Application led .Tune 2, 1913. Serial No. 771,203.

To all '1r/1on1 t may concern Beit known that I, JONATHAN PERKINS, Jr., a citizen of the United States, and a resident of San Diego, county of San Diego, State of California, haveinvented a certain new and useful Gravity-.'\.ctuated Pipe-Laying Apparatus, of which the following is a specification.

My invention relates to an apparatus for handling and placing in position the different sections of pipe, preferably concrete pipe and the objects of my invention are, first, to provide an apparatus to facilitate the laying of large pipe, second, to provide such an apparatus that is simple, easily constructed and easily operated, and third, to provide such an apparatus in which the parts are adjustable for different sized pipe sections.

With these and other objects in view, as will appear hereinafter, my invention consists of certain novel features of construe tion, combination and arrangement of parts, as will he hereinafter described in detail and particularly set forth in the appended claims, reference heilig had to the accompanying drawings and to the characters of reference thereon, which form a part' of this specification, in which:

Figure l is a side elevational view of my device in the preferred form shown in connection with the pipe section with parts of the pipe hroken away and in section t0 facilitate the illustration, Fig. 2 is an end view of the pipe showing the tripod in p0sition, Fig. 3 is a side elevational View of my pipe carriage shown mounted on a fragmentary portion of this support and showing `a section of pipe mounted thereon in section, Fig. 4 is a top or plan view of a fragmentary portion of said carriage, Fig. 5 is a transverse sectional view taken through A-B of Fig. 3.

SimilarI characters of reference refer to similar parts throughout the several views.

The tripod l, carriage 2, carriage support 3, and jack 4, constitute the principal parts 'of my device..

The tripod 1, consists of a straight portion threaded almost its entire length and bifurcated at its top end 1n. t is mounted in a support l'b which is provided with an in ternal thread adapted to fit the thread on the screw on the main portion l. Over this thread in the main portion l is provided a nut l on Specification of Letters atent.

which are rigidly mounted at angles to said main portion 1, legs i@ and l whichl arend justaoly mounted in supports?. Mounted on this tripod in the slot between the hifurcated membersl is a T 'oar 3 adapted for the support for the carriage 2. @ver this support is mounted the 1cody portion 2 of the carriage, shaped as shown leest in Figs. 3 and 5. lt is provided with two longitudinal axis rollers 2l adapted for supporting the pipe section, which section may'.A he turned thereon. t is supported hy means of two transverse axis rollers 2 which are provided with flanges adapted to roll on the upper surface of the support 3 to reduce the friction of the movement of the carriage. The other end of the support from the tripod'is supported oy means of the jack t which is an ordinary jack except that it is provided with hifurcated top ends 4a adapted to fit the downwardly extending member of the support 3.

lt is obvious that with this apparatus there is provided a device that will greatly facilitate the placing ofthe different sections of pipe,

that by adjusting the tripod l to the proper A height, placing the support with the carriage thereon through the pipe sectionh placing a jack 4 under the other end and raising the simple of construction and easily operated.

Having thus described my invention, what l claim as-new and desire to secure by Letters Patent, is:

l. In a gravity actuated pipe laying apparatus an adjustable tripod, a normally horizontal bar with one end mounted thereon, a carriage mounted ou said har and prov vided with rollers to facilitate its movement thereon, horizontal aXis rollers mounted on said carriage so that their upper surfaces extend above said carriage and means for raising and lowering the other end of Said bar.

2. A gravity actuated pipe laying apparatus, comprising an adjustable tripod with hifurcated upper end, a normally horizontal T bar with one end mounted. thereon, a carriage mounted on said T bar and fitted riego 'provided with arouoe he seme and adapted to fravel =thereon, and a jack the upper end of which bfuroated to 'iig-said T ber for raising the end thereof. :i :j

3. A gravity` actuated -ppe laying appeetq, comprising a-tripod, each member o whlh s adjustable, a normally horizontal Darwith one end fmounted thereon, endlv adapted tozt the upger end thereof, a eerorizontal axis rollers,

lhounted enea-id bar and adapte to travel thereon, and a jock which is adapted to fri; said bar for raising the other end thereof.

In tespmony whereof, I have hereunto subscribed my name in the presence of two
