SECTIONAL DREDGE.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed May 2, 1908. Serial No. 430,460.

To all whom it may concern: 1

Be it known that I, GEORGE E. TURNER, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Sectional Dredges, of which the following is a specification.

My invention relates to improvements in sectional steel dredges, and it relates more particularly to that class of dredges which are used for ditching.

The object of my invention is to provide a sectional dredge, the sections of which will be constructed in such a manner that the machine may be readil set-up for operation in the field, and easi y and quickly taken apart when desired for transportation.

A further object of my invention is to provide a machine which can be easily and quickly converted from a bank-spud machine into one of the vertical spud type and vice versa.

A further object of my invention is to provide a construction in sectional dredges by which the weight of the operating parts may be so supported as to be distributed over a number of the sections of the machine.

A further object of my invention is to improve, simplify and cheapen the construction of machines of this character.

My invention consists in the constructions of parts hereinafter described and set forth in the claims.

In the accompanying drawin s Figure 1 is a side elevation of a device em. odyin my invention. Fig. 2 is a top plan View 6 the sama Fig. 3 is a front elevation of the same. Fig. 4 is also a front elevation showing the auxiliary or side pontoons. Fig. 5 is a sectional view on the line a; a: of Fig. 2. Fig. 6, is a sectional view on the line 1 y of Fig; 2. Fig. 7 is a vertical sectional view 100 ing to the rear, the section being taken just in front of the frame and its support. Fig. 8 is a detail plan view of the su port for the A-frame and its connections wit the pontoon section.

Like parts are represented by similar characters of reference in the several views.

a a re resent a series of hull sections, preferably s own in the drawings as formed in the nature of pontoons. Each of these pontoon sections is preferably constructed of sheet steel open at the top, and suitably braced and stiffened. I have not shown the manner of stiffening and bracing these pontoon sections as any suitable construction for this purpose ma be employed. Secured to the top edge of t e adjacent ends of each of the said sections is a transverse angleiron bar a which bars not only serve as additional stifieners for the sections but also one of the means for attaching the superstructure or frame to the pontoon sections, as hereinafter described. These pontoon sections, a a, are arranged end to end and adapted to support the superstructure and operating mechanism of the dredge.

b I) are a series of angle-iron bars arranged longitudinally on each side of the pontoon sections and extending throughout their length, these bars forming the base of the superstructure or frame work. These bars, 6, are connected together and also to the respective pontoon sections, a a, by plates, 0, c 0 c 0 said plates being riveted to said bars by shop rivets, except at the juncture of the bars, and being connected to the pontoon sections, a, by field bolts. In the drawings I have indicated the shop rivets by black circles and the field bolts by open circles, not only in connection with these plates, but also at all other points where rivets-and bolts are employed. The bars, 6, in practice, are formed of such length as to extend over at least four of the pontoon sections, but in the drawings I have shown one of the bars as of a shorter length and extending over but two of the sections. The

forward bar is the longer one and extends over the first four forward sections. The plate 0 forms the juncture between the two bars and is shown as riveted to the rear bar, Z), by shop rivets and bolted to the forward bar by field bolts. It will of course be understood that these bars I) may be made of any suitable length and extend over as many sections as will be found practicable.

Secured to the cross bars, a of the respective sections, a, and also to the respective plates, 0, c c c 0*, are a series of transverse bents or trusses, at. These trusses, d, are built up preferably in one piece at the factory of angle-irons laced together in the usual Way, although if desired these" trusses might be constructed in separate partsand bolted together in the field. The trusses, d, are constructed on each side of Vertical angle-irons laced together, the outer angleirons, d being bolted to the respective plates, 0,0 etc. by field bolts, and the bottoms of these angle-iron bars being bolted to the respective bars, at, of adjacent sections; through the medium of projecting feet, (Z secured to or forming an integral part of plates d which plates are riveted to the respective angle-iron bars composing the sides of the trusses, as shown. These trusses, d,

are connected together at the top by. longitudinal angle-iron bars, e, corresponding to the bars, 6. The bars, 6, are secured to the trusses, d, in any suitable manner but pref erably through the medium of a series of top plates, f, and side plates, g, which plates aresecured to the bars, 6, by shop rivets eX- cept at the joints, where one-half of the respective plates, f and 9!, will be riveted to' one bar and the other half bolted to the adjacent bar by field bolts in the manner described in connection with the lower bars, 6, and plates, 0, 0 etc.; these plates f and 9, being bolted by field bolt-s to the respective angle-irons composing the trusses. The trusses of the frame are further connected at the top by a series of diagonal bars, h, and at the sides by a series of diagonal bars, h these bars being bolted to the plates, 0, 0 etc. and f and g, by field bolts. The bars, 71., are preferably riveted to a central plate, which will be bolted to the trusses, cl, by field bolts. I

