LATCH.

Application filed ctober 24.-, 1921.

T 0 all whom. t may concern.

Be it known that I, LEON OTTINGER, a citizen of the United Sta-tes, and a resident of the city of New York, county and State of New York, have invented a certain new and useful Improvement in Latches, of which the following is a specification.

This invention relates to latches and more particularly to latches for automobile doors, such for instance as that shown in patents numbered 1,312,199 or 1,386,422, granted to me on August 5, 1919 and August 2, 1921, respectively. f

Generically considered, it is the primary object and purpose of my present improvement to simplify and increase the efficiency of the means for locking the latch disclosed in the patent last referred to whereby the owner of an automobile may lock the latches of all doors except one from the interior and then lock the remaining door after he leaves the car from the exterior by means of a keyactuated lock.

ln carrying out the present invention 1 propose to provide mea-ns for locking the latch bolt retracting means against actuation which is rendered effective by means of a rectilinear-ly movable part.

More specifically, in one construction the interior operatin handle for the latch is mounted for rectilinear shifting movement. This handle -is provided with means, which, when said handle is shifted in one direction, prevents the actuation of the latch bolt by means of the exterior operating handle. At the same time, however, in certain constructions, which will hereinafter be fully described, in case the latch mechanism is thus locked while the door is opened, the bolt may be repressed or freely forced back when the door is closed, thus obviating the possibility of injuring the latch or the door structure.

1n certain contemplated embodiments of the invention, 1 also provide means for imparting the rectilinear movement to the interior latch operating handle and for securely locking said handle against movement from its effective position wherein the latch mechanism is locked against operation `by the exterior handle. lf desired, in one form orn this locking means for the interior handle,

l means actuated from the exterior of the Serial No. 509,823.

door by a suitable key may be provided, and the interior handle thereby shifted from the exterior of the door to release the latch mechanism for operation.

With the above and other objects in view, the present invention consists in the improved latch and in the form, construction and relative arrangement of the parts in the several illustrated embodiments thereof as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

Referring in detail to the drawings and more particularly to Figures 1 and 2 thereof, in which lf have illustrated a latch mechanism corresponding to that shown in my prior Patent No. 1,386,422, 10 designates the base plate upon which the several latch parts are mounted. The latch mechanism is secured in one side of the body of the door at a suitable distance below the window sill, and of course, outside of the runway in the door body into which the window is adapted to be lowered in the usual manner.

As disclosed in the patentreferred to, the latch, mechanism includes the spring projected latch bolt 11 which is mounted and guided at its rear end in an angular casting 12 fixed upon the base plate 10. This latch bolt at its outer end may be of any preferred form and construction for engagement with the striker on the door frame or the line jamb, but I preferably provide the projecting macteo means of a lever 16 which has bearing engagement against an upwardly projecting lug 17 on the latch bolt 11. This interior operating lever for the latch will presently be more particularly referred to.

To the roll-back lever 14 one end of a rod 18 is pivotally connected, said rod at its other end being freely movable through a guide opening inthe upwardly project-ing lug 19 on the casting 12.

A spring 20 surrounding said rod acts to yieldingly hold the roll-back lever against the angular flange 21 on one end of th'e base plate 10 when the latch bolt is not fully projected, and thereby prevents rattling of the lever. All of the parts above described are similar to those shown in my prior Patent No. 1,386,422 to which reference may be had for a more detailed explanation of the operation of the latch mechanism. The interior operating lever 16 for the latch extends between the base plate 10 and the latch bolt 11 and the lower portion of this lever is laterally curved as shown at 22. At its lower extremity said lever is provided with a short longitudinally extending slot 23, a notch 24 being formed at each end of said slot and communicating with one side thereof. Through the slot 23 a stud bolt 25 fixed in the base plate 10 extends. 1t will thus be understood that the lever 16 may be vertically or rectilinearly shifted, such movement of the lever being limited by the stud 25 engaging the opposite'v ends of the slot 23. l

