Specification of Letters Patent.

MULTIPLE-BOLT DOOR-LOCK.

' Patented m 4., 1916.

Application filed April 14, 1916. Serial No. 91,088.

To all to hom it mayconcem Be it known that I, PETER MUGLER, a citizen of the United States, residing at Sisson, in the county of Siskiyou, State of California, have invented a new and useful Multiple-Bolt Door-Look; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as' will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the art of locks, and latches, and more especially to a screw multiple bolt door lock, and an object of the invention is to provide a simple and improved, eificient and practical lock of this kind comprising a pair of members pivotally mounted substantially at right angles to each other upon a single pin and detachably connected to each other to operate simultaneously, whereby they may be oscillated or rocked by a single key, for actuating a plurality of bolts into and out of engagement with their keepers.

A further object of the invention is to provide means for locking said plurality of bolts either in engagement or out of engage. ment with their keepers.

The object for locking the bolts into engagement with their keepers is to prevent an instrument of some kind from being inserted bet-ween the door jamb and the door sufficiently to actuate one bolt which in turn will actuate the others, that is, upon the exterior of the door.

The object for holding the bolts locked out of engagement with their keepers, is to prevent the bolts from being moved to open positions, which would cause the ends of the bolts to jam against their keepers, when the door is thrown to a closed position. A lock of this kind is applicable to any style of door, preferably large. or heavy exterior doors of banks and the like and large public buildings.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in elevation of a door, showing the application of the improved multiple bolt look as applied. Fig. 2 is a plan view of the lock with the cover removed, illustrating the bolts retracted. Fig. 3 is a plan view with the cover removed, showing the bolt thrown. Fig. 1 is a plan view of the lock with the cover in position, and the bolts illustrated in dotted lines as having been thrown, and the rocking means upon the inner face of the cover holding said'bolts in such thrown positions. Fig. 5 is a plan view of the cover showing the same inverted, to illustrate the rocking means for holding the bolts thrown into locking position. Fig. 6 is a sectional view on line 6-6 of Fig. 4:. Fig. 7 illustrates perspective views of the rocking members having loops for engagement with the pins of the bolts for operating the same, and illustrating the construction of the connections between the members. Fig. 8 is a detail view in elevation of thekey for rocking the members illustrated in Fig. 7. Fig. 9 is a sectional view on line 9-9 of Fig. 8.

