JOSEPH HENRY KNAUS, OF FAYETTE, MISSOURI.

FURNITURE-DRAWER.

SPECIFICATION forming part of Letters Patent No. 427,475, dated May 6, 1890..

Application filed June 18, 1889. Serial No. 314,741. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH HENRY KNAUS, a resident of Fayette, in the county of Howard and State of Missouri, have invented certain new and useful Improvements in Furniture-Drawers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The object of the invention is a device for equalizing the pressure on the sides of furniture-drawers; and it consists in the combination and arrangement of parts hereinafter described, and particularly pointed out.

In the accompanying drawings, Figure 1 is a perspective View, a part being broken away. Fig. 2 is a bottom plan View of the pressure equalizing mechanism on an enlarged scale. Fig. 3 is atransverse section on the line as as; and Fig. 4: is a side elevation, partly in section, of a detail, the parts being detached.

The drawer 1, having a back 4, is represented as partly withdrawn from case 2, which latter may belong to a bureau or other article of furniture. To the rear side of the case a block 3 is secured by any well-known means, and in any convenient place. To this block a bar 6 is secured pivotally by a screw 5' or by like means in such manner as to allow a circular movement of said bar, the opposite end of which is provided with a pin, screw, or like device 10, adapted to enter slot 7 in a bar 8, and to be moved lengthwise of the same.

Bar 8 is composed of two parts separated by a space about the thickness of the rear part of the drawer, and connected by pins,screws, or bolts 9. The upper edge of the drawer-back is recessed, as indicated, to receive the pins 9, and when these are dropped into the recesses the two parts of the bar 8 rest one on each side of the back of the drawer. The front portion of bar 8 is made sufficiently wide to admit forming therein the slot 7, the other portion of 8 being preferably made narrower to allow the drawer to be pushed close to the rear of the case. Under the center of bar 6 is pivoted a bar 11, the opposite end of which also has pivoted connection with bar 8. A spacing-block 12 is interposed between the end of bar 6 and the slotted bar 8, and the before-described pin 10, which works in slot 7, passes through the same. This block 12 has about the same thickness as bar 11. It would be possible to pivot the bar 6 elsewhere than to the under side of bar 11, and in such case the spacing-block might be omitted, and even though pivoted as represented the device would operate without block 12. It is, however, preferably used. \Vhen the drawer is closed, the pin 10 is in the outer end of the slot 7, and when it is opened said pin moves to the opposite end as the bar 6 is swung outward and around the pivot 5. If new the right-hand pull be used, the tendency to move the right side of the drawer faster than the other and cause the drawer to bind between the walls of the case will be obviated by the pull of bar 11 upon bar 6, which latter, byits connection with the drawer-back, moves the central and left-hand portions of the drawer in parallel lines with the right-hand side, and so obviates any binding or jamming at the sides. In like manner, if the left-hand side of the drawer be pulled, the force is transmitted through the drawer to pin 10 and bar 6, which latter thrusts or pushes bar 11, which latter acts upon the right-hand side of the drawer to cause it to move in unison with the left side. Similar effects are produced when the drawer is pushed back to close it, and the device acts very efficiently to prevent the sticking or binding which is so common and annoying in articles of this nature.

The present improvement relates to the particular means for readily attaching and detaching the drawer from the equalizing mechanism. When constructed as above described, the drawer can be entirely removed by simply raising bar 8 above the top of the back 4. This lifts the pins 9 out of their seats and entirely disconnects the system of bars and the drawer, which latter can then be entirely removed from its case, and it is obvious that it can be readily returned and joined or connected with the equalizing mechanism. This means of connecting the drawer and equalizing mechanism avoids all fixtures upon the drawer and is of such nature that it can very readily be applied to drawers al= ready in use. Further, the rear of the drawer is sustained against fracture by the double bar 8, which embraces it upon both sides, which is a desirable feature, especially when thin stuli is used.

Ordinarily the above described press ureequalizing device will be made about twothirds orthree-fourths of the length of the drawer. In short drawers, however, it is made as long as the drawer itself to secure sufficient outward throw. The bars are preferably made of wood. It I is preferred to make bar 11 about half as thick as bar 6, and narrower than the same; but obviously the invention isindependent either of particular material or the precise dimensions.

Having thus described my invention, what I desire to secure by Letters Patent is as follows:

In devices for equalizing the pressure on the sides of drawers moving in ways or in a case, a bar pivoted at one end thereof to the case, the other end being provided with a pin movable in a slot in a bar connected with the drawer, a second bar pivoted to the last-named bar and also to the central point in the firstnamed bar, the double bar 8, the members of which are separated bya space as wide as the thickness of a drawer-back and connected by transverse pins, as 9, in combination with the drawer having the upper edges of its back provided with notches cut entirely across the same to receive said transverse pins, whereby said compound bar embraces both sides of the drawer-back and can be removed therefrom or applied thereto by simply raising or lowering the bar and horizontal pins, substantially asset forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOSEPH HENRY KNAUS.
