BOX CENTERING SHAFT Filed Feb; 21,, 1950 INVENTOR WITNESS 71 4 .flraZ'e.
ATTORNEY Patented Mar. 22, 1932' PATENT ()FFICE f WHITTLESEY A. DRAKE, F, BEAUMONT, TEXAS BAR 'CENTERING SHAFT Application filed February 21, 1930. Serial No. 430,303.
My invention relates to vbar centering shafts for holding reinforcing bars for concrete work in position while the concrete is being poured- An object of the present invention is to provide a device of this character which is formed from a single length of rod thereby obviating the detachment and loss of any of its parts, and in addition results in an article which is less expensive to manufacture than those now in use.
A further object of the invention is to pro-, vide a device of this character embodying, a ground penetrating shank having a laterally extending loop formed therewith which may be utilized to anchor wire mesh as well as to support a reinforcing rod for concrete or other plastic work.
The invention also contemplates a reinforcing, rod supporting chair wherein the loop is so formed as to efficientlv support the reinforcing rod and permit the latter to be readily engaged or disengaged from the loop.
With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangements of parts and operations to be hereinafter more fully described,
claimed and illustrated in the accompanying drawings, wherein:
Figure 1 1s a side elevation of my improved rod supporting chair" in use, the rod being angles to Fig.1; and
Fig. 3 is a bottom plan view of the device and Fig. 1 is a view similar to Fig. 2 but lookingfrom the opposite side of the device.
The invention comprises a length of rod 5 having a longitudinally extendingshank adapted to be driven into the ground. To facilitate entrance of the shank into the ground it is provided with a lower tapered 7 end 11.
At its upper .end the length of rod is bent upon itself to provide a laterally extending loop for the reception of the usual reinforcing rod designated at R.
The loop 15 has'a laterally curved terminal portion 16 whose free end is located in transverse alinement with the shank 10 and is located a suflicient distance from the shank as to provide an entrance for the rod.
Normally the reinforcing rod is supported in the loop as shown in Figs. 1 and 2. However, when'it is desired to engage or disengage the rod with the loop the device is rotated to the position shown in Fi 3 where the terminal portion 16 will lie substantially parallel to the rod. When in this position the rod may be engaged with the loop by ro--' tating the device in a direction to cause the terminal portion 16 to ride under the rod and;
sustain it as shown in Fig. 1.
What is claimed is:
1. In a reinforcing rod supporting and centering chair, a length of rod bent to provide a shank, the upper end of the rod being bent upon itself to provide an eye which is open at one side for engagement and disengagement of the reinforcing rod.
2. In a device of the character described, a
length of rod bent to provide a straight shank so I portion and a rod sustaining loop at one end,
the loop having a terminal portion which is laterally curved away from the shank.
3. In a device of the character described, a
length of rod bent to provide a straight shankv ally extending loop carried thereby, theloop having, a laterally curved terminal portion which curves away from the shank and constitutes a support for the reinforcing rod.
