SPLICE F015l BAR-RAILS.

Specification of Letters Patent No. 22,785, dated February l, 1859.

Toall whom it may concern.'

Be it known that I, VVILLMM M. C. CUSH- MAN, of the city and county of Albany and State of New York, have invented a new and Improved Splice of BarRails; and I do hereby declare thatI the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention consists in making a splice of bar rails with an upper and lower fianch or rib hereinafter described, so that the lower one sha-ll be directly under the rail and thereby give greater strength to the base plate of the splice, and better support the immediate ends of the rails while the upper one extends upward outside of the rail and close thereto until it reaches the t-op thereof so as to prevent the lat-eral displacement of the rails as well as sucker heads, and thereby relieve the lateral thrusts against the immediate ends of the rails.

I construct my splice plate or piece of wrought or cast iron, or of any other material thought best to be used. Vhen made of cast iron, the upper and lower flanch or rib must be cast of suiicient thickness to answer the purpose required. The lower one may be extended downward as far as required to give strength and support to the ends of the bar rails, and to hold the splice in its proper place. When made of wrought iron, it may usually be made of a flat bar from one fourth to one half of an inch in thickness, and from six to ten inches in length, and bent as shown in the drawings at Fig. 6 of the` drawings attached to my patent of Jan. 16th 1845 for improvements in rails for rail roads, and which was one figure upon which I made an application for a patent for splice of bar rails July 19th 1844. This splice plate or piece may, also, be rolled from iron by means of machinery properly constructed, which when done the upper flanch or rib will be solid of any thickness required. The bed piece upon which these flanches or ribs are constructed if made of cast iron would require greater thickness, but dimensions may be named by the engineer. vWhen this splice plate or piece is bent from iron as hereinbefore described the flanches or ribs are formed by heating plate iron and bending, and forging the ribs into solid connection therewith, whereby good splicing bars may be constructed at any common forge, which mode was suggested to :adapt their production to the state of this count-ry, ygenerally. If made either way as 'herenhefore described a very cheap, strong and durable splice plate or piece for flat bar rails for rail roads is made.

Fig. 6, of the drawings aforesaid, shows a splice plate or piece ready for use. c) is the flat bar rail; (s) is the spike, which passes through this rail (c), through the bed of the aforesaidY splice plate or piece, and into the string piece upon which rests the said splice and the said rail, (a) is the lower flanch or rib, is the upper and outside flanch or rib, both of which I have hereinbefore described by denominating them the upper and lower flanch or rib. This entire splice plate or piece is let into the top of the string piece its whole thickness, so as to form a continued bearing surface for the flat bar rail, and it may extend from the joint where the said rails meet to any distance each way therefrom, .and when used with said rails where cross ties are used, it may extend from any tie over which the rails join to the next cross-tie each side therefrom adopting the base plate and side flanch thereto in point of strength. This figure s a vertical view at right angles with the track rail (c).

At Fig. 7, will be seen two flat bar rails (c, c) forming a joint in the track, which joining together is made strong and durable by means of the splice plate or piece herein described, so that, when the cars pass upon this part of the track or rail it will be as strong, if not stronger, than any other part thereof. This modified figure (7) of the drawings attached `to my patent of J an. 16th 1845, together with the aforesaid Fig. 6 thereof, completes the full drawings upon which I made my aforesaid application for a patent, July 19, 1844. This ligure is a modification of Fig. 6, aforesaid, and may or may not be used. Like figures, however, refer to like parts. It is upon these same ligures herein described, that I make this ap plication, which is a renewal of my application for a patent for Splice of bar rails, on the 19th day of July 1844, using the drawings of my patent aforesaid now upon file at the U. S. Patent Ofice.

The spikes may have a key or screw, and

nut upon the under side of the splice plate or piece hereinbeiore described. Having thus described my invention and having also described the flanch, llet or rib (b) outside of the fiat bar rails, and up to and even with the top or bearing surface thereof, it is hereby expressly understood, that I do not claim it even therewith for the purposes of receivingthe tread of car Wheels or any part thereof, of any train of cars passing over the rails of any railroad, or for any other purpose than specially to add strength to the splice plate, and to prevent lateral displacement of the flat bar rails tgforcsaid, by means of the said splice plate; 15

Ihat I do claim and desire to secure by Letters Patent, is:

In combination With the flat bar rail, the splice plate or piece-Fig 6-constructed 20 in the manner and for the purposes herein described.

In witness whereof, I have hereunto set my hand on this 10th day of J an. 1859.

WVM. M. C. CUSHMAN.
