Q o Be it known th'atI, THOMAS HQJERvrs, a citizen of. thellnitedv States, residing at Ebensburg, in the county 1 of, Cambria and State of Pennsylvania, haveinvented new and useful Improvements in Gravity-Beds,

lof which the following is a specification.

The "invention relates to beds, and more particularly to-.i the classof gravity beds adapted foreitherfloutdoor .or; indoor sleeping; l 1 The primary obj ect of the invention isthe 1-pro'vision of a bed wherein the same can be shifted through anopening in anout'er wall separating aLrooin from afporch so that the (occupant otthejbed can enjoy either outdoor or'indoor sleeping; I

. "Another object of thelinventionis the pro v vision ofj abedwherebythe occupant can at will pass through an opening in the wall of a building and vice versa without ncessitat ing the oceupantleaving the bed to shift the A further object of theinvention is' the provison of a mo'vable bedof this character ljwherein the occupant can undress and retire in the sleeping-room previous to the passing of the bed onto the 'porchor balcony, thereby} obviating; thel ;'possibility of catching f cold {result'ant from igundue exposure while trans- I ferring the bed from theinterior to thee):-

teriorofthebuilding.

v A still further object of" theirivention is L onretiring canquickly pass from the porch theprovision of a" bed wherein the occupant I bemoved from the room-onto theporch so {thatthe spaeeordinarily occupied by the} bed within the rooinj will be free for other.

Fig. 7 is an enlarged fragmeiitaryS'ectional View of Fig. 2. 2 a Similar reference eharacters indicate corresponding parts views in thedrawings. h Referring to the drawings in detail, A designates a portionof a bedroom and B the porch or balcony, both of which are or the ordinary well-knowii'construetion. In the dividing'wall l0 separating the bedroom A throughout the several from the porch or balcony B is formed arectangulanshaped opening 11' having the usual door casement: 12- through which is adapted to pass theibed13*which has its head 14: I

and foot 15 of the sa neheight with relation to each. other," the legs 16 of which havejsuitably secured thereto wheel forks l7 jwhich are extended through slots 18 arranged in spaced parallel relation to leach othenand" formed in thefiooringl9 of the room A and :porch or balconyB, the forks 17 beingprovided with peripherally grooved rollers or j a I track structure presently described. 1

Thetrack'structure comprises a pair of guideirails 21 on which travel the rollers or p M p t wheelsQOIwhichare'adapted.totravel upon? A-still'further object of the invention is;

wheels 20, the said rails being located beneath the flooring 19 in alinement with the slots and are supported upon swinging cranks 22 pivoted thereto at-opposite ends stationarily mounted beneath the flooring 19, the cranks 22. when shifted belngtde signed to tilt the rails 21- in one direction or of the same and also pivoted in bearings 28 theother, and this tiltingfaction accomplished in a manner presently descrlbed.

Fixed to the under faces of the railsv 21 at i "an" intermediate point thereof are toothed racks 24E which mesh with cog gears 25 fixed tof'a horizontal shaft 26' journaled in suitable bearings stationarily mounted beneath "the jfloor' 19., The shaft 26 underlies the rails 21 and is disposed at right angles thereto to extend crosswise thereof. On one end of the shaft 26 is a beveled pinion 27 with which meshes a beveled gear 28, thesame being fixed to the lower end of a driving shaft 29 flfl mouhted vertically in bearings 30 fixed .within the vertical wall 10 atone side: of the opening 11 therein contiguous to the door casement 12, the upper end of the shaft- 29being provided with a beveled pinion 31 Which meshes with a'corresponding pinion 32 fixed to a hand wheel shaft 33, the ends of which extend beyond opposite faces of the 'wall 10 andc'arry hand wheels 34 of the ordinary well-known construction which are in vconvenient reach of a person'occupying the bed when the latteris eitherpositioned 7 within the room A or-on the porch or bal- ,cony B so that the hand wheel 34 can be rotated for actuating the connections with the rails 21 to tilt the same in a direction to causethe bed to gravitate either-from the porch or balcony B into the room A or vice versa.

' The inner edge of the door casement 12 i has secured thereto a strip; 35 which coexte'nds withthe same and has fitted in opposite faces resilient strips 36 with which con tact=the head 1% or foot 15 of the bed when shifted, these strips being designed to act as shock absorbers and also as weather- 'strlps, as elther the head or foot serve to close the opening 11, irrespective of the bed being positioned upon the porch or balcony .B or within the room A of the building.

section 37 of. the base board is posi- --tioned and fixed at the lower-end of the opening 11 in the wall 10 so as t-OSGI'VQ in closing the space between the legs 16 of the head and foot of the b'edwhen positioned onotheporch or balcony or within the room sojthat this board 37.with the head or foot of; the bed will entirelyclose the opening to exclude drafts of air entering the room] through the opening in the wall 10 of the building. Q, It will be noted that the grooves in the peripheries ofthe rollers or wheels oony B. or vice versa. I n From the foregoing it 1s thought that the 20 will prevent the same leaving the rails 21 of the track structure, when the bed 13. is gravitating in either-direction thereon. The angular disposition of the rails 21 when shifted causes the bed 13 to gravitate 'to the lowermost {pointof the track structure, thereby running the bed through the open ing 11 from the room A to the porchor balranged beneath the foundation, cranks jour-f, naled 1n the outerbearings, tracksjconi 2 direction, of inclination, thereof, a shaft wurnaled n the intermediate hearings and having rack plnionsftoothed'racks on the nected to said cranks for changing j'the track and meshing withothe pinions, a movable object supportedv by "said" tracks ,{and
