To all whom, it' may concern,.-

V Be it known that I, LOUIS PFINGST, of

Dorchester, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in P owerBrakeS, of which the following is a specification.

Mfr invention relates to limprovements in Y power-brakes, and especially to brakes which 1o are ladapted to be applied by motive powerl Jfor transmitting motive power to the chain--k winding brake-spindle; to lprovide an varrangement for automatically engaging the 'motor-power clutch members by an electric '1 circuit;to. provide an arrangement forcut- 3o ting out `the .clutch .memberscircuit by anotherelectric circuit or by manual operation; to automatically cut in the current flowing tothe motor to rotate same; to cut out said Current by manual effort, so that in case' thel motorman desertshis car lforany reason the brakes will befautomatically applied, and by this lautomatic. arrangementl a plurality of spindles can be Set in motion to .set the brakeson one or more cars. These y4c and other objects are accomplished bythe fmechan'ism hereinafter described and shown. f My invention consists of' certain novel features'hereinafter described, and particularly pointedout in the Claims.

Fast on the motor-shaft C is a driving clutch member D', and located in suitable recesses on the exterior of the clutch member D are two bands of brass D2 D3, which are suitably connectedto the ends of The circuit-closing bracket/ E is supported by the upright arm B3 ofthe bell-crank lever B3 and carries the 'upper and lower contact-wheels E E2, suitab y Insulated from the bracket, as shown, .the wheel E2 acting as an inlet and the wheel E acting as an outlet, ythereby forming an electric clutclncircuit-closer.

E3" is a magnetic solenoidattached to the base-frame, which cooperates with the metal pin. B7, pivoted on the arm B3, and can be actuated '.when the magnetic wire is ener-y gized. The energizing of said wire is` accomplished bythe switch'E3 being closed by the olperatorlacing his -footon the-inner part of t e trea E3, which will operate the lever- 'arm'B3, pivote'd at E3 to the'lever B2. The extreme end E7 lof the leverarm B3 is insulated, as shown, so `as to prevent the current. passing oil and compel it to pass through the wire 7 in t'the'rnagnetic solenoid E3 and thence outlto the ground. by the Wire 8. thisoperationthe upright -arm B5 of the bel cran-k lever B2 is ulled away from the magnetic clutch mem `er D', breaking the electric contact on-the bands D2 D3. This will deenergize themagnetic clutch, allowing the lower clutch member D to separate from the upper .member D by gravity. With the clutch members in this released position the operator` canrotate vthe-'motor-armature C or allow itv tostand still at'will. It will be understood that when Ithe' mechanism is inv this. released position the motor is running free and is not a'ctingvupon the spindle`C3, as no motion is communicated to the gear C..

.The o eration of the switch E4, as ,above describe will when suitably connected by the wire-circuit cause the operationof a plurality of motors and spindles o n the dit-v ferent cars for train service. i

Itv will be'further understoodthatthis operationwill release one or all of the brakes by the operation of one or a' plurality of motor mechanisms located on one or a plurality of cars comprising a train F is an enlarged diameter of the motor base-frame B, forming a socket for the in. sertion. of the lower end of the motor-frame F. and secured by suitable bolts F2 and bolts F3, which latter pass through.I the motorfra'me C tothe -pole-pieceFj, (see Figs. 5 and 65,) securing all man assembled positron.

.H5 is a boss formed on the under side of Vthe top of the extension-frame G, forming an upper .bearing for the motor-armature shaft C.

H3 H7 are insulating-bushings for the purpose of insulating the brush-holding brackets H3.

:H3 is a metal washer between the bushing H7 and the jam-nut H10, said nut meshing with the thread H11 on the lowerend of the boss H5. This nut H10 is used for the purpose of fastening the brush-holding arrangement in 'a Aiixed position' after the brushes are set. The' brush-holding arms J J are secured tothe bracket H3. The brushes K K make contact with the eommutator K2.

On the upper end of the motor-armature shaft C and within said cap is ixed the ratchet dog or clutch K5, engaging with the companion ratchet member or dog K3, which is held from rotation by the bolts K7 passing through the walls of cap K3, the points of which iit in slots on the companion member K3'y and allow a vertical movement of said member K". This member K6 is held in engagement with the member by the spring K3, interposed between the under side of the cap K3 and the top of the member K". The

ratchet mechanism is for. the purpose of holding the motor-shaft from' a reverse rotation. when the motor-power is cut out inthe after 'application of -the brakes from the bra-ka.

G3 is a boss on theltop of the extension-- frame G, forming with the hole G3 a guide and bearing for the upper end of the brakespindle C3.

,L is a motor-armature havingits arma-v tureshaft provided with extended ends, as show1r,'wl1ich are journaled in the boss B4 and boss H5.