The lever 16 extends upwardlythrough a slot provided in the window sill and may be provided with an upper adjustable section 26 which can be adjusted and fixed in any required position in accorda-nce with the location of the latch in the door body so that the operating handle 27 fixed to the upper end of the lever will be above the window sill and visible throughthe glass pane. One edge of the lever 16 is provided with alug in which a transversely disposed locking pin 28 is fixed, said pin projecting from opposite sides of the lug. One end of this pin is movable in a horizontal slot 29 formed in the base plate 10 in the operating movement of the lever. At one of its ends this slot is provided with an upward extension 30. When the lever 16 is in the position seen in Figure 1 of the drawings, the latch bolt 11 may be retracted from its projected position either by the operation of the roll-back 14 by means of the exterior handle or by the operation ofthe inside lever 16. This operating movement of the lever 16 is yieldingly resisted by the spring pressed pin 31 mounted in the lower end of the casting 12, said pin bearing against one edge of the curved lower end of the lever and operating to yieldingly hold the notched or recessed upper end of the slot 23 in engagement with Ill@ i ,esente the guide stud 25. ln the movementof the upper end ot said lever to the right from the position shown in Fig. 1, said lever pivot-s upon the stud bolt and bearing against the lug 17 retracts the latch bolt l1 so that the door may be opened. When it is desired to lock the door in closed position upon leaving the car, the lever 16 is pulled up- `wardly from the position shown in Figure 1 until the pivot stud 25 seats in the notch 24 at the lower, end of the slot 23. @ne end oit the locking pin28 will then be positioned in the upward extension of the slot 29, while the other end of said pin will be disposed in the ath of movement of the rod 18. Thus, the ever 16 is locked against pivotal movement, while the roll-back lever 14 to which rod 18 is connected is likewise locked against movement by the actuation of the exterior operating handle. llt will, therefore, be understood that each door equipped with the improved locking means is securely locked against the possibility of the same being opened from the exterior of the vehicle. This locking action may be very quickly efitected through a simple rectilinear shifting movement of the interior operating lever.

When the lever 16 is in its unlocked position, the upper end of the lever and the operating handle visible through the window pane of the door, lstands perpendicular.

- @wing to the curvature off the lower end of the lever, when said lever is raised to its locking position, the upper end thereof is disposed at an angle from the perpendicular as seen in Figures 8 and 9 of the drawings. This aliiords an indication tothe owner of the car so that he may ascertain at a glance whether or notthe door is locked, so that, if locked, he Iwill not attempt to actuate the latch by means of the exterior operatingA handle. As shownin Figure 8, if desired, the upper end portion of the lever 16 may also have embossed or otherwise delineated thereon the word Locked as indicated at 32. lWhen the lever isn in its unlocked position, this word is disposed below the upper edge of the window silLand is invisible,rbut when the lever is raised to its locked position, is disposed above the door sill'and may be readily observed.

lin Figure 3 ot the drawings T have shown another form of the invention wherein the interior lever 16 is mounted and arranged in the manner above described and is provided in one oit its edges with a notch or recess 33. @ne end of a locking lever 34, tul- Y crumed intermediate of its ends, as at 35,

is engaged in this recess. A. suitable spring 36 coacts with this lever at one sideof its pivot to normally hold the same in the position shown in full lines in Figure 3, in which position the roll-back lever 14 may be operated by means of the exterior handle to retract the latch bolt. Tn the return of the lever 16 to its normal position after the latch bolt has been retracted thereby, the end of the lockinglever 34 is received in the recess 33. `When it is desired to lock the latch, the interior lever 16 is pulled upwardly, thereby moving the locking lever 34 to the position shown in dotted lines in the drawing so that the other end of this lever is positioned in the path of movement of the upper end of the roll-back lever 14. Thus retraction of the latch bolt fromy its projected position by means of the exterior operating handle is prevented. lt will be apparent that when an attempt is made to thus retract the bolt by the exterior handle, the roll-back lever 14 will tend to rock the lever 34 on its pivot and there will be no pressure transmitted through this lever to the interior operating lever 16 such as would tend to rock the lever on its pivot 25 and retract the bolt. Therefore in this construction it is not necessary to use the locking means for the lever 16 as shown in Figures 1 and 2 of the drawings. l

ln Figure 3a of the drawings, l have shown another alternative, wherein the locking means is actuated automatically upon the movement of the inside lever to its normal position to lock the latch mechanism, while said means is manually operated independently of the inside lever to unlock the mechanism. As shown, the lever 34a is pivoted :at one end as at 35, the other or free end-of said lever being angularly oflset to extend across the inside operating lever 16" and downwardly curved as at 42. Tn this case the lever 34a also carries a pin 37 moving in the slot 38. ln the lever 16b a stud 43 is fixed, and in the movement of the lever 16b to its normal position this stud engages the upper face of the curved end 42 of the lever 34 when said lever is in the raised position and. by camming act-ion forces `said end of the lever downwardly, thereby moving the pin 37 into the lower end of the slot V38 behind the roll-back lever 14. The curved end 42 of the lever 34a in the side thereof opposed to the lever 16b is provided with a vertical recess or groove 44 and said end of the lever 34a between the groove 44 and the extremity of the'lever also has its lower portion cut away or recessed as indicated at 45. Thus when it is desired to release the latch mechanism for operation, the pin 37 is manually shifted into the upper end of the slot 38, thereby raising said lever until its curved end is positioned above the pin 43.

