PILE DRIVER AND FULLER.
Specification of Letters Patent.
Application filed August 5. 1915. Serial No. 43,800.
To all whom it may concern:
Be it known that I, CHARLES S. Bonne- MAN, a citizen of the United States, residing at Buft'alo,in the county of Erie and State of New York, have invented new and useful Improvements in Pile Drivers and Pullers, of which the following is a specification.
This invention relates to pile drivers and consists in an essentially new structure whereby the blow maybe applied tothe pile below the end thereof and as near the point of penetration as may be desired.
I-Ieretofore, so far as I know, all piledrivers and similar mechanisms operate to strike the pile at its upper endand can only so operate. And with such arrangement, considerable space or head room is necessary to accommodate the guides and other supports for the strikingpart and to permit a sufficient extent; of movement ofsaid striking-part above the pile end. Also all piles are more or less flexible; there is therefore a dissipation of the. force of the blows owing to the bending of the pile, and sometimes the pile itself is distorted or broken.
To overcome these disadvantages and as a radical departure from these old mechanisms, I have devised a pile-driver with which head-room is not necessary, but the pile is gripped at any convenient point below the top, and the force of the blow delivered below the point of grip and near the point of penetration. Thus the force is applied down on the pile, and the dissipation of the force due to the flexibility of the pile becomes negligible. Furthermore the fact that all the mechanism of the piledriver is arranged entirely below the upper end of the pile permits the driving in many locations-impossible with the ordinary piledriver and often permits the use of longer piles desirable for the particular installation. In some cases a longer pile is neces sary for the safety and stability of the structure. I
My invention will be understood by reference to the accompanying drawing wherein the reference numerals of this description are applied to the same parts in the difi'erent views. Figure 1 is an elevationof my improved pile-driver with parts broken away and parts shown in section. Fig. 2 is a similar view, slightly modified, showing the piles.
thedevice in inverted position for pulling Fig. 3 is a side elevation of Fig. 2. Fig.4 is a top plan of Fig. 2.
My improved driving tool or hammer as here shown has supporting side-plates or yoke-plates. 11 clamped together by clamping-bars 2-2, which are secured to the plates by the bolts 3-3. A supporting frame is Patented July 22, 1919.
thus formed with the side-plates separated to leave an open space through the frame for plates or jaws 4c4: on the toggle-links 55 pivotally supported on the pins 6-6 carried by the plates 1, and spanning the space between them, as shown. This gripping mechanism operates very firmly to grip the pile and to prevent movement of the frame relative to the pile section in one direction, while permitting the frame to be moved longitu'dinally in the other direction for readjustment of its position as hereinafter referred to. I do not propose to limit myself to this grip for that is merely a detail and any suitable form of grip or means for engaging the'pile, may be used.
To the supporting frame I fit the hammers 8-S in any suitable way, preferably in the manner here shown, wherein the hammers are each complete self-contained hammer-units (of any desirable form) for instance composed of the striking part 8 operating within the cylinder casing, or block, 9, and provided with a piston-head 10 fitting the cylindrical chamber 11 formed within the cylinder casing. The elastic fluid, usually steam or air, for operating the hammer is controlled by a suitable valve 12 of usual form for introducing the fluid through the ports 13 and 14: respectively above and below the piston head.
mer units at theirupper ends, and at their bottom ends they are supported upon the anvils, or dolly-plates 17, which rest upon form of frame or of hammer here shown, for e the details of the frame may be varied and any suitable form of hammer unit used therewith. A single hammer only, may be used if desired, the arrangement shown permitting the hammer to be easily removed as a complete unit for independent use. On the other hand the hammers may be made a permanent part of the puller, so as to de crease the size and weight thereof, if desired.
The arrangement shown, whereby the pile-section may freely pass between the hammers and the gripping jaws, permits the adjustment of the pile-driver with reference to the pile at any desirable elevation so that the impact of the striking part may be communicated to the pile at a point close to the point of penetration, and, as the pile is driven, obviously the hammer may be raised step by step, as required for obtaining a renewed grip upon the pile.
Thus, as above suggested, my new form of pile-driver, operating .in a new manner and on a new principle, makes possible the driving of piling in locations where before impossible on account of lack of head-room, for instance under bridges, in basements of old buildings, as for reinforcing foundations, etc. With my pile-driver, piles extending throughout the entire head-room can be driven, and this in places where longer sections are important as for protecting bridges etc. Thus in some locations, without my peculiar pile-driver, no piling installations at all would be possible for piles of sufficient length to be of any practical value could not be used.
Often the piling is to be driven under water, or down into the ground, where a follower is necessary, and with my piledriver the follower is steadied and stifiened till the section is driven home. Often there will be locations where, with the ordinary type of pile driver, a follower could not be used, or could not be used. of desirable length.
As a matter of course, my pile-driver may be used in the ordinary manner, and in that case the keys 18 are removed, the dolly plates 17 withdrawn, and the pile-driver arranged so that the striking part strikes directly on the upper end of the pile. lVhen so used it has the advantage of operating on two adjacent piles at once, or alternately; a driving cap of usual structure is preferably set on the ends of the piles, one or more being driven. Such caps may have a single and the pile section.
round socket to fit a bearing pile and grooves for two sheet piles. The two adjacent piling sections may be driven by alternate or simultaneous blows.
Another important feature of my improved mechanism is that it can be used in an inverted position and in conjunction with pulling tackle, or any pulling appliance, to impart upwardly directed impulses to the pile so as to assist the loosening and withdrawal of the pile, by applying rapid jerks and continuous vibration thereto, at the same time that the pulling strain is being exerted thereon.
lVhen so used for pulling, the driverpuller is inverted as shown in Fig. 2,- and in this position also may bearranged at any desired elevation with reference to the pile, preferably close to the ground, and the pulling power is applied from the usual hoisting engine to the (then) upper end of the drive1"-p1.1ller, and through the same imparted to the piles. To that end the sideplates 11 are provided on their then upper ends with straps 20-20 or other means for supporting the driver-puller on the pulling tackle or lever, so that the driver-puller provides the connection between the tackle As will be readily understood, my improved driver-puller may be raised to an height required for pulling the entire length of pile or it may be kept at a low elevation at all times by releasing the grips when the pile has been pulled a short distance and then sliding down along the pile for a second engagement of the grips to pull from a lower elevation and so on down step by step. Often the blows are needed only initially to loosen and start the pile.
While my invention is particularly useful 7 with metal sheet piling, yet it may be used with any form of piling, and much modi fled, in form without departing from the spirit of my invention. As here shown the gripping jaws are designed particularly for engaging the web portions of steel sheet piling but they may conveniently be modified to correspond to the type of pile desired to be driven, for instance round piles, or hear ing piles of other forms, or piles made of wood, reinforced concrete or other mate I form. By reason of my invention, a much lower and smaller frame or equipment to handle the pile driver can be used than with ably arranged on the frame, a pair of jaws for gripping the sides'of the pile adjacent one end of the frame and toggle supports for the jaws adapted to insure firm engagement 1 of the aws with the pile, when force is applied to the device in one direction, but to permit the jaws to loosen and the device to move along the pile when the force is applied in the opposite direction.
