CONTROLLER FOR STREET-CARS.

Specification of Letters Patent.

Patented Apr. 26,1919.

Application filed August 2, 1909. Serial No. 510,902.

street cars, and more particularly to a mechanism-for governing the movementof acontroller lever or handle.

The objects of my invention are to provide a controller with simple and efl'ecti-ve. means for governing the thrmving-on movement of the controller lover or handle, and to furnish a controller casing with a novel plate adapted to limit the movement of the controller lever;

Other objects of lIlyiIlVGlltlOll are to provide'a Controller with a novel mechanism I that Wlll prevent the motorman or operator of the car from suddenly starting the same, and to provide means for retarding the throwing-on movement of a controller lever, thereby preventing the motor from being burned out by a too rapid application of power to a-car.

These and su chother objects as may hereinafter a pear'are attained by a mechanism that lias been designed for all branches of electric service, for instance, for regulating the power to motors on electric cranes, to hauling and coal mining motors, and can be used for regulating and controlling various power feeding apparatus.

My power regulating device will be here inafter described in detail and then claimed.

Inthe drawings: Figurel is a front clevation of a portion of the controller equipped with my improved mechanism,

Fig. 2 is a plan of the same, Fig. 3 is a front elevat1on of a plate forming part of the cou- .troller, Fig. 4 is an enlarged longitudinal sectional view. of the controller le-ver or handle,. and- Fig. '5 is a bot-tom plan-o1 the same.

circular retarding plate 2; said plate having jut my invention into practice, 1 proa central opening 3 with the wall of the.

opening provided with avertical groove 3, for a purpose that \\'1ll hereinafter appear.

The plate 2 is provided with depending equally spaced supports 4 adapted to rest upon the mechanism within the controller l. The plate 2 is provided with a circumferentially disposed slot 5 of a length approximately three-quarters the eircumterenee of the plate 2. The slot 5 has the inner wall thereof oil-set, as at- 6, and provided with beveled lugs 7,-thesc lugs extending into elf-set portions 8 of the outer wall of the slot. The outer wall of the slot isalso provided with beveled lugs 9.extending into i the oti'setportion 6 of the slot: 5-, thus proriding a staggered. irregular or'sinuo'us slot extending from the power-oil point 10 of the controller to the fp nver-on .point'lli The lever used in connection with the con,-

'top thereof provided with a longitudinal ijrih 1 3, said rib providing a longitudinal groove H in the under side of the top of the casing. In the groove 14 is placed a spring or resilient strip of metal 15 adapted to bear upon an oblong head lt'i-earried by a depemlingpin 17, said pin being triangular in cross section to provide two beveled sides 18. "lhe head 16 is loosely held in an oblong frame 19 arranged within the casing 12, one end of said frame being connected to a sleeve 20 and extending through the open ing 3 of the plate.2, said sleeve providing a socket 21 for the upper end of the controller shaft (not shown). The'sleeve20 is pro vided with a vertical rib 20, and this rib must aline with the groove 3, before the troller 1 comprises an oblong casing 12 havsleeve 20 can be placed in the opening 3 of the plate 2. The opposite end of the frame 15) is provided upon one sidewith a lug 22 adapted to engage in openings 23 and 2t provided therefor in one of the' longitudinal side walls of the casing 12.

The frame 19 is retained in position by a cover plate 25, said plate having a longitudmal slot. 2610 provide clearance for the pin 17. The inner end ofathe plate 25 is provided with opp disposed lugs 27 to engage in notch 3'1; provided therefor in the longitudinal slilfwalls of the casing .1 .jswung whereby the 12. The opposite or outer'en d of -the plate 25 is provided with an enlargement 2'.) engaging the top of the oblong casing 12, and

with an openingBO, to receive a depending 5 screwbolt 31 carried by .a handle 32, said handle and screw bolt being held in eng'agement with the casing 12 by a nut 33, said nut also holding the cover plate 25 within saidcasing. The cover plate is of a less 19 length than the casing 12, consequently the" casing 12 can be shifted upon the frame 1-9, .1; Withthe controller lever iii-position, the pinl'l is adapted to extend into thenregu- ;--J lar slot 5 of the circularretarding plate 2, 15 and to swing the lever from thepomt 10 1' of the plate 2 it is necessary to shift 'the casing 12 back and; forth upon the frame 19, n-otherWisethe pin 17 would engage the lugs [T and 9 an'dfpreve'nt the lever from being moved. The r ame l9 loosely. 'fits within. the casing 12 and has sufiicient lateral movement "In startin the lever from the '2..f,-and. i1nmed1ately upon the'pin;l7 eon- -tactin with the first lug 9,- the casing l2 isjshi ted or -ushed inwardly toward the a ,verticle axis 0 the plate 2. This movement ll ef, the casing causes tliejlu 22 to register Qwith the opening 24, and after the-lever is H in 1'1 impinges the first lug 7 the leveris 'pu led outwardly, whereby .he-casin ,win shift to movejthepin 17 l cl'ear of t e lug? and allow of a further throwing-on movement of the controller lever; This operation is continuous until the. fpower-on point is reached, and from thls point the lever'can be easily and quickly swung to the point 10 owing to the'beveled f faces18 of the pin.17 allowing said pin-to j ride over the inner irregular walls of the .islot 5. The spring 15 is of sufiicient tension "to frictionally holdthe head 16' in engagemen't with the cover plate 25,-and in swingfing the controller lever, the lug 22 of the "frame 19 will enga e in one ofthe openings j 23 or 24.- In provi ing the openings 23 and :24 and the lug 22, it is impossible for the operator of the controller lever to rapidly manipulate or jump Hue la 7. and 9 for jtliisreason'. When the pin 1 engages one of the lugs, the lug 22 extends into one of 'enings' 23 or '24=,-and beforethe cash1g0 the controller lever Iean be shifted, the

" lever -must,be"movedbackward a short dis tancofrom thelu -Zor9to allow thelug tomove-jout o either the opening 231or1 24', .Thecasinggcm then be shifted and'when :m gq he nexf, lufg of the plate .2 is encountered;

In devising my improved controller mechanism, l have aimed to obviate the trouble experienced by inexperienced or green motormen in operating street cars. It is a well known fact that the public experiences considerable discomfort, often resulting in injury, by a motorman suddenly starting a car, and considerable expense is incurre ou the part of street car. companies b the motors being burned out by the power'heing lator also prevents the operators of mill cranes ,and motors lfor hauling purposes being started too suddenly.
