SNOWPLOW.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed. July 30, 1918. Serial No. 247,353.

To all whom it may (JO/LC'P/L Be it known that I, ORA BERRY, a citizen of the United States, residing at Princeton, in the county of Gibson and State of Indiana, have invented new and useful Improvements in Snowplows, of which the following is a specification.

This invention relates to snow plows, the object in view being to produce an efficient snow plow especially adapted to be attached to the front of a railway locomotive for the purpose of clearing snow from the tracks, the improved plow embodying a novel arrangement of heating means whereby the entire surface of the plow is efliciently heated to facilitate the snow shoveling, plowing and removing operation.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as herein described, illustrated and claimed.

In the accompanying drawings:

Figure 1 is a fragmentary side elevation of a locomotive showing the improved snow plow in its applied relation thereto.

Fig. 2 is a front elevation of the same.

Fig. 3 is a vertical longitudinal section through the plow.

Fig. 4 is a horizontal cross section through the same.

The snow plow contemplated in this invention is made of sufficient size to cover the cow catcher or fender 1 of a locomotive and also entends sufficiently above said cow catcher to cover a good portion of the boiler 2 of the locomotive, the plow being made also of sufficient width to extend in front of the wheels 8 of the locomotive.

The plow body is of hollow formation, comprising a front wall 4 and a rear wall 5, thereby leaving a steam space 6 between the front and rear walls, as shown in Fig. 4. The plow is shaped as indicated in Figs. 2 and 4 to provide a central vertical ridge or prow 7 from which the side portions of the front wall 4 incline rearwardly as indicated in Fig. 4, so as to part the bank of snow in the center and force the same equally to 7 both sides of the railway. The rear wall 5 nected with the walls 4 and 5 are baflie plates 8 and as will be noted in Fig. 3, the plates 9 are alternately attached at one treme edge to one of the side walls 9 of the plow body and terminate at their opposite ends short of the opposite wall 9 so as to leave steam passages or ports 10. It will be noted that the ports 10 are arranged alternately opposite each other in staggered relation to each other. A steam supply pipe 11 extends to and communicates with the top of the plow body and adjacent to the lowermost plate, one of the side walls 9 of the body is formed with a steam outlet or exhaust port 12. As a result of the construction described, steam is caused to circulate at a comparatively slow rate of speed throughout practically the entire area of the interior of the plow, thereby maintaining the working surface of the plow in a heated condition for the purpose above stated. The plow body is supported in relation to the locomotive by means of upper and lower braces 13 and 14 as shown in Fig. 1, whereby the plow is rigidly fastened to the frame of the locomotive and adapted to sustain the pressure to which it must necessarily be subjected when operating on heavy snowdrifts.

It will be observed that the battle plates not only form steam passages and ports, but also connect and brace or reinforce the walls 4 and 5. By this means the plow shell is strengthened against collapse under the crushing strains to which it is subjected without the use of internal bracing other than that of the baflie plates themselves.

The steam supply pipe 11 connects with a live steam supply pipe 13 and also with a steam supply pipe 14 which may lead from the steam exhaust of the air pump. Steam from either one or both of these sources may, therefore, be supplied to the plow. In practice, the pipe 13 may be provided with a suitable controlling and cut off valve located within the engineers cab. A pipe 15, provided with a cut-off valve 16, connects the pipe 14 with the smoke-stack, and a valve 17 is arranged between the two pipes 11 and 14, whereby, when steam from the pipe 14 is not used to heat the plow, such steam may be discharged into the stack to augment the draft.

I claim The combination with a moving vehicle, of a snow plow mounted at a downward and forward angle of inclination upon the front of the vehicle, said plow comprising a body of hollow formation and composed of front and rear walls disposed in spaced relation to each other to provide a shallow intervening chamber said plow body embodying a pair of arcuatelyshaped wings meeting at the center to provide a splitting ridge and thence extending outwardly and rearwardly toward their side edges on curved lines to provide concaved and laterally sloping faces on opposite sides of the ridge said ridge being of maximum extent of projection at the top of the body and thence gradually diminishing in extent of projection toward the bottom of the body, horizontal transverse partition plates arranged within the chamber of the body to provide staggered steam passages, and a steam pipe com municating with said passages, the body being provided with an exhaust outlet also communicating with said passages.

In testimony whereof I aflix my signature.

ORA BERRY.
