Applicator as defined in claim 1, wherein a slider (35) is mounted for displacement in the magazine (8), the slider resting resiliently against the scalp clips (53) in the magazine (8) under the influence of the urging means (37) and pushing the scalp clips towards the open end.

Claim 11

Applicator as defined in claim 9, wherein the slider (35) is adapted to be secured in its retracted position.

Claim 12

Applicator as defined in claim 9, wherein the urging means is a spiral spring (37) located in the interior of the slider (35), the free end (38) of the coil spring being secured to the magazine (8) near the open end thereof.

Claim 13

Applicator as defined in claim 11, wherein the spiral spring is designed as a leaf spring (37) abutting on one wall of the magazine (8) adjacent the scalp clips (53).

Claim 14

Applicator for C-shaped clips which have two legs joined by a bridge and facing clamping jaws at their free ends, rearwardly projecting application surfaces at the regions where the legs and bridge meet, and laterally projecting edge regions adjoining the application surfaces, comprising two applying instruments movable between first and second positions positioned to engage the application surfaces of a scalp clip and displace them towards one another for opening said scalp clip, a magazine that holds a plurality of scalp clips arranged one behind the other in the magazine with the free ends of one scalp clip resting against the bridge of the adjacent scalp clip, said magazine being open at the end to which the free ends of the legs of the scalp clips point, and guiding the scalp clips in the magazine for displacement in the longitudinal direction thereof, spring means for moving the scalp clips towards the open end of the magazine, said applying instruments, in the first position being remote from one another, projecting downwardly and upwardly into the feed path of the scalp clips at said open end such that one of said scalp clips moved by said urging means past said applying instruments abuts thereon with said laterally projecting edge regions adjoining the application surfaces and in the second position being closer together with said instruments abutting on the application surfaces of one of said scalp clips held between them and thereby opening said one scalp clip, and, a retaining element dipping into and being displaceable out of the feed path of the scalp clips, said retaining element also being disposed before the applying instruments by approximately the length of a scalp clip and retaining that clip which follows directly behind the scalp clip gripped by the applying instruments.

Claim 15

Applicator for C-shaped clips which have two legs joined by a bridge and facing clamping jaws at their free ends, rearwardly projecting application surfaces at the regions where the legs and bridge meet, and laterally projecting edge regions adjoining the application surfaces, comprising two applying instruments movable between first and second positions positioned to engage the application surfaces of a scalp clip and displace them towards one another for opening said scalp clip, a magazine that holds a plurality of scalp clips arranged one behind the other in the magazine with the free ends of one scalp clip resting against the bridge of the adjacent scalp clip, said magazine being open at the end to which the free ends of the legs of the scalp clips point, and guiding the scalp clips in the magazine for displacement in the longitudinal direction thereof, spring means for moving the scalp clips towards the open end of the magazine, said applying instruments, in the first position being remote from one another, projecting downwardly and upwardly into the feed path of the scalp clips at said open end such that one of said scalp clips moved by said urging means past said applying instruments abuts thereon with said laterally projecting edge regions adjoining the application surfaces and in the second position being closer together with said instruments abutting on the application surfaces of one of said scalp clips held between them and thereby opening said one scalp clip, and, a retaining element dipping into and being displaceable out of the feed path of the scalp clips, said retaining element also being disposed before the applying instruments by approximately the length of a scalp clip and retaining that clip which follows directly behind the scalp clip gripped by the applying instruments.

Claim 16

Applicator as defined in claim 13, wherein the retaining element (129, 130) is adapted to be displaceable simultaneously with the applying instruments such that it is withdrawn from the feed path when the applying instruments are in their second position (applying position) whereas it dips into the feed path when the applying instruments are in their first position (inoperative position).
