BRAKE-HANDLE.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed October 26, 1917'. Serial No. 198,598.

To all whom it may concern:

Be it known that I, BERNARD SOHECHTER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Brake-Handles, of which the following is a specification.

This invention consists of improvements in brake handles of the drop type, which require less room for their operation, and in which the ratchet means is engaged only, during the use or operation of the brake. The dropping of the handle causes disengagement of one ratchet from the part'that operates the brake.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,

Figure 1 is a sectional view showing the parts in. operative position;

Fig. 2 is an end elevation. showing the parts disengaged from operat1ve position;

Fig. 3 is a sectional view on the line 3- 3 in Fig. 1, looking in the direction of the arrows;

, Fig. 4 is a section on the line 44 in Fig. 3, looking in the direction of the arrows;

Fig. 5 is a view on the line 5r5'in Flg. 2, looking in the direction of the arrows; and Fig. 6 is a view on the line 66 1n Fig. 2, looking in the direction of the arrows.

The brake handle 1 is pivoted on screws 2 which pass through the cam lugs 3 forming. part of thehousi g 4.. Y

The brake staff 5 rises through the car floor (not shown in the drawingslbeing connected at its lower end with the brake rigging and at its upper part being received in hollow ratchet bearing member or collar 6 and fastened therein and thereto by pins 7.

. This is more convenient than present practice, which is to weld together the staff and "a stud depending from parts supporting ratchet members.

At its top ratchet bearing member 6 terminates in enlarged portion 8, the upper edge of which is provided with ratchet teeth 9 adapted to grip and coiiperate with ratchet teeth 10, both of which ratchets are inclosed in collar 11 which is fastened by a pintle 12 having up-set ends 13 to collar 11 and to member 21.

The stat! 5 passes pivotall v through the center of the hollow member bearing ratchet 9 and its continuation2l passes through the hollow member 14 bearing the ratchet 10, screws 2 abutting the same after passing through the cams 3 and the wall of hollow member 14. The stop 15 engages on the outside of the wall of hollow member 14 whenv low member 14 and when the handle. is inthe position shown in Fig. 1, the said spring 17 forces ratchet member 14 hearing the ratchet 10 into engagement with ratchet 9, which ratchet 9 is in fixed relation to brake stafi 5 by reason of the pins 12 and 13 and rotates therewith. When, therefore, handle 1 is in the position shown in Fig. 1, ratchets 10 and 9 are gripping each other and circumferential movement of handle 1 in the desired direction will cause ratchet 9 to turn brake staff 5 and to apply the brake. When this has been accomplishedit is unnecessary to return the handle 1 to its initial position or to do anything with it except to allow it to drop by gravity, which results in cams 3 raising ratchet 10 out of engagement, with ratchet 9 because handle 1 is pivoted by screws 2 to ratchet member 14.

The exterior of hollow member 14'is' polygonal at 19 (preferably rectangular) in order to cotiperate with the angular interior of the housing 4 at the'point where the said housing comes in contact with the exterior of the hollow-member 14. By means of'this polygonal engagement, when the handle 1 ered position, covers the spring 17 and top of the continuation 21 of brake staff 5 and thus forms a structure in which there is a saving of metal because of the cam or cam members 3 serving the double function of collars and housing, while the ratchet in closing collar 11 serves the double function of acting as such inclosure or housing and also to afford a bearing for the cam or cams 33 step-'20 limits the downward movement of handle 1.

V'Vhile the spring 17 is convenient to keep the upper ratchet member spring pressed when not disengaged by the positiveaction spirit of thissinvention, omit-he scope of the following claims.
