CONVEYER-OHAIN.

Application filed June 16, 1909. Serial No. 802,518.

To all whom it may concern:

Be it known that I, THOMAS A. CoLEM'AN, a citizen of the United States, residing at Longville, Louisiana, have invented a certain new and useful Improvement in Conveyer-Ohains, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to new and useful improvements in chain conveyer-s particularly adapted-for use in carrying ofl refuse lumber from sawmills, etc., and being designed as-an improvement on the chain conveyer illustrated in United States Letters Patent 'No. 627,482, granted to me June 27, 1899.

The essential features of my present invention reside in a novel construction of the flight which is constructed so as to be positioned on the chain conveyer in such a manner as not to impair the strength thereof, and the main body portion of which flight is adapted to swing vertically relative to the horizontal plane through which the chain passes.

In the drawings :Figure 1 is a planview of a trough in which a chain conveyer of my improved construction 0 erates. Fig. 2 is a plan view of one of the ights, and showing a portion of the chain to which said flight is fixed. Fig. 3 is a rear elevation of one of the flights. Fig. 4 is a cross section taken on the line 4 of Fig. 3. Fig. 5 is horizontal section taken on the line 55, Fig. 3. Fig. 6 is a horizontal section taken through the center of a modified form of the flight.

Referring by numerals to the accompanying drawings, 1 designates a trough, in one end of which is arranged a sheave 2", and passing through the trough and around said sheave, is an ordinary chain 3.

My improved flights which are fixed on the chain 3 at suitable distances apart are each formed in three pieces, A B and O, the parts A and B bein rigidly fixed to one am other and to one of the vertically disposed links of the chain and the main body portion C being hinged to the part B. The parts A and B comprise a pair of vertically disposed plates 1, fitted together and provided on their meeting faces with lugs 2, which enter corresponding recesses 3 thus preventing the plates from moving relative to each other when in position on the chain. The upper and lower corners of the plates 1 are cut away at the inner faces thereof as designated by 4 thus formin grooves at the upper and lower ends of-sai plates, which grooves receive the arallel body portions of one of the vertica 1y disposed links of the chain 3. The plates 1 are rigidly fixed to one another and to the link of the chain by means of a rivet 5 or like fastening device which passes through coinciding apertures formed in the centers of said plates. Formed integral with and projecting laterally from one of the plates 1 1s a pair of vertically disposed ears 6, and hinge upon pins or rivets 7 passing through said ears are ears 8 formed inte a1 with one end of the bin ed member 0 of t he flight. This member is composed of a vertically disposed front wall 9 from the rear side of which projects top and bottom flanges 10 and the ront face of the plate 9 is preferably concave in cross section as designated by 11.

, By concaving the front face of the flight it is prevented from climbing or riding over the refuse in its' passage through the trough.

A flight of my improved construction 1s very simple, strong and durable, and is adapted to swingvertically a short distance relative to the horizontal plane throu h which the chain and flight travels. main body of the flight maintains a hOIlzontal position on the bottom of the trough regardlessof the lateral rocking movement of the vertical link of the chaln to which said flight is fixed.

In. F1 6 I have shown a modified form of the flight wherein the main body portion 0 is formed integral with one of the plates 1, thus providing a rigid two part constructio In some instances, I may find it desirable to hinge one of the body portions C of the fli ht to both the plates 1 thus providing a double flight.

I am aware that minor changes on the construction and arrangement of the several parts of my device can be made and substi- Patented Apr. 4, 1911.

tuted for those herein shown and described without departing from the spirit of my invention.

I claim: 7

1. The combination with a conveyer-chain of a pair of plates having interfitting connection with each other whereby said plates may be secured in position within the link of a chain, means for holding said plates in their assembled position and a flight body hinged at one end to one of said plates in such a manner as to permit the free end of said flight body to swing above and below the plane traversed by the chain.

2. A flight for conveyer chains comprising a pair/of interfitting plates adapted to be positioned in one of the links of a conveyer chain, means passing through said plates and the link for rigidly uniting said plates, and a flight body hinged at one end to one of said plates in such a manner as to permit the free end of said flight body to swing above and below the plane traversed by the conveyer chain.

3. Aflight for conveyor-chains, comprising apair of interfitting parts having their adjacent corners cut away at top and bottom to form grooves to receive the links of a chain, and a flight body hinged at one end to one of said parts in such a manner so as topermit the free end of said flight body to swing above and below the plane traversed by the chain.

4. A flight for conveyer-chains, comprising two interfitting parts the adjacent corners of which are cut away at top and bot tom to form grooves adapted to receive the link of a chain, means whereby the artsare rigidly united and a flightbody hlnged at one end to one of said parts in such a manner so as to permit the free end of said flight body to swing above and below the plane traversed by the chain.

5: The combination with a conveyor chain, of a pair of plates fixed on one of the chain links, and a laterally projecting flight body hinged to one of said plates with the axis of the hinge between said flight body and plate horizontally disposed and extending lengthwise of said plate.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses, this 9th day of June, 1909.
