child's cot.
Figures 8 to 11 show an alternative arrangement to that shown in Figures 1, 2, 5,
6 and 7.
Figure 8 being a front end elevation of said cradle and rocking device.
Figure 9 a side elevation of same.
Figure 10 and 11 show details.
In the construction represented in Figure 1 the body of the cradle B rests upon
knife edge bearings s on the support a a of the cradle frame A. To the frame A there
is attached a box & in which there is a train of wheels, which by means of a spring
actuates a disc c. The disc c is provided with a crank pin e' which is connected by
the springs or rods with the books d provided on the lower part of the cradle.
By the turning of the disc c as hereinafter described the cradle B is alternately drawn
towards one or the other side, and so caused to rock.
The clockwork actuating mechanism employed for the above purpose is repre-
sented in Figures 3 and 4. The spring drum e operates, by means of the tooth
wheels g and h, the pinion i which is firmly connected to the disc c by a shaft.
The cradle itself, in this case serves as a regulator or pendulum but if necessary, it
can be made heavier by a weight (see Figure 5). If, for example, the spring drum e
turns 8 times, the wheel y turns 50 times, the wheel h 800 times and the pinion i
8000 times; this is sufficient to keep the cradle in motion for 3 hours.
In the arrangement shown in Figures 5 and 6 the cot A¹ hangs on the knife
edges s¹ on the uprights t¹ and 2 and is provided with a pendulum or lead weight p.
In this arrangement the clockwork contained at b is provided on the upright in
the same way as in Figure 1 to give rotation to the disc c. The two rods k are
connected with the crank pin c and with the cot A' by means of the steel springs l.
The spring m ensures a quiet movement to the cot.
Figure 7 shows how this invention can be applied to any cradle, namely by placing
the clockwork contained at 62 under the cradle, bed or cot, and connecting the latter
to the rotating disc by the rods and the elastic bands . As by this application
a strong spring becomes necessary, it is desirable to wind up the clockwork by means
of several intermediate wheels.
In figures 8 to 11 the following modification of the rocking cradle is shown.
The cot B is suspended between the uprights A A by means of two steel bands uu
the latter swinging in the hooks er and fastened respectively to A and B.

page_text: The clockwork mechanism at 6 is fixed to the uprights A A and rotates the crank
disc e bearing the pin c¹ which gives to the lever ea to and fro motion. The lever e¹
is connected by means of the link with shaft o, whereby a rocking to and fro
motion is transmitted to the bar a which is also adapted to the shaft o. The upper
end of the bar a is formed with a slot d in which slot slides the pin d' which is
fastened to the cot B, while the bar a gives to the latter the rocking motion.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what 1
claim is.
1st. A cradle suspended at two points and set in rotion or rocked by means
of clockwork actuating mechanism through a disc such as c. crank pin or pins
such as c¹, and connecting springs or rods such as f which are connected with
the cradle by means of the hooks a substantially as described.
2nd. A cradle suspended at two points and set in motion by a clockwork,
fastened to the uprights A A, rotating the disc c transferring by means of the
crank pin e' a reciprocatory notion to the lever e the latter being in connection
with shaft and lever e giving a to and fro motion to the bar a which is formed
with a slot d' on its upper end for the reception of the pin d, which is fastened
to the cot B causing the rocking of the latter; substantially as described.
