4 Claims. (01. 292-166) My invention 1 relates to new and useful improvements in locks, and more particularly to a lock of the type wherein rotary handles are eliminated, the primary object of the invention being to provide a lock of the character mentioned, which upon the pushing of a, button will enable the door or the like to be opened.

A further object of the invention resides in the provision of a lock of the character mentioned which is capable of being applied to a door and operable, by the pushing of a button, from either side.

A still further object resides in the provision of a lock which is not only operable by the pushing of a button from either side, but which is capable also of being secured in position with key.

Still another object resides in providing a lock of the character mentioned which is simple and durable in construction, inexpensive to manufacture and one that will be very efiicient and useful in operation.

With these and numerous other objects in view, my invention consists in novel features of construction, combination and arrangement of parts as will be hereinafter referred to, and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application Figure 1 is an edge elevation of an automobile door having a lock designed in accordance with my invention applied thereto.

Figure 2 is a side elevation looking in the direction of the arrow A indicated in Figure 1.

Figure 3 is a view similar to Figure 2, but looking in the direction of the arrow B.

Figure 4 is a view in side elevation similar to Figure 1, but with the front face plate removed in order to disclose the interior construction.

Figure 5 is a section view taken substantially on line 55 of Figure 7.

Figure 6 is a horizontal section on line 6-6 of Figure 4.

Figure 7 is a horizontal section taken on line 1--1 of Figure 4.

Figure 8 is a vertical sectional view taken on Figure 12 is a horizontal section taken on line l2-l 2 of Figure 9.

Figure 13 is a horizontal section taken substantially on line l3! 3 of Figure 16.

Figure 14 is a view similar to view 13, but showing the key inserted in the cylinder and given a turn of degrees in order to dispose the pin on the extreme end of the cylinder in such a posi-- tion that the inward movement of the latch bolt is broken.

Figure 15 is a fragmentary sectional view showing how the inward movement of the latch bolt is now broken by virtue of the fact that a threaded bolt has been moved inwardly in the direction of the arrow.

Figure 16 is a vertical section taken on line 16-45 of Figure 13.

Figure 17 is a section View taken substantially on line ll-il of Figure 13. The pin on the extreme end of the-locking cylinder is now disposed in a longitudinally extended recess in the latch bolt and thus permits inward movement of the latch bolt.

Figure 18 is a view similar to Figure 17 but showing the pin on the end of the locking cylinder disposed toward the rear face of the latch bolt thus preventing an inward movement of the latch bolt. When observing Figures 17 and 18, it will be noted that the two positions shown by the locking cylinder are the only ones possible. In

' other words, the locking cylinder has been given a turn in order to shift the locking pin from its position in the recess of the latch bolt, to a position where it abuts the rear face of the latch bolt. It will also be noted that a small pin projecting from the locking cylinder travels in a groove in a portion or" the cylinder casing and thus the movement of the cylinder by means of the key is definitely limited.

Figure 18A is a fragmentary perspective view of the key in operating position of the lock removed.

Figure 19 is a. side elevation of the housing which accommodates the sliding movement of the latch bolt.

Figure 20 is a horizontal section taken on line 2t!--2i! of Figure 19.

Figure 21 is a vertical section taken on line 2P4! of Figure 19.

Figure 22 is a side elevation of the latch bolt the door associated with a spring pressed button in order to assist the opening of the door after the latch bolt has been released.

Figure 25 is a side elevation of the spring pressed button for assisting in opening the door after it has been freed from the confining latch bolt.

Figure 26 is a section view thereof.

Figures 27, 28, 29, 30, 31 and 32 disclose a modification of my look. This lock is clearly simplified. and likely to be used on refrigerators and similar appliances.

Figure 27 more particularly shows a transverse horizontal section showing a modification of my improved lock,

Figure 28 is a front elevation on enlarged scale.

Figure 29 is an edge View thereof.

Figure 30 is a similar view to Figure 29, but showing the face plate removed in order to disclose the interior construction.

Figure 31 is a central vertical longitudinal section taken on line 3 i--8i of Figure 33.

Figure 32 a horizontal section taken on an enlarged scale on line 1-l232 of Figure 29 and showing the association of the lock bolt with its coacting keeper.

