RAE AY F R@ G SPECIFICATION forming part of Letters Patent No. 319,362, dated June 21, i895.

Application led August 14, 1884. (No model.)

To a/ZZ whom t may concern,.-

Be it known that I, FREDERIC C. WEIR, a

`resident of Cincinnati, in the county of Hamilton and State of Chio, have invented certain newT and useful Improvements in Railway- Frogs, of which the following is a specification.

My invention relates to an improvement in railway-frogs, and particularly to that class known as channel-iron frogs.77

One of the objects of my invention is te provide iilling-blocks which will furnish vertical support to the rails as well as lateral support to the channel-irons.

Another object of my invention is the employment of a through-bolt for binding the parts of the frog together. Through-bolts have not been hitherto employed in channeliron frogs; but three series of bolts are used, binding each wingof the channel to its abutting rail separately. y

My method of strengthening and uniting the parts is at once cheaper and more durable than three series of bolts hitherto employed, all of which will be fully explained in the description of the accompanying drawings, in whiehy Figure l is a top plan View of my invention; Fig. 2, a cross-section on line x as, Fig. 1; Fig. 3, a side elevation of one rail, showing the block and channel-plates in section. Fig. 4 is a perspective View of one oi my improved filling-blocks.

A A represent the ordinary wing-rails of a railway-frog; BB', the point-rails, which may be united or tted together by swaging or grooving, as desired.

D D represent the ordinary channel-irons, the wings of which iit the webs of the rails forming the frog.

C C represent filling-blocks, the contour of which fits the channels D. c represents a hole or recess pierced in the block C, for the admission of the through-bolt E. I have shown two forms of this illing-block-one in Fig. 2, in which the block is pierced with a hole larger than the bolt itself, and one in Fig. 4, which shows a recess or opening adapted to receive the bolt. The base of block C rests upon the channels D, and the ledges a project upward and abut against the under side ofthe rails, thereby furnishing also a ver Vnel upon each side of the web of the pointrail,so as to hold the channel up to the point.

The bolt draws these parts together and holds them in a substantial position.

Instead of a continuous channel-iron, two or more Ushaped irons, one placed in front of the other,might be employed with good results.

Vhen the lling-blocks and through-bolts are used in connection with the` channel-irons D,the latter may be shortened,instead of having them extend as far to the rear as I have here shown, and the filling-blocks employed in rear as well as in front of the channel-irons.

, Another modification would be to have my llingpieces rest upon and be held in position byv a through-bolt,which would clamp the end of the filling-pieces against the wings of the channel and preserve the space between the rails, and yet unite the parts together to form a substantial structure.

1. A railway-frog composed, substantially, of wing and point rails, channel-irons D and filling-pieces, and through-bolt E, adapted to clamp the structure and preserve the space be tween the rails, substantially as described.

2. In combination with a channel-iron railway-frog, a filling-block, C, iitted to the channels D, substantially as specified.

. 3. A iilling-block, C, provided with lugs t', in combination with the channel-irons for supporting the main point-rail, substantially as specified.

In testimony whereof I have hereunto set my hand.

FRED. C. VEIR.
