Patented Dec. is, is'aa p, me, w Mrs f w t-* w mr ROCKING CHAIR.

Application filed August 2'5, 1922. Serial No, 584,594.

To all whom it may omelet an.

Be it known that I, Hermann SorroPs, a citizen of Germany, and residing at Unstrutstrasse, 1, Neukolln, Berlin, Germany, have invented a new and useful improvement in a Rocking Ghair, of which the following is a full, clear, and exact specification, reference being had therein to the accompanying drawing.

The invention relates to a rocking chair, the seatof which rests upon a support in such a manner as topermit of being easily swung and which with the help of a lever arrangement connected with the supporting frame can be easily set into swinging motion. The person seated on the chair can without eil'ort merely by movement of the foot, bring the chair to rock backwards and forwards and on the other hand by leaning forward and at the same time drawing in the legs cause an immediate cessation of the motion, for instance, for purpose of leaving the chair.

On account of the easy motion of the rocking chair it is possible to connect appliances causing a motion of the air with the same, so that at the same time a cooling effect is produced, which renders the use or this chair in warm seasons and in the Tropics,eto., par ticularly agreeable.

In order to adapt the chair for ready use by persons of various sizes, the point of contact of the chair seatwith the supporting point is adjustable by ineans'ot a simple gearing, so that the person seated on the chair can himself by a simple turn of the crank adjust the position of the chair in accordance with his size. After corresponding adjustment, the slightest change in the position of the legs causes a change n the position 01 the seat or a swinging of the chair, thus producing the pleasant r cking movement. In every position or" the supporting point, which for practical purposes should be movable upon rollers. the chair can be completely tilted backwards to serve as full length resting chair, or it can he raised to serve as a sitting chair- It the chair is completely tilted hacls wards the lower part of the legs and the knees are stretched out and are supported by the foot rests so that the legs also can he brought into a resting position. It a person lying in this position desires to quickly leave the chair, it is not necessary to turn back the supporting point, since the chair, due to the lever arrangement in conthis invention is shown in the drawing in which Fig. 1 is a side elevation of a simple chair without moving device swung to the rear,

Fig. 2 a side elevation of the chair frame, with moving device, in sitting position,

Fig. 3 the same vi'ewwith another adjustment, i

Fig. 4 a section on the line IV.-IV of the chair Fig. 2, i i

'The rocking chair frame a rests upon supporting rollers Z) of the rigid frame 0, provided on both sides of the chair. The foot rest catches in the cogs g of the cranked lever d? and is therefore adjustable according to the size of the person using the same. The crank lever cl, d swings on an axis al which lies in the chair frame a and is connectedwith a guide 6, which turns on the axis 6 if a person sitting in the rocking chair swings the hinged rods (Z, 6, by means of the foot rest f, the frame a is brought into the position shown in Fig. 1. Just as easily as the backward swinging motion is possible, a return swing can again be produced by pressure of the lower legs upon the lever d For adjustment of the supporting position to the person using the chair, a movement of the seat upon the support is necessary. For this purpose the seat has a cogwheel k with crank Z, by the turning of which the sector rack h and simultaneously the axle h? is turned. With the arms of the sector rack 71. a rod 2' is connected, which swings upon rigid point on the frame 0. By turning the cog wheel hv therefore, the chair frame a is moved on the rollers Z) and the rocking motion transferred to the person seated in the chair By means of the sector rack h, as indicated in Fig. 4, the'movement of the same is transferred to the other side of the chair where a corresponding lever Z takes effect. It is therefore only necessary to turn first to be swung n opposition to the pressure of the spring Z? around the peg Z so that the pin Z emerges from'the catch opening. Now the ha-ndlefis turned until the proper centre of gravity for the chair frame a-is obtained, whereupon the pin Z is allowed to spring into the next opening m.

An extension wall u with blind-like openings is provided in the back rest of the framed, which former-bears a frame consisting of cane or other light material and covered with canvas gauze or other light fabric. This frame consists of four flat parts. a, .0 and n 0,'which come into contact with one another upon a cross bar 1"; but the frame has anopening at. its lower end on the rightl and left of this cross bar which in each case is provided with a short wall 7?, t i .in easily movable disc 3 is provided on the cross bar 9", the former, when in motion, strikingin the one casethe wall If and in the other case the wall 3 With the movement of the rocking chair the air penetrates alternately into the spaces 10 or w and also passes through the openings or qto the person seated in the chair. By means of -thel disc's the entrace tothe opposite spaces is obstructed in each case, so that the air is always compelled by the guidance of the canal caused between t or t and the disc 8, to discharge in the direction towards the person seated. When the chair moves forward in rocking the air penetrates through the space to and passes through the canal q to the person seated. When the the person seated.

chair is in backward motion the air penetrates through the space w, throws back the discs to obstruct the canal between 8 and t, and passes through the opening 9' to If the rocking chair is at rest, an air current can be produced through the blind opening in the connecting wall 9.

After thus having more fully described and ascertained the nature of my invention and in what manner the same is to be performed I declare that what I claim is:

1. A swing chair comprising seat, back and arm portions, a bell crank lever pivotally connected to the forward portion of said seat; a basefor said chair having an upright rigidly securedthereto at one end,

a second upright pivotally connected at its lower end thereto forwardly of said rigid upright and at its upper end pivotally connected with said bell crank, a roller secured to the free end of said rigid upright upon which said chair arm is adapted to move when pressure is applied to said bell crank.

2. A swing chair comprising seat, back, and arm portions, a. bell crank lever pivotally connected to the forward portion of said seat: a base for said chair having an upright rigidly secured thereto at one end a second upright pivotal-1y connected at its lower end thereto forwardly of said rigid upright and at its upper end pivotally connected with said bell crank, a roller secured to the free end of said rigid upright upon which said chair arm is adapted to movewhen pressure is applied to said bell crank, arcuate segmental rack pivoted to said seat alink connecting said. rack and the upper end of said rigid upright and a gear having a crank secured to said arm and operatively engaging said rack for swingirgly operating said chair.

In testimony whereof I have signed my HERMANN SCHOPS.
