Specification of Letters Patent.
a new and Improved Look, of which the following is a full, clear, and exact description.
This invention comprehends new and useful improvements in locks, and relates more particularly to those of a type commonly designated as double-door locks.
The primary object of the invention is to provide a lock of this nature, which is an improvement on the invention forming the subject of Patent No. 966,208, granted to me August 2, 1910.
In addition to the objects stated in my prior patent, the invention aims to provide a lock which will be less complicated, and easier to make from cast or malleable iron; and to provide a lock the actuating elements of which shall have ample leve age to enable a child to operate the same.
The invention also aims to provide means whereby the bolts carried by the master door may be locked in their extended or retracted positions by the same mechanism, said bolts also serving to lock the bolts carried by the controlled door in their :rtended positions.
The invention. aims toward a general improvement over my original lock, particularly in the manner in which the bolts are locked in position and in many minor details of construction.
Another object of the invention is to pr vide a lock which shall be cheap to manufacture, durable, easily applied and operated, and which may be applied to doors which swing both ways.
lVith these and other objects in view, as 3 will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as shall be hereinafter fully described and claimed F or a complete understanding of my invention reference is to be had to the follow ing description and accompanying drawings, in which- Figure 1 is a fragmentary vertical sectional view of the meeting edges of the doors,

bolts retracted; Fig. 2 is a similar view, showing the bolts extended and locked in said extended position; Fig. 3 shows the bolts carried by the master door locked in their retracted positions, and the bolts carried by the controlled door in their extended l positions, but not lock d; Fig. 4 is an elevation of the mechanism carried by the master door, showing the bolts in their retracted positions and the locking mechanism therefor disengaged from the slide plate, where by the bolts are free to move outwardly; l 5 is a detailed view of the boltlocking mechanisms carried by the master and the controlled doors; Fig. 6 is a sectional view taken on the plane of line 6-6 of Fig. 5; Figs. 7, 8, 9, 10 and 11 are detailed views of parts to be hereinafter fully described.
In the following description and accompanying drawings, similar parts will be re ferred to and designated by like reference characters.
Referring to the drawings by numerals, designates bolts arranged to enter a lock casing 6 in the path of the latch heads 7 when in looking position, and thereby prevent the withdrawal of the upper and lower bolts 8 and 9. The locking mechanism contained in the casing 10 1 term the master lock, and the door 11 in which said casing 10 is mounted is styled by me the master door. The bolts 5 are provided with longitudinally-extending shanks 12, which slide through the guides 13 formed integrally with the casing 10 and cover plate 13, a section of which is shown in Fig. 11. These guides 13 are formed in sections, said sec tions being carried by the casing 10 and the cover plates 13 respectively. Spiral springs 14: encircle the shanks 12, and by bearing against the inner ends of the bolts 5 and the guides 13, tend to hold said bolts normally in their extended positions. he leads of the bolts 5 are rectangular and eX- tend through openings provided in the plate 153. The bolts are limited in their forward throw and retracted therefrom by lugs 16, which bear against the downturned ends 17, which are formed upon the yoke ends of a slide plate 19. The slide plate 19 is guided, by a recess 20 formed in the rear extension thereof to surround the barrel of a rollback 21 and a projection 21 carried by the casing plate 13. The roll-back is formed with pivotal extensions 22 which are extended through the sides of the casing, and which are to be rotated therein. To rotate the roll-back there is provided a squared hole 23, through which is extended the squared shank 24, upon the ends of which are secured door knobs. Extending from the side of the roll-back 21 is a segmental extension 25, having slightly curved ends which engage the overturned ends 26 of the slide plate 19. It will be noted that these overturned ends have outwardly-inclined inner walls, whereby the extension 25 will work freely thereagainst, when it is rotated, in order to draw the slide plate 19 inwardly. -When the shank 24 is rotated, the extension 25 of the roll-back will contact with one of the overturned ends 26 of the slide plat 19, whereby the latter will be drawn inwardly, carrying with it the bolts 5 and compressing the springs 14.
The foregoing described parts of my improved lock are essentially similar to the corresponding parts disclosed in my former patent, above referred to, the only changes being in the form of the guides 13, the slightly curving ends of the extension 25 and the provision of a projection 21 upon one side of the casing 10.
The plate 19 may be freely moved to withdraw the bolts 5, in the manner stated, until prevented by the interposition of the sliding stops 27 and 28. Each of said stops is provided with a laterally extending projection 29, having an inclined front edge. The steps are reduced in thickness at their inner ends by cutting away portions from the under side thereof, and each of said re duced portions is provided with a pivot lug 30, which lugs fit within openings formed in the ends of the pivoted link 31. This link is centrally apertured for the reception of a pivot lug 32 formed upon one side of the casing 10. A, locking lever is pivotally connected at one end to the sliding stop 28 and is provided upon one edge with the notches 34. A fiat metal spring 35 is se cured at one of its ends to the pivoted lever 33 and bears at its other end against the lug 36 carried by the sliding stop 28, said stop being recessed upon one edge as shown at 37. The sliding stop 27 is curved rearwarclly at its inner end and has formed thereon the rib 38 which is adapted for engagement within either of the notches 34. The spring 35 tends to normally hold one of the notches in the pivoted lever 33 against the rib 38 whereby the sliding stops 27 and 28 are held against movement.
