BANOROFT G. BRAINE, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE RAIL JOINT COMPANY,

OF NEW YORK, N. Y., A CORPORATION OF NEW.YORK. 1

INSULATED BAIL-JOINT.

To all whom it may concern:

Be it known that I, BANCBOFT G. BRAINE, a citizen*of. the United States, residing at Brooklyn, in the county of Queens and State of New York, have invented certain new and useful Improvements in Insulated Rail- Joints, of which the following is a specifica tion.

This invention relates to that class of insulated rail joints embodying a two part or seetional supporting base for the rail ends whereby a separate individual supporting base section is provided for'each rail end, admitting of such a disposition of the insulation that there is no insulating material which is required to carry the load or weight of the trains.

As a principal object, the invention has in view certain structural improvements in a joint of the character referred to intended to secure a satisfactory and effective reinforcement of the joint throughout. To this end the invention secures such a reinforcement of the side joint bars as to obtain a strengthening of the joint at the center, thus resisting any tendency of the joint to give way or rupture at the weak point, viz: at the central point between the ties upon which the joint is supported.

Furthermore, the invention contemplates an improved construction providing what may be characterized as cushioning side bars or girders for the 'oint fastenings, and which serve to absorb lateral shocks and strains imposed on the joint 'and joint fastenings, thereby more effectually maintaining the joint in a tightened condition.

A more general object of the invention is to improve the reinforcing and stiffening of the joint While at the same time preserving the characteristic feature of providing each joint bar along one end portion thereof, with i view, which will more readily appear as the nature of the invention is better understood, the same consistsin the novel construction,

' combination, and arran ement of pa'its'hereinafter more fully described, illustrated, and

. claimed.

-' The essential features of the invention Specification of Letters Patent. Application filed May 24, 1907. Serial No. 375,509.

Patented Aug. 11, 1908.

above indicated are necessarily susceptible to a variety of structural modifications without departing from the scope thereof, but certain referred embodiments of the invention are s own in the accompanying drawings, in which- Figure 1 isa perspective view of a rail joint, of the general Weber type, constructed in accordance with the present invention. Figs. 2 andS are separated perspective views, respectivelyof the opposite shoe members of the joint. Fig. 4 is a bottom plan view of the joint. Figs. 5, 6, and 7 are cross sectional views, respectively on the lines 55, 66,.and 7-7 of Fig. 4. Fig. 8 is a bottom plan view of a modified form'of joint emodying the present invention. F1 s. 9, 10, and 11 are cross sectional views of t e joint, respectively on the lines 99, 1010, and 11-11 of Fig. 8.

Like references designate corresponding parts in the several figures of the drawin s.

' As indicated, the present invention is sp cially applicable to those types of insulated rail joints embodying a two art supporting base for the rail ends, and w erein each .side' joint bar or girder is provided along one end portion thereof with a short length base sec tion affording a support for one rail end. Hence, various forms of insulated rail joints involving saidbase construction may be provided with the special reinforcement claimed herein. This reinforcement may likewise be associated with side joint bars of various designs, irrespective of whether these joint bars constitute the upright members of joint shoes or shoe angles, or are in the form of an le bars or splice bars arranged over the rai bases and disposed beneath the rail heads. However, certain practical-embodiments of the invention are exemplified by the type of joints shown in the drawings, and the latter will now be particularly referred to.

In the illustrated embodiment of the invention shown in the group of Figs. 1 to 7,-inelusive of the dra'wings, the joint primarily embodies in itsg eneral organization the service rails 1 and 2 ,the,o posite side joint bars 3 and 4, the wooden erblocks 5 inter osed between the sidejjjo'int bars and thes i es: of the rails, and the usual series of joint bolts .6.; I In this joint, the. side joint bars 3 and, i are shown as constituting the upright members of shoe "angles, and each of the same isfpn'ovided along onejend portion thereof witha oi nt tually maintains the in various ways thereon substantially the same design, and subserve' practically the same functions as the corresponding members disclosed in a series of companion applications, to-wit: filed November 8, 1906, Serial No. 342,523; filed N0- veni her 8, 1906, Serial No. 342,524; filed Dece1nber6, 1906, Serial No. 346,643, and filed January'26, 1907, Serial No. 354,284, but a distinguishing feature in the design and construction of the side joint bars in the present invention resides in the peculiar formation of these bars to secure an effective reinforcement thereof in a manner that strengthens the joint at the center. This is accomplished by providing each side joint bar with what may be characterized as a supplemental upright reinforcing girder section designated by the reference character 8. This reinforcing girder section 8 for each side joint bar is arranged in substantial parallelism to the latter, and in effect constitutes one of the wall sections of the joint bar itself, thus providing what may be termed a double wall side bar, which, by reason of having its separate wall sections arranged in substan -tial )arallelism, and united at one edge, as

