To all whom z't may. concern.'

Be it known that we, AXEL F. ERoKsoN and DANIEL W. SHEEK, citizens of the United States, residing at Aurora, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Latches and Locks, of which the following is a full, clear, and exact description.

This invention relates to latches or locks for doors and other structures. More parthis structure is designed for use clothing or wearing apparel, and is especially designed to hold the mechanism in position for re-latching when the door is open and to secure the re-latching thereof through the simple closing of the door.

The principal object of this invention is the provision of a latch and lock, the former whereof will be actuated to engage .the striker/or jamb-plate and be latched without having to raise the operating mechanism, and thereby insure the latching operation whether the door` is slammed or closed in an easymanner. Other objects of the invention consist in the provision of a latch for doors and the like that is simple in construction and which may be stamped entirely` of metal Aso that it is easy' to manufacture and simple in construction and can be sold for a reasonable price, or Will not add materially to the cost of the structure with which it is assembled. The design of this vstructure facilitates the locking thereof through the instrumentality of a cabinet lock or padlock or both where such double precaution may seem desirable. Also, by the provision of the specially designed striker or jamb-plate,

the door after being latched is prevented.

from being forced open by inserting a jimmy or similar tool between the edges of the doorway and the door, because the striker or jamb-plate coacts with the latch elements carried by the door in such manner that the door may not be pulled outwardly nor forced laterally or sidewise to escape the jamb-plate. The foregoing objects and others are accomplished by substantially the means hereinafter fully described, and as more particularly pointed out in the claims. Reference will now be had to the accompanying'drawings forming a part of this specification, in which- Figure l is a horizontal section of adjacent portions of a door and door-frame of a locker showing the improved construction in plan 1n operative position, the view belng taken on line 11, Fig. 2.

Fig. 2 is an elevation of the latching mechanism in the center of the structure, the viewr belng taken on line 2 2,- Fig. 1.

Fig. 31s a view similar to Fig. 2 showing the mechanism raised in unlatched position and about to engage the striker plate.

Fig. 4 is a vertical elevation lof the mechor jambanism looking at the same from the rear or back of the door.

Fig. 5 is a perspective of the latch supporting spring element.

In the drawings, similar reference characters are employed to designate the same parts throughout the divers views, and by reference to Fig. 1, the numeral 10 designates the upright angle-piece forming 'one' door opemng, and a portion of' edge of the the frame of the locker, which latter is con- 'I structed in this instance, of metal sheets supported upon a frame-work of ang1e strips, similar to that just referred to.

Mounted upon this angle strip 10` are strikers or jamb-plates 11, the one about midway the height ofthe opening ofthe door being alone illustrated in Figs. 1, 2 and 3. The outer portion of the plates are offset or bent obliquely inwardlyl to accommodatel the thickness of the door and some of the mechanism carried thereby, as shown in Fig. 1,

and provided with recesses or notches 12 for the reception of the latch clips.

The door, preferably, comprises a sheet of metal 13, the vertical edgeswhereof are folded or bent back upon themselves to provide rounded corners 14', and are folded flat against the rear face, as'shown at 15 in Fig.

1. A slight' distance from edge 14 the folded back portion is formed semi-circular to provide a reinforcing rib 16 on the back of the door, and the end edge 17 of this bent back; portion is then folded flat against plate 13,'all as shown in detail in Fig.' 1.

There. are, preferably, three strikers or jamb-plates 11; one midway the height of the door, as before mentioned, and one each adjacent the uppery and lower ends of the door, each of said strikers being adapted to be engaged by Aa latch clip 'of the special construction.y herein shown.- These latch clips, as seenin the drawings, are, preferably, of channel shape, the flange 18 WherellQ l as hereinafter described. The flange 21 op posite flange 18 is shorter than the same and is constructed somewhat hook-shape to engage the striker or jaInb-plate, and has its lower edge 22 inclined in the latch bolt or like structure. The folded back portion of the door plate is, preferably, horizontally slitted, and the metal between these slits is punched outwardly to provide a strap23 between which tongue is adapted to be slidably mounted. It will now be seen that by raising bar 19 the three latches may be disengaged from the the strikers or 4 jamb-plate 11 and the door opened. For convenience, slots 24 are made in the door frame, and lateral members 25 on the upper and lower portions of a handle 26 are passed through said slots and secured to bar 19, Handle 26 is placed in a loop, as shown, and by grasping handle 26 and raising the same the latches may be disengaged, and both the upper and lower horizontal members of handle 26 are provided with extensions 25% which are for the purpose of covering or obscuring slots 24 in door through which the handle extends when the mechanism is in its lower or latched position.

As previously stated,the principal object of this invention is to provide means for easily closing the door and insuring the latching of the same, and this is done by providing means for automatically engaging and supporting the latch clips with the bar and their associated elements in an elevated position when the door is opened, which means is adapted to release the clips and associated elements by engagement with the jamb-plate or other element. Thisconsists in providing a spring plate 27, the lower end whereof is mounted upon the rear of the door by means of a pocket formed by a strap 28, similar to strap 23, heretofore mentioned, and above this strap the spring plate 27 normally extends away from the rear surface of the door. The spring plate is deflected or bent slightly to a different plane,

at 29, for thepurpose of causing .it to engage the lower portion of flange 18; also to accommodate tongue 20 when the latter is in its lowered or latched position, as seen in Fig. 2, where the upper portion extends up into a slot m made in the corner of the lock clip between the members 18 and 21 thereof. Al lateral member 30 projects to one side adjacent the upper end of spring 27, and this member is also bent laterally so as to press against the adjacent edge or plate 18' in slot a2, as shown in Figs.y 1 and 2.

When bar 19 1s raised by moving handle 26 1 manner of av to the upper limit of its movement the offsetextension 30 of the spring will be positioned .slightly below the lower edge of member 18 and will snap undervthe same when the door is slightly opened, as shown in Fig. 3 of the drawings, in which position it will support the latch clip in a position above the horizontal plane o-f the j-amb-plate or striker 11.v The portion of the'spring above odset by the front face of the striker orv jambplate when the door has been nearly closed, and a very slight contact made between these parts will press the upper portion of the spring toward the door and release offset extension 30 from the under edge of member 18, thus permitting the llatch clips and bar "19 to gravitate with their associated elements and cause flange 21 of the clip to pass over the striker or jamb-plate and engage the o-pposite face thereof to latch the door.

When it is desired to employ a padlock for locking the door, we have provided a right angular projection 31 on the spring plate 27 that passes through a slot 32 in the door plate and 'is provided with an aperture 33 alining with a corresponding aperture 34 in the lower member of the handle when the latter is in lowermost position (Fig. 2). The bale of a suitable adlock 35 is adapted to be passed through tffese alining apertures 33 and 34 and locked, thus preventing the raising of handle 26 and the unlatching of the door.

There is, preferably, but one of these springs 27 employed in this structure, and this is positioned at the intermediate latch clip. It is desirable to sometimes employ a cabinet lock upon the interior of the door, and for this purpose we bolt such a lock 36 upon the door panel in the manner shown in Fig. 1, and provide a lateral extension 37 upon' the upper edge of the intermediate latch clip that extends obliquely from the inner edge of bar 19 forwardly toward lock 36 and is then provided with a forwardly bent end 39 that extends the same under the retractable bolt 38 of the'lock to maintain the mechanism in its lowermost or latched osition until bolt 38 is withdrawn through the operation of the lock in the `usual manner.
