My invention relates to track cleaners and has particular reference to the removal of snow and ice from railroad and similar exposed tracks, particularly in terminals and 5 yards where large numbers of switches and crossovers are employed.

One of the major difiiculties encountered in railroad operation during the winter months is the removal of snow and ice from the tracks and many switches to be found at terminal and. freight classification yards. It is vital that the switches and other mechanism for controlling traflic at these centers be kept clear and in working order at all times and heretofore this-has been accomplished to some degree by steam-heating the switches. This method of keeping the tracks and switches clear of snow is, however, too expensive to be widely used, with the result that large areas must be kept clear by hand removal of snow a slow, costly and unsatisfactory method.

In order to eliminate the difficulties here tofore encountered and to effect a rapid, thorough and economical cleaning of tracks and allied equipment, such as switches, frogs,

crossovers, switch signal lights, etc., the present invention contemplates the provision of a steam jet cleaner which will, by virtue of a combined blowing and melting action, remove snow, ice and other accumulations of foreign material from the tracks. A further object of the invention is the provision of a cleaner of this nature which may be"readily and quickly installed on or removed from railway rolling stock, such as locomotives, tenders or cars, or which may be installed as a permanent part of the equipment of a car used for cleaning purposes. A still further object of the invention is the provision of an apparatus which is simple and rugged in construction, inexpensive to manufacture and install, and requiring little, if any,.repair or maintenance. Other and more detailed objects of the invention will appear in conjunction with the following detailed description of the invention.

For purposes of illustration, I have shown the invention as applied directly to a locomotive or its tender, and in the drawings, Fig. 1 is a fragmentary elevation of a locomotive and tender with my invention installed on the latter; Fig. 2 is a fragmentary elevation of the forward end of a locomotive with apparatus embodying my invention installed directly on the locomotivefFig. 3 is an enlarged plan view of the blower illustrated in Fig. 2 Figs. 4 and 5 are respectively elevation and .plan views on a larger scale of the blower apparatus illustrated in Fig. 1, parts being omitted for the sake of clearness, and Figs. 6 and 7 are enlarged detail views of one form of nozzle employed.

According to my invention, the primary step in the removal of snow or other material from the tracks to be cleaned consists in the dislodgment of such material from the track surface by the prying action of a plurality of steam jets directed toward the track surface at an angle to the horizontal of such degree that the steam jets are caused to rebound or ricochet and produce a strong lifting action on the loose material lying on the track. The angle at which the jets are directed toward the track surface is dependent upon the character and condition of the latter, but I have found that an angle of inclination of approximately forty-five degrees is satisfactory in the maj d'rity of instances. In this connection it is to be noted that in the removal of snow, and more particularly ice formations, from the tracks, the heat in the steam produces a melting action whiclris sufficient to loosen the adhering material so that the blast action of the steam jets issuingfrom the nozzles is able to lift it from the track.

The set of steam jets used to loosen and lift the material from the track is moved slowly over the area to be cleaned at a level a few inches above the track and in a direction in which the stean'i jets point. In order that the steam jets may penetrate between switch points and other track elements lying substantially parallel to the direction of the track, the jets are pointed in a generally forward direction with the result that the loose 9 material raised from the track is thrown forward in the direction of motion of the jets. To prevent this material from again settlin on the track ahead of the blower, a seoon ary step is performed in the cleaning operation,

which deflects the material raised laterally of the track so that it is finally deposited on either side of the area cleaned. The deflec tion of the material to the side of the track is accomplished by the provision of a set of substantially horizontally positioned nozzles having laterally directed tips and located so that the jets from these nozzles intersect the path of ricochet of the steam blast a short distance above the roadbed and deflect this steam, together with the material carried by it, laterally away from the track. Alternately, the second set of horizontal nozzles may be pointed directly forward to impinge upon a V- shaped deflecting shield, which serves to throw the material raised horizontally and laterally away from the track. In some cases where the. nature of the material permits, the horizontal nozzles may be made considerably smaller than the angularly placed nozzles or even omitted, when the deflecting shield is used, as in some cases the steam blast rising from the tracks and carrying with it the material to be removed, will strike the deflecting shield with suflicient force to be carried therealong and thrown a considerable distance from the tracks without the aid of a second set of nozzles. Obviously, in the interest of steam economy, the horizontal deflecting nozzles should be made as small as is consistent with eliectivecleaning and, if possible, eliminated.

Referring now to Fig. 1, I have shown the form of apparatus employing a double set of nozzles and a deflecting shield as applied to a locomotive tender. In the figure, the locomotive is indicated generally at 1 and the tender at 2. The blower is mounted below the teiTder frame and receives steam through the supply pipe 3 connected by means of any suitable flexible connection with the steam pipe 4 leading from the steam dome 5, or other suitable source of dry steam. The supply of steam from dome 5 is controlled by means of valve 6, having an extended control member 7 located in the cab of the locomotive. As is shown more clearly in Figs. 4 and 5, the blower comprises a header formed by a pair of pipes 8 and 9 connected by means of the T 10 to the inlet pipe 3. The header is mounted transversely across the track a short distance thcreabove by means of suitable brackets 11, which are attached to any convenient portion of the tender frame, preferably ina manner permitting of ready removal. A series of vertically disposed nozzles 12, are mounted in pipes 8 and 9, the nozzles being provided with angularly directed tips (see Figs. 6 and 7) disposed so that they throw the jets forwardly and in line with the track at an angle of about 45 degrees to the horizontal. A sec- 0nd set of horizontally disposed nozzles 13 is mounted in the pipes 8 and 9, these nozzles being preferably flattened to throw a horizontal fan-shaped jet directly forward, although, if desired, a nozzle throwing a cone-shaped 'et may be employed. It will be noted from Fig. 5 that the outer ends of the pipes 8 and 9 are rearwardly bent. This form of con-. struction provides a desirable outward dlvergence of the outer nozzles, but it will be ob vious that, if desired, the pipes may be straight and the individual nozzles turned to the desired angle. It will also be obvious that many variations in the shape and form of the pipes and nozzles may be made while still maintaining the same relative position of the steam jets with respect to the track. Pipes 8 and 9 are closed at their outer ends by caps 14, in which are mounted nozzles 15, having their tips bent so that the jets from them are directed horizontally at right angles to the track.

