UNITED STATES PATENT OFFICE.
GEORGE RUSSELL, or MELBOURNE, VICTORIA, AUSTRALIA.
MEANS FOR ADJUSTABLY SECURING METALLIC MEMBERS.
Application filed August 23, 1915.
To all whom it may concern:
Be it known that I, GEORGE RUSSELL, a subject of the King siding at Nos. 454-160 Flinders street, Melbourne, in the State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Means for Adjust-ably Securing Metallic Members, of which the following is a specification.
This invention comprises improved means for adjustably securing metallic members with the aid of keys, pins or the like.
This invention is particularly applicable to adjustable shear members or stirrups used in reinforced concrete construction and fixed on the tension bars or rods by means of keys, pins, or the like.
The drawings appended illustrate the invention, Figure 1 being an elevation showing the shear member applied to a tension bar and Fig. 2 being a perspective View of the stirrup or shear member.
Referring to these drawings, it will be seen that the stirrups or shear members S comprise a length of Wire or rod doubled toform at one end a loop or cradle 1 into which the tension or other bar 2 fits, the legs 3, 3 of the stirrup being coiled to form convolutions 5 which lie in the planes of the respective legs and extend on either side of said tension bar. A pin or key a is then passed transverselythrough the convohitions 5 and past the bar lying between these convolutions to secure the stirrup or shear member thereto in the desired position.
It will be seen that the loop or cradle l is bent into contact with the legs of the stirrup which legs bear at an inclination Specification of Letters Patent.
of Great Britain, re
Patented Feb. 15, 1916. Serial No. 46,945.
upon the outer sides of said cradle or loop whereby tension on the stirrup tends to 1 tighten the latter on the tension bar but it will be evident that the legs may be arranged approximately vertical or at right angles to the bar 2. The upper part of the cradle or loop 1 is bent the legs of the stirrup so as to be central with the pin 4 and two complete convolutions are thus formed in the legs. The upper ends of the stirrup may be overlapped as at 6 so as to straddle .an upper tension or like bar 7 or the ends may be turned outwardly.
It will be understood that with this invention the stirrup or shear members may be readily adjusted along the tension bar and expeditiously secured and that they may be used to connect vertical rods as in the construction of columns and like vertical concrete-work.
I claim A shear member or stirrup for tension bars comprising a length of wire doubled to form a pair of'arms having a loop at one end, the portions of the arms adjacent to said loop being coiled to form complete convolutions in the arms, which convolutions he 111 the planes of the respective arms, the
latter extending past and engaging the outer sides of the loop, and a pin to pass through the convolutions lying between said oonvolutions at a point diametrically opposite to the point of en- GEORGE RUSSELL.
