UNITED STATES PATENT OFFICE.
ANDREW SOHIEFER, OF. HOME CITY, ASSIGNOR TO THE ADDYSTON PIPE AND STEEL COMPANY, OF ADDYSTON, OHIO.
SPECIFICATION forming part of Letters Patent No. 440,724, dated November 18, 1890.
I Application filed May 5, 1890. Serial No. 350,645. (No model.)
To all whom it may concern.-
Be it known that 1, ANDREW SGHIEFER, a citizen of the United States, residing at Home City, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Hinges, of which the follow ing is a specification.
My invention relates more particularly to that class of hinges which are subjected to considerable strains when in use and it consists in a hinge of novel construction.
I have illustrated my invention as applied to a twin pipe-flask.
In the drawings, Figure 1 is an elevation showing a twin pipe-flask to which my invent-ion has been applied. Fig. 2 is a sectional View on the line 2 2 of Fig. 1. Fig. 3 is avertical section of one of the hinges, and Fig. 4 a horizontal section of the same.
A Arepresent the sides of a twin pipe-flask, and B B ears projecting therefrom.
O is a piece of metal, preferably of oval, spherical, or cylindric shape, and hereinafter called a ball, seated within the ears B B and having apertures c and c.
D is a pin taking through the aperture 0 in the ball O, and serving as the pivot of the hinge.
E'E are eyebolts taking into the aperture 0' and pivoted upon the pin D, each eyebolt being secured by a nut 01 to one of the ears B. The aperture 0 is made sufficiently large to allow the bolts to swing on their pivots, and the bolts are preferably curved to bring their points of attachment to the ears directly opposite each other. The ball and ears are preferably so constructed that they will contact at the top and bottom of the pin-'that is, adjacent to the ends of the aperture c but will leave some clearance between the interior surface of the ears and the central zone of the ball bounded by planes at right angles to the aperture. The eyebolts hold the ears in engagement with the ball, and any pressure tending to relative displacement of the sides of the flask in the line of their length is resisted by the ball, thus preventing angular strain upon the eyebolts and greatly decreasing the tendency to breakage oi the latter. The ball also serves to shield the hinge-bolts from the access of molten metal. The cars are preferably cored to form recesses 12 to receive the ends of the pin D, the end walls of the recesses holding the pin against longitudinal displacement. The free edges of the ears are preferably cut away adjacent to the ball, so as to leave bearing strips b at the parts most remote from the pivots of the hinges, thereby decreasing the liability of breakage from the prying action of any solid matter which may accidentally become lodged between the ears. These bearing-strips are usually finished off, and serve to fix the extent to which the flasks or other hinged parts may open.
I claim as my invention- 1. The combination of a ball, a pin taking therethrough, ears taking over the ball, and eyebolts pivoted upon the pin and secured to the ears, substantially as and for the purpose specified.
2. The combination of a ball, a pin taking therethrough, ears adapted to contact with the ball adjacent to the pin, and eyebolts pivoted upon the pin and secured to the ears, substantially as and for the purpose specified.
3. The combination of a ball, a pin taking therethrough, ears taking over the ball and having a bearing-strip upon the edges away from the ball, and eyebolts pivoted upon the pin and secured to the ears, substantially as and for the purpose specified.
4.. The combination of the ears B, having recesses b, the ball 0, having apertures c and c, the pin D, and the bolts E, substantially as and for the purpose specified.
ANDREW SOHIEFER.

J. O. LEMON, JAMES N. RAMSEY.
