SPECIFICATION forming part of Letters Patent No. 757,960, dated April 19, 1904. Application filed April 3, 1903. Serial No. 150,986. (No model.)

To all whom, it may concern:

Be it known that I, HIRAM W. PHILLIPS, 0 Quincy, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Pile-Driving Apparatus, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of piledrivers that are used for driving piles under water, and especially in locations in which the water is comparatively very deep and the heads of the piles are so deeply submerged as to be beyond the capacity of the ordinary pile-driver.

The apparatus is necessarily mounted upon a scow, float-stage, or other device for holding it steady while working; and it consists in combining with a suitable supporting-frame a telescopic adjustable tube comprising a fixed member and one or more adjustable members constructed to serve as a guide for the piles and devices for controlling the said tube.

It also consists in several minor arrangements, the exact nature of which will be fully set forth.

The object is to construct a reliable apparatus by which piles may be accurately placed and readily driven in deep water. This object I attain by the mechanism shown in the accompanying drawings, in which Figure 1 shows in side elevation a scow having a complete pile-driving apparatus including my improvements. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical section showing the arrangement of the telescopic tube. Fig. 4c is a horizontal section of the said tube, taken on line 4 4 of Fig 3. Figs. 5 and 6 show details in elevation and vertical section.

I have shown my apparatus as erected on a scow A, which has hoisting-engine B B B and a derrick C C C All of these are of ordinary construction and need not be described in detail.

The pile-driving apparatus consists of a framework, of which D D are base-beams firmly bolted to the scow and braced by beams D D and also stayed by a cross-tie D The standards E E, which serve as guides or ways for the supplemental or auxiliary guide for the immediate control of the hammer, are firmly connected to the beams D D and have a cross cap-piece E and cross-ties E E The braces F F serve to hold the standards E E and, with the cross-bar F, to give the whole frame the required strength and firmness.

A novel feature of this apparatus is the pile guiding and holding device, which consists of a telescopic tube H K. This tube consists of an outer tube H, which is detachably connected to the scow by the base of the framework and by guy-ropes G G G which are attached to the outer tube H at H H H H H H H are four guide-rollers located inside of the tube H and near the lower end. (See Figs. 3 and 4.) The inner tube K has also four guide-rollers K, two of which are shown in Fig. 3. This inner tube K slides freely up and down in the outer tube H and is guided by the rollers H and K. A hoisting-rope K Figs. 1 and 3, is attached to the lower end of the inner tube K at K and is operated by the drum B of the hoisting-em gine. A series of openings K K are made in the inner tube K to admit of the free escape of the water as the hammer operates. This tube is also weighted, so as to sink in water. The telescopic tube H K may when not in use be drawn up by the derrick and laid upon the deck of the scow, connection being made by the hook C and the eyebolt at Another novelty of my apparatus consists 8 5 in a supplemental guiding-frame that is construeted for the immediate control of the hammer W and consists of a frame L L L L L L (SeeFigs. 2, 5, and 6.) This frame slides between the standards or ways E E, its downward motion being limited by the stops L L*, Fig. 2, permanently attached to the standards E E. The upper end of the hammer W is made tapering, as shown in Fig. 6, so as to engage with the cleats L L at the top of the guiding frame, and thus prevents it from passing beyond the upper edge of the supplemental frame and also to cause the hammer in its upward passage to take the frame with it. The hammer W is operated by the fall W,

and blocked. A pile of such length as is desired to be driven is put' into the inner tube. The hammer, with its guiding-frame, is caused to descend. When the lower end of the hammer enters the upper end of the inner tube, the guiding-frame is arrested in its descent by stops fastened to the standards. The hammer leaves the frame and goes down inside the inner tube, pushing the pile ahead. When the hammer is half way or more througlr the tube, it is stopped, and the tube is lowered until its lower end touches bottom.

The hammer is then allowed to drop. The hammer fall being marked and the distance between the face of the hammer and mark on the fall being known, with proper care piles may bedriven sufficiently accurate so as to eliminate the necessity of sawing them off after being driven. Where the water is sufliciently clear, a straight-edge having a spiritlevel fastened to it may be used as a guide, one end of the straight-edge resting on a pile which has been driven to the desired grade, the other end of the straight-edge placed beside the lower end of the inner tube at an elevation known to be correct, as shown by the spirit-level. The pile can be seen through the water-escape openings, and when the head of the pile is down to the required grade a signal is given and further driving is discontinued. The work is usually performed in connection with a diver.

I claim 1. In a pile-driving apparatus: a hammer and means for operating it; a supplemental guid- The hammer and its guid-' ing-frame, open at its lower end to allow of the passage of the hammer, constructed to slide between and to be guided by the main standards, and having top cleats adapted to engage with the upper end of said hammer whereby the said hammer in its ascent takes the said guiding-frame with it; and stops attached to the main standards, constructed to limit the downward passage of the said guiding-frame; substantially as and for the purpose set forth.

2. In a pile-driving apparatus: a hammer, and means for operating and guiding the same; a telescopic tube, adapted to receive and direct the piles, extending from the base of the pile-driver downwardly, said tube' comprising a main tube and one or more extensions constructed to extend to the required length, and

means for operating said tubes; substantially as and for the purpose set forth.

3. In a pile-driving apparatus: a hammer and means for operating it; a supplemental guiding-frame, open at its lower end to allow of the passage of the hammer, constructed to slide between and to be guided by the main standards, and having top cleats adapted to engage with the upper end of said hammer whereby the said hammer in its ascent takes the said guiding-frame with it; stops attached to the main standards, constructed to limit the downward passage of the said guidingframe; and a telescopic tube, adapted to receive and direct the piles, extending from the base of the pile-driver downwardly, said tube comprising a main tube and one or more extensions constructed to extend to the required length, and means for operating said tubes; substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 30th day of March,
