INSULATED CONNECTION FOR METALLIC RAILWAY-TIES.

Specification of Letters Patent.

Patented July 18, 1911.

Application filed April 10, 1911. Serial No. 619,988.

To all whom it may concern:

Be it known that I, FRANK G. METOALE, a citizen 01' the United States, residing at Bridgeport, in the county of Fail-field and State of Connecticut, have invented a new and useful Improvement in Insulated Connections for Metallic Railway-Ties; and I do hereby declare'the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact (lG', scription of the same, and which said drawings constitute part of this specification, and represent in Figure l. a top or plan view of a section of a railway tie showing a rail secured thereto and insulated therefrom in accordance with my invention. Fig. 2 a transverse sec-' tional view of the same. Fig. 3 a side view of the clamping device, and section of the tie. Fig. 4 a side view of one form of bolt. Fig. 5 a side'view of another form of bolt which may be employed.

This invention relates to an improvement in insulated connections for metallic railway ties, the object being to provide means for securing the rails thereto and insulating the rails from the tics: and the invention consists .in the construction hereinafter de scribed and particularly rccit ed in the claim. For convenience of illustration, l have shown a tie and means for securing the rail thereto substantiz'illy like the construction shown and described in U. S. Patent No. 800,000 granted to me January 2, 1000, and which comprises a tie 2 formed from sheet metal bent to form a bottom 3, sides at, 5, l preferably extending vertically therctrom,

an end 6 turned upward trom the bottom 3 at each end and side flanges 8, 9, these flanges being inclined downward from the upper edge of the sides &, 5, all forming a trough. Preferably and as herein shown, the tie will be t'ornmd with a series of corrugationslt) tor the purpose of strengthening it. Secured to the flanges 8 and 9 are rail plates :l'ormed in two parts 11 and 12 each secured to-the flanges 8 and 9 by rivets 13. The inner edges 1- and 15 of the plates are bent downward and secured together by rivets it} and the extreme portions of the edges are turned outward and formed with notches l7 and t8. he rails 19 rest-upon these plates over the meeting edges and upon blocks 20 which insulate the ail fro the plates. The rails are held by clips 21 one on-cach side of the rail, and the sides of the clips are formed with a series of shoulders one of which bears upon the base 23 of the rails, the shoulder which bears upon the said flange depending upon the thickness of the base 23. These clips bear upon the block 20 which is sufliciently large for the purposc aml which is preferably in one piece although it is apparent that a block made up of several sections might be employed. In the said clips are holes the reception ot' insulator sockets 25 which are cup-shaped and receive insulating leeves 26 through which bolts 27 extend, the bolts being formed at their inner ends to engage with the notches 17 or 18. i I

If, as shown in Fig. 3, bolts with bar ends 28 are employed, the'bolts may enter eithernotch; but it bolts-with eyes '29 are em ployed, the eye will engage with the portion of plates between the notches. The insulating sleeves have flanges 30 attheir upper ends overlapping the upper edge of the sockets 25, and over this insulator is placed a flanged washer Ill upon which a nut. 32 bears, it being understood that the hole through the socket 2.") is larger than the diameter of the bolt 27 so that they will not come in contact with each other. The insulating block 20 insulates the clampingplates and rail from the tie-plates ll and 12, and the bolts are insulated from the clamping-{flutes by the insulated sleeves 26. Thus the rails and the means tor clamping them to the ties are insulated from the ties.

I claim The combination with a trough-shaped metal tie. plates secured thereto, rails 1'est ing on said plates but insulated therefrom said plates formed with inwardly extending notched edges, clips resting on said plates and insulated therefrom, bolts extending through said. plates into engagement. with the edges thereof, insulator SltlEVGSll'lOlllllGtl in said clips through which the said bolts extend, substantially as described;

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

FRANK G. METCALF."
