HINGE.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed October 12, 1915. Serial No. 55,570.

the loose pin hinge and the spring pressed hinge and which is so constructed that the .loose pin may be removed and replaced and the leaf members of the hinge separated without demounting the spring element or its connections.

Another object is to provide means for retaining the spring element on one of the leaf members against displacement but which permits of the spring being ad usted to vary its tension and also permits of its ready removal for renewal or repairs.

Another object is to provide a construction in a hinge of the above character wherein the ordinary loose pin. may be employed and in which the pin may be disposed in the hinge from either end thereof so that the hinge may be set in position and employed with either end up.

Another object is to provide means for engaging the opposite ends of the spring element to hold it independent of the removable pin by which one end of the spring is detachably held in fixed relation to the hinge leaf on which it is carried and the other end vadjustably connected to the other leaf member.

Another object is to provide a spring hinge for normally maintaining the closure to which it is attached in a closed position and in which the leaf members of the hinge may be readily separated and reconnected .in removing and replacing the closure.

A further object is to provide a removable pin spring hinge which is simple in construction and is composed of few parts, so

formed and arranged as to be readily constructed and assembled.

The invention is illustrated in the accent panying drawings in which:

Figure l is a view in perspective illustrating the hinge as applied to a door and its casing.

Fig. 2 is a view of the hinge as disposed in an open position showing it partly in vertical section and partly in elevation.

Fig. 6 is a perspective View of the demountable spring retaining shoe.

Fig. 7 is a view in horizontal section on the line 7-7 of Fig. 2 illustrating the manner of mounting the spring adjusting sleeve.

More specifically, 10 and 11 indicate the leaf members of the hinge which are formed with the usual screw holes and are adapted to be attached to a closure and its casing in the ordinary manner. is formed with a tubular cylindrical spring receiving casing 12 which projects from the inner vertical edge of the leaf member and has its ends terminating in spaced relation to the ends of the leaf member. The

cylindrical casing 12 is formed with an open upper end and has an inwardly proecting annular flange 13 on its lower end encircllng a central opening 14 through which a loose pin 15 of the hinge is adapted to extend.

Revolubly mounted on the open end of the cylinder 12 is a spring adjusting sleeve 16 having an annular shoulder 17 interme' diate its ends adapted to seat on the open end of the cylinder 12. The sleeve 16 is cylindrical in form and has portions 18 as to slidably fit the inner wall of the cylin der 12 and is formed with a continuous oir= cumferentially extending channel 20 adapt-- opening in the wall of the cylinder 12 by means of which the sleeve 16 is held against withdrawal from the cylinder but retained in revoluble relation thereto. The sleeve 16 is formed with a central bore 22 arranged opposite the opening 14 and adapted to receive the pin 15.

A helical spring is disposed in the cylinder and has one end engaged by the sleeve 10 and its opposite end engaged by an annular retaining shoe 24:. arranged to seat on the flange 13 and encircle the pivot pin. As a means for holding the shoe Ell. against rotation and at the same time permit of its ready withdrawal and replacement, the shoe is formed with a cut away portion to provide a flat face or shoulder 25 at one side thereof which is adapted to slidably engage a flat shoulder or face 26 on a projection formed at the intersection of the inner face of the flange 13 with the inner wall of the cylinder. The engaging faces and 26 serve as a pin and socket connection or key to hold the retaining shoe against rotation in the casing and permit of winding or unwinding of the spring 3 by rotation of the sleeve 16 in adjusting the tension of the spring and furthermore form a readily de tachable connection between one end of the spring and the leaf member 10.

T he leaf member 11 is formed with a pair of spaced lugs 27 and 28 on one edge thereof which are adapted to be arranged with one of the lugs abutting against the flanged end of the cylinder and the other lug abutting against the outer face of the sleeve 16. The lugs 27 and 28 are formed with central bores and 30 extending therethrough which bores are arranged to aline with the opening 14: and the bore 22 and are pro vided for the reception of the pivot pin 15. T he pivot pin 15 is of such length that when placed inv position it will extend, through one of the lugs 27 or 28 and project through the sleeve 16 and cylinder 12 into the other lug and may be placed in position from either end of the hinge so that the hinge may be employed either end up. A head 31 is formed on the pivot pin 15 which seats on the lug and as a means for finishing the opposite end of the hinge, a knob is pro: rided which is fitted with a threaded stem adapted to be screwed into the bores or 30: these bores being internally threaded for a short distance adjacent their outer ends for the reception of the stem In assembling the hinge the spring 23 is connected to the sleeve 16 and the retaining n1 shoe 24- and is placed in position within the cylinder with the face of the shoe engaging the-shoulder 26 of the cylinder. The set screw :21 is then screwed into engagement with the annular channel 20 of the sleeve 16, thus holding the latter against withdrawal from the cylinder and at the same time cooperating with the spring to hold the retaining shoe in place; the spring 2 being under end-wise compression to exert a pressure on the shoe 2st when disp .sed in the cylinder with the sleeve secured in place. The spring retaining shoe and the spring adjusting sleeve will thus be carried by the leaf member 10 with the spring and shoe incased in the cylinder. The leaf member 11 is then disposed with the lugs 27 and 28 arranged at the opposite ends of the cylinder whereupon the pivot pin 15 is introduced through one of the lugs and through the cylinder into engagement with the other lug; the loose pin sliding into position. The knob 32 is then mounted on the opposite lug to complete the finish of the hinge.

To tension the spring 23 the sleeve 16 is rotated to contract the coils of the spring by turning it in the direct-ion indicated by the arrow (4- in Fig. 3. A removablepin Set is then inserted in one of a series of perforations formed in the periphery of the sleeve portion 19 so as to project outwardly and engage the rear face of the leaf member 11. The spring :23 will then operate to exerta pressure tending to close the leaf members 10 and 11 toward each other in the direction indicated by the arrow 7) in Fig. The pin serves to prevent unwinding of the spring and at the same time provides a connection between one end of the spring and the leaf member 11.

ll hen it is desired to separate the leaf members of the hinge as in removing the closure from its casing, the pin is first removed to relax the spring 23 whereupon the pivot pin. 15 is withdrawn. thereby permit-ting a separation of the hinge leaf members in the manner common in the ordinary loose pin butt hinge.

An important feature of this invention resides in the manner in which the spring is retained in its casing against displacement but subject to adjustment and to ready removal and replacement.

ll hile l have specifically set forth the construction of the hinge as illustrated in the drawings. it is manifest that various changes may be made in its detail construction without departing from the spirit and scope of the invention as set forth in the appended claim.

What I claim is:

In a spring hinge, a. leaf member, a t-ubusleeve against withdrawal from the casing the inner wall of the casing engageable but permitting its rotation in relation therewith the flat face of the retaining shoe to to, a helical spring within the casing having hold the latter" against rotation. 10 one end attached to said sleeve, a retaining In testimony whereof I have signed my 5 shoe arranged within the casing with which name to this specification.

the other end of the spring is engaged formed with a flat face, and a projection on ABNER J. WINDER.
