This invention relates to new and useful improvements in pile driving machines.

The invention has to do with a pile driving machine particularly adapted for the driving of concrete piles for highway bridges, but is not necessarily limited to such use.

I have done considerable experimenting in pile driving on highway bridges and the like with the type of pile drivers now in general use and difliculties in the use of such machines led me to the invention of my present apparatus. While using other pile drivers I found difficulty in moving from one piling to another due to the fact that such machines are mounted on skids or rollers and when the ground is not level a great deal of cribbing and blocking is necessary before movement can be made. I found that the machines which were. available were not flexible enough and could not be economically and successfully used in this character of work, and particularly in crossing a stream or body of water. r

It is customary at present to use both wood and concrete piling in highway and similar construction. In the present method the individual piles are first driven to a depth to get suflicient bearing to carry the load. This may result in the top of the piling being either below or above grade, and in the firstv instance the piling would have to be built up to grade, and in the second instancewould have to be cut oil to grade. In my method the piling is first driven to grade and if it will not go to grade it is cut off to grade. A temporary wooden cap is placed across the piles which are arranged in a transverse row. If a pile has not reached sufficient bearing and it is necessary to drive it further down than to grade, this can be done with my invention after the machine passes over it, by turning the machine around and driving it from behind. 1

One of the objects of the invention is to provide a pile driving machine which may Serial No. 542,057.

beam to another in a rapid and simple manner.

Still anotherobject of the invent-ion is to provide improved means for holding the leads rigidly in place and yet permitting ample adjustment of the machine to different posio0 tions.

A construction designed to carry out the invention will be hereinafterdescribed together with other features ofthe invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings in which an example of the invention is shown, and wherein:

Figure 13 is a horizontal cross-sectional view taken on line 13-13 of Figure 9.

In the drawings the numeral 10 designates a base frame and 11 a rectangular platform rotatably mounted thereon. The base frame is provided with forward hold-down or retaining devices 12 at each side and similar devices 13 at the rear on each side of the frame. The frame is madeup of a transverse front bolster 14, a rear transverse bolster 15 and connecting sills 16. It is preferable to make these frame parts of I-beams as is clearly shown in Figures 2, 3 and 6.

Each forward retaining device includes a pair of hangers 17 secured to the under side of a mounting plate 18 which is fastened to the bottom of the forward bolster 14 at the outer end thereof. A pair of rollers 19 are journaled in the hangers as is best shown in Figure 11. The trunnions 20 at the ends of each roller 19 pass through channels 21 depending from the plate 18 and having their fiat sides secured to the inner sides of the said hangers. The channels are turned so as to form shoes with their lower flanges engaging under the top flanges of I-beams A andB, whichare mounted in parallel and over-lapping relation on the headers or caps O of the false work. Each roller passes through a central spacer or shoe 22 cutfrom a piece of I-beam so that its lower flanges will engage under the adjacent flanges of the beams A and B.

It will be seen that theshoes 20 and 22 will resist upward displacement of the frame 10 and that the rollers will providebearings on'which the base frame'may be propelled. It will be noted that the rollers 19 will travel on either of the beams A or B or on both of them. The beams are placed on the caps one in advance of the other with their ends over-lapping so that the machine may be propelled therealong from one beam to the other as the work progresses. The rear retaining devices 12 are similar to the forward ones and each includes a mounting plate 18 secured to the under side of the rear bolster 15, hangers 17, a single roller 19 journaled in the hangers, and shoes 21 and 22. The retaining and supporting devices not only provide for easy propelling or movement of the base frame, but prevent its displacement from the beams A and B when the platform 11 is swung under a load.

The platform 11 includes a spider 23 secured to the longitudinal side members (Figures 4, 5 and 6). The spider has a pivot box 24 in its center. An inclined spider25 is fastened in the upper portion of the base frame 10 (Figures 2, 5. 6 and 7) and also has a central pivot box 26. A headed pivot pin 27 is inserted in the box 24 and engages in the box 26. The purpose of this pin is to prevent movement of the frame 11 laterally in a horizontal plane and to confine its horizontal movement to that of rotation about said pin.

