To all whom it may concern.-

Be it known that I, ALE ANDER PALMRos, a citizen of Finland, residing at Columbus, in the county of Franklin and State of Ohio, -have invented certain new and useful "Improvements in Motor-(Jars, of which the following is a specification, reference being had therein to the "accompanying drawings. In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying it intopractical efifect wlthout llmltlng my n'nprovements in their useful applications to the particular construction whichfor the sake of illustration I have delineated.

In salddrawlngs, Figure 1 1s a slde View of an electric locomotive embodyingmy invention. Fig. 2 is a plan view, partly in section,

on line II II, Fig. 1. Fig. 3 is aside view of the driving-wheels and themeansfor connect ing them to each other and to the frame.

. Fig. is a vertical section on line IV IV, Fig. 2.

Referring to the drawings, the main frame of the locomotlve is composed of'side bars or frames A A and end bars B B, fitting the former at the lowerparts of their end faces and having inwardly extending vertical flanges which lie within the side frames and are secured thereto by bolts a; cast or otherwise constructed of great strength and weight to give the necessary tractionpower.

The side frames are each formed with three or more spaces a a a -to accommodate the suspension devlces, herelnafter descrlbed, and

between said spaces with vertical bars or col- On the tops of the boxes are supported I These parts are I springs F, located in the longitudinal planes of the frames AA in the upper parts of the spaces a a and secured by boxes, straps, or

brackets f, which surround and are attached to the springs and are seated in recesses e ml the journal-boxes. At their ends said springs are connected with suspension-bars G G, as by means of apertures f, provided in the versely in'the bars and resting in recesses f in the upper sides of the ends of the springs. The said suspension-bars form a series, occupying portions 'of the spaces a a the end bars G of which are connected with the main frame of the locomotive. Such a connection is conveniently effected by forming the frames and weight the frames A A are formed with vertical longitudinal webs a=at the inner sides of the spacesa a and connecting the guides a with the bodies of the frames, and to balance the strain on the pins 9 the inner ends of the latter are seated also in apertures a in the webs a"; The pins may be held in place by heads on theirouter and cotter-pins in their ends. The strains of thesprings on the bars G are transmitted from one to the other of said bars, as the strains vary and are equal ized through movable connections. In the construction illustrated said connections comprise levers H, each having a substantially central fulcrum on a transverse pin h, seated in an aperture a in the side frame and secured in place by a cotter-pin 72,.

The guides a are connected at their lower ends by strap-bars a, secured to the frame by bolts a. i

The wheels D D and D D are formed with flanges d, while the intermediate pair of wheels D D are without flanges and engage only the top surfaces of the'rails.

The equalizing mechanism herein described springs, through which said bars G pass, and

jby cross-pieces, pins, or saddles g, fixed transis much superior to any of the sorts heretofore known as concerns use with a motor-ear or electric locomotive of the character of that herein presented. Cars like the present one are intended for use in mines and similar places where the track is narrow, has many sharp curves, is irregularly laid, and frequently covered by obstructions, such as pieces of coal, rock, and the like. The cars must be exceedingly short and the parts thereof very compactly arranged in small compass. They must be very heavy in order to provide sufficient traction. By employing the intermediate unflanged wheels D, I am enabled to prevent the loss of traction efficieney, for if either of the driving-wheels D or D should move up or escape from the rails its motion and the momentum of the neighboring part of the ear is instantly transferred to the intermediate wheel and more or less to the other driver.

In another respect the ear herein differs from the earlier constructions employing equalizersnamely, in this that each of the axles and its pair of wheels are driven independently of the others, there being independent motors I, I, and I geared to the axles, respec'tively. The motors are arranged as shown, those at I and I extending in one direction and that at I in the opposite direction, whereby there is left an open chamber or space at I to receive the driver and wherein can be placed the several levers and operating devices, such as those for controlling the motors, the brake mechanism, &c. As the central wheels D D are unflanged, the binding or cramping of the car when turning sharp bends is obviated.

What I claim is 1. In a motor-car, the combination of the body or main frame having the side framepieces formed with chambers to provide spaces to accommodate the wheel-suspension devices, such spaces being arranged within the outside and inside wall-faces of the frame-pieces, and being also provided with journal box guides, the axles extending from one of the said spaces to the opposite one, the wheels arranged in pairs upon the axles, and the equalizingmeehanism interposed between the wheels and the car-body and arranged in the said spaces, substantially as set forth.

