TA B L E --L E G SPECIFICATION forming part of Letters Patent No. 321,907, dated July 7,1885.

Application filed February 5, 1395. (N model.)

I0 all whom it may concern: surface. This construction may be more read- Be it known that I, OLIVER. F. MITCHELL, ily understood by reference to the drawings,

a citizen of the United States, residing at in which Merrill, Lincoln county, WViseonsin, have in- Figure 1 is a side view of a table-leg emveuted new and useful Improvements in bodying my invention, taken from the inner Table-Legs, of which the following is a speciside. Fig. 2 is a longitudinal section of the fication. same in a position beneath a table. Fig. 3 is In the useof some kinds of tables it is rea top view of the leg; Fig. 4., a plan view of quired that they be exactly level, any uneventhe foot for the leg.

[ ness or inequality of level destroying their use- The reference-numeral 1 indicates the body fulness. This is especially the case with that of the leg, at the top of which is formed a reclass of tables typically known as billiardcess, 2, open on two sides but bounded on tables. the other two sides by walls 3, forming part Such tables as now ordinarily constructed of the leg. From this recess an aperture 1 are made with slate or marble beds, the beds passeslongitudinallythrough the leg toalower consisting of several sections carefully trued recess, 10, of a size and shape to receive a nut, 6 5 and joined at their edges. To properly level 7. A bolt, 4, having a head, 5, of a shape to and adjust such tables without disturbing the afford means for manipulation with awrench, joints or lines of union of the sections of the passes through the aperture in the leg, and has 2O bed is a tedious operation, requiring care and its lower end screw-threaded, as at 6, to engage patience. with the nut 7. The leg supports the table 11 The object of my invention, therefore, is to upon the walls 3 of its recess, these walls befurnish means by which said tables may be ing on the outer or visible sides of the table, readily leveled and adj usted,while the danger so that the recess 2 is concealed, the leg being 2 5 of disturbance of the sections at their lines of joined to the table by dowels or pins 12, or in union is reduced to a minimum. In order to any other suitable way. It follows that whenaccomplish this, I form a recess at the top of ever it is desired to level a table provided with the leg, open on its two interior sides, but legs of this construction it is only necessary, bounded on the two outer or visible sides by in order to cause the necessary variation in the 0 walls forming portions of the leg, while the height of the bed or base, to simply turn,

bottom of the leg is recessed to receive a nut. through the medium of the head 5, the bolt 4, An aperture is formed longitudinally through which thereupon is projected (more or less, as the leg from the top to bottom recess, through the case may be) beyond the nut 7, the hearing which is to pass a bolt. To this bolt is atof the legsland table upon the floor being only 35 tached a head concealed within the upper rethrough the bolt 4 and nut 7.

, cess, while the lower end of the bolt is screw- In order to give a firm bearing for the end threaded and passes through a nut in the lower of the bolt, and to prevent lateral movement'or recess, the length of the bolt being such that displacement, I prefer to use a foot, 8, thereits lower end passes beyond the lower end of with. This foot is preferably of cast-iron, al-

0 the leg. From this it will be readily underthough it may be of any desired material. It

stood that if, by means of the head in the upper is formed with a slight depression or concavo recess, the bolt be turned, it will, through its ity, 13, in which rests the end of the bolt 4, coaetionwith the nut in the lower recess, raise while its under side is roughened or is proor lower, as the case may be, the table resting vided with a few small teeth or projections, 9

5 upon the upper end of the leg. 9,which taking into the floor render lateral In practice, in order to prevent any slipping movement impossible. It is of course to be or lateral movement, I prefer that the lower understood that all the legs of a table which end of the bolt shall rest upon a bed having is desired to be level and kept level are to be upon its under side projections or a roughened of this construction. If they are so, the leveling becomes a comparatively easy and simple matter, as the smallest possible variations are attainable by the use of the screw-bolt without any jar to the table itself, and changes of level of any side or part may be made so gradually and easily as to obviate the danger of starting any of the bed-joints or destroying the absolute and necessary accuracy of the union of the bed-sections.

I am aware that various screw devices have been used in connection with table-legs for the purpose of leveling the table. For instance, a two-part leg has been used,with a screw passed through the upper section into and terminating within the lower section, said screw being provided with a head having sockets for the insertion of a tool from the outside of the leg to turn the screw. In this form a space is formed between the two sections of the leg when an adjustment is effected. There has also been used a screw passed through. the body of the table and the leg, provided at its lower end with an adj ustingnut. In such form the table must either first be lifted before turning the nut, or else the nut be turned while in contact with the floor. There has also been applied a nut with projections on its side to the screw-threaded end of the leg, the nut having a bearing 011 the inside of a socketplate resting upon the floor.

My invention differs from said several constructions in having a single bolt passed en tirely through the leg, access being had to the head of the bolt at the upper end of the leg, and a nut being applied to the threaded end of the bolt inside of the lower end of the leg and the lower end of the bolt resting upon a plate, whereby the construction is made very simple, and the adjustment can be effected without the necessity of first lifting the table and without injury to the floor.

Having thus described my invention, what I Claim is 1. The combiriation of a table-leg having recesses, one each at its top and bottom, the top recess opening at the side of the leg, an aperture connecting the recesses, a threaded bolt passing through said aperture, a nut applied to said bolt within the lower recesses of the leg, and a plate having projections on its lower face and a concavity in its upper face for the end of the bolt to rest in, substantially as described.

2. A table-leg consisting of the solid body 1, having recesses 2 6, connected by an aperture, the bolt 4, having head 5, and the nut 7, substantially as described.

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

OLIVER F. MITCHELL.
