` OLIVER CROSBY, OF ST. PAUL, MVINNESOTA.,

PILE-DRIVER.

specification of Letters Patent.

Patented Feb. 9, 1909.

` .hpplication `filed November 2, 1907. Serial No. 400,324.

To all 'whom it may concern:

Be it known that I, OLIVER CROSBY, of St. Paul, Ramsey county, Minnesota, have invented certain new and. useful improvements in Pile-Drivers, of which the following is a specification.

r.lhe object of my invention is to adapt a ditching machine for use as a pileV driver, the apparatus being capable of connection with a railroad ditching machine as illustrated, a log loader or a locomotive crane.

The invention consists'generallyin various constructions and combinations, all as hereinafter described and particularly pointed out in the claims'.l Y

ln the accompanying drawings, forming part of this specification, Figure lisa side view of a pile driving machine embodying my invention. Fig. 2 is a front view of the same. Fig. `3 is a sectional view on the line .a2- m of Fig. 2. Fig. 4 is a detail view illustrating the manner of pivoting the leads at the outer end of the boom.

In the drawing, 2 represents a car arranged to travel upon a track 8 and having a platform 4 on which track rails 5 are arranged to support a truck 6. A turn table 7 is mounted on the said -truck and supports a platform 8 whereonthe engine 9 is mounted. A; series of drums 10, 11 and 12 are geared to the said engine and a cable 13 passes from .the drum 10 to a pulley block 14 which has a connection 15 with the outer end of the boom 16 and through a pulley block connec- Ition 17 with a fixed point on the car. The innerend of the boom 16 is pivoted at 18 on the platform 8 and by the operation of the drum 10 the boom is raised .or lowered. frame 19 having a platform 20 is arranged beneath the boom and connected thereto by means of a bar 21. VThis platform has a pivot on the car frame that is concentric with the pivot of the, boom, whereby the platform and boom are adapted to swing vertically to obtain the desired angle of the lead beams.' This bar supports the scoop or shovel when the apparatus is used for ditching purposes. On the outer end of the boom a casting 22 is secured and leads 23 are connected at their upper ends by a cross beamy 24 which has a knuckle joint connection 25 with the casting 22 to permitthe lead beams to be swung back and forth in a vertical plane at an angle to the boom. VThe outer end of the frame 19 has a channel bar 26 provided with a central hole 27 and a series of other holes 28011 each side of the center.

A plate 29 connects the lead beams oppositefthe end-of the platform and said plate Y,

has a vertical slot 30 through which a bolt 31 passes into one of the holes in the channel beam 26. As indicated in full lines in Fig. 2' the lead beams are vertical and the bolt is arranged in the: center hole of the series. Upon loosening this bolt the lead beams may be swung to the dotted line position and securedin one of end of .the lead beams" swinging on the knuckle'join't described. Thus the apparatus can be operated at an angle to the vertical and piles can be driven thereby at an angle. The lead beams swinging through the desired arc obtain the necessary inclination of thev piling.

A pulley block 32 is provided on the top ofthe lead beams and a cable 33 passes from the drum 11 lover said pulley lto the pile driving weight 34 that is vertically slidable between guides 35 on the lead beams.

For the p'urpose of raising or pulling out a pile, l provide a cable 36 connected to the drum 12 and passing under a pulley 37 on the outer end of the frame 19 and over a pulley 38 at the outer end of the beam terminating in a hook 39.

This machine combines all the essential features of a railroad ditching machine and pile driver and can be easily adapted for either purpose. The pile driving connection is composed of but few parts of simple, durable construction and can loe utilized for the other holes, the upper driving piles either vertically or at an angle,

as may be desired.

l claim as my invention:

1. The combination, with a car, of a boom pivoted thereon, lead beams carried by said car, a platform supported on said boom and adapted to swing vertically therewith, means securing the outer portion of said platform to the lower portions of said lead beams, a pile driving weight arranged to slide vertically between said lead beams, operating drums mounted on said car and cables connecting said pile driving weight and said boom with said drums.

2. The combination, with a car, of a boom pivoted thereon, lead beams pivotally connected with the outer end of said boom, a platform supported beneath said boom and adapted to swing therewith, means adjustably connecting the lower portions of said lead beams with the forward edge of said platform, said connection allowing said lead beams to be adjusted at an angle to the vertical, a pile driving` weight arranged to slide vertically between said lead beams, and means for operating said beam and weight.

3. rThe combination, with a car, of a boom pivoted thereon, a casting secured on the outer end of said boom, lead beams having a cross bar connectingl them at their upper ends, said cross bar having a knuckle joint connection with said casting, means for connecting the lower ends of said lead beams and a pile-driving weight suspended between said beams.

t. In a machine of the class described, the combination, with a boom, of a casting` secured on the outer end thereof, lead beanie, a cross beam connecting said lead beams with one another and having a knuckle joint connection with said casting, a pulley block provided above said lead beam, a cable passing over said block, a pile-driving` weight attached to said cable between said beams, means for raising said weight and means for tilting said boom.

5. The combination, with a car, of a. boom pivoted thereon, lead beams carried by the outer end of said boom, a pile-drivingweight suspended between said beams, a platform arranged between said lead beams and said boom, a plate interposed between said lead beams and the forward edge of said platform, and a bolt adjustably mounted in the edge of said platform and on which bolt said plate is adapted to slide, for the purpose specified.

6. The combination, with a car, of a boom pivoted at one end thereon, a platform havl i l l l l l l l l l i l l i l l l i i l i l l i l l slidably and adjustably eonueeted ing a common pivot with said boom on said car, lead beams havin a knuekle `ioint eonnection withV the outer end of said boom, a piie-driringv weight suspended between .said ead bean a sliding eonneetimi interposed .ietween said lead beams and the forward edge of said platform, said connection beiney movable on the edge of said platform to allow said lead beams to be adjusted at an angie to the `vertical.

7. Ivihe combination, with a ear, of a boom pivoted thereon, lead beams pivoled on the outer end of said boom, a platform interposed between said lead beams and said boom, the forward edge of said platform foru'iing a supi'iort and ,duide for said lead beams and said platform having a eommon pivot on said ear with said boom whereby swung' in or out to said lead beams can be adjust them to the desired drivin;` anale and a pile-driving weight suspended between said lead beams.

S. The combination, with a ear, of a boom pivoted thereon, lead beams pivoted on said boom, a platform interposed between said lead beams and said boom, a plate having: a vertical slot interposed between said lead beams and the forward edgre of said plat form, said platform havingl a series of holes in its forward edge and a bolt resina through the slot in said plate and into said holes, and whereby the said lead beams are to Isaid platform, and a pile-driviire` weight suspended between said beams.

ln witness whereof, l hare hereunto set my hand this 15th da)vv of iletober '190i'.

OLVEH CROSBY.
