To all whom it may concern.-

Be it known that I, ELZEAR MICHAUD, a subject of the King of Great Britain, residing at and whose post-office address is Montreal, district of Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Head and Back Rests for Beds and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in head and back rests adapted to be applied to beds, the object of this invention being to provide a self-contained device for that purpose which may be assembled for use and readily applied to wood and metal beds without boring or otherwise 'mar-.

ring such beds. To that end the operative parts are all connected with rail-plates which are adapted to rest upon the bed-rails and may be removed therefrom with ease.

the accompanying drawings is illustrated the preferred form of the device, and

it-will beevident that said device may be 'changed in form and in the various proportions without departing from this invention.

Figure 1 is a perspective view of one end of a bed equipped with the invention. Fig. 2 is alfragmentary view illustrating one rail with a rail-plate thereon, to which is connected one part ofthe head andback rest. Fig. 3 is a detaclied erspective view illustrating one of the rail l ateS. Fig. 4 is a section on line 4 4 of Fig. 3, and Fig. 5 is an edge view of one of the rocker-arms of the device.

Referring to the parts, 1 re resents bedrails, upon which rest the rail-p ates '2, which are provided, respectively,with the depending

flanges

3, 4, and 5 and with the upwardlyprojecting serrated segmental flange 6 and also, if desired, with the intermediate de pending locking-flange 7, whichis adapted to end under a flange 1 of a metallic bedframe when the device is used on a metal bed. Projecting through the flanges 4 are pivots 8, upon which are rockably supported the rocker-arms 9, which arms 9 are provided at their lower portions with the inwardly and downwardly bent portions 10, at the lower extremity of which are the pins 11. Said pivots are preferably in the form of bolts which pass under the bed-rails, spanning the space between contiguous flanges and serving as locking means to hold the plates against vertical displacement, though permitting the said plates to slide longitudinally of the side rails of the bed upon which the attachment is placed. The arms 9 are provided with the inwardly-projecting perforated lugs 12, through which pass the spring-actuated rod 13, the lower end of which is serrated to correspond with and engage the serrations 14 of the segment 6. A spring 15 surrounds the rods 13 and bears against the thickened portion 16 to force said rods downwardly, so that the serrated head portion 17 of said rod will engage with the serrations 14. The upper portions 18 of the rocker-arms 9 are recessed, and in said recesses are placed the lower end ,of the frame 19. The recessed portion 18 may be screw-threaded for engagement with said frame. Secured by the clips 20 are levers 21, which engage the rods 13 and by means of which the head portion 17 of said rods 13 may be lifted to release said head portion from engagement with theseg- 4 ment 6. Connected with the perforated flanges 5 are springs 22, to the opposite end of which are connected adjusting-links 23,

which links are provided with a series of notches 24, which notches are adapted to engage the pins 11 to connect said springs "22 with the depending portions 10 of,the rockerarms 9, and it will be,evident-"that the tension of the springs 22 may be readily adjusted by means of the talie1 uplinks 23. Extending longitudinally of the plate '2 is a rib 2*, which serves as a reinforce for said rib.

Owing to the fact that the rocker-arms and the springs are both connected to depending flanges of the plates 2, it is evident that the device herein illustrated is a self-contained head and back rest which may be readily applied to bed-rails whether said rails are of wood or metal, and when used with metalrails the depending flanges 7 may be bent inwardly, as shown in Figs. 3 and 4, to prevent springin of the plates 2 under stress of the IOC springs uring operation of the device. As this device is intended for use especially in hospitals the manipulating-levers 21 are carlied to the upper extremity of the frame 19,

so as to be out of reach of the patient occu- I05 pying the bed under normal conditions.

What I claim is I 1. In a detachable head and back rest, raillates having depending flanges, a serrated ocking-segment, integral with one of said no rail-plates, a pivotally-supported frame and locking means carried by said frame.

2. In a detachable head and back rest, railplates having integral depending flanges, springs connected with some of said flanges, a pivotally-supported frame, depending extensions on said frame, cooperating with said springs and means for locking said frame in different positions.
