July 16, 1946. T. J. NYHUS DOOR LOCK ING DEVICE F iled March 19, 1945 2 Sheets-Sheet 2 Inventor Tizeadww Jim @hzw Patented July 16, 1946 noon LOCKING DEVICE Theodore J ohnNyhus, Crane Valley, Saskatchewan, Canada Application March 19, 1945, Serial No. 583,613

This invention relates to an improved door locking device and one of its objects is to provide a device which will positively lock both sides of a swinging door, such as is used on trucks and cars, by a. single turning movement.

Another object of the invention is the provision of a door locking device with a main bolt having on each end a centering head and a looking element, a strap bearing in which the bolt may be turned, and a cooperating keeper for each centering head and locking element secured to the sides of the door frame, whereby both ends of the locking bolt may be locked in the end keepers by a simple turning movement of the bolt in its bearing.

Another object of the invention is to provide simple means for locking the bolt against turning.

With the above and other objects in view the invention consists in certain new and useful combinations, constructions and arrangements of parts, clearly described in the following specification, and fully illustrated in the accompanying drawings, in which- Fig. 1 is a view in elevation showing the improved door locking device applied in working relation to a vertically swinging door of a tail end door.

Fig. 2 is a detail view in elevation, showing one end of the bolt and its cooperating keeper, the locking element of the bolt being shown in insertion position.

Fig. 3 is a detail side elevation showing the bolt handle.

Fig. 4 is a side elevation of one end of the bolt, showing it locked in its keeper.

Fig. 5 is a detail plan view of the handle.

Fig. 6 is a detail sectional view, taken on line 6-6 of Fig. 5, looking in the direction of the arrows.

Fig. 7 is a detail view in elevation of one of the bolt keepers.

Fig. 8 is a View thereof, partly in section, and partly in elevation.

Fig. 9 is a detail transverse sectional view through the bolt, showing its bearing.

Fig. 10 is a fragmentary view thereof in elevation.

Referring to the accompanying drawings, which illustrate the practical construction of my invention, 5 designates a vertically swinging door, which provides a controlled outlet or valve for the main end door 6. The door 5 is hinged along its upper horizontal edge by the usual hinges 1,

2' Claims. (Cl. 292-218) so as to swing upwardly, and this door 5 is considerably smaller than the end door or gate 6.

On the door 5 the cylindrical bearing a is secured by the screws 9, which extend through the integral wing flanges l9 and H thereof. A similar bearing 12 is also secured on the door in axial alignment withthe bearing 8, but spaced endwise from each other so as to provid a normally open clearance between the adjacent ends of the two bearings.

In the two bearings 8 and 12 a single cylindrical bolt I4 is arranged to turn. On this bolt a sleeve i5 is mounted, so as to engage the confronting inner ends of the two bearings and thereby limit the end pla of the bolt in these bearings.

The left end of the bolt is formed with a flattened locking element l6, and a terminal centering head [1, at the outer end of said locking element. The right end of the bolt is formed with another and similar flattened locking element I8 and provided with a centering head 19 at the outer end of said locking element.

The centering head I! and the adjacent looking element 16 are received by the rigid metal keeper '29, which i formed with an opening 2| larger than that of the centering head and having a corresponding form or shape, and with a longitudinal slot 22 which communicates with the opening. The centering head i conical in form, and the flattened locking element is rectangular in cross section, thus providing a bar section which has one narrow side and one wide side. The narrow side l6a is adapted to easily enter the slot 22, but the wide side lfib will not enter this slot, being considerably wider than the slot. The keeper is formed with a circular recess 23, the wall of which is formed with an integral shoulder or stop 24, located on one side of the receiving slot 22.

The locking element l6 of the bolt is adapted to enter the slot 22 of the keeper 20 and to engage the concave face of the recess 23, when the bolt may be turned so that the rectangular looking element will be disposed at right angles to the slot, as indicated in dotted lines in Fig. 8, when one corner portion of the fiat locking elementwill strike against the shoulder or stop 24 and further turning of the bolt will be prevented.

The right end of the boltis provided with another centering head [9 and with a rectangular locking element 18, which joins this head to the shank of the bolt. The centering head [9 and the locking element I8 are adapted to engage the keeper 21, which is secured to the door frame on the side of the sWinging door. This keeper is constructed like the keeper 2D, and need not be described in detail.

When both bolt ends are in locked relation to the end keepers 20 and 21, the door 5 cannot be forced 0r swung, and if great pressure is applied on the door, such as develops from the swelling of grain or saw dust, the centering heads of the bolt, which are formed with right angular inner shoulders 20a and 27a, will be forced against the keepers and thus lock the bolt against endwise displacement from the two keepers. This will subject the bolt to tensional resistance, which will be taken up by the two keepers, which. are attached to the main door or the frame inwhich the small door swings.

By a single turning movement the bolt is thus locked to both keepers against swinging motion,

and to both keepers against load pressure or force due to an unlawful entry effort.

In orderto lock the bolt I provide a handle 28, which has a limited lateral sliding movement on the sleeve I5. Thi handle is arranged to operate the locking pin 29, slidable in the bolt, and adapted to engage the keeper socket 351 formed in the door 5. When the pin 29 is engaged With the socket 30 the bolt cannot be turned.

It is understood that I may apply my improved locking device to all types of swinging doors and movable opening and closing members, and to house and building doors supported on vertical hinges fOr horizontal swinging.

It is also understood that I may make various detail constructional changes, and vary the arrangement and combination of the parts, as shown, within the scope of the claims of this application.

Having described my invention I claim as new:

1. A door locking device consisting of a bolt having a locking element on one end thereof, said locking element being rectangular in cross section and provided With a conical centering head located outwardly of said locking element, and a keeper attachable to the frame of the door and provided with an opening to receive the centering head and a slot to receive the locking element, the keeper having a recess communicating with the slot in which the locking element may be turned at right angles to the slot to lock the bolt in the keeper against endwise displacement and lateral displacement.

2. A door locking device, consisting of a bearing, a. bolt arranged to turn in the bearing and provided with a conical head on each end thereof and a rectangular locking element adjacent. the conical head, and a keeper for each end. of the bolt having an opening to receive the conical head and a slot to receive the locking element, the keeper having a recess in which locking element engaging the same can lock and having a shoulder against which the conical head will bear to restrain the bolt from endwise displacement from the keeper and to lock the bolt against lateral unlocking movement from the keeper.
