The a'ifm falsdcarif;

to the arm 36 by a hinge 39 having a pintle headed at its top and so upwardly readily removable for convenient hinge breakdown when desired. Said arm 38 is instantaneously releasably pivotally connected to the unit by .a.

spring-pin like the spring-pin 29 aforesaid and the location of which is indicated in Fig. 9 where the same is marked 29'.

The arm 34 is vertically apertured at 46, which aperture registers with an aperture 4| through a metal plate 42 secured as indicated in Fig. 11 to iii the bottom of said arm. aSaid arm 34 also carries a hook 45, forcoactionwith an eye id carried by the arm 38 andthento-hcild the arms 34 and 36 extended asin Fig.1.

The'arms 36 and '38, opposite the location of the hinge,39,-respectively carry hook and eye elements 43 and 44, for'coaction in holding these arms extended as in Fig. 1 and the arms 26 and 28 (of the other device 22) respectivel carry, opposite the location of the hinge 21 similar hook and eye elements 'for coaction in holding these arms extended as in Fig. 1, in which .view the hook and eye elements last-mentioned are hidden behind said arms 26 and 28.

All six arms of the two devices 22 and 23 are of like cross-section, one which is substantially square.

Referring now'to Figs. 1, 4, 5 and 7, the unit 2| is shown as comprising a top 41, askirt 48, three legs '49, and 5|, and a cross-beam 52; such cross-beam having, its upper limit spaced below the undersurface of thetop '41 a, distance about equal to the vertical thickness of the arm 28.

Suitably rigidly secured to the rear side of the cross-beam 52 is rest-block 53, which, together with the cross-beam, provides amounting for thespring-pin 29 andits associated parts.

Referringto Figs. 7 and 8, andparticularly to the latter view, recessiis provided comprising a larger verticalbore 54 'and'below the same and concentric'therewith a smaller bore 55. These bores, transversely thereof, are provided one-half of each in each block 53 and beam 52. The spring-pin 23, having at its bottom. an enlarged head 56, extends upwardly through the bore '55 and thence through thebore 5'4 and thence upwardly through an apertured metal plate 56 secured as by screws. 51 to the tops ofthe block and the beam.

The spring-pin29 is provided with a cross-stud 58 for engaging the plate 56 to limit upward protrusion thereabove of the upper end of the spring-pin, such protrusion yieldingly maintained by an expansible coil spring 59; The spring-pin 29 carries a spacing collar between its head 56 and the bottom of the block 53; to aiford an easy tool or hand 'hold onsaid head for pulling down the spring-pin to disconnect the arm 28 for removal when desired. With the arm 28 in place, as shown in Fig. 8, the upper endof the springpin is rotatively receivedin 'a recess 6| extending up into said arm near-oneend thereof, after said end of the pin 29 passes through an apertured plate 62 suitably attached, by screws 63, to the I Referring to Figs. 1 and 6, the end-table unit 26 is shown as of similar construction to that of the unit 2|. Thus the parts of the unit 2| to which reference characters with primes are applied, correspond, respectively, to the parts of the unit 2| to which reference characters without primes are applied. As will be understood, and as shown in Fig. 6, the rest-block 53 of the unit 20 is opposite that line of extension of the device 23 which is shown in Fig. '1, just as the rest-block .53 is opposite that line of extension of the device 22 which is shown in Fig. l.

The arm 33 of the device 23, retained in the combination while the arm 28 of the device 22 is soretained, has. secured thereto a plate 62' corresponding to the plate 62 of Figs. 5 and 8, and also -a recess corresponding to the recess 6| of Fig. 8, for coaction with the spring-pin 29' in the manner'already noted in connection with the coaction between the plate :62 and the recess 8| with the spring-pin 29.

The table top 4'! of the unit 2! pivotally carries, at its underside near one'jen'd of its straight edge, a hook 64, for-coaction withaneye 65 on the underside of'thev top 41' of the unit 26; and

said top 41 pivotally carries, at its underside near one end of its straight: edge, a hook 66, for coaction with an eye Bl on the underside of the top 47 of the unit 2l; these hooks and eyes for coupling the'two units 26and 2|, straight edge of one against straight .edge. of'the other, asshown in Fig. 3.

Five table leaves are provided, all alike, and each like the three thereof and the two thereof shown in dot and dash lines at68 in Figs. 1 and 2. In the table as herein illustrated, each of these leaves is 12" wide.

