UNITED 'STATES PATENT QEEIGE.
WILLIAM V. VAN DERVORT AND ROBERT B. WALKER, OF NEW ANTIOOH, OHIO.
IMPROVEMENT IN AUTOMATIC CRADLES.
Specification forming part of Letters Patent No. 139,838, dated June 10, 1873; application filed May 3, 1873.
Beit known that we, WILLIAM-V. VAN DER- VORT and ROBERT B. WALKER, of New Antioch, in the countyof Clinton "and State of Ohio, have invented a new and valuable Improvement in Automatic Cradles; and we do hereby declare th at the following is a full, clear, and exact description of the construction and operation of the same,reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.
Figure l in the drawing is a representation of our automatic cradle by a central cross-section, exhibiting the construction of the rockers. Fig2 is an end view with the outer headboard removed, exhibiting the motive power.
Our invention relatesto an improved construction of a cradle driven by clock-work, whereby the thrusts of the oscillating motion are greatly lessened, the usual click and noise of the clock movement avoided, and the cradle is prevented from traveling.
A is a foundation-frame, on which the rockers of the cradle oscillate. It is provided with a straight rack, a, into which a toothed sector, b, on the rocker B, is geared. The rocker B is prevented from jumping and throwing the rack a and the sector b out of gear by an arm, C, with a guide-pin, c, which latter slides in a cycloidal groove, c', on the sector b. The arms C may be fastened to the rack a, or they maybe both wrought or cast in one piece. We fasten a sector, b, with the groove c', to eachrocker, and supply the frame A with two racks, a, and guide-arms C, for the purpose of gearing and guiding, as above described. To prevent the rockers from working off their support in a longitudinal direction, we place the racks and sectors on opposite sides of the rockers, by which arrangement the rockers are placed between the arms C, and cannot move away from them. The motor for our cradle is a clock movement incasedin the same near the head or foot board, so that it may be wound H H. The spring lis fastened to the frame A by screws t' i, or otherwise. The above-described construction of our machine has the advantage of working without noise, because there are no pallets and ratchets or palletwheels used to change the rotary motion of the wheel D inthe clocktrain to the required oscillatory motion ofthe cradle, the crank-motion being the only silent connection between cradle and clock movement. Another advantage is this, that the cradle is started when the crank E works with its greatest leverage,I and exercises its greatest power when it is most necessary. The spring I serves to moderate the movements of the cradle, to avoid unpleasant shocks, and to prevent the upsetting ofthe cradle. i
What we claim as new, and desire-to secure by Letters Patent, is
The combination, with a cradle-rocker, of the rack a, arm O, pin c, toothed sector b, cycloidal groove c', substantially as specified. In 4testimony that we` claim the above we have hereunto subscribed our names in the presence of two witnesses.
WILLIAM V. VAN DERVORT. ROBERT B. WALKER.
