CORN-"ELEVATOB- Specification of Letters Patent.

Application filed December 17, 1904. Serial No.` 237,818.

To /LZZ whom it may concern.-

Beit known that 1, AUGUST OTTO, Jr., a citizen ofthe United States, and a resident of Sandwich, county of DeKalb, and State of Illinois, have invented certain new and useful Improvements in Corn-Elevators, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to a wagon-dumping device adapted particularly 'for use in connection with elevators for receiving grain directly from the wagon-box and conveying it to a crib or other receptacle.'

The invention contemplates means for tilting a wagon so that it will discharge its contents from the rear end of its box; and it consists in means for raising the front end of the wagon, and more specifically in means for controlling the elevating mechanism.

The inventlon consists in the construction and arrangement of parts to be hereinafter described, and illustrated in the accompanying drawings, inwhich Figure 1 is a detail end elevation. Fig. 2 is a sectional view7 on the line 2 2 of Fig. 1. Fig. 3 is a central vertical section. Fig. 4 is a vertical cross-section on the line 4 4 of Figs. 1 and 3. Fig, 5 is a detail plan view of the device. Fig. 6 is a detail section on the line 6 6 of Fig. 3, and Fig. 7 is a section on the line 7 7 of Fig.

For receiving the Wagon to be unloaded a platform 101 is provided, comprising side rails 102 and 103 and the cross members 104 105, covered by planking 106, the whole being mounted on truck-wheels 107 and 108.

Within an opening in the covering of this v platform rests a movable frame 109, deslgned to receive the front wheels of the wagon.

For supporting and raising this movable platform a framework is provided, including uprights 110 and 111 and diagonals 112, 113,

114, and 115, rising from the platform 101 and joined above by a rectangular inclosure 116, in which are journaled sheaves 117 ,and 118. Over these sheaves ass chains 119 and 120, which are looped own at one side to receive sheaves 121 and 122,` attached to the movable platform 109, the ends ofthe chains reaching upwardly therefrom and being secured to the'framework, as indicated at 123 and 124. The free ends of the chains 119 and 12() pass downwardly from` the pulleys 117 and 118 onto drums 125 and 126, mount-- 'shipper-rod 160.

ed on a shaft 127, journaled in the side memiV bers of the platform 101.

Guide-brackets 128 and`129 are mounted on the movable platform 109 to bear against the diagonal braces 113 and 115, respectively, as this platform is raised.. Preferably the pitch of these diagonals corresponds roughly to the chord of an arc throu h which the front wheels of a farm-wagon o usual length will turn when the wagon isv being tilted about the rear axle as a center. In the drawings the diagonale are shown as angle-.bars with the guide-brackets embracing on of the flanges.

Power is supplied from any convenient source, such as the common farm tractionengine, and is referably applied to the shaft 55. -Aworm-s aft152,suitablymounted ona frame 166, secured to the base of the platfornrn 101 and ,coperating with a worm- Wheel 75 156,I attached tothe shaft 127, is employed for transmitting power to the shaft 127. `TWO bevel-gears 1 54 and 155, turning loosely on the Worm-shaft, are driven in op posite directions from a gear 153 on the end of the shaft 55. The rotationof either of the gears 154 or 155 may be imparted to the worm-shaft by means of a clutch 157, splined upon it and actuated by a yoke 158, having a swiveled connection with the clutch. This yoke is operated by means of a hand-lever 163, pivotedl to the upright 110 at 164 and to the yoke at 165 and extending forwardly therefrom, so as to be easily reached by anv attendant standing near the foot of the conveyer. f

Means are provided for automatically disengaging the clutch `157 when the' movable platform 109 has reached the end of a prede- .termined range of movement. For this ur--l 95 posef a shipper-rod 160, the base of w `ch rests in an aperture in one of the side members 102 of the platform 101 the upper end being supported and guided by a racket 169, secured to the frame 116, is operatively connected to the yoke 158 by means. of a lever 159, fulcrumed at 170. Stops 161 and 162, reaching into the path of the movable platform 109, are adjustably secured to the IOO e operation of the deviceis as follows: The front wheels of the`wagon havin been placed upon the platform 106, the han -lever 163 is operated to throwtheclu'teh 157 into engagement with one of the pinions to rotate no tile drum and leise the pefoi'm. When the rod end being operatively eiigeg'ed with the letter ensei "ifs the stop ll, it moves the red 15G sui ,ently to the oiutch, sind thus sto the drum. Then it is desired to removethe Wagon from the platform, the attendent again actu-,etes the clutch by ineens of the hand-loiret 1&3 in order to rotete the dium in the opposite direction, and es the pietforin reaches the limit o1' its doWn- Wei-d movement it encounters the sto 162, and 'thus eutometioel'y disengeges the C utch.
