LOADING APPLIANCE.

Application filed November 10, 1921. Serial No. 514,125.

To all whom, it concern:

Be it known thatI, CHARLES L. TALBOT, a

citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois, have invented certain new and.

useful Improvements in;,Loading Applinces, of which the following is a specificatlOILI' My invention relates to street cleaning and other similar appliances and concerns more particularly an improved and novel style of apparatus for removing snow and the like from the street and loading it upon a truck to be carried away for disposal.

The new structure is intended toprovide a complete snow handling machine, but its essential parts may be made as an accessory for street cleaners which remove the ordinary dirt and filth from the pavements, thus giving to such cleaners a capacity 'for operating efficiently throughout the entire year. The prime purpose and leading object of my invention is the provision of such a structure which is simple in construction, which operates efficiently, which isunlikely to become injured or damaged in ordinary service, which. is easily operated and controlled, and which may be produced and maintained in proper condition at relatively small expense. i

To the attainment of, this and other desirable ends, the scoop associated with the elevating conveyor is located at the frontend of the motor driven vehicle whereby the appliance may be driven over a pavement and remove the snow ahead of it and whereby it may be readily brought to a pile of. snow and cause'the'latter to be removed, elevated, and delivered into a waiting truck.

It is not necessary that the truck back up to the snow loader, but rather it may be drawn up to the side of the latter and receive its load; in fact, the loader is designed to deliver the snow to either side thereof thus permitting the loading of trucks from both sides.-

In order that those skilled in this art may have a full and complete understandmg of the invention and its several advantages, in the accompanying drawings forming a part of this specification I have illustrated apreferred embodiment of such invention and like reference characters have been used throughout the several views to apply to the same parts of the mechanism.

plete structure;

Figure 2 is a plan view of the same;

Figure 3 is an enlarged vertical section on line 33 of F igure 1; A

Figure 4 is a fragmentary detail of a portion of the transverse conveyor;

Figures 5, 6, and 7 are details of the elevating conveyor; and

Figures 8 and 9 are details of the structure for adjusting the cross conveyor to cause it to be operative at either side of the appliance. I

It is intended, although the invention is not so limited or restricted, to use a street cleaner of substantially the type and style set forth in United States Patent 1,239,293, J. M. Murphy, Street Sweeping Machine, granted September 4, 19-17 and to so modify it or removesome of its parts whereby it may receive and operate the snow handling attachment or accessory.

Accordingly, the appliance of the present application includes a mainframe 20, two rubber-tired front carrying wheels 21, 21, a rear similarly tired steering wheel 22, steering mechanism 23,.a steering wheel 24,

.an internal combustion motor 25 associated with the usual gearing contained in a housing or gear box 2 a drive shaft 27 equipped with sprocket-w eels and chains 28 for rotating the drive wheels 21, 21, a seat 29 for the operator, and a dirt receptacle or storage compartment 30 substantially like the corresponding parts of the machine of the patent referred to, the other elements of the street sweeper being removed to accommodate and operate the snow handling structure about to be described in detail.

A suitably-shaped, upright. frame, denominated as a whole 31, is removably or demountably bolted or otherwise conveniently fastened to the center portion of the mainframe 20, and supported in part by such supplemental or auxiliary frame and in part by the dirt receptacle 30, to which it may be fastened in any convenient manner, there stretches of endless sprocket chains 36, 37,

which at intervals have suitable lugs or ears 38to which are fastened transverse blades 39, 39 each strengthened and stiflened by a truss-rod 40 appropriately connected to the end portions of the blades and equipped with central struts 41.

At their upper ends these chains encircle sprocket-wheels 42 on a shaft mounted in bearings carried by the frame 31, and at their lower ends near the ground such chains pass around similar spaced sprocket wheels 43 on a shaft 44- revolubly mounted in a pair of arms 45, 45 fulcrumed on the inclined frame 3% at 46 with weights 47 on their other ends, such construction permitting of anupward movement of the shaft and sprocket-wheels under abnormal conditions hereinafter referred to.

The shaft' of the upper sprocket wheels is rotated from the power shaft 27 through suitable sprocket-wheel and chain connecside plates tions 110 and 111 and an intermediate cross shaft 112.

The sloping lower members 48, 48 of the frame 32 have cross boards 49 secured thereto, and to prevent wear these are covered with sheet-metal 50, the edge portions of which are bent upwardly or flare outwardly at ,51'b'eneath the lower tracks 34 as is indicated in Figure 5.

To confine the snow above such tracks and prevent its spilling, as it is pushed upwardly by the traveling blades 39, opposite metal 52, 52 are fastened to the framework, whereby the plates 50 and 51 in com bination with the plates 52 conjointly form an inclinedor sloping trough for the accommodation of the upwardly traveling snow. I v

At the bottom of the sloping or inclined frame'32 and below the lower end of the bladed sprocket-chains, I provide a hinged scoop 53 having abottom wall 54 and flaring side walls 55 shown most clearly in Figure 2.

