SNOWPLOW.

Application filed April 20, 1928. Serial No. 271,538.

The present invention relates to a snow plow and has for its primary object to provide a structure capable of being mounted to the front of the tractor and propelled thereby and -having a driving connection from the pulley of the tractor so that the operating mechanism in the plow may be run at a uniform rate of speed regardless as to how fast the tractor is moving.

Another very important object of the invention resides in the provision of a snow plow of this nature having a transversely operating auger conveyor and an velevator leading therefrom in combination with rotary choppers in advance of the conveyor to break up the snow and ice in sufficiently small pieces to be taken care of by the auger conveyor without any tendency to clog the same. j

A still further very .important object of the invention resides in the provision of ice choppers which are easy to assemble and disassemble in relation to their operating shafts. f

Another important feature of the invention resides in means for elevating the plow in respect to the tractor,.said means being operable in a convenient manner by the driver of the tractor. r 1

A still further very important object of the invention resides in the provision of a snow plow of this nature which is simple in its construction, strong and durable, thoroughly eflicient and reliable in operation, not 35 likely to easily become out of order and otherwise well adapted to the purpose for which it is designed.

With the above and numerous-other objects in view as willv appear as the descrip- 40 tion proceeds, the invention resides in certain novel, features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed. l

In the drawings:

Figure 1 is a side elevation of a snow plow embodying the features of my invention showing the same mounted at the front of the tractor, p Figure 2 is a fragmentary plan view of the attachment frame7 l l Figure 3 is a detail sectional 'View through a portion thereof,

Figure t is anoenlarged side elevation of 55 the plow showing a cover plate removed.

Figure 5 is a fragmentary detail Vperspeczontal Vtransverse conveyor casing the rear Y wall ofwhich is substantially semi-cylindrical as indicated at 5 and merges into a flat bottom wall 6 with a scraper blade 7 secured thereto. The upper edge of the rear wall 5 merges into a wall 8 which extendsy up-l` wardly` and inclines slightly rearwardly. The front of this horizontal transverse conveyor casing is open. An auger 9 is .journaled in the conveyor casing and is con- .structed so that the spiral at one endy is more pronounced as is indicated to advantage in Figure 8. Side plates lO'areprovide'd at the ends of the vtransverse horizontal conveyor casing and extend vertically and longitudinally of the apparatus.

These plates taper to points at their front f ends as is indicated to advantage in Figures land 6 and in these pointsis journaled a shaft 11 formed with longitudinally eX- tending channels 12. As is indicated to advantage in Figurek 8 ythe shaft l1 extends through longitudinal slots .14 in the plates 10 and is journaled in bearings 15 adjustable forwardly and rearwardly by screws 16. On the shaft 11 there are detachably mounted a plurality of clog breakers 17 of elongated curved construction as is indicated to advantage in Figures l and 2. v

rl`heseV clog breakers are held on the shaft by means of tap plates 18 which are secured tothe clog breakers by bolts 19 or in any other detachable manner. Both the clog breakers and the tap plates have projections 2O to lit in the channel 12 so asto key the clog breakers onthe shaft 11.

yA cylindrical elevator casing 22 communi- Cates through an opening-23 in one end plate l10 with the horizontal conveyor casing ,and inclines upwardly and rearwardly. The

end wall 10 is provided with walls 23 to form a casing with a removable cover 24. An outlet trough 25 is provided on ythe upper end of the elevator casing 22 and depends 4downwardly to one side. An auger 26 is rotatable in the casing 22 for elevating the snow which is delivered through the opening 23 into the bottom of the casing 22 so that the snow may be delivered into a wagon running alongside the apparatus.

A U-shaped frame 27 is fastened to the frame of the tractor T. The ends of the frame 27 are straddling the tractor frame and bolted or otherwise secured theretoso that the bight of the attachment frame is disposed in front of the tractor frame. A pair of rods 28 are pivoted to the frame 27 one on each side thereof as at 29 and are pivoted as at 30 to the sides of the plow apparatus. An arm 31 is secured to the horizontal conveyor casing and inclines upwardly and rearwardly and terminates in a substantial horizontal extension 32. Bearings 33 are fixed on the extension 32 and have journaled therein a shaft 34 with a` worm 35 thereon meshing with a worm gear 36 fixed on a screw shaft 37 which extends through an opening 38 in the extension 32 and is threaded in a cross plate 39 on the frame 27.

This cross plate 39 is bolted to the frame as at 40 and is provided with openings 41 to accommodate different sized frames. The pivot means 29 is in the form of a rockable shaft in bearings 42 on the frame 27. A shaft 44 in telescopically associated sections is coupled with the shaft 34 by a universal joint 45. The shaft 44 is coupled by universal point 46 with a shaft 47 journaled in brackets 48 and 49 with a wheel 50 at the upper end thereof.

Obviously by turning the wheel 50 the worm 35 may be actuated for turning the worm gear 36 and the screw shaft 37 thus elevating or moving down the extension 32 and the arm 31.

In this manner, obviously, the plow apparatus may be raised or lowered by swinging about the pivot shaft 29. A shaft 52 is journaled through the plate 10 to the rear of the plate 8 and has a pulley 53 thereon over which is trained a belt 54 also trained about the pulley 55 of the tractor power takeoff. Suitable spring belt tightening means 56 is associated with the belt 54. Particular means herein comprises bracket arms 57 projecting rearwardly from the plate 8 and rockably supporting arms 58 with the roller 59 journaled therein engaging the belt being so urged by springs 60.

A sprocket 61 is i'iXed on one end of the shaftV 52 in the casing 24 and drives the chain 62 which is trained over a sprocket 63 on the end of the shaft 11 in the casing 23. This chain 62 also drives a sprocket 64 by the intermediate portions of its upper and lower runs engaging said sprocket 64. This sprocket 64 is fixed on a shaft 65 to which is fixed a bevel gear 66. The bevel gear 66 meshes with the bevel pinion 67 on a vertical shaft 68 journaled in suitable bearings 69 and having a bevel pinion 70 on the lower end thereof meshing with the bevel pinion 71 on the lower end of the shaft of the auger 26. The shaft of the auger 9 is operatively connected with the shaft 65 by chain and sprocket means 72 with which is associated a suitable chain tightener 73. The chain 62 may obviously be tightened by adjustments 16.

When the tractor T is advancing and the pulley 55 is in operation it will be seen that the clog breakers revolve and break up the snow and ice to proper size to be taken care of by the horizontal conveyor. Snow and ice are brought up by the scraper and caused to engage the auger in the horizontal casing so that the snow is delivered through the opening 23 into the elevator up which it passes and is delivered out through the chute 25 into a wagon progressing alongside of the tractor or into any suitable receptacle or th like.

The plow apparatus may be readily adjusted to the desired height by the operator of the tractor in a convenient manner because of the location of the wheel 50. This plow apparatus will clear a relatively wide path and, therefore, is particularly useful in cleaning snow from the roadway and the like.

It is thought that the construction, opera-u tion and advantages of the invention will now be quite apparent to those skilled in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the ini vention and the above description. It will be apparent that changes in the details of construction, in the size, and combination and arrangement of parts may be resorted to without departing from theA spirit or scope of the invention as hereinafter claimed.
