ADJUSTABLE SUPPORT FOR BEDS.

To all whom it may concern:

Be it known that 1, WILLIAM J. CURTIS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Adjustable Supports for Beds, of which the following is a specification.

This invention appertains to improvements in bedsteads and particularly to that type known more generally as invalid bedsteads in which adjustable rising sections are employed. 7

The primary object in view in my present device is to provide a specially formed bedstead which in actual use is designedto be entirely hidden by the bedclothes, and embodying a quickly detachable spring having the rising sections hereinbefore mentioned connected therewith, said spring being susceptible of attachment to the ordinary bedstead of this class without any alteration in its essential construction in order to procure the advantages of an adjustable element of this nature to eliminate the necessity of removing the spring from the bedstead in cleansing, as is required in most devices now in use.

Wore specifically speaking, it is comprehended by my invention to provide a bedstead with a spring embodying a central frame section adapted to be attached to the side rails and having connected thereto at opposite ends adjustable sections or sup ports, novel locking mechanism by means of which the supports are held at various inclinations being employed and comprising actuating levers connected at one end to locking levers carried by the supports and which levers are adapted to be depressed by the actuating levers to permit free movement of the cooperating support.

lVith the above and other objects in view, this invention consists in the construction, combination and arrangement of parts all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of a bedstead embodying my invention; Fig. 2 is a top plan view of the same; Fig. 3 is an enlarged fragmentary sectional view taken about on the line 33 of Fig. 2 and showing more clearly the locking mechanism in side elevation; Fig. 4 is an enlarged fragmentary sectional view taken on the line H of Fig.

Specification of Letters Patent.

Application filed December 26, 1913.

1; Fig. 5 is a perspective view of a corner .member for the central frame section; Fig.

6 is a side elevation of an ordinary bed construction with my improved spring attached thereto; and F 7 is a view of the spring in collapsed or folded position.

Throughout the following detail descrip tion, and on the several figures of the drawings, similar parts are referred to by like reference characters.

Specifically describing my invention and referring to the drawings, the bedstead embodying the same comprises the side rails 1 having connected to their extremities the outwardly curving legs 2, the construction of said members being preferably angle iron,

such as is commonly used in articles of this nature. The object of forming the legs 2 as just mentioned will be brought out more clearly in this description hereinafter. Said legs 2 are connected adjacent their lower portions with cross bars 2 while similar longitudinal bars 3 extending beneath in parallel spaced relation to the side rails, connect the legs for strengthening the structure. Upon this frame or bedstead is dis posed the essential feature of the invention consisting of the intermediate stationary spring section 4 and the adjustable head and foot rising sections 5, 5, and both of the last mentioned sections being identical in form the construction of one only will be described. The adjustable section or support 5 comprises a substantially U-shaped frame having the side members 6 which are connected by resilient or spring wires 7 lymg approxlmately 1n the same horizontal. plane as the upper surface of the stationary spring member at. Each of the side members 6 of the support 1S suitably formed with a depending arm 8. The support, furthermore, is pivotally mounted upon the upper portion of a brace member 9, as shown most clearly in Fig. a of the drawings, there being a brace member for each side of the support which is connected to a central frame construction now to be described.

The central frame which constitutes the support for each of the rising sections 5, 5, is rectangular in form and comprises the four corner members or brackets 10, shown in detail in Fig. 5, each having an offstanding lip or flange 11 through which extends a fastening member 11, the two of said brackets on the corresponding sides of the bedstead being connected by longitudinally extending angle bars 11 which are disposed directly beneath the side rails l, which side rails 1 are clamped between the bars 11 and the flanges 11 by the fastening members 11 above referred to. The lower portion of each two of these corner brackets at opposite sides of the bedstead are connected by the transverse bars 8 fastened to an inwardly extending lug formed on each of said brackets and as seen in Fig. 1 a brace member 9 is secured at one end to the transverse bar 3 and its other end on which a side member of the support 5 is pivoted, passes through the adjacent bracket near its topmost portion, being securely fastened in this position. It will thus be seen'that a most rigid subor intermediate frame is formed, to the opposite ends of which are pivotally connected the adjustable rising sections hereinbefore described, and upon the frame is removably disposed the intermediate spring member 4 referred to, a plurality of straps or bars 3 being preferably provided and connecting the longitudinal bars 3 to efiectually support said spring member,

It is to be noted that each of the brackets .10. is formed with a toothed sector 10 directly adjacent the depending arms 8 of the rising sections, in the lower bifurcated terminal of each of which is plvotally secured a locking lever 12 which is curved in forma- I tion and at its free extremity terminates in a slotted enlarged portion 13. The side members 6 of the support 5 are also formed with depending lugs 14 and to each of the same is pivotally connected intermediate its ends a curved actuating lever 15, the inner extremity of which is provided with a laterally projecting pin or projection 16, extending into the slot of its cooperating locking lever 12, thereby providing a pin and slot connection between each actuating lever 15 and locking lever 12. Extending laterally from each of the locking levers 12 is a lug or projection 17 which is adapted to engage with the teeth of the adjacent sector 10 and thereby lock the support against downward movement. Each locking lever 12 is normally held in locked or engaging position with respect to its cooperating sector 10 by means of a spring 18 one end of which is connected to the adjacent side member 6 near its pivot and the other end to the locking lever approximately midway of its length.

To the outer end of each of the actuating levers 15 is secured a flexible connection 19 and to the end portion of the U-shaped sup port 5 and at each side of the same is pivotally secured a lever 20 one end of which is connected with the adjacent flexible connection 19. 'It will be seen by reference to Fig. 2 of the drawings that the levers 20, pivoted intermediate their lengths have their contiguous extremities disposed in superposed relation so as to cooperate with a grooved cam member 21 adapted to be rotated by means of a handle 22 and in the actual use of my invention it is only necessary for the operator to grasp the'support 5 turning the handle 22 so as to actuate the levers 20 through the instrumentality of the cam 21, and thereby cause the actuating levers 5 to depress the locking levers 12, disengaging the projections 17 from their 00- operating toothed sector. When the proper adjustment has been reached thehandle 22 is rotated to its initial position and the springs 18 will then pull their cooperating locking levers upwardly into engagement with the toothed sectors 10". Itwill be noted in Figs. 1 and 8 that the slots in the extremities of the locking levers are inclined downwardly and when the actuating levers 15 are pulled upwardly. at their outer ends,

the pins 16 will slide down the slots to cause preventing any tilting action of the bedat f its end portions, due to the placing of weight upon the adjustable supports which are suspended at these end portions from a point intermediate the side rails, as hereinbefore described. It furthermore permits of ready access to the ends of the bed for the purpose of manipulating the handle for operating the actuating levers to adjust said supports.

As shown most clearly in Fig. a, the longitudinally extending bars 3 are arranged contiguous to the lower portion of the corner members 10 and these bars, one ateach side of the bedstead prevent any oscillation of the spring member as will be apparent.

Fig. 6 of the drawings shows the adaptability of the spring of my invention to the ordinary commercial bedupon. which it may readily be attached without any change of structure. It also illustrates the ease with which the bedstead may be cleaned and kept in sanitary condition by reason of the factthat the supports may be raised upwardly into any position from the horizontal, as shown in this figure. Again, as shown in Fig. 7, the supports may be folded upon the central frame section and spring member into a very compact structure enabling the displacement of the spring from the bedstead withease and also rendering the struc' ture very compact for shipping or similar purposes. 7 I

Having thus described my invention, what is claimed as new is 1.
