Application August 24, 1956, Serial No. 606,029

2 Claims. (Cl. 248-157) My invention relates to leveling devices and is of particular utility where several elements are adapted to be mounted at a given height.

My invention contemplates a movable structure which has a leveling plate subjected first to what I may call a rough vertical adjustment and may then be adjusted with precision into the proper position.

My invention further contemplates means whereby when said device has been properly adjusted to maintain something which is to be mounted in a proper vertical position, may thereafter be lowered a definite predetermined amount so as to be easily moved away from the mounted object and moved to another position whereupon said means are brought into play to again level an element at the same height that the first element was leveled.

I will describe one form of my invention more in detail by referring to the accompanying drawing in which Fig. 1 is a front view of my device;

Fig. 2 is a side view thereof;

Fig. 3 is a sectional view on line 3-3 of Fig. 1;

Fig. 4 is a sectional view on line 4 4 of Fig. 1;

Figs. 5 and 6 are alternate positions of the means whereby the leveling element may be raised and lowered a definite predetermined distance, and

Fig. 7 is a view on line 7-7 of Fig. 6.

Referring more in particular to Figs. 1 and 2, I showI a top plate 1 mounted on four legs 2. These legs are slidable in surrounding legs 4 so that they may be moved vertically. Suitable braces 5 and 6 maintain rigidity of the structure in connection with two cross braces 7 and 8 to which said legs are fastened by means of clamps 9. Thus the structure consisting of the cross braces 7 and 8 and the said legs 4 is a rigid structure.

As will be apparent the top plate 1 carried by the legs 2 may be moved vertically as these legs 2 slide within the legs 4. The top plate 1 has a pedestal 10 fastened thereto which projects through cross brace 7. This pedestal 10 has a plurality of holes 11 by virtue of which the top plate 1 may when adjusted be held in a definite vertical position. The means for adjusting the top plate 1 and pedestal 10 consist of a pin 12 projecting from a lever 13. This lever has an extending arm 14 whereby it may be rotated. Thus if the element 13 is in the condition shown in Fig. 5 then the pin 12 rests upon the cross brace 7. Should the lever be rotated into its reverse position as shown in Fig. 6, then the pedestal 10, because of the action of the pin 12, is raised a definite predetermined distance. Surmounting the top plate 1 is a leveling plate 15 whose position is adjusted by three finger screws 16 into a definite vertical position.

In use my device may be placed against a wall where a cabinet or other article is to be fastened to the wall at a given definite height. The first adjustment consists of moving the top plate 1 vertically into a desired position wherein the leveling plate does not quite touch the element to be mounted. Under these condi- 2,889,126 Fatenfed June 2, 1959 ICC tions the pin 12 is in the position shown in Fig. 6. The leveling plate 15 being thus a small distance away from its proper leveling position is adjusted into its final position by the finger screws 16. The device is now in proper condition to support the element to be mounted on the wall which may for instance be a kitchen cabinet.

It is customary to have several cabinets mounted on a kitchen wall and it is, of course, imperative that they be mounted at the right height. Now after the first element has been mounted, the lever 13 is moved from its position in Fig. 6 to its position in Fig. 5 thus lowering the leveling plate a slight distance so that the leveling device may be slid away and into a different position where another cabinet is to be mounted at the same height as the first cabinet. After the device has been slid into such position to mount the second cabinet, the lever 13 is moved into the position of Fig. 5 thus raising the pedestal 10 to its proper leveling position which is the same position that it occupied when the first cabinet was mounted.

It will thus be seen that I have provide a device which serves a useful purpose in mounting different objects against a wall at the same height. Rough adjustment is provided by means of the holes 11 and pin 12. Fine adjustment is provided by the finger screws 16. In addition, means are provided which, without destroying the adjustment, may lower the leveling plate for easy removal of the device and for restoring the proper leveling position in connection with mounting of the second cabinet `or element.

From what has been thus described it is thought that my invention will be clear and what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described comprising a plurality of legs, cross braces fastened to said legs to form a rigid structure, a top plate having downwardly extending legs telescoping into said first aforesaid legs to permit of vertical adjustment relative thereto, and having a pedestal secured thereto extending through one of said cross braces, a cam and pin structure adapted to .engage said pedestal and said cross brace, a plurality of vertically spaced holes in said pedestal adapted to receive said pin for adjustment of said top plate relative to said cross brace, said cam portion when rotated serving to change the position of said top plate relative to said cross brace between fixed limits, a leveling plate surmounted said top plate, and means for adjusting the Vertical position of said leveling plate relative to said top plate.

2. A device of the character described comprising a plurality of legs, cross braces fastened to said legs to form a rigid structure, a top plate having downwardly extending legs telescoping into said first aforesaid legs to permit of vertical adjustment relative thereto, and having a pedestal secured thereto extending through one of said cross braces, and a cam and pin structure adapted to engage said pedestal and said cross brace, a plurality of vertically spaced holes in said pedestal adapted to receive said pin for adjustment of said top plate relative to said cross brace, said cam portion when rotated serving the change the position of said top plate relative to said cross brace between fixed limits.
