HOISTING-WAGON.

SPECIFICATION forming part of Letters Patent No. 753,888, dated March 8, 1904.

Application led July 11, 1903. Serial No. 165,121.` (No model.)

To a/ZZ whom it may concern,.-

Be it known that I, ALBERT E. JOHNSON, a citizen ofthe United States, residing at Northfield, in the-county of Rice and State of Minnesota, have invented new and useful Improvements in Hoisting-Wagons, of which the fol-4 hoisting position.

- novel construction,combination, and arrange-v ment of Aparts hereinafter more fully described A stillfurther object is to employ simple mechanism for operating an apron mounted uponthe hoisting apparatus. Y

With the -above and other objects in view the invention consists in providing a wagonframe which is pivoted to standards which are mounted upon the rear axle of the vehicle. Mechanism is provided whereby the standards can be swung inward by the forward movement of the vehicle, so as to cause the body thereof to assume an inclined position. Means are also provided whereby when the vehicle is drawn forward the apron upon the wagonbody will be moved upward, so as to hoist any material which may be arranged-thereon.

The invention also consists in providing mechanism for automatically returning the apron to normal or loweredv position after the discharge of material therefrom.

The invention also consists .in the further and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a side elevation of my improved hoisting mechanism. 'j Fig. 2 vis a longitudinal section therethrough. Fig. 3 vis a side elevation thereof, showing the body of the vehicle in an inclined position. Fig. 4 is a rear elevation of the standards and the parts connected thereto, the body of the vehicle being reforward portion of the apparatus. Fig. 6 is a perspectiveview of the clutch-operating.

bar, and Fig. 7 is a detail view of the bodysupporting standard of the device.

Referring to the figures by numerals of reference, 1` is the front axle of the vehicle, having traction-wheels 2 of any suitable construetion arranged thereon, and to this axle is secured a tongue 3, through which the. draftanimals are adaptedto be hitched in any suitable manner. The upper surface ofthe rear portion of this tongue is provided withya recessl, over which extends an apertured plate 5, and seated. within this recess and below the plate 5 is a ball 6, formed at the end of a stem 7 which is integralwith a block 8. Rods' 9 extend from the corners of the block and are bolted or otherwise secured in the forward portion of the frame 10vof the vehicle-body. This framev is formed of side beams 11, and pivoted to these beams at points between'their ends are standards 12, which are connectedv has traction-wheels 15 loosely mounted there-l on, and revolublewith each wheel isa clutch member 16. A drum 17 is loosely mounted on the axle adjacent each clutch member 16, and these drums have tapered ends 18, which project into the clutch members 16. Gears 19 are formed at the inner ends of the drums '17 and mesh with smaller gears 20,.which are secured .to shafts 21, vjournaled within the standards 12, and secured to the inner ends of -the shafts are disks 22. A,rod 23 is eccentrically connected to each disk and has a piston24 at itsy other end which is slidably mounted within a cylinder 25', secured to the inner face of lthe' adjacent'standard 12. This cylinder is closed at the ends for the purpose hereinafter more fully described. To one'of the cross-strips 13 is pivoted a lever`26, to one end'of which are pivoted oppositely-extend-v IOO lIo

in the upper ends of the standards 12. Pulleys 31 are journaled in brackets 32 on the outer faces of the standards 12, near the pivots thereof, and are substantially in alinement with the drums 17 hereinbefore referred to.

A shaft 33 is journaled in brackets 34, secured to the lower surfaces of the side beams 11, and this shaft extends transversely of the body of the vehicle and is provided near each end with drums 34, to which are secured the ends of cables 35, which are fastened at their other ends to brackets 36, fastened to the lower ends of the standards 12. A drum 37 is arranged at one end of the shaft 33 and outside the body of the vehicle, and secured to this drum is a cable 38, which extends over one of the pulleys 31 to the drum'17 in alinement therewith. A ratchet 39 is formed'with drum 37 and a spring-pawl 40 serves to prevent the drum from unwinding the cable. This pawl is preferably formed of a centrally-pivoted lever, the forward end of which is normally depressed by a coiled spring 41. A-lever 42 is arranged adjacent the pawl and has a cam formed at one end and adapted to contact with and force the pawl into engagement with the ratchet 39 when so desired.

