FOLDING AND TRANSPORTABLE ELEVATOR.

SPECIFICATICN forming part of Letters Patent No. 766,812, dated August 9, 1904.

Application iiled August 15, 1903. `Serial No. 169,573. (No model.)

To all wlw/omit may concern.-

Beit known that LDAvID B. Coon, of Frankfort, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Folding and Transportable Elevators; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to the ligures of reference marked thereon, which form part of this specification.

The object of my invention is to provide a takedown portable elevator, more particularly adapted for use with stone-Crushers.

In the drawings, Figure 1 shows a side clevation of atruck carrying' a stone-crusher and my improved folding elevator, the elevator being shown in folded position. Fig. 2 shows a partial plan view of the same. Fig. 3 shows a plan view of the elevator-frame. Fig. 4 shows a side view of .one section of the clevater-frame. Fig. 5 shows in plan view the frame which is mounted on the road or carrying wheels 2 3 and besides carrying the elevator hereinafter described carries a stone-Crusher, the iiy-wheels of which areindicated by 4:. Frojecting upwardly and rearwardly from the rear portion of the truck-frame are arms 5, rigidly secured to the truck-frame. Pivoting on journals at 6 at the upper end of the arms is the upper or main section 7 of the elevator-frame. Thelower section 8 ofthe elevator-frame is provided with slides or ways 9 at one side, which run in bearings 10 and 10a on the truck-frame, whereby the lower section of the elevatorframe is permitted to be kmoved up and down in a line somewhat inclined from a perpendicular and in the line of the angle at which the elevator is intended to work. The upper end of the section 8 is connected with the secchain 15 ru ns.

tion 7 at a point somewhat to the rear of the 5o pivot 6-by connecting-rods 1Q. At the upper end the elevator-section 7 carries a shaft 13, provided with a wheel 14, on which the bucket- At the lower end the section 8 is provided with a wheel 16, mounted on a 5 5 shaft 17, on -which the bucket-chain 15 also runs. At suitable intervals on the elevatorframe there are provided rollers, as 18 and 19, which 'support the bucket chain. The lower end of the elevator-section 7 is con- 6o nected by a chain S2() with a reel-shaft 21 on the rear end of the truck-frame, which reclshaft is provided with a crank 22, by means of which it may be operated. For supporting the section 7 in substantially horizontal 65 position overhanging the truck-frame there is provided on the forward portion of the truck-frame the uprights 23. For supporting the bucket-chain when the elevator' is folded there is provided a hanger 24 on the 7o section 7 and a hanger 25, also on the section 7, the latter preferably being removed when the elevator is operated.

To erect the elevator, the operators reel up the chain 2O on the shaft 21, drawing' down 75 the rear end of the section 7 until the section 7 is in a perpendicular position and substantially balancing on the pivot 6. It is then thrown over with the upper end toward the rear, when by letting' out on the chain 20 the 8o elevator-section 7 will swing into the upright inclined position in which it is intended to be used. At the same time that the section 7 is erected the section 8 will be moved downwardly through the medium of the connect- 8 5 ing-rod 12, the lower end, or the carryingwheel on the lowerend, entering a suitable pit which should be previously provided below the ground-line of the carrying-wheels.

The discharge-chute from a stone-Crusher will discharge onto the lower end of the carrier mentioned.

The bucket chain or carrier 15 will be driven by a sprocket-chain (not shown) extending from the sprocket-pinion 30 on a shaft 31, 95 provided in the rear end of the frame, upwardly to a sprocket-wheel on the shaft 13. The shaft 31 will be driven by a belt 32, ex-

vzo

tending between the band-wheel 33 on the shaft 3l and the band-pulley 34 on the shaft of the stone-Crusher. The stone-Crusher may be driven by a belt applied to the band-pulley 35. For taking up slack in the bucket chain or carrier l5 the bearings 13, which carry the shaft 13 at the upper end of the elevator-frame, are mounted on slides 13b, which are attached to a cross-bar 13c and adjusted by means of the screw 13d and the handwheel nut 13e, engaging therewith and held in a yoke l3f, provided on the cross-bar 7 of the elevator-frame',

To i'old the/elevator, the operators reel up a suiiicient quantity of the chain 2O on the reelsliaft Q1 to move the elevator-section 7 from the inclined position in which it is used to a substantially vertical balancing position. It is swung by the balancing-point and lowered into a horizontal position by paying out the chain 2O from the reel-shaft.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a carrying-truck of a folding upper section of elevator-frame pivoted on ijXed journals supported above the truck and arranged to fold to a position over the truck, a lower sliding sectionot` elevatorframe mounted in an upright position in bearings on the carrying-truck to slide substantially vertically and connected with the folding section by means to extend it downwardly when the folding' section is erected in an upright position, and a belt-carrier mounted on the elevator-frame, substantially as set forth.

2. The combination with a suitable carrying-truck mounted on wheels and having upwardly-extending supporting-arms, of an elevator consisting of frame and belt-carrier, said frame being' pivoted to the upper part of said supporting-arms to fold into a horizontal position over the truck, or be'erected in upright working position at the rear of the truck, and when erected move the lower receiving end of the carrier below the plane of the tread of the truck-wheels, substantially as set forth.

3. The combination with a suitable supporting and carrying truck of a folding elevator, having an upper section or frame pivoted on journals on the carrying-truck and adapted to fold into a horizontal position over the truck, and a lower section mounted to slide substantially vertically in the truck-.frame and connected with the upper section, so as to operate simultaneously, and a carrier provided on said elevator, substantially as set forth.

4. The combination with a suitable supporting and carrying truck of a Jfolding elevator, having an upper frame section pivotally mounted on the truck adjacent to its lower end, and adapted to be erected in an upright working position or folded over the truck in transporting position, and a lower frame-section mounted in the truck-frame to slide substantially vertically and adapted to be projected downwardly in working position or withdrawn into transporting position, and a carrier mounted on the elevator-frame, substantially as set forth.

5. The combination with a suitable supportlng and carrying truck of a ioldmg elevator,

having an upper frame-section pivotally' mounted on the truck and adapted to be erected in an upright working position or laid over the truck in transporting position, a lower frame-section mounted in the truck-frame to slide substantially vertically and to be projected downwardly into working position or withdrawn into transporting' position and connected with and adapted to work simultaneously with the upper frame-section, a carrier mounted on the elevator frame-sections and means for manipulating the sections in erecting or folding the same, substantially as set forth.

In witness whereoi- I have atlixed my signature, in presence of two witnesses, this 24th day of July, 1903.
