IMPROVEMENT IN INVALID-BEDSTEADS.

Specification forming part of Letters Patent No. 186,694, dated January 30, 1877; application filed August 19, 1876.

To all whom t may concern Be it known that I, WALTER SPANNER, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, carpenter, have invented certain new and useful Improvements on Invalid-Bedsteads; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to those bedsteads which are constructed with certain devices for increasing the comfort and permitting of the better treatment of invalids than they can receive when occupying the ordinary bedsteads. In other bedsteads for this purpose they have been complicated in construction, and are consequently difficult to operate; while my invention is simple in its construction, inexpensive, and can be operated by any ordinary attendant, and in many cases entirely by the invalid, and Without getting out from the bed-clothes.

It consists, first, of the mechanism by which the bolster-frame is raised to any desired inclination, when so required for the comfort of the invalid', and either by itself or with the entire bottom, so that the body of theinvalid may be placed in an inclined position when such position is found to be necessary; secon, in the combination and arrangement of a table which, when not in use, has the appearance of an ornamental panel inside of the foot-board, and being hinged to the siderails of the bedstead, and in such a manner that when folded over for use it affords all the convenience of an ordinary table; third, in the combination of a book-rest attached to and forming a part of the aforesaid table, which, when not in use, the book-rest is sunk flush in the same, and when in use, the bookrest is simply raised on its hinges, and may be adjusted by means of a hinged rod attached thereto; fourth, in the combination and arrangement of a bed-pan, which, in most cases, may be used by the invalid without any assistance and without leaving the bed, which is attained by means of a prepared mattress and suitable apparatus for sliding the pan from its usual position to that of a given position under the mattress, and again from the sired inclination, when so required, viz: The bevel-wheels g and h, endless screw e, wheel f, portion of the hinged rack K, table D, in two positions, the arm d being pivoted to the side rail A', and, when folded over for use,

rests against shoulders l, (see Fig. 3,) giving the necessary stability to the table when in use. rIlhe other position is when it is folded closely up tothe foot-board, and appears as an ornamental panel. Fig. 1 shows also the book-rest cl2, and supported by the angular rod d3, also, the bolster-frame B, and extensionboard therein B', at an inclined position, the mattress E thereon and on the bottom, and a separate piece, El, in the form of a pad, which is moved laterally in connection with the bed-pan F, (shown in Figs. 2 and 3,) as hereinafter more fully described.

Fig. 2 is a plan, showing the various parts of the bedstead A, viz., side rails A1, end rails A2, posts A4bed-bottom C with frame, aperture O, pan F, rubber cover O2, handle M with axle m, bevel-wheels g h, endless screw e, axle L, and lever N for moving the padblock t and pan-holder w'.

Fig. 3 is a side sectional elevation, showing pad-block t, bed-pan F with pan-holder m', key m, slideways w w, cross-bar C1, stud S for lever N, the key a serving to lock together and to unlock the pan-holder and the block t, by turning the key and causing its bent end to engage with or be released from the block.

Fig. 4 is a side sectional elevation, with f bolster-frame B and extension-board B', and and the links b2 b3 b4 for operating the same, hinged rack K, pinion L', guide k1, sliding stop k2, axle k3, arms lo* for operating the sliding stop k2.

Fig. 5 is a transverse section, showing bottom C, frame O1, slideways w w, rubber cover O2, intended to be air-tight above the pan F.

It will be seen from the drawings that Aon turning the handle M it will rotate the bevelwheels g h, and the endless screw e, wheelf, axle L, pinions L' L', which will give a vertically-reciprocating motion to the racks K K and elevate the outer end of the bolster-frame B, which, after being raised a little, on turning the axle k3, by means of the arms 71:4, will unlock the bottom-frame G5 from the crossbar O3, and will move the catch k2 into the ratchet on back of racks K; and on turning the handle M the bottom C will rise with the bolster-frame B, and to any inclination that may be required. It will also be seen that by moving the lever N on its fulcrum n' it will,

` by means of the stud S, move in either direction the block t with pad El, and also the panholder x' with pan F. When the bolsterframe B is elevated to the position shown in Figs. 1 and 3, it will be seen that the pad El, being secured to the block t, does not rise with the mattress E. An aperture, E2, will thus be formed in the mattress E, through which the pad E1 will be moved by the lever N, without any interruption from the mattress E, as herein shown. 1t will also be seen that as the bolster-frame B rises the link b3 acts as a lever, and pushes out and extends the bolin relation to such bolster, as specified and described.

2. In an invalid-bedstead, constructed with an adjustably-movable extension-bol ster board B', the combination of the links b2 b3 b4, bottom C, hinged racks K K, axle L, pinions L' L', wheelf, enless screw e, bevel-wheels g h,

and axle m, and handle M, as and for the purposes set forth.

3. The combination of the block t, pan F, and pan-holder x', key az, lever N, and slide- Ways w w, as and for the purpose described.

4. The combination of the catch k2, axle k3, and arms 7a4, with the bed-bottom and the racks K, as and for the purpose described.
