JAMES S. PERRY, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO ALBERT M. GATES, OF SAME PLACE.

RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Patent No. 630,518, dated August 8, 1899.

Application neairt s, 1899. Serial No. 717,102. on modeLl To all whom it may concern.-

Be it known that I, JAMES S. PERRY, a citizen of the United States, residing at the city.

of Kalamazoo, in the county of Kalamazoo and State of Michigan, have inventedcertain new and usefulImprovements in Railway- The objects of my invention are to provide.

a new and improved switch for railways in which the improved construction ofswinging rail is substituted for the usual frog, and,

further, to provide an improved swinging rail.

and a strong, simple, cheap, and efiicient device for securing the same. 1

Further objects will appear in the detailed description.

I accomplish the objects of my invention by the devices and means set forth in this specification.

The invention is fully pointed out and defined in the claims.

The structure embodying my invention is fully illustrated in the accompanying drawings, forming a part of this'specification, in which- Figure 1 is a detail plan View of the switch. Fig. 2 is a detail perspective view of the swinging rail and its connections. Fig. 3 is a transverse horizontal detail s'ectionalview through the turn-table or pivot on which the rail swings, taken on a line corresponding to line 3 3 of Fig. 4. Fig 4 is adetail transverse sectional view through theturn-table and rail and adjacent parts, taken on a line corresponding to line 4 4 of Fig. 3. Fig. 5-is an enlarged detail perspective view of the stop for locating the swinging rail positively in position.

In the drawings all of the section views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A A are the main rails of a railroad-track. A A are the rails of a side track or switch, all of which are represented secured to the usual ties.

The style of switch hereillustrated is what isknown as a fly-rail switch, and as my invention does not pertain to this part of the switch, the same being adapted to any style of switch in which a frog has heretofore been used, I will not specifically describe the same, as I do not care to base claim on that specific part. I will only remark that the fly-rails are held together by the usual cross-coupling M, connected by a linkK to an arm K on the rock-shaft G, which is actuated from the switch-stand by proper connections.

I 'I provide in the place of the lusual frog a swinging rail B. The ties L L L are especially equippedto receive, support, and guide the swinging rail. On the ties L L are placed plates F F, respectively,which serve as chairs for the ends of the approaching rails. The rails are notched and spiked to .prevent' their creeping upon the ties and chairs. To the inside of the rails A A, resting on the chair F, are secured stops E, the same being projections from part E, similar to fish-plates, which are bolted to the ends of the rails and form stops against which the web at the end of the rail- B strikes in swinging from side to side. The rails on the plate or chair F are provided with similar stops located on the outside of the rails, which positively locate the swinging rails in the same way in this position. The stop is only ofsufficient size to strike against the web, of the rail, so that the base of the rail can swing under the same and at this point, and suitable blocks are put under the outside rails. My improved turntable is at the center, and to it is secured the swinging rail. The turn-table consists of a base-plate D, having a circular head D, connected thereto bya circular neck D,the crosssection of which clearly appears in Fig. 4. This constitutes the pivot of the turn-table on which the rail swings. Embracing this, preferablyconstructed in two pieces,is the swinging part of the table. This consists of two equal symmetrical halves 0, within each of which is formed one-half of a bearing, like a journalbearing, to receive the head D and neck D, and the parts extend down to and into contact with the baseD below, which thus forms a broad powerful support for the swinging rail. The upper portions of the members are formed like two oppositely-facing fish-plates. Through these fish-plates and swinging rail 13 at this point are bolts a, which secure the same firmly in position. llolts (t are through suitably-projecting cars at the ends of the members C C to retain the same securely in position on the pivot-head D. From this it will be observed that my improved turn-table is very strong, all of the bearing parts are protected from exposure to the elements, and that they cannot be easily obstructed, the table easily brushing to one side any snow or ice or other accumulations on the base-plate D. It is also a structure that can be very easily repaired or installed in position, as all that is necessary is to secure the proper elevation and spike the bottom plate D in position. By the structurealso a perfectly-continuous rail is secured, which is of very great advantage, as it increases the durability of the switch and at the same time avoids any very serious wear on any rolling-stockpassing over it. I provide a connection from this swinging rail to the switch-stand which operates the switch-rails, so that both are operated at the same time. This is accomplished by providing a switch-stand II, having a connecting-rod I therefrom to a suitable eye I, which is bolted to one side of the rail, as clearly appears in Figs. 1 and 2. To this same red I connect the link J, which connects to an arm J on the rock-shaft G, which extends along the track and is connected in any suitable way to the switch-rails to move them in unison with the swinging rail. Thus the swinging rail (in the place of the frog) and the motion of the switch-rails at the ends are controlled by the same means eitectively and practically. I desire to state in this connection that other arrangements of switchstand might be employed in this connection, and while I have shown guard-rails in the usual position occupied in connection with frogs they are not in this connection a necessity, but are merely put in as a means of greater safety,like the guard-rails at a bridge.

It will be observed that by this arrangement of the swinging rail the same is made very short, thus securing great strength, and it will also be observed that the structure can -makes it very desirable and of great advantage over anything known to me.

I am aware that the details of this structure can be considerably varied and that additional locking means to those I have shown can be provided for the swinging rail, though I do not choose to illustrate them in this connection, as my invention pertains principally to the method of securing and locking aswinging rail in a switch.

The turn-table as I show it is the preferred construction, though I will state that other means of securing the rail might be adopted and the turntable be divided into a greater number of parts than I show. The exact structure with few parts is best.

Having thus described my invention, wha't Iclaim as new, and desire to secure by Letters Patent, is-

1. In a railway-switch, the combination of the switch-rails and the rails of the main track; a switclrstand; connection therefrom to the shifting rails; a swinging rail occupying the position of the usual frog connected to the switch-stand and adapted to be swung from side to side; a turn-table to carry the swinging rail consisting of a bottom plate D having the circular head and neck D and D;
