Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed July 22, 1914. Serial No. 852,500.

Be it knownthat I, JOSEPH N. SUPRU- NowsKI, a citizenofthe United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Car Attachments, of which the following is a specification.

This invention relates to improvements in the air line equipment of cars.

The leading feature of .my invention consists in providing a means combining the cut-off valve feature and dust collecting feature which concerns the air line mechanism with which railway cars are equipped.

"The general practice invogue todayfis uch" the air pump engine, and for collectingthe dust that may accompany the airthrough' the various air pipes with which the car is provided. 7

-One.of the important objects of'my invention consists in providing a simple, inexpensive, and highly efiicient combined cutolf valve and dust collector for air line systems of cars which is characterized by simplicity of construction whereby the expense of providing more than one connection for the accomplishment of these functions is obviated and whereby the hazard of freez ing the dust collecting apparatus which is today felt is overcome.

A further obJect of my invention lies inthe provision of a single casting so con structed' that the air which is forced through the air pipe of the car is utilized for the purposenof discharging the dust, moisture, and all"'foreign particles with which the air may be laden'from the pipe line and at, the same time to provide for draining the casting of any such accumulations of foreign particles. Y

The present practice of removing the dust from air pipes consists in removing screw plugs from one or more points along the length of the pipe and this operation is only done when the car shall have been removed on a repair track andthisrequires considerable time and expenseto assure that v the air pipes are in good order and working condition. It has been found that the moisture present in the air pipes even if col- 'lected in the present types of union and similar pipe connections results in the freezing" device and cut-off valve in an air line system and to locate a single connection 'at a polnt where the same may be more readily accessible for the purpose pf inspection and repairs than has hitherto been found to be thebase as well as to e'lficiently provide for discharging the dust and draining the moisture that may be present. in the air pipes of said system.

With the above andother objects in view my invention consists in the combination, arrangement, and details of construction disclosed in the specification and accompanyingdrawings, and then more particu larly' pOmted-out in the appended claims.

In the drawings, wherein similar reference characters designate similar parts throughout the respective views, Figure l is a side elevation of my invention showing it mounted in proper position upon an air line of pipe. my invention, Fig. 3. is a detailed View of a deflector to be described, Fig. 4 is a sectional view of-a cleaning valve and accessories to be described, Fig. 5. is a sectional view of a modified form of my invention, and "F ig. 6 is asectional view of the defiector mechanism of my modified invention.

Referring to' the drawings which. are

.the inlet pipe 2, the plug being provided with a port 7 with which is adapted to register the port 8 formed in the plug seat 6. The internal configuration of the union will be irregular so that metal will be massed at such points as will be effective to provide a passage 9 leading immediately from the 'inlet pipe 2, an admission passage 10 of a diameter less than one-half the diameter of the inlet or outlet port leading downwardly from the passage 9 and an upwardly extending discharging passage 11 a diameter Fig. 2 1s a sectional view-of inlet or'outlet port communicating with the outlet pipe 3. By this construction it-will.

be seen that a circuitous course and passage 5 is proyided for the air'in passing from the inlet into the outlet pipes.

12 denotes a suitable deflector which in this instance is shown in the form of a concavo-convex hood the same being sustained in position directly underneath the passage 10 by such means as upright stems 13, the latter being provided so as to provide clearance spaces for the passage of the collectings deposited by the air passing 1 through the said passages out of the outlet pipe 2. Aspecial mounting and connection is pro videidizwhich is adapted to be removably secured'to the pipe union 1 and which carries or inay carry the deflector 12. This mounting is virtually a valve casing 15 having a threaded nipple 14 threaded into the pipe union and this, valve casing has a bore 16 extending from end to end thereof. Formed to receive the conical plug 18. It will be seen that the conical valve seat '17 corn-v miinicates with an annular chamber 17. The conical plug 18 is provided with a spring socket 19 into which projects one end of a coiled spring 20 the opposite end being snugly received in the spring cap 21 I which is threaded into the annular chamber 17', a nut 22'being integrally formed upon said cap whereby the samefmay be readily removed. The spring 20, it will be understood, will beput underitension so as to cause the conical plug 18 to lie' snugly in its seat. The plug 18 is provided with a transverse opening 23 which, when the plug shall have been rotated a satisfactory distance, will register with the bore 16 formed in the valve casing 15. An operating handle- 5 24: serves to rotate the valve plug to bring its port or opening into registration with the bore 16 so as to provide a clear passage for the escape of dustand drainage. 24' denotes a nipple formed upon any part of the air pipe line and the outlet pipe 3 of applicants union 1 will bethreaded v upon said nipple thereby establishing intercommunication between the union and said airline at onev point and by means of suitable pipe connections engaging the inlet end of the union 1 which latter will be properly mounted position. It is contemplated that the\union 1 should be so located as to make it easy for the same to beinspected and cleaned if desired.

