KNOCKDOWN SEAT.

Specification of Letters Patent;

Patented Sept. 20, 1910.

To all whom it may concern:

Be it known that we, WILLIAM A. KIRK- PATRICK and Joint E. ROBBINS, citizens of the United States, residing at Greensburg, in the county of Decatur and State of Indiana, and CLIFFORD P. KIRKPATRICK, a citizen of the United States residing at Indianapolis, in the county of Marion and State 0 Indiana, have invented certain new and useful Improvements in Knockdown Seats, of which the following is a specification.

The object of our present invention is to provide a strong and useful seat which may be readily assembled and disassembled, for storage, shipment and the like; or, in other words, quickly and easily transformed from the assembled to the knocked-down condition or vice versa. Said invention will be first fully described, and the novel features thereof pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a perspective view of a piano bench embodyin our present invention; Fig. 2 a central Ion itudinal vertical section of the view thereof; Fig. 3 a detail sectional view at the point where the top and the u per end of one of the legs are joined, and Fig. 4 a detail sectional view illustrating the means of connecting the stay bar and the cross bars by which the pairs of legs are united.

While we have illustrated (and shall describe) this invention as applied to a piano as will be readily understood, be used in various kinds of other seats and structures without departing from my invention. In this structure a top 21 has shallow recesses formed in its under side at points where the upper ends of the legs approach it, and a portion of each of said recesses is occupied by a metal keeper plate 22 having an undercut edge facing the remainder of such recess, all as best shown in Fig. 3. Said plate may be secured in any desired manner, as by screws 23. Each of the legs 24 has secured to its upper end a corresponding plate 25, the projecting toe of which is adapted to pass below the overhangin edge of plate 22. These legs are inserte by being first laced in the position indicated by the dotte lines in Fig. 2, and

then swung down to approximately the positlon they occupy when the structure is finished, as shown by the full lines in said figure, after which they are drawn tightly together by the stay bar which has right and left hand threaded bolts secured in its ends.

In the construction shown, the legs 24 are formed in pairs, which are connected by cross bars 28, and these cross bars are provided with threaded plates or nuts 26, as is most plainly shown in Fig. 4. The stay bar 27 has in its ends the right and left hand threaded bolts or bolt portions 29 and 30, and these are adapted to enter the plates or nuts 26. On account of the right and left hand formation of the threads, a revolving of this stay bar will draw the cross bars 28 tightly against the ends thereof, and at the same time bring the legs 24 to their final or operative position, as shown in the drawings. All that is necessary in order to disassemble this structure is to revolve the stay bar in the opposite direction until the bolts and nuts separate, when the legs can be detached from the body by merely swinging them out to the position indicated by the dotted lines in Fig. 2.

Having thus fully described my said invention what.I claim as new, and desire to secure by Letters Patent, is,

1. A knock-down cabinet structure comprising a connecting member, a pair of legs, and a second connecting member connected to the legs by a pair of oppositely threaded screws, the connection between each leg and the first connecting member comprising two plain plates of substantially the same thickness having their adjacent edges oppositely and matingly beveled, one of said plates being secured to the upper end of the leg structure and the other of the said plates being secured 'to the first mentioned connecting member and lying within a socket formed in said first mentioned connecting member and having one dimension substantially equal to the combined dimensions of the two plates when their beveled edges are mated together, substantially as and for the purpose set forth.

2. In a knock-down cabinet structure, the combination of a pair of separable members one carrying a plain thin plate 25 having a beveled edge, and the other carrying a plain thin plate 22 having a beveled edge mata-ble diana, this ninth dayof August, A. D. one 1c With the beveled edge (if the plate 25), said thousand nine hundred and. nine. last mentioned late 22 ein 'inounte Wit I in a socket fOIl 1 16Cl in the ni ember to Which WILLIAM KIRKPATRICK it is attached and said socket having a di- ROBBINS niension substantially equal to the dimen- OLHFORD KIRKPATRICK sion of the tWo plates When mated together. lVitnesses:

In Witness whereof, We, have hereunto GEO. E. ERDMANN, set our hands and seals at Greensburg, In- HUGH WIOKENS.
