This invention relates to overhead monorail" systems, and more particularly to certain improvements in the supporting structure therefon.
and in which all. requirements for. speed, safety, strength, comfort and appearance arefully met. An important object of the present invention is the provision of a supporting structure for amonorail or overhead system which will make possible, feasible and practicable" the location of such supporting structuresalong the center'park strip, or other narrow strip, of present day free ways, so-called. In other words, this invention has-to do with a supportin'gstructure which can most advantageously: be placedalong the sameright-of-way required for a freeway without any increase in the'w-idth thereof thus making possible a very great saving inthe cost for right-of-way for such a system.
These advantages and savings are made possible by a special design of super-structure, and
particularly a V typeof tower or'support which I have invented, and which requiresa relatively narrow strip, or right-of-way, for the base or supporting foundation for such a system. In fact, the space or park strip between the two road-ways of travel in the present freeway or speedway will be adequate for the location of the supporting base or foundation for a practicable monorail or overhead railway system;
Not only is the V' type of supporting structure considered to be strong, practicable,- economical and eflicient, but it lend itself to neatness and stream-lined attractiveness as well.
'Other advantages and functioning features will be recognizedin the following. moredetailed de scription of practical embodiments of the invention, as illustrated on the accompanying two sheets of drawings, in which:
Figure 1 is a side view showing a V support, with its foundation, and. with rail-supporting girders supported thereon, parts being broken away and shown in section;
Figure 2 is an end view of such, looking at Figure 1, on the vertical line 2-4 on Fig. l

Figure 6 is an enlarged. sectional view of one.
of. the adiustment mechanisms seen in one of.
z the arms of the V- structure in" Fig. 4; and also seen on.li'ne66 on Fig. 5; and
Figure 7" is a. sectional detail, taken on line. 1I, Fig. 5; and
Figure 8 is a fragmentary, sectional view of one end of the T-top of onev of the V-arms of the: reinforced concrete structure.
Referring: more in" detail to the drawings, this invention involves. the. use of a \l-form of sup-- porting structure for monorail or overhead rail way system. This requires a relatively narrow foundation or anchorage strip in the ground. The V-arms diverge upwardly to points of connection with the overhead girders on" which" the rails are-mounted. Each of the V-arms at its upper end is in the form of a T, and the railsupporting girders are secured to-the'outer' ends of said T. This V-form of supporting structure for a monorail or overhead system can be of. steel, or reinforced concrete design. shown both types of construction in theaccompanying two sheets of drawings, which I will now describe.
Broadly considered, the V-form of structure includes" two supporting arms, as 10, F0, as a supporting unit, connected together at their lower' ends and suitably anchored, as generally" indicated at H, with a substructure, generally indi-' cated at I 2, to give the necessary supporting baseandanchcrage strength for the load to be carried. This foundation and anchorage is again referred to.
Upon the upper ends of said arms, which and consisting in the main of two- I-beams or girders I1, l'i, secured to-the outer ends of the T-tops of said V-arms, as seen in Figs. 2' and 5, with such additional reinforcing connections therebetween as may be considered necessary for each job, but not necessary to be here shown.
This general structure, including the V'-arms; with the l'--tops at the upper ends thereof, constitutes, in the main, the invention of this application. Someof the details of construction of said arms and of the anchoring and supporting means, as shown for illustrative purposes, will now be described in connection with the drawings.
In Figs. 1, 2 and 3,. a steel structure is illustrated, the V-arms thereof being fabricated as indicated in. Fig. 3, which shows a cross sectional view taken on line 3-3 of Fig. 2. In this showing, an H-form or body, in cross section, is shown, designated as a: whole: I4; This:
I have H-form or body is formed of two T-members, as I4, l4, connected together, edge to edge, with a plate I5, welded therebetween. This form of construction is continued upwardly to form the top or T, upon which the rail-supporting girders are mounted. In Fig. 2 are shown curved T- members, as 54'', I4", with a triangular plate inserted therebetween and welded thereto, as indicated at l5". The I-beams or girders l1, II, at the opposite ends of the T structure, are secured to the outer ends of short I-beams l0, l0, secured in place against the T-members l4", I4", as seen in Fig. 2, thus supporting the main track-supporting girders ll, ll.
On the outer, opposite sides of said H-form or body, as here shown are two reinforcing members, as |6, |6, riveted or otherwise secured thereto, as may be desired. These finishing plates also give additional strength.