Rust scale and dirt collects in the dust collector which applicant provides and which is formed at the lower end of the union in the space surrounding the stems of 5 the deflector, and through the use of the plug or valve 18 it will be possible for any in the casing 15 is a conical seat 17 adapted portant featurev of draining the air line cannot be overlooked as water accumulates from moisture in the air pumpedinto the train line and then collects in the bottom of the dust collector. and would ordinarily freeze causing the pipes to burstthereby causing a grea-tamount of delay to the cars in transit. By means of applic'ants valve 18 the bottom of the dust collector can'be opened at any time so that'no dust can accumulate which cannot be readily expelled. B y-opening this valve the car charged with air will serve the useful purpose of enabling this air to expel the foreign particles. -The air entering through the inlet pipe, 2 will pass downwardly through the admission passage 10 when itsv path will be broken thereby affordingv an opportunity for any dust or moisture to-settle upon the deflector whence the same will be diverted into the dust collector and will remain there as long as the port or opening 23 formed in the conical In 18 is out of registration with the bore 16 formed in the valve casing 15. The air being thus rid of its foreign particles andhaving its course diverted will pass upoutlet pipe 3 to continue its flow to the point where desired. Of course the handle 5 con-' trolling the operation of plug t may be manipulated to cut off thesupply of air as may be desired. When the opening 23 is in registration with the bore 16 and air is'passing through the union l the same will expel the dust or moisture through the bore 16 so vwardly through the passage 11 out of the hitherto described except as concerns the 1 construction of the drain valve which will now beset, forth. The deflector 25 is ofthe same shape as the deflector 12 already described and it is supported upon a stem -26 which is connected to a plug 27 arranged to close a plug seat 28 formed upon a tube 29 removably connected to the union and 30 -is a spider supported in said tube 29 through which passes the rod or stem 26. A spring 31 is coiled around the rod 26 and bears at oneend against the spider and rests at its opposite end upon the oppositely disposed levers 32 which are suitably fulcrumed upon pivots 33 provided in the clearing spaces in the tube 29, said levers being disposed obliq'uely with respect to said stem and being operated by means of such flexible elements as cords 34. The cords 3 L will lead to any desirable point along the air line and when saidcords are pulled the levers will be forced upwardly thereby putting the H spring- 31 under'tension 'unseatin-g theplug which is free to move with the stem 26 thereby enabling the air under pressure to expel the dirt or moisture from the union out of the bore 35 formed in the tube 29.

ditions where it is desired to actuate the valve controlling the discharge of the dust from some distant point.

Numerous modifications may be resortedv to in practice without departing in principle from the details of construction herein disclosed.-

What I desire to claim and secure by Letters Patent is l. A dust and water trap for fluid pressure lines, comprising a T-shaped coupling having formed therein an air inlet port, an air outlet port, and a circuitous passage of a diameter less than one-half of said-inlet and outlet ports connecting said inlet and outlet ports and having its intermediate portions enlarged to form an expansion chamber, a concavo-convex deflector in said chamber, and means journaled in the walls of said coupling for establishing communication between said expansion chamber and i the atmosphere.

2. A dust and water. trap. for fluid pressure lines comprising a T-shaped coupling having formed therein an air inlet port, an air outlet port, an expansion chamber, an air admission passage establishing communication between said air inlet port, and said chamber, and a discharge passage establishmgcommunication between said outlet port and said chamber, a deflector having a convex upper surface in said chamber, the access of said admission and discharge passages intersecting at the upper surface of said deflector, and means ournaled in the walls of saidcoupling for establishingcommu'nication between said expansion chamber and the atmosphere, said means comprising a plug rigidly connected to said deflector, a casing threaded into said coupling, said casing having a valve seat to receive said plug,

a coil spring for seating said plug and levers swingingly mounted on said casing and pivotally connected to said plug whereby the latter can'be unseated against the tension of said spring.
