. SPECIFICATION formingspart of Letters Patent 'No. 760,859, dated May 24, .1904. r L

" a lican fiid'iei z'aleos. ;Seria1Nn.159,166. oam qe To all whom it may concern Be it, known that I, WILLIAM H. ELLIS, a citizen ofthe United States, residing at Boston, in the county, of Suffolk and State of Massachusetts, have invented new and useful Improvements in Pile-Driving Devices, of which the following is a specification.

This invention relates to improvements in pile-drivers, and has for its object to provide a pile-driving construction by means of which plles can be driven underwater as well as on land, the hammer efliciently guided to fall in alinement with the pile, and piles of any ,required length driven to any 'desiredfpoint above or below -the surface ofthe water.

In carrying out this invention Ifem'ploy with a pile-driver an adjustable hammer guide or chute,"which isjsubstituted for the .ordinaryfguideway between the uprights in a .pile d'river, up and down which the hammer slides. The adjustable hammer guide and chute is placed in any desirable position between said uprights of the pile-driver and as the pile is driven is lowered till, the vdesired position is attained for the depth at which the pile is to be driven., '1"

Referring to the accompanying drawings, in which similar figures Ofreference indicate like parts, Figure 1 is a view in elevation of a pile-driver, showing the invention. Fig. 2 is a view in elevation, showing the hammer guide or chute. Fig. 3 is a transverse section thereof, on the line on m, Fig. 2. Fig. tis a detail view showing the construction of the hammer guide or chute. Fig. 5 is a detail view showing a modification of the hammer guide or chute.

In carrying out my invention I employ a pile-driver 1 of the usual form of construction, but omitting the slideways or guides for the hammer from the uprights 2, In connection with this pile-driver 1 I provide a hammer guide or chute 3, of any suitable con struction, and adapted to be located in adjustable position between the uprights 2.. The hammer guide or vchute is preferably con-. structed as follows: It is made up in sections 4:, of any suitable length, fastened together. Each section as, here shown consists of four angle-irons 5, arranged at the corners of a square, and, held in this position byfbeing secured by rivets 6 to transverse flanged plates 7. The angle-irons 5 are braced by means of crossed metallic strips 8, secured together and to the angle-i rons .5 by rivets 6. The sections 4 are fastened together by bolts and nuts 9, en-,

gaging the flanges 10 of the plates 7. As many of the sections 4 are employed asare necessary to form a chute of the required length.

'In the foregoing construction the angle-irons '5 of the sections 4, abutting end to end, form the slideways or guides for the hammer. As here shown Ia hammer 11 of square shape is employed, which is adapted to slide be tweentheangle-irons5 and is provided with an'extendedportion 12,.whichis secured at its end to a wire rope 13, passing over a pulley 14 to ahoisting-drum. (Notshown.) The hammer guide.: or chute is not necessarily of a square shape, butmay' be formed'with two or more slideways for the hammer, according to the shape of the latter, to adapt. it to the chute. ..The lower end of the chute 3 is secured by cross-bands15, riveted to the angleirons v5. In order to readily introduce the hammer into'the chute 3, its uppercnd is preferably formed with an enlarged or flaringshaped top 16, constructedwith the inclined strips 17, fastened together at their upper ends by the riveted bands18.

In order to raise the chute 3 into position, it is provided at its upper end with suitable means for attaching it to a lifting mechanism and, as here shown, with a pair of angle-irons 19, one on each side of the chute 3 opposite to each other and riveted to the strips 17 and each having an ear 20, with an eye 21, riveted to the angle-iron 19. By means of this de- The pile-driver 1 being in position, the chute 3 is hoisted into position by means of the hoisting mechanism, hereinbefore described, between the uprights 2 and is secured in place by lashing or other well-known means. The pile to be driven is then raised by said hoisting mechanism and is lowered into the chute 3, the top of the pile being below the enlarged top of the chute. The pile is then driven by the hammer, and as the pile is driven down the chute 3 may be lowered until its lower end is adjacent to the bottom or substance into which the pile is driven, when the driving of the pile may be continued until the desired position is reached. p

While the chute 3 has been shown and de scribed as being separable from and independent of the uprights 2, it is not intended to limit the invention to such construction and arrangement, as the invention broadly contemplates a hammer guide and chute located and secured and adjustable in and removable from the uprights of a pile-driver in any suitable manner.

In order to obviate the hoisting of the pile when it is inserted in the chute 3, the latter may have one side hinged, so as to be opened %nd introduce the pile laterally, as shown in ig. 5. It will be seen that the chute constructed as herein set forth presents an open framework which is light, strong, durable, and economical.

By means of this device piles may be driven under water to a considerable deptl1, and the necessity of cutting ofi? the end of the pile, as in the old way, obviated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination with a pile-driver, of a hammer guide, or chute, independent of the pile-driver, and laterally, and vertically, ad-

in said uprights, as herein set forth.

3. A hammer guide, or chute for piledrivers, independent of and laterally, and vertically adjustably and removably connected with the uprights of the pile-driver, and consisting of an open framework, formed of guideways for the hammer, and braces, and connections, holding said guideways together, as herein set forth.

4:. A hammer guide, or chute for piledrivers, consisting of a number of sections bolted together, each section formed of guides for a hammer; cross-braces riveted to said guides, and flanged plates connecting the ends of said guides together, and bolted to the adjacent flanged plates, as herein set forth.

5. A hammer guide, or chute for piledrivers, consisting of an extended open framework, having guides for the hammer, and an enlarged upper end, as herein set forth.

6. A hammer guide, or chute for piledrivers, independent of and laterally, and vertically adj ustably and removably connected with the uprights of the pile-driver, and consisting of an extended open framework, with guides for the hammer, and means for attaching the chute to a hoisting mechanism, as herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
