This invention relates to certain improve- :ments on the invalid-bedstead for which Letters Batent No. 125,491 were granted to me l `the/9th day of April, 1872. The object of the present invention is to obtain the transmission of greater power from the operatingcrank to the vertically-adj ustable frame, as the direct turning of the geared cams specied in my above-named Letters Patent is frequently too difficult for persons of little strength. The present invention consists in the combination, with the geared segments that hold the elevating-arms, of a longitudinal shaft carrying pinions that match into said segments, and of a transverse operating-shaft, which is, by Worm and worm-wheel, connected with the longitudinal shaftto turn the same. By this transmitting mechanism the labor of elevating or lowering the invalidcan be easily performed.
A in the drawing'is the bedstead-frame. B
` is the vertically-adjustable frame, constituting the direct supportof the patient. a a are the arms which support the frame B, in the manner specified in my above-named Letters Patent. The arms a. a. are rigidly connected with toothed segments O G', which gear into one another at each end of the bedstead, and
which also gear into pinions b b vmounted upon a longitudinal shaft, D, that hangs in the bedstead-frame A, as shown. E is a transverse shaft, hung in the frame A, and connected by Worm and worm-wheel d with the shaft D.
By means of a crank-handle, e, the shaft E can be revolved to also turn the shaft D, and cause the segments O C to be vibrated, and Withithem the arms a a, for the raising or lowering of the frame B. The segments O C', gearing into each other anda-lso into the pin-` ion b, are thereby supported or braced to cause the arms a. to be. held rigidly in whatever position they may be pnt. The use of worm and Worm wheels makes the employment of clicks or pawls for locking the shaft D unnecessary. l
Having thus described my invention, I
claim as new and desire to secure by Letters Patent- The combination of the arms a a and toothed segments C C with the pinion b, shaft D, worm and worm wheel d, and shaft E, substantially as herein shown and described.
HENRY A. SCOTT.
