I. The invention relatesto locksand parof Fig. 9.
ti cularly adapted to be embodied in the doors of. a dwelling place or the like.
A particular ob ect of the invention 13 to provide an improved lock which will hold a door in its locked position in such manner that the door cannot rattle.
One form of the invention is embodied in a lock which comprises a wedge member carried by'the door and adapted to engage a pivoted member carried by the door frame, the construction being such that when the door is in its locked position, the wedge member gravitates down into a position wherein it firmly engages the pivoted member and holds the door against any movement relative to the door frame. Any force tending to cause some'movement between the dooi' and its frame will cause, the wedgetogravitate a slight distance'downwards .so that it vwill wedge itself deeper into the. pivoted,
member.
' Other objects and advantages will become apparent as the following description progresses, reference being had to the accom panying drawings, wherein:'
- Figure 1 is a section taken on line 11 of showing a lock which embodies another form of the invention, and
Fig. 10 is a sectiontaken on line 10 10 Fig. 11 is a view similar to Fig.1, but
Fig. 12 is a section taken online 12-12 of Fig ll.
Referring for the present to Figures '1 to 8 inclusive, wherein a preferred. embodiment of the invention is illustrated, the reference character 10 designates a door which is mounted in a door frame 11 by hinges (not shown). The door 10 is equipped with the improved lock which is designated generally by the reference character 12. I
The improved lock 12 comprises akeeper 5 which is pivoted by a pin 16 in a housing member 17 the member being fixedin a recess 18 provided in the door frame 11. A a spring 19 wound around a pin 20'tends to rotate th'e keeper 15 in a clockwise direction (Fig. 2) so that the keeper 15 will occupy the position wherein it is shown in Figure 8 when the'door is in its open position. v
\The keeper 15 is pivoted intermediate its 7" ends and comprises arms 22 and 23, thearm' 22 being engaged by a wedge member 25 Fig. 2, theview being taken from the inside when the 0 is in w p s of a door which is provided with a lock embodying the invention. I

Fig. 7).
The wedge member 25 is slidably journaled The housing As best shown in Figures 1 and Gthe'wedge,
member 25 is provided with a vertically extending slot '35 into which the free end of p a lever 36 projects. The lever 36 is fixed 9 to a pin 37 which is rotatably journaled in the housing member 26 and a plate. 38, the plate 38 being fixed to the inner side of the door 10. 'The usual door knob or handles 40 and 41 are fixed to the outer and inner ends, respectively, of the pin 37 and it is readily understood that the door knobs 40 and 41 may be rotated to angularly displace the lever 36 in a clockwise direction (Fig. 1) to .lift the wedge member 25. A helical spring 44 yieldingly urges the lever 36 in a counter-clockwise direction (Fig. 1).
Secured to the inner side of the portion 28 is a bracket member 46 which carries a vertically disposed pin 47. Pivoted upon the pin 47 is a member 49 which is yieldingly urged in a clockwise direction (Fig. 2) by a spring 50. The construction is such that when the door is in its closed position, the arm 22 of the keeper 15 projects through a slot 52 formed in the portion 29 of the housing member 26 and holds the member 49 in the position wherein it is shown in Figure 2 so that it does not interfere with downward movement of the wedge member 25. However, when the door 10 is opened, the keeper '15 swings into the position wherein it is shown in Figure 8 and withdraws the arm 22 through the slot 52 so that the spring 50 will angularly displace the member 49 into a position wherein it lies against the inner side of the portion 29. This closes the slot 52 and also brings the member 49 into a position wherein it is disposed beneath the wedge member 25 and prevents downward move ment thereof.
It may be mentioned at this point in the description that when .the door is in its closed position, the wedge 25 urges the arm 23 into engagement with the outer side of the housing portion 29 and engages the arm 22in the manner illustrated in Figure 3. The weight of the wedge member 25 prevents it from moving upwardly and therefor the wedge member 25 looks the keeper 15 in the osition wherein it shows in Figure 2. en the keeper 15 is in this position, the door is held firmly against movement relative to the door frame and any force tending to swing the door on its hinges will only cause the wedge member to drop lower so that the door is held more firmly against movement relative to the door frame.