By the aboveid'esc'ribed construction the motor-armature is held in place. j The-loose. clutch member D is connected to 'the gear C, formin part thereof, 'by means of the throat C, an said member is ada ted toal ver-tical movement' on the loweren .of the motor-armatureshaft C. On the upperj end of the `brake-spindle C3 is mounted a lhand-power handle provided withmechanism' to permit the s indle C3 to rotate freely in the chamber M o saidhandle when the spindle isdriven by motive-powerwi'thbut turning the handle M'. Normally 't e' v hand-le M is disengaged from' the brake-spindle C3. To engagesaid handle when desired to operate the spindle 55 by the. wire 5, thence to the' brush K', to the aaneen by fhandower, the operator, placing his f hand on-7te'top 'of the handle, will depress -t 'ough be conveyed to 'the bell-crank lever M5, which the plunger M2 against thel resiliency oi the s" ring M 'housedv in the handle M, and the rod-M4 a downward pressure will ,i's'pivoted on the forked bracket M1", termed onflthe underv side of the handle M, causing the other end ci the bell-crank lever to move inwardly toward the brake-spindle, pressing on-the plunger M7, which is 'driven into one of Vthe orifices M8, formed on the nxed hub M ci neet the handle 'from the spindle, the operalshaft N'-, supported by the brackets i 2 and the bearing N3 'end thereis mounted the handle N4,

ytor releases the pressure from the plungerM2 and springs M3, withdraws the pin M7 from the-spindle-hub M5, leaving the brake-spin.- dle Ma free to be revolved without the handle bythe motive power.

Themotor current-controller N consists of a in the frame G, and on its upper which y can'be removed, if desired'. This handle i 4 is arranged-to rotate the shaft N' against the spring N5, secured at one end ,at N6 to the ,frame G and attheother end to the shaft N Mounted at or near the lower end of the shaft N'- is the contact-arm NS, which suports the contact-plate'N", which is insulated om it bythe strip O: Directly opposite on the hub of said arm is Jformed the quadrantratchet circle P, with which coperates the awl P', pivoted on the bracket P2 by the pin 3.' The ratchet-circle and the pawl are for the purpose-'ofholding the contact-arm' N8 out of thefelectric circuit when not in use. A The bracket Q is secured to the frame G by suitable bolts and carries the terminal posts -R R', suitably insulated, as shown, from the bracket Q.; The intake-wire Iv is connected with the post R, and the intake-wire 2 is convnected with the postV R', receiving current from the trolley-wire when the contact-plate WN covers both, after which the current will 'low through the Wire 2, insulated from the post R',

to the motor lield-wire 3, which is a continuation .of the wire 2, and the circuit then passes into the field-coils 4, Fig. 5,

wind up the chain C4 thence to the brushlholding arrangement J' through the brush K the wire to the ground'.l Theoperation of rotati to' apply the. brakes .on

` one vor more cars is as follows: The operator disengages the pawl P' from the quadrant- "ratchet circle P 'from the position shown in Fig.' 2, when the spring N5-Will cause the fopng the Spindle c? w" erator to use pressure on the end N4 to 'keep the contact-plate N from closing the circuit. At will the operator may release said pressure on the4 handle Ntfwhen the' spring lN5 will automatically act to cover V the binding- `posts R R' by the plate N9, whichwill close lthe circuit tri allow the current to ilo-w from its source'across the plate N to the post R', thenceto the wire 2, to the wire 3(which isa continuation ol the wire 2,) passing through the fields 4 thence to the wire to the brushholding arm d" passing out through theI brush K' to the commutator K2, through the brush K to the arm J, and te the groundy by the wire 6. This ilowof current will rotatel the' armature L and the extended arn'iatiire-V vshafts C, which will rotate the clutch member D'. N ow to operate the spindle C3 to apply the brakes the operator breaks thel circuit through the switch E by releasing the pressure on the tread E5, and the spring 'E8 will then iorce the insulated part E7 el the lever B5 from the switch E4, thus breaking the circuit through said switch E2, which denergizes the magneticsolenoid E3, and this releases the metal pin B7 fromgits magnetic .in-l

fluence, permitting the arm B5 -of, thebellcrank lever B to move inwardly bylineans of the spring E10.V This will force into contact the wheels E' E2 with the bands D2l D3. While this operation takes place the endE7 of1 the lever B closes the switch E", thereby lowing the current to 'flow through thewire 9 to the wheel E2, to the band D3, throughthe magnetic wire D4 to the metallic band D2,

out through the wheel E', thence to the ground by the wire 10. As explained, the 7 metallic clutch memberD' will. by itsmagnetic influence exert an attraction onthe'- lower clutch member D upwardly, .bringing IOO into contact the inclined surfaces of each member and holding the clutch in engagement, and thereby rotating the gearC,which will transmit power to the gear C2, fast on the spindle C2, rotating said s indie to wind up the chain C4 and set the rakes.y Thegear` C2 being of larger `diameter than the gear C" causes a multiplication of ower in the application oi the brakes. if t e spring E8 should become broken or otherwise lose its tension, the o erator can press on the outer end of the treay E5 of the lever B6 and causethe engagement of the end E7 with the switch-E2. With the brakes applied, as above described, the o erator can open the motor-circuit, keeping t e clutch members engaged, and the brakes nwill be automatically held by the ratchet or dog mechanism K5 K6, located in the cap. K,

