RAL ANCHOR,

MPLFLQATION FILED 1130.29.1906.

ITO/@VE V5 To AaZLwh/omv it may concern.; l. Be it known that I, JOHNA. MURPHY, -a citizen of` the ,Unitedv States,- .residing at.` White Haven, in the/countyoffLuzerne and State of Penns lvania, have invented ya new and useful Ra' -Anchor, of which the following is a specification.

Considerable diiculty is experienced in railroad-track construction, especially on heavy or steep grades and at curvesby the 4rails running or creeping. This is due in a measure to the expansion and contraction of the steelrails under temperature changes.A Also the rails will run. or creep with the trains passing over them and cause the track to kick or buckle out of line in hot weather. Consequently the track has to be fre uently restored by a laborious operation. o pre- .vent thejrunning or creeping of the rails, de-

constructions, the anchor being made in two arts and rovided with means for iirmly ocking sai arts in position on the rails, so` that the anclior or anchors will engage the cross-ties and prevent the rails from creeping with respect to the latter. L

With these ob`ects in view and others, as will appear as t e nature of the invention is better understood, the invention comprises the various' novel features of construction and arrangement of parts which will be more fully described hereinafter, and set forth with particularity in the claims appended hereto.

Inthe accompanying drawing, which illus` trates one of the embodiments of the inven-` tion, Figure 1 is a transverse section of the rail-anchor, showing the end of 011e of the rails. and the shank of the fastening-bolt PATENT A l viii i" y speeicaiii'onlof Letters Patent.

be of any ap roved construction and comprising a headp1, a web 2, and a base 3.

The anchor or support vB is composed of two longitudinally-divisible sections 4, which meet in a plane passing centrally through the web 2, and these sections are secured to-1 gether under the base of the rail by the trans'- versely-extending bolt 5: The sections 4 are metal castings each comprising a body composed oftwo vertically-dlsposed side Walls .or webs 6, connected together by flat vertical gle or square. The webs at the inner portions of the sections are somewhat larger than the outside vertical webs. The two vertical outside webs of the sections are provided with inwardly-extending flanges 7, that engage over the outer edges and top of the base 3 ofthe rail, so as to support the anchor on the latter. lThe four walls of the sections extending parallel with the length of the rail are provided with alining openings 8,through which the bolt 5 extends. By means' of this bolt the two sections are drawn together inwardly'with res ect to the base 3 of the rails, 'and the bolt is ocated approximately under the point where the rails meet.

In order to increase the grip on the rail, the inner walls of the sections are provided with serrations 9 and the end vwalls with serrations 10, which serrations bite into the under side of the base 3. The outer walls have on their inner surfaces the serrations 11, which engage with the edges 12 of the base 3, and on the under surface of the inclined overten ing serrations1 13,`which engage the top surface of the base 3. By means of these anchor is positively prevented.

In practice the anchors are placed on the rails with their flat Webs 6 bearing against the cross-ties, so that the rails cannot run or move without carrying the ties with them. Insome cases, as on very heavy grades, five or sixl anchors are applied to each rail-section of the track. When the parts of the anchor partly broken away. Fig. 2 is a perspective view oi one section of the rail-supporter with a portion broken away. Fig. 3 is a side view of one section of the rail-support.

lGorraspending parts in the several figures not abut, and when the bolt Sis drawn up tight' the Darts will be forced into contact at the lower edges of the inner webs, as shown in Eig.' 1.
