United States Patent 3,412,966 VIBRATOR MOUNT Carl G. Matson, 401 E. Central Blvd., Kewanee, Ill. 61443 Filed June 9, 1967, Ser. No. 644,940 6 Claims. (Cl. 248228) ABSTRACT OF THE DISCLOSURE A vibrator mount for rigid, preferably permanent attachment to an object to be vibrated in connection with the unloading, settling, flowing, etc. of fluent, particulate etc. material, the mount being of substantial size as compared with the area of the container etc. wall to which it is attached and having one or more pairs of divergent clamp surfaces to which various types of vibrators or vibrator clamps may be attached.

Background of the invention The use of vibrators for the handling etc. of materials of the type and in the environments set forth above is of course old and well known. The problems in the general field are many, largely because of duty requirements, substantial forces involved etc., all of which lead to complications in attaching the vibrators to the object to be vibrated. The conventional railway hopper car is typical of an area in which these problems have become acute and in the past many systems of attachment have been devised and used, characterized mainly in using structural parts of the car as mounting ribs etc. for attaching the vibrators. It has been found that these parts lack strength, especially in heavy-duty operations and one attempt to solve the problem has relied upon the temporary welding of additional ribs etc. to the car. Each installation presents a special case and it becomes diflicult to match vibrators and/0r vibrator clamps with the various types of mountings. Further, the temporary weldments are often of such nature as to interfere with normal operation of the cars, especially in transit, because they present obstacles to free movement of the cars through narrow areas.

Brief summary of the invention The present invention provides an improved vibrator mount and features an attaching element in the form of an elongated bar-like rib element of V or Y section, having a central inner edge portion adapted to be welded to an object to be vibrated, a pair of symmetrically outwardly divergent longitudinal side surfaces adapted to receive comparably convergent legs or arms on a clamp means of generally C-shaped section, and a longitudinal outer central portion midway between the side surfaces adapted to be engaged by one or more screw means, the clamp means and screw means preferably being parts of a typical rotary eccentric vibrator whose axis of rotation is perpendicular to the median plane that bisects the angle between the divergent side surfaces.

3,412,966 Patented Nov. 26, 1968 Description of the preferred embodiments The numeral 10 designates a typical eccentric rotary vibrator of the type shown, for example, in the U.S. patent to Peterson No. 3,134,272, wherein an eccentric, as is known to those versed in the art, rotates about an axis A-A perpendicular to a median plane BB medially through the vibrator, This vibrator is here mounted by novel means 12, to be described in detail later, to an object to be vibrated, typically a hopper 14 as shown in FIG. 3, or to any equivalent means such as a chute, container, etc. The hopper may be an individual device for handling material or may be a discharging part of a con-' ventional railway car, in any event having a member such as a wall 16 to which the means 12 may be rigidly and permanently aflixed, as by welding at 18.

The means 12 is an elongated rigid metallic element of rib or bar-like construction having a longitudinal central inner edge or portion 20 from which a pair of integral side surfaces 22 of longitudinal extent diverge symmetrically and uniformly, preferably at angles of 45 to the median plane BB so that the included angle between two side surfaces is Additionally, the element 12 has \a central outer edge or portion 24 parallel to the inner portion 20 and thus uniformly outwardly spaced from said portion. Essentially the element has somewhat of a Y-shaped section, the inner edge or portion 20 being centered on the median plane BB and the side surfaces 22-22 being likewise divergently centered on this plane. As will be seen, the portion 20 is somewhat inwardly extended as a wing or flange from its junction with the side surfaces 22 so as to provide ample space for the weld beads at 18. The element 12 may be easily formed by any conventional rolling process or the like and therefore is quite inexpensive to produce in large quantities. As exemplified in FIG. 3, such elements may be welded to a hopper, for example, in lieu of the conventional reenforcement bars usually employed. Actually, the elements 12 may be so cheaply made and sold as to readily warrant the stripping from the structure to be vibrated of the original elements and the replacement thereof with the elements 12. If desired, the old bracing members may be left in place and the elements 12 can be added.

Since the element or elements 12 may be so inexpensively manufactured and sold, the vibrator itself may be better designed, even though the improved design results in a somewhat higher cost, because the combination provides an improvement in the overall picture, bearing in mind that the vibrator must be frequently relocated and improvements in the means whereby this may be facilitated are of significant stature. Thus the-re may be formed, preferably integrally with the vibrator housing, clamp means 26 comprising an under medial portion 28 and a pair of integral symmetrically inwardly convergent side parts 30, giving the clamp means a substantially C-shaped or dovetail section conforming to the element 12 and enabling the vibrator to be endwise or longitudinally slidably received by and removed from the element because of the cooperative dovetail rela tionship thus established.

When the vibrator is mounted on the element 12 by means of the C-shaped means 26, the medial part 28 of the means 26 overlies the outer portion 24 of the element 12 and the side parts 30 respectively match and engage the divergent side surfaces 22 of the element. The clamp means 26 is augmented by the provision of screw means, here including a pair of screws 32 threaded through the clamp means on parallel axes included in the median plane BB, the screws engaging and being tightened against the element outer portion 24. The combination of the divergent surfaces 22-30here 45 to the median plane B-B and the medially located screws 32 provides a clamping action effective in all directions as respects the forces developed by the rotating eccentric of the vibrator 10, since the divergent surfaces restrain the vibrator against upward or outward movement from the element 12 and the screws restrain against both inward and longitudinal movement of the vibrator relative to the rib, it being clear that both frictional and positive effects are achieved. Stated otherwise, the slop'mg side surfaces provide a double 90 attachment and the set screws add 90 in both vertical directions, giving a 360 lock-up against relative movement in all directions.

'In the modified form shown in FIG. 4, the element 12 has a true Y section, the vertical leg 20" providing the inner portion and the arms providing side surfaces 22', in addition to which the crotch of the Y between these arms provides a longitudinal recess or groove 24'- here V-shaped-fr receiving the screws 32, which may here have a tapered terminal end 32" to improve their relationship with the groove 0r recess 24. Again, the element 12 is welded at 18 to the wall or member 16, it being understood that the clamp means 26 as previously described may be employed.
