LOCKING DEVICE.

ToaZZwwmit mag/concern:

-Be it known that I, ARTHUR, rREGINALD COLLIER, .asubject of the King4 of Great Bri-tain and Ireland residing' at '64 Brownlowiload, New Southgate, MiddleseX,"Eng-. land, .have invented rnew and `useful Improveniente in4 and Relating' to Locking Devices, of-.which the 'following-is a specifi cation. i

My Yinvention yrelates to fa lock, operated from a common centre, for securing a door (ar-.the like lat three or more places, and designed for use on the outside doors of private houses, dilate, shops, warehouses, churches, kgarages and other places liable to bede-,tt -at times without an occupant. The invention is also applicable for use on the doors of-strong-rooms, store-rooms and the like.

`Broadly stated the invention comprises a lockffor securing a door or the like at three or more points, which when secured by the turrringof a handle yor knob. on the outside of the door can only be` operated fronrthe outside by means of a key and cannot be operated from the inside by any means.

According to the 'invention' a horizontal sliding bolt is adapted to normally project in front of the lock case and bevelled or rounded Aon one side of the projecting' end in the ormof an ordinary latch bolt. This latch bolt is combined with an'inner horizontally sliding member contained entirelyV within the lock case and'two or more vertically sliding` bolts respectively adapted to engage when moved to the locking position in .staples or boxes arranged in the door frame above and below the door.

The combination of bolts is operated and controlled.` by a key and inside and outside knobs or handles and is so arranged 'that by closing the :door and turning a knob ont the outside of the door, itis secured in three or more .places and cannot be opened by any means Yfrom inside, and only by the use of the key Jfrom the outside. Thile by closing the door and turning the knob on the inside and by securingthe vertical bolts at top and bottomby additional locking means the door is secured in three or more places and cannot be opened'from the outside by any means, but can be opened from inside by first releasing the vertical bolts at top and bottom and then turning the knob or handle. When theivertical bolts are drawn and the lock is in normal on the latch position,

the door may be freely opened from both `inside'and .outside by turning the knob but the verticalbolts cannot be operated.

The invention is illustrated byway of example in the yaccompanying drawings, `in which- 'Y i Figure 'l shows thelock 'with its parts in the lnormal on the latchL position with the vertical bolts drawn.

Figure 14: shows an alternative form of lock in which the latch bolt can be withdrawnby the key vthrough the inner sliding member, and

EFigure 15 shows an alternative form. of the actuating cam on the inside member of the ,divided spindle.

Referring now to the vrdrawings a pair of vertically sliding bolts l (Figure 6) are operated from one or both sides oi the door by means of knobs or handles 2 fixed u on a divided spindle (Figure 9) and when s ot engage in staples 3 as shown. or boXes or the like fixed on the door frame 4 or in recesses provided in 'the same. The divided spindle which is shown in detail in Figures 7 and 8 is employed to allow the inner knob or handle to be turned to a certain distance to draw the latch bolt 5 when the outer knob or handle is locked by cam 6 on its part of the spindle engaging the butt end of a stop 7 and thus preventing further movement of the cam 6 until the stop is lifted, shown in Figure 1. rlhe horizontally sliding latch bolt 5 assumes a latching or halt' throw position limited by a removable stop 45 or a full thrown or locking position when said stop is removed due to projection by its spring 9 engaging the lug 90 carried by the said bolt 5. Slidably nested on the latch bolt is a plate or inner bolt member 8 carrying a lug 18 and projectable by a spring 10 engaging another lug 100 carried by the said member 8 to move the lug 18 into a notch 19 in vertical bolt 1 when said bolt is moved to locking position to bring notch 19 in registration with lug 18. The inner bolt member 8 is operated by means ot a suitable key spindle 11 fitted with suitable operating means such as 'cams 12 (as shown), cogs, spokes or the like engaging with correspondingl cam members 13 projecting from the wall ot a central recess 14 in the said sliding member 8. This key spindle 11 is adapted to be turned from the outside of the door by the key only. The key operated gear itself forms no part of this invention and may be ot any suitable form. convenient for the thickness of the door on which the lock is mounted. The portion oit the dividedv spindle (Figure 7 connected directly with the outside handle operating the vertically sliding bolt 1 is fitted with cams 15 as shown, or cogs, spokes or the like, so arranged that when the spindle is turned by a knob or handle trom the inside or outside ot the door the cam members 15 engage in correspondingly shaped recesses 16 on the sides ot the vertical bolts, and cause said bolts to travel in opposite directions, As shown in Figure 3 one ot these vertically sliding bolts 1 is so Jformed that when in the withdrawn position a shoulder 17 thereon engages with a shoulder 18, Figure 5, on the key operated hori- Zontally sliding member 8 and holds the latter in position against its spring 10. Upon turning the outer handle or knob in order to shoot the vertical bolts, the bolt 1 with thev shoulder 17 travels to a position in which a recess 19 therein is in alignment with the shoulder 18 of the key operated sliding member 8 thus allowing the same to move forward under the iniiuence ot its spring 10 and its shoulder 18 to pass into said recess 19 and to hold the vertical bolt and consequently the opposite vertical bolt 1 firmly locked against operation by the cams 15 mounted on the divided handle spindle. When the bolts 1 are thus shot the door is secured at the top and bottom and at the side by the latch bolt 5 and can only be opened by the use ot a key :trom the outside to turn the spindle 11 through which the sliding member 8 can be withdrawn to a position in which the shoulder 18 is clear oi' the recess 19l in the upper vertical bolt.

