To all w/bmn it may concern:

Be it known that I, FRIEDRICH H. Wir- PLER, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Sewer-Pipe Trucks, of which the following is a specication containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to a sewer-pipe truck 3 and the object of my invention is to construct a simple and easily-operated truck for conveying large sewer-pipe and the like from one point to another.

In the manufacture of sewer-pipe the sec tions fresh from the press or former are comparatively soft, and therefore must be han.- dled carefully to prevent their becoming bent or out of shape before becoming thoroughly dried, and I propose to construct a truck particularly adapted for receiving and conveying larger sizes of sewer pipe or tile to and from the drying-room, and which truck is so constructed as to do away with the necessity of manually engaging newly-formed pipe or tile.

My invention consists, briey, of a pair of traction-wheels, a vertically-moving frame adapted to engage and lift the platform on which the pipe or tile is positioned, a pair of push-handles for actuating the verticallymoving frame, a casterwheel for supporting the rear of the truck while the same is being pushed forward, and suitable devices for engaging the sides of the pipe when in position in the truck, which last-mentioned devices are removed when the truck is used for handling newly-formed pipe.

My invention further consists in certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure I is a side elevation of my improved truck. Fig. II is a plan view of the truck.

Fig. III is a vertical section, enlarged, taken on the line A B of Fig. II. Fig. IV is an end elevation of the parts seen in Fig. III. Fig. V is a plan view of one of the pipe-engaging clamps carried by the vertically-moving frame. Fig. VI is a plan view of a stop against which the rear side of the pipe engages when positioned in the truck. Fig. VII is a front elevation of the stop seen in front of a vertical line through the center of said standard is a trunnion 2, on which is journaled a traction-wheel 3.

Arranged for vertical movement in each hollow standard l is a rack-bar 4 and projecting through a vertically-arranged slot 5 in the inner wall of each standard and carried by said rack-bar 4 is a pair of lugs 6, to which is secured in any suitable manner a vertically-arranged bar 7 that extends below the lower end of the adjacent hollow standard 1. Fixed to the lower end of each bar 7 is a longitudinally-extending angle-bar 8, the front and rear ends of which are supported by braces 9, that extend upwardly and are rigidly secured to the corresponding bar 7. Fixed to the inner face of each bar 7 and projecting inwardly therefrom is a pair of angle-brackets 10, and removably positioned in each pair of brackets is a vertically-ar ranged shaft 11, on the lower portion of which is mounted a block 12, carrying on its forward face a curved tile-engaging clamp 13, of rubber or analogous material. A coilspring 14 is mounted upon each shaft 11, above the block 12 thereon, and the lower end of said coil-sprin@r is seated in the upper one of the brackets 10. The normal tendency of these coil-springs 14 is to swing the blocks 12 upon the shafts 11 forwardly into the positions seen in Fig. II.

Pivotally mounted in bearings 15, which extend rearwardly from each hollow standard 1, is a segment 16, the teeth of which mesh with the corresponding rack-bar 4, and fixed to and extending rearwardly from each segment 16 is a handle 17.

Fixed in the upper ends of the hollow standards 1 are the outer ends of a pair of transversely-arranged rods 1S, the inner portions of which overlap one another and are adjustably held together bythe clampingcollars 19. Fixed to the inner face of each hollow standard 1, at the lower end thereof, is the 'forward end of a rearwardly-extending bar 20, and which bar is bent laterally, as indicated by 21, so as to extend across the IOO truck at the rear side thereof and overlap the corresponding end of the opposite bar 20. These overlapping ends 21 are adjustably held together by the clamps 22. Adjustably held at the centers of the portions 21 of tile bars 20 is a bracket 23, in the rear lower portion of which is arranged for operation a caster-wheel 24. Fixed on top of the .bracket 23 is a pair of upwardly-projecting ears 25, between which is pivotally held the lower end of an upwardly-projecting lever 26, the upper end of which is curved forwardly, as indicated by 27, and there being a notch 28 formed in the rear side of said lever. A leafspring 29 is secured at its lower end to the bracket 23, and the upper end of said spring bears on the front face of the lever 26 and tends to push the same rearwardly. Ad.-

justably held to one of the brackets 25 is a slotted bar 29, the forward end of which. carries a transversely-arranged curved centering-stop 30, the front face of which is faced with rubber or analogous material, as indicated by 31. Fixed to the handles 17 are the outer ends of a pair of transversely-arranged bars 32, the inner ends of which overlap one another and are adjustably held together by the clamping-blocks 33. When the handles 17 are in normal positions, the centers of these bars 32 occupy the notch 28, formed in the rear side of the lever 26. Handle-braces 34 are pivotally connected to the handles 17 and extend from thence forwardly and upwardly, and their forward ends are provided with hooks 35, which engage over the rods 18 adjacent the upper ends of the hollow standards 1.

The operation of my improved truck when carrying newly-formed pipe or tile is as follows: When the truck is being utilized for handling the newly-formed pipe or tile, the clamps 13, carried by the blocks 12, are removed from the bars 7 in order that the upper portion of the soft pipe will not be scratched or indented by coming in contact with said clamps. The truck is pushed, by means ofthe handle 17, into a position adj acent the platform on which a freshly-formed sewer-pipe is standing, and after the upper end of the lever 26 is pushed forwardly a short distance to allow the cross-bars 32 to. be disengaged from the notch 28 the rear ends of the handles are elevated to the positions seen by dotted lines in Fig. I, and consequently the segments 16 are rotated, and the rack-bars carrying the side bars 7 and the angle-bars 8 are moved downwardly, as shown by dotted lines in Fig. I. The horizontal portions of the angle-bars 8 are now in a position very close to the door, and when so positioned the truck is moved forwardly in such a manner that the horizontal portions of the angle-bars pass beneath the edges of the platform on which the sewer-pipe is located. The edges of the platform are elel end of said rearwardly-projecting frame, a`

vated slightly from the floor, owing to the arrangement of battens on their under sides. When the rear side of the pipe is engaged against the face of the centering-stop 30, the operator bears downwardly upon the rear portions of the handles 17, and so moves the same until the cross-bars 32 travel around the curved upper end 27 of the lever 26 and rengage in the notch 28. This action partially rotates the segments 16 and correspondingly lifts the rack-bars 4 and the side frames carried thereby. Thus the anglebars 8, carrying the platform and the sewerpipe, are elevated, and the truck is pushed to the proper point, where the pipe on its platform is unloaded by reversing the movements ljust described.

The width of the truck is varied by adjusting the various transverselydisposed rods 18 and bars 21 and 32.

When the truck is being used for handling pipe or tile after it has become dried or burned, the clamps 13 are repositioned upon the bars 7, and when a pipe or tile is arranged in the truck these clamps engage on the sides of pipe or tile and yieldingly hold the same in proper position while being moved by the truck.

My improved truck is very easily operated while being raised and lowered and very readily handles sewer pipe and tile of all sizes and is particularly applicable for moving newly-formed pipe and tile from the point where they are made to the dryingroom.

I claim- 1. In a sewer-pipe truck, a frame, traction-wheels supporting said frame, rack-bars arranged to move vertically in the sides of the frame, angle-bars carried by the lower ends of the rack-bars, segments arranged in the frames and meshing with the rack-bars, operating-handles for the segments, overlapping cross-bars connecting said handles, a frame extending rearwardly from the lower end of the irst-mentioned frame, a casterwheel arranged at the rear end of said rearwardly-projecting frame, and a spring-actuated handle extending upwardly from said frame for engaging the overlapping crossliars of the handles; substantially as speci- 2.
