vl4 Claims.

1 The present invention is concerned with locks of the character or type generally designated as cylinder locks in which a bolt may be projected to a locked position or may be withdrawn to unlocked positionby a manual operation at the inner side of the door and similarly operated by key at the outerside of the door.

Heretofore, in general with locks of the character noted iii-which the bolt is mounted for movement in a tubular housin the locking of the door from-the outside necessitates turning the key a required number of degrees to move the bolt to its locking position and then the key must be reverselyturned back to the position which it started in order that itmay be removed. Similarly, to unlock the door the key is moved a like number of degrees in the opposite direction, thereby moving the bolt to its unlocked position and thenthe key must be returned to its starting position before it can be removed.

The returning of the key to the starting position is confusing to thebperator. Further, since no stops are provided to stop the key at the starting Y position, it has been necessary to locate this position by trial and error and by feeling, which is rather difiicult and in general an annoyance.

Further, care has been required during the installation of the cylinder lock as there is a fixed relation of the parts and during installation they must be put together in accordance with indicating arrows on directions thereon. Unless this fixed relation of parts is made during installation, the installed cylinder lock will not properly operate. The present invention relates to a novel structure by means of which the key may be turned in one direction for projecting the bolt or in the opposite direction for retractin the bolt but such rotation of the key is through a full circle or 360 and further, such rotation is stopped at the proper position in either direction to permit withdrawal of the key. Furthermore, with thepresent invention the manual means at the inner side of the door for operating the bolt may be manipulated in either of its directions without afiectin the key operated means. Installation is simplified as the need for indicating arrows on the parts is eliminated. The structure includes a novel escapement mechanism for effecting ease and certainty of operation, for moving the latch bolt both by manual operation at the inner side of the door and by key operation at the outer side.

It is a primary object and purpose of the present invention to provide a lock actuating structure efiecting the purposes and functions stated, which structure is readily manufactured and assembled, which is sure in use, sturdy and not liable to get out of order, and in which the assembly of the parts and the installation on the door is substantially foolproof, the workman not being required to carefullyabserve and follow certain steps of assembly and operation which, with other cylinder locks, have been necessary.

An understanding of the invention may be had from the following description, taken in connection with the drawings, in which:

Fig. 1 is a horizontal section through a fragmentary portion of a door and associated door casing showing the installation in conjunction with a cylinder lock in plan, with some parts in horizontal section.

Fig. 2 is an inner side view showing the case on which my invention is carried, the key operated bolt retracting and projecting means being shown in end elevation.

Fig. 3 is a vertical section substantially on the plane of line 3-3 of Fig. 2, the key operated structure of my invention being shown in side elevation.

Fig. 4 is a fragmentary vertical section through such key operated mechanism.

Fig. 5 is a fragmentary horizontal section through the structure shown in Fig. 4, said section being at right angles thereto.

Figs. 6 to 11 inclusive are somewhat enlarged elevations of the key actuated mechanism, the end elevation in Fig. 6 being of the assembled unit, and in the successive figures to and including Fig. 11 said unit having successive. parts thereof removed.

Figs. 12 to 18 inclusive are transverse sections intermediate the front and rear sides of the key actuated unit, all of the sections being'atthe same plane, with the parts at the differentpositions which they take during key operation.

Fig. 19 is a fragmentary enlarged partial horizontal section and under plan view on a plane through the unit near the lower side thereof, and

barrel at a predetermined "position.

3 withdrawal by longitudinal movement thereof and when the door is closed, and the bolt pro- J'ected outwardly, it passes through a keeper into a recess in the door casing 5. The door at the opposite sides has openings 6 extending to the interior recess 2. At the inner side of the door a manually operable knob or thumb piece 1,. of conventional structure, is mounted, from which a short bar 8 extends into the interior of the housing 3. The thumb piece I and bar 8 permit manual operation, from the inner side. of the door, of the bolt 4 either to its outer locking posi-' tion or its withdrawn, unlocking position. It is to be understood that the knob or thumb piece I is turned in one direction to withdraw the bolt, and in the other to move it outwardly. The mechanism within the housing 3 actuated by the bar 8, and directly engaged by said bar, may be moved only through a half circle for such projection or retraction of the bolt. The structure thus far described comprises the environment with .which my inventionof the present application is used.

