MATTRESS-ADJUSTING APPARATUS. 1

Application filed. August 19, 1925. Serial No. 51,152.

My invention relates to a mattress adjusting apparatus and the primary object thereof is to provide a device ofv the type described, in a manner as hereinafter referred to, which may be attached to a bed of ordinary construction and operable to elevate or lower any portion of the mattress to suit the convenience of the bed occupant. Further objects of the invention are to provide an adjusting device of the class stated which is simple in its construction and arrangement, strong, durable and eflicientin its use, compact, and comparatively inexpensive to manufacture and install.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views 2- Figure 1 is a side view of a bed provided with a mattress adjusting apparatus.

Figure 2 is a top plan view of the device.

Figure 3 is a side view of the supporting bar partly in section. v

Figure 4: is an enlarged top plan View of the securing cleat.

Referring in detail to the drawing land 2 respectively designate the head and foot members of an ordinary bed. The head and foot members 1 and 2 are connected together in the usual manner by a pair of angle iron side rails 3. The bed further in cludes the springs t having a mattress 5 positioned therein.

Figure 1 of the drawing, illustrates the application of my improved mattress adjusting apparatus to the foot end of the bed for the purpose of elevating the mattress at that end so that the feet of the occupant will be in the elevated position. It will, of course, be obvious that the apparatus may be connected with the bed in a manner to permit of the adjustment of any portion of the mattress desired.

My improved apparatus comprises a supporting bar 6 which extends transversely across the bed intermediate of the mattress 5 and the springs 4. Each end of the supporting bar 6 is formed with a threaded aperture 7 adapted for the reception of the bearing bolts 8.

A pull bar 9, having a right angularly disp'osed-elevating arm formed integrally with each end thereof-and respectively indicated at and 11, is shiftably supported on the horizontal portions of the side rails 3.

Each of the side rails 3 has a toggle arm 12, 13, pivotally connected to the vertical portion thereof by means of a screw 14. The adjoining ends of the elevating arms 10 and 11 and of the associated toggle arms 12'and 13 are apertured forthe passage of the bearing bolts 8, by which they are pivotally' connected to respective ends of the supporting bar 6.

The threaded ends of the bolts 8 are reduced and when the latter are secured in the supporting bar end apertures 7 they will not lock the elevating arms 10 and 11 and toggle arms 12 and 13 against movement thereon.

The forward end of each of the toggle arms 12 and 13 is provided with a staple 15, 16 disposed on the inner side thereof, and the pull bar 9 is provided with a small pulley 17 disposed'on the inner side thereof. A flexible member or cord 18 passes through the pulley l7 and has one end permanently secured in the staple of the toggle arm 12. The other end of the cord .18 passes through the staple'16 of the toggle arm 13 and is provided with a handle 19 to faci1iv tate the operation of the apparatus.

A cleat 20 is fixed to one of the side rails 3 for the attachment of the cord 18 to hold the device in the adjusted position.

By pulling forwardly on the cord 18 the pull bar 9 will be drawn forwardly toward the head of the bed thereby elevating the supporting bar 6 and the mattress 5 positioned thereon. When the latter is adjusted to the position desired the cord 18 is secured to the cleat 20 for maintaining the mattress 5 in the adjusted position.

What I claim is:

In combination, with a bed, a mattress adjusting apparatus comprising a supporting bar positioned between the mattress and springs of the'bed, each end of said supporting bar formed with a threaded aperture, a pull bar shiftab'ly supported on the side rails of the bed and provided at each end with an angularly disposed fixed elevatvotally connecting itliei'associated"ends of said elevating and toggle arms to respective ends of said supporting bar; a flexible member connected With said pull bar for shifting the latter to adjust said supporting bar, and means for securing said flexible member to maintain said supporting bar in the adjusted position substantially as described and for the purpose set forth.

In testimony whereof I afiix my signature.

FRANCIS P. MOLAUGHLIN.
