FREDERICK FRANK KANNE, OF WATERVILLE, MINNESOTA.

ELEVATOR OR CONVEYER.

SPECIFICATION forming part of Letters Patent No. 599,101, dated February 15, 1898.

Application filed December 28,1896- Serial No. 617,234. (No model.)

To ctZZ whom it may concern.-

Be it known that I, FREDERICK FRANK KANNE, aresident of Waterville,in the county of Le Sueur and State of Minnesota, have invented certain new and useful Improvements in Elevators or Oonveyers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in elevators or conveyors; and it consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the, claims.

In the accompanying drawings, Figure 1 is a view illustrating an embodiment of my invention. Figs. 2 and 3 are detailed views. Fig. 4 represents another embodiment ofthe invention; and Fig. 5 is a view in section,

showing the relative positions of a flight and,

the casing.

In Fig. 1, A represents a casing, in the corners of which are journaled the sprocketwheels 1, 2, 3,and 4:, on which is mounted an endless sprocket-chain. At suitable distances apart the links are constructed with laterally-projecting ears on a, to which the flights O are riveted. Each flight consists of a vertical portion or band I), which is perforated for its attachment to the ears on the grain-carrying receptacle; It will thus be observed that the series of flights, in connection with the walls of the elevator-casing, serve to form a series of moving receptacles for elevating and conveying grain from one point to another.

The casing may be provided at the top of its upright portion with a gate (1 and also I may have a gate e in the horizontal portion of its upper end, so that the grain may be discharged at either point.

From the construction and arrangement of 5 5 proved elevator is placed in a vertical position the inclined flights will discharge as readily as an elevator disposed in a slanting position with flights set at right angles to the chain. My improved elevator will operate effectually in any position in which it may be set,.from a perpendicular to a horizontal position, while a flight set at right angles to the chain will not work in a perpendicular position of an undershot elevator. In overshot elevators my improved flight or cleat will have the same advantages in filling and carrying as where used as an undershot, and will also discharge at a high rate of speed, because it will then throw the grain more upward and outward at the point of returnand therefore will not carry back'the material to be conveyed.

With my improved flight the work of the elevator inany position in which it may be set is improved. The dip and filling are also improved, the carrying capacity of the elevator is enhanced, and the discharge isrendered perfect whether the elevator be set perpendicular, horizontal, or at an intermediate point.

The exact form of the flights or cleats is 'HOlLIllLtQIlPt-l so long as the working face is disposed at an inclination to the chain or other carrying device.

In Fig. 4 the application of my invention to an undershot elevator is shown.

My improvements are simple in construction and effectual in all respects in the performance of their functions.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with an elevator-casing and an endless chain arranged to be operated therein, of a series of flights attached to the chain each flight consisting of a Vertical portion which fits against the chain and with a forwardly and downwardly inclined portion, the forward and side edges of which fit against the front and side walls of the elevator-casin g, substantially as set forth.

2. The combination with an elevator-casing and an endless chain arranged to be operated therein, of a series of flights attached to the chain, each flight consisting, of a vertical portion which is attached to the chain, and with a forwardly and downwardly inclined portion the forward and side edges of which engage the front and side walls of the casing, the side edges of the flights being provided with strengthening-flanges, substan-
