This invention relates to a drain pipe conveyer. It 1 is aimed to provide ay novel construction whereby pipes orsections of pipes, for instance drain pipes, may be expeditiously handled as in laying `a pipeline, either within a ditch or on th surface of the ground or terrain. `One object of the invention is to provide a movable frame adjustable so as .to accommodate useI with pipes of various'v sizes and on which frame a conveyer or carriageis movable and has windlass-controlled cable means to 'suspend the pipe.

It is alsoaimed to provide a frame which may be effectively anchored in a ditch and which whenon the surface ofthe ground may move on wheels and which wheels at the front maybe turned or steered. i,

The more specific objects and advantages will become apparent from `a consideration of the description following taken in connection with the accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a view in side elevation showing the conveyer as used on the surface of the ground;

Figure 2 is an end elevation of the conveyer;

Figure 3 is a vertical section taken on the line 3-3 of Figure 1; I i y Figure 4 is a vertical section taken on the line 4-4 of Figure 2; p l y Figure 5 is a detailed section taken on the line 5-f5 of Figure 2;

Figure 6 is a view similar to Figure 1 but showing the device as used in a ditch and Figure 7 is a fragmentary end elevation of the device as used in Figure 6.

Referring specifically to the drawings a frame work generally designated I0 is employed. At the top, the frame work has a generally rectangular body consisting of `a pair of spaced parallel side rods I I rigidly but adjustably, if desired, connected at opposite ends by transverse bars I2.

Said transverse bars I2 vat each end have a pair of spaced depending ears I3 between which the upper sections I4 of curved llegs are interiitted and adjustably fastened by means of detachable bolts I6. Legs I5 also have lower sections I'I, preferably arcuate, which are slidable into and out of the sections I4, since the latter are hollow at their lower ends, in order to adjust the legs I5 to any desired permissible length. The sections I4 and I'I are adapted to be secured together at different adjustments by means of a binding screw as at I8.

The legs I5 may be swung on the bolts I6 as pivots to any desired distance apart at` their lower ends, and are fastened in such positions by passing bolts or the like I9` through selected openings'20 of links'2l, pivotedat 22 to the upper leg section I4.

At the lower end of each leg section. Il a bracket or fork 23 is provided, those at the rear preferably being rigidly connected to the adjacent leg section I'I while those at lthefront are preferably connected by swivel joints 24 to the lower` ends of the adjacent leg section I6 in order, Between the.

to enable turning on` vertical axes. spaced sides ,25 off-the brackets or forks, wheels 26 are journaled on axles 21 located between the sides and `detachablysecured in place by means of bolts 28 passed through openings 29 in such sides. The wheels maybe of any desired'size or constructionlbut preferably are equipped with pneumatic tires.' i, Y

The structure equipped with the wheels is pref;

` adapted to be lifted from place to place and progressively as the laying Aof the pipe continues and to prevent accidental slippage, ground-engaging spurs may be provided on the planks.

The pipe or pipe sections to be handled or laid may be like those suggested at 36 and are usually to be placed end to end. A section of the pipe is engaged from below by a plate 3l forming part of a sling completed by a flexible cable section 38 having hooks 39 flexibly connected to its ends and detachably engaged in `openings 40 of the plate 31. Such sling 31 is adapted to be detachably engaged by a hook 4I of a flexible suspending and manipulating cable 42 operable by a windlass 43 mounted on a carriage or conveyer 44.

The conveyer` or carriage 44 may be of any suitable construction and is shown as having a frame 45 including side members 46. `Axles 4'! are mounted transversely of the frame and are journaled therein and have wheels 48 keyed to the ends thereof. Such Wheels are peripherally grooved at 49 in order to engage and move along the rods II as tracks.

The aforesaid windlass 43 may consist of a f crank 52.

drum 50 carried by a shaft 5| journaled in the side members 46 and manually operable by a to the drum 5l). Fast on the drum 50 is a ratchet wheel 53 with which a pawl 54 pivoted to one of the frame members 4E coacts, to prevent retrograde movement of the drum. It will be realized that the pawl 54 may be. manually displaced if desired.

It is obvious that the structure may be built in any desired size andwith the'parts proportioned as desired to handle or accommodate various sizes of pipes or the equivalent.

I claim as my invention:

1. Apparatus for conveying pipe comprising ai framework having a body, a carriage movable on the body for the suspension of pipe therefrom, front and rear pairs of supporting legs pivotally attached to the body and intermediate the legs of which pairs the pipe is suspended, each pair of legs extending generally downwardly and outwardly from said body, said legs being unconnected and spaced apart attheir lower ends to avoid interference Jwith suspended pipe, and means relatively close to the pivots of the legs operable to vary0 the spreadiof the legs at the lower ends of the latter."

- 2. Apparatus for conveying pipe comprising a framework-,having a body,'a carriage movable on the body for .the suspension. ofV pipe therefrom, frontand rearl pairs of supporting .legs pivotally attached to thebody and intermediate thel'egs of which pairs the pipe is suspended, each pair Aof legs extending generally downwardly andeutwardly from said body, said legsbeing unconnected and spaced apart at their lower ends-to avoid interference with f suspended pipe, vand means relatively close to the pivots of the Vlegs operable to vary the spread of the :legs at'the One end of the cable 42 is fastenedr means relatively close tothe pivots of the legs operable to vary the spread of the legs at the lower ends of the latter, each leg consisting of upper and lower sections, and means connecting the lowersections to the upper sections for adjustment rotatably relatively thereto.

4. Apparatus for conveying pipe comprising a framework having a body, a carriage movable on the body for the suspension of pipe therefrom, front and rear pairs of supporting legs pivotally attached to the body and intermediate the legs of which lpairs the Ypipe is suspended, each pair of legs extending generally downwardly and outwardly from said body, said legs being uncon-V nected and spaced apart. at their lower ends to avoid interference ywith suspended pipe, and means relatively close to the pivots ofthe legs operable to varythe spread of the 4.legs at the' lower ends of the latter, forks at the lower ends of the legs, said forks having outwardly extending flanges adapted to rest on planks or the like in the absence of wheels, the forks having means to mount wheelslat a height torspace the flanges above the ground.
