PATENT PETER F. AUG-ENBRAUN, OF STAMFORD, CONNECTICUT, ASSIGNOR TO THE YALE & TOWNE MANUFACTURING COMPANY, OF STAMFORD, CONNECTICUT.

AUTOMOBILE-DOOR LOCK.

Application filed June 30, 1922. Serial No. 572,004.

To all whom it may concern:

Be it known that I, PETER F. AUGEN- BRAUN, a citizen of the United States, and a resident of Stamford, in the county of Fairfield and State of. Connecticut, have invented certain new and useful Improvements in Automobile Door Locks; and I do here'- by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 4

My invention relates to an improvement in looks designed more particularly for use on automobile doors, the object being to provide a bolt deadlocking device with actuating means which do notdepend upon the construction of the lock for its support, and

which can be used in any position required by simply boring a hole in the door at the desired point, and it consists in the parts and combination of parts as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of a lock embodying my invention. Figure 2 is a view in section through the door and frame and showing the preferred means for locking the cylinder of the pin tumbler lock in place. Figure 3 is a view in edge elevation partly in section of the door, showing the pin tumbler lock and its securing means and also the connecting bar which actuates the dead locking means. Figure 4 is a view in section on the line 44 of Figure 2. Figure 5 is a view in section of a modified form of cylinder securing means. Figure 6 is a view similar to Figure 2showing the means shown in Figure 5 for looking the cylinder in place. Figure 7 is a View in section on the line 7-7 of Figure 6. Figure 8 is a view in edge elevation of a door embodying the constructionshown in Figure 6. Figure 9 is a view in front elevation of the pin tumbler lock. Figure 10 is a view in section showing the connection between the plug of the pin tumbler look, and the connecting bar. Flgure 11 IS a view" of the lock and its connecting bar in elevation. Figure 12 is a view similar to Figure 1 of a modification, and Figure 13 is a sectional View, wherein the cup shaped end 36* of the screw 36 is illustrated.

- 15 represents a lock case designed more particularly for automobile doors, and 16 is door, and when the window of the door is closed, is accessible only from the inner side of the car.

The bolt 16 is mounted in or on the case 15 which is designed to be secured to the door 21 in the usual and well known manner, and engages a keeper carried by the side 22 of the body of the car,'and is provided with a depending projection 23 adapted to be engaged. by the roll back 24 secured to the hub of the outside lever handle 26. The lug 23 on the bolt is normally held in contact with the roll back 2 1 by the spring 1'7, and the rollback 24 actuated by the handle 26 to retract theboit 16 from the outer side of-the car.

Secured to the latch case is a dead locking mechanism consisting of a dead locking dog 27, a pitman 28 a pin tumbler lock and a connection between the plug of the pin tumbler lock and the pitman 28 for shifting the dog 27 to a position to engage or release the shoulder 30 on the roll back 24. When the dog is in contact with said shoulder, as shown in Figures 1 and 12, the outside handie is absolutely dead locked, consequently the bolt can only be retracted by the inside lever 18. When the dog is moved out of the path of shoulder 30 by the means to be hereinafter described, the bolt 16 may be retracted from the inside of the car by the lever 18, or from the outside by the lever handle 26.

Secured to the lock case 15 is t he plate 31 which, as shown in Figure/ 1, is designed for a large lock, and the pin tumbler lock 32 is located near the edge of the door as shown in Figures 2, 6, 5, 7 and S, and when so located is secured by a screw 36 mounted in a sleeve 33' secured within a hole in the inner edge of the door. The sleeve shown in Figure 2 is provided with one or more peripheral ribs 34 which are provided with milled or knurled pcripheries adapted when forced into the hole in the door, to engage the walls of the hole and hold the sleeve against displacement. This same result can be accomplished by providing the periphery ,making it more difficult to of the sleeve 33 with roughened surfaces as shown in Figure 5. Instead however of roughening the surface of the sleeve the latter may be provided with flanges 35, as shown in igures 7 and 8 having holes for the passage of screws by which it may be secured "to the door. Hi all instances wherein the sleeve is used, the latter is threaded internally for th screw 36' which is prefer ably provided with a cup shaped end 36 to engage ridges 37 on the cylinder 32 of the pin tumbler lock. The cylinder 32 is provided with flattened sides, and it is these flattened sides that are provided with the ridges or ribs 37,'which are engaged by the screws and when so engaged, the cylinder of the lock will be held in place against the possibility of any movement whatsoever. The flattened sides of the cylnder may be parallel as in Figure 2 or they may be at an angle as shown in Figure 6, so that the distance between the that tened sides will be greater at the rear end of the cylinder than at the section taken at the point engaged by the screw 7 thus withdraw the cylinder from the door by violence exerted at the front of the cylinder. The cylinder is of the ordinary pin tumbler type and carries a rotary plug 38 normall held against movement and moved by a key, not shown, dinary and well known manner.

The plug of the pin tumbler lockis provided at its inner end with a pin 40 which rests in a circumferential slot 41 in the sleeve 42 which is secured to the connecting bar 42. The connecting bar passes through plate 31 and carries a hub 43 having a cam 44 which is connected at its free end with the pitman 28. The dog '27 is centrally pivoted to a stud on the plate, 31 and is actuated to engage and disengage the roll back by said pitman.

In some instances it'is desirable to use in the or- .asmsller lock and locate the pin. tumbler lock farther away from the edge of the door and such construction is shown in Figure 12.

In this latter construction the plate 31 which corresponds to plate 31 of the construction shown in Figure 1, extends horizontally lengthwise the lower edge of the lock case instead of vertically, and the pitman;28 is horizontal instead of substantially vertical, thus shortening up the lock case to a considerable extent. This change in the position of the pin tumbler lock is made possible byswinging the cam 44 and pitman 28 to the new position shown in Figure 12,

and is also facilitated by the pin and slot connection 40-41 between the plug of the pin tumbler lock and the connection 42 becc tween said plug and the outside lever handle,

by the pin t-umb ers 39' adjustable in the sleeve and bearin which pin and slot connection also permits of a full revolution of the key plug to about an eighth of a revolution of the deadple and economical and permits of. the necessary operation of the pin tumbler lock and dog which would not be possible without it.

With this construction the pin tumbler lock is supported by the door and not by the. latch or look casing consequently accuracy in boring the hole for the lock is not essential.

It is' evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit of my invention within the scope of theappended claims and hence I would have it understood that I do not wish to confine myself to the exact construction and arrangementof parts shown and described but,

I do not in this case claim the construction of bolt mechanism shown and described,the same being comprehended by my divisional application Serial No. 645,7 96.

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