The uprlght members 7 and 7 f whichcar'ry thehmembers S and 8" are adapted to besecurely-fastened to the opposite legs or posts and 7 lto theposts or legs 0 the bed with whlch usedI haveprovided suitable clamping members 2O mid 21. These members when co-act ng form a sleevewhich embraces tended to be used. In securing themembers fthe flegsior postsa of the ibed xand also the members 7 and 7 Suitablebolts 22 are provided forthe purpose of bringingthe members 20 and 21 into close engagement with each other thereby binding the memnection with the legs or posts of the bed.

. In operation the device is attached to the legs orposts of the bed with the base members 12 resting upon the floor. Upon the turning of the crank 19 the bevel ears will cause a rotation of the members and 7. This rotation of the members 7 and 7 will cause elther a lowering or an elevating of the members 8 and 8. This will result in con sequence of the members 7 and 7 being rigidly connected to the posts or legs of the bed, in a lowering or elevating of the end of the bed to Which attached.

pitals where it is sometimes required to'have bers 7 and 7 in rigid and unmovable con I u I a t This device 1s particularly useful-1n hos the headtof the bed higher than the foot of" the bed orvvice versa.

a While I have illustrated and described the preferred form of construction for carryin my invention into effect, this is, capable 0? ing from the spirit of the invention. therefore, do not wish to be limited tothe the construction set forth,

variation and modification without departr but desire to avall myself of such variations 1 1 and modifications ascomewithin the scope of the appended claims.