In front of the blower there is mounted a deflector 16 comprising a pair of vertically curved plates joined to form a V. The deflector 16 is mounted above the track approximately the same distance as the blower, by means of suitable brackets 17, to any convenient portion of the tender frame, with the apex of the V located midway between the rails and pointing toward the blower.

It will be obvious from an inspection of Figs. 4 and 5 that the material lifted from the tracks by means of the steam jets from nozzles 12 will be directed horizontally by the jets from the nozzles 13 along the surfaces of the deflector 16, which will act to throw the material laterally away from the track." It will further be obvious from Fig. 4that the material raised by the jets from nozzles 12 will, if the nozzles 13 are omitted, strike the deflecting plate and tend to be deflected outwardly thereby. At the same time the overhanging curved upper portion of the deflector 16 will tend to deflect the flow into a horizontal direction and for this reason the jets from nozzles 13 may be in many instances smaller than those issuing from nozzles 12, and may even be omitted entirely under certain conditions where the steam jets issuing from nozzles 12 are sufliciently powerful not only to raise the material from the track, but also to force it along the surfaces of the deflector 16 with suflicient force to throw it beyond the tracks.

Referring now to Figs. 2 and 3, I have illustrated the blower as applied to a locomotive, with the deflecting shield omitted. In this case where no deflector is used, the general arrangement of the pipes 8 and 9, attached to the inlet supply pipe v3', is as previously described. The nozzles 12 are located in the same position relative to the track as the vertical nozzles described in connection with the preceding form, but it is to be noted that in this case the nozzles are directed rearwardly tail in Figs. 6 and 7, the same as that used for the vertical nozzles, but the horizontal nozzles are placed with the angular tips directed laterally away from the center hne of the track. In this form the laterally directed horizontal jets form the sole means for blowing the material raised from the track laterally away from it.

The nozzles 15 (Fig. 5) and 15 (Fig. 3) are provided for the purpose of clearing the switchlights adjacent to the tracks over which the cleaner is passed. The deflector, or the laterally disposed jets, throw large quantities of materialto one side or other of the track and this material lodges uponand obscures switchlight and similar equipment, and this is subsequently cleared of the accumulation by the jets from the nozzles 15 or 15, which impinge thereon after the passage of the main portion of the blower.

From the foregoing description, the operation of the device is obvious. Steam is admitted to the blower through the control valve 23 and the locomotive is then run slowly over the tracks to be cleared. Depending upon the depth and character of the snow or ice to be removed, the locomotive speed should be in the neighborhood-of from 2 to 4 miles per hour. As the blower is moved over the road bed, thesteam jetsfrom the row of nozzles 12 or 12', which are moving in the direction in which they are pointed, act not only to 'loosensnow and; ice by" melting, butalso exert a powerful prying action, which tends to lift it from the track. In effect, the steam from these jets ricochets from the track surface and carries upwardly with it all loose material which may be lying on the road bed. The material thus thrown upward by the jets from nozzles 12 or 12' is blown by the jets from nozzles 13 or 13' from the center of the track outwardly "and away from the road bed to be cleaned. It will be obvious that the nozzles 12 or 12' located adjacent to the railwill direct powerful jets of steam into the switch points to thoroughly clean them, and the other jets will have the same effect on frogs and crossovers over which the locomotive may pass. Furthermore, in the case of fine, dry snow, which driftsreadily,the-action of the blower is more'efi'ective than hand cleaning, as the snow which is cleared from the road bed by means of the steam jets is moistened to a considerable degree by the condensation of the steam. This wet snow thrown out by the blower tends to pack and remain where it falls rather than drift'back upon the tracks.

As previously stated, the locomotive should be run during the cleaning operation so that the nozzles 12 or 12, as the case may be, are directed forwardly in the direction of motion. For this reason, the nozzles 12 in the blower located-at the forward end of the locomotive are placed with the jets directed toward the rear of the locomotive and in operation the locomotive is run backward. If the position of the nozzles were to be reversed and the locomotive run forward, the cleaning action would not be impaired, but the cloud of steam and snow raised by the blower is so great that the engineers view would be seriously impaired and consequently the arrangement shown is used, and the locomotive run backward in order that the engineer may have a clear-view in the direction of motion, with the cloud raised bythe blower behind him. When the blower is located under the tender, the nozzles 12 are forwardlyfdirected with respect to engine and tender and ,theengine-is run forward in the normal manner, as in this case the cloud raised by the blower is behind the engine cab. As the direction of the nozzles with respect to the direction of motion is always forward, the term forwardly is to be understood as referring to direction of movement, irrespective of the direction in which the nozzles may be mounted with respect to'the unit of rolling stock to which the blower may be attached.

Obviously, either of the forms of blower which I have described may be attached to a suitable unit of rolling stock wherever desired, andsteam for the blower may besupplied either from the locomotive boiler or from other sources of steam supply. In the forms which I have shown for illustrative purposes, the blowers are attached by easily removable means so that they may be removed when not in actual use, but either form of blowermay readily be attached to a special car, adaptedr to be coupled to a locomotive when occasion arises to use the blower." a
