Anothenobject of my inllpntionismtpprovide a support of the character indicated which will not only be automatically moved into projected lid supporting position when the lidis-swung from closed to openposition, but will alsohe automatically retracted into thecabinet when the lid is swung from open to closed position.

A further featureof my. invention resides in the fact that thesupporting arm isyieldingly projected into extended position and isv connected .with the lid only through a lostmotion connection, so that should the arm encounter awall or a piece of furniture or the like when being projected, its movement will be arrestedand no damage to the obstruction ortothe armor itsoperating mechanismwill result.

A further purposeof my invention is-to provide asupport of the character indicated which will be simple-in construction, consistingof few parts, and will, therefore, be economical to manufacture and which will be reliable and durable in use.

Other objects and inherent advantages of my invention will be readily appreciated as the same becomes better understood by reference to the following description when. considered in connection with the accompanying drawings.

It wilLbeapparent,frorn.Figs..5 and- 6tha mc-vementoi the. lidirom the .c1osedposi.- tion of Ei .6110. thecxtendedposition of Fig. 5 will move the link l9 longitudinally from the position of Fig. 6 to thatiotFig. 5, and conversely the return of the. lid from .extendednto closed positionwill slide the link along the guide slots 23 back into the position .indicated'in Fig. 6.

To the bottom face of-the cabinet top i2 there is secured by screws 24, which also secure. the hinge leaf= 5.to the cabinet top, aplate 25' having a downwardly struck portion 25 providing, as" shown in Figs. 5 'and6, an inclined surface against lwhich'an operating plate 21 is mounted for rotatable moyenientab'out apin tle'or fulcrum stud 23 This .plate'is provided with a'se'ctorshaped opening. 29 of substantial size having at one end a down turned flange 3i adapted to form a bearing surface of substantialarea againstwhich the dependingtoe 32 of-the link lQ 'abuts. The supporting arm 33, which may be of thank nel shaped constru'ctionas shown in Figs; 5 and 6, is fixed to the plate 21 by rivets 30, or otherwise, and carries at its ou ter end a' supporting padtr cushion 34 of felt, rubber or s af'fiiaterifh which is carried in ahdld'r 35fniou d upon ttfe arm near its' outer end? Thebdshion g niaterial prevents ms rmg of the contacting I firf'acebfthe lid, which beeomes" the iipper'expbsdstifate 6r the cabinet when the lid is in closed position, and also renders engagement of the lid with the support noiseless, should the lid be dropped before being fully opened.

A coiled tractile spring 36, connected at one end to a lug 31 struck downwardly from the plate 21 and at its other end to a lug 38 struck downwardly from the plate 25, induces a counter-clockwise rotation of the plate 21 (Figs. 3 and 4) thereby biasing the supporting aim into the projected position illustrated in Figs. 1, 2 and 3. The extent of rotation of the plate and supporting arm in this direction is limited by engagement of the bearing flange 3| with the toe 32 of the link l9, so that when the lid is in extended position, as shown in Fig. 5, the supporting arm assumes the operative projected position shown in Figs. 1, 2 and 3. If now the lid be swung upon its hinges to the closed position of Fig. 6, the link will be slid inwardly to the right, viewing Fig. 5, to the position shown in Figs. 6 and 4, thereby rotating plate 21 in a clockwise direction from the position of Fig. 3 to that of Fig. 4 to retract the supporting arm into the position of Fig. 4, which is also illustrated in dotted lines in Fig. 2.

From Figs. 5 and 6 it will be apparent that the inclined depression 26 of the plate 25, upon which the rotatable plate 21 is mounted, causes the rotatable plate to be disposed at an angle to the horizontal, or, in other words, to be upwardly inclined from its inner edge outwardly. The supporting arm 33, consequently, when projected from inoperative to operative position, carries the supporting pad upwardly as well as outwardly from the cabinet, thus disposing it substantially in the plane of the lower face of the cabinet top to receive and support the lid in alignment with said top. Upon reverse or retractive movement of the arm, the inclination of its carrying plate causes the pad 34 to move downwardly, so that it will pass beneath the top I2 and be disposed entirely or substantially within the confines of the cabinet.

It will be apparent from the foregoing that I have provided a lid support in which the supporting arm is normally concealed within the cabinet, but when the lid is swung from closed to open position, the arm is automatically projected from the cabinet and moved upwardly to provide a support for maintaining the lid in alignment with and forming an extension of the cabinet top. Upon return of the lid to closed position, the link pushes the rotatable plate upon which the supporting arm is mounted in the opposite direction against the action of spring 36, thereby returning the arm to the cabinet.

It will be observed that the arm is continually biased by the spring toward projected position. The extent of its movement in that direction at any time being limited by the position of the lid controlled link l9. If the link, however, were positively connected with the plate 21, the supporting arm would be positively projected by opening movement of the lid. In such event engagement of the positively actuated arm with a wall or a piece of furniture or the like would result in injury to the article or to the mechanism, or both, whereas, the spring induced projecting movement of the arm efiected by my invention enables the outward movement of the arm to cease upon encountering an obstacle, irrespective of the continued movement of the lid.

The structural details shown and described and the size, shape and proportion of the various parts are capable of considerable modification without exceeding the scope of my invention as defined in the following claims.

I claim:
