To all whom it may concern: I
Be it known that T, JAMES F. OBRIEN,
a citizen of the United States, residing at Los Angeles, in the county of Los Angeles,
State of California, have invented new and useful Improvements in Automobile-Locks,
of which the following is a specification.
' This invention] relates to an improved form of lock' for motor vehicles, automobiles,
motorcyclesf bicycles, etc. I herein explain the full application of my improved lock to an automobile; but'iit will be understood that thelock itself is the subject of the present invention, and that the lock may be ap- 15 biles and motor vehicles, etc.; although 1ts 'plied to' uses other thah to locking automoprimary advantages are' most obvious in connection with an automobile.
" There are several prime features which I wish to particularly emphasize, including the -co-axial placement of the tumbler and of the locking disk, the concentric arrangement of themeans for operating the tumbler and disk, the combination of the tumbler and disk and the simple stump and dog combination for holding the disk from move ment;,so that the whole lock'is reduced, to
small size and at the same time its operation is made dependable and efficient.
Another feature of importance is theindependence of the.turnbler and locking disk, to the extent that the manipulation of the tumbler to unlock the lock does not necessarily cause the operation of the locking disk (and' does not cause the unlocking of the hood). This is'fully explained hereinafter. 1 have illustrated a preferred embodiment of my ings, in which,
Figure 1 is a longitudinalsection of'my improved lock, is a section taken as indicated by line 2--2 of Fig.1, Fig. 3 is a section taken as indicated by line 33 of Fig. 1, Fig. 4 is a view illustrating the application of my lock to an automobile, F ig.
5 "is a view showing the'hood locking means.
Til the drawings, the" numeral 10 niay'designate the dash of an automobile, and. 11 may designate the casing ofmy lock mounted thereon, the "dash forming the forward part of the casing. This casing 11 has a central wall or web 12with a bearing13 at its central part, this bearing 13 carrying the hiib 14: of the flat disk tumbler 15. This flat disk tumbler 15 is of a type well known to-the-art, its rear face having various ribs nvention in the accompanying draw 16 thereon of different shapes,
cams to shift the stump pin 17 stump lever 18.betwee n the positions shown in full and dotted lines in Fig. 2. Rotation of the tumbler 15 is accomplished through the medium of a shaft 20 extending rearwardly from a thumb disk 21 which projects from the dash 10. This thumb disk 21 may carrya disk 22 having notches 23 in its periphery, a flat spring 24 engaging these notches to form a clicker to indicate the rotation of the tumbler 15. When the tumbler 15 has been rotated back and forth in a pre-determined manner, the stump lever acting as 18 will be forced to the position shown in dotted lines in Fig. 2. The stump lever is mounted upona shaft 25, which shaft also carries a dog 26. This dog 26 is adapted to engage against a shoulder 27 on the rotatable locking disk 28 to prevent movement of the diskin the direction indicated in Fig. 3, which disk is mpunted with its hub 28 upon the outside of the bearing 13 carried by .web 12. The disk 28 and the tumbler 15 are co-axial. A hollow sleeve 29 engages the disk 28 on its inner end and carr 1es on its outer end a manually engageable handle 30 depending below the thumb disk 21. The sleeve 29 is flattened or otherwise formed for engagement with the disk 28 so that the disk and sleeve must turn together. See Fig. 3. When the dog 26 has been moved to the position shown in dotted lines in Fig. 3, then the locking disk 28 may be turned in the direction indicated by turning and. the
the handle 30. But it willbe understood that themanipulation of the tumbler does not directly cause or necessitate movement of the locking disk. Removal of the dog tion the rods 31 take to reach the hood lock- I ing mechanism. Stop 31 may limit the movement of the locking disk in the direction opposite to that indicated; although it will be seen that the rods 31 throw over against the hub 28 and form eflectual stops to thedisk movement.
mounted upon longitudinal shafts 36, which.
are operated by the connecting rods 31. The lower edges of the hood may be guided to correct position and prevented from moving outwardly by suitable stops constructed, as is best shown in Fig. 5, with plates 36 with upturned edges 37 secured to the frame of the automobile by bolts 38. The upturned edges bear against the sides of the bolt heads to prevent the bolt heads being turned without also turning the plates 36;
and when the hood is locked down the plates I 36 cannot be turned owing to the engagement of the hood. with their upturned edges 37. It will thus be seen that the hood cannot be opened unless the lock is manipulated according to the correct combination, which can only be done by authorized persons. But the hood need not be unlocked unless so wished. It will be noted that the rods 31 extend in such directions that their pull on the-studs 31 tends to rotate the disk 28 opposite to the direction indicated; that is, the studs 31 throw over center with respect to the pull on the rods 31. So that, when the dog 26 is retracted, there is no tendency for the disk to move in the direction indicated unless the handle 30 is moved. The lock may be manipulated (by an authorized person only) to connect the ignition. circuits without loosening the, hood look. This provision makes it possible to do awaywith all the usual devices for holding down thehood,
. my device completely supplanting them. I
.provide also cert'aimswitches which control the electric ignition of the engine which is locked under the hood. The general arrangement of these switches in the ignition circuit is not necessary to be herein described; I particularly describe the switches in their combination with my lock mechanism. There is one switch which comprises a contact base 40 adapted to be engaged by the lever 18 when in one of its positions, this being a switch which will ground a cur rent on the wire 41 when the lock is in the proper correspondingposition. I also provide a switch which makes and breaks the circuit between "two wires 42 and 43. This switch may comprise a sliding contact piece l4 connected at 4:5 with the lever 18 and in normal engagement with the contact 46. Movement of the lever 18 causes movement of the end 44 of contact 4% into engagement with the contact 47 completing the circuit between wires 42 and 4:3. The frictional engagement of the lever 18 with these switches, and the friction of the moving contact 44 with the contacts l6 and 47, is sulficient 13L hold the lever 18 and the dog 26 in any position to which they are moved by the action of the tumbler. The switches thus perform a function which is usually performed by a spring or other member bearing against the lever 18. -T he switches are connected into the ignition circuit of the engine 33 in such a manner that when the lock is locked (the lever 18 being in the'position shown in full'lines) no current can be obtained for ignition of.the engine charges. At the same time the hood is locked down so that it is impossible for an unauthorized person to reach the wiring system covered by the hood to tamper with it. The machine is thus securely and positively locked against theft.
1 herein explain the application of my lock to an automobile in order to most clearly point out its advantages; in the following claims I particularize on the improvements in the locking mechanism. It
is broadly immaterial what work the lock- I ing disk 28 does; it ay Operate locking mechanisms of any character, although, as explained, it is particularly adapted for the functions described.
I claim- I 1.
