IMPROVEMENT IN UTLETS FOR SINKS, &c.

Specificationformin g part of Letters Patent No. 149,489, dated April 7, 1874; application filed March 6, 1874.

To all whom it may concern:

Be it known that I, JASON LEWIS, of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in the Outlet of Sinks, 8vo., of which the following is a speciiication, referring to the accompanying drawing making part of the same, in which- Figurel is a vertical section of a trap-outlet of a sink with my said improvement. Fig. 2 is a plan or top view of the same, with part ot' the strainer broken away to give an unobstructed view of the parts beneath it. Figs.

` 3 and 4 are details of the application of my improvement to the nozzle H, hereinafter fully explained. Figs. 5 and 6 are details of the screw and cross-bar, also herein fully explained.

Similar letters mark like parts in all the JrigllleS.

My invention relates to the means for fastcnlng the strainer over the outlet of the sink in a simple, cheap, and effective manner; and

consists orn a screw passing through the center of the strainer, and screwing into the middle of a removable crossbar extending across the outlet, the object being to secure the strainer in its place, so that it may be readily removed for clearing the trap and outlet of any obstructions, but in a manner that requires no drilling or tapping of holes into the cast-iron sink or outlet, so that all diftcult handling of the heavy sink for such purpose is avoided, and that requires no change in the construction of the parts, except two slight notches in the outlet, whereby `all difficulty of casting and imperfection of the same are entirely avoided.

In the drawing, H is the outlet, and A is the surrounding basin, of a cast-iron sink, forming part of the cast-iron bottom ofthe same. S is the strainer, having a dome above, and a lange, F, beneath, extending below the upper edge c of the nozzle or out-let H,

4into the said basin A, to form a stench-trap,

in a manner well known, besides stiftening the strainer to resist blows and pressure upon it.

In order that the strainer shall exclude ob structions and the trap offensive smells, it must be secured in its place over the outlet. This has been done in anumber of ways heretofore, but none of which, so far as I am aware, without some kind of objection, most of which by this invention of mine I have been able to overcome or avoid altogether. This is accomplished by providing a cross-bar, D, across the outlet H, which is made separately from the sink casting, and preferably ot' brass or incorrodible metal, and is held by its ends in two dovetail notches, I, inthe lower edge of the outlet H, as shown in Figs. l and 4f.4 These notches are rst east in the form shown in Fig. 3, so as to readily draw from the mold, and are afterward filed into the dovetail form, and after the cross-bar D is in serted thereinit may be permanently secured in its place by spreading the ends of the crossbar by hammering it. In the middle of the crossbar a hole is drilled and tapped, into which the single screw T, which passes through. the center of the strainer,`is screwed, the head of the screw bein g eountersunk in the strainer, and by sett-ing up the screw the strainer is secured in its place.

This device is extremely simple, but its utility will be fully understood and appreciated when it is considered that it is almost impossible to cast a cross-bar likel D across the nozzle, owing to its liability to come iniperfect, and thus spoil the whole sink; and even it' these could be cast perfect, the whole sink would have to be lifted and handled and properly mounted to drill and tap the hole in the cross-bar for the screw T, which in the separate crosslbar is entirely avoided, and the work is greatly simpliiied and cheapened with out necessity of changing the construction of the sinks pattern, except in the matter of the notches, whereby it is readily applied to any sink nozzle or outlet.

The waste-pipe is secured upon the outside of the nozzle H to lugs provided for the purpose, or in any well-known and effective man ner.

Having described my invention, I claim- The screw T and cross-bar D, in combination with the strainer and outlet of the sink, as described, when arranged and applied thereto substantially in the manner and to eiiect the purpose specified.

JASON LEWIS.
