- RAILROAD-CROSSTIE.

Application filed November 8, 1919.

T 0 all whom it may concern.

Be it known that I, JUDD IV. HULBERT, a citizen of the United States, residing at Aberdeen, in the county of Harford and State of Maryland, have invented certain new and useful Improvements in Railroad- Crossties, of which the following is a specification. V

My invention relates to an improvement in railroad cross-ties, and the object is to provide a secure fastening, and at the same time cushion the rail, provision being made for fastening it without the use of spikes or bolts.

My invention consists in a railway crosstie of I-beam form chambered out to receive the rails, and having a depression in the chambered out portion to receive a block of wood, which acts as a cushion to the rail, in connection with securing blocks and a pin for holding the latter in place.

In the accompanying drawings Figure l is a view in side elevation with a part broken away;

Fig. 2 is a top plan view partly broken away;

Fig. 3 is a section on line 33 of Fig. l.

A, represents the railway cross-tie made of metal rolled in I-beam form. This is chambered out as at l to receive the rails which are lowered through the opening at the top.

In the bottom of each chambered-out portion, a recess 2 is made, and in this a block 3 preferably of wood is placed, and upon these blocks the rails a rest, whereby a cushion is formed which relieves the rigidity that would result from the rail otherwise resting on a metal part. A rounded recess 5 is formed in one end of each chambered out portion 1 to receive the securing-blocks 6 which have a rounded portion and are adapted to be inserted endwise therein and rest at their upper edges against the webs of the rails just above the base, thereby holding the rails securely in place against the opposite edge 7 of the chambered out portion.

The top of the securing block is engaged on the upper side and at the base thereof by the inclined wall adjacent the rounded recess, the lower side of the securing-block fitting and adapted to engage the upper surface only of the adjacent side of the rail base and the rail web, and bridging the open space interposed between the adjacent edge of the rail base, the upper surface of the Specification of Letters Patent.

Serial No. 336,655.

rail base and the interior wall of the recess in the tie being approximately parallel.

A pin 8 extends through a hole 9 in the cross-tie, and a hole 10 in the securing block for holding the latter in the recess against movement transversely of the tie. This cooperating rounded recess and the rounded end of the securing-block lessen the possible strain on the fastening-pin 9 by preventing longitudinal movement of the securing-block relative to the tie, yet permitting of a very slight vertical movement due to the slight vibration and by the rail resting on the wooden cushion block 3.

In this way, a simple means is provided for rigidly securing the rails in place at a uniform gage, and without the necessity of using the usual spikes.

The railroad cross-tie is inserted at inter- 'als between ordinary ties.

I claim:

In a metallic tie and rail fastener comprising a crosstie with its upper edge chambered out a sufficient width relative to the width of the rail base to receive said rail laterally, and one side of the chambered portion fashioned to snugly fit one side of the rail web and base, and having a rounded recess formed in the opposite end of the chambered-out portion with the interior wall inclined adjacent thereto and therefrom approximately parallel to the inclined upper surface of the rail base but spaced therefrom, the chambered-out portion being recessed and a cushion-block inserted in said recess, upon which the rail rests, a securing block having a rounded portion constructed and adapted to lit in the rounded recess, whereby the securing-block is held against longitudinal movement of the tie, and the top of the securing block being engaged on the upper side and at the base thereof by the inclined wall of the tie adjacent to the rounded recess, the lower side of the securing block fitted and adapted to engage the upper surface only of the adjacent side of the rail base and the rail web, and bridging the open space interposed between the edge of the chambered out portion of the adjacent edge of the rail base, and a pin adapted to register with openings in the cross-tie and the securing block centrally thereof, Whereby the block is held against movement transversely of the tie.

In testimony whereof I affix my signature.

J UDD W. HULBERT.
