Wall 6 is a hinged door 7 JAMES F. PECK, OF SHERMAN. TEXAS.
HOPPER-DOOR.
To all wlw/n t may concern:
Be it known that I, JAMES F. Prien, al citizen of the United States, residing at #S10 N. lValnut street, Sherman, in the county of Grayson and State of Texas, have invented certain new and useful Improvements 1n Hopper-Doors. ofj which vthe following is a specification. i i
This invention relates to a hopper door especially designed for usev with a vertically movable weighing hopper adapted to receive and weigh cotton seed, the` seed being discharged from the hopper through said door into a receiver and from thence conveyed by a screw conveyer to any suitable chute or other storage place.
The invention resides especially in the manner of hinging and operating the door, and in the novel features of construction hereinafter described, pointed out in the claims, and shown inv the accompanying drawings,.in whichz Figure 1 is a bottom plan view of a hopper equipped with a door and door operating mechanism in accordance with the present invention, the door being shown in closed position.
Fig. Q is a vertical section through the lower portion of the hopper the door heilig in open position.
Fig, 3 is a vertical section, thedoor in closed position, and
Figs. -1 and 5 are detail perspective. views of certain levers of the door operating mechanism, shown detached.
Referring to a detail description of the drawings wherein likey reference characters designate corresponding parts throughout the several views, l designates.l the hopper provided at its lower end with an inwardly inclined wall 6, and arranged opposite said normally closingbeing the-hopper bottoni.
The invention relates particularly to the means for holding this door closed against the weight of seed pressing on it during the filling of the hopper and the means for opening the door when the desired weight of seed has been introduced.
Across the lower front of the hopper is a square shaft 8 mounted in bearings 9, the shaft having of course, cylindrical portions fitting the bearings. vExtending inwardly from the shaft toward the door are two levers 10 in the form of bars having square sleeves 11 at their oiiter `ends to fit the l Specification of Letters Patent.
Application filed March 12, 1917..

Serial No. 154,256.
shaft S, flanged' as "at 12 on one side and perforated as at 13.
(.)n the lower outer face of the door is mounted a second shaft llt and on said shaft are mounted levers 15 having at their inner ends cylindrical sleeves 16 to turn on the shaft 1l and having at their outer ends a i side flange 17 with perforation 18.
A third shaft 19 passes through the perfor-ations 13 and 18 and connects the levers together and to said shaft are connected the lower ends of coil springs 20, the upper ends of the springs being secured to the hopper.
When the door is closed the levers 15 overlap and rest on the levers 10 and the pressure of the seed on the door causes a thrust along the line of the levers and against the inner vertical sid'e of the square shaft 8 and the greater the pressure the more firmly locked said door becomes.
To one end of the shaft S is connected an operating lever 21 with a pull chain 22, within easy reach of the scale attendant.
It will be obvious from Figs. 2 and i of the drawing that when the shaft S is rocked b v level' 21 the lever 10 will swing downwardlyl into perpendicular position, thus drawing downwardly and outwardly the shaft 1.9 and throwing the lever 10 from a horizontal to an inclined position, causing the door 7 to open.
That I claim is :4-
2. IThe combination with a hopper having a door hinged at its upper end to a side wall of the hopper at apoint above the lower end thereof and adapted to extend in la downward inclinationA across the bottom of the- ,side portions of the door at the lower end thereof, each lever connection including a lever pivotally connected at one end with the door and a lever ixedly secured at one end to said shaft, a transverse shaft pivotally connecting the inner ends of the pairs of levers, and a coiled spring connected at one end to said last mentioned shaft and at its opposite end to the hopper above `the first mentioned shaft, each pair of levers being adapted to extend in longitudinal alinement when the door is in closed position.
3. rlhe Combination with a hopper having a door hinged atits upper end to a side wall of the hopper at a point above the lower end thereof and adapted t o extend infa downward inclination across the bottomof the hopper and to engage a. portion on the opposite side wall of the hopper when in closed position, of operating means for the door including a shaft extending across that side of the hopper' to which the door--is hinged, said shaft being supported for rotation on the hopper below the hinged connection of the door, a lever connection between oppovsite end portions of the shaft and opposite side portions of the door at the lower end thereof, each lever connection including a lever pivotally connected at one end with the door, and a lever fixedly secured at one ing in longitudinal alinement with eachv other when the door is in closed position.
lln testimony whereof I aiiix my signature.
