Abstract
Abstract A collector for the broken-off stems of blind rivets consists of a cylindrical container (20) secured to the rear of the riveting gun head (11). A cylindrical cover (22) closely surrounds the container end and is rotatable around it to a limited extent. The container (20) has an aperture (21), and the cover (22) has a corresponding aperture (23), the cover being biassed by a spring (24) to keep the apertures non-aligned. The cover (22) is rotated by means of a grip (38, 39) to bring the two apertures (21, 23) into alignment to discharge stems from the collector, the aperture (21) being closed automatically by the spring (24) on release of the cover. The container and cover may be of transparent material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
74 words
A collector for broken-off fastener parts produced by the operation of fastener-installation apparatus, which collector comprises; a container attachable to or incorporated in the installation apparatus to receive broken-off fastener parts from the installation apparatus; the container having an aperture; closure means normally overlying and closing the aperture; said closure means being temporarily operable, without detaching the closure means, to allow removal or discharge through the aperture of broken-off parts accumulated in the container.
Claim 2
Dependent Claim
74 words
A collector for broken-off fastener parts produced by the operation of fastener-installation apparatus, which collector comprises; a container attachable to or incorporated in the installation apparatus to receive broken-off fastener parts from the installation apparatus; the container having an aperture; closure means normally overlying and closing the aperture; said closure means being temporarily operable, without detaching the closure means, to allow removal or discharge through the aperture of broken-off parts accumulated in the container.
Claim 3
Dependent Claim
17 words
A collector as claimed in claim 1, wherein the closure means is biassed to close the aperture.
Claim 4
Dependent Claim
20 words
A collector as claimed in claim 1, wherein the closure member is provided with grip means to facilitate operability thereof.
Claim 5
Dependent Claim
18 words
A collector as claimed in claim 1, wherein the closure means is a snap fit on the container.
Claim 6
Dependent Claim
15 words
A collector as claimed in claim 1, wherein the collector is made of transparent material.
Claim 7
Dependent Claim
24 words
A collector as claimed in claim 1, wherein the closure means is operable by relative sliding movement between the closure means and the container.
Claim 8
Dependent Claim
65 words
A collector as claimed in claim 6, wherein the container and the closure means are of generally similar configuration and one is housed within the other, and wherein the closure means is provided with an aperture corresponding to the aperture in the container, the two apertures being normally non-aligned and being brought into alignment by relative sliding movement between the container and the closure member.
Claim 9
Dependent Claim
15 words
A collector as claimed in claim 6, wherein the relative sliding movement comprises rotational movement.
Claim 10
Dependent Claim
31 words
A collector as claimed in claim 6, wherein the container comprises a cylindrical wall in which the aperture is provided, and in which the closure means also comprises a cylindrical wall.
Claim 11
Dependent Claim
63 words
A collector as claimed in claim 6, wherein the container comprises a cylindrical wall in which the aperture is provided, and in which the closure means also comprises a cylindrical wall, the two cylindrical walls being aligned on a common axis, and in which the relative sliding movement comprises relative rotational movement between the container and the closure means about the common axis.
Claim 12
Dependent Claim
48 words
A collector as claimed in claim 10, wherein the orientation of the collector about its cylindrical axis with respect to the installation apparatus is adjustable, thereby to adjust the orientation with respect to the installation apparatus of the container aperture for removal or discharge of broken-off fastener parts.
Claim 13
Dependent Claim
90 words
A collector as claimed in claim 1, wherein: the container is of generally cylindrical configuration and is arranged to receive broken-off fastener parts through one of its ends; the closure means is also of generally cylindrical configuration and closely surrounds the container; the container has its discharge aperture located in its cylindrical wall; and the closure member normally closes the container aperture and has a corresponding aperture in its cylindrical wall, and is operable by rotary movement of the closure means relative to the container to align the two apertures.
Claim 14
Dependent Claim
48 words
A collector as claimed in claim 12, wherein the orientation of the collector about its cylindrical axis with respect to the installation apparatus is adjustable, thereby to adjust the orientation with respect to the installation apparatus of the container aperture for removal or discharge of broken-off fastener parts.
