LATCH FOR LOCKERS Filed March 6, 1928 3 Sheets--Sheel Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE WILLIAM ISLER, OF CANTON, OHIO, ASSIGNOR TO THE BERGER MAN'UFAGTURING COMPANY, OF CANTON, OHIO, A CORPORATION OF OHTO LATCH FOR LOCKERS Application filed March 6, 1928.

This invention has for its object the provision of a latching mechanism for a locker or other enclosure, which will be simple in operation, sturdy in construction, permit of assembly, and present withal a neat and attractive appearance.

Another object of the invention is to provide a locker door having a tubular formation at the edge there-of, which formation 1o functions not only to reinforce the locker door, but at the same time serves as a bearing or supporting surface for slidably supporting a latching bar, and also serves to conceal the connection between the latching bar and the door handle which is adapted to be directly connected thereto.

In copending application of Joseph Sturm and lVilliam L. Caldwell, Serial No. 115,538, there is described a latching mechanism for a locker in which a latching bar is enclosed in a tubular housing or reinforcement at the edge of the door, the bar being positively forced into latching position by means of an especially designed hook or keeper which enters the housing and engages slots in the latching bar. In assembling the aforesaid latching mechanism, it is necessary to insert the latching bar into one end of the housing an d to push the bar up into the housing to a position in which it may be engaged by the tenons of an especially designed handle.

In accordance with the present invention, the positioning or assembling of the latching bar and handle is considerably facilitated by virtue of the fact that the latching bar is placed on the exterior of the tubular housing or reinforcement in a natural and simple manner, the bar being designed to be positively moved into latching position in the same manner as the latching bar described in the aforesaid application of Sturm and Caldwell.

These and other objects of 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. l is a front elevation of a locker in which is embodied the novel features of the present invention;

Fig. l1 is a cross-section through a `modified form of the housing and latching bar.

Referring more particularly to the drawings, the locker comprises a sheet-metal body l, and a door Q hinged thereon. The door 2 is formed at one of its side edges with a tubular reinforcement or housing 3, closed at the top by a flange 4, and open at the bott-om to facilitate removal of the mandrel used in forming the housing.

Disposed at vertically spaced intervals, preferably near the top, bottom, and middle of the housing 3, are slots 5 which serve to receive keepers 6 mounted on the locker body l, when the door 2 is closed. The keepers 6 are formed with an upwardly sloping edge 7, a downwardly sloping edge 8 approximately twice as long as the upwardly sloping edge, and a seat 9. Keyhole slots 10 enlarged at one end as at 1l are formed in the rear face of the housing 3, one of these slots being' positioned above the uppermost slot 5, and the other a short distance below the lowerniost slot 5.

The front 'face of the tubular housing` has formed therein, slot-s 12 which serve to re* ceive tenons 13 of a handle lll.

The lat/chingt bar 15, preferably made in the form of a channel for strength, has secured thereto near each end, a rivet 16 having' a shoulder 17 and an enlarged head 18. Secured at or near Vthe middle portion or" the web oil" the bar, as by spot welding, are clips 19 having` legs 2O and 21, provided with apertures 22, the apertures in legs 21 being` threaded. rEhe latchingr bar has termed therein at vertically spaced intervals, slots 23 terminating in upper enges 24; and lower edges 25, which are spaced to coincide with the slots 5, and which serve a purpose to be presently described.

The latching bar 15 and handle lll are assembled on the lune-.sing` in the :followingl manner:

The web of the latening` bar is placed adjacent the rear iface of the housing;` 3 in such a manner that the enlarged heads 18 of the rivets 16 pass through the enlarged ends 11 of the keyhole slotsv 10. Zhe bar is then moved upwardly until the legs 2O and 21 of the clips 19 are opposite the slots 12 in the front face of the housing. rllhe upward movement o'l the bar causes the shoulders 17 Ot the rivets 16 to ride up into the keyhole slots 10, and the enlarged heads 18 01' the rivets prevent the bar from being,l subsequently pulled away from the housing. The handle 14 is then placed on the door in such a manner that the tenons 19 enter the slots 12 in the front tace of the housing' 3 and lie alongside the legs 20 and 21 olf the clips 19, as clearly shown in` Figs. 2 and 9. Adjacent the slots 12, a portion ot the rear and inwardly directed lateral wall of the hcusinoj 3, and a Correspending` portion of one orf the flanges oi the latchingv bar 15 are notched out to facilitate the positioning` of the latch bar, and to permit the insertion or screws 26 havin@ threaded ends 27 Ytor the auriose of securing' the handle to the latching bar.

lt will be apparent from a consideration of 2 and l, that when the door is closed, the upper ed 24 ot the slots 23 .in the latching bar will ride up over the upwardly sloping edges 7 of the keepers 6, until the uppermost point olf these edges is reached. lower edges 25 olf the slots will then begin to contact with the downwardly sloping` edges 8 ot the keepers, and the edges 2d of the slots will he positively forced to move down into the seats 9. ln this manner, the locker door is effectively shut or latched, regardless el how great a torce is used to effect closing.

ln Fig'. 11, a modified torni of the housing and latchingr bar are shown. The housing 3 has vertically extending,` grooves 28 in the lateral walls thereeili, and the latching` bar 15 has inwardly directed flanges 29 which lit The I into these grooves. This forni of the invention does away with the necessity of providing` a bayonet connection of the latchingr bar to the housing, as shown in Figs. 6, 7 and 8.
