Definitions

• This invention relates to hospital equipment, and it consists of an'apparatus adapted to be used in lifting sick persons from their cots or beds, holding them in a comfortable position 5 while their cots or beds are being re-arranged, changed or made up, conveying the patient from one room to another, and to gently replace them upon their cots or beds.
• An object of this invention is to provide an .invali'd elevator comprising an upright mobile frame havingcross-bars fixed-thereto at its upper end, and having a; longitudinally divided platform and means for raising or lowering the platform by mechanism; supported by said cross-bars.
• Another object of this invention is to provide a body-lifting-frame for supporting the platform members, the said frame being designed to be raised or lowered ateither end so as to adjust the platform in any desired angular position,
• Another object of this invention is to provide a longitudinally divided platform supported by jointed members including an elbow joint 25 which can be broken only in an upward direc tion, so as to permit the folding of said jointed members for moving said platform members into an inoperative upper position.

• Figure 'l is a fragmentary front view of the head rest.
• the numeral ill indicates my invalid elevator, comprising an upright mobile frame ll of rectangular cross-section and mounted on four upright tubular posts l2.
• the posts i2 are se- 10 cured on two sides by two elongated rails l3 positioned at the upper portion of the posts, and bytwo elongated rails l4, slidably mounted on the posts.
• Rails l5 Fixed to the posts l2 are rails l5 which are shorter than the rails l3 and I4, the rails l5 be-' ing positioned in right-angular relation with the ..rails l3 and it and define the ends of the frame I l.
• the posts 12 have swivel casters H at their lower ends to enable the invalid elevator to be 2 readily steered into position around a bed.
• Figures l, 2, and'4 show a conventional bed l3 drawn in dot-and-dash lines, the posts l2 being suitably spaced apart to provide large clearances between the bed It and the frame ll.
• brackets 20 Secured to the upper rails l3, l3, are crossbars l9, l9, having secured at their midportions brackets 20.
• the brackets have apertures 2
• the heads 23 of the screws 22 rest on the brackets 20, with the body of the screws in an uprightposition.
• the I lower ends of the screws are journaled in gear housings 24, which are open at two side walls at their lower ends.
• 1 v -Mounted on the screw 22 is a threaded memher 26 havingpivots 21 passing slightly into the member 26, up to the screw 22, and which pass through arms 28, 28 at one end of a bodylifting-frame 29 and provide a pivotal mounting for said frame.
• a threaded member 30 having pivots 3i passing slightly into the, member 30, up to the screw 22'. and which-pass through arms 32, 32 at the opposite end of the body-lifting-frame 29 and provide another pivotal mounting for said frame.
• Elongated aper tures 33 have been provided 'in-thearms 32, 32'
• Bevel gears 34 have been mounted on'the lower ends of the elevating screws 22 and 22'.
• the bevel gears 34 are in meshed engagement with bevel gears 35 secured to shafts 36 which are mounted transversely of the gear housings 24.
• the shafts 36 have handwheels 31 for manual operationof the elevating screws.
• the handwheels provide means whereby each end of the body-lifting-frame 29 may be separately raised or lowered.
• links 40 have been mounted on pivots 4! at opposite sides of the body-lifting-frame 29.
• Pivotally mounted on pivots 42, at the lower ends of the links 40 are arms 43 which form elbow joints 44 with said links.
• Each.pair of arms 43, lengthwise of the invalid elevator, are integrally secured to a platform member 45, the said platform member being in right-angular relation with the said arms.
• the frame 29 On rotation of one of the screws 22 or 22', the frame 29 assumes an angular position and causes the platform members 45 to assume an angular position and to be raised or lowered. It is to be noted that the screw 22 has a right-hand thiead and the screw 22' has a left-hand thread so as to permit rotation of both screws simultaneously and to raise both ends of the platform when turning both handwheels 31 in one direction.
• the two platform members 45, 45 jointly provide a longitudinally divided platform.
• the members 45, 45 may be separately and successively swung under a patient. and adapted for attaching to a pin 48 serve for locking the platform members 45, 45, for maintaining the said members in aligned horizontal relation adapted for supporting an invalid thereon and preventing the platform members from spreading apart.
• a head rest ( Figure '7) is suspended from a hand lever 6
• the bar 63 is carried by an'extension 64 of the frame 29.
• the bar 63 has an arcuate rack 65 at one side.
• carries a pawl 66 actuable by a spring 61.
• the head of a person may be raised by the head-rest relative to his body on the platform.
• the body may be raised and lowered by operation of the hand wheels 31. It
• the invalid elevator may be moved on its swiveling casters to straddle a narrow-bed or cot such as are used in hospitals. It is also apparent that by raising the platform members, one end more than the other, that the body of the patient will be positioned angularly with respect to the bed.
• the inoperative or folded position of the pivoted links and platform members is attained by manually raising the platform members, this upward movement being automatically facilitated by the counterbalancing effect of the counterweights 54, which hold the platform members in the out of the way position above the bed.
• the platform members are provided with a commode-opening 68.
• the platform has a pair of leg-supporting sections 69, 69 extending outwardly from one end of the platform members.
• the leg-sections are positioned above the bot tom surface of the platform members so as to Latch means 46 pivotally. mounted at 42 conform to the shape of the body of the person resting on said platform.
• leg-supporting sections as a unit with the platform .members 45, its is to be understood that the members 69 are detachable from the platform members 45.-
• the members 69 have flanges 25 having bayonet joints (not shown) cooperating with bolts in the ends of the members 45 for suitably connecting these members.
• the rails l4 have upwardly extending arms 10 carried by flat leaf springs 1
• the links 40 have elongated slots 15 in alignment. with the pivots 4i and positioned below the pivots.
• the slots 15 allow a vertical clearance for a slight raising of the platform. members so that .the said members will be adapted for sinking into the soft bedding material.
• the platform members 45 are spaced apart throughout their entire length so that the soft bedding material may rise up to contact the body of the patient.
• elbow joints 44 can be broken only outwardly and upwardly so as to permit the folding of the jointed members 40 and 43 for moving the platform members 45, 45, into an inoperative upper position.
• the elbow joints 44 prevent the members 45 from opening-up while in latched position.
• a body iifting platform made of two independently supported members which make it possible to first push one platform. member with ease under the patient and then to push the other platform member with ease under the patient necessity of raising the entire body of the patient off the bed at one time, which would require the raising of a. considerable weight and causing discomfort to the patient.
• My invention provides a longitudinally divided platformextending integrally from end to end so as to provide support all along the entire extent of the patient. The patient is comfortably supported while being entirely free for movement in an upward direction, as there is no restraining mechanism above the body of the patient.
