POST-CAP. v

SPECIFICATION forming part vof `Letters.Patent No. 725,527, `dated. .April 14,1903. y rApplication filed J'anuaryS, 1903.y Serial No. 137,649. (No model I To all whom it mag/concern?, I

Be. it Yknown that I, ROBERT W. WHITE- HURST, a citizen of the United States, residing at Norfolk, in the countyof Norfolk and State,

of Virginia, have invented certain new and useful Improvements in Post-Caps, of which Vthe following is a specification.- f

This invention'relates to improvements in post-caps which are designed foruse in buildings to support one post vertically above another and to. support also the girders. b

The object of the invention is to provide an improved post-cap of this character which will so support the post above it and also the grders as to allow the latter to fall out in j case'of a fire or from any other cause Withtions,arrangements,and combination of parts,

out danger `of tearing down the posts and which will tend to protectthe posts from` catching fire from burning-vgirders.

The Invention consists of certainconstruchereinafter fully described and claimed, refer- `encebeing had to the accompanying drawin gs,

in whichen y Figure 1 is a perspective cal sectionalview thereof in applied position.

' Fig. 3 is a top plan view of thepost-cap with the top plate removed. Fig.` 4 lis, a bottom plan view of said top plate.

top plate for said modified form o'f post-cap.,l

The post-cap illustrated in Figs. l to 4, in-

A elusive, comprises a base-plate a, provided on its under side with a socket b, adapted to` y iitover the upper` end of thelowerpost'c.`

It also comprises two vertical side walls d, rising from said base-plate and provided in their upper edges with V-shaped grooves or nicks e, and a central vertical web or partition f, extending from thebase-plate to the i upper edges of the side wallsjand from one side wall to the other, A,thereby dividing' the post-cap into two entirely separate compartments g for the reception of the `ends of the girders h, and said webalso provided in i-ts vupper edges `with V-shaped nicks fi, and a top plate jis supported on the upper edges of said web and sideV walls, said top plate beview ofone form of the improved post-cap. Fig. 2 is a verti- Fig. 5 is a perl' spective view of a modified form of post-cap.

ing provided onfits under side with rvlugs" lc, fit-v ting in the nicks e and t tohold Vit secure and prevent'it from skewing, and provided in its upper side `with. a socket or depressiony Z, in `which is seated the lower end of the upper ostjc'. The accom an in@ drawings illusp p b D `trate the base-plate, tw'o side walls, and cen'- l tral web or partition, all cast or formed inione integral stru cturefbut said parts may also bev madel separable 'and secured together, although the integral structure is preferable.

' Two studs m project from the upper surface of the base-plate a ou opposite sides of the web f, and each .girder isprovided with'a socketn, which 4receivesone ofthe said studs, so as to securethe girder in Aplaceand prevent any longitudinal movement of the same. The end of each girder is beveled on top, as indicated at o, Fig; 2.

From the foregoing'description of the parts itis evident; rst, that withthe improved constructionv off=post'cap th'e'weight of the gird-v ers is supported directly over the post which is below their ends and not upon any base.

plate iianges which project beyond said post;

second, that in case the girders. should fall or break down by reason of fire or anyother `cause the beveled ends ofthe girders will allow the llatter to tilt'outwardly from the post without tearing the latter down,v and, third, that the upper rpost c' is supported entirely free from 'contact' with the girders, thereby minimizing the vdanger of its catching re from al burning gi-rder. AThese advantages are also present in the modified form of post.

"cap illustrated in Figs. 5 lto 8, inclusive. U b s The-main'difference,betweenthe post-cap before described .and the modified post-cap ers and the latter being formed to support four girders'or may support only three girdf ers, if preferred. The webf,therefore, of thek modification is cruciform, as best seen in 'now to be described are dierences of form, y the former being formed to support two gird- Fig. 6, and is disposed diagonally with re-v spect to the postsockept b' on the 4under side of the base-plate a', as indicated in Fig. 7, whereby toform V-shaped compartments g' for the reception of" the ends of the girders, and in each compartment is a stud m', similar to the stud m of the other 'construction of post-cap. Thev lupper edge of the web f IOO is provided with V-shaped nicks t", which, as shown in Fig. 6, are disposed obliquely therein, and the top platej' is provided on its under side with corresponding lugs 7o to enter said nicks and retain the top plate in proper position and prevent it from skew/ing. The top plete is also providedwith a socket or depression Z to receive the lower end of the upper post. The girders (not shown) intended to be supported by this modified form of post-cap must have V-shaped ends to correspond to the like shape of the compfirtments g@ in which they are received.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A post cap, comprisingT a base plete adapted to be secured to the upper end of a post; s vertical web supported by said baseplate and producing compartments for the reception of the ends of girders or the like, sind said web provided in its upper edge with nicks; and a, top plate supported on said web and adapted to be secured to the lower end of a post and provided on its under side with lugs taking in said nicks.

2. A post czrp, comprising,r :t base plate adapted to be secured to the upper end of a post; a Vertical Web supported bysuid baseplate and producing compartments for the reception of the ends of girders or the like, and said web provided in its upper edge with nicks; a top plate supported on said web and adapted to be secured to the lower end of a post and provided on its under side with lugs taking in said nicks; and a stud on the base-plate in eachcompartment adapted to be engaged by the ends of girders or the like,

as and for the purpose set forth. i

In testimony whereof I aiix my signature in the presence of two Witnesses.
