RAIL-STRINGER.

SPECIFICATION forming part of Letters Patent No. 295,567, dated April 8, 1884.

Application filed December 15, 1883.

To alii whom, t mrtg; concern:

Be it known that we, HENRY HOLGATE, of the cit-y of Toronto, in the'county of York, in the Province of Ontaria, Canada, civil engineer, and ROBERT Beernem., of the city of Hamilton, in the count-yet' ientworth, in the Province of Ontario, Canada, road-master, have jointly invented a new and useful Rail- Stringer; and we do hereby declare that the following is a full, clear, and exact description of the saine.

The object of the invention is to utilize oldv rails in the construction of rai1stringers for cattle-guards and open culverts; and it consists, essentially, of a rail-Stringer formed of two Trails laid on their bases side by side, the inner edges of their bases touching or nearly touching each other,a similarly-shaped center rail inverted and slipped between the two side'rails, the anges vor' the center rail resting on the heads of the side rails, and the bottom of its base presenting a level support for the running rails, the Asaid rails so arranged being held together by clips, substantially as hereinafter explained.

Figure l is a perspective view of a cattleguard, showing the running rails crossing it supported by our improved rail-stringer Fig. 2 is an enlarged perspective detail of our improved rail-Stringer. Fig. 3 is a cross-section of the same.

In the drawings lihe letters of reference indicate corresponding parts in each gure.

A are two ordinary T-rails laid on their bases side by side, so that the inner edges of their bases shall touch each other, or nearly so.

B is also a T-rail, inverted and slipped between the rails A, the flanges of the base on the rail B resting, as indicated, on the heads of the rails A, and as the rails A and B are the same pattern, the head of the rail B will of course be in contact with the top side of the flanged bases of the rails A. As the space between the bodies and heads ofthe rails A and B, if not tllled'up, would prevent them being clamped together, we insert, atsuitable distances apart, short iron blocks or packingpieces F, the most suitable material ont of which to make these blocks being pieces of old fish-plate, although, of course, we do not confine ourselves. We may also say that, While (No model.) Patented in Canada December 19, 1883. No. 18,332.

for an ordinary culvert or cattle-guard it will be found sufficient to insert the packing-pieces F at either end ofthe rail, more pieces may be put in, if desired. The running rail C rests upon the base of the rail B.

D are clip-plates bent in pairs opposite to each ot-h er on the combined rails, as indicated, fitting close into the body of the running rail C, and thence, descending ,from its head, follow the outline of the top rail downpast its anges, and thence around the outline of the head of the rails A, extending straight down from that point to the base of the rail A. The space between each clip-plate D andthe body ofthe rail A is lled up by a block or paolo.

ing-piece, F, similar to the packing-pieces on the other side of the rail. The clip-plates D are preferably placed about two feet apart, and are bolted together by the bolts E, as indicated.

y In order to form asolid and substantial support for the railstringer constructed as described, We place on the top timber, G, of the cattle-guard or culvert an iron plate, H, having spike-holes bored' in each plate at a distance apart representing about the width of flanges of these rails are notched opposite to where the holes in the plate H come, so that the spikes which are driven through the holes in the plate H to secure it to the timber G shall iit into the notches cut in the outer edges ofthe -flanges of the rails A, and thus bind them together.

As short rails and old pieces of sh-plate may be used in the construction of our railstringer,rail-stringers constructed in accordance with our invention will be exceedingly cheap. Moreover, by resting the stringers thus made on the plates H, the shimniing necessary in the Winter maybe effected under the plates, thus insuring a more secure track than Were the stringere to rest immediately upon the top timbers, G, of the cattle-guard or culvert.

What We claim as our invention isl. As an improved rail-Stringer, two T-rails, A, laid on 'their bases side by side, the inner edges of their bases touching each otheigor nearly so, a similarlyshaped center rail, B, inverted and slipped between the two rails A,

the combined bases of the rails A. The outer` IOO the langes of its base resting on the heads of the side `rails, and the bottom of its base pre senting a level support for the running rail C, in combination with clips arranged to combine the rails together, substantially as and for the purpose specified.

2. The rails A'and B, arranged as described, so as to form a support for the running rail C, the clipplatesD, and bolts E, arranged to oombine the rails together, in combination with packing-pieces F, inserted between the rails A and B, and between the rails A and clipplates D, substantially as and for the purpose specied. o

3. In combination With a rail-stringer com- 15 posed of the rails A and B, arranged and cornbined together as described, a plate, H,4 placed on the timber G, and held there by spikes driven into the timbers through holes in the plate, and notches cut in the outer edges of 2o the flanges of the rails A, substantially as and for the purpose specified.
