This invention relates .to locks and refers more particularly to automobile door iocks of the type known as pillar locks. The characteristic feature of a pillar lock resides in the provision of a driving or eperating shaft which is coupled with tniqck'eyunder and projects axially rearwardly therefromte transmit rotation of the cylinder to'a door latch mechanism to be actuated. In mostiristances it is very desirable'to so' connect the lock eylinder with the driving shaft as to afford the shaft a limited degree of universal motion to'thus enable it to compensate for misalignment betw en the loci; casing and the latch mechanism on U he door Y v H Relatively simple connections between the driving shaft and the lock cylinder'haveheretofore been devised which embody provision f 'or such universal motion, "but'the' "drive shafts' o'f sueh structures have'her'etofore had to be fabricate b other than a stamping operation since w 4 relatively complex in shape'and cguld not be formed as a flat or strip like'memben ample of the previous'type of driving shaft'of this character is to be foundinthecopending appl tion of Edward N. Jacobi, Serial'NQYlIb QQZ filed September 3, 1949, now Patent' llo 2,6 0 5", 6 3'1.
It is therefore an object'of this inven on to provide a pillar lock having its driving shaft fabricated as an extremely simple and inexpensive stamping but nevertheless providing a connection between the driving'shaftand the loci; cylinder which affords a degree of universal motion to the driving shaft.
Another object of this invention resides the provision of a pillar lock havmge universal ieint connection between the lock'icylinder and the driving shaft and wherein the portiori'of the connection associated with the lock cyl'inderinay be formed as a very simple'die' casting whieh is' in} tegral with the lock cylinder and does not ne V seitate complicated coring;
A further object of this invention is to provide a connection between the driving shaft and'th'e lock cylinder of a pillar lock wmeneonne tibi; will be held operative by means of a coiled pring which also serves to bias the lock cylinder to its neutral or key-receiving position of rotation."
Still another object of" this inventio'n resides in the provision of a pillar lock having a connection between the lock cylinder and the driving shaft whereby the shaft will be yieldably held coaxial with the cylinder, extending straight rearwardly therefrom, to facilitate its installation; but W l b c pable f a mited degree. of universal 2 motion, to thus compensate for any misalignment between the lock mechanism and the latch mechanism to be actuated thereby.
Another object ofthis invention resides in the provision of a pillar lock in which the lock cylinder is held against axial displacement by means of a bayonet connection and'in which rotation of the lock cylinder to a position at which the bay- I chat connection becomes disengaged is precluded by means of apart of the'driving shaft.
'W-ith the above and other objects in view which will appear'a s thedes'cription proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described, andinore particularly defined'bythe appended claims; it being understood that such' changes in the precise embodiment of the herein disclosed invention may be made as come within'the scope of the claims.

Figures 9,-1.0 and 11 are rear .views of a portion of the lock casing with the cylinder therein in the several successive positions which it occupies during its assembly into the casing.
Referring now more particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views, the
der mechanism 1 is rotatably received. The lock meme 3 cylinder mechanism may be of any conventional type, that illustrated being the well-known side locking bar type which is freed for rotation upon the insertion of a key 8 therein. The key receiving slot in the lock cylinder is, of course, accessible at the front of the casing and may be covered by a dust cover 9, if desired, to preclude the entry of rain and foreign matter into the lock mechanism. The casing may be mounted in a door handle or on the lid of an automobile rear compartment in any suitable manner, and for this purpose is provided with radial ears Ill or other appropriate mounting means.
Rotation of the lock cylinder is transmitted to a latch mechanism (not shown) by means of a driving or operating shaft H. tion between the lock cylinder and the driving shaft comprises an axial rearward extension l2 at the rear of the lock cylinder having a rearwardly and laterally opening cavity l3 in which the front portion of the driving shaft is received. This extension is integral with and thus comprises a part of the lock cylinder, and the front portion of the cylinder, comprising the lock mechanism, will be referred to herein as the cylinder body.
