TABLE LEAF SUPPORT, No. 334,239. Patented Jan. 12, 1886.
INVEJV'TOR I Attorney N PETERS. Phom-Lilhugmpher. Washingion. D. c.
UNITED STATES WVILLIAM KLINE, OF PIQUA, OHIO.
TABLE-LEAF SUPPORT.
SPECIFICATIONforming part of Letters Patent No. 334,239, dated January 12, 1886.
Application filed November 7, 1885.
To all whom it may concern.-
Be it known that I, WILLIAM KLINE, a citizen of the United States, and a resident of Piqua, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Table-Leaf Supports; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification,'
and in Which- Figure 1 is a perspective view, seen from below, of my improved table-leaf support. Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a perspective view, seen from above, of the support, showing parts broken away, and Fig. 4 is a similar view of the several parts of the support separated.
Similar letters of reference indicate corresponding parts in all the figures.
My invention has relation to that class of table-leaf supports in which an arm is hinged to the rail of the table and passes into a device upon the under side of the table-leaf, which will allow the arm to pass through it when the leaf is lowered, and which will bear against the end of the arm when the leaf is raised; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.
In the accompanying drawings, the letterA indicates a portion of the rail of the table. B is the plate of the table, and G is the hinged leaf, which all may be of any desired construction. A hook-shaped bearing, D, is secured to the outer side of the rail by means of a screw passing through its upper flat end, and the lower end of the bearing is hook-shaped and bears with its end into the rail, while the curved portion E forms a bearing for the transversely-slotted inner head, F, of the supporting or brace arm G. The outer free end of the arm is provided with a cross-head, H, which has arecess or square notch, I, in its outer end, and the under side of this cross-head is cut away at its outer end to form a shoulder, J, facing at the inner side of the square notch, while the ends of the laterallyprojecting arms of the cross-head are formed with laterally-projecting lugs K K, projecting from the outermost (No model.)
corners of the cross-headl A box or casting, L, is secured upon the under side of the leaf, and has the sides of its inner end closed and formed into flanges or lips M, through which the fastening-screws pass, while the outer end of the box is open at the sides, and the bottom of the box is formed with a T-shaped slot, N, through the inner transverse portion of which the arm passes, the inner side of the box being cut away to form a notch, O, at that place for the passage of the arm, the notch being of sufficient width to allow the arm to pass, but preventing the cross-head from passing through it. The transverse portion of the T-shaped slot in the box is of sufficient width to allow the shoulder of the cross-head to drop through it and to bear against its inwardly-facing side, while the laterally-projecting lugs upon the ends of the cross-head rest in the box at the ends of the transverse slot, and it will thus be seen that the shoulder of the supporting-arm, bearing against the inwardly-facing edge of the transverse slot of the box, will support the leaf raised. Thelaterally-projecting lips or flanges of the closed sides of the box form hearings in their upper sides, the said bearings 1? being transverse to the arm and immediately inside of the inner wall of the box, and the ends of the oross-head Q of a T-shaped locking-plate, R, rock in these bearings, the shank of the said plate projecting through the shank of the T- shaped slot in the box, the said shank of the locking-plate being lettered S. The outer ends of thelower edge of the cross-head of the locking-plate are provided with lips T T, and the said lips bear against the inner edges of the laterally-projecting lugs at the ends of the cross-head of the supporting-arm when the shoulder of the same rests against the edge of the T- shaped slot, so that the outer end of the arm cannot be raised by simply pushing upward upon it, the only way of releasing the arm being by raising the shank of the lockingp1ate,which will release the T- head of the arm, and thereupon raising the said T- head out of engagement with the transverse slot, when the arm may slide through the slot in the box and the leaf may be folded down. In this manner it will be seen that the locking-plate, which will be held in place by the gravity of its shank, will prevent the supporting-arm from being lifted out of its place by any accident, the arm supporting the leaf in such a manner that it cannot drop down by any accident.
The entire device is simple and durable, there being only four parts of the entire device, and the only fastening necessary for the entire device is one screw passing through the hookshaped bearing into the table-rail, and two screws into the table-leaf through the lips or flanges of the box, the arm being secured by means of the hook-shaped bearing engaging its slotted inner end, and the locking-plate being secured in its bearings in the inner sides of the fastening-lips of the box, which are closed by the under side of the leaf to which they are secured.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States In a table-support, the combination of an arm pivoted to the table-rail and having its outer end formed with a cross-head having a transverse shoulder upon its under side and a square recess in its outer edge, and lips or lugs at the outer corners of its ends, a box having its closed end secured to the table-leaf and formed with a slot in its rear side, and with a T-shaped slot in its bottom and having transverse bearings immediately inside of the inner side of theboX, and a T- shaped locking-plate having its ends rocking in the bearings and formed with lips upon the lower edges of its ends for engaging thelaterally-projecting lugs of the arm, and having its shank projecting into the slot in the box, as and for the purpose shown and set forth.
In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
XVILLIAM KLINE.
