10 Claims.'

'I'his invention relates to an improved guide member for use in driving sheet piling, such as the interlocking sheet piling which is commonly employed in forming breakwaters, coer-dams and the like, and the present application is a division of my co-pending application, Serial No. 725,491, filed May 14, 1934, now Patent 2,057,947 of October 20, 1936, in which there is described and claimed an improved method of driving sheet piling to form such structures, according to which sheet piles are interlocked with each other to form a plurality of separate panels or sections which are then moved to the place where they are to be driven and spaced apart along their lateral edges in vertical positions to be connected by intermediate connecting sheet piles preliminary to driving all of the piles into the bed of the river or harbor in which the structure is to be formed. In the practice of thatimproved method, the separate panels or sections of sheet piling are spaced apart by clamps or spacing devices which form the subject-matter of my co-pending application, Serial No. 17,401, led April 25, 1935, and these spacing devices which detachably engage the lateral edges of the panels are removed prior to or during the process of driving the intermediate connecting sheet piles which secure adjacent panels together.

The principal object of the present invention is to provide an improved guide member adapted to be mounted upon the upper ends of adjacent sheet piles which are spaced apart and which are to be connected by an intermediate sheet pile and the function of the guide member is to direct the intermediate sheet pile into proper interlocking engagement with the spaced piles to be connected thereby at the commencement of the operation of driving the intermediate pile. A further object of the invention is to provide an improved guide member adapted to be detachably mounted upon the upper end of a sheet pile for directing the lateral edges of two sheet piles into proper interlocking engagement with each other when one pile is driven with respect to the other. Still another object of the invention is to provide an improved guide member having parts for detachably engaging a pile and having a projecting guide portion adapted to coact with one of the interlocking parts of an adjacent sheet pile when the latter pile is brought into engagement with the pile in which the guide member is mounted. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specication taken with the accompanying drawings,.in which one embodiment is illustrated.

In the drawings,

Fig. 1 shows an enlarged vertical section through a portion of a breakwater or the like illustrating the method of driving sheet piling according to the invention of applicant's said original application and illustrating the use of the improved guide member of the present invention;

Fig. 2 shows an enlarged horizontal section on the line 2-2 of Fig. 1, illustrating two of the guide members of the present invention which are employed for guiding a connecting pile when this pile is driven into interlocking engagement with the end piles of two adjacent sections or panels;

Fig. 3 is a perspective view of one of the improved guide members of the present invention; and

Fig. 4 shows an elevation of one of the guide members illustrated in Fig. 2, together with p0rtions of the adjacent sheet piles.

In Fig. 1 of the drawings there is shown a portion of a breakwater I 5 which is being constructed according to applicants invention by driving a left of Fig. 1, there is shown a portion of the side wall 20c of one of the sections of the breakwater and this side wall is connected to an opposite side wall by a transverse wall 20h, all of these walls being formed of similar sheet piles which interlock with each other at their edges. At the junction of the side wall section with the transverse wall section, there is a connecting sheet pile 2| of triangular cross-section having a ilange which is adapted to interlock with the side wall of the next adjacent breakwater section, which is shown as being in the process of construction, by the driving of two adjacent panels 2l)e each formed of a series of interlocking sheet piles IS. Each pile I6 comprisesa longitudinal at web lliel united at each edgewith a curved portion IGb, as shown in Fig. 2, and these curved portions are united with integrally formed hook members I6c and guard. members Ild. With this construction, there is provided at each edge of each pile a 1ongitudinal groove or recess I 6e which is adapted to be engaged by the hook member of the next adjacent, and reversely arranged, pile I6 when two piles are interlocked with each other.

In order that the piles I6 forming a panel 20e may be held in assembled relationship with respect to each other while the panel is being moved from the place of assembly to the place where the piles are to be driven, and to hold the panel in the desired shape, the various piles making up the panel are preferably secured to a channel-shaped bar 22 which is provided with a series of projecting wedge-bolts 22a adapted to engage apertures if which are formed in the webs of the piles, preferably adjacent the upper ends thereof. The bar 22 is adapted to seat against the webs of alternate sheet piles and when the wedge-bolts 22a, which are preferably welded to the bar, have been inserted through the apertures lf, the wedges or keys 22b are inserted through slots in the wedge-bolts, thus holding the sheet piles in place against the bar. The keys 22b are preferably carried by chains 22d which are attached to the upper ange of the bar 22 so that the keys are always in readiness for use. After a section or panel of interlocking sheet piling has been put in place, the keys 22b are removed and the bar 22 is taken away from the piles preliminary to driving the piles.

