To all whom it may concern:
Be it known that I, OMAR A. STEMPEL, a citizen of' the United States of America, residing at Clearwater, in the county of Hillsboro and State of Florida, have invented new and useful Improvements in Molds, of which the following as specification.
Thisinvention relatesto improvements in molds of the typeshown' in my prior U. S. Patent No. 784,967, granted March 14, 1.905, desigried to used in the construction of a protecting jacket or covering of con- Crete r h i sist d ia about Pile t egraph poles and lilge to preserve the sanre from dey D n t 'e b e e fi e a d Q cau s which lead torapid deterioration and d estruction e f i th s ch m??- li sid a also a e for rise in forming concrete clesf bf a sim pane- Th present invention has for its primary object to som a seam e s wh h so ve ed 1 diameter to suit differentcontingencies of service, nd Wh s ar be 3 a dled ipped ri quickly and conveniently assembled and "disasse n bled.

:mene ifl a te e the e of solid piles, .filers and other structures ofconcrete varying to a greater or less extent in diameter.
In Fig. 8 a mold embodying four sections, 1, 1, 2 and 2' is shown, and any number of such sections of proper partially-circular form may be used and assembled in the manner hereinafter described to produce a mold of the desired diameter. The sections used in conjunction with each other are similar in construction and of any desired length, and each has its longitudinal'side edges folded outwardly to form reinforcing flanges 3. Metallic joint plates 4, extending the full length of the sections, are attached toeach sect-ion adjacent the reinforcing flanges 3, and each joint plate'is bent outwardly and inwardly to form a longitudinal groove or receiving space 5, and thence outwardly and laterally to provide diately bent portions thereof formihgthe grooves or recesses have their outer walls disposed in parallel relation to the flanges 3. The grooves or receiving spaces 5 in the adjacent meeting edges of the mold seemy 8? 9 iv th re to: i
quired strength an d stiffnessthere- The edge of bne strip is inserted and fastened w hin the receiving space ispreferably fitted at its opposite end into the receivingspace of the other section, this arrangement being reversed atthe opposite sides of the mold, these ction l provided with one of the strips which is per- I l o, while the other strip is permanently fastened upon the section 2 Each strip is fastened in position rows of riyets 9 extending threu g h the same and the parallel inner and outer walls of the receiying portions Transverse bracing strips 9 are riveted or otherwise fastened to the mold sections andv overlap the plates 4 to increase the strength of the structure. I V I The mold sections are adapted to be held in assembled position longitudinally sliclable clamps or unions 10, each comprising an outer body plate l l extending the full length thereof, and upon the inner side of'whi ch are arranged transverse strips 12 projecting at their ends beyond said body plates and bent to their construction and mode of application permit the plate 11, which is sufficiently flexible, to bend freely in one of the sections, and
- provide hooks 13 to engage the tongues 6. The strips 12 are fastened to the plate 11 by rivets 13, and by mold may n a plane at right angles to the strips, thus forming in effect, without the use of hinges, a jointed clamp which may be bent outwardly to facilitate its insertion and removal clear low piers or docks in the use of the mold-upon one of the piles or supports thereof. Each clamp or union is provided at its upper end with a handle 14 for convenience in raising, lowering and manipulating the same, and, in order to secure a tight connection between the mold sections, the flanges 6' and hooked edges 13,- which form tongue and groove connections between the mold sections and clamps, are tapered longitudinally of the mold, so that in the action of applying the clamps the mold sections will be drawn together by a, wedging action. The taper of the interlocking parts increases gradually from the upperto the lower ends of the mold sections and clamps, thus allowing the lower ends of the clamps to be conveniently applied to the upper portionsoLthe tongues 6 and the clamps to be thereby freely slid down into locking position and to gradually draw the mold sections together as they are forced downward.
The mold sections may be constructed of sheet metal or any other suitable material and are provided at their upper ends with handles 15 to enable them to be supported and adjusted'by ropes or other supporting devices.
In employing the mold for forming a protective covering about a submerged pile or similar support, the
mold sections are lowered into the water on opposite.
sides of the pile and then brought into operative position, after which the clamps 10 are applied to hold the mold sections in position about the pile. end of the mold may then be forced into the ground or bed of the stream in any preferred manner, and centered about the pile, thus forming a chamber around the pile which may be freed from water by pumping, the water-tight joints preventing further access of water thereto. Ait'er the mold has thus been applied in position it is filled with a concrete mi able character and the mold allowed to remain in po- I or hardened. The
sition until such mixture has set 10 upwardly to release them-from the sections 1 and 2, after which the latter may be drawn out of the water. As a result the pilewill be provided with an'impervious coating of cement which will protect the same from rust or seam the ravages of teredos, water bugs and other destructive insects, and from decay from natural causes. The mold may also be employed in an obvious manner for constructing solid piles, piers and other elements of this nature of concrete or other plastic materials.
