I JACOB MICHEL, on NEW YORK, N. Y.
IMPROVEMENT IN INVALID BEDST'EADS.
Specification forming part of Letters Patent No. 160,694, dated March 9, 1875; application filed December 24, 1874.
To all whom it may concern:
Be it known that I, J AGOB MICHEL, of the city, county, and State of New York, have invented certain new and useful Improvements in Invalid-Beds, of which the following is a specification:
This invention is illustrated in the accompanying drawing, in which Figure l represents a longitudinal vertical section of my bed when the headpiece is in a horizontal position. Fig. 2 is a similar section when the head-piece is in an inclined position. Figs. 3 and 4 are side views of the stop mechanism in different positions.
Similar letters indicate corresponding parts.
This invention consists in combining with the head-piece of a bed two racks, which connect with the head-piece by hinged braces, and to which a sliding motion can be imparted by a crank-shaft and pinions. said head-piece being provided with hooks or slotted straps, which catch over studs secured in the frame supporting the bed in such a manner that when the crank-shaft is turned in the proper direction the head-piece is first moved back and then gradually raised to an inclined position.
In the drawing, the letter A designates a frame, which supports my bed or mattress. The lower portion B of this mattress is firmly connected to said frame, while the head-piece O rests loosely thereon, being retained in position as will be presently explained. From the under surface of the head-piece, near to its junction with the lower portion B of the mattress, project two hooks or straps, a, close to the side rails of the frame A, and these hooks catch over studs 11, which project from the inner surfaces of said side rails. The upper or outer end of the head-piece O connects, by two hinged braces, c, with two rack-bars, d, which slide in guide-grooves provided on the inner surfaces of the side rails of the frame, and which engage with pinions e, mounted on a shaft, f, which extends transversely through the frame A, having its bearings in the side rails of said frame.
When the shaft f is turned in the proper direction, the head-piece G first slides back until the bights of the hooks to strike the studs 12, and then the outer or upper end of said headpiece is gradually raised to an inclined position, as shown in Fig. 2. In order to accomplish this purpose the sliding motion of the head-piece is indispensable; otherwise said head-piece could not be raised to an inclined position, or a gap would have to be left between the head-piece and the lower portion of the mattress.
On the shaft f are mounted ratchet-wheels 9, close to the outer surfaces of the side rails of the frame A, and stop'pawls h, which are hinged to said side rails, can be thrown in gear with said ratchet-wheels, so as to retain the head-piece at the desired inclination. Each of the pawls h is provided with a stop, 7;, by means of which it can be retained in a raised position out of gear with the ratchet-wheel.
After the head-piece has been brought to the desired inclination the pawls h are thrown in gear with the ratchet-wheels; but when it is desired to lower the head-piece, or to bring it back to its horizontal position, the stoppawls must be raised so that the shaft f can be turned backward.
By this arrangement the head-piece O can be raised or lowered without disturbing the person occupying the bed.
What I claim as new, and desire to secure by Letters Patent, is-
The combination of hooks or straps to, studs 6, hinged braces c, and sliding rack-bars d, with the headpiece G of a bed or mattress, and with the frame A supporting said inattress, all constructed and operating substantially in the manner shown and described.
.In testimony that I claim the foregoing I have hereunto set my hand and seal this 18th day of December, 1874.
JACOB MICHEL. n s]
