fr) all whom, t potty concern:

Be it known that 1, BENJAMIN WOLHAUP- TER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Joints; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved con-v struction in rail-joints of that class having joint plates or bars which fit against the sides of the rails and are held in contact therewith by track-bolts, so as tohold the adjacent ends of the rails rigidly in alinement with each other.

The invention consists in the matters hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, illustrating my invention, Figure l is a plan view of a rail-joint embodying lmy invention. Fig. 2 is a View in side elevation thereof. Fig. 3 is a cross-section of the joint, taken upon line 3 3 of Fig. 2. Fig. 4 is a perspective view of the base-plate shown in Figs. 1, 2, and 3 removed from the other parts. spective view of the joint-bar at the outer y side of the rail or joint. Fig. 6 is a sectionalv view similar to Fig. 3, illustrating a modified form of construction in the outer joint-bar.` Fig. 7 is a like sectional view showing still other forms of construction in both the inner and outer joint-bars. Fig. 8 is a perspective view of the inner joint-bar shown in Fig. 7'. Fig. 9 is a perspective view of the base-plate used in connection with the form of inner joint-bar shown in Figs. 7 and 8. and ll are sectional'views of an old or wornout rail and of a blank for making joint-bars, the latter being shown'in an intermediate stage of the process vof making it. Fig. l2 is a sectional view of a rail-joint, showing the form of construction `in which the base-plate and the outermost joint-bar are made integral with each other. Fig. 13 is a view in cross-section of still another form of joint in which the base-plate is likewise made integral with the outermost joint-bar.

First describing the. form of construction Fig. is a per-f Figs.

serial No. 116,765. (No man.)

' illustrated in Figs. 'l to 5, both inclusive, A A

indicate the adjacent ends of ordinary trackrails, the same comprising a head a, a web a', and base-anges c2, the upper surfaces of the base-flanges c2 and the under surfaces of the head a being provided with angular faces inclined at angles to the perpendicular. The web a is shown as provided with one or more transverse bolt-apertures a4, arranged in the usual manner. Bis a base-plate,which in the instance illustrated is made somewhat widerthanV the width of the bases of the rails which rest thereon. Said base-plate is made longitudinally corrugated in form for the purpose of giving sti'- ness to the plate and to afford elevated bearing-surfaces to support the rails and intermediate grooves or depressions to receive sand, grit, or cinders, and thereby prevent the retention of the same between the base plate and rails and consequent wearing away of the parts. The said base-plate, as shown in the accompanying drawings, is provided with flat elevated relatively wide portions b b', which come beneath the side margins of the base-{iangcs of the rails, and with an intermediate corrugated portion forming a plurality of flat top bearing-surfaces b2 b2, located in. the same horizontal plane with the upper surfacesof the marginal parts b b and forming also dat bottom bearing-surfaces b3 b3, which bear against the top surfaces of the ties on which the base-plate` rests. On its inner margin the marginal part ot' the plate is eX- tended downwardly and then horizontally outward to form a marginal flange b4, the bottom surface of which is in the same horizontal plane with the bearing-surfaces b3 3 and which also rests upon the ties. At the outer margin of its outer elevated part b the tie-plate is provided with an upwardly-extending iiange or rib b5, which forms a shoulder against which the outer edges of the baselanges a2of both of the rails rest orv bear. At its opposite or inner part the tie-plate is provided -with spike-holes h6 h6, through which ordinary railway-spikes F F may be Ydriven into the ties on which the base-plate rests.

The spike-holes b will be so located that when the rail is placed in position upon the base-plate with the outer margins of the railfianges abutting against the outer longitudi- ICO nal rib or fiange b5 the other or inner railanges will be of such distance from the outer margins of the spike-holes as to admit the thickness of the spikes, the latter thereby forming keys by which the rail is held firmly against said rib b5.

C indicates the inner joint-bar, which, as shown in the figures, is of familiar construction,the samehaving inclined top and bottom bearing-surfaces adapted to engage the angular faces on the under surface of the head a and on the upper surface of the base-flanges a2 of the rails. Said inner joint-bar is shown as having the form of an angle-bar, the same being provided at its lower margin with an inclined fiange c', which extends outwardly over the inner base-fiange of the rail and is notched at its edges for engagement therewith of the spikes F F, the heads of which bear against the top surface of said flange.

