CAR-S EAT. I

SPECIFICATION forming part of Letters Patent No. 623,256, dated April 18, 1899.

Application filed June 20, 1898. SerialNo. 683.945. (No model.)

To rtZ/I 1072 0127. it may concern:

Be it k nown that I, WILLIAM M. Noaonoss, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Oar-Seats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to carseats, and more especially to that class wherein the backsection is supported by swinging arms, by means of which it may be bodily swung or turned over from side to side of the seat-section and at the same time tip or incline the latter.

The object of the invention is to provide a simple, durable, and effective construction in which the supportingarms shall be automatically operated to effect the easy and uniform adjustment of the back.

The invention, as generally stated, consists in the combination, with the frame and the back, of a pair of swinging arms arranged edge to edge, or substantially so, pivotal connections between said arms and the back, and cam connections between said arms and the frame.

The invention also comprises novel features of construction and organization of parts, which will be hereinafter described and claimed.

In the drawings, Figure 1 is a transverse vertical section of my improved car-seat, the seat and back sections being indicated in dotted lines. Fig. 2 is a similar section showing the supporting-arms and back midway of their two positions of adjustment, the rocker and guide-plate being removed. Fig. 2, is a transverse sectionthrough said arms, as 011 the line m x'of Fig. 2. Fig. 3 is a view of the inner side of one of the end supporting members. Fig. 4 is a transverse horizontal section, as on the line y y of Fig. 2, including a part of the rocker. Fig. 5 is an elevation of said rocker. Fig. 6 is an illustration of a slight modification of the supportingarms.

Numeral 1 designates an end frame for the support of the outer end of the seat, the in-. ner end thereof being usually sustained on the side wall of the car. This frame may be of any appropriate construction and configuration, and, if desired, one may be arranged at each end of the seat. On the end frame and on the opposite supporting part (whether it be a wall or frame) are formed or secured transverse members 2, provided on their inner sides with suitably'disposed sockets or casings 6' for the reception and retention of the ends of longitudinal supporting rails or bars 6. On these members are mounted the usual rockers 3, that sustain the seat-section i, such rockers comprising slides with oppositelybeveled or inclined portions 5, that bear upon the fixed casings or supports 6 on the frame, whereby when the rockers are slid to and fro they, together with the seat-section, are correspondingly tilted or inclined. The rockers are actuated by and during the adjustment of the back-section 7, as below explained. This section is provided on its ends, at or about the center thereof, with metallic plates or wings 8, to each of which are pivoted, one above the other, the upper ends of two parallel arms 9 9, the lower ends whereof are freely conlaterally-projecting pins 11 11, that register with the camways, respectively, whereby steady and uniform longitudinal movements are imparted to the arms under the circumstances stated, the studs abutting against the opposing ends of the camways to limit the throw or angle of the arms in respect to the sides of the seat. Preferably the arms of each pair are arranged edge to edge, the contiguous edges being connected by an overlapping tongue and groove 12 or the like,

which permits their reverse longitudinal movements, yet maintains them together.

The upper ends of the arms are pivotally connected with the back plate by pin-andslot connections 13, whereby as the arms are swung to and fro, as above mentioned, the back-section will be turned about or inverted,

IOO

thereby presenting the same side of the back to the seat irrespective of the adjustment. On the inner sides of the supporting members are preferably formed or secured inclined ledges 14, upon which the arms rest and are supported when the back has been adjusted.

It will of course be understood that if the adjacent edges of the arms be unconnected an ordinary pivotal pin connection of the arms with the back will suffice, as in that case the arms will open and close during the swinging thereof from side to side of the seat. (See Fig. 6.)

Secured to the ledges on each frame member is a plate 15, which serves not only to maintain the arms in place and guide them in their movements, but also to prevent the seat-cushion from coming into contact with and being damaged by the swinging arms.

The seat-rockers 3 are provided with parallel vertical ways 16, with which are engaged lateral studs 17 at or near the lower ends of the arms, so that as the arms are swung to and fro the rockers will be reciprocated to effect the requisite tipping or inclining of the seatsection. These rockers are preferably provided with upwardly-projectin g lugs l8,which take against the inner faces of the plates and coact therewith to guide the rockers.

I claim- 1. In a car-seat, the combination, with the frame and the back, of a pair of swinging arms pivotally connected at their upper ends with said back, a camway insaid frame, and connections between said camway and the arms, whereby said arms, as they are swung from side to side of the seat, are reciprocated longitudinally in opposite directions.

2. In a car-seat, the combination with the frame and the back, of a pair of swinging arms pivotally connected at their upper ends with said back,reverse camways in said frame, and connections between each of said arms and the respective camways.

3. In a car-seat, the combination, with the frame and the back, of a pair of swinging arms pivotally connected at their upper ends with said back, reverse cam ways in said frame closed at their respective ends, and lateral studs or projections on said arms registering with said camways.

4. In a car-seat, the combination, with the frame and the back, of a pair ofswinging arms pivoted at their upper ends to said back in different horizontal planes, a camway in said frame, and connections between said camway and the arms, whereby said back is inverted when it is swung from side to side of the seat. 7

5. In a car-seat, the combination, with the frame and the back, of a pair of swinging arms pivotally connected at their upper ends to said back in different horizontal planes, camways in said frame, lateral studs or projections on said arms registering with said camway, and a guide-plate covering the lower portions of said arms.

6. In a car-seat, the combination, with the. frame and the back, of a pair of swinging arms pivotall y connected at their upper ends to said back in difierent horizontal planes, reverse camways in said frame, lateral studs or projections on said arms registering with said camways, and oppositely-inclined ledges or abutments on said frame in the path of the arms.

7. In a car-seat, the combination, with the frame and the back, of a pair of swinging arms having a sliding edge-to-edge connection, a sliding pivotal connection between said arms and the back, and a cam connection between said arms and the frame.

8. In a car-seat, the combination with the frame and the back, of a pair of swinging arms having a-sliding edge-to-edge connection, pin-and-slot connections between said arms and the back, reverse camways on the frame,and connections between said arms and the camways.

9. In a car-seat, the combination, with the frame and-the back, of a pair of swinging arms arranged edge to edge and pivoted at their upper ends to said back in difierent horizontal planes, and a cam connection between said arms and the frame, whereby said arms are longitudinally reciprocated in opposite directions as the back is swung from side to side of the seat, thereby inverting the back.

10. In a car-seat, the combination with the frame, the rocker, and its supports, of a pair of arms, the upper ends of which are pivoted to said back in different horizontal planes, a cam connection between said arms and the frame, and connections between said arms and the rocker.

In testimony whereof I have hereunto affixed my signature in the presence of two sub- IOO . scribing witnesses.
