Specification of Letters Patent.

Patented May 6, 1919.

Application filed August 21, 1915. Serial No. 46,730.

accommodations for four patients lying on stretchers; or two on stretchers and four seated; or eight seated. Another object is to provide supports for stretcher-s which can quickly be converted into seats and hacks for the seats. Another object is to facilitate and simplify the operation of loading and unloading, and to enable two attendants to do it withthe least possible eliort on their part and with the minimum of disturbance of the patients; also to permit lodgment or re moval of any patient without moving or in any way disturbing the other patients. Another object is to enable a surgeon inside to have easy accessto each patient, Whether lying or sitting.

The following general description will render the detailed description more easily understood. Openings are arranged at the sides long enough to admit a stretchersidewise. Supports are provided to carry stretchers into and out of the ambulance body and the stretchers rest upon these supports while in the ambulance. Two forms of support are'provided, one of them slides in and out, and when out is at such a height that two attendants can place a stretcher upon it Without being compelled to assume an awkward or difficult position. When placed upon the support the stretcher is wholly outside of the body. The support with the stretcher on it is slid into or out of the body with but little eifort and without jarring the patient. The other support is carried on parallel links and when in the body is abovethe sliding support leaving ample space to enable an attendant to work on the patient below. This support rocks on the links outward and downward, the links finally coming to rest on stops, the support then being'at the same height as the sliding support. Each support may be moved in or out, with or without a patient, withoutdisturbing the patient on the other support.

The supports are made in the form of trays and the under surfaces are upholstered. The upper support or tray is pivotally attached to a tie bar which connects the upper ends of the links and may be rocked on this pivot and placed in position to act as the back of a seat. The lower tray has folding legs and may be inverted and stood on the legs to form the seat. Two supports are .thus convertible into. an upholstered seat capable of accommodating four or five persons. The sides of the body are hinged at the top and provided with braces enabling them to be held open to different extents. The lower portions of the sides are flexible soas to be rolled up. The trays are providedv with sockets to receive the legs of the stretcherwhich materially adds to the comfort of the patients.

In the accompanying drawings, which are as nearly diagrammatic as is possible,

Figure l is a side elevation of the body of my ambulance, with portions broken away. It is to be understood that my invention confined to the body and that it is not necessary toshowthe running gear.

Fig. 2 is a rear elevation with the inclosing. portions of the back removed.

Fig. 3 is a similar view showing the trays in position to form a seat.

Fig. 4 shows the end of a lower tray, partly in section, withdrawn from the body andcarrying a stretcher.

Fig. 5 shows a portion of a lower tray with a stretcher in place.

Fig. 6is a plan of a portion of a lower tray-and one of the bars which carry it.

Similar numerals refer to like parts in all of the views. y 7

Referring to Fig. 1' it seen that at each end of the floor 25 there is a narrow pocket 26 to receive the lower ends-of'links 27 and 28. Each link 27 is pivoted to the wall of a pocket. Links 28 are secured to theends of rock shafts 29' (see Fig.1) whereby they are compelled to move in unison. The up per end'oi each link 27 is connected to the upper end of a link 28 by a tie-bar 30, and the trays are pivotally attached to these tiebars at 31. The tie bars normally hold the trays level as in Fig. 2 where theright hand tray is in normal position, while the left is in position to receive'a stretcher. the links then resting on blocks 32. The tray 33 is maintained in elevated position by a hook 34 which engages a pin 35 projecting from the tie bar. To convert the tray into a back it is only necessary to swing itup on edge as in Fig. 3, which brings the upholstered side into position for use.

The lower trays, 40, rest upon T bars 4: which are arranged to slide in guides 42 secured to the floor and are kept in place on the bars by plates 43. on the ends ofthe trays confined between pins 4A: projecting from the sides of the bars. 7

The trays, which are all alike, are made with angle iron frames 50 having sheet metal bottoms 51, below which is the upholstery 52. At each side of a tray there are sockets 53 to receive the legs 54: of a stretcher. The lower trays are provided with the plates 43 before mentioned, and folding legs 55. In Fig. 3 the tray is stand-- ing on the legs. The sockets 53 serve the double purpose of keeping the stretcher in place on the tray and of holding the canvas bed taut, thereby dispensing with mechanism usually attached to the stretcher for this latter purpose, which interferes with folding the stretcher when not in use.

