Suiter Swantz IP takes a look back at past inventions and inventors with our Patent Of The Day.
On this day in 1903, James W. Russell was granted U.S. Patent No. 721,241 for a SNOW PLOW.
My invention relates to snow-plows for railways; and its object is the effecting of the improvements briefly enumerated as follows: first, to means for simplifying, improving, and cheapening the construction of the wings of the snow-plow for enabling the snow to be better delivered from the wings and preventing the same from being deposited upon the rear or cab roof or falling back upon the track, for strengthening the pivotal support of the wings, for so arranging and constructing the wing-operating mechanism as to provide room in the cab for the introduction of flanger-operating mechanism and to give a central passage for the men from end to end within the plow, and also for so improving the wing-operating mechanism as to permit it to be more easily and quickly manipulated and so as to prevent accident to wing or plow in case of excessive pressure against the wing when in use; second, to improvements in the hooding or fender at the top of the nose of the plow for adapting it to more readily” clear itself of the snow which might otherwise pack beneath it and to means whereby any undue excess of pressure shall simply break the fastenings of the fender-extension plate and dislodge it instead of buckling and destroying the hooding or fender itself; third, to improvements in the power-bar for giving it increased rigidity and strength and for providing it with an automatic coupler; fourth, to an improved draw-bar for enabling the plow to be coupled behind an engine or as apart of a freight train in being transported from one point to another; fifth, to means for enabling a flanger to be combined with a wing snow-plow and to improvements in the construction of the flanger itself and in the flanger – operating mechanism; sixth, to improvements in the side cutters of the plow and to means for strengthening and bracing the hanging sides or guards of the plow; seventh, to certain imitation of one-half of said flanger improvements.
