SPECIFICATION forming part of Letters Patent No. 601,220, dated March 22, 1898;

Application fina June 18,1897. seriaiNo. 641,320. (No model.)

To all whom it may concern: Each of these sections has a wedge-shaped o Be it known that I, GEORGE W. BENNUM, groove B formed lengthwise thereof and a citizen of the United States, residing at adapted to receive one side of the flange C of Georgetown, in the county of Sussex and State the rails, as clearly shown in Fig. 2, and said 5 of Delaware, have invented a certain new and grooves are preferably somewhat deeper than useful Improvement in Railway-Joints, of said flanges in order that the latter may not which the following is.a specification. reach the bottom thereof, and consequently My invention relates to a new and useful permit the increased hold upon the rail when improvement in railway-joints, and has for drawn tightly against the same'. A series of ro its object to provide a simple and effective holes D (here shown as four in number, but

25 With these several ends in view this inven- While I have here shown the bolts as held tion consists in the details of construction lin place by the wedge-shaped keys, it is oband combination of elementshereinafter set vious that the same result may be had by nuts forth, and then specifically designated by the run upon said bolts, the latter being threaded claims. for the reception of such nuts; but on account 3o In order that those skilled in the art to of the impossibility of the wedge-shaped split which this invention appertains may underkeys being jarred from either position by the 8o stand how to make and use the same, the convibrations of the track they have been found struction and operation will now be described to be very serviceable for this purpose.

in detail, referring to the accompanying draw- Since there is often a tendency for the rails 35 ings, forming a part of this specification, in of a track to crawl either byv expansion', or rewhichtraction or from the fact that the track is Figure l is a side elevation 'of the meeting placed upon a grade,Ihave provided against ends of two rails, showing my improved jointthis independent movement ofl the rails by block applied thereto; Fig. 2, a section at the forming notches I in the sections of the block,

From the foregoing'description it will be seen that when the meeting ends of two rails are clamped by a block made in accordance with my improvement the bolts passing through the sections of said block below the ilanges of the rails tend to draw the blocks inward at their lower ends, thereby causing a gripping or pinching action upon the [langes of the rails, which so increases the hold of the block upon said rails as to preclude the possibility of the latter working loose. Another feature of this arrangement is that the bite of the sections of the block upon the flanges of the rails is increased in proportion to the strain upon the bolts, as a certain amount of leverage is provided in favor of the bolts, so that a tendency to separate the sections of the block from the flanges of the rails does not bring an undue strain upon the bolts.

In practice a joint made by my improved block will not only serve to hold the rails in perfect alinement, which is necessary for the proper construction of a railway, but will also give to the rails a certain amount of support on account of the length of the block and the fact that it grips the rails throughout its length and thus forms practically a continuous rail, since the block is of greater strength than the rails. This fact permits the joint to be placed between two cross-ties, or, when desired, it may be placed directly upon a tie by properly cutting away the latter. The sections of the blocks are here shown as being concaved lengthwise, as indicated at K, the object of which is to lighten the blocks, while at the same time permitting the setting in of ballast, so as to assist in preventing a sidewise movement of the track when used between two cross-ties.

Among the advantages of my improvement is the fact that holes do not have to be formed in a web of the rails for the passage of the joint-bolts, since these bolts pass beneath the rails, thus avoiding the labor and expense of forming such holes, and one of the advantages of this is that short or broken rails may be inserted within a line of track without having to transport the saine to a locality where the drilling may be accomplished by machinery or the tedious operations performed of drilling the bolt-holes by hand. For this kind of work when an entire track is fitted with my improved joint-block the drilling of holes for the passing of the pins .I may be dispensed with, since the remainder of the track will serve to prevent any undue crawling of the short sections of rails which may be inserted thercin,and when this method is followed the insertion of a short length of rails or the mending of a broken rail will be exceedinglysiniple and quicklyaccomplished, as it will then only be necessary to cut the rail to the proper length, place it in position, clamp the section of the bleek thereon, and spike it to the tie.

eo1,22o

In the manufacturing of joints made in accordance with my improvement considerable ad vantage is had from the fact that they may be rolled on account of the peculiar shape of each section, thus greatly reducing their cost, while at the same time providing a superior block.

I do not wish to be limited to the exact details of construction of the shape of the sections of the joint-block, as these are minor details which may bc altered to suit the requirements of fancy or the particular work of persons using the blocks.

Having thus fully described this invention, what is claimed as new and useful is* l. The herein-described combination, comprisin the rails the pins adapted to be passed through the flange of the rail, and the jointblock, consisting of two sections each having a longitudinal wedge shaped groove with notches for the reception of the pins and means for causing the sections to clamp the meeting ends of the rails, as and for the purpose described. u 2. As a new article of manufacture the joint-block consisting of two sections each having a wedge-shaped groove for the reception of the side ilange of a rail, and notches formed in the walls of the groove for the reception of pins passed through the flange of the rail, as and for the purpose described.

3. The herein-described combination of the meeting ends of two rails, the block A composed of two sections which are counterparts of each other, said sections having bolt-holes formed therethrough and notches formed therein, pins projecting downward from the rails for fitting said notches, bolts passed through the holes, washers fitted over the ends of the bolts, and split keys passed through slots in the bolts and driven against the washers, as specified.

yl. rlhe herein-described combination of a joint-block consisting of two sections, each section having a longitudinal wedge-shaped groove I3, holes therethrough for the passage of bolts, notches formed therein for the reception of pins, and concaved at its lower portion, substantially as and for the purpose set forth.

5. In combination,the rails,the joint-blocks consisting of two sections, each having a wedge-shaped groove for the reception of the side flange of the rails, and notches in the walls of the groove, pins adapted to be passed through the v[lange of the rails in to the notches, as and for the purpose described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
