To all whom it may concern:
Be it known that I, THOMAS CRAWFORD, a subject of the King of Great Britain and Ireland, residing at Bristol, county of Somerset, in England, have invented a certain new and useful Improved Ambulance- Stretcher Vehicle, of which the following space in storing the vehicles, since thesupports can be secured to the frame ofthe vehicle and the same turned upon end one against the other in tiers, and again, in as sembling or disassembling the parts,no bolts or other fixingelements have to be manually operated or manipulated, the supports alone being handled. a i
To these ends, the frameis mounted. on wheels, preferably twowsideby side .at or about its longitudinal center, I and one, at each end at or about the transverse center, these latter being carried by springs and mountedto enable the trolley to be easily steered or turned. The stretchersupports are preferably constructed on the cantaliver ALB principle and'comprise standards carrying horizontal arms or brackets extending therefrom, and formed either integral therewith ordeta'chabletherefrom. i Sufficient space is a rovided between the tiers of cant'aliver rackets, and conse- .quently between the superimposedstretchers, to allow of the patients on the lower stretchers bein readily placedin position and removed, %ut, if necessary, the bracke'ts can be swungto the longitudinal posi- .tion to allow of thisbeingdone more easily,
and, if desired, the space mentioned may be such as to permit of the patients-being fed or otherwise attended ,to while on the stretchers carriedb the vehicle.
' Thestandards which support the stretcher carrying brackets-areipreferably maintained in" upstanding petitioner the frame by Patented June as, rare; I
sockets positioned on said frame, and in which sockets the standards are seated. Cotter-pins or equivalent means. cooperate with the standards and with the sockets for the purpose of normally precluding rotary movement ofthe standards in the sockets.
The brackets may be formed of steel tubing brazed to the standards, but they can also be made of malleable cast iron or other metal and slid into grooves in castings at-' tached to the standards, or dropped over standards and held in position by cotterpins extending from the standard. Other convenient means for the detachable mounting or erecting of the standards or brackets,
or both, may be used, according to require- H ments or method of construction adopted.
The lower stretchers are supported by rests on the frame, certain of these being advantageously formed integral with the sockets above mentioned.
Two embodiments of the invention are it represented in the accompanying drawings one form being shown in Figures 1 to 3 in side elevation, plan view and end elevation respectivelywhich represent a simple and illustrated in Figs. 4 and 5 of which Fig.
4 is an end elevation and Fig. 5a plan.
To refer firstly to the construction of Figs.
1 to 3 the ambulance vehicle is shown comprising two side frames or runners a, as of similar material secured to the runners by bolts 0, this frame structure being mounted on four wheels viz. two main supporting wheels one at each side provided with pnew hard wood, and two end cross frames 72 of matic tires and mounted on an axle e as ofm:
gas barrel or piping carried by-the side runners at, and two other auxiliary running and steering wheels 7 also provided with resilient tires and each mounted to slide laterally on a spindle 9 within limits determined by stops it on said spindle, and the as by steel Springs 2' encircling the ends of the spindles and secured with interposed spindles being carried in a resilient manner a blocksnj to the underside of the siderun-gw ners a as by screws.
Secured to the upper surface of each of the cross frames 6 at one side thereof,is a socket is for instancev of cast iron hailing formed, integrally therewith 1 a.
/ stretcher rest Z which cooperates with another rest m at the opposite side ofthe frame to support a stretcher, the said latter rest being conveniently of wood and also 5 secured to the cross frame' The said sockets each receives a vertical standard a prefer.-
ably termed "or steel tubing the upper end of'which has attached'the'reto, as'by a'brazedjoint, a horizontal bracket or arm 0 also conveniently of steel tubing, the connection being strengthened if required" by. an inclined 'strutp. The bracket 0 is by p'refer "once as shown bent to produce-stretcher resting surfaces'q and ron its surface.
The ends of the arms have projectlons s to prevent the stretcher slipping fofi sidewise. P
The upper edge of the socket in is :providedwith two notches or depressions -'t and a into either one of which a cotter :pin 'v or equivalent extending from the standard may engage to hold said standard against axial rotation: 'either with the bracket in the position shown in full lines in Fig. 3 --for"-'reoeption "of a stret'cher'orjn the position'shown iribroken lines in Fig. 1 where the brackets are swung inward for conveniencein loadingor unloadingthe lower stretcher. 7
To now refer to the construction-shown 'in Figs. 4: and'5 the frame structure is formed similarly to that above described, but in addition is provided with 'one ad ditional longitudinal runner a and 'a dentral cross irameb The main wheelaxle "e is also here supported by brackets or hangers 6 carried by suitable shackles or the like *and the steering Wheels f are mounted on'short axles :g carried on steel 40 springs 2' depending "from 'woodblo'cks y fixedto the end cross frames. The sockets are in this constructionattached; to the end cross fra'mes'atth'e longitudinal center of the vehicle and have "stretcher rests Z cast on as shown. 'The sides of the sleeve "are slotted asat M to receive a cotter-pin extending through the standard-to hold thelatter against axial rotation. The standards can thus he slipped into and out -of'i-thesocketswith ease and held securely-in the desired position. The said sockets each receive a vertical standard "n preferably formed of solid steel the upper en'dof which has' attached" thereto by brazed joints two horizontal brackets or arms' o rem-edpreferably "of steel tubing,
, the =connections -being strengthened if required by inclinedstrutsjp. The bracketso are" by preference "shaped :as shown, being bent "to produce stretcher i resting forms on their upper surfaces. The'endsofthe arms have proj ections 's to prevent the-stretcher --s'lipping 0 1i sidewise.
'Withthis construction it will be seen that the. brackets and standards can-" be "readily dismounted from the sockets and fixings can be provided on the bed of the trolley transporter to take the standards when dismounted so that a number of vehicles can be stored in a very small space in tiers or on end. It will also be seen by this construction that the re-assemblage oi the parts is side only, and saving of space, time and laboris effected by the detachable nature of the stand'ards'and brackets which permitof them being dismounted without thc'use of" tools.
I do not limit 1I1ySlf to the exact constructlon or arrangement of parts hereinbefore described since the same may be varied "within the limits prescribed the appended claims without departing from the spirit of'the invention.
What I claim asmy invention and desire to secure'by Letters Patent of the United 1. A' stretchervehicle embodying a base frame -mounted on a plurality of wheels, a
