  • This invention relates to improvements in caps for metal sheet piling, and has for its object to provide a suitable cap to be used in driving a piling to keep the piles in alinernent and to protect the ends of the piles from injury.
  • Figure 1 is a top plan view of my improved cap.
  • Fig. 2 is a bottom plan view thereof.
  • 3 is a. transverse section on the line 3 of Fig. 1.
  • Fig. 4 is a top plan viewof a portion of the cap.
  • Fig. 5 is a side elevation of the cap shown in Fig. 4.
  • -Fig. 6 is aplan view showing two sections of the sheet piling with the cap in position for driving the same, the cap and the driven pile being indicated in dotted lines.
  • Figr-7. is an end-elevation of a pile driver, showing the method of using the cap.
  • sheet metal piling is made in sections composed usually of a web portion provided at its ends with interlocking devices. Such a pile is shown In the specific form shown in Fig. 6,
  • I 1' indicates the web portion of the pile, f a recessed end portion,fand f a slotted end adapted to enter the recessed portionrof the adjacent pile, as indicated in this figure.
  • These piles are used in the construction of sea-walls, docks, .coffebdams, bridge-pier foundations, and in work of similar character, and it is desirable in driving them to provide some means for pre-, venting injury to the endsof the piles from the force oltthe blow delivered thereon by the hammer of the pile-driver and also to provide some means for holding the pile being driven in alinement with the adjacent driven pile.
  • I provide, therefore, a. follower-cap a, shown particularly in Figs. 1, 2 and 3.
  • This cap is composed of a block of suitable material having guide recesses c to engage the standard b of the pile-driver, and this block is provided on its under side with recesses e having ends e the recesses e, e being of a shape corresponding with the transverse section of the pile.
  • the block is provided on its opposite face with a recess e adapted to receive a wooden block or a block of some elastic material which will absorb some of the shock of the blow and-prevent injury to the cap. When in use the cap is placed upon the end of the pile to be driven.
  • the driving cap may be utilized either when the pile-driver is. located at'jthe side or the end or the sheet piling wall, the particular position of the pile-driver .relative to the wall of sheet piling depending upon the character of the work, whether upon land or water, and upon whether the pile-driver. itself is mounted upon a floating structure or upon land..
  • I provide the driving cap with two sockets, one at right angles to the other.
  • a block h having a plain lower face h and an upper face provided with projections k h respectively corresponding in shape to the recesses -e, e of the upper block.
  • This lower block being placed on the corner-piles, the upper block is placed thereon with its recesses engaging the projections and.
  • thecorner-pile driven as will be readily understood.
  • the lower block may be so placed that either of its ribs or projections may engage with either of the recesses in the upper block.
  • the blocks are provided with passages or perforations e, h through which a rope 9 may be passed for the purpose of lifting the blocks.
  • a cup for sheet-metal piling comprising a block having recesses on one face on'each diameter, each recess corresponding in shape to the transverse section of a pile, and a second block having projections adapted to enter the recesses.
  • a cup for sheet-metal plling comprising an upper block having recesses on one fucecorrespondlng in shape to the transverse section of a pile, and nlower block ln vlug. a plain face adapted to rest on the pile and provided on its opposlte face with projections entering the recesses in the upper block.
  • a cap'tor sheet-piling comprising a block having two recesses in one face thereof, said recesses being disposed at an angle to each other and each of said recesses conforming substantially to the cross section of a pile.
  • a cap for sheet piling comprising a block having guides at its sides, and having two recesses in its lower face, said recesses being disposed at an angle to each other and each of said recesses conforming substantially to the'cross section of a pile.
  • a cap for interlocking sheet piling comprising a block having a recess extending completely across one face 1 thereof, said recess being of such form asto embrace the end of a pile being driven and the interlocking part of the previously driven pile.
