UN TREUIL de ca be s ta n ou de ha la ge a ve tambour spécial à friction permettant d'utiliser des câbles de traction de grande longueur.
Cette invention est schématisée au croquis ci-joint.
Le treuil comporte: - Un tambour de traction n 1 sur lequel on enroule quelques tours du câble de traction n 2. Le treuil est muni sur le même arbre d'un tambour à friction n03 pour l'emmagasinement du câble,
A l'arrière, à distance convenable, il. est prévu une poulie n 4 de retour du câble permettant de passer ce câble entre le
EMI1.1
tambour de traction et 'celui dsemmagasinement n 3.
Le tambour d'emmagasinement n 3 peut être rendu solidaire du tambour de traction par une friction n 5.
Pour le service du treuil, il est fait usage d'un levier n 6 de poussée du tambour d'emmagasinement n 3 contre la friction n 5 réunissant les tambours n 1 et 3; le tambour n 3 se met en mouvement à la vitesse désirée qui par la friction.varie selon les diamètres d'enroulement, tire sur le câble ce qui, par le serrage sur le tambour à friction n 3 donne le mouvement de halage par adhérence au tambour n 1.

RE!1ARQUES: Le tambour dtemmagasinement peut être muni d'un dispositif ordinaire classement du câble entre le tambour et la poulie, mais comme l'effort de traction sur cette partie

est celui de sortie du câble du cabestan, n'est pas très élevé, on peut dans la plupart des cas se dispenser de ce mouvement de classement.
Pour faciliter le déroulement du câble par traction sur celui-ci, lesdeux tambourssont débrayables,

A WINCH of ca be s ta n or ha la ge with special friction drum allowing the use of long traction cables.
This invention is shown schematically in the attached sketch.
The winch comprises: - A traction drum No. 1 on which the traction cable No. 2 is wound a few turns. The winch is fitted on the same shaft with a friction drum No. 3 for storing the cable,
At the rear, at a suitable distance, he. a pulley n 4 is provided for returning the cable allowing this cable to pass between the
EMI1.1
traction drum and storage drum n 3.
The storage drum n 3 can be made integral with the traction drum by a friction n 5.
For the operation of the winch, use is made of a lever n 6 for pushing the storage drum n 3 against the friction n 5 joining the drums n 1 and 3; the drum n 3 starts to move at the desired speed which by friction varies according to the winding diameters, pulls on the cable which, by tightening on the friction drum n 3, gives the hauling movement by adherence to the drum n 1.
EMI1.2
NOTE: The storage drum may be fitted with an ordinary device for classifying the cable between the drum and the pulley, but since the tensile force on this part
<Desc / Clms Page number 2>
is the output of the capstan cable, is not very high, in most cases we can dispense with this classification movement.
To facilitate the unwinding of the cable by pulling on it, the two drums are disengageable,
