TIE-PLATE;

Specification of Letters Patent.

Patented April 30. 1907.

To all whom it may concern:

Be it known that- I, ANDREW MORRISON, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Tie-Plate, of which the following is a full,clear, and exact description, re erence being had to the acoompanying drawings, forming part of this specification, in which I Figure l a top plan view of one form of my improved tie plate; lig. 2 is a side View of the same; and l 3 is an end view.

' My invention relates to anti-rocking tie plates of the class described and claimed in my Patent No. 622,965, dated April 11th, 1899, in which the plate is provided with thinner extensions projecting laterally from its side edges be end the rail bearing surface, and is designed to provide such a plate with a shoulder or abutment which can be readily rolled, and which requires but a minimum amount of metal in its formation.

In the drawings, the numeral 2 designates the plate which is fornicd on its under side with doWnwardly-projecting lateral flanges 3 and the intermediate flange 4.

5 indicates the reduced lateral extensions of the plate which pvovide for a maximum tie-bearing surface, these extensions being at each side of the rail-bearing portion 6.

which preferably extends entirely across the rail-bearing surface 6 .near one end of the late and terminates at the edges of such sur- Face, the outer ends of the shoulder being substantially in line with the outer sides of the flanges 3. This shoulder may, however, be

designates the rail seating .shoulder of less length, but in any case it should extend for more than half the length of the railbearing surface.

' S designatcsspilte holes, one of which intersects the shouldcr 7, and the other of which is formed through the hodyportionjof the plate.

The advantages of my invention consist in the provision of an ant i-roclcing tie-plate, having a shoulder of substantially the length of the width of the rail-bearing surface of the plate, but of less length than the idth of the tie-bearing surface, which not only facilitates the making of the plate and shoulder. but reduces to a minimum the amount of metal required.

l/Vhat I claim is 1. A tie-plate having longitudinal tie-engaging llanges,reduced extensions projecting from its side edges beyond the flanges, and a transverse shoulder of less length than the width of the plate but extending across a major portion of the. rail-bearing surface of the plate; substantially as described.

2. A tie-plate havinglongitudinal tie en gaging flanges, reduced extensions projecting from its side edges beyond its rai l-hcaring surface. and a transverse shoulder formed on the rail-bearing surfz'tce and terminating at the edges thereof; substantially as described.

In testimony whereof, I have hereunto set in y hand.
