Specification of Letters Patent.

Patented Apr. 8,1913.

To all whom it may concern:

Be it known that I, EDGAR R. LOWEREE, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Beds, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in beds, and more especially to beds which are adapted for invalids or for performing minor operations.

An object of'the invention is to provide a bed construction wherein the portion thereof for supporting the person may be bodily adjusted vertically or wherein one end may be raised and the other end depressed.

A further object of the invention is to provide a bed of the above character wherein the support for the person may be swung relative to the bed frame about a central pivotal point A further object of the invention is to pro-' videa bed of the above character wherein the supporting portion for the person is formed in sections, certain of which may be adjusted angularly relative to the other.

These and other objects will in part be obvious and will in part be hereinafter more fully described.

In the drawings, which show by way of illustration .one embodiment of the invention: Figure 1 is a perspective view of a with the supporting portion in raised position. Fig. 3 IS a plan view of the'bed showing the supporting portion turned at an angle to the bed frame. Fig. 4 is a detail in section showing the pivotal sup'port connecting the support for the mattress to the supporting frame therefor. Fig. 5 is a detail in side elevation showing one end of the mattress support raised and the other end depressed.

In carrying out my invention I have provided a bedstead frame which is of the usual construction, consisting ofa head frame 1, a foot frame 2, and side frames 3, 3. These parts may be secured together in any desired way so as to form a rigid structure. Mounted on the bedstead frame is a mattress support 4, on which rests a mattress 5. This mattress is made as herein shown in three sections 6, 7 and 8. The central section 7 is secured to the mattress support by a pivot pin 9. The section 6 of the mattress has two side bars 10 rigidly fixed thereto.

These side bars project beyond the section 6 and are pivoted at 11 to the section 7 of the mattress. Likewise side bars 12 are rigidly secured to the section 8 of the mattress and project beyond the same and are pivoted at 13 to the section 7 v The sup-porting frame 4 for the mattress is preferably formed of angle iron and con sists of side and end bars which are rigidly attached to one another and also flat crossbars which are suitably spaced and riveted to the horizontal members of the side bars forming the mattress support. As clearly shown in Fig. 5,- the sections of the mat tress may be swung to various angular positions relative to each other. The section 6,

as shown in this figure; is swung about the pivotal connection 11 and is held in angular or raised position by asupporting bail 14 which is pivoted to the outer end of the section 6 and rests on the mattress supporting frame. A wire handle 15 may be secured to the outer end of the section 6 to facilitate the raising and lowering of the same. In this figure the section 5 of the mattress is swung about the pivot pins 9 and is held in this angular position by the lower end or edge of the section 8 of the mattress which. rests on the supporting frame. It will be obvious that other adjustments of the sections of the mattress relative to each other and the supporting frame may be made.

While I have used the term mattress, it will be understood that this term is used in its broadest sense and is intended to include the use of coveredspring sections, tufted felted sections, or any other desired form of-cons'truction.

The mattress support 4 is carried directly by a supporting frame 16 which, as herein shown, is formed of angle bars or irons which are rigidly attached together. Said frame also includes a crossbar 17 which is rigidly secured at its outer end to the crossbar forming a part of the supporting frame. These angle bars are. so shaped that the upper edgesof the vertical flanges lie in a horizontal plane. The mattress support is attached to this supporting frame by apivot bolt 18. This pivot bolt extends through the central crossbar secured to the mattress support and also through a central crossbar 17 carried by the supporting frame. A sleeve 19 encircles the pivot bolt and forms a rest for the crossbar of the mattress support, as shown in Fig. 4. A nut 20 is threaded onto the pivot bolt 18 and retains the mattress support on the supporting frame. This connection between the mattress support and the supporting frame permits the mattress support to be turned about the pivot bolt 18 as a center. The upper edges of the angle bars forming the sup porting frame 16 engage the crossbars on the mattress support and serve as a means for preventing the tilting of the mattress support on its pivot. In other words, the mattress support 1 rests on the frame 16 and the pivot bolt 18 merely serves to guide the mattress support as it is swung on the frame and also holdsthe mattress support on the frame.