My invention is particularly adapted to use in connection with doors of automobiles wherein difiiculties have been encountered with the operating handles. Handles on au oinobile doors frequently become loose or distorted, causing rattles, and often are difficult to operate. Again, handles on automobile doors have become engaged with garments of the riders causing damage. My invention contempiates the elimination of door handles. While, as stated, the lock covered in this application is particularly adapted for use in connection wit automobile doors, it is also equally adapted for use in connection with refrigerators or other containers having doors thereon with looks or latches ordinarily requiring operating handles and, as shown in Figures 27 to 32, inclusive, I have shown application to use of a lock on a door of a container, with the basic principles of the improved look similar to that in the lock applicable to automobile doors.

In referring to the drawings, forming a part of this application, the numeral i designates the door of an automobile, hingedly mounted on the body 15 thereof. My improved lock is ap plied to the door so that the latch bolt 3 thereof projects from the edge of the door and is adapted to be retained in the keeper 3 of the body, as best illustrated in Figure 2a of the drawings. The important features of my lock obviously involve the actuation of this latch bolt 3 without the use of rotating door handles.

This latch bolt is reciprocally mounted in a shell or housing i, which housing or shell is mounted removably, as shown at 5 to one wall of the casing The outer end of this shell or housing through which the latch bolt 3 operates registers with an opening I in a cover plate 8 fitted over one side of the housing a and covers the edge of the door I, as clearly shown in Figure 1 of the drawings, whereby said latch bolt may project through said plate 8 and engage the keeper 3 as the door is moved to its closed position. This plate a is secured in position to the casing i: by means of the screws 9 and said plate is further secured to the edge of the door i by means of the screws it.

The latch bolt 3 has mounted therein for projection outwardly from the top and bottom face thereof, adjacent the inner end thereof, the pins H, which project through slots 52 formed in the top and bottom walls of the shell or housing 5. The inner end of the bolt 3 a socket [3 formed therein in which is dispose-.. a coil spring M, the innermost end of the coil spring being mounted against the one side wal of the casing Q. A pin it projecting from the last mentioned wall of the casing is extended through the coil spring to act as a g ide or anchor therefor. Obviously the coil spring has a tendency to normally force the latch bolt to its extended position, shown in Fi ure 8 of the drawings, the pins ii operating in the slots 12 of the housing 5' acting as a means of l nitation for the outward movement sai" bolt. In Figure 10, I have shown the positioi bolt 3 and its adjunctive parts when said bolt is moved to a retracted position against the tension of the spring Hi.

As stated heretofore, my improved lock is particularly applicable to use in an automobile door Which naturally is to be opened from within as well as from without the body. I have provided specific means for accomplishing this desired end with push buttons or the like. To this end, 1 provide on the inner faces of the front and rear walls of the casing 6 the pairs of bearings It and ll, the former being mounted on the inner face of the front wall of said casing and the latter being mounted on the inner face of the rear wall of said casing. Rotatabiy mounted in the bearings I6 is a bar 18 which has a pair of spaced laterally extending arms if), somewhat curved and adapted to normally rest upon the projecting mm H carried on the latch bolt 3. The upper end of the bar is is bent angularly rearward to form a lever 2'6, and the free end thereof is curved laterally, as shown at 21. The rear wall of the casing B has an opening formed therein around which is fitted a cylindrical housing "22 which receives therein the head 23 of a plunger 24. This head 23 is in the form of a push button and normally projects beyond the inner face of the door i, as shown in Figures 1, 4 and 5. The innermost end of the plunger '25 is provided with a cap 25 which is adapted to contact with the laterally extending lever 26 of the rotatable bar t8. Under normal conditions, the bolt 3 in its extended position under action of the spring i3 will cause, through contact of the pins H with the arms ill, the bar it to be rotated to a position, as shown in Figures '4 and 5, so that the laterally bent end 2"! of the lever 29 will force the plunger 2 outwardly and the head 23 to its extended position. Upon the pressure inwardly of the h ad or button 23, as shown in Figure 9, the cap 25 on the plunger 24 will cause a rotation of the bar it correspondingly forcing the arms it to act on the pins H so as to retract the bolt 3 to a position, as shown in Figures 9 and 10. Thus, it will be seen that the latch bolt ma be readily retracted from Within the automobile by pressure on "the button or head 23.

