ADJUSTABLE HEAD AND BACK REST.
Specification of Letters Patent.
.lr'atentea March 6, 1906.
Application filed June 30, 1905. Serial No. 267,684.
To @ZZ whom it may concerns Be it known that I, WILLIAM H. CARR, of Meridian, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Adjustable Head and Back Rests, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to adjustable head and back rests applied to invalid-beds for the purpose of supporting the occupant of the bed in any desired reclined posture.
The object of the invention is to provide a head and back rests which s hall be simple and inexpensive in construction and convenient and efficient in operation; and to that end the invention consists in the improved construction and combination of the component parts of the head and back rest hereinafter described and as illustrated in the accompanying drawings, in which` Figure l is an isometric perspective view of a head and back rest embodying my invention. Fig. 2 is a fragmentary longitudinal section of the same. Fig. 3 is a detached side view of some of the component parts of the invention. Fig. 4 is an enlarged perspective View of the bar which carries the supportingslats of the head and back rest, and Fig. 5 is an enlarged transverse section on line X Xin Fig. 1.
represents the frame of an iron bedstead, the rails of which are usually formed of angleiron. b represents a shaft consisting of a square bar disposed across the under side of the side rails of .said frame and passing through square holes in cylindrical collars b, which are supported upon bolts o o, connected to brackets p, suspended from the side rails, as shown in Fig. 5. 4
c c are arms which are provided at one end with a square hole by which they are connected to the ends of the shaft t.
b2 represents a lling-block applied to the side rail at the attachment of the brackets p p.
d denotes a flat bar which extends across the bed and has its ends formed in the shape of ears d3 cl3, Which abut on the sides of the arms c c and are adjustably clamped thereon by means of bolts d2 passing through holes c2 in the free ends of the arms and holes in the ears d and provided with heads and nuts.
f f are slats which are mounted transversely of the bar d and firmly secured thereto by rivets or other suitable means.
g represents a lever which is provided with a square orifice g to receive the correspondingly-shaped end of the shaft t. By means of this lever the shaft can be turned to set the arms c c in different angles of inclinations as may be desired by the occupant of the bed. Suitable locking devices are employed to retain the lever in its adjusted position. A simple means for accomplishing this consists of a chain h, suitably connected to the frame a and receiving through one of its links the end of the lever, as represented in Fig. 1 of the drawings.
i denotes the wire woven bed-spring, upon which is placed the mattress fm, as indicated in dotted lines in Fig. 2.
In order to allow the bar d to rest upon the spring 'i when the arms c c are in their lowered position, I form the bar with offsets j, so as to cause the main portion of said bar to be disposed in a lower plane than the end portions thereof.
A secondary adjustment of the slats ff is effected by loosening one or both of the attaching-nuts on the ends of the bar d and turning the said bar so as to impart more orless inclination to the slats, and by subsequently tightening the nuts the bar d becomes rigidly set on the arms c c, and thus the slats are retained in their adjusted position.
To allow the described head and back rests to be applied to beds of different widths, I provide a bar d, which is adjustable in length. For this purpose I form the said bar of longitudinal sections d d, spliced adjustably end to end, preferably by forming said sections of sufficient lengths to cause their ends to lap one upon the other and clamped together by means of a suitable clip or band Z, embracing the lapping portions and provided with a setscrew l, by which to tighten said clip on the bar.
What I claim as my invention is` l. The combination, with the bed-frame, of a transverse shaft pivoted to the side rails of said frame, arms secured to said shaft to move therewith, a transverse bar connected to the free ends of said arms, slats mounted on said bar, and alever connected to the end of the shaft, as set forth.
2. The combination, with the bed-frame, of a transverse shaft pivoted to the side rails of said frame, arms secured to the ends of said shaft to move therewith and apertured at their free ends, a transverse bar clamped adjustably on the arms, slats mounted on said bar, a lever connected to the shaft, and means IOO IIO
for looking the lever adjustably in position, as l llat side of said bar, a lever connected to the set forth. aforesaid shaft, and means for adjustably Io 3. The eomloination,with the bed-fra1ne, of looking said lever in position, as set forth. a transverse shaft pivotally supported on the WILLIAM H CARR 5 side rails of said frame, arms attached to the l ends of said shaft a transversely-disposed l'lat Witnesses: bar, adjustable in length, and clamped ad- J. J. LAASS, justably on the arms, slats mounted on the L. H. FULMER.