At the outer side of the -door-and covering the outer opening .at 6; is: a housingv 9. The housing-9: is ofa generally oval; form, andwat its ,central'portion has an outwardly projecting part In withinswhich a key operated lock ishoused. Saidlock includes-a. cylinder; or barrel H mounted-within-acasing It. The .zbarrel ll maybe turned about its longitudinalgaxis by akey l2 inserted-therein. From the-casing l3 a wing or vanes extends radially in an upper direction, as-shown. An upper post 15, through which a screwpasses, secures. the housing at the outer side of the door. A fiat plate 16; isplaced thereoverand, attached to said housing. Said plate has tongues H, at its lower edge,,struck and bent outwardlyzat opposite-sides ofthewmg M (Figure 8) for securing saidwing. and, casing I-3 vto said housing 9. It is to be understood that the lockitself', is an. old.and-.well known structure having the .usual tumblers which prevent any rotation of the barrel II when the key, is withdrawn, thekey moving them outward inrecesses made therefor through-the casing l3 and into the wing or vane llzwhen it is inserted in the A lower spacing post 18 is. integral with the housing, through which. aseccndscrew passes in connecting it with theqdoor.

Attthe inner end of the rotatablebarrel H, a plate I29- of a substantially circular form is secured. Theplate L9,, at its central portion and at its outer side, has a projection 20 of, circular outline which seats against theinner end of the barrel ll (Figs.;4=;and,5,). Screws, asshown in Fig. 5, .passthrough'saidiplate l;9- and are threadedinto the. barrel ll. ,Saidplate 19 at the lower. side thereof, asjshown in-Fig. 20, is recessed on two-sides of a downwardly extending, triangular camcr-projection 2|. Two shoulders, equally spaced, from said projection are provided at the outer-sides-of saidrecesses.

A;ring'22 of flat metal has a-central opening of such size that the ring may be placed over thepprojecting portion 20. Said ringis of circular outline except at its lower sidewhere it has a downward; projection. 23 provided with a shoulder ateach side thereof. 'Said ,projection is also formed. with ya vertical slot 2311.: the upper end of which communicates withthecentral open i-ng of marina-.22. A'ring member .24 of thin spring material ,is; provided to be located against theoutergsideof thering 22. Saidrinemember 22 (Fig. '7) and-the parti'25 thereofis located below the lower edge of the projection- 23.

Outwardly of the spring ring member 24, there is provided a plate 26 of fiat, relatively rigid metal. The plate 26 has a generally circular outline except at its upper end where it extends upwardly for a short distance and is formed with two: spaced tongues 21 bent at right angles tothe plane-thereof in an outward direction.

Also around-the periphery of the plate 26, shallow notches 28 are shown and the lower end portion of the plate has a downward extension 29 against the rear side of which the part 25 of the spring ring member 24 is seated. The plate 26 likewise has a central opening large enough indiameter" that the case I3- of thelock may pass through it (Fig. 4). At the lower side of said central opening a tongue 30 is bent inwardly to pass through the spring ringrnember 24 and seat, in the slot 23a of the ring, 22'. When the mechanism ,is installed and in use, the tongues 21 (Figs. 1 and 3) pass, one on each side of the fixed wing or vane l4. Therefore, in all turning'movements of thekey operated barrel ll, said plateZfi and the ring 22-are held against movement. Likewise the spring ring member 24 has no rotative movement but is held in a. fixed relation tov the ring 22 and plate 25 by structure hereinafter appearing.

