POST-CAP.
SPECIFICATION forming part of Letters Patent No. 760,512, dated May 24, 1904.
Application led January 30, 1904. Serial No. 191,298. v(No model.)
To ttl whom, it may concern.-
Be it known that I, ALFRED S. ALscHULER, a citizen of the United States, residing' at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Post-Caps, of which the following is a full, clear, concise, and exact description.
My invention relates to building construction, and more particularly to a post-cap or connection for supporting girders and joists where they abut against vertical posts.
I will describe in detail certain preferred embodiments of my invention by reference to the accompanying drawings, and the parts, improvements, and combinations which I consider to be novel will be pointed out in the appended claims.
In the drawings, Figure 1 is a side view of a post and girder connection with a post-cap of my improved design. Fig. 2 is a transverse sectional view of the post-cap, the posts and girders being indicated by dotted-lines. Fig. 3 is a perspective view of my improved postcap, the posts and g'irders being shownl in dotted lines. Fig. 4: is a side view of a post, girder, and joist connection with a four-way post-cap of my improved design, which is adapted to support the joists so -that their upper edges will come in the same plane with the upper edges of the girders. Fig. 5 is a transverse sectional view of the four-Way post-cap, the posts, girders, and joists being indicated in dotted lines. Fig. 6 is a perspective view of the four-way posteeap with the posts, girders, and joists indicated in dotted lines. Fig. 7 is a detail perspective view showing how the cross-pieces which support the joists may conveniently be formed.
The same letters of reference are used to designate the same parts wherever they are shown.
Referring iirst to the post and girder connection shown in Figs.l l to 3, inclusive, the post-cap consists, essentially, of an inverted steel channel-plate having its horizontal web a adapted to rest upon the top of the lower post b and downwardly-projecting flanges a adapted to `embrace the sides. The ends of `the cap-plate a project beyond the sides of the posts, and I provide end pieces c, of anglesteel of L-shaped cross-section, which lie across the projecting ends of said cap-plate. The vertical flanges c c of the angle-bars are adapted to lie against the sides of the upper post to prevent the lateral displacement of said upper post, which is seated upon the plate a of the post-cap. the end pieces c c extend outwardly and rest upon the projecting ends of the cap-plate a and may be bolted or riveted thereto. The angle-steel end pieces c c are adapted to receive and support the abutting ends of the girders e c, the lower corners of which girders rest in the seats formed by said end pieces. Crossribs f j' are preferably provided in connection with said end pieces for the purpose of serving as anchors for` the girders, said ribs being adapted to lit into notches in the lower edges of the girders. I prefer to form these ribs by turning up the eXtreme ends of the cap-plate a just beyond the edges of the horizontal flanges 02 of the angle-pieces c, as this is a cheap and convenient construction. It is evident, however, that these cross-ribs may be formed of separate pieces riveted onto the flanges c2, if desired. The body portion of the cap-plate, as I have heretofore pointed out, is preferably made of a section of channel-steel; but it is evident that it might be made of a bent plate, or instead of the vertical 'flanges being formed integrally with the central plate these parts might be separate pieces suitably united.
I will now proceed to describe the four-way post-cap or connection by which the ends of the joists g g, abutting' against the post, may be supported, as well as the gil-ders e e, by the post-cap. A four-way post-cap may easily be made upon the same principle as the two-way post-cap by extending the angle-bars or end pieces c c on each side beyond the sides of the post and uniting these projecting ends of the angle-bars by cross-pieces /t l1., which will form ledges adapted to receive and support the ends of the joists g g. The cross-pieces /L L are preferably made of angle-steel, having the vertical flanges resting against the post The horizontal ilanges c2 of and the horizontal iianges forming ledges or shelves upon which the lower edges of the joists may rest. The cross-pieces may be supported by the projecting ends of the anglebars c c in any suitable way; but I prefer to form these cross-pieces, as shown in Fig. 7, of a section of angle-steel, having the eX- tremities of the horizontal flange turned down in position to lie against and be riveted to the projecting vertical fianges of the angle-bars c c. It is evident, however, that cross-pieces of other forms may be employed and that these may be supported in various ways upon the projecting end pieces o c.
The post-cap of my invention is especially advantageous in that it is light, strong, and easily and cheaply constructed, requiring but few parts and these of simple forms, which are easily and quickly assembled.
Havingthus described my invention, I claim as new, and desire to secure by Letters Patent, the following:
l. A post-cap comprising a metal cap-plate a, adapted to lie upon the top of the post, downwardly-projecting anges a a at the sides of said plate adapted to embrace the sides of the post, the ends of the cap-plate projecting on either side beyond the line of the post, angle-bars oi L-shaped cross-section having horizontal flanges turned away from the post, said anges lying across the projecting ends of the cap-plate and being fastened thereto, the vertical flanges of said angle-bars being adapted to lie against the sides of the upper post, said L-shaped angle-bars being adapted to receive and support the lower corners of abutting girders, substantially as set forth.
2. A post-cap comprising a metal cap-plate having horizontal anges lying across the pro- 1 jectirir ends of the cap-plate and being fastened thereto, the vertical flanges of said angle-bars being adapted to lie against the sides of the upper post, said L-shaped angle-bars being adapted to receive and supportthe lower corners of abutting girders, and cross-ribs f f formed by the upturned ends of the capplate beyond the horizontal flanges of said angle-bars, said ribs being adapted to serve as anchors for said girders.
3. A four-way cap-plate comprising a capplate a and downwardly-projecting flanges a adapted to fit over the top and against the sides respectively of a post, the ends of said plate projecting beyond the sides of the post, angle-bars of L-shaped cross-section, having horizontal flanges lying across the projecting ends of the cap plate and fastened thereto, the ends of said bars projecting beyond the sides of the cap-plate, said angle-bars being adapted to receive and support the ends of girders, and cross-pieces uniting the projecting ends of said angle-bars and supported thereby, said cross pieces Jforming ledges adapted to support the ends of joists, substantially as described.
In witness whereof I hereunto subscribe my naine this 27 th day of January, A. D. 1904.
