BRICK-HANDLING TRUCK.

SPECIFICATION forming part of Letters Patent No. 753,901, dated March 8, 1904.

Application ned July 9, 190s. serial No. 164,879. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM MILLER, a citizen of the United States, residing at Thomasville, in the county of Thomas and State of Georgia, have invented a new and useful Brick-Handling Truck, of which the following is a specification.V

My invention relates to brick-trucks, and is especially directed to the class of trucks which are employed in brick-yards for transferring the bricks from the machine to the dryingshed and thence to the kiln, and has for its objects to produce a device of this character of simple construction` which'will be eflicient in operation and one which may be readily manipulated for raising the brick pallets from or lowering them onto the receiving-racks.

Tothese ends the invention comprises the novel details of construction and combination of parts more fully hereinafter described.

' In the accompanying drawings,Figure lis a diagrammatic view illustrating the yard system. Fig. 2 is a vertical sectional elevation showing conventionally the handling ofthe pallets at the loading-point on the line 2 2 of Fig. 1. Fig. 3 is a vertical longitudinal sectional elevation illustrating the truck depositing loaded pallets in the drying-shed. Fig. 4 is a side elevation of my improved truck, showing in dotted lines the position of the parts .when the supplemental frame is elevated.

Fig-5 is a vertical transverse section on the line 5 5 of Fig. 4. Fig. 6 is asectional detail on the line 6 6 of Fig. 4. Fig. 7 is a similar View on the line 7 7. Fig. 8 is a detail view of one of the bearing-plates.

Referring to the drawings, 1 indicates a brick-machine, 2 a kiln,and 3 a drying-shed.

4 isa main track extending between the machine and kiln, and 5 are supplemental tracks extending therefrom to the drying-shed.

6 is an endless belt which travels from the brick-machine between a pair of supportingracks 7, which sustain'the pallets 'to' be loaded and which consist each of a pair of spaced parallel horizontal bars 8, sustained in elevation by vertical standards 9. These racks are adapted to support the pallets 10 while being loaded with green bricks conveyed from the machine by the endless belt 6 and are suiiithosejustl described.

ciently elevated to permit of a truck 11, more fully hereinafter described, passing beneath the said pallets, as shownin Fig. 2, the trucks being arranged to travel upon branch tracks disposed between the spaced bars of the racks.

The main track 4 is sunken below the branch tracks and secondary tracks 5 a distance equal Y.

to the height of a transfer car 12, which travels upon said main line and which is adapted to receive one of the trucks 11 carrying a load and transfer it from the loading-point adjacent to the machine to the shed 3, where -the truck is run off onto one of the supplemental tracks for conveying the bricks into the shed and depositing them upon-suitable supporting-racks similar in construction, to ,This transfer-car also serves to take the pallet-carrying trucks from the drying-shed to the kiln for depositing the pallets in the latter. j

My improved truck, which is killustrated more clearly in Figs. 4 to 7, comprises, essentially, a pair of axles 13, provided with sup- ,porting-Wheels 14, a main -frame 15, sustained i upon the axles, and a supplemental frame 16,

movably connected with the main frame for elevation or depression relative thereto. The

\ wheels 14 are mounted for rotation upon the axles 13, .and the latter carry at each end outside of the wheels a head 17, from which arises a pair of oppositely-curved standards 18, to which latter the parallel side bars 19 of the main frame 15 are bolted or otherwise secured.

yThe side bars 19Yeach consist of a suitable length of angle-ironof inverted-L shape in crosssection and disposed with its upper horizontal flange'2() extending outward, said side bars being connected by tubular Vend bars 21,

the outer ends of which latter .are threaded and tapped into internally-threaded bearings 22, formed upon bearing-plates 23, bolted or otherwise secured to the inner faces of the side bars, thus producing a strong and durable and at the same time simply-constructed frame. The supplemental frame 16 .comprisesa pair of parallel side bars 24, each consisting of a suitable length of angle-iron and tubular endconnecting bars 25, havingtheir ends tapped into bearings 26, formedupon plates 27, bolted.

