TIPPING GAR.

Application led May 9, 1927, Serial No. 190,062, andi nrermanyYV anuary 9, 1926i This invention relates to a hydraulic tipping device for the loading floor or the car body of three-way tipping cars, especially freight motor-cars, and the gist of the inventi'on resides therein that, apart from the controlling device proper, by which the: source of power, viz, liquid under pressure, is controlled, a. separate device is provided by which the looking, as well as the releasing of the turning joints for said floor orv body is regulated.

Therev have been distinguished up to now, as is known, twol fundamentally different types ofl devices for the purpose in view, viz:

First, that type in which, prior to starting the control-gear of the: source of power, a number of the turning joints are opened mechanically and the others are closed Ine-- chanically by manual actuation, and

Second, that typeV in which Vthe turni-ng joints are acted on by the source of power itself, i. e. by the liquid under pressure, by the intermediary of a separate device, inf` such a way, that some of` said joints are opened automatically by said liquid.

In both cases the turning joints are ,opened by means of a separate device, and in the first of said cases. also the closing is', under circumstances, effected by means of that device.

New, in contradistinction thereto the. present invention consists therein that opening the turning joints for the loading floor or the car body is effected indirectly by thisfloor or' body itself without a separatey device and that a separate gear movementy is: provided by which the closing heads for the turning joints or `bearings of the said floor or body are released or locked in dez pendency ofthe position of the control-gear A for thev source of power'.V

The invention is illustrated diagrammati cally and way of example in the accompanying drawing in which Figure 1fV is a planl of the control-gear and the separate gear" movement, together with the turning bearings for the loadingfloor or car body, the parts being shownl in the 'position in which the floor or body canbe tipped to the left Figures 21,V 3 and t are sections taken on, they lines A+B, C-D and E-F respectively of Fig. 1', and Figure 5 is a sectional view of modified constructional detail.

The device consists of a shaft 1 which is provided. with a grip 2 and a pinion 3, this latter-:meshing with teethy 4e provided on: a ledge 51- carriedv by vone of the' longitudinal girders; of theframe of the carxand' being' shi'ftable at .or in the respective girder. A similar ledge 6 ifs arranged practically in the' same I-nannerl ator in the other longitudinal girder ofthe frame and isy connecte-d with the; ledge 5 in a positive' manner by double-armed levers' -7 and. 8, the thus coupled members forming a sor-called cineL maticchain. Said levers are supported at their centerportions 9 and 10 at the frame, and their slotted ends'are engaged by

pinsL

11,12, liand 14 projecting from the ledges 5` and 6. Inconsequence thereof of every position of one ledge a definrte position corH responds for the other ledge'.k x

order-tof obviate any dead play between they members ofl the cinematic chain, each ofl asy shown'. in Fig. 2, the opposite endsof the partsl being, shaped as shown and. connected with each other by a tension spring 58.A The otherends' of the ledge parts are provided with 'holes 15: and'. slot-like hol-eextensions 16, and the diameter of saidl holes is such' tl-iat'.heads-.1?,` 18,319 and 2.0 providedy at` the ends of

rods

21, 22, 23 and 24 can 'enter intol and through theinf.. These rods are con-- nected attheir' othert endsl with

locking heads

25, 26, 27 and 28` which Vcov-operate with the .the ledges. 5? and 6 may comprise two parts,

turn-ing bearingsjfor the leading floor'i'nV the rn'anner hereinafter described. The rods 2-1-24e are;` supported ini the

axlesl

59,60, 61 and 62. pertaining to said bearings. y

In: the: constructional form: shown in Figs. it-4: the locking heads. are yrigidly connected with the outer. ends' ofthe rods 2'1-'24:, but

the modificationshown Fig. V5 they are movablyconneeted. with said: rods, as well as with. the axles' mentioned. j

Y The said vheadsk have oblique facesf'or noselile projections 29?, 30;, 31 and 32 and are pressed by'springsiO against pivots 41./ The length of the slots 16 is such :that thelecliges 5 and 6 can` be shifted longitudi-y nally and receive irri-said slots therods 2'1--241 whereby theset lattery can' be locked' in certain positions due toy thfefactA that the heads v 17T-20F cannotv passthrough said slots.v

The control device carried'by the. bracket 335,; 1,l consists; of a hand-lever 34,111 sha-ft 35de which this lever is: affixed, and a craanlrarrn'36` also secured to'said shaft'.

Theicrarrk-arm ifs'connected with a projection 38; which can pass through recesses 39 ofy the led 5 only when this ledge is in certain de nite positions, whereas the rod 37 is checked in all other positions vof the ledge l5 whereby the control gear is locked. The

attendant can, therefore., actuate this gear only after having shifted the ledge 5 into a certain definite position.

