To all whom it may concern;

Be it known that I, HARRISON M. TURNER, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Car-Cleaning Apparatus; and I do declare the following to e a full, clear, and exact dGSGIlPtlOIl of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part .of this specification.

This invention presents an apparatus operative to direct a stream or streams of.fluid or .fluids against the exterior of a railway or purpose of cleansing the other car for the same between trips, or for cooling the same in summer, and by the use of which the employment of the hand labor now used in the cleansin of the exteriors of railway cars may be avoi ed and the operating expenses of y reduced.

Among the objects ofthe present invention are, first, to provide a cleansing or coolof railway cars etc., the operation of which will be automatically-controlled by the cars to be cleansed or cooled: second, to provide means by which the closing of the valve which controls the supply of water to the discharge pipes will be to provide automatically retarded; third, means which will efiectually cleanse and cool the ends as well as the sides. of railway cars: fourth, to provide means for cleansing the exteriors of railway cars which will render unnecessary the use of brushes and will thereby obviatethe marrin of the aint due to the employment of brus es: fift to provide, for washing or cooling the exteriors of railway cars, an apparatushaving means :by which the sizes of the outlet openings may be adjusted whenever desirable or necessary: sixth, to provide an apparatus for washing or cooling railway cars which wiIl-beadapted to be operated automatically by a car to be cleansed or cooled and is also-adapted to be unaffected by a passing car: seventh, to rovide an ap aratus for cleansing-and coofing cars' whichlmay be adjusted at'will to be operated automa'ticall by a car approaching from one direction 0 y, or by a the direction of proach thereof, or to be ing car.

To these several ends the invention, as hereinafter fully set forth and definitely pointed out in the subjoined claims consists, essentially, first, in the combination with means throu h which a stream or streams of fluid may e su plied to the surface to be cleansed or cooled trolled by the car to be washed or cooled for automatlcally controllin the supply of fluid to said surface: secomi in the combinat1on ,w1thfluid-supply means, a valve controlhng the supp 1y thereof and a device actuated by a passing car to open the valve when the car a proaches the ap aratus and to hold the va ve open while t e car is in osition to be cleansed or cooled, of means or automatically closing said valve when the car has passed out of engagement with said device, said closing means being such that the closure may be effected at a speed which will render it unnecessary to reopen the vvalve for each car of the assing train being Washed or cooled: third in a novel arrangement of water exits by which they are caused to direct their streams'respectively forward and rearward slantingly toward the car: fourth, (a) in a novel construction of water exits by which the water is directed forcibly against the side of a car in a solid sheet reaching a proximately from the top to the bottom 0 (b) in the combination with means for forcibly directing a stream or streams of water against the side of a railway car to be cleansed, of means by which a stream or streams of air may be directed against said side to blow the dust etc., therefrom in advance of the supply of water thereto: fifth, in a dischar e p1 e for car-cleansing apparatus forme wit openin and having means 0 erative to draw and ho d the side walls of sai opening nearer to or further from each other to thereby adjust the Width of. said opening: sixth, in the combination with wateraconducting means of car cleansing apparatus, including a valve operative to permit or cut-off the passage of water, of an' 'adjustably-supported device connected with said valve to operate the apa passsame, said device being adapted to be adof pivoted means conthe wall thereof;

justed into the path of a assing car to be operated thereby or out 0 the path of said car so as to be unaffected thereby: seventh, in the combination with water-conducting means of car-cleansing apparatus, including a valve operative to permit or cut off the passage of water, of a evice mounted to be adjustable into the ath of a passing car so as to be automatica ly operated to open the valve, and to be adjusted and held out of said path when it is not desired to operate it automatically, and means for locking it when desired against being forced into the latter position by the engagement with it of a car traveling in the direction in which it moves to said latter position.

The invention also consists in certain further novel combinations of Iparts embodied therein: and in novel detai s entering into and constituting the preferred construction thereof, substantially as hereinafter described and particularly pointed out in the subjoined claims.