Referring more especially to the drawings, 1 designates a suitable door, which is hinged at 2 to the frame 3. Carried by the door and secured thereto by the screws 4 is a casing 5, consisting of two sections 6 and 7. The section 6 is disposed adjacent the face of the door and is provided at its corners with angular corner plates 8, which extend out and overlie the section 7 of the casing, thereby preventing lateral movement of the sec tion 7, that is, prior to securing the section 7 by means of the screws 9, which are threaded into the bosses 10, thereby securing the section cover plate 7 securely in place. Rising upwardly from the center of the section 6 is a stud pin 11, on which the rocking or oscillating tumblers 12 and 13 are mounted. These tumblers consist of cylindrical portions 14 and 15 having'looped projections 16, 17, 18 and 19, and these tumblers are arranged relative to each other upon the stud pin 11, so that the looped projections of one tumbler will extend at right angles to the looped projections of the other tumbler. The cylindrical portion 1 1 of the tumbler 12 has its upper portion provided with diametrically opposite notches or recesses 20 positioned at right angles to the looped projections 16 and 17. The under face of the cylindrical part 15 of the tumbler 13 is provided with diametrically oppositely disposed'lugs 21 to engage the notches or re cesses 20, thereby holding the two tumblers at right angles to each other upon the stud pin 11. The upper face or portion of the cylindrical part 15 of the tumbler 13 is provided with diametrically oppositely disposed Will lugs 22, the purpose of which will appear later. The flanges of the sections 6 of the casing are provided with guide recesses 23, in which the sliding bolts 24 and 25 are guided. The sliding bolts 24 slide or operate horizontally and are designed to enthe keepers 26 of the vertical'jambs of the door frame 3. The bolts 25 slide or operate vertically, and their upper and lower ends are designed to engage the keepers 27 of the sill 28 and the top jamb 29 of the door frame. Each of the bolts consists of the two sections 30 and 31 connected together by the screws 32. The bolts are guided in the straps 33, which. arch the bolts, and are secured to the door 1. One of the bolts 24 operates below the cylindrical part 14 of the tumbler 12, while the other bolt operates above the cylindrical part 14. One of the bolts 25 rec'iprocates vertically upon one side of the cylindrical portion of the tumbler 13, while the other bolt 25 operates vertically upon the opposite or left side of the cylindrical portion 15 of the tumbler 13. The bolts 25 cross over the bolts 24, and are additionally guided in the U-shaped guide 35, which extends laterally from the inner face of the section 6 of the casing 5. The upper and lower flanges of the section 6 of the casing 5 have secured thereto in any suitable manner overhanging lugs 36. The inner end of the sliding bolts 24 and 25 terminate in laterally extending lugs 37, which contact with the U-shaped guide 35, when the bolt is thrown outwardly, thereby limiting the same in their movements. The inner ends of the bolts 25, when retracted contact with the lugs 36, thereby limiting said belts in their movements inwardly. However, when the bolts 24 are retracted, their inner ends contact with the vertical side flanges of the section 6 of the casing 5, so as to limit the bolts 24 in their inward movements. The under faces of the inner portions of the bolts 24 are provided with downwardly extending lugs 39, which. engage the elongated openings of the looped projections 16 and 17 of the tumbler 12. The upper faces of the bolts 25 are provided with lugs 40, which engage the elongated openings of the looped PlOJG-CtlOTlS 18 and 19 of the tumbler 13.

A suitable key 41 is illustrated in Fig. 8 comprising a knurled head 42 and a shank 43 having a cylindrical bore 44, which telescopically receives the stud pin 11, wh1ch projects beyond the cylindrical portion 15 of the tumbler 13. The shank 43 of said key 41 at its end is provided with diametrically oppositely disposed notches or recesses 45, which are designed to receive the projections or lugs 22, when the stud pin 11 telescopically enters the bore 44, so that by rocking the key in one direction or the other, the tumblers are correspondingl rocked simultaneously, whereby the bolts 24 and 25 may be thrown outwardly or retracted. One edge of each bolt near its inner end is provided with a notch 46. The cover section 7 of the casing 5 is provided with a central opening 47, and a pair of diametrically oppositely disposed segment slots 48. A knurled knob 49, which is in the form of a ring is disposed upon the outer face of the section 7 of the casing 5. The central opening in the ring to the opening 47. A plate having four radial arms 51. is arranged adjacent the inner face of the cover section 7, and has a central opening registering with the opening 47. one face of the knob 49, and pass through the diametrically oppositely disposed slots 48, and through the plate 50 and have their inner ends riveted, so that by turning the knob in one direction or the other, the plate 50 will rock with the knob. The extremities of the arms 51 of the plate 50 terminate in angular flanges 54 having lugs It is to be noted that when the bolts 24 and are retracted into the casing 5, that is, their inner ends, the notches 46 assume such positions that the lugs will engage them, that is, when the plate 50 is rocked from its dotted line position in F 5 in the direction of the arrow (4, to the full line sition, thereby preventing the bolt from being thrown outwardly. However, when the bolt is thrown outwardly, the lugs 55 of the flanges 54 will assume positions in the path of the inner ends of said bolts 24 and 25, thereby preventing the bolts from being retracted, by an instrument being inserted between the door jamb and the door. In locking and unlocking said bolts against movement, the plate 50 is rocked in the same direction in both instances. Upon the under face of the cover section 7 of the casing lugs are provided, arranged diametrically opposite each other, and designed to be engaged by the arm 51 of the plate 50 to limit the plate 50 in its rocking movement.
