MOLDING-BOARD STABILIZER.

Application filed July 5,

To all whom it may concern:

Be it known that I, HARRY A. HALL, a citizen of the United States, residing at ewcastle in the county of Henry and State of Indiana, have invented new and useful Improvements in Molding-Board Stabilizers, of which the following is a specifics tion.

The molding-boards of most kitchen cabinets are made to pull out while in use and to slide back into the cabinet-top when not in use as a working table. The board isdrawn out for greater accessibility and convenience while in use as a. table. The warping of the board and its easy movement in and out require that ample space be provided between the base and upper superstructure of the cabinet, and as the. result of. this loose fit the molding-board particularly it warped, has a vibration or wobble that is often noisy and disagreeable and which tends to a teelingof uncertainty on the part of the persons using it.

The object of this invention is to lock the molding-board in its drawn-out position and press the back edge of the board against the lower end. of the cabinet superstructure constantly with springsthat will prevent vibration without interfering with the nor mal movement in and out or the board.

I accomplish the above, and other objects which will hereinafter appear by the mechanism illustrated in the accompanying drawing, in which Fig 1 is a View in end elevation of a kitchen cabinet provided with my invention, and showing the molding-board in its inner or closed position in full lines, and in its drawn-out position in dotted lines.

Fig. 2, is a vertical cross-section of the cabinet showing the molding-board in its drawn-out position, and Fig. 3 is an under side plan view of the molding-board detached.

Like characters of reference indicate like parts in the several views of the drawing.

Referring to Figs. 1 and 2, 4c is the base and 5 the cabinet top or superstructure attached to and supported suitably above the base by plates 5, in the usual manner. The molding-board 6 rests upon the base 4 and is slida-ble thereon in and out, under the superstructure 5. The latter has a bottom 7 immediately under which the board 6 is as- Speeification of Letters Patent.

Patented Mar. 7, 1922.

Suitable recesses are provided in theupper edge of the front of base 4 to receive the strips 8. Secured to and depending,

' from the strips 8 are the stop-blocks 9 which are suitably placed to contact the front wall of base at and arrest the outward movement of the mold-board 6 while the back edge of said board is still under and in contact with the bottom 7 of the superstructure 5. This limits the outer movement of the mold board 6. This stop-bloclrQ is preferably wedge-shape as shown in Fig. 2 and is assembled with the taper toward the rear of the cabinet. A smaller stop-block 1O isse cured to and depends -I"rom each of the end strips 8. These stop-blocks are spaced far enough from and in front of the stop-block 9 to receive the front wall of the base i between the blocks, thereby serving to positively hold the moldboard in its drawn-out position. The stop-blocks 10 are wedgeshape and have the tapers turned outwardly to Mt the mold-board on their inclines when the board is drawn-out.

Secured to each of the strips 8 and depending from the inner ends of said strips are wedge-blocl-rs 11.

At each end of the base 4: in the interior of the base are the horizontal members 12, upon each of which a leaf-spring 13 is mounted. The rear end of each spring is free and is bent upwardly in a curve to con tact the adjacent strips 8 of the mold-board, and they are so placed that when the moldboard is drawn out to its fullest extent, 7

shown in Fig. 2, the free ends of springs 13 and stressed by said blocks in a manner to force the inner edge of the mold-board yieldingly into contact with the bottom '7 of the superstructure 5. The taper of the wedge block 11 enables the mold-board to be drawn out against the curved end of spring 13, and the taper of the stop-blocks 9 permits the block 9 to depress its springs. The springs 13 thus hold the mold-board against the bottom 7 in a manner to prevent vibration, and the resiliency of the springs allows for the necessary adjustment to prevent binding.

Having thus fully described my invention, what I claim as new and wish to secure by Letters Patent of the United States,

1. In a cabinet, a base, a superstructure, a mold-board out-he base slidable loosely in and out under the superstructure, wedgeshaped stop-blocks to limit the outer moven'ient of the mold-board, their tapers being toward the rear of the cabinet, means for holding the mold-board against inward slid able ad ustment when 111 its outer position or use, wedge-blocks on the inner edge of the mold-board with their tapers turned toward the front of the cabinet, and fixed leatsprings secured at their front ends and carried upwardly and rearwardly into contact with the mold-board between said first and last "wedge blocks, which blocks have their tapers toward the springs to ride over and rompress the springs when the mold-board is moved in their respective directions and prevent lost motion of the'mold-board.

2; In a cabinet, a base, a superstructure, a mold-board on the base slidable loosely in and out under the superstructure, wedges shaped stop-blocts to limit the outer 1nove- 'mentofthemold-board, means for holding the mold-board against inward slidable adjustment when'i'n its outer position of use, wedgerblocks further inward of the cabinet, said first and last named wedge-blocks having their respective tapers toward each other,

1 scenes and leaf-springs secured at one of their respective ends and curved toward the other to contact with and to be compressed by said first or last wedge-block as the mold-board is moved in their respective directions and prevent lost motion of the moldboard.

In a cabinet, :1 base, a superstructure, a meld-board on the base slidable loosely in and out under the super-structure, wedge shaped stop-blocks to limit the outer movement" of the mold-board, their tapers being toward the rear of the cabinet, wedge'stopblocks nearer the outer edge of the moldboard a distance to receive the trout ot the rabinet base between themsaid last blocks having outward tapers to ride over the cabinet front when the mold-board is drawn out,

wedge blocks on the inner edge of the mold- .board with their tapers turned toward the frontof the cabinet, and fixed leaf springs secured. at their front ends and curved upwe rdly and rearwardly into contact with the mold-board between said first and last wedge blocks which blocks have their tapers toward the springs to ride up over and compress the springs when the mold-board is moved. in their respective directions and prevent lost motion of the mold-board.
