FLIGHT FOR CONVEYERS.

SPECIFICATION forming part of Letters Patent N o. 702,906, dated J une 24, 1902.

Application tiled April 14, 1902.

T (LH whom, it 717,601/ concern:

Be it known that I, ALFRED M. AcKLrN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Flights for Conveyers; and Ido hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to conveyers, and has Io special reference to the conveyer shown in Letters Patent No. 605,621, granted to me June 14:, 1898, its object being to provide a sirnpler form of hinge between the flight-frame and the fiight than that illustrated in the patent, so as to sustain the upper end ,of the flight against the strain brought against the lower end thereof in its forward movement.

It consists, generally stated, in a conveyer having a reciprocating flight-frame provided with a downwardly-projecting strip to which to connect the hinge and downwardly-projecting legs back of said hinge-strip, leaving a space between the strip andthe legs, and a hinge of any suitable flexible material secured on the back of such strip and secured to the front of the fiight, the body of the fiight extending up beyond the base of the depending hinge-strip of the flight-frame, so that as the material operated upon presses against the base of the flight its upper end will be sustained from' forward movement by the rear face of the hinge-strip.

It also consists in certain other improvements,which will be hereinafter more particularly set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure l is a side view of a portion of thev Serial No. 102,787. (No modeld As the general parts of the apparatus are the same as described in the said patent, it is not necessary to describe them in detail.

The cylindrical bar a of the main frame has secured to it the flight-frames b by means of concave seats c on the flight-frames and U- shaped bolts d, passing around the cylindrical bar and engaging the iiight-frame- Depend ing from the forward end of such flight-frame is the metallic hinge-strip e, which is pref- 6o erably made the full length desired for the hinge, and back of the same are the depending legs f, which support the flight in its forward movement, bearing against the rear face by means of the foot'g. The fiight L is 65 formed of a-metal plate, which is supported by means of the leather or like'iiexible hinge t. As shown in the drawings, this flexible. hinge is connected to the rear face of the strip e by means of bolts lo, passing through the 7o hinge-strip e, the fiexible hinge t, and the rear confining-strap n, the leather hinge being confined between the rear face of the hinge-strip e and such confining-strap fn. The night is secured to the hinge t' inflike man- 75 ner, the flexible leather hinge extending down on the front face of the flight and bolts o passing through the iiight, through the dexible hinge t', and through the confining-strap p. It will be noticed thatthe body of the 8c flight extends up back of the base of the depending hinge-strip e, so that the upper end of the flight is sustained against forward movement by said depending strip through the leather hinge supporting the upper end of 85 the flight and said hinge-stripe. In this way as the Hight is reciprocated within the trough fr the pressure of the grain, sand, ashes, or other material operated upon is sustained by the depending legs of the flight-frame, while 9o the upper end of the flight is held from forward movement due to leverage-'pressure of said material to be moved against the base of the flight by the depending hinge-strip e, extending below and in front of the upper end of the night. In case anylarge body of material should gather in the trough, so that the leverage above the feet g of the legs f should be greater than the leverage below the same, which would have a tendency to push the np- 10o per end of the flight back and so bring unnecessary strain upon the leather hinge, l may employ the knees t upon the legs f some distance above the feet g thereof, which will serve to receive such backward strain brought upon the upper portion of the Hight and prevent any unnecessary tearing or like strain upon the leather or like exible hinge.

The operation of the device is apparent. As the flight moves forward the material pressing against the lower end thereof brings leverage upon the upper end of the flight, as above stated, and this upper end is sustained from forward movement by the downwardlyprojecting hinge-strip e without the necessity of any special piece other than the ight and the strip to sustain it in position. On the backward movement of the conveyer the ilexible hinge permits the flight to swing forward and pass over the material in the trough, so as to be ready to take a second hold upon the same upon the next forward reciprocating stroke of the conveyer. In case of the gathering of any large body at any point in the conveyer the knee t sustains the upper portion of the light against backward movement and so protects the flexible hinge from injury.

lVhat I claim, and desire to secure by Letters Patent, is-

l. Inaconveyer,thecombinationofaightframe having a depending hinge-strip and back of the same depending` supporting-legs, of a flight having its upper end-extending above the base of the hinge-strip, and a ilexible hinge connecting the llight to the hingestrip. v

2. In a conveyer, the combination with a {light-frame having a depending hinge-strip and back of the same depending supportinglegs, of a ilight having its upper end extending above the base of the hinge-strip and a flexible hinge secured to the back face of the hinge-strip and to the front face of the flight.

In testimony whereof I, the said ALFRED M. ACKLIN, have hereunto set my hand.

ALFRED M. ACKLIN.
