Abstract

The tool comprises a screw-jack and is used both to compress a coil spring and to facilitate its installation. It comprises an axle rod (1) with left and right hand screw threads on its respective ends (1a,1b), being fitted with a ring with blind holes (2) for engagement by a tool eng. a tommy bar at an intermediate point. A sleeve (3a,3b) with the corresponding internal screw thread is mounted on each end, being furnished with the brackets (4a,4b) for holding the ends of the subject spring in position. The curved brackets have internally projecting lugs (5,6).

Description

La présente invention se rapporte a un dispositif destiné a comprimer des ressorts de compression pour faciliter leur mise en place. The present invention relates to a device intended to compress compression springs to facilitate their positioning.

L'un des buts de l'invention est de réaliser un appareil simple, peu onéreux d'une utilisation très aisée et qui offre une grande sureté d'emploi. One of the aims of the invention is to produce a simple device, inexpensive to use very easily and which offers great safety in use.

Le compresseur selon l'invention est caractérisé en ce qu'il est constitué d'une tige comportant en un point intermédiaire de sa longueur des moyens pour la prise d'un outil, l'une des extrémité de la tige comportant un filetage de pas a droite, tandis que l'autre est pourvu d'un filetage de pas R gauche, l'une desdites extrémités coopérant avec un manchon pourvu d'un taraudage correspondant tandis que l'autre extrémité coopére avec un manchon également pourvu d'un taraudage correspondant, chacun des manchons étant pourvu de moyens pour le maintien des extrémités correspondantes du ressort S comprimer
Suivant une caractéristique constructive les moyens de maintien des extrémités du ressort sont constitués par des arceaux dont la surface interne est pourvue de griffes. The compressor according to the invention is characterized in that it consists of a rod comprising at an intermediate point of its length means for gripping a tool, one of the ends of the rod comprising a pitch thread on the right, while the other is provided with a left-hand pitch thread R, one of said ends cooperating with a sleeve provided with a corresponding thread while the other end cooperates with a sleeve also provided with a thread corresponding, each of the sleeves being provided with means for holding the corresponding ends of the spring S compress
According to a constructive characteristic, the means for holding the ends of the spring consist of hoops, the internal surface of which is provided with claws.

L'invention va maintenant etre décrite avec plus de détails en se référant S un mode de réalisation particulier donné S titre d'exemple seulement et représenté aux dessins annexés. The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings.

Fig. 1 est une vue en élévation d'un compresseur selon l'invention. Fig. 1 is an elevational view of a compressor according to the invention.

Fig.2 est une vue en plan du compresseur de la figure 1.  Fig.2 is a plan view of the compressor of Figure 1.

Le compresseur, représenté aux figures est constitué d'une tige 1 qui comporte en un point intermédiaire médian de sa longueur une bague 2 pourvue de trous borgnes radiaux pour recevoir un outil tel qu'une broche pour faire tourner la tige 1. The compressor, shown in the figures, consists of a rod 1 which comprises, at a median intermediate point of its length, a ring 2 provided with radial blind holes for receiving a tool such as a spindle for rotating the rod 1.

La partie la de la tige 1 comporte un filetage tandis que la partie lb est pourvue d'un filetage de pas contraire. The part 1a of the rod 1 has a thread while the part 1b is provided with a thread of opposite pitch.

La partie la est destinée S coopérer avec un taraudage correspondant d'un manchon 3a solidaire d'un arceau 4a,
La partie ib coopère avec un manchon 3b solidaire d'un arceau 4b.The part 1a is intended to cooperate with a corresponding tapping of a sleeve 3a secured to a hoop 4a,
The part ib cooperates with a sleeve 3b secured to a hoop 4b.

Les arceaux a et 4b comportent des griffes 5 et 6 de retenue des extrémités du ressort ! comprimer. The arches a and 4b have claws 5 and 6 for retaining the ends of the spring! compress.

Pour comprimer un ressort on l'introduit entre les arceaux 4a- 4b afin que ses extrémités coopèrent avec les griffes 5 et 6 et en agissant sur la bague 2 on taist tourner la tige 1 de manière a rapprocher l'un de l'autre lesdits arceaux 4a- 4b. To compress a spring we introduce it between the arches 4a- 4b so that its ends cooperate with the claws 5 and 6 and by acting on the ring 2 we taist turn the rod 1 so as to bring the said one closer to each other hoops 4a- 4b.

Bien entendu, l'invention n'est pas limitée au mode de realisation qui vient d'être décrit, et qui a été présenté. On pourra y apporter de nombreuses modifications de détails, sans pour cela, sortir du cadre de l'invention.  Of course, the invention is not limited to the embodiment which has just been described, and which has been presented. Many modifications of details can be made therein without departing from the scope of the invention.
