PAUL VIGNOS, OF CANTON, OEO, ASSEGNOR, BY MESNE ASSIGNMENTS, 'IO REUBLIC STEEL CORPORATION, OF YOUNG-STOVJN, OEIO, A CORPORATION' OF NEV JERSEY LOCKING MECHANISM Application` led October 18, 1928.
This invention has for its object the provision of a locking mechanism for a locker or other closure, which will be simple in operation, of sturdy construction, permit of easy assembly, and present withal a neat appearance.
Lockers, of the type commonly used in schools, gymnasiums, etc., as urnishedby locker manufacturers, are usually7 equipped with individual cabinet locks, which are so made, that all of the locks in each group of six lockers, may be opened by means ot a master key, the master key being retained by the building superintendent or other custodian, to enable the latter to inspect the contents of the lockers when he so desires, As a matter of expedience, each locker is also equipped by the manufacturer with a padlock attachment, in order that the locker may be furnished with either a padlock or a cabinet lock, at the option of the purchaser. e
Assuming that a school building is equipped with 1500 lockers, this being the average number of lockers in a typical high school building, it would be necessary, where the lockers are equipped with cabinet locks only, for the superintendent to carry. or have available for ready use, 250 master keys for the cabinet locks.
If the lockers'were supplied with padlocks only, the superintendent would be obliged to carry 1500 keys. or one key for each padlock.
Too often, students, having lost their padlock keys, purchase and install other padlocks i on the lockers, and neglect to furnish the superintendent with duplicates of such new padlock keys. The dilliculties which arise, when the superintendent wishes to inspect the contents of a locker thus furnished with anew padlock, are obvious.
Even when cabinet locks are installed on each locker, students often take advantage of the padlock attachment on the locker to lock their own locker by means of a padlock. As a result, when the superintendent desires to inspect the locker contents, he is Jforced to lose much valuable time in opening lockers which are thus doubly locked, and particularlv if the student has failed to supply him with a duplicate key for such padlock.
Serial No. 313,253.
In the highly improbable eventfthat all of the students have supplied the superintendent with duplicates ot the padlock keys, the difculties would still be great, as he would be forced to carry, or have available for ready use, a key for each padlock, or 1500 keys, in addition to the 250 master keys for the cabinet locks. The mere possession and use of so' great a number of keys inevitably results in confusion, as will be readily apparent to anyone who has had occasion to carry many keys.
lt is a primary object of the present invention to provide a locking mechanism for a locker or other closure, which mechanism includes a cabinet lock and a padlock, either of which, when operated singly, will serve to unlock the locker.
Another object of the invention is to pro,- vide a locking mechanism for a locker or other closure, which includes a cabinet lock and a padlock, the padlock being capable of being opened by means of a key which is retained solely by each student, and the cabinet lock being capable ot being opened by means of one master key which opens all of the cabinet locks in the school building, and which is retained solely by the superintendent.
Other objects ot the invention will become more readily apparent in the course of the following description of one embodiment of the invention, taken in connection with the accompanying drawings wherein:
Fig. 1 is a front elevation of a locker in which is employed the novel features of the present invention;
Fig. 2 is an enlarged fragmentary crosssection through the locker door, taken on the line 2 2 of Fig. 1, and showing the various parts of the locking mechanism, the cabinet lock being omitted for clearness of illustration; Y
Fig. 3 is an enlarged fragmentary crosssection through the locker, taken on the line 3-8 of Figs. 1 and l;
Fig. l is an enlarged fragmentary front elevation of the locker, showing all the parts of the locking mechanism in relative position;
Fig. 5 is a fragmentary cross-section through the locker door, taken on the line -5 or Figs. 1 and 4, and showing the latching mechanism and method of securing the handle to the latching bar;
F ig. 6 is a perspective view of the handle;
Fig. 7 is a fragmentary view of the rear of the locker door-,showing the manner in which the latching bar housing is cut away to provide space for mounting the locking mechanism on the door;
Fig. 8 is a perspective view of the padlock clip;
Fig. 9 is aperspective view of the cabinetlock plate, and
Fig. 10 is a view of the shoulder rivet en-- ployed in securing the padlock clip to the cabinet-lock plate.
Referring more particularly7 to the drawings wherein like reference characters designate like parts, the locker includes a sheetmetal door frame 1, and a door 2 hinged thereon. The door 2 is formed at one of its side edges with a tubular reinforcement 3, which also serves as a housing for a latching bar 4. The latching bar 4 is forced into latching position by means of keepers 5,
which are mounted at vertically spaced points on the frame 1. The construction and operation of the latching mechanism is fully described in the patent to Sturm and Caldwell, No. 1,671,328.
