La charrue 1 representee. (fig. 1 et 2) est une charrue reversible. 0n lui a fixe une fourche d'attelage 2 dopt chaque extremite vient s'articuler en 3 ä une bielle double de tirage 4 (fig. 3) elle-meme articulee en 5 ä une tige 6 traversant librement une oreille 7 fixee au tracteur $ et portant, de pari et d'autre de celle-ci, deux butees 9 et 10 contra lesquelles butent des ressorts 11 et 12 pre- nant appui sur Foreille 7. Plow 1 represented. (fig. 1 and 2) is a reversible plough. A coupling fork 2 has been attached to it, each end of which is articulated at 3 to a double draw rod 4 (fig. 3) itself articulated at 5 to a rod 6 passing freely through an ear 7 fixed to the tractor $ and carrying, on either side of it, two abutments 9 and 10 against which abut springs 11 and 12 resting on Foreille 7.

Au tracteur 8 est encore fixee une Pla- que 13 se prolongeant verticaIement vers la bas entre las deux e16ments paralleles de la bielle de tirage 4 et munie dune fenetre al- long6e 14 Jans laquelle joue librement un goujon 15 fixe aux deux elements de la bielle 4. To the tractor 8 is still fixed a Plate 13 extending vertically downwards between the two parallel elements of the draw rod 4 and provided with an elongated window 14 Jans which plays freely a stud 15 fixed to the two elements of the connecting rod 4.

La bielle 4 se releve vers la haut ä Far- riere pour venir porter une noix articulee 16 dans laquelle peut pivoter une vis 17 terminee par un volant de manoeuvre 18 et se vissant Jans un ecrou 19 port6 ä articula- tion par la Plaque 13. Connecting rod 4 rises upwards at the rear to carry an articulated nut 16 in which can pivot a screw 17 terminated by a maneuvering wheel 18 and screwed into a nut 19 carried by articulation by plate 13.

A la charrue est articule un manchon 20 dans lequel peut coulisser une bielle de re devage 21 terminee par un ressort de com- pression 22 la reliant elastiquement au man- chon 20. Cette bielle se termine par une cre- maillere 23 et une poign6e de manoeuvre 25. La cremaillere 23 (fig. 4 ä 6) Porte une rai- nure 26 dans Iaquelle passe un teton 27 fixe ä 1'extr6mite d'un bras 28 .articule en 29 sur la tracteur et rappele par un ressort 30 con tra une butee 31. The plow is articulated with a sleeve 20 in which can slide a devage connecting rod 21 terminated by a compression spring 22 elastically connecting it to the sleeve 20. This connecting rod terminates with a rack 23 and a handle of maneuver 25. The rack 23 (fig. 4 to 6) carries a groove 26 in which passes a stud 27 fixed at the end of an arm 28 articulated at 29 on the tractor and recalled by a spring 30 against a stop 31.

A I'extremite arriere de la rainure 26 se trouve une encoche 32 destinee ä recevoir la teton 27 comme il sera explique ci- apr6s. At the rear end of the groove 26 is a notch 32 intended to receive the stud 27 as will be explained below.

La traoteur, sur lequel an a suppos6 la dis- positif monte, Porte une Prise de mouvement disposee en baut de Farbre de transmission. 0n y fixe un baut d'arbre 33 portant une vis saus fin 34 commandant un pignon 35 cale sur un arbre 36 (fig. 6) pört6 par des montants 37 fixes ä 1'arriere du tracteur. L'arbre 36 Porte un pignon ä Gage d'ecu- reuil 38 dispose de fagon ä, pouvoir venir engrener avec la cremaillere 23 quand celIe-ei est abaissee (fig. 4, Position en traits inter- rompus). The tractor, on which it is assumed the device is mounted, carries a power take-off placed at the end of the transmission shaft. 0n fixed there a shaft 33 carrying a screw without end 34 controlling a pinion 35 wedged on a shaft 36 (fig. 6) pört6 by uprights 37 fixed to the rear of the tractor. The shaft 36 carries a squirrel pinion 38 arranged in such a way as to be able to mesh with the rack 23 when the rack 23 is lowered (FIG. 4, Position in broken lines).

