FILE-DRIVER.
Specification of Letters Patent. Patented Apr, 26, 1921,
Application filed October 7, 1920. Serial No. 415,420.
To all whom it may concern:
Be it known that I, NATHANIEL G. Soon, a citizen of the United States, residing in New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Pile-Drivers, of which the following is a specification.
This invention relates to pile drivers of the class known as pendulum drivers in which the leads or guides for the hammer are so supported that they may be set support the leads or guides for the hammers and which comprise a vertical front frame consisting of upright s1de pieces and cross I 7 pieces and an inclined rear frame which braces thefront frame and which consists of trussed, diagonal side beams which are con nected to the front frame by horizontally The ported by the front frame of the shears and consist of vertical s1de pieces arranged a suitable distance apart and faced on their inner sides with channel irons which provide wearing surfaces for the hammer. The side pieces are connectedby yoke blocks set at suitable intervals. The leads are suspended from the top or the front frame of the shears, being provided at their upper ends with a trolley which is adapted to travel sidewise on a rail attached to the shears. Means is provided for moving the leads sidewise in the shears to set them in different vertical planes, and provision is also made for setting the'leads at different angles in the shears within certain limits. When it is desired to set the leads at angles which are more oblique I employ laterally extending lead supports which are connected with the cross pieces of the frame and which maybe so connected with the leads as to hold them securely when once adjusted.
Other features of my invention will be hereinafter described.
In the accompanying drawings:
Figure 1 is a side elevation of a pile driver embodying my improvements supported on a barge.
Fig. 2 shows a rear elevation of the upper portion of the leads.
Fig. 3 is a perspective view of the front of the upper portion of the leads.
Fig. 4 is a front elevation of the pile driver.
Fig. 5 shows a local section on the line A 55 of Fig. 4. l
Fig. 6 shows a local section on the line 6-6 of Fig. 4:.
Fig. 7 is a top plan View. of the pile driver.
Fig. 8 is a detail sectional view on the line 88 of Fig. 4.
Fig. 9 is a detail sectional view, showing the manner of connecting some of the parts.
. Figs. IO-15, inclusive, are diagrams illustrating various positions in which the leads may be set to drive piles at various angles. p
The drawings show my improved pile driver mounted and supported by abarge A, but it may be otherwise mounted and supported in any well known way. The shears of the driver comprise a front frame Band a rear frame 13. The front frame consists of vertical side pieces 6, secured at the bottom to a moon beam O and at the top connected by a cross piece b, over which is arranged and secured a top cross piece T, the opposite ends of which projectbeyond the sides of the shears. Between the top and bottom of the frame there'are horizontal cross piecesD which are bolted to the sides of the frame, as indicated at d, and these cross pieces are formed witha series of holes at, as indicated in Fig. l, The cross pieces D, it will be observed, extend beyond the sides of the shears andthey support laterally extending lead supports E, each of which is formed with a series of holes 6 and each ofwhichis p ivotally connected at e to a cross piece D.
The rear frame B comprises dlagonally arranged beams 0 secured at their upper ends 0 to the front frame and strengthened by truss pieces 0 in any suitable way- The rear frame is also connected with the front frame by connecting pieces c Guy cables F are employed, being connected to the upper ends of the shears and to the rear end of the barge A.
The leads or hammer guides G comprise vertical side pieces g'held a suitable distance apart by yoke blocks H which are bolted to the side pieces 9 at g and furring strips 9 are secured to the sides 9 on opposite sides of the yoke blocks.
In order to provide wearing surfaces for the hammer, channel irons Ii are attached to the inner faces of the sides, indicated in Figs. 5 and 6.
The hammer L is adapted to reciprocate endwise of the leads and to operate on a pile P in well known ways.
To the upper ends of the side pieces 9 is secured ahorizontal top piece 0 from which extends rearwardly and downwardly side pieces 0 which support, at their lower ends, a trolley frame It comprising two short pieces 1" separated by an intermediate piece S which rests on a rail. 8 on the top crosspiece T of the shears.
The hammer L is supported by a cable U which extends over pulleys u, u on the top piece 0 and trolley frame B, respectively, and under a pulley a on the barge to a. winch U operated by an engine W.
By these means the hammer may be raised and dropped in well known ways, but in this connection I would say that a steam hammer or ram of any well known kind may be used instead of a drop hammer.
In Fig. 4, I have illustrated what is known as a hog chain Y which is attached at its opposite ends to the shears and held under tension. On the central portion of this chain rests a block 1 depending from the top I cross piece 6 of the frame. This arrangement serves to support the central. part of the shears frame and prevent sagging.
In order to strengthen the upper part of the leads I provide brace rods Z which are attached at their upper ends to the trolley frame R, extend downwardly therefrom, are then bent inward and downward, at z, and are attached to the furring strips 9 as most clearly indicated in Fig. 3.
i In order to shift the leads and the hammer laterally to drive in different vertical planes, I provide cables X, X which are attached to the upper part of the shears, pass over suitable guide pulleys or sheaves and connect with the Windlass or drum U. By these means the leads and hammer may be shifted laterally in the manner indicated diagrammatically in Figs. 10 and 11 to operate in different vertical planes. When thus adjusted the leads may be pinned to the cross piece D as indicated at m and in this way the leads may be adjusted not only to operate in different vertical planes but also at different angles within certain limits. But by employing lead sup-ports E, I am enabled to so set the leads that batter piles may be driven at any desired angle up to 1" The trolley frame carries a trolley wheel 45 and beyond. WVhen the parts E are not in use they may be folded over upon the cross piece D, as indicated at the upper lefthand side of Fig. 4 and also in Figs. 1()13, but when it is desired to drive piles at a decided angle, one or more of the parts E may be swung outward and secured in place by it 3111 O1 PIIlS 00.
By referring to Figs. 14: and 15, it will be observed that by different adjustments the leads may be set at various angles so that batter piles may be driven at any desired inclination.
I claim as my invention 1. A pile driver comprising shears com posed of a vertical front frame having side pieces, a cross piece secured to the upper ends of the side pieces, a moon beam to which the lower ends of the side pieces are secured, a vertical intervening series of horizontally arranged cross pieces arranged at intervals between the top and bottom of the shears, and which have extensions projecting beyond the side pieces, hammer leads, a trolley frame connected to the upper end of the leads and supported on the top of the shears, means for moving the trolley across the shears, and means for securing the leads to those portions of the intervening cross pieces between the sides of the shears and also to their extensions.