Againstthe inner side of the circular plate 1-9, there bears a circular flange 3| of a cup member made from sheet metal. The cup'32 of; said member extends inwardly and at its bottom has .a diametrically located slot 33 (Figure 20). Two projections, wings or short tongues 34 extend from the flange 31 at diametrically opposed points and in substantial: alignment with the slot 33. Said cups32 of the cup'member. atone side and. a part. of its bottom,-.and. also 'an inner portion of the flange 3|,iscut away as .showniatflfi. This cut away 35' (Fig.' 5) in the mounting. of the assembled structure'at the inner end of the: barrel H, permits the screws which. are used, to-be passed through said opening at 35, one of them being first passed through andconnected with the barrel H and then the-cup turned through IBOdd'egrees for the passage of'the other-screw use l A flat bar 36, called-a tail piece, having a head 31 at its outer end passesthrough the slot '33, the head coming against the bottom of the cup. Saidbari36'is like thebar 8 in cross section. and is adapted'toenter the barrel3 at the opposite sideofj'bar 8.for engaging the mechanismthereinjfor retracting or projecting the latch bolt. The cup member 32.being,c,onneetedby thebar 36 withthelatch. thus becomes the actuating member therefor.

At the inner sideof-the-fiange 3|, there, is lo cated a.. coupling. member or a ring, 38 of flat rigid metal. At, its. lower side the ring 38 has an. outwardly extending. armor finger. 3,9. struck and bentto extend in an outward direction. The member 38 has a substantiallyellipticalperiphery (Figs. 10 and 11) with a major axis substantially at right angles to the plane of the finger 39, said finger being located substantially at one-endof the minor axis but extending downwardly ashort distance beyond what should be the end of the minor axis of a true ellipse.

The final member or element of structure used comprises a housing having an inner face 46 with housing sides 4| of a generally circular shape extending outwardly. The housing at its lower side is downwardly extended in the same manner that the plate 26 has its U-shaped, lower extension 29, and has sides 4Ia shaped to correspond. -The inner face 40 has a central opening for the cup 32 to pass through (Fig. 5). The member 33 has a central opening of large enough diameter that said member 38 is permitted a limited degree of floating movement. Four tongues 42 extend outwardly from the inner edges of the housing sides 4 I said tongues being spaced so that they may seat in the notches or recesses 28 of the plate 26. The central opening at the inner face 49 of the housing, at one side is notched at 43, so that the heads of the screws connecting the plate I9 to the barrel Il may be passed therethrough for purposes of assembly.

The several parts described, all of which are shown separated in Fig. 20, are assembled within the housing, last described, in direct contact relationship with each other at their adjacent sides, excepting the tail piece 36 which has no contact with any part except the bottom of the cup-shaped member described. When thus assembled, the tongues 42 are all bent inwardly toward each other and against the outer sides of the plate 26 (Figs. 1 and 6), and all of the parts are securely held together, making a compact unit. Such unit, as previously described, is secured by means of the screws shown in Fig. 5 to the inner end of the barrel I I. The lower part 25 of the spring ring member 24 (Fig. '7) is located between the downwardly extending angular sides 4Ia of the housing and is held against rotation.

It is evident that the plate I9 will turn with the barrel II about the longitudinal axis of said barrel upon key operation of the barrel and that said plate I9 is free to move with the barrel I I.

Operation With the parts in the position shown in Figs. 6 to 11 inclusive, and with particular reference to Figs. 8 and 9, the latch bolt has been retracted by turning the key in a counterclockwise direction indicated by the arrow in Fig. 8. The rotary movement of the key is accompanied by a similar continuous movement of the plate I9 since this plate is permanently secured to the barrel I I which the key turns. A stop is provided by the finger 39 coming against a side of the projection 23 as shown, said finger being seated in a recess in the plate I9 at the left of the projection 2| as shown in Fig. 9. Therefore, when in the counterclockwise rotation of the plate I9 the plates engagement with the finger 39 moves the member 38, movement is positively stopped by the finger or arm 39 coming against one end or side of the projection at 23.

