WASTE-PIPE STRAVINER.

SPECIFICATION forming part of Letters Patent No. 738,726, dated September 8, 19,03. i Application iled December 26, 1902. Serial No. 136,612. (No model.)

To will whom it may con/cern,.-

Be it known that LALBERT E. LYTLE, a citizen of the United States, residing at Chicago, inthe county ofH Cook and State of Illinois,

have invented certain new and useful Improvements in Strainers for Waste-Pipes, of which the following is a specilication.

This invention relates to improvements in a strainer to be used in connection with the io waste-pipes of sinks and other basins; and it consists in certain peculiarities of the construction, novel arrangement, and operation of its parts, as will be hereinafter more fully set forth and specifically claimed.

I5 The principal object of my invention is to provide a strainer which shall be of such construction that it will permit of the free escape of Water from the sink or other vessel,

. yet will prevent the accumulation of bits of 1 2o papers, toothpicks, burned matches, coecz5 iiow, as is usually t-he case when the strainers heretofore in use have been employed.`

Other objects and Vadvantages of the in vention will be disclosed in the subjoined vdey' scription and explanation.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanyingdrawings, in which- Figure l is a perspective view of a `portion of a sink and apart of the waste-pipe thereof, showing my improved strainer in position.`

Fig. 2 is an enlarged central sectional view the different views of the drawings.

A represents a portion of a sink, which may be of the ordinary or any preferred construction and, as usual, is provided with a screwthreaded opening a, in which the waste-pipe B is secured. Surroundinglthe opening a 5o and on its lower surface the bottom of the sink or vesselA is provided with a screwthreaded neck b to engage the waste-pipe and a lock-nut b', used to more securely hold the waste-pipe in position. The upper surface of the bottom of the sink or vessel A is usually formed with a recess a' around the opening a to receive the ordinary perforated and hat strainer plate, which, as is Well known,is secured in place by means of screws, 6o which soon become corroded and rusted to such an extent that they cannot be removed when it is desired to remove said plate. I't is therefore one of the objects of my invention to provide a strainer which can be `easily detached to permit of it being cleaned, but when iu position for use will be firmly held against accidental dislocation. The strainer consists of a balloon or pear shaped body C, having a series of perforations c andat its lower por- 7o tion a number of upwardly-extending slots c', which preferably taper Vtoward their upper ends. The tapered lower portion of the body C is provided with an annular iiange c2, which rests in the recess a', from which the ordi- 75 nary strainer-plate has been removed, so as to be iiush with 'the upper surface of the bottom of the sink. The lower surface of the iiange c2 is provided with a neck c3, of any suitable length, to t within the upper por- 8o tion of the waste-pipe B, thus further securing the strainer in place and so as to prevent it tipping over. As shown in Fig. 2 of the drawings, the neck c3 surrounds the opening c4 in the lower end of the strainer-body. In 85 Fig. 3 of the drawings I have shown a modified form of the strainer, which consists in making it of two pieces C and C2 instead of one piece, as shown in Figs. 1 and 2 of the drawings. Each of the -pieces C' and C2 is 9o provided at each of its sides with lugs CZ, through which are passed screws orfrivets d', used to hold the pieces comprising the strainer together. For the convenience of manufacture I prefer to make the strainer of two pieces, but do not desire to be limited to such a construction. In Fig. 4 of the drawings is shown still another modification,which consists in omitting the ange c2 andalso the perforations c, yet employing the upwardlyextending slots c' and neck c3 to fltin the upper end of the drain-pipe oropening inthe bottom of the basin or Vessel.

From the foregoing and by reference to the drawings it will be seen and clearly understood that by using a strainer embodying my invention the water will be allowed to escape at all times, and as it passes throughy the slots c the accumulations of the bits of paper,coeegrounds, and thelike will be caused to settle around the lower portion of the body by reason of its inwardly-tapered shape, thus preventing the openings becoming clogged, so as to cause overflow of the basin or vessel. It is also apparent that the strainer may be readily removed when it is desired to clean the same and easily replaced.

Having thus fully described my invention, Y

what I claim as new, and desire to secure by Letters Patent, is- A 1. As an improved article of manufacture, a strainer comprising a perforated body portion tapered toward its lower part and pro- .vided at its lower portion with an annular tending slots, an annulaiange on its lower portion, and a neck on the lower surface of said flange, substantially as described.
