(no me To all whom it may c n rn: of the car -body in rear of the car-axle and lie it known thatLWIi iIARD F. RICHARDS, firmly connected with the body. In the cona citizen of the United States, residing at Bufstruction shown in the drawings the front ends falo, in the county of Erie and State of New of the tracks are secured to a bracket F and 5 York, have invented a new and useful Imtheir rear ends to a strap or bracket F, which provementin Electric-Lighting Apparatusfor brackets are bolted to cross-pieces fastened Railway-flare, of which the following is a to the car-sills.

The carriage is preferably 2o dynamo toward the axle and causes a slippage provided with four. rollers, as shown. The

of the belt, which neutralizes such increase dynamo is capable of rolling npon'its supof speed, thereby maintaining the dynamo at porting-tracks toward and from the car-axle the predetermined normal speed. An apps.- and is pressed away iromthe latter for keepratus of this kind is described and shown in ing the belt tight by eisniteble tension device. my application for patent, Serial No. 651,840, Either of the tension devices shown in the filed September 16, 1897. drawings may be employed forthis pill-pose,

' The objects of this-invention are to support That shown in Figs. 1 and 2 is constructed as, the movable dynamo by simplemeans which follows:

arranged lengthwise on the under side the enter of said hearing, by which conthe follower I.

a suitable detachable wrench, and the openi ng in the car-floor is preferably closed by a removable cap or cover, as shown. By this construction the follower I in the normal operation of the, dynamo forms a fixed abutment for the tension-spring, which latter tends constantly to force the suspended carriage and the dynamo away from the caraxlefby bearing against the bottom of the socket I, mounted on the carriage, thuskeeping the driving-belt taut. The motion of the car-axle is. transmitted to the armature-shaft of the dynamo so long as the speed of the latter remains at or below the normal; but

as soon as the speed rises above the normal" by the increased speed of the train t-he'increased pull of the belt resulting therefrom overcomes the weight of the dynamo and the resistance of, the tension device andd'raws the dynamo toward the car-axle, thereby slackening the driving-belt, allowing it to slip on the driving-pulley of the dynamo. and

permitting, the speed to fall to the normal, when the dynamo will again more away from the ear-axle under theforcc of the tensionspring and tighten the belt and so maintain the normal speed and output of the dynamo. By means of the operating-shaft and adjusting-screw the tension of thedriving-belt can be regulated forobtainiugauypredetermined output of the dynamo.

In the modified construction of the belttensioning device shown in Figs. 3 and i the tension-spring and the socket and follower coOpera-ting therewith are arranged as in the first-described construction; but a vertical ad'ji'isting-sercw O and an elbow-leverv l are substituted for the" operating-shaft N, the horizontal adjusting-screw J, and the conmeeting-gearing m n. This elbow-lever is pivoted to the bracket F by ahorixontal pin p, and its lower arm is pivoted to the head of The upper arm of the lever carries a swiveling-nut q, with which the lower portion of the adjusting screw O engagcs. The upper portion of this screw journalcd in a bearing-r, arranged in an opening of the car-floor, and is held against vertical or endwise movement in said bearing by socket I, WllGlQbjillO tension of the spring is changed accordingly.

)By supporting the. dynamo in the manner herein shown and described the same remains atall times in the same position relatively ,to its carriage or support and does not affect or modify the action of the driving-belt when the latter becomes stretched' more or less, so that the tension of the belt is affected only by the tensio'ndevice. As the dynamo rolls on a level track orsupport, the friction is rednced toa'minimum, rendering the apparatus sensitive in action. The apparatus is, moreover, simple and inexpensive in construction.

I claim as my inventiour 1. The combination with the ear-body and the driving-axle provided with a pulley, of a longitudinal track arranged on the underside of thccar-body, .a carriage mounted on said track and carrying a dynamo provided with a pulley, a horizontal socket mounted on said carriage, a follower applied to said socket, a prcssure-spring arranged between said socket and follower an ad 'ustim device connected with said follower, and a belt applied to said pulleys and extending in a substantiallyhorizontaldirection from the driving to the driven pulley, substantially as set forth.

I 2. The combinatioirwithiherar-hody and a ear-axle, of a longitudinaltrack or-way arranged on the under side of the car-body,a carriage mounted on said track and carrying a dynamo, a horizontal socket mounted on Said carriage, a tubular fullowcr applied to said socket, a tension-springarranged in said socket and follower, an adjusting-screw engaging with said follower, and an upright o crating shaft geared with said adjustingscrcw, substantially as set forth.
