CHAIR-SUPPORTING TRUCK.

Application filed December 16, 1916.

To all whom it may concern Be it. known that we, JENNIE M. Hosion and ADoLrn D. Lownx'rHAL, residents of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Chair- Supporting Trucks, of which the following is a specification.

This invention relates to chair supporting trucks, an object of the invention being to provide a truck upon which a rocking chair may be mounted and an invalid given all the conveniences of the usual high wheeled patients chair.

Another object is to provide an improved truck of the character described which may readily be adjusted to receive any ordinary rocking chair and which when not in use may be compacted to a minimum space for transportation or storage.

A further object is to provide a device of the character described which will be economical in construction, strong and du rable in service and which will eiliciently perform the functions for which it is 1ntended.

lVith the foregoing and other objects in view, the invention consists of the novel construction and arrangement of parts illustrated in the accompanying drawing, which forms a part of this specification, wherein is set forth an embodiment of the invention, but it is to be understood that such changes and modifications may be resorted to as come within the scope or" the appended claims.

In the accompanying drawing wherein like reference characters designate like parts in the several views: Figure 1, is a plan view of an embodiment of the invention, in position for a chair to be placed thereon, and with the foot rest extended: Fig. 2, a section on line 22 of Fig. 1, showing achair rocker in position: Fig. 3, a front elevation, with the foot rest removed: Fig. 4, a top plan View of one of the side bars, with the 'associated portion of the axle turned back parallel therewith, and the wheel removed as for storage or transportation: Fig. 5, a section on line 5-5 of Fig. 3; Fig. 6, an elevation of the brake.

The invention comprises an extensible separable axle 11 which in the embodiment of the invention herewith illustrated comprises two telescopic sections --12 and Specification of Letters Patent.

Serial No. 137,346.

13. A bracket lt is suitably associated with, or connected to each of these sections, near the outer end thereof. As

illustrated these brackets each comprise a floor, or base l5 *ith upstanding side walls, 16. The axles extend through openings l7 in the lower portion of the side walls. A sleeve 18 is disposed about the axle, between the sidewalls, and is secured thereon by suitable means such as pins 19, or by electric welding. In the case of the female section 12 a stud -20 (see Fig. 5) is passed through the side walls and secured in the tube which comprises that section by suitable means such as pins --22, or by electric welding. lVheels 23 are removably mounted on the axles, exterior of the brackets being retained thereon by suitable means such as cotter pins -Q4-. The brackets 14L are pivotally mounted, by means of pivots 25, on plates which in turn are rigidly attached to and extend laterally from side rails -2T. The arrangement being such that the inner side of the bracket is substantially in alinement with the outer side of the bar. The side bars are preferably formed of angle iron, the plates -26 being attached to the upper side of the hori- Zontal members at the forward ends or the bars, while at the rear ends, brackets 28 similar to the brackets 1% are attached to the vertical members, so as to be in alinement with the brackets 14. The brackets are each provided with thumb screws -29- for the purpose or" firmly holding the chair rocker. These thumb screws have swivel heads 30 and are provided with lock nuts -3l. A caster 32 of any suitable design is connected to each or" the brackets -28. A removable foot rest is provided which comprises a platform -85- which is swung by its forward edge to a substantially U shaped frame -36 comprising a transverse member 3T-. and side arms -38. These arms rest upon the axle 11, and are pro ided at their rear ends with lateral projections 89 adapted to be engaged under the side bars. The lower edge of the side bars may be provided with a plurality of spaced notches 40 for the reception of the projections 39. It will be observed that the foot rest may be slid back out of the way, drawn out to any suitable extent or removed com pletely without trouble. With the truck in the position shown in Fig. 1, a rocking chair, the invalids favorite one, is positioned thereon with the rockers in the respective brackets 14 and 28, the axle being telescoped more or less according to the distance between the rockers, which varies with different chairs, the pivotal connection between the axle and the side bars permitting the side bars to be alined with the rockers which slope more or less rearward. The chair may then be given any desired inclination, by sliding the rockers forward, or backward in the brackets, and the thumb screws tightened up to clamp the rocker firmly. A

brake 4c1- is attached to one of the side bars preferably at the rear end thereof where it is in a favorable position to be actuated by the foot of the person moving the chair. This brake is adapted to be brought into touch with the floor and by frictional contact therewith hold the chair stationary. It may be of any suitable construction, that illustrated being one that is widely sold on the market as a door stop. When not in service the foot rest is removed the wheels taken otf, the axle separated and the two portions thereof turned back parallel with the side bars, to which they are connected,

(see Fig. 4). Thus the truck may be compacted to a minimum of space for storage or transportation.

Having thus described our invention so that any one may make and use the same, we claim:

1. In a chair supporting truck, an extensible separable axle, and side bars with which the respective portions of the axle are pivotally associated.

2. In a chair supporting truck, an extensible axle comprising separable parts, side bars with which said parts are pivotally associated and means for mounting a rocking chair thereon.

3. An extensible separable axle, wheels mounted thereon, side bars pivotally connected with said axle, casters carried by said bars and means for mounting a rocking chair upon said axle and bars.

4:. An extensible axle comprising separable parts, a bracket carried by each of said parts near the outer end thereof, side bars with which said brackets are pivotally associated, brackets attached to said side bars and means for securing the rockers of a chair in said brackets.
