Specification of Letters Patent.

Patented Aug. 15, 1905.

To all whom it may concern.-

Be it known that I, FREDERICK HAGI-IMANN, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful improvements in Rail-Joints, of which the following is a specification.

My invention relates to improvements in rail-joints, and has for its object to provide a joint which can be easily adjusted and will be securely and permanently held in place and wherein the bolt-nuts will not work loose.

To this end my invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

in the accompanying drawings, forming part of this specilication, Figure 1 is a side view of my improved rail-joint in secured position. Fig. 2 is a cross-section thereof, on an enlarged scale, taken on line m w of Fig. 1. Fig. 3 is a side view of enough of the joint to show a single bolt and elongated bolt-hole; and Fig. i is a horizontal section of the sliding bar alone, taken on line 1 3 of Fig. 3.

in the drawings, A and B represent the two rails to be joined, and 2 and 3 two bars or plates, one fixed and the other sliding, disposed on opposite sides of the rails and overlapping the meeting ends thereof. The fixed bar 2 on one side of the rails is made, preferably, in the shape of an angle-bar of usual construction, so as to fit closely between the head 1 and flange 5 of the rail, and may be made, as shown in the drawings, with an inturned plate 6, forming a supporting-base for the rail and the bottom of the other bar 3. The sliding bar 3 is also preferably in the form of an angle-bar, so as to fit closely between the head and flange of the rail, and is provided with a driving-head 7 at one end and with longitudinally slotted or elongated bolt-holes 8. Above and below the rear ends of the boltholes, being the ends nearest the driving-head, the bar is provided with longitudinally-extending lugs 9, spaced apart just a sufiicient distance to receive between them the nut 10 when the same is turned to bring its sides into substantial parallelism with the lugs.

The bar 3 is so constructed that its outer side or face about the bolt-holes will extend to or beyond the side of the head of the rail, whereby the nut may be easily and freely manipulated.

To give elasticity to the joint and form a 'cushion to take up the thrusts and shocks caused by passing trains, each bar is channeled on the side toward the web 11 of the rail, and a block 12, of wood or other resilient material, is inserted therein, the blocks extending inwardly beyond the bar, so as to en gage the web when the bolts are tightened. The bar 2 and the blocks 12 are apertnred at proper intervals to receive the bolts 13, and

the bottom of the bar and the base-plate 6 are apertured at desired points to receive retainingspikes 14.

Further, to tighten the joint after the nuts 10 have been screwed onto the bolts as far as possible, the sliding bar 3 is formed with slightly inclined outer faces 15 about the slotted bolt-holes, the facessloping or swelling outwardly from the forward to the rear end of each bolt-hole, as shown in Fig. 4.

In use the fixed bar 2 and adjacent wooden block 12 are first put in place with their boltholes registering with the bolt-holes in the web of the rail. The sliding bar 3 is then put in place on the opposite side of the rail with the forward ends of the slotted bolt-holes 8 (the ends away from the lugs 9) in registration with the bolt-holes in the fixed bar. The bolts are inserted through these holes with their threaded ends 16 projecting through the slotted holes 8. The nuts 10 are screwed on as far as they will go and leave their upper and lower sides parallel with the lugs. The sliding bar 3 is then driven lengthwise by blows upon its driving-head far enough to bring the bolts to the rear ends of the slotted holes 8 with their nuts between the lugs 9, the bars being at the same time tightened against the rail by the wedging engagement of the inclined faces 15 with the nuts. The lugs will positively prevent the nuts from working in either direction.

It will be observed that the resilient blocks 12, being partially inclosed or embedded within the channels of the bar, will be protected from exposure to water and cannot spread under the pressure so as to lose their resili ence. The block embedded in the sliding bar 3 may have slotted bolt-holes like the bar itself and be driven with it, or the holes may be round and the bar stationary, as may be desired.

Various modifications may be made in the details of construction without departing from the principle of the invention, the scope of which is defined in the claims.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a rail-joint the combination, with the meeting ends of two rails, of a bar overlapping the meeting ends thereof and formed with longitudinallyslotted bolt-holes, the outer face of the bar about the bolt-holes extending outwardly as far as the side of the head of the rail and being provided with longitudinally-arranged lugs disposed above and below the bolt-holes at one end thereof.

2. In a rail-joint, the combination, with the meeting ends of two rails, of a bar overlapping the meeting ends thereof and fitting closely against the under side of the head of the rail, said bar being formed with bolt-holes, and a resilient block partially embedded in the inner side of the bar and formed with a bolt-hole to register with the bolt-hole in the bar, said block extending beyond the inner face of the bar and abutting against the web of the rail.

3. In a rail-joint the combination, with two rails, of a bar overlapping the meeting ends thereof and provided with a driving-head at one end and with longitudinally-slotted boltholes, for the purpose set forth.

L. In a rail-joint the combination, with two rails, of a longitudinally -slotted bar over:

lapping the meeting ends of the rails, the bar being provided with a driving-head and with lugs disposed above and below the slots at one end thereof, for the purpose set forth.

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

FREDERICK HACHMANN.