ln the recess 45 in the curved end 42 of the lever 34a, a dog 46 is pivoted at oneof its ends. When the lever 16b is pivotally moved from its normal position to operate the latch mechanism, with the lever 34a in the raised position, the pin 43 on said lever lifts the dog 46 so that said pin may pass through lll@ lll@

the recess 45, After passing beyond said recess the dog 46 drops by gravity to its normal position and closes the outer side of said recess so that in the return movement of the lever 16b the p-in 43 will ride over the end of said dog and upon the upper edge of the lever 34a, thereby automatically movin the lever downwardly to dispose the pin 3 in its locking position with relation to the rollback lever 14. In this construction, it will be seen that the automatic locking action is produced in a pivotal movement of the interior operating lever so that the lever is not mounted for vertical shifting movement as in the embodiments of the invention previously described.

In Figures 4, 5 and 6,-I show an adaptation of my present improvements whereby ay more direct locking action is obtained between the interior operating lever and the latch bolt. In this case the lower edge of the latch bolt 11 is provided with a notch or recess 47, one end wall of which is beveled or undercut as at 48 while the base wall 49 of said recess is inclined upwardly from said end wall 48 to the opposite end wall of the recess. The interior operatin lever 16c which is mounted for vertical shlfting movement as above explained, carries a locking stud or pin 50. When the lever 161? is in its normal operating position as seen in Figure 4, the locking pin 50 is disposed below the lower edge of the latch bolt 11, thereby permit-ting of the free retraction of said bolt by either the interior or exterior operating handles. When the lever 16b is pulled upwardly with the latch bolt in its normal position, the pin 50 moves into the recess 47 and into contact with the inclined base wall 49 of said recess. Any attempt to retract the latch bolt by the operation of the exterior handle causes the undercut wall 48 to engageone side of the pin 50, thereby tending to force the same upwardly and further increase the binding or locking engagement of the pin with the walls of said recess. Likewise, it will be evident that the lever 16c is locked against a pivotal movement when in its raised position.

In Figures 9, 10 and 11 of the drawings, I have illustrated an adaptation of my present invention as applied to an interior retracting means for the latch bolt of the type shown in Figure 5 of my Patent No. 1,386,422. In this arrangement, the interior operating handle 52 is suitably fixed to one end of the shaft 53 of a roll-back lever 54. This shaft is rotatably supported in the base plate and in a suitable bearing on the guide plate 55 which is spaced from the base plate and suitably secured thereon. Between these plates the spring held carriage 56 is slidably mounted and has a lug 57 coacting with a shoulder on the latch bolt in the manner` more fully described in my issued patent.

by the roll-back lever 54 is providedwith an extensionr yoke 58 which loosely embraces the lever 54.

The roll-back shaft 53 is also capable of an axial shifting movement in its bearings. A coil spring 59 surrounds said shaftand has "one of its ends fixed to the base plate and its other end secured to a collar 60 fixed on the shaft. This spring acts to yieldingl hold the operating handle 52 and the rolback lever 54 in normal position. This spring also resists the longitudinal shifting movement of the shaft 53 in one direction to hold the roll-back lever 54 in a recess 61 in the face of the base .plate as clearly shown in Figure 11, in which position of the roll-backy lever it will be also noted that the end of the yoke extension 58 on the carriage 56 is engaged with one edge of said lever. Thus in this normal position of the parts when the latch bolt is projected, it will be understood that the carriage 56 cannot be moved to retract the latch bolt by 4actuating the other roll-back lever 14 through the medium of the exterior operating handle. In order to release the carriage 56 for operation, theinside lever 52 yis forced towards the side of the car door and the shaft 53 shifted longitudinally in an inward direction, thus displacing the roll-back lever 54 from the recess 61. The shaft 53 may then be turned, the end of the roll-back lever moving freely in the yoke 58 and bearing against the carriage 56 to shift the saine against the action of its holding spring and thereby retract or withdraw the latch bolt. Upon the return of the interior handle and the roll-back lever 54 to its normal position, the latch mechanism is again automatically locked against operation.

