AUXILIARY PILOT FOR RAILROAD-TRAINS.
Specification of Letters Patent.
Patented Jan. 9, 1912.
Application filed January 30, 1911. Serial No. 605,435.
To all whom it may concern Be it known that I, ISAAC WoLPER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Auxiliary Pilot for Railroad-Trains, of which the following is a full, clear, and exact description.
My invention relates to devices for sounding an alarm in the cab of a locomotive when there is an obstruction on the track, and it has for its object to provide means adapted to close an electric circuit on the contact of an auxiliary pilot truck with an obstruction on the track, the electric circuit being adapted to energize a solenoid for opening a valve in the train pipe, and also for ringing a bell in the cab of the locomotive.
Other objects of the invention are to provide means for extending the auxiliary pilot truck a distance in front of the locomotive when the pressure in the train pipe is normal, and for drawing the auxiliary pilot truck in the direction of the locomotive when the pressure in the train pipe has been reduced to operate the brakes, and to provide means for controlling by hand the said means for moving the auxiliary truck relatively to the locomotive.
Additional objects of the invention will appear in the following complete description, in which the preferred form of my invention is disclosed.
In the drawings similar characters of reference denote corresponding parts in all the views, in which- Figure 1 is a side elevation of a locomotive provided with my device; Fig. 2 is a fragmentary sectional view showing the reel with its electrical connections, on which the wire extending from the rack member is wound; Fig. 3 is a sectional side elevation of the auxiliary pilot truck; F ig. 4 is a sectional view on the line 44 of Fig. 3; Fig. 5 is a sectional view on the line 5-5 of Fig. 6; Fig. 6 is a plan view of Fig. 5 with portions broken away to show the construction of the parts; Fig. 7 is a diagrammatic view showing the electrical connections and the members associated therewith; and Fig. 8 is a fragmentary sectional view showing the method of connecting the rack member with auxiliary truck.
By referring to the drawings it will be.
seen that the locomotive 10 is provided with a truck 11 having two axles 12 and 13, on which are mounted clutch members 14 and 15, there being gear wheels 16 and 17 integral with the clutch members 14 and 15 respectively. The said clutch members 14 and 15 with the said gear wheels are mounted so that they may rotate relatively to the axles. Additional clutch members 18 and 19 are provided, having annular grooves 20 and 21 respectively. These clutch members 18 and 19 are keyed to the axles 12 and 13, and are adapted to slide thereon so that they may be moved into or out of engagement with the clutch members 14 and 15. Pivoted to brackets 22 secured to the frame of the I truck 11 there are bell crank levers 23 and 24, to one set of arms of which are secured pins 25, which are disposed in the annular grooves 20 and 21. The other arms of the bell crank levers 23 and 24 are connected by a link 26. Fulcrumed to a bracket 27 on the frame of the truck 11 there is a lever 28, the' link 26 being articulated to one arm of the lever 28 at 29. To the other arm of the lever 28 there is articulated a piston rod 30, which projects through an opening 31 in the head 32 of the cylinder 33, mounted on the truck 11. This piston rod 30 is secured to a piston 34, a spring 35 being wound around the piston rod 30 between the piston 34 and gaged by the gear wheel 16. The gear wheel l7 meshes with the gear wheel 47 mounted on a shaft 48 journaled in bearings in the truck 11. The gear wheel 47 is adapted to engage the teeth 46 of the rack member 45. The forward terminal of the rack member 45 is secured to the auxiliary pilot truck 49, which has axles 50 on which are mounted wheels 51. A headlight 52 is mounted on the auxiliary pilot truck 49. At the front of the auxiliary pilot truck 49 there are secured projecting brackets 53, to which are v secured an insulated member 54 having a transverse opening 55 in which is disposed a conductor member 56. Around the forward portion'of the insulated member 54 there is disposed a conductor member 57. having radially disposed openings 58, whichopposite side by the conductor links 63.
