'LOCOMOTIVE SNOW OR ICE FLANGER.

SPECIFICATION forming part of Letters Patent N0. 544,120, dated August 6, 1895. Application filed December 18, 1894- Serial No. 532,153. (No model.)

To all whom it may concern.-

Be it known that I, AUGUSTUS F. PRIEST, of

Duluth, in the county of St. Louis and State I dangers such as shown and described in Letters Patent of the United States No. 398,347, dated February 19, 1889; No. 455,724, dated July 7, 1891,'and No. 467,394, dated January 10, 1892.

The object of the invention is to provide a new and improved locomotive snow and ice fianger, which is comparatively simple and durable in construction, very efiective in operation, and arranged to permit the engineer in the cab to conveniently raise or lower the hanger-blades and to properly guide thesame in their up and down motion, and to hold the knives in proper position relative to the rails to effectively clean the snow, ice, sand, or other material therefrom.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then poi nted out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 is aside elevation of the improvement with parts in section. Fig. 2 is a 'sectional plan View of part of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged transverse section of the same on the line 3 3 of Fig. 1 with parts removed. Fig. 4 is an enlarged side elevation of the guideways and cross-bar, the latter being in section. Fig. 5 is a sectional plan view of the same, and Fig.- 6 is a front. view of one of the danger-blades with part broken out and the knife in a detached position.

The locomotive A, on which the improve ment is applied, is of the usual construction and is provided at the front truck B with equalizer-bars 0 extending from the front truck-box B to the rear truck-box B as is plainly illustrated in the drawings. Each equalizer-bar O is formed at its front end with a notch O fitting over the front truck-box B.

(See Fig. 4.) The head 0 of the equalizerbar is provided with guideways formed by U-shaped bars 0 forming with the'front edge of the head 0 a vertically-disposed slot G on which is fitted to slide vertically the cross-bar D, carrying on each end a dangerblade E. From the rear of each head (3 extends an angle-iron C engaging with its inner end C the rear face of the corresponding truck-box B, (see Fig. 2,) so that the head 0 formed with the guideways for'the crossbar D, is protected against lateral outward motion, while the notch O in the equalizer guards against longitudinal motion and causes the strain on the flanger-blades E to be taken up by the front truck-box B. Each fiangerblade is provided with a reinforcing-plate E, a deflecting-plate E and a cutter-knife E the latter formed at its lower edge with a notch E for the passage of the rail-head, as is plainly indicated in Fig. 3. Each flanger-bladeEstands at an angle to the truck-rail, as is plainly illustrated in Fig. 2, (see also Fig. 5,) so that the snow and ice or other obstruction is moved to the outer side of the rail on the forward motion of the locomotive.

The cross-bar D, supporting at each end one of the danger-blades E, is provided at its extreme outer end with an angular extension D and with an angle-iron D bolted or otherwise fastened to the cross-bar D at the front face thereof. This angle-iron D is provided with the end D in alignment with the extension D, as is plainly shown in Fig. 2, and on the end D and extension D is bolted the reinforcing-plate E, previously mentioned. The latter extends" a short distance below the lower edge of the cross-bar D, (see Fig. 6,) and on this depending end is held the cutterknife E while on the upper end of the reinforcing-plate extends upward and forward the deflecting-plate The cutter-knife E is formed at its upper inner corner with a notch E and on the outer upper corner with an opening E as is plainly shown in Fig. 6. The notch E is adapted to engage a shoulder-bolt E screwing in a depending end of the reinforcing-plate E, while the aperture F. isadapted to be engaged by a bolt E held on the reinforcing-plate E. Now it will-be seen that when it is desired to remove the cutter-knife E it only requires the removal of the bolt E, as the knife can then be pulled outward by disengaging the notch E from the bolt E, which remains stationary in the reinforcing-plate E. By the arrangement described the cutter-knife can be readily removed when worn out or broken and replaced with a new one without much difficulty by simply manipulating the one bolt E The lower ends of the deflecting-plate and the reinforcing-plate are fastened by the same bolts E to the extension D and the angle-iron D as is plainly illustrated in Fig. 5. The cross-bar D is connected with the lower ends of the links F, extending upwardly through apertures in the bufferbeam B and the upper threaded end of each link F carries a head F, formed in its forked ends with vertically-disposed slots F engaged by a pin G, carried by an arm G, secured on a transversely-extending shaft H, mounted to turn in suitable bearings I, secured on the frame of the truck B. (See Figs.

