I Toalla/7mm` may conc'cm': l' d Be Ait known that I, HARRY E. GLAD1sn, 'a

citi'zenof the United satatesesiding at Hig- Uinsville, in thecounty "of Lafayette" and l tate of Missouri have invented new anduseful Improvements in Motor Chairs, off

which the following is a specification. y The. object of myfsald invention 'is' the provision'of, a simple, comfortable easilyl controlled and easily steeredfmotor .chair designed more especially 4folrthe'use yf inn valids and convalescents. l

To the attaif ent oftheforegoing,"'the invention consists fin, the improvement as hereinafter described and definitely claimed. In the accompanying drawings, n forming part of thisfspecilication i l Figure .1 isa side Yelevationof themotorv chair constituting. the best practical embodiment'of my invention thatIv hlavefaslyet de? Figure 2 isy a rear elevation yof the lsame, Figure 3isfa front elevation of the chair. Figure 4 is a horizontal sectionl through the chairon the line ofjFigure"1. l y, 'Figure 5 isy a ydetail Ihorizontal section on the line .5 5 ofFigure .Y x Y Figurey 6 is a detailf"fraginentaryl` plan, partly in section, showing Athe"vdriviiig' con nection. f

Similarl l numerals y efreferen'ce designate corresponding Vparts in all ofY thewiew's of the drawings. v1, ff The chair body may be vofa'ny app'ropriate' construction though 4.Ipirefer tofhave' it comprise a seat 1, a back 2, side arms'3, adjust; ment straps 4, anda foot ,rest 5., gThe-.rear portionof the seat` 1v is superimposed 4upon and connectedtoy a loolster,l Figure 2,`and the "said bolster, in turn, is superimposed upon and connected to` longitudinal elliptical springs?, arranged. in' parallel.` .Avrear axle yhousing 8 supports the springs Tand contains yaxlel sections Qfandfan equalizing, gearing 10, Figure thesaid axle `"sectirms 9 being equipped in conventi-2Enl ymanner with drive wheels; 1v1. n ,Il

Appropriately connected to Iand extending forwardly from the ',hou'sing8l isthey frame 12 of the chairwhich frame'lfis provided at its forward end with a cross loar13t h lv which The said crossbar 13 is'vr disposed ahorizorrtal4 plane considerably belowthat of the major horizontal, portion of the;lffrafme'v 12 HARRY GRADISH, o-F HIGGINSVLLR, MISSOURI.

i are pivotallygconne'ctedknuckles v124, Figures i ,3 and`4',bea r1ng forward, steering wheels 15,

and'isjoined to they said major portion by forward corner uprights 16` which serve through' the medium ofcushioning springs l17:tosupport'rods 18 pendent fromvthe fr;

It will be' apparent .from the foregoing that the chair body is adequately cushioned at theback and front with va viewto preventingthe transmission of shocks andjars toy the 4occupant and operator of' the chairf y d Carried on Cross-bars 21 comprisedjin the horizontal portion `ofthe frame 12 is an elec- ,tricv motor 22, the armalnirel shaft 23of which is 'connected'througha universal joint 24 with' the `shaft 25 invconnection with, the equalizing gearing; 10. i

Mounted onta platform 26 on theforward portion of the frame d12 is aboX'or casing 27 inwhichpis a storage battery 28. At29 is a hollow post fixed4 tothe frame 12 and'clipped :at 29X or otherwise held to thel seat 1 of the body in such manner as to `permit the body to ymove .up and down relative tothe post, and at 30 isjfa tube car.n

`ried isaidpost V29." Extendingthrough the post fis a steeringshaft 3'1 on thelower exposeden'd of whichis acrank 32, connec'ted through a rod 33 4with the cross-bar 34 interposed 'between and connecting the rearw ardlyedirected` arms of the `knuckles 14. Arranged at andadapted` to Abe turned onthelupper endy ofthe fp ost 29 is ka handle 35'j that is nedlt'oand vis adapted to` turn the'shaft 31 l`aboutits' axis for the steering For the bralingyof the chair l provide `the hand'lever 36 fulcrumed'at 37 on thepost 29, and I alsoprovidedrums 38 fixed tothe wheel s i 11bands 3,9 about said drums and connected at 40 to theghousing 8, a transverse rack shaft 41, journaledv inbearings 42 yon thehousing 8 and havingarms connected 'to the .bands 39and`Lalso having a crank 44,- and aBodenvvirefor othersuitable 'flexible vconnection 45 between the crank =44 Lso and the hand lever 36. Manifestly when the hand lever 36 is moved toward the handle the brake bands 39 will be applied to retard the chair while when the said lever 36 is released the resiliency of, the bands 39 will release the same from their complementary drums 38. Only slight swinging movement of the handle 35 is necessary for the proper steering of the chair, and, therefore, the chair occupant is always able with the band used for steering to take hold of and raise the lever 36 and thereby efficiently brake the chair.

The handle 35 is chambered as designated by 50 in Figure 7, and in the said chamber 50 are terminals 5l and 52, arranged in a normally open electric circuit with the.

motor 22 and the storage battery 28. Fulcrumed on the terminal 51 is a lever-likev conductive switch blade 53, movable into and out of contact with the terminal 52 and pivotally connected to the ends of the said blade 53 and extending loosely through guide apertures in the upper wall 54' of the chamber 50 are finger pieces 55 and 56, preferably dielectric in character. t will be readily apparent that when the occupant and operator of the car desires to stop the propulsion of the same it is simply necessary for him or her to depress the finger piece 55 when the electric circuit andthe functioning` of the motor22 will be interrupted. To start the chair it is merely necessary for the occupant and operatorto depress the finger piece 56 so as to make contact between the-blade 53 andv ythe terminal 50 when the complete circuit will be reestablished and the wheels l1 will be driven by the motor 22, s c

It will be observed that l. have shown the control of the chair in position for operation by the right hand of the chair occupant. Obviously, however, it isfwithin the purview of my` invention to ylocate `the control for left hand operation, and in this connection I would have it understood that I, prefer to so connect the post 29 that it can be readily transferred or shifted from the right hand side of the chair body to the left-hand side thereof, and I also prefer to provide the rod 34 with an auxiliary connection 34X, Figure 5, for the rod 33, and to provide the rock-shaft 41 with an auxiliary crank for the connection of the wire 42,5.

lf have entered into a detailed description of the construction and relative arrangement of the parts embraced 1n the present and preferred embodiment of my invention 1n order to impart a full, clear and exact understanding of the said embodiment. do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts inasmuch as iny the future practice ofthe invention various changes and modfications may be made such as fall within the scope of my invention as defined in my appended claims,

Having described my invention, what l claim and' desire to secure by Letters-Patent, 1s
