(Cl. Z591) 4 Claims. 1
My present invention relates to a mechanism for use in the molding industry for such purposes as loosening patterns from sand molds, and the like. The principal object of this invention is the provision of a mechanism for vibrating core boxes and other parts used in the molding art which requires that certain parts be loosened from each other so that they can be separated. as a core from a core box. This can be more efiectively done when the vibrating mechanism vibrates in two planes at an angle to each other. Therefore, an object of this invention is the provision of a vibrator for causing vibrations in two planes at anangle, whether the planes be at right angles to each other or make an acute angle with relation to each other. There are in this invention such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein. My invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings and, while I have shown therein what is now regarded as the preferred embodiment of this invention, I desire the same to be understood as illustrative only and not to be interpreted in a limiting sense.
In the drawings annexed hereto and forming a part hereof,
Fig. 1 illustrates a mechanism of the type specitied in which the planes of the two units are arranged at right angles to each other;
Fig. 2 is a plan view of the structure shown in Fig. 1;
Fig. 3 represents a horizontal, medial section along the plane indicated by the line 66, Fig. 1;
and
Fig. 7 is a view similar to Fig. 1 with one of the'parts adjusted to a plane making a different angle with the attaching means.
As shown in Fig. 1, this apparatus comprises r a pair of vibrator units connected together to vibrate in planes at right angles to each other, one of the vibrator units being designated by the numeral I and the-other by the numeral 2. The primary vibrator unit I is provided with an Bil attaching lug 3 by means of which the vibrator can be attached to a part of a molding apparatus, such as a match plate or a core box. The vibrator unit I is provided with an opening for the attachment of a compressed air or steam pipe .5. Prefierably, compressed air is used for this purpose. Air entering through pipe 5 passes through the opening 6 into the space I formed in the inside Wall of the body part of the vibrator unit I. as shown most clearly in Fig. ,1. Other than this opening I, the inside face of the body Wall is cylindrical in form. The external wall of the liner or race 8 is substantially cylindrical also and fits closely the inside wall of the body part. The inner face of the liner 8 is preferably Cylindrical except for a channel ll cut therein. the edges of this channel being engaged by the ball Ill as it rolls around inside of the housing.
A cap plate II closes the open face of the vibrator unit I and is held in place by a screw or bolt I2 which extends through the body of the vibrator unit I and into the cap plate II. As shown in Fig. 3, the bolt I2 is longitudinally apertured, as indicated at I3, and a cross-opening I 4 extends from the external surface of the bolt into the opening I3. Therefore, it will be seen from Fig. 4 that, as the air enters through the pipe 5 and passes into the interior of the vibrator unit I, its direction will be substantially tangential and it will strike the ball Ill, causing it to roll around the interior of the vibrator unit I. The air will escape through the openings I 3 and I4 and enter through the openings I5 and 23 into the interior of the vibrator unit 2 where it will cause the ball I6 to roll around on the raceway II. The air escapes from the interior of the vibrator unit 2 through the opening I8, as shown in Fig. 5, surrounding the bolt I2a. From this opening I8, the air passes out through the channels 20 in the boss 2|, forming a part of the cap plate IIa. Between the boss 21 and the head of the bolt |I2a is a washer 22 which covers the grooves or channels 20.
By loosening the bolt I2, it is possible to turn the vibrator unit 2 from the position shown in Fig. 1 to that shown in Fig. 7, or any intermediate position, so that the plane of vibration of either unit can be in any direction desired. The vibrations will be simultaneous, being caused in one plane by the ball ll! and in another plane by the ball 16, the latter driven by the air escaping from the vibrator unit I into the vibrator unit 2. Hence, it will be seen that the work done by the vibrator will be doubled over what a single vibrator unit will do. It will be seen from Figs. 3 and 4 that the channel I is cut through the bottom of the groove 9' inthe race 8. It will also be seen from Fig. 3 that a groove 23 may be cut in the body of the vibrator unit 2, in the plane of the groove 9, to carry an ample supply of air from the opening [5 into the opening in the interior of the vibrator unit 2.
While I have disclosed herein what is regarded as the preferred embodiment of this invention, it will be understood that there may be departures from the specific disclosures shown without departing from the spirit of this invention or from the scope of the annexed claims.
Having now described my invention, I claim:
1. A. multiple plane vibrator comprising two air-driven vibrator units containing rollable members and connected at an angle to each other, means for delivering air under pressure to the first one of the vibrator units, and means connecting the vibrator units having a channel therethrough for the passage of air from the first vibrator unit to the second vibrator unit, the
means connecting the vibrator units connecting them rotatably with relation to each other but being capable of holding them against rotation about the axis of the connection.
2. A vibrating mechanism for use in connection with a molding machine comprising a vibrator unit having means for attachment to a part of a molding machine to cause vibration thereof in a =vertical direction, a second vibrator unit having a part thereof in common with the first vibrator 'unit, and a hollow bolt connecting the vibrator units, the hollow of the bolt opening into the interiors of the two vibrator units, said vibrator 4 rolling of the ball around the inside of the vibrator unit.
3. In vibrator mechanism for use with a molding machine, a vibrator unit having a hollow body provided with an attaching bracket and a cap plate to close an open face thereof, a second ho1- low vibrator unit having a body part and a cap plate to close an open face of the body of the second vibrator unit, the cap plate of the first vibrator unit being unitary with the body of the second vibrator unit and connected thereto by a hollow bolt, a bolt passing loosely through the cap plate of the second vibrator unit and into the body thereof, there being air vents from the bolt hole of the second cap plate venting into the atmosphere, the hollow of the first bolt placing the interiors of the two vibrator units in communication.
4. A structure as defined by claim 3 in which the second vibrator unit and the cap plate of the first vibrator unit are rotatable about the axis of the bolt connecting the parts of the first vibrator unit whereby to produce vibration of the vibrating mechanism in two planes at an angle to each other.
