Description
TRUss-FRAME non BRIDGES. i
specification of Letters Patent No. 26,680, dated `January` a, iseo.; j 1 p To all whom 'it may concern:
Be it known that I, ENocH JACOBS, of Cincinnati, in the county of Hamiltonand VState of Ohio, have invented a new and Im-` proved Truss-Frame for Bridges and for other Like Purposes, which I verily -believe has not been used or known prior to the in-` vention thereof by your petitioner hereof; and I do hereby declare that the following is a full and eXact description thereof, refer-1` ence being had to the accompanying draw-` ings and references marked thereon.
The nature of the invention consists in the combination of double` angle iron rails with certain arrangements of vertical and oblique braces and tie rods hereinaftendescribed. p c
Figure 1 of the drawings represents an elevation of the truss or a length thereof. Fig. 2 represents a vertical longitudinal section through the central line of the truss the upper rail 3 being separated from the braces and tie rods. Fig. 3 represents a horizontal section through the truss in the line m, w, of Fig. 2. Fig. 4 represents the interlocking of zigzag braces with each other at their intersection. Fig. 5 shows the reception ofthe brace tubes in the inner part of the double angle iron rails. Fig. 6 shows the method of twisting the oblique braces atthe crossing to avoid notching them together.
Similar letters represent the same devices p in all the drawings.
A represents the upper and A the lower rail of the truss, the hollow parts facing each other in Fig. l and as seen in the sectional view Fig. 5.
B, B, B, &c., represent" the brace tubes. C, C, C, &c., the vertical tie bolts. D, D, D, &c., the zigzag cross braces.
This truss consists of few. parts, and possesses great simplicity and strength.` The greatest point `perhaps inthe composition of the truss consists in the use of the double angle iron for the upper and lower rail. This rail is from a single bar rolled in form by passing it several times through `each of several rollers of a series, until it is brought into the U form, but is left much thicker and heavier at the bend than near to the ends, as shown in sectionin Fig. 5, where the rails are represented as embracingthe .structed constitutes three `sides of a qua" rangular iron pipe, one of ltlneyshorter` sid zigzag braces and the tubular` braces. These" strength to prevent swaying from ,sideytof l Fig. 2, and uponl the inner faces Mof eacho y the truss frame` are made to cross each]"otlfier` `weakening of the metalI.havefsubstitu for bridges and `foryothelsimilarpurp brace-tube B. `Theianglefironllthus icon" b eing left open forxrcceiving theobli(iuefor` rails are left veryn lheavy over the" bendft allow for the holesto be drilledfoi' passing the screw bolts, and also "to giveadditional side.` The `greater lenggthyof` this section" o the rail `is in its verticalgisides, ashere 111s needed its greatest `strength ltol bearlltliej` weight that may be put upon it.

What I claim as my invention and desire 5 to secure by Letters Patent is,
