METALLIC RA|LRoADTiE. Y
SPECIFICATION forming part of'Letters Patent No. 351,499, dated October 26, 1886. Application tiled April 13, 1886. Serial No. 198,710. g (No model.)
, whichthe following is a full, clear, and exact description.
Reference is `to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of my improved railroad-tie, the ends being brokenaway and one set of spikes and keys being removed. Fig. 2 is a side elevation of a part of the same, part 'being shown in section through the broken line w w a: x, Fig. 1. Fig. 3 is a sectional end elevation of the same, taken through the line yy, Fig. 2, and showing a part of a rail in side elevation.
The object of this invention is to provide metallic' railroad-ties simple in vconstruction and strong and durable in use, and which shall be so constructedy that the rails can be readily raised above the ties and firmly secured in place in leveling a track that has been thrown out of true by the frost.
The invention consists in the construction and combination of various parts of the tie, as will be hereinafter fully described.
A represents two parallel bars placed side by side, and which may be pieces of old railroad-rails, or may be bars rolled especially for this use. In the latter case the inner sides of the heads of the bars A can be omitted, .so as to give vertical sides to the channelbetween the middle and upper parts of the said bars.
B are blocks, which are made of such a size Y and the sides and bottoms of which are made of such a shape that the said blocks will iit snugly into the channels between the bars A. I
.keys G, driven into the outer parts of the recesses E, along the outer edges of the spikes F. as shown in Figs. 1 and 2. In the outer edges ofthe upperends ofthe keys Gare formed Fo recesses H,to receive the end of a pinch-bar or other suit-able tool, so that the said keys can be readilyd rawn to release the spikes F. With this construction, when the track is thrown out of level by the frost, the keys G are with-4 65 drawn, the rails O are raised into a level position, and blocks of a proper thickness are placed between the said rails C and the blocks B, and the keys G are again driven into the recesses E, locking the spikes F and the rails 7o O securely in place. With this construction the railsCcan bereadily leveled when thrown out of level by the frost and it is impossible to relay the ties,and when leveled will be held securely in place.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patenty 1.- 'Ihe combination,'with two parallelbars, of two recessed spacing-blocks secured between 8o said bars, as specified, and spikes and wedges adapted to the recesses of the spaciugblocks, substantially as shown and described, and for the purposes set forth.
2. In a metallic railroad-tie, tne conibina- 8 5 tion, with the parallel bars A, of the blocks B, secured to and between the said bars by bolts D, and provided with pairs of recesses E, and the spikes F and keys G, driven into the said recesses,vsubstantially as herein shown and de- 9o scribed, whereby the said rails can be readily leveled when thrown out of level by the frost, and will be securely held in place, as set forth.
