Loon-f Application filed January 14,1928. Serial no. 246,790.

This invention relates to that class of locks where in addition to a key-operated look a secondary means of operating the lock is provided.

It is a characteristic of locks in general that they are placed inside the door or other I member desired to be locked-a necessary precaution to prevent the removal of the look. It is sometimes customary to add to the ordinary look a padlock with hasp and staple and these are from their nature only applicable to the outside. A padlock gives a rugged and cheap additional protection and is a visible sign that the door is secured. The present invention comprises a combination with an ordinary lock on the inside with a hasp on the outside, the latter having means connected with itwhereby it may be made to throw the bolt of the inside look to the locked position when the hasp is placed on the staple, the construction being such that the removal of the hasp from the staple will not result in the unlocking of the bolt.

The invention further comprises a combination with such inside look and outside hasp, of a key operated member extending from the inside lock to the outside and so placed that when the hasp is in place on its staple the said key-operated member is covered by the hasp so that a key cannot be applied thereto.

, The invention has particular value when applied to a safety time recording'lock as the placing of the hasp on the staple resultin as it does in the throwing of the bolt, has the effect of making a record of closing. An opening record, however cannot be made until the bolt is thrown back by the key after the hasp has been removed from the staple and returned to its normally open position.

tion will more clearly be explained by reference to the accompanying drawings, which represent a preferred form that my invention may take:

. Figure 1 is a front elevation of the outside of a door and door jainb,-showing a padlock applied thereto. Q

Figure 2 is a horizontal section through the door and door jamb, an inside look and an outside padlock, on line of Figure 4.

to be locked together.

Further particular features of the inven-' Figure 3 is a vertical section on line 3'3 .ofFigureQf i f Figure 4 is a similar view on the line 4-4 of Figure 2, showing'the bolt thrown into the locked position. i 1 Referring to the drawings, adoor is shown at 1, and a door 'jamb at'2. These may be taken as an example of two members that are On one side of the door (theinside) a lock case 3 is secured to the door and has a bolt 4: slidably mounted therein which, when thrown, engages with a keeper 5 on the j amb. The bolt may be thrown by a key-operated member 6 which; is provided with a bolt-throwing arm 7 adapted to engage a cross piece 8 on a tumbler 9 and also to engage in a slotted portion 10 on the bolt in amanner' well understood in the art. At 11 is shown a time recording apparatus which has a member 12 operated by lugs 13 on the bolt to indicate on a rotating record sheet l'ttlle times when the door is locked or 5 unlocked. On the outside of the door is shown a hasp 15, hinged at 16 to a rotatable shaft 17 that passes through the door and has onits inneren'd an arm 1-8 which isadapted to make engagementwith an arm 19 and thus to rotate a bolt-throwing arm 22 pivoted on a stud concentric with key-operated member 6, the

engagementbeing such that when the haspiis '80 I put over afstaple 20 on thejamb, the member 18 impinging against the member 19 and rotating the arm 22 will throw the bolt into the locked position the same as if it had been operated by a key. When, however, the hasp is moved from the staple and lowered into a vertical position, as shown in dotted lines in Figure 3, the key-operated member will not be retracted so that the bolt will stay locked. The relation of the key-operatedmember to the hinge pin 17 is such that the hasp, when placed on the staple, will lie in front of the key-operated member covering the key-hole therein so as to prevent the operation of the inner look by the key until the hasp is re- 9 moved. ,It is evident, therefore, that as long as the hasp is on the staple the door is locked not only by the padlock shown at 21 but that man see that the door is padlocked, he will know that the time recording mechanism is also performing its function of recording the time as corresponding to a locked position of the door.

I claim 1. In combination, a bolt, means for throwing the bolt in either direction, means independent of said first mentioned means for throwing the bolt in one direction only, an auxiliary locking device, and a key operated member, one of said bolt throwing means being responsive to said key operated member and the other bolt throwing means being responsive to operation of said auxiliary locking device.

2. The combination set forth in claim 1, in which the second bolt throwing means is operative only to project the bolt.

3. The combination set forth in claim 1, in which the second bolt throwing means is operative only to project the bolt and is responsive to the locking operation of the auxiliary locking device.

4. In combination, a lock having a key operated member, an auxiliary locking device having a member which masks the key operated member when the auxiliary locking device is in looking position, and means for locking the auxiliary locking device.

5. In combination, a bolt, means including a key operated member for throwing the bolt, auxiliary means including a hasp for throwing the bolt, and means for locking the hasp, said hasp masking the key operated member when the hasp is in locking position.

6. In combination with a door and jamb, a bolt for lockingly engaging the door and jamb, an auxiliary device for lockingly engaging the door and jamb, means for throwing the bolt, and key-operated means for actuating said bolt-throwing means, said boltthrowing means being also responsive to operation of the auxiliary locking device independently of said key-operated means.