Secured to the outer main girders l1, H, are the rails l8, b8, mounted thereon, and suspended from which a car C, indicated in light broken lines, runs, as indicated in Fig. 2 of the drawmg.
It will be understood, of course, that any suitable steel construction can be used to form the V-arms, and also theline members or girders supported thereon, and upon which the rails are mounted, can be used. The present showing is illustrative.
The foundation and anchorage structure as here illustrated includes a concrete block, as l9, upon a larger concrete platform, as 20, which in turn is supported on suitable concrete pillars, as 2|, 2|, all under ground, or below the surface. The concrete platform or slab 23 has imbedded therein reinforced H-members, as 22, 22, with which are connected tie bolts, as 23, 23, extended up through the block it, and anchored at their upper ends in a steel plate structure, resting upon the concrete block l9, and consisting of upper and lower steel plates 24 and 25, with vertical spacing steel webs or members, as 26, 26, therebetween, all as illustrated in a general way in Figs. 1 and 2. It will be understood, of course, that many different types of anchoring foundations for the small end of these V-arms of the supporting structure can be used, after the general idea is thus presented.
Referring now to Figs. 4, 5, 6 and 7, I will describe an embodiment of the invention in which the V-arms are made of reinforced concrete. The V-arms here are designated 39, 30, with re-- inforcing rods 3|, 3 indicated therein. Said V-arms are precast with the rods therein and left projecting from the lower ends of the arms, said arms being adapted to be lifted into place in a manner hereinafter again referred to.
The block 32, formed upon the platform 33, Fig. 4, and supported on concrete pillars 34-, 34, are all formed below the surface as a supporting foundation in a well known manner. Two segments of curbs are indicated at 35, 35, Fig. 5, to show the relationship of the roadway or speedway at opposite sides of the supporting structure.
The upper ends of said V-arms are also provided with reinforced concrete T-tops, designated as a whole 35, for supporting the rail-carrying girders, as 3'1, 31, and on which the rails 38, 38 are mounted. Referring to Fig. 8, the T-form is provided with reinforcing steel rods, as 40, connected at their outer ends with an end member or head 39, and to which the girder 37 is secured by welding, or otherwise, as may be determined by, the requirements.
Referring now to Figs. 4 and 6, the reinforcing rods 3|, 3|, in the V-arms 30, 38-, are provided with means for making certain longitudinal adjustments for alinement purposes as said V-arms are put into place upon the block 32. This is accomplished in the following manner: The substructure, including the concrete pillars 34, 34, platform 33, and block 32, are formed as any foundation structure is formed out of concrete, with reinforcing and anchoring steel frames, as 4|, therein, and with connecting bolts 42, 42 extending therethrough as indicated in the sectional portion of Fig. 4, said bolts projecting from said block 32. The V-arms 3e are formed or cast separately, with the reinforcing rods 3i therein, as indicated, and projecting from the lower ends of the cast V-arms. These V-arms are then lifted into place and the ends of the reinforcing rods 3|, 3| are coupled to the projecting ends of the bolts 42, 42, by coupling means, as indicated in Fig. 6. This mechanism as here shown, includes a coupling member 43 on the end of rod 3|, formed to receive it as indicated, said coupling 43 being designed to screw over an intermediate member 44 which is externally threaded to receive the coupling member 43, and is also internally threaded, to screw on to the threaded end of the bolt 42. A lock nut 45 is shown on the bolt 42 for locking the parts securely together after adjustments have been made.
.When the V-arm has been thus cast and lifted into place, and the reinforcing rods therein are connected with the bolts 42, in the foundation block 32, and all adjustments have been made for accuracy of position of the V-arms, then the juncture of the lower end of the V-arm and the block 32, upon which it is mounted and secured and adjusted, is sealed in with forms and concrete, to form an integral structure around said coupling means, as seen in the sectional portion of Fig. 4. This is simply one means for getting accuracy in the construction when reinforced concrete is used for V-arms in the supporting structure for the rail-carrying girders 3?, 37, at the outer ends of the T-tops of said supporting structures. a
The drawings are illustrative of the invention involved herein, and no attempts have been made to indicate details of construction and arrangements, knowing that braces, and strengthening means can be used as may be required for each job. 7
While I have shown and described two different embodiments of the invention-fabricated steel structures and reinforced concrete structures, I am aware that many changes in the details of construction and arrangement can be made therein without departing from the spirit of the invention, and I do not, therefore, limit the invention to the showing made for explanatory purposes, except as I may be limited by the hereto appended claims.
