TABLE-LEAF SUPPORT.

EiPl-BCIPICATION forming part of Letters Patent No. 338,254, dated March 23, 1886.

Application filed October 10, 1885.

To aZZ whom, it may concern:

Be it known that I, FRANK G. ERLANDER, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Table-Leaf Supports, of which the following is a specification.

The object of this invention is to provide table-manufacturers with a table-leaf support combining the advantages of simplicity of construction, automatic action, great strength, and slight expense.

This invention consists in producing a tableleaf support that will automatically assume the necessary position for supporting a tableleaf whenever the leaf of a table to which it is attached is raised to a horizontal position.

This invention further consists in so constructing a table-leaf support that it cannot be accident] y dislodged, thereby allowing its leaf to drop down.

In the accompanying drawings, which form apart of this specification, Figure l represents a view of a longitudinal central vertical section of a part of the upper portion of a table provided with my improved table-leaf support. Fig. 2 represents a front view of a guide-plate. Fig. 3 represents a view of a longitudinal central vertical section of Fig. 2 through the dotted line X X. Fig. 4 represets a view of a supporting-arm and hingeplate attachment. Fig. 5 represents a view of a longitudinal central partial section of Fig. 4, through the dotted line X X. Fig. 6 represents a view of a modification of Fig. 3.

Similar letters refer to similar parts throughout the several views.

A A A represent, respectively, a tableleaf, table-top, and rail supporting the latter.

B represents a hinge-plate provided with a seniicylindrical recess, B, and the screw-holes B 0 represents a guide-plate having the longitudinal slot 0 and screw-holes O '0 represents a rest.

(3 represents a safety projection.

Serial No. 179,516. (No model.)

0 represents strengthening-ribs.

0 represents oblique upward projecting shoulders.

D represents a supporting-arm, the central portion whereof is increased in diameter for the purpose of obtaining greater strength.

D represents a cylindrical cross-piece,which fits into the recess B of the hinge-plate B, forming a hinge-joint therewith.

D represents a portion of the lower end of the supporting-arm D, double tapered to prevent the same from colliding with the sides of the slot 0 of the guide-plate G.

D represents a cross-piece of the supportingarm D, which serves to retain the lower end of the latter in the slot 0 of the guide-plate C, while allowing it free longitudinal motion. Upon raising the table-leaf A the cross-piece D striking against the shoulders G", prevents the leaf from being elevated too high, which would result in injury to orin the breaking of the hinges securing the leaf to the table. The table-lea'f'A being released,the cross'piece D resting upon the upper side of the guideplate 0, guides the lower end of the supporting-arm D downward underneath the safety projection G and against the rest 0".

I claim- 1. In a table-leaf support, the safety projection C, substantially as described, and for the purpose set forth.

2. The combination, with the guide-plate C, having the longitudinal slot 0 and provided with the rest 0 safety projection O, oblique shoulders C, and strengthening-ribs 0 of the supporting arm D, furnished with the cross-pieces D D, substantially as set forth.

3. The combination, with the hinge-plate B, of the supporting-arm D and guide-plate G, substantially as described,and for the purpose specified.
