Filed: 1972-05-09
Abstract: 1319048 Packaging machines STORK AMSTERDAM NV 9 May 1972 [17 May 1971] 21564/72 Heading B8C In apparatus for packaging poultry carcasses and comprising a pusher 23 which pushes the carcass through a shoot 3 and into a bag 39, the shoot having walls pivoted at the top end thereof so as to be moved apart by the passage of the carcass, a pressure member 26 follows the pusher 23 to hold the shoot in expanded form to facilitate bagging. The pusher 23 is carried by the rod 24 of a pneumatic ram 25, the pressure member 26 being slidably received on the rod 24 and connected to rods 27 carrying rings 28 which abut a guide 27a to limit downward movement of the member 26. A pivotal guide plate 18 projects into the shoot 3 and has stops 29 which, when the plate 18 is pivoted forwardly, act as stops for the member 26. The bag is secured to the shoot by clamps 37a, 37b, 38a, 38b, and is held in a guide 40 having an inflatable casing 41. The bottom of the bag is supported on a disc 43 which, after filling of the bag, is lowered and pivoted to place the bagged carcass on a conveyer. The carcass is positioned by means of ribs 16 on the back wall 7 of the shoot, the legs 59 of the carcass being positioned by a pair of pivotal arms 32 which are advanced by a cylinder 35 to strike the guide plate 18 and be pivoted towards one another by the sides of the plate 18. Four shoots are carried by a central shaft 1 and are moved through the four work stations, at the first of which a bag is attached to the shoot, at the second a carcass is introduced into the shoot, at the third the carcass is bagged, and at the fourth the shoot is disinfected.

Controlling different functions by same lever; controlling- apparatus, arrangements of hand and foot gear in conjunction with; pneumatic transmission; pedal levers, mounting, and foot-positioning devices: brakes. fluid pressure. - The control lever of poweroperated mechanism, such as a brake, is embodied in or disposed adjacent to the accelerator or throttle-controlling member so as to be operated positively by movement of the driver's hand or foot in an additional and immediately adjacent path to that traced during normal operation of the accelerator. In the construction shown in Fig. 2, the accelerator pedal b is provided with a stirrup a so that it can be depressed as usual to open the throttle through a rod k and can also be positively raised to act through a rod g on a valve c controlling the vacuum brake cylinder d described in Specification 267,577, (Class 103 (i), Brakes &c.]. The pedal acts on the rods k. g through stops m, h respectively, so as to push but not pull them. In order that a progressively increasing resistance to upward movement of the stirrup a may be experienced the brake piston e may operate a lever n connected directly to the brake rod p and by a spring q to the stirrup. The effect of the vacuum on the valve c may be. .diminished by decreasing the area of the valve stem on which the vacuum acts, and by equalizing the pressure on both sides of the piston part of the valve. In the construction shown in Fig. 6, the brake pedal 5 is situated adjacent to the accelerator pedal u so as to be operated by sidewise movement of the foot without removing the latter from the accelerator. Modifications are described in which (1) the accelerator pedal is centrally pivoted so that it can be rocked in both directions by the foot; (2) the accelerator pedal is operated by the toe and the brake pedal by the heel, a foot rest being provided between the two pedals, and (3) the combined brake and accelerator pedal described in Specification 228,225, [Class 78 (v), Winding and paying-out. apparatus &c.], is provided with a stirrup so that it can be raised by the foot instead of by a spring.
