REVERSIBLE SEAT FOR TEAM-SAKS AND OTHER PURPOSES.

mea re.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed. January 29, 1914. Serial No. 815,202.

T all whom it may concern Be it known that 1, JOHN EDWARD ANGER, a citizen of the United States of America, residing at Preston, in the county of Lan- D caster, in the Kingdom of England, have invented certain new and useful Improvements in Reversible Seats for'Tram-Cars and other Purposes, of which the following is a specification.

This invention has reference to reversible seats wherein the seat member is of the type which is carried by rockersco-acting with the inclined upper faces of sills extending between the side frames so that upon the movement of the said rockers in either direction the said rockers and the seat member carried thereby will be both moved forward and canted into a convenient slope for the sitter, and wherein the seat back is of the type which is supported by substantially parallel links, the lower ends whereof operate the rockers upon the reversal of the seat back from one position to another.

The invention which is an improvement in or modification of that described and claimed in my prior application Serial No. 797,81 .1- filed October 28, 1913 has for its object to facilitate the assemblage and dis mantling of the parts, whether in the original manufacture or in repairing.

In the drawings Figure 1 is a perspective view of a complete seat made in accordance with my invention but with the seat member removed, Fig. 2 is a side view of the tilting mechanism and Fig. 3 is a plan view thereof.

1 are the rockers for the seat member adjacent to each of the side frames 2, and 3 -t the sills which extend between the side frames.

5 6 are the inclines on the underside of each rocker at the ends, which co-act with the inclined upper faces of the sills 3 1 so as to tilt the rockers when they are moved longitudinally by the swinging over of the seat back.

7 is the toothed rack located between the inclines 5 6 on the underside of each rocker, and 8 9 are the guides secured to the respective sills which cooperate with the flanges at each side of the inclines 5 6 so as to hold the rockers securely against lateral displacement also prevent them being lifted off the sills, while guiding them in arrangement.

11 and 12 are the substantially parallel links which support the seat back 13, these links being mounted at their lower ends upon cross shafts, and are arranged when the seat back is swung over to turn the toothed pinions 11 15 which gear with the racks 7 on the rockers 1 and so slide the rockers in the direction of their length. These links 11, 12 hold the back at a convenient slope for the sitter with the arms 11 (for the time being underneath) supported by rests 16, or when the back is swung over, the other arms 12 are brought against the opposite rests 17.

So far as the seat has been described, it is shown in my application for Letters Patent, Serial No. 7797,81 1, filed October 28, 1913, and it is shown and described in the present application for the purpose of explaining my present improvements.

The cross shaft 18 which carries the fast pinion 141-, extends between and is journaled in the side frames 2 as in my said prior application but according to my present improvement the pinions 15 which co-act with the rocker racks 7, are mounted freely on stub shafts or pins 19 formed integral with, or secured to, the side frames 2 on their inner sides. These stub shafts 19 are located in line with each other but extend only part way between the side frames, being stopped off just beyond the pinions 15. At their free ends, the said stub shafts 19 are coupled to the cross shaft 18 by means of links 20 for the purpose of retaining the said stub shafts 19 in parallelism with the cross shaft 18. These links 20 each have at their ends, eyes bored out to fit freely onto the respective shafts 18 and 19, and the said links are kept in position by pins or cotters 21 passing through the eyes and through the stub shafts 19, or by any other suitable Each link 12 has a boss 22 which is fixedly secured to the cross shaft 18, and each link 11 has a boss 23 which is freely mounted on its respective stub shaft 19, while the pinions 15 which are mounted freely on the stub shafts 19, gear with the racks 7, and with the pinions 1 1 which are keyed to the cross shaft 18. Therefore the swinging over of the seat back turns the cross shaft 18, and this shaft by means of its inions 1& turn the free pinions 15 and so slide the rockers 1 and tilt the seat member to the required inclination.

The advantage of the arrangement is that the assemblage and dismantling of the parts.

is facilitated. For instance the pinions 15 if broken or worn, can be readily removed, it being only necessary to take out the cot ters 21, slide the links 20 along the shafts 18 clear of the shaft 19, whereupon the pinions 15 can be taken off and new pinions can be passed on 'to the shaft 19, without disturbing the rockers l at all. The same takes place should the rockers 1 want removing, and replacing. The racks being on the underside of rockers 1, act above pinions 15, and when pinions 15 are removed from shafts 19, rockers 1 can he slid back out of the guides 8 and 9 and replaced by new ones. By increasing or decreasing the diameter of the pinions 15 which operate the rockers l, a greater or less travel can be given to the rockers, as may be required.

In my prior specification it was easy enough to renew the rockers 1 if broken, but to remove the pinions 15 it was necessary to dismantle the whole seat, The present im provement avoids this disadvantage, and the links 20 insure that the shafts 19 cannot be sprung away from or out of parallelism with the shaft 18, thus insuring that the pinions shall co-act. V

' I declare what I claim is 1. A reversible seat of the type referred to, comprising in combination side frames, sills extending between the side frames, rockers for supporting the seat member hav ing inclined under faces at their ends resting upon inclined upper faces of the sills, toothed racks on the underside of the rockers between the said inclines, stub shafts formed integral with or secured to the side frames, and pinions or' toothed segments mounted freely on said stub shafts so as to co-act with the racks on the rockers, whereby such pinions or segments can be readily reers between the said inclines, a cross shaft.

extending between and journaled in the side frames and carrying pinions or toothed segments, a stub shaft formed integral with or secured to each side frame, pinions or toothed segments mounted freely on the said stub shafts and adapted to co-act with the racks and the other pinions.

3. A reversible seat of the type referred to, comprising sills extending rockers for supporting the seat member having inclined under faces at their ends rest ing upon inclined upperfaces of the sills, toothed racks on the under side of the rockers between the said inclines, a cross shaft extending between and journaled in the side frames and carrying pinions or toothed segin combination side frames, between the side frames,-

ments, a stub shaft formed integral with or I secured to each side frame, pinions or toothed segments mounted freely on the said stub shafts and adapted to co-act'with the racks and the other pinions, and links for coupling the free ends of the stub shafts to the cross shaft for the purpose of retaining the said stub shafts in parallelism with the cross shaft. 7

In witness whereof I have hereunto signed y name this 16th day of January 1914, in the presence of two subscribingwitnesses.