Assuming that a new section of the breakwater is about to be formed, a floating raft 23 is placed against the end wall 2l)b of the breakwater section which has previously been formed and the panels 20e which are to constitute one side wall of the next breakwater section are placed in position against the edge of the rait, which has a horizontal cross-section corresponding to the shape of the breakwater section to be formed. This raft is secured to the previously formed breakwater section and serves as a platform upon which the workmen may stand during the process of driving the piles which make up the panels 20e. When the panels 20e have been formed, they are placed in position along the edge of the raft with their lower edges resting on the bottom and one or more of the piles which are not secured to the bar 22 may be driven slightly into the bed of the river or harbor to assist in holding each panel in place. When these panels 2lie are thus put in place along the edge of the raft, they are spaced apart from each other and from the corner piles 2l distances which are each equal to the width of one sheet pile I6 and they are held in this spaced relation around the raft 50 by means of spacing devices or clamps 30 which are detachably secured to the lateral edges of adjacent sheet piles and which constitute the subject-matter of my said co-pending application y Serial No. 17,401, led April 20, 1935. After the 55 spacing devices 3, which may be formed of cast, forged or rolled steel, are put in place to space adjacent wall sections or panels from each other and to space the inner side panel from the adjacent corner pile 2l, the wall sections 20e con- 60 form to the curvature of the edge of the raft 23 and all of the piles IB occupy vertical positions in readiness for driving. Before these piles are driven, the detachable spacing devices 30 are removed and may be placed upon the raft. As the `65 spacing devices 30 are detached and removed from the spaced sheet piles which have been connected thereby, another sheet pile I6 is inserted in interlocking engagement with the spaced sheet piles which have previously been connected by those o spacing devices and one such sheet pile is inserted in the space between the edge of one panel and the adjacent corner pile 2l. This operation requires the elevation of the intermediate or connecting sheet piles I6, which are to occupy these 75 spaces, until their lower ends are capable of engaging the longitudinal grooves of the sheet piles which are to be connected by them. In Fig. l, these connecting sheet piles are shown by dotted lines and one or these sheet piles is shown as occupying an elevated position which permits its lower end to be passed into interlocking engagement with the panels I6 which constitute the edge piles of the two adjacent panels 20.

To facilitate the passing of a connecting pile into interlocking engagement with two adjacent spaced piles, a pair of guide members 40, constructed according to the present invention, are detachably mounted upon the upper ends of the previously positioned piles for guiding the new pile into interlocking engagement with the spaced piles. These guide members 40 are of the form shown particularly in Figs. 2, 3 and 4 and include right-hand and left-hand guide members for engaging the opposite edges of the same sheet pile. Each guide member comprises a horizontal bar lilla having a handle 401 projecting from the upper side thereof and having enlargements 40C at its ends from which project downwardly two pairs of spaced legs 60d. At one end, the bar 4)a is provided with a hook-shaped member 40e projecting from one of the enlargements 40C and constructed to conform to the shape and curvature of the guard members I Ed which are formed along the edges or' the sheet pile I6. The guide members 40 are put in place on the upper ends of the previously assembled and spaced piles I6 with the legs 46d straddling the portions I6a and 1Gb of the sheet piles, as shown in Fig. 2. Since the guide members 40 of each pair are constructed as right-hand and left-hand members, the guide fingers 40e on opposite guide members will be directed toward each other and they will be positioned directly above the guard members of the sheet piles and will form stops against which the hook members I6c of the piles to be driven may be placed, asV shown in Figs. 2 and 4. Then, upon moving the intervening sheet pile downwardly, the portions 40 of the guide members 40 serve as guides to direct the hook members I6c of the pile into engagement with the slots 16e of the spaced piles at the ends of the panels which have previously been positioned. When the connecting sheet pile has been driven downwardly from the position shown by dotted lines at the upper right-hand portion of Fig. 1 until it interlocks with the sheet piles at the edges of adjacent panels, it will form a permanent connection between those panels and all of the sheet piles of these panels'may then be driven into the bed of the river or harbor in which the breakwater or other structure is being formed.

Although one form of the invention has been shown and described by way of illustration, it will be understood that it may be constructed in various other embodiments coming within the scope of the appended claims.
