DRAWER OR SLIDE EQUALIZER.

SPECIFICATION forming part of Letters Patent N 0. 781,562, dated January 31, 1905.

' Application filed October 10, 1904. Serial No. 227340.

To all whom it may concern Be it known that 1, LIBORIUS SENGE, a citizen 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 Equal plify and cheapen the construction of equal izing devices ofthis character, and, third,to so arrange the equalizing devices that they v will give the greatest area or capacity possible in compartments in which they are fitted, as in bookcase units, to permit taller books to be placed in such compartments than could be if equalizing devices of old and well known kinds, somewhat resembling mine, were used.

The'novelty of my invention will be hereinafter more fully set forth, and specifically pointed out in the claims. 7

In the accompanying drawings, Figure 1 is a partially-broken plan view of a well-known form of bookcase unit with the slide-door. raised andv partially pushed in. Fig.2 is a sectional side elevation of Fig. 1 on the dotted line 00 m of Fig. 1 looking to the right. Fig. 3 is a corresponding section with the door drawn entirely out and closed. Fig. 4 is an enlarged detail of. a part of the slidingequalizing mechanism. I I

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

. In the drawings is shown a single bookcase unit of well-known construction, of which 1 represents the end walls; 2, the back wall; 3 and 1, the interlocking top and bottom pieces connecting the end walls, and 5 the sliding and swinging door, which is usually a glassfilled frame adapted to entirely close the front opening of the unit when pulled outand let down and which can be raised and swung up on a pivot and pushed back intothe top of the case to give free access to-the interior thereof.' The edges of the door when pushed back rest upon and slide upon any suitable guides secured to the side walls. In this instance they rest and slide upon metal strips 6, se-

cured to and slightly projecting from the side walls, and hook-like projections 7 on the un- 'der side of the top rail of the door are adapted to engage'with the front screws 8, which serve to secure the strip 6 in place and. also serve as stops to prevent the door from being drawn out too far, and, further, serve as pivots upon which the door can be swung down to a closed position, as seen in Fig. 3. r The equalizing, mechanism which holds. the door straight in its movements in and out of the case consists of two cross-arms or thin flat bars 9 and 10, loosely pivoted together at their middle, as [at 11, Fig. 1, and having their forward ends slightly reduced and curved and passed through guide-eyes, which may beordinary screw-eyes 12, secured to the top edge of the door-frame 5. The rear end of the bar 9 is fixedly pivoted, as at 13, in any suitable manner to the rear wall of the case, while the rear end of the bar 10 is pivoted to a rod or bar 14, as at 15, (see Figs. land 4.) which rod or bar is confined in bracket-guides 16, secured to the rear wall of the case near its upper edge.

This construction forms a very simple lazytongs arrangement by which the door is held from binding in its movements in and out, and thus constitutes a perfect equalizer, while at the same time it is placed so high up in the case that it permits the entire capacity of the case to be utilized without interfering with the working of the door, as will be readily understood.

Having thusfully described my invention, I claim I 1. In a drawer orslide equalizer, the comor drawer adapted to cover the open front of the case when drawn out and lowered and to 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 having their rear ends, the'one of them stationarily pivoted to the back of the case and the other pivoted to a slide guided in brackets secured to the back of the case, the connections of the cross-bars with the door and the case at their ends being substantially opposite each other and located at the extreme top of the case, substantially as described.

2. In a drawer or slide equalizer, the combination with a case, of a sliding hinged door or drawer adapted to cover the open front of the case when drawn out and lowered and to be raised and pushed back into the top of the case to give free access to the same, guides at the ends for the sliding of the door, stophinges at its forward end to limit its outward movement and to permit it to be lowered to close the case, cross-bars pivoted at or near their middle and having their forward ends slidably connected to the top edge of the door at each side and having their rear ends, the one of them stationarily pivoted to the back of the case and the other pivoted to a slide guided in brackets secured to the back of the case, the connections of the cross-bars with the door and the case at their ends being substantially opposite each other and located at the extreme top of the case, substantially as described.

3. In a drawer or slide equalizer, the combination with a case, of a sliding hinged door or drawer adapted to cover the open front of the case when drawn out and lowered and to be raised and pushed back into the top of the case to give free access to the same, the crossbars 9 and 10 pivoted at or near their middle and having their forward ends slidably connected to the top edge of the door at each side by screw-eyes 12 and having their rear ends, the one of them stationarily pivoted to the back of the case as at 13 and the other pivoted to a slide 14 guided in brackets 16 secured to .the back of the case, substantially as and for the purpose specified.