D designates the outer joint-bar, or that which is applied to the outer faces of the adjacentendsof the rails. Said joint-bar consists of a central part orweb d and top and bottom longitudinal members d d2, the bar thus formed constituting, in effect, a girder of' which the web d constitutes the connecting member and the top and bottom members d' d'2 the upper and lower chords. The upper member d' of said bar D is adapted to bear against the outer face of the head a, and the lower member d2 is adapted to engage the outer hase-flanges of the rails. The said lower member d2 is, moreover, provided on its inner face with a longitudinal groove or recess d3, adapted to receive the margins of the base-flanges of the rails, the said longitudinal groove or recess d3 in the instance shown being formed by means of a longitudinal ange d4, which projects inwardly over the top of the base-Hanges, and another inwardly-projecting flange d5, which projects inwardly beneath the bottoms of the railfianges. As shown in said Figs. 1,'2, 3, ft, and 5, the lower-most tiange d5 extends beneath and bears against the horizontal marginal part b of the base-plate B, which part b, together with the margins of the baseflanges a2, enters the groove cl3. The bottom surface of the lower member (Z2 of said bar D is provided with au outwardly-extending fiange (t7, which projects horizontally outward from the web dand which is provided with notches ds to receive the holdingspikes F F' at the outer side of the joint. Said lower member d2 is, moreover, made fiat and horizontal on its lower surface, so that it is adapted to bear upon the top surface of the ties which support the same. The inwardly-extending flange di will be made of vertical thickness equal to the space or distance between the bottom of the elevated part b of the base-plate and the top of the tie, so that said marginal part of the baseplate rests upon and is supported by said bottom flange (Z5 and -in turn supports the outer part of the base-flanges of the rails which rest on said marginal part of the baseplate.

The upper surface of the groove d3, which receives the base-fianges of the rails, is inclined or beveled to correspond with the inclination of the upper surface of the said base-flanges, so that when the lower part of the bar D is drawn or forced toward the rails and the base-plate by the tightening of the track-bolts the base-anges will be tightly wedged or clamped in the groove and a rigid connection thereby made between the rails and the joint-plate D. Moreover, inasmuch as the margin of the base-plate enters the groove d3 with the rail-flanges, the base-plate is firmly clamped against the rails by the action of the oppositely-inclined walls of the said groove.

In the particular construction shown in Figs. l to 5 the upper member d of the bal' D has the form of an inwardly-projecting horizontal flange, and the web part d or portions of the bar between the upper member d' and the base member d2 is inclined downwardly and outwardly from its upward to its lowest part. The said plate D is provided with bolt-apertures d, through which pass the connecting-bolts E, by which the two joint-bars C and D are clamped to the adjacent rails.

In assembling the parts of the joints made as described the tightening of the nuts on the bolts E serves to draw the inner joint-bar C into close contact with the beveled surfaces of the head and base flange and at the same time operates to force or draw the outer bar D inwardly against the rails, so as to hold the upper member d' firmly in contact with the outer faces of the rail-heads and to draw the lower part of member d2 into clamping contact with the base-flanges and the outermargin of the base-plate on which the same rest. As the lower member is drawn toward the base-flanges of the rails in tightening the parts of the joint, the entire joint-bar will by reason of the contact of the inclined upper wall of the groove d3 with the inclined top of the base-flange rise with respect to the rails, the upper member of the bar which rests in contact with the outer surfaces of the railheads being free to slide or move upwardly on the rail-heads as the bar thus bodily rises. The innermost holding-spikes F in this construction eugage the spike-holes b b, so as to hold the base-plate from outward movement on the ties, and by reason of the presence of the flange or rib b5 on the base-plate against which the outer edges of the railfianges bear any outward movement of the rails is prevented, not only by the spikes F, which engage the outer joint-bar D, but also by the said spikes F, which engage the inner edges of the base-flanges.

In Fig. 6 is shown a joint like that illustrated in the figures above described, with the exception that the outer joint-bar D in this instance has at the upper margin of its ICO web portion d in addition to the inwardlyprojecting flange d', which comes in contact with the rail-heads, an outwardly-projecting Y flange d8, thus giving generally a T form to the upper part of the said bar and an I form to the bar as a whole. This form in the outer joint-bar D may sometimes be preferred, not only as giving a more stiff or rigid bar, but because a bar of this form may be more readily rolled from old track-rails, as will hereinafter appear.

