To all whom it may concern:
`a spcilcation:
My improvement in` grain-doors consists of a vertical catch-bar at one end, mounted at its upper end on an eccentric stud ot' a handlever, and at its lower end having a slot ivorking on a stud-pin7 the lslot being so inclined that when the eccentric stud is worked to raise and draw back or lower and push forward the upper end of the catch-bar, the lower end will Work in the same manner, thus making a powerful catch-'bar to hold one end of the grain-door by being pressed into. a groove in the door-frame, the other end being putin a groove to beginwith, and the catch also binds the door fast and-prevents it from shaking, and at the saine time it locks the door against rising, by its beveled upper corner passing under a beveled top to the groove in which the catch engages.
Figure 1 is a side elevation of our improved door, and Fig. 2 is ahorizontal section taken onthe line m w of Fig. 1. f
Similar letters of reference indicate corresponding parts.
A is the door, which at one end fits in a groove, B, in the door-frame, and at the other end shuts against the grooved plate C, and has the catch-bar D fitted to its side on the eccentric stud F of a handhaver, E, at its upper end, and on the stud-pin G by its inclined 'slot H at the lower end, so that by Working asnew and desire to secure by Letters Pati ent- 1. The catch-bar D, connected to door A by eccentric lever E F, stud G, and inclined slot H, in combination with grooved plate G on` the door-frame, substantially as specified.
2. The catch-plate D, having the beveled upper corner I, in combination with beveled top J of the groove, and the eccentric lever and the stud I, and slot H, substantially as.
specified.
