Patented A pr. 8, 1919.

Application'le. 31111622, 1918. Serial No. 241,335.

To all 'whom it may concern:

lBe it known that 1I, JAMES D. Nncus, a citizen ofthe United States, residing at Douglas, in the county of Converse and State of Wyoming, have invented certain new and useful Improvements in Railway- Track Construction, of which the following is a specification.

A The invention relates to improvements in the construction of railway tracks, the object of the invention being to prevent, what is usually termed the creeping of rails in the tracks, and which results in the tracks becoming unstable, insecure'and dangerous, and requires large expense yfor readjustment of the rails to maintainv themv in proper position and alinement so that traflic can be maintained with 'the utmost'attainable safety, atlow cost. The so called creeping lof rails in tracks, is caused mainly by the inequalities in vthe material of which the road-bedsare composed andthe somewhat unstable, loose, disconnected elements therein; especially when the road bed materials are made soft by the presence of water therein. Under such conditions, the ties supporting the rails are unstable and do not furnish as good support for the rails as should be provided. Creeping of the rails is caused by what is usually .referred to as wave action which isv almost entirely due to the causes above mentioned, and the result is to subject the rails, cross-ties, and all the elements composing the ordinary railway tracks and the supporting materials thereunder, to undue and unnecessary strains which cause breakages, disasters, wrecks and the consequent loss of human lives and destruction of property, increasing the cost of transportation onthe railways and decreasing the profits and benefits arising from the construct-ion and operation of railways under presenteXisting conditions.

The object of the invention is to provide a railway track structure which -will reduce the cost of repairs and the wear upon the metal rails, and the strain and wear upon the cross-ties, and will prevent relative lateral or longitudinal movement in any direction Vbetweenthe rails and the ties and thereby maintain the proper alinement of the rails and the proper grade'to preventl derailments and other accidents, and will stabilize and reinforce the whole track structure and the materials supporting them, so that trains can be operated thereon with safety and at reduced cost to the owners of the railways and the patrons thereof.

With these objects and other objects in view, the invention consists of the features of construction, combinationv and arrangement of parts hereinafter fully described and claimed; reference being had to the ac com paiiying drawings in which:

Figure l represents a top plan view of a section of'a track with devices embodying my invention 11i-position thereon.

Fig. 2'is a side elevation of the same.

Fig. 3 isa vertical section taken substantially on lineB- of Fig. l.

Fig. bis a vertical section taken substantially on line 4 4 of Fig. l.

Fig. is adetail section and plan taken substantially on line 5--5 of Fig. 3.

Referring nowfto the drawings, the nu- -meral l0 designates thev rail and the numeral 11 designates'the tie, and for the purpose of convenience, the numeral 11 is used to designate each of a pair of ties on each side of acentral tie`11,-`forming a group of three adjacent ties. The 'track composed of these rails and ties is preferably embedded in good dry material that is coherent, as far as possible, so asfto offer the greatest resistance to all movements of the ties in any direction out of their `proper place. Where the supporting material or ballast in which the ties arey embedded is of light unstable character, it will perhaps be advisable to specially `reinforce the ties by embedding them in hydraulic cement, so as to increase the area of their outer surface and thereby enn large the area of the material against which the ties impinge. These ties l1 and 1l are of wood, or any other suitable material.

yI form in the base of the rail 10 the opening or aperture l2 and place in this opening or aperture 12 the sleeve or washer element 13. This hole or aperturellQ in the, base of the rail is placed vinalinement or registration with the socket or opening lll which is `drilled into the tie l1 to receive the elongated pin or bolt 15 which is of the form shown, `being preferably threadless and headless, but of sufficient length to extend a suitable distance above the base of the rail, as clearly shown in the drawings. In order to properly anchor this pin or bolt 15, in the socket 1li, a small quantity of wet, mushy hydraulic cement is first poured into the hole and then the bolt or pin 15 forced therein, so that when the cement sets the bolt or pin 15 is securely held in its place, the cement 16 completely filling the hole and the pores of the Wood, and thereby preventing water or other liquid from accumulating in the hole so as to preserve the material and prevent the bolt or pin 15 from becoming loose from its anchorage in the hole. c

In the adjacent ties onk each side of the central tie 11, which have designated 11', I provide a suitable recess or bored hole 17, this being positioned in the tie so as to be beyond the edge of the base of the rail. Positioned in these sockets 17 are the elongated pins or bolts 18, which are of sufiicient length to extend slightly above the top surface of the tie and are preferably threadless and headless. Before these pins or bolts are inserted in the sockets 17, a suitable quality of wet, mushy, hydraulic cement is poured therein and when the cement sets the bolts or pins will be firmly set in the hole and the holes filled so that no water or other liquid can enter them :and .cause any loosening of the anchorage for the pins or bolts 18.

Each of the pins or bolts 18 is connected to the center or anchorage -pin or bolt 15 by means of the tie or connecting rod 19, which is looped at each end, as at 20, around the exposed end of thebolt or pin 18 and at an intermediate part, as at 21, around the exposed end of the pin or bolt 15, Whereby the pins are all securely and firmly connected together against movement, and in view of the fact that the pin 15 extends through the hole or aperture in the base of the rail, the rail itself is prevented from any movement either longitudinally or transversely, so that the track is securely held against creeping or against any movement which would tend to destroy the alinement.

Y y1t is to be understood that such an anchorage construction is utilized in connection with each rail segment or section, so that the entire track is securely held and anchored against creeping or other movement. In case the traffic is comparatively light in volume and the grades are not unusually heavy or steep, it is possible that the single pin 15 anchored, as shown, might be sufficient to prevent the rails creeping or getting out of alinement.

. It is to be noted that by inserting the pins or bolts 15and 18 in the sockets 14 and 17, after the cement or other plastic material is poured therein and driving them home,'the

plastic material is subjected to pressure which forces it into the pores of the material composing the tie and out of the top of the socket so that the bolt or rod displaces an amount of plastic material equal to its cubic contents. The sleeve 13 has a tight fit in the opening 12 and the bolt or rod 15 has a tight fit in the sleeve 13 when the same are first installed.

The invention can readily be laid as a part of a newtrack and can also be installed on any track already laid and in operation. It may be applied to a track as a Whole, or to any rail segment or section forming part thereof, as desired. The cost of the materials entering into the construction is not great, the construction is simple and may be readily and quickly installed at a minimum cost, which is amply warranted by the efficient results obtained by the use of this construction. This construction Will give efficient results With any form of road bed construction, but it is obvious that the more erture to prevent movement of the rail relative to the tie in any horizontal direction, additional elements embedded for anchorage in the adj acent ties and removable links connecting said last mentioned anchorage elements to said iirstmentioned anchorage element. h
