RAILWAY-SLEEPER.

Specification of Letters Eatent.

Patented Oct. 15,1912.

Application filed March 20, 1911. Serial No. 615,525.

To all whom may concern:

Be it known that I, JOHN McCULLocn, a British subject, residing at Lostock-Gralam, county of Chester', England, have invented certain new and useful Improvements in Railway-Sleepers, of which the following is a specification.

This invention relates to improvements in railway sleepers.

It consists of a railway sleeper composed of wood or cork saw dust or other fiber, magnesium oxid and farinaincorporated together, with a solution of chlorid of magnesium or hydrochloric acid, or lilienna as a binding material the whole being compressed under intense pressure and provided with corner pieces to prevent the sleeper from splitting, and reinforcing members embedded therein.

The invention will be described with reference to the accompanying drawings.

Figure l is a perspective View of part of the sleeperl showing the corner pieces in position. Fig. 2 is a perspective view of the corner pieces with the tie rods attached. Fig. 3 is a side view of the sleeper partly in section. Fig. l is a plan of the sleeper. Fig. 5 is a side view of a modification. Fig. 6 a detail view partly in section showing in plan the holes for receiving the dogs fitted with metal bushes. Fig. 7 is a section of same.

The sleeper A is composed of wood or cork saw dust or other fiber, magnesium oxid and farina incorporated together with a solution of chlorid of magnesium or hydrochloric acid and compressed under an intense pressure.

The following proportion of the mixture is found to give good results z-Vood saw dust 30%, magnesium oxid 25%, farina 10%, magnesium ehlorid 35%.

Metal corner pieces B of the shape shown are placed at each corner of the sleeper to prevent it splitting and to hold in position the cross or tie bars b. The metal corner pieces B and the tie rods o are placed in position before the composition forming the sleeper is compressed so that on the composition being compressed these are firmly embedded in the sleeper. The corner pieces B are provided with holes b through which the ends of the tie bars o pass and are then bent over into hook shape to hold them firmly in position.

Grooves c are formed in the top surface of the sleeper for the rails to rest in and to prevent the rails spreading out. The rails are held in position by square dogs driven into the round holes (l. Or the holes Z may be fitted with metal bushes Z as shown in Figs. G and 7 to prevent the dogs from splitting the material.

Instead of tie bars strips of wire netting b2 may be stretched across from the corner pieces as shown in Fig. 5.

Vhat I claim as my invention and desire to protect by Letters Patent is l. The combination with a composition tie, of a metal end plate, said plate being bent at right angles along a longitudinal central line, one-half of the plate engaging a surface face of the tie, and the other half of the plate over-lapping a portion of the end of the tie, said plate having inwardly extending flanges along its opposite sides, said flanges being' embedded in the tie, and being also at right angles to each other, said plate extending transversely across the tie from one side to the other.

2. The combination with a composite tie, of angled transversely extending end plates fitting respectively upper and lower edges of the tie, the said marginal portions of said plates being' bent at an angle and embedded in the tie, and metal connecting' rods eX- tending longitudinally through the tie, said rods crossing each other in the center of the tie, each of said rods being secured at one end to a plate fitted upon a lower edge of the tie, and secured at the opposite end to a plate fitted upon an upper edge of the tie.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
