ing means for effectively insulating the rail base of any type of insulated rail joint, while at the same time baseinsulation.
In those types of insulated rail joints wherein-base insulation is interposed between the rail .base and the joint sup ort or bridge, and no provision is made for re ieving such insulation from the 'load, the lifetime thereof is greatly impaired through the combined influences of the traffic and weather conditions. It is exceedingly diiiicult to secure an insulating material or composition that will withstand those conditions when em loyed as a base insulation between the rai base and the joint support or bridge, inasmuch as it iswell known' to railway engineers that the vertical movement of the rail ends of any railjoint, and particularly of the joint, will have a tendency to shear or cut out the insulating base piece of the said joint, and will also have a entirely dispensing with the tendency, under the pressure of the load, to
\ cause the said insulation to flow and disintegrate especially where the insulation has become wet or damp. It is, therefore, the
purpose of the present invention to obviate these objectionable results in insulated rail joints, by entirely dispensing with base insulation, while at the same time maintaining a thorough and effective insulation of the base portlon of the joint.
With these and many other objects in view which will be familiar to those skilled in the art, the invention consists in the novel concomblnatlon, and arrangement of struction, parts hereinafter more fully described, illus- 'trated,'and claimed.
. The essential feature of the invention involved in maintaining a normal seplaration of the and joint proper from t e jointv support or base, embodiment in a multiplicity of structures 5 on account of the great variety of joints with l which he invention may be associated also, i on account of the variety of expedients that may be resorted to for the purpose of. maintaining the separation referred to and atthe vsame time ermitting the rails and joint roper to see and rest upon a rigid supportmg base when the load is passing thereover. However, for purposes of illustration, there is shown in the drawings an embodiment for carrying the invention into effect, and in these drawings, 7
Figure 1 is a sectional perspective view of an insulated rail joint equipped with an improved pase construction in accordance with this invention. Fig. '2 is a side elevation thereof;
Like references designate corresponding parts in the several figures of the drawings.
In carrying the invention into effect, any
is necessarily susceptible to;
type of splice or joint may be utilized to connect the rail ends, as the distinctive feature sought to be covered herein resides in that of normally and yieldingly maintaining a rail joint'proper and the rail ends held therein,
elevated above or separated from the base joint support or bridge and at the same time msulating the rail ends from said support or bridge and ermitting the rails to seek andfind a rigid earin on said joint support, or bridge when the oad is imposed t ereon. For the urpose of exemplifying this novel form of g 'oint's,

The feature of providing suitable base insulation for-the rail ends is provided for by the present invention, and in connectionwith the form of construction being described, it
will be observed that thereis associated with the rail joint proper '(above described a joint supporting base 6. This my be in the plate of the reinforced It is iiitended that there supporting base 6 and the rails while at the same time a separation is maintained be tween these elements. To eflect this, various forms of construction may be resorted to, but in the one now referred to, a plurality of insulating springs 7 may be interposed be- 7 tween the metal supporting base 6 and the base "of the rails A A, said springs being of sl'ifiicientnormal projection and strength to provide for maintaining the rail ends inan elevated position with the said metal supporting base. The
said' insulating springs 7 may. be of rubber,
composition, or of equivalent material pos-. sessing the necessary elastic and insulating qualities, or said springs may be of metal with a sheet oflinsulating material between the springs and the rail, or between the springs and their supporting base.
