Patent GB-466177-A (GB)
Title: Improvements relating to the opening of collapsed shells of slide and shell containers
IPC: B31B5/78
Filed: 1935-11-20
Abstract: 466,177. Packeting-machines. CRIGHTON, J., and INDUSTRIAL MACHINERY CO., Ltd. Nov. 20, 1935, No. 32188. [Class 94 (i)] Relates to mechanism for opening and erecting a collapsed shell of a container of the slide-and-shell type ready for the insertion of a loaded slide. According to the invention, the mechanism comprises a number of co-operating shell-engaging elements mounted for rotation in the same direction, and a reciprocating member for rotating the elements. The collapsed shells are fed from a magazine 11, Fig. 1, by a reciprocating feeder tooth 12, on to a table 10. A shell comes to rest with a narrow wall 18, Fig. 1a, upwards and beneath an element 21 which is rotatable about an axis parallel with the edge of the shell. The surface of the table 10 is inclined downwards at 10a, adjacent to the element 21, so that the narrow side 18 of the shell is bent downwards about the crease line 55, on its inner edge. The other narrow wall, 19, lies above a second rotatable element 20 which has a nose 32 at its outer end. An abutment 22 is pivoted on a wall of the magazine 11, and a spring 27 urges the forward end of the abutment downwards towards the shell above the inner edge of the side 19. The elements 21, 22 are rotated through 180‹ by a reciprocating rack bar 45. A lost-motion connection, between the bar and the axle of the element 21, delays the rotation of the element 21 while the element 20 is rotating as the bar 45 moves to the left. The movement of the bar first turns the element 20 and erects the side 19 of the shell against the pressure of the element 22. Continued movement of the element 20 brings the nose 32 into engagement with the element 22 and lifts it off the shell, thus permitting the wall 33, Fig. 1a to rise from the lower broad wall 56. The element 21 then commences to rotate and permits the wall 18 of the shell to move away from the wall 56. The movement continues until the shell is finally erected, as shown in Fig. 3, whereupon it is removed by any convenient means. The elements 20, 21 may be operated by camcontrolled lever or other actuating member instead of the bar 45, a slotted link providing the lost-motion connection between the elements 20, 21.

In a modification, Fig. 11, the screed 7B is shaped to form curb only on a made-up road. In a further modification, Fig. 7 (not shown), the screed is shaped to form only a flat side-walk or extension to an existing road. The screed 7 carries supporting side members 19 on the forward end of which is mounted a hopper 8 for concrete fitted with rammers 45 for the concrete or a helical packing conveyer, Fig. 9 (not shown). A plate 47 on the front diverts concrete into the required section. Between the hopper 8 and the screed front is a vibrating strike-off plate 38. Behind the screed and carried on the members 19 is a hopper 9 for fine concrete discharging on to the curb and gutter section. Behind hopper 9 is a trowel 10 shaped in the same form as the screed and vertically adjustable by screw rod 51. The lowest part of the screed is stiffened by a longitudinal hollow member 30. The span of the machine may be altered by moving spacing members 57 to one side or the other of wheels 4.
