Description
tait@ tatrs @anni @ffica- IMPROVED SUSPENSION *BRIDGl-l.
Uilp Schaub ref-etat in in tipa trttets @dat mit making part nf tige smic.
`T0 ALL WHOM IT MAY CONCERN: by. Beit known that, A. S. HALLIDIE, of San Francisco, in the count-y of San Francisco, and State of California, have invented a new and improved Suspension-Bridge; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference beinghad to the accompanying drawings, forming part'or this specification, in' which- Figure 1 represents a. side elevation of my improved suspension-bridge.
Figure 2 is an inverted plan view of the same.
Figure 8 is a vertical cross-`section of the same, the plane of section being indicated by the line :u fr, iig. 1.
Similar letters of reference indicate corresponding parts.
This invention relates to a suspension-bridge which is suspended from strong cables or ropes that are attached to substantial posts or pillars, andwhich is strengthened by means of suspension-rods, which connect the aforesaid cables with 'the gir-ders upon which the planking rests, and by braces which connect the cables on each side of the bridge with 'each other, so that thereby the bridge is made to be very strong and'durable, and `capableof sustaining heavy weights and of withstanding the force of strong gaies. i
A represents-the pillars, which are made of metal or other suitable material, and which a're set upon foundations B of strong masonry. Four posts are arranged on each bridge or section of bridge, one in each corner of the same, as is clearly shown in iig; il. C C are the cables., of which two are used on each side of the bridge. .Each cable is secured to the upper end of one post and to the lower part of the opposite post on the same side ofthe bridge, the cable not being stretched very tight, but being slightly curved,.as is clearly shown in iig. 1. One
l end of each cable may be secured by means oi' nuts in the post to allow of its being adjusted, t'. e., more or less stretched or slackened. The cables C C, which are made of wire or other suitable material, when thus hung, cross each other on each side ci the bridge, as seen in iig. 1, and are-securely connected at the'crossing by the coupling a. To them are secured the suspension-rods D, upon the lower ends of which the girders E rest. These metal suspension-rods are secured by means of pins to ears or lugs which project from rings a, which are arranged firmly around the cables as shown. The suspension-rods D are arranged vertically7 and are secured,
Y alternately, to one and to the other cable, asis clearly shown in iig. 1. The lower end of each suspension-rod is provided with a screw-thread, so that it may receive a nut, b. The girdersrE, which are made of metal as shown, are arranged across the bridge, and are provided at their ends with flanges or projecting side pieces c c, which rest upon the nuts as shown. By means of these nuts, or their equivalents, such as keys, pins, or shoullders on the rods D, the position of the girders may be adjusted at pleasure. The planking F is placed upon the giiders in the usual'manner. On the sidesof the flooring stringers d d may be arranged, as shown in iig. 3. G G are diagonal rods which are arranged between the cables, and are attached by means of bolts to ears on the rings a, as is clearly shown in iig. 1. They are tted in these ears so as to be adjustable, or are coupled in'the centre by'a right and left nut for that purpose. By the use oi' two cables on each side of the bridge the L bridge cannot be 'overturned by a heavy gale, nor can it be excessively shaken or vibrated thereby, as the cables neutralize all such motions. The bridge is thus fully as strong and substantial as is necessary for all practical purposes, and can be adjusted or repaired with ease. I t is so arranged that should even one of the cables on each side,` or seme of the suspension-rods break, or some of the girders fall, the .bridge will still be suspended from the remaining cable and rods, and the planking supported by the remaining girliers.
r `Having thus describedmy invention, whatI claim as new, and desire to secui'efby Letters Patent, is
1. The cables C C, in combination with the suspension-rods D D and girders E E, all made and operating substantiallyas herein specified and described, and the rods D being made adjustable as set forth.
2. The combination ofthe adjustable cables C C, posts A, rods D, gliders E, and adjustable braces G with each other and with the dooring F, all being made substantially as herein spcciied and described.
The above'speciiication of my invention signed by me this 6th day of March, 1867.
