description and not of limitation.

This improved rail comprises a base 2 having side flanges 3 for the reception of the usual holding spikes 4 by means of which the base is secured to the cross ties, and a detachable head 5 fitting such base and which head is shown as reversible. In the present improvement the base is lengthwise channeled or recessed, as at 6, to provide a pair of webs 7 having diverging inner side faces 7' forming what may be termed a V or wedge shaped The head of the rail is provided, at the top thereof, with a lengthwise extending channel or recess 8 located midway of its width, thus forming a pair of similar tread surfaces 9 and 9'. This head has a depending web 10 conforming to the channel or recess in the base, and therefore, is of tapered or wedge form, adapted to snugly fit the recess or channel in the base. For detachably connecting the head and base suitable vertically located bolts 11 are pro vided, the heads or nuts of which are located in the channel 8 of the head and preferably 'in suitable recesses 12 thereof. In certain instances these connecting bolts may be first passed through the base, wlth the heads thereof fitting into recesses 13 at the bottom of the base and the nuts thereof in the recesses 12 of the head, or this may be reversed so that the heads of the bolts are located in the recesses 12 of the head, while the nuts are located in the recesses 13 of the base, or if preferred, the base may be provided with nut receiving openings 14 at the bottom of the channel 6, (see Fig. 2), for the reception of nuts prior to the application of the head to the base and then the bolts passed through the head for engagement with the nuts. The recesses at the bottom of the channel 8 have sufficient size to permit the turningof the bolt heads or nuts located therein while the recesses 13 or 14 in the base are of a size to prevent the turning of the nuts or bolts during the tightening of the nuts and in practice, split washers or other means may be used to prevent jarring loose.

In practice the base webs 7 are provided with transverse bolt openings 15 adjacent to the ends of the rail for the reception of fish plate bolts 16, the heads of which are preferably located in registering recesses 16 formed in the opposed webs of the head and base, thus likewise facilitating the tightening of the nuts.

Various forms of 'fish plates 17 may be used. In Fig. 2 the fish plates are flush with the sides of the detachable head. In Fig. 4 the fish plates are located in recesses 18 of the base, whereby the head of the rail may overlap the base and thus provide means for lifting the rail head from the base, which may also be accomplished by providing in the side faces of the rail recesses 19 (see Fig. 5), for the reception of cant-hooks;

In the form shown in Fig. 5, the top edges 20 of the base webs 7 and the overlapping portions 21 of the head are inclined downwardly and outwardly thereby forming a water shed to prevent the passage of water between the head and the base. 7

In the form of rail shown in Fig. 4, the tapered side faces of the web of the head and base terminate in straight faces, as distinguished from the continuous tapered faces shown in Figs. 2 and 5. In practice the rail heads may be assembled with the bases so as to break joint therewith, whereby a pair of heads and a pair of bases may be effectively tied together.

The present improvement not only prolongs the life of this improved railhead to twice its normal life, since it may be readily reversed without'removing the entire rail with its base and not only reduces the cost of replacing it, since a large part of the street does not have to be torn up with .the consequent cost of relaying it, but the improvement is so constructed that the head may be easily and ex editiously removed without the necessity o tearing up any appreciable part of the street surface causing an obstruction to trafiic. Thus aside from the simple and efficient mode of connection, the rail is extremely practical and overcomes the disadvantages heretofore present in the use and of detachable heads for street railroad rails, and has been considered by railroad engineers as solving the problem of providing a readily removable head for railroad rails of this kind and is quite a step in advance over those forms of' railroad rails heretofore patented having a detachable head, which for one reason or another have been considered 'im racticable and which no doubt has prevente the adoption and commercial success thereof.

It is to be understood that by describing in detail herein any particular form, structure or' arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I claim:
