Specification of Letters Patent.

Patented Got. 23, 1917.

Application filed October 9, 1916. Serial No. 124,529.

To all whom it may concern:

Be it known that I, JOHN F. Fosinn, a citizen of the United States, residing at Garbers, in the county of Washington, State of'Tennessee, have invented a new and use ful Railway-Switch; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved railway switch, and one of the objects of the invention is to provide a positive switch mechanism and one in which the derailment of the car wheels is avoided.

A further object of the invention is to provide a railway switch, the connections between the switch points of which and the operating means being below the railway tie, thereby avoiding any obstructions between the switch points, which may come in contact with any structure suspending from the bottom of the car.

A further object of the invention is to provide a switch having improved features of construction. 4

One of the features of construction is the provision of a connecting rod between the two switch points, and to which the crank rod is connected for throwing the switch points, in combination with a second rod connected to one of the switch points, and spring tensioned, and mounted in a guide below the upper faces of the ties, so as to throw the switch points automatically in one direction, incident to the flanges of the car wheels pushing upon the switch points.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a plan view of the switch mechanism, constructed in accordance with the invention.

Fig. 2 is a sectional view on line 2-2 of Fig, 1.

Fig. 3 is a sectional view on line 3-3 of Fig 1.

ig. 4 is a sectional view through a plate, which is designed to be connected with two adjacent ties, and connected integrally to a. cylinder, which supports therein a spring tensioned piston and rod.

Fig. 5 is a detail view of a plate, which integrally carries a cylinder head for one end of the cylinder.

Referring more especially to the drawings, 1 and 2 designate the main rails, and 3 and 4, the siding rails, and 5 and 6 the switch oints, which are pivoted at 7 to one of t e ties 8. The siding rail lmerges into the main rail 2, at a po nt beyond the extremity of the switch points 6. The ties 8 and 9 are provided with =wear plates 10 and 11. A portion of a section of the main rail 2 is secured to one of the plates 10 by the spikes 12, whereas the main rail 1 and the siding rail 4: are secured to said plates 10 and 11 by the spikes l3 and 14. It is to be noted that the plates 10 have raised portions 15, between portions of those rails that are secured stationary to the tie 8, thereby holding said rails spaced. In other words, the rails 1 and 3 are held spaced apart, as well as the rails 2 and 4. At a point where the side rail 4: merges into the main rail 2, it is secured to the tie 16 by the spikes 17. The main rail 1 is also secured to the tie 16 by means of the spikes 18. The spikes 17 and 18 pass through the plates 19 which are on the tie 16. The main rail 1 and the siding rail 4 are secured to the tie 20 by the spikes 21. The free extremity of the switch point 6 has an inwardly extending flange 22 to which is con nected by means of a bolt 23, a bar 24.. The bar 24 is in turn secured pivotally by means of a bolt 25 to a flange or lug 26, which projects inwardly from the switch point 5. Mounted in suitable strap bearings 27 is a rock shaft 28 having a crank 29, to which a link 30 is pivotally connected. The link 30 is in turn pivotally connected by means of a pin 31 to one end of the bar 24-. Suitable nuts 32 are secured upon the rock shaft 28 adjacent the inner ends of the strap bearing 27, to prevent axial movement of the rock shaft. One end of the rock shaft is provided with a right angle extending arm or lever 33, and by grasping the same, the rock shaft may be rocked substantially a half revolution, so that by means of the crank 29, movement is imparted to the bar 24:, to throw the switch point from a closed position as shown in Fig. 1 to an open position, as shown in Fig. 3, which is a sectional View on line 3-3 of Fig. 1, showing the switch points open. A pair of straps or-elongated plates 31 C and 35 have their Opposite ends secured by bolts or other suitable means 36 and 37 to the ties 16 and 20. Integral with the straps or plates and 35 is an elongated cylinder 38, which is suspended below said plates or straps, and n between the ties l6 and 20. The bar 2i 18 also below the straps or plates and in between the said ties, and by so disposing the 4:1, and its other end is pivoted to the flange 22 of the switch point 6 by means of a bolt 43. A collar piston 4-l is secured ad ustably on the rod 42 by means of a. set pin 45. This collar piston fits the cylinder 38 near its end opposite the cylinder head 41: and interposed between the collar piston and said cylinder head and surrounding the rod 42 is a coil spring 46, which coiiperates between the cylinder head and the collar piston'to hold the switch points normally in the positions shown in Fig. 1. WVhen the rock shaft 38. is moved in the direction of the arrow (1, the switch points are thrown to opened positions ast the action of the spring 46, and when ti 2 arm 33 is moved toward and between the staples d7, by rocking the shaft in the direction of the arrow a, so that the U-bolt of a padlock, not shown. may be connected to thetwo staples i7, the switch points may be held in such opened positions. However, just so soon as the padlock is removed the switch points will be automatically thrown to the closed positions shown in Fig. 1, by the action of the spring 46, and in this case, thearm 33 will fit be tween the staples 48, which may receive a padlock, not shown. However, when the flanges of the car wheels are acting upon or against the switch points to move them from their open positions in Fig. 3 to their closed positions in Fig. l and the padlock has been detached from the staples 47, the spring will assist in moving said switch insane? points, thereby relieving excessive strain upon the switch points.

The invention having been set forth, what is claimed as new and useful is 1. Inaswitch mechanism, the combination of a pair of main rails and siding rails, of a pair of switch points, spring means having connection with one of the switch points for holding the switch points normally closed, and means manually operated for opening the switch points against the action of said spring means, said spring means comprising a tubular cylinder, a pair of straps connecting two adjacent ties and supporting said cylinder below the upper surface of the ties, a third strap secured to said ties and having acylinder head integral therewith, for one end of the cylinder, a piston rod guided in said cylinder head and provided with a collar piston and having one end connected to the end portion of one switch point, and a coil spring on the said piston rod between the collar piston and the cylinder head.

' 2. In a switch mechanism, a pair of main rails and siding rails, a pair of switch points coiiperating between the main and siding rails, an elongated cylinder having integral transverse plates connecting two adjacent ties, whereby said cylinder may be supported below the surface of the ties between said switch points, an additional transverse plate connected to and supported upon said adjacent ties and having a circular plate depending downwardly therefrom fitting over and closing one end of said cylinder,

a rod guided in said circular plate and hav-' ing an angular portion at one end terminating in lateral forks, means for pivoting said forks to the base flange of one of the switch points, a piston head on said rod and movable in said cylinder and being located normally at the end of the cylinder opposite the circular plate, a spring interposed between the head and the circular plate to hold the switch points closed, and means connected to the other switch point and adapted to be released, whereby said switch points may be opened against the action of said spring.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
