BURTON W. ROBBINS, OF ST. PETERSBURG, FLORIDA.

AUTOMATIC WAGON-BRAKE.

Specification of Letters Patent.

Patented Nov. 14, 19.16.

Application filed January 14, 1916. Serial-No. 72,088.

To all whom it may concern:

Be it known that I, BURTON W. ROBBINS, a citizen of the United States, residing at St. Petersburg, in the county of Pinellas and State of Florida, have invented certain new and useful Improvements in Automatic lVagon-Brakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that type of wagon brakes, which are automatically applied by the back pressure of the horse or horses, especially when the vehicle is going down hill, and an obiect of the invention is to improve this construction of brake so that the same will be of simple construction,

cheap to manufacture, efiicient in operation and of such construction that the brake can be heldin inoperative position when it is desired to back the wagon.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, reference being had to the accompanying drawings forming a part thereof, in which:

Figure 1 is a bottom plan view of the running gear of a wagon, showing my improved brake applied thereto. Fig. '21s adetail side view of the forward end of the wagon tongue, showing an improved tip applied thereto, and showing the ordinary neck yoke" ring in moved position on the tongue. Fig. 3 is a detail side view of the forward end of the tongue and showing the position of the neck yoke ring, when the vehicle is being hacked, and Fig. at is a forward end view of the wagon tongue and tip.

Referring to the drawings in detail, the numerals l and 2 designate, respectively, the front and rear axle of the wagon and 3 the reach for connecting the front and rear axles. The rear hounds of the wagon are shown by the numerals 44.-, and extending across the inner ends of the hounds 4: and the rear end of the reach 3 is a transversely extending bar 5. Extending parallel with the reach pole 3 and on opposite sides thereof is a pair of cylindrical shaped rods 6, the rear ends of the rods having connection with eye-bolts 7 carried by the rear axle 2, and the forward ends of the rods 6 arefiattened, as shown at 8, and are extended beneath the lower side of the rod 5 and secured thereto by means of the fastening elements 9. A pair of spaced brake bars 10 are arranged in parallelism with the transversely extending bar 5 and each has its pivotal connection, at a. point approximately intermediate its ends with the forward terminal of the adjacent rod 6, by means of the pivot pin 11, and the outer end of each of the brake bars I0 is proprovided with a brake shoe 12, which is adapted, when the brake rod is moved in one direction, to'engage the adjacent wheel of the wagon.

Extending beneath the lower side of the reach pole 3, is a cable 12, which is pref erably formed of wire sections detachably connected to each other by means of snap hooks and links, the rearmost wire section being secured to the terminal of the stem of a Y-shaped member 13, the branches or sides of the Y-shaped member being extended in the direction of the brake bars 10 and secured thereto by means of connecting wires 14, as shown in Fig.1 of the drawing. Located in rear of the brake bars 10 is asecond Y-shaped member 15, the sides or branches of which have connection with the inner ends of the brake barslO by means of wires, and the said (shaped member has its stein connected,---by means of a connecting member 16, to one terminal of a horizontally disposed contractile" spring 17, the opposite end of the spring having connection 'with an eye 18 formed on the shank of a hook 19, the said hook having its bill v2O received by an eyebolt 21 secured to the inner side of the rear axle 2 of the wagon. The cable 12 is slidably extended through guides 22 carried by the lower side of the reach pole 3, and has its forward end extending through similar guides formed on the lower side of the tongue 23 of the the tongue 23, adjacent the forward end thereqf. When the brake bars 10 are in inoperative position, as shown in Fig. 1, the spring 17 will be contracted and the flexible element 12 moved rearwardly so as to hold the lever 29 at the forward end of the 7 slot inthe tongue.

In Figs. Qand 3 ofthe drawings is shown a neck yoke ring 32 of usual construction and when the wagon is moved forwardly the ring will be locatedlin rear of the depending arms 27, and has its upper side located adj acent the lever 29. When the wagon is going down a hill and backward pull is caused by the horses, the ring 32 will be moved into engagement with the lever 29 and rock the upper end thereof rearwardly, causing the lower end of the lever to move forwardly andexert a forward pull on the cable 12 so as to rock the brake bars 10 to effect engage ment between the brake shoes 12 and the adjacent rear wheels of the wagon. lVhen the brake bars 10 are rocked to efi'ectengage ment of the brake shoes with the rear, wheels, the springl? will be expanded, so that when the rearward pull is released, the spring 17 will return the operating lever and the brake bars 10 to their normal position; When it is desired toback the wagonwithout applying the brakes, the neck yoke ring 32 is moved forwardly by hand and the lower side thereof positioned against the forward sides of the arms 27, so that when rearward pull is exerted on the ring, the same will be held against rearward movement so as not to ef- 7 feet operation of the lever 29;

Copies of this patent may be obtained for Having thus described my invention what 7 I claim as new is:

l. The combination with the rear axle and the reach pole of a wagon, of a bar extending transversely of the reach pole adjacent the rear end thereof and secured thereto and arranged in spaced relation with the rear axle, a pair of rods arranged on opposite sides of the reach pole and parallel therewith, and having their rear ends connected to the axles and their forward ends extended beneath the transverse bar and secured thereto and terminally extending beyond the transverse bar, brake bars pivoted to the extended terminals of the rods, means for operating the brakebars, and means connected to the brake bars and the rear axles for returning the brake bars tonormal inoperative position.

2. In brake operating mechanism for a wagon, the combination with a wagon tongue and a bra he operating cable, and an operating lever carried by the tongue and having connection with the cable, of a U-shaped tip associated with the tongue and having the bight portion thereof located in advance of the lever and the tongue and having the sides thereof extending along the sides of the tongue, downwardly and forwardly convergin arms extending from the sides of the tip, means for connecting the arms to each other, the said arms being arranged in spaced relation with the bight portion of the tip and located in advance of the tongue, for the purpose specified. v V

In testimony whereof I aflix my signature in presence of two witnesses.
