I Patented 21, 1930 UNITED STA res JOHN GREEN, OAKLAND, CALIFORNIA FRAME consraucrron Application. filed May 14,

My invention relates to improvements in frame constructions, particularly useful in the erection of the structures commonly known as steel buildings, although also useful for other purposes, including the buildtion andthereby effecting a substantial saving in labor cost, but also eliminating the noises made by the workmen in securing the rivets (which noises have lately been found decidedly objectionable particularly in the larger cities throughout the country), as well as materially shortening the time during which portions of the adjacent side-walls and streets must-be set aside for the use'of the contractor erecting the building.

With the foregoing and other objects and purposes in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawings in detail, throughout which like reference characters designate like parts:

1 'The numerals 1 and 2 designate the vertically extending columns and horizontally extending girders, respectively, of the present invention. j

The columns, which are preferably formed of structional steel either of the usual I-beam or 2-piece channel-steel stock, have their .lower ends disposed upon and secured, in any preferred manner, to a suitable foundation 3, formed preferably of concrete.

In the event that any of the columns 1 are found to be too short for the purpose intended, they maybe extended to any suitable length by disposing two or more together endto-end, in which position the two registering ends are maintained in fixed longitudinal alignment by means of a rectangular. annular binding sleeve 4 fitted snugly around against the two abutting end portions of the columns,

extending about equidistant from the abut-' ting end of each (see Figs. 1 and 3).

Intermediate the ends of the columns 1 are rigidly secured supporting brackets 5. These supporting brackets, which comprise, each, a vertical member 5, preferably riveted. or welded to the sides of the columns 1, and a horizontally extending member 5 projecting at right angles outwardly from the upper end of said vertical member. In the present illustrated form of the invention the supporting brackets 5 are secured by means of rivets 6, which pass through both the lower members 5 of the brackets and the body portions of the-columns 1.

' Encircling the column limmediately above the bracket 5, and preferably seating on the latter, is a rectangular annular securing band 7,. which is adapted to fit snugly, butnormally operatively slidably, against the sides of the column, excepting, however, the side of the column against which is secured the supporting bracket 5. On this side itris spaced 2. suitable distance outwardly fromt e column to form a slot 7 the function of which will become apparent as the description proceeds. v

Longitudinally across the length of the girders 2, are secured securing plates 8 by means of rivets 9. These securing plates are somewhat longer than the girders to which they are secured, to permit their ends being struck at right angles downwardly to form locking lips 10, which are spaced suitable distances outwardly from the squared ends of the girders, to form interlocking niches 10 between the ends of the girders and said locking lips.

The ends of the girders 2 are disposed on their respective brackets, previously attached to the columns, and are permanently secured to said columns by slipping the locking lips 10 down into their'respective slots 7 a as far as they can go, and disposing the adjacent sides of the securing bands 7 in the niches 10 The dimensions of the interassociating parts of the locking lips 10, securing bands 7, relative to the slots 7 a and niches 10*, should be such that when these parts are disposed in their proper positions for permanently bindin the girders to the columns, the girders wi I bear firmly on their respective supporting brackets 5, and there will besubstantially no longitudinal movement of the girders relative to the columns.

The'securing plates9 are referably secured to the girders 2, and the supporting brackets ,5 to the columns 1, 'at the shops or mills where the steel isprepared and before the same is delivered to the premises where the frame is to be erected. a

Where two or more girders are disposed in the same horizontal plane and have ends attached to the same column but on different sides thereof, obviously, there must be secured a'supporting bracket 5 for each girder, and the securing band 7 will have to be made large enough relative to the transverse dimensions of the column to allow suflicient room between the latter and said band to permit the'entrance therebetween of the locking lips 10 of each girder (see Figs. 5, 6 and 12). In the event of two or more girders being secured to .the same column, as above stated, it will be found that thiswill result in rectangular vertical extending openings 11 being formed at the inner corners of the supporting bands at the intersections of the adjacent edges of the locking lips of each pair of girders disposed at relative right angles.

These openings are preferably filled by driving closely fitted locking pins 12 thereinto (see Fig. 12).

The columns 1 may comprise a single length of steel, or, if preferred, as would likely be the case in the erection of tall structures, two

or more columns may be butted together end-to-end, and held in longitudinal alignment by encircling the connected end portions of each pair of abutting columns with an annular rectangular sleeve 4. If said pairs of abutting columns are of unequal transverse dimensions, as would bethe case if a smaller column was set on top of a larger one, the sleeve 4 should be made with unequal lnterior dimensions corresponding with the different dimensions of the columns, so as to fit snuglyagainst the sides of each.

Having described my invention, what I claim and desire to secure by Letters Patent, is: I

1. In a frame construction of the character between the outer face ofthe column and the inner face of the band.

2. In a frame construction of the character described, the combination with a vertically extending column having a supporting bracket secured to and extending laterally outwardbeyond one side thereof, of a girder having an end portion bearing on and supported by said bracket, a lip carried by said girder, a band slidably encircling said column and embracing said lip.

3. In a frame construction of the character described, the combination with a vertically extending column, of a locking band encircling said column, a horizontally extending girder, a locking lip at one end of said girder extending across the end thereof in spaced relation thereto and disposed between a portion of said band and said column, and means carried by the column for supporting the girder.

described, the combination with a column 4. In a frame construction of the character set forth, the combination with a vertically extending column having a su porting bracket on one side, of a securing and encircling said column above said bracket, 8. horizontally extending girder having one end portion resting upon and supported by said bracket, a securing plate fixedly secured to said girderand having a locking lip overhangmg one end of said girder and in spaced relation thereto, said locking band having a portion disposed between said locking ip and girder whereby one end of said girder 1s I held substantially in fixed relation to said column.

5. In a frame construction of the character set forth, a horizontally extending girder, and a securing plate extending longitudinally of said girder and fixedly secured to the upper side thereof, a free end portion of said plate extending downwardly across and in spaced'relation to an end of the girder to form a locking lip adapted to interlock and cooperate with means carried by a column to secure the girder to the column.

6. In a frame construction of the character described, a column, a supporting bracket secured to said column, a girder restin at one end upon said bracket, a lip carrie by said girder, and a band encircling the column and embracing said lip, all portions of said girder being isposed intermediate the ends of the column.

In testimony of the foregoing being my own, I have hereunto atfixed my signature this 30th day of April, 1929.

JOHN GREEN.
