My invention consists in a new and useful improvement in apparatus for snow removal and isdesigned particularly for operation against snow banks or drifts: and in such conditions of snow removal as that the depth of snow is considerable andthe snow has become tightly packed and. hardened. Such conditions. quite common in places of frequent and long continued snows and exceedingly low temperatures, render use lessordinary snowremoval devices, such: as plows and brushes. My improved device is designed to disintegrate: hard frozen and densely packed snow banks and rapidly remove the loosened snow.
The particularly novel and useful features of my device are the scarifier, in the form of a heavy drum having steel hooks with sharp; points by which the hardened snow is disintegrated, an improved formof concave scoop to supply the g disintegrated snow to the removal mechanism, and: my improved: rotor for ejecting the loosened snow, supplied to it by the concave scoop, through its discharge throatand spout. The particularly novel feature of my improved rotor is the novel scoops with" which it is supplied. These rotor scoops are so designed and mounted thatthey extend forwardly from the'hub of the rotor toward the supply scoop'below the scarifier so-that" the loose snow is guided by the concave scoopinto these rotor scoops; I also provide a shield over the upper half of the forward side of the rotor so that the snow is supplied by the concave scoop only on the lower half of the rotor.
My device: is supplied with its ownmotive power" and I: prefer to use a radial airplane motor attached directly to the rotor and geared to drive the" scarifier. thereby securing adequate power for efficient operation. The device is mounted uponthe-front f a motor truck whereby it may be driven into the snow bank upon which it. is to: operate. It is to be understood of course that 1 it canas equally. well be: mounted upon awheel vehicle for track travel asin cases of clearing railroad or street railway rights of way.
While I have: illustrated in the" drawingsfiled herewith one specific embodimentof my invention", it'- is to be distinctly understood that I do not'corisider-my invention limited to said-specific embodiment-,but: refer for its scope' to -the claims 50 appendedhereto.
In the drawings;
Fig; I is-aside elevation? partly in section. Fig. 2 is a front elevation.
Fig. 3 is an horizontal section on the line 3--3 .55 of Fig. 1.
Fig. 4 is an enlarged rear elevation of one of the rotor scoops with the rotor hub and spider upon the scoop is mounted.
Fig; 5 is a vertical section on the line 5---5' of Fi 4.
Fig. 6 is a vertical section-through the joint of the discharge throat and its spout.
7 is an horizontal section on the line of Fig. 2.
As illustrated in the drawings;- the device is mounted uponthe front ofan automobile truck T by any suitable means attached to the housing I in which is mounted' the motor M for operating the device Mountedupon-the front of the heirs mg I- isthe circular rotor housing 2 provided with the tangential discharge throat 3. Disposed over the upper half of the. front of the housing 2 is the shield 4 and disposed about the lower openhalf of the frontof the housing 2 is the concave scoop 5, and disposed on each side" of the scoop S-a-retheouter' cutting blades 6% Keyed upon the" driving shaft 1 of the motor M, which extends into' the housing 2, is the rotor huh 8 provided. atits forward end with a spider 9- having six spoke's"= l0, peripheral notches H aligned with the spokes l0 and a flange 12 adjacent its periphery. The hub 8 is provided at its rear end-with a" radi'al flang'e rs; Mounted upon the'hub 8*;there are six rotor scoops I4 As these scoops M are identical in construction and mounting; a description of: one will suffice. The scoop llha's' two inwardly extending shanks l5 and Iii bolted tothe spider 9* and the flange l3 respectively. The inner edge l"1- of the scoop between the shanksl 5and l-'6"is received'in 35 oneof the slots H of the's'pider' 9 and abuts the flange l2". Thre'e bra'ce rods IB' extend from the back surfaceof the scoop M to the spider 9i semi-circular edge 20' of the scoop M extends forwardly 'considera of thescoop' l4; slants sharplyrefarwardly' to the that by the novel design'jof the scoop I4; I have scoops, to facilitate a to it. and dis- The. rear edge" IQ of the scoop lf4 extends outwardly at right ang es to the hub a, theouter beyondthe forward end of tlie hub-8 and the forward straight edge 2| forward end of tlie hubllfi 'Ihu'sit willbe seen provided a rotor". w forwardly, projecting the action of the rotor in handling the I'OOS' sriow sllppli e I charging it through Suitably mountedinthe throat {is the rotatahle discharge spout 22- which is provided with circumferential rack 23 and co-acting pinion 24 with hand-wheel 25 for adjusting the spout 22, and latch 26 for locking same in adjusted position.
Suitably pivoted on brackets 21 on the sides of the housing I are the casings 28 extending forwardly between the outer edges of the shield 4 and the outer cutting blades 6. Rotatably mounted in the outer ends of these casings 28 is the drum 29, thereby disposed across the front of the device. This drum 29 is provided upon its periphery with a plurality of curved hooks 30 each terminating in a sharp tooth 3|. I prefer to arrange these hooks 30 in longitudinal rows upon the drum, in staggered formation (see Figs. 2 The drum 29 is provided at each end with a sprocket wheel within one of the casings connected by a chain with a sprocket wheel at the rear end of the casing 28 mounted on the shaft 32 journaled on the brackets 21, and driven by any suitable driving means, such as a chain 33 driven by beveled gears 34 and 35 from the drive shaft 1 of the motor M. j 4 t The casing 28, upon the side of the device upon which is mounted the hand-wheel 25 for the discharge spout 22, has a segmental rack 36 with co-acting pinion 31 on shaft 38 journaled in bracket 39 from the housing I, and having a hand-wheel 40 for adjusting the drum 29 vertically, and latch 4| for locking same in adjusted positions. v I