' 1 and 3.) One outer end of the shaft H is provided with an arm J, pivotally connected with a longitudinally-extending sliding-bar K, arranged alongside the boiler of the 1000- motive and resting on a suitable guideway A, as is plainly illustrated in said Fig. 1. The end of the bar K nearest the cab of the locomotive is provided with an aperture K, engaged by the upwardly-projecting end L of a pistonrod L, held on a piston mounted to slide in a cylinder N, connected at its outer end with an air-pipe 0, extending through the cab of the locomotive to a suitable compressed air supply, the said pipe being provided within the cab of the locomotive with a valve 1, under the control of the engineer, to permit the latter to charge the cylinder N with compressed air to force the piston in the cylinder N inward to move the bar K in the direction of the arrow at to raise the flangerblades E. When the engineer turns the valve P to out 01f the air-supply and to permit the air in the cylinder end to escape, then the fianger-blades E are lowered to bring the cutter-knives E in proper relation to the rails to clean the latter of snow, ice, and otherobstructions. Now when the bar K moves in the direction of the arrow (1'', then the knife-edge is turned by the connection of the knife with the bar K, and the shaft H causes an upward swinging of the arms G, so that their pins G travel to the upper ends of the slots F to then pull the heads F and links F in the proper direction to cause the cross-bar D with the flanger-blades E to move vertically upward, the said cross-bar traveling in the guideways of the equalizer-bars C. When it is desired to lock the flanger-blades E in this uppermost position the engineer connects the link Q with the hook end K of the bar K to hold the latter in a locked rearward position, as indicated in dotted lines in Fig. 1. A link Q is pivoted on the support A near the cab of the locomotive, so that the engineer in charge of the locomotive can throw the link down to engage the hook K whenever desired.

It is understood that when the dangerblades E are moved into the lowermost position their downward motion is limited by the cross-bar D resting on the bottom of the slots 0 formed by the bars C, (see Fig. 4,) thus bringing the lower edge of each flangenblade in opposite relation with the head of the rails to prevent the sides and top of each notch E from striking the sides and top of the railhead during the time the locomotive travels over the track.

It is understood that the blades are raised by the engineer in charge of the locomotive whenever the locomotive approaches guiderails, crossings, doc, to prevent the cutterknife from striking the fixed obstructions on the track. Should the cutter-knives, however, be struck and broken, then the rest of the device is not seriously aifected, it being understood that the damage can be easily and quickly repaired by fastening new cutterknives in position on the reinforcing-plate E in the manner above described.

It will be seen that by the construction described the danger readily conforms to all irregular surfaces in the track, whether vertical or lateral, and gives an even depth of cut everywhere, doing exactly the same work on curves as on straight lines, and throughout the cutting operation the knives do not, under any circumstances, touch the rails.

By reference to Fig. 2 it will be seen that the angle-iron D abuts against the inner faces of the blades E to prevent lateral movement of the crossbar D in its guideways, so that there is no danger of the sides of the notches E striking the rails. By making the head F removable on the link F the latter can readily be passed through a comparatively small hole in the buffer-beam from below, thus obviating the necessity of large holes in the beam and consequent weakening of the same. The head F is slotted to permit the pin G to play up and down therein, caused by jars, 850., without affecting the crossbar and flanger-blades While in a lowermost position. It will further be seen that the device is absolutely safe to operate on any and all trains, as it is properly locked and braced, and it perfectly cleaus the rails for every wheel in the train, leaving no snow to absorb the power through contact with the oil-holders. No derailment can possibly occur by reason of engine or truck-wheels mounting ortraveling on hard-packed snow on the track. By arranging the device directly behind the pilot it is entirely out of the way and not liable to be accidentally injured by an obstruction on the track moved to one side by the pilot.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A fianger, provided with a cross bar for end bent to stand at an angle to the bar, and
