ALBERT R. CARROLL, OF J OLIET, ILLINOIS.

HINGE.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed August 31,1904. Serial No. 222.812.

To aZZ whom it may concern.-

Be it known that I, ALBERT R. CARROLL, a citizen of the United States, residing at J oliet, in the county of \Vill and State of Illinois, have invented certain new and useful Improvements in Hinges, of which the fol-lowing is a specification.

My invention relates to the construction of spring-hinges for doors of all kinds.

The especial object of my invention is to provide a spring-hinge in which greater power is obtainable than from hinges of ordinary construction; in which the tension of the spring can be quickly and easily adjusted as may be desired without the use of special tools; in which the adjusting devices are formed as a part of the hinge and are not detachable therefrom; in which the same form of hinge can be adapted to either right or left hand doors; in which one leaf'of the hinge may remain permanently on the door-frame while the other leaf is left on the door when the latter is unhinged, thus avoiding the necessity for removing the attaching-screws; in which the parts can be made by stamping from sheet metal, thus providing economy in the manufacture of the hinge, and in which there are no loose parts to become lost or displaced and plete, taken from the outside of same. Fig.

2 is an elevation of the hinge-spring and the tension-ad ustingcollar secured thereon. Fig. 3 1s an elevation of the hinge-leaf shown at the left hand of Fig. 1, together with the holding device attached to said leaf. Fig. 4c is an elevation of the other leaf, including the pintle and the collar-locking means secured thereon. Fig. 5 is a top plan view of Fig. 3. Fig. 6 is a top plan view of Fig. 4 with the pintle removed,and Fig. 7 a cross-section taken on a line transversely of Fig. 1 and at a point through the collar.

Referring to the drawings in detail, 1 represents the hinge-leaf shown at the left hand of Fig. 1 and which is designed to be secured to the door frame or casing. This leaf is preferablystamped from sheet metal, with the tubular barrel portion 1, which serves asa housing for the coiled spring 6 and. which is cut away at 1 to provide a recess or opening to receive the collar 3. The leaf is further formed at its upper and lower edges with bent-over eyevlugs 1, which are adapted to receive and hold in place the horizontal arms 6 of the spring. It is also provided with a cylindrical portion 1 which serves as a means of securing to the hinge the holding-rod 5. Between the barrel portion 1 and the overhanging flanges l 1 of the leaf are openings 1, which permit the pas sage of the arms of the spring described. Each of the flanges 1 is provided with a hole 1 in its center to receive the pintle 7 when the two leaves are joined. The hinge-leaf 2 is also stamped from sheet metal and bent to form flanges 2 2 atright angles to the face of the leaf, said flanges corresponding in shape to the flanges 1 l of the leaf 1 and adapted to overlie said last-named flanges when the leaves are assembled to form a complete hinge, as clearly shown in Fig. 1. The flanges 2 2 are also provided with suitable holes to receive the pintle 7. Cut and bent up from the body of the leaf are two eye-lugs 2 2 which are spaced apart and form means for connecting to the leaf the collar tension-adjuster L, which is slidably mounted in said lugs. The inner edge of the leaf 2 is turned upwardly, as at 2, and has near its edge an opening through which projects normally the hooked end 4 of the adjuster 1, as shown in Fig. 7 and as indicated by dotted lines in Fig. 4.

The collar 3, which is mounted in the opening 1 in the leaf 1, is formed with radial openings 3 and has an opening 3 extending through its upper and lower sides to receive the bent portion 6 of the spring, as indicated by dotted lines in Fig. 2 and in section in Fig. 7. It will be noted that the spring 6 is coiled in one direction for its upper half and in the opposite direction for its lower half, so that the normal effect of turning the collar 3 will either increase or diminish the tension of both halves of the spring, depending upon the direction in which said collar is turned. The collar-adjuster 4 is composed of a piece of wire bent into the form shown and having the wires brought together and bent upon themselves to form the hook 1* at one side and bent up at the opposite side to said hook, as at 4:", to provide a grasping portion for the fingers, whereby the adjuster may be readily slid back and forth in the bearings provided by the lugs 2 2 The hook 4 is of such size as to permit its be ing readily pushed into and withdrawn from the slots 3 in the collar 3.
