(Cl. With-163) 15 Claims.

The present invention relates to derails and particularly to derail guide boxes and has for its primary object the provision of a new and improved derail and derail guide box which may be constructed readily and economically.

Another object of the present invention is the provision of a new and improved derail guide box which is adaptable exactly to fit any height of rail without requiring adzing of the ties under the rail or guide box or shimming at these points.

Another object of the present invention is the provision of a new and improved derail guide box which is adaptable to any system of track construction, i. e., systems in which the rails are supported either level or canted.

A further object of the present invention is the provision of a new and improved derail guide box which may be readily constructed to be of a desired width, whereby it may be readily and accurately installed no matter what the distance between ties.

Another object of the present invention is the provision of a new and improved derail which will fit any kind of track construction and which may be installed with the assurance that it will fit accurately.

Another object of the present invention is the provision of a new and improved sliding derail adaptable to rails supported on level or canted tie plates and wherein the movement of the derail block on and off the rail has the same relation to the rail as though both the rail and derail guide box were flat upon the ties.

A further object of the present invention is the provision of a new and improved derai guide box which may be fabricated readily from a number of parts which can be out, forged and welded to form the box or in which the parts may v fit tie highest rail of a series rails without change and which can be made to fit lower rails by trimming oiT portions of the front brace and (preferably) side plates, whereby the derail guide box may then be supported upon the ties by horizontal tie flanges secured to the side plates at the proper heights.

Another object of the present invention is the provision of a new and improved guide box having horizontal tie flanges for securin the box to the ties, which tie flanges extend underneath and beyond the rail to provide a unitary guide box tie flange and tie plates, the tie flange also being provided with braces for engaging the far side of the rail and being apertured to receive securing spikes bearing thereagainst, thereby to provide a secure installation.

The derail of the present invention is so constructed that it may be adapted for various sizes of rails and for various types of syst s, such, for instance, as those wherein the rat. is level or canted. It may be constructed readily, as by fabrication, from a, number of component parts which are or forged or from a number of parts which are cast into the requisite shapes. It comprises but :a relatively few parts, may

3 be noted from the following description and from the drawings to which reference is now had.

The derail, which is indicated as a whole by reference character it, is illustrated as being o the sliding but it should be understood at certain features of the invention may utl zed in the construction of other types of derails, for instance, as hinged derails.

The sliding derail illustrated in the includes two main portions. These rail block E2 and a derail guide box, indicated as a whole by the reference character hi, upon which the block is slidably mounted. It is to the guide box that the present invention particularly pertains and it is, therefore, contern' ated that any desirable or suitable form of derail block. may be used.

fhe illustated derail block 32 includes a su porting or body section it (see Fig. i) extending to one side from the derailing portion. it is supported on the guide box for what may be termed an up and over movement, movable from a retracted position in illustrated in e to the which it is illulstrated in Figs. 1 u. ably supported in hearings to be e in greater detail hereinafter by a rearwardly extending generally hook shaped portion (see Fig. 2), a pair of intermediate laterall ex tending bearing members 29 a d and a pair of forward main bearings 2 0113 one of which illustrated in the drawings (see 3 and The derail block is also provided with a plurality of downwardly extending lugs 2% near the rear so that suitable operating mechanism may attached to the derail block to move it. Inasmuch as the operating mechanisms may take various forms, these have not been shown.

The derail g ide box includes a pair of vertical side plates 3b and 32, the former being at the left (Fig. 2) and being iden cal to the one at the right except for the provision of a notch 3d at its upper surface, for a reason to be i ereinafter mentioned. The of the vertical side plates may be noted best from 3, 4 and 5, particularly the latter. The main portions thereof are generally rectangular but the ends adjacent the rail extend generally down wardly and away from the rail. e er 'eusions include a portion of inclination and portion 38 extending ne' 1 vertically.

