To all wliom ii 01mg concern:
Be'ihknownthat we, GEORGE F. SIsB'ownR, a' citizen of the United States, residing. at Flushing, New York city, in the county of Queens andSt'ate of New York, and Louis E. Prr'roNI, a subject of the King of' Italy, residing, at the city of New York, in the county of-Queens and State of New York, have invented certain new and useful I'mprovements in HospitahBeds, the following being a full,'clear,. and exact disclosure'of the one form ofour invention which we at present deem preferable. I
For a-dtailed description of the present form of our invention, reference maybe had't o the following specification and to-the accompanying drawings forming. a part thereof, wherein I r Fig. l is aside elevation with the'bed folded,
Fig. 2 is a similar-view with the bed flat Fig; 3a plan View;
Figs. 4-and 5' show details. v
Our invention relates to a'bed designed particularly for hospitals. It. consists in certain arrangements for rendering a bed spring. of the coil'typefoldable, so that it may be turned up under the back of the patient and also under his knees as is often required in hospitals. 'By the coil-type of bed springwe mean that type wherein there are a; series of upright helical springs mounted on an underl' ing frame with-the helicals loosely linked to one another at their tops usually by small horizontal helicals and enclosed alightmarginal'retaining frame. The dif fioultyof" folding or bending such a bed spring has heretofore made'it necessary in practice to use flat wire-fabric mattresses for hospital beds such mattresses being much less comfortable than the. coillspring type We have overcoine this di'l'hculty by constructing the underlying. frame in. sec tionslongitudinally free of'one another-,and making hinged joints inthe upper. marginal frame' atth'e bendingpointss The axis-of each b end is at the hinge joint inthemangin'al" frame, while the lower framezsections are so mounted as to draw away from or approachto one another as: the bending 90c'urs; In this way the upper surface of the spring. is maintained continuous, the: sec+ tions merely standing at different angles'and the relation thereto of the stuffed mattress on top of the spring remains unchanged. The stuffed mattress conforms to the angular position of the said section, and the upright helicals remain at right angles thereto. At the bottom, however, the continuity is broken by gaps between the separated sections, but suchgapsdo not affect the support of the stuiied mattress while the hinged marginal frame prevents the helicals from sagging down sidewise when downward weight is applied to them atan angle when the bed is bent.
Referring to the drawings, A ,.A A are the head, middle and foot sections of the lower bed spring frame. The middle section A isshorter than the other two and the one at the foot shorter than theone at the head of the bed. When the spring is in its normalflat position (see Figs. 2 andL3) A and A are then separated by a short gap, since the bending. draws them apart .(see Fig. 1) while A and A are separated by a wide gap since the bending. will draw them together (see Fig; 1). The upright helicals- B, B,.etc., are'inounted in groups on the respective sections, being seated on cross bars C, C, etc., as shown in Fig 5. Thebars C, C, etc, are flat andrstand-up edgewise beneath 'the'helicals, but at their endslthey are twisted 90 degrees and also bentover so asto lie flaton thetop=ofthe side members of the aforesaid sections (see Figs. 3'and5) and be riveted thereto. The bottom turn of each helical B is passed through holes 29 6? near the upper edge of the cross-bar C. By this means eachhelical is firmly seated on the frame and secured thereto. The linking of the helicals by small horizontal helicals is shown at the lower right. corner of The entire series oflielicals is enclosed by a rectangular marginal frame It having its side rails jointed atS andS and-secured to each one of the outer row of helicals where it makes tangential contact therewith.
The side-rail of the bedstead is shown at D in the form of aninverted channel bar. On each side-rail D the section A has a link mounting by along link F piv oted at f to said section and a short link f pivoted thereto at F. At its outer end link F is pivoted to a box-dog J which has an oscillating bearing on top of rail D by a pin j and on the under side a pawl engaging rack teethj on the rail. The outer end of link f is pivoted to a stud f on the under side of rail D, and the same stud is connected by a parallel link 7 to the link F. It will be perceived from a study of Fig. 1 that when section A is turned up by handle XV from its n rmal horizontal position shown in Fig. 2 to the position it occupies in Fig. 1, it will rotate bodily around the axis of the hinge-joint S in the marginal frame bar. Its lower right hand end will be guided by link f while the parallel link f will draw link F, together with dog J, to the right and the engagement of the dog with the rack teeth will hold the section at any desired elevation such as is shown, for example, in Fig. 1. The helicals B, B on section A wil remain at right angles thereto, although 11163. are inclinedwith respect to rail D. rhe weight of the occupant acting downardly would tend to make the helicals sag down toward the right. Such sagging would tend to produce downward thrust of the section at the marginal frame R to which the helicals are attached but s eh thrust is resisted by the adjoining section of said marginal frame to which it is jointed. Consequently the helicals, when the section A is elevated, act precisely as they do when the section is in its normal horizontal position. It will be obser ed that section A when lifted has been moved away at the bottom from section A so that the gap between the two frame sections is much wider than it was before the lifting.
The middle section A has a different mounting and a different lifting movement. It will be raised, together with sec tion A by lifting up the marginal frame at the joint S That will draw A to the left slightly till projections T on that section ride over stops T on the side rails D. Section A will be guided into the elevated position of Fig. l by short link 9 connect ing it with stud (see Fig. 5) and at the right by the longer link G connecting it with stud h. In this position it will be locked by a bar 9 having a notch on its under side whichengages a pin on lug 9". Section A? will be guided at its left end by a link H connecting it to stud h and locked by the aforesaid stops T in its raised position of Fig. 1. It will be observed that the lifting has drawn sections A and A much closer together than they are in the horizontal position of Fig. 2 and has also increased somewhat the gap between A and A To lower the sections it is, of course, merely necessary to release the aforesaid locks which uphold them, whereupon they will fall back into the horizontal positions shown in Fig. 2.
