ful Dirt-Loading Machine, of which the fol-- lowing-is a specification.

This invention relates to improvements in machines for loading wagons and the like with dirt or other material'placed in the machine, one of the objects of the invention being toprovide novelmeans whereby the dirt or other material is elevated from an eXcavation into a receptacle for delivering the material into wagons, cars 'or the "like, the present invention being an improvement on that shown and described in the patent is ysued to me on July 6, 1915, No. 1,145,379.

A yfurther object of the invention is the provisionof improved means for elevating the platform of the machine from an excaf vation into position for delivering` the material intovthe hopper.

A further object provision of means of the invention is the for facilitating the turning of the machine when moving it.

'- parts With `the kforegoing and'other objects in which will appear as the description proceeds, the invention consists in the novel features of constructionV and combination of which will be more fully described hereinafter and particularlyvpointed out in y the claims. f

In the drawings accompanying and forming part of this specification,

v Referring to the drawings, 2 designates a 1 frame or truck carrying an axle 3, which is wheels 1, andon which frame standards; 5 having suitable standards being connected at supported by are, mounted braces 6, the

their upper ends by a cross beam 7 on the end portions offwhich are secured the front ends of downwardly and rearwardly inclinedside beams 8. The side beams are supported at their rear ends by a cross beam 9, to which are attached Va pair of standards 10, thestandardsbeing connected together ymeans of a king the different figures j y Specification of Letters Patent. i k] g,\,1391113e(1 June 7, 1921, application sied May 9, 1919. serial No. 295,930. f

co beams 8 are further connected tothe standj ards 10 by means of a pair of brace members or stays 12. I o

For facilitating the turning of the machine, I have provided a rear truck, formed of a cross beam 13 carrying an axle 111 and a pair of wheels or rollers 15. This truck is pivotally connected to the rear frame by bolt 1G passing ,through the lower cross beam 11 and the'truclr beam 13. From this construction it will be seen that the truck may be turned in any direc-l tion whereby it is considerably easier to guide the machine in anyl desired than if mounted on a rigid truck. Suitable means may be secured to the cross beam 13 for hauling the machine. This means may consist of a flexible member 17 of loop form,

as shown, for manuallyhauling the ma chine, lor a suitable draft tongue may be se-` direction cured to thebeam for permitting horses toY be hitched thereto.

A hopper 18 is fiXedly `mounted between the front end portions of the side beams 8 and has its bottom inclined downwardly and rearwardly. The i ported by means of bers 19 securedV nected together at a pair ofinclined memtheir upper and llower ends by a pair ofcross beams 20. The hop-y per is open at the top and frontv thereof, and end `is providedy with in- ,Y

adjacent its rear clined guide cleats 21 secured to the side walls and which are adaptedto receive and guide a gate 22 that can be adjusted verti;

cally by means of a cord 23 attached to the j hopper is further -suptothe beams 8 and con- C upper edge of the gate and passing over a j pulley V24 mounted on a cross bar 25secured at the upper ends of the guide cleats 21. By

the provision of this gate anV opening of any desired height may bey formed between the lower edge of the gate and the kbottom of the vhopper, whereby the amount of material supplied to the delivery end of the hopper| can be controlled; VSecured to the rear end of the hopper, approximately at the middle of its heightq is a cross beam 26, to which-is which gate opens outwardly. For operating hingedly secured an end-,gate27 adapted tok y i to close ythe lower end of the hopper, and

the gate27,f1 have provided a lever mechanisin, which comprises a cross bar 28 secured.

' ed at itsinner end ajpair of links 30 secured a pair of strips 34 are at their opposite ends to the lower portion of the gate 27. The lever 29 may be provided at its outer end with a'flexible operatring cord 31, whereby on pulling said cord downwardly the lever will operate to open the gate, as shown in Fig. 3, and when it is desired to hold lthe gate closed the cord 31 may be secured around the cross beam 9, thereby holding the outer end of the lever elevated, the rigid members 30 thus bearing against the lower edge of the gate and holding the same closed.

For facilitating vthe delivery of material from the hopper, I have provided an endless apron adapted to `travel on rollers 32 mounted in bearings at the upper and lower ends of the bottom of the hopper, and which apron'is formed of a plurality of slats 33 flexibly connected together, whereby the apron is adapted to travel around the bottom of the hopper, as clearly shown in Fig. 3. By the provision of'this apron the dirt or other material in the hopper will be caused to quickly gravitate to the lower end of the hopper, as the weight of such material will cause the apron to travel on the rollers 32.

