. certain new and useful Improvements in Electric-Railway Cars, of which the following is a specification. a

' The present invention comprises certain improvements in the truck,the motor supporting frame and its combination with the motor,-

the power transmitting mechanism, clutching and speed regulating apparatus therefor, and braking devices, all of which will first be fully described with reference to the accompanying drawings, and then pointed out in the claims.

In said drawings Figure I isa plan view of a motor truck embodying my improvements. Fig. II is a side elevation of the same, one wheel being partly broken to show the clutch and brake mechanism. Fig. III is an axial sectional view of the epicyclic gearing. Fig. IV is a sectional view of the clutch and brake mechanism. Fig. V is a plan of the-truck, with motor removed illustrating the clutch and brake mechanism. Fig. VI is a plan view I partly diagrammatic-parts of the motor truck and car platforms illustrating the application thereto of my improved air brake and other parts. Fig. VII is a detail view showing the operatinglever or the three-way valve. Figs. VIII, IX and X are sectional views illustrat- Fig. XI is a detail plan view of the three way valve casing and its operating mechanism adjacent thereto.

Thelinvention relates in part toa peculiar truck and a specially constructed motor chm-- bined therewith, but certain parts of the invention are not limited to use on this improved truck, nor, indeed, to-use on a truck at'all, but may be applied to cars having the ordinary street-car construction. The axles lof track-wheels 2, are joined by rigid longitudinal .bars '3, having inside bearings 4 on upper arch of the field magnets bears a center pin which maybe cast in one with the core and which enters a socket-plate 11 on the carbody, indicated at 12, The spring 13 placed between thefield magnet core-and plate 11 aifords a--yielding support to the car-body. The weight of the car-body thus rests on the motor-field-magnets and thence on the truck frame, so that, in eifect, the field-magnets form a part of such frame and add to its rigidity. The armature-shaft 14 is carried in hearings in the center of the bars 3 and midway between the axles. The commutator brushes 15 are supported by arms or brackets 16 from one bar 3 and the support of the-armatureshaft in this bar may be an ordinary boxing 17. At the other side of the truck, the said shaft passes through a sleeve 18 whiclis formed on or rigidly fixed to the internal gear 19 of myplanetary power transmitting and speed reducing gear. Such gear, as herein illustrated, is in part of thesame construction as that described and claimed in my application Serial No.- 325,244, filed September 27,

1889. It comprises the internal gear 19, in

which the armature-shaft turns freely and which itself turns by'its sleeve 18 in its bearingin the'bar3; the pinion 2O keyed or pinned to the armature-shaft in the'plane' of the teeth the armature-shaft and bearing a wrist-pin 23 engaging the'center of a rigid connecting rod 24 in the ends of which engage wristpins 25 on the car-wheels; and intermediate pinions 26 keyed orpinned to pins 27 mounted so as to rotate'in disk 22. The disk 22 has a curved. huge 28, surrounding the internal gear 19 and a packing ring 29 of any suitable mate rial interposed between said flange and gear excludes dust from the gearing and renders it noiseless and capable of retaining lubricants.

The operation of the gearing is as follows: The armature is a constant running one, pref- 'erahly' of slow speed. .While the current is on, therefore, the shaft 14 and its pinion 2Q revolve constantly, and drive the intermediate pinions 26. It now, the internal gear 19 be held fast, the intermediate pinions 26 will travel around 'in it, carrying withthem the 21 of gear 19; the disk 22 free on the end of the internal gear is locked, the car will move in the direction of rotation of the armature I characterize this arrangement of the internal gear and the means whereby it may be held fast or let run free, as a slip support the idea being, that the internal gear maybe fixedly held, or allowed to run freely on its support or to slip thereon under any desired, regulatable, frictional resistance.

The 'meansfor holding the gear fast or allowing it to run free is what I refer to in the.

claims as a yielding liquid abutment, and as herein. illustrated, it comprises an oscillating cylinder adapted to contain water andhav-- Said liquid clutch comprises a pinion keyed to the sleeve 18 'of the internal gear; a spur wheel 31 having wrist 32 and running on a stud or pin 33 projecting from one of thcbars 3; a plunger-rod 34 having one end pivoted on said-'wrist and bearingon the other a plunger 35; a cylinder 36 in whichs'aid plunger plays, hung so as to oscillate in brackets 37 or other support on the truck frame, and having a gateway or by-path 38 connecting its opposits ends; a valve 39in said path controlled by an arm 40 which is connected by rod 41 with a lever or levers 42 on one or both car platforms. I

Any suitable arrangement may be adopted to prevent the oscillation of the valve 39 in the by-path in synchronism with the oscillation of the cylinder. I In order that said valve may move with the cylinder in its oscillations and may nevertheless be shifted by move-.