The lock 10 comprises and is controlled by a tumbler lock which is designated generally by the reference character 55. The tumbler lock 55 comprises a housing 56 which is rigidly secured to the plate 26 (see Figure 4). Surrounding the housin 56 and slidably mounted thereon, is a late member 57 which comprises an upwardly extending arm 58, provided with a lug 59. The lug 59 functions as a stop member for the lever 36 when the latch member 57 is in the position wherein it is shown in full lines in Figure 4. However, when the latch member 57 is displaced to the right (Figure 4) into the position wherein it is shown in dotted lines, the lug 59 is withdrawn from the path of the lever 36 and that lever may be singularly displaced to lift the wedge member 25. Accidental displacement of the latch member 57 along the housing 56 is prevented by means comprising a ball 60 adapted to engage depressions 6'1 and 62 formed in the outer surface of the housing 56. The ball 60 is urged into these depressions by a spring 63 -carried by the latch member an movable therewith. When the latch member 57 is in the position wherein it is, lug 59 is disposed in the path of the lever 36, the ball 60 engages the depression 61, but when the latch member 57 is "moved into the position wherein it is shown in dotted lines in Figure 4, the ball 60 engages the depression 62. It is readily understood, of course, that the spring 63 will yield to permit the latch member 57 to be forced from one of itspositions into the other.
It will be noted that the housing member 56 is shaped so that the latch member 57 cannot be angularly displaced around the housing 56. A bar 66 secured to or formed integral with the latch. member 57 is provided with a finger piece or knob 68, which is accessible from the inner side of the door 10, the knob 68 being disposed conveniently with res ect to the knob 41.
plug 7 0 is slidably j ournaled in the housing 56 so that it may be displaced toward or away from the outer side of the door. The plug 70 is held against rotation around its axis by a lug 71 which travels in a slot 72 provided in a housing 56.
A plurality of tumblers 73, slidably-mounted in the housing 56 co-operate with a plurality of tumblers 74, slidably mounted in the plug 7 O to lock the plug 70 against movement in the housing 56 when the plu is in the position wherein it is shown in fufi lines in Figure 4. It is readily understood, however, that when a key 75 of suitable conformation is inserted in a keyhole 76 provided in the lug 70 (see Figure 4), the tumblers 73 and 4 will be brought .into positions wherein they permit one to push against the key 75 to displace the plug 70 toward the inner side of the door. Such displacement of the plug 70 will displace the bar 66 in the same direction and the bar 66 will, of course, draw the latch member 57 with it so that the lug 59 will be withdrawn from the path of the lever 36. The knob 40 may be manipulated then to cause the lever 36 to lift the wedge member 25. Such displacement of the wedge member 25 unlocks the door 10 so that it may be opened. When the door is opened in this manner, the keeper 15 rotates into the position wherein it is shown in Figure 8, so that the arm 23 will be engaged by the door during its final closing movement. Meanwhile, as long as the door is open, the latch member 25 is held in its upper position by the member 49, against which the wedge member rests.
When the door is moved into its closed powishes to open the door from the'outside thereof. To open the door from the inner side thereof, it is only necessary to pull upon the knob 68 which will operate through the bar 66 to displace the latch member 57 into the position wherein" it isshown in dotted hnes in Figure 4, whereupon the knob .41 may The manipulated to ,angularly displace the lever 36 so that it will lift the wedge member 25. The door may be locked at any time by pushing upon the knob 68 so that the plug 70 is displaced into the position wherein it is shown-in full lines in Figure 4. When-the plug isin this position, and the key 75 is not occupying the keyhole 76, the tumblers7 3 and 74100 the plug against movement relative to the housing 56.-
As best shown in Figure 4, the tumblers 73 are-of different diameters and each tumbler 74 is of thesame diameter as its co-operating tumbler 73. The purpose of this construction is to prevent the tumblers 73 from falling into the wrong apertures in the plug 70.
