JOSEPH M. CANNON, OF BOWEN, ILLINOIS.

DOOR-HINGE.

SPECIFICATION forming part of Letters Patent No. 718,423, dated January 13, 1903.

Application filed Febrimry 13, 1902. Serial No. 93.914. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH M. CANNON, a citizen of the United States, residing at Bowen, in the county of Hancock and State of Illinois, have invented a new and useful Door-Hinge, of which the following is a specification.

This invention relates generally to doorhinges, and particularly to that class wherein vertical adjustment is possible without removing either leaf from the part to which it is attached and without changing the countersunk or cut-away portions of the said parts in which the leaves are seated.

The object of the present invention is in a ready, thoroughly efficient, and practical manner to simplify the construction of such a hinge by reducing the number of its parts and incidentally thereby. its cost of production; furthermore, to reduce the labor necessary to effect adjustments to a minimum.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel constructionand combination of parts of a door-hinge, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like numerals of reference indicate corresponding parts, there is illustrated one form ofembodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof.

In the drawings, Figure 1 is a'view in perspective, exhibiting the hinge of this invention applied. Fig. 2 is a viewin vertical section, showing more particularly the construction of the adjustable member of the hinge. Fig. 3 is ahorizontal sectional view.

Referring to the drawings, 1 designates generally the fixed leaf of the hinge, provided in this instance with two knuckles 2, and 3 the adjustable leaf, provided with a single knuckle 4, the two sets of knuckles being held assembled by a hinge-pin 5 in the usual manner. The fixed leaf is provided with a supplemental or bracing leaf 6, formed by bending back a centrally-cut strip of metal and providing this with a flange 7, through which fastenings 8 are passed into the doorframe, the bracing-leaf being disposed at right angles to the securing-plate 9, which latter is also secured to the door-frame in the usual manner.

The adjustable leaf 3 comprisesa securingplate 10, attached in the usual manner to the door, the free edge of which extends beyond the door and is turned upon itself to present a guide 11, theintermediate portion of which is cut away to present a slot 12, in which works the shank 13 of the knuckle member 14, the slot being of greater length than the width of the shank, whereby to permit the latter to move therein to efiect requisite adjustment. The securingplate 15 of the knuckle-bearing member is of greater width than the length of the slot, and by reason of the overturned member 16 of the guide is held permanently associated therewith against possibility of accidental separation, while the knuckle 4, being of greater crossdiameter than the width of the slot, will also operate to prevent separation of the knucklebearing member from the guide. The securing-plate 15 is provided with a vertical slot 17, through which extends a screw 18 into the door-frame, thereby to hold the knuckle member at any desired adjustment upon the door. VVhil'e but one screw 18 is herein shown for holding the securing-plate 15 against the door, it is to be understood that two may be employed, if found necessary or desirable.

Heretofore in hinges of this character it has been customary to provide one member of the sectional hinge with serrations or teeth to engage with similar serrations or teeth in the securing-plate of the hinge with which it coacts, and this arrangement necessitated the loosening of several screws before any adj ustment could be eifected. Moreover, in order that such devices shall be operative it is necessary that the serrations or teeth should perfectly interlock, and where a door needs to be lifted or lowered but a very slight distance it might under some conditions notbe possible to bring the serrations into proper interlocked relation without causing the door to bind in its frame. By the provision of the slotted guide, as described herein, and a knuckle-bearing hinge member having a shank movable in a slot in the guide a door may be raised or lowered as much or little as may be desired and be securely held in place in such adjustment. Moreover, it will re quire but two screws, one for each of the knuckle-bearing members, to hold these positively associated with the door.

In assembling the knuckle-bearing member with the guide-bearing member the portion of metal to constitute the knuckle will be inserted through the slot of the guide before being bent to shape.

It will be seen from the foregoing description that by the manner of assembling the knuckle-bearing member with the guidebearing member of the adjustable leaf of the hinge accidental separation or loss will be positively obviated, and, moreover, that the parts are always associated for proper operation in use. While composed of but few parts, this device will be found thoroughly efficient in use and by reason of the simplicity of its construction will be found to present points of advantage in cheapness of production and an absence of danger of becoming deranged in use.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hinge having a sectional leaf comprising a guide-bearing member, and a knucklebearing member permanently associated therewith and vertically adjustable with relation thereto.

2. A hinge having a sectional leaf comprising a guide-bearing member adapted for permanent attachment to a supporting object, and a vertically-adjustable knuckle-bearing memberinterlocked with the guide and adapt; ed for adjustable attachment to the said object.

3. A hinge having a sectional leaf comprising a securing member carrying a guide provided with a slot, and a knuckle member having its intermediate portion permanently associated with the guide and adjustable in the slot.

4. A hinge having a sectional leaf comprising a securing member carrying a guide provided with a slot, and a knuckle member having its intermediate portion disposed within the slot and its terminal portion of greater area than the slot, whereby to effect permanent association of the parts.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOSEPH M. CANNON.
