ROBERT A. MOORE, OF NEW YORK, N. Y., ASSIGNOR TOV WILLIAM I. LEVY, OF NEW YORK, N. Y.

DOOR-FASTENING DEVICE.

Specification of Letters Patent.

Application filed October 28, 1910.

To all whom it may concern:

Be it known that I, ROBERT A. MOORE, a citizen of the United States, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Door-Fastening Devices, of which the following is a full, clear, and exact speciication.

This invention relates to a class of de. vices for use in conjunction wit-h a night latch to prevent the door of a building from being opened from the outside without the use of a suitable key to operate the latch.

My invention has for its object primarily to provide a form of fastening device wherein is employed a movable bar adapted to be used in a manner to effectually lock the door of a building or an apartment from the inside and which is adapted to coperate with any preferred form of night latch or lock whereby it will be impossible to force the door open from the outside thereof by the ordinary means used for such purposes, but which will permit said door to be readily opened by the person possessing a key capable'of unlocking the latch or lock in use with the fastening device.

A further object of the invention is to provide a base plate to which one end of the ar of my fastening device is swiveled and which is adapted to firmly hold said bar to the wall of the apartment in proximity to the stile of the frame to which the door is hinged; and to provide means adapted to guide the free end of the bar so that it will engage with and be wedged under the slide bolt of the night lock when the door is closed.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claims,

In the drawing, Figure 1 is an elevation of a door and its frame partly broken away wit-h one form of my improved door lock applied thereto. Fig. 2 illustrates the device attached to a wall at a right angle to the door. Fig. 3 is a side view of the bar and base-plate of the door lock. Fig.` 4: is a section through the base-plate and form of swivel for connecting the bar to said base-plate, and Fig. 5 is a perspective view of the guide for controlling the movement of the free end of the bar.

The door fastener 10 has a base-plate 11 which is adapted to be connected by screws or in any suitable manner to a wall, as 12, preferably disposed at a right angle to the stile of the frame to which a door 13 is hinged and upon the stile of the door opposite to the one hinged to its frame may be attached any preferred make of night lock or latch, as 14:. To provide for proper cooperation of the night lock with the door fastener 10 said lock is positioned so that the slide bolt thereof will be disposed in the direction of the hinged edge of the door, that is, reversely to the usual manner of using a night lock.

The base-plate l1 may be of any desired form and to said base-plate is swiveled, as at 15, the member or arm 16 of a bar or locking element 17 of the door fastener 10. The swivel 15 may be in the form of a ball and socket, or a knuckle joint, but the form I prefer is to provide a recess, as 18, in one face of the base-platell and through said base-plate centrally of the recess 18 is an opening 19 in which is rotatably held the pin 20 of the boss 2Oa which is seated in the recess 18 and extends from a flange or cap 21 of the swivel 15 which is provided upon one end of the member or arm 16. To the opposite end of the member or arm 16 is hinged, as at 16a, one end of the bar or locking element 17 or this locking element may be connected in any other desired manner to said arm so as to permit the parts to move at any angle or upon any degree of a circle.

In order to lock the door 13 by the use of my device the bar or locking element 17 is disposed across the face of the door inside of the room or apartment and to allow for using one length of said bar upon doors of various widths the opposite end of the bar 17 is interiorly threaded for reception of the threaded shank 22 of an adjusting member or pin 23. Upon the free end of the adjusting member or pin 28 is provided a head or knob 24 which is adapted to be wedged under the slide bolt of the night lock 14 in locking the door 13 by the device.

It is evident that to open the door which islocked by my device, as described, the slide bolt of the night lock l-ZL must be moved within the casing of said night lock from within the room or apartment or byusing the key adaptedA to unlock the lock 14 from the outside of the door 13. 'When the slide bolt of the night lock 14 is moved from engagement with the adjusting member or pin 23 the door 13 is pushed to an open position,

as indicated in dotted lines 25 Figs. 1 and 2, and the bar 17 will assume a proper angle by means of the hinge 16a, at the same time thermember or arm 16 will be turned ci'rl" justing-member 23 in abutment with said!- door and for the purpose of properly guiding the movement ofthe adjusting member, 23 and said bar I provide a guiding element- 27. The guiding element 27 is provided withay base-plate or strip 28 which is connected by screws or bolts 29 in a vertical position upon the inside face of the stile of the door 13 to which is attached the night lock or latch 14 and the lower end of the strip 2 8 is held adjacent to said night lock; Formed upon one edge of the stri-p 28 is a projectingy :flange Vor Yright Yangle strip 30 which has a cut-out portion or is slotted, as at 31,'for passage therethrough of the slide ybolt ofthe night lock 14 s'o as to allow the knob 24 of the adjustingv member 23 to be wedged thereunder; It isy clear, -that the movement of the llockingelement 17 willbe properlyr guided by Acontact of the adjusting' member 23 with the projecting flange or right angle strip 30 and to prevent the adjustin-g -memloer-123 against disengagement withthe `guiding'element27 when the door 13 is swung clearqopen a retaining member Y or tube 3'2 is provided upon the upper end of the Ebase-plate or strip 28 and projecting fla-nge 30. The tubular member 32 is preferablyv tapering A-in form to provide a `mouth 33 of greater diameter than the top port-ion thereofso yas to allow free access into the interior 4of' said tiibular member of the adj iist ing member or pin 23k of the locking element -or bar 1'7 when the door is opened. f Inthe foregoing ldescription I have em-v bodied the preferred form of my invent-ion, but Ido not 'wish to be understood as liinfiting myself thereto, as Iainaware that modifications may -be made therein without departing from the principle or sacrificing any of the advantages .of this invention, there-v fore I Vreserve to myself the righttomake such -changesfas fallwi-tliin the scopel thereof.
