BAR OR FASTENER FOR DOORS.
SPECIFICATION forming part Of Letters Patent No. 698,326, dated April 22,1902.
Application filed December 21, 1901. Serial No. 8d, 77l. (No model.)
To all whom it may concern/.1 Be it known that I, BENJAMIN SOHWAB, a citizen of the United States, residing at Nogales, State of Sonora, Mexico, have invented; certain new and useful Improvements in Bars or Fasteners for Doors, of which the following 'be operated from the inside by a knob and from the outside by a key and which maybe locked in such a way upon' the inside that the key will not slide the bar or bolt to permit the door to be opened. Ordinary bolts,
' bars, or looks furnish butllittle protection against heavy shocks, blows, or against prying from the outside. My invention serves as a secure barrier against successful attempts to enter'the door, even if a key be used, provided the inmates of the house desire to lock the bar from sliding. i
My device may be used with either single or double doors of any width and which swing to the right or left. I I
I attain the objects referred to bymeans of the construction illustrated in the accomp'a nying drawings, which form a part ofthis specification, and in which Figure 1 is a perspective view of a doorfastener embodying my invention. Fig. 2 is a perspective view of a lock and certain attachments thereto which I use in connection with my door-fastener. Fig. 3 is a central vertical section through a ball-bearing 'guide 1 adapted to be secured to the lock. Fig. 4 is a side view and partial section of a guide loop and keeper, to be hereinafter referred to.
Like numerals designate like parts wherever ishey occur in the different views of. the drawngs.
The numeral 1 designates a lockof ordinary or any suitable construction provided with a sliding bolt 1, which may be moved to the right or left by the knob 2 or by the key 3, inserted within the tube 2, said tube designed to be passed through the door and forming a flush keyhole on the outside of said door. The keeper 3 for the bolt 1' is secured to the door-frame or to one of the doors if my device is to be used with double doors. A strong 7 metal bar 4 is mounted to slide to the right or left withthe bolt 1. A ball-bearing guide comprising the two parts 5 6 is secured to the door immediately above the lock 1, a raceway 6' being formed between'the parts 5 6 for the ball 7, a plurality of which balls may be utilized, if found desirable. At one end of the bar 4 a notch 4 is formed, for a purpose which will be hereinafter referred to. The bar 4 is supported at one end in a combined keeper and hinge 8 8, the member 8 of which is securely fastened to the door-frame. Secured to'the bolt 1 is a bracket 9, provided with an integral lug 9, and a loop or guide 10 is bifurcated at its lower end to straddle the lug 9, as will be seen in Fig; 2. A set-screw 11 passes through the upper end of the loop 10 and is adapted to bear against the upper edge of the bar 4 to secure the bar to theloop andv to insure the movement of saidbar when the bolt 1 is moved in either direction. A loop or guide 12, provided with an integral lug 12, Fig. 4, designed to fit and slide in the keeper 14, has a set-screw 13 passed throu'gh'its upper end and adapted to bear against the upper edge ofthe bar 4 to move with said bar when it is desired to permit the bar 4 -to be operated by the key 3. door-frame opposite the hingeS to engage the A keeper 15 issecured to the free end of the bar 4.
The operation of my invention is as follows 2 Whenever it'is desired to bar the door in such a manner that it may be unlocked by the key 3, the set-screw 11 is turned "down to bear with sufficient force against; the bar 4 to in sure the movement of the banwith the loop 10 and the bolt 1. If it is desired to secure the door against the operation of the bar 4 by the key 3,the set-screw 13 is-turned down sufficiently to throw the shoulder of the notch 4 up to engage the upper wall of the keeper 8', the bar 4 being fulcrumed upon the'ball7 to rock sufficiently forthispurpose;
From the foregoingit will beobseryed that my door-fastener furnishes a very secure barrier against intruders, that the devicemay be applied to doors of any width, and that the device is of comparatively simple construction and may be produced at small cost.
It will be understood that a combinationlock may be used instead of the lock and key shown in the drawings;
When the bar 4: has been unlocked, it can be readily removed and set aside until it is necessary to use it again, when it may be instantly replaced for operation.
Having thus described myinvention, what I claim is- 1. A barrier for doors comprising a look, a bar connected to the bolt of said lock to be moved therewith, and a ball-bearing guide for said bar, substantially as described.
2. A bar for doors consisting of'a look, a bracket attached to the bolt of said 1ock,a barrier connected to said bracket to be moved with the bolt, one end of said barrier engaging a hinged keeper, substantially as described.
3. A bar for doors comprising, a look, a bar rier connected to the bolt of said lock, to be BENJAMIN SCIIVVAB.