I do not wish to be understood to limit my invention to the embodiment herein shown as it is obvious that numerous deviations therefrom are possible. For example, it is not necessary to provide supports on both sides of the body. Again, either the sliding or the rocking form of support may be used alone, and the latter form in particular is susceptible of modification to meet particular requirements. By suitable changes in the position of the stops 32 the support 33 may when projected occupy a position below the level of the wheel top. If in doing this the upper end of link 28 approaches so close to link 27 that there is a tendency for the inner edge of the tray to drop down the links may be connected by toothed sectors and an intermediate gear, as indicated in dotted lines in Fig. 3.' 1n Fig. 2 the links are connected by dotted lines S, representing tension springs by which the weight of the tray and links may be counterbalanced. As the manner of applying these additions would be readily understood by a mechanic. further illustration is deemed unnecessary.

What I claim is'as follows:

1. An ambulance having a tray mounted upon bars which slide in or out of the body, said tray being adapted to carry a stretcher, and having legs whereon it may stand to form a seat. l

2. An ambulance having a tray mounted upon bars which slide into or out of the ambulance body, said tray being adapted to carry a stretcher andhaving legs whereon it may stand to form a seat; and another tray carried by links and thereby enabled to move into or out of the body and carry a stretcher, said tray being so attached to the links as to enable it to be rocked from its stretcher carrying position to a position suitable for a seat back.

3. An ambulance having a pair of links attached to the body thereof, a tie bar connecting said links, a tray, one side of which is adapted to serve as a support for a stretcher, the opposite side being adapted to serve as a back for a seat; means, including a pivot, whereby the tray is attached to and supported by the tie bar, said means maintaining the tray in a horizontal position, ready to receive a stretcher, but permitting it to be rocked on said pivot to a position where its opposite side may be used as a seat back. Y

4. An ambulance having ,two stretcher supports, one above the other, each adapted to be projected therefrom and carry a stretcher in or out while the other is occupied by a patient, means for maintaining the supports in horizontal position while they are moving in and out, and means whereby each support is brought to the same level when projected.

5. An ambulance having two stretcher supports, each adapted to be projected there from and carry a stretcher in or out; and means for converting one of the supports into a seat and the other into a back for said seat.

6. An ambulance having a stretcher sup port arranged to slide in or out of the ambulance, moving transversely with reference to the stretcher it carries,and' having another stretcher support carried on parallel. links, one end of each link being pivotally attached to the support, the other end being pivoted to the ambulance body insuch position that when in the ambulance the support is above the sliding support, and when moved out of the ambulance assumes a position at the height of, the sliding sup port.

7 An ambulance having a stretcher support arranged to slide transversely with reference to the stretcher it supports and carry it in or out of the ambulance, and having another stretcher support carried on parallel links, one end ofeach link being pivotally attached to the ambulance bodv and the other end attached to the support, arranged so that by rocking the links the support may be moved into or out of the ambulance, this support and the stretcher carried by it occupying a position when in theambulance sufiiciently above the sliding support to afford access to the lower patient.

8. An ambulance having a stretcher support carried on two pairs of parallel links, one end of each link being pivotally attached to the ambulance body and the other end attached to the support, arranged so that by rocking the links the support may he moved into or out of the ambulance, with or without a stretcher thereon; and a cross connection between a link of one pair and a link of the other pair, whereby both pairs oil? links are compelled to act in unison.

9. An an'ibulnnco having a stretcher support, each end of which is carried by a pair of parallel links which when the support in normal position are approximately vertical, said links being pivotally attached at the top to the support and at the bottom to the body of the ambulance, so that when they rock on their lower pivots the support is lowered and projected from the body of the ambulance, two of the links being connected by a shaft so that both ends of the support are compelled to move in unison.

10. An ambulance having a stretcher sup port, each end of which'is carried by a pair of parallel links which when the support is in normal position extend upward, said links being pivotally attached at the top to the support and at the bottom to the body of the an'ibulance, so that when they rock on their lower pivots the sunoort is projected from the bodv of the ambulance, two of the links being connected by a shaft so that both ends of the support are compelled to move in unison, said shaft being at a different level from the lower pivots of the other links.