A shaft 43 extends transversely of the body of the vehicle in a plane above shaft 33, and upon this shaft are secured, preferably, two drums 44, to which are secured the ends of cables 45, the opposite ends of which are fastened to a compressing strip 46, slidably mounted upon rods 47, which are secured to the inner faces of the side beams 11 and extend longitudinally thereof. Uoiled springs y48 are mounted on the rods 47 and are interposed between the compressing-strip 46 and blocks 49, arranged at the forward ends of the rods. Sprockets 50 are also secured to the shaft 43, and mounted thereon are chains 51, which are connected. by transversely-extending slats 52, forminga conveyer-apron. These chains 51 are also mounted on sprockets 53, j ournaled on a shaft 54, extending transversely of the body of the vehicle, near the rear end thereof. A board 55 is arranged adjacent the front end slat of the conveyer-apron and in a plane preferably at rightangles to the apron.

To one end of the shaft 43 is secured a drum 56, upon which is mounted a cable 57, which extends over the other pulley 31 and to the remaining drum 17. This drum has a ratchet revoluble therewith and normally engaged by a spring-pawl 59, similar to the one heretofore described, and provided with an operatinglever 60, similar to the lever 42. Levers 61 are fulcrumed at their lower ends to the forward ends of the side beams 11 of the vehiclebody, and the upper ends of these levers are connected by a rod 62, which extends in front of the seat 63 at the forward end of the vehicle. Each lever 61 is connected, by means of a cable 64, with one of the arms 28, said cable 65 being arranged within the guide-recess 30 of one of the standards 12 and fastened in one of the apertures 29.

In using the apparatus herein described the hay or other material to be stacked is placed upon the apron, which is normally in the position shown in Figs. 1 and 2. The machine is then drawn forward, and when desired the operator' presses forward upon one end of rod 62, so as to swing the lever 61 adjacent thereto and impart longitudinal movement to the cable 64, which is connected to it and which is arranged at the left side of the apparatus. This cable will serve to swing the arms 28 and the lever 26, so as to press the end of one of the rods 27 into contact with the gear 19, adjacent thereto, thereby forcing the tapered end 18 of the drum 17 into frictional contact with the clutch member 16. Cable 38 will thus be wound upon said drum, and the cables 35 will be simultaneously wound upon the drums 34. The standards 12 will therefore be swung into position shown in Fig. 3 and the body ofthe vehicle raised to an inclined position. By pressing the lever 42 forward the cam end of said lever contacts with the spring-pawl 40 and forces it downward into engagement with the ratchet 39 of drum 37, and the parts are therefore prevented from returning to normal or lowered position until after the pawl has been released from the ratchet, when said parts will return by gravity. After the body of the vehicle has been raised at a desired incline the lever 61, which has been pressed forward, will be allowed to return to normal position, and the traction-wheels are therefore free to rotate without changing the positions of the parts. After reaching the place at which the material is to be stacked the vehicle is turned around, so as to bring the rear end thereof over theV stacking-point, and during such movement the other lever 61 is pressed forward, so as to throw the clutch of the other drum 17 into operation, thereby winding the cable 57 and causing drums 44 to rotate and Wind the cable 45. As these cables are connected to the compressing-strip 46,said strip will be drawn downward and compress the springs 48. Simultaneous with this movementl the chains 51 will be moved upon the sprockets 5() and 53 and the conveyer-apron will be carried upward, thereby discharging material over the end of the vehicle-body. The spring-pawl 59 of ratchet 58 will prevent the compressed springs 48 from expanding until after all the material upon the apron has been removed. When it is desired to return the apron to its normal position, the lever 60 is drawn inward, so as to release the spring-pawl 59 from ratchet 58 and the springs 48 therefore expand and press the strip 46 upward on rods 47 and cause the cables 45 to unwind fromdrums 44. Cable 57 will therefore be wound simultaneously upon drum 56 and unwound from the drum 17, to which it is secured. It will of course be understood that as soon as the` apron IOO IIO

lvhasbeen raised a desired distance the lever 61 will be released, so as tov permit the independent movement of the parts in relation to the traction-wheels connected to their drum 17. .By providing cylinders 25 and the reciproeating pistons 24 the rotation ofthe various drums of the device is retarded, and injury to the parts `as a result of sudden return to normal position `is thus prevented... Inthe foregoing descriptiomI have shown the preferredform of my invention; but Ido not limit myself thereto,l as I am aware that modications may be made therein withoutdeparting from-the; spiritfor sacrificing the adi 5 vantages thereof, and I therefore reserve the right to make such changes and alterations as may fairly fall within the scope of my invention. v Having thus fully describedthe invention, 2o what I claim as new,and desire. to. secureA by *Letters Patent, isl l.