While I have shown the supporting frame 16 as rectangular, it will be obvious that this frame may be made circular or any other shape. While I have shown a pivot bolt for connecting the mattress support to the frame 16, it will also be obvious that othgr forms of pivotal connections may be use The supporting frame 16 is connected to the bedstead-frame by devices which may be used for bodily raising and lowering said supporting frame relative to the bedstead frame. These devices in the present embodiment of my invention consist of two E parentthat the frame 16 is pivotally conpairs of parallel links or bars 21 and 22. The links 21 and 22 atone side of the bedstead frame are secured to the same pivot bolt 23, while the links 21 and 22 at the opposite side of the bedstead frame are secured to a similar pivot bolt 23. The lower ends of the links 21 are connected to a crossbar 24: which projects beyond said links. Aninclined track or guide 25 is attached to the bedstead frame and the projecting end .of the rod 24. extends into said track or guide. There is a similar guide or track for each end of the rod 24. This guide is formed of. a U-shaped bar which is secured at one endto the side frame of the bed. Said guide is arranged at an angle to the side frame and its other end is attached to the head frame of the bed at a point below the attachment of the side frame thereto. The links 22 are attached to a crossbar 26. The ends of the crossbar project beyond the links 22 and engage tracks or guides 27 which are similar in shape to the guide 25, but incline in opposite directions thereto.

The supporting frame 16 is raised by drawing the , crossbars 25 and 26 toward each other along the supporting guides or tracks therefor. The means for moving the rods 25 and 26, as herein shown, cons1st of a cenframe.

sesame tral shaft 28 which is mounted'in suitable brackets 29 carried by the side frames of the bed. This central shaft is formed with laterally projecting arms 30 and 31. There are two arms 30 and these arms are located adjacent the outer ends of the shaft but inside the supporting brackets therefor. There are likewise two arms 31 which are similarly disposed. Each arm 30 is iconnected by a link 32 to the crossbar '26, while each arm 31 is connected by a link 33 to the crossbar 2 1. It will be apparent that when the shaft 28 is rotated so as to move the laterally projecting arms from. a horizontal position, as shown in Fig. 1, to a vertical position, as shown in Fig. 2, that the cross ars 25 and 26 will be moved to- Ward each other and thus raise the supporting frame 16 bodily from the bedstead When the shaft 28 is turned in an opposite direction the crossbars 25 and 26 ,will be moved away from each other and allow the supporting frame 16 to be lowered. As a means for holding the shaft 28 in varigous positions I have provided a ratchet wheel 34. A pivoted locking pawl 85 is adapted to engage the ratchet wheel and hold the shaft 28 from rotating. The lock- 'ing pawl 35 is provided with a finger piece .36 which projects below the side frame of 'the bed and serves as a handle for throwing the pawl outof engagement with the ratchet wheel. Each end of the .shaft 28 is ;formed with a squared Ito receive a crank 38.

portion 37 adapted From the above description it will be apnected with the links 21 and 22. In order to hold this framefrom turning about this pivotal connection, I have provided a pair f links 39 which are pivoted at one end to the supporting frame, and at their other end to the outer end of the arms 31. "are so disposed relative to the links for rais- These links ing and lowering the supporting frame as to hold said supporting frame in substantially horizontal position when raised and when in lowered position. The links will also hold this supporting frame substantially horizontal while it is being bodily raised from lowered position to raised position. I have, therefore,.provided means for bodily raising the mattress support from the bedstead frame to raised position without tilting the same or without moving the same endwise relative to the bedstead frame. When the supporting frame is either in lowered position or in raised position the mattress support may be swung about its pivotal connection therewith. When in lowered position the ends of the mattress support will swing between the bars forming the end frames. Furthermore, it will be noted that when the supporting frame is in lowered position, as

shown in Fig. 1, the crossbars 24 and 26 have moved downthe inclined tracks or supporting frame and depress-the other, the

shaft 28 is turned in a reverse direction from the position shown in Fig. 1. This movement of the shaft 28 carries the laterally projecting arms 29 below the shaft and as the links 39 are pivoted to the outer ends of these arms 29 the end of the frame 16 to which the links 39 are attached will be held down or depressed, while the central portion of the frame 16 will be raised, which results in a tilting of the frame 16, as shown in Fig. 5. The links 39 are each formed with a deflected portion 40 which permits. this swinging of the arms 29 without the links coming into contact with the operating shaft 28.

From the above description it willbe ap-' parent that I have providedja bed construction which consists of few parts and-which can, therefore, be cheaply made and easily kept in order. This bed construction also permits of the bodily raising and lowering of the supporting portion for the person and also the swinging of this supporting'portion at anangle to the bed frame. By these adjustments the supporting portions of the bed for theperson may be quickly adjusted for such conditions as may arise either in a.

case of sickness or in the performing of minor operations. V

It is obvious that minor changes in the details of construction and arrangement of the parts may be made without departing from thespirit of the invention as set forth in the appended claims.
