URINAL.

SPECIFICATION forming part of Reissued Letters Patent No. 9,427, dated October 19, 1880,

Original No. 136,105, dated February 18, 1873. Application for reissue filed September 14, 1880. DlvlsloN C.

To all whom 'it may concern Be it known that I, ROBERT D. O. SMITH, of Washington, in the District of Columbia, have invented a new and useful Improvement in Urinals; and I do hereby declare that the following is a full and complete description of the same.

Heretofore apartments have been ventilated by means of shafts or ues connected therewith, through vwhich an upward flow of air has been produced by heat, fans, or other artificial means when the required current wonldnot be produced by natural causes and I am aware that the ventilation of sewers has been at tempted in a similar way.

I am also aware that a urinal has been provided with a pipe at its upper part and a an ge or hood extending laterally therefrom above the bowl of the urinal, and with another pipe extending'up the back of the urinal, but open at both upper and lower ends, for the alleged purpose of Ventilating said urinal, said firstnamed pipe being connected with a ventilating ue or duct. The well-known law by which fluids in motion ow along the shortest lines, or lines of least resistance, makes it evident that the air withdrawn from the urinal by saidventilating-pipe will be exhausted from the immedate vicinity of the hood or flange at the top of the urinal, instead of from the bottom, in the immediate vicinity ofthe escape-pipe, from which foul odors do and will escape.

The object of my invention is to cause a current of pure air to pass in front of, over, or through the orifice by which the urine or other iiuid matters escape from the urinal into the waste-pipe, so that any and all foul odors or gases arising out of said waste-pipe will be deected and carried into the Ventilating-pi pe, instead of escaping by lateral di'usion into the apartment; and it therefore consists iu a urinal provided with an outlet for urine and a `ventilatingpipe arranged with respect to said fluid-outlet, so as to cause a current of air to ow in close proximity, in front of, over, or through said duid-outlet, and thereby cause all gases escaping therefrom to be deflected into saidventilating-pipe, to be carried away by the Ventilating current.

That others may fully understand my inven- 'waste-pipe whereby the urine, &c., is conveyed away. C is an ordinary stench-trap.

D is a ventilating-outlet adapted to be connected with a suitable Ventilating ilue or duct, whereby a current of air may be caused to flow through said bowl A to ventilate the same.

The characteristic odor of urine in the vicinl ity of a urinalis largely due to the ammonia set free in its decomposition, which is highly volatile, and therefore possesses great power of dil'usion. If, therefore, these odors are permitted to escape from the vicinity of the wastepipe, it is impossible to regather them. By means of my invention they are captured immediately, and are not permitted to escape into the apartment. To accomplish this purpose I prefer to extend the Ventilating-pi pe, as at s, down and over the outlet into the waste-pipe B, leaving an opening, p, at the bottom of said ventilatingpipe for the common passage iu the same direction of the fluids for escape into the waste-pipe and air for the Ventilating-pipe. The Ventilating-pipe will cause this inward ilow of air to be constant, and it will pass in close proximity in front of or over the orifice of the waste-pipe, so that the gaseous emanations arising from said waste-pipe cannot escape toward the bowlAand to the apartment without doing so in opposition to said inilowing air-current.

In Fig. 2 a modied structure is shown, which may be preferable in some places, but which does not introduce any new principle of operation nor any modification in the mode of action. In this case the Ventilating-outlet is placed below instead of above the wasteoutlet, so that the Ventilating current of air passes through said outlet and with the escaping tiuids for a short distance.

It is intended to reserve from this patent all matters covered or which might be covered by reissue of the original patent of which this is a division except that which relates specifically to urinals.

Having described my invention, what I claim as new isl. A urinal provided with a Waste-pipe orifice adapted to be connected to a waste-pipe, combined with a Ventilating-outlet adapted to be connected with a Ventilating pipe or flue, and so located that the inflowing Ventilating current of air will pass in close'proximity to the waste-outlet, and thereby deilect and carry into the ventilatingpipe all gaseous emanations from the waste-pipe, as set forth.

2. A urinal provided with a bowl, A, and an outlet at its bottom for the escape of urine,

sists in causing a current of pure air to pass in close proximity to the waste-outlet, and then into a Ventilating or exhaust outlet, substan- -tially as herein described.
