ADJUSTABLE CHAIR LEG.

Application filed December To all whom it may concern:

Be it knownthat I, l-InnNDoN L. Mussrenn, a citizen of the United States, and a resident of Seattle, county of King, State of Vi ashington, have invented a new and useful Adjustable Chair Leg, of which the following is a specification.

This invention relates to adjustable legs suitable for use on various articles of furniture but especially tables and chairs.

It has for its particular objects an ad justable leg which may be used on any number of the furniture legs, say two or four, of a table or chair. The use of one or more legs might be desirable on a campers table on uneven ground and the use of two or four on a chair, the whole set of four legs particularly adapted for use on a meehanics chair to adjust its total height or its proportionate front and rear height to suit his exact requirements.

1 achieve the objects outlined and produce an article adapted to the uses specified by the device illustrated in the following drawing, and in which Figure 1 is an approximately full size perspective view of my adjustable leg shown applied to a leg of a chair, though as suggested above it may be used on any furniture leg, and Figure 2 is an optional formation of the adjustable leg bar.

In the drawing the chair leg is designated (1) and it is shown as having rungs (2) broken ed as having no direct bearing on the invention. My adjustable leg is shown at and comprises a. bar (4) having notches (5) formed along one side thereof, and has at its lower end a broadened foot portion (6) rounded somewhat at (7) so as to adapt it to a firm contact with the floor regardless of the angle of the chair or other leg to which it is attached.

The leg is slidably carried by a bracket (8) having an extension tube screwed or otherwise secured to it as at 10), to form an elongated guide for the leg bar, adapting same to be freely moved up or down for adjusting the leg for any desired extension beyond the chair leg.

The bracket has a lug (l1) engaging the lower end of the chair leg and secured thereto by a screw as dotted at (12), also by a screw (23) in each side in a pocket (24) in the bracket, and around the leg extends a flat metal band (13) terminating at either one or both ends in a bolt (14) extending 3, 1923. Serial No. 878,303.

through a hole in a lug (15) formed in the bracket. The bolt or bolts may be drawn up tight by means of the nut (16) to clasp the leg tightly with the band.

In place of a bolt on each end of the band, one only will sufiice, the other end being simply secured by any desirable means to the bracket.

In practice, if the device is used on a chair, the chair legs are cut off to shorten them so that a greater range of adjustability of the device may be realized, and it is thus indicated in the drawing by reason of the lowest rung being so near the lower end of the leg.

To hold the adjustable leg at any desired extension I provide a spring actuated pawl rod having a slanted engaging jaw (17) adapted to engage any of the notches (5) with a ratchet like action permitting the extensible leg to be pulled out to any point but preventing its return. The pawl rod is pivoted at (18) to the bracket and has a leaf spring (19) arranged to bear against the bracket to keep the jaw resiliently engaged with the notches.

To prevent the bar from turning in the slide, 1 provide a slot (20) along one side of the bar and a pin (21) projecting from the bracket engaging the slot. Of course, it is apparent that a square or hexagon bar could be used to avoid the slotting of the round bar, and such a construction is indicated in Figure 2, wherein the same designating numerals are used with exponents.

To lengthen the leg the bar is simply pulled out as mentioned and to shorten it the upper end (22) of the pawl rod is pressed against the bracket to release the jaw from the engaged notch.

By forming the foot of my leg as shown it extends under the chair leg and takes the same position on the floor as formerly occupied by the original leg, while at the same time provides for concealing the apparatus entirely in back of the chair leg in the corner between the rungs of the chair as shown. As will be seen from the drawing the foot (6) is relatively thin and flat, therefore, it is strengthened by a diagonal instep or brace, rib (26). A diagonal slot (27) is formed in the lower rear edge of the bracket to freely receive the brace rib (26) when the foot is pushed up close against the bottom of the bracket, thus adding to the range of adjustability, and I consider this fiat, rearwardly rounding, and upper braced toe an important feature of my invention.

I claim:

1. An adjustable leg for a chair or the like coniprisinga bracket for securing to the chair leg and a rod slidably adjustable through the bracket having a bearing foot projecting laterally from the rod to rest on the floor in a position under the chair leg, said bearing foot having a broadened toe rounded at the under side to adapt it for firm contact With the floor at various angles, an angular brace from theupper side ofsaid toe extending to the rod, and a slot in the lower corner of the bracket adapted to freely receive the brace upon sliding the rod to bring the toe against the bracket.

2. An adjustable leg for a chair or the like comprising a bracket adapted to clamp to the side of the chair leg and having a rod slidably adjustable therethrough for supporting the chair, said bracket having a lug engaging under the lower end of the chair leg.
