Description
E. Gr. ALLE, OF BOSTON, MASSACHUSETTS.
IMPRovi-:D RAILWAY-FROG.
Speeiiication forming part of Letters Patent N0. 58,196, dated September 25, 1866.
Vin the county of Suffolk and State of Massachusetts, have invented a new Improvement in Railroad-Frogs;'and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to hea full, clear, and exact description of the same, and which said drawings constitute part of this speciiication, and represent, in-
Figure 1, a top View; Fig. 2, a side view 5 Fig. 3, a longitudinal central section 5 and Figs. 4, 5, 6, and 7 illustrate how the frog is made elastic.
My invention relates to an improvement in the construction of railroad-frogs, whereby the frog is made much lighter than heretofore, and, by the peculiar support of the point, is made much more durable; and that others may be enabled to construct my improved frog, I will proceed to describe the same as illust-rated in the accompanying drawings.
A is a metal plate the length of the frog, its eXtreme ends formed to receive the rail, and without the necessary intervention of the chair now used. B is the frog-plate, upon which is formed the heel O and the wings I) D. The plate B is placed above the plate A, resting upon transverse supports E and occasional supports F. (Denoted by broken lines, Fig. l.)
The main rail T is placed upon the lower plate, A, and by means of spikes through the plateA is secured to the tie in the usual inanner, thus avoiding the necessary use of a chair.
The point P is of the usual form, and in addition to the usual security I form at its extreme point and upon its under side a plate, f, which iits int-c acorresponding recess in the plate B, as seen in Figs. l and 3, and bolted therein, or otherwise secured, this forms a security to the point by the broad surface of the plate j not heretofore attained.
To make this frog elastic, which it is desirable in many cases to do, I form a recess in the upper surface of the transverse and occasional supports, as seen in Figs. 4 and 6, into which I place a sheet of india-rubber or other equivalent material, h, and placethe upper plate upon this elastic substance, and bolt the parts together, as before. The elastic substance `should project a little above the supports.
This elastic substance may, with the same result, be placed upon the under surface instead of the upper, or upon both upper and lower,
E. Gr. ALLEN.
