To all whom, it may concern; 1
Be it known that I, Jatrnsll. BANNoornn,
a citizen of the United States residing at' Buffalo, in the county of Wright and State of ldinn'esota have invented new and use ful Improvements inLocks, of which'the I following isa specification.
1 This invention relates to locksand more particularlyto a lockdesigned principally for use on the doors of automobiles and an object of the invention is to provide a lock structure which iscomparatively simple and is operated either by means of a push button or by means of the handlefor the door, and which lock structure is designed to permit the door to be closed and locked without requiring the usualpslamming operation necessary for properly clos ing doors having locks of approved type thereon, such as now commonly in use.
Another object of the invention is to pro-.
vide alock as specified Which maybe locked so that it cannot be unlocked or released by operation of the usual unlockingflmeans.
A further object. of the invention is to provide a lock as specified which includes a pivotally mounted locking pawl adapted to engage and cooperate with a stationary locking wedge to lock the 'doorin closed position, which locking pawl "is moved into locking position by the closing movement of the door and springs into unlocking position under action of its spring upon release of locking means to permit the door to be I Fig. 4 is a view'similar to Fig. 3 showing, the door closed and the, locking pawl in looking position. I
Fig. .5 is a fragmentary vertical section takenon the line 55 of Fig. 2.
Fig. 6 is a detail employed in the lock.
vFig. '7 is a detail perspective iew of the locking pawl employed in the lock. Referring-more particularly to the drawperspectii e of the lock PATENT? oF lc-E.
ings, the improved lock comprises a suitable easing l which niay be inserted into a door A and while the lock is particularly designed for automobile doors it may be usedl in connection with any other type of doorwhere it is foundpractlcal or as found applicable.
The improved lock comprises a locking pawl 2 which is pivotally mounted upon a suitable pivoting pin3. The pin 3iscarried by the transverse plates 1' which are 2 is provided with a substantially V shaped recess 5 in its outer face which faces the opening 6 in the housing 1.' When the door is open and the pawlj2 is in unlocking position the projection 7 is positioned in the path of the locking projection 8 which is carried the plate 9. The plate 9 is in turn carried by the door frame 10.
- When the pawl 2 is in open vor unlocking;
position and the door A'is closed the side 11 of the projection 7' or substantially V shaped opening 5 will be engaged by the locking formed on the housing 1.' The locking pawl projection 8 which will swing-the pawl 2- upon its pivot into the position shown in Fig. 4 of the drawings at which time bot h of the angled sides of the substantially V shaped opening 5 will be in engagement with the angled sides 12 of the projection 8, asclearly'shown in Fig. 4 of the drawings which locks the door closed. When the pawl2 is swung into locked position, the spring 14which engages about a pin 15 on one end of theprojection 16 and about a pin 17 carried by the housing, is tensioned and it is held under tension by means of the upward movement of the locking bolt 18.
The locking bolt 18 is'slidablysupported for vertical movement and it is urged into its upper-position by means of a spring 19.
the horizontal projection or plate 20 which is formed upon the upper end of thelock- 'ing bolt 18. The lockingbolt is provided with a transversely extending recess 21 into .whichis coiled about the pin 3 and engages a which the projection 16 on the locking pawl 11 moves when the locking pawl is in open position, as shown in Fig. 8 of the drawings, however, when the locking pawl 2 is swung into its locking position, the projection 16 will move out of the recess 21 which will permit the spring 19 to flex and move the locking pawl 18 upwardly moving the opening 21 out of registration with the projection 16 which will prevent unlocking movement of the pawl 2 and consequently prevent opening oi the door A.
A guiding flange 23 is struck down from the partition 4: to guide the movement of the lower end of the locking bolt. An operating rod is connected to the plate 20 and exteues upw rdly therefrom extending out or the door i into the interior oi, the vehicle and passing through a suitable guide 25. A thumb nut or button 26 is mounted upon the upper end oi the rod 2 L When the locking pawl 2 is held in locked position by the locking bolt 18 which is, as previously stated at such time in its uppermost position and it i--i esired to unlock the door, downward pressure applied to the thumb nut 26 which forces the rod 24% downwardly which in turn forces the locking bolt 18 downwardly, against the tension of the spring 15) and into the position shown in Fig. 2 of the drawings which moves the transverse recess 21 into registration with the projection 16 and allows the pawl 2 to be rocked and the door A opened.
It the lock is employed upon the door of a motor vehicle oi the closed type, such as a sedan coupe or the like, a handle 27 be provided on the outer side of the door which handle is pivotally supported by means of a suitable support 28. The handle 27 has the end adjacent to its pivot projecting the door into the housing 1 so that upon rocking movement of the handle 27 upon its pivot 30 the locking bolt 18will be forced downwardly to permit unlocking of the door.
It may be desirable at times to lock the door closed so that it cannot be opened either by operation of the handle or by downward pressure on the rod 24L and to permit this looking a locking lever 31 is provided which is pivotally mounted upon the pin 3 and projects through a slot 32 in the housing 1 so as to permit one end of the lever to be engaged by the operator. The end of the lever 31 which is positioned within the housing 1 may be enlarged shown at 33 and it is adapted to be moved into the transverse recess 21, above the door partition plate at so as to prevent the locking bolt 18 from being forced downwardly from operation of either the handle 27 Or rod 24.
It is, of course, to be understood that the invention may be constructed in other manners and the parts associated in different relationsand, there'lt'ore I do not desire to be limited in any manner except as set forth in the claims hereunto appended.
Having thus described'my invention what I claim is 1. A lock comprising a pivotally mounted 70. locking pawl, spring normally urging said pawl into unlocking position, a slidable loching bolt, means normally urging said locking bolt into locking position to lock said pawl in looking position means for moving said locking bolt into unlocking position and permit id pawl to be moved into unlocking POE-HUGH? and a locking lever tor preventing op ration oi said locking bolt bv said last namedimeans. if U 2. ln loch, a pivotally mounted locking pawl. a projection on said pawl. siidablv inoruited locking bolt said locking bolt pro vided with a recess to receive said projection to permit said pawl to more into unlocking position, means for urging said locking bolt into position to move said recess out of regs istration with said projection for holding said pawl in locking position. and means connected to said. locking bolt for moving it to bring said recess in registration with said projection, a pivotally mounted locking lever adapted to be moved intothe recess in said locking bolt to prevent movement of the locking bolt.
A loch comprisin a pivotally mounted locking pawl, a pro ection on said pawl, a slidably mounted locking bolt provided with a transverse recess adapted to receive said projection to permit movement of the locking pawl into unlocking position, a. transverse plate on said locking bolt, a spring engaging said plate andnormally urging the locking bolt into position to move saidrecess out of projection receiving position and for holding said pawl in locked position. and operat-. ing means engaging said transverse plate for moving the locking bolt to bring said recess in registration with said projection.
4. A loch comprising pivotally mounted U0 locking pawl a projection on said pawl, a slidably mounted locking bolt provided with a transverse recess adapted to receive said projection to permit movement oi? the locking pawl into unlocking position a trans verse plate on said locking bolt, a spring engaging said plate and normally. urging the locking bolt into position to move said recess out of projection receiving position and for holding said. pawl in locked position, an opcrating rod connected to said transverse plate for operating said locking bolt, a pi otally supported handle, and a projection on said handle adapted to engage said transverse plate to operate said locking bolt.
In testimony whereof I afiix my signature.
