8 Claims. (Cl. 292-64) This invention relates to latches designed parinto U-shaped form; having a .connecting web I ticularly for use with refrigerators and adapted at the innerV side with spaced apart parallel sides to be mounted and housed within va refrigerator 2 extending therefrom- Eachvof said sides at door; -It isof courseto bel understood that the its outer free `ed'geportion is turned at right an- 5 latch is adapted for use on other doors than regies, making attaching ilanges 3 which, as-shown frigerators andis not applicable only to refrigin.Fig. 1, -bear against a part ofthe' refrigerator erators.V y door A Vwhen the latch is vhoused therein, screws It is an object and purpose of the present i'npassing through the attaching an'ges for securvention to produce a practical, serviceable, and ing the latch permanently in place.

Said will securely engage withfthe keeper to hold the bars extend inwardly from the bolt in spaced door closed. However, through anyv suitable apart relation andat their inner end portions manually operable means for releasing said toghave'` longitudinal slots 8 cut therein' through to break and the latch bolt disengage from the" at the-knee or knuckle of the toggle structure to keeper for opening the door.

A Fig. 4 is a similar section showing the latch bolt coiled compression spring I5k has its end 'portions retracted, and passing over the member I3 and the projection Fig. 5 is a lsection substantially on the plane I4, the effect of the spring being to normally 5u of liney .fi-liv of Fig. 3, looking in the direction move the bolt to outer position. However, when 5u indicated. o a suitable force is applied against the bolt head Like reference characters refer to like parts 6 the bolt consisting of said head 6 and the bars in the different iigures of the drawings. 1, may be moved bodily inward for a distance In the construction of the latch, a supporting which is controlled by the length of the slots 8. 5 housing is provided, made from ilat metal pressed A pin I6 is located between the sides 2 of the 5 vthe latch bolt and the arms support and carried thereon in front of the pivot pin 9 of the knee or knuckle of the toggle when the bolt is in its operative latching position as shown in Figs. 1 and 3. Qn the pin I6 a toggle holding or stop member is pivotally mounted, formed from a single piece of dat metal with spaced apart sides I1 connected at their outer ends by an integral cross member I8. The sides I1 are provided with curved slots I9 as shown through which the ends of the pin 3 extend. The sides I1 are located against the outer sides of the bars 1 as shown in Fig. 5.
With the latch in its operative latching position, as shown in Figs. 1 and 3, the pin 9 is in the upper ends of the curved slots I9 which curve away from the pin toward the direction of the free edge of the door in which the latch is mounted so that the pin has a bearing against the lower sides of the upper end portions of the slots. A coiled torsion spring 20 surrounds the pin I6 and has one arm at an end thereof resting against the inner side of the connecting bar I8 and the other arm 22 against a lip 23 which is struck from an adjacent side 2 of the latch housing or support. The tendency of the spring is to rotate the stop or holding member consisting oi the parts I1 and I3 in a counterclockwise direction or to the position shown in Figs. l and 3. In such position the toggle lever is securely held against breaking at the knee or knuckle because of an impossibility of the pin 9 moving toward the iront of the door, being stopped against such movement by the parts of the sides I1 which extend under the pin 8 toward the slots I9.
The sides I1 of said holding member are provided with laterally extending arms 24 at their outerv end portions and to one side thereof, through which arms a pin 25 extends. A fork 23 has the two branches thereof'connected to the opposite ends of the pin 25 outside of the arms 2l. A pin 21 is connected to the fork-at its middle portion and extends outwardly and passes through the front side of the door A as shown in Figs. l and 2. A vertically positioned handle 28, having a central web 29, is secured to the door, the pin 21 extending into a recess in said web and being surrounded within said recessl by a compression spring 30. A manually operable push bar 3i is mounted on the'handle, the handle being vertically slotted for projection of the narrower portion of the handle through said slot. The inner part of the handle has laterally extending ribs 32 against which the spring 33 engages at one end to normally hold the push bar 3| in its outer position, the handle being stopped at its outer position by engagement of the ribs 32 against the bottom of the recess within the web 29 of the handle. Pushing inward on the operating push bar 3I compresses the spring 30 and moves the pin or rod 21 inwardly, thereby turning the toggle holding stop member in a clockwise direction. Such turning movement not only frees the pin 9 of the stop which has held it, but at the same time the curved outer sides of the slots I9 act as cams against said pin 9 to move it thereby not-only breaking the toggle consisting o I0 toward the posiaway from the web I, the'toggle, but moving tion shown in Fig. 4.
The means shown and described for releasing and breaking the toggle structure is one only of a great many that can be used; therefore the invention is not to be limited in any respect to the specic manually operable toggle releasing means shown and specifically described.
y tudinally inward and On the front door frame of the refrigerator B a suitable -keeper 33 of conventional design is secured, having a recess to receive the head 6 of the latch bolt in front of which is a cam for the rear cam side of the bolt to ride over in closing the door. The spring 20, with the door in open position, and the push bar 3| released, will move the parts of the latch to the position shown in Figs. 1 and 3. When the door is closed the cam inner or rear side of the bolt 6 rides over the cam portion of the keeper 33, moving the bolt longicompressing spring I5 until the bolt has passed beyond the cam on the keeper whereupon the bolt is projected Yinto the recess of the keeper by the spring I5.
As is common in refrigerator constructions, a cushioning compressible gasket 3|, usually of rubber, is secured at the rear side of a projecting lip or riser 35 at the free edges of the refrigerator door. This gasket is compressed when the door is closed and the latch has engaged with the keeper, and provides a very secure seal to the door, preventing escape of refrigerated air or the entrance of warmer air from the outside.
In releasing the latch from the door it is necessary merely to clasp the handle 28 and with the palm of the hand push inwardly on the push bar 3|. This moves the holding member for the toggle latch structure to release the pin 9 at the knee or knuckle of the toggle and move the same outwardly for a distance. As soon as the toggle is broken the force of the compressed gasket 34 acts to move the door outward and away from the side of the refrigerator to which it has been latched, and acts to turn the parts of the latch still farther in the direction toward which they were started by operation of the push bar 3|, or eventually to the position shown in Fig. 4 in which the latch bolt is free of the keeper and the door may be readily opened. Then, as soon as the push bar 3i is released, the door being open, the latch parts assume the position such as shown in Figs. 1 and 3. The door closing operation consists in swinging the door to closed position with the head 6 of the latch bolt riding on the cam 0f the keeper until it reaches the keeper recess and thereupon it is projected into said recess by the spring I5.
The structure described is relatively simple, economically manufactured, durable and sure in its service and operation.
