To all whom it may concern: 7
Be it 'known that I, \VILLIAM G. STEWART, residing at Cleveland, in the countyof Cuvahoga and State of Ohio, have invente a certain new and useful Improvement in Sink Connections, of which thefollowingis a full, clear, and exact description, reference being had to the accompanying drawings:
So far as I am aware, the universal manner of securing strainers in place above the waste pipeconnections for sinks is to provide a pair of diametrically opposed openings in the strainer plate, near the peri hery thereof, and to'insert bolts therein, sai bolts extending through openings rovided in the bottom of the sink at'the .ec ge of the funnel-shaped outlet provided therein. The lower ends of thesebolts pass through lugs or wings projecting from a concave annular disk which surrounds the upper end of the lead bend, nuts being provided for the lower ends of said bolts, by. the tightening of -which the strainer is held in place and the upper end of the lead bend is supported in operative relation to the outlet. In forming such bolt openings in the bottoms of modern enameled sinks, it frequentlv happens that the enamel is cracked, thereby spoiling the' entire sink bottom, resulting in considerable waste of time, labor, and material.
The object of my invention is to provide a new connection between the sink bottom and the lead bend, whereby'the strainer may be secured in place without the necessity for perforating the bottom of the sink and a simple and effective connection between such bottom and the lead bendmay be secured. I accomplish these objects by the construction illustrated in the drawings, wherein Figure l represents a vertical sectional view through the outlet of a sink bottom, the strainer, the waste pipe, and-the connection which I employ between said outlet and waste pipe; and Fig. 2 represents a planview of the parts shown in Fig. 1, a portion I of the top of the strainer being broken away.
Describing the parts by re rence numerals, 1 represents aportion of the bottom of a sink of ordinary construction, said-bottom having a coating of enamel 1 .and. 2 the funnel-shaped outlet therefrom. At its eriphery, the outlet 2 is provided with a edge 3 forming a seat for the strainer 4; 5
denotes a short length of pipe of brass or similar material capable of retaining a thread, said pipe being provided at its up per end with a funnel-shaped inlet 6 adapted to fit within the correspondingly-shaped outlet 2. e or funnel-shaped inlet 6 with the body of the pipe, the exterior of said pipe is pro- ,vided with a screw thread 7 for the reception of a nut 8, the upper face of which is Below the junction of the'flaring adapted to engage the lower end of the fun- 6 nel 2, drawing the upper flaring end of such pipe into engagement with the inner surface of said funnel 2... In order to form a tight joint, an suitable packing material such as white ead or putty, may be insertet between such surfaces.- I
In order to secure the strainer in place, the upper end of the: connection 5 is provided with a pair of lugs 10 projecting inwardly from the periphery thereof, said lugs being 7 preferably diametrically opposed to each other. Each of said lugs is provided with a threaded bore 11 for the reception of the lower end of a screw 12', whlch extends through a corresponding perforation 13 in the strainer. The heads of the screws are preferably flat, whereby they may be'fluslr with or slightly countersunk fromthe up I per surface of the strainer.
To make a proper connection betweenthe 5 pipe 5 and the upper portion 15 of the lead bend or waste pipe, I make use of the following construction:A sleeve 16 is provided near the lower end. thereof with a squared projection 17 for the application of a wrench. At its upper end, sald sleeve is 1 provided with an exterior screw thread 18.
The interior of said sleeve is beveled or flared outwardly toward the top to provide a tapered seat 19 for the upper end of the lead waste pipe. 20 designates a gland comprising an inwardly projecting shoulder 21 adapted to loosely surround the pipe 5, and
22 represents the depending skirt of said;
gland provided with an interior thread 23 adapted to engage the exterior thread 18 on the sleeve 16. In assembling, the gland .20, having thereinone or more packing rings 25, is slipped over the lower end of the pipe 5.
The sleeve 16 is slipped over the upper end 15 'of the lead waste pipe, and-sald upper end is then flared outwardly at 24, as shown in Fig. 1, to bring its upper end into sub-' stantial engagement with the tapered surface 19 of said sleeve. The gland 20 is then screwed'down upon the upper end of the sleeve 16, forcing the packing ring or rings into engagement with the upper end 15 of the waste pipe. These rings should closely fit the outer surface of the pipe 5. Two such rings are shown, the upper one being fiat and adapted to be engaged by the shoulder 21, the lower one being tapered to engage the outwardly flaring surface 24 of the waste pipe. By simply tightening on the gland 20 the lower tapered ring is forced into the upwardly flared portion 24 of the lead pipe and a tight joint is formed between the pipe 5 and the upper end 15 of the lead waste pipe whereby any leakage between said parts is avoided.
By the construction herein described, it will be apparent that I am enabled to secure the strainer in place without the necessity for providing holes in the bottom of the sink and at the same time I am enabled. to form a tight connection between the sink and the lead waste pipe.
Having thus described my invention what I claim as new and desire to secure by Letters-Patent is 1. The combination, with the outlet of a sink, of a leaden waste pipe therefor having its upper end flared outwardly, a tubular connection of rigid material the lower end whereof is of less diameter than the upper end of the Waste pipe and projecting into the upper end of the waste pipe, a gland surrounding said connection and having a depending interiorly threaded sleeve and an inwardly projecting shoulder, a sleeve surrounding the upper end of the leaden waste pipe and extending along the same and having the inner surface formed with a long outward flare and having its upper end pro vided with an external thread for en agement with the thread on the gland s eeve, and packing interposed between the gland shoulder and the upper end of the leaden pipe and extending into the space between the flared end of the said leaden waste pipe and the tubular connection.
2. A pipe coupling comprising a lead pipe having its end flared outwardly, a tubular connection of rigid material the end of which is of less diameter than the bore of the lead pipe and projecting into the flared end thereof, a gland nut surrounding said connection and having an interiorly threaded sleeve and an inwardly projecting shoulder, a sleeve surrounding the end of the lead pipe and extending along the same and having a portion of its inner surface shaped to surround the flared end of said lead pipe, said sleeve being provided with an external thread for engagement with the thread on the gland nut, and packing interposed between the shoulder of the gland nut and the flared end of the lead pipe and extending into the space between the flared end of the lead pipe and the tubular connection.
In testimony whereof I afiix my signature in the presence of two witnesses.
