COMBINATION DESK-CHAIR.

Specification of Letters Patent.

Patented Aug. 22, 1916.

To all whom it may concern Be it known that 1, CHARLES IRWIN LAT- TIG, a citizen of the United States, residing at Glenside, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Combination Desk-Chairs, of which the following is a specification.

- My invention relates to improvementsun combination desk chairs, the object of the invention being to provide a strong and rigid chair with improved desk supporting means, whereby the desk may be adjusted vertically or positioned at any desired angle, and also move toward and away from the occupant of the chair to enable the desk to be positioned exactly as desired.

A further object is to provide a chair in which the vertical and horizontal supports are of metal pipe connected by angles and T-couplings, and rigidly supporting the chair seat and the desk, the latter capable of adjustment vertically and angularly as well as horizontally to suit the occupant of thechair'.

A further object is to 'provide a cha r of the character stated which will be neat and attractive in appearance, comparatively cheap to manufacture, and strong and durable in use.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and -arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating my improved combination desk chair. Fig. 2 is a view in front elevation of Fig. 1. Fig. 3 is a top plan view. Fig. 4 is a View partly in elevation and partly in section, the section being taken on the line 1-4: of Fig. 2. Fig. 5 is a top plan view with the desk removed, the position of the desk being indicated by the dotted line. Fig. 6 is a fragmeigtary view in transverse section on the line 66 of Fig. 1. Fig. 7 is a view in section on an enlarged scale illustrating the clamp 22, thesection being taken on the line 7-7 of Fig. 1. Fig. 8 is a fragmentary view on an enlarged scale in section on the line 8-8 of Fig. 2.

1' represents a chair seat which is supported on horizontal rods 2, the latter se and 7 and a horizontal parallel tubular guides are at the rear of the seat and extend above the seat, and are connected by cross bar 5, which is connected by a board 6 with seat 1, and constitutes the back of the chair.

The two rear rods 3 constitute chair legs, while thg rod l at the left of the chair constitutes one of the front legs. The other red corresponding to rod 4: and which for clearness of description I have given the reference numeral 8, is located parallel with a pro ected leg 7 This leg 7 also consists of a rod extending to the floor. Horizontal rods 9 located an appreciable distance below rod 2, connect the several vertical rods 3, 4:, 8,

I rod 10 at the right hand side of the chair, connects the rods 3, 8, and 7, constituting an arm of the chair.

The several rods above referred to are of ordinary metal pipe connected by couplings 11, certain of these couplings being T-couplings, and other angles as is necessary in accordance with the location. This hollow rod or pipe construction insures a strong and rigid chair, and in addition provides two at the right hand side and front of the chair for two adjustable posts 12 and 13. These posts 12 and 13 fit snugly within tubular rods 8 and '7, and are adjustable vertically in the tubular rods as will be hereinafter explained. The posts 12 and 13 at their upper ends are connected by T-couplings 1 1, with horizontal,

rods 15. The rods and the Tcouplings have rigid connection. The rods 15 support a desk 16, which latter is provided on its lower face with channel guides 17 receiving the ends of rods 15 and adapteddio slide on the rods to adjust the desk horizontally toward and away from .the back of the chair.

A toggle lever 18 connects the two rods 15. This toggle lever, at one end, is pivotally connected by sleeves 19'with the rods 15, and these sleeves are secured against movement longitudinally of the rods. The other end of the toggle lever is connected by sliding sleeves 20 with the rods 15, so that while the toggle levers permit the rods to move relative to each other and vary the distance between the rods, such toggle lever prevents any possibility of the rods moving out of parallelism.

As above stated, the posts 12 and 13, which lar rods 8 and nected by sleeves 25 with the rods 15, andwhile the construction of links and clamp are precisely alike for the front and rear rod 15, the links 21 of the rear rod 15 are shorter than the links of the forward rod 15, as the rear rod 15 is adjusted only to vary the height of the desk, while the front rod 15 is adjusted to vary the angle as well, and requires a greater length of adjustment.

Under the seat 1, I. locate a sliding drawer 26 having a handle 27 thereon to move the same. The drawer 26 is supported on the tubular framework above described, and in addition is supported by a transverse rod 28, and has a clip 29 mounted to slide on the rod 28, said clip limiting the outward movement of the drawer to prevent it from being entirely withdrawn.

While I have illustrated the desk in a horizontal position, it is to be understood that it may be inclined as desired by raising and lowering the front clamp 22, and the height of the desk may be varied by raising and lowering both clamps 22.

The position of the desk relative to the occupant of the chair may be varied by sliding the desk onthe rods 15, and hence each desk can be positioned precisely as desired.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the preccise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, What I claim as new and desire to secure by Let ters Patent is:

1. The combination with a chair having vertically adjustable posts at one side, horizontal rods supported by the posts, a desk mounted toslide, on the rods, and a toggle lever connecting the rods, substantially as described.

2. The combination with a chair having vertically adjustable posts at one side, horizontal rods supported by the posts, a desk mounted to slide on the rods, a toggle lever connecting the rods, and said toggle lever having fixed pivotal connection with each rod and having sliding pivotal connection with each rod, substantially as described.

3. The combination with a chair having vertically adjustable posts at one side, horizontal rods supported by the posts, a desk mounted to slide on the rods, a toggle lever gle lever pivotally connected to the foursleeves, substantially as described.

4:. Th combination with a chair having vertical tubular guides, posts telescoping in the guides, horizontal rods supported by the posts, a desk mounted to slide on the rods, devices connected to the rods. and adjustably secured to the tubular guides, and a toggle lever connecting the rods, said toggle lever at one end movably connected to the rods, substantially as described.

5. The combination with a chair having vertical tubular guides, posts telescoping 1n the guides, horizontal rods supported by the posts, a desk mounted to slide on the rods, clamps adjustable on the tubular guides, links connecting the clamps with the rods, and a toggle lever connecting the rods, said togglelever at one end movably-connected to the rods, substantially as describedF-p l 6. The combination with a chair having parallel vertical tubular guides at onefjside of the chair, of posts telescoping in; the guides, horizontal rods secured to the upper ends of the posts, a desk having guides on its under face receiving the ends of the rods and slidably mounted thereon, a toggle lever connecting the rods, and means forsecuring the posts at various adjustments in the tubular guides, substantially as described.

7. The combination with a chair having parallel vertical tubular guides at one side of the chair, of posts telescoping in the guides, horizontal rods secured to the upper ends of the posts, a desk having guides on its under face receiving the ends of the, rods and slidably mounted thereon, a toggle lever connecting the rods, clamps slidably mounted on the tubular guides, and links connecting the clamps with the rods, substantially as described.

8. The combination with a chair having vertical tubular guides, of posts telescoping in the guides, horizontal rods secured to the upper ends of the posts, a. desk having guides on its under face receiving the ends guides on its under face receiving the ends 139 1 of the rods and slidably mounted thereon,
