T 0 all whom t may concern.'

Be it known that I, Jol-IN VILLIAM TAG- ERT, a citizen of the United States, residing at Stamps, in the county of Lafayette and State of Arkansas, have invented certain new and useful Improvements in Car- Brakes, of which the following isa specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in adjustable hand operating brake mechanism for railway cars, the object of the invention being to providea hand' brake which can be quickly and easily operated when disposed either in a vertical or horizontal position.

Another object of the invention is to provide improved means for locking the brakes after they have been applied, said means being adapted to be easilyreleased so as to free the brakes.

A further object of the invention is to providel a brake mechanism ofthe above character which will possess advantages 1n `points of eliiciency and durability, is inex-l pensive to manufacture and at the same time is simplel in construction and operation. y

With the above and other objects in view, the invention consists rin the novel features of construction and the combination and ar-` rangement of parts hereinafter morefully described, pointed out in the claims, and shown in the accompanying drawings in which- Figure 1 is an elevation. Fig. 2v is a vertical sectional view. Fig. 8 isa sectional view on the line BH3 of'Fig. 2. Fig. 4 is a vertical sectional view illustrating a slightly modified form.

Referring more `particularly to the drawings, 1 indicates the car `upon the end of which is mounted the supporting bracket 2, extending upwardly from thel base of the bracket and formed integral therewith are the two spaced ears 3 each` of which is provided with an opening 4 adapted to receive the tubular member 5 in which the lower end of the rod 6 is mounted. Rig-idly mounted upon one side of the supporting bracket 2 is a curved rack bar 7 upon which is adjustably mounted the bifurcated extension 8 which isl formed integral with one side of the collar 9, said collar being suitably secured to the lower end of the tubular body member 10.

Slidablyrmounted in the eye bolt 11 is the ,positions YThe lower end of the rod 12 is held securely in engagement with the notches 14 by means of the coil spring 15 which is mounted ,upon the rod and arranged between the' eye bolt 11 and the engaging member 13. The member 13 at the lower end of they rod 11 is adapted to be removed from'the notches 14 by means of the pivoted handle member' 16. Mounted upon the upper end of the body member 10 is a U shaped supporting member 17 which is provided with upwardly extending spaced arms 18 infwhich is mounted the shaft 19 having a beveled gear20 mounted thereon and a1'- ranged'between the arms. Mounted upon .the upper end of the rod 6, which extends upwardly through the body member 10, is

a second gear 21 adapted to mesh with the gear`20 so that when the hand wheel 22 ywhich is mountedupon the outer end of the shaft, is turned lthe rod 6 will be rotated to wind up the brake chain 23 and set the brakes.

Mounted within the flanges 24 upon the outer face of the arms 18'is a ratchet 25 which is adapted to be engaged by a similar ratchet 26 mounted upon the shaft 19 to vhold the brakes in a locked position until it is desired t0 release the same. In winding up the brake chain, the hand wheel 22 is 'pulled toward,y ther operator to disengage the ratche'ts 25 and 26 so as to leave the wheel 4free to be turned and rotate the shaft 19 and the gear 21 which in turn will rotate the rod 6 through the gear 20 and wind up the brake chain 23. After the chain 23 has been tightened so as to set the. brake, the hand wheel 22 is pushed outwardly to engage the ratchets25 and 26 and lock the brake in its operative position.

l From the above description taken in connection with the accompanying drawings it will be readily apparent that my improved brake operating mechanism willbe espeycially valuablev upon fiat cars or other similar cars which are used to transport logs,

telephone poles, etc., as the device may be adjusted and arranged in a horizontal plane so as to be entirely out of the way in case the logs or telephone poles should extend beyond the ends of the car.

Fig. 4, I have illustrated a slightly modified form of the invention wherein the hand wheel 22 is arranged directly at the upper end of the body member 10. In this form of my invention, the hand wheel 22 is mounted directly upon the upper end of the rod 6, and the supporting member at the upper end of the body member l() is provided upon each side thereof with the flanges 26 in which is mounted the ratchet 27 adapted to engage with a similar ratchet 2S secured to the central portion of the hand wheel 22. In operating this form of mechanism, the hand wheel 22 is to be rotated in one direction to wind up the brake chain 23, the ratchets 27 and 28 preventing backward movement of the wheel. After the brake chain 23 has been tightly wound, the ratchets 27 and 28 will engage each other to hold the wheel 22 against rotary movement and when it is desired to release the chain 23, the wheel 22 is pulled upwardly to disengage the ratchets 27 and 28 so as to allow the wheel 22 and the rod 6 to rotate and unwind the chain.

The rod 6 is provided adjacent its upper end with a transverse opening 29 in which is arranged a pin 30, the ends of said pin being arranged in the space between the top end of the body member l0 and the ratchet 27 to prevent the body member l0 from sliding upwardly upon the rod 6.

Frein the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a simple and durable brake operating mechanism of the above character which can be quickly and easily operated when arranged in a vertical or horizontal plane and which at the same time can be manufactured and applied to various varieties of cars at extremely low cost.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features of construction or departing from the scope thereof.