The derail block support...ig and guiding structures are secured to the inner sides of the side plates. These structures are identical, except for one exception, s-- that only one Ll b reference characters. Referring now ticularly to Fig. 5, it be seen structures include a generally holding-down shelf secured of the central portion of the surf configuration of ports and of end of the side plate.

The left holding-down shelf as indicated by reference characte region of the notch 3 8, for the rece ing means for the derail block. means may be a padlock (not shown).

The derail block is supported and guided ii part by the three pairs of structu elements just referred to. The holding down slves itcooperate with bearings 2i; and 2 to revent undesired vertical movement of trieder :1

as it is slid between its two positions; the seats 52 are engaged by the bearing members 2% on the underside of the derail block whereby the derail block is moved vertically it moves from one position to another; and the pads i iserve to assist in preventing undesired lateral movement of the derail block. fhe two positions of the derail block are illustrated in Figs. 3 and 4:. In Fig. 3 the derail. block is shown in derailing posi tion on top of the rail. At this time the bearing members are at the front sides of the seats d2 while bearings 22 are disposed substantially immediately below the forward ends of the holding-down shelves lil. In the retracted position illustrated in Fig. 4, the bearing members 2:; abut against the rear side of the seats and the bearing members 22 are below the rear of the holding-down shelves 49. The front end of the derail block is at this time supported by the apices of the seats 62.

The derail guide box comprises a standard shell adaptable to different sizes of rails. It is designed to fit the highest rail of a series of rails without change and may be adapted to fit lower rails by trimming portions of the plates to and 32 and a front brace 56 shaped with a reversed curve and abutting against the front edges of the side plates. Considered in another manner, the front ends of the side plates and the front brace may be considered as being in clined generally downwardly and away from the web of the rai1the construction constituting a sort of a nose fitting underneath the rail head and adjacent the rail web. It is preferred also that the width of the front cross brace be somewhat greater than the distance between the side plates in order that it may be secured, as by welding, to a pair of generally horizontally disposed tie flanges Eli and 52 which are adapted to be secured, as by welding, to the outer sides of the side plates. More will be said shortly about tie flanges and the way in which they are secured to the side plates.

The derail as a whole is supported upon a pair of spaced apart ties Ed by the tie flanges SE; and which are secured to the vertically disposed side plates. The tie flanges are preferably rectangular in shape and are provided with apertures for the reception of spikes 58, by means of which the structure is secured to the ties. The tie flanges have widths preferably corresponding the projecting portions of the front cross brace so that they may be secured to the brace.

The guide box shell includes also rear cross brace defining structure. This structure includes a curved top brace to, the downwardly projecting ends of which abut against and are scoured to the top edges of the vertical side plates and 32, respectively. The structure includes also vertically dispose-d cross brace 62 of gener' lly trapezoidal shape and secured, as by welding, to the ends of the vertical side plates as and and the cross brace 86.

The vertical rear cross brace 62 is provided with a hearing so adapted to cooperate with the derail blocl: bearing id. The bearing 64%, which is illustrated in Fig. 2, is produced by cutting what may be termed a somewhat L-shaped slot SE in the lower portion of the vertical cross brace.

A l'tlOlfll rigidity is supplied to the derail by middle side braces if; and 2 and rear side braces and it. Th middle side braces are generally trian ular in shape and are secured to the outer and upper sides of the vertical side plates and horizontal tie flanges, respectively. The rear side braces constitute, in effect, extensions of the rear cross brace 62 as they are configured to extend from the underside of the latter to the upper surface of the side plates. The rear side braces are secured to the tie flanges, side plates and rear cross brace.

The derail may be readilyadapted for either level or canted rail systems. In the instant embodiment of the invention the derail is shown in connection with a canted system. The rail, illustrated by reference character til, is supported upon tie plates 82 secured in conventional manner to the ties 54 and supporting the rail 80. The tie plates are notched at their inner and adjacent corners, as indicated by reference characters 84 (see Fig. 1) to provide space for the horizontal tie flanges 58 and 52.

