WAGON-BRAKE.

Specification of Letters Patent.

Application led November 4,. 1909.

Patented July 5, 1910. Serial No. 526,316.

To all whom 'it may concern.'

Be it known that I, OLoF HILL,y a subject of the King of England, residing at Revelstoke, British Columbia, Canada, have invented certain new and useful Improvements in Vagon-Brakes, of which the following is a specification.

This invention relates to new and useful improvements in wagon brakes and is designed to provide a brake that will be automatically operated by the draft animals when the same lean back in going down a hill.

This invention contemplates the construction of a brake of this type and character which may not only be operated automatically by the animal but which may be controlled from the drivers seat.

Further, this invention provides for an adjustable brake which should the length of the body of the vehicle be altered, will adapt itself thereto, and further provides a substantial means whereby the adjustability thereof may be easily regulated.

With the above and further objects in view this invention consists in the construction, combination, and arrangement of parts all as hereinafter more fully described, specifically claimed, and illustrated in the accompanying drawings, wherein- Figure 1 is a bottom plan view of a brake applied to a wagon in accordance with my invention; Fig. 2 is a longitudinal section of a wagon showing the application of the present invention; Fig. 8 is a longitudinal section of my regulator showing the respective position of the pulleys when the same are in approximately direct alinement; Fig. 4 is a side elevation of the operating arm of said regulator; Fig. 5 is a detail longitudinal sectional view of the anti-friction slide which coperates with the regulator; Fig. 6 is a transverse section of Fig. 5 taken on the line 6 6 thereof; Fig. 7 is a perspective view of the swivel secured to the rear axle adjacent the reach; Fig. 8 is an elevation of the clamping plate thereof; Fig. 9 is a longitudinal section setting forth the detail construction of the tongue or pole of the vehicle; Fig. 10 is a transverse section of the same taken on the line 10-10 of Fig. 9.

Throughout the following detail description and on the several figures of the drawings similar parts are referred to by like reference characters.

Reference being had more particularly to the drawings A indicates in general a wagon body provided with a forward axle l and a rear axle 2 connected by the reach 3, said reach being provided with the rear hounds 4 and forward hounds 5. The brake bar 6 is mounted in the usual manner on the rear hounds 4 and is provided at each terminal with the brake shoes 7, the entire device being of the structure especially adapted to the vehicle to which the same is secured.

The swivel 7 a specifically illustrated in Figs. 7 and 8 of the appended drawings comprises a pulley 8 swiveled on the plate 9, said plate having the rearwardly extending legs or arms 10. The arms 10 are adapted to engage the rear axle, one of said arms resting over the axle thereof while the remaining arms rest longitudinally on each side of the reach on the opposite side of said axle the rearward extremities of said arms being engaged by the plate 11 the latter provided with the orifices 12 wherein the arms are retained by nuts of any adaptable nature.

Secured on the under side of the forward axle 1 is the friction slide 13 specifically set forth in Figs. 5 and 6 of the drawings. This slide comprises a pair of plates 14 and 15 between which reciprocates the bar or slide 16 having a hook 17 at its rearward extremity and an eye 18 at its forward. To lessen the friction and facilitate ease with which said slide operates a series of rollers 19 are mounted in the upper plate and are adapted to provide a bearing surface for said slide upon its operation. This antifriction slide is secured in any suitable and usual manner to the forward axle and is so constructed that it may be removed at any desired time for the repairing of the same.

The tongue 20 of the vehicle is provided along its under surface with a series of pulleys 21 and eyes 22 and has at its outer extremity the pulley or roller 23 which is so constructed that when the same is secured thereon it forms a bearing hook 24 for the yoke 26. The means whereby this pulley is secured to the terminal of the tongue comprises a series of three arms, the parallel ones 25 engaging the sides of thetongue 20 while the remaining one is secured to the under face thereof and has a hook 24 formed thereon as shown in detail in Fig. 9 of the drawings.

