Abstract

The electric opener for oysters and similar bi-valve shell fish includes a needle which oscillates longitudinally to penetrate between the two halves of the shell. An electrically powered vibrator provides drive for the needle. The needle is mounted on the end of a steel rod (5) which is drawn to an elctro-magnet (1) on a.c. peaks and forced away by spring forces (9) at current zeroes. The electric supply is via a cable (11) and is controlled by a switch (12) mounted on the casing (2) of the unit. Two sleeve bearings are provided one (4) next to the electromagnet and the other (8) near the needle exit. The rod is shaped to prevent rotation as it vibrates. To reduce external vibration a rubber sleeve (10) is placed under the spring (9) to provide damping action.

Description

La présente invention concerne un couteau électrique conçu pour être utilisé à l'ouverture des huîtres au moment de leur consommation ou pour effectuer une opération appelée "détroquage" dans les établissements ostréicoles. Le "détroquage consistant à séparer les huîtres une à une. The present invention relates to an electric knife designed to be used when opening oysters at the time of consumption or to perform an operation called "unhooking" in oyster establishments. "Detroach consisting in separating oysters one by one.

Actuellement, le travail d' ouverture - dit de séparation du ccu- vercle, de la coquille, est effectué à l'aide d'un couteau manuel dont il faut se servir avec effort et précaution.Currently, the opening work - called separation of the cover from the shell, is carried out using a manual knife which must be used with effort and care.

Le couteau décrit dans la présente invention permet de rendre ce travail plus aisé, de ce fait accessible à de plus nom- breuses personnes et aider à l'augmentation de la consommation des huîtres,
Ce couteau est basé sur le principe de l'utilisation de vibrations produites par un vibreur électrique, appliquées à une lame de forme appropriée qui pénètre très aisément dans la jonction du couvercle et du corps de lthuStre. The knife described in the present invention makes this work easier, thereby accessible to more people and helps increase the consumption of oysters,
This knife is based on the principle of the use of vibrations produced by an electric vibrator, applied to a blade of suitable shape which penetrates very easily into the junction of the cover and the body of the body.

Le dessin annexe représente la vue extérieure et différentes coupes du couteau. Il comprend : un vibreur électrique I encastré dans un bottier arrière 2, solidaire d'un boitier avant 3 par un système de fixation quelconquee Entre ces deux boîtiers vient s'intercaler une entretoise 44 Une tige centrale 5 reçoit à son extrémité intérieure une masselotte 6 et de l'autre côté la lame 7. Ces trois éléments constituent l'ensemble mobile sur lequel vont s'appliquer les vibrations. The accompanying drawing represents the exterior view and various sections of the knife. It includes: an electric vibrator I embedded in a rear case 2, secured to a front case 3 by any fixing system. Between these two cases comes a spacer 44 A central rod 5 receives at its inner end a counterweight 6 and on the other side the blade 7. These three elements constitute the mobile assembly on which the vibrations will be applied.

Le guidage de l'ensemble mobile s'effectue d'une part entre la tige 5 et l'entretoise 4, d'autre part entre le boîtier avant 3 et la rondelle 8. The mobile assembly is guided on the one hand between the rod 5 and the spacer 4, on the other hand between the front housing 3 and the washer 8.

Aucun mouvement de rotation de l'ensemble mobile ne doit être possible. Le dessin représente une solution préconisée, mais non impérative. La lame 7 et la masselotte 6 étant montées rigidement sur la tige 5, la masselotte 6 sera guidée dans un logement prévu dans l'entretoise 4.No rotational movement of the mobile assembly should be possible. The drawing represents a recommended solution, but not imperative. The blade 7 and the counterweight 6 being rigidly mounted on the rod 5, the counterweight 6 will be guided in a housing provided in the spacer 4.

Il ne peut y avoir vibrations que si la masselotte 6 est maintenue à une certaine distance du vibreur I. Un ressort 9 a été interposé entre la rondelle épaulée 8 et l'entretoise centrale 4, pour maintenir écartée la masselotte. Une butée élastique 10 disposée comme le ressort, destinée à compenser les efforts que l'opérateur va effectuer avec son poignet pour aider à la pénétration.  There can be vibrations only if the counterweight 6 is kept at a certain distance from the vibrator I. A spring 9 has been interposed between the shouldered washer 8 and the central spacer 4, to keep the counterweight apart. An elastic stop 10 arranged like the spring, intended to compensate for the efforts that the operator will make with his wrist to help penetration.

Cette butée empêchera la masselotte de venir se plaquer sur le noyau du vibreur, ce qui supprimerait toute vibration et toute efficacité au couteau. This stop will prevent the flyweight from coming to rest on the core of the vibrator, which would eliminate any vibration and any effectiveness with the knife.

Le ressort 9 et la butée 10 peuvent être confondus en un seul éléjnent.  The spring 9 and the stop 10 can be combined into a single element.

L'arrivée du courant électrique se fera par le cordon Il.  The electric current will arrive via the cord II.

La tension utilisée pourra offrir toute sécurité d'emploi. The voltage used may offer complete security of use.

Un interrupteur 12 peut être placé sur l'enveloppe extérieure mais n'est pas nécessaire au bon fonctionnement du cou- teau. A switch 12 can be placed on the outer casing but is not necessary for the proper functioning of the knife.

La forme du boîtier avant peut être conçue pour assurer une protection de la main de l'opérateur. The shape of the front housing can be designed to provide protection for the operator's hand.

Les figures 4 et 5 donnent un aperçu des formes différentes qui peuvent être données aux lames.  Figures 4 and 5 give an overview of the different shapes that can be given to the blades.
