HENRY O. BEARDSLEY, OF NEW DULUTH, ASSIGNOR TOOHARLES HURD, OF DULUTH, MINNESOTA.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 498,612, dated May 30, 1893,

Application filed April 2l, 1892. Serial No. 430.064. (No model.)

To all whom it may concern,.-

Beit known that I, HENRY C. BEARDSLEY, a citizen of the United States, residing at New Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements ,in Refrigerators, which are fully set forth in the following specitcation, reference being had to the accompanying drawings, in which- Figure l represents an edge View of the drain pipe and trap embodying my invention with a portion of the refrigerator in section; Fig. 2, a section of the same, taken on the line 2-2, of Fig. 1 Fig. 3, a side elevation of the trap, detached; Fig. 4, a plan of the same; and Fig. 5, an elevation of an upper or inlet pipe made of glass for the trap.

My invention relates to traps for refrigerators and consists in certain special features of construction, which I will proceed to describe in detail and will rthen point out more definitely in claims the specific improvements which I believe to be new and wish to secure by Letters Patent.

It is very important to keep the interior of refrigerators as dry as possible and so it is desirable to drainV off the water therefrom constantly, so as to prevent any accumulation. At the saine time it is absolutely necessary to prevent the entrance of air from the outside and so a trap, or some other device becomes important for the drain outlet.

In the drawings, A represents a refrigerator, and, a., the bottom of the ice chamber, a',

the back of the refrigerator, and, a2, the bottom thereof. Water will be formed in the ice chamber, of course, by the gradual melting of the ice and this water ought to be drawn off at once. To this end,a drain pipe or conduit is provided entering through the bottom of the ice chamber about midway of the refrigerator and extending down through the latter and the bottom thereof to discharge the drip water outside. This drain pipe, as shown in the drawings, is composed of two sections, an upper one, B, and a lower one, C, and between the two is a trap, D. The upper section B of the drain pipe is inserted in the bottom of the ice chamber, so as to take the drip directly therefrom and extends a little way below this bottom of the refrigerator and at its lower end is inserted in the upper end ot' the trap. The drain pipe may be located at any other point, if desired.

The trap D is m'ade of glass, or rather the 55 `body is of glass, east in one piece ofthe form shown in Fig. 3, with an outlet or neck, cl and d', at the respective ends, these outlet necks being set out of line with each other, as seen in Figs. 2 and 3. Each of the necks d, d is cast 6o With an external thread, which is to provide for the application of metal caps E and F respectively to. said necks, the caps being threaded properly to be applied thereto. The caps are provided with central perforations e 6 5 and f. The cap E is applied to the upper end of the trap, a rubber gasket, G, being placed on the upper end of the neck d and the cap screwed down tightly upon the gasket, the latter being somewhat Wider than the thick- 7o ness of the glass, so as to extendl in beyond the same, as seen in Figs. 2 and 4. The cap F is somewhat deeper than the cap E to provide for the application of a short glass pipe or tube, H, which is inserted in the bottom neckl of the trap and is provided with a circumferential flange or collar, h, adapted to iit against the lower neck of the trap when inserted in the latter. The cap F is then screwed upon the neck d', a rubber gasket, 8o I, being placed between it and the collar on the pipe H, so as to make a tightjoint and firmly secure the pipe in the trap. This pipe H passes through the central opening in the cap F and extends a little below the saine and enters the upper end of the section O of the drain pipe, as seen in Fig. 2, the latter being thence extended downward to and through the bottom of the refrigerator. v The upper section B of the drain pipe is inserted 9o in the upper neck dof the trap, and, of course, must be extended down a little below the upper end of the tube H, so as to providea complete water trap. The inner edge of the rubber gasket G hugs this pipe tightly and so provides a tight joint at this point of connection. The drip water fills the trap body B, or

it may otherwise be filled with water to the top of the outlet H, when, of course, the lower end of the pipe B will be covered and Ic'o so a complete water trap provided for the drain pipe, so that the drip water may be conveyed away immediately, as it is formed and at the same time the entrance of air is prevented.

As the trap is of glass the interior is readily seen and so it may be inspected at any time to determine its condition. It will be noticed also that the parts are all readily disconnected for cleaning, repairs, or any other purpose, but the trap may also be made with the parts non-detachable, if desired. The trap may be' removed bodily by simply slipping it upon the upper pipe B until disconnected from the lower pipe, as seen in dotted lilies in Fig. 2, when it may be turned around out of the way of the lower pipe C, then slipped down and oft from the upper pipe.

As a modification of the construction just described,the trap may be provided with a glass pipe or tube at eachend. For this purpose I provide a short glass tube or pipe, J, similar to the tube H, being provided with a like collanj. In this construction this tube J is inserted and secured in the upper end or neck of the trap body, the same as already described for the tube H and in this modification the Lipper metallic pipe B is shortened and is connected at its lower end to the upper end oi" the glass tube J, instead of ruiming directly into the trap.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l, In a refrigerator an upper drip-pipe leading from the ice receptacle, in combination with a separate lower pipe C leading out from the refrigerator, and an independent cast glass trap, adapted to connect the said pipes and detachable at will therefrom Without removing either of the`pipes, substantially as described.

2. In a refrigerator, the trap D cast in glass and provided with the threaded necks d, d', in combination with the perforated screw caps E and F, the glass tube H secured in the lower neck ot' the trap by the cap F, the rubber gasket G secured on the upper neck by the cap E, and the drip pipe fitting closely said gasket, substantially as described.

3. In a refrigerator, the glass trap D provided with threaded necks d, d,in combination with the screw caps E and F, the wide rubber gasket G, the drip pipe B closely itting said gasket, the glass tube H provided with [iange h, whereby it is secured in the neck d by the cap F, and the lower or outlet pipe C fitting upon the projecting,r end of the tube H, substantially as described.
