' Specification of Letters Patent. I

Patented Sept. l'', 190'?.

Application iiled April 20, 1.907. Serial No. 369,257.

To all 'whom it may concern:

Be it known that I, HUGO ,I-IAISS, a subject oi the Emperor of Germany, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and usefull Improvements in Universal Beam-Frames, of which the following is a specification, reference being had therein to the accompanying drawing.

' This invention relates to universal beam irames, and the invention has for its object to provide a novel skeleton frame for concrete beams and girders to add rigidity to them as well as to prevent sagging and cracking thereof. i j

` My invention aims to provide a metallic frame adapted to be embedded in concrete beams or girders, the frames being constructed to equally distribute in the beam the stresses and strains exerted thereon, thus preventing shear stresses at the edges of; the supports. To

this end, I have devised a metallic skeleton trarne wherein a series of bars or rods are arranged, locked together and anchored infa beam or girder. The seriesA oi bars can be arranged in sets or be duplicated according to the load of a beam or girder and as Well as its span or stretch. In some instances, Where the shear stresses are excessive, I use stirrups and stirrup spacing bars inconnection with the beam irarne, the stirrups being assembled in closer proximity to one another at the ends of the beam, thereby preventing dislocation of the beam or girder due to shear stresses` As a reinforcement Vfor beams and girders, the universal frame provides an anchorage to preventslipping of the bars embedded in the concrete, the reinforcement sustaining the entire weight of the beam or girder, thusproviding a beam or girder of considerable strength and rigidity and tree from all danger of being dislocated by vibratory or constant load stresses.

The detail construction entering into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims.

Referring to thedrawing forming part of this specification, like numerals of reference designate corresponding parte throughout the several views, in which:-

Figure l is a perspective view oi one end oi a beam frame or metallic reinforcement constructed in accordance with my invention, with stirrups as attached to the same, 2 is a plan oi a clip used for securing the -stirrups to the stirrup spacing bars, Fig. 3 is a perspective view oi the stirrups removed from a frame, the stirrups in this instance being constructed of round bars, Fig. i is a similar view illustrating the stirrups formed from hoop-iron, Fig. 5 is a plan of a clip used in connection With the form oi stirrups shown in Fig. 4,

i Fig. t` is a perspective view of a beam frame, illustratinga simplified form consisting of a single layer oi bars for rods, Fig. 7 is a perspective vienr o one end oi a Kreme cnstmctedwith a double 'layer oi oars or rode,

Fig. 8 is an end view oi the irame loch 'used in connection with the frame illustrated in Fig. t3 of the drawings, Fig. 9 is a similar view oi a frame lockV used in connection with the frame illustrated in Fig. 7, Fig. I0 is a iront elevation oi a double trame lock embedded yin a beam or'girder, Fig. .ll is an inverted plan oi the same Without the embedding concrete. Fig. l2 is a side elevation, Fig. I3 is a perspective view oi the double frame lock, Fig. I4 is a plan ot a frame lock illustrating twisted bars secured therein, Fig. l5 is an elevation oi' the same embedded in a concrete beamv or girder, Fig. l6`is a side elevation of the same.

To put my invention into practice, I construct my improved beam or girder frame o a plurality of parallel. rods or bars' l arranged in a horizontal plane and maintained in this position parallel with one another by singleirarne locks 2 and 3, said locks comprising bars through which the rods or bars l. extend. Theframe locks 2 and 3 are provided with depending supporting plugs 4 and with laterally projecting separating plugs term as the end housings of a beam frame, while the o. Thetrame locks 2 constitute what I Willthereinafter locks 3 constitute intermediate housings, which are A' preferably located in close proximity to the end housings on account oi the ends oi the concrete beam or girder being subjected to shearing stresses. lt will therefore be observed that considerable space may exist between the intermediate housings at one end or' a beam and the intermediate housings at the Opposite end, the amount oi space entirely depending upon the length and span oi the beam. `Thelocks 2 and 3 and the rods or bars l iorm practically the foundation of ,a concrete beam or girder, and in ordery that the ends oi the rods or bars l can be 'firmly anchorgd in the plastic composition. oi the beam or girder, I provide the ends oi the bars or rods l withheads 16, which will also prevent slipping of said bars in the concrete.

Upon the locks 3 oi the intermediate housings are secured by bolts and nuts 7,locks 8 and 9, thelock 8 housing rods or bars l0, While thelock 9 houses the rods or bars l0 and rods or bars Il, thus forming two layers of lrods`or bars between the intermediate housings.

For supporting the ends of the vrods or bars l0 and Il, I provide thelocks 2 of: the end housings with rectangular shaped brackets l2, upon which ore iastened by nuts andbolts 14, locks l5, said locks receiving the upwardly bent ends oi the rods and bars l() and 1I, the ends after passing through the locks l5 being parallel with the rods or bars I and provided with heads I6. In elevating and anchoring the ends of the rods or bars l0 and Il inf-the manner just described, there is less liability ofthe centralportion oi the beam frame sag 'fing cr deiccting -than would be the case ii the ends ci the rods orbars 10 and Il remain parallel' escaso lboth iayers and supporting the bent ends of the rods or 4mansversely-extending housings each embraeing ail of the rods or bars of lboth iayers, transversely-extending housings each embracing all of the rods or bars of the lower layer and some of the rods orbarsof the upper layer, the rods of the upper layer having the ends thereof bent in an angular manner with respect to the remaining portions of the rods, transverseyextending housings embracing the ends oi' the rods or bars of both layers-and supporting.l the' angular ends of the rods or bars of the 'upper layer in un eievated position with relation to theiower layer, said rods 'or bars having anchor ends.