Fig. 11 is a view showing a different construction of means for slowly bleeding the piston chamber of the valveretarding means, and Fig. 12 is a detail view of a portion of one of the discharge pipes, clearly showing its construction by which the diameter of its discharge opening may be adjusted.

In the present invention the cars are cleaned by means which are respectively, adapted to remove the loose dust and adherent dirt from the surface of the car. These means, as herein embodied, constitute dusting and washing instrumentali'ti'es which are arranged 1n operative succession, in the order namer along the length of the car. Thus, in the cleansing of the car, the loose dust is re moved from the surface immediately prior to the washing thereof. The dusting instrumentality may in the broader aspects of the invention be of any suitable character but it preferably contemplates the use 0 compressed a1r, or other d fluid under pressure, adapted to blow the dust from the surface without marring the latter. The washing .instrumentality obviously contem lates the use of water, or other suitable was ling fluid, and it is preferred so to construct the same as to avoid the necessity of the use of brushes in the washing operation.

The operation of the dusting and washing instrumentalities is effected by a common actuating means which, as herein embodied, is operated by or under the control of the car to be cleansed. This actuatin means has a pivoted lever 19 which is provi ed at one end with a head 9 which projects into the path of the car to be cleansed and is enga ed and pushed back by the latter to turn t 1e lever pivotally, and said lever is so connected with the valve 6 of the washing instrumentality as to move the same from its seat when the lever is thus turned. When the dusting instrumentality discharges adusting fluid, it is provided with a valve 40 similarly having suitable means by which it is moved from its seat when the lever is turned pivotally by the car to be cleansed. The head on the lever is preferably rotatable, whereby its liability to scratch the surface of the car is reduced to a minimum.

Moreover, when the dusting instrumentality employs a rotative brush, such a head has an additional function, for it-then becomes practicable to utilize it to communicate motion I directly to said brush, as hereinafter clearly set forth.

Havin thus in a general way set forth some of t e important features of the invention, I will proceed more fully to describe the construction and operation of the same, as follows The same numerals of reference designate the same parts in the several fi ures.

A pipe or pipes 1 constructed and arranged to direct the stream of cleansing and coolm fluid against the exterior of a car is employe in the system. The purpose of this invention will best be subserved by the employment .of a series or battery of said pipes 1 at each side of a track alon which asses the car to be cleansed or coo ed, so tiiat a plurality of streams of the fluid will be directed simultaneously against each side of the car. It is also greatly preferred that the outlets from the plpes be arranged to cause the fluid to issue therefrom in a direction inclined to the length of the car to be washed, and with one /portion of each series slanting forward I. and the other rearward toward the car, whereteries of pipes is so fering with each other between the cars. directing the streams aslant to the surface to were directed against the same in a'direction at right angles therewith.

same from to both them in any suitable way,

' is greatly preferre 'by a common valve and valveactuating source of supply through the pipe 4. The battery of discharge ipes on oneside of the -standpipe, while the battery 0 pipes on the -other side may rise from corresponding by the ends as well as the sides of the car will be reached by the cleansin and cooling fluid, as clearly indicated by t e dotted lines in Fig. 3. The distance between the two batadjusted as topreventthe streams of fluid issuing therefrom from inter-- be washed thereby the latter is more effectually cleansed than it would be if the streams A most 1m ortant advantage will) be gained by emp oying as the outlet of each pipe 1, a continuous slot 2 extending longitudinally of the ipe and. approximately as long asv the heig t of the car-body to be cleansed, whereby the stream will issue in acontinuous sheet (instead of in 'a-series of jets) which bears such relation to said body asforcibly to strike every portion of the top to bottom equally. This construction makes it practical to rely upon. water under pressure as the principal or sole means of cleansing the car and dispenses with the necessity of the use of brus es as the principal cleansing means.

