UNITED PATENT @Flflfilhh JOHN S. GOURLAY, OF SYRACUSE, NEW YORK.
BEAl /I-TRUSS T 0 all whom it may concern:
Be it known that 1, JOHN S. GoURLAY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and. useful Improvements in Beam-Trusses, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to certain improvements in beam trusses and refers more particularly to the means for anchoring the ends of the truss rod.
The object is to anchor the tie rod to the beam with a minimum number of bolts pass ing through the beam thereby avoiding excessive weakening of the beam by bolt openings and at the same time reducing the cost of such anchorage.
Other objects and uses will be brought out in the following description.
In the drawings l igure 1 is an elevation of a portion of a beam showing a truss rod and my improved anchorage connecting its ends to the beam. Fig. 2 is an enlarged elevation partly in section of a beam and one of the anchorages for the truss rod. Fig. 3 is an inverted plan of the anchorage seen in Fig. 2.
A- represents a beam of any size, length or material and B is a truss rod having its central portion held a fixed distance from the under side of the beam by a suitable stay or brace 1 which in this instance is secured to the under side of the beam by suitable fastening means as bolts 2-. The opposite ends of the tie rod -B- are extended equi-distant from opposite sides of the stay 1- and are secured to suitable ancsior plates 3 which in turn are secured at one end by bolts a to the under side of the beam. These anchor plates are substantially identical and it will be necessary to describe only one of them which consists of a cast metal having apendent transverse rib 4 substantially midway between the opposite ends of the main body, the latter being substantially flat and provided with an upwardly projecting transverse rib -5- also substantially midway between its ends and in alinement with the pendent rib 4. The main body -3 therefore, extends longitudinally some distance beyond the plane of the ribs l and 5-, the rib --4- being reinforced with the inner portion of the plate 3 by a brace 6 formed integral therewith, the outer end of Specification of Letters Patent.
Application filed September 17, 1908.

Serial No. 453,483.
the plate --3 being provided with apertures 7* alined with similar apertures in the beam A- for receiving the bolts -a, of which there are in this instance two. These are the only bolts by which the plate -3 is fastened to the beam and are whjpllyat the outer ends of the truss rod The ribs 4 and -5 and greater portion of the plate 3* are wholly inside of the bolts a, the rib 5 being seated in a corresponding recess -8 in the under side of the beam at the inner side of the bolt a so that the sides of the recess -8 form abutments to resist longitudinal movement of the anchor plate 3 relatively to the beam thereby relieving the strain upon the bolts a.
The pendent rib 4 is disposed at substantially right angles to the adjacent end of the truss rod B and is provided with an aperture -9 for receiving the adjacent threaded end of said rod which is engaged by a nut 10* abutting against the outer face of the rib 4 to firmly tie this end of the rod to the anchor plate 3.
It will be seen upon reference to Figs. 1 and 2 that the anchor plate 3 has a bear ing against the under side of the beam some distance inwardly from the ribs 4* and 5 which takes a great portion of the strain incidental to the tightening of the truss rod underload on the beam -A and tends to produce an uplift toward the center of the rib to resist such load and at the same time the rib -5 on the upper face of the plate abutting against the inner side of the recess -8- takes a great portion of the strain off the bolts thereby preventing any possibility of shearing strains upon the bolts. The main feature of the invention, therefore, lies in the particular construction and arrangement of the clamping plates 3, that is in extending said clamping plates a considerable distance from the bolts by which it is secured to the beam and providing the upper face of said plate with a transverse rib which is seated in a recess in the under side of a beam, which in connection with the attachment of the end of the truss rod to the pendent rib *4 tends to relieve the strain upon the bolts -a and at the same time the load upon the beam which is transmitted to the truss bar tends to force the inner end of the plate upwardly against the under side of the beam thereby affording a considerable resistance to the bending of the beam under the truss rod, and the other rib being re- 10 load. cessed into the beam.
