UNITED STATES LEONARD E. HURST, 0F DETROIT, MICHIGAN.
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
truck1 is shown conventionally to have
wheels2 and
end bolsters3 provided with
guide blocks4. The conveyor chain is of well known construction consisting of mid dle links 5 carrying fiat headed
pins6. 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 links9 are formed with.
ears10 between which the
dogs12 are mounted on the
pins13. The
tails14 of these dogs are so heavy that the heads are held elevated so as to enga e the
bolsters3 of the trucks.
These chains slide on
channel bars15 and 16. The return runs of the chains may be carried by the
dogs12 which slide on the
web17 of the
lower channel16 as shown in Fig. 3. The pedestals which form the 1924. Serial No. 705,352.
subject matter of the present invention each comprise a
base20 which may be attached to the floor by a
bolt21, two
side members22 and the
web23 provided with the flanges or
ribs24, 25 and 26. The web also has a perforated lug 27 to receive the
bolt28 and a
flat face29 to receive the short angle iron bracket 30 having a
horizontal leg31.
The
bolt28, therefore, alone secures the pedestals to the channels and the
brackets29 to the pedestals. The
upper channel15 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 flange33 and an upright web or
leg34 is secured to the brackets 30 by means of
bolts35 and this flange 34: is of proper height to extend into the slots 36 of the
guide blocks4. The holes for these bolts are punched in the
base flange33 and determine the posit-ions of the
bolts21.
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.
