. necessity of manipulating a device to raise and lower the mattress supporting means of the extensible section of the bed as is necessary with many of the day beds now on the market.

Another object is to provide a day bed of the type which is so constructed that the springs used to assist in the movement of the extensible section will not exert pressu're on either section of the bed in such a way as to tend to tilt or cook up said sections, thereby producing a day bed in which the legs of both. sections will. bear squarely and evenly on the floor when the bed is open, and the extensible section will assume a perfectly horizontal position and will bear evenly on the stationary section when the bed is closed. Other objects and desirable features of my invention will be hereinafter pointed out. I V Figure 1 of the drawings is a perspective view of a day bed constructed in accordance with my invention, showing the bed open, a portion of one of the end pieces being broken away so as to more clearly illustrate the construction of the operating mechanism for the extensible section; and

Figure 2 is an end View of the bed, partl broken away, showing the bed close-n, namely, with the extensible section. super imposed upon the stationary section,

Referring to the dra'win s which illu trate the preferred form 0' my invention, A designates the two end pieces of my im proved day bed, B designates the stationary section of the bed and C designates the extensible section, the end pieces A-being of any preferred design and being connected in any suitable way to the stationary section B, as, for'example, by means of headed pins 1 on the ends of said stationary section that fit in slotted plates on said end pieces A. Each of the sections B and G of the bed is provided with a mattress supporting means, not shown, which may consist ofcoiled springs, air "oven Wire fabric or a linked structure, and each of said sections comprises a rigid frame which may be of any referred construction. In the bed herein illustrated the frame of the stationary section B is provided with upweirdly-projecting end members 2 whose top portions extend transverssl of the end pieces A of the bed and the same of the extensible section U is also provided with upwardly-projecting end members 3 which are so arranged with relation to the end members 2 of the stationary section B that they will be in longitudinal alignment with same when thebed is open and will be in vertical alignment with said end members 2 when the bed is closed. -When the bed is closed, as shown in Figure 2, the extensible section C is arranged in superimosed relation with the stationary section and is supported firmly by the end members 2 of said stationary section, and when the bed is open, as shown in Figure l, the extensible section is positioned in front of the stationary section and lies in the same horizontal plane as said stationary section, The operating mechanism for moving the extensible section G into and out of superimposed relation with the stationary section B is composed preferably of two swinging guide links 4;- carried by the stationary section and laying their upper ends pivotally connected at 5 to the end members 3 of the extensible section, two rockable actuating levers 6 carried by the-stationary section and having their 11 per ends pivotally connected at 7 to the en s of said extensible section, and two contractile springs 8 connected at their rear ends to the upwardly-projecting end members 2 of the stationary section and connected at their front ends to cranks or angularly-disposed arms 9 on the actuating levers 6. The guide links 4 are preferably integrally connected to a horizontally-disposed rock shaft i that is journaled in bearings i arranged on the underside of the frame of the stationary section B, and said links are of such length that when the extensible section is closed, as shown in Figure 2, they will be arranv d in a rearwardly-inclined position, and w en said extensible section is open, as shown in Til Figure 1, they will'be arranged in a forwardly-inclined position. The actuating levers 6 are pivotally mounted on the stationary section B at points infront of and in a higher horizontal plane than the pivotal connections between the stationary section and the lower ends of the guide links 4, and the upper ends of said actuating levers 6 are ivotally connected to the extensible section B at points in front of and in a lower horizontal plane than the pivotal connections 5 between the upper ends of the guide links 4 and the extensible section C of the bed. While it is immaterial how the actuating levers 6 are amounted on the stationary section B, I prefer to provide each of said levers with a horizontallydisposed portion, designated by the reference character 6* in Figure 1, that is journaled in a pair of spaced bearing members 10 on the stationary section B, thereby insuring a free and even movement of the levers 6. The purpose of connecting the guide links 4 together by a rock shaft 4 is to insure said links moving in unison, and thus prevent the operating mechanism of the extensible section from binding in the event the person who is opening or closin the bed grasps the extensible section 5 adjacent one end of same instead of at the middle.

When the bed is closed the springs 8 are under tension. Consequently, all that is required to open the bed is to exert a slight I upward pull on the front end of the extensible section C, so as to permit the springs- 8 to exert a pull on the crank arms 9 of the actuating levers 6, in a direction to cause said levers to rock upwardly and forwardly, and thusmove the section C forwardly and downwardly into its open position in front of the stationary section B. During this movement of the section C, "the links 4 guide said section and hold it in a substantially horizontal position, and when the actuating levers 6 are rocking into their forwardly inclined position, the crank arms 9 on said levers travel past center, and thus restore the tension on the springs 8, thereby causing said springs to be in readiness to swing the levers 6 rearwardly when the front side of the extensible section is lifted during the operation of moving said exi asaeai ment with the end members 2 of the stationary section B. In order that the end members 3 will clear the end members 2 during the operation of moving the extensible section C into and out of its closed position, the members 3 of said extensible section are cut away at their rear ends or provided with inclined'rear ends 3, as shown in Figure 2. Preferably, the stationary section B is mounted on the end pieces A of the bed in such a manner that the le s 11 at the front side of the extensible section C will extend substantially flush with the frontsides of the end pieces A when said extensible section is in its closed position, as shown in Fi 'ure 2.

wing to the fact that the guide links '4 are pivotally connected to the stationary section B at points below and to the rear of the axis of movement of the rock levers 6 and are pivotally connected to the extensible section C at points above and to the rear of the pivotal connections between the rock levers 6 and the section 0, there is no tendency for the sections B and C to cook up or assume a slightly angular position relatively to each other, either when the bed is open or when it is closed. When the bed is closed, the links 4 exert a downward pull on the rear ends of the members 3 of the extensible section, thus holding said ex i tensible section firmly down upon the stationary section B, and when the bed is open, the links 4 also exert a downward pull on the members 3 and prevent the rear ends of said members from moving upwardly relatively to the end members 2 of the stationary section B against which they, abut. In fact, it is impossible to raise the rear side of the extensible section when said section is in either its closed position or open position without first lifting the front side of said section, due to the fact that the links 4: counteract the tendency of the springs 8 to rock the levers 6.

A day bed of the construction above described has many features that make it a decided improvement on the various types and kinds of day beds now on the market: I

1st. It is not equipped with'a lever or other actuating device that has to be operated to raise and lower the mattress supporting means of the extensible section during the operation of opening and closing the bed;

2nd. It is composed of only a few rugged arts of simple design that can be manu 'actured at a low cost and which are not apt to get out of order when the bed is in use;

3rd. The extensible section is mounted in such a way that it can be moved into and out of its closed position by a very slight upward pressure applied to the front side 0 the extensible section at any point along the entire length of same; and

4th. It is equipped with a spring-actuated operating mechanism for the extensible section which is of such construction that there is no tendency for the two sections of the bed to assume a slightly angular position with relation to each other when the bed is open or when it is closed, thereby producing a day bed in which both sections of same will rest squarely on the floor when the bed is open, and the extensible section .will assume a perfectly horizontal position and bear evenly upon the stationary section when the bed is closed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
