ELEVATOR-GAS E.

SPECIFICATION forming part of Letters Patent No. 414,721, dated November 12, 1889.

Application filed August 27, 1888. Serial No. 283,9 t'7. (No model.)

To ctZZ whom, it may concern-.-

Be it known that I, AURELIUS V. Prrrs, a citizen of the United States of America, residing at Marseilles, in the countyof La Salle and State of Illinois, have invented certain new and useful Improvements in Elevator-Gases, of which the following is a specification, reference being had therein to the accompanying drawings and the letters and figures of reference thereon, forming a part of this specification, in which- Figures 1 and 3 are side views of the jointed portion of the elevator-case, showing it both in its folded and extended positions; and Fig. 2 is a perspective view of the jointed portion of the elevator-case to more clearly show its construction.

This elevator-case is more particularly designed for use on a grain-separator, where it is necessary to reduce the height of the elevator to permit the separator to pass under obstructions-such as low doors, gates, trees, 85c.

Referring to the drawings, A B represent the elevator-case. In order to form its joint so it can be let down at the top or folded, as shown in Fig. 1, a trianuglar-shaped cut is made in one side to remove a portion of the form shown at r, the lower part of which is hinged to the lower part B of the elevatorcase by means of hinges W, and forms adoor to close said opening when the part A of the elevator-case is upright and in line with the lower part B, as shown in Fig. 3. A button N or any other suitable fastening may be used to hold said door in the position shown in said figure, which button, for convenience, is omitted in Fig. 1. Said triangular-shaped cut or opening has its apex extended beyond the center line of the case, or about threefourths the way across, and the two parts A B of the case are severed or separated fromeach other from the apex of said tringular cut or opening to and on a line at right angles with the opposite side of the case.

The two parts A B of the case are connected at each side atthe apex of said opening by means of hinges S, in such manner that a joint is forrhed in the case, so that its upper part A may be let down or folded to be at right angles with the lower part B, as shown in Fig. 1.

hen the part A of the case stands in a vertical position, as shown in Fig. 3, the door r is turned up and secured closed to supply the portion cut out of the side of the case, and make it the same as if no such opening had been out in its side, and at such time the two parts of the case are held rigidly in the position shown in Fig. 3 by means of the bolt or screw 0, connecting the integral proj ecting lugs c on said hinges.

In Fig. 1 the case is represented as folded down, so that its two parts are at right angles with each other. When so folded, a triangular-shaped opening is made between the two parts A B, on their opposite side from the opening having door 7'. This opposite opening is provided with the door Ct, formed to fit it, which door is hinged to part B by means of the hinges 2, as shown and in a similar manner to that in which door r is hinged to said part. In this case, as the invention relates entirely to the construction of the elevator-case, no elevator chains or buckets are shown. The hinges S are located at the place shown, so that when folded the parts within the case may not be injured.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. The elevator-case shown and described, consisting of the two parts A and B, hinged together at the apex of a triangular opening between said parts, in combination with the hinges S, having the opposite side lugs 0, bolt 0, and the triangular-shaped doors r and a, substantially as and for the purpose set forth.

2. The combination of the elevator-case A B, hinges S, and doors a. and 'r, substantially as and for the purpose set forth.
