CYONTROLLR FOR MOTOR-CARS.
SPECIFICATI'ON forming peut ef Letters Patent Ne. eeose, dated December 2o, 189e. Application filed December 30, 1897. Serial No. 664,604. (No model.)
To @ZZ whom, t may concern:
Beit known that I, ARTHUR PILLsBURY DODGE, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvementsin Controllers for Motor-Cars, of which the following is'a specification.`
My invention relates to a controlling system for motor-cars and involves the use of hydraulic means extending from the cabs to the brake system, to the cylinder-cocks, and to the link-motion or reversinggear, said means being actuated and controlled by a group of devices or controllers arranged at the ends of the car.
In the accompanying drawings, Figure 1 is a detail view, partly in section, of the controller. Fig. 2 is a similar view to Fig. 1, taken from a point at a quarter-turn therefrom.
The controlling devices of this invention are intended for use in connection with motors of the Dodge type, in which a boiler 'and driving-engines are arranged beneath the car-bottom, the same being controlled by devices preferably at the ends of the car. These controlling devices are grouped upon a main frame 1, and they comprise a central shaft 2, having a screw-threaded lower endv 3, forming a part of a steam-controlling or pressurereducing valve 4 below the main frame and the carplatform, which valve controls the pressure of the steam passing to the cylinders. This central shaft 2 is operated by a hand-wheel 7. Surrounding the shaft is a sleeve 8, having a hand-wheel 9 and having at its lower end a bearing in a yoke on the main frame. The gear-wheel 12 is fixed to this sleeve and meshes with a pinion 13, having a nut 15 attached thereto, engaging a screw-threaded portion of a rod 14, adapted to slide in the yoke, the lower end of the rod carrying a piston moving in a cylinder 15', which cylinder is held between the yoke 11 and the main frame or casting l. From this cylinder the hydraulic connection 16 extends to the reversing mechanism or link-motion, so that by turning the hand-wheel 9 the hydraulic medium between the cylinder 15 and the link-motion will be actuated to set the latter as desired.
The cylinder 15 is located to one side of end of the piston-rod of the piston 18.
The motor is controlled as to speed by the operation of the hand-wheels 7 and 9, the former controlling the reducing-valve and insuring a known initial pressure,'while the latter controls the reversing mechanism or linkmotion. e
I claim as my invention-'- 1. In a motor operated by steam or like pressure, a boiler, a controller comprising a valve, a central shaft, a hand-wheel connected therewith, a piston and a cylinder on one side thereof connected with brake mechanism by a hy- IOO draulc column, a piston and cylinder on the brake-cylinder, substantially as described.
2. In combination in a motor operated by steam or like pressure, a valve, a hand-wheel and shaft for controlling or adjusting the same, a reversing mechanism, a piston, a cylinder and means for operating said piston consisting of a sleeve surrounding the shaft 2, a nut threaded on the piston-rod, a pinion secured to the nut, a gear on the sleeve and meshing with the pinion and means for turning the sleeve, the said cylinder being arranged parallel with the shaft, with means for supporting the parts, substantially as described.
3. In combination, a controller for steam or like motors, consisting of a valve, a central shaft connected therewith, a cylinder on each side of said shaft and parallel therewith, a yoke bolted to the tops of said cylinders, a sleeve surrounding the shaft, gearing extending laterally therefrom within the yoke and connected with the piston of one of the cylinders, a hand-lever, the bracket pivotally supporting the same, the pinion-andrack connection between the hand-lever and the other piston and means for supporting the parts, substantially as described.
4c. LIn combination in a controller for steammotors and the like,a pressure-reducing valve, the brake and reversing cylinders arranged adjacent to and parallel with the shaft which operates the valve, the sleeve surrounding the shaft and having connection with the piston of the reversing-cylinder, the hand-lever connected with the piston of the brake-cylinder, the casing inclosing the cylinders, a cylinder outside of the casing having a footpiece whereby its piston may be operated, said cylinder having connection with the cylindercocks with means for supporting the parts, substantially as described.
5, In combination in a steam or like motor, a valve and means of operating the same, reversing mechanism, brake mechanism and cylinder-cocks, duid-pressure regulating connections leading to the brake mechanism, reversing mechanism, and cylinder-cocks and controlling devices in the car comprising pistons and cylinders for controlling said iiuidpressure, said cylinders being arranged adjacent and parallel with each other and means for supporting the cylinders, substantially as described.
G. In combination in a motor for steam or like power, a valve, a cylinder having liquid connection with a reversing mechanism, ,a second cylinderhaving liquid connection with the brake mechanism, hand-operated devices for operating the pistons of said cylinders, fluid-pressure connections leading to thecyb inder-cocks and the foot-piston for controlling the pressure in said connections, the said cylinders being set vertically and parallel to each other and having vertically-operating pistons, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
