TRAP AND DRAIN.

Application filed February 27, 1924. Serial No. 695,409. i

To all who/m, t may concern.'

Be it known that I, Lo'rHAn voN DAB- nowsKI, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Traps and Drains, of which the following is a specification.

My invention has reference more particularly to a combined trap and drain of the type used in refrigerator cars.

The cooling of refrigerator cars is effected by the use of ice and salt, and it is customary to provide trapped outlets at suitable points leading through the floor of the car, to drain off the water resulting from the melting of the ice. Inasmuch as the outlet pipes vary in length according to the construction of the car, the type of drains now in use, which require a special construction of the outlet or drain pipe, are objectionable on account of the expensey and also because such traps and pipes have to be specially made for each installation. With my invention, however, this objection is avoided, as my construction does not require a special form of pipe but uses an ordinary pipe which is merely cut to length and then threaded or drilled for rivets at the ends.

The principal objects of my invention are to :facilitate the equipping of refrigerator cars with trap and drain pipes; to avoid the necessity of special patterns to make the traps and drain pipes; to construct the device so that a plain length of pipe may be employed by merely cutting the pipe to the `required length and threading or drilling rivet holes at the ends; to provide an improved arrangement for mountinga trap cover and a spout on the ends of the pipe; to improve the connectiony of the pipe with the bowl; and in general, to provide a simple, inexpensive and easily constructed drain andtrap structure for refrigerator cars.

On the drawings: f

Fig. 1 is a sectional view of my improved drain and trap, and a fragmentary portion ofy a refrigerator car to which it is applied;

Fig. 2 a sectional View of a `modified form `of my drain ,and trap l;

Fig. o a sectional view on the line 3-3 of Fig. 2;

Fig. 4 a vertical sectional view of a modied form of spout connection;

Fig. 5 a sectional view on the line 5-5 of Fig. l; and

Fig. 6 a sectional view showing the bowl and pipe before assembling.

Referring to the drawings, the reference numerals l and 2 indicate respectively the inner and outer sheeting of an insulated wall of a refrigerator car, the reference numeral 3 indicating heat insulating material which is interposed between the inner and outer sheeting. A bowl-shaped member 4, preferably of drawn metal, is set into the 'bottom wall or Hoor of the car as shown, said bowl being provided with an annular flange 5 which is mortised into the inner sheeting 1 as shown, and-secured in place to a lining 7 by the rivets 6. The lining 7 of the car extends over the flange 5 and has the inner edge turned down as indicated at S to drainv into the bowl.

The bowl 4 is formed with an opening in 75 the bottom surrounded by an upturned flange 9, and a drain pipe l() projects up through the outer sheeting 2 and through the opening in the bottom of the bowl 4 as shown, said opening being of such size that the pipe 10 has a driving fit with the flange 9, whereby the pipe is securely held in place. The pipe may also be additionally secured in place by being spot-welded in two or three places at the top of flange 9.

In previous structures it has been customary to turn the flange 9 downwardly and this forms a crevice between the pipe and the bowl 4in which sediment collects, particularly salt, which is carried olf with the 90 water, and this accumulation of sediment tends to rust or eat away the adjoining metal as the same can not be easily removed. lith my construction the turning up lof the flange 9 forms a rounded corner at the junc- 95 ture of said flange with the body of the bowl 4, and prevents any such accumulation of sediment as the same cannot be easily removed. Moreover, I prefer to galvanize the parts after they are assembled, and this serves to fill in the offset or shoulder at the top of the Ylange 9 and also unites the pipe and bowl more securely.

A collar 11 is secured to the upper end of the pipe l0, and has a number of lugs 12 arranged at intervals therearound and projecting up above the upper cud et the pipe 1() to support a cap 13, and a'tiord outlets 1l between the lugs 1Q, through which the water overflows from the bowl t into the pipe 10. This cap 18 has an annular flange. extending downwardly below the open-- ings 14e so that the level of the water in the bowl l is above the lower edge of the flange 15 and forms a water seal for the drainage out-let. This cap 13 is preferably hinged so that it may be turned back away from the top of the pipe 10, and to this end said cover is formed at one side with a hinge extension 16 embracing a laterally extending hinge lug 17 of the collar 11 to which the cover is pivoted by a pin 18, which is preferably in the forni of a cotter pin.

The collar 11 may be secured ou the pipe 10'in any convenient manner, as for example, by an ordinary threaded connection as indicated at 19 in Fig. 1, or by rivets placed at intervals around the collar 1l as indicated at 2() in Fig. 2.

For attaching a spout to the lower end of the pipe 1U, a collar is likewise secured onto the lower end ol the pipe by a. threaded connection as indicated at 21` in Fig. 1, or by rivets as indicated at Q2 in YFigs. 2 and l. This spent, which is preferably et sheet metal, may he hinged directly te the collar as shown iu Figs. 1 and 2, or may be hinged to the lower end of a downwardly extending section which is fixed onto the collar as shown in Fig. t. lVhen this spout is hinged ente the collar, the latter is formed as shown at with a pair of hinge lugs Q4 at one side between which the upper end ot the hinge strap en the spout is pivoted on the pin Q6, which is preferably in the form of a cotter pin. The spout in such case is formed with a depending section 27 with an inclined section 28 secured to the lower end, and the upper end of the section 27 has a rolled edge Q9 which is held by the weight oi the laterally extending section 28 against a liange 30 ou the collar 23.

ln the spout construction shown in Fig. 4, the laterally extending spout section 31 is hinged at 3Q to the upright spout section 33, and the latter has the upper end expanded to form a

shoulder

9,4 which iits against an annul-ar flange en the collar 36, and the up per edge of the spout section 33 is turnedv over the flange 35 as indicated at 37 to lock the spent onto the collar.

lllhile I have shown and described my invention in a preferred form, I am aware that various changes and modifications may be made without departing from the principles otl my invention, the scope of which is to be determined by the appended claims.
