Specification of Letters Patent. Patented June 24, 1919- Application filed September 13, 1918. Serial No. 253,903.
To all "whom it may concern Be it known that 1, JOHN ARTHUR Ronnms, a subject of the Klng of Great Britain, residing at CunardBuilding, Liver-- fastenings cast in the concrete sleeper work loose in use and do not permit adjustment of the chairs to the rail gage.
This invention has for its object to provide sleepers and chairs which are free from such difliculties and objections. the sleepers and chairs [being connected together without the use of spikes, bolts, screws, trenails, or other usual f-astenings, and without weakening of the sleepers by their being pierced, or out, after formation, while firmand secure connection of the chairs, or the main part of the chairs, to the sleepers is secured; the chairs, or main part of the chairs, being practically integral with the sleepers. The
invention also provides the chairs with easrly renewable means acting as resilient rail supports, and means forready adjustm-ent of the chairs and rails to suit the gage of the track. l
According to this invention, each chair, or a. portion, or portions, thereof,is,or are made practically integral with a sleeper of concrete, reinforced concrete, or the like, (which I will refer to as concrete hereinafter and in the claims) preferably: in such manner that the chair is composed of at least two portions of which one portion is fixed in, or is practically integral with, the sleeper, while the other portion is movable. The fixed portion of the chair is internally large enough to allow the rail to be dropped in and removed readily, while the rail is anchored in position by the other portion of the chair, rigid attachment beingisecured by a wooden, or other suitable member, or wedge.
The fixed portion of the chair is provided, with one, or more than one, projection to give satisfactory hold in, or adhesion to, the
sleeper, and these may engage reiniiorcing material in the concrete.
The movable portion of the chair is of l10l -like form and is placed within the trough formed by, the fixed PO'l'blOllOf the chair, one part being opposed to one side of, the rail, and. a horizontal part extending under the rail.
Cushioning devices are provided to cushion the hammer shocks from traffic pass ing over therails and packing pieces are i11- sorted in the plane of contact between the portions of the chair to render the chairs easily adjustable to the gage between the rails.
Thefollowing is a construction in accordance with this invention which will explain how the invention can be performed. We will describe it wlth reference to theaccom panying drawing. Figure 1 is an elevation ofa sleeper with its two chairs. Fig. 2 shows a part of the sleeper and one chair and isdrawn to a larger scale than that to which Fig. 1 is drawn. Fig, 3 shows part of chair separately and Fig. 4: shows, separately, a resilient pad for the rail. The sleeper A, is presumed to be of reinforced concrete, and the metal, chairs, are made in two portions, one portion B being formed. with the jaw b .(betweenwhich and one side of the rail C a. wedge D is passed) and with anexternalweb b (or external webs) projectingfromfthc said portion B and perforatedfif desired, as shown for instance at 6 This web, or these webs, is or are, embedded in the material of the sleeper A so that the said portionB of the ehairis fixed to, and held firmly in, the sleeper. The second p-ortion 13 of the chair is movable and consists of a metal piece comprising a lower horizontal part b to receive the lower flange, or foot, of therail C and a jaw 12 to bear against one side of the rail when the wedge D is driven home.
i To give resilient support to the rail a pad E (or pads, or strip, or strips) of wood, or other suitable material, is placed between the inside of the fixedportion B of the chair and the lowerside of the horizontal part 1 of the movable portion B of the chair, on the upper side of which horizontal part the lower flange, or foot, of the rail rests. The thickness, of such pad E, or strip, or the like, or the number of pads, or strips, or the like, can be varied to adjust the position of the rail in the chair, the two portions of the chair being preferably made to allow of some vertical movement between them to permit of such adjustment.
If desired the two portions of the chair, instead of bearing directly against each other at the side 00 where the jaw of the movable portion B is situated, may have packing, or shipping-strips introduced to insure an even surface between them, or liners of wood, or other suitable material, can be inserted between them for adjustment and to give any required resiliency, or cushioning, at these parts.
If desired, reinforcing metal of the sleeper may be made to engage the web, or webs, or equivalent projections, from the chair, or fixed portions of the chair, for example as shown at f, Fig. 2.
The parts in connection with the chair, (or portion of the chair) which are embedded in the concrete can be made in one with the fixed portion of the chair, or be made separately therefrom and be attached thereto.
What I claim is 1. The combination with a concrete railway sleeper, of a rail chair comprising a fixed part permanently secured to the sleeper and channeled to receive the rail carrier, and an independent part fitting freely within the channel of the fixed part and constituting the rail carrier, said carrier having a foot piece adapted to underlie and support the railand an integral side piece adapted to engage one side of the rail and to bear against one side of the channel in the fixed part, together with an independent cushioning member interposed between the foot piece of the rail carrier and the bottom of'the channel in the fixed part.
2. The combination with a concrete railway sleeper, of a rail chair comprising a fixed part permanently secured to the sleeper and channeled to receive the rail carrier, and an independent part fitting freely within the channel of the fixed part and constituting the rail carrier, said carrier having a foot piece adapted to underlie and support the rail and an integral side piece adapted to Copies of this patent may be obtained for engage one side of the rail and to bear against one side of the channel in the fixed part, together with an independent wedging member interposed between the opposite side of the channel in the fixed part and the rail.
3. The combination with a concrete rail.- way sleeper, of a rail chair comprising a fixed part permanently secured to the sleeper and channeled to receive the rail carrier, and an independent part fitting freely within the channel of the fixed part and constituting the rail carrier, said carrier having a foot piece adapted to underlie and support the rail and an integral side piece adapted to engage one side of the rail and to bear against one side of the channel in the fixed part, together with an independent cushioning member interposed between the foot piece of the rail carrier and the bottom of the channel in the fixed part, and an independent wedging member interposed between the rail and channel on the opposite side of the latter from that against which the rail carrier ears.
4. In a concrete railway sleeper, a metallic reinforcing element extending lengthwise of the sleeper transversely to the trackway, a rail chair having a fixed part embedded in the concrete of the sleeper and anchored to said transverse reinforcing element, said fixed part being channeled to receive the rail carrier, in combination with an independent part fitting freely within the channel of the fixed part and constituting said rail carrier, said carrier having a foot piece upon which the rail rests, and a side piece to engage one side of the rail, together with a cushioning element between the foot piece of the rail carrier and the bottom of the channel, and a wedge block interposed between the opposite side of the rail and the adjacent side of the channel.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN ARTHUR ROBERTS.