The regulator indicated in general asB is carried on the under face of the rear Vhounds 4 yand 'is retainedv partiallykthereby and partially by the reach 3. This regulator is set forth specifically in Figs. 1, 3, and 4, and comprises a pair of plates ,27 and 28 of peculiar configuration, having the co:

inciding approximately semi-circular slots 29-formed therein'and a series of ratchety Vteeth 30 on one side thereof. In the diametrically oppositelyA disposed corners 'of said plates, one of saidfcor'ners being adjacent lthe ratchet teeth 'and the other oppositely disposed thereof, a pair of rollers 31 are interposed. An'L-shaped arm 32 pivotally spans said regulator plates 27 and 28 and VVis formed of the plates 33 having the pulleys 34 vinterposed therebetween andV operating in the slots 29. These pulleys are arranged atV theinner terminal of the base of the L and at the bend thereof. A similar pulley 35 is carried at the opposite terminal of the arm and has secured thereon the eye 36. Interposed between the plates `33 of the .Y arm and disposed directly beneath the eye 32 of -theregulator and is adapted to pro-V 36 is a pawlv 37 retained in constant engagement with the ratchet teeth 30 by the 'spring 38. ,A centrally disposed orifice 39 is formed in the pawl to v,provide a means whereby the release line hereinafter described may be secured thereto.

y A' double pulley 40 is carried on the rear axle 2 on the side thereof adjacent the arm vide a` bearing for the releasing and con- Vtrolled lines.

In operation the animal operated line 41 is secured in the eye 18 of the antifriction slide'l3, passes throughv the pulley 21 and the eyes 22, Vand over the pulley 25 carried vwon the forward extremity of the tongue,

after. which it is secured by a loop to the snap hook `53 attached to the neck yoke 26.

y The neck yoke is removably attachedto the f the vregulator andthe arms 32 respectively after which it is secured to a chain 43, and

V any flink of which maybe fastenedto the hookV 1,7 of the slide 16. t The provision of this chain between the hooks 17 and the yoke rope 42 Lprovides a means of adjusting the length of said control line 42 and in accord- .i ance with the length of the body ofthe vehicle or" reach 3, thus supplying the feature which is very advantageous to the operation and application of the presenty invention.

` Fromthe 'foregoing description `of the opfl eration it will readily be seen that upon app'lication ofi a pull by the yoke 26 a motion in theforwarddirection will be supplied the animal controlled lines 41 and- 42 and through the instrumentality of the swivel and pulley 8 the brake bar will be moved in ysuch a manner that the shoes will engage the wheel.

The release line 44 extends from the awl around the pulley 35 at the extremity o the Varm32 and yis fastened to the release lever 45'of the compound lever indicated in general as C. The control line 46 passes from the eye 36 around the pulley 40 and lto the main body 47 of the compound levers C where it is fastened.- y

The leverC is composed of two parts 45 and 47 and the lever 45 being pivotally connected to the main body 47 and operating in the keeper 48.

In order to provide a means whereby the brake shoes may be entirely removed from engagement with the wheels, a spring 49 is interposed between the eye 50, carried on the under face of the regulator, and the similar member 51, secured to the brake bar. Thus it will be seen that when the lever 32 is released the spring will contract and disengage the brake shoes from the wheels.

The operation of the brake from the seat by the driver is asfollows: A pressure is applied to the main body 47, thus supplying a motion to the lever or L arm 32 rotating the same in such a manner that a pull will be exerted by the pulleys 34 thereof on the line 42 thus causing the brakes to be set in a manner similar to that operated by the animals. When' it is ydesigned to release the same a pressure is applied the auxiliary lever 45 raisin thel pawl and due to the tautness of theline 42 which acts as a spring the lever arm 32 returns to its normal position as illustrated in Fig. 1 of the accompanying drawings. This operation is generallyindicated in dotted lines in Fig. 1 of the drawings.

The advantages of thisy style of construction may be readily seen inasmuch as should the animal refuse to operate the brake automatically the driver may do the same, thus promoting the safety of the occupants of the vehicle and improving the general operation thereof. 'i
