Specification of Letters Patent.

Application filed August 19,1918. Serial No. 251,040.
forms for surfacing piles and the like wherein semicircular sections operate in conjunction to form an annular channel around the pile to be surfaced; and the objects of my invention are First, to provide an improved form for surfacing partially submerged piles and the like ings forming a part of the present specification wherein llke characters of reference are used to designate similar parts throughout the said specification and drawings, and in 1 which Figure 1 is a partly. broken elevation of my improved form in position around a pile to be surfaced; i Fig. 2 is a broken view disclosing in ele- 'vation the upper portion of a form and the manner in which the sections thereof are de- I ta chably secured together;
Fig. 3 is a plan view of Fig. 2; and
Fig. 4 is a bottom view of Fig. 1.
\Vhere piles are partially submerged it is sometimes desired to surface said piles with a coating of cement or the like to pro tect their surfaces from the attacks of torpedoes and other marine insects.
l accomplish this coating of surfacing after the piles are in position readily placing and removing the sections of which the mold is formed without injury to the pile.
Referring to the drawings the numeral 1 is used to designate in general a form comprising vertically disposed cylindrical sections 2 open at the ends thereof and provided at each end with semicircular bands or hoops 3. Each end of each hoop or band 3 is provided with a notched lateral extension 4. which extensions lie adjacent to each otherwhen the sections 2 are assembled into a complete form 1.
A suitable latch 6 rests within the notches of the extensions t and is provided with a beveled recess 7 to engage and thereby retain the lateral extensions 1 and the sec tions 2 together.
By reason of the beveled or chamfered nature of the recess 7 of the latch the said latch may be easily removed to separate the sections 2.
The lower ends of each section 2 are each provided with a semicircular beveled flange 8 the adjoining flanges 8 of adjacent sections 2 operating to form a continuous internal annular flange, the purpose of which will hereinafter be more fully set forth.
The upper end of each section 2 is provided with a series of wedges 9 which operate in conjunction with separable wedges l0 and blocks 11 set against a pile 1 or other thing to be surfaced, to center tl e form 1 relatively to the said pile 12 whereby an annular channel may be provided between the interior surfaces of the sections and the exterior surface of the pile 12 or the like.
Each section 2 is also provided with an aperture 14, as disclosed in Fig. 1 of the drawings, and closable by means of a suitable plug 16.
In operation the device is as follows:
he completed form 1 consisting of the sections 2 is assembled around the pile 12 or the like by matching or registering the lateral extensions 4 of the bands or hoops 3 as disclosed in Figs. 2 and 3 of the drawings. The latches 6 are then inserted within the notches of the lateral extensions 4 to rigidly secure the sections 2 together.
Blocks 11 are placed against the pile 12 near the top of the sections 2 and the top of said sections. or the completed form 1, are centered with said pile 12 by driving in wedges 10 between the wedges 9 on the sections 2 and the blocks 11 against said pile 12, aS disclosed in Figs. 1 and 3 of the drawings.
I prefer to employ a suificient number of wedges to retain an annular channel of uniform width around the entire periphery of the pile 12 to be surfaced.
When placed in position the lower ends of the sections 2 are preferably placed below the low water line as disclosed in Fig. 1 of the drawings.
A grouting element consisting of a suitable fabric 17 filled with a mixture of proper proportions of sand and cement, 18 is placed within the sections 2 and upon the semicircular flanges 8 in the bottom thereof.
This grouting element is tamped or otherwise operated to center the lower portion of the sections 2 with the adjacent portion of the pile 12.
A second layer of sand and cement 18 of the requisite depth or amount is then placed in position and the plugs 16 are removed from the apertures l-l in the sections 2 to admit water above the grouting thereby equalizing the hydrostatic pressure above and below the grouting to prevent the pressure of water from below from displacing the grouting until it is set and sufliciently hard to serve as a support for the surfacing to be applied later.
After the grouting element has set the plugs 16 are reinserted within the holes 1% and the water pumped from the interior channel between the pile 12 and the interior of the form 1. A surfacing mixture of concrete or cement is then poured into the mold to fill the channel and after said surfacing mixture has hardened or set the sections 2 are easily and readily removed by detaching the latches 6, removing the wedges 10 and blocks 11, and then separating and removing the sections 2 from the hardened surface.
By removing the grouting support or flange 8 from the bottom of the sections 2 it is evident that said sections may be superimposed one upon the other to build up a surface of any desired length or height.
Having thus described'my invention what I claim as new and desire to secure by Letters Patent is 1. A surfacing mold for piles and the like comprising matched semicircular sections; means for centering one end of the matched molds relatively to a pile; and means for supporting a grouting element at the other ends of the matched sections.
2. A surfacing mold for piles and the like comprising vertically disposed semicircular sections; means for centering the upper ends of the sections relatively to a pile; means for supporting a grouting element at the lower ends of the sections and around the pile to be surfaced; and means for equalizing a hydrostatic pressure above and below a grouting placed upon the supporting means to retain said grouting in position.
3. A surfacing mold for piles and the like comprising vertically disposed semicircular sections; means for centering the upper ends of the sections to a pile; means for supporting a. grouting element at the lower ends of the sections and around the pile to be surfaced; means for equalizing a hydrostatic pressure above and below a grouting placed upon the supporting means to retain said grouting in position; and means for detachably retaining the sections together. 7
i. A surfacing mold for piles and the like comprising a pair of matched, vertically disposed semicircular sections; means for detachably securing the sections together; suit able wedges for centering the upper ends of the sections relatively to a pile to be surfaced; a semicircular beveled flange secured within the lower end of each section to support a grouting element around the pile; and means for equalizing hydrostatic pressure above and below the grouting.
5. A surfacing mold for piles and the like comprising a pair of vertically disposed semicircular sections having apertures therein to permit the passage of water when said molds are submerged; semicircular hoops secured to the molds and having notched adjacent ends; suitable latches arranged to engage the ends of the hoops and thereby detachably retain the sections together; suitable wedges arranged tocenter the top of the sections relatively to the pile to be surfaced; and a semicircular beveled flange secured within the bottom of each mold to support a grouting element around the pile.
In witness whereof I hereunto set my signature.
