WAGON-BRAKE LEVER.

SPECIFICATION forming part of Letters Patent No. 400,565, dated April 2, 1889.

Application filed January-l1, 1889- Serial No. 296,072. (No model.)

9,.formed with a catch-tooth, 16, which en- .70 (L whom, it 72mg concern.-

Be it known that we, WILLIAM A. HANEY and ENOGH G. I-IANEY, both of Media, in the county of Douglas and State of Kansas, have invented a new and Improved Brake-Operati'ng Attachment, of which the following is a full, clear, and exact description.

Our invention relates to a brake-operating mechanism, theobject of the invention being to provide for an enlarged range of movement for the brake-shoe, but to provide for the application of. the power to the greatest advantage at the time when the brake-shoe is brought against the peripheral face of the wheel.

To the end'named the invention consists, essentially, of a lever and a slide mounted thereon and pivotally connected to a link, the connecting-rod, which extends to the brakeshoe, being connected to the slide, all as will be hereinafter more fully explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views. I

Figure 1 is a side view of our improved brake-operating mechanism, the parts being shown in full lines as they appear when the brake is applied,and in dotted lines at a as they appear when the brake is released, and also in dottedlines at b as the parts appear when the brake is moved to a position such that it will be out of the range of the mud thrown by the wheel. Fig. 2 is a plan view in partial section, and Fig. 3 is a cross-sectional view of the attachment.

In the drawings, 10 represents a rack, which is arranged so that it may be connected to a wagon-body, so as to be held at some distance therefrom. In the specific construction shown in the drawings the rack is made integral with a bent arm, 11, to which arm there is pivotally connected a lever, 12, and a link, 13. The rack 10 and arm 11 are in parallel planes, the arm being bolted directly to the wagon side, while the rack rests in a plane at some distance therefrom, the extending end of the rack being supported by a sleeve, 14, through which a connecting-bolt, 15, is passed.

To the lever 12 there is connectedafender,

gages the teeth 0 of the rack 10, and to the lower end of the lever there is connected a spring, 17, that bears against the inner side face of the rack, the upper end of this spring being guided by fingers 18, which are rigidly connected to the fender 9, the action of the spring being to hold the tooth 16 in engagement with the teeth 0; but when it is desired to free the lever-tooth from engagement with the rack-teeth, the lever is inoved slightly in the direction of the arrow shown in connection therewith in Fig. 3, after which the lever may be moved in the direction of the arrow shown in Fig. 1, and in order to prevent too great a movement in the direction of the arrow shown in Fig. 3 we provide the lever with an arm, 19, which overlaps the rack 10, said arm being connected to the fender 9, as shown in Fig. 3.

Upon the lever 12 there is mounted aslide, 20, to which the link 13 ispivotally connected, and to'this slide 20 there is also pivotally connected a rod, 21, the opposite end of said rod being arranged for connection with the brake, as will be readily understood. The slide is slotted, as shown, so as to ride freely over the fender.

In practice we prefer to arrange the teeth 'of the rack 10 as shown in the drawings-that is,'to provide teeth only at the forward portion of the rack, the rear portion of the rack being simply grooved to admit of the passage of the tooth 16.

In operation, as the lever 12 is moved forward from the position indicated by the dotted lines at a to the position in which the parts are shown in full lines in Fig. 1, the slide 20 is carried downward toward the fulcrum of the lever 12, and hence the effect of the power applied to said lever is increased as the lever is pushed forward, the motion of the rod 21 correspondingly decreasing. As the lever, however, is freed from engagement with the teeth c -and moved in the direction of the arrow shown in Fig. 1, the movement of the rod 21 increases as the lever is moved, as just described. To simply release the brake, the lever 12 would be moved to the position shown by dotted lines ,at a; but if it were desired to throw the brake clear from the wheel, so as to prevent it from collecting mud, the lever would be moved to the position indicated by the dotted lines at Z).

From the construction hereinbefore de scribed it- Will be seen that when the lever is adjusted to the position shown either at a or b in Fig. 1 the fender 9 will bear against the edges of the rack 10, the spring 17 at this time holding said fender firmly against the rack and in any position to which it may be adjusted, the groove formed in the rack beyond the teeth 0 being of such depth that the tooth 16 will ride freely therein.

Having thus described our invention, We claim as new and desire to secure by Letters Patent- 1. In a brake operating attachment, the combination, With a rack, of a toothed lever, a slide mounted upon the lever, a pivotallymounted link that is pivotally connected to the slide, and a rod pivotally connected to the slide and arranged for connection with a brake, substantially as described.

2. In a brake-operating attachment, the combination, with a rack the teeth of which are formed only at the forward edge, of a toothed lever arranged to engage the rack, a spring carried by the lever and arranged to bear upon the rear face of the rack-bar, a slide carried by the lever, a pivotally-mounted link that is pivotally connected to the slide, and a rod pivotally connected to the slide and arranged for connection with a brake, substantially as described.