or otherwise secured to the inner faces ofthe IOO side bars, as in the instance of the main frame just described, the two frames being, in fact, identical in construction and the side bars of the supplemental frame being of inverted-L .shape in cross-section and disposed with their horizontal flanges 28 extending outward. The supplemental frame is of a width somewhat less than the width of the main frame,whereby it may be depressed to a position within the latter, as hereinafter explained. The supplemental frame is movably connected with the main frame by means of links 29, each consisting of a suitable length of strap-iron bolted at its ends to the side bars of the main and supplemental frames, respectively, the attaching bolts serving as trunnions upon which the links swing during the movements of the supplemental frame. Any suitable number of links may be employed; but I preferably employ three links to each side, disposed one adjacent to each end of the frame and one at its longitudinal center, and attach said links, with their upper ends disposed upon the outer face of the side bar 24 and their lower ends disposed upon the inner face of side bar 19. Attached adjacent to the longitudinal center of each side bar 19 is a stop member 30, consisting of a short section of the angle-iron of L shape in cross-section, having its lower horizontal Bange extended outward and bolted to the outwardly-extending iiange 2O of the side bar and its vertical iiange extending upward from said bar in position for the horizontal flange 28 of side bar 24 to contact therewith and limit the downward movement of the supplemental frame. This stop 30 is so positioned relatively to the central connecting-link 29 that when the supplemental frame is elevated said link will swing slightly past center and then contact with the stop, thus maintaining the frame in its elevated position, as will be readily understood. Thus it will be seen that the stop 30 serves the twofold function of limiting the downward movement of the supplemental frame and of acting, in conjunction with said central link 29, to maintain the frame in its elevated position.

In practice the truck 11, with its supplemental frame depressed, will be of the proper height to pass freely beneath the pallets 10 when sustained upon the racks 7, which latter are of course of a uniform height at the machine in the drying-shed and in the kiln and are, with said frame depressed, run under the pallets which are to be transferred. The frame 17 is then elevated by swinging the same upward upon the links 29, as indicated by dotted lines in Fig. 4, in which position of the parts the frame will elevate the pallets sufficiently to clear the racks 8, as indicated more clearly in Fig. 2, and the links will swing slightly past the center and the central link contact with stop 30, as above explained, thus maintaining the frame in its elevated position. The loaded truck is then moved onto transfer-car 12 and conveyed to the desired point and then run off said car onto, say, sup plemental rails 5 for depositing the pallets in the shed. When the truck has reached the desired point in the shed, the frame 16 is shoved forward sufciently to swing the links forward of the center, when the frame will drop by gravity and deposit the pallets upon the supporting-racks in the shed, as will be readily understood, the stop 30 serving to limit the downward movement of the frame and the force generated by the descent of the load being sufficient to run the car backward from beneath the deposited pallet.

From the foregoing it will be seen that I produce a truck of simple construction which may be readily manipulated, one which in practice will admirably perform its functions, one in which two cars may be loaded'simultaneously, owing to the fact that the endless belt from the brick-machine runs between them, and one in which the need for turntables or the like in transferring the cars from one part of the system to another is entirely obviated. In attaining these ends I do not limit myself to the precise details herein shown anddescribed, inasmuch as minor changes may be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim isl. In a device of the class described, the combination with the axles and supportingwheels, of a main frame carried thereby, a vertically-movable supplemental frame, connecting-links pivoted to the main and supplemental frames, and a stop attached to the side bar of one of the frames and projecting' beyond the same for engagement by the other frame to limit the downward movement of the supplemental frame, said stop being adapted for engagement by one of the links 'for maintaining the supplemental frame in elevated position.

2. In a device of the class described, the combination with the axles and supportingwheels, of a main frame carried thereby, a vertically-movable supplemental frame comprising side bars having horizontal flanges, connecting-links pivoted to the main and supplemental frames, and a stop attached to the side bar of the lower frame and projecting above the same for engagement by the horizontal flange of the supplemental frame to limit the downward movement of the latter, said stop being adapted for engagement by one of the links for maintaining the supplemental frame in elevated position.

In testimony that I claim the foregoing as my own I have hereto'aflixed my signature in the presence of two witnesses.

WILLIAM MILLER.
