Worthley, Minneapolis, Minn.- Application my 3,1943, Serial No. 4855472 My invention belongs to the cabinet art and pertains to an improved fastening device or apparatus for hinged cabinet doors. v

While the invention is adapted for use in connection with cabinets of many diiferent designs and for many different purposes, it was primarily designed for use in connection with cabinets for portable inotor generator sets, and, when so used, serves to maintain 'a constant closing pressure on the hinged cabinet door so long as the door is closed, thereby preventing accidental opening of the door, even if it be not positively locked closed,

3 claims. (01.292-228) tom, and side panels 8. 'I'he-frontof the cabinet is primarily open, but is provided with a hinged door 1. .All edges of the cabinet are shown as covered by cross-sectionally rounded reinforcing strips I. The door -I is shown as being in the nature of a wooden panel that is received in the door opening and which is provided at its edges with metal reinforcing strips 9 that project beyond the edges of the door panel and, overlap the outer edge portions of the door opening when the door is closed. This door 1 is hinged to the cabinet at its bottom edge portion by means of suitable .hinges N. The bottom of the cabinet is provided adjacent its opposite side portions with forwardly and rearwardly extending skidways II, which are adapted to slidably engage runners or skids ll of a platform It. In practice, a motor g'enerator' set such as indicated by dotted lines in Fig.

according to thepresent illustration, the biasing of the flange or wing is provided through the medium of a suitable spring or springs, and novel means is provided for holding the flange or wing in an outwardly-extended inoperative position.

As a still further feature of the invention, I prefer'ably provide the cabinet doorwith' one or more lock-receiving anchoring devices and provide the I flange or wing with a notch or notches to receive such anchoring device or devices. numerous other objects, advantages, and impor-' tant features of, the invention will'be made apparent from the'following specification, claims, and appended drawings.

- In the accompanying drawings, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a perspective view, with the'door'closed,

of a cabinet involving the invention;

Fig. 2 is aperspective view similar to Fig. 1 and showing the cabinet door and fastening flange or wing in their open positions:

Fig. 3 is a greatly enlarged fragmentary sectional view taken on the line 3'"3 of Fig. 2: and

2 will be mounted fast on the platform It and the platform and motor generator set will be slid as a unit into the cabinet for storage or transportation purposes, and will be slid out onto the opened-cover 1 during operating periods of the motor generator unit. Preferably, a drawer It for tools and accessories is slidably mounted in the upper portion of the casing on suitable rails i5 and is provided with 9. depending handle It for withdrawing the same slidably through the The above and opened front of the casing.

The hinged "wing or flange of the preferred embodiment of the invention illustrated, indicated by IT, is somewhat wider than the door opening in the cabinet and is pivotally connected to an anchoring flange it on an axis parallel to but spaced slightly above the upper edge of the door opening at H. In fact, the flanges or wings I! and I8 together form a long hinge having a free flange or wing I I and an anchored flange IS. The anchoring flange I8 is rounded to conform to the rounded upper front cornerof the cabinet and is anchored thereto by screws or the like 20. As a "means for yieldingly biasing the flange or wing i1 to'move to its closed or door opening overlapping position, a pair of coil torsion springs 2i are disposed overthe pivot pin of the hinge and have their opposite ends overlapping opposite flanges Fig. 4 is a fragmentary detail sectional view taken'on the line 4-4 of Fig. 3.

The cabinet illustrated is, as previously indicated, designed to house portable motor generator sets such as are used for field lighting and power purposes, and such amotor generator set is indi-' cated by dotted lines-in Fig. 2. Theparticular cabinet illustrated involves a rectangular wooden framework I, cut out to receive wooden'top, botor wings I I and It. To facilitate raising or opening of the wing l1 against the action of the springs 2|, I preferably equip the wings I"! with a suitable handle 22. v

While the spring-pressed flange orwing i! of the invention will exert sufficient resilient closing pressure against the upper edge portion of the door I to prevent accidental opening thereof, it is often desirable to lock the cabinet closed to protect the motor generator set or the like against tampering or theft. and for this, purpose I preferably provide the door I with apertured staplelike fastening devices 23, and provide receiving apertures 24 therefor in the flange [1. When the flange I! is closed over the fastening devices 23 as shown in Fig. '1, suitable padlocks maybe inserted through the apertured fastening devices 23 just as in the case of a conventional lock hasp.

As a means for holding the flange or wing I! in its raised inoperative position against the action of the springs 2|, I provide a mechanism comprising a headed plunger 25, a coil compresably in the pressed metal channel 27, which' latter is anchored to the top panel of the cabinet by anchoring screws 29 and has a closed inner end 38. The coil spring 26 is interposed between the closed inner end 30 of the channel 21 and the head 25a of the plunger, and has sufficient force and is of suflicient length to push the plunger outwardly to the position thereof shown by dotted lines in Fig. 3, when the flange i1 is raised to its open position. Now, when it is desired to retain the flange H in its. raised inoperative position without exertion of hand pressure, the operator merely pulls on the partially projected plunger 25 and slides the same out to its full line position of Fig. 3, wherein it will support the flange l'l against the action of the springs 2!. Usually the plunger 25 will be. left in this fully extended full line position so long as the door i is open. However, when the door is closed and it is desired to render the flange il operative thereon, the operator merely lifts upward slightly on the flange H to release the plunger of its pressure and then pushes the plunger back to its partiallyretracted dotted line position of Fig. 3, after which the closing pressure of the spring-pressed flange l'l will complete the retraction of the plunger 25 against the action or it spring 26 by cam action.

What I claim is:

1. In a cabinet having a door opening and an outwardly hinged door for said opening. a winglike flange pivoted to the cabinet adjacent the on an axis parallel to the axis of the door hinge, yielding means for biasing the wing-like flange to move over-a portion of the door opening and against the outside of the closed door to hold 8 against accidental opening movements and-rattling vibrations; and a plunger working slidably through the cabinet between an edge of the door a I opening and the pivot point of said wing flange, said plunger being free to slide longitudinally 10 from a retracted osition substantially flush with the outer wall of the cabinet to an extended position wherein it will support the wing flange in an inoperative position against the closing pressure exerted by its cooperating biasing means, and

5 yielding means tending to project said plunger.

2. Ina cabinet having a door opening, an outwardly opening door hinged thereto adjacent one edge of the door opening, a wing flange hinged to the cabinet adjacent an outer edge of the door opening opposite the hinge axis of the door and on an axis parallel to the hinge axis of the door and adjacent edge of the door opening, said wing flange extending substantially the length of' the adjacent edge of the door opening and being of sufficient width to overlap the adjacent edge l of the dooropening and edge portion of the door when the door is closed, yielding means biasing the wing flange to move into engagement with the outer face of the door and hold the same against accidental opening and vibratory movements and a plunger working slidably throughthe cabinet toward an edge of the door opening and the axis of the wing flange, said plunger being free to slide longitudinally from a retracted 5 position wherein its outer end is substantially flush with the outside of the cabinet to an extended position wherein it will underlie and support the wing flange in an inoperative open position against closingipressure exerted by its coop- 40 erating biasing means.

from which it is capable of being further retracted by cam action of the wing flange thereon under the action of its biasing means.
