REVOLVING AND SLIDING CHAIR.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed. December 22, 1906, Serial No. 349,135. Renewed September 11, 1908; Serial No. 452,658.

To all whom it may concern:

Be it known that we, ROBERT W. BUTCHER and JOHN L. PERmN, citizens of the United States, residing at Manila, in the Philippine Islands, have invented new and useful Improvements in Revolvin and Sliding Chairs, of which the following 1s a specification.

' This invention relates to chairs and more particularly to that class of chairs designed for use on shipboard.

One of the principal objects of the invention is to provide a revolving and sliding chair which can be used to advantage in seating persons at the dining table or in other places where it is desirable to move the'chair up toward the table or desk.

Much inconvenience has been experienced on shipboard and in other places where chairs are mounted upon pedestals secured to the floor or deck and being thus immovable toward and from the table for the reason that if the pedestal is located too closely to the table, it is difiicult for a passenger to get into the seat, while on the other hand if the pedestal is located at some distance from the 'table considerable inconvenience is experienced owing to the necessity of leaning over to assume a comfortable position next to the table.

One of the objects of our invention is to overcome the inconveniences referred to and to that end we have provided means whereby the chair or seat maybe revolved upon its pedestal and moved toward and from the table either by the person after he has taken his seat or by the waiter at the back of the chair.

The objects and advantages referred to may be attained by means of the construction illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of a chair or seat made in accordance with our invention. Fig. 2 is a horizontal section on the line 2-2, Fig. 1, and showing an underside plan view of the seat. Fig. 3 is a plan View of the upper member of the turn-table. Fig. 4; is a similar View of the lower member thereof. Fi 5 is a detail section on the line 55, of Fig. 3.

Referring to the drawings for a more particular description of our invention, the numeral 1 designates the pedestal upon which the revolvingand sliding seat is mounted. This pedestal may be ofany suitable construction but as shown, comprises a base portion 2 designed to be secured by screws or bolts to the floor or deck and rising from said base is a tubular standard 3 having radially projecting curved flanges or wings 4. Secured to or formed upon said wings 4 isthe lower member 5 of the. turn-table, said member 5 consisting of a fiat ring or annulus provided with peripheral recesses 6, three of such recesses being shown in the drawings but any suitable number may be employed. The upper member 5 of theturn-table consists of a ring or annulus having three inwardly extending lips 7 formed upon flanges bent downward from the member 5, said lips engaging the periphery 8 of the member 5 between the recesses 6 to permit the member 5 to rotate freely on said member 5. The member 5 may be removed from the member 5 by bringing the lips 7 into coincidence with the recesses 6, as will be understood. Formed in theupper member 5 of the turn-table are a number of screw holes 9 upon opposite sides of said member and secured by means or flanges 13 to engage the flanges 13 of the rails 11. The rails 11 are secured to the underside of the seat a by means of screws 12 and a stop 14 upon said rails 11 serves to prevent the rails 11 from being moved .too .far or to permit the removal of the seat when sliding the same outward.

. Pivotally mounted underneath the seat are a pair of operating levers 15, said levers being pivoted at 16 and passed through keepers 17 and provided with suitable han dles 18. A bolt or dog 19 is connected at 20 to each of the levers 15, said bolt passing through a keeper 21 secured under the seat. The ends of the bolts 19 engage the notches 10 in the rail 11 and when the handles 18 are moved-outwardlyagainst the tension of the springs 22, the seat a may be moved outwardly and inwardly toward and from the table, as required.

In order that the seat may be moved by the waiter at the back of the chair a pair of levers 23 pivotally connected at 24 and connected at their outer ends to the levers are provided and mounted in a guideway at the back of the seat is a button 25 connected to the levers 23. The shank 26 extends into' the gateway in the rear of the seat, and a spring 27 bears against the shank 26 to throw the levers 23 and the button 25 outward. The button 25 may be operated by the knee of the waiter.

The operation of our invention may be briefly described as follows: The seat a may be rotated-to bring the front portion of the seat outward away from the table and when the person, sits upon the seat it may be r0- tated to face the table and then it may be slid forward toward the table by means of the handles 18 being actuated to release the bolts 19 from the notches 10 or by means of the push button 25 from behind the chair. It will be understood that the chair can be freely rotated and will be locked against the sliding movement by means of the bolts 19 and the'notches 10 until the handles 18 or the button 25 are moved, when the seat may be moved inward or outward as required.

From the foregoing it will be obvious that our invention is of comparatively simple structure, cannot readily get out of order, is strong and durable, and can be quickly operated to move the person up to and away from the table either by himself or, by a Waiter or person at the back of the chair and that when moved to the desired position the seat is locked in place auto-= departing from the'spirit and scope of our invention. 7

Having thusdescribed the invention, what we claim is: 1

1. In a chair, a pedestal, a turn table member secured thereto and provided with peripheral recesses, a turn table member provided with inwardly extending lips adapted to be brought into coincidence with said recesses to remove the last'mentioned turn table member, guide bars secured to one of said members, a seat, guide bars secured to said seat, whereby the latter may be moved inward and outward upon the pedestal, means for. locking the seat in its adjusted position, levers for actuating the locking means, and a spring seated push button for unlocking said levers.

2. In a revolving and sliding seat, a pair of guide bars upon which the seat may be moved, one of said guide bars being provided with notches, spring actuated pivoted levers carrying bolts to en age said notches, handles upon said levers f or operating said bolts, a turn table member provided with peripheral recesses, a turn table member provided with inwardly extending lips adapted to be brought into coincidence with said recesses to-remove the last mentioned turn table member, one of said turn table members being'carried by the seat and the other being supported upon the pedestal.

In testimony whereof, we aflix our signatures in presence of two Witnesses.
