Abstract

Improvement to a device for reducing the force for lifting the earth with a spade or the like. The improved device is composed of an arm articulated to the shaft of the tool, about an axis perpendicular to the axis of the shaft. It is carried by a collar in which the shaft rotates. The arm is applied elastically against the shaft when the handle is released. The improvement consists in causing the return of the arm to the front of the tool, the initial position, by means of two torsion springs, or one alone, when the handle of the arm is released whilst the spade has been returned from whichever side.

Description

DESCRIPTION
Dispositif ajouté au brevet n' 84 12948 du 16 août 1984,
Au certificat de première addition n' 84 17354 du 12 novembre 19844
Et au certificat de deuxième addition n' 85 01752 du 6 février 1985,
Pour obtenir le rappel automatique, a l'avant de l'outil, dans sa position initiale, du bras articulé sur le manche.DESCRIPTION
Device added to patent n ° 84 12948 of August 16, 1984,
To the certificate of first addition n ° 84 17354 of November 12, 19844
And to the certificate of second addition n ° 85 01752 of February 6, 1985,
To obtain the automatic recall, at the front of the tool, in its initial position, of the articulated arm on the handle.

En effet lorsque la bêche est retournée pour le renversement de l-a terre dont elle était changée, ce retournement de la bêche étant obtenu par la rotation du manche (t) dans le collier (16) porteur de l'ensemble du bras articulé et du ressort de rappel (3, 7, 10 a 15),
Et que la poignée (2) du bras est alors lachée,
Le ressort déja existant (10 à 14), agissant seul, appliquerait ce bras sur le manche a l'arrière de l'outil, ou latéralement4 d'un côté ou de l'autre, selon que le retournement de la bêche aura été effectue dans un sens ou dans l'autre.When the spade is turned over for the overturning of the earth from which it was changed, this turning over of the spade being obtained by the rotation of the handle (t) in the collar (16) carrying the whole of the articulated arm and the spring recall (3, 7, 10 to 15),
And that the handle (2) of the arm is then released,
The already existing spring (10 to 14), acting alone, would apply this arm to the handle at the rear of the tool, or laterally4 on one side or the other, depending on whether the spade has been turned over. one way or the other.

De sorte qu'il serait nécessaire4 pour poursuivre le labour, de remettre le bras a l'avant de l'outil. position initiale. So it would be necessary4 to continue plowing, to put the arm at the front of the tool. initial position.

Le perfectionnement consiste a utiliser un ou deux ressorts supplémentaires. The improvement consists in using one or two additional springs.

Première solution
1. Un premier ressert de torsion simple(planche unique, Qig. First solution
1. A first simple torsion spring (single plank, Qig.

unique1 18 par exemple) ce ressort travaillant uniquement dans le sens de la réduction du diamètre des spires. est placé pour agir a l'une des extrémités de l'ensemble des deux colliers.unique1 18 for example) this spring working only in the direction of reducing the diameter of the turns. is placed to act at one end of the assembly of the two collars.

L'une des extrémités (19) de ce ressort est solidaire du collier z16) porteur du bras. L'autre extrémité 20) est solidaire de l'autre collier qui est solidaire du manche de l'outil, a l'épaulement (17) de cet autre collier. One end (19) of this spring is secured to the collar z16) carrying the arm. The other end 20) is secured to the other collar which is secured to the handle of the tool, to the shoulder (17) of this other collar.

Ce ressort est détendu lorsque le bras est dans sa position initiale, à l'avant de l'outil. This spring is relaxed when the arm is in its initial position, at the front of the tool.

I1 est tendu par le retournement de la bêche dans un seul sens à droite suivant la figure représentant l'outil à l'avant. I1 is stretched by turning the spade in one direction to the right according to the figure representing the tool at the front.

2. Un second ressort de torsion simple (21), identique au premier, est placé pour agir à l'autre extrémité de l'ensemble des deux colliers. 2. A second simple torsion spring (21), identical to the first, is placed to act at the other end of the set of two collars.

