RECORDING-LOGK CONTROL MEANS.

Application filed August 17, 1926. Serial No. 129,811.

My invention relates to looks, more particularly to recording locks in which a record is made when the lock-bolt is thrown, as for instance in recording locks of the a type illustrated in Patent No. 1,112,.l19 granted to me Sept. 29, 1914, and other patents of the same general type granted to me, which are selected as an illustration of a type of recording lock to which the pres- Hi out invention may be applied without however restricting the present invention to such particular type of looks. The present invention has for its general object to provide control-means that will prevent the lockbolt being thrown until permitted by such control-means, the control-means and the lock-bolt actuating means being independently operated so that one may be under the direction of one person and the other under 2- the direction of another person, so that the act of two persons is necessary for effecting the unlocking of the lock-bolt and thus one will be a check on the other and the unauthorized actuation of the lock-bolt is ef- C fectively safeguarded.

The preferred embodiment of the present invention consists in the features hereinafter particularly described and then sought to be clearly defined by the appended claims, reference being had to the accompanying drawing forming a part hereof and in which Figure 1 is a side view of so much of a lock-bolt as is necessary to show the present invention applied;

Figure 2 is an end view of Figure 1, with the lock-bolt and control-means in vertical section;

Figure 3 is a horizontal section on line 33 of Figure 1;

Figure 4 is a front view of a portion of the door to be locked and its frameshowing in front elevation another form of the padlock hasp that may be employed;

Figure 5 is a section on line 5-5 of Figure 4. Y v

In the drawing the numeral 1 designates a casing secured to a door 2 and which may contain in its upper portion 3 a recording mechanism, and below, in the lock-casing i, a lock-blot 5 operated by a key applied at 6 or by a key applied at 7 to turn the pinspindle S to throw the lock-bolt into its keeper 9 attached to the door-frame 10 or r to retract the bolt, which parts are of well known construction, for instance such as typified in the patent hereinbefore mentioned, and further illustration not necessary for a full understanding of the present invention. While the recording lock of the character mentioned affords practically absolute protection against unauthorized or fraudulent manipulation of the lock-bolt because of the record made by manipulation of the lock yet for the purpose of affording additional security I provide a lock-bolt control which must be actuated before the lock-bolt is free for movement and this control-means requiring for its operation a key different from that for actuation of the lockbolt it is neces sary that both keys be employed before the lock-bolt can be actuated and the keys being in the possession or custody of different persons the concurrence of both custodians is necessary before the door can be unlocked and opened. The control-means under the present invention comprises a stop or locking dog thrown into the path of travel of the lock-bolt after the latter has been thrown into locking position so that the lock-bolt cannot be retracted until the locking dog is moved out of its path of travel, said dog being held in its dogging position by externally positioned means under the control of the custodian of the key that locks said externally actuating means.

The preferred embodiment ofv this feature of the invention comprises a slidable pin or dog 11 positioned as illustrated in Figs. 1 and 2 to be projected into the path of travel of the lock-bolt 5 after the latter is thrown into locking position in its keeper 9 so as to prevent retraction of the lockbolt until after the locking dog is moved out of itspath of travel. The locking dog is projected through an opening in the bottom wall of the lock-bolt case by a suitable cam, as 12,attached to a rotatable spindle 13 passing through the door 2, the cam preferably acting. on the dog through the medium of a pivoted finger. 14 which has a forked end 15 engaging the dog between shoulders 1'6 formed thereon so that when the cam has been turned to the position shown in full lines Figs. 1 and 2 it has raised the finger 1a to the position shown in full lines in the same figures and the dog projected to its locking position, and when turned to the position shown in the dotted lines in Fig. 1 the finger has moved to its dotted line position shown in the same figure, by gravity, or under the influence of a spring 17, and the locking dog brought to its dotted line indicated position, out of the path of the lock-bolt so that the bolt may be retracted. To the outer end of the rotatable spindle 13 is attached one end of a hasp 18 which may be made in two parts with one connected to the other by a hinge 19 the free end of the hasp formed with a slot 20 to receive the hasp staple 21 adapted to receive the hasp of any selected approved type of key padlock for securing the hasp in the position shown, which is horizontal, when the lock-bolt is in its locking position. hen the door lock-bolt is thrown to the locked position, in engagement with its keeper 9, the hasp, which at other times stands or swings in a vertical position as shown by dotted lines in Fig. 2, is lifted to a horizontal, as shown in dotted lines in Fig. 1, and full lines in Fig. 3, which movement brings cam 12 from its dotted line position shown in Fig. 1 to its position shown in full lines, same figure, thereby raising the pivoted finger 14 and lifting the locking dog 11 into position at the rear of lock-bolt 5 in its path of travel, in which position the dog is held by engagement of the free end of the hasp with the staple in which position it is locked by a padlock, which may be the permutation type, whose pivoted hasp will engage the staple 21 in locking position, and thus the lock-bolt cannot be retracted or thrown into unlocked position until the locking dog 11 is moved out of its path by unlocking and removing the padlock which locks the hasp 18 to its staple 21. When the padlock is removed and the hinged part of hasp 18 swung from the staple 21, the hasp 18 will drop or swing to its vertical position so as to rotate spindle 13 and move cam 12 a quarter turn into the position indicated by dotted lines in Fig. 1, whereupon the slidable dog 11 will drop so as to move out of the path of movement of lock-bolt 5 and leave the latter tree to be retracted into unlocking position, the movement of dog 11 being by gravity, or positively effected by downward swing of finger 1 1 which may be aided by the spring 17. When the dog 11 is moved to unlocking position and the 1ock-bolt retracted, the dog will lie below the lock-bolt and it cannot be moved to projected locking position until the lock-bolt has been thrown into locking position beyond the range of projection of the slidable dog. It follows from the foregoing that the lock-bolt control. that is the slid'able dog, cannot be actuated until after the lock-bolt has been thrown into locking position, and that when the dog has been thrown into locking or dogging position the lock-bolt cannot be retracted until the lockbolt control, that is the dog, is moved from its locking position, and thus the retraction of the lock-bolt is dependent upon withdrawal oi the locking dog and the projection of the dog into locking position is dependent on the lock-bolt being thrown into locking position. Thus while the door is locked by a single lock-bolt its actuation is dependent on the concurrence of two persons or two independent key custodians, one be ing the custodian of the lock-bolt key and the other the custodian of the lock-bolt control, or padlock, key. This contributes to additional security, and safety against fraudulent or unauthorized locking and unlocking of the door. It also insures greater assurance that the door has been properly locked and placed under the protection of the lock-bolt control because so long as the hasp of the lock-bolt control in vertical position it indicates that the slidable dog is not in locking position and hence the lock bolt not guarded against retraction which is intended shall be the case so that itcan only be unlocked or retracted by first releasing the locking dog. Accordingly the custodian of the padlock key makes sure that the hasp 18 is brought into engagement with the staple 21 and the padlock placed and locked which gives assurance that the lockbolt has been thrown to locking position and cannot be retracted without knowledge on the part of the custodian of the key of the lock-bolt control do". This construction avoids the use of two lock-bolts to lock the door as in the present case only one bolt is used and is suilicient, and is safe guarded by the lock-bolt control under the control of an independent key.