Fig. 7 shows still another form of rail-joint, generally resembling that shown in Figs. 1 to 5. As shown in said Fig. 7, the outer jointbar D2 is made like that shown in'Fig. 6, with the exception that the entire bar is made heavier or thicker and the upper member especially is more massive, while the flanges d' d extend a less distance inwardly and outwardly from the upper Amargin of the web. As shown in said Fig. 7, moreover, provision is made for aording engagement between the lower margin of the angle-bar C and the baseplate B in such manner as to hold these parts from relative longitudinal movement, these features being more 'clearly shown in detail views Figs. 8 and 9, which show in perspective the said angle-plate and base-plate. The interlocking connection referred to'is afford# ed by means of a depending flange C' on the angle-bar C, said depending flange extending downwardly outside of the base-flange of the rails and being shorter than the angle-bar. The ends of said flange are adapted to engage transverse shoulders on the base-plate, which shpulders, as indicated by U b, are formed by cutting away the inner marginal part of the base-plate in a manner clearly shown in Fig. 9. The depending liange C is shown as depending from the central part of the bottom flange c of the angleeplate, while` the notch which forms the shoulders 737 57 is located at the central part of the base-plate and between the spike-holes h6. As a further improvement in connection with these features of construction iu the angle-plate C and base-plate B, I provide the depending flange C with an inwardly-extending horizontal marginal flange c2, which extends beneath andinterlocks with an inner marginal part b of the base-plate, which, as before stated, is elevated above the bottom surface of said base-plate, which rests upon the ties, and is made relatively wide for the support of the inner margins of the base-anges of the rails. The engagement of the horizontal flange c2 with the inner margin of the base-plate serves to hold the said inner margin of the base-plate in contact with the rails.

Figs. 10 and 11 illustrate the process lof forming or rolling the joint-bars D from old track-rails, G in Fig. 10 showingin reversed position a rail from which the bars are to be rolled and H indicating a blank for a jointbar in an intermediate stage of the process of its formation. Fig. 1l illustrates the blank from which will be formed a joint-bar like` that shown in Figs. 6 and 7, the same having a double-flanged upper member or head. In the construction of such a j oint-bar it will be readily apparent from an inspection of Figs. 10 and 11 that the heads of the rails may each be converted into the lower member of the joint-bar by shifting the metal of one side of the head so as to form a longitudinal groove in one side thereof to correspond with the groove Ligand a iiange at the other side thereof to correspond with the ange d7 and by modifying the form of the base-flanges of the rail,

so that the same may constitute the flanges d/ d of Figs. 6 and 7.

In forming from old rails a joint-bar like that illustrated in Figs. 1 to 5, wherein the upper member of the joint-bar has an inwardly-extending iiange only, it will be preferred to sever one of the base-flanges of the rail along a line indicated by g g on Fig. 10, after which the rail can be readily converted by rolling to the form shown in Figs. 1 to 5.

In Fig. 12 is shown in cross-sectional View a form of rail-joint embracing the main fea` tures of construction above described, but in which the outer joint-bar is made integral with the base-plate or, in other words, in which the bar as a whole is made of angular form and the lower flange of the outer bar `beneath the V-shaped groove therein is extended beneath the rail-base and constitutes a base-plate for the joint.

As shown in Fig. 12, D3 indicates the outer joint-bar, which is of the same general form as shown in Figs. 1 to 5 and is provided with a wide inwardly-extending iiange B', which is wide enough to reach past the inner margins of the rails and is provided with spikeholes to receive holding-spikes F. In the instance illustrated in said Fig. 12 the horizontal part or flange B', which constitutes the base-plate, is made flat on its upper and lower surfaces and is adapted to rest upon the top surface of the ties and to have continuous bearing on the bottoni surfaces of the rails. The outer part or member Ds is provided with an upper horizontal member formed by an inwardly-extending ange d', like that shown in Figs. 1 to 5, and the lower part of the said part D3 is provided with an inwardly-extending flange d4, the lower surface of 'which is downwardly and outwardly inclined or beveled to correspond with the inclination of the upper surface of the outer base-flange of the rail, like the corresponding fiange in Figs. 1 to 5. The V-shaped groove formed between the said flange d4 and the base plate or flange B in this instance, however, is made wide enough only to receive the margins of the j oint-plate instead of bein g substantially fiat,

as shown in the figures before described, is

made of outwardly-curved, arched, or convex.

form. This feature has the advantage that when the track-bolts are tightened the web will by reason of the slight flexibility of the web yield inwardly to a slight extent or, in other words, approach a flat form, and will thereby tend to maintain a constant pull or tension on the track-bolts, by which all of the parts of the joint will be held firmly in contact with each other. Moreover, when the web is thus made of curved or arched form the use of nut-locks on the track-bolts maybe avoided, as the elasticity of the arched web will always hold the nuts firmly in contact with the inner joint-bar. In Fig. 13 is shown a similar joint-bar of angular form having an outer member D4 and a horizontal bottom member B2. In this instance the web portion of the member D4 is brought near the vertical plane of the outer face of the railhead, and its upper longitudinal member has the form of an outwardly-extending flange 19, While its lower member is formed by a like outwardly-extending flange d10, which correspends in location with the flange d4, before described, and is joined at its outer margin to the outer margin of the base-plate B2, the groove to receive the margin of the rail in this instance being formed by and between the said outwardly-extending flange d10 and the horizontal flange B2.

