.the like.

The primary object of this invention is to pick up objects at one location and toy transport them to a remote location for the discharge of the same. Another important object of this invention is to utilize the towing force of a tractor or the like in raising the object to the position in which it is transported. V

A meritorious feature of this invention resides in the provision of a pair of beveled platforms that are pivoted to each other and the novel stop means provided for limiting their relative pivotal movement in the closed position. Another important feature resides in the combined means for limiting relative pivotal movement of the platforms and for retaining objects upon the platforms.

A final important feature of the present in vention to be specifically enumerated herein resides in the ring, cable, and hook arrangement which necessitates a minimum of effort on the part of the operator in arranging the device for either loading or unloading.

These, together with various ancillary features and objects of the invention which will later become apparent as the following description proceeds, are attained by the present invention, a preferred embodiment of which has been illustrated by way of example only in the accompany ing drawings, wherein:

Figure 1 is a top plan view of the loading device showing the same in the open position and with the alternative closed position indicated in dotted outline;

Figure 2 is a reduced top plan view of the loading device in the position preparatory to closing and raising an object;

Figure 3 is a top plan view of the loading device illustrating the same in the closed position and indicating in dotted outline an object supported thereon;

Figure 4 is a transverse vertical sectional view taken upon the plane of the section line 4-'-4 of Figure 1; and,

Figure 5 is a side elevational view of the loading device with an object thereon in position to be transported, with parts broken away and shown in section.

Reference is now made more specifically to the accompanying drawings, wherein like numerals designate similar parts throughout the various views, and in which the loading device is indicated generally by the numeral Ill.

The device In comprises a pair of platforms l2 and I4 which are pivotally connected at the rear ends by a bar [6 for relative opening and closing movement. The adjacent side edges of the platforms are beveled as at l8 and the bar I6 is pivoted to the platforms [2 and I4 adjacent the beveled edges l8 by means of the pivot bolts 20, pivotal movement of the bar [6 relative to the platform l2 being limited by a stop pin 22 which is received in a notch 24 formed in the end of bar I6.

The bar l6, together with the upstanding side rail 26 on the outer side edges of the platforms [2 and I4 and the blocks 28 at the forwardend of the platforms, constitute retaining walls upon are beveled rearwardly and outwardly adjacent the beveled edges l8, as at 34.

Eye loop 36 and 38 are pivotally secured to the forward ends of the platform 12 and I4 by suitable pivots 40, and a ring 42 is secured to the eye 36 by a short length of cable 44. A relatively longer length of cable 46 is secured to the ring 42 and carries a hook 48 at its outer end.

The use of the device Ill will be readily understood. Theloading device is towed to the loading position by passing the cable 46 through an eye 50 carried on a cross bar 52 of a tractor or suitable towing vehicle, -not shown, and the hook 48 is engaged in the ring 42. The device is towed in this manner to the loading position with the device l0 sliding over the ground surface and with the platform I 4 trailing as shown in Figure 1. The device I0 is towed to a position relative to the object-54 so.as to be adjacent the beveled edges t8. The hook 48 is then removed from the ring 42 and engaged with the eye 38. As will be readily apparent, further towing action by the tractor will cause the platforms to pivot towards each other and the object 54 will be raised upon the inclined planes formed by the beveled edges 18. The closing movement of the platforms will be limited by the pin 22 and the blocks 28, and the object which now rests on the 3 platforms I 2 and I4 will be prevented from falling (:1; thereof by the rails 26, blocks 28, and the After the object 54 has been loaded, the towing action may be continued, in which case the platforms l2 and I4 serve as a sled, until the unloading position is reached, at which point the hook 48 is removed from the eye 38 and engaged with the ring 42; Further towing action'willzthen open the platforms causing the object "54 to fall "or slide therefrom, and the device is in condition for a repeat operation. A

The present invention, with the exception "of the fasteners, may be formed entirely of wood, however, a construction of wood reinforced by iron has been found quite satisfactory, 'and in fact a heavy sheet of metal secured to the.under-- surface of the platforms is highly desirable when the device is to be pulled over abrasive materials.

From the foregoing, the construction and operation of the device will be readily understood and further explanation. is believed to beunnecessary. However, since numerous modifications and changes will readily occur; to thoseskilled in the art after a consideration :of the foregoing specification and accompanying drawings, it is not desired to limit the invention to the exact construction shown and described, but all suitable modifications and equivalents may :be resorted .to falling within the scope of the appended elaims.

Having described the invention, what claimed as new is:

1. A loading device comprising a pair of elongated platforms arranged in side-by-side relation and having their adjacent side edges beveled, means hingedly connecting, the rear ends of said platforms for opening and closing movement 'ofsaid platforms relative to :each other, a tow cable, and means carried at the forward end of. each platform for selectivelyattaching sa-id tow cable of the platforms.

6. Thecombination of claim 5, wherein the bar is pivoted to the platforms adjacent the adjacent side edges of the latter, and the rear platforms of the adjacent side edges of the platforms being rearwardly divergent. V

7. A loading and transporting device comprising a pair of elongated platforms arranged in .side-by-side relation, a transverse bar overlying the platforms adjacent their rear ends, said bar being-pivotally connected to each of said platforms and at one end projecting beyond such pivotal connections, an upstanding stop on one of theplatforms to the rear of the bar and engaging such projecting portion of the bar to limit pivotal movement of the latter, a pair of abutting transverse blocks, each of said blocks being secured to the top of one of theplatforms adjacent the forward end of the latter for limiting the closing movement of the platforms, the adjacent side edges of the platforms being beveled, a flexible towing element, and means for selectively connecting the towing element to the forward .end of one or .bothof the platforms.

8. A loading and transporting device comprisbeing vpivotally connected to each of said platto one or both the forward? endso'f the platforms.

ward portions of the adjacent sides of said platforms are forwardly and outwardly beveled.

5. A leading and transporting device comprising a pair of elongated platforms arranged in side-bysside relation, a transverse bar overlying :the platforms adjacent their rear ends, said bar forms, an elongated flexible towing element having a securing ring intermediate its ends, .sa'id element having one end attached to the forward end of one of the platforms, a further ring fixed to the forward end of the other platformna hook on. the free end of the towing .element selectively engageable with either of they rings.
