RAILROAD PAVING PLANT.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed August 5, 1905. Serial No. 272,846.

To all whom it may concern:

Be it known that I, GEORGE MERRIMAN, a citizen of the United States, residing at T- ledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Railroad Paving Plants, of which the following is a specification.

The object of my invention is the provision of an improved railroad paving plant which shall be adapted for easy transportation from place to place and parts of which can quickly be moved into operative position.

Heretofore the tank and mixer of analogous plants have been built between the ends of two cars and both had to be removed and placed upon another car for shipping, the dismantling and removing requiring much time and being very expensive.

My invention consists in locating the mixer, sand-tank, scales, sand-screen, engine, &c., upon a movable platform or carriage, making thelatter adjustable longitudinally upon the end of the car, and providing means for lowering the sand-tank when the plant is to be transported.

It further consists in certain novelties of construction and combinations and arrangements of parts hereinafter described and claimed.

The accompanying drawings illustrate an example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principle.

Figure 1 shows in side elevation the end of a car with a movable platform or carriage and several parts of the plant mounted there on. Fig. 2 is an end view of Fig. 1 in elevation. Fig. 3 shows the platform with the apparatus which it supports run out in position for use. Fig. 4 is a top plan view of one of the platform-screws. Fig. 5 is a top plan view of the movable carriage.

Referring to the several figures of the drawings, the numeral 1 designates the two I-beam side sills of the car-underframe; 2, the channel-beam end sill, of less depth than the side sills; 3, the crossframe I-beams, of less depth than the side sills, said beams being located above the body-bolster; 4, two channel crossbeams 5, the two I-beam side pieces of the movable platform; 6, the I-beam cross-frame tie-pieces; 7, the guide-lugs secured to the side pieces 5 and engaging the outer flanges of the side sills; 8, the threaded lower sand-box lugs, riveted to the side pieces of the platform; 9, the sand-box frame; 10, the threaded upper sand-box lugs, secured to the corners of the sand-box frame; 11, the sand-box screws, reversely threaded at the ends and provided with holes to receive an operating-bar 12, the two platform-screws, one at each side of the movable platform; 13, the flanged head of the screw; 14, a fixed bearing for the head, said bearing being secured to the channel-beams 4, as shown; 15, holes in the screw for an operating-bar; 16, screwlugs secured to the inner surfaces of the I- beam sides of the movable platform; 17, the removable part of the housing for the sandelevator chain; 18, the sandbox; 19, the sand weigh-box; 20, the scales; 21, the asphalt-bucket; 22, the sand and asphalt mixer; 23, a Westinghouse engine 24, the removable or adjustable part of the asphaltum-delivery pipe, and 25 is the end of the sand-drier.

Upon the remaining portion of the frame are located the asphaltum-tank, furnace, sanddrier, steam-boiler, &c., in any well-known way, said parts not being shown.

Fig. 3 shows the movable platform with the necessary apparatus thereupon run out in position for use, the said platform being high enough from the ground or track to allow the end of a cart to pass beneath the same for the reception of the load which is dumped from the mixer.

hen it is desired to transport the plant to another place, first, the removable part of the housing 17 and the removable part of the pipe 24 are detached and the weigh-box 19 and scales 20 moved from above the mixer; secondly, the sand-box screws 11 are revolved and the sand-box lowered to a position where the top of the sand-elevator housing is fourteen feet six inches from the rails, this height over all allowing the car to pass through bridges and tunnels, and, finally, the platform-screws 12 are revolved, sliding the movable platform backwardly upon the carunderframe to the position shown in Fig. 1 of the drawings.

From the foregoing description it becomes obvious that I have produced an improved paving plant which fulfills the conditions set forth as the purpose of the invention.

By my construction and arrangement the platform may be moved from the position it occupies upon the end of the car when adapted for transportation to a position for use and the removable parts adjusted in a few hours, whereas the two car plants require several days expenditure of time to adapt them for practical use or operation.

What I claim isl 1. The combination with a car-underframe, of a platform movable longitudinally thereof and beyond the end of the same; guiding means for the platform upon the underframe; and means for moving said platform comprising a plurality of screws revoluble in fixed bearings, and threaded lugs.

' 2. The combination with a car-underframe, of a movable platform; a sand-box; sand-box screws and threaded lugs; the sandbox being supported by screws which when turned raise or lower the sand-box, for the purpose set forth.

3. The combination with a car-under-- frame, of a movable platform; a sand-box supported by the platform ;'means for raising and lowering the sand-box; and means for reciprocating the movable platform upon the underframe.

4. The combination with a car-underframe, of a movable platform; means for reciprocating the same; a sand-box upon the platform; means for raising and lowering the sand-box; and a housing for an elevatorchain, part of said housing being removable.

5. The combination with a carunderframe, of a movable platform carrying an asphalt and sand mixer; means for recipro, eating the platform; and an asphalt-delivery pipe, a part of said pipe being removable.

6. The combination with a car-underframe, of a movable platform; a sand-box frame; sand-box screws; and threaded lugs secured to the sand-box frame and movable platform; the screws engaging the lugs and being reversely threaded.

7. The combination with a car-underframe, of a movable platform; means for guiding and restraining the platform in its movements relative to the underframe; a platformscrew having its head engaging a bearing which is secured to the underframe; and a threaded lug upon the platform.

8. The combination with a car-underframe, of a movable platform; means for reciprocating the same; a sand-box supported by the platform; and means for raising and lowering the sand-box.

9. The combination with a car-underframe comprised of side sills and cross-frame beams, of a platform made of longitudinal and cross-beam members and located upon and supported by the side sills, a movable iand-box sup orted by the platform, means or longitudinally of the underframe, and means .for moving the platform to and from a position where a part thereof projects beyond the end of the underframe.

In testimony whereof *I affix my signature in presence of two witnesses.
