POST-CAD.

YApplicanam 1aed March 2s, i920.' serial No. 368,917.

Be it known that l, Sinner L. DRYroos, a citizen oi the TJnited States' of America, residing at Cleveland, inV the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Post-Caps, of which the following is a specitication. Y A

My Vinif'entioii relates to improvements iii` post caps ol' the type adapted to be constructed of steel plate and has for its Object the provision of a post cap which affords a greater initial and ultimate strength than is secured by any other like structure of the saine weight and'cos't Ot manufacture.

Another object orn my invention is the avoidance of the expense for labor and the delay in preparing the end of the supporting post, which necessarily is involved by the use or" the well known and commonly used sheet metal post cap of the prior art, disclosed in the patent to' Tuteur, No. 761,020, May 24th, iaei.

Referring to the structure therein set forth. it is seen that the post cap comprises two flat side plates united by lateral .bolts with an inverted Ll-shaped bearingplate.

liese bolts alone are depended upon in use, for transmitting the strain to the s ideA plates and said bolts, accordingly, are subjected to extreme shearing action. Moreover, the

vdepending legs of the U-shaped bearing dependently ot the connecting. bolts orV rivets, while the depending' side portions of said supporting plate are disposed iii re cesses formed in the side plates, so that they are flush with the major portions of the respective side vplates, andshaping or trimming of the supporting post is com-k pletely eliminated.

rl`he structural features of the post capV embodying my invention and its further ad* vantages may be best explained by making Specification of Letters Patent.

Patented reference to the accompanying drawings,'

wherein:

Figure l is a view ink elevation showing a post cap of my invention with the supported girders and upper and lower posts in'position, but adjacently broken away.

Fig. 2 is avertical section on line 2 2 ofV Fig. l.

Fig. 3 and Fig. 5 respectively illustrate in perspective, the disassembled side plates,

while Fig. 4 similarly shows the associated supporting plate therefor.

Fig. 6 is a perspective view cut in vertical section illustrating the employment of my improved post cap.

` Throughout the several igures of the drawings I have employed the same charaoter of reference to indicate similar parts, but it should .be noted that `for purposes 'of illustration, the cross section of the sheet rmetal has been somewhat exaggerated asv compared with the requirements of ordi-v nary practice.

' The several members of thefpost cap are shown in Figs. 3, 4 and`5, comprising twol side plates a, I), and an 'intermediate bearing member or supporting plate c' of substantially U-shape, which isl adapted to fit within the recesses of the side plates and .receive support along its depending edges throughout the lengths of the shoulders a, o. Theseside rplates are readily out', shaped and punched from steelplate, Vwhile the bearing member 4may be similarly formed or it may be fabricated from suitable structural shapes or channel members.

A plurality Ot transverse bolts Z serve to connect the members of the post cap in the well known manner, but with the depending legs of the channel or Ushaped bearing plate irmly clamped within the recessed side portions intermediately of the side plates. It will be very readily understood that with the upper and lower posts j, c, inserted within the post cap, wherein they accurately fit., this bearing plate is substantially reinforced by the side plates lthroughout their respective length, so that the bolts are relieved from excessive strain of the weight carried upon girders g, 71,. In consequence, the post cap of my invention may be made of less length than that of the prior art, and still afford equal support oct. 12,519.20.

for

supporting post'e is' apparent. VThis involves unnecessary expense for laborV and an appreciable reduction in the cross section, of the uper end of said post. Thus, in erecting'the building, theposts c, f may be in-V serted'in placewithout framing, and'held in their assembled relation `by lag screwsz', before placing said posts 1n position within' the structure. This materially advances v building operations, with a reduction in the cost of labor, when my improved postcap is used. Y Y

It will be appreciated that practically the same advantages are present inthe use of this post cap in inverted relation, .e., with the legs of the U-Shaped bearing member positioned above the level of saidv plate, and

Ihave employed Vthe terms herein and in the appended claims K relatively, vmerely .as

l.cap of my invention, I claim as new and" desire tosecure Vby Letters Patent, the' fol-. lowing:

descriptive of thepreferred position-i ofthe post cap. f

In order to ing member, .I may also insertv rivets ,jjto

gsupplement the bolts d; these serving to clamp thev depending edges yof the bearing member securely within thesupporting recesses, preferably adjacent to theY eXtreini# ties thereof.V Under ordinary lconditions I however, a plurality ofbolts. which insureV more vready assemblage of the post cap, are all that are required for connecting the respective members thereof.

Having now described the improved post l, A'post capconstru'cted vfrom steel plate, comprising a U-shaped bearing member, two

steel side plates respectively offset inter mediately to accommodate the lateral portions of ,said bearingmember and afford thetimbers and the load carried there- Y With the cited post cap ofthe priorart" the necessity for framing and fitting the afford additional initial sup` port for the engaging edges of the bear-l support therefor, and means for uniting said `side plates and bearing membeig substan-V tially as set forth. y V f K 2.
