DOOR-CONTROLLING DEVICE.

SPECIFICATION for ing part of Letters Patent No. 523,431, dated July 24, 1894.

Application filed April 23, 1 S94 To all whom it may conoerm Be it known that I, JOSIAH J. KINSEY, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Door-Controlling Devices,

which improvement is fully set forth in the. following specification and shown in the accompanying drawings.

My invention relates to doors adapted to be thrown open by self-acting devices, the invention being adapted more particularly to be used in fire houses to release horses suddenly invention relates to the construction, opera tion and control of said doors.

The invention is hereinafter fully described and more particularly pointed out in the claims. Referring to the drawings Figural is a front elevation of a door with 'myimprovements attached in place. parts acting upon the door. Fig. 3 is a horizontal cross section on, the dotted line 3 3 in Fig. 1, viewed as indicated by arrow. Fig. 4. is a similar cross section of parts at ,the meet- Fig. 5 is a side elevation of a part at the meeting edges of the door, partly vertically sectioned to show an expanding spring. Fig. 6 is across section through a part of one hinge and associated parts taken on the dotted line 6 6 in Fig. 2, partsbeing shown in two positions by full and dotted lines. Fig. 7 is a cross section of a part of the door casing drawn to show more fully the means for controlling the action of some of the parts. Fig. 8 shows more fully the form of a friction stop for the door. Figs. 2, 4, 5, 6, 7 and 8 are drawn to scales larger than Figs. 1 and 3.

Referring to the parts shown, A is the door held to the casing B by hinges O. The parts of the hinges secured to the door are offset as clearly shown in Fig. 6, on account of which when the doors are thrown open they swing back leaving a clear unobstructed opening Fig. 2 is a view ofv Serial ll'o. 608,689.

through the casing, as appears in Fig. 3, so

that when the confined horse hastens out he will not encounter any part of the door;

The two parts of the door are thrown open by means of torsional springs a a held rigidly at their lower ends to the casing. These springsare secured to and act directly upon vertical fan levers I) held to turn in bearings a rigid with the door frame. The fan levers, which are usually associated with the middle hinges of the doors, pass between the two parts of the hinges, as shown in Fig. 6, and

are caused to bear with considerable force upon'the outer parts of the hinges by means of the action of the springs. doors are free or unbol'ted the springs turn the fan levers in their bearings and, pressing against the contiguous parts of the hinges, throw the doors wide open, as indicated.

The springs. are made with sufficient strength to throw the doors back to positions parallel with those occupied by them when closed. But so great a motion is frequently notnecessary, and sometimes objectionable and to regulate the distance through which the doors are thrown back I employ stops (1,

Fig. 7, to limit the motion of the fan levers.

These stops consist of threaded shafts held horizontally in bearings e rigid with the door casing in position to be encountered at their ends by the outwardly moving fan levers. By turning these threaded stops in their. bearings one way or. the other the motions of the fan levers may be arrested at will; and the instant the latter encounter the stops they temporarily cease acting upon the doors which latter continue to move onward from inertia only.

It will be understood that the earlier the fanver is stopped as above described the hinge continues to ride outward 1 upon the brake and so is brought to a stop on account of the friction between the parts.

The brake curves Now when the upward at its outer end so that the friction or resistance felt by the hinge increases as the latter moves away from the fan lever. This brake is made of yielding material as, for instance, spring brass so as to bend slightly downward under the pressure of the hinge.

The brake g is secured to the door casing brake presses successively harder upon the hinge. These two brakes acting in the manner described serve to arrest the motion of the door easily and without shock or jar, and

also hold it with reasonable firmness in place against the action of moderate pressures, as for instance that exerted by puds of wind, and the like.

The doors are closed by hand against the shown, and controlled by an armature connected with some source of electricity in a manner that is common.

I prefer to provide one of the doors with an adjustable edge strip Z, Figs. 3, 4 and 5, formed with a longitudinal groove m fitting over a corresponding tongue n on the main part of the door, as shown. This strip meets the otherdoor as shown and its meeting edge is made concave and the adjacent edge of the other door is made convex so as to close tightly and leave no crack between them. The stripZ is made horizontally adjustable upon the contiguous part of the door by means of horizontal screws 0 passing through it and threaded into the main part of the door.

Springs 19, Figs. 4 and 5, in the groove, secured to the tongue and bearing against the strip, tend to push the latter away from the contiguous part of the door and make atight joint between the two meeting edges of the doors; while by means of the screws the action of the springs may be controlled and the width of the door thus increased or diminished atwill. For instance if the doors shrink and leave a wide crack between them the screws may be correspondingly set out and allow the springs to push the strip outward and close the crack. On the other hand if the edges of the doors bind too tightly from any cause the screws may be tightened up to draw the strip nearer to the main part of the door.

I cover the strip with a sheet 0* of metal, as galvanized iron for instance, as shown, partly for the purpose of protecting the thin or sharp edges of the strip at the sides of the concavity. This sheet of metal is socured to the strip by screws or fasteners s and extended far enough back to lap over the adjacent portion of the contiguous part of the door and cover the joint between said main part and the strip. The sheet metal is free to move upon the main part of the door as the screws 0 are turned, and its free edges may be plain as shown in Fig. 1 or scalloped or otherwise ornamented, as shown in Fig. 5.

That I claim as my invention isl. A door. and its casing provided with hinges, in combination with a fan lever held to turn in bearings in positionto bear against the hinge, and anactuating spring held by the casing and secured to the fan lever and adapted to turn the latter to open the door, substantially as shown.

2. In combination witha door and its casing, hinges for the door, a rotary fan lever bearing against the hinge, an actuating spring secured to the casing and the fan lever and adapted to turn the latter whereby the door is opened, and an adjustable stop to control the action of the fan lever, substantially as shown and described.

3. A door and its casing with hinges to join them, in combination with a rotary fan lever bearing against thehinge,an actuating spring for the fan lever secured to the casing'and serving to throw the door open, and a friction brake fcarried by the fan lever, substantially as shown and described.

4:. In combination with a door and casing and hinges for the door, means for automatically throwing the door open and a friction brake secured to the casin g in position to bear upon the hinge, substantially as shown and described.

5. A door casing, a door formed in two main parts meeting at the middle and adapted to swing away from eachother, and hinges for said main parts of the door, in combination with means for throwing the parts of the door open, one of said main parts of the door being formed with a longitudinal adjustable strip at its meeting edges adapted to be moved toward or from the contiguous part of the door to alter the width of the latter, substantially as and for the purpose specified.

In witness whereof I have hereunto set my hand, this 20th day of April, 1894, in the pres ence of two subscribing witnesses.

JOSIAH J. KINSEY.
