KEY LOCK.
Application iled February 7, 1923. Serial I-To. 617,584.
vnew and useful improvements in a Key Lock, of which the following is a specification.
The present invention relates to a ley lock oi' the cylindrical form adapted to be inserted through a door 'for operation oit a latch and has for its principal object to provide a simple and e-iiicient mechanism Jfor holding the proper Key within the loch: while it is being operated and preventing any but the proper key being utilized for turning the lock s0 as to operate the latch assoc-lated therewith.
A further object ot the invention is to generally improve upon locks ot this nature by providing a device which is comparatively inexpensive to manuiacture` one which is reliable in operation and well adapted to the purpose for which it is dcsigned.
Vilith the above and numerous other objects in view as will appear as the description progresses, the invention resides in certain novel features or" construction, and the combination and arrangement of parts as will be hereinafter more Fully described and claimed.
In the drawing Figure 1 is a longitudinal section through the lock embodying my invention Figure 2 is a transverse section taken therethrough substantially on the line 2-2 oi' Figure 1,
Figure 3 is a similar view showing the lock partially turned,
Figure 4f is a detail perspective of the tumbler.
Figure 5 is a plan view of: the base oi the tumbler, and
Figure 6 is a fragmentary plan view oit the key for operation oi2 the lock.
Referring to the drawing in detail it will be seen that. a cylindrical casing 1 is con structed with a longitudinally extending interior groove 2. A cylindrical blocs 3 is rotatable within the cylindrical casing 1 and is provided with a longitudinally extending channel 5 which is comitructed with a pair 'ot ojiipositely disposed extensions f1 and a pair ot recesses G one in each extension ot the channel 5 and slightlyspaced from the channel and preferably being locatedmidway between the ends ot the block 3. Disposed within the longitudinally tending'channel 5 is the tumbler indicated generally at Zi. rlhis tumbler consists of an elongated block body 8 having ears 9 at its ends suitalgily recessed as at 10 for toi-nn ing seats to receive trunnions 11 extending from the ends ol roller 12. A pair of lugs 13 extend laterally from the surface of the block bodyS adjacent the roller 12, one cxtending beyond each side thereof' so as to engage compressible coil springs ifi disposed in the recesses 6 and to move in extensions 1-. Thus it will be seen that the tumbler is nor mally positioned in raised or separated association with the bottom lof the channel 5 when the roller 12 is disposed in the groove j ilurality ot pin projections 1G extend from the base oil the tumbler A on the blockbody 8 thereof and when the roller 12 is in the groove 2 the terminals of these pin projections 16 are spaced from the bottoni ol? the channel. 5 so that a key 17 may be inserted in the channel.
This key 17 which is disclosed particularly in Figure 6 is provided with a plurality of apertures 18 disposed in coincident arrangement with the pin projection 16. Thus the key 17 may be inserted in the channel ot the block and by turning the saine with the hey the block 3 may be turned within the cylindrical casing 2 thereby causing the roller 12 to leave the groove Q and depress the tumbler and at the same time causing the pin projections 16 to pierce the apertures 18 so that the lrey cannot be removed troni the block until the roller is again engaged with the groove 3. lt is also evident that only a hey having its apertures in coincident arrangement with the pins 16 can be successfully used for operation oit the lock,
rlhe forward end of the cylindrical. Casin is provided with the usual cover plate 19 having an openinoj 2O therein so that the key may be inserted therethrough ttor insertion in the channel 5. rllie key 17 is constructed so as to protrude through the end et the block wien inserted the ein for cngageinent with any suital le latch mechanisni. It will readily be seen that tho loch thus torn is durable, reliable., and of conn iarative simple construction. rlhe lock also has the advantage oi? readyaccessibility to the parts thefeoitl se that it may be nascar bled and disassembled with comparative case whereby the cost of repairs may be minimized as Well as the costof the initial manufacture of the device.
Although I have described the device with a certain degree of particularity it is to be understood that numerous changes in the details of construction and in the combination and arrangement of parts may be resorted to without departing from the spirit of the invention as hereinafter claimed.
Having thus described my invention, what I claim as new is z- 1. In a lock of the class described, :i ing, a block rotatable in theczising and provided With a channehzi tumbler slidub-e in the channel and provided with projecting pins extending toward the bottom ot' the channel, zt key insertuble in the chunnel hirving apertures therein to receive 'the pins, said casing providedk with a groove, a roller journaled on the tumbler, and spring means normally holding the tumbler in e position whereby the roller engages the interior ot the casing, said pins piercing the apertures of the key when the roller is out olf the groove of the casingr and vice versa.
2. In u lock of the class described, :i eylindricel easing, s, cylindrical block rotiitable in the casing and provided with :i hit portion, :i channel evtenilinp,r longitiulinully ot' the lint portion, sziid block provided with recesses one on euch side of the channel opening` into the flat portion, :i tumbler slidable in the channel :ind provided with lugs extending over the recesses, eonipressible coil springs disposed in the recesses for engagement with the lugs thereby holding the tumbler in :i raised position in the recess, said casing` provided with u longitudinally extending' groove, u roller journaled on the tumbler for eilffugenient with the `groove :ind the interior oi" the easing und nieiins on the tumbler for engaging u key inserted in the channel when the roller of the tuniber is out of engagement with the groove ot the easing.
In testimony whereot- I uflix niy signature in presence of two witnesses.
