BULKHEAD.
Speccation of Letters Patent.

Application led May 22,1905. Serial No. 261.725. r
tion, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to bulkheads for closing the ends of large pipes; and the object of my invention is to facilitate the laying of large pipes under water by closing the ends of the pipe with bulkheads, utilizing the buoyancy of the inclosed air in supporting the pipe and dispensing with the use of any outside iioats while the pipe is being lowered and placed in position, the adjustable bulkhead being used in conjunction with a simple bulkhead in the opposite end of the pipe having a valve attachment for letting water into the pipe or pumping water out. I attain these objects with the mechanism illustrated in the accompanying drawings, in which- Figure l is a section of the bulkhead in the line A A, Fig. 2. Fig. 2 is a plan of the bulkhead With part of the operating-wheel broken off. Fig. 3 is a pipe-joint, shown partly in section and showing the bulkhead in place. Fig. 4 is a sectional elevation of the bell of ipe-section and both end portions of anot er pipe section having its ends sealed by the expansible bulkhead and by a simple or outer bulkhead.
Similar vcharacters refer to similar parts throughout the several views.
o is the iXed part of the bulkhead, constructed of light wood to give buoyancy, and is made of somewhat less diameter than the a and b are segments of the adjustable part of the bulkhead, also made of wood or light material and cut to the circle of the interior of the pipe.
c c are dogs, of steel or otherl metal, fastened to the segments a, and t and designed to bear against the ends of the pipe and sustain the pressure of the water on the outside of the bulkhead.
e e are guides for holding the back ends of the `dogs c c.
d d are adjustable arms for operating the segments and .are attached at their inner ends to the nut f, operated by the screw g. The arms d are rendered longitudinally adjustable, preferably by being formed in sections united by turnbuckles, about as shown. The arms operating segments a, a are attached to the nut f higher up than those operating sectionsb b, causing sections a c to move toward the center more rapidly than the sections t b.
K is a packing of rubber or other suitable y material.
l and m are joints to be fitted with pack-l ing, if necessary.
In Fig. 4 I show a pipe-section as though sunk with its spigot end inserted in the bell of a previouslylaid pipe and showing the bulkheads therein and ready for removal. The outer or simple bulkhead 2, of any suitable construction, is removably secured by suitable means against the end edge of the bell end of the pipe-section. The solid or outer bulkhead 2 is provided with pipe connections 8, extending therethrough and having suitable stop-cocks or valves 4, whereby water can be admitted to the interior of the pipe-section for gradually sinking the same, or whereby water can be pumped therefrom when it is desired to raise a sunken pipe-section, or for other purposes.
The usual method of operation would be after several sections of pipe have been jointed together on shore to place this bulkhead in position in the spigot end, carefully adjusting it toV make it water-ti ht, and place the simple bulkhead in the begll or opposite end, then launch the pipe and ioat it to position, and thereby letting some water into the pipe to sink it to place in the trench and enter the spigot end into the pipe already laid as far as the dogs will permit. This will be seen to be sufficient (by referring to Fig. 3) to permit of calking the joint. The joint can then be calked in the usual way. When this is completed, the diver removes the outer bulkhead and then entering the pipe releases and removes the adjustable bulkhead.
What I claim as `my invention, and desire to secure by Letters Patent, is- Y j 1. A pipe-section, in combinationwith a removable bulkhead tting against and clos- IOO ing one end thereof, and a bulkhead Within and closing the opposite end thereof vand removable through the pipe-section and provided With adjustable outwardly-projecting stops lapping the end edge thereof for maintaining the bulkhead in place against the Water-pressure.
2. A pipe-section, in combination With Ya removable bulkhead adapted to fit Within and close the spigot end of said section and provided With radially-adjustable stops for provided with longitudinally-extending sto )s to la a shoulder of the pipe to maintain t e bulkliead against the Water pressure.
4. A pipe-section, in combination With an expansible bulkhead provided With operating means and forming an approximately Watertight closure for an end of the section and provided with stops lapping the end edge of the section, substantially as described.
5. A pipe-section, in combination With an expansible bulkhead arranged Within one end of the pipe-section and provided With operating means at its inner side and Within the pipe-section, and with stops projecting beyond its outer side to lap the end edge of the section, substantially as described.
6. A pipe-section having a spigot end, in combination with a bulkhead located. Within said end and forming an approximately Watertight closure for said end and provided with stops lapping the outer edge of said end, substantial y as described.
7. A bulkhead comprising movable segments, operating means therefor, and dogs or stops carried by the segments and adapted to lap the end edge of a pipe-section.
8. An expansible bulkhead adapted to fit Within and expand against the inner surface of the end of a pipe-section, and provided With o erating means, and with dogs to lap over t e end edge of said section, substantially as described.
9. A bulkhead comprising a body or disk, overlapping edge segments, means for adjusting said segments radially to increase or diminish the diameter of the bulkhead comprising mechanism whereby said segments move at different rates of speed, substantially as described.
10. A bulkhead comprising a main body or disk, edge segments sliding radially thereon and provided With packing at their outer edges, and adjusting means connected With the segments for simultaneously j adjusting them radially on said disk for varying the diameter of the bulkhead.

12. A bulkhead comprising a main body or disk, edge segments movable radially and overlapping at their ends and forming the periphery of the bulkhead, and means for simultaneously moving all of the segments radially and for moving certain segments at a different rate of speed from the remaining segments, substantially as described.
13. A bulkhead comprising a disk, radially movable edge segments overlapping at their ends and slidable on the side face of the disk and projecting beyond the edge thereof, and adjusting means carried by the disk and connected With said segments for simultaneously moving them radially to vary the diameter of the bulkhead.
