LOCK DEVICE.

A Application filed June 15, 1922. Serial No. 568,378.

To all whom itma-g concern.

Be it known that I, BENJAMIN A. BOOTH, a subject of the King of Great Britain, and resident of Odessa, in the Province of Ontario and Dominion of Canada, have invented certainnew and useful Improvements in Look Devices, of which the following is a specification. v

The principal object of this invention is to provide a new and improved locking means I for garage, barn or stable doors or the like, which will be of very substantial construction and which will be so arranged that it will be impossible toforce or jimmy the doors from the Outside.

Another object is to provid a locking means which will be actuated by the forcehandle being controlled by alock of the so called cylinder type. I

. Another object is to provide means for adjusting the locking bar. to doors of various heights, and a further object is to provide means to adjust the lockingcatches to compensate for warping of the doors.

For the accompl'shment of these and such further objects as will'hereinafter be apparent to those skilled in the art to which this appertains, the invention consists in the construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawings, wherein is shown a preferredembodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which iall'within the scope of the claims hereunto appended.

In the drawing forming a portion of this specification.

Fig. 1 is an elevation of the inside of a pair of doors showing my invention applied thereto.

Fig. 2 is a section on the line 22 of Fig. 1, and

. Fig. 5 is a detail showing the manner in which the actuating handle is connected to the locking bar.

As shown in the drawings, the numerals and 11 indicate the doors to which my invention is shown applied. Secured to the door, 10 at suitably spaced points are the brackets 12, 13, 14 and 15. Slidably mounted in these brackets is a composite locking bar which consists of the end members 16 and 17 preferably of rectangular cross section which are slidably mounted in the brackets 12 and 15 respectively. Secured to the end members 16 and 17 respectively, are 7 the rods 18 and 19, which are provided with right and left hand threads to engage with the tapped holes of an adjusting member 20, said member. being preferably formed to provide a handle or grip as clearly shown in Fig. 2 of the drawing.

The end members 16 and 17 are provided with hook portions 21 and 22' respectively, the hook portion 21 being adapted to engage within a rectangular aperture 23 in a keeper 24 secured to the door frame, while 7 the hook portion 22 is adapted toengage with the keeper 25 secured to the door sill.

The locking bar which is mounted upon the door 11 is slidingly mounted in the brackets 26 and 27, and comprises th end members 28 and 29, the lower ends of which are provided with tapped holes having right and left hand threads respectively, and in which are secured the ends of a connecting bar 30. The end member 28 is provided with a flattened end 31, having the rectangular aperture 32 therein which is adapted to engage over the hooked keeper 33, while the end member 29 is flattened as at 34 to engage with the keeper 35.

Secured to the connecting bar intermediate the end members is a collar 36, having an arm 37 projecting therefrom towards the door 11, said arm being bent at right angles to provide a portion 38 lying substantially parallel to the plane of the door. A longitudinal slot 39 is provided in the portion 38, adjacent th end thereof and slidably receives a pin 40 projecting from a connecting link secured to a sleeve 41 upon the outer end of which is secured an actuating handle or knob 42. The knob 42 is mounted upon the outer side of the door 11 and the interior of the sleeve 41 is provided with a spring lock of the so called cylinder type adapted to automatically prevent the turning of the knobeXcept when the key is in serted therein. Locks of this general type are common and well known and as the lock structure itself forms no part of the present invention, further description thereof is not necessary for the purposes of this application.

Each of the keeper members 24 25, 33 and 35, are provided with longitudinal slots indicated by the numeral 43 to permit the adjustment of the keepers to compensate for any warping of the doors or door frame. Lock nuts 44 are also provided to secure the parts of the bars in adjusted position. The members comprising the locking bars are constructed of metal and are of sufliciently large cross-sectional area to afford sufficient weight to the locking bars to cause them to drop readily into engagement with the keepers. The substantial size of the locking bars is also such that added security is given, making it impossible to spring the bars out of engagement.

It will be noted that the inner lower ends of the hook members 21, 22 and 34 are tapered and that the cooperating keeper members are also tapered to cause the locking bars to be raised over the keepers when the doors are swung to closed position.

The bottom keepers 25 and 35 are of greater transverse width than the catch portions 22 and 34, thereby making it impossible to engage the bottoms of the locking bars and to raise them by inserting a rod under the doors from the outside.

lVhile I have illustrated my invention as applied to doors of the hinged or swinging type, it will be understood that it could be readily applied to sliding doors by merely turning the locking bars at right angles to that shown in connection with the swinging doors herein.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A device of the character described comprising a locking bar having a pair of end members provided with catches, means to secure said locking bar slidably to a door, means to adjust said end members longitudinally, keepers mounted on the door frame adapted to be engaged by said catches when said door is closed, a sleeve mounted upon said locking bar having an arm projecti-ng at right angles therefrom, an actu ating handle mounted on the outer side of said door and means connecting said handle and projecting arm. p

2. A device of the character described comprising a locking bar having a pair of end members provided with catches, means to secure said locking bar slidably to a door,

means to adjust said end members longimembers provided with catches, means to slidably mount said locking bar on a door, a member carried by said bar and having a projecting portion, an actuating handle carried by said door. a connection between said handle and projecting portion having a movement relative tothe latter and capable of actuating said locking bar when said handle is operated and keepers mounted on the door frame and capable of being engaged by said catches when said door is closed. 1 p

4. A device of the character described in cluding a locking bar having a pair of end members provided with catches, means to slidably mount said locking bar on a door, a member carried by said bar and having a projecting portion, an actuating handle carried by said door, a connection between said handle and projecting portion having a movement relative to the latter and capable of actuating said locking bar when said handle is operated and keepers mounted on the door frame and. capable of being engaged by said catches when said door is closed, said keepers being of a greater width than said end members and provided with a shoulder lying between said catches and the door to prevent said locking bar from being raised from outside said door.

Signed atOdessa in the Province of Ontario and Dominion of Canada this 1st day of June A. D. 19'22.

BENJAMIN ALBERT BOOTH.
