RAIL-JOINT.

Specification ofvIetters Patent.

Application med August 11, 1906.- fserisl No. 330,255.'

To *allwhiom it may concern:

Be it known that I, BANcRor'r GJBRArNna citizen of thejUnitedS-tates, residing at New York city, inthe and has special reference to an improved principle of construction applicable to various types of rail joints 1 and providing what may be vcharacterized as a binding 'means for interposed or inserted surface-plates suchv as insulation platesemployed in insulated rail joints, or bonding plates such as employed in conjunction with rail joints fitted or equipped with a railbondng means.

lTo this end the invention primarily contemplates a novel and eiective binding means for insulation or bonding plates which provides for firmly and tightly securing such plates in intimate contact with the opposing bear-ing surfaces of the rail and the rail joint Also, this phase of the invention involves a construction which not only has the function of binding or fastening an insulation or bonding plate in its proper applied position, but which Valso possesses specialutility as a practical structural erpedient fo'r tightly wedging an insulation plate or sheet permanently in its proper'position and effectually prev venting insulating material from flowing under load 'strains or otherwise working out of .position as is the vcase at times with some types oi insulated rail joints.

In carrying out the invention, aside from the 'genL eral application thereoi as a binding or fastening means .for interposed or inserted plates of'any character, the

same provid'esa construction which is specially' applicable. asan improvement to that standardized type of insulated rail joints 'now known to railway engineers -as 'the continuous insulatedjoint vand whichis exemplified by the former patents to the applicant, viz:v

# 731,016, dated June 16,1903 and 779,066, dated January 3, 1905, and also by the patent, to'Fearey',

1# 582,907, dated May 1S, 1897v and alsouby Patents Nos. 782,645 and 7 97 ,490.,` Although of practical utility inconnection with this special type oi finsulatedjrail joint, 'the inventionis necessarily applicable 'to any type of joint` wherein it'is desirable to secure the results contemplated by the'oregoing objects.- A

With these and many `other objects in .view which will readily-appear to those familiar with the art as the ,I nature of. the invention is better understood, the same consists in the novelconstruction, combination, and

arrangement of parts hereinafter' more fully described,

' illustrated, and` claimed. A

The essential features of the invention involved in the relation o the angles ofthe opposingbearingfaces of the rail and the rail joint members or plates, isnecz a,timmtlie'rails AfA and the opposite l continuous `side essarily susceptible to a wide range of plates, y'whether in short sections or flcation and also to a wide range 1of application to variout types of joints, and various combinations. without departing irom the scope of the invention, certain preferred embodiments o'f which are suggestedV in the accompanying drawings, in which:

Figure l is a sectional perspective view of a rail joint 'of the continuous type embodying binding means contemplated by the present inventiom Fig. "2 is an enlarged cross sectional view ofthe same type of joint, showing one of the side angle plates drawn tight against side of the, joint shown with theiparts slightly separated and illustrating how the surface plate may-be of 654 the interposed or inserted surface plate and opposite' substantially uniform thickness instead of corresponding in taper to the wedging or tapering spaces between Fig. 3 is a cross sectional 'view similar to Fig.- 2 showing the opposing faces of the rail and the rail joint member.'

the provision of a positive gripping surface on the bearing face of one or more of the bearing faces ofthe'rail joint members for more effec'tuallyl pinning ber or bond in position. Fig. -4 is a cross sectional view showing the lapplication 'of the 'improvement to the plain. angle bar type of rail joint.

Like references designate corresponding parts in the several gures of the drawings. l j

In carryingout the present invention, no change is required in the general organization of the parts of anytype or' rail joint to `.which the' saniemaff be applied, nor any radical departure necessitated in the structural features oi such jointpas the improved'feature oi construction which provides a deniteand positive bind# ing means for interposed or inserted plates such-as insulation plates or bonding plates is necessarily'applicable to any type oi rail joint utilizing surface plate of this general character. Furthermore, the binding or pinning means provided by the present invention may be utilized in a variety of .ways and in dierent positions or locations as a-fastening for insulation plates or bonding whether detachable or permanentlypositioned. lilVhile susceptible to this widerange of application and t'uncfull length, and .I

