Gegenstand der Erfindung ist eine Dezimal-Brückenwage, deren Brücke im unbelasteten' Zustande, ,sowie bei jeder unter einer bestimmten Größe verbleibenden Belastung innerhalb eines sie umschließenden Rahmens unschwingbar und unverschiebbar gehalten ist und erst nach Belastung über ein bestimmtes Mindestgewicht hinaus für die Dauer der Wirkung desselben aus der Sperre gelöstThe subject of the invention is a decimal bridge wagon, the bridge of which in the unloaded ' Conditions, as well as with any load remaining below a certain size is held immovable and immovable within a frame surrounding it and only after loading beyond a certain minimum weight for the duration of the Effect of the same released from the lock

ίο und in Wägestellung belassen wird. Durch diese Einrichtung soll unter Ausschluß sonstiger Festlegevorrichtungen das Schwanken und Spielen der Brücke während des Transportes der unbelasteten Wage und während des Aufbringens und der Entnahme der Last von derselben, sowie außerdem deren Verwendung zum Abwiegen von leichten Gegenständen solcher Art verhindert werden, für welche eine Dezimalwage ungeeignet erscheint und deren Gewicht zweckmäßiger auf gewöhnlichen Tafel- oder Schalenwagen festzustellen ist. ίο and is left in the weighing position. By this device is intended to prevent swaying to the exclusion of other fixing devices and playing the bridge while the unloaded car is being transported and during the application and removal of the load from the same, as well as their use for weighing light objects of the kind for which a decimal scale appears unsuitable and the weight of which can be determined more appropriately on standard table or tray wagons.

Auf der Zeichnung ist diese Brückenwage durch Fig. 1 im Längsschnitt im unbelasteten Zustande und durch Fig. 2 in Seitenansicht im belasteten Zustande zur Darstellung gebracht. In the drawing, this bridge car is through Fig. 1 in longitudinal section in the unloaded States and shown by FIG. 2 in a side view in the loaded state.

Sie ist bezüglich ihrer Hebelanordnungen und der Gewichtsschale in bekannter Weise gebildet, indes mit einem gegen das gebräuchliche Maß erhöhten, allseitig geschlossenen und nur oben offenen Aufnahmekasten α für die Brücke ausgestattet. Diese letztere stellt sich in diesem Falle als ein an der hinteren Schmalseite offener und mit einem verschiebbaren Deckel c versehener Kasten b dar, dessen vordere Schmalwand b^[ nach oben hin verlängert ist, während die Deckelplatte c auf ihrem dieser verlängerten Wand b¹ zuliegenden Ende eine aufrecht stehende Platte c¹ trägt. Zur Erleichterung der Längsverschiebung der mit Leisten in Innennuten Z>² der Kastenseitenwände eingreifenden und dadurch zwangläufig geführten Deckelplatte c sind die an der unteren Seite der letzteren befindliehen Räder d bestimmt, welche auf Schienen e der Bodenplatte des Kastens b rollen. Außer diesen Schienen e trägt diese Bodenplatte noch eine querliegende Achse i, welche mit zwei in bestimmtem Abstand voneinander befindlichen doppelarmigen Hebeln k, sowie mit einem zwischen diesen Hebeln liegenden Zahnsegmentstück / ausgestattet ist, das in eine gegen die Unterseite der Deckelplatte c befestigte Zahnstange η eingreift. An dem Vorderende jedes Hebels k ist eine Lamelle h angelenkt, welche den betreffenden Hebel mit dem Vorderende einer kräftigen Eisenplatte f verbindet, die in der Breite der Deckelplatte c um eine von dieser getragene Achse g schwingt und in Tiefstellung mit ihrer ganzen unteren Fläche zur Auflagerung auf ihre Tragplatte kommt. Auf dem hinteren Schenkel des doppelarmigen Hebels k befindet sich ein längsverschiebbares und in jeder Lage feststellbares Gegengewicht m. Die hintere Schmalseite der Deckelplatte c ist auf ihrer ganzen Länge oder nur auf dem mittleren Teil derselben von einem Metallstab q bedeckt, dessen Vorderseite auf seiner ganzenWith regard to its lever arrangements and the weight shell, it is formed in a known manner, while it is equipped with a receiving box α for the bridge, which is raised against the usual level, closed on all sides and only open at the top. This latter is in this case as an open on the rear narrow side and provided with a sliding cover c box b , the front narrow wall b ^[is extended upwards, while the cover plate c on its end facing this extended wall b ¹ upright plate c ¹ carries. To facilitate the longitudinal displacement of the cover plate c ^{, which engages with strips in internal grooves Z> 2 of} the box side walls and is therefore inevitably guided , the wheels d located on the lower side of the latter are intended, which roll on rails e of the base plate of the box b. In addition to these rails e , this base plate also carries a transverse axis i, which is equipped with two double-armed levers k located at a certain distance from one another and with a toothed segment piece / located between these levers, which engages in a rack η fastened against the underside of the cover plate c . At the front end of each lever k a lamella h is hinged, which connects the relevant lever with the front end of a sturdy iron plate f , which swings in the width of the cover plate c about an axis g supported by this and in the low position with its entire lower surface for support comes on their support plate. On the rear leg of the double-armed lever k is a longitudinally displaceable and lockable in any position counterweight m. The rear narrow side of the cover plate is c over its entire length or only in the middle part thereof of a metal rod q covers the front side throughout on its