The rod 37 extends over both ledges (5 and 6) to another crankarm 36Et connected with said rod, as well as with another handlever 34* by which the rod 37 can be actuated Valso from the other side of the car. The rod 37 is, furthermore, provided with a pin 42 engaging a slotted arm of abellcrank lever 43 rotatable on a bolt 44 attached to the frame of thecar. The other arm of the bell-crank lever is connected with one end of a rod 45, the other end of which is coupled ywith the adjusting-device of the control member 46 housed in the casing ot the lifting device. The rod, or control-rod, 45* extends through the liquid receptacle of the pump in such a manner that it has a certain free play and can follow freely the lateral movements of the lifting device.`

As long as the control lever is not adjusted for lowering, or asV long as the tipping I has not proceeded so farthat the

locking heads

25, 26, 27 and 28 have been moved into the locking position by means of the springs 40, the position of the members for the time being cannot be changed. VThis might be possible, however. during the lowering of the loading oor,but means are provided for preventing any undesired re-adjustment. .This means consistsof recesses 56 (Fig. 1) -in the ledge 6,: a projection 53 y adopted to kengage any one of said recesses,

and a spring 54, Fig. 3, holding said projectionr in the respective recess as long as the loadingfloor is not supported in any of its tipping positions. The projection 53 i is inserted into asliding bolt 55 subjected to the pressure of a spring 54 which' tends Vto hold the bolt continually in Araised posi# tion. As long as the loading floor, or the car-body respectively, restsY upon all supporting points the bolt is `kept continually depressed counter to the pressure of the spring 54, in consequence ywhereof the projection 53 does not engage any of the recesses 56. But when the loading floor or the Y car body is tipped, the bolt 55V will` be lifted l no and without any damage to the Vcontrol gear, as the spring 48 will be compressed in that case.

' The locking heads 25-28 operateas follows:

In lthe construction according to Figs. 1 4, the locking heads 25-28 are rigidly secured to the outer ends of rods 21-24. They are under the influence of Asprings 4() as shown in Fig. 4. These springs, at one end, abut against a shoulder of the rotatable aXle, as for instance, the rotary bearing arms or axles 59-62. rlhe other end of the springs bear Vagainst shoulders of the locking heads and exert pressure in order that the locking heads may be forced in the locking position in which they lie against the pivots 41 when the body of the car is in the lowest position and they grip the lower angular surfaces. The other inner end of the rods 21H24 'terminate in rigid heads 17-20,`shown in Figs. 1 and 4. VAt the point where the heads 17-2O are yprovided on the rods 21e-24, ledges 5 and 6 are arranged, having perforations 15 therein which are of such a size that the heads la7-20 can enter therein when such perforations lie directly in front thereof. The perforations themselves are connected to `each other by means of slots 16 which also project beyond the sides of the perforations. The length of the rods 21--24 are so arranged that their heads 17-20 project into the ledges 5 andy 6 when the body is set loo down whereby the rods 21-24 will project through the slots 16. The slots 16 are so wide that Vthe ledges 5 and 6 can be moved over rods 21-424. It is, therefore, possible to move the ledges 5 and 6 with the aid of the parts'l, 2 and 3 and thus secure a definite connection. Thereby the ledges are so adjusted that, las vshown in Figs. 1 and 2,

two rod heads 19 and 20 will not lie in front of their perforations 15 of the ledge 5 but will be at the side thereof in front of the slot, while the rod heads 17 and 18 directly opposite will bein front of their respective f perforations 15 of the `ledge 6. Ifnow the control is placed in operation, that is, the hydraulic tipping arrangement is seft to lift -the body, then the body of the car will be raised and the pivots 41 will vabut against thc angular surfaces of the locking heads 25-28. .Since the

heads

19 and 20 of the

rods

23 and 24, to which the locking heads 27 and 28 are arranged, are secured by means ofthe ledge 5, the locking heads 27 and 28 cannotmove away but must remain in their Y separate change-position device comprisingk positions. The pivots 41 of the opposite locking heads 25 and 26 operate by means of the wedging action of the l(ngular surfaces so that the locking heads will operate outwardly against the force of the springs since the

heads

17 and 18 of rods Q1 and 22 can project into the perforations 15 of the ledge 6. The body or" the car will thereiore tip to the left. in Fig. 1, the locking heads are shown in open position whereby the

heads

17 and 18, as illustrated, lie in the perforations 15 of the ledge 6. As soon as the pivots 41 have gripped with the angular surfaces of the locking heads 25 and 26, they Will set themselves again in a closing position due to the operation of the spring 40. In lowering the car, the various operations are repeated in reverse manner. The pivots 41 will lie against the upper angular surfaces of the locking heads 25 and 26 whereby they will move themselves outwardly against the force of the springs 40 and as soon as the pivots 41 lie in their bearing, the locking heads will move inwardly automatically under the influence of the springs 40.

I claim: e

1. A three-way hydraulic tipping device comprising a supporting frame having bearings and body latches; a body having com bined pivot and bearing members; springactuated locking heads forming parts of said bearings and each having two oblique faces adapted to cause automatic opening of the heads when the body is lifted or lowered, a
