In operation, the lock is set with the parts as shown in F 2 and al. Then in this posit-ion, the projection 5S on the lever 5G engages the notch 4:0 in the disk 87 and holds said disk against the action of spring 53 so that the cam all on said disk is in engage ment with the end of the block 27 and holds said block in the position shown in Fig. 5
to prevent the lock bolt el trom entering the slot Q5. t the same time, the detent 3l is held in its retracted position by the spring 32 and the lever 14 is in its uppermost position as shown in said Fig. so that the pin 16 engages the notch l2 in the locking bolt 41 to prevent said boltl from moving into a locking position. fit this time, the milk bottles have been inserted in the receptacle l and the door 2 closed, the disk 87 having been rotated by the key 2O to move it into the position stated, and inclined portion 45 of the cam elli having operated to move the block Q7 to retract the bolt et to allow the parts to assume the positions stated. At the same timel the door being closed` the pin on the arm 64: is in engagement with the notch 73 on the bracket 71 and is held in engagement with said notch by means ot' the spring 7G, the pin G9 on the other terminal otsaid arm 6l engaging the reduced portion Gl on the lever 56, and at this period ot the operation ot the device, the engagement of said pin 70 with the notch 73 operates as a latch to prevent accidental opening of the door Q. Atthis period in the operation of the device, it will be apparent that any one can open the door 2, and when said door is open for the removal of the empty milk bottles contained therein, the pin 70 will ride upwardly on the inclined port-ion 7% at the outer extremity of the notch 73 and by so doing, will oscillate the lever 5G so that its dowi'iwardly extending end 58 is released trom the notch it() in the disks 37 and said disk will be released to the operation of the spring 53 and be rotated on the pintle 4Q. lhen the disk 37 is rotated as stated, the inclined portion t6 ot the cam .4e by engaging the notch in the detent 3ft will more said detent outwardly of the casino` 24 against the resistance of the spring 32 and hold it in said outwardly extending position, as shown in Fig. 3. This movement of the disk 37 and cam 44 thereon will also bring the inclined portion 45 of said cam into position so that said inclined portion will be opposite the inclined surface on the block 2T and the cam 44 will be no longer in position to interfere with the retractile movement of the block 2T. After inserting the full milk bottles in the receptacle, the door 2 will be closed, and in closing said door the projected end of the detent 31 by engaging the beveled portion 23 of the upwardly extending projection 22 on the lever 14 will operate to move the end of said lever downwardly against the resistance of the spring 19 and by such downward movement of the lever, will release the pin 16 from engaging the notch 12 in the rearward eX- tension 10 of the locking bolt 4. W'hen said pin 16 is removed from engagement with the notch 12, it will be apparent that the locking' bolt 4 will be moved outwardly by the action of the spring 9 and the end of said locking bolt 4 entering the slot 25 of the casing 24 will hold the door in a locked position. Said locking bolt 4 by moving in the locked position as described, operates to move the block 27 into its rearmost position.
To open the door, when locked as just described, the key 50 is inserted in the slot 48 and into engagement with the end 47 of the pintle 42 and the disk 37 rotated by said key against the resistance of t-he spring vWhen the disk 37 is rotated as stated, the inclined portion 46 of the cam 44 is moved upwardly to permit the spring 82 to withdraw the projecting terminal of the detent 31 into the casing 24 and at the same time the inclined portion 45 of said cam engages the beveled portion 30 of the block 27 to move said block, and with it the locking bolt 4 against the resistance of the spring 9 until the locking bolt assumes the position shown in Fig. 5 when the pin 16 will be moved upwardly into engagement with the notch 12 and the parts will be in the position as first described.
