cHAnLEs J. sEvEnANcE, or WAcoUs'ra, MICHIGAN@ DESK-DRAWER.

To all whom t may concern:

Be it known that I, CHARLES J. SEVER- ANCE, citizen of the UnitedStates, residing at -lVacousta, in the county of Clinton and State of Michigan, have invented' certain new and useful Improvements in Desk- Drawers, of which the following is a specifcation.

This case relates to desk drawers, and more particularly to a drawer specially adapted to be used in connection with desks having inclined tops.

One of the main objects of the invention is to provide a drawer of the character stated which will not slide out of its casing by gravity due to vibration or other causes. A further object is to provide a drawer of simple construction and operation which can be readily secured in any desired adjustment. Further objects will appear from the detail description.

In the drawings:

Figure 1 is a longitudinal vertical sec tional view through the drawer as. applied taken in a plane near one side of the drawer.

Fi 2 is a transverse section taken on the hne 2-2 of Fig. 1.

Fig. 3 is a transverse section through the drawer and its casing looking rearward taken on la line slightly in advance of the stirrupV for limiting outward movement of the drawer.

Fig. 5 is a fragmentary plan view of the drawer casing showing the rack portion of the same.

The numeral 1 designates the downwardly and forwardly inclined top of a desk. To the under face of this top, near oneend thereof, are secured two parallel supporting strips 2. These strips vare provided with horizontally extending rabbets adapted to receive the laterallyprojecting flanges 3 at the upper edges of the side walls 4 of the This casing is also provided, at the upper edges of its side walls, with inwardly projecting flanges 3a.

their lower ends, with apertures 7a and, 8,

respectively. Theseapertures are positioned y. Patented May 29, 1917. Application mea August 15, 1916'. serial No. 115,025.

near one side of the drawer and rockablysupport a longitudinally extending locking rod 12. The inner portion of this bar is turned inward at right angles, as at 13, and is then bent downward at right angles to form an engaging latch 13a. The portion 13 and latch 13a are positioned in the space between the inner end 6 of the drawer and the partition 7 solas to be movable vertically without engaging the contents ofthe drawer. At its outer end the rod 12 is turned inward at right angles as at 14 and is then bent outward at right anglesas'lat 14a.` The outer end of the portion 14EL projects into a slot 15 through ya plate 16, near the lower end thereof. This plate is provided, at its side edges,with integral longitudinally extending sleeves 17. These sleeves are slidably mounted on' guide rods 18 ysecured to the outer end 6b of the drawer in spaced relation to the inner base thereof. A thumb knob 19 is secured to plate 16 by means of a'screw 20 tlreaded thereinv and passed through the p ate. tical slot 21 in the front' wall of the drawer. A fixed. abutment or knob 22 is secured to the front wall of the drawerr in vertical alinement with the thumb knob 19.

A coil spring 23v is mounted about the rod 12 adjacent the frontpartition 8 of the drawer. The forward end of this spring is extended laterally to form a linger 23a which rests against the bottom 10 of the drawer so 'as to prevent uncoiling of the spring. The inner end of the spring is secured to the the bar downwardly'and inwardly so as to force the latch member 13a at the inner end' This screw extends through a ver-b children,

thereof downward. The 'downward movement of the latch member is positively limited by a stop pin 25 secured in the inner partition 7 `and projecting beneath the horizontal portion 13 of the bar. l

The bottom 11 of the drawer casing 1s rovided, at its transversecenter, wlth a ongitudi'nally extending series ofspaced recesses 26 of arcuate shape. These recesses 'constitute in effect a rack bar adapted to be .drawer may be moved in or out of its casing as desired. As soon as the thumb knob is released the spring 23 acts to return the latch member 13a to operative position so as to lock the drawer against movement. It will be evident that, by this construction, the drawer is prevented from sliding out -of its casing while it may be quickly and easily openedor closed, as desired. Also, by having the ,recesses 26 of arcuate shape and with vertical inner and outer walls, the

drawer cannot be moved inward without raising the latch member mto inoperative position. lThis renders it impossible to force the drawer inward so as to create a loudv noise such as would occur if a ratchet bar.` of ordinary construction with rearwardly inclined teeth were used. rThis feature is of importance as eliminating all possibility of thel creation of unnecessary noise by school as this invention is intended especially for use in connection with school desks. This drawer provides a receptacle for holding the pencils, pens, and similar instruments used by the pupils in such a manner as to be readily accessible while, as

above noted, completely eliminating all possibility of the creation of unnecessary noise.

In order to prevent withdrawal of the drawer from the casing, a limiting U-member or stirrup is suspended from the top edges of the sides of the casing with its horizontal bar 27 and arms 28 inside of the drawer. The arms28 are turned outward at right angles at their upper ends to form suspending arms 29 which are loosely mounted through apertures through the casing walls. Each of the arms 29 has its outer portion turned downward at right angles to provide stop members 30. These members are adapted to engage the under faces of the flanges 3 at the top edges of the walls 4 of the casing so as to prevent rotation of maare? the stirrup about its pivotal arm 29 beyond a predetermined point. By this means the stlrrup cannot be rotated rearwardly and upwardly so .as to be raised out of position to engage the inner partition 7 of the' drawer. One of the stops 30 is adapted to engage a lug 31 formed integral with and projecting from one side of the casing. This prevents forward rotation of the stirrup beyond a predetermined point so as to render it impossible to rotate the stirrup outward and upward into inoperative position. By this means the drawer, while it may be slidably adjusted in its casing, is prevented from being entirely lwithdrawn from the same.

There may be slight changes made in the construction and arrangement of the various parts of my invention without departing from the field and scope of the same,'and ll intend to includeall such changes, as fall within the scope of the appended claims, in this application in which apreferred form only of my invention is disclosed.

What l( claim, is

1., Tn a device of the character stated, a casing provided in the' inner face of its bottom with a longitudinally extending series of recesses, a'drawer slidable in said casing,

a locking rod rockably supported by the drawer beneath the bottom thereof, the inner endof said rod being bent to engage into said recesses when the rod is depressed, and means for operating the rod exteriorly of the drawer.

2. TnV a device of the character stated, 'a casing provided in the inner face of its bottom with a longitudinally extending series of recesses, a drawer slidable in said casing,

a locking rod rockably supported by the drawer beneath the bottom thereof and having its' inner end bent to engage into said recesses when the rod is depressed, means for'normally holding said rod depressed, a thumb knob slidably mounted on the front of said drawer, and connections between said knob and rod for raising the rod out of' engagement of said recesses when the knob is raised.

3. In a device of the character described,-

the combination of a casing provided with a plurality of recesses in its bottom, a drawer slidable in the casing and having. its bottom in spaced relation to the bottom of the casing, said drawer being provided with a transverse partition spaced from each end wall, a rod carried by the drawer and rockably mounted therein between the bottom of the drawer and the bottom. of the casing, said rod being provided at its inner end with an integral latch member .positioned between the inner end and the inner partition of the drawer and adapted to engage the said recesses in the bottom of the casing, a coil spring mounted` about the rod and adapted to normally hold the latch member 13e ond of the rod whereby the rod is rotated so as to lift the latch member .into .inoperative position when the plate 1s ralsed.

In testimony whereof I aix my signature in presence of two witnesses.

CHARLES J. SEVERANCE.