The boom for the dipper, the A-frame, and the spud carrying frame are mounted at the forward part of the machine and I have so supported these various parts that their Weight and strain will be distributed over a number of the pontoon sections. As before stated the angle iron bar, 6, extends over and is connected to preferably four of the pontoon sections and the plate, 0, also extends over several of the sections and is connected to the bar, I), and the said sections. The

A-frame p, is constructed in any suitable manner and is supported upon a frame work made up of two' transverse channels, 70 79 connected together in the usual way. These channels are connected to the plate, 0, by

angle-iron plates 79 and each channel iron has secured at each end laterally extending plates, 19' p5, whichplates extend through slots in the respective plates, 0, and are connected to plates, c connected to the outside of the large plate, 0, each of'the plates, 0, being secured between the respective plates p and 19 which latter platesare secured to opposite sides. of the vertical portion of said beam, These projecting portions, 12 79 and the plates, 0 are adapted to form pivots for braces as hereinafter fully explained.

The turn-table, m, for the boom is supported on a similar frame work made up of channel irons, m m su tably connected tog ther. This Support is secured at each end the usual. way of channel iron or I-beams,

j j suitably laced together. These beams are supported by vertical angle-iron supports, j f. The vertical supports,j are connected tothe respective plates, 0, and also to the plates, 0 at their lower ends, and at their up er ends are secured to the channel irons, j j through the medium of plates, j. Thetop beams, j f, are extended laterally and arranged at their ends to receive the spuds, 0. Arranged between these beams is a channel shaped guide, j and the beams are tied together at their respective ends by plates, j so that the respective spuds will be confined between this guide, j, and the blocks or plates, j, in the ends of the beams but per mitted to slide freely therethrough. These spuds are provided with the usual means for raising and lowering them, Pivotally' con-. nected to the lower ends of each of the spuds is a brace 04, which will be pivoted to a pin or bolt, 0 extending through the laterally projecting plates, 72 p and also through the plates, 0 'connectedthereto. These spuds are arranged to be used either as bank-spuds or vertical-spuds. In Fig. 3 the spuds are shown in position for use as. bank-spuds in which position the braces, 0 are employed. In Figl'4 the spuds are shown in position for use as vertical spuds, in which position of use the extra side pontoon sections, a a 5 are employed.

The auxiliary side pontoon sections, a are constructed in any suitable manner but preferably similar to the main sections, a a.

They are secured to the main sections preferably by the same bolts which Secure the plates, a 0 etc. to the main sections by simply extending the bolts through these side sections. The purpose of these pontoon Sections is to add additional boom capacitywhen the spuds are used in the vertical position, a somewhat longer boom bein used for the purpose of cutting a wider distance than would be possiblewhen the spuds were used as bank spuds. When these side pon toon sections'are used the braces, 0 willbe removed and other braces, 0 0- will be connected to the pivotal point, 0 and also connected to the side ontoons in any suitable manner. One of t ese auxiliary side. pontoons on each Side will, have connected there- 130 OX, 0 into which the respective spuds, 0, will be rec'eivedthe feet 0", of hese spuds having been first removed. When the pQn-a toon sections are used the structure is further braced and stiffened by brace rods, 0". These brace rods are secured at their lower .ends to outer sidesof-the side sections and at theirupper ends to the plates j.

It will be 6. 11 from the construction described that I have provided a sectional dredge whichcan be easily set up in thefield and taken apart for transportation. By the construction it is possible to-neadily detach any one of the pontoon sections, a, and re move it for the purpose of repair. Also by the construction employed the weight and strain will be distributed over a wide range. For instance, in the forward part of the machine it will be seen that the frames. or supports for the boom turn-table, the A-frame, and the spud carrying frame are all secured to the large plates, 0, and these plates are themselves secured to a number of pontoon sections so that the weight of these various parts and the strains brought upon them will be distributed throughout the different sections.

While I have shown the sections of the hull as formed of pontoons, yet it is obvious that the hull might be made up of openended sections, suitably connected together, so as to form when assembled a continuous hull; the respective end sections, of course, being closed at one of their ends. If desired, partitions could be inserted between the respective sections to provide not only a series of water-tight compartments, but also to brace and strengthen the hull. The hull thus formed would also be braced and strengthened in any other suitable manner to give the required strength for supporting the machinery, such as the winding drums, engines, etc.

In the construction shown in the drawings, the superstructure is so formed as to assist to stiffen and strengthen the hull, but this construction might be modified and the hull so braced and stiffened as to carry the load of the machinery outside of the boom, A-frame and spud-carrying frame, so that it would be necessary to provide but a light super-structure for the purpose of supporting the roof and inclosing walls of the cabin.

Having thus described my invention, I claim:
