RAILROAD-RAIL JOINT.
SPECIFICATION forming part of Letters Patent N 0. 722,971, dated March 17, 1903.
' Application filed January 9, 1903. Serial No. 138,4;15. (No modelfl To all whom, it may concern:
Be it known that I, HERSOHEL GLovER, a
citizen of the United-States, residing at T0- ledo, in the county of Oallaway and State of Missouri, have invented a new and useful Railroad-Rail Joint, of which the following is a specification;
This invention relates to joints for the ends of railroad-rails; and it has for its object to With these ends in View my invention consists in the improved construction, arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the.clain1.
In the accompanying drawings, Figure l isa perspective view showing the parts or members of my improved rail-joint separated or detached from each other. Fig. 2 is a horizontal sectional view taken on the line 2 2 in Fig. 4. Fig. 3 is a transverse sectional view,
taken on the line 3 3 in Fig. 2. Fig. 415' a transverse sectional view on the line 4 4 in Fig. 2.
Corresponding parts in the several figures are indicated by similar characters of refer-' once.
The device which constitutes my improved rail-joint is composed of two parts or members, which are designated, respectively, 1
and 2, the part 1 being what I prefer to call the inner member, and the part 2 the outer member of the device. Each of the parts or members comprises a vertical flange 3, which constitutes a fish-plate, a bulged body portion 4, which extends over the rail-flange and which is provided at its outer edge with notches 5 to receive the spikes by means of which the device is preferably secured in position, and the base orsupporting portion-6, which extends under the rail-flange, as will be clearly seen in Figs. 3 and 4 of the drawings. It is obvious that the members 1 and 2 are constructed in conformity with the shape of the rail 7, in connection with which they are to be used, so that the web or flange of said rail shall be firmly held between the side members 1 and 2, the flanges of which constituting the fish-plates will closely hug the under sides of the heads of the rails which are to be joined together by the device.
The base or supporting portions 6 of the members 2 meet and engage each other centrally below the rail-flange and are provided with shoulders or recesses 8 and 9, whereby flanges 10 and 11 are formed, the flange 10 of the inner member 1 overhanging the flange 11 ofthe outer member 2. The reason for this specificconstruction will be presently referred to.
Each of the members 1 and 2 is provided with a centrally-disposed enlargement 12, said enlargements combining to form an abutment for the meeting ends of the rails that are to be joined together by the device, the shape of said abutment being practically that of a centrally and vertically divided short rail end. The enlargements 12 are obviously integral with the members 1 and 2 of my improved rail-joint.
The vertical flanges forming the fish-plates of the members 1 and 2 of the device are provided at their opposite ends with openings for the reception of'the bolts by means of which the device is connected with the ends of the rails that are to be joined together. These openings at one end of each fish-plate are ordinary bolt-holes 13, which are merely sufficiently large to admit a bolt of the desired diameter. The bolt-openings at the 0pposite end of each fish-plate are in the form of elongated slots 14, which will permit of a longitudinal play or' movement of the bolts inserted therethrough. It will be seen that the openings 13 of one member are disposed opposite to the slots 14 of the other member. The meeting ends ofthe rails are provided with bolt-holes 15, which when the ends of w the rails are in close contact withthe enlargements 12, forming the central abutment, shall at the same time aline with the bolt-holes 12 of one of the adjacent members of my improved rail-joint. It will'thus be seen'that when the connecting-bolts 16 are placed in position the said bolts will connect each rail endrigidly and immovably with one of the IOC adjacent members of the device, while the connection with the other member, through the slots 14 of which connecting-bolts extend, will admit of a longitudinal sliding movement which will be amply sufficient to compensate for expansion and contraction, While at the same time the rails are connected with the connecting device and through it with each other with a great degree of rigidity which precludes the possibility of the rails ever getting out of joint or out of alinement with each other. Accidents from sprung and dislocated rails will thus be practically avoided by the use of my improved device.
When my improved railroad-rail joint is in position for operation and rolling-stock passes over the line, it is obvious that the tread of the wheels will exercise its strongest pressure in an outward direction upon the inner member 1 of the joint wherever the joint is encountered. It is when this takes place that the flange 10 of the inner member 1, which overhangs the flange 11 of the outer member 2, by the downward and outward pressure exercised thereon causes the rail ends to be gripped and clamped with increased force and tenacity, thus joining and uniting them together in the most efficient manner at the mostcritical moment.
It is obvious that the enlargements 12 onv the members of my improved rail-joint being firmly connected with the respective rail ends will form a smooth and unbroken surface upon which the wheels of the rolling-stock are transferred from one rail to the other, thus avoiding the un pleasant and detrimental jolting which is apt to occur when rail-joints of ordinary construction are employed. It will also be seen that this practically unbroken surface will exist at all stages of expansion and contraction of the rails. The
condition known in railroad parlance as low joints is thus rendered absolutely impossible by the employment of my invention.
I am aware that certain features of my in vention have been heretofore known and successfully used; but I am not aware that the valuable features of my invention have heretofore been combined in the manner set forth in the foregoing description and illustrated in the drawings. Thus, for instance, fishplates have been used provided with circular openings or bolt-holes at one end and with slots at the opposite end to admit of longitudinal movement, such fish-plates constituting a joint, being each connected in this manner firmly with one of the rail ends to be united. I am not aware, however, that such fish-plates have been provided with body portions extending over the rail-flanges and with seat portions or bases extending under said flanges, thus supporting the sliding movement, which, however limited, would be liable to bring the rail 'ends out of alinement. Again, I am aware that rail-joints have been constructed with seat portions extending under the rail-flange; but I am not aware that such devices, when formed with centrally-disposed engaging flanges have also been provided with the enlargements forming abutments for the meeting ends of the rails, whereby the construction alluded to is rendered especially efficient. I desire it to be understood, therefore, that I do not claim, independently, such features as are already well known in the art. On the other hand, I do not limit myself to the precise construction herein shown and described, but reserve the right to any changes and modifications which'may be resorted to without departing from the spirit and scope of my invention or detracting from the utility of the same.
Having thus described my invention, I claim- A railroad-rail joint comprising parts or members consisting of bulging body portions having upwardly-extending flanges forming fish-plates, inwardly-extending flanges forming seats and centrally-disposed enlargements forming abutments for the meeting ends of the rails, said fish-plates being provided at opposite ends with circular boltholes and with elongated slots, and said baseflanges being provided at their meeting edges with flanges, the flange of the inner member overhanging that of the outer member, in combination with rail ends having circular boltholes which, when saidrail ends are seated upon the base-flanges of the members, in contact with the enlargements forming the abutments, will register with the circular bolt-holes of the fish-plates, and suitable connecting-bolts.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
- HERSOHEL GLOVER.
