SPECIFICATION forming part of Letters Patent No. 655,921, dated August 14, 1906.
Application filed December 4,1899. Serial No. 739,148. (No model.)
To @ZZ whom, it may concern.-
Be it known that I, PETER V. GoRNILs, aA citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Locks; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to improvements in locks for doors. lts object is to provide for a compact lock mechanism which is containable within doors having but little thickness, said mechanism comprising a series of springpressed tumblcrs and connected latch mechanism by which the bolt may be prevented from moving except by the use of the key, means by which the outside and inside knobs may be connected or disconnected at will, and Ineans by which the bolt can be prevented from moving either in its locked or unlocked position.
The invention comprises details of construction, which will be Inore fully explained by reference to the accompanying drawings, in whichn Figure 1 is a horizontal section on line m ne ot Fig. 2. Fig. 2 is a vertical section on line to w of Fig. 4. Fig. 3 shows the arrangement when the lock is only used for a night-lock. Fig. 4 is a vertical section on line a' .c of Fig. 2. Fig. 5 is a horizontal section on line y y of Fig. 2. Fig. G is a modification of the lock on line u o, Fig. 7. Fig. 7 is a top view of the same at right angles to Fig. 6. Fig. 8 is a View of the latch. Fig. 9 is a view of the latch used in Fig. 6. Fig. 10 is a detail of the spring which presses on the latch.
The knob-shank is made in two sections A and B, one section having the inside knob 2 fixed to it and the other the outside knob 3. The abutting ends of the two shanks are cnstructed as follows: Upon the part A is the enlarged hollow sleeve 4, into which nts the enlarged end 5 ofthe shank B, so that this end 5 is turnable within the cylindrical sleeve 4. A slot G is made across the end of the part 5, and the correspondingly-shaped plate 7 is slidable longitudinally in the shank A and is normally pressed forward by a spring 8, which forces it into engagement with the slot 6. In this condition both knobs are turnable together, and the locking mechanism may be so disposed that the door can be opened equally from either side. When the door is to be secured so that it can only be unlocked by the use of a key from the outside, the interlocking plate 7 is withdrawn by means of a button 9, which is directly connected with the stem of the plate 7, this button projecting through the end of the knob 2, as shown.
jThe inner end of the button-shank has a slot which fits over a pin 10 when the plate 7 be as many of these tumblers as desired, and `thekeyl has points 14 projecting from it to different len gths,one corresponding with each of the tumblers 12. These tumblers 12 are pressed upon by springs 15, whichnormally press them outwardly.
1G is a latch or block fitting and slidable in a transverse slot 17, made through the two parts of the enlargement 5 of this portion ot' the knob-shank. This block has an opening 18 made through it in the line of the tumblers, this opening being of sufficient size to allow the tumblers to slide freely through the slot. One end of this block 16 is curved, as shown, and the end of the curved portion projects so as to form a pawl 19, which when the parts are in place and the tumblers properly disposed may be projected through slots 20, which are formed through the sides of the hollow sleeve 4 ot' the part A, as shown, and when thus projected the pawl or edge 19, engaging with the side of one of these slots 20, Will turn the knob-shank, and when the outer knob is turned a lug 21, projecting from the sleeve 4, will engage the slot in the slidable latch-bolt 22. This bolt moves in an exterior casing 23, which is '[itted into the edge of the door, so that the outer end ofthe latch-bolt may engage the keeper in the door-j'amb or be retracted therefrom. The normal condition oi' this bolt is to engage the keeper and ICO lock the door by reason of the pressure of the spring 24 upon the rear end of the bolt; but when the lug 21 of the sleeve 4 is turned to engage the notch or slot 25 in the bolt the turning of the'knob will retract the latch and allow the door to be opened. When released, the spring 24 acts to force the bolt outward and cause it to again engage the keeper. The tumblers 12 have transverse slots 26 made in them at diderent distances from the ends, and when these slots are in line with the bridge 27 of the slidable locking-block 16 this block is forced to slide in the slot 17 by means of a spring 28, so as to project the end 19 and cause it to engage with the slots 20, as before described. Under these conditions the turning of the outer knob will turn both the parts B and A of the knob-shank, and the lug 21 on the part 4, engaging the slot 25 in the latchbolt, will withdraw said bolt against the tension of the spring 24. In order to place tumblers in position to allow this block 16 to be moved out into engagement, as above described, it is necessary to insert the key 13, the points 14 of which pressing upon the outer ends of the tumblers l2 will push them in against the tension of the springs 15 until all of the channels 26 are in line with the bridge 27 of the block 16. lVhen the key has been removed, the tumblers are in condition to be pushed outwardly by the action of the springs 15 as soon as the block 16 has been pushed back from its engagement with the slot 2O and so as to bring the opening 18 in line with the tumblers. This is effected by turning the outer knob, when the curved face of the block 16, pressing against the interior of the sleeve, will force the point 19 inwardly against the tension of the spring 28 until the whole of the block 16 lies within the diameter of the part 5. As soon as the slot 18 has been brought into line with the main diameter of the tumblers 12 the springs 15 will act to push the tumblers back through this slot 1S, and this will carry the channels 26 of the tumblers out of line with the bridge 27 and also out of line transversely with each other. It will then be impossible to move the block 16 so as to cause the edge 19 to engage the slots 2O and. any turning of the outer knob will turn theouter portion B of the knob independently and without acting on the inner portion A or upon the locking-bolt 22, which is actuated by the turning of A.
As shown in Figs. 6 and 9, the tumblers, instead of having channels which the key causes to register with the slot 18, are made in three vindependent lengths slidable through holes inthe latch, and when the middle sections are brought by the key to` register with the latch they can be moved with it transversely and out of line with the remaining section.
The two parts of the shank B are guided and held in position, When placed together, by pins 29, which are fixed in one segment and enter holes in the other.
The key 13 has in one side of it a groove or channel 30, which is slidable over a projec-` tion 3l, fixed in one part of the shank B and in line with the path of the key when the latter is inserted. This insures the key being placed in the proper manner when introd uced.
It will be manifest that any reasonable nu mber of tumblers may be employed, depending upon the size of the channel in which they are fitted and movable, and that many variations of the positions of the transverse slots 26 can be made,with corresponding differences in keys as is customary in this class of locks.
The escutcheons 32 may be made concave,as shown, so that if a dooris unusually thin and it is necessary to have the enlargement 4 projecting outside the `thickness of the door it. will be inclosed within the concavity of the escutcheon, through the center of which the knob-shank passes.
In some cases it may be desirable to lock the door from one side so that it cannot be opened from the other. This is effected by the introduction of a screw 33, which is adapted to fit into a hole 34 in the casing 23, in which the latch-bolt 22 slides. "When the bolt is extended and engages the keeper by the'action of the spring 24, if this screw is introduced it passes behind the bolt and prevents its being withdrawn. It it is desired to fix the bolt in its withdrawn position,vthe screw is introduced so-as to engage with the slot 25 ofthe bolt after the latterhas been withdrawn, and it will then retain it in its withdrawn position, which will prevent the door from latching. This condition is useful where a door swings between two rooms and is inconstant use.
When the device is used as a night-latch, the outside knob is omitted and the inside knob gives place to a small turning knobor button. In this construction the knob-shank is turned by the key when the latter has been introduced.
Having thus described my invention, what I claim as new, and desire to secure-by Letters Patent, is-
