RAIL-JOINT.

i SPECIFICATION forming part of Letters Patent No. 407,302, dated July 16, 1889t Application filed March ll, 1889. Serial No. 302,887. (No model.)

To all whom t may concern.-

Be itknown that I, MILTON C. NILEs, a citizen of the United States, residing in the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Joints, of which the following` is a specification.

This invention relates to improvements in that class of rail-joints in which the grippingforce thereof upon the rail is directly dependent upon and limited by the elasticity or spring of the metallic plates thereof, but is more especially designed as an improvement upon the invention set forth in the application for Letters Patent of the United States, filed by me on or about October 29, A. D. 1888, Serial No. 289,441, and allowed the 27th day of December, A. D. 1888. In that application was shown a clamping-plate piv- 'otedon the rail-tiange so as to engage the base-plate at the outer edge thereof, and firmly clamp it against the under side of the rail, when the inner edge thereof was depressed by means of screw-bolts working through a brace-plate confined between the top of the rail and the outer edge of the clamping-plate, the power of the grip of all these parts upon the rail being dependent solely upon and limited by the elasticity of the pivoted or lever-clampin g plate.

The prime object of this invention is to dispense with dependence upon the elasticity of any of these parts of the joint, and to provide a perfect rail-j oint by the employment of rigid unyielding parts.-

Another object is to have this rigid joint of such a character that the power of the grip thereof may be readily adjusted, vso that the parts may be further tightened at anytime, and thus compensate for any looseness .due to expansion, contraction, wear of the parts, or any other cause.

A further object is to have the rigid joint of such a character as to brace the top of the rail against thelateral pressure of the flanges of the car-wheel.

Other objects are to tighten the base-plate on each side ot the rail by means of appliances on one side thereof only, and to coinbine with my rail-joint a nut-lock of peculiar and novel form especially adapted for use in connection with this joint.

I attain these objects by the devices illustrated in the accompanying drawings, in which- Figure lrepresents a perspective view of a section of lrail, showing a joint applied thereto, embodying my invention; Fig. 2, a detail perspective view of the brace-plate; Fig. 3, a similar view of the lever-clamping plate; Fig. 4, a similar view of the base-plate; Fig. 5, a transverse section through the rail, showing the joint in end elevation; Fig. 6, a transverse section through the rail and joint, showing the tightening-bolt in elevation; Fig. 7, a similar view to Fig. 6, showing a modification of my invention, in which the tightening-bolt through the rail is dispensed with; Fig.Y 8, a side elevation of a sectionof .the rail with my joint applied thereto, illustrating the detachment of the nut-lock; Fig. 9, a vertical section on the line9 9 of Fig. 8, and Fig. 10 a perspective view of the nut-lock plate.

Similar letters of reference indica-te the same parts in the several figures of the drawings.

Referring. by letter to the accompanying drawings, A B indicate the meeting ends of the rails, and C a base-plate underlying the ends of the rails an d extending practically an equal distance on cach side of the meeting ends of the rails, consisting, preferably, of a iiat plate of slightly greater width than the iiange D of the rail, and having the side edges thereof upturned, so as to form overhanging or hook shoulders E and E', against one of which the rail-flange in operation is designed to abut.

Vith the overhanging shoulder E at the opposite side of the base-plate is designed to engage the outwardly-turned lower edge F of' a lever-clamping plate G, pivoted at Il upon the rail-flange, and provided about the center of height thereof with a notch or ledge I, upon which rests the lower edge of the braceplate J, the upper edge of which bears against the under side of the top K of the rail, between which two parts the said brace-plate is confined.

