BED

Filed sept. 15,l 1941 s sheets-sheet s spring and frame to normal horizontal position.

In the modified form of theinvention shown in Figure 7 'a lever 33 is utilized to operate the wedge' members in lieu of the aforesaid chains, sprocket gears and shaft.

In the modified form of the invention bars 3d are disposed. underneath the side rails 35 of the bed spring frame and have anges Sii engaging the outer sides of the bed spring frame the same -as previously described. One of the bars is equipped with a pair of wedge members 31 inclinedfrom their outer ends upwardly and engaging the inclined upper faces of projections 38 at the head di! and foot 4I of the bedstead, see

lFigure 8., The companion bar Sdiis provided with wedge members 42 which are inclined downwardly from their outer ends and ride upon the inclined faces of projections d3 carried by the Vslats 3i', see Figure 9. Both bars are provided with recesses i4 to receive the end portions of the operating lever 33 and are further provided with recesses d5 which receive the end portions of the centrally disposed transversebar or slat 46.

The lever 33 is centrally pivoted on a pivot pin secured to the center of the intermediate slat 46. When the lever is swung in one direction on the pivot pin both ends will move in opposite directions and will slide the companion bars 34 in opposite directtions to move the wedge members in such manner on the projections of the outer slats 31' that the head of the bed spring frame will be raised and the foot thereof will be lowered, the members pivoting on tapered projections 4S carried by plates 5@ secured to the cen'termost slat 45 and received in socket members 5i carried by the side bars 35j of the bed spring frame as heretofore described to form a horizontal axis of rotation for the bed spring frame during such angular inclination of the frame by operation of the lever 33.

The lever is provided with extensible end pory tions 52 which are secured by pins 53 carried by the end portions of the bar and projecting through slots 54 in the extensible end portions.

When the extensible end portionsare pulled out upon either side member 55 of the bedstead the extensible end portions form handles through themedium of which the operating lever 33 may be swung on its pivot.

Since the operation of theparts has been del' scribed as the description thereof progressed, it is thought the invention will be fully understood without further explanation.

What is claimed is:

l. VA. bed comprising'a bedstead, a bed spring disposed upon Vthe transverse bars or slats 31"' pairs of wedge members having side flanges engaging the sides of the bed spring frame to form guides, a centrally disposed slat on the bedstead, a lever pivoted centrally on the central slat and engaged through openings in said anges to actuate the wedge members, movement of the lever in one direction causing the wedge members to tilt the bed spring frame downwardly at an angle while movement in the opposite direction causes the wedge members to return the frame to a level position.

2. A bed comprising a bedstead, a bed spring frame, means mounting the bed spring frame for pivotal movement about a central transverse axis on the bedstead, a slat carried by the bedstead adjacent the head and foot portions below the slat at the head' portion, oppositely arranged bed spring frame, the slat at the foot portion lying in a plane considerably below the slat at the head portion, a longitudinally extending bar on each side of the bed spring frame having oppositely disposed wedge shaped ends resting on the slats and having side flanges engaging the sides of the bed spring frame to form guides, and means for moving the longitudinally extending bars to cause the wedge shaped ends, at` all times engaging the slats, to move on the slats tilting the pivotally mounted bed spring frame.

3. A bed comprising a bedstead, a slat carried by the bedstead adjacent the head and foot portions, a slat disposed midway between the rst mentioned slat, projections on said slat, a bed spring frame above the slats, socket members on the lower sides of the bed spring frame pivotally receiving the projections, the slat adjacent the foot portions lying in a plane considerably below the slat at the head portion, a longitudinally extending bar on each side of the bed spring frame having oppositely disposed wedge shaped ends at all times resting on the slats and side anges engaging the sides of the bed spring frame to form guides, and means for moving the longitudinally extending bars to cause the wedge shaped ends to move on the slats tilting the pivotally mounted bed spring frame.

4. A bed comprising a bedstead, a bed spring frame, means mounting the bed spring frame for pivotal movement about a central transverse axis on the bedstead, a slat carried by the bedstead adjacent the head and foot portions below the bed spring frame, the slat at the foot portion lying in a plane considerably below the slat at the head portion, a longitudinally extending bar on each side of the bed spring frame having oppositely disposed wedge shaped ends resting on the slats and at all times engaging the same and having side flanges engaging the sides of the bed spring frame to form guides, chains connecting the wedge shaped ends Of the longitudinally extending bars, a shaft carried by the bedstead, and gears carried by the shaft and meshing with said chains.
