THEODORE R. TREIBER, OF KANSAS CITY, MISSOURI.

BED.

To all whom it may concern:

Be it known that I, THEODORE R. TREIBER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Beds, of which the following is a specification.

My invention relates to improvements in beds.

The object of my invention is to provide novel means by which the head, foot or middle portion of a mattress may be easily and quickly raised to any desired position above the normal, without discommoding an occupant of the bed.

My invention is adapted to use at home or in hospitals, and is particularly adapted for clinical purposes.

In the accompanying drawings, which illustrate the preferred form of my invention, Figure 1 is a plan view of my improved mechanism. Fig. 2 is a side elevation showing the middle bed bottom section raised above the normal position. Fig. 3 is an enlarged vertical sectional view on the lines ab of Fig. 1. Fig. 4 is a plan view of the supplemental frame and parts carried thereby, a portion of the bed frame and track being shown partly broken away. Fig. 5 is a vertical sectional view on the line 0-(Z of Fig. 3. Fig. 6 is a horizontal sectional view on the line ef of Fig. 5. Fig. 7 is an enlarged vertical sectional view on the line g-h of Fig. 5. Fig. 8 is a vertical sectional view on the line t-j of Fig. 3. Fig. 9 is a vertical sectional view on the line 7c-Z of Fig. 8.

Similar reference characters designate similar parts in the different views.

1 designates an ordinary iron bed frame provided with the usual angle bar rails 2 to which are secured vertical members 3 which support two longitudinal rails 4, disposed one at each side of the bed frame and which serve as a track on which run carrying wheels 5 rotatably mounted on and supporting a supplemental frame 6. A hor1- zontal transverse shaft 7 is rotatably mounted in the supporting frame 6 and has secured to it two pinions 8 which respectively engage two rack members 9 which are vertically movable in guides 10 with which the frame 6 is provided. Each of the rack members 9 is provided at its upper end with a horizontal flat head portion 11. The head portions 11 are adapted to support and lift Specification of Letters Patent.

any one of a plurality, preferably 3, of bed bottom sections 12, each of which is provided with two transverse bars 13, the ends of which are adapted to rest upon the rails 2, as shown in Fig. 3. The bed bottom sections may be provided with the usual coil springs 14: which support a mattress 15 and which are in turn supported by bars 16, the ends of which are supported by the bars 18. The flat head portions 11 of the rack members 9 are of such a length that, when the supplemental frame 6 is moved centrally, under any one'of the bed bottom sections 12, the heads 11 will be adapted to engage and lift that section independently of the other two.

In order to properly locate the supplemental frame with respect to the bed bottom sections. one of the track rails 4, as shown in Fig. 2, is provided on its outer side with three vertical indicating marks 17 with which the left carrying wheel 5, as viewed in Fig. 2, may be brought into register, thereby locating the three operative positions of the supplemental frame. In order that each bed bottom section may be properly centered with respect to the supplemental frame, each of said bed bottom sections i provided with four downwardly extending tapering members 18, which are secured to the members 16 and are adapted respectively to enter vertical holes 19 providedtwo in each head portion 11 adjacent to the ends thereof respectively. For turning shaft 7 to raise and lower the rack members 9, said shaft has secured to it at one end a spur gear wheel 20 which meshes with a a pinion 21 secured to a horizontal shaft 22 rotatably mounted in the supplemental frame 6 and having a squared out-er end adapted to be fitted in a socket opening provided in a removable crank 23.

'lVhen it is desired to elevate any one of the bed bottom sections, the supplemental frame 6 is moved along the track to a position under said bed bottom section, with which it is properly positioned by reference to the indicating marks 17 as hereinbefore described. The crank 23 is then turned in a direction such that the pinion 8 will lift the rack members 9, causing the latter to engage the adjacent bars 16 of the bed bottom section immediately above, the tapering members 18 entering the holes 19, and by their tapering form bringing the supplemental frame 6 into its proper position relative to the bed bottom section. Continued turning'of the crank 23 will cause the bed bottom section to be lifted to the desired position, in which position it may be retained by means of a gravity actuating pawl 24 which is pivoted'to the frame 6 and engages the teeth of the upper gear wheel 20. To look the supplemental frame against movement on the track a cam lever 25, which is pivoted to the supplemental frame 6 is swung into engagement with the under side of the adjacent track rail l, as shown in Fig. 2.

From the above it Will be understood that the supplemental frame 6 may be moved to a position under the head, foot or middle bed bottom section 12, after whichsaid section may be-lifted to and retained in the position desired.

I do not limit my invention to the structure described and illustrated, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is,

1. A bed frame, two bed bottom sections adapted to be supported by the bed frame, and an elevating mechanism provided with means by which it may elevate either of said bed bottom sections independently of the other. I

2. A bed frame, a plurality of bed bottom sections adapted to be supported by said bed frame, a supplemental frame movable on said bed frame to positions respectively under said bed bottom sections, and means carried by said supplemental frame for vertically adjusting such bed bottom sec-' tion as is above said supplemental frame.

3.