The derail guide box is adaptable exactly to fit any height or rail without requiring adzing of the ties under the rail or guide box or without requiring shimming at the same locations. Furthermore, it is adaptable to systems in which the rails are supported on either level or canted tie plates. The adaptability may be noted from a comparison of the embodiment of the invention to a system wherein the rail is supported upon level tie plates. The guide box is quite similar to the one previously described except that the horizontal tie flanges 5G and 52 (like reference characters being used to indicate like parts) are disposed vertically relative to the side plates and the lower ends of the side plates are not only parallel to the tie flanges but are also perpendicular to the side plates and base, as distinguished from being trimmed ofi" at an angle corresponding to the canting.

The derail guide box illustrated in Fig. 6 is of a full height, i. e., it is dimensioned to fit the largest size rail (39A) of a series of rails with which the guide box is intended to be used. The side plates 30A, the front cross brace 46A, the middle side braces ltA and the rear side braces 53A have their maximum dimensions.

To adapt the guide box for a rail of lesser height '(rail 85B) it is necessary only to trim off portions of the side plates (preferably) and the front cross brace and to use smaller sized middle and rear side braces, as may be noted by comparing the elements 3M3, 56B, Hi3 and MB of Fig. '7 with the corresponding elements shown in Fig. 6, and to secure the tie flanges 5!] and 52 and the braces at the proper positions relative to the side plates.

An adaptation to an even smaller size of rail (860) is illustrated in Fig. 8 and here again the portions of the side plates and front cross brace which are trimmed on are indicated by their respective reference numbers followed by the suffix C.

The derail guide box is also adaptable to different spacing between ties. All that is necessary to adapt it to different spacing is to change the dimensions of the cross brace structure.

Another feature of the present invention is the provision of a derail guide box having unitary tie fianges and tie plates. A guide box of this character is illustrated in Figs. 9 and 10. The guide box structure illustrated in Fig. 9 corresponds to that of the first described embodiment, except for the construction of the unitary tie flanges and tie plates, which are indicated by ref- Gil erence character 98. It may be noted, particu larly from Fig. 9, that the tie flanges are provided with front portions 92 extending underneath and beyond the base of the rail. The rail may be supported either level or canted upon this portion and in the illustrated embodiment it is shown supported in canted position. The canting of the rail is effected by a small pad 94 under neath the outer side of the rail base and having a vertical projection 36 abutting against the rail. base to prevent the rail from moving away from the derail. The extensions of the horizontal tie flanges are apertured, as indicated by reference character 98, through which spikes I extend in abutting relation with the flanges between to hold the derail in place.

It is readily apparent, therefore, that the derail guide box may readily be adapted to fit any kind of track construction and may be installed with the assurance that it will fit accurately. It is apparent also that when the invention is utilized in conjunction with sliding derails, the movement of the derail block on and 01f the rail has the same relation to the rail as though both the rail and derail guide box were flat upon the ties.

The derail guide box of the present invention may be readily fabricated from a numer of parts which can be cut, forged and welded to form the box. This is the construction employed in the embod'ments of the invention described. However, some, or most, of the parts of the guide box may be made as castings and assembled as by welding.

It i contemplated also, to avoid the work required to fabricate the vertical side plates and supporting and guiding structure mounted thereon of steel plate, that these structures may be made of steel castings. Thus the side plates, together with the holding down shelves it, the seats 42, and the pads as, may be made as single steel castings.

It is contemplated also that the derail guide boxes be made from a sub-assembly unit which may be termed standard shell. This shell in cludes the vertical side plates and elements secured thereto and the front and rear cross brace structure. This shell may be fabricated or cast as a unit and dimensioned to fit the highest rail of a series of rails without change. The shell can be made to fit lower rails by trimming off portions of the side plates and front brace, after which the horizontal tie flanges are secured to the side plates at proper heights and desired anglee to adapt the guide box to desired track construction.

Other modifications of the present invention will occur to those skilled in the art, and it should be understood that the specific details of the described embodiments are not intended to be limitative of the invention except in so far as set forth in the accompanying claims.
