Abstract: 1305933 Endless conveyers CONDECO AUTOMATION Inc 13 Feb 1970 [14 Feb 1969] 7015/70 Heading B8A Engine valves 29 stored on shoots 26 arranged along a conveyer are delivered to load receiving spaces 36 of the conveyer which comprises an endless chain 22 mounting a plurality of L- shaped elements 24. The elements are spaced apart to form the receiving spaces 36 and the free ends of the elements serve to prevent ingress of the valves on the shoot on to the conveyer between the spaces 36. In these spaces already occupied by a valve the valve serves to prevent ingress into said spaces of valves from the shoot. The valves rest on guide rods 16 and are moved therealong by the elements 24, the chain 22 being guided by guides 14, 20 mounted on a back bone 10, 11. The conveyer has a horizontal load receiving portion and an inclined portion, at the upper end of which the guide rods 16 extend laterally away from the endless chain and downwardly to feed the valves under gravity to a further series of machines. Alternatively the inclined portion of the conveyer may lead to an upper horizontal portion wherein the guide-rods (16), Fig. 7 (not shown), have a number of branches (84) controlled by a switch (86) actuated by an air cylinder 92 controlled by the requirements of each of the further series of machines. The endless chain 22 is driven by a motor (72), Fig. 6 (not shown), through a torque limiting device (68) of the ratchet type. The arrangement being that should an engine valve become jammed and the tension in the chain 22 thereby exceed a pre-determined amount then the device 68 will make and break the drive to impart an intermittent motion to the chain and thereby free the jammed valve.

Title: Improvements in and relating to brake actuating mechanism
IPC: F16H21/10
Filed: 1938-03-08
Abstract: 515,564. Vehicle brakes. CROWE, E. F. S. March 8, 1938, No. 7267. [Class 103 (i)] In vehicle brake operating mechanism, a common connection by which front and rear brakes are operated from the pedal &c. is rendered inoperative in so far as the application of the front brakes is concerned, by resilient means, until a predetermined pressure has been applied' to the rear brakes. The pressure applied to the front brakes may increase at a greater rate than that of the rear brakes. and may reach a greater maximum. The pedal 1 is secured to the casing 3 of a Bowden mechanism, the cable 9 of which is connected to the front brake of, for example, a motor cycle and to the operating rod 5 of the rear brake. A spring 7 is seated at one end on a sleeve 4 secured to the pedal and at the other end on an abutment 8 on the rod 5. Pressure applied to the pedal is transmitted initially only to the rear brake through the spring 7 until the spring yields permitting the casing 3 to slide on the cable thus applying pressure to the front brake and further pressure to the rear brake. The cam lever of the front brake may be longer than that of the rear brake so that the pressure on the front brake rises more rapidly and attains a greater value than that of the rear brake. In a modification, a two-armed lever pivoted at a middle point on the pedal arm 1<1> is connected at its upper end to the rear brake rod and at the lower end to the casing of a Bowden mechanism connected to the front brakes, one cable end being secured to the arm 1<1>. A spring which engages the upper arm of the lever and the arm 1<1>. determines the rear brake pressure at which pressure is applied to the front brake. The resilient means may instead comprise the brake return springs, that of the front brake being stronger than that of the rear brake. The resilient device may be placed in the front brake transmission line and operate by holding the front brake in the off position until a predetermined pressure has been exceeded.