There is an orifice 64 extending longitudinally through the rack member 45, and in this orifice 64 are disposed wires 65 and 66, these wires 65 and 66 projecting through the forward end of the rack member 45, the wire 65 being connected with a binding post 67 on the conductor member 57 and the wire 66 being connected with the binding post 68 at one end of the conductor member 56. The wires 65 and 66 project from the rear of the rack member 45, and are led to the reel 69. This reel 69 has a drum 70 on which the wires 65 and 66 are adapted to be wound, the reel being provided wlth a spring 71 for rotating the drum 70. The hub 72 of the reel 69 has two insulated conductors 73 one communicating with the contact point 74 at one side of the reel, the other communicating with the contact point 7 5 at the other side. The insulated conductors 73 lead to contact plates 76 on the drum 70 of the reel, to which the wires 65 and 66 are secured. The contact points 74 and 7 5 are engaged by spring contact members 77 mounted on brackets 78 secured to the bearings 79 of the reel 69. The wire 80 secured to the spring contact member 77 leads to the solenoid 82 and thence to a bell 83, and from thence to the battery 84, the wire 81 secured to the spring contact member 77 leading to the said battery 84. The solenoid 82 is provided with an armature 85 to which an arm 86 is articulated, this arm 86 being connected with the valve 87 which is in communication with the train pipe 39. The engineersbrake valve is shown at 88, and the reservoir tank on the locomotive is shown at 89. To the arm 41 of the valve 40 there is articulated a link 90. this link 90 being articulated to a bell crank lever 91, which in turn is articulated to a hand bar 92, by which the valve 40 may be readily opened or closed by the engineer. To the lever 28 there is articulated a link 93, which 'is commanded by a lever 94 in the cab of the locomotive.
V In using the invention the rack member 45 Will be projected forwardly with the auxiliary pilot truck 49 when the locomotive wheel47, the teeth of the gear wheel 47 engaging the teeth 46 of the rack member 45 to project it forwardly. WVhen the rack member 45 has been projected forwardly a predetermined. distance, the continued rotation of the gear wheel 47 will merely hold it in this relative position, since the teeth 46 are not continued to the rear terminal of the rack member 45. When the auxiliary pilot truck 49 reaches an obstruction on the track the conductor links 63 by contacting therewith will be driven against the contact member 57, which will close the circuit previously described, and will ring the bell 83 in the cab of the locomotive, and also open the valve 87 by means of the solenoid 82. When the valve 87 is opened the pressure in the train pipe 39 is reduced which will apply the brakes in a well-known manner. The reduction of the pressure in the train pipe 39 will also permit the spring 35 to press the piston 34 to the right, thereby operating the lever 28, so that the clutch member 19 will be moved out of engagement with the clutch member 15, and the clutch member 18 will be moved into engagement with the clutch member 14. WVhen the clutch member 18 engages the clutch member 14, the axle 12 which rotates with the wheels 96 Will cause the gear Wheel 16 to rotate, and as this gear Wheel 16 engages the teeth 46 of the rack member 45, the said rack member 45 will be drawn rearwardly relatively to the locomotive.
It will be understood that the reel 69 will at all times take up any slack of the wires 65 and 66 which may be occasioned by the movement of the rack member 45 relatively to the locomotive. By means of the lever 94 and the link 93 the lever 28 may be moved as may be desired without reference to the pressure in the train pipe, and as has been described, this lever 28 will, by the link 26, the bell crank levers and the clutch members, connect the rack member 45 so that it will be projected forwardly in front of the locomotive or it will be withdrawn at the will of the engineer. The rack teeth 46 do not extend to the auxiliary pilot truck 49, and when the rack member 45 is drawn rearwardly relatively to the locomotive the gear wheel 16 will be moved out of engagement with the rack teeth 46. By means of the hand bar 92, the bell crank lever 91 and the link 90, communication may be cut ofl between the cylinder 33 and the train pipe 39 at the will of the engineer.
It will be understood that when the lever 94 is in a vertical position by the means described it will hold both clutch members 18 and 19 out of engagement with the clutch members 14 and 15 and that when it is moved in one direction it will move the clutch member 18 into engagement with the clutch member 14, while when it is moved in the opposite direction it will move the clutch member 19 into engagement with the clutch member 15.
A hook 97 is secured to the locomotive and is adapted to engage an eye 98 on the auxiliary pilot truck 49 for holding the auxiliary pilot truck 49 close to the locomotive. The auxiliary pilot truck may be dis engaged from the rack member by removing the pin 99 which connects the auxiliary pilot truck with the rack member and completes the electrical connection.
