SPECIFICATION forming part of Letters Patent No. 400,154, dated March 26, 1889.

Application filed November 27, 1888. Serial No. 291,983. (No model.)

To all whom it may concern.-

3e it known that I, OREN WILLIAMS, of

Gouverneur, in the county of St. Lawrence and State of New York, have invented a new and Improved Snow-Plow, of which the following is a full, clear, and exact description.

My invention relates to an improvement in snow-plows, and has for its object to provide a plow of simple and durable construction which will expeditiously remove the snow from the track, leaving a solid compact wall at each side; and the further object of the invention is to transport the snow as removed to quite a distance at one side of the track.

The invention consists in the novel construction and combination of the several parts, as will be h ereina'fter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the device. Fig. 2 is a central vertical longitudinal section. Fig. 3 is a partial plan view; and Fig. l is a transverse vertical section taken on line 5cm of Fig. 2, illustrating the relative position of the horizontal and vertical conveyers.

In carrying out the invention the body of the snow-plow is constructed similarly to a box-car and is mounted upon suitable trucks. The box-body 10 is adapted for the reception of an engine, (which is not illustrated in the drawings) the driving-shaft 1O thereofonly being shown.

From each side of the box-body arms 11 are forwardly projected, as best shown in dotted lines, Fig. 1, and a second or outer frame is constructed at each side of the body, the same consisting of metal arms 12, extending parallel with the mainframe arms 11 from the outer extremity of said arms to a point at or near the center of the box-like portion of the body. The outer-frame arms 12 are held a distance from the main arms 11 by studs or posts 14, intervening, respectively, the forward extremities of the outer and inner arms and the inner extremity of the outer arm and the box-like body.

Between the inner body-arms, 11, a wheel, 15, is journaled, consisting of a drum, 16, mounted upon a suitable axle, 17, the said axle being journaled in both the outer and inner arms, 11 and 12, as best illustrated in Fig. From each end of the drum 16 an annular flange, 18, is upwardly projected, and the said wheel is divided into a series of pockets, 19, through the medium of transverse semicircular partitions 20, extending from end to end of the drum and secured to the flanges in any approved manner. The partitions 20 are made to terminate a slight distance from the outer edge of the flange, as best illustrated in Fig. 2, and the said partitions are so located that their concave faces will be in direction of the revolution of the wheel.

In front of each. of the partitions 20 a radial slot, 21, is produced, the center of the circle of which slots is immediately above the partitions, at which point the upper ends of discharge-plates 22 are pivoted, one plate being provided for each pocket. The free ends of the plates 22 are provided with pins 23 integral therewith, which pins ext-end outwardly parallel with the longitudinal face of the plates through the severalslots 21, as best illustrated in Figs. 1 and 2.

A trip-plate, 24, is rigidly attached to the inner face of each of the frame-arms 11, which plate is provided with a cam-face, 25, illustrated in dotted lines, Fig. 2, and extends upward above the horizontal plane of the drum portion of the wheel from a forward point, a, to a rear point, I), the point a being so located that when the partitions reach the same they will have assumed virtually a vertical position, and the point I) is so placed that the said partitions when reaching the said point will have virtually assumed ahorizontal position, as is shown in Fig. 2. The cam-face 25 of the trip-plate is curved, which curve, commencing at u, is gradually swelled to the rear and carried sharply down to the point 11.

Between the wheel and the box-body 10 an essentially T -shaped tubular casing, 26, is located, the horizontal member whereof constitutes the base. The upper member, which intersects the horizontal member, is vertical a portion of its length only, and is then car ried at an inclination outward above the boxlike body and beyond the same.

