To all whom it may concern.'

Be it known that I, FREDERICK C. Cosuo, a citizen of the United States, residing at Columbus, in the county of Franklin and the State of Ohio, have invented certain new and useful Improvements in Brake Mechanism, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to certain new and useful improvements in brake mechanisms adapted to'be 4used with industrial locomotives, and especially with that class of industrial locomotives in which the motive power is supplied by a single electric motor connected with the axles of the locomotive through suitable gearing.

It is commonly desirable that the motor man in charge of such locomotives should connect and disconnect the couplings between the locomotive and its load, thus avoiding the employment of an assistant. Y To this end it is expedient that the motor man should ride at the end of the locomotive next the load, and that the controlling mechanism should be equally accessible from either-end of the locomotive.

One object of this invention is to provide improved retarding devices, operable from either end of an industrial locomotive,

-which shall effectively retard the rotation of the driving wheels of said locomotive.

A; further object is to provide convenient locking devices, adapted to retain such retarding devices in effective relation to the moving parts of the locomotive, which may be locked from either end of the locomotive,` and which can be released from the end at which they were locked, or from the oppo-A site end as convenience may require.

The Adevices by which I attain these objects are fully set forth in the Jfollowing specification and illustrated in the accompanying drawings of which:

Figure 1 is a side elevation of a locomotive equipped with my improved brake mechanism, the side frame being broken away to show the motor and brake mechanism.

Fig. 2 is a plan view of the locomotive illustrated in Fig. 1, the cover plates being removed.

Fig. 3 is a detail side view of one of the brake applying hand levers shown in working relation to its notched arc.

ldrive the locomotive.

Fig. 4 is a plan view of the parts shown in Fig. 3.

Fig. 5 is a detail showing of certain parts shown in Fig. 3.

Fig. 6 is a detail view of the brake wheel and the parts associated therewith.

Fig. 7 is an assembly of the brake mechanism detached from the other part of the locomotive. v

Like numerals refer to similar parts in the several figures.

In Figs. 1 and 2 I have shown, for purpose of illustration, a locomotive having a mainframe composed of the side plates 1 and 2 joined'together by the cross plates 3 and L1 and by the end frames 5 and 6 on which are mounted the bumpers 7 and the draw bars 8. The locomotive is supported upon the rails 9 of any suitable track by the driving wheels 10 fixed to the Vaxles 11 and 12 journaled in journal bearings 13 suitably connected with the side plates 1 and 2 of the locomotive frame.

The axles 11 and 12 are connected together by the driving chain 14 which engages the sprocketwheels 15 and 16 keyed to the axles. Fixed to the .aXle 11 is a nonoverhauling worm wheel 17 in driving engagement with the worm 18 of the worm shaft 19, which is connected with the armature shaft 20 of the motor 21 by a suitable shaft coupling 22, to In the locomotive here illustrated power is supplied to the motor 21 from the storage battery 23, but, it is to be understood that, this arrangement of parts is immaterial to the spirit of the present invention, and that where operating conditions will permit, any suitable method of supplying current to the motor may be employed, as by the well known trolleyand trolley pole.

Mounted upon the cross plate 3 of the locomotive frame is a controller 24 by which the motor 21 is controlled. The operative parts of this controller are connected with a shaft 25 extending longitudinally of the locomotive, and supplied at each end with a hand wheel 26 affording means for the manipulation of the controller at both ends of the locomotive.

The motor 21 is mounted upon a suspen sion bracket 27 having at one end bearings 28 which engage the axle 11 and supported at the other end by a cross lbar 29 from the side plates 1 and 2 of the locomotive frame.

.the hand lever 45 will be pressed forward Nearone end the suspension bracket 27 is shaped to form a. gear case 30 inclosing the worm wheel 17 and having suitable bearings 31 and 32 in which the worm shaft 19 is journaled. The worm shaft 19 is. eX- tended beyond the bearing 31 and to this eXtensionis liXed a brake wheel 3.3 adaptedl to be clasped by the brake shoes 34 to retard the rotation of the worm shaft 19' and' through it the axles 11 and 12 to check the movement of the locomotive. rlhe brake l shoes 34 are joined at their` lower ends, and

device by which the shaft may be rotated to engage or diseIlgagc the brake shoes 34 with thev brake wheel 38. As theseoperating devices' are alike a description of one will apply toJ both. Fixed at the end of the shaft 40 adjacent the cross plate 3 is a hub4 41 having. a lateral extension 42 upon the face of which is formed a lug 43 which is engaged bythe fork 44 of the hand lever 45. A hinge bolt 46 connects the lever 45 toV the lug 43 for limited rotation in a plane longitudinal of the shaft 40. A compression spring 47, interposed between the extension 42 and the lever 45, tends! to force them apart and an eXtension 48vv of the fork 44 serves, to limitv the outward motion of the lever 45. Formed on the lever 45'is a knife edge fiange 49 adapted to engage the notches 50 of the arcuate angle bar 51 attached to the cross plate 3 concentric with the shaft 40. By this arrangement the shaft 40 may be rotated, by pressure applied tothe hand lever 45, to cause the brake shoes 34 to engage the brake wheel 33: When the shaft 40 has made afsufiicient rotation'to produce the desired pressure on the brake shoes 84,

untily the knife edge 49 engages one of the notches of the arc 51 to prevent rotation in the reverse direction and maintain the pressure upon the brake shoes. If now it is desiredto release the brake from the opposite en 'd of the locomotive it willV only be necessary to apply a rotative force in the brake applying direction upon the hand lever 45 at that end of the locomotive to allow the disengagement ofthe knifeedge 49 fromA the arcv 51 when the splil1g47 Will force the lever 45 to its outer, or free postoh leavliongkthe shaft 40 free to rotateto release the .ra e.
