SNOW-REMOVING APPARATUS.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed November 12, 1913. Serial No. 800,576.

Massachusetts, have invented certain new and useful Improvements in Snow-Removing Apparatus, of which the'following. is a full, clear, and exact specification.

This invention relates to snow plows, and has for its ob ect the provision of apparatus for removing the snow from the streets and carrying it away in addition to clearing a track or passageway. i

Heretofore' the function of a snow plow has. been to displace the snow from one part of a street orsidewalk to another part adjacentthereto, the snow thus piled up along the edge of the'cleared part being subse quently removed by wagons into which it is loaded by hand shovels.

My present invention contemplates the clearing of an entire street or sidewalk, if

-. desired, and the removal or transportation of the snow at the same time. Thus, my improved apparatus is adapted and designed to carry off the snow clearedfrom the street or sidewalk in addition to clearing a pas sageway, and to perform both operations successively and continuously, whereby a single trip of my apparatus down a street or sidewalk will result in the complete removal of substantially. all the snow which has fallen, at the time said apparatus passes.

The apparatus is equally well adapted for use on afline of railway for clearing between and adjacent the tracks.

Another object of the'invention is to remove the ice with the snow, and to this end means are provided for releasing or breaking away the ice from the pavement in advance of the plow.

A further object is to provide means for moving the snow taken up by the ap aratus,

' from one conveyance to ani'jther and for discharging the snow frhin the conveyance into which it is finally stored, when a suitable dumping place is reached.

Fhe invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification, and then more .pecifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used throughi out .the several views to designate corregear spending parts Figure 1 is a side elevation of snow removing apparatus constructed in accordance with my invention, the lateral guides being removed to disclose the opening in the side of the car into which the snow is guided and from which it is raised by the rotary scoop. Fig. 2 is a sectional plan showing the ice picks arranged in front of the plow, the lateral guide plates or strips, and the rotary scoop. Fig. 3 is a central vertical longitudinal section through the snow removing apparatus as illustrated in Fig. 1..Fig. l is an enlarged detailed cross section of the rotary scoop in connection with the cam for operating the devices which positively clear or discharge the snow from .the scoops. Fig. 5 is a detailed side .view of the cam just mentioned.

The mechanism or apparatus for taking up the snow is mounted on the snow plow,

or rather on the car or vehicle having the plow on its front end. This car or vehicle is illustrated in Figs. 1, 2 and 3, and comprises a body 12 generally rectangular in form with sides which reach down near to the surface of the street or roadway, as at 13, Fig. 1. The front end of this vehicle or car is equipped with a.snow plow 14s of suitable form for throwing the snow to either side of the car.

Projecting through slots or openings 15 in the front of-the car are a plurality of ice picks 16 which are mounted on a crank shaft 17, F igs. 2 and '3, by which they are adapted to be reciprocated. In front and a little below the crank shaft there is a cam shaft 18 having cums 19 adapted to engage the re spective picks and raise thcirouter ends as they are being moved forward by the crank shaft. The crank shaft and the cam shaft are both driven by a suitable motor 20, Fig. 3, by means of the sprocket chain 21 and ){L the two shafts so that they arerotated in the same direction. It will be understood that alternate cranks extend in opposite direc- -,to fall at the end of such ouhvard or forward movement. Springs J3 may be used to insure the proper dropping of said picks when the cams pass from below them or for the latter being interposed between IEIA increasing the force of the blow delivered by the. picks in falling. By means of these picks it will-be seen that the ice which usually forms under the snow will. be loosened or chopped from the pavement in advance of the plow, so that said ice will be thrown to either side with the snow as the plow advances.

Openings Z-t are provided inceach side of the car, preferably about centrally thereof and opposite each other. To the rear edge of .each of said openings there is hinged a guide plate or strip er-rtemlin g, outward and forward at a desired angle to a point in advance of the plow. 'lhcsc guide strips arr adjustably connected to the sides of the car by chains 2d. by means of which the angle thereof with respect to the car may be varied so as to cover the entire width of the street, if desired. As a further means of accomplishing this object, the strips may be each made in two or more sections adjustably connected together at 27, whereby they may be lengthened when necessary to cover wide streets. As will be obvious the guide strips25 direct the snow into the openings 2t in tlie sides of the. car. that is to say the snow w ;h has been throwr by the plow from in front of the car as well as the snow lying at either side of the said car.

