HINGE 0R CASEMENT-LIFT.

Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed May 22, 1915. Serial No. 29,892. i

To all whom it may concern: 1

Be it known that I, ULYSSES GRANT Mo- QUEEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Hinges or Casement-Lifts, of which the following is a specification. V

This invention relates to a casement lift and has for its primary object the provision of a hinge consisting principally of but a single pair of companion leaves, one of which being fixedly connected to the frame and the other fixedly connected to the casement and free to move in a vertical direction, and it isan important feature in the present invention to so construct the leaves that they may be operatively associated with an extremely simple yet efiective lifting mechanism which'will be operative for the purpose of causing movement in an upward direction to be imparted to the casement on manually controlling said mechanism.

It is a further and essential object of the invention toprovide a casement lift in which a single pair of attaching leaves may be jointly associated or assembled with a lifting mechanism and the latter and the former operatively confined with one another through the pintle which connects the hinge leaves. I V

It is further important that reference be made to the simplicity of construction of the several parts of the device and the manner in which all of said parts can be quickly associated with each other and positively held against derangement without the aid of permanent fastening devices.

It is also desired to state that while simplicity in the arrangement of the parts and the construction thereof is properly cared V for, the arrangement is such as will result in a structure which is light, convenient of operation, positive in its action and durable.

Inthe drawings Figure 1 is a sectional perspective view of aportion of a frame and its casement, showing the application of the lift thereto and illustrating the easement in its normal closed position.

Fig. 2 is a similar view showing the casement elevated.

Fig. 3 is a horizontal sectiontaken on the I line 3'3 of Fi .1.

Fig. 4. is a; a e view or the lie.

' Fig. 5 is a vertical section therethrough showing parts in full lines.

Fig. 6 is a perspective view thereof, showing the leaves opened.

Fig. 7 is a perspective view of the casement leaf.

Fig. 8 is a trio carrier.

Fig. 9 is a leaf. 1

Fig. 10 is a perspective view of the operating handle.

v The device is essentially in the form of a hinge and it is shown to consist of a fixed leaf 1 secured by screws or. other suitable fastenings 2 to the casement frame A and a companion or mating leaf 3, secured by screws or the like lto the casement B. The two leaves normally extend at right angles from the easement frame as shown advanperspective view ofthe frame perspective view of the eccentageously in Fig. 3, and as illustrated-leaf 1 is provided with alined knuckles or loops 5 and 6 and asubstantially U-shaped recess 7 disposed in a horizontal position and having its parallel walls, respectively, merg to also permit the leaf 3 to freely raise and swing upon the pintle.

The lifting mechanism which is employed for the purpose of moving the hinge leaf 3 in a vertical direction upon the pintle 9, consists of an eccentric carrier or block 11 having a vertical knuckle 12 interposed between the knuckles 5 and 6 of the leaf 1, and freely receivingthe intermediate portion of the pintle, and it is illustrated as beingprovided with a substantially oval-shaped hori- V zontally disposed recess 13 open at both sides and provided at its side adjacent to the leaf 3 with a continuous oval-shaped flan e '14:. An eccentric 15 is mounted'to operate 1n the recess 13 and it is-provided with a reduced extension 16 which extends into the opening of the flange 14:, as shown in Fig. 3. The shoulder 17 of the eccentric bears against the flange let and in this manner the eccentric carrier may be confined against the leaf 3 and made to swing therewith. The operating handle 18 occupies a position at one side of the leaf 3 and it carries an angular extension 19 journaled in the leaf 3'and it is further provided with a substantially keystone shaped stud 20 which is fitted in a correspondingly formed passage 21 in the cocentric 15. A threaded extension 22 on the stud 20 extends to one side of the eccentric where it accommodates a clamping nut 23. The adjustment of the nut will cause an operative extension of the eccentric l5 in its receiving slot 13 in the carrier 11 and it will also serve to confine the carrier against the leaf 3. The carrier has a thickness substantially equal to the thickness of the leaf 1 so that it may extend into the recess 7 thereof and come flush with the outer surface of the leaf, as illustrated in Fig. 3.

Through the described arrangement of the several parts of the device, it follows that on moving the handle or lever 18, the eccentric 15 will be revolved in the receiving recess of the carrier and the leaf 3 will be freely raised upon the pintle. The manner of associating the carrier with the leaf 3 also serves to confine said leaf upon the leaf 1 or against separation from the pintle. The device is used in connection with the easement which is designed to be moved first in a vertical direction prior to swinging the casement in a horizontal direction and to effectually cause the casement to pass over the stop strip of the sill C of the casement frame.

When the handle or lever 18 is in the position shown in Fig. 2 the lower edge of the easement is disposed slightly above the mentioned sill stop C, while when the handle is in the position shown in Fig. 1, the lower edge of the casement is properly seated behind the sill stop C. A slight turning of the handle from the position shown in Fig. 2 will cause the casement to gravitationally return to its normal position.

I claim I 1. A combined hinge and casement lift,

comprising, a leaf adapted to be fixed to the frame, a leaf having sliding connection with the first leaf and adapted to be secured to the easement, the first leaf having a recess therein, a member mounted in said recess and provided with a cam-slot, a pin passing through both leaves and through said member, said member coming fiush with one surface of the recessed leaf when the hinge is closed and a cam journaled in the second leaf and having cooperative connection in the cam-slot of said member and provided with an actuating handle disposed at one side of said second leaf and journaled therein.

2. A combined hinge and casement lift, comprising, two relatively swinging leaves one of which being adapted to move vertie cally, a pin connecting the leaves, one of said leaves having a recess therein, a member movable with the other leaf and fitting in said recess when the hinge is closed, said member having a flange formed thereon at one side and provided with a horizontal elongated slot, a cam movable in said slot and disposed at one side of said fiange and an operating handle connected with the cam and jou'rnaled in said other leaf.

8. A combined hinge and casement lift, comprising, two relatively swinging leaves, one of which is free to move in a vertical direction upon the other leaf, said other leaf having a recess, a member free to swing with the first leaf and always disposed directly at one side thereof and adapted to be extended into the recess of the said other leaf when the hinge is closed, and raising and lowering mechanism supported by the other leaf and co-acting with said member, the recess receiving the member therein when the hinge is closed.

In testimony whereof I affix my signature in presence of two witnesses.

ULYSSES GRANT MCQUEEN.