ment of the lover or levers 42, the connection of the rod 41 to the arm 40 may for,example A be by pin and slot 43, as shown. -By shifting one of the levers. 42, the valve 39 may be either opened or closed. It opened, free passage is allowed through the by-path for the liquid which fills the cylinder and by-path .and the movement of the plunger will not be materially resisted by the liquid. -The' rotation of the train of gears and pinions 20, 26, 19,30 and 31 under the action of the :armature will be free and unresisted, so that the armature will turn and actuate such train of gears, without driving the car. But, it by the shifting of one of the levers 42 the valve-39 be closed, the flow of the liquid is arrested stopping the movement of the plunger and locking the train of

gears

19, 30 and 31, so that, as before described, the intermediate pinions 26 traveling on the internal gear semen .19 will. carry with, thsm'ths diskttland its accompanyingreclprocstingcouncction.with

the car-wheels, thus propellingthc car at the full speed corresponding to the maximum speed o 'rntation of the armature; -'It willbc seen that opening the valve. stops the movemeut'oi the car and allows the armature to operate continuously. Closing the valve moves the car with a fixed connection. Between these two extremes any desired speed of movement at the car is attained by a corresponding opening of the valve and removal theretoreot resistance to the movement-ct the plunger. I describe this variable lock or clutch for my diiIerentia-l gear, and heroinafter reterto it in the claims asv a yielding liquid abutment. In vcohnection with this yielding liquid abutment (and reterably act- 'uated by the rigid connectiont erewith herein shown) is an air or vacuum. brake, which I will now describe. In this connection it is noted that for the reason that itis desirable the end 44 of t 0 cylinder 36 and bears the plunger 45- of the air pump- 46 which has usual connecting pipes 47 (controlled by valves 48) with reservoir 49, valved pipe and brake cylinder 61. The plu'nger'52 of such brakecylinder is connected to brake the yielding abutment be.

lever 53 which is hung from any suitable part of the carer truck and has usual rods 54con- .nected to the brake beams 5. Connected to the reservoir 49 I place a, whistle 56 which is under the control of valve 56 at the motor mans hand on .either platform of the car. Seeing that the plunger45 with its positively connected mechanismis in this device only in action while the. car is standing still or moving at reduced speed, it is only at such times that energy is absorbed in operating the air pump oi the brake system.

. In Figs. VI to XI I have illustrateda form oi. my invention in which the liquid pump is 1 omitted and the motion of the gear 31 is transmitted by rod 34 directly to the piston 45. in the cylinder of the air pump 46. 67 is the air inlet of the air pump having ports 58 0011? necting the opposite ends of thesaid pump.

Dischapge ports 59 of the pump connect with the pipe 47. Reversing valves are shown at 60 having the cross head 61 under-control of the piston rod 34. The valves are reversed att-he end of each stroke and during the running of the gear 31, a practically constant compression of air through the pipe 47 is ct-' footed. The reservoir is shown at 49 having eoe,311- a inlet pipe 47 and combined inlet and discharge pipe 47". The brake cylinder is shown at 51 having an air supply pipe 50. The

pipes

47, 47, 47? and all communicate with the casing 62 of the three-way-valvez' The form of the valve and its'method of operation ,areclearly seen in Figs. VIII, IX andX. On turning to the positionshown-in Fig. VIII which is the same as that shown in Fig. VI, the air pump 46' pumps air through pipe 47 through the three-way valve and through the pipe 47 and 4'7 into the reservoir49 (acheck valve 64 in pipe 47 prevents return movement of the air). In this position the brake cylinder 51 is open phere through pipe 50 and the port 65 of the three-way valve. In the position of shown in Fig. IX-airis 47 and port65 into the external atmosphere again. Pipes 47 and 4:7 three-way valve and connection is madeby the pipe 50 and port 66 of the'three-way valve with the brake cylinder. In this position the brake is 'on and the pump is Working freely in the atmosphere without resistance. After the car has stopped with the three-wayvalve in this position by turning the valve to the position the three-way valve pumped through pipe shown in Fig. VIII and releasing the brakes by the spiral the back pressure of the compressed air in reservoir 49 is caused to re-act through

pipes

47, 47 and 47 on the piston 45 and so accelerate-the starting of the car.

In the posit-ion shown in Fig. X the pump is connected by the port 66 of the three-way valve with both the air reservoir 49 and the air brake cylinder 51 so asto supply air directly to both simultaneously while the pipe 47 although arranged opposite the open port of the three-way valve discharges no air therethrough owing to its retention by check valvefi i; With the valve in this position, the back pressure of the reservoir air acts automatically to start the piston 45 in action on the releasing of the brakes after the stopping of the car. The means for turning the threeway valve to either of these three positions are exhibited in Figs. VII and XI. "lhe valve staff extending through the top of its casing has a pinion 67 engaging with a rack 68 on a .rod 69 which runs from end to end of the ear and is connected at 'each end to a.lever 70 pivoted on the car platform at 71 and adapted to be oscillated by a handle be removed and carried from one platform to the other. The valve 56 controlling the whistle 55 is held normally in closed position spring 73 and has a handle or lever 7i whose opposite ends have connected to them rods 75 leading to the opposite plat- 72 which may forms of the car and there brought'under the control of the operator by a lever similar to that shown in Fig. VII or otherwise.
