POST-REINFORCEMENT.

Specification of Letters Patent. Patented Aug, 14 1917,

Application filed February 28, 1916. Serial No. 80,999.

To all whom it may concern:

Be it known that I, DAVID W. Bown, a citizen of the United States, residing at T0- ledo, in the county of Lucas and State of Ohio, have invented a new and useful Post- Reinforcement, of which the following is a specification.

The device forming the subject matter of this application aims toprovide novel means whereby the longitudinal reinforcing elements in a concrete post or beam may be held in spaced relation to the sides and the bottom of the mold, during the molding of the post or beam.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

WVith the above and other objects in view which will appear as the description prooeeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood I that changes in the precise embodiment of the invention herein disclosed can be made within the scope of whatis claimed, without departing from the spirit of the invention.

In the accompanying drawing Figure 1 shows the invention in top plan;

Fig. 2 is a cross section of the structure shown in Fig. 1;

Fig. 3 is a cross section showing a modification;

Fig. 4 is a cross section showing another modification Fig. 5 is a cross section showing a further modification Fig. 6 is a fragmental plan showing one of the strips employed in that form of the invention disclosed in Figs. 1 and 2;

Figs. 7, 8 and 9 are plans showing modifications in the strips.

Referring to Figs. 1 and 2 there is shown a rectangular mold 1 within which are located longitudinal reinforcing bars 2 adapted to constitute a part of the product made in the mold 1. A plurality of crossed rein forcing strips 3 are provided, the same having openings 4 in their ends through which the bars 2 pass removably. The upper ends of the strips 3 bear as shown at 5 against the side walls of the mold adjacent the top of the mold, the lower ends of the straps 8 bear as shown at 6 against the side walls of the mold adjacent the bottom of the mold,

spaced relation to sides and and the lower ends of the strips 3' bear as shown at 7 against the bottom proper of the mold.

Qwing to the construction last above described, the bars 2 will be held in proper to the bottom of the mold and the weight of the reinforcing elements 2. and 3 will be carried by the .hereinbefore set forth, and cross strips 14 connect the bars 10 and 9 as above described. One of the strips 12 abuts as shown at 15 against the side wall of the mold 8 adjacent the top of the mold. The lower end of the other of the strips 12 abuts as shown at i I 16 against the side of the mold, the lower end of the sald strip 12 abutting as SllOWIl' at 17 against the bottom of themold. Those strips 12 and 14 which are connected with the lower bar 10 abut against the bottom of the mold as shown at 50. The upper end of one of the strips 14 abuts as shown at 18 against the side wall of the mold 8 adjacent the top. of the mold. The lower end of the other strip 14 abuts as shown at 19 against the side wall of the mold, the lower corner of the said strip abutting as shown at 20 against the bottom of the mold.

From the foregoing it will be observed that in that form of the invention disclosed in Fig. 3, as in the form disclosed in Fig. 2,

the strips cooperate with the sides and the bottom of the mold and to hold the longitudinal reinforcing bars positioned with respect to the mold, so that when the concrete is poured into the mold, the longitudinal reinforcing bars will be arranged in proper positions with respect to the outer surface of the product.

In Fig. 4 there is shown a mold 21 which is of approximately triangular contour, the mold 21 including upright sides 22 and inclined sides 23 merging into a bottom 24. Longitudinal reinforcing bars 25 are disposed within the mold 21 adjacent thetop of the mold, and a single longitudinal reinforcing bar 26 is disposed within the mold, adjacent the bottom 24 of the mold. Crossed strips 27 are provided, the upper ends of the crossed strips 27 being mounted on the bars ject a strip 40 provided with 25, and the strips 27 at their point of crossing, being mounted on the bottom bar 26, in the manner hereinbefore set forth. At their upper ends, the strips 27 bear as shown at 28, against the sides 22 of the mold, the lower ends of the strips 27 bearingagainst the bottom 24 of the mold as shown at 29.

In Fig. 5 of the drawings, there is shown an approximately triangular mold 30 comprising inclined walls 31 defining a bottom 32. Bars 33 are located within the mold 30 adjacent the top of the mold, and within the mold 30, near to its bottom, is placed a longitudinal bar 34. Cross strips 35 are provided, the upper ends of the strips 35 being mounted on the bars 33, and the strips being mounted, at their point of crossing, on the bottom bar 34. Near their upper ends, the strips 35 are equipped with'outwardly extended projections 36 which bear on the side walls 31 of the mold. The inner corners of the strips 35 are cut away as shown at 37 so that the corners of the strips will not prooutwardly through the concrete. As shown at 38, the lower ends of the strips 35 bear on the bottom 32 of the mold.

In Fig. 6 of the drawings, the strips 3 are shown as provided with rectangular end edges 39. In Fig. 7 of the drawings there is shown an opening 41 and with a rectangularly disposed end edge 42. The strip may be reduced, intermediate its ends, to form a neck 43.

In Fig. 8 of the drawings, there appears a strip 44 provided, as will be understood, at both ends, with openings 45, the strip 44 Copies of this patent may be obtained for haging a V-shaped notch 46 in each of its en s.

In Fig. 9 of the drawings, the numeral 47 denotes a strip having openings 48 adjacent each of its ends, each of the end edges of the strip being provided with concaved notches 49.

In any form of the invention, it is not necessary that the crossed strips be in contact. The strips may be placed at any desired distances apart, along the rods, as shown in the case of the strips 3 in Fig. 1.

Having thus described the invention, what is claimed is A reinforcement of the class described, comprising straight, parallel rods; and crossed strips provided at their ends with openings lying entirely within the contour of the strips, the rods being loosely received in the openings, whereby the strips may swing transversely on the rods, to'eifect an expansion and a contraction of the reinforcement, and to permit the reinforcement to fit in molds of diiferent cross-sections, the loose mounting of the strips on the rods, permitting the strips to be shifted longitudinally of the rods, whereby the strips may be ar ranged in groups at points between the ends of the product of which the reinforcement constitutes a part.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
