BED'STKEAD FOR INVALIDS AND OTHERS.

SPECIFICATION forming part of Letters Patent No. 342,'551dated May 25, 1856.

Y Application filed January ,23, 1886. 'Serial No. 189,460. (No model.) A

To aZZ whom it may concern: Y

Be it known that I, CAsPAR VEBER, a citizen of the United States, residing in the city and county .of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Bedsteads for Invalids, which improvement is fully set forth in the following specitication and accompanying drawings, in which- Figure l represents a side elevation, partly broken away, of a bedst'ead embodying my invention. Fig. 2 represents a top or plan view thereof. Fig. 3 represents an end View thereof. Fig. 4 represents a vertical section of a portion thereof on an enlarged scale.

Fig. 5 represents a horizontal section in line w 5v, Fig. 3, on an enlarged scale. Fig. 6 represents a horizontal section in line y y, Fig. 3, on an enlarged scale.

Similar letters of reference indicate corre-A sponding parts in the several figures.

My invention consists of a bedstead for invalids, Src., the same being easily operated and possessing several advantages, as will be hereinafter set forth.

Referring to the drawings, A represents a bedstead,and B represents a bed-bottoni,wl1ich is connected with rollers C C, which are mounted on a frame, D, thelatter having secured to it rack-bars E, which depend from said frame D, and are fitted in guides Fon the bedstead A.

G represents pinions, which are secured to the ends of a shaft, H, the latter having bearings on the bedstead A and carrying a crank or operating-wheel, J, whereby said pinons may be rotated, it being noticed that the pinions mesh with the rack-bars E, by which provision the bed-bottom B may be raised or lowered, as desired.

The rollers C carry ratchets K,with which engage pawls L,hung on the frame D, it being seen that the bed-bottom D maybe tightened or loosened or its tension adjusted when desired, by properly rotating the rollers, thc pawls and ratchets afterward serving to lock the rollers and preventing improper rotation of the same.

Connected with the ends of the frame D are cords M,whichpass around pulleys N,mount ed at or near the top of the bedstead A, and carrying at their lower ends weights P,which are guidedon vertical bars Q, the latter bestraps Q', which are secured to the weights, so that asv the latter rise and fall they are prevented from swinging and striking the bedstead and making other noises objectionable to invalids.

It will be seen that the bed-bottom may rest on the bed proper, and be occupied in such position.

When itis required to remove the mattress, make or 'air the bed, or elevate the invalid, patient, or occupant, the wheel J is operated, whereby the bed-bottom is raised from the mattress, the invalid remaining thereon. As the bed-bottom rises, the weight P assists the ascent thereof, thus easing the'operati'on of the wheel J.

In order to retain the bed-bottom at its adjusted height I employ a fastening, R, which consists of a bar pivoted to the frame D, and having a cam-head, S, which is adapted to be tightened'against or engage with the guide F, as shown in Fig. 4, thus locking said frame and preventing vertical motion ofthe bed-bottom.

The advantage derived by using the campawl R is that it'does away with the clicking of the ratchetstop heretofore used in bedsteads ot' this character, and which not only annoyed but frightened the invalid, resembling in its noise'the striking or clashing of surgical instruments. By throwing out the bar or fastening the cam -head releases the frame D and permits the same to be raised or lowered.

For treatment of brokenbones,dislocations, 85e., of the limbs, especially the legs, which require to be stretched during such treatment, I employ a weighted cord, T, which passes over a pulley, U,V on a bracket, V, and is connected with a collar or band fitted on the limb. The. bracket is slotted, and the bearings of the pulley are secured in position by means of bolts XV, which pass through the slot and permit the vertical adjustment of the pulley on the bracket. The bracket has its lower 4end forked, as at X, and fitted on a horizontal bar, Y, which latterv is secured to thevframe D ot' the bed-bottom, the bracket thus being capable of lateral adjustment relaof the patient.

ing secured to the bedstead A and enteringtively to the condition of the case or position The bedstead will be found to bewelladaptl@ 3. The rising and falling frame D, in com ed especially for invalids.A Y

I am aware that it is not new to employ cords and weights in connection with grooved 5 rollers secured to a movable bar, the latter being adapted for attachment to the frame of a bedstead for the purpose of raising or sustaining the limbs 0f an invalid reclining on the said bedstead, and such I do not claim.

vIo Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. A rising and falling bed-bottom, in com'- bination with a rack-bar and pinion, a bedx 5 stead and a fastening consisting of a bar with a cam-head, which engages with the bedstead, substantially as described.

2u A bedstead provided with a lateral ad-y justable bracket carrying a pulley having a 2o vertical adjustment and a weighted cord, substantially as and for the purpose set forth.

binntion `with the horizontal barI Y, forked slotted vbracket V, pulley U, secured to the slotted bracket V by bolts W, weighted cords T, passing over said pulley, substantially as and for the purpose set forth.

4. In a bedstead, a horizontal end bar secured to a rising and falling frame, in combination with a slotted bracket having a forked portionadapted for attachment to said bar, said bracket extending outward and upward from said bar, a pulley adj ustably secured to said bracket, and a weighted cord passing over said pulley and through said bracket, all -35 substantially as and for the purposeset forth.

GASPAR WEBER.
