HARD-SNOW AND ICE PLOW FOR RAILWAYS.

Specification of Letters Patent.

Patented May 29, 191 '7.

Application filed March 24, 1917. Serial No. 157,187.

To all whom it may concern:

Be it known that 1, JOHN W. VON NEIDA,

a citizen of-the United States, residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Hard- Snow and Ice Plows for Railways, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to snow plows or snow shovels, such as are applied to railway cars, street cars, and other like vehicles, and particularly to plows used for removing snow, ice, miid, etc., from the rails of the track.

While the ordinary snow plow is designed to remove masses of snow from the track, it

the track itself, nor from the fiangeway, whether this flangeway be formed in the rail, as is the case in cities, or whether it is simply formed by having the rail high enough to ermit the flange of the wheel to operate. ccumulations of hard snow'and often cause the flanges of the locomotive or motor car to ride up on the hard snow or ice and the engine or motor car to jump the track. It is usual 'to clear this ice and packed snow away from crossings and from rail tracks by hand labor and this labor is particularly hard and it takes considerable time to properly clear the crossing.

The general object of my invention is to provide a snow plow or shovel adapted to be disposed on an engine or motor car-and so constructed that it will not only throw loose snow andice to the sides of the track, but will scrape oil the hard snow and ice from the top of the rails and cut out the hard snow and ice from the flangeway.

A further object of this invention is to provide for the purpose of cutting a passage for the flange of the wheel, an auxiliary cleaning point which extends down on the inside of each plow and on the inside of the rail and which cuts out'thehard snow and ice which may be gatheredthere, 5

A further ob'ect is vto provide for aplurality of scraping members which are urged downward resiliently against the face of the rail and which act to cut away and scrape off the snow or ice which may have hardened u on the rail and in this connection it is an o ject to so mount these scrapers that they may ride over the rail and will not get caught at the joints or when passing other ra1l connections.

And still another object is to form the scraping ends of these scrapers of such form that they will ride properly over the rail, provide resilient means for forcing these points or scrapers down against the rail, and to provide means for preventing the points or scrapers from dropping too far.

A further object is to provide means whereby the rail scrapers may be readily removed to permit of resharpening and replacement and to provide means for sup porting each plow upon the rail so that in case a brace gives away, the plow points will not drop down so as to engage the rail .or the-ties.

does not remove hardened snow or ice from i the followin Other objects will appear in the course of description. My invention is illustrated in the accompanying drawings, in which Figure 1 is a top plan view of a locomotive equipped with my improved ice and .snow plow;

ice on top: of the rail'and in the flangeway I proved plow;

Fig. 3 is a fragmentary sectional View on .the line 3-3 of Fig. 5;

Fig. 2 is an inside elevation of my im- Fig. 4 is a fragmentary front elevation of one of the plows; Fig. 5 1s an end view of the constructionillustrated in Fig. 3;

Fig. 6 is a perspective View of one of the Disposed at eachside of manner and extend downward to within a short distance of the rail and transversely across it and forward. Attached to the lower ends of each of the main plows 12 is a plow point 13 which is removably con- 1 nected to the plow share 12 so that it may he removed for resharpening. Extending inward from the lower end of each main plow share 12 is a relatively small shovel or share 14:, which is braced from the main share 12 by means of the brace 15 and which has detachably connectedto its lower end, the downwardly and forwardly extending cutting point 16, which extends down below the lower edge of the large point 13 and is perforations.

perforated for the passage of extending stems of a plurality'of'scrapers designed to operate very close to the inside of the rail 11, so as to cut a flangeway for the flange of thewheels.

Extending in a vertical planerearward from the forward end of each share 12 is the runner 17 ,which isdi-sposed a shortdistance above'the rail and which, at its rear end, is attached to the'pil'ot of the engi ne by means of braces 18 and which, at its middle, isconnected- 'to' the pilot of the engine by means of the braces-19. "A trans verse brace 20 is-attached to the middle of the pilot 10, in anysuitablemanner, and extends laterally therefrom and is connected to the runners 17 in any suitable manner.

'lh-isbrace' 2O-braces the shares 12 fromeach other and rigidly connects the shares to the pilot of the engine. A brace 21 connects =each wing or share '12 to its corresponding runner 17 so -as=tobrace the one from the other. Attached to -each runneradjacentits forward end is a block of extrahardsteel designated '22,- having upward-1y rounded forward: and rear ends. -These blocks- 22 slide'on the face of the rail and actto keepthe nose of each plow from dropping downward-0n :the track in case t-he brace gives away. These blocks 22 are about% wide and 3 1 inches long.

Adjacent therearend of-eachrunner 17 is a=metallic member 23-which carriesupon it a spring 24c,-which-is coiled around a b'olt or stud 25, this spring being coiled' a plural- -ity of times and then extending forward as at 26 and being formed with aplurality-of =Also' formed upon each runner 17 is a plurality of collars 27-whichare the vertically 29. lbWill thus be seen that the stems 28 of the scrapers 29- maymovevertically in the collars: 27. Ihe-s temsareslotted: and pins 31 on thewoHars-pass through these slots. The lower faces-of the-scrapers 29 are-beveled so as to provide a cutting-edge 30,"Wl1l0h scrapes along the upper face of the :rail. downward by 'theispring 24 and 26 and their :downward movement is'limitedby the pins The cutters orscrapers are forced 3 1. 'Thesepins also prevent the stems 28 fromldropping too far through the collars. Thezupper'encls of the steins 28 are formed pass through: the perstuds- 32 being provided" with cotter pins for which holding Ithe stemsr 28 to the spring portion It will be, of course, understood that the spring portion 26 is of such strength as to "urge theselu'gs 'in'to firmcutting engage- -ment with-the surface of the rail but that because of the resilient mounting of these rail scrapers or points, they will yield on passing over joints. This movement of the =rail-=scrapers or outters is also made easier by the beveling of the lower faces.

It will'be seen th'afl Phave provided'main shares for forcing-loose-=snow and' ice'from above "the rail, a plow *point which cuts a cl-rannel -for the flange of the "-wheels,'* and 'scrapers'which cut away the thindce' on the 'topof the rails. The lower edgesbf the runners 17 and the lower-edges "of 'the plow 'shaifts' 12 and *points 13- are suppdrtd'tdbe set about above tithe"- trahk "to, -prevci1t catching with rail *eonnctions at messing-s. The rail scrapers 29 scrape the rail bare. These are so arranged as to 1 accommodate themselves' to joints in -the' rails and are 'wide" enoughand have; sufficient bevleP-to cover any crossing or switch. Thisfplow can i be 1 put on 1 large engines used "in" eonnectionwith ordinary sn'ow plowsand hen be put on'iargestreet ears and interurban ears. With-this atta chmeht a'track- -may 'be cleared :no Inatter how hard thesnow or ice is'frozen and is particularly adapted for ity "crossings. A plow constructedin accordance-with my invention can doas"- mu ch 'elearing' work un 15 min'utes as ean he done'by lilo men working =ten hourswith *pick and sho'vel in theordinary manner.

While I h'ave illustr'ated Gertain details of construction -which I! have found -to be "particularly effective; I wish it understood that these i -detaiis might be modified *in many ways without dep a rting fro-m the-*s1 i rit of the in-vention. 4
