Patented July 11, 1933 UNITED STATES PATENT OFFICE- WILLIAM JOSEPH KASSICK, OF NEWARK, NEW JERSEY, ASSIGNOR TO GENERAL 3 ELECTRIC COMPANY, A CORPORATION OF NEW YORK- HINGE Application filed February 12, 1329. Serial at. 339,351.

My invention relates to hinges, more particularly to hinges for table leaves and the connection with tables provided for culinary service and the like. The ordinary extension table when used in such service'has proved unsatisfactory at times in that with the leaf in its lowered position matter swept from the table would lodge upon the upper edge of the leaf in such quantities'that it would be impossible either to raise the leaf to its extended position or to do so without severely straining the hinge fastening means provided for-the leaf.

In one of its aspects, mymvention contemplates the provision of means for fastening the table leaf so that it will be impossible for matter to collect on the upper edge of the leaf. Moreover, I arrange the fasteningfmeans so that the table leaf when lowered will be positioned so as to present a very pleasing appearance.

In carrying my invention into effect in'one form as applied to a table, I provide hinge means for the table leaf whereby when the leaf is in'its raised position, its upper surface will lie in the same plane with the top surface of the table and when it is in its lowered position, its normally upper surface will be flush with the edge of the table top. Moreover, I provide hinge means for the leaf whereby when the leaf is lowered, it will be forced into engagement with the under surface of the top.

For a more complete understanding of my invention, reference should be had to the ac companying drawing in which'Fig. l'is a perspective view of a dish washing machine provided with a table having an extension leaf hinged in accordance with my invention,

the leaf being illustrated in its raised posi tion; Fig. 2 is a vertical section of a portion of the table with the leaf in its raised position; Fig. 3 is a vertical section of a portion" of the table with the leaf in its lowered posi tion; and Fig. 4 illustrates the operation of the hinge fastening means as the leaf is being lowered.

Referring to the drawing, I have shown my invention in one form in connection with a dish washing machine provided with a suitable table which'awhen the machine isnot in use may be used-in place of the ordinary kit- 65 ohen table. As shown, the dish washing machine 10 is provided with a table comprising a top 11 having a reentrant lower surface 11a,

and a leafefxt'nsion 12 located at one edge of the top. it will be understood that the leaf 12 will occupy a substantially horizontal position when raised so that its upper surface will lie in a plane with the upper surface of the table. Obviously the other edges of the top may be provided with'like leaf extensions. Although the table is shown formed of a suitable metal, it will be obvious that it may be formed of any suitable material.

I provide suitable hinge fastening means for the leaf 12 so that when lowered its'nor- 7 mally upper surface will be flush with the adjacent table edge and the upper edge of the leaf will engage the under surface of the table top. It will be understood-that the leaf maybe provided with any desired number 7 of hinges spaced laterally along the secured edge of the leaf. Preferably in the table shown, the leaf 12 will be provided with two hinges; As shown, each of these hinges comprises a pair of mechanically interconnected links 13 and 14. The link 13 is .pivotally mounted by means of the pin 15 to the under surface of the table top while the link 14 is rigidly secured in any suitable manner to the under surface of the leaf. As shown a pin 16 serves to pivotally interconnect the outer ends of the links 13 and 14. The link 14 is provided with an abutment or lug 17 which cooperates with a companionate abutment 18 formed by the link 13 so that the two links form a substantially rigid armupon which the leaf may be swung about the pins However, in order that the leaf 12 may clear the adjacent edge of the table top while the leaf is being lowered, a suitable clearance, designated by the ordinal 20, is provided between the lug 17 and the abutment 18. As shown, Fig. 4, this clearance is proportioned to permit the leaf to swing about rotatably mounted.

the pin 16 through a suitable are before the lug 17 engages its companionate abutment 18. By reason of this construction, it will be apparent that the leaf in being lowered will be swung around the adjacent table edge to a position below the bottom surface of the top.

It will be observed, however, that with the construction thus far described the leaf when lowered would occupy. a position permitting considerable clearance between the top edge of the lowered leaf and the reentrant under surface of the table. I have provided, therefore, a fixed abutment 21 shown as a roller, this roller being arranged to engage the lower surface of the link 14 as the leaf is being lowered, as clearly shown in Fig. 4. Thus, the link 14 functions as a cam when it engages the roller 21 and serves to lift the leafbodily so as to engage the lower surface of the table top. It will be observed that by properly positioning the rollor 21 and by suitably designing the under surface of the link 14, the leaf when lowered will .be forced into intimate contact with the lower surface of the table. Moreover, the normally upper surface of the leaf will be flush with the edge of the table top. Thus, the table will present a very pleasing appearance with its leaf in the lowered position.

It will be understood that the roller 21 will be suitably supported. Thus, I provide a bracket 22 upon which the roller will be It will be obvious that any suitable abutment 21 may be provided, the roller being preferable, however, in that it facilitates the opening and closing of the leaf.

It will-be understood that the leaf will be supported in its extended position by any suitable means. Preferably, however, the leaf will be provided with a suitable jointed brace 23. It will be understood that for very large tables, more than one of these braces 23 may be employed. I j v It will be observed that the link 18 is provided with a projection or abutment 24 which when the table leaf is raised, engages the inner side of the top edge. Thus, the leaf will be secured in its extended positionby reason of the substantially rigid arm, provided by the links 13 and 14, together with the supporting brace 23. i

In operation it will be understood that when it is desired to lower the table leaf, the brace 23 will be broken and the leaf swung about the pins 15, the clearance 20 between the lugs 17 and the abutment 18 providing for relative movement between the links 13 and 14 so that the table leaf will swing clear of the adjacent edge of the table. As the leaf nears its lowered position, the lower surface of the link 14 will engage the roller 21 to force the upper edge of the low-Q ered leaf into intimate contact with the under surface of the table. To raise the leaf, it is simply necessary to swing the leaf in a counterclockwise direction, as viewed in the figure, to its extended position where it will be supported by the jointed brace 23.

While I have described my invention as embodied in concrete form and operating in a specific manner in accordance with the provisions of the patent statutes, it should be understood that I do not limit my invention thereto since various modifications thereof will suggest themselves to those skilled in the art without departure from the spirit of my invention, the scope of which is set forth in the annexed claims.
