CABINET-DOOR.

Specification of Letters Patent.

Application filed November 80, 1909.. Serial No. 530,558.

To all whom it may concern:

Be it known that I, Hueo R; Knnns'rnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cabinet-Doors, of which the following is a specification.

.This invention relates to that type of cabinet door which is adapted to form a closure for the cabinet when swung into one position, and which, when released from such position, will swing into a position parallel with the side walls of the cabinet body, and when the latter position is reached will be acted upon by suitable mechanism and drawn back into the interior of the cabinet body.

The object of the present invention is to construct a door with the above described properties, in which the operation will be automatic which draws it back into position.

' within the interior of the cabinet; in which the movement will be automatic which swings it into position to be acted upon by the mechanism to draw it back into the interior of the cabinet; which will be securely locked when it is in the position to form a closure for the cabinet; in which the door will be held against swinging movement while it is being drawn into or out of the cabinet body; in which the door cannot be swung into position to form a closure for the cabinet body until it has been fully withdrawn from the interior of the cabinet bod in which the upper and lower edges which is capable of being attached to the ordinary cabinet body without any change in the appearance or construction thereof.

The invention consists in the features of.

construction and combination of parts here.- lnafter described and claimed.

In the drawings, Figure 1 is a vertical sec-- 7 body; Fig. 5, a plan view of the parts shown swung into position to form a closure for the cabinet; Fig. 7, a section on line 7-7 of Fig. 6, showing the actuating mechanism in elevation; Fig. 8, a modified construction of the rack and pinion shown in Fig. 3; and Fig. 9, a cross section through the plate shown in Fig. 8.

The cabinet body consists of side walls 9, a rear wall 10, a top wall 11,- and a bottom wall 12, all constructed in the manner ordinarily employed in manufacturing cabinet bodies. Positionedadjacent to the top. wall 11 and the bottom wall 12, and secured to one of the side walls 9, are plates 13 and 14,

preferably of angle-iron formation. Each' Patented June 21, 1910.

16, and this toothed edge constitutes, in

effect, a rack; and meshing with the teeth of these racks are

pinions

17 and 18 which are mounted on a rod 19, which has its ends journaled within

plates

20 and 21. These plates are also preferably of angle-iron formation and are secured to a section 22 of a cabinet door 23, which section is capable of a movement parallel only with the side walls of the cabinet body and may be termed the sliding section. The lates13 and 14., as

shown, are of angle-iron or'mation and have one of their extending portions formed as above described to constitute racks, the other projecting portion 24 forming a trackway upon which

travel companion rollers

25 and 26 carried by the plates 20and 21.

Attachedto the section 22 of the cabinet door is a cable 27, which passes over, an idler 28 jou'rnaled in the side wall 9 and positioneduadjaoent to the rear wall 10 ofwhich cable has a weight.

the cabinet body, 29 secured to its end.

The cabinet door is composed ofthe section 22, which has been termed the sliding section, and a section 30, which is capable of movement parallel with the sides of the cabinet body, and is also capable of a swinging movement which will bring it into position to form a closure for the cabinet body, and this section may be termed the swinging sectioazn The two sections are hinged toand well known type of construction. Lo

3 cated near the path of travel ofthe section stop member would act to is a stop member 32 which is secured to the cabinet body and which prevents the door for swinging while it is being moved in or out therefrom. By referring to Fig. 5, where this stop member is shown more in detail, it will be seen that with the parts as shown in this figure, the section 30 of the cabinet door is in position to be swung at right angles to the section 22 and form a closure for the cabinet; but if the parts were in a positiom so that the hinges 31 would lie on the o posite side of the stop member 32, it won (1 then be seen that the revent any swinging movement of the section 30; thus no swinging movement of the section 30 is possible until the section has been fully drawn out from the interior of the cabinet, and no movement tending to draw the door into the interior of the cabinet is. possible until the section 30 has swung into the posit-ion parallel with the sides of the cabinet body, because not before it has reached such posltion will it be able to pass by the stop member. When the section 30 is swung into position to form a closure for the cabinet body, it is desirable that some locking means be em loyed for retaining the section in such position. The locking'meansshown in Figs. 6 and 7, for accomplishing this pur ose, consists of an actuating member 33 hel normall outward under spring tension, and attache" to the actuating member isa bell crank lever 34 connected to the locking member 35. -By referring to Fig. 7, it will be seen that a push inward upon theactuatmg member 33 will cause the bell crank lever 3 1 to assume a position which will retract .the locking member 35' from engagement with a recess 36 formed in the section 30, allowing, said section to swing into position to bedrawn into the interior of the cabinet body. As shown in Fig. 5, one edge of the cabinet body is cut away at 37, forming an overhanging led e 38, which acts as a sto against which t e .door rests when it. 1s swung into position to form a closure for the cabinet.

In Fig. 8 is shown a modified construction, which consists of a rack formed with a plurality of holes 39 in place of the gear teeth 16; and in place of

thepinions

17 and 18 is shown a toothed wheel 40, the formation of the-teeth 41 being such as to adapt them to enter the holes 39 in thestra'ckway.

The operation is as follows: Whenthe operator releases'the mechanism shown in Fig. 7, the spring hinges 31 will act to swing the section 30 into the position showndn Fi s. 1 and 2. When'the section has reached suc positionkitwill then be clear of the stop member, and the tension produced by the weight 29 will cause the sliding and swingin" sections to be pulled into the interior o the cabinet body, the sections being A guided in their rhovements in and out of the cabinet body by the

pinions

17 and 18 and by the

rollers

25 and 26. All of these movements necessary to the positioning of the door within thecabinet body are accomplished automatically, the only action on the part ofthe operator being the moving of the actuating member 33 to release the locking mechanism. The stop member 32 forms means whereby the door cannot be drawn into the interior of the cabinet until it has which course of travel would cause a bind-' ing between the door and the trackway u on which it slides, thus making the door difficult of operation.
