EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 758,755, dated May 3, 1904.

Application filed April 4, 1903. Serial No. 151,141. (No model.)

T0 06/ wlwm it mag concern.-

Be it known that I, GUS'IAF G. JoHNsoN, a citizen of the United States, residing at inburne, in the county of Clear-field and State of Pennsylvania, have invented a new and useful Improvement in Extension-Tables, of which the following is a specification.

This invention relates generally to extension-tables, and more particularly to a knockdown or folding table, the object being to pro vide a simple and efficient construction of extension-table in which the corner and center legs can be folded so that the entire table can be packed into a small space.

Another object of the invention is to provide a horizontally-zuljustable center leg which can be moved as occasion may require, and a still further object is to provide a table having folding legs which can be quickly and easily turned up to a vertical position and securely locked.

\Vith these various objects in view the invention consists, essentially, in providing legs connected to the bottom of the table by hinges, each leg carrying an apertured spring-plate adapted to engage a catch or keeper secured to the bottom of the table adjacent to the said leg.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claim.

In the drawings forming part of this specification, Figure l is a perspective view of a table constructed in accordancc with my invention, the legs being folded. Fig. 2 is an inverted perspective view showing the legs open and locked, the table being ready for use. Fig. 3 is a vertical sectional view taken through the table, the legs and connections being shown in elevation. Fig. 4. is a sectional View taken through the table and central leg. Fig. 5 is a sectional view on the line 5 5 of Fig. 4. Fig. 6 is a detail perspective View of the sliding block which carries the central leg. Figs. 7 and 8 are detail perspective views of the catches or keepers. Fig. 9 is a detail perspective view of the spring-plate carried by each leg.

Referring to the drawings, A indicates two sections of the table-top provided with the usual sliding connections B, secured to the under side of the top, and connected to each pair of slides adjacent to their outer ends are the strips C, to which the corner-legs D are connected by means of hinges E, one leaf of the hinge being secured to the strip and the other leaf of the hinge secured to the leg adjacent to its upper end. It will be noted, however, that a small portion of the leg projects beyond the hinge, and this projecting portion fits into the socket C, produced in the strip, thereby providing a rigid joint between the leg and table when the said leg is turned to an upright position, and in order to securely lock the legs in such position I provide each leg on the side opposite the hinge with a spring-plateF, having an aperture F adjacent to its free end, which aperture is adapted to be engaged by a catch or keeper (Jr, secured to the strip 0 adjacent to the end thereof. Each spring-plate F is also provided with a lateral extension F", by means of which the said plate can be pressed against the leg for the purpose of disengaging the catch or keeper when it is desired to fold the legs.

It will be noted that the legs are so hinged that they fold at right angles to each other, thereby avoiding any crossing. In case the center leg is employed the said leg H is hinged to a sliding block I, which slides within a slotted strip K, said block having side grooves I, in which fit the members of the slotted strip K. The block I has a recess 1 which receives the upper end of the leg H, and a keeper G is also attached to said block for the purpose of engaging the spring-plate carried by the central leg. By having the block I slidably connected to the strip Ii the leg can be arranged at any desired point when in an upright position, and, furthermore, when it is desired to fold the said leg the block can be moved back to its extreme position before the leg is turned down, and consequently when the center and the adjacent corner legs cross each other it will be adjacent to their tapered ends, and the uppermost leg will not be held elevated to any considerable extent. Thus it will be seen that I provide a table in which the legs can be folded so as to provide an exceedingly compact article which may be stored in a small space, and, furthermore, by providing a table in which the legs can be quickly and easily folded without removing them from the table the said table can be easily carried up narrow stairways and passages.

Other advantages of my invention will be into the sockets when the legs are in a vertical position, a central transverse strip parallel to the end strips said strip being longitudinally slotted from one end' to a point adjacent the opposite end, a grooved block adapted to slide in the slot of the last-mentioned strip, a table-leg hinged to said block, two of the legs hinged to the end strips being adapt-- ed to fold longitudinally on said strips, the leg hinged to the sliding block being adapted to fold on the central strip, the remaining legs being adapted to fold transverse to and rest on the central strip, and means for locking the legs in a vertical position.
