DOORLATCH SPINDLE Filed Dec. 19, 1932 N VE N TOR FREoER/CK /VoEL RoeERrso/v ATTORNEYS Patented Oct. 24, 1933 UNITED STATES PATENT QFFIC DOORLATCH SPINDLE Application December 19, 1932 Serial No. 647,907
4 Claims.
My invention relates to improvements in door latch spindles which are particularly adapted for use on closed motor cars and the like.
The objects of the invention are to provide means whereby the handle of a motor car door or the like may be so disposed when the door is locked that access cannot be had to it to wrench it off or destroy the lock in order to open the t door to which said handle is axed; to provide such means as will apply to the door having a key lock and also such doors which are not so provided.
The invention consists of a lock or latch spindle and handle wherein the handle is thrust towards the door and into a recess in which it is completely housed when in locked position, and means for restoring the handle to operative position when access to the car is desired by means of a key 0r turn button, as will be more fully described in the following specification and shown in the accompanying drawing, in which:-
Fig. 1 is a longitudinal sectional view of the invention.
Fig. 2 is atransverse section taken on the line 2-2 of Figure 1.
Fig. 3 is a longitudinal section of a modification.
Fig. 4 is a longitudinal section of the release spindle.
Fig. 5 is a transverse section taken on the line 5--5 of Figure 4.
In the drawing like characters of reference indicate corresponding parts in each gure.
The numeral 1 indicates generally the front panel of a motor caridoor, 2 is the rear panel and 3 is a latch or lock casing of any suitable type having a bolt and the usual lugs 4 which are drawn to unlatch the door by the usual latch cam 5.
The numeral 6 indicates generally the lock spin dle which consists of an inner spindle 7 rockingly mounted in the lock casing 3 having a squared end 8 which engages the cam 5 to turn it, the inner end of this spindle is fitted with a projecting key 9 shown in dotted line in Figure 1 and in section in Figure 4, and also an outer portion 10 with which is integrally formed a handle 11. The outer spindle portion 10 is provided with a central bore 12 to accommodate the usual lock cylinder 13 which is adapted, on the key being turned, to retract by means of a pin 14 on the end `ol the lock cylinder a spring operated bolt 15 which is slidably housed in a slot extending transversely of the spindle portion 10. The inner end of the spindle portion 10 is bored concentrically as at 16 and is provided with a longito the limit of its stroke.
tudinal slot 17 in which the key 9 of the inner spindle 7 is engaged to rotatively couple the two spindle portions together. A coil spring 18 surrounds the inner spindle 7 and abuts the lock casing 3 at one end and the spindle portion 10 at 60 the other for the-purpose of thrusting the latter outwardly.
An escutcheon or handle housing 19 is tted to the front panel 1 of the door, whichis provided with a bearing 20 extending through the 65 panel, and an elongated recess 21 into which the handle 11 is adapted to be pushed, the handle when in position within the recess being substantially ush with the top of the housing and filling the recess so completely as to prevent a wrench 70 or other tool being applied to it to turn it.
When the handle is housed within the recess 21, the bolt 15 is in a position to be thrust outwardly from the spindle portion 10 to engage theinner end of the bearing 20, thus preventing the return of the. handle to its outer or normal position as shown in Figure 1.
In the modication shown in Figures 3, 4 and 5, the inner spindle 7 is concentrically bored and journalled Within it is a release spindle 22 hav- 80 ing at its inner end a. handle 23 which is weighted as at 24 or provided with any suitable means for returning the spindle to its normal position as shown in Figure 3, the opposite end of the release spindle 22 is fltted with a circular head 25 35 which carries a crank pin 26 and is adapted to enter the orifice 27 of the spring projected bolt 15 when the spindle portion 10 is thrust inwardly The orice 27 is of such dimension as to allow for the endwise move- 9o ment of the bolt l5 as said bolt passes beyond the confines of the Bearing 20 that it may engage the end of said bearing without moving the crank pin 26, provided the handle 23 is in its depending or normal position as shown in Figure 3. The bolt 15 of the modification as shown in Figure 5, shows the crank pin in a position corresponding to the normal position of thehandle 23.
To operate the device as shown in Figures 1 100 and 3, it suiiices to thrust the door handle 11 inwardly until it becomes housed within the recess 21 of the escutcheon 19, when the bolt 15 slides transversely to project from the spindle portion 10 and engage the end of the bearing 105 20 to retain it in such position, thus preventing any grip being obtained of the door handle 1l.
To release the handle 11 in the device as shown in Figure 1, it sufces to enter the key in the lock 13'and turn it, thus withdrawing the bolt H0 i5 from engegement with the end oi the bear= 2@ end bringing the bolt entirely vvit its slot in the spindle portion l0, the bolt when so withdrawn enables the sp l to exert its effort end flan; 1 the spindle portion 1o and the handle il outwardly so tlmt eccess to the latter cen be obtained to grip end turn it in order thet e. um 1' movement mey be imparted through the key 9 to the inner spindle i end the cam 5, thus operating the door latch to open the door.
To release the letch in the i i cation shown in Figure 3, the upward ing moveent of the hendle 23, through the crenir` pin 26 with draws the bolt i5 into its slot in the spindle por= tion as before described, thus seid spindie portion end the die ii to slide outwardly from the outer rece oi the door.
t li c es my invention is:
1i. i spindle for door locks of motor eers end the like comprising inner end outer telescopic members nonrotstively connected together, one of seid members adept/ed to operatively engage the lock to open it, the other having on operating handle, ineens for extending seid members, ond means ior holding seid members in telescoped position, and means extending through the loch wif-i member to reiense the members from telescoped position. Y
2. A spindle for door iocks or motor cnrs end the like comprising inner end outer telescopic members non-rotstively connected together, one oi seid members adapted to operatively engage the loch to open it, the other he en opereting hendie, e spring i'or extending seid members, end members m hold them in telescoped position, and means for nge@- ing seid venge, means whereby the spring re turns the members to extended position, seid disengaging means comprising e, spindle extending through the lock engaging member.
3. A spindle for door locks of motor cors and the like comprising inner end outer telescopic members non-rotatively connected together, one of said members adapted to operatively engage the loci; to open it, the other having en operethandle, e, spring for extending seid members, end means engaging seid members to hold them in telescoped position, and means for disengeging seid engaging means whereby the spring the members to extending position, seid aging means comprising e spindle extending through the lock engaging member and hsv ing ineens tending to hold the spindle against rotetion.
A spindle for door locks of motor eers end the like comprising inner and outer telescopic members non-rotatively connected together, one of seid members adapted to operatively engage theloch to open it, the other having en operating handle, e spring for extending seid mem= bers, end means engaging said members to hold them in telescoped position, end means for disn engaging seid engaging means whereby the sp returns the members to extended position, seid disengsging ineens comprising a spindle ex teng through the lock engaging member, end being accessible from the side of the loci: remote from the hendle.
