H. STIVER, SPACER FOB. R'EINFORQIN G RODS. APPLICATION FILED SEPT. 10, i912 Patented Mar. 4. 1913.

Aria/Mr HARVEY STIVER, OF KANSAS CITY, MISSOURI.
SPACER FOR REINEORCING-RODS.
Specification of Let'ters Patent.
Patented Mar. 4, 1913.
Application filed September 10-, 1912. Serial No. 719,520.
To all whom, it may concern Be it known that I, HARVEY S'nvER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Spacers for Reinforcing-Rods; and I do declare the following to be a full, clear, and exact description of the invention, such as will en-;
able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figuresof reference marked thereon, which form a part of this specification.
My invention relates to spacers for reinforcing bars, and has for its principal object to provide a device of this type which may be supported onform boards without sinking into the form boards when the weight of the reinforcing rods and concrete is placed thereon.
It is also an object of the invention to provide a spacer adapted for supporting the foundation bars in a transverse seat and the crossbars in a pocket over the foundation bars, so that parts of the spacer may be bent over the crossbars when the latter are in .place to permanently connect all of the parts.
In accomplishing these objects I have provided the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein Figure I is a perspective view of a spacer constructed accordln to my invention. Fig. II is a perspective view of a spacer showing the application of reinforcing rods thereto. Fig. III is an end view of the spacer showing its connection with the rods.
Each of the spacers is preferably stamped from a single piece of sheet metal so as to form a seat 1, a forward face 2 and back 3, the seat being com aratively narrow, the front face and backturned upwardly at right angles thereto and the back higher than the face member in order to form the clamping ears resently described. Both of the face and ackmembers are cutaway to form concaved seats 4 within which a foundation rod 5 may seat snugly, the upper ends of the shanks 6, which inclose said seats, being preferably curved in order to completely within the. concrete.
avoid sharp corners and more easily direct a relnforcin rod to its seat.
The shan s7 of the back member 3 are curved forwardlyat their upper, free ends to form months 8 between same and the tops of the forward shank 6, the mouths being of approximately the same width as the diameter of the cross-rod 9 which is to be projected therethrough to gain its seaton the foundation rodbetween the front face and back members. i p The material of which the spacer is formed is preferably slightly resilient in order that the ears 7 of the back shanks 7 may be swung away from the face members to admit the cross-rods, but is adapted to bend over said rods to hold same in place and the'spacer thereto. I
In'using the device, the foundation rods, which, in ordinary practice are about five eighths of an inch in diameter, are laid on the bottom form boards and the cross-rods arranged thereon. After the rods are in place, they are lifted at intervals and spacers placed thereunder so that the larger foundation rods will seat in the concaves 4 and be supported above the form. The smaller cross-rods are then raised slightly and moved between the shank ears 7' and the front shanks of the spacers to spring the After the rods are assembled, with the clamp, the ears 7 are bent over by means of a hammer, or the like, until they fit snugly over the top of the rod, thereby firmly clamping the spacer to the rods and the rods in their overlapped relation. It is apparent that with the rods in this condi tion, when the concrete is poured it will flow beneath the rods as well as thereover,
so that the rods and spacers are embedded It is also apparent that by giving the seat some width it will not be forced into the form boards under weight of the rods, but will stand on fiat connecting portion adapted to seat flush on a supporting form, both members having slots forming upwardly facing rod seats and comprising shanks, the shanks on the back member being longer than those 011 the first member and provided With forwardly curved tips.
In testimon whereof I affix my signature in presence 0 two wltnesses.