-The channel 4() above the shoulder 17 in the bolt 1 receives the flange 41 of the latch bolt 5, (Figures 1 and This iiange 41 normally rests in this channel when the latch bolt is in the on the latch position and so prevents the bolts 1 trom being shot until theA sleeve portion of a spring controlled vertical stop 24 has been withdrawn from the latch bolt 5 on the inside ot the door by the person opening the door through an actuating arm 42 outside the lock casing.

lThe crank projection G on the portion directly 4connected with the outside handle of the divided spindle engages in the V between the

members

20 and 21 of the inside portion as shown in Figure 9. These

members

20, 21 are arranged so iar apart that when the spindle connected with the outside handle has been revolved beyond the point necessary to withdraw the vertical bolts 1 the inside part ot the spindle (Figure 8) can still be turned a suiiicient distance in said V ttor its cam member 22 to engage the end o't the lever arm 23 which is in alignment with the sliding latch bolt 5 and to withdraw the saine against the iniiuenrc ot the spring 9 to aposition in which it is clear ot the box on the door trame. Then the outside handle is turned to withdraw the bolts the projection 6 on the outside part ot' the spindle is adapted to litt the vertical spring` controlled stop 45 into engagement in recess 25 in the sliding member 8 and the latch bolt and thus holds both in their normal positions in the lock casing, with their springs 9 and 10 partially compressed. This double stop formed by the pin 24 and sleeve 45, and the crank 6, is lurther controlled by an outdoor latch stop 7 best seen'in Figure 4. rPhe stop slides in a boss 48; it has a head 27 by which it may be withdrawn trom inside the door against the action out a spring 49 compressed between the end of the boss and the transverse pin 50 in the stop; this pin further engages a groove 51, shown as a spiral groove in Figure 4, and so serves to retain the stop in inoperative position against the action ol the spring.

The action ot the apparatus may be seen trom Figures 1, 2 and 5.

1n Figure 1 the parts tre shown in the indoor latch position. The bolts 1 are withdrawn, the Vtlairge 41 is engaged in the recess 40 ot the upper bolt and so prevents the bolts being shot. lt either handle is turned the latch cam 22 will rotate the lever and partially withdraw the latch bolt 5. Betere it fully withdrawn the crank (i abuts upon the out-door latch stop 7 and the outdoor handle cani be no iurtherlturned;

hence the door cannot be opened from outside. .But on account .of the lost motion between the crank 6 andthe V 20, 2l, `the indoor handle can be turned a little further, suiiiciently nto 4withdraw the .latch bolt 5 wholly from its socket.

