Application filed December 7. 1903. Renewed October 26, 19 05. 'Seria1No. '284,467' I To all whzm it may concern I, Beit'known that LIDA W. SCHMIDT, a citi-- zen of the United States, residing in the city,

' county, and State of New York, have invented an Improved Invalid-Chair and-Tractor There;- for; and 1 do hereby declare the following to be a full, clear, and exact description of the invention,'such as wi-ll enable others'skilled in the art to-which it appertains to make anduse. the same, reference being had tothe accomk panying drawings, and to characters of,reference marked thereon, which form a part of this specification. I v v The-object of this invention i's'tocombine a,

wheel-chair. and a tractor-for, drivin'g'the same" in such manner that the chair maybe either materially increased. 1 Thus the chair can be" used-with thetractor or be detachedtherefrom, so as to be used. alone;- By providing the chairwith a tractor detachable at 'wil'l the practical range'of movement of the vehicle is either pushed about by an attendant within the more-or less limiteda'rea of movement of the ordinary invalid-chair or used-for touring.

' such manner as to render the chair capable of standing the deteriorating effects of road use, while retaining in appearance, lightness, &c.,. its adaptability for' use asan ordinary invalidchair.

trated in the accompanying drawings, where- 1n Figure 1 is a view'in side elevation thereof,

the chair and tractor being assembled so as to use the chair for touring. Fig. 2 is a view,-

partly" in section and partly in side elevation,- of the chairas used when pushed-about by 'an' attendant; and Figs.- 3, 4, 5,;a'nd 6 are detail views of certain portions of the chair.

The body of the chair comprises as its es sential features a seat'a, side bars 6, arms 0,

and back (1, pivotally associated together and 1 with the seat a in such manner as to 'be ad a ustable to various positions (see the dotted two tubular side bars h, each carrying at its lower end a tubular T- i, made rigid with the rear portion of the seat a brace 7'. In the My "invention vWin be found fully illus' the parts :0 afford.

horizontal portion of. each T, "which is made as a clamp is, is adjustably arranged a tubulart barZ, the two.'bars'.Z being connected byah ,inverted-U-shaped tubular portion m. (See Fig. At its middle portion the frame thus formed-by tubes Z and m carries a bracket'n,

whichat 0 forms a vertical hollow bearing for" I the spindle of a fork p, in which is journaled a steering-wheel q', the spindle being held in placeyby amilled nut 7' and carrying a steering-handle s. I By removing nut rthe ste'ering device comprisedin parts 9, q, and sway be removed. Byrnanipulating clamp kit may 5 be seen that the frame comprising parts Z and m may be adjusted forward and back.

I {designates the main. axle, and u. the main wheels fixed thereon. The. springs 'v of the chair are sustained by bracketsw, (see Fig. 5,).

carried by the axle and one of which is bolted to each spring.

tained on the springs, the same being bolted to the springs and having slotted flanges y,

. "through which extend. threaded studs 2, pro'- In carrying out my inventionI preferably employ a'chair of the type of that illustrated inmy copending'application, Serial-No. 148,491,

and combine it with some suitable tractor in jecting from a plate 1 on the under side of the seat a, said studs carrying wing-nuts 2 for (See Fig. 6.). The; adjustment thusafforded makes: it possible .to shift the chair bodily backward,'soasto bring its centerof gravity noticed" that at this time it has no other sup-- port (the steering-wheel q being removed) than 3 is a handle-pivoted at 4 to the back not the Ia-denotes brackets whereby the seat a is suscla'mping the, plate 1 firmly to the brackets w.

,as'much as possible-over the axle while the a chair, is beingvused'with the tractor, it-being chair, so that it. may be eitherused by' an attend'antto push the chair about (at which time it is held-horizontailyby a wing-nut 5) or folded'dowmas when the chair is being used; with the tractor. y The bracketsvw carry atubular bar 6, ar

ranged parallel-with the axle t and carrying centrally another bracket 7, formed with alined bearings 8 .In these bearings .is journaled, by means of a suitable bolt 9, a T 10, in which] the forward ends of horizontal'- side bars 11 of thejrame of the tractor are secured; These side bars carry uprightsl2 and 13, the latter bent at' andncline rearwardly', thus bringing the center of gravity of the seat 14, which said uprights carry, approximately over the naled in the uprights'13.

"es of which stand vertical for a portion of'their length up from the sidebars and Tare-then The motor'is indicated t 16,- it ha gaelectric motor of any suitable type. 17 is the storage battery from which the source of power for drivingthe motor is taken,

the same being sustained on a support 1 8,secured to the uprights 12 and 13. 19 represents suitable electrical connections between the battery and the motor, and 20 is a controller of any suitable type.

21 is a bandbrake engaging the periphery of a disk'22, fixed on the axle, the band-brake being worked from a foot-lever 23.

24: is the steering-handle, the same being pivoted to thelbracket 7 in the upper end.

thereof," It will be understood that this handie is attached when the tractor'is being -em' ployed to drive the chair, at which time the steering mechanism comprised in parts 0', q, 0", and s is removed. The vehicle,comprising the chair and the tractor, is thus steered byturning' the chair bodily by, means of thehandie 24 on the bolt'9 as a pivot, v

25 is a foot-rest supported on theside bars 11 of the tractor by means of rests 26.

Having thus 'fully'described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a vehicle, the combination of a wheelchair, a motor or tractor havinga pivotal connectioii therewith and arranged ac of the .same; and a means projecting from the chair on, substantially as described.

3. In a wheel-chair, the combination of the chair'proper, the axle and Wheels, means for supporting the chair on the axle, and a tubular structure arranged in the front lower portion of the chair and adapted to carry a steering-wheel, said structure being adjustable for ward and back in the chair, substantially asdescribed.

I In testi'monythat I claim the-foregoing I have hereunto set my hand this 30th day of October, 1903,

IDA W. SCHMIDT.
