Abstract:
Apparatus (4) for removing a sealing plug from a bore (11) , which sealing plug comprises an outer sleeve (13) and an inner stem (14) retained within the outer sleeve, the removal taking place after a suitable hole has been drilled part of the way into the stem, which removal apparatus (4) comprises a tapered punch (15) for forcible insertion into the hole in the stem (14) thereby to create an interference fit between the punch (15) and the stem (14) and thereafter driving the stem (14) out of the sleeve (13) whilst also retaining the stem (14) on the punch (15) by virtue of the interference fit, and sleeve-engaging means (16) engagable with the sleeve (13) after the punch (15) has removed the stem (14) from the sleeve (13) , the sleeve-engaging means (16) and the punch (15) being thereafter removable from the bore thereby to remove both the sleeve (13) and the stem (14) from the bore whilst the sleeve (13) and the stem (14) are both retained on the appropriate parts of the apparatus.
Abstract:
A sprinkler riser extractor tool (10) in the form of a screw driver having a head sized to fit the slot (74) of the flow control screw (72) in the nozzle of a sprinkler head (70) and having a sleeve (20) slidably mounted on the shaft (14) of said screw driver formed with a flange (22) adjacent the proximal end of said sleeve to facilitate actuation by the thumb of the operator and having a bushing adjacent the distal end (28) of said sleeve (20) for expanding said distal end when said sleeve is slid forwardly to engage the inside of a sprinkler riser for facilitating lifting of said riser.
Abstract:
A bead crimping tool for crimping a bead element and method for use, wherein the tool includes a base handle, a crush plate member, a pair of opposed pincer members, an actuator handle, and a crush arm member. The bead element is placed on the crush plate and preferably secured in place by the crush arm. Crimping the bead includes squeezing of the actuator handle. During a first portion of such actuation, a cam portion of the actuator handle cases the pincer members to impart a lateral compressive force to a lateral portion of the bead element sufficient to collapse the bead element in a lateral direction. During a subsequent second portion of the single actuation cycle, the crush arm is caused to impart a longitudinal compressive force about a top portion of the bead element sufficient to compress the collapsed bead element in a longitudinal direction.
Abstract:
An impact apparatus, e.g. for moving portions (2, 3) of two elements (4, 5) away from each other by means of a wedge shaped tool (1), which is introduceable between said portions, comprises a carrier (9), to which the tool is attached and which is movable relative to a body (10) of the apparatus. An impact member (11) is also movable relative to the body. A movement transmission device (12) acts between the carrier and a device (13) for activating such force influence on the impact member that it is caused to apply an impact on the carrier. The apparatus is so designed that when the carrier (9) is displaced due to actuation of the tool, the movement of the carrier is transferred via the transmission device to the activating device, which causes force influence on the impact member. The activating device (13) may be a valve for pressure fluid supply.
Abstract:
A tile spacer punch device (10) comprises a rigid elongate body (12) which has a punch element (16) at one end and a grip (18). The punch element (16) has at least three arms (24), each arm (24) is at right angles to an adjacent arm (24). Preferably, the arms (24) intersect and may also be in a common plane. More preferably, four of the said arms (24) are provided. Furthermore, the arms may form part of plates, and the plates may taper inwardly away from the grip.
Abstract:
The invention relates to a device for removing eyelets, especially special steel eyelets, on strips of plastic or fabric. Eyelets on strips of plastic or fabric, e.g. in lorry tarpaulins, become worn with use and generally have a service life that is considerably shorter than the strips of plastic or fabric. As a result it is both usual and economically feasible to replace the worn eyelets with new eyelets in order to take full advantage of the service life of the fabric or plastic strip. Eyelets are generally removed by hand. This is a long, drawn-out process and is not economically worthwhile. The invention provides a device for removing eyelets, especially special steel eyelets, on strips of plastic or fabric, comprising means for compressing the edge of the eyelet towards its centre point or in an opposite direction.
Abstract:
A tool for disassembling an excavation tooth assembly comprising first and second tooth members, the tool comprising: a body comprising a driven portion and first and second legs, the legs extending generally in a common plane and defining an assembly receiving cavity therebetween, each of the first and second legs comprising a wedge portion adjacent the assembly receiving cavity which tapers toward a distal end of the respective legs, in use the tool being adapted to locate over a join defined between the first and second tooth members such that the wedge portion of the first and second legs locates within the join and wherein in use a force applied to the driven portion is arranged to drive the wedge portion further into the join so as to cause separation of the first and second tooth members in a direction transverse to the movement of the first and second legs. A mount for a disassembly tool for an excavation tooth assembly is also disclosed.
Abstract:
The invention relates to a tool (1) for forcing a door comprising: - an elongated shaft (2) having a front end and a rear end; - a handgrip (10) located between the front end and the rear end of the shaft; and - a head (5) fixed to the shaft at the front end thereof, the head having a base part (6) provided with a striking surface (7) on a first side for receiving impacts from a striking tool and a wedge part (8) extending from the base part on the opposite side thereof essentially perpendicularly to the longitudinal axis of the shaft.
Abstract:
A book binding apparatus and method secures pages of a document in a U-shaped channel. The apparatus (20) automatically adjusts its binding jaws (42a, 42b) the current size of the channel (86) prior to the binding force being applied to the channel. Operating forces generated by the apparatus in deforming the channel are limited by generating small amounts of deformation in the channel for each pull of an operating handle (22) to completely secure the pages into the channel. A debinding apparatus (30) and method, using the same operating mechanism as the binding apparatus, debinds the pages from the channel.