A circular track 28 concentric to the pivot pin 27 is secured on top of the frame 10 and under the frame 11. The frame 11 includes diametrically opposite segmental housings 29 as is best shown in Figures 3, 6, 7 and 8. These housings are confined between the longitudinal side members of the frame and include complementary channels 30 which are suitably secured to cross-members 31 and 32 (F lgures 2, 3 and 4). The channels 30 extend under the top flange of the track 28 as is shown in detail in Figure 8, and rollers 33 journaled in the channels ride upon the track 28, thus supporting the frame 11 and carrying the entire load thereof. -By this arrangement the frame 11 is freely rotated and the spiders, the track and the housings constitute a turntable.

A suitable boom 34 is hinged at its lower end to the forward end of the platform 11 and this boom is operated and supported in the usual manner by a suitable hoisting engine the details of which form no part of the present invention. The pile driving leads 35 are suspended from the upper end of the boom inthe usual manner. In order to brace the lower ends of the leads and hold the same in the proper position a structure has been designed for this purpose, which is clearly shown in-Figuresl, 9and 10. A horizontal yoke 36extends rearwardly from the leads and is supported by braces 36 attached to the leads. l n angle bar 37 is secured to the rear side of the yoke and has attached thereto a segment 38. The segmentis disposed concentrically to a pivot bolt 39 passing through eyes 40 secured to the ends of brace bars 41.

The segment is secured at its ends to the endsof the bar 37 by rings 42 thus permit: ting a swinging movement of said segment. Each bar 41, is provided with a keeper 43 which embraces the segment and prevents the segment from falling away from said bars. By this arrangement the segment, the bar 37 and the yoke 39 maybe swung in a horizontal planeand rotated with relation to the brace bars 41. The inner ends of the brace bars are mounted to slide in keepers 44, (Figures 1, 2, 3 and 10) fastened on each side at the forward end of the platform 10. Set screws 45 mounted in the keepers, are employed to fasten the brace bars in position.

It will be seen that by reason of the holddown or retaining devices 12 and 13 the frame 10'can not tilt and thus the platform 11 may be freely swung to any position so as to suspend the leads 35 either forwardly or rearwardly or at any angle on each side of said frame. The turntable of course, prevents the platform from tipping under its load. The adjusting means shown in Figure 9 permits the leads to be swung at any desired angle either in a horizontal or vertical plane and fastened in such position by tightening the set screws 45.

It will be seen that the leads may thus be kept parallel to the caps C. As before stated the beams A and B are placed on the cap C one in advance of the other and are overlapped. The rear ends of the beams B as shown in Figure 1 must be held down to prevent tilting when the frame 10, boom 34 and leads 35 are under a load. For this purpose cables 46 are fastened aroundthe piles D and looped over the ends of the beams so that each will engage in the hook 47 of a jack 48 support-ed on a heavy plank 49 (Figs. 1 and 10) extending from one beam to the other. By adjusting the jack 48 the loop of the cable 46 is tightened and the end of the beams thus held in place. For swinging the platform 11 a cable 50 is coiled about the track 28, the ends of this cable being crossed and passed through pulleys 51 and then coiled upon drums 52 connected with the engine of the machine so that by rotating either drum the cable is wound thereon and unwound from the other drum, thus rotating the turntable. Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the scope of the appended claims.

Having illustrated and described a preferred form of the invention, what I claim, is

1. In a pile driving machine, longitudinal flanged supports having their adjacent ends overlapping, a base frame, rollers supporting the frame and arranged to engage either or both of the overlapping supports so as to ride from one support to the other support, hold-down devices carried by the frame for engaging either or both of the overlapping supports, and a platform rotatably mounted on said frame.

2. In a pile driving machine, a base frame, hangers at the front and rear ends of the frame on each side thereof, rollers ournaled in said hangers, flanged supports in which said rollers travel, shoes below the rollers eX- tending under the flanges of the supports, and a platform rotatably mounted on the frame.

3. A pile driving machine as set forth in claim 2 and a spacer between each pair of hangers having projections on each side extending under the flanges of the supports.

4. In a pile driving machine, a base frame, a platform rotatably mounted on the frame, a support on the platform, leads suspended from the support, a yoke mounted on the leads, a segment connected to the yoke, braces pivoted to the yoke and attached to the platform, and clamps mounted on the braces and engaging the segment.

In testimony whereof I aflix my signature.
