` SPECIFICATION forming part `of Letters Patent No. 781,561, dated'January 3.1, 1905K. Application lled October 10, 1904. Serial No. 227,839.

To all whom t may Concern:

Be it known that I, LIB'oRrus SENGE, acitizen of the United States, residing at Crescent Springs, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Drawer or Slide Equalizers, of which the following is a full,- clear,

and'eXaet description, reference being had to the accompanying drawings, forming part of this specilication. v

This invention relates to a new and useful deviceforequalizing themovementof drawers, slide-doors, desk-shelves, and the like; and the vsame consists in the combination and arrangement of parts hereinafter described.A

The objectsof the invention are, first, to furnish a device which will prevent a drawer, door, or slide which moves horizontally into and out of its .case frombinding and cause both ends to moveuniforrnly; second, to simplify and cbeapen the construction of equalizing devices of this character, and, third, to so larrange the equalizing devices that they will; give thel greatest area or capacity possible in compartments in which they are tted, as in bookcase units, to permit taller books to be placed in such compartments thacould be if equalizing devices of old and well-known kinds somewhat resemblmg mine were used.

The novelty of my. invention will be hereinafter more fully vset forth, and specifically pointed out in the claim. -V

In the accompanying drawings, Figure l is a partially-broken plan view of a well-known form of bookcase unit with the slide -door raised and partly pushed in. Fig. 2 is a sectional side elevation ofv Fig. l on the dotted lines w a' and Ylooking to the left. Fig. 3 is a sectional elevation on the dotted line y y of Fig. `1 looking to the right.

The same numerals of reference are used to indicate identical parts in all the figures. v

`In the drawings is shown asingle bookcase unit of well-known construction, of which l represents the end walls; 2, the back wall; 3

4, the interlocking top and bottom pieces connecting the end walls,-and 5 the swinging and sliding door, which is usually a glass-'filled frame adapted to entirely close the front openingvof the unit when let down and which can be raised or` swung up on a pivot and pushed back into the top of the case to give free access to the interior of theunit.

`Extending through eyes 6, which may be ordinary screw-eyes secured to the upper edge 7 of the door-frame, are the slightly-curved outer ends of two lever- arms 8 and 9. These are loosely pivoted together at their middle,

as at 10, and the arm 8 is pivoted as high up as lpossible to a bracket-piece 1'1, secured to the inner sideof the rear wall 2, as seen in Fig. l, while the inner end of the opposite farm 9 iscurved and passes vthrough an eye# guide 12, as high up as possible on the rear wall 2 of the unit. This construction brings the -arms 8 and y9 as high up in the unit as possible and at the same time forms a perfect Veopualizing device, and theedge of the door when raised rests and rides upon a roller 13, `secured to the inner side of each end ywall of the unit, near its front end, a suitable stop 14 Y'being provided onthe door-frame to prevent its being pulled too far out and to serve as pivots upon which the door can vbe let down lto its closed position. (Shown in Fig, 3.)

By this simple construction I provide equalizer mechanism which is cheap and thoroughly case when drawn out and loweredn and t'o be raised and pushed back into the top of the case to give free access to the same, crossbars pivoted at or near their middle and having their forward. ends slidably connected to the top edge of the door at each side, and havextreme top of the case, Substantially :1S deing their rear ends, the one of thern stationscribed. arily pivoted to the heck of the ease and the T other slidably connected t0 the back of the LIBOH'IUb blubhh 5 cese, the connections of the cross-bars with \Vit1iesses:

the door and case at their ends being su bstan- E. Z. BRAGG,

tially opposite each other and located at the EDWARD Picon.
