16 Claims.

This invention relates to locks.

The type of lock to which this invention is directed to disclosed in my co-pending application Serial No. 483,174,1iled September 20th, 1930, and it is the object of this invention to generally improve and simplify the same.

Another object of this invention is to provide in a lock of the character described wherein a pair of vertical bolts are moved outwardly away from each other into engagement with a keeper, simultaneously with the projection of a horizontal bolt, invertible actuating mechanism for converting the lock for use with vertical bolts adapted to be moved inwardly toward each other upon projection of said horizontal bolt. i

A further object of this invention is to provide a neat, compact and strong lock of the character described which shall comprise few andisimple parts, which shall be of economical construction, smooth and positive in operation, which shall be easy to assemble and disassemble and which shall yet be practical and efficient to a high degree.

Other objects of this'invention will in part bev obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a rear elevational View of a lock embodying the invention with the rear `cover plate removed;

Fig. 2 is a cross-sectional view takenon line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional View takenon line BB of Fig. 1;

Fig, 4 is a frontelevational view of a lock em bodying the invention provided with vertical bolts adapted to be moved inwardly toward each other upon projection of the horizontal bolt, and showing parts of the lock structure of Fig.' A1 in reversed or inverted position for coaction with said vertical bolts.

Fig. 5 is a cross-sectional View taken on line 5 5 of Fig. 1; and

Fig. 6 is an end elevational view'o'f the lock casing.

Referring now in detail tothe drawings, 10 designates a portion of a door on which is mounted, adjacent the vertical edge 11 thereof, a lock 12 here shown as carrying a plurality of bolts i930, serai No. 487,969

(o1. vii- 74) adapted to cooperate in the manner hereinafter described with a strike or keeper 14 attached to the door jamb 15. The lock 12 comprises a casing 12a having a front Wall 18, top and

bottom walls

19 and 20, an end wall 21 remote from the 60 i edge 11 of the door, and a'second end wall 22 26 adjacent said rear edge 25 thereof, for seating 7.0`

a cover plate 27. Said cover plate may be secured to said casing in any suitable manner, as for instance rby meansv of screws -extending through threaded openings 30 in bosses 31 integrally formed with the top andbottom walls 19 75 and 20 of said casing 12a.. `The casing 12a furthermore may be formed with symmetrical aligned wall portions 32 extending outwardly from said top and

bottom Walls

19 and 20 and disposed parallel to the end wall 22. Extending outwardly from said top and

bottom walls

19 and 20 are walls 33 parallel to the front wall 18 and joining the

walls

32 and 22. It will be noted that the

walls

32, 33 and 22 form with the cover plate 27 a pair of tubular openings 35 at the top and bottom of the casing adjacent the front wall 22 and communicating with the interior of the casing.

For the purpose hereinafter appearing, the front wall 18 is formed with a pair of integral parallel ledges or

guides

36, 37. The boss 31 extending from 'the rbottom wall 20 may likewise be provided with a flat surface V39 parallel to said

steps

36, 37. Slidably mounted within the casing 12a, and guided by and between the parallel step 37 and said surface 39, is a member 40 having a plate portion 41 parallel to said front wall 18. Said member 40 is provided with an extension 41a resting on and guided between the

steps

36, 37. Extending from said plate 41 at right angles thereto is an integral plate portion or wall 42 disposed parallel to the end wall 22 of the casing.

It will be noted that said member 40 may be reciprocated within the casing 12d.- The front wall 18 of the casing may be provided adjacent the top and

bottom walls

19 and 20 thereof with parallel ledges 40a and 40h, supporting and serving as guides for the end portions 42a and -42b of said wall 42. i i

Means is provided for reciprocating saidV member 40 within the casing. To this end, the front wall 18 of the casing is formed with an integral boss 50 having a bore rotatably receiving a nger knob 51 projecting into the casing. Fixed to the inner end of the knob is an arm 52 having a pin 52a at the outer end thereof pivoted to one end of a link member 53, said link being pivotally attached at the other end thereof to pin 54 iixed to said plate 41.

It will now be seen that upon rotating the knob 51, the arm 52 is rotated therewith for moving the link 53 and causing sliding movement of the member 40. Any suitable key control mechanism 56 may be mounted on a cover plate 27 and provided with an arm 57 substantially contacting the nism 56, the arm 57 is rotated and the lug 58l actuates the link 53 for translating said member 40.

A coil spring 59 may be mounted on a rearward extension of said pin 54, and provided with end extensions 60 engaging portion 53a. of the link 53 and the plate portion 42 for normally urging said member 40 toward the end of its stroke in either direction. The wall 42 is provided with a pair of spaced symmetrical openings 61 and the front wall 22 of the casing is provided with a pair of openings 62 aligned with said openings 61, for the purpose hereinafter appearing.

Mounted on said wall 42 are a pair of horizontal similar bolts'63 and 64 having reduced

portions

63a and 64a extending thru saidopenings 61, the end portions of said bolts being slidably disposed within the openings 62 in end wall 22. Extending rearwardly from and iixed to plate portion 41 of said member 40 are

pins

65 and 66, said pins extending thru said

portionsy

63a and 64a of said

bolts

63, 64, respectively, for xin said bolts to said member 46.

