UNITED STATES PATENT OFFICE CHARLES IB. OVERTON, OF VIGOR, VIRGINIA.

CHAIR.

Application filed June s,

This invention relates to self-propelled rolling chairs, and aims to provide a rolling chair of a novel construction wherein the same may be folded into; a small and compact article to facilitate the storing andv A still further object of the invention is to provide a rolling chairwhich may be readily and easily folded to its inoperative and operative positions.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed,- it being understood that I changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a front elevational view of a rolling chair constructed in accordance with the invention and showing the same in its operative position. v

Figure 2 is a front elevational view of the chair showing the same'in a partially folded condition.

Figure 3 is a side elevational view of the chair in its operative position.

Figure 4 is a perspective view illustrating one portion of the chair and showing the axle construction in detail.

Figure 5.is a perspective view illustrating the brake.

Referring to the drawings in detail, the chair includes a pair of side sections 5 and 6 respectively, the side sections being identical in construction and include spaced paral lel hars,7 and 8 respectively, the bars 7 being formed with cut out portions arrange-d adjacent to the'rear. ends thereof, which cut out portions accommodate the axles 9 which are of the stub type, and" provided with upwardly extended portions 10 that are formed with openings to accommodate the bolts 11 that pass through the upper bars 8.

At the rear of the bars 7 and 8 are vertical bars '12 to which the bars 7 and 8 are secured, as by means of the straps 13, so

1926. Serial No. 114,495.

that the bars 7 and 8 are held in spaced relation with each other. i i

The forward ends of the bars 7 and 8 of each frame are connected by means of the bars 14 that have their lower ends extended below the'bars 7, where they are provided with suitable sockets for the reception of the vertical shafts 15 thatare provided with I forks 16 and in which theufront or small wheels 17 are mounted.

Secured tothe under surfaces of the bars e 7 arev rearwardly extended inclined barsf18 that h ave their rear ends spaced ,from the surface over which the rolling chair is moving, so that should the chair tilt rearwardly these bars 18 will act to stop such rearward tilting. In order to cushion'the movement of the bars 18, springs 19 are provided and disposed between the bars? and 18 as clearly shown by Figure 4 of the drawings.

At the rear end. of each bar 8 is a metallic strap 20 that has an upwardly extending end portion 21 adapted to'engage one edge of the vertical arm 22,, there being provided bolt openingsin the members 21 and 22' for the reception of bolts to secure the arm 22 in position with respect to its supporting member. f p v Atthe upper ends-of the arms 22 are bifurcated members 23 adapted to grasp the ends of the upper bar 24 of the seat back 25 so that the upper portion of the seat back will be securely held against movement.

Bars 26 form the side bars of-the seat back 25 and have their lower ends reduced as at 27 and providing pins adapted to be positioned within. the keepers 28 that are secured to the rear edge of the seat portion 29.;

This seat, portion 28 is formed with of the side frames of the rolling chair. 1

Thus it will be seenthat ,due to this con struction, the seat and seat back act to hold the side frames in proper spaced relation with each other when thechair is in its operative position. 1

Brace bars 31 are employed at the front and'rear of the chair and have] their outer ends pivotally connected to the side frames of the chair, as clearly'shown by Figures 1 and 20f the drawings, the brace bars being arranged in pairs and pivotally connected at 32. These brace bars act 'to' prevent spreading of the framesection when the chair is in its operative condition, while the seat and back sections act to prevent the sections from movingtowar'ds each other.

The arms of the chair are indicated at 33 and have their rear ends connected with the arms 22, the forward ends being con-- nected with the upper ends of the bars 34. that are secured to each frame of the chair.

The wheels that supportthe chair are indicated by the reference character 35 and are mounted on the axles 9 as shown by the drawings. Operating frames indicated at 36 include pairs of bars formed with out wardly curved portions defining forks 37,.

the lowerends of the forksbeing formed with openings to permit the forks to be slid onto the axles 9 to connect the operating framesto the axles.

One of the bars of each frameSo extends inwardly and upwardly providing a. cleargated openings 44 to accommodate the bolt 45 that also passes through the arms 33. Thus it will be seen that by lengthening the chain connectingsprockets 42 and 43, the bearing member 39 may be moved upwardly. The foot rest of the chair is in;-

dicated by the reference character &6 and is supported by means of the downwardly extended bars t? that are pivotally con nected to the frames at 48, and al o have pivotal connection with the foot rest 46 at 49 so that the bars l? may be moved towards each other when the rolling-chair is to be moved to its folded position. The foot rest is also braced against rearward movement by means of the bar 50 that is shown in Figure 3-as extending rearwardly where it connects with the axle, the forward end be ing connected with the foot rest 46.

A brake rod indicated at 51 is shown as supported adjacent to one of the arms 33 and has swivel connection with arm 52 which is pivotally supported by means of the pivot pin 52, and on which the shoe 53'is mounted to engage the wheel 35 associated there with when the handle 54 at the upper end of the rod 51 is forced downwardly, thereby braking the wheel 35.

A lever 56 is shown as formed with a curved end 57 d-enninga shoe mounted ad jacent to and designed to engage the wheel' at the oppositefside of the chair. This leyer 56 connects with the brake rod 51 through the link 58 and-laterally extended arm 59, there being provided a coiled spring 60 connected with the arm 59 to return the arm 59 to its initial position after it has been actuated. Thus when it is desired to operate the brake 57, the rod is rotated by means of the handle 54.

When it is desired to brake both wheels simultaneously, the rod 51 is forced down wardly and rotated at the same time.

From the foregoing it will be seen that to fold the chair, it is only necessary to remove the seat and seat back from their positions between the side frames of the chair, and remove the lower bracing bars 31 at their points of connection with the side frame, whereupon the side framesniay be moved towards each other and the device folded into a small and co npact'article.

I claim: p I 1. A folding rolling chair including side frame sections, means for pivotally connect-- ing the sections, a seat. and seat back removabiy connected, said seatand seat back being supported by the frames and adapted to hold the frames in spaced relation with each other, and wheels for supporting the frames. 7

2. A folding rolling chair including frames, each of said frames embodying parallel upper and lower bars,'means for holding the bars in spaced relation with each other, means for pivotally connecting the frames, and a removable seat and seat back arranged between the frames and sup ported thereby.

3. A folding rolling chair including frames, said frames being wheel-supported, pivoted bars for connecting the front and rear ends of the frames, a seat section adapted to be positioned on the frames, said seat sections having keepers on its rear edge, a

seat back having reduced portions adapted to extend into the keepers, to hold the seat back to the seat, and means for securing the seat back against movement at its upper end.

i. A folding rolling chair including frames, means for pivotally connecting the frames to permi the frames to be moved towards and away from each other, each of said frames includmg a rear upwardly :rtendcd arm, said arm having bifurcated end portions,a seat positioned on the frames, I

a seat back removably connected with the seat and having the upper portion thereof arranged betweenthefurcations of the bi furcated portions of the arms, and wheels for supporting the frames.

In testimony that Iclaim the foregoing as my own, I have hereto'aliixed' my signature.