For the purpose of holding the front frame 2 fixed relatively to the side beams 8, secured at one end to the standards 5 and at their opposite ends to the sides of the hopper. A pair of side arms 35 are pivotally mounted at one end thereof on the ends ofthe axle 3, and are secured together near theirl opposite ends by a cross strip 36. The arms 35 carry at their free ends a pairof bearings 3'? in,

which is mounted a rockable'shaft 38, to one side of which is secured a yrearwardly extending member 39 havin ysecured at Vits rear end a cross strip 40. ecured beneath themember 39 Vat the pivotal end thereof, is a spacing member 41,V which is suitably Y braced by a `stay 42 secured at one end to Vthe spacing member 41 and at its opposite end to the member 39. To the lower end of the spacing member 41 is rigidly secured a loading platform 43, which is provided with a back wall 44 adapted to receive the dirt when the platform is swung upwardly as hereinafter described. Carried by the truck 2 approximately centrally of its width, is a lengthwise extending vmember 45, provided near its front end with an aperture in which are pivoted the lower ends of a pair of upright rocking members 46, these members carrying between them at their upper ends a suitable pulley 47. A

pair of stays 48 are `pivotally secured at their lower ends one at each side Vof the truck 2 and brought together at their upper ends and pivotally connected with support* members, the strips having a pair of rollersV 50 secured between their ends back of the upright rocking members 46.. The upper ends of the stays 48 are connected by a pair of brace members 51, preferably of Ysheet metal, the opposite ends of whichare secured to the'rocking shaft 38, whereby the shaft will be permitted to rock slightly in its bearings. A rearwardly extending beam 52 secured to the truck 2 and4 provided with a pair of upstanding perforated ears or lugs 53 provides a support for a rpulley 54, through which passes a rope or cable 55, said cable passing over the pulley 47 and back over the rollers 50 and secured atl its end to the truck 2in any suitable manner. By means of this cable the platform may be raised'or lowered and may beheld in elevated position by securing the end of the cable to one of the upright members 10.V A pair of projecting members 56 are secured tothe uprights or standards 5 .and are adapted to contact with the cross Vstrip 40 carried by the member 39, when the platform is elevated to its highest position,

ywhereby the shaft 38 is rocked in its bear-V ings and the platform tipped backward, as shown in Fig. 3, thereby todeliver its load of material to the'hopper.

F roml the foregoing it will be seen thatV by reason of the fact that the platform is spaced away from its supporting beams it can be lowered below the surface to receive dirt from an excavation, and that when it is pulled up to its discharging position byv means of the cable 55 it will discharge its load of material into the hopper,

the weight of the material will cause the apron to travel around on the rollers and therein without departing from the spirit and scope of the invention as set forth in the appended claims.

Having thus described my invention, what I claim is: f i -1. In a device of the classi described, a

first frame; a hopper mounted on the frame;

a belt conveyer forming a bottom for the hopper; a second frame pivoted to the first whereupon f second frame; a supporting strip pivotally frame for vertical swinging movement; a platform on the second frame and discharging on the conveyer in the general direction of travel of the conveyer when the second frame is swung upwardly and rearwardly; means for swinging the second frame upwardly and rearwardly; and means for stopping the upward and rearward movement of the second frame whereby the material on the platform will be discharged on the conveyer and facilitate the movement of the conveyer.

2. In a device of the class described, a first frame; a second frame pivoted to the first frame for vertical swinging movement; a rocking memberpivoted at its lower end to the first frame; means cooperating with the upper end of the rocking member vfor swinging the rocking member rearwardly; a forwardly inclined stay pivoted at its lower end to the first frame; a rearwardly inclined connection between the upperend of the stay and the forward portion of the mounted on the stay adjacent to the upper end thereof and extended rearwardly therefrom; a roller on the rear end of the supporting strip and slidably engaged with the rocking member; a platform carried by the second frame; and means on the first frame for receiving material from the platform ment; a shaft mounted to rock in the second frame; a platform andy means for mountingthe platformv on the shaft; a rocking memberpivoted at its lower end to the first frame; means cooperating with the upper end of the rocking member for swinging the rocking member rearwardly; a forwardly inclined stay pivoted at its lower end to the first frame; a flexible element extended between the shaft and the stay; a supporting strip pivotally mounted on the stay adjacent to the upper end thereof extended rearwardly therefrom, the rear end of the supporting strip being engaged slidably with the rocking member; and means on the first frame for receiving material and from the platform when the second frame is swung upwardly and rearwardly.

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