EXTENSIBLE TABLE-LEG.

Specification of Letters Patent. Application filed February 2, 1912. Serial No.

1' 36,658. Patented June 215, 1912.

To all whom it may concern.

Be it known that I, JAMES T. GREGORY, a citizen of the United States, residing at ashington, in the District of Columbia, have invented new and useful Improvements in Extensible Table-Legs, of which the following is a specification.

An object of the invention is to provide an extensible table leg for adjusting a table to correct-for the unevenness of the floor so that the table top will lie in a horizontal plane.

The invention embodies among other features, a device which, aside from adjusting a table toprelatively to the floor can be operated to increase or decrease the distance of the table top from the floor, the various exposed parts of the device being preferably arranged and constructed in an artistic manner to present a neat and effective appearance so that the complete table leg will appear as an ordinary solid table leg such as is .now generally used to support tables.

In the further disclosure of the invention, reference is to be had to the accompany ing drawings constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a side elevation of a table provided with the improved table legs, one of the table legs being adjusted so that the table top will lie in. a horizontal plane, the dotted line denoting the degree of adjustment of the mentioned table leg relatively to the other table legs of the table. Fig. 2 is an enlarged vertical sectional view of the table leg. Fig. 3 is an enlarged horizontal transverse sectional View taken on the line 33 in Fig. 2. Fig. 1 is a perspective View of one of the sockets. Fig. 5 is a perspective view of the screw.

Referring more particularly to the views, use is made of a table 10 having a top 11 and legs 12, the table 10 being provided at the corners thereof with blocks 13 arranged in depending relation to the table top 11. For the purpose of simplifying the descrip tion of the extensible table leg I will describe one of the table legs, it being understood, however, that invariably four table legs are included in a table, such as the table 10. The block 13 is provided with an upwardly extending opening 14 and secured to the under side of the block 13 and extending therein is a tubular socket 15, the said socket being provided with threads on the inner periphery thereof with the lower or outer surface of the socket arranged to fit flush with the under side of the block 13 as shown. A screw 16 is provided with threads 17 on the upper end thereof and. the screw is mounted in threaded engagement with the socket 15, a portion of the upper end of the screw being adapted to extend through the socket and into the opening 14 of the block 13.

A tubular turning member 18 is mounted slide upon the screw 16, the screw being extended entirely through the member, the said member being provided with a plurality of oppositely arranged grooves 19, extending longitudinally to the turning member to slidably receive the outer ends of a locking lug 20 formed on the screw 16, intermediate the ends thereof so that when the member 18 is turned, the screw 16 will turn therewith, the turning member 18, however, being slidable longitudinally to the screw as mentioned. A tubular filler member 21 is slidably mounted on the screw 16 with the upper end of the filler member adapted to engage the lower end of the turning member and a tubular foot member 22 is mounted beneath the filler member 21, the mentioned screw 16 being adapted to extend through the foot member, the said foot member having secured thereto a tubular socket 23, provided on the inner periphery thereof with threads 24 adapted to be engaged with threads 25 formed on the lower end of the screw 16, the mentioned threads 25 being spaced a distance from the extremc lower end of the screw 16 as shown, with the mentioned lower extremity of the screw 16 normally extending downwardly beyond the lower end of the foot member. The filler member 21 can be of any convenient length proportionate to the length of the screw 16 and is provided to complete the leg 12 and aid in supporting the turning member 18.

hen it is desired to raise that end of the table top, on which is mounted the table leg described, the turning member 18 is grasped and rotated, thus rotating the screw 16 to unscrew the same from the socket 15, the filler member- 21 and foot member 22 being adapted to turn with the screw, as will be readily understood. Now if it is desired to raise the table top a distance of one inch, the turning member is rotated until the distance tended below Copies of this patent may be obtained for between the upper end of the turning member and the lower end of the post 13, is equivalent to one inch. The turning member 18 is now held rigid to prevent the same from turning, thus through the medium of the locking lug 20, retaining the screw 16 in rigid position and the foot member 22 is grasped and rotated toward the right, thus screwing the foot member upwardly on the threads 25 to cause the lower end of the screw 16 to extend below the foot member one inch plus the distance that the screw exthe foot member before the various parts of the device were operated to raise the mentioned end of the table top, it being understood that when the foot member 22 is operated as mentioned, the foot member will move upwardly on the screw, thus carrying the filler member upwardly so that the upper end of the turning member 18 will again engage the lower end of the post 13, the upper end of the filler member 21 being in engagement with the lower end of the turning member 18 with the upper end of the foot member 22 engaging the under side of the filler member 21.

When it is desired to lower an end of the table top the reverse procedure takes place and the foot member 22, in this instance, is turned toward the left, it being understood that the screw will not rotate, the turning member 18 being stationary. The turning member, however, will slide downwardly upon the screw as the foot member is rotated and assuming that it is desired to lower the table top one inch, the foot member is rotated until the space between the upper end of the turning member and the lower end of the block 13 is equivalent to one inch. The turning member 18 is then grasped and rotated toward the right thus operating the screw so that the upper end thereof will move upwardly into the opening let and the table leg will then be shortened one inch, as desired.

My device is particularly adaptable for use on pool and billiard tables, and although for the purpose of describing the invention I have shown the same applied to a table, it will be understood that I do not limit myself to the use of my device in connection with tables only, the device being also applicable to other articles of furniture. It will be further seen that the outer surface of the block 13, the turning member 18, the filler member 21 and the foot member 22 can be suitably designed so that the complete table leg will form a neat and efiective appearance and it will be further understood that if desired, the screw 16 can be moved upwardly a suiticient distance to permit the under side of the foot member 22 to engage the floor so that the foot member 22 will constitute a caster or rest for the entire table.

I claim 1. In an extensible table leg, the combination with the block of a table, of a threaded socket secured to the block, said block being provided with a longitudinally extending opening, tend through the said socket with an end of the screw extending into the said opening, a tubular turning member slidably mounted on the said screw, means on said screw and engaging the said turning member for rotating the screw when the turning member is rotated, a tubular filler member slidably mounted on the said screw, a tubular foot member and a socket secured to the foot member and threadedly engaged by the said screw, the said'screw being adapted to normally extend beyond thelower end of the said foot member.

2. In an extensible table leg, the combina tion with the block of a table, of a screw threadedly mounted thereon, a turning member slidably mounted on the said screw, means on the said screw and engaging the said turning member for rotating the screw when the turning member is rotated, a filler member mounted on the said screw and a foot member threadedly mounted on the lower end of the said screw.

3. In an extensible table leg, the combination with a screw for threaded engagement with the block of the table, of a foot member threadedly mounted on-the said screw, a turning member mounted to slide on the screw and interposed between the said block and the said foot member and means for rotating the said screw when the said turning member is rotated.

4. In an extensible table leg, the combination with a screw tor threaded engagement with the block of the table, of afoot member threadedly mounted on the said screw, a turning member mounted to slide on the a screw mounted to threadedly exscrew and interposedbetween the said block and the said foot member and a locking lug formed on the said screw and extending into grooves on the said turning member for imparting rotation to the said screw when the said turning member is rotated.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES r. GREGORY.
