CHAIN AND TRUCK GUIDE.

Application filed; April 9,

T 0 all ivhom it may concern:

Be it known that I, LEONARD E. Hmzs'r, a citizen of the United States. and residing at Detroit, in the county of \Vayne and State of h lic-higan, have invented new and Improved Chain and Truck Guides, of which the following is a specification.

This invention relates to means for supporting conveyor chains for wheeled trucks and for guiding the trucks, and its particular object is to provide simple and effective means for supporting channel guides for conveyer chains and for supporting the guide bars for the trucks.

In many factories wheeled trucks are loa ded at different points and then pushed into line to be slowly moved through enameling ovens or dry kilns, or are moved along lines of workmen who carry out certain steps in the assembling or finishing of the articles or machines on the trucks, and it is often of advantage to have no tracks for such trucks, whi 11 makes means for guiding such. trucks through the ovens: or along the line of work men very desirable. The present simple combination, therefore, of a support and guide for the conveyer chain and of a guide for the trucks has been found to be. of great advantage.

In the accompanying drawing, Fig. 1 is a side elevation of a truck and a guide therefor and for the conveyer chain. 2 is a transverse section of the guides and supports. Fig. 3 is a. section on the line 3-3 of Fig. 2.

Similar referen echaracters refer to like parts throughout the several views.

The truck 1 is shown conventionally to have wheels 2 and end bolsters 3 provided with guide blocks 4. The conveyor chain is of well known construction consisting of mid dle links 5 carrying fiat headed pins 6. and the side links 7 having slots 8 through which the heads of the pins may he slipped when the links 7 are at right angles to the middle links. At any desired intervals the middle links 9 are formed with. ears 10 between which the dogs 12 are mounted on the pins 13. The tails 14 of these dogs are so heavy that the heads are held elevated so as to enga e the bolsters 3 of the trucks.

These chains slide on channel bars 15 and 16. The return runs of the chains may be carried by the dogs 12 which slide on the web 17 of the lower channel 16 as shown in Fig. 3. The pedestals which form the 1924. Serial No. 705,352.

subject matter of the present invention each comprise a base 20 which may be attached to the floor by a bolt 21, two side members 22 and the web 23 provided with the flanges or ribs 24, 25 and 26. The web also has a perforated lug 27 to receive the bolt 28 and a flat face 29 to receive the short angle iron bracket 30 having a horizontal leg 31.

The bolt 28, therefore, alone secures the pedestals to the channels and the brackets 29 to the pedestals. The upper channel 15 is securely held between the pedestals by the flanges or ribs 24: and 26. As these pedestals are castings which require no machining, the chain guide can be produced at minimum cost. The channels are rolled sufficiently accurate at the mills. An angle iron guide bar comprising a base flange 33 and an upright web or leg 34 is secured to the brackets 30 by means of bolts 35 and this flange 34: is of proper height to extend into the slots 36 of the guide blocks 4. The holes for these bolts are punched in the base flange 33 and determine the posit-ions of the bolts 21.

The whole structure is very rigid. It can be quickly taken up and put down in a new location when a move is found necessary, and the top edge of the upright flange 34: is a. good guide for material trucks which are to be moved by this chain as above described.

I claim 1. In combination, two channel bars constituting guides and supports for conveyer chains, pairs of pedestals supporting the bars, each consisting of a web having longitudinal flanges to position the bars, and a bolt extending between the pedestals of each pair to cause them to grip the channels.

2. In combination, two superimposed and spaced bars constituting guides and supports for conveyer chains, pairs of pedestals supporting the bars, each consisting of a base and a web having longitudinal flanges to position the bars, a bolt extending across between said bars from one pedestal to the other of each pair to cause them to grip the bars, brackets secured to the pedestals along one side of said guide barsfor the chains, and a third guide bar embodying a vertical web secured to said brackets.

3. In combination, two superimposed and spaced channel bars constituting guides and supports for conveyer chains, pairs of pedestals supporting the channel bars, each pedestal comprising a vertical web and longitudinal flanges to position the channel bars, a bolt extending across between the channel bars and from one pedestal to the other of each pair to cause them to grip the bars, angle brackets secured by said bolts to the pedestals along one side of said guide bars, and a third guide bar of angle iron secured .to said brackets with one flange extending upwardly to serve as a guide for Wheeled vehicles.

4. In combination, two superimposed and spaced channel bars constituting guides and supports for conveyer chains, pairs of pedestals supporting the channel bars, each pedestal comprising a vertical web and longitudinal flanges to position the channel bars, a bolt extending across between the channel bars and from one pedestal to the other of each pair to cause them to' grip the bars, angle brackets secured by said bolts to the pedestals along one side of said guide bars, a third guide bar of angle iron secured to said brackets with one flange extending upwardly to serve as a guide for wheeled vehicles, and a chain slidable in said channel bars and embodying pivoted dogs adapted to engage and move the wheeled vehicles guided bv said angle bar.