As shown in Fig. 1, the bolts 5 are retracted, and the sliding stops are extended so as to cause their projections 29 to engage the ends of the slidin )late 19. thus we- D venting a forward movement of said plate, whereby the bolts 5 are held against outward movement. In order to withdraw the sliding stops from engagement with the ends 17 of the sliding plate 19, a suitable key is inserted within the key hole 39 and turned so as to engage the inner wall of the recess 37 and at the same time force the pivoted lever 33 from engagement with the rib 38. A further movement of the key will cause the sliding stop 28, and also the sliding stop 27, because of the pivoted link 31, to move inwardly. The walls of the innermost notch 34 of the pivoted lever 33 will engage the rib 38 and lock the sliding stops, as clearly shown in Fig. 4. If it is desired to lock the sliding bolts 5 in their retracted positions, the sliding stops are moved outwardly into engagement with the lugs 16, as clearly shown in Fig. 1.
The bolts 5 are rounded on their forward ends to ride easily over the forward edge of the casing 6, which is provided with the bolt holes 41. The casing 6 contains the mechanism for operating the bolts 8 and 9. These bolts project into keepers 42 and are mean ed in the box casings 43, which are provided with perforations through which the shanks 44 protrude. These shanks are encircled by spiral springs 45 which normally hold the bolts 8 and 9 in their full out vard position. The bolts are retracted from the outward extension by draw rods 46, connected at their outer ends to the bolts, as shown in the drawings and having their inner ends threaded. The threaded inner end of each of the draw rods 46 projects through the end of a yoke 47 and is held therein by means of a nut 48. This construction permits the throw of the bolts 8, 9, to be adjusted. The inner end of each yoke is connected by a rod 49, said rod being held within a slot 50 formed in each of the latch heads 7. This construction permits the yokes 47 to be easily disconnected from the latch heads. The quadrants 51 are pivoted at 52 and are each provided with gear pivots 53 which mesh with the teeth 54 formed upon a sliding plunger This plunger is provided upon each end wi h a longitudinal projection and is centrally apertured as shown in the drawing. Guide lugs 56 are formed upon one side of the casin 6 and limit the movement of the plunger in one direction. The rear projection formed upon the sliding plunger 55 works through an opening in the rear of the casing. A roll-back 57 having the curved projection 59 is mounted upon and rotated by a square shank 60. The roll-back may be rotated so as to cause either of the shoulders 61 to engage the plunger 55 and carry it rearwardly, in which position one of the teeth 62 will engage one of the recesses 63 formed in the projection 59, and cause the plunger 55 to be drawn farther rearwardly. Vhen shank 0 is released, springs +15 return it to place.
In order to lock the sliding plunger in its backward position, I provide the sliding stop G l having the laterally extending projection and the recess 66. A pivoted locking lever 67, having one of its edges notched, as at 68, is pivotally connected to the sliding stop (it and carries a spring 69, which tends to normally hold the walls of one of the notches 68 in engagement with a lug 0, formed u pon one side of the casing 6. This lug serves as a guide for the sliding stop 64 and also, by engaging one of the notches 68, locks the stop against movement.
hen desired to have the push door open, it is necessary to rotate square shank 60, bringing plunger 55 rearward, drawing bolts 8 and 9 from their keepers; a suitable key is inserted in the opening 71 and turned so as to swing the locking lever 67 away from engagement with the lug T0 and then further rotated so as to slide the stop 6% upwardly, which movement will bring the projection 65 in the path of the forward end of the plunger 55. Figs. 1 and. 2 show the plunger 55 in its locked and unlocked posi tions respectively. When the plunger 55 is in its locked position it is only necessary to again insert the key into the opening 71 and turn said key in the opposite direction to release the locking lever 6? from the lug and slide the projection 65 out of the path of the plunger. The inwardly projecting flanges 72 guard the interior of the casing 6 and prevent foreign substances finding their way therein. The lugs 73 act as guides for the sliding steps 27 and 28.
It is thought that the foregoing description, in connection with the accompanying drawings will suffice to a clear understanding of the construction of my improved lock, the operation of which is as follows: The controlling door carrying the bolts 8 and 9 is first brought to a closed position, in doing which said bolts override the outer plates of the keepers 42. dropping into said keepers. Because of the manner in which the bolts 8 and 9 are connected to the latch heads 7 the movement just described does not affect the mechanism carried within the casing 6. The draw rods 46 work within the yokes 4-7, which in turn have a limited movement within the slots 50. The controlled door being thus adjusted, the master door 11 is closed. In doing this the bolts 5 strike upon the forward edge 4-0 of the casing 6, ride thereover, and project through the openings 41. At the time of the insertion of the bolts 5, the latch heads 7 of the quadrants 51 are in the position shown in Fig. 2, and it will be seen that the bolts 8 and 9 may not be withdrawn from engagement with the keepers 42. It is to be run derstood that before the bolts 5 may assume the extended positions shown in Fig. 2, the sliding stops 27 and 28 must be disposed in their innermost positions as shown in Fig. 1. In order to lock the sliding bolts 5 in their outermost position, as shown in Fig. 2, a key is inserted in the opening 39 and turned, as heretofore described, whereby the sliding stops 27 and 28 will be projected in the path of the lug 16 carried upon said bolts. If it is desired to lock the sliding belts in their retracted positions, the sliding stops 27 and 28 are drawn inwardly, the roll-back 21 turned so as to cause the sliding plate 19 to draw the bolts 5 inwardly, and then the sliding stops 2? and 28 are again forced outwardly in front of the downturned ends 17 of the sliding plate. It may be thus seen that the bolts 8 and 9 carby the controlled door can be locked in their extended positions independently of the sliding bolts 5. The sliding bolts 5 may be locked in their retracted positions, or may be left so as to move freely by actuating the roll-back 21.
It will be readily appreciated that the different parts of my double door lock may be used independently of each. other, that is to say, the master door mechanism may be employed upon a single swinging door. and the mechanism carried by the controllml door may also be used independently of the first mentioned mechanism.
