5 Claims.

This invention is directed to an improvement in pile driving attachments to be secured to the base of a locomotive crane for driving piles or similar work at any desired location.

Locomotive cranes are usually track-traveling and carry a boom by which supplies may be lifted from a flat car in rear of the crane and carried to a position desired for use. The improved pile driving attachment is designed to be xedly secured to the crane proper and to operate in advance of the same, the arrangement of the pile driving attachment being such as to avoid any interference with the usual handling or movement of the crane boom and, in fact, is arranged so as to permit the crane boom to pick up and deliver piles to be -dr-iven by the pile driver attachm'ent.

'The primary object of the present invention is the provision of 'a pile driving attachment in Y which the guides for the ram or hammer may be selectively moved at different vertical or horizontal angles in order that the driving -action may belother than .directly vertical to accommodate different conditions of driving.

A further object of the invention is the provision 'of a--steel tower as a part of the pile driving attachment, which tower serves to suppo-rt the hammer guides and to provide for the adjustment `of the guides at `different angles, the tower also providing at convenient heights independent pl-atforms for the convenience of workmen.

'The invention -is illustrated in the accompanying drawings, which:

Figure 8 is a frontelevation of the attachment.

The attachment is shown in connection with a locomotive crane car indicated at l0 and adapted `for travel -on .tracks v5l and Vconnected to one or (C1. (il-74) more dat cars 5c for supplies. Secured to and beneath the metallic -beams l5 of the locomotive crane car are I-beams 45 forming part of the attachment. These beams -45 extend 4in advance of the .ends of the beams l5 and are secured thereto by bolts 49 to the flanges l'of the beams and tie-bolts 48 which 'extend through plates above and below the beams I 5 and 45, 'as indicated more particularly in Figure 3.

The extended portions of the beams 45 of the 10- attachment, suitably braced by cross-pieces 41, carry a platform ed. A skeleton tower of metallic uprights secured at the bottom to angle pieces 46 bolted to the beams 45 is erected on the platform 44 for an appropriate height. Itis to be par- 15 ticularly noted that this beam is set at a-n angle,

so that its upper end is substantially in line with the forward ends of the beams '45 in order to provide a proper support for the upper yends of lthe hammer guides.

The upper end of the tower is provided with a hollow head 3l' in the walls of which is xed a heavy duty bolt or shaft -34 on the forward end of which is swingingly supported a plate 33 hav ing hinged knuckles 32 and carrying a pivot pin 25 35 on the ends of which are supported other hinged knuckles 3l secured to a hollow casting '29 which extends materially above `the hollow head 3l for a purpose which will later appear. yThe casting 2d is open on its Aforward e'nd and se- 3@ cured to the forward edges of the side walls of Ithis casting are hammer guides made up of U-s'haped bars i8 in which is xed a wooden insert I9, the relatively inner surface of which extends inwardly beyond the edges of the bars I8.

The bars iS and wooden strips I9, which constitute the guides for the hammer, extend vertically, terminating at their lower ends below the ybeaI'r-is i5 in order to permit an effective stroke of the hammer below said beams for driving piles and 40 the like to a greater depth or lower level than ordinarily permissible in devices of ythis type. At appropriate points throughout their lengths, :the guides are held in rigid spaced relation Iby tie members constituting holding members :and made 45 up of metal bars 2i of substantially semi-circular shape in plan, to the inner surfaces of the ends `of which the guides are rigidly secured, as for 4eX- ample by bolts Z, as indicated in Figure 5.

The forward ends of the beams support a 50 transverse bar 23 which extends in both directions beyond the beams Q5 and the upper surface of which is` curved from a center at the pivot 34. The upper surface of the bar 23 is provided with a .plate 24, or, if desired, such plate may consti- 551 tute the upper surface of the bar 23. This plate is formed with a series of openings 25 extending longitudinally thereof, and the plate or the upper surface of the bar 23, as the case may be, has a curved formation, the curvature of which is struck from the pivot 34.

The extreme lower support for the hammer guides is in the form of a plate 22 designed to overlie and rest upon the plate 24. The forward portion of the plate is formed on a curvature corresponding to that of the intermediate guide braces 2|, and the guides I 8 and I9 are rigidly secured to the forward edges of the plate 22. The plate 22, which overlies the plate 24, is formed with openings to receive pins 26 which may be removed at will in order that the plate 22 may be moved to any series of holes longitudinally of the plate 24, as will be plain from Figure 2.

As the hammer guides are rigidly supported at the upper ends by the casting 29, at the lower end by the plate 22 and intermediate the ends by any appropriate number of braces 2l, it is apparent that the guides will move as a unit and that by reason of this rigid support being swung on the bolt 34 and the lower rigid support capable of being arranged in any position longitudinally of the plate 24, it is apparent that the guides may be given any vertical angle within the limits of the plate 24 or held in a vertical position at will.

Furthermore, it will be understood that as the casting 29 is supported for swinging on the hinge bolt 35 in a direction at right angles to its movement on the bolt 34, the lower ends of the guides may be moved outwardly from the beams 45 to various angles in such adjustment with corresponding inclination for the movement of the hammer.

The hammer is operated by means of a drum 40 mounted upon the platform 44 operated by an engine 42 from steam conveyed through a pipe 43 from the usual boiler I4 on the crane car. Of course, this pipe will extend through the center pin of the crane car and be provided with a universal connection to permit turning of the crane car Without interfering with the steam supply to the engine 42. Obviously, of course, where electric power is available, the engine 42 may be in the form of a motor.

A cable 39 is wound on the drum 40 carried over a guide 38 at the upper end of the casting 29 and connected to the hammer I 1, the ends of which, of course, are recessed to cooperate with the guides. It will be noted that the recessed ends of the Weight contact more particularly with the Wooden surfaces of the wood strips I9. This avoids the usual noise and provides a more effective operation. The drum 40 is provided with auxiliary drums 4| over which cables (not shown) are led over guide pulleys 2'I on the end of the plate 24 and connected to the plate 22 to facilitate the movement of the plate in either direction desired when changing the vertical angle of the guides for angular driving.

The relation of the pile driver guides for angular driving is illustrated more particularly in Figure 8, a series of piles 52 being indicated which may be directly driven through the different angular positions of the guides.

The crane car is provided with the usual crane boom I I having the usual hoist hook operated by a cable I2 driven from the crane car engine I3. This hook overlies the driving attachment in advance of the same and permits the crane car to be swung back to pick up supplies from the flat car and move them into position to be driven by the pile driver attachment, the hook being also available for pulling piles or other parts to be withdrawn when desired.

As previously stated, the casting 29 extends materially above the pivotal supports of such parts at 34 and 35. Thus, when the hammer il has been moved into the upper portion of said casting above said pivotal supports, it acts as a counterweight to facilitate the inclined adjustment of the guides for inclined driving. A stop element 54 is arranged to underlie the hammer when it is in its uppermost position, this stop element being carried by arms 53 swingingly mounted in the casting 29 and controlled manually by a cable 55.

In order to permit the weight guides to be 15 moved at varying angles from the vertical in line with the tower, the plate 22 may be extended 1ongitudinally as indicated at 22X and slightly curved to provide the necessary contact with the plate 24 in the angular adjustment. The extension 2,0 22x of the plate 22 is formed with openings 25X which may cooperate with any of the openings 25 of the plate 24, the pins 26 serving to hold the weight guides in adjusted position either in alignment with the tower or transversely thereof, thus 25 providing for both the vertical adjustments indicated in. dotted lines in Fig. l and in dotted lines in Fig. 8.