The door 2 is provided with spaced slots 6, and the latching bar 4 is provided with spaced slots 7, the slots 6 and 7 being in registration with each other when it is desired to attach a handle 8 to the latching bar. ln attaching the handle 8 to the latching bar 4. the tenons 9 of the handle are inserted through the slots 6 and 7, the upper tenen forcing the flat spring 10, which is secured at its lower end to the latching bar, Vback to the position indicated in dotted lines in Fig. 5. rlhe latching bar is then permitted to move relatively to the handle, and the spring assumes the position shown in solid lines in f Fig. 5, and thus prevents accidental detachment of the handle from the latching bar, as well as relative movement between the handle and the latching bar. v
rllhe handle 8 is VfurtherY provided at its lower end, with a U-shaped portion 11, each leg of which is provided with a centrally disposed hole 12, these holes being in registration with each other.
The tubular reinforcement 3 is cut away, as at 18 (see Fig. 7), and a slot 14 is provided in the door adjacent the reinforcement at this point, and extending in line with the U-shaped portion 11'of the handle 8, this slot serving` a purpose to be presently described. A hole v15 is also provided in the door for receiving the barrel 16 of a cabinet-lock 17. provided with the usual bolt 18..
A cabinet-lock plate 19, provided with a centrally disposed hole 20, is formed with a flange 21 havinga slot 22 and holes 23 therein.
A padlock clip 24 is formed with a flat rectangular portion 25 having slots 26 and 27 therein, and an offset tongue 28 having a hole 29 therein.
The padlock clip 24 is slidably secured to the outer face of the flange 21 of the plate 19, as by means of shoulder rivets 30, the rivets passing through slots 27 and holes 23 of the padlock clip and plate respectively, and the slots 26 and 22 being in registration with each other.
rlhe locking mechanism is assembled on the door as follows:
Tongue 28 of the padlock clip 24 is inserted through the slot 14 in the door 2 and the plate 19 is secured as by welding to the rear face of the door in such position that the hole 20 therein registers with the hole 15 in the door, and the hole 29 of the tongue 28 registers with the holes 12 in the U-shaped portion 11 of the handle 8, as shown in Fig. 2. The cabinetlock 17 is then secured to the plate 19 as by means of bolts 31 and nuts 82. A padlock 83 provided. with a shackle 34 completes the lockmechanism.
rllhe operation of the locking mechanism is briefly as follows: Y
T he locker is latched andthe locking mechanism locked in the usual manner by causing the bolt 18 of the cabinet-lock 17 to pass through the slots 22 and 26 in the plate 19 and padlock clip 24 respectively, the key for the cabinet lock being retained by the superintendent. The locking is completed by passing the shackle 84 of the padlock 33 through the holes 12 and 29 of the handle 8 and padlock clip 24 respectively, and locking the padlock. rEhe key for the padlock is retained by the student.
Assuming open the locker, he unlocks and removes the padlock 83, and then lifts the handle 8 to cause the latching bar 4, which is secured thereto. to become disengaged from keepers 5.
Assuming that the superintendent wishes to make an inspection of the contents of the locker, he unlocks the cabinet-lock 17, thereby retract'ing the bolt 18 from the slots 22 and 26 of the plate 19 and padlock clip 24 respectively. the padlock shackle 34 to lift the padlock clip 24 a sullicient distance to cause the latching bar 4 to become disengaged from keepers 5.
rl`he slot 14 in door 2 is of such length that when the door is closed and the padlock clip 33 is in place, as shown in Figs. 2, 3 and 4, the lower edge of tongue 28 will lie upon the lower edge of slot 14, and the upper edge of the slot 14 is located a suliicient distance above the upper edge of tongue 28 to permit the padlock clip 24 to slide upwardly on rivets 30 a distance limited by the length of slots 27.
lt is apparent that either the superintendent or the student has access to the interior of the locker at all times and that it is unneclirst that the student desires to He then lifts-the handle 8, causing essary tor the superintendent to have a key for the padlock, or Jfor the student to have a kej.7 for the cabinet lock.
Furthermore, since the students are not supplied with keys tor the cabinet locks, identical cabinet locks, all opened by the same key, may be installed on all of the lockers in the building. It follows therefore that it is necessary for the superintendent to carry only one key, and the confusion attendant upon the use ot a. multiplicity of keys is entirely obviated.
t Will be readily understood that the locking mechanism shown and described is not intended to be limited tor use with the particular latching mechanism herein described, but may be used in connection with various other types of latches.
It Will also be understood that various changes may be made in the locking mechanism, per se, Without departing from the invention, the scope of which is intended to be limited only by the appended claims.
