To aZZ whom, it may concern:

Be it known that I, ELIAs B. Rose, a citizen of the United States, residing at Electric, in the county of Park and State of Montana, have invented certain new and useful Improvements in VVagon-Brakes, of which the following is a specification.

This invention consists of an improved form of vehicle-brake, the brake mechanism being of such a nature as to automatically operate upon the back pressure on the tongue connected therewith. The brake mechanism is devised with a view to obtaining the greatest amount of brake action inretarding the progress of the vehicle, the invention embodying a special form of tongue whereby the brake devices are actuated automatically.

The invention further includes meanswhereby the brake may be operated byhand, which may be desirable under certain conditions of service. I

For a full description of the invention and the merits thereof and also to acquireaknowledge ofthe details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view of the running-gear of a wagon, showing the practical application of the invention thereto. Fig. 2 is a vertical longitudinal sectional view of the invention, the tongue of the wagon being extended and the brake set. Fig. 3 is a partial sectional view longitudinally of the tongue, the sections of the tongue being shown in the positions assumed thereby when the brake mechanism is not set. Fig. 4 is a side elevation of thefrontof the wagon, showing a modified arrangement of operating-rope permitting operation of the brake mechanism by hand.

- Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. 7

1n the drawings the construction of the ru nning-gear illustrated is of a conventional type, and it will be understood that the same may be varied according to the particular style of vehicle to which the brake mechanism may be applied.

The numeral 1 designates the front and rear axletrees, which carry the ground-wheels and which are connected, as customary, by means of a reach 2. Hounds 3 and 4 extend from the rear and front axles, respectively, the hounds 4 being connected with a tongue 5 at the rear extremity of the latter. The preferred form of brake means used in connection with the invention consists of a transverse bar 6, which is substantially attached to the rear end portion of the reach 2 and the which for the purposes of this description will be described as relatively stationary and relatively movable sections, respectively. The section 5 of the tongue is connected with the hounds 4, and attached to the section 5 is a sleeve or similar member 10, through which the section 5 of the tongue is arranged to move. The section 5 is quite a little longer than the section 5, preferably, and secured to the rear extremity of said section 5 is the doubletree 11 or other equivalent draft means. The longitudinal movement of the section 5 upon the section 5 ofthe tongue is limited by a connection 12, secured at one end to the rear end portion of the section 5 and attached at the opposite end' to the doubletree 11 aforesaid. Thus the section 5 of the tongue, though adapted for slidable movement upon the section 5, is so connected therewith as to place all draft upon the section 5? in a manner which will be obvious. The section 5 is operably connected with the brakebeam 7 by means of a flexible connection 13, consisting of a rope, cable, or the like, said connection 13 being attached at its rear extremity to a lever 14:, pivoted at its upper end. to the reach 2 in advance of the brakebeam 7. The lever 14L is connected at a point between its ends by means of a rod 15 with the lower extremity of a second lever 16, pivoted to the reach 2 in rear of the beam 7. A spring or like elastic connection 17 is attached at one end to the rear axle 3 and at its opposite end to the lower extremity of the lever 16, which is connected with the rod 15. The lever 16 is pivoted at a point between its ends, as shown at 18, to a bracket 19, projecting from the rear axletree, the upper extremity of the lever 16 being connected by a link-bar with the brake-beam 7 It will thus be noted that when the flexible connection 13 is pulled upon the'levers 14: and 16 will be actuated against the tension of the spring 17 and the beam? will be pulled rearwardly and cause the shoes 9 to engage the ground-wheels, the brake being set in this manner. The connection 13 is actuated by the movable section 5 of the tongue 5, and for this purpose said flexible connection passes upwardly through an opening 21 in the section 5 of the tongue near the rear end portion of the latter and thence upwardly through a second opening 22 in the section 5 A ring 23 at the forward extremity of the connection 13 prevents said connection from being pulled through theopening 22 of the section 5 when tension is placed upon the connection 13 by movement of the section 5 with relation to the section 5. The connection 13 passes about pulleys 24:, located adjacent the openings 21 and 22, so as to reduce all friction between the connection and the parts by which it is actuated to a minimum. 1

The operation of the connection 13 by the tongue is as follows: As the vehicle is moving forwardly the draft upon the tongue causes the section 5 thereof to move to the forward limit of its movement determined by the length of the connection 12. When the tongue-section 5 is at the forward limit of its movement,

the openings 21 and 22 may be, and are, pref:

erably, in the construction shown, in vertical alinement, a certain amount of slack being caused in the length of the connection 13. In stopping the vehicle the back pressure exerted upon the section 5 by the draft-animals will cause this section to move upon the section 5, sliding freely thereon through the sleeve 10 and reinforcing-bands 25, which pass about the tongue-sections in front of the sleeve. The rearward movement of the section 5 relative to the section 5 deflects or takes up the slack in the connection 13 to such an extent that said connection is pulled upon with great force, actuating the brake-levers 1 1 and 16 and applying the brake-shoes to the groundwheels in a manner readily apparent. The movement of the section 5 of the tongue is of course entirely automatic in stopping the vehicle, and the peculiar arrangement of the tongue-sections and relative movement thereof effects the necessary actuation of the connection 13 to apply the brake mechanism with great power. It is contemplated that the connection 13 may be connected with any suitable form of brake devices, those illustrated being preferably utilized.

When it is desired to back the vehicle in order that the brake mechanism may not be operated, special lock means are utilized to prevent the tongue-section 5 from moving rearwardly, such means comprising, essentially, a pivoted lock-dog 26, which is pivoted between the sides of a U-shaped bracket 27 which extends upwardly from the sleeve 10.

The dog 26 is arranged to be actuated by means of a rope or similar connection 28,which is provided with a hook 29, adapted to engage a ring 30 in the end of a short cord 31, di-

rect] y connected with the upper portion of the dog 26. The dog 26 is adapted to engage in a plurality of longitudinal recesses 32, formed in the upper side of the section 5' of the tongue adjacent the sleeve 10. The dog 26 is sufliciently heavy to gravitate rearwardly when the rope 28 is pulled upon, so as to rest upon the sleeve 10 in rear of the member 27. A pull upon the rope 28 will raise the dog and throw the same forwardly, so as to engage the same in a recess 32 to positively prevent rearward movement ofthe tongue-section 5 upon the section 5 in backing. The said dog is advantageous to lock the tongue-section 5 after the brake has been set and the vehicle is not moving.-

Under some conditions it is desirable to operate the brake mechanism independently of the tongue or by hand, and in this instance the hook 29 of the rope 28 will be hooked into the ring 23 of the connection 13, the rope being passed through the ring 30 of the cord 31, connected with the dog 26. It will be noted that if the wagon-box of the vehicle is in po" sition thereon the rope 28 may be connected with a suitable operating-lever. The rope 28 may be actuated, however, in any suitable manner. WVhen the rope 28 is connected with the connection 13, as above described, it will be apparent that the driver of the vehicle by pulling upon said rope 28 can actuate the connection 13 to set the brakes entirely independent of the tongue 5, said connection being pulled through the openings 21 and 22 of the tongue-sections when the brake is being operated independently thereof. It will be TOC clear that the dog 26 is operable by the rope 28 when the brake is operated independently of the tongue, as well as when it is operated by means of the tongue.

It will be understood, of course, that the brake works automatically in descending grades, as the draft-animals hold back, forcing the movable section of the tongue rearward] y and causing the brake-shoes to contact with the ground-wheels in an obvious manner. WVhen the vehicle reaches the level grade, the back pressure upon the movable section is relieved as the animals pull forwardly on the doubletrees and the brake-shoes are thrown away from the wheels.