As best seen in Figure 7, this extension is substantially coaxial with the cylinder body and has a smaller diameter than the cylinder body to thus define a rearwardly facing shoulder M on the rear of the lock cylinder body. The cylinder is insertable into the casing bore from its front, in a manner to be described presently, and the shoulder I4 cooperates with a circumferential rib l5 which extends part way around the bore of the case, at the rear thereof (see Figure 6), to preclude axial rearward displacement of the cylinder out of the casing.
Axial forward displacement of the lock cylinder out of the casing is prevented by a bayonet lug l6 which projects radially from the extension on the lock cylinder and has its front face I! spaced from the shoulder [4 a distance equal to the width of the rib l5. Since the rib extends only part way around the circumference of the case bore, it will be seen that the rib and the bayonet lug l6 cooperate to define a bayonet connection between the lock cylinder and easing. As will be later described in greater detail, after the lock cylinder has been moved into its assembled position in the casing, defined by engagement of the shoulder l4 with the front face of the rib, establishment of the bayonet connection involves rotation of the cylinder in one direction (counterclockwise as seen from the front of the lock in the embodiment illustrated) past the free end l5 of the rib to engage the lug over the rear face thereof.
A stop lug l8 projects rearwardly from the back of the case at the other end of the rib, and one of the longitudinal faces l9 of the stop lug cooperates with a face of the bayonet lug 16 to define the limit of counterclockwise rotation of the lock cylinder.
As will be seen presently, the other longitudinal face 2| of the stop lug l8 cooperates with a part on the driving shaft to provide a stop defining the limit of clockwise rotation of the lock cylinder to preclude its rotation to a position at which the bayonet connection is disengaged.
The lock cylinder is biased to its counterclockwise limit of rotation, which constitutes its neutral or key-receiving position, by means of a coiled torsion spring 26 which surrounds the extension 12 and the front end portion of the driving shaft The connec- .4 l I to thus also retain the shaft in position in the cavity I3 in the extension.
The spring comprises several concentric loops of steel wire. Its end portions are bent into an outwardly curved hook 21 and an inwardly curved hook 28, on its front and rear loops respectively. An arm 30, extending rearwardly from the case, has a hook 3| at its rear end, and the outwardly bent hook 21 on the spring engages therein, while the inwardly bent hook 28 at its other end engages around a tit-like lug 32 on the rear of the extension [2. The hook 3| on the case and the tit-like lug 32 on the rear of the cylinder extension are circumferentially spaced at opposite sides of the lateral opening of the cavity so that the torsional tension of the spring also tends to draw it toward the side of the cylinder extension to which the cavity opens.
' Short flanges 35 at the rear of the extension, adjacent the rearward opening of the cavity [3, provide forwardly facing shoulders against which the rearmost coil of the spring engages to preclude rearward displacement of the spring. These flanges, together, extend only part way around the circumference of the extension, to enable them to clear the rib 15 as the lock cylinder is inserted into the case, as will be explained in detail hereafter.
The driving shaft II comprises a fiat substantially L shaped member which may be readily fabricated as a stamping. The stem 23 of the L extends rearwardly from the extension toward the latch mechanism to be actuated and is normally held substantially coaxial with the lock cylinder, but it is obviously desirable that the connection between the driving shaft and the lock cylinder be such as to permit the rear of the shaft to swing in any direction to a limited extent to compensate for any misalignment between the lock mechanism and the latch mechanism to be driven thereby. To this end the connection between the driving shaft and the lock cylinder comprises a slot or cavity 13 in the extension on the lock cylinder, which cavity opens to the rear and radially to one side of the extension and in which the front end portion 25 of the driving shaft, comprising the cross member of the L, is received.
