Application filed October 1, i919. Serial No. 327,724.

` primarily intended as a chair-base.`

The principal objects of the invention are to produce a base for the purposes mentioned, which while comparatively inexpensive and simple to manufacture, yet, by reason otite peculiar novel construction, is possessed ket very great strength and durability and is capable of performing its lfunction of a base and 'or sustaining excessive Weight Without danger ot becoming loosened at its joints and lconsequently spreading and collapsing.

"With these and other objects in view, the

invention consists of a chair or other base v formed of Wood, the inner .ends of the legs ot which are provided with a. series ot pret-- .erabl-y .reduced parallel spacedapart ten-V fons arranged in vertical series andftorining intermediate inortises, the inner walls ot which are .at right` angles to ,the vertical sides'oi the tenons, and in intermediate conn ynesting filler-blocks, substantially trianguv 'fla-r .in cross-section and having alternating .oneof the legs; Y f

`Fig.` 3, is a similar view ot one o'ltlie contenons and mortises, the former being of such shape as to enter between the tenons of the legs and `occupy lthe niortises thereof,v

the yopposite sides of said Eller-blocks hav- :ing external shoulders overlapped or engaged -by corresponding shoulders produced at'tlieopposite sides of the legs, caused by a ,lateralreduction of the tenons of the latter, `whereby a Withdrawal of said blocks is successfully resistedby the legs.

. Referring to the-drawing: Y

Figure 1-is a top-plan view oit a baseL constructed in accordance with my invention, the outer ends of the legs being broken away;

` llig. 2, is a detail in inner end elevation of necting iller-blocks;

Fig. 4, is atop-plan vieiv ot the inner porf tion of one ofthe legs; `and Y Fig. 5, is a detail inplan of one ott thecon- ,nccting filler-blocks.;

Similar numerals ont reierenc'e indicate similar partsy in all the figures of the draiving. i

'The legs, l, may be oi? any style or design desired, and each is provided at its inner end with a vertical series of spacedapart .longitudinally disposed tenons, 2, of uniform thickness, and coinbining'to produce intermediate transverse ,nortises 3. rlheends of these tenons are squared or at a right angle to the leg on which they are vformed, as indicated by thedotted lines a, (Fig. 1,) and as shown by iull lines, Fig. 4i, the sides of said tenons arepreferably parallel With each other and also with the lsides ot.'

i the legs on which they are formed.

The tenons are somewhat reduced laterally, as compared ivith the legs on which they are formed, so that there is, as a result of such reductions, formed at the opposite sides oi' each leg, at its juncture with the tenons, right ysingularly disposed vertical stop-shoulders al. t The connecting filler-blocks, (shown in detail in Figs 3 and 5,) are of such shape in cross-section as Willadapt them to fity snugly between the verticalk sides of the tenons of tvvo adjacent legs and in advance of `the'shoulders 4L thereof. To this end, the

with a vertical' shoulder, 6, corresponding f 4with and adapted to .be overlapped or engaged by the shoulder, 4, of the adjacent legsl; so that, as Will be obvious, the parts having been assembled, it ivill be impossible `for the blocks to berenioved without a pre- The-tenonsot.thelega `being .formed as l' shown, tor the purpose ot simplitying the operations by which they are produced, do not interlace or connect, but simply nieet at their inner corners, as indicated by dotted lines in F ig. l. For connection ot the legs, the connecting liller-blocks are depended rpon, each block, as will be seen, overlapping and occupying substantially ono-halt oi the area of the tivo adjacent legs. The tenons ot the connecting iller-blocls are at variance er staggered with relation to the tenons ot the legs, so that `when the legs and blocks are assembled, the upper and lower surfaces oi these parts are flush.

lt will be understood thatJ there may be employed upper and lower metal-plates, ordinary screws being inse ted through the plates and into the tops and bottoms oi the legs, for the purpose ot preventing the latter `trom spreading under the Weight or load. As is usual, said plates may or may not support a metal hub tor the purpose olf accommodating the supporting -standard rising from the base and adapted to support a chair-seat, costunier, table, or other article.

The tenons and other portions oi the legs and blocks, the surfaces of which moet, are glued together, at'ter which the base, as thus formed, and previous to the application of the upper and lower plates, `is bored centrally, as at 9, such bore being i'ormed'pa-rtly in the ends of the tenons ot the legs and partly in the tenons et the blocks. It preferred,however, the boring operation may be omitted, so that there will be left a bore octagonal in cross-section, Jformed `by the meeting or inner ends of the tenons and legs. Y

From the foregoing description in connection with. the accompanying drawing, it will be apparent that I have produced a chair-base oi' neat design and one possessing very great strength and tendency to resist spreading under all ordinary circumstances and conditions, and wherein the principle oi interlacing the connecting-blocks with the legs is carried out with as little expense'in `the operation or' manutacture as possible, the saw-cuts being all. straight and there being toi-ined no small shoulders and recesses tor the purpose oi" fitting the parts and rerunring additional time-consuming opera- `fit-ions. rMoreoveiii', the sides of the tenons oi' the legs being parallel Vto the sides of the legs themselves and not made Wider for the purpose of interlacing with adjacent legs, results in a saving` ot material in forming said legs; so that, as will be obvious, While my base is capableoiv sustaining a maxi-v mum load without danger of spreading and possesses unusual durability, yet it iscapable of being manui'actured at a reasonable cost, there being unnecessary in such manu-` facture of anygexcess'oi operations.

it u'ill be noted that the grain of the Wood Yfrom which the connecting filler-blocks are formed disposed .lengthwise the block, which, as will be apparent, disposes said grain at an angle to the grain of the Wood from which the legs are formed, sothat by such disposition.. the greatest strength is secured. It' desired, doivel-pins or screws may be inserted through the interlacing tenons or' the iiller-blocks and legs, but it is thought merely gluing them together will afford ample security in connection with the top and bottom plates generally used.

Having kdescribed my intention, what l claim is:

l. A chair or other base, comprising a series ot legs having at their inner ends inwardly disposed tenons, laterally reduced to iorm opposite vertical shoulders at the juncrures oi2 the tenons and legs and spaced apart to produce intermediate transverse inortises, and connecting filler-blocks arranged between said legs, said iillerblocls having their opposite outer faces overlapped by the vertical shoulders of the legs and having their inner sides` provided With a series oit tenons spaced apart to form intermediate mortises, said tenons being staggered with relation to the tenons of the legs and oiferlapping the same by entering the mortises thereof.

2. A chair or other base, comprising a series of legs having at their inner ends inwardly disposed tenons, and connecting filler-blocks arranged lbetween said legs, said iller-blocks having their inner `'faces proided With a series of tenons spaced-apart to form intermediate mortises, said tenons being staggered with relation to the tenons of the legs, the sides of the tenons of tWo adjacent blocks meeting and abutting in the inortises ot the legs in which they are located andparalleling each other.

3. A chair or other base, comprising a series of legshaving at their inner ends inwardly disposed tenons and at the juncture el the same with the legs provided with vertical shoulders, and connecting filler-blocks arranged between said legs and having their opposite sideedges overlapped by said shoulders of the legs, said filler-blocks having their inner faces provided with a series of tenons and intermediate mortises, staggered with relation to those or' the legs7 said tenons of the filler-blocks being laterally disposed so as to engage the inortises oi? the legs.

ll.