' It is within the scope of the invention 'to employ a pipe or system of ipes on one side only of the track or car-:an to supply it :or and when a pipe or series of pipes are employed on each side of the car 'or track they may be supplied independently of each other, be of the same' or different construction and have the same or different valve-o crating means. But it d as above indicated to employ a system of pipes at each side of the car or track, supply 0th from a means com mon thereto and control the supply for both means.

A suitable water supplying means includes a standpipe 3 connected 'with a suitable car or track preferab y depend from branch pipes 11 connected with the up er end of the branch pipes 11 which are connected, for exam 1e by the pipe 5 extending beneath the road hed, with. the lower end of said standpipe. Arranged in the standpipe 3, below the junction of the pipe 5 therewith, there is a valve 6 which controls the supply 011 water batteries of discharge pipes. This valve 6 is provided with a stem 7 and isrnoved to and from its seat 8 by a means the operation of which is controlled automaticall by the passing car to be cleansed or coole and has one of its Any means for this purpose which is so connected with the valve or its stem as to operate the same and which is arranged to be --.i

operated automatically by a passing car to be cleansed or cooled, tl'ieinvention; The meansreferred for "the purpose includes a roller, which is well adapted to serve the function with'a minimum of friction, arran ed to be. operated by the body: of the-car." v V vided for automatically returning the valve;

'u'itable means are also pro- 61 and its operating mechanism to their origivnal. positions, upon the passing of the car or train,'so as to automatically shutoif the discharge of water and leave theparts in position to be operated" by another train to be cleansed. or cooled.- 1

Two different constructions of valve-operating means (the. differences being in the connectlons between the head and valve-stem) are shown in the accompanyin drawings, as examples. "One form, in whic the head is designated b the numeral 9, is desi edfor use in situations where there is amp e space to ermit the stand ipe,3 to be arranged su ciently distant cm the batteries o1 pipes l on its sideof the car to enable a lateral connecting pipe 10'to be emplo ed between said stan pipe and the branc pi cs 11. In this construction a bodily-move le rod 12 is lowered to de ress the valve 6 from its seat, said rod suitably stem 7 and being supported an connected with the head 9 so as to have said bodily movement imparted to it in one direction when said head is struck by a passing car.

A most suitable means for connecting it'with said stem consists of a slot 13 formed longitudinallyin it and receiving a pin-14 projecting laterally from said stem, whereby when said rod 12 is lowered in :the arc of a circle it will move relatively to and depress said valve stem. Preferabl there are two of these rods 12 employe one at each side of the upper end of said stem, whereby tendency to wobbling or lateral movement of the stem .and diversion of the valve 6 from a straight line in its movements is avoided. A most suitable means for operating said rods 12 includes leveds 15 the upper ends of which are connected by said rods (which are pivoted thereto as shownat 16) land the lower ends of which are pivoted between lips or flanges 17 which pro ect from clamping members 18 suitably secured to the upper end of the standplpe. The motion which 0 erates the rods 121s communicated to one of said levers 15 and the two levers (15) combine with each other and with said rods 12 to ive the latter rods their proper movement. or transmitting motion from the head 9 to the lever 15 a most suitable means embraces a :lever 19 which is fulcrumed'at 20 between its ends ends connected with said lever 15 by a link 21 while its other end carries said head 9-. This lever is shown as arranged above one of the branch pipes 11 and as extending from beyond the free end of the is Within the scope of engaging the valve- &

latter to the connecting pipe 10, and the link 21 extends over said connecting pipe to the lever 15 from a projection 22 wluch rises from said lever.

The operation of the parts thus far described is as follows: Normally, the valve 6 is on its seat 8, its stem is elevated, the levers 15 are. approximately vertical, the rods 12 are in their highest position, the head 9 is located over the plane of the tracks or in position to be operated by a car and the lever 19 and link 21 occupy their corresponding positions. The first car of a train, approac ring the cleansing means in the direction of-the arrow (1, Fig. 3, strikes the head 9 and moves it bodily outward, thus causing the lever 19 to turn on its pivot 20, in the d1rection of the arrow 1), to the position shown in full lines in Fig. 3, thereby depressing the valve and causing the car to be washed by the water issuing in sheets from thepipes 1. To return the several parts automatically to their original positions, a weight '23, suitably connect ed with the lever 19 by means of a cord or chain 24 and pulley, 25, may be employed.

