LUGIEN HENRI DELLOYE, OF PARIS, FRANCE, ASSIGN OR TO SOCIETE ANONYME DES MANU- FAGTURES DES GLAGES ET PRODUITS OHIMIQUES DE SAINT-GOBAIN, OHAUNY ET CIREY,
OF PARIS, FRANCE.
THIRD-RAIL INSULA'IOR.
T 0 all whom it may concern:
Be it known that I, LUCIEN HENRI DELLOYE, a resident of Paris, France, have invented the Improvements in or Relating to Improved Third-Rail Insulators, of which the following is a specification.
This invention has for its object an im roved method of mounting insulating blocks, formed of molded glass, stoneware or other insulating material, whereby the insulating blocks are rendered one with the conductor rail while yet being capable of movement relatively to their supports.
The invention consists in the novel combinations or arrangements of parts as will be hereinafter particularly pointed out in the claiming clauses.
One way of carrying out this invention is illustrated by way of example, in the accompanying drawing.
Figure 1 showing in sectional plan a portion of a conductor rail provided with an insulator, and Fig. 2 being a part vertical section corresponding to the line 23 of Fig. 1.
The conductor rail A which may be of any form, but is generally of I shape, rests upon the upper part of the insulator B which may be molded to fit the shape of the rail.
The rail and the insulator are held assembled in a rigid manner by means .of two pieces of angle iron 0, or special laminated, forged or stamped pieces, secured in position by bolts D that do not traverse the mass of the insulator B and which pass beneath the conductor rail A. By tightening the bolts the lower wings of the angle irons C will bear against the slo ing lateral walls of the insulator B and ho d it in place below the rail by simple grip ing contact.
The insu ator has a drip groove E that assures the fall of rain water and gives entire .security from an electric insulation point of view. The insulator rests on its depending base which may be round, square or of any form, with or without the interposition of an elastic cushion, in a recess formed in a piece of wood or any other material F that is generally fixed to a cross bar or sleeper of the road. The bending of this cross bar or sleeper can thus freely take place without carrying with it the insulator and the conductor rail to which it is connected.
Specification of Letters Patent.
Application filed October 5, 1905.
Patented May 19, 1908.
Serial No. 281,519.
What I claim is 1. The combination with an electricity conducting rail of an insulating block, having a depending base and slopling lateral walls at its upper part, gripping p ates adapted to bear against the rail and the sloping walls of the block, means for drawing said plates towards one another and a support on which said block simply rests, substantially as set forth.
2. The combination with an electricity conducting rail of an insulating block formed with sloping lateral walls, oppositely arranged angle shaped gripping plates one arm of each of which bears against the lower flange of the rail and the other arm of each of which bears against a sloping lateral wall of the block, each gripping plate extending at each end beyond the said insulating blocks, and tightening bolts connecting said gripping plates at portions thereof beyond the insulating block, substantially as set forth.
3. The combination with an electricity conducting rail of an insulating block formed with sloping lateral walls, oppositely arranged angle shaped gripping plates one arm of each of which bears against the lower flange of the rail and the other arm of each of which bears against a sloping lateral wall of the block each gripping late extending at each end beyond the saic f insulating blocks, and tightening bolts that are located below said rail and that connect those portions of said plates projecting beyond said block, substantially as set forth.
4. The combination with an electricity conducting rail of an insulating block, gripping devices adapted to bear against the rail and the block, means for drawing said devices towards one another and a recessed support in the recess of which said block simply rests with freedom of lateral movement.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
LUCIEN HENRI DELLOYE.
