RAIL-JOINT PATTERN.

To this end the invention contemplates a simple and practical construction of rail joint pattern embodying, as a part thereof.

interchangeable means for accurately loeating the spiking slot or spiking lug positions of the pattern to correspond exactly with thespiking points specified in any particular order, thus enabling the manufac turer to use a single pattern which is adapted to accommodate itself to a variety of spacingsor positions of the spiking members. In this connection the invention possesses special utility in its application to the type of pattern employed in the manufacture of step or compromise rail joints. In the manufacture of this type of rail joint.

the joint bars are usually made of steel or malleable iron castings, and of a design and configuration corresponding to that of the rail sections to be united, so that difference in the height and section of the dissimilar rails is compensated for. In addition to the variation in height of section between the dissimilar rails connected by a step-joint bar, there is also a variance in the position and shape of the spiking members. This has ordinarily been provided for by making new and separate patterns to cover the ditferent variations, whereas it is the purpose of the present invention to provide a single rail joint pattern with means whereby there may be associated therewith a number of interchangeable pattern pieces or core prints which not only locate the spiking positions. but also define the character and shape of the spiking member, whether that member simply be in the form of a spiking lug. plate, flange or equivalent projectionthat may or may not be provided with a spike slot or hole. Thus, provision is made for greatly economizing in the manufacture of rail-joint bars by reduclng the number of Specification of Letters riatent. Application filed :June 17, 1911.

patterns required to a minimum, and also provision is made for locating the spiking lugs at various positions along the length of the splice bar in accordance with the requirements of the varied railroad specifications.

The essential feature of the invention involved in the provision of a rail-joint pat tern with adjustable means for locating and defining the spiking positions is necessarily susceptible to a variety of structural moditi cations without departing from the scope of the invention, but a few preferred and practical embodiments of a the latter are shown in the accompanying drawings, in which- Figure 1 is a perspective view of a railjoint pattern constructed in accordance with the present invention, the view illustrating the pattern with one of the detachable pattern pieces or core prints in place. Fig. Bis a detail in perspective of one form of detachable pattern piece that may be applied to the pattern-body. Fig. 3 is a detail sectional view illustrating a practical form of interlocking connection between the detachable pattern piece and the body of the pat tern. Fig. 4. a plan view of a detachable pattern piece. Fig. 5 is a sectional view similar to Fig. 3, showing a modified form of pattern piece or core print wherein a pair of the same provide a spiking slot or hole between them. Fig. 6 is a projected plan view of the modified pattern construction shown in Fig. 5. Fig. 7 and 8 are views similar to Figs. 5 and 6 illustrating another modification wherein a single pattern piece or core print is intended to provide on the casting a spiking lug that is engaged by the head of the spike.

hike references indicate similar parts in all the views of the drawings.

In carrying out the invention no special change is required in the design or use of the ordinary patterns, such as are commonly employed in the process of casting steel or malleable iron rail-joint bars; hence, for illustrative purposes there is shown in the drawings a design of pattern of the kind that is used in making step or compromise rail-joint bars. This pattern comprises a body portion having a bolt plate member 1 for shaping the corresponding member of the bar, an inclining foot-flange member 2 for shaping the corresponding part of the joint bar, and a base member 8, integral with the foot-flange member (or otherwise rigidly united thereto) for shaping the railsupporting base-section of the bar. To provide for adapting the present invention to the main pattern it is proposed to associate therewith a number of interchangeable pattern pieces or core prints to locate any prescribed spiking positions and to define the character and shape of the spiking member. All of the various pattern pieces are adapted to be detachably fitted to the pattern body so that, through the interchangeability thereof, a great variety of variations in spiking positions and in the shape of the spiking members may be provided for with the same pattern. To illustrate, there is shown ill-Fig. l of the drawings a pattern body which provided at or near the ends thereof, and in its edge portion, with dovetailed or equivalent seats t, formed by grooving, slotting, or otherwise, and adapt ed to have detachably interlocked therein a dove-tailed holding rib 5 of a pattern piece 6 that may be held fast, though detachably, in its adjusted position, by any suitable fastening means, such, for instance, as a removable retaining plate 7, as suggested in Fig. 1. Also any excess in length of the seat a over the length of the holding-rib 5 may be taken care of by a suitable detachable filler-piece 8, such as is also suggested in the illustration of Fig. 1.

The pattern piece 6 may be of any prescribed form. It may be of the lug type, as shown in Figs. 1, 2, 3 and 4:, and having therein a core slot 9 to define the spike-hole or spikeslot in the finished casting. It will thus be seen that the detachable pattern piece 6 is essentially a core print, and to illustrate the different forms that it may assume it will be seen in Figs. 5 and 6 that a pair of pattern pieces or prints 6 may be employed in spaced relation, and provide a pattern which disposes the core-slot or hole 10 for body of the oint bar, as is evident from an inspection of Figs. 5 and 6 and, again, a single pattern piece or core print 6 may be employed under conditions Where it is intended to simply provide a spiking lug on the bar that is engaged by the head of the spike, as may be seen from an inspection of Figs. 7 and 8 of the drawings.

From the foregoing it will be apparent that a wide range of structural modification may be resorted to in the character of the detachable pat-tern pieces employed, and also in the manner of adjustably securing them in place, without departing from the scope of the invention, so it is believed the few illustrations given will fully exemplify the latter.

I claim 1. A rail joint pattern consisting of a pattern body of angle form provided at its outer edge with a plurality of seats, sepa rate projecting spiking-member patternp eces extending outwardly from the pattern body and having an ad ustable engagement with said seats, and means for retaining the pattern-pieces in their adjusted positions on the pattern body.

2. A rail joint pattern consisting of a pat? tern body of angle form provided in its outer edge with a plurality of open dovetailed seats, and separate projecting spiking-member pattern-pieces extending .outwardly from the pattern body and having at their inner edges dove-tailed ribs which adjustably fit and interlock with the said seats,

each of said pattern pieces comprising means for locating and defining in the mold a spiking member for the casting, and retaining means for securing the pattern pieces in their adjusted positions on the pat tern body.

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