It the stop 7. is withdrawn by rotating the head 27. there is no obstacle to movement of the cam; 6; except'the .offset portion of the stop 24; moreover, this stop can be lifted by the crank .against the action of spring 46. 1n this condition, therefore, the-latch can. be withdrawn from indoors or outdoors. V

If; the partsare in the indoor latch position and the occupant .proposes to leave the house `torsorne time, .and desiresV to .leave it safely locked, .his iirst action is to pull down the fingerlpiece 42,Y so withdrawing 'the latch bolt stop 45 fromitheslot 2,55. The spring 9 'being `already in compression will thrust forward: the latch bolt sutiiciently to carry the lange 41 .out `oi? the slot40 of bolt l. The bolts-arethenfree to be shot. Next the stop 7 `is withdrawn; the compressed spring 46 at once thrusts down the stop 24, so withdrawingit from the; recess 25 4in the member S. Theoccupant then leaves the house, closes the door and shoots the bolts 1, by rotating the outdoor. handle. As soon as the recess 19 in the upper bolt comes opposite the shoulder18 oi the member 8 the member will move :forward under. the action of. itsspring 10. and engage the shoulder in the recess. Thus the bolts are locked in shot position. Thisl occupant absent condition is shown in Figure 2. .The door .cannot now be opened Ytrom inside at all, .and can. only be opened from outside by the use of the proper key. To open `it the spindle 11 is turned by the aid ot the key, so that the cams or lugs 12 withdraw the member 3 against the action oi spring 10. When it has moved so far that the shoulder 18 is clear `of the upper bolt the two vertical volts can be withdrawn by rot-atingf'the` outdoor handle. At the end of this motion. the cam 22 engages the lever 23 and-withdraws the latch. There is no obstacle to the passage of crankv 6 except the ol'fsetpart of `the stop 24'; and since member 8 has been withdrawn so that its recess handle. As a iinal security to prevent the bolts being withdrawn from outdoors he engages lthe hinged members 30 with the slots 31 in the `bolt-s. -This is the occupant within condition. In Figure 15 I show an alternative form of the cam 6 which enables the outside handle to be lockedirom movement in either directionby means ofthe stop?. In thisform a curved recess 43 is provided in the engaging face of the cam 6 adapted vto receive. the stop 7. This curved...recess.43.is deep enough-tor its extremity 44 to engage the stop ran'dyto prevent the outside handle iromubeing turned in either ldirection lwhen thestop is in. position in said recess. `The stop 7 can be put "out `of actionl .to'enable the door to be openedby the .outside .handle .2 from the on the latch position. Any su-itable means may be employed to retain this stop 7. in the free position out off-action such for instance, as shown in= Figure 13, infwhich aflateral pin 28 can .bearranged to engage in abayonet channel cut in `thewafll :ofthe sleeve 29 enclosing the stop and operating spring.y When the door is lbolted from the inside, the vertical Abolt can-.befurther securediat the topand bottom of the door-.by a

hinged member 3() on the .braclet132 adapt-ted l to engage in one .or other. of. the-*recesses 3l at the extremities of the bolts 1.' The bracket 32 is fixed in a suitable position vto the face of the idoorand the member'BO is adapted to engage the upper recess 31 .whenr'the boltlis in the withdrawn position and thelower recess when the `bolt has been shot. Anyequivalent ldevice can be used.

In'lzigure 141 show Ian alternative 'form offlock for use -in premises such asdwelling houses in which itis convenient Y' tofallow oi the-inner slidingmember `Shaving a longer rearward travel the recess 25 :and slot y255 being elongated 'for this purpose, so` as to admit of the complete withdrawal of the latch rbolt 5 by the key alone when the latter is in the on'theylatch or normal position. .This arrangement allows of the house being entered byv more than 4one person provided with duplicate keys. Intl? igures 11 and 12 Ishow by way of example two methods ofsecuring a Idoor` at more than three places. In Figure 11-1 show two views in whichV one or more additional sliding bolts 35 are slidingly fixed on the side ot' the door and are operated bythe curved part '36 of the vertical iboltil which nirved part operates said 4bolt 35 through the pins 37. In the upper 7figure the bolt35 is shown withdrawn while' in thev lowery .figure it is shown in engagement with fthe staple38 on the-door `frame. In the alternative form l'shown in Figure 12 the bolts 35- are pivoted to the vertical bolts 1Jand to the ydoor at 39Y so that as said bolts 1 rise and fall the bolts 36 are shot or withdrawn siO'nal fashion.
