' CHAIR-SUPPORTING rRUoK.

Patented June 13, 1916.

Application filed August 16, 1915. Serial No. 45,779.

I To all whom it may concern:

Be it known that I, WILLIAM R. PRIEST, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Chair-Supporting Trucks, of which the following is a specification.

My invention relates to improvements in chair supporting trucks, the object of the invention being to provide a truck which is especially adapted for the support of a rocking chair, so that an invalid can be readily moved from place to place,ieither by pushing the chair or pulling the same by means of a handle,'the latter operating as a tray support when at rest.

A further object is to provide an improved truck of the character stated which can be adjusted so as to fit any ordinary rocking chair, which will be of extremely simple inexpensive construction, which will be strong and durable, and which most efiiciently performs the functions. for which it dotted lines.

is intended. j I With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements ofv parts as will be morehfully hereinafter described and pointed out in the claims.

In the accompanying dra'w'ings: Figure I l is a view in side elevation illustrating my improvements. Fig. 2 isa view in front elevation with the chair andtable removed, the rockers of the chair being shown in Fig. 3' is a sectional plan view. Fig.4.- is an enlarged fragmentary View in longitudinal section through one of the rocker supporting bearing brackets. Fig. 5 is a detail view illustrating the pivotal mounting of the handle, and. Fig. 6

is a fragmentary view in section illustrating the table and its supporting handle bar.

My improved chair supporting truck comprises two parallel axles 1 and 2, to which a U-shaped frame 3 is secured, said frame preferably comprising a casting having recesses to receive the shafts and secured by rivets 4 or otherwise to the shafts. The shafts 1 and 2 are supported in bearing brackets 5, one of which is shown in section in Fig. 4. Each'bearing bracket 5 has 'alined bearings 6 and 7 spaced apart and connected by an arch 8, which extends over the wheel 9 mounted to turn on the axle. The innerbearin 7 is provided with a set screw 10,'which ams against the axle and permits the adjustment of the bearing bracket 6 has a smooth or flat upper face 11 to recelveand support the rocker 12 of an ordinary chair 13,and an upwardly projecting lug 14 on the extreme outer-end of to support the frame and the chair, and

permitthe latter'to be readily moved from placeto place:

When a chair is in position on the truck, the natural curve of the rockers compel the bearing'brackets to assume an angle. relative to thefioor, andthe lugs 14: are preferably rounded on their inner faces as clearly shown. in. Fig. 3, so as to readily accommodate the brackets to the shape of the rocker, and yet snugly hold the same.

It will be noted that when'the-rockers arein place, if the bearingbrack'etsare-ad- I {justed outwardlyas far as possible, 'or,in-

wardly as far ffas possible, the lroc'kers will be securelyjgripped, and there can be'no possibility of acci'dentalldisplacement.

At thev front of the frame '3, upwardly projecting parallel ears, 15 arejpro'vided, andpsupport ahandle 16which is pivotally connectedto the ears by a bolt or rivet 17, and the lower end of said handle16 is beveled as'shownat 18 to engage a beveledblock 19 and limit theinward pivotal movement bracket as desired. The outer bearing,

the bearing 6 acts toconfine the rocker bev of the handle. The upper end of thehandle curves inwardly, and is normally horizontal, and at its extreme end is provided with a horizontal handle bar 20 "which is adapted to support a table 21. 'Thistable v l V 1,186,940

7 21 is removably connected tothe handle,

and while of course I am not limited to the particular manner of connecting the same than push it, the table 21*can 'beremoved' and thelhandle swung downwardly as inl to thehandle, Ihave-sh0wn'1ugs22 0n the bottom of the table which project through openings 23 in the handle 20;

I It will benoted that with-my improveitmentsthe chair can be readily moved about by pushing upon the back of'thecha'ir soas to move an invalid about the roomwori along the streetlas desired'; 1 p a a g If it is desired to pull the chair rather dicated in dotted lines in Fig. 4, and by gripping the handlebar 21, the chair can be pulled whereverdesired.

At the forward end" of the'frame 3, a cross bar24 is 1 located, and constitutes a foot rest, although the other forms of foot rest may be provided as'desired,

P My improved truck is "adapted for use cwith any ordinary rocking chair, and can A 'be furnished-at a reasonably low price, so "that an invalid chair can be made with but slight expense.

- Various slight'changes might be made in the generalform'and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth','but consider myself at liberty to make suchbhanges and alterations as 'fai'rlygfall within the spirit "andsc'ope of the appended claims. 35

Having thus described my invention, what I claim as newand desire to secure by LettersPatent is: i i
