LOUIS W. GATES, OF NEVI HAVEN, CONNECTICUT, ASSEGNOR TO C. UOWLS AND COMPANY, OF NEW HAVEN, CONNECTICUT, A. CBPRATION OF CONNECTICUT.
LOCKING HANDLE FOR 'VEHICLE DOORS.
Application led September To all whom. 'it may concern.'
Be it known that l, Louis W.` GATES, a citizen or the 'United States, residing' at New Haven, county ot New Haven, State ot Connecticut, have invented an improvement in llfockinp]` Handles for Vehicle Doors, oi which the following is a specification.
ln closed cars it is often very inconven ient tor the driver it both the right and left hand doors are litted only with ley locks, as it is necessary in locking the doors to walk all the wayaround the car to lock one of them. For this reason very often the lett hand door is left unlocked or is not even provided with a catch which can be locked, and thefright hand door' only is provided with a key controlled lock. lt is, thereilore, an object of this invention to provide a simple lock which may be easily and `quickly locked and unlocked from the interior ol" the car. Such a lock is especially adapted tor application to the lett hand door as the driver may lock this door before leaving the car and, by locking the right hand door as he leaves the car with the usual key controlled lock, it is leiit secure without the necessity oi' going around to the other side oi the same,
.lt is a further object oi' the invention to provide a lock of this type which may be locked `and unlocked by merely pullingor pushing' on a button conveniently located on the inside of the door. i
With these and other objects in view l have devised the `lock illustrated in the accompanying drawing in which,
Fig. l is a section oi" a portion of a door showing my preferred form of the lock in position.
Fig. 2 is a longitudinal, sectional view of the lock, removed from the door, taken on a plane substantially at right angles to that of Fig. l. l l
Fig. 3 is a longitudinal, sectional view similar to Fig. 2 but showing a slightly modied forni, and
Fig.4 is a rear elevation of the escutcheen.
The door is represented at 10 andis provided with a recess 11 for the usual lock mechanism, not shown. The tace oil the door is usually covered with sheet metal or other suitable means 12, and transverse openings 13 and 14- are provided tor the f90, i921. Serial No. 502,033.
passage ot the lock operating spindle. rThis spindle comprises the usual square lock the escuteheon is rprovided with an 0uti wai-diy extenifling cylindrical hess Qlupon which guard plate is mounted to turn, this plate being' substantially of the same outline as the escutcheon and, when turned to the position shown in 1, is adapted to cover the heads ot' the screws. rFhe lguard plateis provided with a projection 23 adapted to seat in a recess in the stem 16 so that the plate turns therewith when the lock is operated. i y
The escutcheon 19 is provided, around the hearingl tor the stein 16, with a series of notches 24 extending` part way through the escutchcon and leading to anannular channel or groove 25, an annular rib 26 forming the outer wall of this channel. A loclrirng kbar Q7 is mounted to slide in a recess 28 in the stem 1o and is of sufficient length that its outer end 29 projects beyond the surface of the stem 16 and into the channel or -groove 25 when it is slid to its outermost position, as shown in Fig. 1. Wvhen,
however, it is moved to its innermost posiy tion, as shown in Fig. 2+ the projecting end 29 is yadapted to enter one of the notches 24 in -the escutcheon and, as the har '27 is mounted to turn with the stem and spindle, the spindle will be locked against turning, but will he tree to turn when this har is in the position shown in Fig. 1, as the outer end 29 may then more around the channel or groei/e 25. The locking har 27 is moved back and forth in this recess from unlocln` ing to lockingposition by means ot' a rod 30 slidably mounted in an opening` 81 in Jthe stem 16 and a groove 32 extending' longitudinall)7 of the square rod 15 in one side thereof, and having a tree end provided with a button 33 on lthe inside of the door.
ln the slight modification shown in Fig. 3, the rod 30, instead ot' extending in a slot in one side of the square rod 15, is mounted to slide in a central, longitudinal opening 34 therein. ln this form also the stem 16 is provided with an extending elongated slot 35 in which is slidably mounted a locking bar 36 having' its opposite ends projecting from the opposite sides of the stem into the annular channel or groove 25 when the spindle is unlocked. This form gives a double locking means when moved to the locking posit-ion as the locking bar extends into two opposite notches in the escutcheon. This form, however, is more expensive than the form shown in Figure l as it is more diiiicult to drill the central opening 34 in the square rod 15 than to form the groove 32.
The spindle is secured in position in the escutcheon by means of a suitable collar 37 bearing against the inner wall of the eseutcheon and secured on the stem by any suitable means such as set screw 38. It desired, a suitable spring washer 39 may be provided between the guard plate Q2 and the outer end of the boss 2l to prevent rattling of the spindle.
It will be apparent Jfrom the foregoing that this construction provides an effective and simple means iior locking or unlocking the spindle from the inside of the car, as all that is vnecessary is to pull out or push in the bottom 33. Also, because of the guard plate 22 which is mounted to turn with the spindle and handle, when this spindleis locked this guard plate is locked'over the heads of the screws preventing any possibility Q tampering therewith.
Having thus set forth the nature of my invention, what I claim is:
l. A door lock comprising a lool; operating spindle mounted to turn in the door, a stationary member secured to the outside ot' the door, a locking bar mounted in the spindle and adapted for movement to and from engagementwith the stationary member t0 loclr vand unlock the spindle, and means on ythe interior of the door for moving the locking bar to either position.
2. A door loclr comprising a member forming an escutcheon, means for securing thefescutcheon to one side of the door, a lock operating member comprising a spindle mounted in the escutcheon, a locking bar mounted on one side of said member and adapted for ymovement to and from lenga gement with the other member to loclr and unlock the spindle, and a handoperated means on the other side of the door for moving the locking bar to either position.'
3. A door lock comprising an escutcheon, means for securing the escutcheon to one side ot the door, lock operatingjspinrlle mounted to turn in said escutcheon, said escutcheon being provided with a recess, a locking bar movably mounted in the spindle, a rod extending longitudinally of the spindle and connected with said bar, and means on the rod at the other side of the door adapted to move the bar to and from engagement with said recess.
t. A door lock comprising an escutcheon, adapted for attachment to one side of a door, a loclr operating spindle mounted to turn in said escutcheon, said lescutcheon being provided with a recess, a locking bar mounted to slide longitudinally oi the spindle projecting at one end from the side of the spindle', and adapted for movement to and :troni said recess, a rod extending longitudinally of the spindle and connected with said bar and means on the other side of the door for sliding the rod to move the bar to and Jfrom the recess. Y
5. A door lock comprising an escutcheon, a spindle mounted to turn in the escutcheon and provided with a transversely extending recess, said :escutcheon being provided with an annular groove and a recess communicating therewith, a locking har mounted to slide in the recess in the spindle and having a projecting end adapted to extend into the groove or recess in the escutcheon, a rod en tending longitudinally of the spindle and connected with said bar, andmeans on the rod Afor moving the end of the bar into either the groove or recess.
6. A door Alock comprising an escutcheon adapted -tor attachment to a door, a lock operating spindle mounted to turn `in said escutcheon, a locking element mounted in the spindle and adapted tor longitudinal movement therein to and from engagement with the escutcheon to lock and unlock the spindle, a rod extending longitudinally of -theispindle and connected with the locking element, and a handle on said rod at the inner side of the door for shifting the rod and locking ture.
