'WILLIAM M. NORCROSS, OF PHILADELPHIA, PENNSYLVANIA.

CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 623,255, dated April 18, 1899. 7

Application filed January 11,1898. Serial No. 666,288. (No model.)

To all whom it ntay concern:

Be it known that I, WILLIAM M. NORCROSS, 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 Car -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 has relation to reversible car-seats of that class wherein the back-section 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 providea simple, durable, and efiective construction in which the supporting-arms shall swing in parallelism, or substantially so, in'a manner to effect the easy and uniform adjustment of the back and at the same time to lie in contact to avail of their combined strength and rigidity to sustain the back when it has been adjusted.

To this end the invention, as generally stated, consists in the combination, with the frame and the back, of a pair of arms located at each end of the seat and pivotally connected with said frame and back and means whereby the arms are caused to swing in parallelism from side to side of the seat, together with appropriate stops or 'abutments to limit the movement of said arms and support them in their positions of adjustment.

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

In the drawings, Figure l is an end elevation-of a car-seat embodying my invention. Fig. 2 is an elevation of the inner side of the upper portion of the end frame and its connections, the seat and back being indicated in dotted lines. Fig. 3 is a similar view, the parts being shown midway of their two positions of adjustment. Fig. at is a view of the lower portion of 3 with the rocker and guide and guard-plate removed. Fig. 5 is a section, enlarged, as on the line a: mof Fig. 3.

The numeral 1 designates an end frame for the supportof the outer end of the seat, the

inner. end thereof being usually sustained on the side wall of the car. This frame may be of any appropriate construction, 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 orsecured transverse members 2, on which are mounted the usual rockers 3,thatsupport the seat-section 4:,such rock- .ers comprising slides with beveled portions the lower portions whereof are pivotally con-- nected, as at 10, to a link 11, which is in turn centrally pivoted, as at 12, to the member 2.

These arms at points below or adjacent to the link are provided with studs 13, which register with a guideway 14 in the member, such guideway being eccentric in respect to the pivotal center of the link, so as to guide and direct the arms in parallelism as they are swung from side to side of the seat. In this way it will be seen that during movement of the arms back and forth they will slide longitudinally in opposite directions in a manner to move the adjacent upper ends as well as the adjacent lower ends of the bars one above the other alternately, and that therefore the backsection will be turned about or inverted when it is swung from one side to the other of the seat, thereby presenting the same side of the back to the seat irrespective of the adjustmen'r. On the inner sides of the supporting members are formed or secured inclined ledges 15, upon which the arms rest and are supported when the back has been adjusted.

In order still more efiectually to support the arms the lower portion of the guide is cut ICO 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.

By the construction describedit will be seen that the arms may be plane steel bars which require very little fitting or adjustment and that when they are inclined on either side of the seat they bear one upon the other in a manner to insure great strength and rigidity.

The seat-rockers above referred to are recessed to receive the lower portions of the arms, so that as the latter are swung to and fro the rockers will be reciprocated to efiect the requisite tipping or inclining of the seatsection. These rockers are preferably provided with upwardly-projectinglugs 18,which are covered by the plates 17 and coact therewith to guide the rockers.

It will be obvious that any appropriate locking device may be employed to lock the arms, and perforce the back, in the positions of adjustment. In the present instance I have represented for this purpose a sliding pin 19 of usual construction, arranged to register with holes 20 in the link 11 above described.

I clai'm- I 1. In a car-seat, the combination, with the frame and the back, of a pair of parallel swinging arms pivotally connected at their upper ends with said back, pivotal connections between said frame and arms, a guideway in said frame, and connections between the said arms and guideway, whereby the arms, as they are swung back and forth, are maintained in parallelism and reciprocated longitudinally in opposite directions.

2. In a car-seat, the combination, with the frame, and the back, of a pair of arms the upper ends of which are pivoted to said back in difierent horizontal planes, a partiallyrotatable support on said frame, pivotal connections between said arms and support, and a guide for the lower portions of said arms, eccentric in respect to said pivotal connections, substantially as described.

3. In a car-seat, the combination, with the frame, and the back, of arms pivotally connected with said back, in different horizontal planes, a link pivoted to said frame and connected with said arms, a guide for said arms, eccentric in respect to the link connection and connections between said guide and arms, substantially as described.

- 4:. In a car seat, the combination, with the frame, and the back, of arms operatively connected with said back, a partially-rotatable support on said frame, connections between said arms and support, an eccentric guide on said frame, and connections between said arms and guide, substantially as described.

5. In a car-seat, the combination, with the frame and the back, of a pair of arms the upper ends of which are pivoted to said back in different horizontal planes, a partially-rotatable support on said frame, pivotal conin different horizontal planes, oppositely-movable pivot connections between said arms and the frame, whereby said arms are caused to reciprocate longitudinally in opposite directions as they are swung back and forth to in vert the back, and connections between said arms and the frame to guide and steady the arms in their movements, substantially as described.

7. In a car-seat, the combination, with the frame and-the back, of a pair of parallel arms arranged edge to edge and operatively connected with said frame and back, means whereby said arms are caused to swing in parallelism, an eccentric guide for said arms,

and stops or abutments therefor, substantially as described.

8. In a car-seat, the combination, with the frame and the back, of a pair of arms arranged edge to edge throughout their length and pivoted at their upper ends to said back in different horizontal planes,oppositely-movable pivot connections between said arms and the frame, whereby said arms are caused to reciprocate longitudinally in opposite directions as they are swung backand forth to invert the back, connections between the arms and the frame to guide and steady the arms in their movements, and stops or abutments for the lower ends of the arms, substantially as described.

9. In a car-seat, the combination, with the frame and the back, of a pair of arms arranged edge to edge throughout their-length and pivoted at their upper ends to said back in different horizontal planes,oppositely-m ovable pivot connections between said arms and the frame whereby said arms are caused to reciprocate longitudinally in opposite directions as they are swung backand forth to in-' vert the back, connections between the arms and the frame to guide and steady the arms in their movements, and oppositely-inclined ledges or abutments on said frame in the path of the arms, substantially as described.

10. In a car-seat, the combination,'with the frame and the back, of a pair of arms operatively connected with the back, a partiallyrotatable support on said frame, connections between said frame and support, a guide for said arms having an open or cut-away portion, together with shoulders or abutments with which said arms coact, substantially as described.