It will thus be seen that -thebolts 63, 64are xed to member 40 by means of

pins

65, 66 re' spectively, and that said bolts may be projected from the casing or retracted into the casing upon actuation of the finger knob 51 or the key actuating mechanism 56. As illustrated in Fig. 1 of the drawings, the lock is provided with a pair of vertical bolts 70, 71 adapted to be moved outwardly away from each other simultaneously with the projection of the

horizontal bolts

63, 64. Said bolts 70 andy 7l are symmetrically disposed with respect to one another and are provided with

portions

72 and 73 respectively slidably extending within the tubular'openings 35 of the casing 120;. Extending inwardly from said

portions

72, 73 are

iiat plate portions

74, 75 having pins 74m and 75a fixed thereto adjacent the inner ends thereof and projecting rearwardly toward said cover plate 27. Mounted within the casing adjacent the'cover plate 27 and disposed between said cover plate and the wall 42 of member 40 are a pair of symmetrically disposed plate members and 8l to be described in detail hereinafter.` Said

members

80 and 81 are provided adjacent one end thereof, with substantially

ovalshaped slots

82 and 83 respectively, pivotally and slidably receiving said pins 74a and 75a. Said

members

80, 81 are furthermore pivoted adjacent the oppositeend to the cover plate 27 by means of

pins

84, 85 iixed to the inner side of said cover plate. Said

members

80 and 81 are also provided with elongated inclined slots 87 and88 respectively,

slidably receiving the upper ends of the

pins

65, 66. As shown in Fig. 1, the

slots

87, 88 are inclined inwardly toward each other and toward end wall 22 and are, further symmetrically disposed with respect to the longitudinal mid-section of the casing. It will thus be seen that upon actuation of the knob 51 for moving the member 40 to the right, as seen in Fig. 1, the

bolts

63, 65 will be projected from-the casing and the

pins

65, 66 will move within the

slots

87, 88 for causing pivotal movement of the

members

80, 81 about

pins

84, 85, away from one another. Such movement of said

members

80, 81 will cause outward sliding 'movement of the bolts 70, 71 away from each other, due to the pin and

slot connections

74a, 82 and 75a, 83, into engagement with keeper 14. Said

members

80, 81 thus have cammed connections with the bolts. Obviously, actuation of the knob 51 in the opposite direction will cause member 40 to slide to the left for retracting the

bolts

63, 65 and causing pivotal movement of the

members

80, 81 about the

pins

84, 85 inwardly toward each other. This action will move the bolts 70, 7l inwardly toward one another for disengaging the same from the keeper 14. Said bolts 70, 7l are provided with

portions

90 and 91 respectively, parallel to each other and adapted to overlap the door jamb. Said bolts are furthermore provided with outwardly extending aligned

portions

92 and 93 adapted to engage within suitable openings in said keeper 14. Said keeper obviously is provided with suitable openings for receiving the forward ends of the

horizontal bolts

63, 64 whereby both horizontal and vertical bolts may be simultaneously moved into engagement with or out of `engagement from said keeper.

In Fig. 4, the

bolts

100 and 101 are U-shaped and are

providedzwith portions

102 and 103 extending inwardly toward each other and adapted to'engage Within

openings

104 and 105 respectively, of a keeper 106. The pivoted

members

80 and 81 however, are inverted from the position shown inFig. l so that the

inclined slots

87 and 88 will diverge away from the longitudinal midsection of the casing and toward the end wall 22 instead of toward said mid-section and toward said end wall, as rshown in Fig. 1. Said

members

80 and 81 are pivoted to the cover plate 27 by means of said pins 84, 85 and are also provided with

slots

82 and 83 slidably receiving therethrough, pins 107 and 108 extending rearwardly from inner portions of the

bolts

100 and 101.

It will now be understood that upon projection of the

bolts

63, 64 the

members

80 and 81 will be pivotally moved toward each other due to the action of the

pins

65 and 66 within said

slots

87, 88. This movement of the

members

80 and 81 will cause the

U-shaped bolts

100 and 101 to move inwardly toward each other into engagement with the strike 106, the

horizontal bolts

63 and 64 simultaneously moving into engagement within openings 109 and 110 in said keeper. Actuation of the finger knob in the opposite direction will cause retraction of the

horizontal bolts

63, 64 and movement of the pivoted

members

80, 81 away from each other spreading the

bolts

100 and 101 and disengaging the

portions

102 and 103 thereof from the strike 106.' Y

It will thus be seen that for adapting the lock shown in Fig. 1 for use with bolts to be moved inwardly toward each other upon projection of the horizontal bolts, the pivoted

members

80 and 81 need merely be inverted in the manner illustrated and described, and the

U-shaped bolts

100 and 101 substituted for the bolts 70 and 71.

It will thus be seen that there is'provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodimentset forth, it is to be understood that all matter herein set forth or shown in the accompanying drawingsis to be interpreted as illustrative and not in a limiting sense.
