PATENT AUSTIN MCGLATHERY, OF NORMAN, OKLAHOMA TERRITORY.

AUTOMATIC BRAKE.

SPECIFICATION forming part of Letters Patent No. 598,000, dated January 25, 1898.

Application filed March 18, 1897. fierial No. 628,113. (No model.)

To all whom it may concern:

Be it known that I, Aus'rm MCGLATHERY, a citizen of the United States, residing at Norman, in the county of Cleveland and Ten ritory of Cklahoma, have invented certain new and useful Improvements in Automatic 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 automatic brakes for wagons and other vehicles, the object being to provide, in connection with-a suitable brake, means whereby the brake-shoes may be automatically set in descending grades, means also being provided whereby the brakes may be locked in engagement with the wheels.

The detailed objects and advantagesof the invention will appear in the course of the subjoined description.

The invention consists in a brake embodying certain novel features and details of construction and relative disposition of parts, as hereinafter fully described, illustratedin the drawings, and incorporated in the claims here- In the accompanying drawings, Figure 1 is a reverse perspective view showing a wagonbody and the improved brake mechanism applied thereto. Fig. 2 is a perspective view of the front end of the body, showing also a portion of the tongue,.the whiffletree, and the means for locking said whiffletree either in its rearward or forward position.

Similar numerals of reference designate corresponding parts in the figures of the drawings.

For the purpose of illustrating the present improvements I have shown the same as applied to a wagon-body, although it will be apparent as the description proceeds that said improvements may be applied to any vehicle.

Referring to the drawings, 1 designates an ordinary wagon body, and 2 a transverse brake-beam carrying brake-shoes at its ends adapted to be brought into contact with the wheels, the brake beam being shown as mounted adjacent to its ends in longitudinally-elon gated hangers 3, whichpermit said brake-beam to move transversely or in a direction lengthwise of the wagonbody.

a designates a lever which is fulcrumed at 5 intermediate its ends on the bottom of the wagon-body, the fulcrum 5 being at one side of the center of the Wagon-body. Connected pivotally to said lever 4, at the point 6, which is approximately in the longitudinal center of the wagon-bod y, are the convergent ends of a pair of braces 7, which connect at their opposite ends to the brake-beam 2, whereby as the lever 4 is vibrated the brake-beam 2 is moved so as to throw the brake-shoes into and out of engagement with the wheels.

Connected to one end of the lever 4 (the shorter end) is a spring 8. This spring is shown to be'of spiral form and has passing therethrough a pair of rods or connections 9 and 10, the connection 9 being secured at one end to the end of the lever 4 and at its opposite end to the farther extremity of the coiled spring 8. The connection 10 is attached at one end to the opposite end of the coiled spring 8 and at its other end to a chain 11 or other flexible connection, which is in turn secured at its opposite end to a stud 12 or other projection on the side of the wagon-body. The spring is preferably located at one side of the wagon and serves to vibrate the lever 4 in a direction which will move the brakelever and the brake-shoes toward the wheels. Connected to the opposite end of the lever 4 is a chain, rope, or cable or other suitable flexible connection 13. This connection extends forward and passes under the bolster of the wagon and connects at its forward end to an eye 14 on the whifi'letree 15, the eye 1% being located, preferably, centrally of the whiffletree and the whiffietree being movable forward and backward, whereby the connection 13 may be drawn upon for releasing the brake-shoes.

16 designates an inverted-U-shaped bracket which is secured to the upper side of the wagon-tongue 17 and which, in addition to its function as a bracket, also constitutes a rear stop for limiting the backward movement of the whiffletree.

18 designates a guide or keeper consisting of a rod superposed above the tongue and having its forward end turned downward and secured to the tongue, whileitsmear-endis r secured to the upper horizontal or connectin port isn'ltiof thebracket'lfi. The Whiflietre is adapted to siide hack and forth withins'aidi keeper and :is provided with an eye erstaple 2O,which embraces the horizontal 'portionfl of thekeeper, thus preventing endwi-semo've 1 mentof thewhiffietree, while permittingsaid; 1 1 whiiiietreeto slide in a' forwardzor backward 1 direction. I r 22 designatesalatchwh his pivotallyconnest-ed to the bracket 16,

When the lever 31 is vibrated in the opposite direction, the connection 30 will elevate the leverarm of the latch and force the free end of the latch downward, so as to engage either in front of or in rear of the whiffietree.

From the foregoing description it will be seen that when the latch 22 is lifted the whiffletree 15 is capable of moving back and forth, so that when draft is removed from the whiffletree the brakes will be automatically applied. In case the animals should attempt to run off the free end of the latch may be thrown downward in front of the whiflletree, thus preventing the animals from moving the whiffletree forward and releasing the brakes. In ascending inclines the latch may be thrown downward behind the whiflietree, so as to prevent said whiffletree from being drawn backward, which would result in applying the brakes. The mechanism described is extremely simple and is under the immediate and full control of the driver.

It will of course be understood that the brake and the several parts thereof hereinbefore described are susceptible of changes in the form, proportion, and minor details of i eonstru ction r is fulcrum ed mechanismyof a guide'for; said whifd'etree, a 3 front of the wagonbody, sorthat the driver.
