Application-'April 1, 1937, Serial No. 134,879 ' 2 Claims.r (Cl. 296-61) This :invention relates to a detachable, pivoted endgate-type collapsible stock loading and un loading chute, and the purpose of the invention is to generally improve upon similar prior pat Figure 6 is a detail View of the pawl and ratchet mechanism. arrangement possessed of appreciable structural Figure 8 is; a detail view‘of one of the custom ary retention hooks for a cross-bar such as is Figure 7 is a View of a fragmentary sectional nature showing the structure collapsed and fold iïented and marketed structures by providing an ‘ ed up into‘end gate'forming position. distinctions and refinements in keeping with good policy in so far as a structure of this type is concerned. In reducing the invention to actual practice, I have found it expedient and practicable to used to hold >the endgate in closed position, Referring now to the drawings by distinguish ing reference characters and to properly illus 10, tratethe novelty, I have shown in the drawings utilize an elongated tail gate of a length sulfi a fragmentary portion of what may Vbe called cient to permit it to be swung down to an inclined - a truck, wagon, or similar vehicle. This is de noted by the numeral '9. ~ It comprises a bottom lll and slide walls l | and an under-frame l2. On position whereby to‘ provide a gang-plank, said 151 .'gatebeingprovided with open slatted confining sides pivotally mounted thereon', whereby to pro vide a simple and satisfactory chute' structure. One- feature of the invention is to provide pivotally mounted confining sides on the gang 20 plank', these being automatically moved to so called erect position through the instrumentality the under-frame, as shown to advantage in Fig ure 3, I provide. suitable bearing brackets I3 for a rotary shaft vI4 provided withcable winding drums >l5 at ,opposite ends.

An 30 „and lowering the chute. Affurther» feature of. construction has to do with adjustable rod jointing means between the confining side walls and the elongated endgate forming the so-called gang-plank. Other features and advantages will become more readily apparent from the following de scription and drawings. In the drawings, wherein like numerals are employed to designate like parts throughout the outstanding part thereof is the longitudinally elongated board or plank 22 forming the >so called endgate. This is heldin an up and out-of the-way position by a removable locking bar 23 supported in suitable suspension hooks or clips 25 on the side walls of the truck. The gang-plank 22 is provided on its inner or upper side with suitable cleats 25 to facilitate ascension and descension of stock` and cattle. This gang-plank is detachably mounted on the 40 views: bed or bottom of the wagon, as shown more satis Figure 1 is a top plan view showing a rfrag mentary portion of a truck body and illustrating the improved loading chute as constructed in ac cordance with the principles of the present in 45 vention and showing it in its useful position. factorily in Figure 3. Here it will be observed that the gang-plank ís provided with eye screws or bolts cooperating with similar fixedly mounted eyes on the adjacent end of the wagon bottom lll. ‘ Figure 2 is a longitudinal section taken ap proximately on the plane of the line 2-2 of These features form accommodation means for 45 a removable pintle or rod 26. The rod slips through the eyes', referred to by the numeral 2l, Figure l. and the pintle is held in place by a linchpin or Figures 3 and 4 are transverse vertical sections on the lines 3-3 and 4_4, respectively, of Fig cotter key 28. Along opposite longitudinal sides the gang-plank 22 is provided with distinguish- ~ ure 2. able pairs of miniature posts 29 and 3U which Figure 5 is a view in cross-section calculated to show how the pivoted or swingable sides may be swung down, against the tension of the springs, 55 into folded compact relation. terminate in eyes, which eyes serve to slidably accommodate the assembling and adjusting rods 3|. In connection with the rods 3|, it will be observed that these serve primarily as hinges for 2 2,107,371 connecting the slatted side walls 34 to the gang plank. In accomplishing this, brackets are se cured to the lowermost slats and the brackets have eyes 33 projecting beyond said slats, as shown to advantage in Figure 2. The rods 3l are therefore rigidly mounted in these eyes 33 It is thought that the description taken in con nection with the drawings will enable a clear understanding of the invention to be had. There fore, a more lengthy description is thought unnecessary. While the preferred embodiment of the inven and are rotatably and slidably mounted in the adjacent eyes on the aforesaid posts 29 and 30. Spring means to be hereinafter described serves tion has been shown and described, it is to be understood that minor changes coming Within the field of. invention claimed may be resorted to to maintain the eyes 33 in abutting relationship with the eyes on said posts 29 and 30. Hence, since the side walls 34 are of a length greater than the gang-plank, to allow the inner ends to if desired. I claim: project into the wagon when the structure is as set up in Figure 2, it is` necessary that said side walls should be both slidably and hingedly con nected with the gang-plank, for when the side walls are folded into overlapping relation, the gang-plank is swung up to the position seen in Figure 7, the inner ends of said side walls 34 then become substantially flush or even with the hinge means 2S, preventing the side walls from interfering with the closing of the gang-plank when it serves in effect as an endgate. Attention is now called to the numerals 35 in Figure 5. These designate coil springs anchored on extensions 36 at one end, the extensions being on the bottom of the gang-plank. The opposite ends vare anchored as at 31 on the hing-ed lower 30 end portions of the swingable side walls. The springs serve to automatically swing the sides from the collapsed or folded position shown in Figure 5 to the erect loading position shown in Figure e. In this connection it will be observed that the numerals 38 designate stop fixtures l 10 1.

In a structure of the class described, a gang which limit the outward swinging movement of plank, said gang-plank being provided along op 35 posite longitudinal edges with upstanding fixed the sides. posts terminating in eyes, a pair of confining Then, too, the numeral 39 designates side walls of. a length greater than the gang a hinge leaf carrying a hasp or the like 40 which may be carried by the overlapping swingable ` plank, said side walls being provided adjacent the gang-plank with brackets, and a pair of 40 40 sides and anchored down in place in any suit duplicate rods mounted in said brackets, said able manner (not shown) to hold the sides in collapsed folded position against the tension of rods being disposed in parallelism with respect the springs as illustrated in Figure 5. to the gang-plank and hingedly and slidably Hence, by releasing the hasp 40 from its fastening mounted in the eyes on said posts and fastened means, the sides swing out to chute-forming re in said brackets, whereby to permit the sides to have the desired hinging and sliding action and springs carried by the gang-plank and fastened to parts of the side walls to control the sliding movement of the side walls and also to hold the side walls in upright position.

It is to be noted that the free ends of the aforementioned cables 29 are fixedly secured as at 4l to the gang-plank so as to bodily hoist or lower the chute in a requisite and convenient manner.
