RAIL-JOINT MECHANISM.

Specification of Letters. Patent.

Patented Apr. 13,1920.

AppIication filed December 5, 1918. Serial No. 342,714.

To all whom it may concern Be it known that I, MARIN Nora, a citizen of the United States, and residing in the township of North Fayette, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful Improvements in Rail-Joint Mechanism, of which the following is a specification.

My invention consists of certain new and useful' improvements in rail joints.

The primary object which I have in view is the provision of rail joint mechanism which will properly connect and support the rail ends against bending and flexing, and which cannot become loosened by the passing trafi'ic.

Another objectis the provision of rail joint mechanism which may be used in an emergency for patching or connecting together the portions of a broken rail, without requiring the drilling of holes through the rails, whereby a broken rail can be quickly patched and the interruption of traffic prevented.

In the accompanying drawings, Figure 1 is an outside elevation of m I rail joint uniting togetherthe ends of adjacent rails; 2 is a section taken along the line Il-ll in Fig, 1; Fig. 3 is an elevation of the inside joint plate; Fig. 4; is an elevation of the member which locks the rail: bolt nuts, and Fig. 5 is a perspective of one of the rail bolts.

The following is a detailed description of the drawings.

A represents the two rail ends provided with the usual bolt holes, shown as two in number on each rail end, as in the use of my rail joint such support is given to the rail ends that more than two holes are unnecessary, thus effecting a saving in boring the rails and also enabling me to reduce the material required for the joint plates.

B is the outside joint plate and C the in side one. Both of said plates are of proper size and shape to fit against the webs of the rails, and to bear against the under side of the rail heads and the upper side of the rail bases, as shown. The inner plate has oval holes 1 which register with the holes in the rails, and the outside plate is provided with registering round bolt holes. 2 represents the usual rail bolts having the head ends of their shank oval, so that when said bolts are inserted from the inside their ovals occupy the oval holes 1 in the plate C, thus preventing the bolts from turning, while theshanks of the bolts protrude from the plate B. 3 are the usual nuts screwed up on the bolts 2 against the plate 13.

The plate B is provided at its center with a depending flange 4 provided with a bolt hole 5. The plate 0 is provided with an integral bracket (3 which joins the plate at its bottom center and extends under and in close contact with the under side of the rail bases to the front where said bracket is provided with an integral depending flange 7, which fits against the inside face of the flange at, said flange 7 being provided with a bolt hole 8, preferably oval and registering with the bolt hole 5. l

D is the lock plate having a laterally ex:- tending head 9 prov ded with angular notches or apertures 10 which fit over and lock stationary the rail bolt nuts 3. The plate D has a depending central stem 11, properly curved to fit down over the plate B and against the outer face of the flange i of the plate B. Said stem is provided with.

a bolt hole 12 which registers with the bolt hole The member i) is curved to fit snugly against the plate B.

13 is a belt which is inserted rom the inside

throughthe holes

8, 5 and 12, and has screwed up on its outer end the nut ht which is provided with a squared portion for the application of a wrench or spanner and a radially serrated portion which is engaged by the pawl 15 pivoted to the member D and trailing over the nut let as said nut is tightened but positively preventing the accidental unscrewing of said nut.

It is thus evident that the bolts cannot loosen and therefore, without first knocking off the pawl 15, the rail oint cannot be rendered ineffective or be removed.

In case of a broken rail, it is evident that an emergency patch can be made by applying the plates B and C to the sides of the rail, bridging the fracture, and putting the lock member in place against the plate B, in serting the bolt 13 and screwing up the lock nut 14 which will be held against loosening by the pawl 15. Thus trafiic need not be interrupted until a new rail is'laid, but the patch will hold and support the broken rail ends in position.

lVhere my invention is to be used only as a patch for a broken rail, the joint plates need not be provided with bolt holes, but I prefer to make up the mechanism as a rail joint for general use, thus fitting it for either a rail joint or a patch.

What I desire to claim is:

1. In rail joint mechanism, the combination of a pair of joint plates adapted to be applied to the opposite sides of the rails'to bridge the joints, said plates being provided with bolt holes registering with the bolt holes in the rails, flanges depending from said plates and abutting together, bolts inserted in said bolt holes, nuts screwed up on said bolts against one of the joint plates, a member notched to fit over said nuts to lock the same, and means for clamping said member and said flanges together.

2. In rail joint mechanism, the combination of a pair of joint plates adapted to be applied to the opposite sides of the rails to bridge the joints, said plates being provided with bolt holes registering with the bolt holes in the rails, flanges depending from said plates and abutting together, bolts inserted in said bolt holes, nuts screwed up on said bolts against one of the joint plates, a member notched to fit over said nuts to lock the same, said member having a depending portion registering with said depending flanges, a bolt clamping said flanges and said member together, anut on said bolt and means for locking said last named nut against loosening,

3. In rail joint mechanism, the combination of a pair of joint plates adapted to be applied to the opposite sides of the rails to bridge the joints, said plates being provided with bolt holes for the installation of the usual rail bolts and nuts to clamp the plates to the rails, one of said plates being provided with a depending flange and the other plate being provided with a bracket which eX- tends under and in contact with the bases of the rails and has a depending flange registering with said first mentioned flange, a locking member having its upper portion notched to engage the nuts on the rail bolts and having a depending portion registering with said flanges, and means for clamping said flanges and said member together.

4:. In rail joint mechanism, the combination of a pair-of joint plates, adapted to be applied to the opposite sides of the rails to bridge the joint, said plates being provided with bolt holes for the installation of the usual rail bolts and nuts to clamp the plates to the rails, one of said plates being provided with a depending flange and the other plate being provided'with a bracket which extends under and in contact with the bases of the rails and has a depending flange registering with said first mentioned flange, a locking member having its upper portion notched to engage the nuts on the rail bolts and having a depending portion registered with 'said flanges, a bolt clamping said flanges and member together, a nut on said bolt, and means for locking said nut.

5. In rail joint mechanism, the combination of a pair of joint plates adapted to be applied to the opposite sides of the rails to bridge the joint, and engaging the webs, heads and bases of the rails, one of said plates being provided with a vertically de pending flange while the other plate is provided with a bracket which extends clear across under and in contact with the bases of the rails and has a depending flange registering with said first named flange, a. bolt inserted through said flanges to clamp said flanges together, a nut screwed up on said bolt, and means for locking said nut.
