VENTILATOR-CAP.

SPECIFICATION forming part of Letters Patent No. 445,522, dated January 27, 1891.

Application filed December 9, 1889- Serial No. 333,053, (No model.)

To all whom it may concern:

Be it known that I, J GEN DELLINGER, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Ventilator-Caps, of which the following is a specification.

My invention consists in certain improvements in ventilator-caps, whereby the ventixo lator is rendered very much more simple in its construction and the cap more easily put in place or attached to a pipe than such caps as are in ordinary use, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a detached sectional ele 'ation of the ventilator through line a b, Fig. 4:, looking toward the lowerhalf. Fig. 2 is aside elevation of the ventilator attached to a piece of pipe. Fig. 3 is a similar view showing the pipe in section, and Fig. 4 is an inside plan view of the ventilator-cap.

Referring to said drawings, 1 represents the 2 5 ventilator-cap. I have shown it in a semispherical form; but a conical or any other suitable shape may be used. This cap is preferably made of cast-iron having three or more lugs 2 on the inside cast in one piece with it. In each lug 2 1s a notch or offset 3, therebyleaving a projecting shoulder on each lug 2 to slip over the edge of a piece of pipe when the ventilator is in place, as shown in Fig. 1. This construction affords a suitable bearing to rest upon the top of the pipe and the shoulders on the lugs to keep it in a central position, substantially as shown by the dotted lines 4 in Fig. 4L. Between the lugs, or at some convenient point, are riveted by rivets 5 the strap-iron pieces 6. I have shown three in the drawings, but more or less may be used, if desired. When the cap is attached to a pipe, these strap-irons 6 are slipped down inside of the pipe 7 and then turned up over the lower'edge, as shown at S in Figs. l and The object of this invention is to produce a simple ventilator-cap adapted for easily and readily being attached to a pipe to be connected with a sewer-pipe in the usual way, The strap-iron connecting-pieces 6 can be made of any desired length, and if too long for the pipe can be easily cut the proper length to fit, being of light strap-iron, and then attached by bending the ends over the lower end of the pipe, as before mentioned. The lower end of the pipe, having, the top thus secured, is placed in the well-known opening of an ordinary sewer-pipe, its bottom resting on the inwardly-projecting shoulder. The opening between the sewer-pipe opening and around the pipe is then filled up by cement, thereby forming a perfectly-tight joint in the usual and well-known manner.

I claim as my invention- In a ventilator-cap, the combination of the cap 1, interior lugs 2, each having a notch or offset 3, strap-iron connecting-pieces 6, and the pipe 7, the connecting-pieces 6 connecting with the cap and with the pipe by passing down through it and terminating in the hook-shaped portion 8, which turns up over the lower edge of the pipe, substantially as described.

JOHN DELLINGER.
