PECIFICATION 'forming-part er Lettere Patent No. 689,762, dated Deeember 24, 1901.

Application filed March 7, l1901.

To all whom it may concern.:

Be itknown that I, FREDERICK C. TAYLOR,

to afterward utilizing the power which is ordinarily wasted in operating a brake, and, second, to provide a device of this class in compact form and of suitable structure to operate 'upon either a forward or a backward rota- '15 tion of the shaft to which said device is ap I accomplish these objects by the plied. mechanism shown in the accompanyin g drawings, in which- Figure 1 is a vertical longitudinal section of a brake constructed according to my inven-` tion. Fig. 2 is a vertical section on the broken line 2 2 of Fig. 1. Fig. 3 is a vertical section, partly broken away, on the line 3 3 of-Fig. 1. Fig. 4 is a reduced vertical section on vthe line 4 4 of Fig. 1.

The device shown in the drawings consists mainly of an axle, a sleeve loosely mounted on said axle, a wheel loosely mounted on said axle and having a iiange overlapping said `gorsleeve, a coil-spring connecting said sleeve with said wheel, suitable clutches for independently connecting said axle with said sleeve and said wheel, and suitable mechanism for stopping either said wheel or said sleeve. v Y

The axle 1 is partly broken away in the drawings, the car-Wheels being omitted on each side. The sleeve 2 and'wheel 3 are each loosely journaled on said axle. The flange 4 4o is rigid on thewheel 3 and has the outer end of the coil-,spring 5 secured thereto. The inner end of the spring 5'is secured to the sleeve 2. The sleeve 2 is provided with a'web 6,'

having an outer annular surface 7 for engagement with the brake-band 8. The wheel 3 has an outer annular surface 9 for engagement with the vbrake-band 10. The annular surfaces'7 and 9 are each preferably confined between the annular flanges 11. The

i' 5o sleeve 2 has a liange 12 secured thereto bymeans of the bolts 13. The wheel 3 has a simi-l la'r flange 14 secured thereto by means of the .tion of the wheel 3.

bolts 15. The collars 16 andV 17 are loose on the axle 1 and are cut away for the collars 18, which are tight on the axle 1 and which serve to prevent the shifting of the parts longitudinally of thevaxle 1. The clutches 19 and 2O are splined to the axle 1 and normally held in engagement with the collars 16 and 17 by means of the springs 21. Said springs act against the collars 22, which are tight on the axle 1. The levers 23 and 24 are pivoted at 25 and 26, respectively, to the framework of the car, which is not shown. Said levers are forked and provided with rollers 27 operat- -ing in `thegrooves 28 of the clutches 19 and 20. `The collars 16 and 17 are provided with the recesses 29, 4carrying the rollers 30. Said rollers kare normally urged forward by the springs 31, so as to bind between said collars and the respective flanges 12 and 14. Each of said collars inconnection with its rollers forms a clutch permitting its rotation in one direction with respect to the opposed iiange acted upon by said rollers and preventing reverse4 rotation.

The brake-band 10 is preferably made of spring metal and is secured atV 32 to a suitable part of the frame of the car. 33 is pivoted at 34 to said framewand has the .links 35, pivotally connecting same with the brake-band 10. When the upper end of the lever 33 is in the position shown, said band will be tight on the ,surface 9, and will thus stop the rotation of thel wheel 3. When the The lever.

upperY end ofthe lever 33 is moved toward theleft ofthe position shown in Fig. 2, thel band 10 'will be loose around said surface 9. The brake-band 8 is constructed and operated in. similar manner to the brake-band 10. vThe operation of my device is as follows: When the parts are in the position show n in Fig. 1 and with the brake-bands 8. and 10 loose on their respective surfaces, the entire device will rotate with the axle 1 in the direction of the arrow. To stop the c ar, thev operatorywill set the brake-band 10y `tight upon the annular surface 9, and thus stop the r0- The axle 1, withthe sleeve 2 and collars 16 and 17, will continue to rotate and wind up the spring 5 around The tension of the spring act- IOO ingl between the wheel 3 and the sleeve 2 will tend to stop the rotation of the sleeve 2. The

roller-clutch will act upon the collar 16, so as to stop the axle 1 with the sleeve 2. -The clutch 19 prevents the relative rotation of the axle 1 and the collar 16. After the ear is stopped the operator will release the brakeband 10. The roller-clutch between the collar 17 and the flange 14 serves to hold the wheel 3 against such rotation of the axle l as would unwind the spring 5. To utilize the spring-power in helping to start the car, the operator will now set the brake-band S and then release the clutch 19 from the collar 16. The Wheel 3 will now be acted upon by the spring 5, so as to rotate in the direction of the arrow shown on the axle in Fig. 1. The rollerclutch acting between the Wheel 3 and the collar 17 will rotate the axle 1 in the direction of the arrow, the clutch 2O being in engagement with the collar 17. If the bands 8 and 10 are both released after the spring has been wound up and while both clutches 19 and 2O are in engagement with the collars 16 and 17, the power of the spring will not be utilized in propelling the axle, but may remain stored for future use. To aid in backing the car after the power has been stored, the operator will set the brake-band l0 and release the clutch 20.

It will be understood that numerous details of the device shown may be altered without departing from the spirit of my invention. I therefore do not confine myself to such details except as hereinafter limited in the claims.
