipe seated within the socket and loosely engaging the lug J, as shown. Such a support maintains the fitting under the Weight of the stack, and at the same time may be conveniently removed when desired in the installing of the bend.

From the foregoing description, it will be seen that the bend is exceedingly simple in construction and obviates the necessity of using a number of fittings to form a connection between the stack and sewer. Furthermore, the cleanout section is in a convenient position to permit rodding or flushing into the sewer, and by reason of the long sweep that is provided by the cleanout section and the lower portion of the bend proper the cleaning may be very readily effected.

What I claim as my invention is,

1. A stack bend comprising an elbow section having a stack fitting, a lateral from the convex side of the bend and open closet connection, and a cleanont section 111g lnto the bend at a tangent thereto.

positioned intermediate the stack fitting and. In testimony whereof I aflix my signature lateral connection. in presence of two Witnesses.

2. A stack connection comprising a main JOHN H. LONSKEY. elbow section in the form of a quarter-bend, \Vitnesses: and a cleanout section formed integral with ANNA H. HEINRICH, the elbow section, projecting upwardly I JAs. P. FEELY, Jr.
