SAFETY RAIL CI'QINT.l

Application filed February 19,1923. `Serial No. 619,870;

T o all whom t may concern Be it known that we, lVALTnn Dna and HENRY RIEFSGHNIDER, citizens of the United States, residing at Seattle, county of King, and State of /Vashington, have in vented new and useful Improvements in` Safety Rail Joints; and we do hereby declare that the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to.

make and use the same.

The invention is a means for connecting yrails that will make it impossible for them to become disconnected or to bend at the connection.

The invention is an improvementkover the joint shown and described in our Patent No. 1,439,191 issued December 19; 1922.V

The object of the invention is to provide rails with ends which will dovetail together so that it will be impossible for them to spread without tearing up the entire track,

Vith these ends in view the invention embodies a rail with the topof the rail omitted a short distance from the end, its web thickened with the sides tapering; and another rail with angle plates extending beyond the end of the railv and integral therewith; and a slot with tapering sides between the angle plates. The invention also embodies a clamp for holding the ends of the rails up into the slots of the other rails.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein: 1

Figure 1 is a side elevation with parts broken away.

Figure 2 is a cross joint.

Figure 3 is a view showing an alternate design of the clamp at the bottoni of the joint.

Figure 4 is a similar view showing another alternate design of the clamp.

Figure 5 is a bottom View of the female member. j

Figure 6 is a perspective view of the male member.

In the drawings we have shown our joint as it would appear in use in Figure 1 wherein numeral 1 indicates one rail on which is the female oint and numeral 2 indicates another rail the end of which constitutes the male member. The web of thev rail 2 is thickened from the point 3 shownin Figure section through the RrnrsoHNi- Y V1 rand tapers? from its upper edge 4 toits lower edge 5` where itA is curved. This web fits into a slot 6 in the center of the rail 1 and extends to the point 7 shown in Figure 1.` On the sides ofthe rail 1 are

plates

8 and 9 which extend beyond the end of the rail and to the point 10 so that atleast two bolts` as indicated by the numeral 11 may be placed through the yjoint on each side of the point 3.

The construction of the rail lmmay be p more clearlypunderstood from the bottom view shownin Figure 5k which shows the top of the rail stopped or cut away at the line 3, the bottom flange ofthe yrail` stopped or cut away at rthe line 12, the slot 6 which'- extends from the line12to the point 3 in the center of the rail, and the

side plates

8 and 9 which extend from the line 12 to the point 13. The lower edges of the

side plates

8 and 9 extend outward to form

flanges

14 and 15 which rest upon the bottom flange ofY the Vend of the rail 2. The construction of the end of the rail 2 as shown in Figure 6 shows the top of the rail stopped orcut away at the point 3, the webthickenedand tapering from the point 4 to the point 5, and a portion of the web beyondlthe point 3 thickened so that it will be flush with the sides of the top of the rail as indicated by the numeral 16. Suitable holes k17 maybe placed through the web to correspond with similar holes through the iiangesor side plates of the rail 1 so that bolts may be 'placed through them to hold the joint together.

At the'bottom of the section shown in Figure 2 is a clamp 18 which may be constructed as shown, or in one piece with projecticns 19 extending upward and bent over as shown at the points 20, and projections 21 extending outward through which the clamp may be spiked to the ties. In the design shown the clamp is shown in two halves so that one half may be slipped on each side of the ont. The halves may then be held in place by spikes passing through the projections 21. Or the clamps may be made in one piece and placed over the ends of the rails before the joint is assembled. An alternate `design of the clamp is shown in Figure 3 which has a projection 19 on one side and a lug` 22 on the other so that it may be passed under the rail; raised to the position shown,r and then held in place by spikes. ln the design shown in Figure 4 the clamp has a projection 19 on one side and a lug 23 onthe other in which is a Ydove-tail slot 29k, A member 25 with "a dove-tail projection 26 on it and whose upperend is bent similar to 'that ofthe projection 19 maybe placed in T'Another may be lin the number of bolts used ofthe members-of the in KAeither section of VtheV joint. k(And still another change may be in the shape of any joint, orV in the design of the clamps;r

. The construction? will begreadily understood from theforegoing description, as all yrails, maybe made with one end similar to that ofrail4 l andy with the other similar to that offrail'2 so that when a track is being laid one'rail will fit yintov another and the ktwo bolted together. Yjoining the rails in- -It will be seen that by this manner it will be' absolutely impossible for them to come apart even though the boltsinay loosen. n

Having thus fully described the invention what we claim as new and'desire to secure by Letters Patent, is

In a rail joint a rail section having its fiange terminated short of its end, the web removedbetween the end of the Hangs and the end of the rail and replaced by side plates, whichextend from a point a short distance behind the point at which the ange terminates to a point beyond the end of the topof the rail, and which have outwardly extending flanges at their lower edges; a companion rail section provided with an enlarged web section and its top terminated a short distance from its end; the enlarged web .section and side plates being provided with bolt holes by which the joint may be bolted together; and base plates with extensions projecting upward that c'lalnp the two sections together, and that may be held'tothe ties by spikes.
