YYILLIAH M. MIXER, OF NEW YORK, N. Y.
PiPE-COUPLING.
SPBCTPICATION forming part of Letters Patent No. 301,512, dated July 8, 1884.
Applicaiion filed December 15, 1883. (No model.) i
To aZZ whom it may concern Be it known that I, VVILLIAM M. MIXER, of
the city of New York, county of New York,
and State of New York, have invented a new and useful Improvement in PipeCouplings, of which the following is a full, true, and. exact description, reference being had to the accompanying drawings.
This invention relates to a simple method of making a tight pipe-coupling. This coupling is so arranged as to be reversiblethat is to say, either end of any pipe provided with it can be connected to either end of any other pipe similarly provided. This coupling is especially adapted to the retaining of ages or liquid under pressure, and is designed for use in connecting the refrigerating-pipes of ice-machines.
My invention will be readily understood from the accompanying drawings, of which Figure 1 represents perspective views of the coupling-plates and lead washer; Fig. 2, a sectional view of the joint completed, and Fig. 3 a view of the lead washer after it has been pressed by the coupling-plates.
A A representthe coupling-plates, which are screwed firmly upon the ends of the pipes B B, making a tight joint therewith; These plates are preferably generally square in section, and are provided with holes 0 for the reception of the bolts D. The central portionsof these plates surrounding the central opening are provided with circular ribs, as shown, while the outer parts around the ribbed portion are preferably cut away or beveled, so as not to interfere with the operation of the lead washer. The lead washer shown in l is circular in section, having an opening corresponding with the opening of the pipe, and when placed in position in making the coupling is held centrally by the bolts I).
In order to make the coupling, the ends of brought together.
the pipes provided with coupling-plates are The ring-washer, which may be made of lead or other compressible material, is placed in situation so that its hole corresponds with the opening in the pipe. The bolts D are placed in position, and are drawn up by their nuts, thereby pressing the washer E into the form shown in Fig. 3. By this operation the lead fills the grooves between the coupling ends, and an absolutely tight joint is insured. The lead in position is visible from the outside, thereby preventing a work man from accidentally omitting it in-nia-king a joint. It will thus be seen that the central portion of the coupling-plate, or that por- -tion nearest the tube, having the annular grooves, projects beyond the periphery or edge of the plate, the face of the plate being beveled near its periphery, as shown in Fig. 2. That I claim as my invention, and desire to secure by Letters Patent, is 1. The combination of the coupling-plates A A, each provided with central circular ribs, with. lead washer E, filling the grooves between said ribs, substantially as described.
2. The combination of the pipes B 13, each having at each end a coupling-plate, A, pro
vided with central circular ribs, the lead WILLIAM M. MIXER.
