woonmr3 PLUG ron ANCHCRING RAILS oN CONCRETE SUPPORTS.
`Application led `November 11, 1926 J Serial No. 147,769, and in Great Britain Novemherl, 1925.
Rails are most commonly anchored oncon'- `crete supports reinforced or not by means of a block of wood or other suitable material, wherein the securing means of the rail are screwed, these latter means being constituted by a suitable boltor coach screw.
None of the numerous arrangements proposed uptill now for effecting this anchoring has proven quite satisfactory in View of the requirementswhich are a suiiicient4 mechanical resistance of the recess provided inthe concrete and asuiicient resistance of the plug against unfastening, splitting and drawing out. l t
My invention has for its object a novel anchoring means of the abovementioned type answering these requirements. .v
In view of thisthe anchoring plug (preferably of hard and verydry wood) is impregnated with creosote7 or oil or any material preventing any subsequent swelling through dampness. This plug is screwed into a cylindrical recess provided in the concrete sup-v port and beyond the wall whereof projects a screw-thread bush of the Thiollier type embedded in the concrete,the recess appearing thus as a compound ironconcrete nut.
This plug has a smooth outer wall and when it is screwed into the abovedescribed compound nut, the metal bush enters into the wood of the plug by cutting or compressing and deforming the fibres of the wood. Iv prefer to chamfer the top of the bush in that projecting part` whereof which pressesr into the wood, in viewof providing an easier penetration of the metal into the fibres of the wood. 1
The plug is immersed before it is screwed down,` in a. bituminous putty or in lubricating plastic material preventing dampness f adapted to fill all the holes in the plug and to revent any oxidizing of the bush.
e securing of the plug by a spiral bush of theThiollier type allows it to resist drawing out.
It is necessary moreover in View of preventing the plug from unscrewing and splitting to bind it. The fac-t that the bush enters the wood of the plug provides a, certain binding. It may beV completed by a binding through the concrete, which is `afforded by i giving the plug a slightly frustoconical shape,
the diameter increasing from bottom to top and being larger at the top than that of the recess by an amount sulcient for the plug to remain compressed even after any shrinking of the wood.
Thev plug can be screwed into its recess by any suitable means. lt is generally neeessary to give the plug a height greater than-the depth of the. recess so as to ensure an easy screwing' down of the plug in spite of theeffortrequired therefor and due 'on Vone hand to the penetration of the bush, into the woodl and on the other to the excess diameter of the plug with reference to that of its recess. The top of the plug iscleared above the tie after it is screwed down.
I have shown by way of example two forms of my invention.
Fig. 1 is a view of a double frustoconical plug according to my invention.
Fig?, shows this plug setin its recess and provided beforehand in the tie 3 and its Walls `comprise a. spira-l bush 4 of the Thiollier type,
the spires of which projectpartly beyond the said walls, the top spire being preferably inwardly chamfered. The bituminous putty wherein the plug has been previously immersed fills all the holes including those necessarily provided at 5 at the bottom of the The libres of the wood are cut or comgreat resistanceagainst drawing out.
The rail 6 is secured to the plug 1 by means of the coach screw 7 showing a. frustoconical collar 8.
As shown on Fig. S'the lower receding part of the plug may be done away with and the said plug may appear as a simple frustocone. The rail may be secured by any other means than a coach screw for instance by a coach bolt 14 as shown on Fig. 3 with the insertion of a clip 15 and a spring washer 16 between the nut and the rail. Obviously a coach bolt may be used with the plug shown on Figs. 1 and 2 and reversely a coach screw may be used with the plug shown on Fig. 3.
j Fig. 4 is intended to show the top chamthe i `pressed and deformed and `give the plug a p fered edge of the bush, the latter being supposed seenfroin above.
What I elainiis:
l. A device for anchoring rails on concrete sleepers comprising a steel spiral bush the outer part of which is securely held throughout its length in the Wall of a cylindrical smooth-Walled recess in the concrete and the inner part of which projects inside the seid recess, u smooth Walled Wooden plug forced into the nut-shapedv recess formed by the concrete of the sleeper and the steel of the bush and a rail clamping part adapted to engage said plug. i `2.'A device or anchoring rails on concrete Asleepers comprising a steel spiral bush 'the outer part oi which is securely held throughoutits length in the wall of a cylindrical smooth-walled recess in the concrete andthe inner part of which projects inside the said recess, a slightly frustoconieal smooth Walled `Wooden plug foroedinto the nut-shaped recess formed by the concrete of the sleeper 'andthe steel of the bush, the diameter of the top of the plug being larger than that of the recess and a rail clamping part adapted to engage said plug. y
3. A device for anchoring rails on concrete sleepers comprising :1 steel spiral bush the outer part of which is Securely held throughout its length in the wall of :L cylindrical smooth-walled `recess in the concrete und the inner part of W'hichprojccts inside the said recess, :x slightly 'frustoconiczxl smooth walled Wooden plugthe lower part of which rccedes inwardly with reference to the Wall of the top part adapted to be forced into the nut-shaped recesf; formed by the concrete of the sleeper-und the steel of the bush and n rail clamping part adapted to engage said plug.
4. A device Jfor unehorinfT rails on concrete ,sleepers comprising a steel-lJ spiral bush the outer part of which is securelyT heldthronghout its length in the Wall of aVcylindrcnl smooth-walled recess in the concrete und the inner part of which projectsinsde the said recess, a smooth Walled Wooden `plug forced into the nubshnped recess formed by concrete of the sleeper and the steelof Vthe busl1,`the top-spire 'of the bush being in-` wardly chzunfered und a rail clamping part adapted to engage said plug.V
In testimony whereof I' have aflixed my signature.
