cilizen of lhc Uniled hlalcs. and a residentV ol' Hlarkslmro. in the counly oll A\ddison and Stale of lrcrmonl, have. inrenled a new and Improved ll'agon-llrall'c. ol which thc following is a full, clear. and exact descriplion.

'lhis invention relates lo an aulomatic brake7 which adapted to be used in con necl'ion with carriages, wagons or the like. and isl so arranged that it may be either thrown on by hand or applied by the backingl ot thc horses connected to the tongue ol thc wagon.

.\n obieel' ol iho invention is lo provide a device which will he simple in construction, easily and quickly operated, and al the same time strong and durable.

.'\V further and imporlant object ol' the invention is lo provide means whereby the brakes may l i applied hy backing the horses, and in such a manner that there will be no strain upon lhe mcchanisu'i in traiaflingl around curves erover rough roads.

A sl'ill furlhcnohiect is lo provide means lor locking lhe l)rakcbpcrating mechanism out ol imeralion.

lhcse and lurlher objects, together with the consl'ruclion and combination of parts, will he more 'fully described hereinafter and particularly sel lorlh in the claims.

yllelercnce lo he had to i'hc accompanyinny drawings 'lor-mine a part olf lhis specilicaionr` in which similar characlcrs of rcfeb ence indicale corresponding paris in all the views, and in which- Figure l is avertical longiludimil section through a wagon havingrmy bwrake altaehed; ll'ig. 'l is a botlom plan-viewgA Eig. 3 is a verlieal l'rl'msverse section on the line 3MB of Fig. l; Fig'. Y/l is an enlarged lop plan view showing' the details ol' the longue-lockingl mechanism; Fig. 5 a vertical section on the line i3-5 ol' Fig. Lil; and Fig. G is a detail, showing the guiding` means for the con-y nection between the longue and the brake.

ReferringY more particularly to the separate parts of the. device, (3 indicates a wagon of any suilahle forni, supported at each end by trucks 7 and S, which in lurn are supported in any suitable manner, 'on the ground, by wheels l) and l0, rotatably sex cured on shafts ll and l2.

Connectingn the :front and roar lrucks 7 and S is provided a suitable wagon-reach l, which may be made adjustable by any suilable means. Secured in any well-known manner lo the lrout truck 7, there are provided converginghounds 14, to which ispivorally secured at the lront end a. suitable longue support 1.3. i

LSlidingly secured in the tongue-support 15 by any suitable means, such as brackets 16 and 17, there is provided a suitable tongue 17S. ,Secured to the under side of the tongue .Panama neuer, 1909.

V1S in any well-known manner, there is provided a suitable attaching` member 19, to which ,is lSecured a suitable flexible connection, such as a cham Q0, which passes .over a guide pulley 21, which may be of any wellknown forni, and is Secured in any suitable manner, as hy means ot' a bracket 22, to the forward truck 7.

The reach-bar ol. the wagon and the wagon proper are oiroted in any well-known man;

r Y ner lo lhe `l'ront truck i, as by means of a' king-pin 23.

lnorder to allow Yfor the pivotal motion ol the front truck relative lo the Wagon, there is provided a pair ol facing pulleys Q-L and Q5, which are pivotally secured in any well-known manner to a bracket 26, which in lurn is secured to the under side of the axle ll. The pulleys 2l and 25 are so arranged as to be lo :ated at either side of the king-pin 23, and are adapted to forni a guide .for the flexible connection 20 which passes between them.

Directly below the pulley supporting hrackct 2li, and secured thereto in any wellknown manner, there is provided a slotted `'uide d7, which adapted to slidingl'y-sef cure a connecting rod 28, to which is secured in any well-known manner the end of the llexihlo connection 20. The connecting rod Q9 is composed olf two parts overlapping at their ends and adjustable relative to each other in any well-known manner, S0 as to' ynovidc means whereby lhe'length of the rod may be. ad justed. The other end of the rod extends lo the rear ot' the wagon, and is pivotally secured in any well-known Inanucr to a lever 2f), which in turn is fulcrumed on a suitable bracket Ill), secured in any wellknown manner lo the rear truck S. The 0pposilc end ol the lever 2l) is scoured to a connecling chain ill, which is secured at its op-4 posite cud lo a l rakcbeani 32, and is adaptcd l'o operate the same. The brake-beanr 32 is pivot ally supported in any Well-known manner from the running gear of the wagon,