Such scoop or shovel is hinged at 56 on the lower end of the inclined frame and it has. two arms 57, 57, one at each side, extended beyond the hinge pins and supplied with adjustable weights 58, 58.

To adjust or-govern the position of such scoop or shovel, it is equipped with an outstanding pin 59 just above'one arm of a bell-crank 60 fulcrumed at 56, the other arm being connected by a link 61 to another bellcrank 62 pivoted on the frame 32 and connected by a link or rod 63 to an operating or controlling handle or lever 64 fulcrumed on the frame 31 in convenient position to be actuated by the occupant of seat 29.

The scoop normally overbalances the action of the weights and its position can be easily regulated by manual actuation of the handle, any suitable locking means, not

blades to efficiently and effectively perform I the function specified.

Such blades also may be used to wear away or break down a pile of snow into the scoop from which it is carried up as indicated.

On the frame 31 a cross conveyor is mounted and so constructed that it may deliver its load to either side of the appliance.

Such conveyor or carrier comprises a pair of spaced, endless sprocket-chains 70, 71, passing around sprocket- wheels 72 and 73 mounted onsliafts 74 and 75 supported in bearings 76 and 77 on the opposite ends of an adjustable frame 7 8 adapted to'slide during its adjustment crosswise the framework 31 on a plurality of anti-friction rollers 79.

The upper stretches of these companion chains are driven by a pair of sprocketwheels 80, one for eachchain, located below the upper portion of the chain as shown in Figure 3, and in cooperative relation therewith, whereby the turning of the sprocket wheels causes the usual travel of the chains in either direction depending upon the control mechanism described below.

To hold such portions of the chains down in proper position with relation to the driving sprocket-wheels, 81, 81 supported on the frame 31 as depicted in Figure 3.

The two sprocket wheels 80 are on a suitably-supported shaft 82 equipped with a sprocket wheel 83 driven by a sprocketchain 84 operated by a sprocket-wheel 85 on a shaft 86 supplied with a friction cone 87 adapted to be rotated by either one of a pair of similar cones 88 and 89 slidable on and rotated by a shaft 9 driven from the shaft 27 through a sprocket chain 91 co-acting with sprocket-wheels on the two shafts in the usual way.

I employ idler rollers The friction cones 88 and 89 are adapted to he slid along on shaft 90- by an enclosing frame 92 operated by a lever handle 93 connected thereto by a link 94.

Thus by means of such controlling handle, the direction of travel of the horizontal chains may be reversed at will.

In order to constitute such chains as a belt conveyor to carry. the snow or other material crosswise the ,machine after receiving it from the elevator, many of the links of the chains are provided with lugs or ears 95 to which the marginal portions of flexible belt 96 are fastened, the lading, of course, being supported and transported by the belt pro er, the chains on opposite sides thereof constituting the driving means for the belt.

To enable the operator to shift, or modify the position of the transverse frame and such belt conveyor carried thereby, to discharge its load at will at either side of the appliance, I provide the following specified cooperating lnstrumentalities.

- a waiting truck, as indicated conventionally On the supplemental frame 31, I mount a shaft 100 and equip it with a turn wheel 101 whereby the shaft may be manually operated.

On the shaft I provide a drum 102 associated with two cables 103 and 104 each having an end fastened to the drum and their other ends secured to-the opposite end portions of the sliding frame 78, whereby by turning the handle or wheel 101 one cable will be wound up and the other paid out from the drum causing a corresponding sliding movement of the frame and the conveyor which it carries.

Turning the wheel and shaft in the other direction will, of course, cause the sliding ofthe frame and its conveyor in the opposite direction, thus enabling the operator to deliver the load to either side of the ma.- chine as he chooses. If desired, two drums 102 may be employed on the shaft 100 and two sets of cables used, one for each side of the slidable or reciprocatory frame.

In operation the machine is caused to travel along the pavement or it may be advanced to a pile of snow, and in either case the scoop in combination with theblades on the elevator chains causes the upward travel of the snow in the inclined chute, from which it is automatically delivered on to the transverse conveyor apron which transports it sidewise and delivers it over its end into in dotted lines in Figure 3.

The position of the scoop for most effective work is controllable by the handle or lever 64 and the scoop is free to rise if it encounters an obstruction, being automatically returned to adjusted position by reason of the fact that'its weight overbalances the action of the Weights 58,: as soon as this action is permitted.

In case any of the blades 39 in traveling around the lower sprocket wheels engage any large hard and resisting object such as a rock or piece of ice, such sprocket-wheels and their mounting yield upwardly by reason of the weighted structure employed and prevent breakage of any of the parts.

It will be seen, therefore, that the appliance described in detail above and illustrated in the drawings fulfills all of thespecified advantages and overcomes a need foranapparatus of the structure and operating'in the manner indicated.

The invention is not limited and restricted to the precise and exact detailsof construction since it may be modified within coinparatively wide limits without departure from the heart and essence of the invention and without the sacrifice of any-of its substantial benefits and advantages.
