SUBA-QUEOUS PILE-HAMMER.

Application filed April 117, 1917. Serial No. 162,897

.7'0 all whomz't may Concern:

Be it known that I, TiioMs E. STURTE- vAxT, a citizen of the United States7 and a. resident of Dover, Morris county, and `State of New Jersey, have invented certain new y 1id useful Improvements in Siibaqueoiis Pile-Hammers, of which the following' is a specification, reference being hadv to the 4accor'npanying drawings, forming a part.

thereof.

My invention relates to improvements in pile. hammers and more particularly to a structure which is capable of being operated under. water. Its object is to provide a simple, rugged and eflicient apparatus for driving vpiles and the like and to so construct the parts. that submei'ging it under water will not affect its effectiveness.

In order that my invention may be. thoroughly understood I will now proceed to describe the saine in the following specification, and then point out vthe novel features thereof in appeiided claims.

Referring to the drawings: v

Figure l is a sectional side elevation of a pile hammer 'made according to and ernbodying my invention, the section being taken through the center of the apparatus.

Fig. 2 isa sectional .front elevation of the saine structure, the section being taken von the line 22 of Fig. 1, looking in the direction of the arrows.

Fig. 3 is an elevation of a portion of the valve rod and Figs.- 4, 5 and 6v are sectional plan views of the rod, the sections being taken respec. tively onl the-lines fit-4, ,5e-5 and G-tiof Fig. A. l

Figs/7, S and 9 are sectional plan views of the apparatus shown` in the lpreceding figures. the sections being taken respectively onthe Fig. 1 0 is a sectional side elevation of a simple apparatus which valso embodies this.

lFig. 11 is a sectional' plan view of, the. structure shown in Fig. 10.

There is l1owever, a short rib 56 project` ing integrallyfrom the hammer block into the-groove 55 and into a groove 57 in 4the valverod, the ends of which are inclined 'a suitable source of supply1 may be led turn the valve and put it in position to'connect the upper end of the cylinder-llwith in opposite directions.' By thisarrange `ment an oscillatory rotation is impartedtoY the valve rod by the hammer block dur-I ing its movement which causes lthe ports previously described to be opened and closed tofactua'te the piston.` 4

v 37 is a port with which an'air tube 38 may be conncctedrthrough which airl from through a regulating valve 39. It is to be understood that suitable tubes may beconnected similarly with the supplyiand exhaust ports 42 and 43, f

The operationofthis device is asl follows :"-the apparatus is supported by a cable or chain'run under sheave 172'- It-is.

lowered onto the object to bevdriven with the lower end 30 of the anvil block'27 resting upon the object 'so that substantially the whole weight of the apparatus is upon the pile or other object to be driven. Now when motivelfiuid under p ressu're'yis admitted through port 42 it will be led alternately through the rotary valve to the opposite ends of the cylinder 11. If it is led first .to the lower end thereof, the piston 12' will be "raised andA with it the hammer block Q2. During this part of the operation the upper end of 'the cylinder* will be connected through thevalve with exhaust.

This movement ofthe hammer block will the airi supply and the lower end thereof with exhaust.` This will result in the downward movement of the hammer block which will deliver a heavy blow on the anvil block 27 at the end of its stroke, and as thelatteris resting on a pile or something else to be Vdrven, the blow will be transmitted', tothe latterobject; It is` evident .that this operation will be repeated rapidly and continuV ously as longV as motive iluidsuch as cornpressed air,-'is supplied.

lThe .construction of the device is such 30* thatfiti'swater-tight so that when it is submerged its operation will not be retarded. thereby- The .result is that' a pile for example maybe Vdriven down underthe water level ,as :far as desired. -l

The air supplyto the hammer block barrel through'tubeBS is provided So that the packing rings 28.1'1eed not be Adepended' upon to kee thewater out of the apparatus:

Air is supp ied through the regulating valve 39 at a desired pressure sufiicientto counteract the, pressure of the water due to the depth of submersion-- ofthe device'. The

slots or grooves 23 provide-paths forffree of the hammer block. The devicevshow-n in Figs.. 1 '0, and 11 `i`s a `circulation of the air between lopposite`ends.

GO- is 'a prsmatic body having a central borer'l in whichgis a hammer block 62. 63 is theup'perhead ofy this, device and '64; its lower head. Below this is a cupped end member 65.

In the lowerhead 64 `is ali anvil block'SO,

provided with packing' rings8l. Its upper end 82 is of smaller diameter than is the part which carries the packing rings and projects into a restricted opening in the head 6 4. The lower end of 'the hammer block is also restricted in diameter as at 83 to allow it to pass freely into .the l'smaller bore 'of head 64. The lower end'' ofthe anvil block is also of smaller diameter than'that of the central part of this membenand an annular' collar 85 of the cupped member fits around shown in thepreceding` fi ires, so far as the this lower end of the vanvil 4block and retains ros driving andl themeans orkee lng water' out of the hammer block. cham erjisi-con-r cerned.
