DRAWER-MOUNTING.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Application filed March 13, 1917. Serial No. 154,609.

T 0 all whom it may concern:

Be it known that I, BERT WALL, a citizen of the United States, and resident of Mason City, in the county of Cerro Gordo and State of Iowa, have invented a certain new and useful Drawer-lvlounting, of which the following is a specification.

The object of my invention is to provide a. drawer mounting of simple, durable and inexpensive construction.

A further object is to provide a drawer mounting so constructed and arranged that a drawer may be mounted upon rollers and may be properly supported on said rollers in all positions of its sliding movement, especially so that it may be supported by the rollers against tilting movement and against binding after the drawer has been partially drawn out.

Still a further object is toprovide such a drawer mounting so constructed and arranged that parts may be readily and easily removed or assembled for mounting the drawer in a bureau or the like, or removing the drawer therefrom.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, wh reby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which: I

Figure 1 shows a horizontal, sectional view of my improved mounting, taken on the line 11 of Fig. 2.

Fig. 2 shows a vertical, sectional View, taken on the line 2-2 of Fig. 1.

Fig. 3 shows avertical, transverse, sectional view, taken on the line 33 of Fig. 2.

Fig. a shows a front elevation of a part of the mechanism illustrating the manner of mounting one of the rollers at the front of the drawer.

Fig. 5 shows a vertical. sectional view taken on the line 55 of Fig. 1.

Fig. 6 shows a vertical, central, sectional view through a drawer equipped with a mounting embodying another form of my invention, taken on the line 6-6 of Fig. 7.

Fig. 7 shows a transverse, vertical, sectional view taken on the line 77 of Fig. (i.

Fig. 8 shows a vertical, sectional view, taken on the line 8-8 of Fig. 6.

Fig. 9 shows a perspective view of one of the bearing brackets and toothed rollers therein, and

Fig. 10 shows a detail view of the forward end of one of the channels of the modified form of the device, showing the notch on the upper flange thereof.

In the accompanying drawings I have shown one form of my invention in Figs. 1 to 5 inclusive, in which I have used the ref erenoe numeral 10 to indicate generally the rear wall. of a bureau or commode or the like, having the side walls 11. The bureau is provided with upright supports 12 spaced from each other and secu ed to the inner surface of said rear wall 10.

Secured to the supports 12 for each drawer there is a pair of channels arranged opposite each other, each being secured to one of the uprights 12 and opening laterally outwardly and extending horizontally forwardly in the bureau. The channels are indicated by the reference character 13. The upper flange of each channel 13 is cut away for a short distance at It at its forward end. 7 I

The forward end of each channel is supported in the following manner. Received between the sides 11 at the front of the bureau between each successive pair of drawers from top to bottom, is a cross piece 15. Secured to each cross piece 15 near the end thereof on the inner surface thereof is a small angle 16 held in position by a screw bolt 17 extended through the cross piece 15 and one flange of the angle 16. The other flange of each angle 16 is secured to the center wall of one of the channels 13, as shown in Fig. 1, by means of screws 18.

The inwardly extending flange of each angle iron 16 is provided with a slot 19. The forward end of the central portion of each channel 13 is provided with a slot 20, shown by dotted lines in Fig. 5. The parts are so arranged that when assembled the inner ends of the

slots

19 and 20 register with each other, as shown in said Fig. 5.

Extended through said slots is a shaft 20 having on each end a roller 21, formed on one end of which is a toothed gear or the like 21", the teeth of which extend upwardly through the slot 14. as illustrated in Fig. 2.

A supporting strip 22 has its ends secured to the side walls 11 at the front of the bureau and serves to support the front ends of the channels 13, as clearly shown in Figs. and 2.

Each drawer has a rear wall 23, side walls 24 and a front wall 25. The walls are of such width that at the sides they project over the channels 13, as illustrated in Fig. 3; The lower edge of each side wall 2% is'p-rotected by a strip of iron 26, or the like, which travels on one of the rollers 21.

Secured to the outer surface of each side wall 24 near the rear end thereof, is a'rigid bracket 27 extending downwardly below the side of'the drawer and supporting at its lower end an inwardly'exten'dingshaft 28 on. which is mounted a roller 29 which travels within the channel 13.

Nearthe inner end of each strip 26 said strip is provided with teeth 26, as shown in Fig. 3. It may be mentioned in'this connection that the smooth roller 21 is so located that its upper surface stands just above the upper flange of the channel 13 in which the roller is mounted. The parts are so arranged having a bottom 53, the rear wall 5%, side walls 55 and a front wall 56.

Mounted on the bottom of each drawer a bracket 57 having portions extending downwardly adjacent to one of the channels- 52' and supporting a shaft57 on which are rollers 58'received within said channels. The

upperflange of each channel 52 at its forward end is formedwith anotchsimilarto the notch or cut-away portion'lel, as shown in Fig. 10, indicated by the reference character 59.

V Atthe forward end'of each channel 52 is channel-shaped bracket opening outwardly with its upper and'lower flange members receiving between them the channel 52,'said bracket being indicated by the numeral 60. Each bracket is secured to its adjacent channel 52 by screw bolts 61. Each. bracketGO has a notch 62 cut in its upper fiangei The central portion of each bracket 60 forms a bearing for a transverse shaft 63 extending across between the side walls of the main frame.

On the outer end of each shaft 68 is a roller 64 similar to the roller 21, having formed at one end a gear 65 similar to the gear 21 v On the bottom of each drawer near each side thereof, is a metal strip 66 adaptedto rest and travel on one of the rollers 64', and having a portion 67 formed with teeth to engage and coact with the teeth of one of the gears 65, as shown in Fig. 6. V

In the practical construction and use of my improved drawer mounting it will be position, after which the rollers 21, and

angles'16 are assembled and'thereafter'the pieces 15 are placed'in position. It will be obvious that the strips'l5and rollers 21 may be readily and easily'removed for remov ing the drawer from the bureau for repair- 111;; it or replacing parts.

In the use of the drawer it' will be seen that when the drawer 'is at the rearward 'be no binding of the drawer atany part of its sliding movement. a

The form of the device shown in Figs. 6 to'10 inclusive may be used with'cross members 15 similar to those shown in Fig. v1, which may be secured to the side' members 51, but when the form used in Figs. 6 to lOis employed, the angle irons 16 may be.dispcnsed with- 7 p I If it is desired to remove one of-the drawers shown in F ig." 6, for instance, the' memberl5 may be removed, afterwhich the screw bolts 61.are'removedTandthebrackets 60 and the shaft 63 are removed from the front of the main frame. Thereafter the drawer may he slid out of the'main frame without difficulty. 7 f

Some changes maybe made in the con struction and arrangement "of my improved drawer mounting without departing from the essential features andpurpo'ses of my invention, and it is myintention tocoverby' my present application any such modified formsof structure as may be'reasonably in eluded within the scope of'my claims- I claim as my invention: .7
