DRAIN TRAP.
Application led January 6, 1926.
My invention relates to a drain trap which is particularly suitable for installation upon railway refrigerator cars.
It is the object of my invention to lprovide a device of this class which 1s simplein construction, which can be economically manufactured and which has improved means for` Fig. 3is avertical sectional view showing a modified embodiment of my invention, an-d Fig. 4L shows Ithe-rod used in raising and rotating the cap in the yembodiment shown in Fig. 3.
Similar characters of reference refer to similar parts throughout the several views.
Referring toFigs. 1 and 2, I have shown the drain trap set in the floor 10 of a railway refrigerator car, 11 being `the drain pan which is usually employed in bulli heads of such cars. The car construction, so far as illustrated in the drawings, is conventional and need not be described in detail. The idrain :pan 11 is provided with la circular opening 12 around the periphery of which the receptacle or bowl 13 is securely riveted. The bowl 13 is preferably surrounded by heat insulatingmaterial 14. A pipe 15V is centrally fixed in the bowl 13 and preferably extends upwardly into the bowl through its bottom to a little more than half of the height of the bowl. A ring 16 fits loosely around the pipe 15 at the bottom of the bowl and serves as a bearing for a rotatable collar 17 to which one leaf 18a of a hinge 18 is riveted. The cap 19 is riveted to the other leaf 18b of the hinge 18, the leaves being connected by the pintle 18". The cap is thus mounted for rotating and pivotal motion. Suitable means, such as rivets 20, are pro vided to prevent upward movement of the collar 17. A stop 21, riveted to the pi e 15, serves as a support for the cap in its ower Serial No. 79,617.
position. A strainer plate 22, provided with a plurality of small perforations 22a and larger perforations 22h, is formed in two sections which are joined by the hinge '23 which has a pintle 231l which lies parallel to the pintle 18". the top of the cap 19 extends through a spacer 24h and is riveted to the larger section ofthe strainer plate. rlhe portion 2li2L of the rivet 241 inside the ca p 19,i`s eye shaped and is threaded by a cooperating :eye25iL of 'the agitating and rotating rod`25. Rod'25 freely extends through an `elbow '26, which is riveted to the llower end of the pipe 15, at a boss 26l which ,projects inwardly *from the pipe so as tol prevent water fromlealting out along side the rod25. The tlow-er end ofthe rod Y25 .is bent at right anglesto form ahan die 25b by which the cap may be raised and rotated. A sheet steelspout2' maybe secured to the lower portion of .the elbow L26 by ears 27 which extend through and are bent over slotted lugs 26h, so as `todeflect water and other refusedraining 'from the refrigerator car away from journal boxes of the car.
In Fig. 3 Ihave shown a ymodification which in most respectsV is similar to that shown in Figs. 1 and2, with the exception that in this showing the agitating rod is not secured in the device but in use. is carried from car to 'car by the workman lwho is cleaning the drains of lthe cars. v"In F 3 the rivet 24 by which the straining plate and the cap aresecured together terminates in an eye 24a( preferably 2of much ,greater diameter than that shown in Fig. 2 soy aste readily permit the entrance ofthe hook portion. 28a of therai'singand agitating rod 2 8.
In this embodiment the elbow 29 'hasa pro- .jecting lug V29n which is hingedly connected vto corresponding lugs 30a 'formed on an extension 30 which is riveted to the pipe 15. The lower edge of this extension is preferably cut off at an oblique plane and the el bow 29 has an annular recess formed in its upper edge so as to fit over the lower edge of the pipe extension 30. A chute 27 is secured to the lower end of the elbow 29 for the purposes as already described. The elbow 29 is retained in its position as shown in Fig. 3 by the action of gravity upon the chute. It, however, may readil be tilted upward as shown in the dotted line position in Fiff.
An eye rivet 211 secured in* lOl) ' 3 so as to permit access to be had to the inby the workmen by merely raising and rotating the agitating rod. The strainer plate being secured to the cap is also agitated and the sawdust and other dbris thus shaken from the perforations and top of the plate. The rotatability of the cap and the plate makes the agitation and cleansing operation very thorough, and minimizes the possibility f fof damage due to a clogged drain trap.
The invention is capable of variation and adaptation in many respects for use in dif- 'vferent embodiments without departure from the principles of the invention. I -do not restrict myself in any unessential particulars but what I claim and desire to secure by v Letters Patent is:
l. In a drain trap, a bowl, a drain pipe, a collar rotatably mounted on said pipe, a drain pipe cap hinged to said collar, and means to rotate said cap and collar.
Y 2. Ina drain trap, a bowl, a drain pipe, a
collar rotatably mounted on said pipe, a drain pipe cap hinged to said collar, and vmeans to rotate said cap and collar and to swing said cap relative to said collar.
3. In a drain trap, a bowl, a drain pipe, a collar rotatably mounted lon said pipe, a drain pipe cap hinged to said collar, and means secured to said cap for rotating said cap and collar.
4. Ina drain trap, a bowl, a drain pipe, a collar rotatably mounted on said pipe, a
Vdrain pipe cap hinged to said collar, and
Ameans secured to said cap for rotating said cap and collar and to swing said cap relative to said collar.
5. In a drain trap, a bowl, a drain pipe extending into said bowl,astrainer plate fitting loosely over said bowl,a collar rotatably mounted on said pipe, a cap hinged to said collar, means to swing and to rotate said cap, and connecting means for causing said strainer plate to swing and rotate with said cap.
6. In a drain trap, a bowl, a drain pipe extending into said bowl, a strainer plate fitting loosely over said bowl, a cap hingedly and rotatably mounted on said pipe, and a connecting means securing said cap to said plate.
't'. In a drain trap, a bowl, a drain pipe extending into said bowl, a collar rotatable on said pipe, a hinge connecting said cap to said collar, a strainer plate fitting over said bowl and formed in two sections joined by a hinge the pintle of which is parallel to the pintle of said first named hinge.
8. In a drain trap, a bowl, a drain pipe leading from Said bowl, a cap rotatably and hingedly mounted on said pipe, and a rod secured to saidl cap and extending through said pipe for swinging and rotating said cap.
9. A trap for refrigerator cars comprising a bowl-shaped receptacle, a drain pipe projecting through the bottom of said receptacle, the upper edge of said pipe terminating short of the upper edge Iof the receptacle, a collar rotatably mounted on said pipe, a cap hinged to said collar so as to lie above the upper end of ysaid pipe, a stop projecting from therupper edge of said pipe so as to limit the downward movement of said cap, and means to rotate and swing said cap relative to said. pipe.
10. A trap for refrigerator cars comprising a bowl-shaped receptacle, a drain pipe projecting through the bottom of said receptacle, the upper edge of said pipe terminating short of the upper edge of the receptacle, .a collar rotatably mounted on said pipe, a cap hinged to said collar so as to lie above the upper end of said pipe, a stop projecting from the upper edge of said pipe so as to limit the downward movement of said cap, a hinged strainer plate resting over the top of said receptacle and rigidly secured to said cap, and means to swing and rotate said cap and strainer plate comprising a rod secured to said cap and extendingv downwardly through said pipe.
In witness whereof, I hereunto subscribe my name this 30th day of December, 1925.
