WILLIAM H. WABRINGTON, OF CHICAGO, ILLINOIS.

CAP FOR SHEET-FILING.

T all whom it may concern:

Be it known that I, WVILLIAM H. VAR- RINGTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Caps for 7 to which this invention pertains it is sometimes necessary that some of the members of the piling shall be driven in alinement with one another, and that other members thereof shall be driven at angles to the alined members, in other words, some of the sheet piles may be driven in alinement or in parallelism with the pile-driver sills, and it is necessary to drive other of the sheet piles in angular relation thereto, which operation has heretofore required the shifting or changing of the position of the pile driving machine, in order that the cap for the sheet pile being driven could be properly placed on the upper end thereof. Sometimes the sheet piling has to be driven in a line at varying angles to the pile driver leaders, the angle varying with each sheet pile.

The principal object of the invention is to furnish a suitable cap with provision for adjustment to drive sheet piling in a line not in a line with the horizontal axis of the pile driver sills, and for driving the sheet piling in lines at varying angles to the pile driver leaders without changing the angle of the position of the pile driving machine.

Other objects and advantages of the invention will be disclosed in the subj oined description and explanation.

In order to enable others skilled in the art to which my invention pertains, to make and use the same, I will'now proceed to describe it referring to the accompanying drawings, in which Figure 1, is a view in side elevation of a cap for sheet piling embodying one form of Specification of Letters Patent.

Application filed February '7, 1910.

Patented June *7, 1910. Serial No. 542,561.

the invention and showing the parts connected together and in position to receive the blow from the hammer; Fig. 2, is a bottom plan view of the cap or driving-hood; Fig. 3, is a similar view showing the follower in place on the cap or hood; Fig. 4, is a top plan view of the follower removed from the cap; Fig. 5, is a plan sectional View taken on line 55 of Fig. 6, showing a modification in the means for interlocking the follower and cap; Fig. 6, is a fragmental view in elevation of the modified form of the cap; Fig. 7 is a plan view of another modified form of the follower; and Fig. 8, is a fragmental view in side elevation of another modification in the construction of the pile cap.

Like numerals of reference, refer to corresponding parts throughout the different views of the drawing.

The reference numeral 10, designates a pile cap or driving-hood which may be made of any suitable size and form, but preferably of the shape shown in the drawing, and provided with oppositely disposed side recesses 11, for the reception of and operation upon the leaders (not shown) of the pile driving machine. The cap 10, may be provided in its upper portion with a block 12, to receive the blow from the hammer of the pile driving machine, and may be of the ordinary or any preferred construction. Extended from the central portion of the lower surface of the cap 10, is a pint-1e 13, of any desired length, which is adapted to fit in a chamber or cavity 14, formed in the central portion of the upper surface of the follower 15, which is provided in its lower surface with one or more grooves 16, preferably of the form of the sheet-pile to be driven, in cross-section. In the present instance, the follower 15, is shown as having two grooves 16, intersecting one another and arranged diametrically with respect to the follower and in its lower surface, but it will be understood that one 01' more grooves may be employed, and that it or they may be of any desired shape or form. The lower surface of the cap 10, is provided with a series of radially and downwardly extended projections 17, to fit in radially disposed openings or recesses 18, formed in the upper surface of the follower 15, around the cavity 14, therein for the pintle 13, of the cap. As shown, the cap 10, is provided near each of the side recesses 11,

with an opening 19, extended therethrough for the reception of cords or cables 20, used to support it, and that it also has an opening 21, extended through its central portion for the reception of an endless cable or rope 22, which is employed to connect the cap 10, and the follower 15, together, yet in such a manner as to permit them to be adjusted with respect to one another. The follower 15, is provided with a series of radially disposed openings 28, which are also for the reception of a portion of the cable, or rope 22, and said openings are extended entirely through the follower, and preferably just below the cavity therein for the pintle of the cap.

In Figs. 5, and 6, of the drawings, is shown a modification in the construction of the means for interlocking the pintle of the cap and the follower which consists of a follower 15, of the same construction as just above described, except that the cavity 14, therein, for the reception of the pintle is provided with vertical corrugations in its walls to engage similar corrugations 24, on the walls of the pintle 13, which construction it will be understood differs only from that shown in Figs. 1, to 4, inclusive of the drawing and above described, in that the first described construction, the walls of the pintle 13, and cavity 14, are circular, smooth, and without interlocking means, while in the modified construction the walls of the said parts are provided with vertical grooves or corrugations to prevent the cap turning on the pintle until desired.

In Figs. 7, and 8, of the drawing. are shown other modifications in the construction of the pintle of the cap, as well as in the follower, which consists in providing a follower 15 with a cavity 14 the upper portion of which is polygonal in form, while its lower portion is circular as shown at 25, to receive the cylindrical portion 26, of the modified form of the pintle 13*, the upper portion of which is polygonal in form to correspond with the similarly shaped cavity 14 in this modified form of the follower. It will be understood that other means for locking the follower against its rotary movement on the cap besides those shown and described, may be employed, without departing from the principles and spirit of the invention.

From the foregoing and by reference to the drawing, it will be clearly understood and readily seen that the interlocking devices for preventing rotary movement may be dispensed with, and in such an event the rope or cable 22, which coimects the cap and follower together should be slack enough to allow free swiveling of the follower. Where an interlocking device is employed, the said rope should have enough slack to allow the follower to drop clear of the locking device so as to permit free swiveling, to the end that after the sheet piling has been swung into place, the follower can be lowered on to it, so that one of its grooves 16, will receive the upper end of the pile, after which the pile cap 10, may be lowered to rest on the follower ready for driving, when it is apparent that the sheet pile will be held by the follower, which is held by the pile cap or hood, which in turn, is held in place by the leaders of the pile driving machine.

Having thus fully described my invention what I claim as new and desire to secure by Letters-Patent is 1. A cap for sheet-piling, consisting of a pile-cap and a follower having in its lower surface one or more grooves and adjustably connected to said cap.

2. A cap for sheet-piling, consisting of a pile-cap and a follower adjustably connected together and having co-acting interlocking means.
