PONTOON-SUPPORTED DERRICK.

-App1ication filed August 22,1922. Serial No. 583,547.

To all whom it may concern Be it known that I, CHARLES L. LoNsrNo- ER, a citizen of the United States, residing at VValhonding, in the county of Coshocton, State of Ohio, have invented a new and useful Pontoon-Supported Derrick; and-ll do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the. art to which it appertains to make and use the same.

The invention relates to pontoon supported derricks, and-has for its object to provide a derrick particularly adapted for use for drilling oil wells, said derrick being of a knock-down type, thereby allowing the Same to be stored within the pontoon.

A further'object is to provide a derrick support comprising spaced pontoons in parallel relation to each other, said pontoons being provided with yoke members for rigid- 1 connecting the pontoons together. The (l errick is supported centrally between the pontoons with its supports and braces attached to the upper sides of the yokes. The pontoons form means for preventing swaying of the derrick during the drillingor casing driving operation and also forming a support for the derrick, which when the derrick is disassembled, and the pontoons separated, may pass through narrow laces such for instance as canals, under brldges, or may be easily shipped over land.

A further objectv isto provide one end of one of the pontoons with an engine adapted to be utilized during a well drilling operation. The power for said engine is obtained from a pipe leading to a boiler located on a separate pontoon located at a remote point from thederrick, thereby obviating explosions and fire incident to the well drilling operation.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:-

Figure 1 is a side elevation of the pontoon supported derrick, showing a boiler supported on a separate pontoon.

Figure 2 is a top plan View of the device.

the operation.

Figure 3 is an end-view of the pontoon showing a portion of the derrick.

Figure 4 is a,detail perspective view of one end of one of the yokes.

Referring to the drawings, the numeral 1 designates spaced pontoons which are in parallel relation to each other. The pontoons 1 are held in spaced parallel relation by means of yokes 2, which extend transversely of the pontoons. Each yoke 2 comprises a transversely disposed bar 3, which engages the upper sides of the pontoons 1 and segmentally shaped members 4, which engage under the bottomsof the pontoons and have their ends detachably connected at 5 and 6 adjacent the inner and outer'sides of the pontoons, thereby rigidly holding the pontoons in spaced parallel relation.

versely disposed bars 3 is a derrick 8 of a knock-down type, which derrick is centered over the space 9 between'the pontoons 1 and is also centered in relation to the ends of the pontoons, thereby preventing listing of rick, which supporting base will prevent.

swaying of the derrick, and at the same time when the derrick is disassembled and placed in one of the holds 12 of the pontoons through the hatches 13 that is, after the yokes 2 have also been disassembled and stored in the holds 12, the pontoons may be easily moved through narrow places, such for instance as canals, or under bridges, and particularly through shoal-water, and if so desired shipped over land.

Disposed on one end of one of the pontoons 1 is a steam engine 14, which engine may be utilized for operating mechanism during the drilling or casing driving or pulling operation. The engine 14 is'supplied with steam from a boiler 15 located on a pontoon 16, which is remote to the derrick 8, thereby preventing ignition of gases and consequent explosion and fire, the ignitinn of the gases being caused by fire under Detach-' ably connected at 7 to the central transthe boiler 15. Steam passes from the boiler 15 to the engine 14 throu h the pipe 17, which pipe passes over a sma l pontoon 18 which is connected at 19 to the pontoon 16 and to one of the pontoons 1. Pontoon 18 forms a walkway over which workmen may pass to and from the pontoon 16.

From the above it will be seen that pontoon supported derrick is provided which is simple in construction, and that may be easily shifted or moved bodily as a whole from place to place or may be easily disassembled for shipping or storage purposes, and that the pontoon will prevent swaying or moving of the derrick, and at thesame time when the derrick is disassembled and stored within the pontoons, said pontoons may be passed t h rough canals and other narrow waterways.

The invention having been set forth what is claimed as new and useful is l 1.- The combination with a well derrick, of means for'supporting said derrick on water, said means comprising a base, said base being formed from spaced pontoons in parallel relation to each other, said pontoons having their upper sides fiat and their under sides convexed, transversely disposed yokes connecting said pontoons together, said yokes comprising bars engaging the upper fiat sides of the pontoons, segmentally shaped members arching the undersides of the pontoons, the ends of said segmentally shaped members being detachably connected to the bars adjacent the sides of the pontoons.

2. A well drilling derrick adapted to be alle relation to each other, t e upper side of the pontoons being fiat, transversely dillposed bars disposed on the upper flat sides of the pontoons and extending across both pontoons, U-shaped bands arching the undersupported on water, spaced ontoons in parsides of the pontoons and having their ends detachably connectedto the bars adjacent the opposite sides of the. pontoons, said derrick being centrally disposed on the base formed by the pontoons and detac-hably con-
