CHAIR.
Specification of Letters Patent.
Patented Oct. 22, 1907.
Application filedDecember 14,1906. Serial No. 347,867.
To all whom it may concern:
Be it known that I, ROYER S. Boon, a citizen of the United States, residing at Elizabethtown, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Chair, of which the following is a specification.
This invention relates to swinging chairs or devices of that general class known as lawn swings.
The principal object of the invention is to provide a chair construction in which a seat and back are pivotally connected to each other and may be readily adjusted to alter their relative angular positions.
A further object of the invention is to provide an adjustable chair of this type in which the chair arms are employed to hold the back and seat members in adjusted position a mi in which the construction is such that on release of the arms the chair and back will automatically move to a :1 initial or predetermined position.
A. still further obj cct of the invention is to provide an adjusting and locking means for chairs of this type which will not in any manner interfere with the freedom of operation of the swing.
With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawingsz-Figure 1 is a perspective view of a lawn swing having chairs made in accordance with the invention. Fig. 2 is a side elevation of one of the chairs drawn to an enlarged scale, the seat and back being shown in one position of adjustment. Fig. 3 is a view similar to Fig. 2, showing the seat and back adjusted to another position. Fig. 4 is a detail perspective view of a portion of an arm or siderail of the chair and one of the holding plates with which the arm engages to lock the back and seat in ad justed position.
Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.
The swing is supported on a frame which includes a number of inclined standards 10 which are connected in pairs at their upper ends by crossed bars 11. Extending from the pairs of standards are arms 12 which are pivotally connected together, and these are held in place by braces or stay rods 13. i
To the outer ends of the bars 12 are hung suspension rods 15, four of such rods being preferably employed,
and these are arranged in pairs, and are connected to a lower foot frame 16 which in the present instance is formed of a pair of bars 17, and a plurality of cross bars 18, the latter generally formed of wood. The distance between the points of connection between the upper ends of the suspension bars and the bars 12 and the distance between the lower ends of the suspension bars is approximately equal, so that the lower foot frame may be considered as swinging on a pair of parallel links, so that said frame will constantly remain in a horizontal position.
Pivoted to the suspension bars 15 are catch plates 19, and these may be adjusted to any desired position, the suspension bars being provided with a plurality of openings 19, into any one of which the connecting pivot of the plate 19 may extend. Each plate 17 is split at one end to form a plurality of ears 20, 21 and 22, of which the ears 20 and 22 have openings for the passage of securing screws or bolts. The ears 20 and 22 are connected rigidly to the metallic bars 23 of the back of the chair, being preferably secured to the rear web thereof, while the ear 21 serves partly as a guide for the side arm of the seat as hereinafter described, the connection between the frame back and the clamp plate being rigid, but the connection between the clamp plate and the suspension bar being pivotal. Pivoted to the lower edge of the back frame 23 is a seat frame 25 which is preferably formed of angle bars at the sides, and cross bars of wood or other material, and the forward edge of said seat frame is pivotally connected to the upper ends of a pair of links 30, the lower ends of which are connected by pivot pins 31 to the side bars of the foot frame,
The pivot pin 32 which serves as a connection between the seat frame and the links 30 carries also the side arm 33 of the chair and the rear end of this side arm is arranged to extend alongside the catch plate 17 in a position between the two ears 20 and 22, said side arm being provided with a plurality of notches 36 which may be locked in engagement with the lug 22 for the purpose of holding the back and seat frames in any angular position with respect to each other. It will be seen that by manipulating the side arms 33, the relative angular positions of the seat and back may be adjusted from the position shown in Fig. 2 to that shown in Fig. 3, or to any angle between these, and when so adjusted the parts may be locked by the engagement of one of the notches 36 with the lug 22. If the parts have been adjusted, say to the position shown in Fig. 3, and it is desired to readjust to the position shown in Fig. 2, it is merely necessary to raise the rear ends of the side arms and the seat and back will move by gravity to the position shown inIig. 2.
The device may be quickly adjusted to any desired position and readily locked in position, while the free swinging movement of the device as a whole is not interfered with.
I claim:
1. In a chair of the type described, suspension rods, a foot frame pivoted thereto, links having their lower ends pivoted to the frame at points in advance of the rod connections, pivotally connected seat and back members, the seat being pivoted to the upper ends of the links and the back being pivoted to the rods, and side arms or rods forming an adjustable connection between the seat and back to permit alteration of the angular relation of said seat and back.
2. In a chair of'the class described, the combination with suspension rods, of a foot frame pivoted thereto, a pair of links having their lower ends pivoted to the frame, a seat member, the forward edge of which is pivoted to the upper ends of the links, catch plates secured to the back and pivotally connected to the suspension rods, and side arm members pivoted at the forward edge of the seat and having means for interlocking with said catch plate.
3. In apparatus of the class described, a pair of suspension rods, a foot frame pivotally connected thereto, a pair of links, the lower ends of which are pivoted to the frame at points in advance of the rods, pivotally connected seat and back members, the forward edge of the seat member being connected to the links, and the back member being pivotally connected to the suspension rods, and a pair of side arms forming an adjustable connection between the links and bars to permit variation in the distance between them and likewise serving to alter the angular position of the seat and back with relation to each other.
4. In a chair of the class described, the combination with a pair of suspension rods, of a foot frame carrying said rods, a pair of links, the lower ends of which are pivotally connected to the frame,-a seat, the forward edge of' which is pivoted to the upper ends of the links, a back member pivoted to the rear edge of the seat, catch plates,
the inner ends of which are split to form a plurality of,.
lugs, means for securing the lugs to the back member, and side arms arranged to extend through the plate and provided with notches for the reception of the upper edge of one of the lugs.
In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