- To project the latch bolt to locking position, the parts are rotated in the opposite direction or clockwise as indicated by the arrows in Figs. 12 to 16 inclusive. With such movement in a clockwise direction, plate I9 is turned, moving its projection 2| from the position indicated in Fig. 9 to the left over said finger 39, thus, moving the finger 39 downwardly to the lower part of the pocket or lower extension at Ma of the housing sides 4!, as in Fig. 12. The plate I9 is thereupon freed for a continuation of movement clockwise with projection 39 lying in the right hand recess of plate I I9. Thereupon a continuous turning movement of the plate I9 clockwise, moves finger 39, and the member 38 to which it is connected, with said plate I9. Because the finger 39 rides against the inclined left hand side of the housing walls '4Ia, said member 38 is moved back allowing said finger 39 to move within the circular outline of the fixed guide or housing sides 4|, the initiation of which is shown in Fig. 14. I

The parts I9 and 38 may then be continued in movement in a clockwise direction until as shown in Fig. 15, said finger 39 comes against a side of a wing or projection 34 on the cup member 3|. Such contact occurs after the key and the parts connected directly therewith have moved through substantially of movement. Upon further movement from the position shown in Fig. 15 to that in Fig. 16 said finger 39 carries the projection 34 ahead of it until the finger 39 is brought against the opposite side of the stop at 23. During the latter half of such movement, inasmuch as the cup member is turned, the bar 36 is likewise turned and projects the latch bolt. At this stopping position, after the complete rotation of the key, the key may be removed from the lock. Also this stopping position, when the finger 39 has come against the part 23, at one side thereof, it rides over a rise or hump in the spring ring member 24 (Fig. 19) which hump tends to yieldingly hold said finger and the parts connected therewith against aimless or undesired rotative movement in the opposite or any dir'ection.- Said spring ring member holds finger 39 to allow camming of it by the projection 2 I, and the beveled ends of the projections 34 will engage therewith.

In Figs. 17 and 18, after the parts have reached the stopping position illustrated in Fig. 16, if the key is turned in the opposite direction or counterclockwise, the projection 2I will ride over and push the finger 39 into the lower extension M11 of the housing and out of contact with the stop member 23 thereupon. Except for the interposition of the stop provided by the bolt operating mechanism within the tubular housing 3, a continuation of movement in a clockwise direction as in Fig. 18 would be possible, as the finger 39 has been moved out of the position where it must engage with the stop 23. Such continuation of movement and rotation of the parts first through a complete rotation clockwise, a short reverse rotation counter-clockwise and then a continuous rotation clockwise until stopped permits an assembly of the parts I9, 38 and the cup member 32 and its flange 3I without reference to any exact positions in which they must be placed with respect to the other parts, the key operated mechanism, when disconnected frpm the bolt mechanism being turnable back and forth until the various parts housed between the plate 26 and the bottom 40 of the inner housing member take their. proper positions relative to each other. Furthermore, there is permitted absolute freedom of the operation of the bolt by the manually engageable member I at the inner side of the door in either direction required.

After the bolt has been moved outwardly to its locking position, shown in Fig. 1, and with the parts arranged as shown in Fig. 16, the bolt is retracted by turning the key in the opposite direction. During the first half circle of rotation no movement is imparted to the bolt. After the half circle of rotation the finger 39 engages the right hand side of the projection 34 and thereafter carries the cup member with it, operating the mechanism withinthe bolt housing 3 tov withdraw the bolt. This rotation continues until it is stoppedwby the finger 1 39 coming against the opposite side of projection-Nasshownin Fig. 8.

The bar or tail piece35= by its connection with the bolt -operatesJsaid' bolt either moving to locked orunlockedposition. It isconnected with the cup member 32, which cup member-has the flange 31: and projections 34g-andtherefore moves with it. Theplate 19 is directly connected-to the locking; cylinder which is rotated by the key. The key turns. through 'a-complete revolution and simultaneously therewith the plate I9 is moved through a: full revolutionor 360 It is so designed that the bar ortail: piece 3B,,at times,tis ireen-toi rotate: independently of the; plate: I 9; at other: times, the. plate: i9 may be rotated-without turning; the cup member or the. bar-36 connected therewith; and at. other times said; plate t9 an'd cup-member will be connected together so that they; will turn simultaneously; The escapement mechanism, provides for such movements so that the'bar 36 is rotated about its-axis not more than 180, while the key and the parts directly connected with it; turn through a complete'rotation for bringing thekey: back to the, position at which it: was inserted, stopping: it at suchposition'and thereby providing for its ready removal. The finger39' carried by the ring '38, connects the rotating plate: I 9 with-the look bolt operating-ibar 36* when said: finger isin proper position'to engage the projections 34 and, thusgbecomes "a coupling; member between the driving 1pl-ate'I-9 and; the cup 32. -Howev-er,'-when the'finger3'9-is movedoutwardly of said projections; that'is; into thelateral enlargementA l a of the housingA I the lock bolt operating-barr36 is disconnecte'd'from the plate 19.

