The principal object of the present invention is to provide a support adapted to receive and hold an object in the position. in which it is deposited upon the supportre- 5 gardless of the level of the surface of the object by which it is supported or of inequalities in the level of that surface, such as unevenness.

The support is not automatic in the full 1 sense and requires to be manually clamped.

Nevertheless it is useful in connection with molders flasks, and it is also useful for other purposes.

The invention comprises the improvements 15 to be presently described and finally claimed,

and, generally stated, it may be said to comprise in an equalizing support a group of flat strips arranged face to. face and each independently movable in response to loading,

lg means for retracting the strips when the support is unloaded, and means for clamping all the strips immovably when the support is loaded.

In the following description reference will 4 5 be made to the accompanying drawings forming part hereof and in which Figure 1 is a top or plan view.

Fig. 2 is a sectional view taken generally on the line 22 of Fig. 1.

33 of Fig. 1.

face to face and in contact and each is movable independently of the others. 2 is a frame in which the strips 1 are projectable and retractable. 3 indicates arms pivoted at 4 in the frame and having toes 5 engaging notches in the strips 1. 6 indicates springs interposed between the arms and the frame and tending to retract the strips against the abutment 7 and to lift the pads 8 on the arms 3 into position for receiving an object, the lower .surface of which is indicated by the line a-a. The pads 8 are adjustable on the arms. 9 is a clamp for clamping the strips immovably in the frame after they have been projected inward under load and for releasing the strips so that the springs may return the arms to loading position. 10 is a means for operating the clamping device. As shown Fig. 3 is a similar View taken on the line in the draiwi'ngszthestripsareinclanrped position.

- The anode iof operation of :the support may he described-as follows:

lYVith-ithe clamp :9 released, the pads are in position :to receive a load, such as a flask. Whenthezflixskisiloaded onto the pads, irregularity =or unevenness of the contracting surface ofithe flask acting through the arms 3 slides itlie stnips individually inward, and when they are. .in that position they are clamped byzthe lever 10, so that as the entire weight of the :flask comes onto the pads 8, theyarelimmovable andithus the flask rests on the supportxin the position in. which it was deposited-thereon.

- It .will be :obvious to those skilled in the artito whichz theinvention-relates that modificatiohsmay --be made in details of construction and :arrangement and matters of mere form without. departing from-the spirit of the invention which is not limited to such matters or otherwise than the'prior art and the appended. claims may require.

1. An equalizing support comprising a group of three or more -flat=strips arranged face to face and each independently movable, means for retracting said strips when the support is imloaded', individual means for each strip adapted to project the strips as the support is loaded, portions of said three or more individual means forming a firm support for the object to be supported and means for clamping all the strips when the support is loaded.

2. An equalizing support comprising a group of flat strips arranged face to face and in converging relation and each independently movable, pivotal spring pressed arms connected with the strips and adapted to receive the load, and means for clamping the strips into the position to which they have been moved by the deposition of an object on the support;

3. An equalizing support comprising in combination a group of safety strips arranged face to face and each independently movable, connected elements on opposite 2 W i r 1,875,285

of said strips and adapted to receive the load, and means for clamping said strips in contact with one another between said connected elements.

4. An equalizing support comprisingin combination aframe, a group of flat strips arranged face to face in contact and each independently movable upon said frame, a bearing on the opposite side of said group from said frame, an arm for each strip pivotally mounted in said frame and adapted to receive a load thereon and means for clampe ing said group of strips immovably between said bearing and said frame.

15 5. An equalizing support comprising in combination a frame, a group of flat strips arranged face to face in contact and each independently movable upon said frame, a bearing on the opposite side of said group from said frame, a pluralityxof arms each pivotally mounted in said frame and having engagement with one of saidstrips and adapted to receive the load thereon, springs interposed between said arms and said framefor retracting said arms when they are unloaded, and means for clamping said group of strips between said bearing and said frame immovable against one another.

6. An equalizing. support comprising in an combination. a frame, a group of flat strips arranged face to face in contact and each independentl movable upon said frame, a bearing on the'opposite side of said group from said frame, aplurality of arms each pivotally mounted in said frame and having engagement with one of said strips, a unis versal joint connection between each arm and the strip connected thereto, and means for clamping said strips between said bearing no and said frame against each other.
