LOADING APPARATUS.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed April 19, 1906. Serial No. 312,537.

To all whom it may concern.-

Be it known that I, NELS JoReENsEN, a subject of the King of Denmark, residing at Craig, in the county of Burt and State of Nebraska, have invented certain new and useful Improvements in Loading Apparatus, of which the following is a specification.

This invention relates to loading apparatus in general, and it has particular reference to an improved apparatus whereby heavy and bulky material, such as manure and compost, may be loaded into wagons, the special object of the invention being to provide an apparatus of this class of simple and improved construction, whereby an entire wagon load may be deposited upon a platform that constitutes a part ,of the loading apparatus, means being provided whereby said platform may be elevated and tilted so as to discharge its contents into the body or box of a wagon which is driven to receiving position beneath the platform.

Further objects of the invention are to simplify and improve the general construction and operation of this class of apparatus.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings there has been illustrated a simple and preferred form of the improved apparatus, it being, however, understood that no limitation is necessarily made to the precise structural details therein described, but that changes, alterations, and modifications within the scope of the invention may be resorted to when desired. 4

In the drawings, Figure 1 is a perspective view of the improved loading apparatus, showing the same in load-receiving position. Fig. 2 is a side elevation'showing the apparatus with the load-carrying platform elevated,

dotted lines being employed to indicate the platform in a tilted or load-discharging position and also to indicate the several parts of the apparatus in load-receiving position. Fig. 3 is a top plan view showing the appara tus in load-receiving position.

Corresponding parts in the several figures are designated by like characters of reference.

The improved apparatus includes a baseframe B, the side members of which consist of skids or runners'l 1, which are suitably connected and spaced apart at intervals by means of cross-pieces 2 2. Said side mem-' bers are also connected by means of obliquelydisposed brace-rods 3 3.

- Pivotally connected with the side members 1 I of the base-frame, as by means of a transverse bolt'or connecting member 4, are the side members 5 5 of a lifting-frame L, which said side members are securely connected by means of obliquely-disposed brace-rods 6 6. The bolt or connecting member 4 affords a fulcrum for a lever-frame consisting of converging side members 6 6. The apex of the lever-frame is connected with the side members 5 5 of the lifting-frame L by means of rods or connecting members 7 7, the leverframe being disposed approximately at right angles to the lifting-frame, so that when the latter lies flat upon the ground, as shown in Fig. 1 of the drawings, the lever-frame will occupy an approximately perpendicular position.

The load-receiving platform P is composed of suitable flooring 8, secured upon a pair of cleats or flange members 9 9, whereby the floorin is slightly elevated above the ground when t e platform occupies the loadreceiv ing position indicated in Fig. 1. At the inner edge of the platform is an upstanding flange form may be modified to the extent of providing such bracing and reinforcing means as may be deemed necessary to provide a construction of the requisite strength and durability.

The platform is connected with the liftingframe L, as by means of a bolt or connecting member 12, extending throu h the extremities of the side members 5 of t e lifting-frame and through the cleats or flanges 9 upon the under side of the platform, the arrangement being such that the pivotal member 12 shall be disposed nearer the inner than the outer edge of the platform. It follows that the outer portion of the platform will overb alance the inner portion of the same, this being obvi- -ment of the draft.

ously desirable to insure convenience in tilting the platform for the discharge of the load from said platform into the box or body of a wagon, as will be presently more fully described.

For the purpose of sustaining the floor of the platform in an approximately horizontal or level position while the load is being elevated the inner edge of the platform is connected by a link-bar with the base-frame, preferably through the medium of one of the cross-bars 2 of said base-frame, with which the said link-bar is hingedly connected, as by means of interengaging eyebolts 16. The upper or outer end of the link-bar is detachably connected with the platform by means of a flexible element, such as a wire rope or cable 17, which is guided over a pulley 18 near the upper or outer end of the link-bar, one end .of said flexible element being attached to the platform and the opposite end thereof being adapted to be detachably connected with the link-bar, as be means of a cleat 18.

Near the free end of the lever-frame there is supported a block or pulley 19, and a similar block or pulley 20 is connected with the cross-bar 2 near the end of the base-frame distant from the lever-frame. A flexible hoisting element 21 is connected with the hanger 22 of the pulley 19, said hoisting element being reeved beneath the pulley 20, over the pulley 19, and finally under a guidepulley 23, suitably supported upon the'baseframe, the terminal end of said flexible element being extended to the point of attach- As will be readily understood, power of any well-known description ing-frame L, which latter ascends as the leform a'load has been placed upon the platform, draft is applied to the hoisting element 21, thus exerting stress in a downward direction upon the elevated free end of the lever-frame, the stress being communicated through the connecting members 7 to the lift ver frame approaches a recumbent or ap proximately horizontal position. As the free end of the lifting-frame is being elevated it levates the loaded platform, the approximately horizontal position of which is maintained by means of the link-bar 15. When the proper elevation has been attained, an empty wagon is driven beneath the platform,

and the free end of the flexible element 17 is then cast loose, thus causing the platform to be automatically tilted by the preponderance of weight upon the outer portion of said platform, the load being discharged directly into the wagon beneath. As soon as the load has is restored to its normal approximately horizontal position by simply .pulling the flexible member 17, the latter being made fast, as be-' fore, for the purpose of securing the platform. The strain upon the draft element 21 is now released, and the platform will then gravitate to its initial load-receiving position.

i As will be seen from the foregoing description and from the accompanying drawings this improved loading apparatus is extremely simple in construction, and it may therefore be manufactured at a moderate expense. .Its construction is such that heavy loads may be elevated and discharged "into wagons with great facility and with comparatively slight expenditure of power.

Having thus described my invention, I

claim and desire to secure by Letters Patent of the United States- 1. In a loading apparatus a'base-frameya platform, a lifting-frame connected pivotally with the platform intermediate the edges of the latter and connected pivotally with the base-frame near one end of the latter, alinkbar connectedpivotally with the base-frame, and means for connecting said link-bar detachably with the platform near one edge of the latter.