W'hen desired to release the In the diag,` fimmatic view, Fig. 12, there is shown a pluv ility of solenoids and clutch members in .circuit for train-service, and the construction shown is embodied in the braking apparatus on each end of the'cars in Figs. 1 to 9. f To energize the two solenoids of one car or more in a train, the switch E4 is closed by the operator, as above described, which closes the circuit through the Wire 7- and solenoids E3, and the current passes by the wire 8 to the ground. The continuation of the current to thel next car is 4through the kwire S and coupling connection S, thence tothe next car connected with the wires 7 and S through the solenoids E3,.thence to the Wire 8 to the ground. In this manner the operation of the ,apparatus by the operator at the head of a train releases the brakes by rotating the spindles, due .to the usual 4brake-spring .pull throughout the entire train by means ofthe electromagnetic solenoid-circuit in a manner similar to thatpreviously described for one car.

To apply the brakes by the rotation of the brake-spindles, the switch E4 .is opened, which denergizes the solenoids, and -the switch E9 is clos ed,-which energizesl the mag# 'netc clutch, attractin .the clutch members to engagement, which c utch members are rotated by the motor-shaft C, which has been previously put in rotation, asvhereinbefore described. The source of current for the Wire-.circuit for one or all of the clutch members is-similar to the solenoid-circuit-that is, the source of supply comes from the Wire 7 through theI switch E9 and -wire 9 through each upper clutch member D out to the ground by the wire 10.

The electric circuit for the'clutch members for one or a train of cars is by means of the wire T and, coupling T.

Having described the circuits for the solenoid Vand the clutches, the motorcircuit (shown in diagrammatic view, Fig. 13 )will be described. The wiring for the motor-circuitv is las follows: The source' of supply is from the wire 3, which is a. continuation of the Wires 1 2, and the manner of starting thc mojtor or motors is by throwing the arm N8 to cover the posts RR which will allow current to flow through the motor or motors, as

shown by the wiring, and out to the ground.

by the wires 6.. U is'a coupling' placed between the cars for train-'service and with the wires U'carries the current through the train.

- TW and TR) or from any source.

As shown in Figs. 10 and 11, the construction ofthe platform and car-bottom frame consists of buffer-timbers A with a platform- :liooring b. c c c c are the supporting-timbers, fastened to the'body of the car-and supporti ing the flooring b and buffer-timber A. d is the end sill, which is fastened to the extreme end of the side sill e. i f represents the bottom# frame cross-timbers, which are fastened to the side sill e to support the flooring. To the end .sill d and side sill e the end frame and side frame of the car are secured in the usual manner of car-building. gis the main brake-rod, and at one end of said rod is connected the brake-chain C4, and the other end is pivotally connected to vthe center brake-lever h. The main or center brake-lever. h is supported by the buacket t, secured to the bottom ofthe car, and has an equalizing-slot The said brake-lever hV is' held in place by the pin' c.

Pivotally connected-to the center brake-lever ward and are connected `t0 similar mechanism at the right-handend ofthe car.` The operation of this mechanism is as follows:

By rotating the spindle Caz and winding up the 'chain C4 the brake-rod g vwill be pulled forward, thereby actuating the brake-lever h. This will pull in the opposite direction the secondary rods Z, and by `this operation the secondary rods will pull the truck-levers m toward the center'of the car, pressing out the bottom end of the levers m toward the end of the car, causing the brake-beams p to travel inthe opposite direction, and thereby apply the brake-shoes'to the-wheels. By the arrangement of the spindle with the brake-handle, as hereinbefore described, the spindle can revolve in either direction Without rotating the handle, or the handle can be rotated in either direction without rotating the spindle or motor, or, if desired, the handle can rotate the spindle without rotating the motor or operate both at the same time. To lrotate the motor-armature Without current, the clutch member D is brought into engagement with the clutch member D by the foot-lever arrangement, so that by the rotation of the. 1 handle when the clutch members are engaged the gear becomes operative from the spindle to the armature-shaft, thereby enabling the same to be rotated.