tion, the invention, however, possesses special utility as abinding or pinning. means for insulation .plates and-is hence of special and. practicalvalue in connection with insulated rail joints. In this phase, the invention also provides certain novel and improvedfunctions in con@ y nection with that type of insulated rail joints characterf ized by railway engineers as the continuous rail joints and exemplielror instance, in the applicafitsformer patents,hereinloeore referred to, so for. illustrative purposes, the preferred embodiments of .the invention are shown in Figsyl', 2, and 3 of theidrawings. Inthese figures the railjoint illustrated is of the continuous type referredto and essentially includes in its general organi- A y ing face 3 opposing the corresponding inclined bearing face 4 at, the under side of the rail head 5. Also, each v of said continuous side plates 1 is formed at the lower edge of its vertical member with aninclining foot flange 6 lying over the rail base and provided at its under side with an inclined bearing face 7 opposing the corresponding bearing face 8 on the upper side oi the base liange 9 of the rail. 1n addition to these features, each continu- 'ous side plate l. of the type of joint referred to has extended from and below the outer edge oi its foot {lange- 6 a base flange extension 10 occupying a substantially horizontal position and lyinor beneath the base flange oi' .the rail. The said base flange 10 of the side plate is provided at its upper side with a bearing face 1l opposing the corresponding bottom i'ace l2 of the rail. ln the insulated con tinuous rail joint of the type herein described, an insulation plate or sheet13 is interposed between the opposing faces of the rails and the side angle plates 1. These insulation plates or sheets 13 are usually-of a continuous form and not only face the sides of the rail joint, but are also formed with top flanges 14 lying between the upper bearing faces 3 ofthe side plate and the under bearing face 4 of the rail head and with foot-pieces between faces 7 and 8. Also, the insulated plate or sheet 13 is provided with a base piece 16 lying between the bearing faces 11 and 12.

vA distinguishing feature of the present invention re- Isides in the expedient of making one or more of the an gies of the bearing faces of the rail joint plate oi" a greater degree than the angles `of the-corresponding bearing faces of the'rail, thus forming a binding or fastening wedge which serves to securely Vpin the interposed or inserted plates in a fixed position -and prevents the same from creeping or working out of place as is sometimes the case in connection with insulation plates. In

this particular function it should be noted at this point that the top flange 14 of the insiilation plate 13 sometimes has a tendency to work outward'between the opposing bearing surfaces 3 and 4, whereas, according'to the present invention, the wedging action of the bearing face 3 positively prevents this result and therefore retains a more perfect and desirable insulation of the joint. I A

The result referred to is accomplished by having the angles of the bearing faces of the rail joint members different ironi the angles of the corresponding rail faces, although it will be observed from the drawingsthat in the preferable construction they angles of the bearing faces 3, 7 and 11 are greater than-the rail faces opposing the same and are disposed in directionsto secure a similar wedging action upon the members 14, 15, and 16 of the insulation when the side or joint plates are tightened up.

Of course, the wedging feature on the joint plate may be applied to one or more points according to the type resaca have the pinned portions of the surface plate 13 of a tapering thickness, yet the invention may be carried.

out by having such portions of the saine thickness as suggested in Fig. 2. Again, if desired to secure a more effective pinning action, one or more of the bearing faces of the joint plate may be concaved as indicated at i7 in Fig. 3 ot the drawings, to provide a-positive gripping snrface upon said bearing.

To illustrate the range of applicability to different types of joints, there is shown in Fig. 4 of the drawings a plain angle bar type of insulated rail joint including in its construction the side'angle bars 18 having the upper and Alower bearing faces 19 disposed at a greater angl e than the corresponding bearing faces 20 of the rail R and cooperating withv the flange portions 21 of the inf sulation plate or sheet 22 in the saine manner as herein' described. i

I claim:

1. In a rail joint, the rails. opposite separated horizon- =tallymovalile independent joint members, each having a hearing face disposed at a greater angle than the corresponding rail face, and a plate element pinned between said opposing faces.

2. In a rail joint, the rail having a plurality of bearing faces, and a rail joint member likewise havinga plurality of bearing faces disposed at a different angle from those of the rail, and plate elementspinned hetween said faces.
