Referring now more specifically to the accompanying drawings; wherein like numerals r indicate' similar part's throughout the several views; I 0 indicates afra-me which is generally-rectangular in-shape and will preferably'be constructedofside and end members i2 and i l respectively, and which provides or constitutes an open supporting structure, which-is-providedwith'the cus tomary rear-axles and wheels indicated at; and With-front casters I 8 swivelled' upon the laterally-extending frame member 20. A bed indi cated generally atZZ, and also constructed of generallyrectangular shape and provided with the: customary side and" end members; is pivota-ll'y" connected" as at 2 -l-fupon brackets 25 secured to the-side: members, l2 ofthe frame H1. The IJiVOt'f 24-j-is locatedatoneend ofthe' bed 22, and ispref erably disposed adjacent the casters l8: The" rear 01" the bedZ'Z-isprovided-with a hydraulic "jackoperatingmeans indicated generally at 28 and which isoperatively positioned between the frame It} and-the bed*22' forthe purpose of-raising'the rearward'endof the bed 22'and' causing the-bed to pivot about thefulcrum point 24- for a purpose-to be laterset forth; This jack 28, as seenin Figure 5, may be of any suitabletype; and for convenienceisshown as being hand operated; being-provided with anoperating crank '30;
As shown'best in Figures-1 and-6, the frame-or chassis i i-is provided at its" forward end-'witha rigidly mounted vertically extending supporting structureconsisting-of parallel columns- 32 suitably cross=braced 1 orreinforced as at 3-4 and i provided at" their upper portions with a reinforcing cross-ban36z Inclined at a convenient angle relative'to theframe- H and of'sufficient length to have its lower portion terminate preferably below the bed 22 and frame l0; and'with its upper end adapted" to overhangthe truck portion 38--of any suitable type oftruc-ks or the like, is an elevator framework indicat'ed'generallyat 4G and consisting' of'a pair'of" side members 52; provided with thecustomary end type of suitable cross-bracing not shown; and adapted to be rigidly supported by-the-above mentioned columns 32 and by the frame It). A conveyor chain ill-of the well known chain: or web or belt type, and provided with laterally-extending" panels or" buckets 56, is suit-- ably entrained oven-a pair of" axlest and 53 mounted at 'oppos-ite ends ofthe-conveyorlfi. As'
shown more clearly in Figures 1 and 8, the shafts 48 and 58 may be provided at opposite ends thereof with sprockets or drive wheels 52, which serve to rotate the'conveyor in endless manner as well known in the art.
A source of power, such as an internal combustion engine indicated at 58, and having a fuel supply tank 58, all as shown in Figure 1, is mounted in any suitable manner upon the bed 22, and connected as by a belt or chain drive 58 (see Figure with the shaft or axle 68 of a rotary impeller indicated at 62 and which is provided with radiating vanes 64. As shown best in Figure 1, a belt 66 connects a driving sprocket 88 upon the axle 68 of the impeller with the above mentioned sprocket wheels 52 on the conveyor drive shaft 48. Thus, whenever the rotary impeller 82 is operated by the engine 54, the conveyor 48 is simultaneously actuated for a purpos to be subsequently described. Attention is now directed to Figure 8, wherein it will be seen that the impeller casing is provided with a lip or scoop 18 at its lower end, this lip being disposed in a horizontal plane parallel to the surface of th road which it is desired to scrape or clear of snow or the like. This lip extends forwardly, and constitutes an inlet opening or means for the impeller 62, wherein the rotating vanes 84% serve to sweep into the impeller casing snow or like material as the apparatus is moved forward. The impeller casing extends closely about the rotor vanes 64, and terminates at the upper end, in a portion I2 constituting a discharge guide means which extends tangentially of the circular travel of the outer periphery of vanes 84, and disposed in a position to throw or discharge the snow or other material carried by the rotating vanes 64, in a direction to imping upon the upper surface of the conveyor 48. It will thus be seen, that as the apparatus moves forward, snow is scooped up upon the lipid, delivered into the impeller 62, and centrifugally'hurled therefrom under the guidance of the discharge guide means 12 onto the conveyor 48, whereby the material is elevated and discharged from the end of the conveyor into the body 38 of the towing truck.
In order to properly tension the conveyor chain 44 and maintain the latter in the desired degree of tightness to compensate for wear or the like, the forward axle or shaft 58 is mounted in adjustable bearings, and as shown in Figure 4, is adjustable longitudinally of the conveyor casing or side members 42, by means of an adjusting screw I4 which is threaded through the depending end of a bracket I6 mounted in any suitable manner, upon the side member 42 of the conveyor, at the upper end thereof, and is retained in adjusted position as by a lock nut 18. Fhe rear end of the screw threaded member E l, carries a bearing for the shaft 58 and thereby serves to longitudinally move the same to thus tighten or loosen the chain 44.