As stated, I have provided for the ready opening of the door from the outside. From this end, 'I have provided a second oscillating bar 25 which is mounted for rotation in the bearings IT. This bar 26 which extends vertically in parallelism with the bar it is also provided with laterally extending somewhat curved arms 2i which normally rest also upon the projecting pins ll of the latch bolt 3. These arms '27 of the bar 23 are shown disposed between arms IQ of the bar H3 and the housing 4 of the latch bolt and in spaced relation to the arms l9. The lower end of the oscillating bar 23 is bent angularly to form a lever 23, and the extreme end of said bent portion is laterally bent as shown at 29, and normally contacts with the cap or inner head 30 of a plunger 3| having an outer button-like head 32. This plunger with its cap and head is similar to the push button type plunger previously described and operates in the same man ner, except that the head 32 projects through the front wall of the casing 6 beyond the front wall of the door A front plate 33 is applied to the front face of the door and secured to the casing 3, said latter plate being also provided with an opening 34 registering with the plunger opening in the front wall of the casing (i so as to receive therethrough the head of the plunger or push button 32. From this construction, it will be seen that in the normally extended position of the latch bolt 3, the pins thereof contacting with the arms 21 of the bar 25 will cause rotation of the latter to a position, as shown in Figures 4 and 5, which forces the plunger 3| outwardly and the button or head 32 to its extended position. When the button 23 is moved inwardly, as shown in Figure 9 of the drawings, such action, even though retracting the bolt 3, will not aiTect the bar 26 or the button 32. However, when the button 32 is forced inwardly from the outside of the door, the corresponding rotation of the bar 25 will so act on the arms 21 to cause retraction of the latch bolt 3, but such retraction of the bolt from the outside of the door will not affect the bar l8 and the push button head 23. In other words, the latch bolt 3 may be actuated independently from the inside or from the outside of the door and the operation from the one side will not afiect the elements to be operated from the other side.

Obviously, when the latch bolt 3 is retracted by the pushing of buttons 23 or 32, the door is in position to be opened. Since this type of lock contemplates elimination of handles, I have provided means for automatically opening the door upon the retraction of the bolt. To this end, the body 2 of the automobile or other structure, at the edge of the doorway adjacent the hinged end of the door I is provided with a cylindrical socket in which is mounted a cylindrical member 35. The inner end of this cylindrical member is threaded and has engaged therewith a threaded block 33 forming a base for the member. This member is hollow and has a head 31 thereon which is provided with an opening 39 and projecting through the opening 33 is a hollow stud 39, the outer end of which is closed and the inner end of which is formed with an annular flange 40 adapted to engage the inner face of the head 31. Interposed between the threaded block 35 and the closed end of the stud 39 is a coil spring 4| so that said stud 39 is normally held in a projected position, as shown in Figure 26. With this spring held stud mounted in the edge of the doorway at the hinged end of the door, as shown in Figure 24, it is apparent that upon the retraction of the latch bolt 3, said spring stud 39 will cause the door I to be slightly sprung open. It then may be opened to its full position for entry and exit of passengers to and from the automobile.

I have provided means for looking or securing the latch bolt 3 in its effective latched or looking position, such means operating from either the inner or outer sides of the door I. Considering first the means for locking the latch bolt, from the inner side of the door, the rear wall of the casing 6 is provided with a threaded opening through which passes a threaded bolt 4|, the outer end of which is provided with a knurled head 42. The adjacent wall of the housing 4 in which the latch bolt 3 operates is provided with an opening 43 which is in alignment with the opening 40, so that upon turning the head 42 clockwise,the bolt 4| may be projected through the opening 43, as shown in Figure 15 of the drawings. In such position, it will be seen that the end of the bolt 4| is in the rear of the inner most end of the bolt 3 and said bolt may not under such conditions be retracted by pressur on either of the push button heads 23 or 32. Thus, it will be seen that the latch bolt may be locked or secured in its effective latching or looking position from within the automobile or other structure. By withdrawin the threaded bolt 4| to a position, as shown in Figure 13, it is apparent that the bolt 3 may be retracted.