In the device 22 the longer arms 24 and 26, and in the device 23 the longer arms 34 and 36, are of such lengths that when the parts are arranged as in Fig. 2 the spacing between the-facing and parallel straight edges of the tops of the units 20 and 2|, is as there shown equal to the sum of the widths of two leaves '68; while'the shorter arms 28 and 38, of the devices 22 and 23, respectively, are of such lengths that, when they are present as in Fig. 1, said spacing between the units 26 and 2| is as there shown equal to the sum of the'widths of all five of the leaves 68.

Operation: With the parts arranged as in Fig. l, for the seating of =14 persons, assume that it is desired to rear-range'the parts as in Fig. 2, for the seating of six persons.

As a first step, there arebodily 'removedthe arms 28' and'38.

Thus to remove thearm -28, it ismerely'necessary to free one end' of the-same from the arm-26 by lifting out the pintle of the hinge 21 andto freethe other end of the arm from the springpin 29 by pulling down on the-'head-56 of the latter. And to remove the arm 38, it ismerely necessary to free one end-of the'samefrom the arm 36 by lifting out the'pintle of the hinge 39,'and to free the other end of the-arm 38 from the spring-pin 29 by a similar pull-down of that 'pin.

Theshorter arms 28 and 38 having been removed, for storage say in'the same place wheresome or all of the leaves 68 are stored when not in use, the only remaining-operations arejinregard to the device 22, to disengage from its eye the hook beyond the hinge 2|-,=-doub1ebackthe arm 26 on the arm 24 at said hinge, and-pivotallymount on the spring-pin 2'9 the end of the arm 24"carrying the plate 3-2,-and, inregard-to-the device 23, to disengage fromits-eye the hook-opposite the hinge 31, double back the arm 36 on thearm 34, and pivotally mount on the spring-pin 29' the end of the arm 34 carrying the plate 42.

The parts then become arranged as in Fig. 2, and when the two leaves 68 are added as there indicated, the table is solidly established, for the proper seating of six persons.

Assuming however, it is desired to transform the arrangement shown in Fig. 1 to that shown in Fig. 3, for the proper seating of four persons, all that is necessary to be done is to remove the arms 28 and 38 as above explained, and then, after disengaging the hooks and eyes opposite the hinges 21 and 31, and doubling back the arms 26 and 36 on the arms 24 and 34 also as above explained, swing the arm-groups 24-26 and 3436 through 90 about the permanently installed pivot pins 25 and 35, respectively.

Thereby the parts are arranged as indicated in broken lines in Fig. 3.

Then, if a single table is desired as in Fig. 3, it is merely necessary to bring together the two units 20 and 2! as there shown and engage the hooks 64 and 66 with the eyes 65 and 61, respectively, as indicated in Fig. 3.

Also, to employ the two units 20 and 2| as individual end-tables, spaced and placed as desired one without regard to the placement of the other, the parts are used as in Fig. 3, but, of course, with the hooks and eyes last-mentioned disengaged.

To prevent endwise mis-alignment of such leaves 68 as are used, as in Fig. 1 or 2, interfitting projections and recesses may be carried by. said leaves, along their long sides, with corresponding provisions along the straight edges 'of the tops 41 and 41 of the units 20 and 2|, according to a wellknown practice in the art of extension-leaf dining tables.

Referring to Fig. 14, there is here illustrated an arrangement which may be used, in relation to the meeting portions of the arms 26 and 28, in

lieu'of the hinge 2! with its removable pintle as aforesaid. Said meeting portions in this view are marked 26 and 28. The portion 28' is shaped to have a transverse end wall subdivision 10, of relatively small height, and therebelow a down.- wardly forwardly inclined main end wall subdivision H, and the portion 26' is shaped to have an end wall subdivision 12 matchable against the end wall subdivision and therebelow a downwardly and rearwardly inclined end wall subdivision 13 matchable against the end wall subdivision Il. For holding this matched relation against lateral displacement, a pair of hooks 14 are pivotally carried by the portion 28', and a pair of coacting eyes are carried by the portion 26 one of which eyes is seen at 15. When such construction is employed, a like construction will be employed relative to the meeting end portions of the arms 36 and 38.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention, as defined in the appended claims.
