(01. tic-1m) The'invention relates to a locking mechanism, as described in the present specification andi1lus trated in the accompanying drawings that form apart of the same.

The invention consists essentially ofthe novel features of construction pointed out broadly and specifically in the claims for'novelty following a description in detail of an acceptable form 'of the'inve'ntion, v I

The objects or the invention are'tofurnish a means for locking doors andFrench windows in such-a way that they will form an auxiliary locking means'to the ordinary locking means in use, whereby any unlawful breaking-in will be materi'al'ly impeded and, at the same time, allow the rightful tenants to enter or leave the premises Figurefi is a cross-sectionalfview ;.of the doubleaction'type of 'locking deviceh-aving the lockfing cylinder and bar detachedtherefrom.

at will; to devise a-lockingmechanisrn preferably having a bar which may be situated on the insideof the door and that can be locked from either within or without; and opened correspondingly';to form an reflective barrier to marauders and to make a lockingi'nechanism as inaccessible as possible and greatly to increase the advan: tages over' the ordinary locking bar atpresent in use, which is hitroducedon the exterior or in I --Figure 12'is antenlargedifragmentary perspec tive detail ofa portion offa door frame showing the locking mechanismioflthe single action type and havingthebar detached'itherefrom. I

, Lil ie: numerals of reference indica-te correspondin partsin the-various figures.

Referring to the drawings, the locking mechanism consists of a tongue locking member as indicated'by. thenumeral vwhich is suitably te'rlor side of the door and'whichis liablev to b tampered with or pmim oua dat the same time being useless if any persons are within the dwelling since they cannot leave while the ordinary'bar is locked in'position on the outside;

and generally to provide a locking mechanism that may be combined with or without a locking bar and which will be comparatively simple in construction and highly eflicientfor its various purposes.

"In the drawings:

Figure 1 is a fragmentary perspective view of the inside of a door and doorframe having the locking mechanism applied thereto and including I v 0 type and having the locking cylinder detached therefrom. o

Figure 4 is an enlarged fragmentary perspec tive detail of a portion of the door frame showing the locking mechanism of thedouble action type and having the bar detached therefrom.

Figure 5 is a cross-sectional view as taken on the lines 55 in Figure 1,

fastened to the outside-surface 23 andthe inside surface 27 of the ,doorlgfram'e 28 by means of screws .or-other fastening members 29, and is provided with-the orifice 3-0 through its outside portion and the slot 34 through-its inside portion whichare for the purpose of receiving the cylindrical loch ,32 and -theflockingtonguev 33. The orifice for the cylindrical lock is so arranged as to be at right angles to, as well asintersecting, the slot 3| for the locking tongue 33.

The door 34 is provided with the brackets 35 and 36 and which are adapted to support and engage with the locking bar 31. This locking bar 31 is pivotally secured to the door frame 28 adjacent to the hinged side of the door by means "of the link member 38 which is secured to the bracket 39 fastened to the door frame, while the other end of the locking bar is provided with a adapted to be brought into alignment with the orifice 30 of the tongue lockingmember 25 when the locking tongue 33 has been placed in the'slot 3 l; and the cylindrical lock 32, engaging with the orifice 30, will extend through the orifice of v the locking tongue 33 and lock in that position.

It will, therefore, be seen that the mechanism as above described has a double action, in that a elevational' view I the tongue will be disengaged with the locking member and pull away from the slot as the door is being opened. I

In the same way a person from the inside may easily leave the premises when the door is locked by simply unlocking the lock 44 and removing the wedge 43 from the locking tongue 33 and then removing the bar 31 therefrom, which enables them to leave the premises.

If he desires to relock the premises, all that he is required to do is simply remove the cylindrical lock 32 from the locking member 25 and thereby the tongue and then, by replacing the bar 31 to the locking tongue 33 and reinserting the wedge 43 and locking the same, he can simply close the door and the locking tongue 33 is brought back in its locking position within the locking member 25 and all that he has to do then is to reinsert his cylindrical lock 32 and the premises are then thoroughly locked.

In this way it will be seen that means are provided for leaving and entering the premises.

In Figure 12, the locking mechanism as shown is of a single action type, that is to say it is locked from one side only and is for the purpose of looking the door from the outside, and it consists, of a similar look as hereinabove described with the exception that the locking bar 46 is provided with a tongue 4! and held together by the clips 41A and the tongue has the orifice 48 and this tongue 41 is adapted to engage in the slot 49 of the look ing mechanism 50 secured to the door frame 5|.

It will be seen that, the essential difference between the two types is in the elimination of the through the door frame for locking the door in its closed position, while an additional locking mechanism may be added by the introduction of a locking bar, according to the particular requirements and uses of the locking mechanism.

It will be obvious that various changes may be made in the details of construction without departing from the spirit of this invention, it is, therefore, to be understood that the invention is not to be limited to the specific details shown and described.

What I claim is: a

1. In a locking mechanism used in conjunction with a door and a door frame, a locking tongue having flanges on the inner side of the door, said locking tongue having an orifice therein, a, tongue locking member secured to the door frame,'said tongue locking member having a plurality of orifices therein adapted to coincide with the said orifice in the said locking tongue when the door is closed, a, locking bar pivotally secured to the door frame remote from the tongue locking member, said locking bar having a recess and adapted to engage in the said flanges in the said locking tongue, a locking wedge adapted to secure said locking bar in the said flanges in the said locking tongue, a lock in the said locking wedge and a cylindrical lock of a diameter equal to the orifices in the said locking tongue, and tongue locking member adapted to engage said locking tongue in said tongue locking member.

2. In a locking mechanism used in conjunction with a door and a door frame, a locking tongue having flanges, said locking tongue having an orifice therein remote from said flanges, a tongue locking member secured to the door frame, said tongue locking member having a plurality of orifices therein adapted to coincide with said orifice in said locking tongue, a locking bar pivotally secured to the door frame remote from the tongue locking member and supported on the door by brackets, one of said brackets having a vertical pin, said locking bar having a recess adapted to engage in said flanges in said locking tongue and an orifice therein adapted to engage with said pin on said bracket, a locking wedge adapted to fixedly secure said locking bar in said flanges in said locking tongue, a lock in said locking wedge and a cylindrical lock of a diameter equal to the orifices in said locking tongue, said tongue looking member adapted to secure said locking tongue in said tongue locking member.
