' INSULATED SWITCH-BAR FOR RAILROADS.
Specification of Letters Patent.
Patented Aug. 24., 1909.
Application filed February 29, 1908.' Serial No. 418,585.
Be it known that we, GEORGE .W. WHITE-- MAN and. CHARLES WMREI'NO'EHL, citizens of the United States, said WHITEMAN residing in the city and county of Philadelphia, State of Pennsylvania, and'sa'id R INOEHL residing at Steelton, Dauphin county, State of I Pennsylvania, have nvented certain new and useful Im rovements in Insulated Switch-Bars for l ailroads, of which the following is a full, clear, and exactdescription,
' portions of'the two sections into alinement.
reference being had to drawings, of which- Figure 1 is a section across a railroad track, showing a switch barembodying our invention and connected to the point-rails "of a switch. Fig. 2 is a plan view of the portion of the switch bar in which'our invention is embodied. Fig. 3 is a vertical medial section through the same.
The object of our'inventio'n is to provide a strong and efficient switch bar or connecting bar, one portion of the same being electrically insulated from the other portion.
To this end the invention consists in dividing the usual connectingbarorswitch barinto two portions, overlapping each other in the na ture of a splice, and whose opposed surfaces are separated by an intervening strip or plate of insulating material, the said overlapping ends being secured together by means insulated from one or both of the bars.
The precise nature of the invention will be hereinafter particularly iointed out.
1, 1, are the usual stoc rails, and 2, 2, the point rails ofa railroad switch; 3, the lugs sethe accompanying ivot'ally connected to said lugsjin the well mown manner.-
The bar, 4,. is divided into two sections,
faces consist of complementary undulations, said surfaces being separated from each other by an intervening strip or plate, 5, of insulatin material. Each section 4? and 4 of the bar 4 is bent nearthe meeting ends of the sections, as shown, to ofiset the overla ping ends from the longitudinal centers- 0 the sections, thus bringingthe main body with each other. The overla ping ends are secured together by means of olts, 6,'which, Y with their nuts, 7, are eachinsulated from .of saidparts, substantially as set forth. cured to the point-rails, and 4, the switch bar one portion of the*ba'r, 4, by an insulating .washer, 8.
We remark that, by the construction shown and described, not only is the thickness of the switch bar rod at the joint between its parts reduced to a minimum; but, by reason of the undulating or curved surfaces of the connected parts, much greater longitudinal strength is attained than would be the case were the overlapping ends of the bars a plane surface.
Having thus described our invention, we claim as new and desire to secure by-Letters Patent 1. A connecting barvor rod for railroad switches and the like, comprising two sec. tions whose adjacent ends are provided with overlapping undulating o posite surfaces, one of said sections being ent to offset the overla ping portion thereof from the longitudina center of the section, the insulating material between said surfaces, togetherwith means insulated from one ofsaid parts secur ing said overlapping ends together, substantially as set forth. a
2. A connecting bar or rod for railroad switches and the like, comprising two sec- ;the bolts securing said parts'together, said bolts being respectively insulated from one 3. A connecting bar or rod for railroad switches and the like, comprising two sections' whose adjacent ends overlap each other, one of said sections being bent to orf:,
set the overlapping. portion thereof from the longitudinal center of the section insulating material between said ove'rla ping ends, 'to gether with means insulated fi om one of said parts securing said overla ping ends together, substantially as set orth.
In testimony whereof, we have hereiinto I aflixed our signatures.