Claims

Width is notched like a saw blade. A bar q1 of the same shape and also horizontally running notches is fastened opposite the former at the same height to the upper end of the rear wall of the support box α, which is equipped with a longitudinal strip a2 on the inside. On the inside of the support stand al of the upper balance beam held by the box a, a metal plate u is fastened at the level of the bridge b, opposite of which supports a second plate w with as little space as possible, which is in some way connected to the bridge b . When the scales are unloaded, under the action of the counterweight m, which is then in the lower position, the plate f swinging about axis g has swung down to a certain extent from its base c and at the same time the latter is pushed back by the toothed segment piece / on its path between the longitudinal grooves b2 so far that the prongs and notches of the rod q participating in the displacement have been inserted into those of the immovable rod ql and at the same time the plates w and u are pressed against one another. If the bridge is then loaded according to regulations by pushing the object to be weighed onto it from behind, the fixing of the bridge to its frame α caused by the toothed bars and the smooth plates will still be maintained until with increasing distance of the load from the swing axis g of the plate f the effect of the counterweight m finally overcome and with the consequent lowering of the plate f and the swinging of the weight m under the action of the oscillating tooth segment I on the rack η the pushing out of the cover plate c the inhibition ql and its further advance until it rests its base plate c1 against the front wall b1 of the bridge. The balance is then in an operational state, and the weighing can be carried out, after its completion with the pushing back of the weighed load beyond a certain point of the plate f and the then re-occurring effect of the counterweight m again the fixing of the bridge, and takes place while the load remains on the rear half and the resulting balance between load and weight. This scale is mainly intended for weighing large quantities of objects of approximately the same weight, of filled sacks, bins or boxes, or in the event that the contents of such containers are to be brought to a certain weight by refilling or removal, even for such weighings during which the load on the weight tray remains constant. To precisely determine the number of weighings, a counter s is then attached to one point of the non-displaceable part of the bridge - expediently on top of the front wall b1 of the same - the switch lever s1 of which is connected to a tie rod t hinged to the base plate c1 of the displaceable cover plate c and whose row of digits is intended to indicate the number of displacements of the two plates b1, c1 against each other corresponding to the number of weighings. Godfather nt-A ν Proverbs:

1. bridge car, characterized in that under the increasing action the load on a movement mechanism when the bridge is postponed when a counterweight is finally overcome by this load, a movement of the mechanism takes place through which such a displacement of the support plate causes the load in the horizontal direction becomes that the unloaded and under a certain minimum weight loaded Bridge clamping of the bridge in its mounting frame brought about by the effect of the counterweight lifted and the scales made operational.

2. Embodiment of the bridge wagon according to claim 1, characterized by a horizontally displaceable cover plate (c) of the box-shaped bridge (b) mounted in a closed frame (a ) and a swingable flap (J) supported on this cover plate (c ), which is connected by support plates (h) to a double-armed weight lever (k) carried by the non-displaceable part of the bridge. and if the load on the flap remains below a certain minimum

(J) remains swung down from its support plate under the action of the weight lever (k) , but is brought to rest on it when the load exceeds a certain level and the swinging movement of the lever (It) caused by its change in position causes an on the axis (i ) the same located tooth segment piece (I) rotates in such a way that it goes through

Engagement in a rack (s ) firmly connected to the cover plate (c) causes the displacement of this plate and the release of the same from the fixed connection with the support frame (α) of the bridge, which has been maintained up to now by the action of the weight lever (k).

3. A bridge wagon according to claim 1, characterized in that a counter fs) is incremented to indicate the number of weighings that have taken place by the horizontal displacement of the receiving plate (c) of the load caused by each weighing.
