TYING DEVICE FOR REENFORCING RODS OR BARS.

Application filed July 26,1922. Serial No. 577,565.

To all whom it may concern:

Be it known that I, DANIEL A. WEDMORE, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have inventand useful Improvements in Tying Devices for Reenforcing Rods or Bars, of which the following is a specification.

My invention consists of a tying device intended for application to the crossed reenforcing rods or bars designed to be em bedde in concrete floors, pavements, roads and the like to strengthen the same, and one object of my invention is to provide a simple, cheap and effective device for locking together and retaining the crossed bars or rods in proper angular relation with respect to each other.

A further object of my invention is to so member that it will effect a locking grip, diagonally disposed, upon the crossed rods or bars, and a still further object of my invention is to simplify the character of the tie and reduce the number of contacting or engaging portions necessary to effect the desired tie or connection of the crossed rods or bars.

These and other features of my invention are more fully described hereinafter; reference being had to the accompanying drawin s, in which:

igure 1, is a perspective view illustrating an improved tie member embodying my invention applied at the junction of a pair of or rods.

Fig. 2, is a plan view of the same.

Fig. 3, is a side elevation looking in the direction of the arrow, Fig. 2.

Fig. 4, is a view of the tying member'in position illustrated in Fig. 2, before being applied to the crossed bars or rods, and

Fig. 5, is a perspective view, similar to Fig.1, showing a modification within the scope of my invention.

It has become quite the practice in the construction of concrete roads, pavements, and the like, to provide a reenforcing layer, or as it is termed, a mattress of crossing rods or bars, and in order that the crossing rods or bars making up such mattress may be held in the proper relative position at right an les to each other or substantially so in or er to give the desired reenforcing degree, they must be firmly secured together or tied at their crossing points. My improved tie member has been designed and is particularly applicable for easily and expeditiously connecting together these rods or bars at their crossing points and holding them against movement with respect to each other.

he crossing bars or rods are indicated at A and B, and for convenience, the bar A will be referred to as a longitudinal bar and the bar B as a transverse bar. The tie member illustrated in Figs. 1, 2, 3, et seq., comprises a single piece ofwire 1, provided at each end with

hooks

2 and 3 respectively, which may be disposed in oppositedirections, and having, intermediate said hooked ends and preferably nearer one and than the other, (the end provided with the hook 2, for instance,) a reversely' bent portion comprising loops 4 and 5, with a short, relatively straight portion 6, connecting these loops. To provide what may be termed a handle for effecting the desired,

leverage in placing the tie in connecting position with respect to the crossing bars or rods, a substantially straight run 7, of convenient length, extends between the loop 5 and the hook 3.

In applying the structure to the crossed bars or rods A and B, the hook 2 may be applied or passed from the left under the transverse bar B, bringing the loop 4 over the longitudinal bar A; said loop 4 lying substantially diagonally with respect to said bars A and B, so that the loop 5 depends below the plane of that portion of the bar B, engaged by the bar A, and into engagement with the side of said bar B, at the right. In such position, the opposite end of the tie member will normally lie substantially in the position indicated by dotted lines Fig. 2, and then, when bent toward the left, with its hook 3 brought under the barB for final engagement therewith, pressure will be applied by the looped portion 5 against the bar B, and said bars A and B will be firmly locked at their junction in right angled position, and permanently retained against displacement.

It will be understood, of course, that while the shape of my improved tie member and its disposition with respect to the crossed bars or rods may be as illustrated in the drawings where-in the hook 2, lies toward the right and the ,hook 3, toward the left, with the loop 4 extending from left to right and the loop 5 at the right, the several portions vone of said loops passing over may be oppositely disposed or arranged without departing from my invention.

It is a simple matter, therefore, to proover the mass of concrete at any stage of its construction, and upon which a course or layer of concrete may be placed; such mattress constituting in the final structure a definite reinforcement for the pavement, road, or the like.

In the form of structure illustrated in Fig.5, I have shown a form of tie member in which the portion providing the hook 2 is extended to provide an additional hook 2 which may overlie the longitudinal bar A when the parts are in assembled condition. Such hook portion 2 may be omitted, however, as indicated in Figs. 1, 2, et seq., without departing from my invention.

I claim:

1. A tie for the junction of crossed reenforcing bars, comprising a wire member having hooks at each end of the same for engagement with one of said bars, a loop arranged to pass over the other bar, and a second 100 disposed adjacent to the first loop and in locking engagement with one of the bars.

2. A tie for the junction of crossed reenforcing bars, comprising a wire member adapted to pass over one oi said bars and having hooks at each end v0t the same for engagement with the other bar, and a plurality of loops between said hooked ends; one of said loops being disposed in gripping or locking engagement with one of the ars.

3. A tie for the junction of crossed reenforcing bars, comprising a wire member having hooks at each end of the same for engagement with one of said bars, and a plu rality of loops between said hooked ends; the other bar, and a second loop disposed in gripping or locking engagement with one of the bars.

4. A. tie for securing crossed reenforcing bars in locked engagement, comprising a.

wire member adapted to pass over one of said bars and having hooks at each end of the same for engagement with the other bar;

reassess said Wire member having adjacent to one hooked end a pair of loops to provide with said hooked end clamping means for one of the bars, and a relativel straight portion disposed between one 0 said loops and the opposite hooked end portion to manipu late the tie device and apply the desired tension when the second hook is engaged.

5; A tie for securing crossed reenforcing bars in locked engagement, comprisin a wire member having hooks at each en of the same for engagement with one of said bars; said wire member having adjacent to one hooked end a loop for passing over the other bar and a loop directly adjacent thereto to afi'ord clamping means for one of the bars, and a relatively straight portion disposed between the second loop and one of the hooked endportions to manipulate the tie device and apply the desired tension when the second book is engaged.

6. A tie for locking reenforcing bars in crossed engagement, comprising a wire member adapted to pass over the upper bar and having hooks at each end of the same for engagement with the other bar; said hooks being oppositely disposed and said wire member having adjacent to one hooked end a depending loop in clamping engagement with the lower bar, and a relatively straight portion of appropriate length disposed between said loop and the opposite hooked end portion to manipulate the tie device and apply the desired tension when the second book is'engaged.

7. A tie for locking reenforcing bars in crossed engagement, comprising a wire member having hooks at each end of the same for engagement with one of said bars; said wire member having adjacent to one hooked end a loop for passing diagonally over the other bar and a depending loop directly adjacent to said diagonal loop in clamping engagement with the lower bar, and a relatively straight portion of appropriate length disposed between the second loop and one of the hooked end portions to manipulate the tie device and apply the desired tension when the second hook is enga ed.

n witness whereof l have signed this specification.
