SINK ATTACHMENT.

Patented Dec. 18, 1906.

Application filed June 6, 1906. Serial No. 320.459.

T0 aZZ whom it may concern:

Be it known that I, ANTHONY A. FIOENER, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Sink Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a drain-pipe conneotion and strainer attachment for sinks; and its objects are to simplify and improve the mechanical construction and promote the sanitary condition of the drainage of the sink, and especially to dispense with the use of screws or bolts or similar fastenings for attaching the strainer, and to provide simple efficient means for connecting the drainpipe and fastening the strainer in such manner as to avoid leakage and to permit ready removal of the strainer for cleansing the parts. These results are attained by means substantially as hereinafter described, and more particularly pointed out in the appended claims, reference being made in the description to the accompanying drawings, which form a part of this specification, and wherein the same reference-numerals apply to corresponding parts in the different figures.

In said drawings, Figure 1 is a central vertical section through an attachment embodying my invention. Fig. 2 is a similar view showing a modification in the thimble or funnel, which is seated in the bell in the bottom of the sink. Fig. 3 is a top plan view of the construction, showing half of the strainer in plan view, the remaining half of the strainer being out oif. Figs. 4, 5, 6, and 7 are perspective views, respectively, of the strainer, thimble, bell, and tailpiece of the drain-pipe shown arranged in position one above another for assembling the parts, so that the four figures show an unassembled view of the elements of the construction.

Referring for more specific explanation to the drawings, the bottom of the sink (not shown) is constructed either integrally or otherwise with the usual bell, (designated by the numeral 1.) This is the ordinary funnellike part formed or provided in the bottom of the sink, having an upper flange or rim 2,

constituting an annular seat or depression for countersinking the strainer. According to the usual construction the lower end of the bell is commonly united or coupled with the drain-pipe, and the strainer is secured in the bottom of the sink within the annular seat 2 by means of screws or bolts. In this improved construction a metal thimble or funnel-lke part 8 sits within the bell 1, the lower end of said thimble extending as a short exteriorly-screw-threaded tube down through the bottom of the bell to receive a nut, tube attachment, or coupling, according to the particular mode of uniting the drainpipe to said thimble. In the present case a nickel tube or tailpiece 4 is shown screwed on the lower end of said thimble, the said tailpiece having an upper flanged end screwed tightly against the bottom of the bell 1, making a tight connection. The thimble is seated within the funnel-shaped or cup-shaped part of the bell below its upper rim or flange 2, and the top of said thimble is formed or provided with an interior annular shoulder, rim, or flange 5. The strainer 6 is a circular plate, preferably of sheet metal, resting in the seat afforded by the rim 2, being thus countersunk in the bottom of the sink in the usual way, and the central apertured or reticulated portion of the strainer, supported on or directly over the mouth of the funnel 3, is preferably depressed or concave to lie within the mouth of the funnel or thimble, as shown. By means of lugs or tongues 7, engaging within or under the flange 5 of the thimble the strainer is easily and securely fastened in place. The said lugs or tongues are desirably cut from the sheet metal plate forming the strainer and are bent down to engage under the shoulder 5, so that in fastening or unfastening the strainer its said lugs or tongues snap past and engage with or disengage from the shoulder. Besides being a nice mechanical construction, very simple and efficient, this arrangement obviates the use of screws or bolts for fastening the strainer, thus doing away with holes in the bottom of the sink for receiving such bolts, screws, or other fastenings. The strainer can be readily removed simply by lifting it out, sov that the outlet at this part of the sink can be more easily accessible for cleaning and for keeping the drainage in sanitary condition. Afurther advantage is that when the sink is put in place by the workman it is a simple matter to connect it with the drainpipe, and there is no danger of any leakage by reason of absence of bolt-holes in the bottom of the sink. With this improvement there is no obstruction to the free drainage of the sink.

It is understood that the bell 1 may be manufactured as a separate part for screwing in the bottom of the sink, or the said bell may be integrally cast or formed with the bottom of the sink, in which case its flange or rim portion 2 would simply be an annular seat or countersink in the bottom of the sink, and the following claims are to be construed with the foregoing in mind. The thimble or funnel 3 is preferably made solidthat is, with solid walls-as shown in Fig. 1 and in Fig. 5; but, if preferred, said thimble may be formed with slots or openings therein, as shown in Fig. 2. These and other modifications as to details may be made within the scope of the invention.

The construction described, while more particularly designed for sinks, may also be applicable to tubes, tanks, and basins, and in such case a suitable plug would be provided for closing the strainer when desiring to close the outlet.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a drainage construction for sinks, the combination of a bell forming or adapted to form a part of the bottom of the sink, a thimble or funnel seated in said bell, and adapted for connection with the drain-pipe, and a strainer seated over or upon the bell and having depending lugs engaging the bell interiorly.

2. In a drainage construction for sinks, the combination of a bell, a thimble or funnel seated therein, said thimble having an interior shoulder within its mouth or upper portion, and a strainer seated over the mouth of the thimble and having bottom lugs engaging said interior shoulder.

3. In a sink attachment, the combination of a bell, a thimble or funnel seated therein having its lower end protruding below the bell and adapted for connection with the drain-pipe, said thimble having an interior annular shoulder within its mouth or upper portion, and a sheet-metal strainer seated over the thimble and having tongues or lugs cut and bent down from itself and engaging under said shoulder, said tongues or lugs being adapted to snap past said shoulder to engage with or disengage therefrom.

l. In a sink attachment, the combination of a bell having an upper rim around its mouth constituting an annular seat for countersinking a strainer in the bottom of the sink, a thimble or funnel seated in said bell having an upper interior annular shoulder, and a sheet-metal strainer resting in said annular seat and having tongues or lugs cut from the sheet metal and bent down to engage under said shoulder, said tongues or lugs being adapted to snap past said shoulder to engage with or disengage therefrom.

In testimony whereof I afIiX my signature in presence of two witnesses.
