William J. Daningburg, Stamford, Conn., assignor of one-fourth to Paul Mulnard, Ridgewoofl,
Refiied .for abandoned application Serial No. 574,553, November 12, 1931. This application April 14, 1936, Serial No. 74,281
6 Claims.
i This invention relates to a new and useful improvement in an automatic automobile door catch and lock.
This application is a refile of my original ap- 5; plication filed November 12, 1931., Serial No.
The invention has for an object the construction of a catch lock, which is characterized by the provision of pivotal handles on the outer and 10;; inner sides'of the door and capable of operating the bolt of the lock. 7
. vAs another object of this invention, it is proposed to arrange a key look upon the door in amanner so that its bolt canrestrict the pivoting of the handle on the outer side of the door, for the purpose of preventing opening of the door lock iromthe outside. r 7
Furthermore, this invention contemplates means a-ssociated with the handle on the inside Qf ;i.',he door for holding the door lock opened, or for .locking the look so that it cannot be operated by the'hand-lejon the outside of the door. The invention has for a still further object the construction of an automatic automobile" door catch and lock, which is of simple, durable construction, desirable ,in use .and efficient inaction, and .which may be manufactured and sold at a reasonable cost.
..-For further comprehension of the invention, and pf the objects and advantages thereof, references. will be had to the following description andaccompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawing forming a material part of this disclosure: 1
Fig. .1 is a fragmentary elevational view of a door provided with a lockaccording to this inventiongzand viewed from the outside. I Fig. :2 is a fragmentary enlarged sectional view taken on the line .2--2 of .Fig. 1.. Fig. .3 is a. sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is an elevationalview looking in the direction-of the arrows 4-'4 of Fig. 2. '5 Q'Ihe reference numeral I indicates a door which is capableof closing against a door j'amb 11. The door is provided with a catch lock which includesa retractible bolt I2, capable of engaging' in' akeeper 13, mounted upon. the jamb .I.I. l.A recess 14 is formed in thejamb -I II, to betteraccommodazte the :boltIZ inits extended position, 55 alhe lock upon the. door consists of a hollow casing I5. The casing I5 extends through the door, so that it has a face exposed on the out side, and another face on the'inside of the door. A disk I! is rotatively mounted within the casing. The belt I2 is pivotally attached at its 5 inner end IB, upon the disk H.
A pair of rods I9 is pivotally mounted upon the disk I and slidably supported by standards 20. One of the rods 19 is adapted to extend from the front face of the casing I5, and the other from the rear face. 7
The lock-26 is mounted upon the outer face of the door l0, and. is provided with a bolt 21, capable 'oiextending behind the cam 23, so as to restrict swinging oi the outer handle ZI. The details of this lock not be given, since any conventional lock may he'used which has an extendable bolt. The handle 24 on'the inside of thedoor, addition. to being pivotally mounted, is also slidablycmonnted upon its supporting pintle pin.28. Resilient means in the form of a spring v29 coaxially upon the pintle pin 28 serves to urge the handle against one of the lugs 22. A bottom'stop 3.8 projects from this .lug and limits downward motion of the handle to the vertical. Asecond stop 31 projects from this .lug 22, and limits the upward motion of the handle to :the horizontal.
. A- finger 32- profiects irom the cam 23 of the handle upon the inside of the door, and is capable of. passing through an opening in the adjacent rod 19., when the handle ;2:I is pivoted further backwards than allowed by the stop :39. Such pivoting is-possible by first the handle 21 laterally againstxthe action of the spring 29,50 that itmay'rpass the stop 30. When released, the spring 29 urges therhandle back against the .lug, sothatit may maintain its new position. In .the new pivoted position, the finger .32 engages in the the outside of the door can opening 33, and latches the rod l9 against motion, to prevent turning of the disk I! by operating the handle 2| on the free side of the door. The opening 33 must be of sufiicient size to allow engagement by the finger 32, eventhough the handle 2l is movedlaterally. 1;
The operation of the catch lock may be understood by assuming it in the condition illustrated in Fig. 2. The bolt I2 is shown in the keeper l3, the bolt 21 is shown to prohibit. operationof the V outer handle 2!, and the other handle 2! is'free 1;
to be moved. In this condition, a,person from j cause opening of the look. A person from the inside may 'move the handle 2!, to cause retraction of the bolt l2,
so that the door may be opened. If'the lock'26 is operated so that the bolt 2-1-isdrawn in,then the handle 2! on the outside of the door can be oper-' ated to cause its cam 23 to depress theirod--l9-, which, in turn, causes retraction of the bolt I2, I
and the boltl2 is retracted.
It is to be underst' odthat while my invention is described to'be an automobile doorlock, it may be equipped onany house, garage or other doors.
While l have described my invention with some degree of particularity, lrealize that in practice various alterationstherein may be made. I'therefore reserve the right and privilege of changing the shape of the'h'andle'a'nd 'the' form of all other details or otherwise altering the arrangement of r the correlatedparts withoutdepar'ting from the spirit or the scope of the appended-claims.
Having thus described m'y in've'ntion, what I claim as new, and desire' to secure by'United States Letters Patent is:
