To all whom it may concern:

Be it known that I, JOHN F. YHAVEMEYER,

a citizen of the United States of America,

and a resident of Ardsley-on-Hudson,county of VVestchester, State of New York, have invented an Improvement in Tie-Pieces for Metallic Reinforces, of which the following description, panying drawings,

Heretofore, ties or clips of this general class have generally been so made that in attaching them it is necessary vice under the reinforcing rods.

The character of this invention will be readily understood by referring to the ac companying drawings in which:

The form of the shoulders nhay be varied to suit varying conditions of use. Two

forms are shown in the drawings. In Fig. 1 one of the shoulders on each loop, namely shoulders at and 0 areso made as .to overlap the corresponding shoulders '41. and p and are adapted to pass completely under the lower bar, thus providing firm and positive supports. This form is more particularly adapted for use with heavy bars. The embodiment of this inventionshown in Figs. 3 and 5 is more particularly adapted for use with light reinforces and in this form the shoulders do not overlap. The spring pressure holding these shoulders together-will be ample to prevent the lower rods from slipping out when the clip or tie is thus used. This form of tie can be attached more easily and quickly than the form shown in Figs. 1 and 2.

Figs. 2, 4 and 5 show the devic as it will appear in use. A reinforcing bariy is shown resting upon and supported by a other bar is in turn supported and 0 (the shoulfigure). Fig. 5

'r. In Fig. 2 the bar 0 mainly by the. shoulders m der 0 being hidden in this illustrates the mode of application of the.

second'alternative form of tie, that shown by Fig. 1, and here the four shoulders m, (a, 0, and all coiiperate to support the loweitbar. In both cases the loops or. yokes a and I) pass over the upper bar (1 and hold it in firm engagement with the lower bar 1-. Fig. 4 illustrates the adaptability of the device to different sized rods. The device is so constructed that the loops at andb will tend to spring apart as indicated by the dotted lines in Fig. 4, thus bringing the shoulders m, 'n, o and p into'close engagement with the lower bar.

As indicated above a great advantage which this tie possesses over others of this facility with which it may be attached to'the, reinforcing rods. T apply the clip after rods have been laid -in position upon the temporary molds or centerings the workman grasps the lower rod and lifts it slightly. One of the lower loops of the tie, loop h for instance, may then-be snapped over this lower rod. The loops or runs a and b are then bent bent over the top ported above the centering by th feet, 0, (l,

e and f.

It will be clear that the improved tie-piece may be produced otherwise than from wire,' the latter being used in the presept case sim'- ply to illustrate and explain the invention.

The outline of Fig. 3, for instance, may be regarded as indicating the edges of a strip of resilient metal which would be substantially as effective in carrying out the improvements as is the wire.

I broadest aspect, the invention consists of a resilient yoke illustrated in the present case by the two loops which pass over the top bar) each side member of which is divided so as to form a resilient collar which is sprung around so to engage and hold the lower rod; and the dividing of the side members of the yoke serves to form four-legs, so to speak, upon which the device as a whole is supported upon the centering. And as be fore called to attention, the yoke being resilient, the side members preferably tend to spread apart so as to hold the rods together.

I claim as my invention 1. A tie-piece for intersecting rods in concrete construction, comprising a resilient yoke adapted to embrace one of the rods, each side member of the yoke being divided into two separate parts, thereby providing means to fit over, embrace and hold the other rod. I

.2. A t1e-p1ece for intersecting rods in concrete construction, comprising a resilient Thus, in its yoke adapted to embrace the upper rod, each side member of the yoke being divided into two separate parts to form a loop and.v two independent legs in order to receive the lower'rod and to support the rods above the centering.

3. A. tie-piecefor intersecting rods in concrete construction, comprising resilient yokes adapted to embrace the upper rod, loops formed between said yokes forengagement"with the lower rod, said loops lying in planes at right angles to the planes of said yokes, and downwardly extending projections between each yoke and loop, whereby the rods are held together and supported above the centering.

4. A. combined clip and support for metallic reinforces, comprising a pair of loops to engage and supportone of two intersectisng rods, a pair of yokes yieldin-gly united to the pair of loops to pass over the other rod, and supports formed projections between the said loops and yokes, I

whereby the rods are held in close engagement with each other and are supported above the centering.

5. A combined clip and'support for securing and supporting 'metallic reinforces at their points of intersection, comprising two pairs of wire loops, one pair adapted to engage and support the lower rod, the other pair to engage and pass over the upper rod, said first named pair of loops lying in planes at right angles to the planes of said second pair of loops, and supports formed by the wire between the several loops.

6. A combined clip and support for metallic reinforces, comprising a pair of wire yokes adapted to pass over and engage one of two intersecting rods, said yokes being extended downwardly to form supports for the rods, and'a pair of loops integral with the yokes passing around the other rod,

whereby the rods are firmly held together Y and supported above the centering.

In testimony whereof, I have signed nay name to this specification, in the presence of two subscribing wltnesses.
