TRUCK.
SPECIFICATION forming part of Letters Patent NO. 572,104, dated. December 1, 1896. Application filed March 21,1896. Serial No. 584,311. (Nqmodeh) To all whon't it may conccrlu.
Be it known that I, VICTOR CHABTENER, a citizen of the United States, residing in Pittsburg, county of Allegheny, State of Pennsylvania, have invented certain new and useful Improvements in Trucks, of which the fol lowing is a specification.
My invention relates to trucks; andit consists of mechanism for elevating and lowering trucks and their frames respectively.
My invention is illustrated in the accompanying drawings, wherein-- Figure 1 is a side elevation of my improved truck with a photographic-printing frame, the truck being shown in two positions on the tracks. Fig. 2 is a top view thereof. Fig. 3 is an end View, and Fig. 4 is a side elevation and part section of the truck and of the frame. Fig. 5 is a bottom view of the truck and frame. Fig. 6 is an end elevation showin g the structure and the sun-printin g apparatus mounted thereon. Fig. 7 is a side elevation of the truck-wheel and 0f the eccentric. Fig. 8 is a section on line 8 8 indicated in Fig. 7. Fig. 9 is a section on line 9 9 in Fig. 8, showing the roller-bearing between the truck-wheel and the eccentric.
Similar letters of reference indicate corresponding parts in all the views.
For conveying of heavy or easily-breakable loads or of such that cannot be handled trucks must be provided whose platforms can be lifted and lowered, and difierent hoisting apparatuses were devised for the purpose.
The devices used heretofore for the handling of heavy or breakable loads require, however, complicated apparatus for the lifting of the platform, and their operation is dependent on special hoisting apparatus. The mechanism I have devised for this purpose is contained in the truck itself and so constructed that even a heavy load will be safely and easily handled.
The truck consists of four wheels 10, mounted in pairs on eccentrics g, rigidly keyed to axles h, pillowed in brackets f, combined in pairs and supporting the platform cl, screwed to plates e, and of the lifting-gear, comprising worm-wheels m, keyed to the axles h, worms 71, set on shaft 0, pillowed in hangers p, screwed to the platform of the truck.
In the drawings, my improved truck is illustrated as designed'for-use in an apparatus for making photographic prints from large negatives, such as prints of large working drawings requiring a very large glass plate and correspondingly large frame. In this case the wooden table d, forming the platform of the truck, is fitted into the frame a, holding the glass plate 1).
Platform or table d is screwed to the four plates e, combiningbrackets f, bearing the boxes for axles h in pairs to a set, holding the wheels to and eccentrics gin their relative position. Eccentrics g are rigidly keyed to the axles h. They are grooved on their circumference, and the surface of the groove is smoothly finished and hardened. The truck-wheels 10 form thus practically only a rim around the eccentrics, gliding with their smoothly-finished inner surfaces on antifriction-rollers k, traveling in groove 7' between flanges i. Axles h are thus set eccentrically in relation to the truck-wheels, and as the platform of the truck rests on the axles the vertical position of the platform will be changed by changing the position of the eccentrics within the truck-wheels. This is done by one gear,constructed in the following manner: On axles h are set worm-wheels m, rigidly keyed thereto,and are driven by worms at, set in corresponding position on the shaft 0, pillowed in hangers p, screwed to'the platform. The .wormgears are right and left handed, respectively, in order to make the motion of the eccentrics within the truck wheels go on in opposite directions, whereby their action on the truck-wheels w is counteracted. The end of the shaft 0 is squared and handle q fitted to it. Worm-shaft o is operated by the handle q,eccentrics 9 being turned 7 thereby to equal angles, (though in opposite directions,) and by thus changing their relative position to the truck-wheels w lift the platform or table of the truck.
This construction of the truck is the principal part of my invention and may be applied to any purpose where it is required to change the vertical position of the platform of the truck. In cases where it is necessary to lift only one end of the platform, as may be by wagons conveying the charge to a fur nace, &c., this could be done by leaving out the worm-gear on one axle or by making worm n adjustably revoluble on the shaft 0.
In the sun-printing apparatus illustrated on the drawings my improved truck runs on track Z, made of an gle-iron, and passes through the wall or window of the building, and the rails are bent upward at each end to prevent sliding off of the truck. The track is supported on the outside of the building by suitable bracing t and within the building by standards 7' and 8. Standards .9 support only the tracks, secured to their tops. Standards r, which are correspondingly higher, support the tracks on shoulders u and the frame a, holding the glass plate I) on shoulders 41. The relative height of these shoulders to and r is calculated to give the plate d suitable clearance underneath the frame a when in its lowest position on the track, and the frame a is correspondingly high, holding the glass plate in such position that platform cl will be gently pressed against the glass plate 12 when lifted on the truck.
I claim as my invention and desire to Secure by Letters Patent 1. In a sun-printing apparatus, the. combination with a frame, adapted to hold a glass plate, and supported on standards, and with of wheels mounted in pairs of two on eccentrics, of worm-wheels, rigidly secured to the axles, a transversely-mounted shaft, worms, gearing with the Worm-wheels,rigidly secured to the shaft and means for rotating the transverse shaft whereby the platform of the truck is lifted or lowered.
In witness that I claim the improvements described in the foregoing specification I have signed my name in the presence of two subscribing witnesses.
