LOCK-HINGE.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed March 30, 1908. Serial No. 423,982.

To all whom it may concern:

Be it known that I, EDGAR A. GAY, of Rochester, in the county of Monroe and State of New York, have invented certain-new and useful Improvements in Lock-Hinges; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

The present invention relates to lock hinges in which the hinge members are automatically locked in different positions when the parts by which they are carried are relatively adjusted; and it has for an object to provide a reversible hinge that is a hinge which may be used either on the right or on the left hand side of an article of furniture, such as Morris chairs, couches, or the like.

To this and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings wherein I have shown only one embodiment of my invention, Figure 1 illustrates a side view of the hinge with the members thereof at the inner end of their movements. Figs. 2 and 3 inclusive show two intermediate positions of the hinge members. Fig. 4 shows the manner in which a locking device is brought into operation to hold the abutments and the rack members out of engagement; Fig. 5 shows the locking device in effective position; Fig. 6 shows one position during the movement of the hinge members in closing, the position immediately prior to the releasing of the rack member being shown in dotted lines; Fig. 7 is a detail view of the rack member; and Fig. 8 is a sectional view through the device on line aa of Fig. 1.

Referring more particularly to the drawings A and 13 indicate the hinge members pivoted together on a bearing 1 to turn about a common axis, the members being provided with lips 2 and screw openings 3 to receive screws whereby they are retained on any suitable articles of furniture employing two relatively swinging members. In the operation of my present embodiment one of these members should always be maintained in a vertical position, but it matters not which is so held and as a consequence the device may be used either on the right hand side or the left hand side of the furniture. The hinge members in this instance carry the two abutments 4 which are preferably in the form of cylindrical studs arranged below the turning axis of the hinge members. Cooperating with both of these studs is a rack member C which in this instance is formed with a pair of racks 5 and 6 on its lower edge, the racks having their teeth extending in opposite directions and being arranged in diver ent relation to each other, and stops 7 being provided at the ends of the racks. This rack member is mounted to swing preferably about an axis coincident with the turning axis of the hinge and is also adapted to move transversely of said axis being for this purpose provided with a slotted upwardly extending portion 8 which fits loosely about the bearing 9 that is secured to and alined with the bearing 1. With this form of rack member, first one abutment rides over the teeth of one rack and when the stop 7 at the end thereof is reached the other rack is drawn over the other abutment until the other stop 7 is reached.

In order that the hinge members may be moved together when the outer limit is reached, I may provide two downwardly and outwardly extending cams 10 one at the outer end of each rack, the pressure of the abutments on these cams due to the further separation of the hinge members causing the rack member to move transversely of its axis and the racks to move out of cooperative relation with the abutments. The rack member may be held in this position by a locking device which preferably comprises a swinging member 11 in the form of a plate mounted to turn about the swinging axis of the hinge members and the rack member, a bearing 12 being provided for this purpose. T his looking device has two locking portions, one for locking the rack member when the invention is employed as a right hand hinge and the other when the invention is employed as a left hand hinge. In the present instance the locking portions comprise two shoulders 13 with which coiiperates a stop 14 carried by the rack member, the swinging member 11 being formed with a slot 15 in which the stop 14 works during the opening movement of the hinge, and slots 16 extending in opposite directions from the up er end ofthe slot '15 to the shoulders 13 to receive the stop 14 when the cams 1O elevate the rack member so that the locking device can swing under its own weight, as shown in Fig. 4. Upon the release of the parts stop 14 enters behind a shoulder 13 and the hinge members are moved, one toward the other to the position shown in dotted lines in Fig. 6. The locking device is now caused to release the rack memher, this being preferably effected by the engagement of one of the abutments 4 with an extension 17 forming a portion of the locking device, and the engagement of the other abutment with an extension 18 depending from the rack member between the two racks thereon, the extension 18 being beveled at 19 on opposite sides in order that the abutment cooperating therewith may move the rack member transversely of its swinging axis to carry the stop 14 from behind the shoulder 13.

The stop 14 may be in the form of a loop, as shown, in order to provide a means for securing the rack member against abnormal displacement, an opening 20 in the swinging member 11 receiving its other end.

The operation will be understood from the foregoing description and it may, therefore, be stated generally at this point. With the parts positioned, as shown in Fig. 1, when the hinge member B is swung upwardly, the right hand abutment 4 will ride on rack 6 and when right hand stop 7 is reached rack 5 will ride on the left hand abutment 4 until the left hand stop 7 is reached. A further separation of the member causes the locking of the rack member C out of engagement with abutments 4 and this permits the lowering of the hinge member B. The release of the rack member is efiected near the lower limit of movement. I

With a hinge constructed in accordance with this invention it is not necessary to make two sets of dies, one for a right hand hinge and the other for a left hand hinge.

The operation of the device is simple and its parts are few and not liable to become broken. Further, it is inexpensive to manufacture.

I claim as my invention:

1. The combination with a pair of hinge members, of a pair of racks and a pair of abutments cooperating with the racks, one of said pairs being carried by the hinge members, a member carrying the other pair and movable relatively to both hinge members and a device for holding said member so that the abutments will not cooperate with the racks.

2. The combination with a pair of hinge members, of a pair of racks and a pair of abutments cooperating with the racks, one of said pairs being carried by the hinge members, a member carrying the other pair and movable relatively to both hinge members,

and means for automatically locking the last mentioned member in a position so that the abutments will not cooperate with the racks.

3. The combination with a pair of hinge members, carrying a pair of abutments, of a versely of said axis, and a pair of racks carried by said member and cooperating with the abutments, and a device for locking both racks out of engagement with the abutments.