In Figures 12 and 13, I have illustrated another means for locking the vertically shiftable interior latch operating lever] in its raised position. The lever isprovided upon one of its edges with a transversely projecting rib 62 and adjacent one end of this rib, a horizontally extending lug 63 is formed on the lever. Upon the surface of the window sill of the car door surrounding the slot in which the latch operatin lever moves, a plate 64 is secured, said p ate of Sti Macnee osition, upon lifting the same to lock the atch mechanism as above explained, the lug 63 is positioned above the plane of the plate 64:. The lever is then shifted transversely in the slot into contact with the inside edge thereof so that the rib 62 below the lug 63 is disposed in the notch 66 while the lug 63 is engaged upon the upper face of the platel 64 and acts as a stop preventing the downward movement of the lever.

Tn Figure 14 of the drawings I have Shown another embodiment of the invention which is more particularly applicableto an interior latch operating means of the character disclosed in my prio-r Patent No.

1,312,199. Tn this case, instead of providing' a pivotally movable interior operating lever, the latch bolt is actuated from. the interior of the car by means of a rotatable vertically disposed rod extending upwardly above the window sill of the door. As shown in Figure 14, this operating rod 67 is provided on its lower end with an operating cam 68 which engages a lug or extension 69 on the upper side of the latch bolt. The upper end of the rod above the window sill is provided with a suitable horizontally disposed handle 70 for the convenient operation of the rod 67 The rotation of this rod to retract the latch bolt is yieldingly resisted by means of the spring 71. Upon the rod 67 a sleeve 71 is loosely engaged and is provided at its lower end with a downwardly projecting finger 72 adapted to engage in a notch or recess 73 formed in the end of the rod 18 which is connected to the roll-back lever actuated by the exterior handle as above explained. A pin 74 is fixed in the sleeve 71 and is movable in a bayonet slot 75 provided in the rod 67. The sleeve 71 extends to the upper surface of the window sill, and between said upper end of the sleeve and the handle 70, a spring 76 surrounds said rod.

This spring acts to force the sleeve 71 downwardly and normally hold the finger 72 in the recess 73 of the rod 18. Tt will, therefore, be apparent that the rod 67 is thus held against operative rotation to retract the latch bolt while the rod 18A is held against movement, thus preventing retraction of the bolt by means of the exterior handle. When it is desired to operate the latch, the sleeve 71 is pulled upwardly and slightly rotated to engage the in 7 4 in the horizontal portion of the slot 5, thus disengaging the linger 72 from the rod 18'. The latch bolt can now be retracted either by theoperation of the exterior handle or by the rotation of the rod 67.

ltn the constructions to which ll have above referred, a manual operation other than that incident to the ordinary operating movement of the latch actuating lever is necessary in order to lock the mechanism. lin Figure my invention in which this locking action occurs automatically as the latch operating lever returns to its normal position in the projecting movement of the bolt. In this case, the interior lever 16d is provided with the transversely disposed locking pin 28. One end of this pin moves in a slot 29 provided in the base plate 10, said slot being slightly curved in accordance with the arc of operating movement of the lever. At its 'upperend this slotis provided with a cam portion 81. llt will be understood that in this construction the lever 16d is mounted at its lower 'end for vertical shifting movement in t-he manner shown in. Figure 1 of the drawings excepting that thel notches 24 are eliminated. rTherefore, as the lever moves towards its normal position under pressure of the latch bolt as it is projected, the pin 28 when it enters the cam portion 81 of the slotl 29 will cause said lever to move upwardly and thereby position the other end of the pin against the end of the rod 18 when said lever arrives at its normal position. The end of the cam portion 81 of the slot has a recess 82 at its lower side in which the pin 28 seats. Therefore, lateral pressure against said pin upon the attempt being made to operate the latch by the exterior handle will be ineffective to move said pin in the slot and shift the interior operating lever from its normal position.

Tn Figures 16 and 17 ll have shown another means for retaining the latch operating lever in its locking position. ln this construction the plate secured to the window sill is provided with i an upstanding flange 83 having an angular slot 84 therein, one end 85 of whichis enlarged and opens downwardly, while the other horizontally disposed end portion 86 of said slot is closed. Tn this case, the lever is constructed in two sections which are hingedly connected to each other as at 87. The upper section 16e of the lever carries a pin 88 having a terminal head 89. When the lever is in its normal perpendicular position the pin 88 is in alignment with the open end 85 of the slot 84;. The head 89 on said pin is of such diameter that it may pass through this enlarged end of the slot. Therefore, when the upper section 16e of the lever is shifted transversely to the left from the position seen in Figure 17 of the drawings, the head 89 on the in passes-through the enlarged end 85 of t e slot and in the upward movement of the lever the'shank of the pin rides upwardly through the inclined portion of the slot 84 and into the horizontal closed vend portion 86 thereof.

