WILLIAM W. RAMSEY, OF CHICAGO, ILLINOIS;
METAL REINFORCE FOR CONCRETE.
Specification of Letters Patent.
Patented April 7, 1908.
Application filed July 81, 1907. Serial No. 886,436.
To all whom it may concern? .Be it known that-I, WILLIAM W. RAMSEY, a citizen of the United States, residing at Chicago, in the county of Cook-and State of Illinois, have invented anew and useful Improvernent in a Metal Reinforce for Concrete, of which the following is a specification.
This invention relates to metal bars for reinforcing concrete, and its object has been the production of a form of bar adapted to be shaped by rolling, and which is superior to other bars in the perfect lock it affords to the concrete against movement --longitudinally of the bar.
' The nature of the improvement is fully disclosed below, and will also be understood from the accompanying drawing in which Figure 1 is an elevation of a section or portion of my improved bar. Fig. 2 is a similar view taken at ri ht angles to Fig. 1. Fig. 3 is a section on t e line 33 of Fig. 1. Fig. 4 is an elevation of bar showing it twisted.
In said drawing, 5 is the body of the bar. As seen at Fig. 3, it is substantially square in cross section and it is provided at intervals of an inch or so with transverse projections intended and adapted to form shoulders which will act as abutments to the concrete in which it is embedded and prevent any movement by the concrete longitudinally of the bar. These transverse shoulders are desirably in the form of raised ridges 6, 6 and 7, 7. There are two series of these ridges and each ridge forms a V in outline, with its apex coincident with one of the longitudinal corners of the bar and its limbs extending in diagonal directions across the flat faces which come together at the corner. at the a ices and fade away upon the flat sides. hus in the drawing, 8 is one of the corners to which the ridges 6 are a plied, and 9, 9 are the faces of the bar whic meet at that corner, and u on which the limbs of the ridges are sprea while 10'is the other corner, opposite to corner 8, to which the ridges 7 are 'applied in a similar manner, exce t that the limbs of ridges 7 are preferab y reversed in direction from those of rid es 6.
he ridges 6 and 7 form abutments upon opposite sides of the bar, and effectually resist any tendency by the concrete to change osition longitudinally of the bar. If preerred, the bar may be twisted as in Fig. 4, with the results usually attending that change.
The ridges are highest obtain the full strength of the bar under tension and prevent the elongation incident thereto.
I claim j 1. The concrete reinforcing bar, diamond shape in cross section, and having diagonal abutmentridges, meetin at and extending from the obtuse corners o the bar, said abutment ridges vanishing into the side faces of the bar at the acute angle corners thereof, substantially as specified.
- 2. The concrete reinforcing bar, diamond shaped in cross section, and havingldiagonal abutment ridges meeting each ot or at an angle in pairs at the obtuse angle corners of the diamond shaped bar, and extending to the acute angle corners thereof, said diagonal abutment ridges pointing or extending in opposite directions on the two opposite obtuse angle corners of the bar, said ridges vanishing into the flat sides of the bar at the acute angle corners thereof, substantially as specified.
3. The concrete reinforcing bar, rectangular in cross section, having diagonal abutment ridges meeting each other in airs at two opposite corners of the bar an extending across the adjacent side faces of the bar, said bar having its other two corners smooth and free from projections,-substan tially as specified.
4. The concrete reinforcing bar, rectangular in cross section, having diagonal abutment ridges meeting each other in airs at two opposite corners of the bar an extending across the adjacent side faces of the bar, said bar having its other two corners smooth 4 and free from projections, said diagonal abutment ridges tapering in thickness from the corners of the bar where two side ridges meet towards the smooth corners of the bar, substantially as specified.
5. The concrete reinforcing bar, rectangular in cross section, having diagonal abutment ridges meeting each other in pairs at two opposite corners of the bar and extending across the adjacent side faces of the bar, said bar having its other two corners smooth and free from projections said pairs of diagonal abutment ridges, which meet at one corner, pointing or extending in the opposite direction from those which meet at the opposite corner of the bar, substantially as specified.
6. The concretereinforcing bar, rectan gular in cross section, having diagonal abutment ridges meeting each other in pairs at two opposite corners of the bar and extending across the adjacent side faces of the bar, said bar having its other two corners smooth and free from projections, and said bar being twisted, substantially as specified.
'i. The concrete reinforcing bar, rectangular in cross section, having diagonal abutment ridges. meeting each other 111 pairs, at two opposite corners of the bar and extendin across the adjacent side faces of the bar,
said bar having its other two corners smooth and free from projections, said diagonal abutment ridges tapering in thickness from the corners of the bar, where two said ridges meet toward the smooth corners of the bar, said bar being twisted, substantially as specified.
8. The concrete reinforcing bar, rectangular in cross section, having diagonal abutment ridges meeting each other in pairs, at two opposite corners of the bar and extend ing across the adjacent side facesof the bar,
sald bar having its other two corners smooth and free from projections, said pairs of diagonal abutment ridges which meet at one corner, pointing or extendin in the opposite direction from those Whic meet at the opposite corner of the bar, said bar being twisted, substantially as specified.
