To all whom it may concern: 7
- Be it known that I, LOUIS MEYERS, a citi- .zen of the, United States of America, residing at Brooklyn, New York, have invented new and useful Improvements in Locks, of which the following is a specification.
This invention relates to looks. v
The object of the invention'is to-provide a lock which has a curved bolt which may be. rocked so as to engage or become disengaged from a keeper, having a curved opening therethrough, and arranged adjacent to the look. A further object is to provide such a lock with means whereby it may not be operated by a key from the outside if desired. A further object is to provide a construction which will cooperate with the common form of barrel, such as is usually found in the type of locks known as cylinder locks. I
The invention consists of the construction,
combination and arrangement of parts, as
herein illustrated, described and claimed.
In the accompanying drawings, forming part hereof, is illustrated a'form of embodiment ofthe invention, in which drawings 7 similar reference characters designate corresponding pa'rts, and in which? Figure 1 is an inside elevation, showing the door and the door-j amb, the keeper being shown in section andthe bolt of the lock retracted; 1
Figure 2 is an edge elevation of the door, showing the lock in end'elevation;
Figure 3 is an outsid elevation of the door, showing the projection, slotted endof the lock casing; i
Figure 4 is an elevation of the inside of thelock, a portion of the back cover being removed;
Figure 5 is a vertical section taken approximately on the line 5-5 of Figure 1, looking towards the left hand;
Figure 6 is a vertical section'taken approximately on the line.55 of Figure 1. looking towards the left hand, the parts being arranged in this figure so that the bolt of the "lock will not be operated by a key inserted in the barrel; and,
Figure 7 is an elevation of one end of the lock casing showing the means for preventing the bolt being operated by a key, such means being shown in operative position.
Referring to the drawings,
1 designates the door into which is set the usual form of-barrel' 2, which barrel may be of the usual cylinder'type and contain' mechanism operated by a key'so that th squared spindle 3 of the barrel may be turned by the operation ofthe key. All of this mechanism is of the well-known type and'is" not claimed as a part of this invention, except in so far as a patentable combmation may exist between it and the following described construction.
Secured on the door 1, onits inside face,
is a casing 4, having a back cover 5 removably held in osition by means of screws 6 and also provided with a slotted end 7, which projects beyond the edge of the door 1- and is adapted to receive the keeper hereinafter described when the door is closed. 1
' Disposed in the casing 4 is a segmental gear 8 having a curved,projectingportion 9 which forms the bolt of the lock. The
segmental gear is arranged to rotate on a pin '10 extending transversely of the casing 4. A pinion 11 isdisposedin the casing and arranged to mesh with thegear 8,'and is mounted on a sleeve 12 which projects through one wall of-the casing 4 and terminates in a knob 13, provided'with a shoulder 14. A spring 15 is disposed around the sleeve 12 so that one of its ends bears against the pinion 11 and its opposite'end bears against an adjacent portion of the wall of the casing 4, so that the pinion and knob are normally maintained in the position shown in Figure 5, that isltosay, in the position whereby the bolt may be retracted by the use of a key.
A sleeve 16 is provided with a' squared bore and arranged to receive the squared spindle 3 and, as byrmeans of a washer or turned over end 17 ,gis maintained on the back cover 5 so thatit is free to rotate with relation to the casing. The sleeve '16 is ofslightly less diameter than the sleeve 12. so
thatthe sleeve 12 may slide longitudinally thereof freely. 'i 1 Disposed on the sleeve 16 and fixed thereto isawasher 18, provided with a' lugr' 19 arranged in the path of movement of the pinion 11 and so. arranged as to engage into an opening 20 formed in one face of the pinion, when the pinion is forced to the position shown in Figure '5. V
A pivoted finger 21 is disposed on the outer wall of the casing 4 and is arranged to be rocked to the position shown in Figure 6 in order to hold the parts in the extended 28 adjacent the door.
the 'casing' l. The keeper '23 may be maintained inposition by any suitable mechanical means, such as the plate 25, screws 26,
and 1a through bolt 27,'fixed to the jamb In the o eration of the device,'a suitable key being inserted in the barrel 2, the
squared spindle 3 thereof maybe rotated. With the parts in the position shown in Figure 6, the sleeve 16 will be rotated without rotating'the pinion 11, because the lug 19 is then disengaged from the opening 20 of the pinion. Theparts being in the posi- ,tion shown in Figure 5, under the tension of the spring 15, the pinion 1]. forced to the right hand and the lug 19 engages in the opening 20 0f the pinion so that rotation of the squared spindle 3 causes rotation of the, PiIIlOIllil-u From inspection of Figure i, itwill be apparent that rotation of the pinion 11 will cause-rotation of the gear 8 on its pivot 10, so that theprojecting end 9 of the segmental gear 8 would pass through the opening 24 ofthe keeper 23. v
- Having thus fully described the invention, What is claimed as new and desired tobe securedbyfiLetters Patent is: 1
.1. A lock comprising the combination of a keyoperated rotatable squared spindle, a rotatable sleeveprovided with. a squared bore arranged to receive the spindle; a second sleeve slidably disposedon the first sleeve, means for normally maintaining the two sleeves locked together, agbolt arranged to be rotated by rotationotone of i the sleeves, and means for maintaining the two sleeves in unlocked position to permit the'rotation of one sleeve without 111OV6- ment oflthe bolt.
'42. A look comprising the combination of" a keyoperated rotatable squared. spindle, a sleeve provided with a squared bore into. which the spindle is set, a washer secured on the sleeve and provided with al'ug,'a'
pinion slidably disposed on the sleeveand provided with an opening arranged to receive the lug, means for moving the pinion longitudinally of the sleeve, and a rotatable bolt arranged to be operated by the pinion.
'3. A lock comprising the combination of a key operated rotatable squared spindle, a sleeve provided with a bore coincident with the spindle and into which the spindle is set, a washer secured on the sleeve and provided with a lug, a pinion slidably disposed on the sleeve and provided with an opening arranged to receive the lug, means for moving the pinion longitudinally of the sleeve, means for normally maintaining the lug 1n the opening in the pinion, and a the pinion. r