The longitudinal or side walls 37 of the cavity are spaced farthest apart at the rear of the extension and converge forwardly, being substantially parallel to one another at the front of the cavity, where they are spaced apart a distance slightly greater than the thickness of the driving shaft, so that the front portions of the' cavity side walls constrain the driving shaft to rotate with the lock cylinder; The divergent rear portions of these walls (best seen in Figure 2) enable the driving shaft to be rocked flatwise from ,side to side. The bottom Wall 38 of the cavity is substantially straight and parallel to the lock cylinder axis, as best seen in Figure 8, and since it is normally engaged by the straight adjacent side edges of the shaft, the latter is held in a position in which its stem extends straight rearwardly from the lock cylinder, the depth of the cavity being such that the center line of the stem substantially coincides with the axis of the lock cylinder when the, driving shaft is in its normal position.
The front end portion of the driving shaft is deep enough to project radially out of the cavity a substantial distance, and has a shallow slot 39 in its projecting portion, the bottom of the 'slot being parallel to the axis of the shaft and asss ozs its axial T length being =such as to snugly accommodate the coils of=the-spring 26. The front of the slot defines a rearwardly facing shoulder 4|]. which engages against the front'coil of the spring to preclude axial displacement of the driving shaft out of the'slot.
Since the spring surrounds the extension and lies across the driving shaft, in the slot'39 therein, radial displacement of the shaft out of the cavity is also blocked by the spring, although its resilience permits the above described swinging motion of the shaft. In this connection it will be noted that the extension has a reduced diameter in the neighborhood of the cavity opening to enable the spring to seat firmly in the bottom of the slot 39 in the driving shaft. Itwill also be observed that the stop lug l8 has its rear end notched, as at 4|, to clear the'spring and to provide a ledge 4| which overlies the spring 'to-steady it to a certain extent.
A forwardly extending foot 42 on thefront portion of the driving shaft overlies a ledge 43 on the extension, immediately behind the shoulder M on the lock cylinder body, and engages the ledge to limit edgewise swinging motion of the shaft about the transverse bottom wall of the cavity as a fulcrum (in the direction indicated by the broken line in Figure 8) to thus prevent the shaft from'being cocked to a position in whichthe front coil of the spring can ride up the lock.
The radial projection on the shaft which defines the shoulder 40 and which carries the foot '42 also serves as-anabutment whichcooperates with the face 2lof the stop lug opposite to that engaged by the bayonet lug to define the limit of clockwise rotation of the lock'cylinder and thus prevents rotation of the cylinder to a position in which the bayonet connection between it and the case is disengaged.
Assembly of the lock of this invention is extremely simple. The-cylinder is inserted at the front of the case with the flanges 35 at the rear of the extension held in the position shown in Figure 9 relative'to the case, i. e; out of alignment with the rib 15 so as to clear the same as the cylinder is moved rearwardly. As the cylinder is inserted'into'the case in this position,
the bayonet lug It eventually engages the front face of the rib l5,'and at this point the cylinder is rotated clockwise (as viewed'from the front) to enable the bayonet lug to be passed .around the free end of the rib. The'cylinder may then be moved rearwardly until the shoulder M on the'rear of the cylinder'body engages the front face" of the rib, after which the cylinder is rotated counterclockwise to'engage the bayonet connection. It'willofcourse be understood that the key is left in thecylinder during this operation to retract the sidebar of the cylinder and to facilitate rotation thereof. Next, the front portion of the driving shaft is slipped into the cavity and the 'ends of the spring-are then hooked into place on the lug 32 on the extension and the hook 31 on the arm 30, respectively, tocomplete the assembly of the lock.
From the foregoing description, taken together 6 with the accompanying' drawings, it will be readily apparent'that this invention provides an unusually s-imple pillar lock having a driving shaft-which is connected with the lock cylinder in a manner-providing a degree of universal motion, tothereby accommodate any misalignment between the lockandlatch mechanism to be actuatedthereby. "lt will also be seen that the lock-of this invention is extremely inexpensive to manufacture by reason of-the fact that the driving shaft may be=fabricated as a stamping; because both the casing and-the cylinder may be "made as-relatively simple die castings which do not involve complicated coring; and also becauseassembly of the lock may be very readily accomplished without special tools.
