To all whom it may concern:

Be it known that we, FREDERICK M. WHITE and HENRY E. RIEGER, citizens of the United States, residing at San Diego, in the county of San Diego and State of California, have crete of suitable thickness may be formed around a pile which is partially submerged so that the concrete layer will extend some distance into the ground and above the surface of the water; second,'to provide an apparatus of this class by the use of which the concrete may be mixed and poured above the surface of the water and lowered in position.

around the pile to the position desired; third, to provide an apparatus of this class which prevents contact of the water from the outside with the concrete thus providing a concrete shell around the pile which is of uniform thickness and hardness; fourth, to provide an apparatus of this class which is easily and readily removed after the concrete has been allowed to set sufliciently; and fifth, to provide an apparatus of this class which is simple and economical of construction, durable, easy to operate, easy to install and will not readily get out of order.

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

Figure 1 is a perspective View of a fragmentary portion of a driven pile and showing encircling the same the layer of concrete and showing a fragmentary portion of our apparatus positioned thereon. Fig. 2 is a perspective view of several fragmentary portions of the forms showing the means for joiningthe separate form members together. Fig. 3 is an inside elevational view of two of the lower trap members. Fig. 4 is atop view thereof. Fig. 5 is a side elevational view ofa fragmentary portion of the upper ends of the form members 3, and Fig. 6 -isa perspective view of the key for connecting the different form members together.

Similar charactersof reference refer to similar parts throughout the several views.

The rigid trap members 1, mold members 2, mold members 3, releasing rods 4, key members 5, vertical gaskets 6, horizontal gaskets 7, flexible trap members8, cables 9 and cables 10 constitute the principal parts of our apparatus.

The rigid trap members 1 are quadrant in form so that four of them when connected together form an annular plate. They each consist of a quadrant shaped metallic plate 1 and each is provided on its outer surface with an angle lug 1 the one member of which is secured to said plate 1 and the other -member extends therefrom and is provided with a slotted hole 1 therein. On the other edge of the plate is secured a similar lug 1 which is provided with a U shaped lug 1 on its extended member adapted to fit into the hole 1 in one ofthe lugs 1 on another of the mold members 1 and one of the key members 5 is inserted therein for securing said mold members together and mounted between the adjacent edges of the molding members 1 are gaskets l which are preferably the combination of rubber and canvas to provide strength and pliability. These key members 5 connecting the members 1 together are removed by the cable 9 which connects with them so as to pull one and then the other of said keys 5. Secured in the middle near the lower edge of each of the said members 1 is a U shaped lug 1 in which is mounted a ring 1 and mounted in the middle near. the top edge of each of said members 1 is a lug 1 which is provided with a hole therethrough for the pin 2 for connecting the

sections

1 and 2 together. Mounted on the inner surface of each of the members 1 is an angle bar 1 the one member of which is secured to the inner surface of said mold member 1 and the other member extends inwardly and upon the top, surface of which is secured one of the flexible trap members 8, the inner edge of which extends considerably past the inner edge of the angle member and one end of said flexible trap member 8 ext-ends past the end of said angle member so that it over-laps a similar member on an adjoining trap member. These flexible trap members 8 are preferably composed of a compositionxof rubber and canvas to provide strength, durability and flexibility.

The mold members 2 consist of semi-circulugs 292Wl1i0h areyadapted to fit in "said oblong-holes and extend through the .same and :between the angle ,barand the extended portion of said lug is mounted one ofthe key members 5 inqeach of,sai d.U,shaped lugs.

' Mounted between the ;angle bars 27? on; the separate hitlVGSriLlIB vertical) gasket 6 which provide a .water tight ifitg between said angle bars Secured to the lIIIIQINSllIfitCQOiE said plate-2 at the lowerside thereof is metallic *1Jiece :2 which extends downwardly into the trap members and for reinforcingiand making a tight joint. :Mounted near thelower sides of said. mold members .2 are bifurcated 'lugsfl which are providedwith slots there in adaptedfor the "pins 2 so that the lugs 231 1? and :pin: 2? form hinges for pivotally connecting the members 1 ,and 2itogether which, however, will release whenthe members 1 are turned;upwardly'thereonw Mounted between the adjacent edges are gaskets 7 for forming awater-tight joint between said members. Mounted'inthemiddle of eachof the form members .2 nearthe top arehook shaped-lugs 2 adapted for a hitch for-cables 10, one; on each 'side of the pile for guiding and supporting said forms aroundlthe pilekas it movesdownwardly as each section is filled with concrete between the forms and the driven pile The concrete we have marked A and the pile B to facilitate the illustrationw I A The form members 3 which comprise the remaining form members are: shaped and constructed'tthe same :as the member-2 except that on the lower edge there is mounted an angle bar as well as on thewtop and side edges and the; j oints between the :

members

2 and 3 are (formed byimean'sxof theholes B and U shaped lugs Qfizandonesbf thelkeys 5 1 driven therein there being a gasket :7 betweenthe two horizontal" angle :bars :andnthe pieces 2. are not placed thereon. In order to remove the 'keys 5 along the vertical angle bars :there are provided rods a which extend through --the links connected to said keys and the lower: endsllof-fsaid rods 4 are provided with bonds 14? therein so-thatlsthe said keys may be'removed by .raising'said rods 4;, the upper en'd of which extends above thetop 'ofthe-water; Though we have-shown and-idescribed a particular construction, combination and arrangement of parts we do not wish to be limited tovithis particular. construction, combination and arrangement, but desire to includein'the "purview of our: invention the construction, combination and arrangement substantially as set forth in the appended claims; a

The operation of the apparatus is as follows: The trap members 1 are connected together around-the pileaboye the surface of the'water and secured by means of keys in the ,U' lugs .1 the inner edgerof the flexible trap members'S are bent upwardly, and fit snuglyaround the pile. WThe two members tween the pile and forms is filled with con-v crete the-lowerv edge supported on the trap membersfig hen ,the forms 21are nearly full the forms 3 aresecured to the top edge thereof, by means of the keys and lugs through the .anglebars and the two members are secured together byineans of the keys in the lugs along the vertical tangle bars. Thenthe loWer members are lowered nto the water and the sections 3 filled and smonuntil the trap-members 1 reach the ground swhen' the keys securingzsaid trap members together are removed by means of the cables 9 andthe lower edgeof the trap section is turned upwardlyuon the pins 2 whichreleases the trap members at-the bot-.

gtomand the plate Qf together with the ,con- ,crete isallowed to sink into the ground around said pile, the weight of ,the layer of concrete and pile forcing the same into the ground'some distance. After the concrete has-set sufiiciently the keys along the yertical angle bars are-removedby means of the rods and the lower members .2 and?) are thenraisedwto the surface of the water by meansiof the cable 10, the members-3 being removed by removingcthe keys after the jointsIare raisedto above the surfaceof the water-thus leavinga layer vof concrete around the pile from some ,distance below the top of the ground to abovethe surface of the water;

it is obvrious-that with the above apparatusrthere is provideda means :Whereby a layer of.- concrete; may be lowered around wooden er .other pi'les driven into the ground and rin s everal ieet' of water, that the molds 1and-join ts are so constructed .that the water from the outside cannot-get ,through to the concrete gsufiicient quantity to injure it until it hasset-,-;that thedifferent mold sections are readily assembled and may be readily disassembled although submerged, that the apparatus as a whole is simple and economical of construction, durable, easy to operate and will not readily get out of order.