In the horizontal member of the casing 26 two screw conveyers, 27 and 28, are held to revolve, one conveyer being formed with a right-hand pitch and the other with a left hand pitch. The inner ends of the two conveyers are stopped at each side of the center of the horizontal member of the casing, and between the approaching ends of the two horizontal conveyersa short vertical conveyer, 29, is journaled in the casing, which latter conveyer extends upward within the tubular sec tion of the casing. To the upper end of the vertical conveycr 2!) a second conveyor, 30, is hi nged, the latter conveyor being made to pro ,ject upward within the inclined portion of the the discharge-plates remain in antmtward pocasing to the top thereof, at which point the shaft oi the conveyer journaled in suitable bearings, 33]. llpon the outer end of each of the horizontal (-onveyers "27 and 28 a spurgear, 32, is secured, and a pulley, 33, the same being located between the inner and outer arms, ll and l2.

The drive-shaft is provided at each end with a large pulley, 34-, and a smaller pulley, 35, the pulleys 35 being belted. to the pulleys 33, located upon the horizontal eonveyershafts, as best illustrated in Fig 1 and 3.

The shat't.1.7of the wheel is provided near each ext: emity,between the arms 11 and 12,wit h a spu rgear, 36,wh i ch spur-gea r meshes with a pinion, 37, secured to a spindle, 38, jonrnaled between the arms 11. and 12, as best shown in Fig. 3, the said spindle being also made to carry a gear, 33$ slightly smaller than the wheel-gear 3b, which gear meshes with the gear 32, secured to the horizontal convcyershai This arrangement of gearing is designed to admit of a rapid motion of the lower conveyors and a cmnparativel y sl ow revolution of the wheels.

The upper vertical. and connected inclined conveyers are adapted to be revolved at least once and a hall or twice as fast as the two lower or horizontal. conveyers, and to that end upon the lower extremity of the vertical conveyor-shatt a-bevel-gear, 40, .is secured, meshing with a second bevehgear, -.1-l., secured to one end of a shaft, 42, journaled longitudinallybeneath the plow, the rear end of which shaft is provided with a similar bevel-gear, 4-25. 'lhrough the latter bevel-gear a connection is made with the drive-shaft '10, the same being effected by journaling a shaft, ll, beneath the box-body 10, which shaft ii is provid ed with a bevel-gear to mesh with the gear 43, and a pulley, l5, belted to the larger pulley, 3-1, of the drive-shalt it), as illustrated in Fig. 1.

A hopper, 44', is attached to the forward side of the casing 26, which hopper extends from side to side of the main .t'rame of the plow, and communicates with the hm-izontal and vertical portions oi. the said casing. The forward end of the hopper is open and faces the wheel.

In operation, as the plow is carried forward through the bank of snow, the dischargeplates of the. 'lorward pockets will be forced brought in contact with the outer edge of the slot 91. The snow is at this point discharged into the hopper at}, as illustrated in Fig After discharging the snow into the hopper sitionthat is, with their pins in the outer ends of the slotsuntil again pressed inward by the snow, as previously described. Thus the snow is continuously delivered from the severalpockets of the wheel into the hopper and upon the several horizontal conveyors and the lower portion of the vertical conveyor. The lmrizontal conveyors carry the snow from the sides of the plow and deliver the same to the vertical conveyor, from wh ich it passed to th e inclined conveyer and delivered by the latter conveyor a distance beyond the side of the track. As the inclined and vertical conveyers are made to revolve at a much greater speed than the horiztmtal conveyors, they are enabled to carry ol't' all the snow delivtn'ed by the latter without inconvenience or choking.

11: in practice it is found desirable,the gearing contained between the arms 1 1. and .12 may be inclosed by any suitable :l'orm of casing.

I desire it to be distinctly understood that I do not confine myself to the mechanism illustrated for driving the snow-wheel and conveyors, as any other well-known or approved means maybe employed without departing from the spirit of the invention.

Having thus described my invention, 1 claim a s new and desire to secure by Letters llatent-- 1. In asnow-plow, the combination, with a pocketed wheel, of horizontal ctmveyers and an essentially vertical eonveyer located between the horizontal coi'iveyers, substantially as shown and described.