' Briefly, the operation of the above described apparatus is sfibstantially as follows: If it is assumed that the door is locked in its closed position, one may unlock the door by inserting the key 75 in the keyhole 76 and then push upon the key 75 to. displace the plug 70 andthe latch member 57 until the lug 59 clears the lever 36. The knob 40 may then be otated to have the lever, 36 lift the wedge h -member 25 out of the path of the keeper 15,
whereupon the door maybe pushed into its open position. Then as one enters through the door, the key 75 may be withdrawn from the keyhole 7 6, but the lock will remain in its unlocked condition. Then if one wishes to lock the door in its closed position, it is necessary to push upon the knob 68 as described above. The door may be unlocked from the inner side thereof by pulling upon the knob 68. The latter operation does not require the use of the key 75.
Referring now to Figures'9 and 10 wherein another embodiment of the invention is illustrated, the reference character 110 designatesgenerally a lock which has many parts which are identical in construction with similar parts in the lock 12 described above. The lock 110 is'particularly adapted for use on clothes-closets or the like and may be operated only from the outer side of the door. In Figures 9 and 10, the parts which are identical in construction with certain parts of the lock illustrated in Figures 1 to'8 inclusive,
.has been inserted in this manner,
are identified by the same reference numerals. Thus, the lock 110 comprises a lever 36, the wedge member 25- and a keeper which function in the same manner as the same parts function in the lock' 10. The wedge member 1 is retained in its upper position by amember 49 when the door 1s opened. In Figures 9 and 10, the door isindicated at 109 and the associated arm is indicated at 111. J
The lock 110 comprises and is controlled by a tumbler lock 155 which resembles the lock in construction. The lock 155 comprises a latch member 157 which is slidabl v mounted upon ahousing 156 which is pre erably rectangular in cross section. An arm 158 formed integral with latch member 157 is provided with a lug 159 which has the same function as the lug 59 described above. Slidably journaled in the housing 155, is a plug 170 which has tumblers (not shown) adapted to co-operate with the tumblers (not shown) provided in the housing 156. A suitable key may be inserted in the keyhole 176 formed in the plug 170 to. bring the tumblers (not shown) into positions wherein they permit displacement of the plug 170 relative to the housing 156. When the key" (not shown) one may pull upon the knob 168 securedto the latch member 157 and the olug 170 to pull the latch member and the plug toward the outer side of the door 110 so that the lug 159 is with"- drawn from the path of the lever 36. The lever 36 may then be angularly displaced by manipulating a suitable knob (not shown) provided upon'the outer side of the door.
The door may be locked by pushing against the knob 168.
Still another form of the invention is i1 lustrated in Figures--11 and 12 wherein I have shown a lock 212, adapted to lock a door 210 to a door frame 211. The lock 212 is identicalin construction with the lock 12 described above with the exception that the tumbler lock 55 is replaced by a tumbler lock 255, which controlsthe operation of the lever 36, which lever has the same function as the lever 36 described above.- Similar parts of the locks 12 and 212 are identified by like reference characters.
Tumbler lock 255 comprises a housing member 300-in which a plug 301 is rotatably' journaled. Tumblers 304, provided in the plug 301 co-operate with tumblers 305 pro vided in the housing 300,-the construction being such that when a key 306 is withdrawn from a keyhole 307,. provided inthe plug, the tumblers will prevent rotation of the plug in the housing. Secured to or formed integral with the inner end of the plug 301 is a lever 308 provided with a'plug 309 which placed to have it raise the associated wedge member 25, whereupon the lock 212 will function in the same manner as the lock 12 described above.
It may be mentioned that the lever 36 V is fixed to a pin 37 which is identical in construction with the pin 37 described above and is provided with knobs 40 and 41 having the same functions as the knobs '40. and 41 shown in Figure 1.