The hasp 18 may be fixedly attached at one end to the rotatable spindle 13, or it may be detachably secured thereto as illustrated in Figures 4L- and 5. For instance, one end. oi the hasp may be formed with a curved lip 23 fitting in a correspondingly shaped socket 24 having an open-side 25 and formed as a head to the spindle l3, and having side cheeks 26 as illustrated in Figures 1 and 5 so that by placing the hasp at the proper angle to the open mouth of the socket the curved lip 23 will enter the socket and then turning the hasp so that it will extend from the socket in substantially the position shown in the drawing it cannot be withdrawn from the socket, and the cheeks 26 will prevent it from moving edgewise out of the socket. With the hasp coupled to the spindle as described when the hasp is placed in locking position it will remain securely attached to the spindle and cannot be removed therefrom. lVhen however the hasp is in its unlocked and pendent or hanging position it can be detached from the spindle by turning it to the angle that will permit its curved lip to be moved out of the socket. so that when the lock-bolt is in its retracted position the hasp may be detached from the spindle if desired, and when the door to be locked the hasp may be replaced in its coupled relation to the spindle for the lockbolt control to function as previously described.

For the purpose of limiting the throw of the cam 12, stop pins 27 and 28 may be positioned as illustrated in Figure 1 so that when the cam is in the full line position shown in Figure 1 it will be stopped by the pin 27, and when in the dotted line position shown in the same figure it will strike and be stopped by the pin 28, and thus an overthrow of the cam in either direction will be prevented. a

It is preferred to place the cam 12, finger 1.4 and slidable dog 11 within a case or shell 29 attached to the door below the lock-bolt casing 4 by bolts-30, or otherwise. The shell 29 is provided with a closure'face-plate 81 formed with a lip 32 to fit over and interlock with an upturned flange 33 formed on the shell and having at its upper edge a rearwardly extending plate or member 34 of any suitable width designed to lie between l the top of shell 29 and bottom of lock-bolt casing 4 and at the rear formed with an upturned flange 35 which will fit in a recess 36 at the back of the lock-bolt casing as indicated in Figure 2 of the drawing. Under the construction described access cannot be had to the interior of the shell to tamper with the lock-bolt control means because when the shell 29 is attached to the door and the lock-bolt case then installed the face-plate of the shell 29 cannot be removed without first removing the lock-bolt casing and thus fraudulent tampering with the parts is guarded against.

I have given a conventional illustration of a pad-lock 38 and pad-lock staple 21 but any appropriate well known type of pad-lock and staple with which it interlot=ks may be employed, nor is it necessary to illustrate details of the pad-lock as many different constructions are on the market, and the custodian under whose control is placed the lock-bolt control means may select the type of pad-lock and actuating key that best serves his purpose and with the view of preventing fraudulent manipulation of the parts so that the additional security sought is obtained.

The invention is shown as applied to be used with a well known type of recording door lock but the recording means does not constitute the present invention and therefore need not be illustrated nor described in detail; and the invention in its broadest scope is capable of use with a door lockbolt without recording means being associated with it.

IVhile I have illustrated and described with particularity the preferred construction and details of various parts it is to be understood that changes may be made therein and essential features of the invention be retained within the scope of the invention as sought to be defined by the appended claims.
