1 ROBERT ANLIKER, OF PIERRE, SOUTH DAKOTA.

AUTOMATIC WAGON-BRAKE.

To all whom it may concern:

Be it known that 1, ROBERT ANLIKER,

citizen of the United States, residing at Pierre, in the county of Hughes and State of South Dakota, have invented certain new and useful Improvements in Automatic NagoirBrakes, of which the following is a specification.

This invention relates to wagon brakes and refers particularly to such devices which are automatic in operation.

An object of the invention is to form a brake of this nature which is applicable to wagons of common construction without the necessity of effecting any change in the formation of the wagon, but which may be secured directly upon the running gear thereof.

Another object of this invention is to form a brake adapted for connection to the neck yoke of the draft animals, and to provide a brake which is dependent for its operation upon the movement of the draft animals.

This invention further contemplates the provision of a latch mechanism in conjunotion with the brake whereby the brake may be retained in an applied position, or may be secured against operation, this latter feature being desirable when backing the wagon.

F or a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view of the forward end of a wagon running gear having the improved brake applied thereto. Fig. 2 is a longitudinal section through the same. Fig. 3 is a detail view of the brake shaft and attachments thereto. Fig. 4 is a sectional view through the operating sleeve positioned on the forward end of the tongue. Fig. 5 is a detail View of the latch-bolt, and attachments thereto. Fig.6 is a detail view of the draw-bar and its connection to the brake-rod. Fig. 7 is a detail perspective view of the locking strap and the latch-bolt retaining plate in detached relation.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring to the drawings the numeral 10 designates an axle having wheels 11 mounted upon the opposite ends thereof in the Specification of Letters Patent.

usual manner. The axle 10 is provided with a bolster 12 which is arranged upon the upper face thereof in longitudinal alinement with the same, and serves to retain the tongue 13 across the central portion of the axle 10. The axle 10 is provided with a pair of brackets 14 which are secured adjacent the ends of the axle 10 and upon the upper face of the same. The brackets 11 are curved outwardly and upwardly at their forward ends to support a brake shaft 15 across the forward edge of the bolster 12. The shaft 15 is provided at its opposite extremities with forkarms 16 to which are secured the opposite extremities of brake-bands 17. The brake bands 17 are provided at one end with an adj usting bolt 17 a to adapt the bands 17 to hubs varying in diameter. The shaft 15 terminates at its opposite ends adjacent the inner extremities of the hubs of the wheels 11, and the shaft thereby supports the brake-bands 17 in alinement with metallic drums 18 which are secured over the inner ends of the hubs. The shaft 15 is provided with a depending arm 19 at its central portion which passes downwardly at one side of the tongue 13 and normally rests in a forwardly inclined angle to space the lower end thereof from the axle 10. A brake-rod 20 is adjustably connected at its rear end toi'the lower extremity of the arm 19 through the medium of a bolt 21 which is passed through

openings

22 and 23 which are formed in the arm 19 and rod 20 respectively, when the apertures are registered. The rod 20 extends forwardly beneath the tongue 13 and is loosely supported in such position by cleats 2O depending from the tongue 13. The forward end of the tongue 13 is provided with a sleeve 24 which is slightly reduced at its forward end and provided with a hook 25 which is curved outwardly and downwardly from the upper side of the sleeve 24. A spring-arm 26 is mounted in the forward end of the sleeve and extends outwardly therefrom to engage against the lower end of the hook 25. The sleeve 24 carries a collar 27 which is in the form of a strip of spring metal having depending ears 28 to receive the forward extremity of the brake-rod 20 and a transverse bolt 29. The bolt 29 serves the double function of adjustably securing the brake-rod 20 to the collar 27 and of clamping the collar 27 adjustably upon the sleeve 24.

The tongue 13 is provided with a longitui dinal slot 30 which extends entirely through the 'same terminating in the upper and lower faces thereof and is located at a point forwardly of the axle 10. Within the slot 30a locking strap 31 is positioned which is in the form of a strip of metal bent U-shape' and having its arms spaced apart slightly 7 as to engage the flanges 32 against the upper and .lower faces of the tongue. The lower arm of the locking strap 31 is provided with a series of teeth 34 having their shoulders formed outwardly to engage with the lower end of a latch-bolt 35 whichis carried through the flanges 32 withinthe slot 30. The latch-bolt 35 isprOV-ided'With a spring 36 having its upper end -engaglng against the under side of the upper arm of the locking strap 31, while its-lower end is held against a pin 37 secured through the latch-bolt 35 adjacent its lower end. The upper arm of the locking strap 31 is longitudinally slotted to admit of the reciprocation of the locking strap between the flanges 32 and about the latch-bolt 35. The upper flange 32 issuitably apertured to receive the bolt 35 therethrough and carries a cam 38 upon its'upper'face and about the aperture tocoperate with a pin 39 to retract the bolt 35 upon the teeth 34. The pin 39'is secured through the upper end of thelatchbolt 35 and rides over the inclined face of the cam; An angular head 40 'is formed upon the upper end of the bolt 35 to receive thereover a correspondinglyformed socket 41 which is carried by a hand-wheel 42. Through the forward end of the slot 30 a draw-bolt '43 is positioned which extends downwardly through the forward ends of thelocking strap 31 and is connected to the brake-rod 20 through the medium of a clamp 44. The upper arm of the locking strap 31 carries a spaced arm 45 beneath which is pivotally disposed a whiffletree 46 for drawing the vehicle. comprises a strip of metal which'is overlapped upon itself and looped at one end to bind about the brake-rod, the free ends of the clamp being secured together through the medium of a bolt 47. .The draw-bolt 43 is passed downwardly through the free ends of the clamp 44 and is secured loosely in such position through the medium of a nut 48.

In the use of the brake the neck yokes of the animals are secured to the hook 25, whereupon the backward movement of'the draft animals effects the sliding of the sleeve24 backwardly overthe forward end of the tongue 13. This movement is com- The 1' clamp 44 arm 19 to rotate the shaft 14 and to turn the fork-arms 16. The movement of the fork-arm 16 contracts the bands 17 about the metallic drums 18 of the wheels 11, whereby the braking action .is eflected. When the brake is thus applied the brake-rod 2O forces the draw-bolt 43 into a backward position as the same, is connected to the rod 20 by a clamp 44. The locking strap 31 is likewise moved backwardly in the slot 30 under the action of the draw-bolt 43. Should the pin 39 be released from the cam 38 the latchbolt 35 rides over the inclined portions of the teeth 34 and is depressed into the throats of the teeth to engage against the forward shoulders thereof and lock the strap 31 from forward movement. The brake is thus antomatically locked and can only be released by raising the latch-bolt 35 from engage ment with the teeth 34. To release the brake the socket41 is positioned over the angular head 40 and the hand wheel 42 is rotated to engage the pin 39 upon the cam 38. The bolt 35 is raised during this action and the locking strap 31 is permitted to move forwardly. Should it be desired to back the wagon without applying the brake thereto. the'pin 39 is disengaged from the cam 38, and the draft animals are moved forwardly and suddenly to draw the locking strap 31 forwardly through the slot 30 to bring the shoulder of the rear tooth 49 beneath the latch-bolt 35. The latch-bolt 35 now snaps into position under the action of thespring 36 and prevents the backward movement of the strap 31. As the wagon is now moved backwardly, the brake-rod 20 is held from movement and can only be released upon the raising of the latch-bolt 35.
