LINNAEUS SMITH NEWTON, OF COUNCIL BLUFFS, IOWA.

LOCK.

Specification of Letters Patent.

Patented Apr. 29, 1913.

Application filed December 14, 1912. Serial No. 736,793.

To all whom it may concern:

Be it known that I, LINNAnUs S. NEWTON, citizen of the United States, residing at louncil Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to door locks and has for its object the production of an efficient locking means in combination with the keeper and latch arm whereby the arm will be prevented from being moved out of engagement with the keeper.

Another object of this invention is the production of an efficient guiding plate in combination with the latch arm and keeper whereby to help guide the arm when same is being lifted and at the same time form an eflicient means for preventing rain or snow entering into the interior of the device.

With these and other objects in view this invention consists of certain novel combinations, constructions and arrangement of parts as will hereinafter be fully described and claimed.

In the accompanying drawing: Figure 1 is a plan view of the device shown upon the exterior portion of the support. Fig. 2 is a view in plan of the interior portion of the lock showing a portion of the keeper housing partly broken away. Fig. 3 is a central longitudinal section of the device. Fig. 4 is a section taken on line 4rt of Fig. 1. Fig. 5 is a section taken on line 55 of Fig. 1. Fig. 6 is a detailed perspective view of the guard frame.

Referring to the accompanying drawing by numerals it will be seen that the device is used in combination with a sliding door 1 and door jamb or support. The support 2 carries a keeper plate 3 upon which the keeper '4: is formed, the inner portion of this plat-e 3 being provided with a thickened portion 5 which is of the same thickness as the keeper 4. The plate 6 is mounted upon the keeper plate 3 by means of the bolts 7 which pass therethrough. The bolts 7 pass through the plate 6, the keeper 3, the support 2 and the support plate 8 mounted upon the outer side of the door. The outer portions or edges of the keeper plate 3 and the plate 6 are beveled inwardly as illustrated at 9 for allowing the latch bar to be easily guided into the interior of this keeper housing and over the keeper 4c.

Mounted upon the interior of the door 1 is a latch bar 10 which is pivotally secured to the door 1 by means of the bolt 11 which passes through one of the apertures 12. These apertures are formed in the inner end of the latch bar 10 for the purpose of allowing the length of the latch bar 10 to be adjusted if so desired. It will be seen that the other end of this latch bar 10 is provided with the finger 13 which is adapted to rest behind the keeper for holding the door in a closed position.

The door 1 is provided upon its inner portion with the guiding plate 1% which is provided with the arcuate slot 15 centrally located in said guiding plate and extending longitudinally thereof. The door 1 is provided upon its outer portion with a secondary guiding plate 16 which is formed similarly to the plate 14 and is also provided with the arcuate slot 17. These two plates are held upon the door 1 by means of the bolts 18 which pass through the door and support the two plates thereon. A protector plate 19 is mounted upon the outer side of the plate 16 and is adapted to cover the arcuate slots 15 and 17 whereby the rain or snow will be prevented from entering into the interior of the car or other device upon which the device is mounted and thereby preventing the several parts from rusting and becoming inefficient in operation. Near the upper end of the secondary plate 16 there is positioned a guiding frame 20 which is provided with downwardly extending legs 21 and the laterally extending feet 22, the feet 22 being approximately twice as wide as the width of the downwardly extending legs 21. The feet 22 are provided with the apertures 23 through which the bolts 24 pass for support-ing the guiding frame upon the secondary plate 16. One end of the protector plate 19 rests within the guiding frame 20 while the lower end of the protector plate 19 is held in position by means of the lifting knob 25 which passes through .the protector plate and through the arcuate slots 15 and 17 and engage the latch bar 10 whereby the latch bar may be lifted so as to allow the finger 13 to be lifted from engagement with the keeper 4 at which time the door may be opened by sliding the same away from the support and keeper housing.

The lower end of the protector plate 19 is provided with a laterally bent flange 26 which is adapted to rest upon the laterally bent shelf 27 formed upon the secondary guiding plate 16. In order to hold the latch bar in engagement with the keeper, the

flange 26 and the laterally bent. portion 27 are provided with the registering apertures 28 through which the locking bolt 29 is adapted to pass. This locking bolt 29 is provided with the transversely extending aperture 30 through which a piece of wire may be placed upon which a seal is carried when the device is carried by a car door or through which a padlock may be placed when the same is used in combination with barns and the like. By referring to. Fig. 2 it will, of course, be seen that the latch bar is provided with a plurality of openings 31 which are adapted to receive the lifting bolt 32 when the bolt 11 is moved to one of the apertures 12.

It will be seen that by use of this device the door will be held in a closed position since the finger 13 of the latch bar 10 engages the keeper 4, but when it is desired to open the door all that is necessary to do is to raise the latch bar by means of the lifting head 25. The protector plate 19 will, of course, be moved through the guiding frame and after the finger 13 is lifted sufficiently the door may be moved back from the support.

It will, of course, be obvious that the door 1 is provided with an arcuate slot which is so formed in the door as to register with the arcuate slots formed in the guiding plates when the same are in position.

Having thus described the invention What is claimed as new, is

In a device of the class described in combination with a door and a support, a keeper 3 from engagement With said keeper when so diesired a protecto -r plate positioned over said 'slots for preventing the rain or snow from entering therethrough, means carried by one of said guiding plates for guiding said protector plate, the lower end of said protector plate provided with a laterally extending flange, one of said guiding plates provided -with a laterally extending shelf, said flange and said shelf provided with a plurality of registering apertures, a locklng bolt pass ng through said apertures whereby said latch bar willbe prevented from being raised from engagement with said keeper when the same is locked.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
