Annndertanding' of the invention maybediad from the following description, taken in connection with the accompanying drawing, in which:
Fig. 1 isa fragmentary perspective and vertical sectional view showing my invention in connection with a horizontal slide,
Fig. 2 is a fragmentary vertical section showing a drawer mounted between space supporting sides of a pedestal or the like and utilizing my invention, and
Figs. 3 and 4 are enlarged transverse vertical sections through the guide structures which are used at the opposite sides of a drawer or opposite edges of a slide.
Like reference characters refer to like parts in the different figures of the drawing.
A drawer is generally mounted for horizontal movement between two spaced apart vertical sides I of a desk pedestal or similar casing structure, for example a ling cabinet, bureau or the like. The drawer has spaced vertical sides 2, a bottom 3 and ends 4 of conventional type.
For slidably mounting and guiding the drawer, at the inner side I of the pedestal, a lower guide member of thin sheet metal is located and secured. It is formed with a vertical flange 5 to lie against the inner side of the associated pedestal side I, being secured thereto, preferably by screws. From the upper edge of the flange 5 a relatively wide horizontal ledge 6 extends inwardly, from the inner edge of which an inner vertical leg I extends upwardly and is curved outwardly into substantially U-iorm, terminating in a downwardly legs I and 8 is of a relatively large radil-l'srclirvai5 f1substaritialflistanceffrom=eachcther; greater than the thicknessfof fthe 'fn-fetal u'sed,1=andfare'iloeated in substantially Iparallel Vertical planes.

The nooperating upperf--guideimembennsed wtih nthe A.drerwer'isalso-Ithinfslfreet-fmetaL havinglan Jthe distancelbetween thell'egs Il "and ft2? beingflthe same as between the legs 1 and nsai'dupper and lower members of the guide, as shown in Fig. 4 are slidably interlocked with the terminal leg 8 between the legs II and I2, and the leg I2 between the legs 'I and 8. The two members, one upper and one lower of the guide, are identical in structure and are reversed in position.
Similarly the upper guide member, at the upper side of the drawer has its ledge Illa narrower in width than the ledge I0. The slidable interlock connection is the same. The spacing of legs l I and I2 and 'I and 8 is such that said legs 8 and I2 are close together, and also in close relation to the outer legs 1 and I I, while the structure of the other guide with the wider spacings of legs 'I and 8 and II and I2 permits a lateral movement of the upper and lower guide members which is not permitted at the other side of the drawer.
With the structure and assembly as described the more closely connected guide at one side of the drawer, that at the left in Fig. 2, holds the drawer from sidewise movement and maintains the drawer movement in a substantially straight line. At the same time there is a wider tolerance relative to the width of the drawer, because the more loosely connected members, those at the right in Fig. 2 permit a lateral change of position of the legs I2 and 8 with respect to each other. The closer tolerance which would be required if both guides were of the type in Fig. 3 is not needed. Also any change in dimension due l l, 3 to shrinking or swelling is taken care of without danger of binding and resistance to the movement. v
Substantially the same guides are used with a horizontally mounted slide, such as I3 in Fig. 1. The lower guide members are identical with those in mounting a drawer as in Fig. 2. The upper cooperatingV members are changed only by not bending -up theflange 9 but extending it in the same plane with the horizontal ledges I0 and Illa, as indicated at |00 in Fig. 1, so that said flanges located against the under side of slide I3 at opposite edge portions may be screw connected to the slide. The action and results obtained are the same as with a drawer.
The invention has proven very practical and; useful. The elimination of custom fitting of slides and drawers to the pedestals in which they are mounted thus eliminates high priced labor and reduces costs, witha certainty that binding, sticking, and other common undesirable occurrences in drawer and -slide movement will not happen.
The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
I claim: i 1. In a structure as described, two spaced parallel vertical supports, a, memberlocated between -said supports for slidable connection therewith to.,
move in a substantially horizontal plane, a twopart guide having one part connected with the innnerV side of one of said vertical supports and the other part to said member, said two parts of the guides being identical and having inter-,f a
engaging U-shaped connections relatively movable longitudinally one with respect to thel other, and relatively closely connected to prevent lat- `eral play therein, a second two-partV guide having one partthereof connected at theinner side, of the other of the verticalsupports and the other part connected to said member, having engaging inter-connecting U-shaped portions loosely con- Y nected laterally and associated to permit lateral Y play therein.
v U-s-haped portion, a second guide member xed to the outer side of each side of the drawer extending outwardly therefrom and-terminating in a vertically positioned U-shaped portion, the free legs of said U-shaped portions inter-connecting with each other, said guide members at one side eral movement.
of the drawer having inter-connecting U-shaped 'portions in relatively close engagement to prevent lateral movement or play therebetween, and at the other side the legs of said U-shaped portions being spaced to allow lateral movement.
3. In a structure as described, two spaced apart vertical supports, a member located between -themand mounted for sliding movement and a two-part guide between each vertical side of said sliding member and its adjacent support, one part of each guide being attached tosaid sliding memberand the other part thereof attached to a support, the two parts of said guides each having interlocking U-shaped portions and other` portions extending past the curved partuof ,the U-shaped portion ofthe other part andv closely adjacent to it, the interlocking portions of one guide being closely spaced to prevent relative lateral movement and the interlocking portions of the other guide being widely spaced to permit relative lat- B'ERTRAND ML BAKER.
