SPECIFICATION forming part of I Letters Patent N 0. 721,610, dated February 24', 1903.
Application filed September 5, 1902 Serial No. 122,268. (No model.)
To all whom it may concern: Be it known that I, ROBERT SCOTT, a sub- 4 ject of the King of Great Britain, residing at Waipukurau, in the-Colony of New Zealand, have inventeda new and useful OasterAttachment for Bedsteadsi and I do hereby de clare the following to be a full, clear, and exact description of the same.
, The caster attachments to bedsteads that form the subject of the present invention havebeen specially designed for use with hos" pital or sanatorium beds, which are often required to be moved about from place to place without moving the patients therefrom.
' The object of the invention is .to provide means whereby this may bereadily-performed with a minimum of discomfort to such patient. f
The appliances for carrying out the invention'consist of a pair of wheels that are mounted-upon a spindle carried in bearings secured to the legs at one end of the bed. These of levers that areconnected, respectively,
to a pair of levers upon a spindlelmounted in hearings on theother end of the bed. The turning of these levers will cause the wheelspindle to be depressed and that end of the bed raised from the floor, so that its weight will rest upon the wheels. The other end may then be raised by means of its levers acting as handles and the bed be run about on its wheels in the same manner as an ordinary two-wheeled truck. In the accompanying drawings, Figure l is a side elevation of a bed-frame, showing the attachments in'position thereon. Fig. 2 is an end elevation of the same. I v
Ais the bed-frame, of which B represents the four ordinary legs. To the legs at the bottom end of the bed are attached the bearings'O, that are formed with slots ctherein, in which fit the ends of a spindle D. Upon this spindle are loosely mounted the'wheels E, which are mounted the two-armed levers J, one arm of each of which is connected to the spindle D.
by means of the-rigid'connecting-rods-K,
which are forked at'theirlower ends to serve as guides for thegvheels E, The other arm of each of these levers J isconnected by means of the rods L to the shorter arms of a pair of two-armed levers M, that are mounted upon the spindle Hat the top end of the bed.
.The longer. arms of these levers M serve as handles to operate them.
The normalpositions of the different parts I are shown in full lines in-the drawings. Upon raising the long arms of the levers M to the position shown in dotted lines the leversJ will be caused toturn on their spindles, so
as to depress their shorter arms, and with them the spindle D, the end of which will slide down to the bottoms of the slots 0 inthe, bearings O. p The peripheries ofthe wheelsE will thus be caused to press upon the fioor. Upon the motion of the levers being continued the spindle G willbe caused to rise,carrying with them the legs B of the bedstead, so that such legs will be raised free of the floor and that end of, the bed will be carried by the wheels E. By lifting the top end of the bed with the levers M as handles the Whole of the bed will be freed from the floor, and it may be readily moved about upon its wheels'E in the same manner as a truck. The operations of the difieren't lovers. are clearly shown by dotted lines in Fig. 1 of thedrawings.
What I claimas my, invention, and desire to secure by LettersPatent, is-- Ina caster attachment for bedsteads, the
bearings F attached to the legs of the bedstead, levers J and M connected together by a rod L pivoted in the said bearings, bearings 0 attached to the lower ends of the legs at one end of the bedstead and provided with slots, wheels, E normally arranged abovethe floor and having. their spindles guided'in the slots and rods K connecting the spindles of the wheels with the levers J at one end of the bedstead, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
ROBERT SCOTT.
