HENRY OSHEA, OF J OHNSTOIVN, PENNSYLVANIA, ASSIGNOR TO THE JOHNSON COMPANY, OF SAME PLACE.
PATTERN FOR RAI LWAY-SWITCH WORK.
SPECIFICATION forming part of Letters Patent No. 533,735, dated February Application filed March 23, 1894. Serial No. 5041397- (N 0 model-r To (055 whom it rmty concern:
Be it known thatLIIENRY OSHEA,0E Johnstown, county of Gambria, State of Pennsyl- Vania, have invented a new and useful Improvement in Patterns for Railway-Switch Work, of which the following specification is a true and exact description, due reference being had to the accompanying drawings.
My invention relates to an improvement in patterns usedin the manufacture of switch work for railroad tracks, and has for its object to provide a pattern adjustable in a manner hereinafter described, whereby one pattern may be adapted to varying structures.
By switch work I mean the several structures in railway tracks such as frogs, crossings, mates and switches. Heret-ofore in the manufacture of this work, if of cast metal, it has been customary to make a new pattern for nearly every ditterent switch piece owing to the varying angles and curves required. This soon causes an accumulation of practically useless patterns, and, as each one is different, the cost of making them is a large item. By my invention I am enabled to adapt the same pattern to different crosses, mates or whatever it may be for.
In the drawings, Figure 1 represents a mate and Fig. 2, a frog embodying my invention. Fig. 3 is a section on line X-X of Fig. 2, and Fig. 4. is an end view of Fig. 2 from line Y-Y.
In general my invention consists in a central body, or box portion adapted to be used for different angles, and having upon its top a removable board having the desired track surfaces formed thereupon.
In the drawings A is the body or box portion. This is essentially nothing but the vertical walls, with neither top nor bottom. The ends of this are arcs of circles swept from a center approximately where the gage lines of the two tracks cross, for a purpose later explained, and the center is preferably narrowed in as shown, thereby reducing the weight of the casting, though the two sides may be straight. On top of the box A is secured the board or plate F having the desired track surfaces formed thereupon, and to the ends are screwed the rail patterns B in alignment with the track surfaces of plate F. It
is evident that the widest angle any given box is capable of being adapted to is that which places the outside edge of the rails B on the outside of box A, and the narrowest angle is that which brings the two rail patterns to 5 gether. It will also be seen that the length of the plate F limits the width of angle admissible, the shorter the plate the wider the angle.
In order to be able to furnish a pattern any desired angle I have on hand a set of boxes, the widest angle of one corresponding to the narrowest of the next, and I have in stock blank plates F, that is, plates which are fitted to the various boxes, but have no track surfaces formed thereupon. I also have a sufficient number of the short rail patterns B of various sections. IVhen I desire to prepare a pattern for any special structure I select the box best suited to it and fasten a suitable plate in place. On this blank plate I shape the desired track surface by any suitable means. A shaping machine having cutters or knives of the proper configuration is a very good way of doing it. I next fasten to the ends of the plate, and in alignment with the track surfaces thereon, the short rail patterns B by any means as by the screws S. The lower flanges of the rail are shown loose at the joint J and held in position by dowels d. This is to permit the pattern being removed from the sand of the mold. Thus it will be seen that the only thing I replace is the plate F, and this may be cheaply prepared and kept in stock. In this manner I am enabled to cheaply and quickly adjust a pattern to the desired position and thus save a large portion of the expense of a new pattern.
The body and the rail patterns may be of metal and more durable than of wood.
I am aware of an application filed by AJ. Moxham on March 23, 1894, and bearing Serial No. 50%,894, and such inventions as are therein claimed I do not claim, but,
Having thus described my invention, what I claim, and desire to protect by Letters Patout, is- V l. A pattern for railway switch work, said pattern comprising a central body portion with curved ends, and removable rail patterns secured at the endsthereof, and a removable I00 top on said body, said top having grooves formed therein, said grooves being in alignment with the gage line of the rail patterns.
2. A pattern for railway switch work, com- 5 prisinga body composed of vertical sides, and
having curved ends a top plate removably secured thereon, said top plate having track grooves formed thereon, anddetachable rail patterns secured at the ends of said top plate :0 and having their gage lines in alignment with the grooves in said top plate whereby said body portion and rail patterns may be repeatedly used in conjunction with top plates having various track surfaces thereupon.
In testimony whereof I have affixed my sig- :5 nature in presence of two witnesses.
