SPECIFICATION forming part of Letters Patent No. 759,459, dated May 10, 1904.

Application filed August 12, 1903. Serial No. 169,165. (No model.)

vide a simple, light, inexpensive, and highly-.

efiicient truck having means for engaging and lifting a pipe, for supporting the latter during the transportation thereof without the liability of breaking, marring, or disfiguring the ware, and for resetting the same when the destination is reached with rapidity.

Other objects of the invention will appear and the many advantages of the same be appreciated when the invention is more fully disclosed.

To accomplish the ends sought, the invention includes the combination and arrangement of component parts and the details of construction to be hereinafter described, and particularly pointed out in the claims.

While the invention is susceptible of various modifications, the accompanying drawings illustrate and I'shall hereinafter describe in connection therewith what is now deemed to be the preferred embodiment of the same.

In the drawings, Figure 1 shows the truck in perspective. Fig.2 is a plan view thereof. Fig. 3 is a side elevation of the same, and Figs.

.4; and 5 are detail views of the clamping means for the pipe-supporting arms.

The improved truck includes generally a pair of supporting-wheels, a frame supported therefrom, and a pair of adjustable supporting-arms having engaging portions projecting in advance of said frame, and other portions guided and held in adjusted positions in the latter. i

The supporting-wheels are designated in the accompanying drawings by the letter a, and the main frame supported therefrom by the letter 6. The latter includes the side beams 0, suitably shaped at their rear ends to provide handles and connected at their front ends to the upper ends of vertical standards a, which latter are fixed at their lower ends to a cross-bar f, secured to the axle g of the wheels to. This frame also includes a cross.- head It, arranged parallel to the axle g and located above the ends of the standardse and front ends of the beams e. The frame is braced by crossing-bars m, fixed at their front ends in the bar f and at their opposite ends in the side beam 0, intermediate of the lengths of the latter. Between said beams c at this point a cross-beam n is arranged, to which is secured the rear ends of three bars 0, arranged parallel to the beam 0, but extending at an acute angle or obliquely in relation to the transverse plane of the same, the front ends of said bars 0 resting upon and being securedto a cross-bar p, suitably secured to the rear face of a cross-head 7L and constituting what might be termed a supplemental frame.

The supporting-arms s for the pipe are located one on each side of this supplemental frame and are held at their rear ends therein,

while the pipe-engaging portions thereof project in advance of the cross-head it.

In order that the engaging portions of the arms may be ad jllStGCl toward and from each Z other to accommodate pipe of varying diameters, the armsare preferably shiftable bodily transversely of the supplemental frame, this M action being secured by adjustably mounting While the con their rear ends in said frame. h nectrons between the arms and theframe may be secured in a variety of ways, the accom panying drawlngs illustrate a representative form of the same.

extending portion 8', which projects through transverse guiding-openings 1n the bars 0 and In this exempliiication the rear end of each arm s has a right-angularlyis engaged by a clamping member associated emplification of my invention (shown in the accompanying drawings) the devices 6 are associated with the opening a of the intermediate bar 0, and each of the former includes a ring having a threaded radially-projecting stem surmounted by an adjustable hand nut b. Each ring is guided in a recess or slot 10 extending through the bar 0, which intersects the transverse opening a, pertaining to said ring, and the upper side of the intermediate bar 0, in which the openings at and slots a are located, is provided with a wear-plate u, having openings through the same to accommodate the stems of the rings. The nuts threaded upon said stems find bearings upon the upper surface of said wear-plate, so that as said nuts are screwed home the rings will be drawn up to cross the transverse openings u pertaining to the same, and thus clamp the ends 8 of the arms 8. The engaging end of each arm 8 is preferably provided with a sleeve of soft cushioning material, while the front of the cross-head h and'the corresponding portions of the bar f are provided with cushioningstrips w. The arms 8, held at their rear ends in the bars 0, are supported intermediate of their lengths upon the upper face of the crosshead it, and to avoid undue jarring of said arms suitable cushioning-strips m are interposed between the bearing portion of the same and the cross-head, said strips being preferably secured to the upper side of the latter.

In using the truck the arms are adjusted inthe supplemental frame to separate the engaging surfaces thereof a distance substantially equal to the diameter of the exterior of the body of the pipe to be transported and when so adjusted are clamped in place, as premised. The truck is then slightly tilted by means of the handles and shoved toward the pipe until the cushion of the cross-head it strikes against the side thereof. The handles are then depressed, which will tilt the truck and raise the arms 8 into engagement with the under side of the collar of the pipe, and a continued tilting movement of the truck will lift the pipe clear of the ground, so that the same may be carried about. If the handles of the truck are sufficiently depressed, the pipe will swing upon the arms 8 until the lower part of the body portion thereof will rest against the cushion-strip on the barf, and as the upper part of the body portion rests against the strip on the cross-head and the pipe is held centrally at each side upon the arms 5' a firm support is given the same, which prevents the ware being marred in any way in carrying the same from place to place. By carrying the pipes in this manner it is not necessary to lift the pipe-boards, and not only is the wear thereon relieved, but fewer of the same are necessary.

The construction and operation of my invention will be readily understood upon reference to the foregoing description and accompanying drawings, and it will be appre ciated that the parts and combinations recited may be varied within a wide range without departing from the spirit and scope thereof.

Having thus described my invention, what is claimed as new, and desired to be secured by Letters Patent, is

1. In atruck for carrying sewer-pipe and in combination, a truck-frame, supportingwheels carried thereby, and non-pivotal supporting-arms adjustable tranversely of said frame independently of said wheels, said arms being held at their rear ends in said frame and having engaging portions projecting in advance thereof, substantially as described.

2. In a truck for carrying sewer-pipe and in combination, a truck-frame, supportingwheels carried thereby, and a pair of arms bodily adjustable transversely of the frame independently of the wheels, said arms having forwardly-projecting pipe-engaging portions and angularly-extending portions guided in the frame, substantially as described.

3. In a truck for transporting sewer-pipe and in combination, a truck-frame, supportingwheels carried thereby, a pair of arms adjustable bodily transversely of the frame inde pendently of the wheels, said arms having forwardly-projecting pipe-engaging portions and angularly-extending portions guided in said frame, and means for clamping the arms in adjusted positions, substantially as described.
