MORRIS DESSAUER AND SAMUEL BARUCH, 0F NEW YORK, N. Y.

FASTENER FOR DOORS, SHUTTERS, AND THE LKE.

To all 'whom t may concern:

Be it known that we, MORRIS DEssAUnR and SAMUEL BARUoI-I, both citizens of the United States, and residents of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Fastener for Doors, Shutters, and the Like, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in locking or bolting means for heavy doors, gates, windows, or other closures, and relates more particularly to the construction and arrangement of parts whereby the bolt or locking member is withdrawn to inoperative position. For fastening the door or other closure, we provide a very heavy, strong bolt or brace so mounted that it cannot possibly be broken or displaced by pressure from the opposite side of the door, and in combination therewith there is provided a bolt or brace-lifting or withdrawing means of such a character that it cannot be operated save upon the insertion of a key of peculiar formation, and this key after being inserted to release the controlling means operates as the handle for operating said controlling means and lifting or withdrawing the bolt or brace.

Reference is to be had to the accompanying drawings, forming a part of this speciication, in which similar characters of reference indicate corresponding parts in all the figures, and in which Figure 1 is a perspective view of the inner side of a door provided with one form of our improved locking means; Fig. 2 is a vertical section through a portion of the door and the controlling means; and Fig. 8 is a perspective view of the inner side of a door provided with a bolt rather than a brace.

The details of the bolt, brace or locking member per se are not of very great importance, as far as our invention is concerned. it is only essential that a bolt, brace or bar be provided of such a character and such size and strength that when in operative position it will positively hold the door against being opened even though sufficient pressure be exerted upon the outer side of the door to break an ordinary lock.

In the specific form illustrated in Fig. 1, the locking bar takes the form of a brace 10, the upper end of which is pivotally secured Specification of Letters Patent.

to any suitable form of bracket 11 on the inner side of the door at a distance above the bottom thereof. The lowe'r end of the brace is adapted to engage with the Hoor at a distance from the threshold, and for receiving said lower end the floor is preferably provided witlra plate or retainer 12, sunk therein so as to be flush with the iioor, and

.having an opening of such size and form as to receive the lower end ofthe brace when the door is closed. The brace thus extends diagonally from the free edge of the door to the floor, and as neit-her end of the brace can slip, it is evident that the door cannot :""ov be opened when the brace is in position.

1n the specific forni illustrated in Fig. 3, the locking bar takes the form of a sliding bolt 13. This bolt is mounted to move `vertically within a dovetailed groove in a plate letcarried by the inner surface of the door adjacent the free edge thereof and adjacent the lower end. The bolt 13 and the supporting and guiding plate 14, are formed of heavy metal, so that the bolt cannot be sheared off by the opening` of the door, and the bolt cannot escape from its guiding plate except by vertical movement. The floor closely adjacent the .threshold is provided with a countersunk plate 15 having an opening therein to receive the lower end of the bolt, said plate being somewhat similar to the plate 14 but disposed in a different position.

For controlling the locking bar, irrespective of whether the same be a diagonal brace 10, a sliding bolt 13, or other movable locking member, we provide mechanism, a preferred form of which is illustrated in section in Fig. 2. This mechanism includes a drum or reel 16 mounted upon the inner surface of the door and co-nnected to the locking member by a suit-able cord, wire or chain 19. The drum or reel has its axis at right angles to the plane of the door, and its ends are supported by ball bearings carried by two parallel plates 17 and 18 of a supporting bracket. The plate 17 is directly secured to the inner surface of the door adjacent the free edge thereof and at substantially the same elevation as the ordinary door knob. The plate 18 has a portion parallel to the plate 17 and spaced from the door so as to support the drum or reel 16, and at o-ne end the plate 18 extends diagonally to the plate 17 and is directly secured to the latter by suitable screws. In the diagonal portion of the plate 18, there is Vpro-vided an opening` 20, so that the cord, chain or wire 19hereinafterreferred to as a cord may extendeither upwardly or downwardly from the reel.

In the form shown in Fig. 1, the cord ex- Vtends upwardly from the reel ordrum to a sheave or pulley 21 adjacent the upper portion of the door, and thence downwardly to thelower portion of the brace, so that the cord in pulling upwardly on the lower'end of the brace will pullmore nearly vertically.

In the form shown in Fig. 3, the sliding bolt 13 is adapted to move vertically and is placed directly below the winding'drum or reel 16, so that the cord 19 preferably eX- Y tends downwardly from the reel andthrough theopening 20.

For rotating'the winding reel, we provide a locking mechanism embodying certain features of what is commonly known in the trade as a Yale lock. VThis includes a barrel Q2 mounted to rotate within a sleeve 23 and to be normally held against rotation by a plurality of tumblers 24, movable Vradially in respect to the barrel. Upon in cross section, so that a rotation of the bar-Y rel is accompaniedby a corresponding rota tion of the reel. The key thus operates not Vonly to release the barrel 22 and the reel 16, so that they may rotate, but it also serves as the handle by means of which the drum and barrel are rotated.

' In order to open a door orother closure which is provided with a lock constructed in accordance with our invention, it is merely necessary to insert the proper key and then turn it in one direction. The continued turning of the key in the same direction winds up the cord on the reel and lifts the locking bar, so as to release the door. After the door has been opened, the cord may be unwound before the key is withdrawn, so

Vthat the door may be locked without inserting the key or the Vkey may be withdrawn Vwith-the cord partially wound upon the reel,

andthe locking bar will thus be held in in` 'operative position until the key isV reinserted vsocket or recess in the floor, a reel or drum secured to the closure, a cord secured to said bar and adapted to be wound upon said reel, and a key-controlled means for rotating said reel. y

3. A locking device -for closures, comprising two substantially parallel plates secured to the inner surface of the closure, a reel supported between said plates with its axis of rotation at right angles to the closure, a keycontrolled and key-operated rotatable barrel extending into the closure from the opposite side thereof and in alinement with said reel and connected thereto, a locking bar carried by the closure and having one end adapted to enter a recess in the floor, and a cord connecting said locking member and said reel.

4. A locking device for closures, compris ing a locking member, a reel having its axis substantially at right angles to the plane of the closure, a flexible connecting member secured to said locking member and adapted to I be wound upon said reel, a rotatable member connected to said reel, and tumblers for normally preventing the rotation of said lastmentioned member and adapted to be moved to inoperative position upon the insertion of a key.

5. A locking device for closures, comprising two substantially parallel plates secured to the innersurface of the closure, a reel supported between said plates with its axis of rotation at right angles to the closure, a locking member for the closure, means connecting said reel and said locking member, and key-controlled means for rotating said reel to operate said locking member.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
