MORRIS S. TOWSON, OF CLEVELAND, OHIO, ASSIGNOR TO THE LOVE ELECTRIC TRACTION COMPANY, OF CHICAGO, ILLINOIS.

RAlLwAY-YoKE.

SPECIFICATION forming part of Letters Patent No. 490,690, dated January 31, 1893.

y Application tiled October 10, 1892. Serial No. 448,385. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, MORRIS S. Towson, a citizen of the United States of America, residing at Cleveland, Cuyahogacounty, Ohio, have invented certain new a nd useful Improvements in Railway-Yokes, of which the following is av specification, reference being had therein to` the accompanying drawings.`

This improvement relates to lyokes designed more particularly for electric railways, but may also be used in other forms of traction.

The invention will be hereinafter more fully described and then definitely claimed.

In the accompanying drawings-Figure 1 is an elevation of one side of ayoke with the track and slot rails in positionthe rails -being in section. Fig. 2 is a detail of the fastening of the slot rail on a larger scale, partly broken away. Fig. 3 is a plan of the same on the same scale also with part broken away.

Referring now to the details of the drawings by letter-A indicates the yoke (only one-half being shown) having a web B and stiftening flanges C at its edges. At each outer extremity of the yoke is a seat for a tram rail D, consisting of a hollow live-sided tube or boxE having its upper surface (which forms the seat for the rail) horizontal and two of its sides inclined. The upper corners of this box are slotted as shown at e. Upon the top side is seated the tram rail D, which is secured by two hook-headed bolts F passing through the slots e and holes e formed in the boX. These bolts set substantially at right angles to each other and are secured by nuts G and nut-locks I-I in a manner well under against each other and are not likely to bestood. It will be obvious that this means of securing the rail is a very secure and convenient one-secure, because the bolts act p into the nut K. At the side of this projection J, a box M is formed having a cover or cap N fitting therein.

Three of the sides of this cap extend downward so as to restl upon the bottom of the box'.

which can easily be done as, owing to the corresponding shape of the recess and nut, the latter can not turn in the former. To prevent the bolt turning, a spring washer or nutlock O may be employed. The holest' and j should be a fair fit for the bolt L, as when this is the case, owing to the inclined face of the projection andthe corresponding incline of the inside edge of the rail as shown at e, the screwing of the bolt home will force the rail tightly against its seat. Iffound necessary in adjusting the width of the slot, as may sometimes be required owing to imperfections in casting the yokes,a liner may be inserted at e by which means the slot may be widened. By the above arrangement, the slot rails may be readily taken up at any time and as easily returned and secured to their place. f This is a necessity in electric roads and my arrangement will therefore be found very convenient for this purpose.

In some cases, instead of using the recess j and nut K, the hole j may be tapped and the bolt L screwed directly into said hole, but I regard the use of the nut as the preferable plan. j

At P are shown recesses to receive the ends of the paving plates Q and at R holes are made for insulator rods, but as these form no The fourth side, that nearest the slot rail, does not extend down- Y part of the invention here claimed, no furl ther reference to them is necessary.

What I claim as new is: l

l. The combination with a rail having a depending flange, of a yoke provided with a projection J to receive said rail, and a bolt IOO depending flange and with a yoke provided with a projection J, having a recess j and holej, of a nut set in said recess and a bolt passing through said flange and into the nut, substantially as described. y

3. A railway yoke provided with a projection forming a seat for a slot rail, a hole to receive the threaded end of the securing bolt', a box for receiving and protecting the head, and a cap closing the top of the box, substantially as described.

4. A yoke for an electric railway, provided with a projection to receive a slot rail,a substantially horizontal surface forming a seat for the trani rail, perforations constructed to receive securing bolts substantially at right angles to each other, and inclined surfaces beneath the seat to receive the pressure of the bolt nuts, substantially as described.

5. An electric railway yoke provided with projections to receive the slot rail, and seats for the tram. rails, each seat comprising a hollow box E having a substantially horizontal surface forming a seat 'for the rail, and two inclined surfaces beneath said seat, said box being perforated to receive bolts substantially at right angles to each other, substantially as described and shown.

In testimony whereof I affix my signature in presence of two witnesses.
