BRIDGE.
APPLICATION FILED MAR. 13, 1917.
1,253 8@9 Patented Jan. 15, 1918.
Snumzloz invrr Application filed-March 13,
To all whofnt it mdy concern 1 Be it .known thatx-l, Hnnirr Gnnnninui citizen of the United Statiesjresiding at Garne1','in the county of Hancock-andState of Iowa, have invented certain new and useful lmprovements in Bridges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled iii the art to which it appertains to make and use the same. j 'i The invention relates to improvements in bridges. 1 1 f i The object of the present invention is to improve the construction of bridges and to provide a simple, practical and .efiicient bridge of strong, durable and comparatively inexpensive construction, which will be selfsupporting and in which the means for supportingthe bridge intermediate of the ends thereof will be in proportion to the weight to which the bridge is subjected.
With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims here to appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. I
In the drawing:
Figure 1 is a side elevation of a bridge constructed in accordance with this invention.
Fig. 2 is a horizontal sectional view on the line 22 of Fig. 1.
Fig. 3 is a detail sectional view illustrating the manner of mounting the ends of the truss of the bridge.
Like numerals of reference designate corresponding parts in the several figures of the drawing.
In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, the bridge comprises in its construction a truss composed of a horizontal top member 1, inclined end members 2, a central vertical strut member 3 and a horizontal connecting beam or member 4 supportin the strut member and the flooring 5 of the %ridge and suitably secured at its ends to the inclined end members 2 at points adan rpm Specification of Letters Fatent. i

arms oi portions 6, which extend below the connecting' beam 4 and the floor 5 of the bridge. The inclined end members 2 are ?atented Jan, 15,1913;
i917. seriainousas'oif suitablysecured at their oppositeterminals to the top membcrl, which is braced adja- V cent to its ends by inclined braces7'exte1 1'd mg across the angles formed by the inclined end members and the top connecting member. The truss constitutes the main frame work of the br dge and it may be varied in dimensions to provide a bridge of the deslred size and may, be internally bracedto secure the requis te strength ofthe frame work which may be constructed of any suitable material, either wood or metal or. a
combination of both. j
The bridge is supported by inclined levers 8 consisting of longitudinally disposed beams extending from the end portions of the truss inwardly and terminating short of the center thereof and fulcrumed adjacent their outer ends on piers 9 of concrete or other suitable material. The piers 9, which are tapered or approximately triangular in end elevation, may be conveniently located at opposite sides of a stream or other place to be bridged, and the levers 8, which are located at opposite sides of the bridge, extend inwardly and outwardly from the apexes of the transverse piers 9 and have relatively short outer arms and relatively long inner arms. The outer arms receive the depending lower terminal portions of the inclined members 2 which rest upon the outer arms adjacent to the apexes of the piers, and the inner arms 8, which extend to the central portion of the sides of the bridge. The levers may be secured to the frame of the bridge by yokes 10 or other suitable fastening means, and the beams, which consti tute the levers, may be provided with sockets 01' seats 11 in their upper faces to receive the lower ends 12 of the inclined end members of the truss of the bridge to form a fulcrum or bearing of the same if desired. The remaining weight of the truss rests upon the outer arms of the inclined levers and the latter may be proportioned to produce the at the center of the bridge will increase with the Weight to which the bridge is subjected. In practice the bridge will-besuitablyanchored and the approaches to the bridge will be built up substantially flush with the floor. 1
As this is well understood in the construction of bridgesof this type, illustration thereof is deemed unnecessary. lVhat is claimed is:
inner and outer arms, the outer-arms receiv-V ing and support ng the depending arms or portions of the truss and f-the inner arms of the levers extending beneath and sustaining the "weight of the bridge at the center thereof.
2; A bridge of the class described includp 7 strut interposed betw-en the upper and in a. truss constitutin tlie frame work of b D i the bridge and having do\'v1iwardly project ing terminal portions'orarms, piersforni- "ing fulr'zruins,v and longitudinally disposed inclined leversv fulcrumed intermediate of their endson the piers form relatively short outer arms and relatively long inner arms, the outer arms receiving the depending arms or. portions of the ends of the truss and the inner arms extending beneath the truss and supporting the bridge at opposite sides of the center of the same.
3. A bridge of the class described including spaced tapered piers forming fulcrums,
inclinedlevers supported upon the piers and extending inwardly and outwardly therefrom to provide "relatively long inner arms and relativelyshort outer arms, and a truss composed of inclined end members" having depending terminal portionssupported upon the outer arms of the inclined levers, an upperconnecting member secu're'd at its'ends' to the upper terminals of theend members, a lower horizontal connectlng and, support ing member secured jat'its terminals to the U inclined end members and supported intercenter by theinner arms of the levers, and
lower connecting members.-