In Figure 18 lt have shown another means for engaging the locking pin in the angular slot of the flange or plate. In this case the operating lever 16 Ais formed 1n one piece 15, however, T have shown an embodiment of and to the lever one end of `a leaf spring 90 is fixed, said spring extending longitudinallyalong one side of the lever handle in opposed relation to a. channel or recess 91 in the handle. The pin 92 fixed at one of its ends to said spring is freely movable through an opening in the lever bar. When the handle is grasped to lift the lever to its locking position, the spring 90 is pressed into the groove of the handle and the pin 92 is thereby projected from one side of the lever bar and into the slot 84. In this construction the slot 84 and the pin 92 are of the same form as shown in Figure 18 of the drawings.

In Figure 19, a manually operated means for raising the latch operating lever to its locking position is shown. This means consists of a slide plate 94 having an inclined cam slot 95 the upper end of which is enlarged as at 96 to provide a seat for the pin 97 which is fixed in the upper end of the operating lever and engaged in said slot. The lower end of this slot 95 is open and slightly fiared so that it will readily receive the pin when the slide is moved in one direction. -Such movement of the slide is resisted by a suitable spring 98 which operates to yieldingly hold said slide in its normal position. When the slide member 94 is moved to the right from the position shown in Figure 19, the cam slot 95 coacting with the pin A97 will force the latch operating leverv upwardly to its locking position until the pin 97 seats in the enlarged end 96 of said slot whereby the slide member is held in such position and the spring 98 retained under tension. When the lever is to be moved downwardly to its operative position, such movement is started by exerting sufficient pressure against one side of the lever handle to move the pin 97 from its seat 96 into the upper end of the slot 95. The spring 98 then acts to return the slide to its normal position, the camming action of said slide upon the pin 97 forcing the lever downwardly, in which position the pin 97 is located at'y the open end of the slot 95. The lever may now be actuated to retract the latch bolt.

In Figures 20, 21, I have disclosed a keyactuated means operable from the exterior of the car door for shifting the interior latch actuating lever. `This means consists of a plate 99 pivotally mounted as at 100 upon the inner wall of the slot or channel in the door body in which the interior operating lever is movable. The `plate 99 is provided in one side with an" arcuate channel or groove 101 open at one of its ends and in which the pin or stud 102 on the latch operating lever is engaged. This plate also has an arm 103 extending downwardly from its p1voted end. A key-actuated cylinder lock generally indicated at 104 is mounted in the door body above the exterior operating handle for the latch, the lock cylinder having an arm 105 on its inner end which is operatively connected by means of a bar 106 to the arm 103. Thus, as seen in Figure 20, the interior latch actuating lever mounted and arranged as shown in the several embodiments of the invention above referred to may be vertically shifted to lock said lever as well as the exterior operating handle for the latch mechanism by means of a suitable key inserted into the lock 104 after the door has been closed. Upon turning the key in the proper direction, through the connection 106, the plate 99 is shifted to the dotted line position. The walls of the arcuate cam groove 101 coacting with the pin 102 will thus act to force the interior operating lever upwardly to its efiectivle locking position. A reverse movement of said plate by means of the locking key will, of course, move the lever `downwardly s0 that the exterior operating handle may be actuated to retract the latch bolt.

From the foregoing description considered in connection with the accompanying drawings, the construction, manner of operation and several advantages' of the various embodiments of the invention herein disclosed will be clearly understood. In so far as I am aware, I am the first in the art to provide means controlled by a manipulation of the latch operating handle for rendering such means effective to prevent the operation of the latch mechanism to retract lthe bolt, or on the other hand, to render such locking means ineffective in the event. that independent means is provided for actuating the locking means to preventv retraction of the bolt. It will be apparent that my present improvements particularly as illustrated in Figure 1 of the drawings, provides a much simpler and more easily operable, locking means for the latch mechanism than that disclosed in my issued Patent No. 1,386,422. The present improved construction has also been found to be very effective and reliable in actual operation.

While I have herein shown and described several possible alternative forms of the generic invention involved in this application, it will nevertheless be understood that the device is also susceptible of still further modifications and I therefore reserve the prlvllege of resortin to'all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.