Ses spires sont dans le même sens que celles du premier. Its turns are in the same direction as those of the first.

I1 est également détendu lorsque le bras est dans sa position initiale, en avant de l'outil. I1 is also relaxed when the arm is in its initial position, in front of the tool.

Il est tendu uniquement dans le sens du retournement de la beche du côté opposé à celui provoquant la tension du premier ressort, c'est-a-dire à gauche suivant la figure représentant l'avant de l'outil. It is stretched only in the direction of turning the spout on the side opposite to that causing the tension of the first spring, that is to say on the left according to the figure representing the front of the tool.

Lors du retournement de la bêche dans un sens, le ressort ne travaillant pas est désolidarisé, par l'une de ses extrémites, de l'un des deux colliers, cette extrémité se dégageant d'une butée qui provoque sa tension dans l'autre sens. When the spade is turned over in one direction, the non-working spring is separated, by one of its ends, from one of the two collars, this end emerging from a stop which causes its tension in the other meaning.

Les deux ressorts peuvent n'en former qu'un seul, qui est solidaire en son milieu, du collier t16) porteur du bras, et dont chacune des deux extrémités est solidaire d'un des deux épaulements (17) du collier lui-meme solidaire du manche de l'outil, par une butée. La butée de l'une des deux extrémité du ressort provoquant la tension, alors que l'autre des deux extrémités du ressort se degage de la sienne. The two springs can form only one, which is secured in the middle of the collar t16) carrying the arm, and each of the two ends of which is secured to one of the two shoulders (17) of the collar itself secured to the handle of the tool, by a stop. The stop of one of the two ends of the spring causing tension, while the other of the two ends of the spring emerges from its own.

Deuxième solution
Un ressort de torsion unique, semblable à l'un ou l'autre des deux essorts ci-dessus, mais travaillant dans les deux sens, c'est-à-dire tant dans le sens de la réduction du diamètre des spires, que dans le sens de l'augmentation de ce diamètre ;
Solidaire, à l'une de ses deux extrémités, du collier S16) porteur du bras, et, à l'autre de ses deux exprémités, du collier (17) solidaire du manche,
Il est détendu lorsque le bras est dans la position initiale, en avant de l'outil.Second solution
A single torsion spring, similar to one or the other of the two above springs, but working in both directions, that is to say both in the direction of reducing the diameter of the turns, as in the direction of the increase in this diameter;
Solid, at one of its two ends, the collar S16) carrying the arm, and, at the other of its two ends, the collar (17) solid with the handle,
It is relaxed when the arm is in the initial position, in front of the tool.

De sorte que cet unique ressort effectue le rappel automatique du bras avec le collier porteur, de quelque côté que soit effectué le retournement de la beche. So that this single spring carries out the automatic return of the arm with the support collar, regardless of which side the flipper is turned over.

L'action de ce ressort de torsion peut être renforcée par celle d'un ressort identique placé a l'autre extrémité de l'ensemble des deux colliers (16 et et 17) et dont les spires sont dans le meme sens ou en sens inverse des siennes. The action of this torsion spring can be reinforced by that of an identical spring placed at the other end of the set of two collars (16 and 17) and whose turns are in the same direction or in opposite directions his own.

Pour assurer exactement la détente de chacun des deux ressorts, ou du ressort unique, lorsque le bras est à l'avant de l'outil, l'ancrage de chacun des deux ressorts, ou du ressort unique, sur le périmètre de l'un des colliers est réglable, par exemple par le coulissement de l'extrémité du ressort dans un oeil solidaire du collier et dans lequel le ressort est bloque par une vis lorsque le bras est dans sa position initiale, à l'avant de l'outil.  To ensure exact relaxation of each of the two springs, or of the single spring, when the arm is at the front of the tool, the anchoring of each of the two springs, or of the single spring, on the perimeter of one collars is adjustable, for example by sliding the end of the spring in an eye secured to the collar and in which the spring is blocked by a screw when the arm is in its initial position, at the front of the tool.