The brace and clamping plates, taken together, constitute a toggle for clamping or binding all of the plates upon the rail, and the pressure uponthe knee thereof 1s pref- IOO erably obtained through the medium of al headed bolt L, working through the web of the rail and loosely through both of said plates, upon the projecting end of which is secured a nut M, preferably bearing against an extension of the clamping-plate above the knee of the toggle to constitute a better bearing for the nut, and thus enabling the employinentof a ti ghtenin g-boltworkin g through the rail at an angle, instead of parallel with the line of movement of the knee of the toggle, for in practice it is intended that the clainpingplate when in its operative position, and the parts clamped sufficiently tight for practical purposes, shall stand in substantially a vertical position, and therefore at right angles to the tightening-bolt, but not necessarily.

It will thus be readily understood that when the several plates are put together, as j ust de* scribed, and the tightening-bolt is operated, the first effect will be to draw the base-plate late `ally toward the clanipingplate until the shoulder E thereof abuts against the edge of the rail-flange, after which the gripping force will be equalized between the flange and top of the rail, the former being tightly gripped by the lever-clam ping plate at the pivotingpoint thereof, while the latter will be directly braced against and so as to effectually resist the lateral pressure of the flange of the earwlieel by the brace-plate, and it is equally obvious that the power of the grip of this joint is practically unlimited, does not de pend upon the elasticity of the plates eomposing it, and is also readily adjustable, and may be varied at will simply by tightening or loosening the nut applying' the power to the knee of the toggle.

lVhile I have described and shown several plates of the joint as detachably connected together and simply engaging one another at their meeting edges, it would be no departure from the spirit of my invention to unite these plates with each other bya hinge, knuckle, or knee-joint, such as is well known in the arts; nor do I desire to limit myself to the partieiilar manner herein described for applying power to the kiiee-joint of the toggle through the medium of the bolt passing through the web of the rail, for, as illustrated in Fig. 7 of the drawings, the same results would be accomplished by the employment of the draft plate N, confined between the rail and the brace and clamping-plates, with the edges bearing thereon at the point of conjunction of said joints with the rail, through which plate the headed tightening-bolt could work and furnish sufficient resistance and bearing for the operation of the toggle. In fact, the

broad idea of my invention is a toggle comprising a brace and clamping plate, by means of which the joint is attached to and secured upon the rail, and, so far as relates to this feature of inyinven tion, it is immaterial how the power is applied for operating the toggle, and whether the toggle works toward or away from the rail, so long as it accomplishes lthe desired object, that of tightening, binding, and securing the joint to the rail. t

It is also within my invention to combine with this particular form of rail-joint a nntlock especially adapted for use in connection therewith, and which can not well be employed in connection with any other railjoint or fishplate heretofore invented, so far I am aware, at least not in its present form, for this nutlock depends upon the peculiar forni of this railj oint for its effectiven in operation, and is readily atached thereto and detached therefrom without in any wise affecting the joint. To this end I employ a lock-plate O, (more clearly illustrated in Figs. S, E), and lO of the drawings,) of a length substantially equal to the distance between the nuts on the tightening plates, provided with a rearwardly downwardly turning lip or flange P along the upper edge thereof, designed to hook over and rest upon the extension of the clamping-plate above the tightening-bolts, while from the lower edge thereof at the ends projects a pair of ears Q, at a right angle from the :face o f the plate when the latter is inserted in position between the nuts, but are designed to be bent down, so as to lie parallel therewith and under t-he nuts, and thus prevent the accidental lifting and unseating of the lock-plate,

and at the same time prevent the rotation of the nuts upon the bolts. The lip I serves to prevent the removal of the plate horizontally and the ears Q vertically, thus eifeetually securing the lock-plate tothe joint, and at the same time preventing the rotation of the nut upon the bolts due to the jarring of the passing trains; but this lock-plate may be readily detached at any time by bending up the ears thereof, when the nuts of the joint may be tightened or the joint removed from the rail.

As before stated, a'nut-lock of this peculiar character is especially adapted for use in con neetion with my rail-joint, for in the form shown inthe drawings it could not well be employed in connection with any other form of rail-joint heretofore invented, so far as I am aware, and for that reason I desire to clai in the same herein in combination with my railjoint.

I'Iaving described my invention, what I claim, and desire to secure by Letters Patent, is-