Locking the latch bolt from the outside of the door, as usual, is accomplished through the medium of a key. In carrying out this operation, the front wall of the housing 4 opposite the wall having the opening 43 therein is provided with an opening 44 which is adapted to receive therein a cylinder 45 carried on the lock 46, which is r0- tatably mounted in the front plate 33 and the front wall of the casing 6, as clearly shown in Figures 13, 14 and 16 of the drawings. The lock 46 is provided with a key slot 4'! adapted to receive a key 48, which latter engages the end of the cylinder 45, although this engagement is not shown, whereby said cylinder may be rotated by the key. Carried on the inner end of the cylinder 45 and extended longitudinally thereof from an eccentric position thereon is a stud 49, which in the unlocked position of the latch bolt 3 is located within a slot 59 formed in the front face of said latch bolt, as clearly shown in Figure 13 of the drawings. When the stud 49 is disposed within the slot or groove 50 of the latch bolt 3, as shown in Figures 13 and 16, it is apparent that said latch bolt may be readily retracted. Upon the turning of the key 48 to a position, as shown in Figure 14, the cylinder 45 will be rotated so that the stud 49 thereof is rearward of the inner end of the latch bolt 3 and in a longitudinal plane beyond the longitudinal plane of the slot or groove 50. Thus, said stud 49 will act as :a stop for the inward or retraction movement of the latch bolt 3 thereby locking the latter in its extended or efiective latched position. The rotary movement of the key 48 and the cylinder 4-5 is controlled by providing the cylinder with a laterally or radially extending stud 5| which operates within a groove or cut-out portion 52 formed in the inner end of the cylinder lock member or casing 46. This is best illustrated in Figure 18A, wherein it will be observed that the stud 5| will abut shoulders formed in the member 45 at the ends of the cut-out portion 52. When the stud 5| is in abutment with one shoulder, the stud 49 may be disposed in the slot or groove 59 of the latch bolt to allow free retraction of the latter, whereas when the stud 5| is in abutment with the opposite shoulder, said stud 49 will be rearward of the latch bolt 3 to lock the latter in its extended position. Thus, it will be seen that the latch bolt may be locked or released from the outside of the door through the medium of the key.

I have heretofore described my improved lock" applied to the door of an automobile or other structure which is adapted to contain humans, so that actuation of the door from either one side or the other is necessarily provided. In Figures 27 to 32, inclusive, I have shown a slight modification of my invention wherein the lock is applied to the door of a container or device which merely requires actuation from the outside, as, for example, a refrigerator or the like. To this end, I have shown a door 53 applied in the doorway of a structure the door being hinged, as shown at 55, and provided with a latch bolt 56 adapted to be held in a keeper 57. When the latch bolt is retracted, the door is adapted to be sprung open automatically by means of a door opening device 58 operating at the hinged end of the door, said device being similar to that previously described and shown in Figures 25 and 26.

The bolt 56 is slidably mounted in a housing 59, the opposed side walls of said housing being slotted, as shown at 6G, to receive therethrough the pins 6! carried by the bolt. Under normal conditions, the latch bolt 56 is disposed to its extended position under action of a coil spring 62 mounted in the housing 5% and coacting with the bolt 55 in the same manner as the spring I13 described previously. This particular form of lock employs a front plate 63 which is provided with an opening to receive therethrough a push button head 64 operating through a casing 85 carried on the inner face of said plate 63. The head SL is carried on a plunger 55 having a cap at its inner end, which cap is adapted to cooperate with the end of the angular bent lever 6? of a rod 68. The rod 68 .is similar to the rod 26 heretofore described, the same being oscillatingly mounted in bearings 69, which are carried on the rear wall of the casing 19 of this lock. This rod '58 has a pair of laterally extending arms H formed thereon, which are slightly curved, and under normal conditions rest upon the pins 63. Obviously, upon pressure on the push button head 64, the rod 68 will be caused to partially rotate in its bearings 39 which in turn causes the arms 7'! to force the pins in the same direction against the action of the coil spring 62, thereby retracting the latch bolt 55. Thus, upon one movement of the push button its, the latch may be retracted and the door 53 automatically disposed to its open position under action of the spring in the element It is apparent of what great value a lock of this type may be in connection with a refrigerator or other container.

From the foregoing description of the construction of my improved lock, the assembly and operation thereof will be readily understood, and it will be seen that I have provided a simple, inexpensive and efiicient means for carrying out the various objects of my invention.

While I have particularly described the elements best adapted to perform the functions set forth, it is apparent that various changes in form, proportion and in the minor details of construction may be resorted to, without dissenting from the spirit or sacrificing any of the principles of the invention.

What I claim is:

1. In a lock of the class described, a casing, a latch bolt reciprocally mounted therein, a housing for said latch bolt having slots in opposite side walls thereof, pins extending laterally from opposite sides of said bolt and projected through said slots of the housing, whereby the movement of the bolt outwardly is limited, spring means normally directing said bolt to its extended position with respect to the casing, a rod oscillatingly mounted within said casing substantially parallel to the pins and having lateral arms thereon contacting the pins on said bolt, and means manually operable from without said casing to oscillate said rod and correspondingly retract said bolt.
