PILE DRIVING A DEUL ING MECHANISM.

'Application filed. March 27, 1922. Serial No. 547,168.

To all whom it may concern:

VAN a citizen of the United States, and a resident ofDover, county of Morris and State of New Jersey have invented certain new and useful Improvements in Pile Driv- The inventionmore particularly relates to concrete pile construction. In such constructions a pipe having a plug closing its lower end is driven by a pile driver and 1s then withdrawn leaving th plug and concrete is poured. into the hole.

This invention has for its object to provide apparatus by means of which concrete can be poured during'the withdrawal of the pipe. Another object of the invention is to provide a pile driving and pulling mechanism so constructed and arranged that the change from driving topulling and vice versa can be made without disconnecting or reversing change in the valve mechanism.

Another object of the invention is to provide a device of the character described that can easily and quickly be changed from a driving to a pulling rig. 7

Further objects of the invention will appear from the following description taken in connection with the drawings which form a part ofthis application and inwhich- Fig. 1 is an elevation of a driving and pulling rig constructed in accordance with my invention and showing the parts in driving position.

Fig. -2 is an elevation of the construction shown in Fig. 1 but showing the parts} in position for pullingor withdrawing a pile.

Fig. 3 is an elevational view taken at right angles to Fig. 2.

Fig. 4 is a longitudinal sectional elevation of the construction shown in Fig. 1.

Fig. 5 is a longitudinal sectional elevation of the construction shown in Fig. 2, and

Fig. 6 is a longitudinal view of the structure shown in Fig. 3.

Fig. 7 is a transverse sectional elevation taken upon line 77 of Fig. 4.

The invention may be briefly described as comprising a vibratory hammer, means for suspending the hammer and a pair of anvils supported at the opposite ends of the hammer .Be it known that. I, THOMAS E. STURTE-V a pile;

are slidably supported between the bars 12. v

The pile driving and pulling mechanism comprises the cylinderblock'13 mounted on the straps 10 and formed by the blocks 12 and enclosing a piston or hammer 14:. 15 is valve mechanism for controlling the admission and exhaust of the motive fluid.

An anvil 16 is mounted on trunnions 17 at the upper ends of the slidable links 13 and opposite one end of the piston lfand an anvil 18 is mounted on trunnions 19 at the other end of the piston and in the'opposite ends ofthe links 13. The

anvils

16 and 18 are slidablymounted between the upper and lower ends respectively of the blocks 12.

The lower ends of the links 13 are connected by a pair of links 20 to trunnions 21 formed on a clamping 'collar22 which is means connecting the anvils to The parts are'so constructed and arranged that the hammer" and anvils are movable in such a waythat the secured by wedge 23 to the pile or pipe 24. j

pivoted are provided with longitudinal slots 26 which receive the trunnions 21 and the function of these slots will be clear from the description of the operation of thedevice. In Fig. 1 the rig is shown with the parts driving position and from this showing it will be seen that the Vibration of the hammer or piston 14' will cause it to engage the anvil 18 which is positioned on top of the collar 25 carried by. the upper end of the pipe and extends into the cylinder 13 a'sufl'icient distance to be engaged by the piston or hammer 14. The pipe 'will therefore be driven as the hammer vibrates.

When the device is to be used as a lifting rig the straps or suspension means 10 are drawn upwardly to the position shown in whereas in Fig. '1

Figs, 2 and 3 in which position or piston 14: will engage the upper anvil 16 and because of its movement relative to the lower anvil the hammer will not engage the lowerv anvil. It will also be noted that in this position of the parts the trunnions 21 are disposed at thelower ends of the slots 26 with the anvil 18 lowered to engage the top of the pipe or collar the trunnions are disposed adjacent the upper ends; of the slots, a slight clearance being provided inthe slots beyond the trunnions,

In order to more clearly indicate the limits ofmovementof the piston the upper and I links 13 and subsequently-causes amovement lower limits of its movements have been indicated by dot and dash ,linesin Figs. 1 and 2.

It should be noted that in changing from pulling to driving the lowering of the suspension means will first etlect a relative movement of the cylinder and piston in the of thalinks thereby positioning the lower anvil 18 on the upper end of the pipe collar 25.

From the foregoing description it will be seen that by simple, longitudinal movement of thestraps or suspension means 10 the rig may be changed from a driving to a lifting device or vice versa; and that it is not necessary to disconnect, invert or otherwise rearrange the elements.

Although one specific embodiment of the invention has beenpa-rticularly shown and described, it will be understood that the invention is capable of modification and that changes inthe construction and arrangement of the various cooperating partsinay be made without departing from the spirit or scope of the invention as expressed in thefollowing claims.

;\Vhat I claim is 1. Ina device for driving and pulling piles, a reciprocatory pile hammer, a pair of anvil blocks disposed at the opposite ends of the hammer and means for relatively slidably adjusting the blocks and hammer to bring either block into the range; of the hammer.

2. In piles, a pair. of relatively slidable sections, one section carrying a vibratory hammer and the other section'carrying a pair of anvils selectively engageable by said hammer and means for connecting the anvil carrying section to a pile.

the hammer a device for. driving or pulling .3. In a device for driving orpulling piles, a pair of relatively slidable sections, .one section carrying a vibratory hammer and the other section carrying a pair of anvils disposed at the opposite end-s of and selectively engageable loysaid hammer and means for connecting the anvil carrying'section to a pile.

a. In a device for driving or pulling piles, suspension means,

a vibratory hammer carried thereby, a pair of anvils disposed at opposite ends of the hammer, and means for connecting the anvilsto a pile, said hammer being slidable with reference to the anvils whereby either anvil may be engaged there by. I V V j I 5. In a device fortdriving or pulling piles, suspension means, a vibratory hammer caried thereby, a pair 0f anvils disposed at opposite ends of the hammer, and straps for connecting the anvils' toi .:a1pi'le,f mer being slidable with reference, to the anvils whereby either. anvil may be-engaged thereby. I I Y 6. In a device for driving or pulling piles, suspension means, a vibratory hammer carried thereby, a pair of anvils disposed at opposite ends of the hammer, and straps slidably mounted in sa idsuspension means for connecting the anvils to a pile, said hammer being slidable with reference to the anvils whereby either anvil may be engaged thereby. 1, I

7. In a device. for driving andpulling piles, a cylinder, a piston therein, an anvil at each end of the piston, means for connecting said a-nvils :to a pile, said connecting means being slidable relative to the cylinder and piston to bring either anvil into the cylinder and in a position tobe engaged by the piston' 8. In a device for driving and pulling means, a vibratory hammer piles, suspension links slidable with respect carried thereby,

said ha-mto said suspension means,a pair of anvils 7 downward movement will bring the lower anvil in contact with the pile. a In witness whereof, I have hereunto set my hand this 24 dayof March, 1922.
