HIGH CHAIR.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed March 26, 1913. Serial No. 756.925.

To all whom it may concern Be it known that I, ROY E. PATRICK, a citizen of the United States, residing at Clayton, in the county of Jefferson and tate of New York, have invented new and useful Tmprovements in High Chairs, of which the following is a specification.

This invention is an improved collapsible and convertible high chair and jumper for infants and small children and consists in the construction, combination and arrangement of devices hereinafter described and claimed.

The object of this invention is to provide an improved high chair which may be readily collapsed or folded so as to occupy but little space when not in use and which is also adapted to be used as a baby jumper.

In the accompanying drawings :Figure 1 is a perspective view of my invention, showing the same set up and in position for use as a high chair. Fig. 2 is a longitudinal vertical sectional view of the same in a horizontal positionand arranged for use as a baby jumper. Fig. 3 is a detail transverse sectional view on the plane indicated by the line aa of Fig. 2. Fig. 1 is a side elevation of the convertible high chair and jumper, showing the same in folded or collapsed position.

In the embodiment of my invention, a pair of rear legs 1 are provided, which are of suitable length, arranged in an inclined position to slightly converge toward their upper ends and connected together at points at suitable distances from their lower ends by an upper cross bar or rung 2 and a lower cross bar or rung 3. The back 4 is secured between the upper portions of the legs 1.

The seat 5 has its rear end pivotally connected as at 6 on a cross rod 7 which connects the legs 1 and, hence, the seat is adapted to be folded downwardly against the back 4.- when the chair is collapsed.

The front legs 8 are shorter than the rear legs and are connected together by upper and lower rungs 910 and also by a foot rest 11. A rod 12 connects the front legs together at a point a suitable distance from their upper ends and when the device is set up for use as a high chair, the front end of the seat 5 bears on and is supported by said rod 12.

A tray 13 is provided with a pair of supporting arms 14 which are curved upwardly at their rear ends and pivotally connected to the upper portions of the rear legs 1 by a pivot rod or other suitable device 15. This tray when in lowered position bears on the upper ends of the front legs. The tray with its arms 1 1 may be swung upwardly over and to the rear of the rear legs to arrange the same entirely out of the way when the chair is folded, this being illustrated in Fig. 4.

A rod 16 connects the front legs 8 together and is arranged above the upper rung 9. This rod secures a pair of rearwardly extending arms 17 to the front legs. Pairs of brace bars 18 are pivotally connected at their rear ends to the rear legs 1 by the rod 7 and a rod 19. Each of these brace bars has a longitudinal slot 20. The brace bars converge forwardly, overlap at their front ends and are secured to the arms 17 by thumb screws 21 which operate in the slots 20. By first loosening the thumb screws, the members of the pairs of brace bars may be crossed to permit the front legs to be arranged close to the rear legs in order to collapse or fold the chair and permit the compact arrangement and disposal thereof as shown in Fig. 4, the thumb screws 21 and the slots 20 in which they operate providing slidable connections between the arms 17 and the brace bars 18.

A jumper seat 22 is also provided which has a supporting arm 23 on its rear side and which projects forwardly therefrom. A balancing arm 25 is slidably mounted in the rung 9 and is here shown as comprising a pair of spaced members 26 connected together at their front ends by a filler 27 and rivets or other suitable devices 28. The arm 23 of the jump seat is arranged with its front portion between the members of the balancing arm and is pivotally connected thereto as at 29 so that the arm 23 may be either arranged in line with the balancing arm as shown in Fig. 1 or may be arranged at an angle thereto, as shown in Fig. 2. The pivot 29 operates in a short slot 30 with which the arm 23 is provided and the members of the balancing arm have notches 31 in their upper sides near their rear ends to receive a stud 32 which projects from opposite sides of the arm 23. When said arm is in line with the balancing arm, the stud 32 engages the notches 31. When the arm 23 is at an angle to the balancing arm, the said stud bears on the members of the balancing arm at points to the rear of said notches 31.

A hook 33 has its lower end pivotally connected between the members of the balancing arm as at 3A and the bill of the hook which is at its upper end is adapted to be engaged with the rod 12 which connects the upper portions of the front legs 8. Hence, this hook when the device is used as a jumper serves to support and also form the pivot or fulcrum for the balancing arm and the jump seat.

A coiled retractile spring 35 has its rear end connected by an adjusting screw 37 to a lower rung 3 of the rear legs as at 36 and has its front end connected to the rung 10 of the front legs.

When the chair is in a horizontal position, as shown in Fig. 2 with the tray 18 extended beyond the upper ends of the rear legs and the jump seat with its balancing arm adjusted in the rung 9 and its supporting arm arranged as shown the device is adapted for use as a baby jumper as will. be

readily understood, the seat with its arms 2325, together with the front legs, rocking upon the rod 16 as a pivot, this being permitted by the spring 85. When the device is folded or collapsed and also when used as a high chair the jumper attachment is arranged out of the way between the front legs 8, as clearly indicated in Figs. 1 and 4. The slidable mounting of the arm 25 permits the jump seat to be moved out of the way and arranged below the seat 5.

While I have herein shown and described a preferred embodiment of my invention, I would have it understood that changes may be made in the form, proportion and construction of the several parts without departing from the spirit of my invention and within the scope of the appended claim.

I claim A structure of the class described comprising a base frame, a rocking frame, pairs of brace arms pivotally connected to the base frame and provided with longitudinal slots, said brace arms converging in one direction, being arranged in overlapping position, and extending toward the rocking frame, rearwardly extending arms secured to the rocking frame, thumb screws pivotally connecting said arms to the brace. arms and adjustable in the slots of the latter thus permitting the rocking frame to be folded against or spaced from the base frame and pivotally supported, a jump seat connected to, movable with the rocking frame and extending beyond one end of the rocking frame, and a spring connecting the opposite end portions of the base and rocking frames together.

In testimony whereof I aflix my signature in presence of two witnesses.
