Application filed March 9, 1891. Serial No. 384,204- (No model.)

To all whom it may concern.-

Be it known that I, ATHOL B. MACKLIN, of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Revoluble Reclining Oar Chairs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention is to providea car chair, which occupies the least possible floor space, so that no difficulty (comparatively speaking) is experienced in cleaning thelloor of the car, and more room is provided for the disposition of the limbs of passengers and their small personal baggage. My chair is also a great improvement upon the existing chairs of its class because it can be turned within the least possible space, and instead of its being necessary to confine the seat in two positions (necessary to permit it to face the direction in which the car is moving) it can be placed at any desirable angle to the line of motion of the car. It also permits the passen ger to recline in anyposture desirable, from that of'an upright position to that of a horizontal one, providing support for the back and head in the most comfortable manner possible, and also for thelower limbs and feet without the necessity for utilizing the lower part of the structure of the seat in front of it, substantially as hereinafter fully described, and as illustrated in the drawings, in which,-

Figure 1, is a sideelevation of my improved car chair. Fig. 2, is a front elevation thereof showing the connection between the supporting arm and the chair in the right hand side in transverse vertical section. Fig. 3, is a longitudinal vertical section taken centrally through one, of the seats of my improved car chair. Fig. 4,:is a plan view of my turn table base with the seats and their appurtenances removed. Fig. 5 is a plan view ofthe foot-rest to the top of said arm. Fig. 7 is a detail view showingaportion of the car seat frame looking at it from beneath, and Fig.8 is aldetail view showing in section the pivoting devices of the turn table base. Fig. 9is a front view of a seat containing certain of my improvements, the seat at the right hand side being shown in part transverse vertical section, and the connection between the seat and its supporting arm being different from that shown in the I other figures. A

Referringto the drawings, A represents a base or standard, the basalflanges of which have sufficient spread to insure the equilib: rium of the chair, and which are preferably screwed or bolted to the car floor. The supporting surface of this standard consists, preferably, of a centrally located platform a, which has'ari'sing from its center a pivotal post B, which may be perfectly cylindrical, or have a slightly truncated cone shape. Pivoted on this post, and resting. on the platform is a suitable shaped head 0, which has projecting frame (consisting of the head 0, and arms E),

in a position facing either end of thecar,

I provide recesses r, r, in the front and the back of the post B, and then seat a bolt 8 in r a suitable radial opening in the head 0, which shoots into one or the other of the recesses T, when it comes in register therewith, and locks said turn table frame. Bolt 3 has a suitable knob on its outer end which can be readily grasped so as to withdraw it from the recess 7' when it is desired to turn the turn table frame.

The car seats h are arranged close side by side, one being supported upon each' arm E of the rotatable head, and they are so arranged that they normally face both the same way. The seats are connected to the ends of arms E, so as to revolve thereon. To permit which, the plate D, is provided with the central circular opening, and has secured'to its under surface, preferably, concentric with the said opening, the upward outwardly flanged edges of a collar 1. This collar is reduced to a less diameter at a point a short distance down from the plate D, and its lower portion is set upon and surrounds the top of the upturned end a of arm E.

The reducing of the diameter of the collar forms a shoulder c, which provides a seat for the washer b, which latter is bolted or otherwise suitably secured to the end of arm E, and is of such diameter thatits marginal edges rest on said shoulder c and holds it on the standard. This washer is sort of pan-shaped, that is, has its edges turned upward to about the horizontal plane of the under side of the plate D; then outward, and then downward so as to be inelosed within the upper part of the collar above the plane of the shoulder 0 thereof, as shown in Figs. 2 and 3. In order to lock the seat in any position it may be revolved to, I provide a bolt (1, which enters the notches a, located diametrically opposite each other in the downward turned edges of the washer. Bolt (1 reeiproeates radially in a suitable guide-lug e depending down from the plate D, and through a suitable opening made in the upper part of collar d, just above the plane of the shoulder c thereof,and it has its inner end turned upward at about right angles to its length a short distance. It is surrounded by an expansion spring (1 between its bearings, the outer end of which presses against a suitable nut d and the inner end against the outer circumference of said collar, thus keeping the said bolt shot to the limit of its outward movement at all times, and keeping its inner end normally in one of the notches in the edge of the washer b. By pushing this bolt inward its upturned end moves out of the notch a, into the annular space coming between the vertical portion of the flanged edge of the washer, and thus releases the collar d, so that' it and the seat can revolve. lVhen the seat has been turned sufficiently for the bolt to come in radial register with the other notch, the action of spring (Z causes the inner end of the bolt to enter said notch, and thuslocks the seat again.

Secured to and arising from the sides of the plate D, at points diametrically opposite each other, are corresponding vertical frames fif, to the upper end of which are pivotally connected the forward ends of the arms F, F. The rear ends of these arm-rests are, preferably, ourved upward, and are pivotally secured at corresponding points to the side edges of the back G of the car seat.

The lower edge of back G is hinged or pivoted to knuckles secured to and projecting vertically from the rear of the seat frame 9 in such manner, that when reclining, the occupants body, between the rear of the seat cushion h and the lower edge of the back, will have, as near as possible, a continuous support, and so that the rear edge of the seat will not arise above the plane of the natural line of repose.

Seat frame 9 consists, substantially, of an iron border-band conforming to the contours of the seat cushion h, which rests thereon.

