Abstract:
A plug for operatively connecting an extremity of a torsion spring to another corresponding component of a counterbalancing assembly. The plug includes a collar and at least one connecting flange. The collar defines a longitudinal axis, and includes first and second opposite ends, the collar being shaped and sized for removably mounting onto the extremity of the torsion spring. Each connecting flange is provided on the first end of the collar for connecting the plug onto the corresponding component of the counterbalancing assembly. The improvement lies in that the collar has first and second sections, the first section being adjacent to the first end of the collar and having a peripheral surface being provided with threading for threadedly engaging the extremity of the torsion spring, and the second section being adjacent to the second end of the collar and having a peripheral surface being tapered with respect to the peripheral surface of the first section so as to minimize interference with an internal portion of the torsion spring when the collar is removably mounted onto the extremity of the torsion spring.
Abstract:
A frontward blade mounting bracket, for connecting the front end of a side blade to a vehicle side adjacent a road surface, includes a spacer and an elongate guide member. The spacer has opposed first and second spacer ends. The first spacer end is pivotally connected to the vehicle side about a substantially vertical pivot axis, and the second spacer end is spaced apart from the first spacer end in a direction leading outwardly away from the vehicle side. The guide member has first and second guide parts connected to the second spacer end and the second guide part respectively. The first and second guide parts longitudinally move relative to one another about a substantially vertical guide axis.
Abstract:
A plug for use in a counterbalancing mechanism of a cable-operated door. The plug is used for operatively connecting an overhead shaft to a torsion spring co-axially mounted thereon. The plug includes a cylindrical collar and a cylindrical flange. The cylindrical collar has opposite first and second portions and is provided with a hooking slot for hooking a free end of the torsion spring thereon, and the torsion spring having a segment coaxially mounted about the first portion of the collar. The cylindrical flange is rigidly affixed to the second portion of the collar and is used for transferring a torque between the torsion spring and the overhead shaft when the flange is securely fixed about the overhead shaft. The plug is characterized in that the collar is eccentrically mounted about the overhead shaft, thereby allowing the plug to be used when the radial space between the plug and the overhead shaft is limited and also preventing the overhead shaft from being damaged by the free end of the torsion spring.
Abstract:
A spreading device for confined application of grain type materials along a well-defined path on a road from a conveyor of a storing tank mounted on a moving vehicle includes a chute member mounted thereon that receives the materials from the conveyor and substantially drops them generally vertically under gravity on the road along the path in proximity and in front of a roller. The latter stops the materials relative to the road and confines, or packs, them on the road. The spreading device is adapted to be mounted on either side of the vehicle, in line with its wheels.
Abstract:
An attachment device attaches adjacent first and second concrete pieces to one another along corresponding first and second interfacing side surfaces thereof, thereby forming a concrete piece attachment arrangement. The device includes an elongate base member having opposed first and second portions, and first and second lateral members securing to and respectively extending substantially perpendicularly from first and second ends of the base member. The first and second portions of the base member extend within first and second recesses respectively formed into the concrete pieces, in a direction generally perpendicular to the first and second interfacing side surfaces. The first and second lateral member respectively extend through bore holes extending through the first and second concrete pieces and connecting with the respective first and second recesses. A method for attaching the concrete pieces to one another with an attachment piece is also described.
Abstract:
A ratchet system for winding a rolling door assembly. The ratchet system includes a support bracket, a cam, and a biasing device. The support bracket is preferably mounted onto a fixed structure of the rolling door assembly. The cam is pivotally mounted about the support bracket and positioned adjacent to a portion of an overhead shaft of the assembly. The cam is shaped and sized to cooperate with this portion of the overhead shaft between a first position, where the cam allows rotation of the overhead shaft along a first direction, and a second position, where the cam has a surface engaged with the overhead shaft and where further rotation of the overhead shaft along a second direction, opposite to the first direction, is blocked by the cam. The biasing device is used for urging the surface of the cam onto the overhead shaft. The ratchet system is particularly useful for adjustably controlling the rotation of the overhead shaft of the rolling door assembly during the winding thereof.
Abstract:
A system for forming a cementitious structure of cementitious material on a ground surface is provided. The system consists of at least one pair of moulds, each mould having at least one pathway disposed thereon, and at least one brace having two spikes connected to one another by a connecting member. The spikes are inserted into the pathways to space the moulds apart, via the connecting member, in fixed spatial relationship and then into the ground surface to anchor the moulds thereto. The cementitious material is then poured between the moulds to form the cementitious structure. Optionally, the spikes may be connected to the connecting member by inserting of spikes into tubes connected to the connecting member, the tubes being insertable into pathways and the spikes subsequently inserted therethrough to insert the spikes through the pathway and into the ground surface.
Abstract:
A mounting for a side wing plough includes a mounting having two relatively movable sectorially formed elements, one of which being fixed to the plough and the other being connected to a lifting means for the leading end of the plough. The two elements register with one another and are guided thereby, the interengagement of the elements constituting the connection enabling movement of the plough and also permitting limited compensatory shifting of the plough upon encountering an immovable obstacle. The mounting could further include a tilt mechanism of limited stroke affording the capability of the plough to tilt toward the vehicle to accommodate unpredictable movement of the plough upon impacting an immovable obstacle.

A frontward blade mounting bracket, for connecting the front end of a side blade to a vehicle side adjacent a road surface, includes a spacer and an elongate guide member. The spacer has opposed first and second spacer ends. The first spacer end is pivotally connected to the vehicle side about a substantially vertical pivot axis, and the second spacer end is spaced apart from the first spacer end in a direction leading outwardly away from the vehicle side. The guide member has first and second guide parts connected to the second spacer end and the second guide part respectively. The first and second guide parts longitudinally move relative to one another about a substantially vertical guide axis.
Abstract:
A window framework for mounting a glass pane in an aperture of a panel. The window framework includes an exterior frame having a peripheral wall shaped for fitting with and extending into the aperture. The peripheral wall extends between exterior and interior sides of the panel, and is provided along the periphery thereof with an abutment member adjacent to the exterior side. The wall is also provided with stop means adjacent to the interior side. The window framework also includes removable locking means having a flexible element lockable with the stop means when the locking means is in a locking position. The locking means is also provided with an element for holding the glass pane in position with the aid of the abutment member when the locking means is in the locking position. The window framework further includes a securing means for securing the exterior frame to the panel in the aperture. A method for mounting a glass pane in an aperture of a panel is also provided.