With the construction thus far described the supply to the discharge pipes will be closed immediately a car passes out of engagement with the head 9, and when a train of cars is to be washed or cooled must be opened by each car thereof. To obviate this, any suitable means are provided by which the valve is closed slowly upon the passing of a car out of enga ement with the head. The means preferred embrace a water chamber 26, located in the upper end of the standpipe 3 and divided from the main chamber in said ipe by a floor or diaphragm 27, said cham er 26 having provision for slow bleeding. A space may be provided around the stem 7 and in the floor 27, through which said chamber 26 has communication with the standpi e, and the ortion of said chamber above t e piston 28 ms communication with the portion thereof below the iston through spaces which may be provide for said purpose between the erimeter of the piston and the wall of said ciamber. Thus, when the valve 6 is open water will flow from the standpipe into the chamber 26 and above the piston, and as the piston ascends the water above the same Wlll slowly return to the stand ipe. In Fig. 11 a different means for t e same purpose is shown, wherein the piston 28* has a flap valve 29* which will ermit water to flow into the ortion of the dhamber above said piston, am said ortion has a cook or valve 30* through w iich the water is slowly forced by the u ward movement of the piston. By either 0 these means the raising of the valve 6 to its seat is resisted by the pressure of the water above said piston and the closing of the valve is materially retarded. The operation of the returning means preferably is such that with the next car of the train.

to press upon and lower the valve stem.

there is little ap reciable closing movement, if any, of the va ve. during the time between the disengagement of one car of a train from the head 9 and the engagement of said head Thus, the valve will be held 0 on until after the entire train has passed, w iich fact, together with the aforementioned aslant arrangement of the discharge openings, assures that the entire train, including the ends of the cars shall be effectually washed. This means also avoids liability of damage to the pipes which may occur from back pressure when the valve is closed suddenly.

In the modilied construction, shown in Figs. 8 and 9, the branch pipes, designated 11 which carry the discharge pipes 1 are connected directly with the standpipe 3", the pipes 10 of the other construction being dispensed with, and said discharge pipes )1'0- ject upward from said branch pipes. The connecting-means between the valve stem 7 and the head 9 is changed to suit the changed arrangement of pipes. Said head 9 iscarried by one end of a lever 19" the fulcrum 20 of which is at its other end. Between its fulcrum 20 and ower end (which latter is bent upward as s iown at 22) this lever is provided with a link 21 which connects it with one arm 15 of a bell-crank lever, the other arm 12 of which bell-crank lever engages the upper end of the valvestem 7 or a Thus,

rojectlon therefrom. when a car strili'es the perimeter of the head 9 and pushes the same back in the direction of the arrow it corres ondingly forces back the lever 19, which tlicreby pulls upon the link 21 and arm 15 and causes the arm 12 A spring 23 encircling the upper end of said valve stem operates automatically to return the parts to their original positions.

To give elasticity to the parts and afford maximum facility for the flushing of the pipes to remove sediment and dirt thererom, one end of each discharge pipe is left free and is normally closed by a cap 30 removably applied thereto. Suitable transverse slots 31 are formed in each discharge pipe or the pipe is otherwise so constructed as to be expansible and contractiblc as to its diameter, and applied around each pipe is a clamp 32 or other suitable means operative to contract the diameter of said pipe or to ermit the same to ex and, whereby the width of the discharge s ot 2 therein is adjustable. I

A useful adjunct to water in the efl'ective cleansing of the car, comprises means for removing the loose dust and dirt in advance of the application of the water to said car. Any means for this urpose is considered to be within the purview of broadest claims hereinafter presented which include dustremoving means broadly as an element.