2. In a motor-ear, the combination of the body having the side frame-pieces formed with chambers opening outward to provide spaces in which are mounted the wheel-suspension devices, such spaces being between the planes including the outside and inside wall-faces of the side frames, and being separated by the vertical bars a the journal-box guides arranged outside the said spaces, the axles extending from one space to the opposite one, the wheels arranged in pairs upon the axles, the journal-boxes arranged in the said guides in which the axles are mounted, and the equalizing mechanism interposed between the wheels and the car-body and arranged in the said spaces, substantially as set forth.

3. In a motor-car or locomotive adapted for use in mines, the combination of an inclosing main frame, the lower edges of the sides of which come close to the track, and which sides are formed with external chambers or recesses, the motor devices arranged within the inelosing frame, the traction-wheels, and the suspension devices arranged between the wheels and the frame and situated within the said recesses or chambers, substantially as set forth.

4. In a locomotive or motor adapted for use in mines, the combination of the main frame having the side frames formed with the vertical longitudinal webs a", outside of which are arranged chambers or recesses, the motor devices arranged inside of the said webs, the traction-wheels, the supporting-axles of which pass through the said webs, and the suspension devices arranged between the tractionwheel axles and the frame and situated in the said recesses or chambers, substantially as set forth.

5. In an electric locomotive of the elassdescribed, the combination of a locomotiveframe, three axles, means for holding said axles permanently in parallel transverse planes, the unflanged wheels on the intermediate axle, the flanged wheels on the other two axles, three independent motors, each eonneeted with one of the axles and driving it independently of the others, and the equalizing-spring-supporting system interposed between the loeomotive-frame and the said axles, substantially as set forth.

6. In a motor-ear the combination of the body or main frame, two outer driving-axles, two independent motors independently geared to said outer axles respectively, the two pairs of the flanged driving-wheels one pair on each of said axles, the third axle intermediate of the two outer axles, the unfianged track-engaging wheels secured to the ends of the intermediate axle, the independent journalboxes for the said axles mounted in vertically-disposed ways, and equalizing devices arranged between the journal-boxes of the flanged wheels and the journal-boxes of the unfianged wheels, substantially as set forth.

7. In a motor or locomotive, the combi nation of the main frame, the traction wheels arranged in transversely-disposcd pairs, one pair in advance of the other, independent vertically-movable journal-boxes for the wheelaxles, supporting-springs arranged between the journal-boxes and the frame, equalizing devices arranged between the springs of one pair of wheels and those of the other pair, and independent motors, one for each of the said pairs of wheels, the wheels being unconnected, whereby they may be driven independently, substantially as set forth.

8. In a motor or locomotive, the combination of three pairs of wheels and their carryingaxles, independent vertically-movable supports in which the said axles are mounted, springs arranged between the several axles and the frame of the motor, equalizing devices arranged between the two outer axles and the intermediate axle, and independent motors for each of the said axles and pairs of wheels, the wheels being non-coupled whereby the wheels may be driven independently and whereby each pair of wheels is adapted to follow the track independently of the other pair, substantially as set forth.

9. Inan electric locomotive of the class described the combination of a locomotive-body, three axles, means'for holding said axles in transverse planes permanently parallel to each other, a pair of track-wheels on each axle, the three track-wheels on each side of the locomotive being held permanently in the same longitudinal planes, three electric motors each connected with an axle and driving it independently of the others, an equalizing-springsupporting system for said axles interposed between them and the main frame, said equalizing system being at .its ends flexibly connected to the main frame and pivoted to the scribed, the combination of the locomotivebody having an iron side wall formed with a t series of cavities in its outer face, three axles mounted in the said body and held permanently in transverse planes parallel to each other, vertically-movable boxes for said shafts respectively,- a spring bearing upon each box andarranged within one of the said cavities in the iron side wall, a pair of links for each spring arranged within one of the said cavities, and levers pivoted to the said wall on axes between the said boxes, the outer links of series being pivoted to the said wall and the intermediate links being respectively connected to the springs and to the levers, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses. Y