As shown in said Fig. 13, the inner jointbar has the form of an angle-bar or is provided with a lower flange C', which extends outwardly over the inner base-fianges of the rail.

The operation of the combined base-plate and outer joint-bar (shown in Figs. 12 and 13) is generally the same as the form of bar shown in Figs. 1 to 5, inclusive-that is to say, the V-shaped groove formed at the lower part or base of the outer joint-bar has clamping engagement with the base-flanges of the abutting rail ends, while the inwardly-extending flange constituting the upper member of the joint-bar bears against the side faces of the rail-heads and is free to move vertically thereon when the edges of the base-flanges are forced into said groove by the tightening of the rail-joint.

A general ad vantage gained bythe employment of a joint-bar of the girder form described is that of affording a joint having a great amount of vertical and lateral strength with a minimum amount of material.

An advantage gained by the employment of an outer joint-bar of girder form, the upper member of which rises to and bears against the outer face of the rail-head and the lower member of which extends beneath the base of the rail, is that a joint-bar thus made by reason of its great vertical depth possesses a great degree of stiness and capacity to withstand bending strains brought thereon by the rail ends, which are engaged therewith, under the stress of loads coming upon the ends of the rails and tending to depress one of them with respect to theV other or throw them out form of outer joint-bar described, whereby f the lower member of the same bears or rests upon the tie and its upper member bears against the rail-head, is that a joint-bar thus made constitutes a brace extending from the outer side of the rail-head downward to the tie at a point outside of the base of the rail and tending to brace or hold the rail-head from being thrust outwardly.

An advantage arising from the employment of a deep joint-bar having a wedge-shaped groove in the lower or base portion of a jointbar is that the longitudinal groove, having opposing inclined surfaces between which the outer edges of the base-flanges of the rails enter, serves to clamp or confine the said basefianges by a wedging action in the same manner as an ordinary joint-bar, such as is indicated by C, engaged the opposite inclined surfaces of the head and base flanges of a rail. In other words, the construction described provides a joint-bar which has clasping engagement with the base-flanges of the rail, while at the same time it is of such great vertical depth or width that it has a stiffness and capacity to resist vertical or downwardlyacting stresses much greater than that of a fish-plate or joint-bar which fits between the base-flanges and head of the rail. It will be further obvious that the parts of the joint made as above described are adapted to fit track-rails of varying weights or in which the base-flanges are of varying thicknesses by reason of wear of the rolls used in their manufacture, it being obvious that slight difierences in the sizes and relative proportions of the parts of the rails will make no difference in the operation or fit of the parts. This will be manifest, so far as the outer plate D is concerned, by consideration of the fact that a difference in the thickness ot' the baseflanges of the rails will merely result in the same entering a groove d3 to a greater or less extent and that the position the upper member or flange d' bears against the outer face -of the head of the rail may be varied vertically to some considerable extent without effecting the operation of said plate D. A flanged joint-bar, like the outer joint-bar D, made in the manner described, has the advantage when employed in connection with a base-plate, such as is shown in the figures above referred to, of clamping or holding the outer margins of the base-plate firmly in contact with the outer margin of the base-flanges of the rails, which rest thereon, so as to hold said parts from relative vertical movement and to utilize the stiffness of the base-plate as a means for holding the ends of the rails in alinement with each other.

When the outer joint-bar of' girder form, provided with a tapered or V-shaped groove adapted to have clamping engagement with IOO IIO

the top and bottom surfaces ofthe outer baselianges of the rails, is employed in connection with an inner joint-bar or splice-bar, which ts between the inclined faces of the rail-heads and base-Hanges, as shown in the accompanying drawings, it is obvious that the joint-bars at both sides of the joint are equally capable of being drawn up or tightened into snug contact withthe rails, so that equally rigid connections are aiforded between the rails at the inside and outside of the latter, while at the same time the joint as awhole is made of great strength and stiffness, because of the greater vertical depth and consequent greater stiffness of an outer joint-bar when made so deep as to extend from the level of the rail-heads downwardly to the base-anges of the rails.
