COMBINED DESK AND CHAIR.

Application filed September 6, 1916.

To all whom it may concern:

Be it known that I, GEORGE W. MORRI- SON, a citizen of the United States, residing at Lewiston, in the county of Nez Force and State of Idaho, have invented a new and useful Combined Desk and Chair, of which the following is a specification.

The invention relates to combined desks and chairs, and more especially to that class used in schools, or the like, and wherein the desk and chair are connected to form a unit, with the desk for one student attached to and in rear of the seat for another student.

An object is to simplify the construction and reduce the cost of manufacture of such desks, and is particularly designed to improve the structure disclosed in Letters Patent No. 1,200,693, granted to E'. H. Barton and myself October 10, 1916, by eliminating therefrom the additional casting comprising the rearlegs of'the tripod for separately supporting the adjustable seat, and to provide means for the rigid attachment of a single supporting'member to the front face of the nextsucceeding desk support in such a manner as to permit of its ready application thereto or detachment therefrom for the purpose of storage or shipment. V

Another object is to provide a deskand chair support which occupies a minimum amount of floor space, thus avoiding, as much aspossible, corners or places for-dust and dirt to accumulate, and which will, consequently, permit of readily washing, sweeping, or otherwise treating the'floor.

A full and complete understanding of the invention may be obtained from'a considerationof the following detailed description, taken inconnection with the accompanying drawings forming part of this specification; it being understood that while thedrawings show a practical form of the invention, the-latter is not confined to strict h conformity therewith, but may be changed or modified, as long as such changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the claims hereto appended;

In the drawings inwhich like reference characters designate like parts'in eachof' the several figures:-

Specification of Letters Patent.

Patented Dec. 17, 1918.

Serial No. 118,769.

Fig. 2 is an enlarged detail sectional view on the line 22 of Fig. 1.

Fig. 3 is a similar view on the line 3-3 of Fig. 1.

Fig. 4 is a similar view on the line H of Fig. 3.

Fig. 5 is a rear elevation of the desk and chair support, as shown in Fig. 1.

Fig. 6 is a detail horizontal sectional view, on the line 66 of Fig. 5.

In the drawings, 1 represents a desk support having adjustable desk supporting means '2 located at the top thereof and supporting a desk 3 of the construction ordinarily used in schools, or the like, all of which is substantially the same as illustrated in the said Letters Patent. lhe desk supporting means 1 comprises an arched mem ber composed of two spaced, bowed legs 4, having integral flared feet 5 formed at their lowermost extremities to rest upon and be secured to the floor in the ordinary manner. This arch is preferably of flanged construction to lend additional strength and rigidity thereto.

A centrally located upstanding desk supporting post 6 is arranged at the apex of the arch and is preferably formed integral therewith, and having the rearwardly extending vertically disposed marginal flanges 7 for a purpose to be hereinafter described. A vertically disposed slot 8 is formed in the post 6 and extends from an intermediate point thereof to a point adjacent the top extremity of said post 6 and is adapted to receive a screw 9, or other binding means which passes therethrough and enters the aforesaid desk supporting bracket 2, and is adapted to support thesa id desk at any clesired elevation within the limits of the said slot 8, the bracket 2 being guided in its upward and downward adjustment between the marginal flanges 7. The book supporting shelf 11 of the desk is preferably provided with an aperture 12 for the purpose of receiving the upper end of the post 6 within the confines of the said desk.

The desk supporting post 6 is further provided on the face opposite to the marginal flanges 7 with relatively short spaced ribs 13 vertically arranged and in parallel relation to each other. the crown of the arch 1 and have their opposed'face's 1d tapered and are adapted to form a guide way for and'prevent lateral displacement of -a seat supportinglmember These ribs 13 rise from" to be described. Between the ribs 13, there is provided a horizontally disposed lug or projection 16 extending outwardly from the face of the post 6 a distance approximately one half the depth of the ribs 13, said projection being provided with a bolt opening 17 formed centrally of the projection 16 and coinciding with a counter-sink 18 formed in that side of the post 6 opposite to the ribs 13 and arranged midway between the flanges 7. A shoulder 19 is provided at the top of the arch 1 at the point of intersection thereof with the post 6.

The seat supporting member 15 is composed of a suitably flanged bar or casting having the bent upper and lower terminal portions 20 and 21 adapted to fit against the front face of the desk supporting post 6 and the floor respectively. The seat supporting member 15 is thus located in an inclined position, the lower end 21 thereof rising substantially vertically from the floor and adapted to be made fast thereto by screws, or the like, the upper end 20 resting in a horizontal position against thefront face of the post 6 and between the ribs 13, the vertical side edges of said horizontal portion 20 being tapered to fit between the said ribs. An opening 22 is provided in the web of the horizontal portion 20 of the seat supporting member 15, adjacent to the end.

thereof to provide an end wall 23 extending the full widthofthe flanges of the said member 15, which flanges are flared or widened, as indicated at 2 1 along the horizontal portion 20, to lend additional strength thereto, and compensate for the opening.

A recess or groove 25 corresponding in shape and size to the lug or projection 16,

is provided on the vertical terminal wall of the member 15 and is adapted to receive the same when the parts are in applied position, and to lie between the ribs 13 and to rest upon the aforesaid shoulder 19 at the lower edge thereof. A centrally located bolt opening 26 is provided in the end wall of the member 15in registering relation to the bolt opening 17 and is adapted to receive therethrough'the bolt 27, the head 28 of which lies in the counter-sink 1S and is prevented from'turning thereby, and a nut I 29 is applied to the threaded end of the bolt 27 within the opening 22, which opening permits of the ready application and adjustment of the nut 2-9, when assembling-the Parts.

The seat supporting member 15 is provided with means for adjustably mounting the seat 30 thereon, to permit of the upward or downward and consequent rearward or forward movement of the seat to adapt the same to different size occupants, but'since this means is showindescribed and claimed in the aforementioned Letters Patent, it is not demed necessary to describe the same herein in detail and no claim is made thereto. It will be seen from the foregoing that the structure as disclosed in said Letters Patent has been greatly simplified and the cost of production reduced to a minimum, since the heavy casting comprising the rear legs of the seat supporting tripod, as disclosed J therein, has been eliminated, and a single bar or member 15 is used for supporting the seat, resulting in an economy of parts and having a minimum number of points of attachment to the floor, whichv is a great advantage as it facilitates sweeping or otherwise treating the same.

The attachment of the member 15 to the desk supporting member 1 may be readily accomplished by the simple manipulation of a single bolt when the parts are rigidly crown of the arch and integral therewith, a

desk supporting bracket, adjustable means for connecting the bracket to the post to provide for the adjustment of the'desk, an inclined seat supporting member adapted to rest upon the floor and forming with the bowed legs a tripod'support, means for adjusting the chair along said member, and int-erlocklng and securmgimeans between the upper end of said member and the face 7,

of the post for detachably securing said parts together at the point where the post rises from the arch. v-

2. In a combined desk and chair, a desk post, a desk supporting bracket slidably mounted upon said post, means for adjusting said bracket upon said post, a seat at the lower end of the post comprisinga horie V zonta-lly disposed projection formed on the face of the post opposite to that'upon which i the bracket slides, a bolt'hole extending through said projection and post and provided with a counter-sinktherein, a seat sup portmg'member engaging saldseatand pro jection, and a bolt extending through said a hole and having a head in said counter-sink for connecting the seat supporting member to said post and to allow the vertical adjustmentof said ference.
