This invention relates to improvements in eralviews, the numeral 1 indicates the top stools and pertains particularly to an iinproved combination stool and stepladder.

The primary object of the present inven- 5 tion is to provide in combination with a kitchen stool, a device whereby the stool may be readily converted into a three step stepladder, the top of the stool forming the third or top step.

Another object of the invention is to provide in combination with a kitchenstool an attachment comprising a fixed body designed to be secured to the stool beneath the top of the same and a pair of steps hingedly attached thereto and having pivotally connecting the same at their outer edges supporting legs Which, with the steps, may be folded into inoperative position against. the said vbody and beneath the stool top.`

lStill another object-of the invention is to provide a structure of the above described character wherein the steps may be effectively braced when they are in down or operative position so that undersirable movement of the stool and the steps is prevented.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing ofthe drawings but may be changed or inodied so long as such changes or modifications mark no material departure from the salient features of the vinvention as expressed in the appended claims.

1n the drawings Figure 1 is a vertical longitudinal section through a kitchen stool equipped with the device embodying the present invention.

Figure 2 is a horizontal sectional view taken upon the line 2-2 of Figure 1.

Figure 3 is a sectional view through a modified form of step showing the method of running the supporting rod therefor through the body thereof.

Referring more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout thesevof a kitchen stool of ordinary type which top may be formed of wood and is supported upon the four legs 2 which extend downwardly therefrom in divergent relation. r-[nter-'v mediate their ends the four legs of the stool are bracedby the cross bars 3 which at the points of intersectionV are secured together by a suitable bolt and nut 4.

Associated with the stool is an elongated bar 5 which, when constructed of metal as is preferable, is of channel formation as shown in Figure 2, there being the main body portion 6 and the longitudinal side iianges 7, the body portion 6 at the upper end being extended and turned to project at a Suitable angle as indicated at Sfor contact with the under face of the stool top 1 to whichit is attached by a screw 9 or other suitable means.

This angle portion 8 `of' the body of the? channel bar is so disposed with respect to the length of the' bar as to arrange'the bar at the proper degree of inclination under the stool to maintain certain other elements, hereinafter described, in the proper position. The free edges of the flanges 5 are provided at suitable points with. inwardly projecting fins 10 which rest upon the tops of the adjacent stool leg bracing bars 3 andsecured againstthe underside of these bars by thevbolt `v 4 which holds them together, is a brace tongue 11 which, as shown in Figurel, is struck longitudinally from the body portion 5 of ythe channel bar and is bent inwardly in the manner shown to cooperate with the fins` for the maintenance of the bar in the desired position.

Adjacent the lower end of the bar 5 and at a point substantially midway between Vthe Yends thereof the body portion G has struckvv ytherefrom the pairs of ears shown each of which is indicated by the'numeral 12. Between the lower pair of the ears 12 there is disposed one end of a step body 13 which has a dependingsurrounding flange 14 through which the ends of a pivot bar 15 rpasses,'this bar extending beneath the body of the step and having its ends extended through the vadjacent ears 12'as shown in Figure 1. Between the upper` pair of the ears 12 there 1s y means for coupling the step to the adjacentV ears also act as braces when the step is iny positioned a step 16 which, at its inner end, is provided with the depending brace flanges 17 which are disposed between the adjacent ears and which have the pivot pin 18 eX- tended therethrough and through the adjacent ears for maintaining the step in position. These flanges 17 in addition to providing a operative position as the.V abutqthe adjacent outer face of the body o the channel bar 5 in the manner shown in Figure 1. Y l

Across its outer edge 'and eteiided along each side edge at the outer part of thelstep is a flange 19. Between these side portions of the flange 19 there is arranged the upper ends of a pair of step supporting legs 2O which are of channel construction as shown in dotted lines in Figure 2,-each leg having its upper end positioned against the Ainner side of one side flange of the step. A connecting pivot bar 21 passes through the side portions oi the flange 19 and the upper ends of the legs 20 thus securing the legs to the flange, the legs being prevented from moving inwardly on the bar 21 by cotter pins .Q2 which are passed through the bar one adjacent each leg as shown in Figure 2.

The legs S20 extend downwardly across the outer face of the flange 14 formed about the f lower step 18, la pivot bar 23 being passed through the legs at vthe points where they cross the flange and through the flange in the manner shown in Figure 1, to pivotally 'secure the legs to this first or lower step.

From the description thus far given it will be readily seen that by lifting the legs 2O the steps 13 and 16 will be swung upwardly and inwardly on their supporting bars 15 and 18 until they position against the outer face of the channel bar 5. In order to maintain the steps in this raised position-there is secured to the upper end of the baro a spring 24 which is formed of band or ribbon material and which projectsoutwardly from the supporting bar curving downwardly in the manner shown so that the outer edge of the upper step must be forced therebeneath when the step is raised to the position indicated in dotted lines in Figure 1.

In order to permit the legs 20 of the device to move into the proper position beneath the top 1 of the stool the edges of the braces 3 nearest these legs are recessed or cut` away as indicated at 25 and when the steps are raised the legs Q0 position iii these recesses.

In Figure 3 there is shown the method eniployed for connecting a wooden step 26 with the legs 27, which method lconsists in extending the bar 28 through thelegs and transversely through the body of the step in the manner shown so that when the step' is in raised posit-ion the supporting bar 28 will be completely hidden from view;