The. openings 24 lead to a chamber 28 in which the rotary scoop 2: is arranged. This chamber 28 has a curved cover 30 extending over the 'lo wa rd half thereof, while the rear half of the top of said chamber is left open. The rotary scoop has a plurality of blades 81 extending substantially radially but somewhat curved to better talrcv up and hold the snow in operation. Said scoop fills the chamber, and the partial cover 30 is arranged just beyond the path of the ends or outer edges of the blades. so that there is no chance of the snow escaping or falling from said scoop as it is being raised. After the snow is raised by the rotary scoop, it discharged through the open portion of the top of the chamber 98 onto a platform 32 in the rear part of the car.

In order to insure the discharge of the snow from the blades of the scoop, 1 provide clearers 333, one of which is hinged to the outer edge of each blade and in one position its closely against the rear face of each blade. The clearers are yieldingly held in this position by springs Set and remain so during the greater portion of the revolution of the scoop. Roller bearings 35, carried by the free edges of the clear'ers 33, are adapted to ride on fixed cams 36 for the purpose of moving said clearers outward as they successively come opposite the partial opening in the top of the chamber 28, see Figs. 3, 4 and 5. These cams 36 are of such shape as to not only throw the cleaners outward to a position where they occupy substantially one-quarter of the line of travel of the outer edges of the blades when said blades successively come to the margin of the opening, in the top of the chamber, but

also hold said clcurers out in that position until their respective blades reach the level of the platform 32', when the cam permits the springs 3-1- to quickly draw them in again so as to leave their respective blades unobstructed when their turns come for taking up the snow. It will thus be seen that as each blade of the rotary scoop reaches a position opposite the opening in the top of the chamber the snow which has been raised thereby is positively discharged on to the platform 32 by its clears working on the cam 30.

The rotary scoop may bi: driven by a train of gears 37 from a motor 558. Also driven from said train of are two crank shafts 39 and .0 arranged above the scoop. The crank shaft 39 attached to the bracket 41 of the transverse plunger or pusher 4&1- which is adapted to slide upon the platform 1-52. The crank of the shaft to is arranged below the bracket ti and is adapted to engage said bracket for raising the plunger r: at proper intervals. As shown in 3, the shafts39 and it) are preferably geared to turn in the same direction and atthe same speed. The cranks of said shafts preferably extend in substantially the same direction, so that they turn in unison. The gearing from the motor 38 to the shafts 3S and it and to the rotary scoop is so arranged and proportioned as to cause one retlpl'lit'iillOll of the plunger during each quarter revolution of the scoop. the forward movement of said plunger beginning when each blade of the scoop reaches the edge of the opcnin in. the top of the chamber as shown in Fig. 3. (if course, if the rotary scoop had a greater or less number of blades, the plunger would be made to reciprocate once during the travel of each blade across the opening, in the top of the chamber in which said scoop is mounted. the size of said opening being varied to correspond to the distance between the outer edges of adjacent blades.

By reason of the arrangement of the crank shafts 39 and i l. above described, the plunglcr l2 will be moved forward along and in contact with the platform, but as it is drawn rearward again, the crank on the shaft tO will raise said plunger, thereby carrying it over the snow which has accumulated on the forward end of the platform. The result is that after each reciprmzation of the plunger the same is brought back to the position shown in Fig. 3 with some of the snow behind it to be pushed back on its next recipria-ation. it will thus be seen that as my snow removing apparatus is moved forward in operation the. snow from the menses Whole Width of the street or roadway is directed into the chamber 28 from whence it is 'a-ised or conveyed by the rotary scoop 'to the platform 3:2, and the snow thus deposited onthe platform is pushed back along the same to the rear end of the car which may beclosed, if desired, by a door 43.
