SPECIFICATION forming part of Letters Patent No. 378,220, dated February 21, 1888.
Application filed October 11, 1887. Serial No. 252,098. (No model.)
To all whom it 'inay concern:
Be it known that we, ELIZABETH DOUGLAS STAPLES, of West New Brighton, in the county ofll ichmond and State of New York,and HUGH E. AsHORilFT, of Goshen, in the county of Orange and State of New York, have invented a new and Improved Hospital Transfer-Bed, of which the following is a full, clear, and exact description.
This invention relates to anovel form of cot or bed, the object of the invention being to provide for the rapid and easy transfer of patients from one cot or bed to another; and to the end named the invention consists, essentially, of an endless carrier belt or mattress that is mounted upon drums or rollers that are journaled in the bed-frame, all as will be hereinafter more fully described, and specifically pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.
Figure 1 is a side view of our improved hospital bed or cot, the parts being represented as they appear when adjusted for ordinary use. Fig. 2 is a similar view, the parts, however, being represented as they appear when adjusted to a position to transfer a patient from one cot to another. Fig. 3 is a crosssectional view taken on line x as of Fig. 1; and Fig. 4 is an enlarged detail sectional plan view, the view being taken on line y y of Fig. 1.
In constructing such a bed or cot as the one illustrated in the drawings above referred to, we provide four end posts, 10, that are connected in any suitable manner, and upon these posts we mount druxns1l,which are journaled in apertures or slots 2, formed in the upper ends of the posts, as illustrated in the drawings; but any other proper means for mounting the rollers might be adopted. Upon the drums 11 we stretch an endless belt of woven wire or canvas or other proper material, such as that shown at 12, and the upper length of this belt 12 we support by spiral springs 13, that are mounted upon cross-slats 14, the upward throw of the springs being, as usual, limited by cords or binding-wires 15. On either side of the main frame of the cot we arrange bars 16, which have downwardly-extendinglegs 17, that are held to the main side bars, 30, of the bed-frame by clips 19. The bars 16 carry small rollers 20, which extend across the bedstead beneath the upper length of the belt 12. The lower links of toggle-levers 21 are pivotally connected to the side bars, 30, of the bed-frame, the upper links of these toggle-levers being pivotally connected to the bars 16. To the central joints of the toggle-levers 21 we connect bars 22,which bars are in turn connected with the ends of a central drum, 24, by links 23, the drum being provided with a le ver arm or handle, 25. The toggle-levers are inversely arranged upon either side of the central drum, so that as the drum is turned by moving its lever-arm in the direction of the arrow shown in connection therewith in Fig. 2 the toggle-levers will be straightened out and the rollers 20 will be brought to bear against the under face of the upper length of the belt or mattress 12, thus raising said belt or mat-tress clear of the springs 13, as is represented in Fig. 2.
In using the cot above described a mattress of ordinary construction is placed upon the upper length of the belt 12, and the side bars, 16, and with them the cross-rollers 20, are lowered to the position in which they are shown in Fig. 1; but when it is desired to inoveapatient from one bed to another the beds are placed end to end and secured together, the lever 25 is thrown to raise the belt 12 above the springs 13, and the crank-arm is applied to one end of the shaft of one of the drums 11, one of said shalt ends being formed to receive said crankarm, as indicated in Fig. 2. As the crankarm is turned, the upper length of the belt 12 of the bed or cot upon which the patient is resting will be advanced toward the J adjacent bed, carrying the mattress forward, and at this time the belt 12 of the bed to which the patient is to be transferred should be advanced at the same rate of speed and in the same direction as that imparted to the belt of 9 the bed from which the patient is to be moved. Having thus fully described our invention, we claim as new and desire to secure by Let ters Patent- 1. The combination, with a bed frame, of
drums supported thereby, a belt supported by the drums, and springs mounted upon crossslats that are supported by the bed-frame and arranged to support the upper length of the belt, substantially as described.
2. The combination, with a bed-frame, of drums supported thereby, an endless belt carried by the drums; side bars loosely connected to the bed-frame, rollers journaled in said side bars, and a means, substantially as described, for raising the side bars, as and for the purpose stated.
3. The combination, with a bed-frame, of rollers or drums supported thereby, a belt supported by the rollers, springs mounted upon I5 slats and arranged to support the upper length of the belt, side bars, 16, provided with downwardly-extending legs 17, clips 19, by which the legs are loosely held to the bed-frame, toggle-levers 21, connected to the bed-frame and 20 to the side bars, 16, a central drum, and connections between said central drum and the toggle-levers, substantially as described.
