This support ispivotally mounted release of the latching means to project said for vertical swinging movement upon the door outwardly towards its open position. carriage plate 10 which, in turn, is mounted With the above and other objects in View, within the'body of the cabinet for vertical travelling movement between the upper and lower ends thereof. The carriage plate, to-

gether with the clothes rack support, moves by gravity to a normal position at the lower 5 end of the cabinet, and is raised or elevated to the upper end of the cabinet by means of a rope or other" flexible connection 11 with the carriage plate 10, said flexible element extending downwardly through the bottom wall of the cabinet adjacent one vertical edge thereof as shown in the drawing. When the carriage plate 10 is in its normal lowered position, the support 8, together with arms 9, may be raised in a perpendicular position in substantially parallel relation with the carriage plate 10 and with said-support and the arms 9 disposed within the open side of the cabinet body. Upon-then. closing the door 6, the various parts of the clothes dryer are completely concealed as well as housed and protected against injury or the collection of dust and dirt thereon. 7

'It is desirable, of course, in cabinets of this kind, designed for use in private apartments or dwellings, that the cabinet shall detract as little as possible from the appearance of the room, and also that there shall be a minimum of projection of cabinet parts from the face of the wall. To this end, therefore, I have devised an improved latch means for the cabinet door which altogether eliminates any projection whatsoever from the face of the door for the purpose of releasing the latch and moving the door to open position. In the illustrated embodiment of my invention, this door latch means may consist in the latch finger shown at 12, which is in the form of a rigid metal arm which is welded or otherwise permanently fixed to the inner face of the door plate near its lower end and adjacent to its free vertical edge. This latch finger or arm projects at right angles to the plane of the door plate and has a vertically extending edge 13 disposed in spaced par allel relation to the inner face of the door and the obliquely inclined edge 14 extending from the rear edgeof the latch finger to the upper end of its forward vertical edge 13.

The latch finger 12 is so located relative tothe rack support 8, that when the latter is raised toits vertical position within the open sideof the cabinet,upon closing the door the inclined edge 14 of the latch finger is brought into bearing engagement against the lower edge of the support 8 before the door reaches its fully closed position. Upon then applying the requisite pressure against the outer face of the door, this inclined edge 14 of the latch finger forces the support 8 and its carriage upwardly within the cabinet until'the lower edge of the support 8 rides over the upper terminal ofthe latch finger, whereupon said carriage and the support will drop by gravity to their normal positions,

and the. lower edgeofthe support 8 will be interposed between the vertical edge 13 of the latch finger 12 and the rear face of the door 6. Thus the door is securely latched and tightly held in its fully closed position. Since this latching means is wholly contained within the body of the cabinet, it is obvious that there is no possibility of the latch being accidentally released as might occur if the same were actuated by a movable part on the face of the door.

It will nevertheless be evident that when desired, the door can be very easily and quickly released for movement to its open position, merely by pulling downwardly upon the end of the flexible element 11 which extends through the bottom wall of the cabinet. The carriage plate 10 with the support 8 will thereby be lifted for a sufficient distance to I herein shown a sheet metal cup 16 having.

its open end, securely fixed in the support 8 and housing the coiled springl'? which surrounds a reduced part of the pin 15 projecting through an opening in the, closed end of the cup 16.

It will be evident from this description 1 that when the door 6 is moved to its closed position, the rear side of said door before the latter is, fully closed comes into bearing contact against the outer end of the pin 15, and forces the same into the cup 16, thereby compressing the spring 17. .Thus when the door is fully closed, the expansion pressure of this spring acting on pin 15, is transmittedto the door 6, tending to urge the lat.- ter towards an open position and thus hold the edge 13 of the latch finger 12 in bearing contact against the lower edge of support 8. Accordingly, when said support is raised to release the same from engagement with the latch finger, said spring pressed pin 15 will immediately act to move the door towards its open position, so that upon the release of the pulling strain on the flexible element 12 and the descent of thesupport 8 to its nor mal, position, the latch finger 12 will be out of the path of movement of the support. The door may then be manually swung to its full open position at one side of the cabinet body. v

' From the foregoing description considered in connection with the accompanying draw ing, theconstruction, manner of operation.

and several advantages of my present invention will be clearly and fully understood. Itwillbe seen that I have devised a very l/Vhile this pin might be mounted means, from the face of the cabinet door.

When thedoor is closed, the finger piece or hand grasp attached'to the flexible element 11 is positioned closely adjacent to the bottom wall of the cabinet so that it' will be quite inconspicuous. Although this use of the flexible operating element which is provided for raising and lowering the carriage plate 10 and racksupport within the cabinet for the purpose of releasing the door latch, will usually be found quite sufiicient, it is nevertheless just possible that this flexible element might break or become detached from connection with the carriage plate 10, so that in such event, if the cabinet door were closed, it could not be opened without serious damage thereto. Although this possibility is somewhat remote, I nevertheless herein suggest the provision of an emergency means whereby the carriage plate and the rack support may be lifted sufliciently to release the latching finger on the door. As shown, this emergency releasing means may conveniently consist in the provision of the pin 18 suitably fixed at its upper end to the lower end of the carriage plate 10 and projectingdownwardly through the opening 19 in the bottom wall of the cabinet body, when said carriage plate is in its normal lowered position. This pin also will be quite inconspicuous, and need only project through the opening 19 for a distancesuflicient to raise the lower edge of support 8 above the upper end of the latch finger 12 when an upward pressure is applied to the lower end of the pin. However, it is to be understood that this emergency latch releasing means is not essential, and may be eliminated if desired.

It will be apparent from the above description that the several elements comprised 111 my improved latch means for a cabinet door are of very simple mechanical form, and may be readily ap'plied'in the manufacture of a dryer cabinet, without materially increasing production cost. The device is also exceedingly durable, as well as highly efficient and serviceable for the purpose in view. Although I have herein shown and described one simple and practical embodiment of my improved cabinet door latch, it

is nevertheless to be understood that the essential features thereof might be incorporated in various other alternative, structural forms, and I therefore reserve the privilege of resorting to all such legitimate changes in the form, construction and relative arrange ment of the several elements as may be fairly embodied within the spirit and scope of the appended claims.

I claim:

1. In combinationwith a cabinet having Y a hinged door, and a member mounted within 1 said cabinet for vertlcal movement; a latch finger projecting from the rear face of said door for cooperatlve latching engagement with said member when the latter is in itslowermost position within the cabinet, means extending exteriorly of the cabinet for moving said member upwardly therein out of engagement withthe latch finger, and spring means on the vertically movahsle member placed under compression by the door when.
