BED.

Application filed September 25, 1924. Serial No. 739,754.

My invention, relates to beds. An object of my invention is to provide a bed which will furnish the maximum amount of comfort to the occupant thereof, especially where the condition of his health requires that, a large amount ofhis time be spent in rest.

It is a further object of my invention to provide a bed of such nature that a bedpan may be placed under a patient and removed therefrom after use without any discomfort or soiling of the bedclothes, and without liability of injury to a patient who may have undergone a serious operation, where to move certain parts of the body would be harmful or even dangerous.

It is a further object to provide means whereby a person convalescing from a long illness may be permitted to be raised to any desired angle; hence a patient may be permitted, having been suffering from a long illness, to accustom himself gradually to sitting up, without the annoyance of having to be propped up with pillows.

Further objects and uses of my invention will suggest themselves to those skilled in the art, from the accompanying drawings and description. As one use of my invention is as a cot for hospitals, sanitariums or like institutions the foregoing discussion will be carried on with especial reference thereto,

but it is understood that I am by no means limiting myself to such use by this specific reference to it.

In the drawings:

Fig. 1 is a side view of my improved bed, with some parts broken away, showing the auxiliary frame in normal position.

Fig. 2 is a side view'showmg the auxiliary frame in raised position and the head and foot sections partly raised.

Fig. 3 is a fragmentary plan view, parts broken away, of the lower portion auxiliary frame, showing the interrelation of the mechanisms for raising the head and feet.

Fig. 4 is a plan view partly in section of the front portion of the frame showing the interrelation of the parts.

Fig. 5 is a plan of the top portion of the frame, parts broken away.

Fig. 6 is a section on the line 66 of Figure 2.

Referring more particularly to Figs. 1 and 2, 1 represents the headboard of a bed made according to my invention; 2 represents the footboard, and 3 the spring frame upon may lie thereon, is secured to the portion 6 at 8, substantially in the middle of the bed by being riveted thereto. The canvas or other material may be slit here for the convenl'ence of a patient occupying the bed. Pivoted to the section 8 at 9 is a head andtrunk rest portion 10. To the other end of section 8 is pivoted at 11 thethigh rest portion 12. This is in turn connected bytoggle 13 toleg rest portion 14.

The support 5 rests onracks 15 placed at each corner of the bed. These racks engageinions 16 mounted onlatitudinal shafts 17.

rackets 18 mounted on the head and foot of the bed act as a bearing for theshafts 17. At the right of these shafts are mountedworm wheels 19 which engage withworms 20 mounted onshafts 21 extending longitudinally of the bed and supported bybrackets 22.

Ashaft 23 extends latitudinally of the bed near the head thereof and underneath frame 7.- This shaft turns in brackets 24 and is broken to permit the passage oflongitudinal shaft 25 between its parts. Mounted on this shaft are twoparallel gears 26 and 27 arranged so as to mesh withgear 28 mounted onsleeve screw 29, which in turn is rotatably mounted onshaft 25 in such a way that each may rotate freely and independently of the other. Thegears 26, 27 and 28 are held together by collar '30 fastened toshaft 23 byscrew 31 and firmly held by a piece ofmetal 32.

Trunnionnuts 33 adapted to slide along the threaded portion ofsleeve screw 29 act as pivots for a slidingarm 34 which carries at its further end aroller 35 adapted to support thehead rest portion 10.

Asecond roller 36 supported bybracket 37 is placed at the end of thesleeve screw 29 towards the foot of the bed. This roller acts as a support for thearm 34 and-as an aid to the raising of theroller 35.

Placed above and to the right of theshaft 23 is a secondlatitudinal shaft 38 which engagesspiral gear 39 which in turn engages slidable ontrunnions 43 inslot 44. Thisbracket 42 is pivoted to theleg portion 14 and its motion along the threadedportion 41 regulates the raising of theportions 12 and 14 by action of thetoggle 13.

Between the toothed racks 15 and the head and foot of the bed areguide rails 45 on which slide guides 46 which keep the parts of the frame 5 in alignment and en sure that all portions of the frame 5 or of any section thereof will he raised an equal amountwhen it is desired to adjust it.

Thelongitudinal shaft 25 is duplicated on the opposite side of the bed, together with the mechanism it carries and thelatitudinal shaft 17 is also duplicated at the foot of the bed. The racks l5,pinions 16,guide rails 45 and guides 46 are found at all four corners of the bed.

The 0 ration of the bed is as follows: When t e attendant desires to raise the patient off the mattress he inserts a crank onto the end ofshaft 21 the end of which is s uared to receive the same and turns in one direction. This brings therack 18 into motion through its engagement with worm wheel 19-andworm 20 and may be done from any corner of the bed. The guides 46 sliding alongguide rails 45 serve to keep all parts of the frame 5 in alignment so the part 5 will be raised an equal distance throughout. The distance the frame is raised is, as will be seen, regulated by turning the crank through a greater or a less are. To lower the frame the crank is turned in the opposite direction.

To raise thehead portion 10, the crank is inserted onto the squared end of theshaft 23, which projects beyond thecollar 30. The crank is turned, which throws thegears 26, 27 and 28 into action, turning thesleeve 29 but not theshaft 25. The rotation of the sleeve moves thenut 33 along thesleeve 29. Theroller 35 on the end ofarm 34 passes over theroller 36 pushing thearm 34 forward and upward, thearm 34 as it passes upward resting on this roller, whereby it is prevented from breaking under the strain and causing the headpiece to fall, thus jarring and perhaps seriously injuring the patient. The distance through which the headpiece is raised is regulated by the are through which the crank is turned. To lower, the crank is turned in the opposite direction.

If it is desired to flex the knees the attendant inserts the crank into theshaft 38, which sets thegears 39 and 40 in motion, turning the shaft but not the sleeve. Thenut 42 moves along thethreads 41 to any desired distance, w iich again may be regulated by the are through which the crank is turned. T0 lower, the crank is turned in the opposite direction as before.

The advantages provided by my novel cot for the comfort of the )atient will be readily observed. The easy adjustability of the device, its ability to retain its position without slipping, having been once adjusted, the ease with which a patient may be assisted to accustom himself to sitting u during convalescence and while he is sti 1 too ill to be removed from his bed ;--all these features combine to make my device highly comfortable and useful.

It is understood that I do not limit myself to the specific embodiment discussed herein, which is merely for the sake of illustration, as it is obvious that many changes in details of the construction may be made within the scope of the appended claim.

I claim as my invention:

In a cot of the type described, in combination, means to raise a pivoted portion adapted to support the head and trunk of a patient, said means comprising an arm carrying at one end a supporting roller arrange to engage the pivoted portion and being pivoted at the other end to trunnion nuts slidable along a sleeve screw mounted on a shaft, and a second roller at the end of said sleeve screw to support said arm when the head and trunk supporting portion is in raised position and to act as a fulcrum for the aforementioned arm, on which it may slide, and means to operate the sleeve screw.

In testimony whereof, I have signed my name to this specification this 12th day of July, 1924.

ERNST C. ORTMEIER.
