JAMES EDGAR Moon'ir,
' cnu'runms-uonn.
3e it known that I Janus 'E; Moonr, a i citizen of the United tates, residing at Essex, in the county of Kankakee and State of Illinois have invented a new and useful Centermgold, of which the following is especi- This invention relates to building .con-. struction and more articularly to .a hanger or centering device or so porting the temporary floorin or arched fi'ames used in the constr'u'ction o bridges, floors, ceilings, roofs, side walks, viaducts, .and other masonry structures. 7 Y
The object of the invention is to provide a centering device orhanger capable of being readily attached to the su porting joists of a building and by means 0 which the temporary flooring or arched frames may be sus. pended from and retained in position on said oists during placement of the concrete or other materla a A further object is to provide a hanger including a center bolt hav ng a flanged retain-T ing plate loosely mounted on one end thereof for engagement with the work and provided at its opposite end with a clampin member for en agement with the adjacent loor joist, there elng a sleeve interposed between the clamping member and nut for adjusting the thereby to regulate the thickness or depth of the concrete CQVGI'XDI or floor.
generally to improve this class of devices so as to increase their utility, durability and Further objects and advantages will apear in the fol owing description, it being unerstood that various changes in form, proportions and minor details of construction may be resorted to withinthe scope of the ap ended claims.
n the accompanying drawings forming a part of the spec1fication:Figure 1 is a perspective view of a portion of a floor showing my improved centering device or hanger in position thereon. Fig. 2 is a detail perspective view of one end of one of the'temporary floor supporting bars showing the manner of fastening the hen er thereon.

OF ESSEX, ILLINQJS." p
Similar numerals of reference indicate cor-- ll'etented Aug-3, 1900;
responding parts in all of Phelfigures of the drawings.
The improved centering device forming the subject matter of the presentinvention is principally designed for use in the construction 0 concrete'floors, ceilings, viaducts' and other masonry structures and by way of illustration is shovm applied to the support-- ing joists of a floor in which. 5-design'ates the joists-preferably in the form of eye-beams,
although any other styleof joists may be used if desired.
Interposed between the joists 5 are one or moretransverse bars 6 ada ted to receive and support the t mporary ooring 7. The bars 6 are preferai ly .formed of longitudinal strips spaced apart by one or more filling t-locks 8, the terminalfilling ll-ocks being spaced inwardly from the opposite ends of t e bars 6 to form recesses 9 adapted toreceive the adjacent ends of the, center bolts orhangers 10. The lower end bf each hahgeris provided with asquared head ll'andgsm cured to or formed integral with saidhead is a squared shoulder 12 which sitters a correspondingly'shaped recess 13 formed in.;.-a work-engaging plate 14. r The ork-enga-1gmg plate 14 is preferably formedfof a fiat piece of metal having its opposite ends deflected laterally to form inclined flanges 15 adapted to ltear against the auljucent lou itudinal edges of the strips constituting the lars 6. Attention is here called to the fact that the opening 13.'is slightly larger than the cross sectional diameter of the squared portion or shoulder 11 in order to allow for slight tilting of the plate 14 and thus adapt the device to any irregularities or unevenness in the timbers comprisin the lars' 6. This slight tiltin movement 0 the plate,- 14 also insures equa distril ution ofJthe wei'iht on said plates. The. opposite end oifl't'he bolt or hanger l0'is threaded at lfijijli'oij'en ga ement with a l;ur or nut 17. g r iii??? oosely mounted forslidingf ni p if ehgient on the unthreaded portion of thelriiltllihs a clamping plate 18 having one end thereof provided with a plurality of o enings 19 to permit the (passage of the hot 10 and its oppositeen bent to form an over-hanging hook 20 adapted to engage and clamp the up er flange of the adjacent beam 5.
nterposed between the upper surface of the clamping plate 18 and the nut 17 is a loose sleeve or collar 21 which, when the adjacent'nut is tightened bears against the clamping member 18 and serves to lock the latter in position on the adjacent eye-beam or joist. Thus it will be seenthat by rotat -e ers and also serve to'limit' the lateral inovearent of the bars 6;
In constructing a floor, pavement or the like the hangers '10 are extended through the recesses-9 of the bars 6 with the retainifi plates '14 in engagement with the lower 6 cs plates 18 epgaging the upper fianges o I the eye-beams or floor-'oists 5, fter which the nutsil? are ad'uste so as to, ear against the sleeves 21 an thus lock thei several parts in position on the joist, in the manner before described. After the parts are thus positio ned a temporary flooring'is supported on the bars 6 andthe' concrete,=cement, asphalt or other material shoveled or otherwise.
placed'op the temporaryfiooring and levsled-0H m the usual mann r. In order to remove the floor it is me 1y necessar to detach the, nuts when thetemporary oori'ng may be lowered between t e floor supporting joists without dangleir of chipping or otherwise marring -or crac n'g the cement or concrete flooring. 7
Attention is here called to the fact that the several hangers are independent and detachabl? an floor sup orting joist's 5 so that said hangers may independently ad usted to .permit alinin of the temporary flooring and .lalso" ito permit independent detachment of 46?; aid-hangers.
r Fig. 4 of the drawings the device is {shown used for constructing a flooring hav timber 25 forms a supp longitudinal ed 'i'ng itslower face arched.'- In this form of the 51s ittcnded arallel with rd or p ank 24 rests ngisudinsl edges of the and'forms a" support for the frames hus. it will be seen that the plank or ort for the. adjacent es of the arch frames on opslte. sides of t e eye-beams or joists;
. When the hangers are employed for supporting arch frames the clamping plates 18 of said bars and with the clam ing connected with the transverse beams 6- senses with the retaining plates, in the manner bev fore described.
In some cases suitable standards or supports 26 may be employed for reinforcin and bracing the temporary flooring or arched :frames inorder to' assist in sustaining the weight of concrete or other plastic material. If ,esired, however, these 'bars or standards may be dispensed w'th, and in which event, the bars 6 and 6 be made stro er and more of said bars employed for spanning the ap between the adjacent floor 'oists.
is claims is:- l 1. In masonry construction, the combination with the floor joists, of supporting bars adapted to receive a temporary flooring, hangers extendin throughthe su porting bars and having t eir upper ends tii clamping plates having hooked terminals for en agement with the ad'acent joists, and provi e with openings a apted to receivelthe hangers sleeves s idably mounted on the threaded portions of the hangers and ads ted to bear against the u per faces of't e platesfland nuts engaging t e thre'ads'on said angers for clam ing the sleeves in engagement with said ates.
2. A hanger or masonry construction includin a bar having one end thereof threaded and its opposite end provided with a squared shoulder terminating in an enlarged head; a; retaining plate loosely mounted on the hair at said squared shoulder and provided w th op csitely disposed work-engaging H n s, a 0 am ing plate slidably' mounted 0 ti e bar and mid ings o rmed in one en thereof and having its opposite end bent u on itself to. form an over-hanging clamping 00k, a sleeve loosely mounted on the bar and forming a housing for the threads, and a clamping nut engaging said threads for forcing the sleeves in engagement with the cla'mpin late.