La fonehonnement est la suivant: La charrue, supposee reposant sur la sol, est tiree par la fourche d'attelage 2, las bielles 4 et las tiges 6 prenant appui sur las oreilles 7 par Ips ressorts 11. L'ensemble des ressorts 11 et 12 assure une grande dou- -ceur dans :1a liaison et evite las ä :coups. Les goujons 15 assurent 1e- guidage des bielles 4. Quant ä, la profondeur d'enfoncement de la charrue Jans la sol, alle est reglee par la volant 18 qui 61eve au abaisse las points d'articulation 3. The operation is as follows: The plow, assumed to be resting on the ground, is pulled by the coupling fork 2, the connecting rods 4 and the rods 6 resting on the lugs 7 by Ips springs 11. All the springs 11 and 12 ensures great softness in: 1a connection and avoids las ä: blows. The studs 15 ensure the first guide of the connecting rods 4. As for the depth of penetration of the plow Jans the ground, alle is regulated by the steering wheel 18 which 61eve lowers the points of articulation 3.

Quand an veut relever la cha.rrue, an abaisse la lavier 25, ce qui amene la cr6mail- lere 23 en Prise .arec la pignon 38 (fig. 4, Po sition en traits interrompus). Ce dernier RTI ID="0002.0272" WI="5" HE="4" LX="1904" LY="904"> en- traine celle-ei, tirant ainsi la bielle 21 qui, par la ressort 22, souleve la charrue jus- qu'ä. 1'amener ä la Position de la fig. 1. When an wants to raise the plow, an lowers the lavier 25, which brings the rack 23 into engagement with the pinion 38 (fig. 4, Position in broken lines). This last RTI ID="0002.0272" WI="5" HE="4" LX="1904" LY="904"> drives this one, thus pulling the connecting rod 21 which, by the spring 22, raises the plow up to. bring it to the position of fig. 1.

Des que la cremaillere 23 est venue en Prise aveo la pignon 38, il est inutile & main- tenir la lavier 25 abaisse, car las dents ;de la cr6maillere out, comme montre, une forme nette ment inclinee, de teile sorte qu'elles ap- puient ladite eremai11ere,contra 1e pignon. As soon as the rack 23 has come into engagement with the pinion 38, it is useless to keep the lever 25 lowered, because the teeth of the rack have, as shown, a distinctly inclined shape. , so that they support the said shoe, against the pinion.

En fin de denture, la cremaillere est li- beree, mais la goujon 27 est venu ;dans 1'en- coche 32, comme montr6 fig. 5, et 1a ahar- rne ne peut retomber, la lavier 2:8 mainte- nant ainsi la bielle 21. At the end of the toothing, the rack is free, but the pin 27 has come into the notch 32, as shown in fig. 5, and the aharme cannot fall, the lavier 2:8 thus maintaining the connecting rod 21.

Daus cette Position (fig. 2), la ressort 22 sert d'amortisseur pour a#bsarber las -ehoes ;dus aux cahots de la raute et eviter las ef- forts anormnaux. In this position (fig. 2), the spring 22 acts as a shock absorber to a#bsarber the -ehoes; due to the bumps of the road and avoid the abnormal efforts.

Quand an veut faire retomber 1a charrue sur Je sol, il suffit de soulever la lavier 25 pour degager la goujon 27. When you want the plow to fall back on the ground, you just have to lift the plate 25 to disengage the pin 27.

0n notera que toutes ces @mano#,uvres peu- vent etre effeetuees par la conducteur du tracteur, saus quitter son siege. It should be noted that all these @mano#,works can be carried out by the driver of the tractor, without leaving his seat.

