can noon Locx hpplication'filed November 4, 1929, Serial- No. 404,636. Renewed June 6, 1931.
My invention relates'to improvements in f verticalinner plate 8 with which the casing '11 is provided,F igs. "1, ,3 and '6. 'The outer wall ofthe casing 1 has a smooth hole'through which the screw 7 extends. The plate .8 has car door locks. It relates particularly to locks of automobiles in which the doors close against jamb seats.
One of the objects of my invention is to provide a door lock of the kind described with novel means for forcing the door of an auto mobile toward the open'position, when the door handle at the inside of the door is operated to retract the bolt, thus making a close to get out of order, and which can readily H be adapted to car door locks of the types in common use.
The novel features of my invention are r hereinafter fully described and claimed.
In the accompanying drawings, which il- 1 lustrate the preferred embodiment of my invention,
Fig. 1 is a side elevatlon of a lock provided Sufliciientlost motion is provided to permit thebolt' 3 to be fully withdrawn before the with my improvement. 4
Fig. 2 is a sectionon the line 2-2 of Fig. 1, showing the door fully closed, the bolt engaged with the jamb, and the push screw retracted to the inactive position.
Fig. 3 is an enlarged bottom view of the lock, portions thereof being omitted.v
Fig. 4 is a. View similar to Fig. 2, the door bolt being retracted, the push-screw projected, and the door partlyopened.
Fig. 5 is an enlarged section on the line 55 of Fig. 2.
Fig. 6 is a section on the line 6-6 of Fig. 5. Similar characters of reference designate;
similar parts in the different views.
fitting door easy to open from the inside of handle 4 is swung to retract thebolt 3, said ffhe doo'r will thus be partly opened by the screw/{pushing against thejjambseat 5.
When the doorisclosed and the handleis v 1 designates a lock casing of usualtype shown mounted on a car door 2 and having U through. it a transverse hole provided with a circulartrow of recesses 9 in which the threads 10 of the push screw are slidably fitted. j v V :VVhen the screw 7 is turned in a counter to clockwise direction, as Viewed in Figs. 1, 2,
"5 and 6, it-will move through the plate 8 so as to" project from the casing 1, as shown in- Fig 4, andin so moving it will push against the seat 5 of the jamb 6, thus, the bolt 3 being retracted, forcing the door 2 toward the open I, position, and making it easy for the operator within the car tofully'op'enthe door. j v
For so turning the push screw when the screw 7' has a crank arm 11 to which is pivot-v ed one'end of a link 12, the other end of whichis pivoted to a crank 13 mounted on and .oscil'lative with the handle 4.
" In the :operation, the operator in the car s wings the handle 4 to retract the bolt 3 from Y j the j'amb 6,. and in'such morement' of the handle, the crank 13, link 12, and crank arnr 11 turn the screw 7 to'the position shown in 1 returned to its original position, shown in Fig; 1,the" crank 13, link 12' and crankarm 11 will retract the screw 7 inwardly to the position shown-in Figs. 2, 3and 6.
A small openingmovement ofthe door by 1 the push screw 7 is sufiicient to permit'the operator toeasily open thedoor the rest of the way.
I do not limit-my invention tothe structure shown'and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of. my invention.
What I claim is 1. In a car door lock, the combination with a door lock having a lock casing, a handle, and a bolt retractible by said handle, of a push member oscillative in and having threaded engagement with said casing such that when turned in one direction it will project from said casing and adapted to push against a door jamb so as to open a closed door adapted to carry said lock and cooperating with said jamb, and means actuated by said handle, when the latter is operated to retract said bolt, for turning said member in said direction to the pushing position.
2. In a car door lock, the combination with a door lock havin a lock casing, a handle, and a bolt retractlble by said handle, of a push member oscillative in and having threaded engagen'ient with said casing such that when turned in one direction it will project from said casing and adapted to push against a door jamb so as to open a closed door, adapted to carry said lock, said push member having a crank arm, a crank on said handle, and a link connecting said crank and said crank arm, for turning said push member in said direction to the pushing position, when said handle is operated to retract said bolt.
8. In a car door lock, the combination with a door jamb having a seat, a door cooperating with said seat and having a lock having a casing, a handle, and a bolt retractible by said handle, of a push member oscillative in and having threaded engagement with said casing such that when turned in one direction it will project from said casing and adapted to push against said seat so as to open said door, and means actuated by said handle, when the latter is operated to retract said bolt, for turning said member, in said direction.
4. In a car door lock, the combination with a door jamb having a seat, a door cooperating with said seat and having a lock provided with a casin a handle, and a bolt retractible by said handle, of a screw having oscillative threaded engagement with said casing, and when turned in one direction projecting from said. casing, and adapted, when so turned, to push against said seat so as to open said door, and having a crank arm, a crank on said handle, and a link connecting said crank and said crank arm, for turning said screw in said direction when said handle retracts said bolt.
In testimony whereof I have signed my name to this specification.
ROBERT N. SMITH.
