GUIDING MEANS FOR DRAWERS AND THE LIKE.

Application filed nuary 3 T0 wZZ whom, it ma/1. concern.-

Be it known that I, GEORGE C. GARDNER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Guiding Means for Drawers and the Like, of which the following is a specification.

My invention relates to certain new and useful improvements in guiding means for drawers and the like; and its object is to produce a device of this class which shall have certain advantages which will appear more fully and at large in the course of this specification.

To this end my invention consists in the novel features which are shown in the accompanying drawings as embodied in my preferred form of construction.

In the aforesaid drawings, Figure 1 is a section through a drawer and the cabinet in which it slides, showing my improved guiding means in elevation. Fig. 2 is a similar view showing the drawer pushed into the Fig. 3 is a vertical section in the line 3 3 of Fig. 2 looking from the rear. Fig. 4 is a section in the line 4 4 of Fig. 5, showing a modified form of the device used with heavy drawers; and Fig. 5 is a horizontal section in the line 5 5 of Fig. 4 through the modified construction.

Referring to the drawings, and particularly to Figs. 1, 2, and 3, A is a suitable cabinet having an opening in its front wall, through which runs a drawer B. My improved guiding means enables the drawer guides customarily used to be dispensed with, and the cabinet is therefore 'shown without such guides. A guiding-rod G extends longitudinally through the cabinet from the front thereof at least as far back as the point occupied by the rear of the drawer when pushed in to its farthest extent. In the form of the device herein shown the rod runs to the rear of the cabinet; but if a much larger cabinet were used it will be obvious that the rod could be terminated just behind the point occupied by the rear of the drawer when pushed in. A block D runs upon the guide-rod C, and the said block is pivotally connected by a link E to a second block F, guided upon a vertical guide-rod G, secured to the rear of the drawer B. To the rear face of the drawer, above the guide-rod G, is secured a bracket H, pivotally connected by a link I to a block J, secured to the link E be- Specification of Letters Patent.

tween its ends. A stop d is provided on the rod C for limiting the forward movement of the block D.

The operation of my device will be readily apparent. It will be seen that the block D is guided by means of the linksEand I, connected, as they are, to the drawer so as to be capable of longitudinal movement with respect to the drawer, but to be prevented from vertical movement With respect thereto. When, therefore, the drawer is pulled out from a position shown in Fig. 2, the block D runs along the guide-rod C and may or may not move backward with respect to the drawer. Whether such movement takes place depends, of course, on the friction of the block D on the rod C as compared with thefriction of the block F on the rod G and the friction of the various pivots of the links. Whether such movement takes place is, however, immaterial, as the vertical position of the block D with respect to the drawer remains con stant, and the drawer is thus horizontally supported at all times. When the drawer is nearly pulled out of the cabinet, the block D strikes the stop at and is held in lace while the drawer moves forward. In t is way the drawer is given a bearing on the guide at a distance Well within the cabinet and is held in a horizontal position when drawn as far forward as is shown in Fig. 1. When the drawer is pushed back into the cabinet, the block may occupy any longitudinal position with respect to the drawer, depending on the relative friction between the parts, until it strikes the rear of the cabinet or the stop on the guide-rod, when it is pushed up to the drawer and the links fold together, as shown, so that the entire guiding means occupy but a very small space.

Referring now to Figs. 4 and 5, a modified construction will be seen which is particularly desirable with heavy drawers where more than one supporting device is necessary. In such cases I prefer to use two guiding means and to substitute for the guide-rod C tracks C, between which run rollers D, secured to the upper ends of the links E. In this construction the brackets by which the links I and the vertical guide-rods G are secured to the drawer are modified slightly, so as to be attached to the side of the drawer instead of the rear; but this difference is evidently immaterial from a mechanical standpoint.

I realize that considerable variation is possible in the details of this construction without departing from the spirit of my invention, and I do not intend, therefore, to limit myself to the specific form herein shown and described.

I claim as new and desire to secure by Letters Patent- 1. The combination with an object to be guided to move longitudinally, of a guide adj acent to the path of the object to be guided, a member movable on the guide, a guide on the object to be guided, extending in a direction at right angles to said first-named guide, a member movable on said second guide, a link between said movable members, a second link pivoted at one end to the object to be guided, and at the other end to said first link1 between its ends, and a stop on said first m e. g 2. In a device of the class described, the combination with an object to be guided to move longitudinally, of a guide adjacent to the pathway thereof, a member supported by the guide, and movable thereon, a second guide on the object to be guided, extending at right angles to the first guide, a member movable on said second guide, a link connectionbetween said movable members, abracket on the object to be guided, a link connecting said bracket with said first link between its ends, and a stop on the first guide.

3. In a device of the class described, the combination with a cabinet and a drawer movable therein, of a horizontal guide adjacent to the path of the drawer, a member movable on said horizontal guide, a vertical guide on the drawer, a-member movable on the vertical guide, a link connection between said members, and a link connecting the first-mentioned link with the drawer.

4. In a device of the class described, the combination with a cabinet and a drawer movable therein, of a track adjacent to the path of the drawer, a roller running on the track, a vertical guide on the drawer, a member vertically movable on the vertical guide, a link connection between said member and the roller, and a link connection between said first-mentioned link and the. drawer.

In witness whereof I have signed the above application for Letters Patent, at Chicago, in the county of Cook and State of Illinois, this 27th day of January, A. D. 1905.

GEORGE O. GARDNER.
