Patent GB-133895-A (GB)
IPC: A01K31/16
Abstract: 133,895. Lamb, J. T. March 17, 1919. Nests.-A trap-nest for poultry and the like comprises a nest chamber A, Fig. 1, in which is an inclined nest floor J which directs the egg against a vertical wire frame L suspended by its upper end and fitted with a pad L<3>. Beyond the nest chamber is a corridor B in which is arranged a tilting platform R connected by a lever S and cords to the shutters H, M. The shutter H is supported by a catch G<3> and falls when the catch is moved by a bird coming in contact with the hanging grid G. The shutter M which closes the exit is released when the catch L<2> is actuated by the egg rolling against the frame L. Both shutters are raised when the platform R is depressed, the exit being thus closed and the entrance opened. In the modification shown in Fig. 4, the entrance shutter H<2> is not closed until the egg is laid, being operated by the fall of the heavier shutter M so that the bird can leave the nest at will. The entrance of a second bird is prevented by a hanging grid G<4> which engages a catch Y when the nest J<2>, which is pivoted at J<3>, is depressed. Other forms of the catch Y are described to come into operation either on the raising or lowering of the front of the nest when occupied. If the platform R is short, as shown in Fig. 4, a hanging grid E' forming a non-return door is employed. The hanging frame L is protected by a hood N. In a further modification, the door H<2> is raised by the depression of the nest when a bird enters.

Filed: 1961-04-18
Abstract: 936,933. Weighing apparatus. W. & T. AVERY Ltd. April 12, 1962 [April 18, 1961], No. 13869/61. Class 143. A weight-totalizing headwork is adapted to operate a read-out device for indicating the total load carried by a weigh belt in a given time. A pendulum type load indicating mechanism 3 is connected by a ribbon 4 to a load counterbalancing lever system (not shown) so arranged that the angular movement of the indicator spindle 5 is proportional to the load on the weigh belt. A rotatable cam 12 is carried by a pinion 8 which meshes with a quadrant gear 7 carried by the spindle 5. A reference cam 13 is fixed and is coaxial with the cam 12. Each cam is generally circular and has an arcuate cut-away portion of reduced radius. A shaft is rotated at a speed proportional to that of the weigh belt and carries a spider 15 which in turn carries a pair of rollers 16 which engage the peripheries of both cams. With a load on the weigh belt the movement of the quandrant gear 7 exposes an arc of reduced radius between the cams 12, 13, the peripheral length L of which is proportional to the load, and the rollers 16 drop on to this arc as the spider 15 is rotated. This movement of the rollers causes pawls 17 to engage the teeth of a ratchet wheel 18, which is thus moved proportionally to the speed of the weigh belt and the load thereon. The ratchet wheel 18 drives a multi-lobe cam 24 which operates a microswitch 26 connected to the read-out device. A pointer 6 provides a visual indication of the load.