Two means are shown in one of whieh (see Fig. 10) a dusting brush 38 is mounted to rotate adjacent rotated by frictional contact with the latter when the latter is rotated by its engagement with the car. The preferred means, 'however, contemplates the use of airor other dry fluid under pressure ex elled against the side of the car body and bi or dirt therefrom. Preferably the discharge pipes 35 for the com ressed air are similar to those hereinabove escribed fovthe water, and they preferably are connected with the same branch ipes 11 or 1.1 through which said water-( ischarge pipes are su plied. When said preferred construction 18 employed, a wal or plug suitable place in the branch pipe to divide it into two chambers having no communication with each other, one 37 (Fig. 7) for the water supplied to said water-discharge pipes -1 and the other, 38, for the air supplied to the air-discharge pi es 35. The plug or wall 36 may be mounte to be adjustable within the branch pipe so as to cut oil the water at any point to give the desired number of air papes in the system. In Fig. 7 it is shown as a j usted to cause the air to be discharged through two ipes at the end of the branch ipe 11. In ig. 2 it is indicated as adjusted or the use of only one air-pipe at the end of said branch pipe. An ordinary air nipple 39, mountedon said pipe 11 and connected with a suitable source of air under pressure (not shown) may be employed to supply air to said chamber 38 and iseharge pipe or pipes 35. It .will be advisable to cutofl the supply of air to said chamber 38 at the same time that the su ply of water to the chamber 37 is cut off by t e closing of the valve 6 and to open thesupply to the chamber 38 when the water is turned on. Any suitable means for the pur ose is within the scope of the invention. example of means which may be employed is shown in the drawin s, said means consisting of an air-valve 40 ocated adjacent to the nipple 39 and provided with a spring 41 for pressing it to its seat, said valve being moved from its seat automatically by the en ragement' with its stem 42 of a wedge-shaped block 43 which is carried by the lever 19, so that when said lever is moved to open the water supply valve 6 it will carry said block with it and simultaneously open the air-supply valve, and when said lever is moved to close said water suppl valve the narrower portion of the block wi 1 be brought opposite the stem 42 of the airsupply valve and the spring of the latter will be permitted to force said air-supply valve to its seat.

It may sometimes be desirable to'render the device tem orarily inoperative by a passin car, which lspreferably accomplished by a justing the head?) out of the path of said to the rotative head 9 and is owing the loose dust ally movable bolt 47 attach an operating 36 may be located at a car. To this end said head is pivoted on one end of a lever '44 the other end of which is pivoted, at 45, to the free end of an arm 46 pIrojeeting from the free end of the lever 19.

ormally the lever 44 underlies the arm 46 throughout its length, but it can be adusted upon its pivot 45 to thereby carry the head out of the path of a passing car, as shown in dotted lines in Fig. 3. To look it in the latter position there ma be employed an axiiaving its ends bent in dili'erent directions one, 48 to engage a perforation 49'in said head and the other, 50, to cord 51 to. Aweight 52 will serve automatically to turn the bolt axially to its normal position when disengaged from said head, and a spring 53 will automatically return and hold said lever 44 and head in theirsaid' normal, positions. Obvious! with the construction thus far deseriber a car a preachingthedevice from the direction of tile arrow 0, when-the parts are in their positions with-the head in the path of said car, will press upon said head and turn it with its lever 44 outward on the pivot 45, relatively to the lever 19, without moving the latter and hence without opening the valve 6. T-hus.said ear or cooled. But if it is to wash or cool cars approaching from either direction, the same may be accomplished by adjusting the bolt-end 48 downward across the path of the lever 44, thus lockin the parts together so that the lever 19 wil partake of the outward movement of the head when the latter is struck by a passing ear appreaching in the direction of the arrow -c as we'll as to partake of the outward movement of the head when the latter is struck by a car approaching from the direction of the .arrow a. 1
