HOLDING CLIP ,FOR CGNCRETE REENFORCEMENT;

.Appncanm filed December 25,11923. Serial no; esavev.

The invention relates to certain new-and useful improvements inholding clips for concrete reenforcement- A One of the objects of the invention-is to rovide an improved mesh spacer or wire chair for supportingthe reenforcing structure of concrete members, especially in perpendicular surfaces, before the cementitious material is applied to the same, and before it is set. I Y

Anotherobjectis to provide a combined supporting and spacing means for concrete reinforcements, where the, concrete'is distributed by a cement gun; and one thatavill be completely filled up with the cement.

A further object is to furnish a simple mesh spacer constructed entirely of metal wire that can be easily and quickly fastened to the supporting member by a common nail or the like.

A still further object is to provide a spacer that can be compressed, or knocked down,

from its normal height while itis being placed in position, so that practically any depth of reenforcement may be made by one size of clip.

With these various objects in View, my invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described, pointed out in the claims and shown in the accompanying drawings in which similz have similar numerals of reference attached thereto:

Figure 1 is a side elevation of the preferred embodiment of the invention.

Fig. 2 is a front elevation.

Fig. 3 is a top plan View.

Fig. 4 shows the mesh spacer in position.

Referring now to these drawings, 1 represents my improved wire chair or mesh spacer which comprises, when positioned as more.

particularly shown in Fig. 4, a horizontally placed U or loop 2, merging into two vertically placed Us or loops 3 and a, one on each side of the said first mentioned loop 2. The continuation 5 of the loop 3, and the continuation 6 of the loop 1 then extend horizontally and practically parallel; the right hand one 5 extending forward to about the further end of the horizontal loop 2, then perpendicularly downward as at 7 to the floor 8, and then backward as at 9 to about the outer periphery of the right hand 11' parts vertical loop 3, but spread to the right. The left hand horizontal portion'ti extends for: ward horizontally, butonly for a'shortdis tance bending abruptly backward and d'iagonally downward as at 10 to the'floor, and

' then extending forward as at 11 to about the same length as the right hand leg or member 9. This leg9 is also bent sideways to the: left, the two legs being spread apart about equally, as shown more part cularly 1n Fig.2.

In operating thejinvention, the reenfoi'cing members as 12 are placed over the temporary wooden backingglilw, and are held in place by my hereindescribed mens ear-,1,[o epr the said recnforcing members being shown in Fig. a partly encircled by the two side by side vertical Us or loops 3 and 4. ,A common nail 1a or screw or the like, is then inserted through the upper loop 2 and driven into the backing of wall,- floor or ceiling. The reenforcement now being held in position ceinentitious material or the like is either laid over and between the said mem bers manually or'by the well known cement liquid or plastic material will fill up all around the mesh spacer in every direction, as there are no fiat parallel sides into which the material might-not, and often does not run.

Instead of requiring several sizes of clips for different thicknesses of reenforcement as with other chairs, one size will do. For the nail can be driven into the wood backing more and more, spreading the legs 7 and 10 further and further apart and thus reducing the height of the reenforcing members 12 from the backing 13.

If the entire wall, floor or ceiling had been overlaid by the reenforcing members to a certain height from the backing and the cementitious material had not yet been laid, and it were desired to have said height from the backing less, all of the nails in place could be driven in still further and the legs 7 and 10 spread further apart as at 15, Fig. 2, and the whole set of reenforcing members would be pushed down thereby nearer'the backing.

This mesh spacer can also be made up in large sizes for concrete reenforcing bars,

mally lies over the top of the reenforcing bar, down over the same, as at 16 in Fig. 1, and this will hold the bar tightly in place and there willbe no shitting or turning over, as is liable to happen in other chairs.

As my invention is in some of its aspects generic, I do not limit myself to the details as shown and described, but also contemplate the employment of suitable equivalents that ltairly fall within the scope of my claims.

In this connection I may state that I may 'niake the two forwardly extending members 5 and 6 of the same length, and the loops 2, 3 and i smaller if desired.

Therefore it will be understood that I may make various changes in the detail, form, size and proportion as well as the number and position of the several parts, without departing from the spirit of the invention.

I claim:

1. A mesh spacer comprising a single piece of wire having a horizontal loop, two contiguous vertical loops, and a leg depend ing from each' of the said last mentioned loops, one of the said legs having a foot pointing forward and the other leg having a foot pointing backward.

2. A mesh spacer comprising a single piece of wire having a horizontal loop, two contiguous-vertical loops, a leg portion eX- tending downwardly from one ot the last mentioned loops, a portion extending hori- Zontally trom'the other of said loops, a leg portion extending downwardly from the end of said horizontal portion, and foot porions extending horizontally in opposite directions from the ends of said leg portions.

3. A mesh spacer comprising a single piece of wire having three contiguous open loops, two of said loops being arranged in planes substantially parallel with each other and substantially perpendicular tothe plane of the third loop, leg members extending from each of the two first/mentioned loops in directions away from the third loop, and foot portions at the ends of said leg members and lying in a plane parallel with the plane of the third loop.

In testimony whereof I hereby affix my signature.