In. the operation,,said finger 39 is automaticall-y shifted in positionzwith. the shifting of the ring .38: This shifting of the ring '38 iscontroliedzby the inclined sides of the projection at.'2'l bythe curvature atthe sideedgesor first cams-and-iinnenportions. of the downwardpro-jeotion:23 of the ring 22 above: the stop shoulder,one'ati'eacrredge thereof,..andzi'bythe' inclined sides or cam'surfaces'at'. theendsoflthe projections 34.

- .The bolt'is either fully .projected or fully retracted upon a. turning through of. approximately 180 of movement oi thebolt operating' ban'fl; and" by means of the structureallowing approximately 180 degrees escapement'a. complete-rotation-of the key is provided. -But after-such movement is madein either direction, it is'necessary that "means be provided to force-"outwardly" the finger 39 to disengage the'proj'ections' and bar 39 Should; these be: left in an operatively'connected position to each other, it would be impossible. to rotate the manual lock bolt operating member-"I at'the'inside of the door, because such rotation would be i stopped by. the. locking. action oiQthelockatthe outside of. the-door... Therefore,

toaccomplish thisvthe; plate. l9 has the triangular projection- 2 I The apex of the; projection. .2 l

outwardly into the: enlarged portion-4 l a of the housing 4|.

After the lock has been operated, for example, by the key at the outside,'the finger 39-w-i1l come to rest against the stop at;23 (Fig-1 6,) Immediately before it' comes to this s-t0p,, there is a partial movement outwardly of -the finger. -39 caused by the fingers riding over the rounded or concave side edge 1 of theprojection 23 prion-to coming to the stop. -'A'completion-of this outward forcing of the finger-39 is further accomplished bye; beveled edge of a projection-34 on the flange 3| of: the cap member. This is required in order that the lock bolt may be'operated from the inside of the door. Undersuchcondition the flange 3-l--of the cup member is' turned, and not" the plate l9,: but in: either case, thereis this necessary movement of the floating ring memb'er 38 to force or'cam out the finger '39 to the position shown in Fig. 17.

There is thus provided a mechanism permitting independent movement of the manuallyoperable thumb'member I at the inside of the door, except when the key is inserted in the look at the outside; and" with-a key at the-outsidetherer is: allowed'a; complete rotation through :360wdegrees with an 'escapement. or: lost motion of 180. degrees of its-movement, duringxwhich movement of the lock bolt does not occur. Such mechanism. further providesi'for disengagement after thelBO degrees of effective movement'for'actuatingthelock bolt has. taken; place, *whether done by the manually'o'perab'le; thumbmember I at the insideor by the key on the outside; And further, *such constr-uotion prov-ides forcertainty of" proper installation; not requiring asset relation betweenlcomponenti parts- There is 1 eliminated any need for indicatingtarrows 'or" other? indicia' in the=structure for information to the installer.

With the construction described, the assembly ofithe parts isisimple. and: easy. Furthermore," the installation on the door may be made byany carpenter whether or' not he is 'fami'l'rar'with the lock structure aridits operation- If he turns the housing plate In upside down from the position shown in Fig. 2 it signifies nothing so far as the operation is-concerned, except the key isinserted in -thev barrel H- reversed: from the" position: at which; it would be inserted with the escutcheon and "tumbler loch-right side up. *Ifthe parts house'd'within thehousing wall at'4 t have, for any reasommoved. relative-to-each other;-key manipulation-will take'care oi it withoutany jamming of the parts: and with an automatic" positioning of: them where they should bein. relation to' each other.
