SUSPENSION-BRIDGE Specification of Letters Patent.
Patented Mar. 15, 1910.
Application filed January 13, 1909. Serial No. 472,111.
T 0 all whom it may concern:
Be it known that I, WILLIAM ALEXANDER W001), a citizen of the United States, residing in' the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Suspension-Bridges, of which the following is a specification.
This invention relates to improvements in suspension bridges and has as its object a bridge which may besuspended from a cableway, is flexible in its structure and may be adjusted on said cableway as to its position. Such a structure finds application for example, in connectionwith railway and other construction work where it is desired to fill depressions and make embankments. Heretofore, if the filling is done from cars running on tracks, the tracks have'extended only to the edge of the depression and unless care is taken, the cars are liable to run off the track into the depression or else expensive trestles have to be constructed extending over the depression. In the first instance, even if the cars do not leave the track, the dumping of material is not done in the most effective place and in the second instance, the trestle is itself buried in the dumped material. thus adding the'cost of the trestle to the cost of erection. I obviate both of theseobjections by my invention in which I provide-a means for extending the track over the depression without building atrestle, for dumping the material where required and for moving my structure along the track or way as the work progresses.
In the following I have described, in connection with the accompanying drawings, one means illustrating the application of my invention, the features thereof being more particularly set forth hereinafter in the claims.
In the drawings Figure 1 is a side elevation of a structure illustrating my invention as applied to railway construction work. Fig. 2 is a plan view of the structure shown in Fig. 1. Fig. 3 is a side elevation of a portion of the structure shown in Fig. 1 on a larger scale. Fig. 4: is an end view of one of the suspending means on an enlarged scale. 5-is-a side view of the parts shown in Fig. 4, parts being broken away. Fig. 6 is a plan view of a portion of the track structure. Fig. 7 is an enlarged detail View of the suspending means. Fig. 8
'to each other by is an enlarged detail view of the clamping means, and Fig. 9 is a sectional end view of the structure shown in Fig. 8 along the line A-B.
Similar numerals of reference indicate similar arts throughout the several views. 1 indicates a fixed tower on one side of the depression or cut to be filled, as shown in Fig. 1. ,2 indicates a movable tower on the other side of the depression, mounted on wheels 3, 3 adapted to run oil-tracks 4, 4, resting on embankment 5.
6, 6 are cables passing over towers 1 and 2, guyed back to a deadman 7 at one end and fastened to pulleys 8 at the other end. Pulleys 8 are connected by suitable take-up ropes 9 with pulleys 10 which are in turn guyed back to a deadman 11. Pulleys 8 and 10 in connection with take-up ropes 9 afford means for adjusting the tension of cables 6, 6 and for taking up the slack therein. Tower 2 may be further held in place by guy lines 12, 12 fastened in any convenient manner.
13, 13 are tracks on embankment 5 adapted to support a suitable dump car or the like (not shown) and running through and I under tower 2.
14, 1a are suspender means depending from cables 6, 6 and comprising a wheel 15 adapted to travel on cable 6 and journaled in a suitable bracket 16, a rope 17 depending from pin 18 in bracket 16 and in turn supporting a pulley 19 connected by means of a takeup rope 20 with a pulley 21 provided with an eye 22 adapted to support a bolt 28 passing through and supporting a cross'beam or tie 24:-
25, 25 are timbers or ways extending from one cross-beam or tie 24 to the next, the ends of timbers 25 overlapping on cross-beams 21, as shown in Fig. 5, and being fastened ins 26 in such manner as to form a fiexib e joint. Timbers 25 are prevented from moving lengthwise over cross-beams 24;, by pins 27 passed down through timbers 25 and projecting below on each side of-cross-beams 24, as clearly shown in Figs. 1 and 5. Sidewise movement of timbers 25 is prevented by blocks 25 timbers and are arranged to be in alinement with and in continuation of tracks brackets and being pivotally connectedtherewith by a suitable pin 31, so as to form a flexible connection. Clamps 32, 32 similar in construction to clamp 33, shownin side view in Fig. 9, are adapted to clam over cables 6 and to hold a stra 34 bolte thereto by suitable bolts 35. trap 34 is provided with an eye 36 into which a cable or rope 37 is adapted to take, the other end of rope 37 being clamped to cables. 6 by any suitable clamps 38. Clamp 33 is adapted to clamp over cables 6, straps and 34 being pinned thereto by a suitable pin or bolt 39. in 39 carries a link 40 connected by rope 41 with turnbuckle 42 in turn fastened in any convenient manner to the base of tower 2. In operation, with the bridge in the position shown in Fig. 1, the dumping cars may run from tracks 13, 13 onto tracks 29, 29 and then out onto the bridge structure where they may dump their loads. When the depres sion has been filled up to grade beneath the bridge structure, the clamps 32 and 38 and the rope 41 may be loosened and the bridge structure slid or pulledalong cables 6 to its new position and fastened there. The suspending beams 14 may then be adjusted to accommodate them to the deflection of cables 6, tracks 5 extended and the work proceed as before. From time to time the guys holding tower 2 in position may be loosened and the tower slid along to a new position, the cables 6 being loosened and taken up again by pulleys 8 and 10 and take-up ropes 9. In-
stead of moving the whole bridge structure,
it is obvious that when the depression has been filled u to grade beneath said structure, the bots 23 may be detached from cross-beams 24 leaving the track in place and the suspen ing means moved along cable 6 to the new -posit1on and fastened there, the trackway structure being extended as hereinbefore described and connected with the track'way detached, so that instead of building new sections of track, as the work progresses, the portions detached from the suspended structure may be used for the permanent track. It is thus seen that the bridge may be advanced as the work progresses, always atfording means for dumping .in the easiest and most satisfactor manner and at a minimum of expense. ll of the parts being flexible and the suspending means being adjustable as to length results in a structure extremely well adapted tothe purpose. Instead of one tower being fixed, as shown .in the drawings, both towers may be movable and a suspension bridge, structure of the type described provided at'either end of the cableway. The towers, or one of them, being movable permits the use of a much shorter tower than would be necessary if both towers were fixed, the moving of the tower ad-. vancing the fulcrum nearer the work and hence shortening the span, the take-up ropes 9' taking up the cable and hence decreasing the deflection thereof.
It is obvious thatthe details of construction'may be readily varied without depart.
ing from the spirit of the invention and I do not restrict myself to the details as shown and described.
