WILLIAM SHERMAN PHILLIPS, OF CAMERON. WEST VIRGINIA.

CHAIR.

To all whom it may concern:

Be it known that I, WILLIAM SHERMAN PHILLIPS, a citizen of the United States, residing at Cameron, in the county of Marshall and State of West Virginia, have made certain new and useful Improvements in Chairs, of which the following is a speclfication.

My invention is an improvement in chairs, and consists in certain novel constructions, and combinations of parts hereinafter de scribed and claimed.

The object of the invention is to provide a chair, which will fold up under a table or other support out of the way, when not in use, by means of a spring and which may be easily drawn out into position when required, and will be locked in such position by its own weight.

Referring to the drawings forming a part hereof: Figure 1 is an end view of a portion of a table provided with two chairs, Fig. 2 is a plan view of the telescoping arm, and its connections, Fig. 3 is a perspective view of the same, Fig. 4 is a side view, partly in section, of a portion of the chair, Fig. 5 is a similar view of the outer section of the telescoping arm, Fig. 6 is a plan view of the bracket, and Fig. 7 is a perspective view of the plate for connecting the bar to the table.

The embodiment of the invention shown in the drawings comprises a table, which may be of any preferred construction, and as shown in the drawings, consists of a top 1, supported by legs 2, and the table is provided near each side with the usual extension slide 3, having on its inner face the undercut groove 4. A bar 5 is provided near each end with a plate 6, connected to the bar by a bolt 7, which passes through registering openings in the bar and plate, and the free end of the bolt is engaged by a wing nut 8. The inner end of the plate is bent at a right angle to the plate as at 9 and engages the bar, while the other end is bent slightly toward the bar as at 10 and rests in the undercut groove as shown in Fig. 1. At approximately the center of the bar, a depending arm 11 is arranged perpendicular to the bar, and a bracket plate 12 is arranged on each side of the arm, each of said plates having at its upper end an angular portion 13, which is secured to the bar by rivets 14, and at its lower end an offset journal pin 15. A bearing 16 connected with a bracket is j ournaled on each pin, and secured in place by a nut 18.

Specification of Letters Patent.

Application filed May 14, 1909.

Patented May 17, 1910. Serial No. 495,960.

The bracket consists of spaced plates 17, connected at each end by bolts 18, 19, and on one of the bolts 18 is journaled a pulley 20, and on the other is journaled, a bearing 21 on a hanger 22, connected with the outer section of a telescoping bar 23, provided with feet 24.

A link 25 is pivoted by one end to an eye 26 on the hanger, and the other end of the link is bent slightly as at 27, and provided with an opening in which is secured one end of a chain 28, and the other end is connected with a hook 29 on a coil spring 30, the chain passing over the pulley. The opposite end of the spring is also provided with a hook 31, which engages an eye 32 on the end of a threaded stem 34, which passes loosely through an angular bracket 33 on the adjacent bracket plate, and is engaged by a nut 35, to secure the stem in place, and to permit adjustment of the spring.

The telescoping bar before mentioned, consists of the outer sect-ion 23, and an inner section 36, to whose free end is connected a cross bar 37, which has at each end a vertical lug 38, provided with a bayonet slot 39.

The chair consists of a seat 40, supported by legs 41, which are braced by cross bars 42, and the seat is provided at its rear corners with lugs 43, to which are pivoted the f side bars 44 of the back. The said side bars are longitudinally slotted, at their lower ends, and a plate 45, is secured in the slot, and the plates and legs are provided with registering openings, through which pass the pivot pins 46. The lower face of the seat, adjacent to each side bar, is recessed as at 50, and a plate spring 51, is secured in each recess by screws 52,.the free end of the spring extending beneath the lower end of the plate 45, before mentioned, and the said plate is provided with an enlarged lower end, having two fiat faces 53 and 54, which rest against-the plate, the face 53 when the back is erect and the face 54 when the back is folded. It will be evident, that the construction provides a means for locking the back in both erect and folded positions. The ends of the rear legs are provided with rollers or casters 47, and each front leg is provided with a foot 4" and on its inner face, and near its lower end, with a plate 48, which is fitted upon and secured to the leg, and each of the plates is provided with an angular hook 49, for engaging the bayonet slot 39 of the adjacent lug 38, the chair swinging on the said hooks.

The operation of the device is extremely simple, and is as follows: hen the chair is in the position shown at the right of Fig. 1, that is in folded position, and it is desired to unfold the same, the seat is grasped, and pulled outward. This swings the telescoping bar on the bolt 19, to bring the said bar into the horizontal position shown at the left of Fig. 1, and at the same time the chair swings on the hooks 49, into the position shown in the same figure. The back is now elevated, and the weight of the chair holds it in such position. To fold the chair beneath the table, the process is re versed, the back being first folded, and the chair being tilted backward, when the spring 30 will draw the parts into the folded position shown at the right of the same figure. The foot 457 of the front legs, is of felt or like soft material, to permit the chair to fold noiselessly, and to prevent the marring of the table, by the engagement of the foot therewith.

It will be evident that the table may be provided with an indefinite number of chairs, from one to as many as may be desired, and each chair is entirely independent of all the others. The entire mechanism of the chair may be removed from the table, by loosening the wing nuts 8, and swinging the plates out of engagement with the undercut notches. The chairs are shown as arranged in pairs, and it is evident thatthe supporting bar or bracket may be secured to any suitable support, not necessarily a table, which is shown merely for convenience. It is also evident that by slight modification of the arm 11, three chairs might be supported thereby, and with no modifications whatever, four chairs could be connected therewith, one on each face of the said support. lVith small tables designed for four persons this would be the preferable arrangement.

It will be evident from an inspection of Fig. 1, that when folded, the chairs are entirely supported by the table, and do not touch the floor at any point, and that there is sufiicient clearance beneath the lowest part of the chairs and the floor, to permit the use of a carpet sweeper or a like device, without interfering with the chairs.

The improved chair is especially adapted for use at telephone tables dining tables and writing desks, and may be made in any suitable style, or of any suitable and desired material. In folding the chair, it is rolled inwardly, on the rollers 47 while the front is tilted, and since there is no lifting of the chair, required to fold or unfold, it may be made of heavy material, without becoming unwieldy. It will also be evident from Fig. 1 that the spring does not act on the telescoping bar as long as it is in the position shown at the left, except in the direction of the length of the link, and will not commence to exert a swinging action until the hanger is moved out of a true vertical position. This is due to the bent end of the link, and its connections with the hanger instead of to the bar.

By means of the telescoping arm, the chair may be adjusted toward and from the table to suit the user, and usually in folding the chair the arm is contracted before commencing the folding operation, the chair thus occupying less space under the table.
