51 woe whom:

20., WASHINGTON, n. c.




To all whom it may concern:

Be it lmown that we, WALTER D. SoHMITs and EMIL MUUSS, citizens of the United States and Germany, respectively, and both residents of New York city, county and State of New York, have jointly invented a new and Improved Chair, of which the following is a specification.

This invention relates to a chair having a permanent cane seat and a removable auxiliary seat adapted to be superimposed on the cane seat and to be detachably secured to the seat frame.

The construction is such that the auxiliary seat may be readily applied or removed that it is not liable to scratch or otherwise injure the seat frame or cane bottom and that any unsightly attaching means are obviated.

In the accompanying drawing: Figure 1 is a perspective view of a chair embodying our invention; Fig. 2 a plan with the auxiliary seat partly broken away; Fig. 3 a section through the auxiliary seat attaching means, and Fig. 4 a plan of part of the seat frame and part of the cane seat.

A chair 10 of suitable pattern is provided with a permanent seat frame 11 which is overlapped along its inner side by a cane bottom 12 which is secured to frame 10 at 13 as usual. At preferably opposite points there are formed in that section of frame 11 which is overlapped by cane bottom 12 a pair of upright apertures 14 such apertures being alined with corresponding apertures or meshes 15 of cane bottom 12. With the construction described, apertures 14 are readily accessible from the top and are nevertheless so surrounded by the strands of the cane, that they are practically invisible and will not in any way impair the looks of the chair. Upon seat frame 11 is adapted to be placed an auxiliary seat A which when applied covers up the cane bottom and projects partly or entirely over seat frame 11. The auxiliary seat is shown to be of the upholstered or cushioned kind, it being provided with a rigid bottom plate 16 that overlies the cane bottom and extends over the meshes 15 thereof and also over the apertures 14 of frame 11.

Specification of Letters Patent.

Application filed July 6, 1911.

Patented Oct. 10, 1911. Serial No. 637,116.

The batting 17 of seat A is covered by a plurality of textile layers 18, which are tucked under the edges of plate 16 and thus form a pad intermediate the auxiliary seat and the seat frame 11, so that the latter is not liable to be scratched. A lining 19 nailed to plate 16 covers up and protects the edges of this pad as shown.

Depending from each side of plate 16 is a threaded bolt 20 adapted to be projected through the corresponding apertures 15, 14 of seat 12 and frame 11. In order to reliably attach this bolt to plate 16 the latter is provided with a squared opening bushed as at 21 and adapted to snugly accommodate an upper squared bolt section 22. The bolt 'head 23 is covered up by a cap 24 secured to plate 16, so that by the means described, the bolt is held against rotation and is also prevented from piercing batting 17 and covering 18. The lower threaded end of the bolt is adapted to receive a winged nut 25 adapted to be tightened up against the lower side of seat frame 11.

If the chair is to be used with a cane seat, nuts 25 are unscrewed and the auxiliary seat A together with its depending bolts 20 is lifted oif frame 11. If the auxiliary seat is to be used, bolts 20 are passed through the apertures 15 of the cane seat and apertures 14 of frame 11, so as to project with their threaded ends below such frame. The nuts 25 being now applied and tightened up, the auxiliary seat will be securely attached to the chair in such a manner that the cane bottom is entirely covered up and concealed.

It will be seen that by the construction de scribed, the auxiliary seat may be readily applied and removed, that there are no objectionably obtrusive fastening means, that the chair is not weakened for the reception of the auxiliary seat and that when the latter is applied there is nothing whatever to indicate the presence of the fixed cane seat therebeneath.

Though the auxiliary seat is shown to be of the upholstered type, a difierently constructed seat may obviously be used.

We claim:

A chair provided with a permanent seat frame having a pair of apertures, a meshed auxiliary seat with the permanent seat cane bottom secured to the frame and havframe.