will e presently explained, has a cushioning elfer-Zt or function in connection with the joint fastenings. This cushioning function of eaclrdouble-wall side bar operates to absorb lateral shocks and strains imposed on the and joint fastenings and thereby efl'ecjoint in a tightened cond-ition.

The supplemental u right reinforcing girder 8 of each side joint bar may be formed in the process of manufacturing the latter, but one practical and. ecumenicalmethod of providing this construction is shown in the group of Figs. 1 to' 7, inclusive, and consists in utilizing, in each bar, that portion of the base piece which is cut out to leave the individual rail supporting base sections 7 I of the bar. .In other words, in this method of constrimtion, that portion of the base which is cut from the end portion of the bar having'no rail supporting ase section, may be bentor folded upward-alongside of the main upright portion ofthe side bar to provide the said reinforcing girder section 8. In this way the 'materialis fullv econoinized besides producing the double-Wall side bars which are thus greatly reinforced, and particularly provide for "a strengthening of the joint at the center. Furthermore, in forming the upright girder sections-8; bending the same upward from a section of the base.

piece of thebar, the girder section of each along one end portion girder section 8 into upright position provides for a relative spring action between the girder section 8 and the joint bar which spring action secures the cus effect above referred to.

In addition to the reinforcement necessarily provided at the. bottom edges of the side joint bars by the bends or bights 9, each )roper, loning of said joint bars may be further provided at their bottom edges with the reinforcing foot flanges 10 which may also be utilized for the usual spiking purposes. Another feature to observe in connection with the special rein l'orcement described, is that it may be necessary to provide' only one end portion of each side joint bar with the supplemental girder section 8, preferably that end portion having no rail supporting base or base section as shown in the entire group of Figs. 1 to 7, inclusive of the drawings. However, a modification of the above idea is suggested in the group of Figs. 8 to 11, inclusive of the drawings. This modification not only involves the feature of constructing each side bar with a double wall or upright girder re- I inforceinent throughout its entire length, and hence throughout the entire length of the joint, but also presents the idea of making the'opposite 'shoe.members from bent plates in which the supplemental upright reinforcing girder sections 8 are bent downwardly, at the bends or .bights 11, from the top edges of the joint bar proper. In other respects, the modification shown in Figs. 8 to 11, inclusive of the drawings, is'the same in. construction and effect as the joint illustrated in Figs. 1 to 7, inclusive of the draw ings, so similar reference characters will apply to similar parts in the said separate groups of figures.

In both forms of joint described, any suitable insulating eX edients may be utilized to complete the insulation thereof, such for instance as the insulating end post 12 interosed between the rail ends and extended at its base to lie between the separate su portingbase sections 77, and insulating s eeves or bushings arranged in the holes in the rail Webs and receiving the joint. bolts therethrough. These insulating features, however, may be varied without in any way affecting the present invention, and it will also be understood that various other modifications in the structure claimed may be resorted to without departing from the spirit'or sacrificing any of the advantages of the'invention.

I claim:

1. In an insulated rail joint, the service rails, opposite joint bars each of which is provided with a base section and with an upright supplemental girder section extending beyond said base section, and insulating means.

2. In an insulated rail joint, the service rails, side joint bars each of which is provided with an upright double wall and with a short length base plate affording a support for one rail end, and insulating means. 3 In an insulated ra11 oint, the service rails, side joint bars each of which is rovided along one end portion with a s ort length base section afi'ording a sup ort for one rail end, and with an upright dou le Wall extending along that end portion of thebar having no rail supporting base section, and insulating means. In testimonyvwhereof I hereunto aflix my signature in the presence of two Witnesses.