In accordance with this invention, means is provided for collecting and supplying the snow or other material to be removed and discharging the same adjacent the inlet means or lip of the casing of the impeller 82. For this purpose, a bracket 80 is secured upon a side member I2 of the frame If], and this bracket rotatably supports and constitutes a journal bearing for the vertically extending support shaft 82, which at its upper end is provided with an outwardly extending arm 84 extending in parallelism to a laterally extending blade 86 vertically slidable upon the lower end of the shaft with a. head portion 88 upon which is mounted a Windlass or crank 90 for operating a cable 92 entrained over the arm 84 and connected with the blade 86. By this mechanism, it will be seen that the Windlass 98 and cable 92 may be operated to raise or lower the blade 86 upon the lower end of the shaft 82; and that rotation of the blade 86 and arm 84, is effected in unison by rotation of the shaft 82 in its bearing 88 in a manner to be now set forth. At its lower end, the blade is provided with a removable or replaceable knife edge 94 for the purpose of scraping encrustations or deposits of snow or the like from the surface to be cleaned.
At its outer extremity, an anti-friction roller 96 is journaled for vertical rotation in laterally projecting lugs 98 of the blade 86. A chain I88 is provided for limiting the amount of movement of the blade 85 about the axis of the shaft 82, and thereby determine the width of the surface from which snow is to be cleared by the device. As so far described, it will be seen that upon forward travel of the device, the scraping edge 94 of the laterally extending arm 88 feeds and guides snow or other material along the blade and into the inlet end or lip Id of the impeller. The edge 86 of the blade 88 may be raised or lowered by means of the mechanism attached to the cable 92, while the blade may be opened laterally 0f the frame I8 by suitable manipulation of the chain I80. The roller 96 serves to roll against lateral obstructions such as the curb of a street, and thereby limits the opening of the blade 86 by such contact as well as preventing injury to the edge portion of the blade. In this use of the device, the chain I08 further serves as a means for adjustably regulating the amount of opening movement which itois desired to impart to the blade 86.
Attention is next directed specifically to Figure 6, wherein it will be seen that a signalling system consisting of electric lights I82 of any desired color for the emission of any desired signal or for lighting of the device together with a horn indicated at I84, are mounted upon the pillars 32. These signalling devices are under the control of the operator of the apparatus in order to contribute to the safety of the operators thereof and of other persons using the road. Attention is next directed to the coupling means for attaching the snow loader to a truck or the like for towing the same. As shown in Figures 1 and "I, the transverse bar 28 has a pair of eye bolts I86 extending through suitable apertures in the bar 20 with spring means I08 and adjusting nuts II8 being provided thereon as shown in Figure '7. The eye bolt portions H2 are adapted to loosely receive and retain a transverse bar or pin I14 upon which is formed and from which forwardly extends a plate I I6 terminating in a bar II8, which is provided with a suitable aperture I28 and slot I22. The bar H8 is preferably in the form of a flattened sleeve and slidably receives therein a strap or bar I24, whose forward extremity is provided with a downwardly extending hook I26 adapted for detachable connection with a suitable draw bar connection secured upon the frame of the truck Whose body portion is indicated at 38 in Figure 1. The strap I24 is suitably apertured as at I28, and is detachably retained within the sleeve portion I I8 as by means of a fastening pin I48 engageable through aligned apertures I28 and I28. By this arrangement, the snow loader is detachably coupled to the rear of a towing truck, and the spring means I08 provide a yieldable cushioning means for towing the apparatus. The latch pin I40 constitutes ready means, operable in any suitable manner, for quickly lengthening or shortening the bar I24 by adjusting the bar I24 longitudinally of the sleeve H8 or even disengaging these telescoping members as desired.
In order to permit the operator to release the bar I24 from the drawbar of the towing machine 38 the following mechanism is, employed. A flexible linkage or cable I42 has one end secured to an eye-bolt I44 on the sleeve H8 and is entrained over a guide I46 attached to the frame member 34, and thence passes through a protective pipe or tube I48 secured suitably beneath the frame I0, and at its other end is connected to an operating lever I52 pivoted as at I54 to the frame I0. By manipulation of lever I52 the operator may without leaving his post upon the device behind the engine 54, raise the tongue or bar I24 to disengage the hook I26 coupled relation to the tractor vehicle.
It is to be distinctly understood that the drawings and accompanying description are to be regarded as purely illustrative of the principles of the invention only, and that any suitable modifications may be employed falling within the scope of the appended claims.