Its rear stretch is connected to its front by means of corresponding longitudinal bars II, H, which are parallel to each other and are arranged an equal distance on either side of the transverse center of the seat. These bars are provided with longitudinal dovetailed tenons on their under surfaces, which enter the corresponding dove- tailed grooves 7,7, made with reference thereto in the plate D, thus insuring to said seat a guide for its longitudinal reciprocal movement upon said plate D. The inner vertical sides of these bars H, facing each other, are provided with longitudinal grooves g, g, and the front of the seat frame is provided with a transverse horizontal slot coincident with the distance between where thebars H, are securedthereto.

I represents a U-shaped frame, the parallel arms of which are a suitable distance apart and have tenons g" on their outer surface which enter the grooves g in the inner surfaces of bars II. The free ends of this U- frame point toward the front of the seat and have journaled therein the foot rest J ,which consists, preferably, of a suitable carpeted board having its edges properly bound; is of a width corresponding to the distance between the parallel arms of said U-frame; and of :rlength corresponding to about the length of the seat frame, less about one half the length of the U-frame, the rear half of which when the foot rest is drawn out remains within the frame 9. When drawn out through the slot in the front of frame g, the foot rest is inclined downward at a suitable angle to afford a suitable rest to the lower limbs. But in order to prevent its inclining at too steep an incline, I pivot link to the inner surface of .the parallel arms of the U-frame about midway their length, and I slot the remainder of these links longitudinally, and provide lateral studs Z, Z, which project from the sides of the foot rest near its rear end and extend through the said slots thereof. In order to providea heel guard for this foot rest I depress the forward end of the same within its border, and then pivot in the sides of the said border, at points very near the forward end, the heel-guard 0, so that it can be folded against and come within the said depressed area of the contiguous end of the foot rest. When this heel guard, which is merelya plate of the dimensions about as shown, is raised to an angle of about ninety degrees to the plane of the foot rest, it is prevented from coming farther by reason of the construction of the longitudinal edge thereof nearest its pivoted center, substan tially as shown in Fig. 1 of the drawings.

In order to hold the seat at any point de sired within the limits of its reciprocal movement, I provide the under surface of one of the bars H with a series of recesses, into one of which the adjacent end of a bolt K shoots when opposite or in register thereto. This bolt K moves vertically in a suitable vertical passage through plate D immediately under one bar H, and has its lower end jointed to the adjacent end of a lever m, which is fulcrumed at a point nearer its' inner end, and between suitable lugs depending downward from the said plate D. Its outer end terminates immediately under the center of frame A by the hand.. The partof rod L that nor- 'mally lies within the passage in frame f, is

surrounded bya coil expansion spring 0, which exerts a downward pressure upon said rod and keeps the bolt K always pressingupward.

So far as the reclining features of my invention are concerned, the chairs may be connected non-rotatably to the arms E, and in Fig. '9 one of the chairs is shown as being so mounted.

There can in an invention such as I have herein described be a simple modification of parts, and changes of sizes and dimensions, and relative distances between deviceswhich can always be made when manufacturing the same, and I wish to be understood as considering such alterations as coming within the scope of my invention.

From the drawings and the foregoing description it will be seen that my invention consists of a car chair or seat mounted, so as to be capable of rotation, at the end of a short arm which arm is itself rotatable upon' a standard or support. This arrangement and construction of parts gives to the chair or seat capability of adjustment to such an extent that the occupant can face with ease and comfort in practically any direction. order that the arm at the end of which the said chair or seat is supported may be'the better balanced,and at the same time arrange two seats or chairs in a space but little greater-than that ordinarily occupied by a single car of the parlor car style, I extend the arm which carries the chair out on either side of its pivotal support, and mount two chairs thereon, side by side, and one chair or seat on each side of the main support or standard. This last referred to arrangement which is the one illustrated in the drawings, and which is the one which I prefer to use, permits the two chairs to be turned together without disturbing their positions relative to each other, and at the same time permits the occupants to both face in the direction the car is moving, or in the opposite direction, or so as to face the windows, or the seats across the aisle; or in any other desired direction. On the other hand it also permits the occupants of the two seats or chairs to face,

one in one direction, and the other in the oppossite direction.

What I claim as new is---- 1. The combination, of the single standard A, the head rotatably mounted thereon and provided with the arms E'projecting in opposite directions from the standard, the looking means for securing the head immovably upon the standard, the chairs independently mounted, one on each arm, E, and arranged close side by side and to normally face both the same way, the said seats being independently revoluble on their supports, substantially as set forth.

2. A car seat having the .plate, D, and the rigid side frames, f, rising therefrom, the seat, h, mounted on the said plate between the side frames and adapted to slide forward and back thereon, the back pivoted to the rear edge of theseat, and the arms pivoted to the side frames and to the back, substantially as set forth.

3. A car seat having the plate, D, and the rigid side frames, f, rising therefrom, the seat h, mounted on the said plate between the side frames and adapted to slide forward and back thereon,the means for locking the seat to the plate in the positions to which it may be adj usted, the back pivoted to the rear edge of the seat, and the arms pivoted to the side frames and to the back, substantially as set forth.

4. The combination with a car chair or seat and the support upon which ,it is rotatably mounted, of the flanged collar d secured to the chair and rotatably mounted upon the seat support, the washer b secured to'the seat or chair support, and arranged within the flange of the collar (1, and the locking bolt seated in the collar d and adapted to engage with the ATHOL B. MACKLIN.
