Dec. 15, 1964 R. LEFEBVRE APPARATUS FOR APPLYING CLIPS 2 Sheets-*Sheet 1 Filed Jan. 14, 1963 l INuEmag M MME B-rraAA/sy Dec. 15, 1964 R. LEFEBVRE 3,160,890

APPARATUS Foa APPLYING cLIPs Filed Jan. 14, 1963 2 Sheets-Sheet 2 Afr ro hlm United States Patent z claims. (Cl. 1-1s7) The present invention is concerned with an apparatus for applying clips and, more particularly, clips which are in the form of a wire bent to the shape of a C, which is closed about the neck of a bag, flexible container or any other article, in order to close the said bag or the like.

Such apparatus generally comprises jaws pivotably mounted on a slide which is capable ofk sliding in front of a charging device containing a stack of clips. In the condition of rest, the jaws are situated slightly to the rear of the stack, an open clip being situated between them. When the apparatus is brought into action the said jaws advance, bring the clip into the application position, closing on the clip to clamp it labout the neck of the bag, and then withdraw to take up the position of rest once more, taking a fresh clip from the stack contained in the charging device.

According to the present invention, the apparatus is so arranged that in the condition of rest the jaws occupy an advanced position, are opened `and hold between themselves a clip ready for application. As soon as the apparatus is brought into action, the jaws close, apply the clip, withdraw to taire a fresh clip from the stack contained in the charging of rest again.

By means of this apparatus, clips can be applied with very Agreat accuracy since the lclip ready to be `applied can be placed directly at the place where it is to be fixed and, apart from the jaw closing movement, all the movements of the mobile parts of the apparatus are carried out when the clip has been applied.

The apparatus is preferably constructed in the form of a pistol which is very easily handled Iand is pneumatically operated and permits of obtaining a high rate of operation which may be as much as 100 Kstrokes per minute.

The invention is illustrated by way of example in the accompanying drawings, in which:

FIGURE 1 is a longitudinal sectional view of an apparatus according to the invention;

FIGURE 2 is a plan view in section on II-II of FIG- URE l, and

FiGURE 3 is a view of a clip which can be applied by means of this apparatus.

In lthe construction shown in the drawings, the apparatus comprises la butt 1 to the grip of which there is connected,

a pipe socket 2 for connection to a compressed-air supply pipe 3. The pipe socket 2 is followed by a duct 4 debouching into a chamber 5 in which is accommodated a valve 6 controlled by means of a push button 7. The valve 6 makes it possible to allow the duct 4 to communicate with another duct S which terminates at the rear end of a cylinder 9 arranged in the butt 1.

Mounted in the cylinder 9 is apiston 10 .whose rear face carries a boss 11 and which comprises externally a toroidal sealing ring 12 mounted in a groove 13.

The piston is formed with ya stepped cavity 14 against the larger step of which there bears the end of a compression spring 15 which tends to push the piston 10 p towards the rear of the' butt. At the opposite end, the spring 15 abuts on a centering ring 16 provided with a circular groove 17. The ring 16 is screwed into the tapped mouth 18 of the butt 1, the said mouth being split and provided with a locking screw 19.

device, and then take up the position 3,160,890 VVliatented Dec. 15, 1964 ICC Screwed into the middle step of the piston 10 is an attaching sleeve 20 which abuts on a washer 21 and into which is extended the end of a rod 23 which a compression spring 24 tends to move outwardly. This spring bears at one end against an abutment element 25 arranged at the end of the cavity 14 and at the other end on the body 26 of the rod 23. The iiront portion of the bore of the sleeve 2i) has a sufficient diameter to enable the body 26 of the rod to be capable of penetrating therein and it is formed with a groove 27 intended'to co-operate with a hook 28 of a lever 29 which is mounted in the slot 30 of the body 26, pivotally mounted on a transverse pin 31 and urged into contact with the bottom a of the slot by means of a spring 32.

The body 26 of the rod 23 issues from lthe butt through a bearing 33 screwed into the ring 16 and locked by means 1 of countersunk screws 34. The bore of this bearing has a bevelied portion 35 which is adapted to co-operate with yan oblique ramp 36 on the lever 29 to cause the lever to pivot in opposition to the action of the spring 32.

A plate 3S is screwed to the bearing 33 and locked thereto by means of a screw 37, and along the said plate the body 26 of the rod 23 (FIGURE 2) is adapted to be displaced. Provided onl the outer end of this body are two links 39 pivotally mounted within a'bifurcation 26a of Y 'the rod on a pin 40, and a tension spring 41 attached to pins 42 tends to return the said links towards one another. Pivotally mounted on the end of the 1inks-39 are jaws 43, 44 comprising curved grooves 43a or 44a adapted to receive a clip 61 for application. The jaws have mating thinner ledges or auges 43 and 44', respectively, which pivot on a pin 45 carried by a slide 46 which is adapted to slide on Vthe plate 3S. The slide 46 has a guide heel 47 engaged in a slot 48 in the plate 38 (FIGURE 2). It is held in position by a strip 49 fixed by means of screws Si). j

The plate 38 terminates at the front end ina bevelled Y nose 51 rearwardly of which there is provided an aperture 52 in the form of a trapezium with the rear angles rounded. Into this aperture there can fit the end of the channel 53 of a charging device 54 adapted to receive theclips which areto be applied by means of the apparatus.- This charging device comprises a pushmember 55 sliding both in the channel and on a rod 56 carrying ia long com- The apparatus which has just been described operates in the following manner:

In the condition of rest, the mobile mechanism of the apparatus occupies the'position shown in FIGURE 1.

The Vjaws 43, 44 are advanced and open. They contain between their noses, within the grooves 43a, 44a, a clip 61, `and the first clip 61a ofthe stack contained in the charging device 54 bears against their central portion.

When pressure is applied to the push button 7 of the .valve 6, the compressed air admitted into, the duct 8 repels the piston 10 which ladvances,loading the spring l 15 and urging the rod 23 forwardly, which causes the jaws f 43, 44 to be closed and brings about the application of the @11961. FIGURE 1 shows the jaw 43 'provided with a small indentation 43b adapted to allow the passage of the point 62 or 63 of the clipwhen the said clip is closed.V Furthermore, the spring 24 is compressed and Vthe sleeve 20 by means of its groove 27 attaches itelfy to the nose 2S ofthelever29-` w When the push button 7 is released, the valve 6 closes 9 e? the communication between the ducts 4 and 8, making the duct S communicate with the free atmosphere owing to 4the clearance provided Vabout the stern of the push button.Y Owing to'this fact, the'pistontlis moved Yrearwardly by the spring 15. Firstof all it brings'with it the rod 23, 26, which causes the re-'openingv of the jaws 43, 44 and the withdrawalof these togetherl with the slide de; This withdrawal is suiicient for the noses of the jaws` to move into a position rearwardly of: the aperture 52 of the plate 3S, which permits a new clip to be inserted between the jaws, which have indentations'da and 44a adapted to receive such -a clip.v Y

The withdrawal ofthe rod 23 continues until the ramp of the lever 29 cornes intoscontact with the bevelledsurface 35 of the bearing 33.' The tooth 28 is then disengaged from the groove 27 and the rod 23, 26 is returned forwardly by the spring 24, which ensures the shifting fY the jaws and ofthe clipA to the end 51 of theplate without,

however, causing the jaws to close on the clip. YThe apparatus is ready to be used for a fresh application operation. v t Y 1.
