SPECIFICATION forming part of Letters Patent No. 446,773, dated February 1'7, 1891.
Application filed May 21,1890. Serial No! 352.605. (No model.)
To aZZ whom, it may concern: is held a self-reversing knife J, secured on Be itknown that 1, JOHN W.

In the ear B is mounted to turn ground or track into the back of the casing in suitable bearings the longitudinally-arat its bottom without obstructing or crowdranged 'main driving-shaft O, supporting at ing the knives J and the front parts of the its outer end a wheel D, mounted to turn in a paddles II when they pass into their lowersuitably-construeted casing E, secured on the most position on the revolving of the wheel. 3 5 front end of the car 13, and provided on top The operation is as follows: \Vhen the car with an outlet F, through which the snow is B is pushed forward, the shaft 0 is rotated discharged to either side of the track, the by suitable means, so that the wheel D resaid outlet being preferably provided with a volves within the casing E. hen the wheel suitable deflector, so as to change the direocomes in contact with the snow, the rear 0 tion of the snow as desired. edges of the cutting-knives J are forced back, The wheel D is provided with a back plate and the advancing edge is thrown forward to G, from which extends at right angles toward engage the snow,whieh is thus cut and thrown the front a series of radially-arranged padback between the paddles H.

The wheel in revolving in the opposite direction causes the paddles II to throw the snow to the other side of the track. 13y constructing the wheel as described great strain at the center of the wheel, caused by the snow separating and crowding it to the outside, is entirely avoided. As will be seen, the snow enters unmolested into the space I until it passes that point where the paddles are already tilled with snow cut by the knives J, the core of the snow thus passing into the space I and traveling up, after being cut by the cutting-bars L, the cone K to the rear of the paddles to be discharged, as previously mentioned. The snow entering the casing It at the bottom N also passes to the rear of the casing to be operated on by the paddles II at their rear ends to be carried up and discharged through the opening F, as previously described. The strain is thus removed from the center of the wheel, whereby the latter can operate with greater freedom and discharge the snow at a high rate of speed.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a rotary snow-plow, a wheel com prising a back plate mounted to turn, a series of paddles extending radially and at right angles from the front face of the said back plate, the apexes of the paddles terminating near the center of the back plate and arranged parallel to the axis of the wheel, so as to form a central space on the faceof the said back plate, and a cone secured with its base centrally on the face of the said back plate and extending freely into the said central space, substantially as shown and described.