Daus certains tracteurs, et notamment Jans la tracteur Fordson, 1'arbre de trans- mission est place tres bas. Daus üe -cas, an utilise la ;dispositif represente .schematique- ment par las fig. 7 et B. La pignon 38 est cale sur un arbrü 39 parallele ä 1'arbre 36 In some tractors, notably the Fordson tractor, the transmission shaft is placed very low. Daus üe -case, an uses the device represented .schematiquement by the fig. 7 and B. Pinion 38 is wedged on shaft 39 parallel to shaft 36

de la raue de vis saus fin 35, et les deux ar bres 39 et 36 sont relies 1'un ä lautre par les roues @de chaine 40 et 41 et la chaine 40a. of the endless screw chain 35, and the two shafts 39 and 36 are connected to each other by the chain wheels 40 and 41 and the chain 40a.

Le fonctionnement reste 1e meme. Operation remains the same.

Les fix. 9 ä 12 montrent une variante d'execution destinee ä rendre plus douce la manceuvre du relevage. Fixes. 9 to 12 show a variant of execution intended to make the operation of the lift more gentle.

La bielle 21 s'articule ä un bras 43 cale sur un arbre augiliaire 42 portant un second bras 44 -sur lequel est articulee 1e cr6mail lere 23. La rainure 26 ne Porte plus aucune encoche et 1e goujon 27 est Porte par un le vier 47 articule en 48 sur un support fixe au tnacteur; un ressort 49 tend sans cesse ä rap peler 1e levier 47 ä 1.a Position des fix. 9 et 11 pour lesquelles la crdmaillere 23 est eloi gn6e du pignon de comm.ande 38. The connecting rod 21 is articulated to an arm 43 wedged on an auxiliary shaft 42 carrying a second arm 44 -on which is articulated the first rack 23. The groove 26 no longer carries any notch and the first pin 27 is carried by a lever 47 articulated at 48 on a support fixed to the tnacteur; a spring 49 constantly tends to recall the first lever 47 to 1.a Position of the fixings. 9 and 11 for which the rack 23 is remote from the control pinion 38.

L'arbre 42 Porte un secteur 50 portant sur san Bord radial superieur une encocbe 51. Ün levier 52, pivote en 53 sur un mon tant 37 Porte un doigt 54 qui, traversant li brement une fenetre 55 du montant 37, vient appuyer contre la Peripherie du secteur 50 sous 1'action d'un ressort agissant sur 1e le vier 52. The shaft 42 carries a sector 50 bearing on its upper radial edge a notch 51. A lever 52, pivots at 53 on a post 37 carries a finger 54 which, freely crossing a window 55 of the post 37, presses against the Periphery of sector 50 under the action of a spring acting on the shaft 52.

La charrue dtant ä sa Position hasse (Po sition des organes sur la fix. 11), si 1'on tourne 1e levier 47 pour 1'amener ä la Posi tion de la fix. 12, 1.a cremaillere 23 vient en Prise avec 1e pignon 38 qui 1'entraine, deter minant ainsi la traction @de la bielle 21 et le levage de la charrne. Comme daus la Pre miere forme d'exdcution, en fin de denture, la cremaillere dchappe (fix. 9). Mais ä ce moment, 1e Joigt 54 a d6passe 1e bord supe rieur du secteur 50 et, lorsque celui-ci tend ä revenir en arriere sous 1'action du poids de la charrue, ledit doigt vient se loger dans 1'en.coche 51, maintenant les pieces ä la posi t.ion haute de la, charrue (fix. 9 et 10). Since the plow is in its raised position (Position of the organs on the attachment 11), if the lever 47 is turned to bring it to the Position of the attachment. 12, 1.a rack 23 comes into engagement with the first pinion 38 which drives it, thus determining the traction @of the connecting rod 21 and the lifting of the charrne. As in the first form of execution, at the end of the toothing, the rack slips out (fix. 9). But at this moment, the joint 54 has exceeded the upper edge of the sector 50 and, when the latter tends to come back under the action of the weight of the plough, the said finger comes to lodge in the notch 51 , keeping the pieces in the high position of the plow (fix. 9 and 10).

Pour abaisser la charrue, il suffit,de ma nceuvrer le levier 52 pour degager 1e doigt 54. To lower the plow, it is enough for me to operate the lever 52 to disengage the first finger 54.
