OPERATING AND LOCKING MEANS FOR DUDE-S AND WINDOWS,

Application filed August 24, 1922. SerialNo. 584,007.

To all whom c'tmag concern:

Be it known that I, HARRY C. PHILLIPS, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Operating and Looking Means for Doors and Vindows, of which the following is a specification, reference being. had therein to the accompanying drawings.

My invention relates to casement windows and so-called French windows and doors, all of which operate upon the same principle of a swinging leaf.

The object of the invention is to improve the construction and arrangement of such windows and doors in the matters of raising and lowering, swinging and locking the same. An ancillary object is to enable my.

principal object to be carried out with standard hardware and millwork.

In order to attain my objects I provide in a casement window, as an example, a rabbeted sill over which the casement swings in opening and closing, and outside. of which it drops in locking to make a weather-tight joint at the bottom. Vertical play is permitted in the hinges, and the raising and lowering of the sash is done by means of a cam lever which I shall describe and claim as an essential part of my invention.

The invention is illustrated in the accompanying drawings in which:

Fig. 1 is a face view ofa casement window with parts broken away showing the hardware attached;

Fig. 2 is a vertical section on the line 2-2 of Fig. 1; I

Fig. 3 is a horizontal section on the line of Fig. 1;

Fig. 4 is a face view on an enlarged scale of the cam lever and one hinge;

Fig. 5 is a face view of the hinge of Fig. l;

Fig. 6 is a face view of the mounting parts of the cam lever separated; and

Fig. 7 is an edge vlew of the same. Referring to the drawings, 1 is the inner sill, 2 is the sash of the easement, 3 is a stop,

and 4 is the outside trim, all these being standard millwork. 5 is a hinge, one leaf of which attached-t0 the sash, has vertical play on the fixed pintle, and 6 is the cam lever by which the sash is raised and lowered, and upon which it is supported while swinging.

Referring to Fig. 4, which shows the lower part of the hinge side of one sash, the cam lever 6 has a shank 6 a head 6*, and a cam body 6, formed eccentrically around the pivotal center 6 upon which the lever turns. The head 6 is notched at 6 to provide a Linen shoulder 6, which when the lever isvertical and the sash is lowered, rests against the lower fixed part of the hinge 5, thus form ing a look as well as a stop to limit the movement of the lever. The cam body 6 has a face 6 normally, when the lever is vertical, resting on the sill 1, and a face 6 which rests upon the sill when the lever is down and the sash raised for unlocking. The locking position is shown in full lines in Fig. 4;, and the unlocked or swinging position of the parts is shown in dotted lines.

The mounting parts in Figs. 6 and 7 comprise a base plate 7 adapted to be screwed to the corner of the sash frame, as indicated in the face view in Fig. 1. Upon this base plate is a bearing hub 7 to receive the cam lever which turns thereon, and is held in place by the cap plate 7 The cap has a squared pro jection '7 fitting into a squared socket 7 in the hub 7 and the parts ar'esecured together by a screw 7 with the result that the constant turning of the lever on the hub has no tendency to loosen the screw.

The operation of the parts thus described is as follows: The sash being open, is swung outward until its inner face is flush with the outer face of the inner sill l, the lever 6 be ing then horizontal. The lever is then turned around the hub 7 centering upon the observed that as the cam face 6 on the lever rests upon the sill inside of the pivot 6 the weight of the sash holds the lever-in vertical position and thus maintains the parts in locking position.

Inasmuch as there must be some space for play of the head of the sash, in rising and falling, I provide a drop molding to cover the outside face to a depth somewhat greater than the vertical movement, or as an alternative, I may provide a filler to be inserted in the opening, and which will serve when in place as an additional lock. The gist of my invention however, lies in the construction and interlocking relation of the cam lever 6 to the hinge 5, the cam lever also serving as a support for the sash or door while it 1s swinging.

- feet a flat shoewhich travels over the sill and in order to take up the wear I provide a metal bearing plate on the sill as indicated at 1 in Fig. 4.

I shall use the expressiona hinge leaf in the claims as meaning a swinging easement, sash, a door or French window. When applied to a door, the handle 6 on the head of the lever 6 may be modified so as to be operable by the foot instead ofthe hand.

I- claim:

1. The combination of an open frame having an inner sill, a swinging leaf hinged on the side of. the frame with vertical play in the hinges to permit the leaf when closed to drop outside the sill, asill late, and a cam lever pivoted at the bottom of said leaf substantially beneath one hinge, said lever having cam faces adapted t0 rest and travel upon the sill respectively, and a head" adapted to The cam face 6 forms in eliengage said hinge with means to lock the sash against vertical movement when the parts are so engaged.

2. In combination with a swinging sash or door and a fixed sill, means to raise and lower theswinging; part outside the sill, comprising a lever pivotally attached to the swinging part nearthe sill and having a twopart eccentric own body, one part being flattened and forming a shoe adapted to slide over the sill.

3. In combination with a swinging sash or doorhaving vertical movement on its hinges, a hinge having a fixed lea-l a pintle secured at opposite ends of said leaf; with locking means for the pintle overlying the pintle at both ends, together with a movable leaf having both end play and rotary motion on said pintle.

In testimony whereof I hereunto ailix my signature.

HARRY C; PHILLIPS.
