INVALID-BED.

Specification of Letters Patent.

Patented Jan. 2, 1906.

This invention relates to improvements inV beds for invalids or bedridden persons, designed vto facilitate attendance upon such persons.

It consists of the features of construction set out in the claims.

In the drawings, Figure 1 is a side elevation of a bed structure embodying our improvements. Fig. 2 is a detail plan view of the structure with mattress removed and 'frame broken away, showing the devices for operating the bed-pan and pad. Fig. 3 is a 'section at the line 3 3 on Fig. 2, showing the mattress and pad in position. Fig. 4 is a detail section at the line 4 4 on Fig. 1. Fig. 5 is a longitudinal vertical section of the bed- Fig. 6 is a bottom plan view of the same. Fig. 7 is a detail section through the bottom portion of the bed-pan and the plate on which it is carried, showing the means of securing the parts together. Fig. 8 is a plan view of the pan-supporting plate. Fig. 9 is a longitudinal section of the pan and carrying-plate in a modified form. Fig. 1() is a transverse section of the same at the line 10 V10 on Fig. 9.

In the structure shown in the drawings the mattress 1,which rests upon a suitable spring support of so-called woven-wire mattress 2, has an aperture 1a registering with a corthe woven-wire spring or mattress, and it is carried and supported by a perforated sheetmetal plate 4. This plate is made longitudinally rigid by any suitable means and is mounted upon the wrists 5fL at the ends of the crank-arms 5b of the crank-shafts 5. These crank-shafts are provided with bearings 6, in which they rock, supported by the side rails 7 of the frame of the bed or woven-wire mat- The aperture 1a in the mattress tress 2. The j ournal-bearings for the crankshaftS, respectively, are at a distance apart on' the side rail 7 equal to the distance between the wrists 5a on the perforated plate 4, said plate constituting a link which connects the crank-wrists holding the crank-arms parallel in the rocking movement of the shafts. The shafts are journaled at such position that when the crank-arms are substantially horizontal the plug 3, resting on the link plate 4, is in position, entering through the apertures 2a and la, to bring the plug into position to close the aperture 1ab of the upper mattress. In order that the plug may be carried and held securely, the rock-shafts are connected by additional parallel lever-arms 9 9 at an oblique angle to the crank-arms 5 5, and these lever-arms 9 9a are connected by linkbars 10 10, pivotedat opposite ends to the lever-arms'9 9a, at equal distances from the two rock-shaft-journal bearings, so that said links 10 are parallel to the side rails 7. The lever-arms 9 are extended down from the pivotal connection of the link 10, preferably, as shown, at anV angle to the preceding eX- tending of the link 10, and to one of these lever-arms 9 there is pivotally connected a ratchet link-bar 11 having a slot 11a, through which passes the pivot-bolt 9C, which connects the lever-arm 9a with the link 10, and at the upper side of the slot the link-bar is provided with ratchet-teeth 11b for engaging the pivot-bolt 90. It will be seen that this structure adapts the ratchet-link 11 to lock the rock-shafts and their connected leverarms in position, upholding the plug 3 in the position shown in Fig. S-that is, closing the aperture in the mattress-and that by releasing the ratchet-bar the plug can be lowered to any distance and locked in any position within the range of the ratchet-notches.

The bed-pan 12 is adapted to be substituted for the plug 3 on the link-plate 4 and is therefore of suitable dimensions to be passed up through the apertures 1L and 2a to bring its IOO upper margin substantially level with the top are adapted to be retained in position on the lIO link plate by means adapted to prevent lateral movement of the plug or pan. The preferred means for this purpose adapted to leave the pan with a flat bottom consists in forming on the plate an upward protrusion, as the upstruck boss 4b, which enters a corresponding recess 14, formed in the bottom of the pan or plug. In the case of the pan this recess may be struck up in the bottom sheet of the pan itself, andin the case of aplug abottom metal sheet 14UL is provided, having the recess 14 similarly struck up in it. For securely locking the plug or pan to the plate the upstruck boss 4b of the plate has a slot 4, and from the bottom of the recess 14 a stud 15 is provided, projecting downward, having at its lower end a turn-button 15, adapted to pass through the slot 4C and to be turned ninety degrees across the same. Another form of means for engaging the pan or plug with the plate so as to prevent lateral movement is shown in Figs. 9 and 10. This means consists of a longitudinal tongue 4C, mounted upon the upper side of the plate 4 and oHset upwardly therefrom, said tongue being adapted to enter a longitudinal pocket 14X, formed on the bottom of the pan and on the bottom of th bottom plate 14a of the plug. Preferably, in order to cause the pan to stand steady notwithstanding the longitudinal upraise formed on the bottom by the longitudinal pocket, two longitudinal ribs 14y 14y are also formed on the bottom plate of the pan or plug. In this form of the device it is desirable to provide a stopl for the pan and the plug when they are thrust onto the tongue, and for this purpose the plate 4 has a stop 4", in which there is an adjustable clamp 4*', against which the end of the pocket is stopped.

For causing the mattress to retain its proper position on the woven-wire spring with the aperture 1a properly registered with the aperture 2a I provide corner-posts 16, projecting upward from the woven-wire mattress at the corners of the aperture therein, which, entering the aperture in the mattress and engaging it at the corners, prevent the mattress from slipping up or down or cross- Wise, as it is liable to do in the movements of the patient. These posts are conveniently made each of asingle piece of wire folded upon itself at the middle point, as may be understood from Figs. 2 and 3, to form the upstanding terminal, the two ends being bent out horizontally at right angles to each other (see Fig. 2) above the woven-wire fabric and secured firmly thereto by staples 16a, passing through the woven wire and through a baseplate 16b,lodged under the woven wire into which the staples are riveted, clamping the woven-wire fabric between the wire terminal 16a and said plate.

For conveniently mounting the crankshafts 5 on the side rail 7 and for securing to these crank-shafts the lever-

arms

9 and 9,

above described, fittings are made in the form seen in Fig. 2 and shown in section in Fig. 4. The fitting 6, havinglugs 6a for bolting it to the horizontal flange of the side rail, constitutes the journal-bearing ofthe rockshaft and projects inward far enough to clear the horizontal ilange of the side rail. The fitting 18 is bored for the rock-shaft and keyed fast thereto by the cross-pin 19, (see Fig. 4,) and it has the lug 20,formed to seat the lever-arm 9 or 9u, which is secured in its seat in said lug by a single bolt 21, one bolt being sufficient to render rigid because of the lateral flanges 20a, between which the bearing is lodged in the lug.
