UNITED STATES PATENT OFFICE.
PAUL GRAEB, OF BERLIN, GERMANY.
APPARATUS FOR CLEANING SNOW lFROM RAILROAD-TRACKS.
SPECIFICATION forming part of Letters Application filed iipiii 2o, 1889.
To all whom it may concern.;
-Be it known that I, PAUL GRAEB, professor on theRoyal Polytechnicum, of Berlin, in the Kingdom ofPrussia and German Empire, have invented a new and useful Railroad Snow- Plow, of which the following is a specification, reference being had therein to the accompanying drawings.
rlhis invention relates to railroad snowplows, and has for its obj ect to provide an effective snow-plow byr means of which the snow will be removed from the center of the track and iiung on each side thereof.
The invention consists in a railroad snowplow constructed and arranged as herein after described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this speci iication, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is aside View in longitudinal section of a pilot-car with a sn ow-plow constructed Fig. la is a view of the forward part of a locomotive with pulley and chain broken away which connect with the plow. Fig. 2 is a plan view, with parts broken away, of the pilot-car and snow-plow. Fig. 3 is a ,rear view, partly in transverse section, of the pilot-car and snowplow. Figs. 4. and 5 represent transverse sections of the blades of the plow, taken through points near the hub and outer extremity, respectively.
Two pairs of helical blades a are placed in front of a carriage b in such a manner that one pair of helical blades works at the side of and in advance of the other, as indicated in the plan, Fig. 2. The diameters of these pairs of helical blades are from about one to three meters, according to the gage or width of the road or path to be cleared. The pairs of helical blades are also so arranged that the corresponding to the profile or configuration of the surface of the road.
The pairs of helical blades a are fixed upon shafts c, which receive rotary motion from the axle of the frontwheels ofthe locomotive or the former case-that is to say, when the snow= plow is worked by the axle d of the front wheels Patent No. 412,496, dated October 8, 1889.
Serial No. 307,943. (No model.)
is adopted: A chain-wheel e is fixed on the axle d of the front wheels of the locomotive d', and by means of an endless chain e drives a wheel f, keyed on a shaft f on the snow-plow carriage b. The endless chain is so arranged as to admit of being readily removed from and replaced on the chain-wheels, and is of a suitable weight to enable it to drive the wheels without slipping, even when the bulfers between the plow and the locomotive are pushed as far as they can go. The shaft f is also so arranged that the rear axle h of the wheels of the plow-carriage does not come in the way of the chain. A toothed wheel il is keyed on the shaft f and drives an intermediate wheel k, which transmits motion through a wheel m c, carrying the pairs of helical blades a. This driving-gear is so arrangedas to obtain an accelerated motion, so that the pairs of helical blades revolve rapidly and cast the snow onto the banks on either side of the road.
There'may be any suitable number of -helical blades which are so arranged that the part near the center of rotation projects forward into the face of the drift or mass of snow, so that the central part of the blades engages with the snow before the otherpart and gradually works the snow away to the outer ends. The front edges of the blades are also curved, so that they out into the snow like shovels and pare it off. The lower or outer ends of the blades are likewise curved like shovels to enable them to carry up and fiing away the snow on the side banks, Figs. 4. and 5. By these means the helical blades are enabled to act in a similar manner to shovels in their rotary movement. The rapid rotation of the blades, which is regulated bythe rate at which the plow advances, causes the snow to be quickly caught up and thrown off at the sides. When the pairs of helical blades are driven by the axle of the plow-carriage, one of the axles of the carriage b is provided with a chain-wheel of the saine or similar form to the wheel e. on the axle of the front wheels of the locomotive, and which, by means of an endless chain, drives the chain-wheel f, or, aceording to another arrangement, the chain and chain-wheels e f are dispensed with and the movement is transmitted direct from the axle of the locomotive-the following arrangement `h or h to the gearing c' 7c fm.
and shaft Z to bevel-gear p o and to the shafts Y ICG By suitably modifying the details of construction the plow may be employed for elearing away snow from streets7 roads, or other places.
That I claim, and desire to secure by Letters Patent of the United States, is
l. A snow-plow consisting of a carriage having mounted thereon rotary shafts of different lengths and projecting forward from the carriage, helical blades mounted on the projecting ends of the rotary shaft, the blades on one shaft being in advance of and at one side of the blades on the other` shaft, and a driving mechanism connected with the rotary shafts, substantially as shown and described.
