IMPROVEMENT IN BINKS.

TO'4 ALL WHOM ITMAY CONCERN:

Be it known that I, HUGH II. CRAIGIS, ot` the city and State of New .Yorin-have invented, made, and

applied to use a certain nen and useful Improvement in Sinks; and I do hereby declare the kfollowing to be a full, clear, and exact description of the said invention, reference 4'being had to the annexed drawing, making part'of this specification, \vhereinp Figure 1 is an inverted plan of the'sink; and

Figure 2 is a vertical section'atthe line a: 2:, showing the trap and pipe.

Similar letters denote the same parts. l

Sinks have heretofore been i'ormed with a bent pipo to retain water and form a trap to the sewer pipe.. This is liable to become choked, and, being ot' necessity some little distance below the sink, is liable to injury from poils, pots, or other kitchen utensils that arfe often placed in a closet that is formed under thcsink. In makingl the attachment between tbe iron ferrulc and the lead pipe a flange with bolts and nuts has usually been employed; but this device is costly and unsightly.`

The nature of my said invention consists in a trap formed by a cup attachedto the under sideof the sink,

into which a fen-,ale from the sink passes, and terminates below the water line in said cup. y The escupe pipe `passes o' from the side of this cup `in the form of o bond, so that the pipe to the sewer can 4he vertical and close against the wall; and I unite the iron and lead pipo by dressing the soft-metal pipelinto a contraction or neck in the iron pipe and driving over it a metal ring, which makes ahvcryrstrong, tight, and nent joint, because the neck receiving the soft-metal pipe prevents the joint becoming loose by concussion or strain, because the pipe cannot draw o said neck neither can the iron pipe slide further into the lend pipe, the neck holding thegpipes together, and preventing a movement in either direction.

In the drawing, a represents the sink, of any desired size` or shape; b is a ferrule formed below the grating or strainer v, and d isthe cup forming the trap. This cup is attached to the under side of the sink by means of wedge-shaped lugs e e cnteringbetn'een lips or projections upon the under side of the sink.` fis the bend passing oft' from the side of the cup d, and terminating near the back of the sink, so that the pipe g, leading to a cesspool or sewer, .may stand vertically, or nearly so, against the wall or support against which the sink is placed. The pipe g is attached to -thc iron pipe f by thesaidppef being entered within the end of the pipe g, the ring h being tirstlipped on. The soft-metal pipe q is then hammered or pressed down into a recess or neck, i, around the end of the pipe and the ring driven over the end of the pipo g, secures the parts firmly and tightly togethcr. p

What I claim, and desire to secure by LcttersPatenqis- A l. A trap for sinks, foruicd by the detachable cup d, attached to the under side ofthe sink, in combination with the downnarlbprojecting ferrule or pipe b, as and for thepurposes set forth.

2. I claim the bendf and trup d; in combination with the stift-metal pipe g, connected to the bend f by the ring l; and neck, substantially as and for the purposes set forth. f t

In witness whereof I have hereunto set my signature this 19th day of January, A. D. 1867.

HUGH H. CRAIGIE.
