CHARLES W. ADAMS, OF PUTNEY, VERMONT.

SHUTTER OPERATING AND FASTENING DEVICE.

To all whom it may concern:

Be it known that I, CHARLES \V. ADAMS, a citizen of the United States of America, and resident of Putney, in the county of Windham and State of Vermont, have invented certain new and useful Improvements in Shutter Operating and Fastening Devices, of which the following is a full, clear, and exact description.

This invention relates to improved devices applicable in connection with window shutters or blinds and the portion of the window casing or structure on which the shutters are hung, and the improvements particularly pertain to means for holding the shutter locked either in its closed, fully opened, or any intermediate position, which are susceptible of being operated to free the shutter so that it may be swung from one to another position as may be desired. And inasmuch as the devices in their preferred form are dependent for their cooperation upon a bodily lifting movement and then a lowering of the shutter, the improvements in part relate to means for permitting and also for securing the vertical bodily movements of the shutter.

The improved devices are hereinafter described in conjunction with the accompanying drawings and set forth in the claims.

In the drawings :-Figure 1 is an elevation as seen at the inner side of a portion of a window casing and shutter showing the improved devices in their cooperative relations,t-he shutter being represented as in its closed position and locked. Fig. 2 is an elevation similar to Fig. 1 but showing the locking devices as released so that the shutter is free. to be swung. are, in substance, plan views as seen below the plane indicated by line 34, the shutter being represented in broken lines and showing different relative positions thereof. Fig. 5 is an elevation of the upper portion of a window casing and the upper portion of a shutter showing features of construction to be hereinafter referred to. Fig. 6 is a perspective view of metallic appliances in which principal portions of the improved devices are included.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents a portion of the window casing and B the blind or shutter. The shutter has as an appurtenance thereof, at its lower edge and near its Specification of Letters Patent.

inner vertical edge the plate or casting C which is screwed thereto and is, to all intents and purposes, integral with the shut ter; and this plate or casting is provided with a comparatively long depending stud a and outside thereof, a depending stud 6, although in practice the depending stud b is duplicated; and each stud b is somewhat shorter than the stud a,these studs 6 being at equal distances away from the location of the stud a and at opposite sides thereof.

D and E represent brackets having horizontal outstanding members secured on the upper and lower portions of the window casing, the distance between these brackets being greater than the height of the shutter, and these brackets are provided with vertically alined holes 0 and 03 respectively for the engagement therein of the upstanding rigid stud e at the top of the shutter and the aforementioned stud a at the bottom of the shutter, these means for journal engagement being such that while the shutter is mounted for its swinging movement through half a circle the shutter may also be bodily lifted owing to the slidable character of its journal constituting parts.

The lower stud a has a downward projection from the shutter in a somewhat less eX- tent than the projection of the stud upwardly from the top of the shutter so that if it is desired to remove the shutter, and the appliances which are carried thereby and which are components in the present improvements, from the window casing, this may be done by bodily lifting the shutter vertically until the lower stud is entirely above the bracket plate E, whereupon the shutter may be by its lower end swung outwardly entirely clear from the bracket and then lowered to disengage its upper stud c from the apertured bracket in which it has its journal bearing engagement. The fact will not be lost sight of, however, that the stud Z) (or pair of such studs as preferably used) is shorter in its downward projection from the bracket plate C than is the journal stud a; and, therefore, in the ordinary usage the shutter may be lifted so that the stud I) may be free and clear from the sockets in the bracket plate E without either of the journal studs a or c becoming disengaged from their brackets D and E. The sockets f f just referred to are arranged in an arc concentrically of the central socket (Z, and

I the shutter bodily so that it may be free to swing, and also for swinging the shutter by reason of its service as a handle, a lever G.

is intermediately thereof fulcrumed on the shut-ter at h and has its arm 2' which inwardly extends from its fulcrum in engagement against the top of the lower bracket, whileadjacent the outwardly ext-ending arm j of said lever for which the finger piece m is provided, is a rigid thumb bearing projection 0 on the side of the shutter.

The shutter being locked in any given set position, by simply pressing from the inside of the window casing with a finger upwardly against the lug or piece on on the arm 7' of the latter while the thumb of the same hand is in bearing against the top of the thumb piece or projection 0, the swung lever will be eifective to pry the shutter bodily upwardly so that its stud b will be out of engagement, and free and clear above the sockets f in the lower bracket plate, and then while the parts m and 0 are still retained in the grasp of the finger and thumb, the shutter may be swung to the position which it is desired that it shall have, and be locked-the releasing of the pressure in an upward direction against the outer arm of the lever Gr permitting the shutter to descend for its stud or studs 7) to engage in the bracket plate sockets f f with which they may be in registry.

For convenience of equipment the plate or casting G which carries the depending studs a and b, is provided at its inner edge with an upstanding integrally formed lug or lip L to serve as a member on which to pivotally mount the lever G.

The shutter working and locking equipments are such as to be practicably produced and carried in stock as builders hardware, and they may be produced in standard sizes at extremely small cost.

While I have shown in the drawings and have described the shutter worker and lock in its preferred details of construction and arrangement, I am expressly not limited in all respects to such details of construction and precise arrangements, as various changes of minor character may be made without departing from the spirit of the invention or sacrlficing any of the advantages thereof.

The duplication of the studs Z) Z) in opposition diametrically relatively to the longer depending central stud a is merely for the purpose of adding stability to the locking engagement of the shutter in any of its given set positions relatively to thelower socketed bracket E.

1. The combination with a window casing having outstanding brackets provided with vertically alined journal bearing apertures, and the lower bracket having a plurality of sockets arranged in an arc line concentrically of the lower journal aperture, of a shutter provided with alined upwardly and downwardly projecting journal studs engaged in said journal apertures, and having at its bottom a depending stud located outwardly beyond its lower journal stud, and

shorter than said stud, adapted on the bodily lifting of the shutter to be disengaged from any of the concentrically arranged sockets, leaving the shutter free to be swung and adapted, on the downward bodily movement of the shutter, to acquire a locking engagement in any of the concentrically arranged sockets, and means'provided on the shutter for bodily imparting a lifting movement thereto.

2. The combination with a window casing having upper and lower brackets, of a shutter journaled in said brackets andadapted to have a vertical movement relatively thereto, the said lower bracket being provided with a plurality of sockets arranged concentrically of the journal axis, a lever fulcrumed on the shutter and having an engagement with the lower bracket, and operative by its swinging movement to impart a lifting movement to the shutter, and a stud projecting downwardly from the bottom of the shutter, located outside of the journal axis and adapted for engagement in any of said sockets.