By constructing the mold in -the manner described the sections thereof may be conveniently fitted into one another or nested for storage or shipment, and by the described construction of the clamp ample flexibilityof the same is secured to enable them to be fitted in positionupon mold sections arrangedabout one of the supporting piles or a low wharf or pier without the necessity of employing hinged joints. I
The mold sections may be made of any desired length, and by making the sections separable the mold may be more conveniently applied for use and removed, and the sectional construction also enables the and to adapt the upper end thereof to The lower xture of a suitthen be disconnected by drawing the clamps.
mold to be placed around any pile irrespective of its position relative to an overhead covering, wharf or pier which would prevent a permanently closed tube from being placed about the pile.
An important feature of my invention resides in the peculiar construction of the joint connections or means for securing the mold sections together, it being noted that while the body portions or plates of the unions are uniform in width between the edges of the hooks 13, the latter, as well as the tongues 6 of the mold sections, taper gradually and uniformly, whereby in the operation of applying the unions the increased width of the hooks at the lower ends thereof allows the unions to be freely fitted in position, while in the operation of disconnecting the unions such construction permits the unions, after they have been drawn upward to a slight extent to decrease the friction between them and the tongues, to be disengaged with case from the tongues to disconnect the mold sections. Furthermore, the mode of constructing the unions employed in the present instance insures freedom from binding or hang,- ing, such as is experienced in the construction of the unions of hinged sections, and a much securer watertight connection is'afforded. The peculiar construction of the packing 8 also provides an absolutely watertight joint without the use of complicated fastenings and *without the necessity of bringing the meeting 1 edges of the mold sections into direct contact, as the pressure of any water which may creep past the unions and enter the packing space will crowd the packing against the flanges 3, thus preventing the entrance of the water to the mold. y
In Fig. 5 I have shown the mold arranged about one, of the piles B of a wharf, pier or similar structure 0, from which it will be observed that the flexibility of the unions permits them to be readily applied to and removed from the mold sections by a bending'action' below the wharf and without interference In the operation of assembling the mold sections, they may b e lowered into the water by ropes or other sup, ports applied to the rings 15 and held suspended above the bottom or bed of the river or other body of water. while the unions are being applied, after which the mold is lowered, forced down into the bed and freed from water in the. manner before described. The construction of the joint iastenings iorini'n'g the mold, as it is simply the packing strips into the recesses at the upper ends of the mold sections and to apply the unions without the necessity of fitting the strips in position throughout the length of the mold sections, as the downward movement of the unions will bring the meeting edges of the mold sections together and accurately ing stri-ps into their receiving recesses.
. If desired, the edges of the tongues 6 may be straight instead of tapered, in which event a longitudinally tapered packing strip 8, shown in Fig. 9, is used to secure a'close joint between the sections when drawn together by the tapered locking members on the union.
Having thus described what is claimed as newjis:-
1. A mold comprising a plurality of sections provided at their meeting edges with receiving spaces, packing the invention,
facilitates the work ofnecessary. to insert,
therefrom force the packs with a stay embedded therein, and unions connecting the meeting edges of the sections.
2. A mold comprising a plurality of sections provided at their meeting'edges with receiving spaces. packing strips, each having one edge fastened within a receiving extend into the receiving space of the other section, and unions uniting the meeting edges of the sections.
3. A mold of cylindrical form comprising a pluralityof partially circular sections provided with receiving spaces and locking tongues extending longitudinally along their meeting edges, flexible sliding unions engaging said tongues crossing the joints between the sections between the meeting edges of the latter and the unions, each strip being ranged to cross the joints between the sections and to hold the meeting edges thereof separated to permitcompression of said strips, and flexible sliding unions engaging the locking tongues and adapted to draw the meeting edges together to compress said strips, said unions being arranged to close the spaces outside the strips and to cover the outer exposed surface of the latter.
6. A mold comprising a plurality of separable sections. each section being provided at its edges with receiving ,spaces and locking elements, packing strips seated in said receiving recesses, the strips being respectively permanently fastened to the different sections and removably projecting into the receiving spaces of the opposing sections, and sliding means engaging the locking elements to hold the meeting edges of the sections united.
7. A mold comprising a plurality of separable sections, each of said sections being provided at its meeting edges with portions bent outwardly and laterally to form a longitudinal receiving recess and rebent laterally in the reverse direction to provide a locking tongue located outthe free edges of the packing strips projecting into the normally unoccupied recesses of the sections, said strips being arranged to hold the meeting edges of the sections spaced apart and crossing and closing the intervening joints, and flexible sliding unions engaging the locking In testimony whereof, I affix my signature in presence of two Witnesses.
