Description
Patent of Addition for Tubular steel Dowell This improvement of addition in a better design for the Tubular Steel Dowel, it allows for many more applications of use. The ends of the tube now have at both of its ends angle cuts to form four tapered steel fingers the length of these steel fingers is deternined by the end diameter of the tube, being used to form these gang nail type fingers. Which are spread internally by adjustin of threaded steel bolts, which are located at both the tube ends.
It differs from the previous Tubular Steel Dowel, it doe's not rely upon the use of internal wood screw internal of the tube,, in which it is turned to engage with the timber member. Thus securing ths end of the Tubular Steel t0 Tube, is held to this member, its other end towards the outside tim-ber member was held by a steel bolt located into threaded nut housed with in this outer tube end.
The new drawings show in great detail how these internal bolts with a tapered bolt head to spread these gang nail type steel fingers to locate them selves into the timnber core holes into which the Tubular Steel Dowel is inserted. The tube ends when spread by the bolt adjusters embedded into the core holes of both timber members replace the need of a wood screw and external clamnping bolt. The previous method of holding timiber members together, the external clamping bolt can still be used, when a through timber core hole is in ao use. When drilled through the external timber member to clamp spread the steel tube end gang nail type fingers.
This modified design will enhance a more universal appeal towards the useage of the Tubular Steel Dowel, be cause it's mod ifS' design allows for much greater useage thus making it more comm-ercially acceptable.

Small steel support brackets supported on stinger through bolts locked into to give extra strength to treads by the slight weakening of timber treads by the drilling of core holes to house Being cold butted no checking in of treads into stringers, they give the same support to treads not check into tread stringers. Also the fujll thickness of step stringers is not I C weekend by these stringer check outs to house the tread ends into, no check ins prevents timnber rot from developing in the stringer check outs.

Figure. 21. 1ow yntte4- Manually operated adjustment of cross-timber shade members, the fixed member cross section has half of the dowel fixed permanently in it. The other end of revolves with in the main support member through bolt clamps a spring steel washer up against the splayed end of which revolves on a steel washer, abutted against main support timbefr member. This is only a method of finding, the most advantageous angles to the sun of the shading cross members for the maximum shading of windows.
Figure. 22.
Shows a different method ofjoining together two timber members by removing from the tubular steel dowel adjusting bolts This method of fastening is similar to riveting by applying of pressure on the gang nail type splined ends of the tubular steel dowels With the engagement of hand operated threaded T handle (11) threaded into internal nuts from both ends collapsing the splined ends of tubular steel dowel against both of the timber members being fastened together.
Figure. 23.
16 Its just the back view of previous figure (22).
Figure. 24.
Shows the method of clamping both splined ends of until the splined ends are filly collapsed crushed against the timber member by the pressure applied by, the hand operated T handles of (ll).
Figure. Is a method ofjoiig together panel boards, the bottom cleating board is riveted by the spreading of the end splines of The two board sections being joined together at the top are held with the pressure of tapered anti clock rotated bolt spreading of the splined ends of below the top surface of the boards being joined together band tool (11) compresses (1) splined steel fingers against under side fixing cleat.
Figure. 26.
The centre section is a composite board it acts as a clamping board, having spaced at numerous intervals tubular steel dowels with the same fixing as already explained in figure 24. There is no need for the internal adjuster bolts operated internally of The steel splined ends of are fastened by the use of T bar (11) as illustated in figure 24.
The tubular steel dowel changes its character to that of a rivet with internal threaded nuts That are engaged with counter sunk metal thread screws, to fasten such sheetings as required such as insulation sheets of plastics or sound absorption sheet miaterials etc.
Figure. 27).
The tubular steel dowel is used as a spacer between composite boards or boxing materials used in concrete fonnwork. It can also form internal division walls etc. The steel splayed ends of are slightly spread to match the counter sunk heads of metal threaded bolts to dovetail ZO these steel splines of ends against the counter sunk holes drilled in readiness for their insertion.
Figure.28.
Is a post rail fence as would be inuse around council parks seaside walks etc. Its advantage is no steel brackets no angle nailing weather protected concealed in the timber post rail members The core holes are drilled through fence post at the ground faill angle. The &connecting rail core holes are drilled to a depth to suit the protruding section of past the post on either side. The adjustment the spreading of the end steel splines of internally of the fence rails is done by alum key through the opposite end of until the steel splines of are embed into the core holes anchoring them firmnly in place a metal two pack glue over it's surflaee area- When the next rail is push into place on the section protruding past the post The alum key adjusts to spread end steel splines of the alum key is rotated through the under side of the rail being secured from with in it's core hole. Where it locates into the hexagonal bolt end of the core hole has plastic cover inserted into its core hole.
Figure. 29.
Shows wire cut clay brick with core holes for mortar to locate into as a holding medium A brick frog These type of bricks along with terna cotta bricks because of their of their internal core structure are difficult to get to hold in various masonry anchors- Because the tubular steel dowel (1) passes trough a wire cut brick to it's opposite side it has the advantage of spreading its steel splines against this brick surface of the wire cut brick. The other end the open end front of the brick, the splines of are spread with hand held T tapered tool (11) to locate them selves against the drilled core hole at the front of the wire cut brick. The splines of at the front of the wire cut brick centre resist the pressure applied by the bolt securing a timber member to a brick wall.
The opposite end of at the back of the wire cut brick firms it self against the Pull of the fastening steel bolt, as it resists with the spread of it's end steel splines of protruding either side of ft's core hole in the wire cut brick.
It's a typical brick veneer dwelling brick external wall, with the internal timber framed wall a cavity between plaster sheeting to the inside of the timber framed wall.
The timber member is shown fastened by two steel bolts that are located lock up against the brick veneer wall. As they fasten them selves into the threaded internal nut of The tubular steel dowel would have to conform to Australian standards for its adaptation as a masonry component for hollow core bricks such as. Wire cut clay bricks terra cotta bricks.
