HOSPITAL BED' CRANE Fil-ed April 23, 1932 U A oRNEY Patented June 13, 1933 yIUNI*riso STATI-:s PATENT OFFICE FREDERICK scnnlnnoenn," or 4serrant:Grilnv, Nnw YORK Appncatipn' sied April 23,

invention `relates to apparatus `for lifting invalids `or b'edriddenk persons and itsiobject is vtoeprovide a crane ofthis class which-.may be supported on a vbed,will be 5 adapted 5to bedsof diffe-rent lengthsand con# struetions, and by fwhich a person of vbut moderate strengthA may lift a patient of any weight,.and-which also will be `as little as possible in the way of the attendant in at- 10.tending kthe patient.

VInthe drawing, [F ig. 1- is a side elevation, showing the apparatus in operative position on a bed;

Fig. 2 is `aplan thereof; Fig 3 is lan enlarged plan view of the midportions of the four bars of the supporting structure, disconnected with each other;

v Fig. 4:-is an .enlarged side elevation `of theY lowerend yof a bar and its securingmeans; 1Fig. `shows-fa .fragment of such 4lower end with said means removed; l i

YFig. 6 is a section Online 4 4, Fig. 1, with a certain tube v14 also shown in section, and F igs7andl 8are a side elevation and a plan ofia certainjfoldingbeam.i A g In the drawing lisa bed frame, as of an iron bed of the ordinary hospital type. To thebed vframe is attached th'eupporting structure 1 of my apparatus, which structure is arched as seen in side elevation (Fig. 1) and substantially Xshaped as seen in plan (Fig.2)`. Y

Said structure is constructed as follows: 2*2 designates a pair of bars each of which is formed with each end portion thereof preferably straight but so that with one end portion in horizontal position the other end portion will be offset to one side of the aXis of the first-named endportion and project downwardly, the bend in each har being .preferably a. curve; as to one bai" the offsetting of the downwardly projecting portion is `to one side and that of the other to the other side of said axis. Each bar has preferably'a top longitudinal flange 2a at the outer side thereof, as by forming the bars of angle iron. The horizontal end portions of the two bars are secured rigidly to* gether, so that their flanges 2a form a channel 3 open at the top, by tie pieces 4, which .as shown,

1932,. 'serialjna 607,140. i

Vmay be bolted or riveted to them as shown.

Between the= flanges said horizontal portions of the bars are formed with a longitudinal slot 5, andV they lalso have a longitudinal series of holes 6. f

7-7 designates two other such flanged bars formed inthe same manner as the bars 2. The horizontal end portions of these bars lap under the horizontal end portions of the bars 2-2, projecting reversely thereto their flanges 7a lapping outwardly of the anges 2a of the bars 2 2,- and they also have a longitudinal series of holes 9.

Bolts 10 having nuts ll clamp the horizontal ends of the bars 2 2 to those of the bars 7-7; they are received by four of the holes-6 and 9,.depending on the length which the-supporting structure is to have accord ing to the lengthof the bed. I thus have a structure which in plan is formed with several legs-all diverging from a common center and having their en'd portions vdiverted downwardly so that in side elevation said structure is arched; in the preferred form,

there are four legs.

The downwardly diverted end portion or extremity of each leg is provided with a row of notches' 12, here in pairs of which one in each pair is formed in the main web and the other inthe Harige of the bar. Any pair lof these notches, according to the height required for the supporting structure, is to'receive a pin or bolt 13 which loosely penetrates a tube 14 slipped over the leg. This tube is secured to a leg la of the bed by a clamp comprising two clamp members 15, which have curved end portions (Fig. 6) to embrace the tube and the beddeg, and a bolt 16 and wing-nut17 connecting them. There are preferably two tubes, pins and clamps to support the structure l at the head of the bed, as shown in Fi 1.

t 18 is a pin which traverses the slot 5 and rests on the bars 2-2 between their iianges. It carries a hook 19 which.sup 'ports a block-andfall 20 provided with a hook 20a andy whose rope 206 may be tied to the bed to support any load assumed by the block-and-fall. These parts form a lifting tackle.

A lift to immediately support the patient is shown comprising pivoting devices 2l, two U-shaped bails 22 each having its extremities pivoted on the devices 2l and also formedwith loops 23, and a lexiblestretchgage in holes r28 'in the beam and which isr hunglin'the'hook 20a, of thetackle 20. The lift, beam and rod thus form a sling. I do not Wish to be limited to the particularly described bail part of this sling nor 'in fact to the other details thereof, although an importantifeature of the described sling is a beam, as 26, in that as shown such beam makes it possible to support the rwhole length of the patient, attention being called to the bandages or equivalent l29 which may be used with the lift or equivalent (which supports the torso of the patient,'as shown) to support the patients head and legs.

The beamA as Shown may be folded to shorten its length (as in supporting a child). Thus in Figs. 7 and 8 it Vis shown in two sections26w hinged together atf26w so that .the twowsections'may befolded together face to face, there being a hook 26g pivoted on one section anda stud 262 to be engaged by the hook to hold the sections in extended relation, asin these gures.

ASince the 'supporting structure is formed as seen inplan with several legs all diverging from a common center and having their end portions diverted downwardly, sothat said structure asseen in side elevation is arched, said structure has the necessaryA strength for supporting any load required of it and it affords the necessary clearance for a person, as the physician or nurse, serving4 the patient and having occasionto lean ,over Athe bed at either side or the head or foot thereof for any purpose. It is furthermore adjustable at its top mid-portion to suit the length of the bed and also to suit certain variations in Width, to wit, by springing its legs at the head or foot of the hed ltogether or apart; and it is also adjustable up or down by changing each bolt 13 so as to engage the pair of notches 12 at therequired height. There is also adjustability of the tackle and the sling lengthwise of the bed, due to slot 5.

I do not wish to be liniited to the legs of the supporting' structure being each secured specifically to a leg of the bed, although that So much followsthe con-Y i over the framexand having downwardly eX- tending y'legs adjoining legs of the bed frame, each leg of said structure being notched, a' tube receiving the notched portion; of yeach leg 'of'.` said structure, a pin penetrating the tube and engaged in the notch,"and means to clamp each tube vtothe correspondingA leg ofthe bed frame.' L

,2L In combinati'om'with'aibed, a 'supports ing structure comprising two members'leah having one end .portion-over `the bedl'arid channeled and the remaining portion'ffthere= of bifurcated and Ieachbran'ch of therlatter portion L-shaped in cross section and .form-f ing a continuation of the corresponding- L-shaped half cross-section ofthe channeled portion, one channeled portion being lifeceived in the other, and means to securefsaid channeled portions together,`A the branches of each bifurcated portion beingi spread apart and bent downwardly, and means to secure each 'such branch'to the bed. l 3. In combination, witha bed', a support-- ing structure having a channeled#mid-por-y tion over'the bed vand each of itsend pori tions bifurcated and each branch of the latter portion L-shaped kin cross section and forming a continuation of the corresponding L`shaped half cross-section ofsaid` chan"- neled portion, the 'branches of'eachy bifurcated portionbeing spread-apart and' bent downwardly,"'and `'means to secure? each branch to the bed. A In testimony whereof I affix mysignature.
