MEANS FOR POSITIONING PAVEMENT REENFORCING. I

Our invention relates to a means for positioning pavement reenforcing, and the objects of our invention are: first, to provide a positioning device of this class which will hold reenforcing in a predetermined or specified plate while pouring the plastic material, second, to provide a device of this class which will eliminate cumbersome supports; third, to provide a device of this class which may be readily and easily removed after pouring, leaving nothing but the reen- V forcing in the pavement material; fourth, to provide a device of this class which will permit the paving material to surround the reenforcing; fifth, to provide a device of this class which is easily operated, durable, eflicient, and which will not readily deteriorate or get out of order, and sixth, to provide a novel method of positioning pavement reenforcing.

With these and other objects in view, as will appear hereinafter, our invention con sists of certain novel features of construction, combination and arrangement of .parts and portions, as will be hereinafter described in detail and particularly set forth to theaccompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure 1 is an elevational view of our de vice shown 1n position on the roadway,

. which roadway is shown in section through .1-.1 of Fig. 2; Fig. 2 is a top or plan view of the positioning means in place on the roadway; Fig. 3 is an enlarged elevational' view of a portion of our devlc-e with the concrete removed and the reenforclng and header member shown through 33 of Fig. 2 to facilitate the illustration; Fig. 4is a side elevation of my device in a modified form from that of Figs. 1, 2 and 3, with the concrete removed and the reenforcing bars and header in section; Fig. 5 is an edge view Application filed January 13, 192?. Serial No. 160,955.

principal parts and, portions of invention. 7 v o The supporting means 1 is preferably 'made of pipe flattened at the ends 1*, doubled backagainst itself'at 1, and bent downwardly at 1 as best shown in Figs. 1 and 3 of the drawings. The portions 1 are bent downwardly so as to prevent the bar 1 from porting bar 1 are a plurality of positioning levers 2. These members pass throughv the holes 1 and are adjustable by means of the threads 2*. The lock nuts 2 and washer 2 look the positioning lever in position, but permit it to turn freely. v The upper portion of the lever 2 is bent to form a handle 2- and the lower portion is bent to form a supporting lug 2, which holds the reenforcing R. It will be noted that the positioning members are rights and lefts to each other. This is to keep the reenforcing R from shifting when the concrete C or other plastic material is poured.

The operation of the device is as follows:

Several of the devices are placed between the headers, H, with the supporting rod 1 and positioning levers 2 in the position shown by the solid and dotted lines in Fig.

l of the drawings. The levers 2 are adjusted to the required position and the reenforcing R placedon the supporting lug 2*. Then the concrete is poured around the reenforcing] The levers are then turned until they assume the position shown by the dotted lines in Fig. 1 of the drawings and-the 'device is removed without disturbing the reenforcing. I

The modified form, shown in Figs..4, 5 and 6 of the drawings, is used to hold the reenforcing R near the header H. The sup-: porting frame is composed of members 3 and 8 rigidly secured together at 3 and forming a U-shaped portion with the member 3 This Ushaped portion slips over the header H and supports itself in position. The remaining portion 3 of the L-shaped .member '3 extends outwardly from the header H and near its outer end is a hole 3 adapted to receive the lever member 4. A member 3 connects with the member 3 is bent near its upper end to form the handle 4 The rod passes through the collar 5, through the hole 3 of the member 8 and through the hole 3 in the member 3 Po :siti'oned on the lever rod 4 is aplurality of supports .6, which can be 'clampec in any desired position on the rod by means of bolts '6 oneend'of the support 6 is a lug 6 x'vl ichdieeps the 'ree'nforcing R from slipping offthe support. This lug, it will be noted, is beveled so that it may slide under the reenforcing rods when the lever is turned.

The operation of the modified device is as follows Several of the positioning 'means are placed along the header H, and the lever with the supports is positioned as shown in Fig. 4 of the'drawings. The reenforcmg R isplaced on the supports 6 and the concrete is poured. Then the lever is turned, causing the pin?) tofollow the slots 4? of thecollar -4. The support is lowered .as the leveris' turned, causing the lug 6 to miss the reenforcing R, and assumes the position shown by the dotted lines in Fig. 4 of the drawings. Then the device may be removed from the concrete without disturbing the reeuforcing.

Though we have shown and described a particular construction, combination and arrangement of parts and portions and a certain modificationv thereof, we do not wish to be limited to this particular coi'istruction, combination and arrangement nor to the modification, but desire to include in the scope of my invention, the construction, combination and arrangement substantially as set "forth in the appended claims.

Having thus described our invention, what we claim as new and desire to secure'by Letters Patent is 1. In a means for positioning pavement reenforcement, a horizontal support secured to the headersat its opposite ends and provided with plurality of vertical holes "therethroug'h', a handle member provided with right angle turns on its opposite ends, the main portion extending through each ,of said holes, and means'mounted on the main portion of'said handlemember ada ted-to be shifted thereon for adjusting the position of said handle member relative to said support.

2.111 a means for positioning pavement reenforcement, a horizontal support secured to the headers at its opposite ends and provided with a plurality of vertical holes therethrough, a handle member provided with right'angle turns on its opposite ends, the main portion extending through each of said holes, means mounted on the main portion of said handle member adapted to be shifted thereon for adjusting the position of said handle member relative to said support, and means for securing said support relative to the pavement headers atit's opposite ends.

In a means for positioning pavement reenforcing, horizontal supports with vertical openings therein, a vertical-supporting menrber with a handle at right. angles thereto at its upper end and with laterally extending supporting members positioned along the vertical portion thereof adapted to receive the concrete reenforcing and support the same, and adjusting means for Supporting said verticalmember relative to said horizontal supports. a

4. In a means for positioning pavement reenforcing, horizontal supports with vertical openings therein, a vertical supporting member with a handle at right angles thereto at its upper end and with laterally extending supporting memfloers positioned along the vertical portion thereof adapted to receive the concretereenfo'rcing and sup port the same, adjusting means for supporting said vertical member relative to said horizontalv supports, and. means for securing said supports on the headers for the concrete pavement.

5. In a means for positioning pavement reenforcing,horizontal supports with vertical openings therein, a vertical supporting member with a handle at right angles thereto at its upper end and with laterally extending supporting members positioned alongthe vertical portion thereof adapted to receive the concrete reenforcing and support the. same, adjusting. means for supporting said .verti'cal member relative to said horizontal supports,'means for securing said supports on the headers for the concrete pavement, and means .for supporting said horizontal supports intermediate their ends.

Intestimony whereof, we have hereunto s'etour hands at Jacumba, California, this 31st day of December, 1926.
