SPECIFICATION forming part of Letters Patent No. 674,480, dated May 21, 1901.

Application filed December 3. 1897- Serial No. 660,704. No model.)

To all whom it may concern:

Be it known that 1, DAVID J. SHELDRICK, a citizen of the United States, residing at O0- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Conveyors; and I do 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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of a section of chain and one of my improved attachments. Fig. 2 is a top plan view of the same. Fig. 3 is a cross-section. Fig. at shows one of the-parts of the attachment detached. Fig. 5 is a section of a conveyer having a flight secured to the chain by the attachment when use is made of one form of flight. Fig. 6 is a plan view of the same; Fig. 7, a view similar to Fig. 5, showing a flight of slightly-diflerent constructions. Fig. 8 is aconventional illustra: tion in plan of a conveyer embodying my improvements. Fig. 9 is a section on the line a: on of Fig. 8.

Heretofore numerous ways have been followed or proposed in the fastening of flights, scrapers, buckets, due, to conveyer-chains of the class known as cable-chains or coilchains-that is to say, chains made up of similar links each formed of a round rod with ends welded together; but I have found serious disadvantages to be incident to each of these that are known to me.

A indicates the chain as a whole in the accompanying drawings, it being made up of the links a and a, formed and joined in the way described, those at a being at right angles to those at a.

B indicates the body part of the attachment. It is made up of two counterparts b h, each having a bar longitudinal of a chainlink and means for attaching the bar to a flight. These are approximately as long as the open space within the vertical links a. They are formed with grooves or sockets'b extending from end to end, there being an edge flange at b b and a core or central flange at b. When the two parts I) b are brought together, they can inclose the two bars of one of the links Ct,'tl16 latter lying in the grooves 17 The edge flanges b and the cores 19 approach each other, but can be left spaced in such way that a powerful grip can be attained upon the bars of the link. Through the link-that is, between said bars-and through the cores b pass the bolts O O, by which the binding of the parts together is effected. Atone end of each half I) b a plate is cast integral therewith and lying in planes transverse to the body part. When the two parts of the attachment are firmly fastened in place upon the chain, these two plates d cl together constitute what is practically a single plate D.

E indicates the flight. The chain passes through the center of it, and the attachmentplateD is firmly rivet-ed to it. The aperture at the center of the flight to receive the chain may be large enough to allow the free passsage of both the horizontal links a and the vertical links a, as the plate D is of such dimensions as to close entirely such aperture, and in such case the chain is made up in shorter sections, which are subsequently Fastened together to make the complete conveyer; but where it is desired to frequently substitute new flighls they may be formed in two halves, as shown at E in Fig. 7, or a out, such as at e, can be formed in the flight E in Fig. 5, by which the parts of the flight can be bent sufficiently to permit it to be put in place at any time in proper relation to the attachment.

In case such a flight as that shown at E in Fig. 9 is employed the chain will be made in short sections, and after one of said sections has been passed through the central aperture 0, to bring the flight in the desired position the attachment B can be placed in position and secured to the chain and flight, after which the sections of chain can be connected together.

If the flight is provided with a slot, as at c, it will be seen that it can be easily slipped upon any link in the chain and quickly secured in position by the attachment B.

I am aware of the fact that it has been proposed to make a flight for cable-chains of two pieces of metal divided on vertical lines and one overlapping the other, each with a slot or.

too

cut-away portion in its inner edge, and am also aware that conveyers have been made of cable-chains in which the flight-carrying links have been made in two semi-oval halves, together with screw-threaded connecting devices which permit the attachment of a flight, by means of screw-threaded sleeves adapted to engage with the ends of the halves of the links which are secured to the flights. I believe myself to be the first to have provided a conveyer made up of a ,cable chainthat is, a chain having a series of links all substantially similar to each other, each lying in a plane at right angles to those adjacent together with flights, each of which is integral throughout and which extend to oints on each side of the chain that are equally distant, and attachments or connecting devices which join the chain to the flights, each attachment being adapted to close the passageway through the flight for the chain-lin k, said chain-link being integral from end to end.

What I claim is 1. In a conveyer, the combination with the chain formed of similar links a ct at right angles to each other, an attachment B secured to the link a and formed in halves or parts adapted to inclose the side bars of the link, the bolts passing through the link, the plates (1 d at the ends of the parts b b and integral therewith, and the flight E having a chain passed through its center and secured to said plates d d, substantially as set forth.

2. In a conveyer, the combination of a cable-chain formed of a series of similar solid links, the adjacent links extending at right angles to each other, and a flight secured to a link on the chain which extends continuously from end to end through the flight, said flight extending integrally from points beyond one side of the'chain to points beyond the opposite side of the chain, the integral ends of the flight being equidistant from the chain, substantially as set forth.

3. In a conveyor, the combination with a chain comprising links each of which is integral from end to end and inseparable from the adjacent links, of a series of flights secured to said chain, each flight lying in a transverse plane between the ends of one of said links, and attachments for the flights, each attachment being formed separately from its flight and from its chain-link and composed of two parts adapted to lie on opposite sides of the chain-link, each part of each attachment having a bar longitudinal of its link and having a plate integral with the bar, means for clamping the longitudinal bars of the attachment to its chain-link, and means for fastening the plates of each attachment to its flight substantially as set forth.

4. In a conveyer, a chain-link continuously each end to an adjacent link to which it is connected permanently or non-detachably, a flight lying in a transverse plane between the ends of said link, an attachment having a plate adapted to be riveted to the flight, and having two bars longitudinal of the link, and means for clamping the said bars to the link, substantially as set forth.

5. In a conveyor, the combination of a cable-chain, consisting of similar alternate solid links arranged to have each link at right angles to the adjacent ones, a flight having a passage through which a link of the chain can pass,whereby the flight will extend integrally from points beyond one side of the chain, the ends of the flight being equidistant from the chain to points beyond the opposite side of the chain, substantially as set forth.

6. In a conveyer, the combination of a cable-chain composed of similar solid links, adjacent links being arranged at right angles to each other, a flight adapted to have the chain extend centrally therethrough, and means for detachably connecting. the chain and flight together, the flight extending integrally from a point at one side of the chain to an equidistant point on the other side, substantially as set forth.

7. In a conveyer, the combination of 9. cable-chain, an attachment consisting of two similar halves each provided in its inner face with grooves adapted to receive the side bars of a chain-link, bolts adjustably connecting said halves, a flight having a slot or passage extending from about its center through one edge and adapted to receive the link aforesaid, and means connecting the flight to the said attachment, substantially as set forth.

Intestimony whereof I affix my signature in presence of two witnesses.