In order that the hrnlte may oe automat. ally rcleused, there iirofitleiii a spring' which is connected :it one end, to the ornlc-c benin 232 and nt the onpoite end to the connecting` rod and not# ,Qiuinlnneously te drain' the ineke-5in troni the wagen WheelS l0, l to return connecting rofl QS to its rearward gosition.

ln order that the. l nmy 'he applied ninnunlly, there proiided u suitable liendlever 3, which is secured in any well,-li'iown manner to n erosq shaft on which irc :it tnohefl :i l'ilunelitf ot' cranks or zinns 358, which in turn are connected by Suitable flexible connections, euch chains 3S), to the brake-benin 32.

Now, nt times itnnitic tongue-braking ineens be thrown out of' operation7 for example, when it is desired to henk the wagon up against n building;` or the like. ln order to :i :coni} )lisli this result, there in inorided :i look-engaging ineinher it), which is preferably in the foiin ot n Strip ot' nietnl heut heck on itself? to forni n lool:eii; uging toe fil, which is nlupted to enguge n loch. l2, pivoted in any wellhnown nuanner l'o :i hrnclet '43 on the retirininf"y 'nide lT.

ln order to retnin the lock 42 in engngcnient with the toe ll, there is irovided n hui-h 1li. which is piroted in :luy well-known innnner to the hrzurliet iti, und i's :u lupted to oney c :i :slide lo sslidinggly secured in :i slot in the reni) end of the lool( 42 rlhe Slide l'l-t nornmlh.' pro eed to tho limit ot its inwurd trziiei hy ineens of o Spring ri'he .hitch -f'ri if uornnilly pressed,toward the slide y4T hy inenmI ot' n spring 5l, und hns n loc-lting;v nieinher 4S, which. has :1 ridge lf? thereoiundnpted to engage n pin 5t) on the slide /lti'to hold the lock fiwith ith` renr end up, ,mul ite trout end in engugen'ient with the toe -'ll. Y

There in I iroviiled n Suitable liexihle con nection 52, which in Secured to the loch' ft2, nnd is .For the purpose of operating the lock itroni the sont of the Vehicle.

rthe operation of the device muy be readily understood from the nhove description. ll'on'ever, in order to ineke thin operation cloni', n complete cycle will loe gone through v with. lit we Sturt with the tongue. of the 55 Wagon locked to the Supporting nunnher desired that the untoiff) l5, the lool; n. Will he in engagement with the toe ,k-l, :incl thereby prevent 'the toi'igue troni Sliding relative to its supportv :ind the truck proper. When it is desired to apply the l' allies in going down hill, by ineens of the animals attached to the tongue, all that is necessary to do `te pull on the iexihle connection 59, which action 'will remove the pin 5() :troni theridge 49. Then .this has been done, the hitch 45 inunedinteiy springs toward the lock l2, und when the tension on the flexible connection 52 has been removed, the nin 51 on the slide #i6 'will slip over the camenrl'nce on the engaging ineinher which action permitted hy the spring nl?, :und the reni' cud olf the lock 42 wilt he lowered, und the front end, which was in engagement with the toe all, will he ruined, pern'iitting the tongue 1S to have n ySliding niotion rehitive to its Support l5. By the hucliwmgd pull oit the nniinnlgon the tongue 18, the iexihle connection 2O will he drown upon, :ind will in turn pull the connecting rod Q8 to its 'forward position, thereby operating the lever Q5) to throw the brakeshoe Si into engagement with the wheels l0. lYhcn the rearward pull of thevtongne lS has ceased, and the tongue starts to move in the opposite or forward direction, the spring automatically withdraws the hrake-heu1n 32 :ind at the une time forces the connecting rod l5 to its remrwz-ird position. As has "been indicated, the brake may loe also thrown ninn illy by ineens of the liniii,itever '2543, which, it desired, may also he connected to the front end 0i' the Vehicle hy suitable connectii'ig links und levers.
