f HEINFORCING DEVICE FOR CONCRETE STRUCTURES.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed March 17,1905. Serial No. 250,571.

:was iireprooi structures or buildings, and ,particularly buildings ot this class whichv einplcv columns, beams, girders, and the like composed oi concrete reinforced with steel bars, ties, or other devices oi various kinds and classes which are embedded in the concrete material; and the object of the iiivention is to provide an improved reinforcing or strengthening device for use in structures of the class speciiied4 and which-may be einployed in columns, beams, and girders coinposedof concrete or similar material and which may also be employed in Vfloor an d ceiling construction or in making slabs or -plates of any size.

The invention is fully disclosed in the following specification, of which the accompanying vdrawings form a part, in which the separater-parts of my improvement are designated by'suitable reference characters in each of the views, and in which- Figure 1 is a side view of a reinforcing device of the class speciiied made according to my invention, parts being sectioned; Fig. 2, a section on the line 2 2 of Fig. 1 Fig. 3, a view similar to Fig. l, but showing a mod iiication; Fig. 4, a section on the line 4 4 of Fig. 3; Fig. 5', a view similar to Fig. l, but showing another modification; and Fig. 6, a section on the line 6 6 of Fig. .5.

in the practice of' my'invention as shown in Figs. 1 and 2 rovide two parallel bars c and the bar a in t ie form of construction shown being composed oi" channel-iron and the barb being an ordinary T-bar, and these bars are connected and at the saine time separated to a predetermined extent by binding-rods c, which are arranged diagonally and in oppo- 'site` directions and which cross each ot ier longitudinally of the center space between said-bars. In the form of construction shown the rods c are continuous and the bara is provided at intervals with longitudinal slots or openings a2 andthe bar b with corresponding slots or openings 02, which ai'e punched therein from the inner side outwari'lly in the process of making said bars or after the bars have been made, as may be desired, and the binding-rods c are lpassed through the slots or openings and form on the outer sides of tht` bars a and b loops c?, through which are passed key pins or wedges c, which may be ol" any desired shape and size, and in the4 process orforiiiiiig or punching the slots or openings a? and J" corresponding outwardlydirected lugs, ears, or projections a3 and b are lornied on the outer sides of the bars uA and b and at the opposite ends of the slots or openings c2 and bi; but the lugs, ears, or projections ci and l)3 are not an essential feature and may or may not be employed; but said lugs, ears, or projections when formed in the 'manner described give additional strength to the reinforcing device comprising the parallel bars a and b and the longitudinally-arrangcd binding-rods c, which connect said bars in thel manner described. lYlien the bars c, and l) have been connected in the mannerdescribed, they form a rigid truss'work, the bars of which cannot be pressed together or separated, and iii practice a reinforcing device oi this kind may be placed in a column or in a beam or girder, or a number of them may be. placed parallel in the floor and ceiling construction, composed of concrete or similar material, and in all of these cases the concreto Aor similar material entirely incloses the reinforcing device, as indicated by the dotted lines in Figs. l and 2.`

In Figs. 3 and -l l have shown a modification in which parallel bars d are employed, said bars being composed of ordinaryv channel-iron, and passed through the side walls thereof at regular intervals are pins d2, and binding-rods c, similar to those shown in Figs. 1 and 2, are employed for connect-ing the parallel bars d, and in-tliis operation the binding-rods are passed around the oppositelyarranged pins d and in opposite directions and crossing each other between said pins and at the center of the space between the bars d, the binding-rods c being also continuous, as in Figs. 1 and 2. This arrangement of the bindin -rods c firmly connects the bars d and also holds them at a suitable distance apart, and a comparatively strong and staple reinforcing device is thus formed, and in practice this device is embedded in concrete. either in the form of columns, beams, or girders IOO or in floor 'and ceiling construction, or wherever it may be desired, in the saine manner as with the coi'istruct-ion shown in Figs. l and 2.

ln Figs. 5 and l have shown another modification, which is siniilar'in all respects to that shown in Figs. l and 2, except that instead 'of forniingone slot or opening at the points Where the biiiding-rods c`connect Witl'..

the bars a and l) tivo holes e are formed, and the bindiiig-rods c are passed through these holes, and these sepa-rate holes form a web portion or 'tongue over or around Wlhich the i floor and ceiling construction or in slabs a number of them may be placed parallel With each other and bound together by'horizon'tal rods, thus making a horizontal trestle-Work, and this method may also be employed in making vertical Walls, and it Will be understood that in employing columns, beams, girders, and the like in structural Work the ends ol? said columns, beams, girders, and the like will be provided Withthe usual means of connection and supports. y

Although I have shown but tWo forms of bars-namely, channel-iron and T-iron-in the various forms of reinforcing or strengthening devices herein shown and described, it will be apparent that the parallel side bars may be made in any desired sha-pe in crosssection. i

ln addition to the uses herein specified for my improved reinforcing device the same may also be used in railway ties, sleepers, and the like, and it will also be apparent that a structure of this kind may be emploved in certain relations or Wherever such devices are required. i f

Having fully described my inveiition,what

stesse l claim as new, and desire to secure by Leting parallel side bars and connecting-rods arranged diagonallyv between said ars and crossing each other at regularintervals eenm trally and longitudinally betiveensaid bars, said connecting-rods being connected with said hars so as to prevent their outward ,and inward movement, and said connecting-rods being continuous, substantially as shown and described.

2.' A. reinforcing device for use in concrete and similar' structures, comprising parallel side bars and connecting-rods arranged di LTA agonally between said bars and crossing eachV other atregular intervals centrally and longi tudinally between said bars, said connectingrods being connected With said bars so as to prevent their outward and inward move nient, and said connecting-rods being continuous, and said bars being provided with attaching devices around which said rods are passed, substantially as shown and described.

3. A. reinforcing ldevice 'for use in concrete structures, said device comprising parallel bars having-holes punched therethroughat regular intervals,-and continuous connectingl rods arranged diagonally betvifeen'saidfbars and crossing each other in opposite directions and formed into loops which pass tlniougli said holes and through whichgkeyspins are passed on the outer sides of saidbars, substantially as shown and described.

4. A reinforcing device. foriise-'ifn 'concrete structures, comprising parallel side bars,snd

connecting-rods arranged between said bars` and extending longitudinally thereof andl arAUA ranged diagonally and crossing each other at gef i regular intervals longitudinally and centrally i 7 of the space between said bars, said bars being provided with holes through Whichsaid connecting-rods are passechsubstantially as shown and described.

In testimony that l'claimithe foregoing as Y i my invention I have signed myname, in pres ence of the subscribing Witnesses, this 16th day of March, 190,5.;
