T t v 1 For a full understanding ofrthe invention a detailed description of a construction embodying all the feat-uresof. vthe s'ame will now be given in connection'with the accompanying drawings, showing all'the features of the invention as applied in/their preferred form, and the features forming the invention will then. be specifically pointed out in the claims.

In the drawings, Figure 1 is a vertical cross-section of the seat, taken inside the frame; 'Fig. 2is a rearview of the seat as shown inFig; 1, with the frame'cutaway on one side to show the construction." .Fig. 3 is a view similar to Fig. 1, showing infull lines the seat reversed from the position shown in Fig. 1 and in dotted lines the position of the back and foot-rest in central position during reversal. Figs. 4 and 5 are; detail enlarged views showing-two positions of the. foot-rest and actuating extensions of the back-shifting arms in reversing from the positionshown in Fig'. 1 to that shown in Fig, 3. .Fig. 6 is an enlarged detail section showing a lock that mayb'eusedv :f-

C is the shiftable seat-back v "ersing-arms by which the seat-back is carried and reversed. E is the seat-cushion, pro- D .D', the re- I vided with the inclined seat-support F, moving upon the inclined seat-sup 'orting bars G,

so as to rock the-seat to secure the desired inclination as it is moved toand fro during the reversal of the back. This construction of sh iftable seat-back,reversing-arms,andshift- 'ing seat is the same as that of my Patent No.

542,411, above referred to, and will be understood from said patent without a detailed description or illustration herein, the r03 ersingarms .D- D being mounted 'on the frame at their lower ends by pivots I and pivoted to the seat-back at theirupper ends by pivots. 2, as shown in dotted lines in Fig.1,beneath the cap as. One of the pivots. 2' may be in the r cap a: and the other directly on'theseat-back IOC I C, as described in Patent No. 512,411,01' the upper. ends of both arms may be pivoted directly to the seat-back, as shown and described in Patent No. 542,398. The back-reversing arms are thus pivoted to the seat frame and back on opposite sides of the vertical center, and, as shown, the portions of said arms between the seat and back lie in parallel planes and overlap each other and are of such width as to avoid separation at their inner edges during the reversing operation, being preferably of equal width, as shown, so as to have the appearance of a single arm in both positions of the seat, and the arms D D" are provided, respectively, with stops a a on opposite sides of the line of intersection of the arms, so that each arm by 'these stops acts to arrest the movement of and support the other, a self-supportin g back and back-reversing arm construction thus beingprovided. Theseat-cushionEisshifted sidewise as the back is shifted by the pin e entering the slotf, formed in the cushionframe F, this pin e being carried by a lever actuatedby the arms D D, asfully described hereinafter.

The present invention relates to the construction of the foot-rest and those parts of the reversing-arms D D by which the footrest is actuated, the object of the invention being to provide an etiicient and durable construction of foot-rest, avoiding any looseness or play of the parts and with the foot-rest moving easily and smoothly from one side of the seat to the other in reversing the back and held in position for use firmly and in such a manner as to support the foot-pressure of the user without any strain upon the backreversing arms tending to shift or shake the back, so as not to disturb the occupant of the seat. I secure this result by the improved construction shown, as follows:

The reversing-arms D D are provided with extensions d (1 below the'pivots 1, which engage the heads h on the upper ends of footrest-actuatin g levers H, which arepivoted at fixed points on the seat-frame A, as in Letters Patent No. 542,411, above referred to, except that the arrangement of the levers II relatively to the extensions (Z d and the form of the heads and extensions are changed. These levers H preferably form in themselves the s ngle side bars of the foot-rest and carry the single rest-bar i, as shown, and may be mounted in the frame A in any suitable manner; but the construction shown is preferred, in which they are secured together and stayed by sleeve 12, which is mounted upon a'shaft 13, extending between and secured in the end frames, so that a long bearing for the foot-rest is thus provided, assuring a strong and durable construction and smooth movement. The shaft 13 also serves as a tie and stay for the two stands A forming the end frames of the seat.

' Referring now to the arrangement and form of the heads h and extensions (1 (1, these are so formed and arranged relatively to each other and to the pivots 1 of the reversing-arms D D and the pivots 13 of the levers H that the foot-pressure upon the rest-bar 'i, transmitted through the levers II and the heads h, is supported by the extensions (Z or d in contact therewith in a direction substantially radial to the are of swinging movement of the extension as the arm D or D is swung upon its pivot 1 in reversing the back, so that this pressure upon the foot-rest is supported directly by the pivots 1 and has no tendency to swing or shake the back 0. The arrangement may be such that the engaging surfaces of the heads h and the extensions d or d are in line with the pivots 1 2 of the arms D or D having the extensions by which the pressure on the head It is then supported; but preferably the arrangement, as shown, will be such that the pivot 1 is slightly outside the line between the pivot 2 and the center of the engaging surface of the extension and head 72, so that the foot-rest and pressure upon it tends to lock the arms D D and back 0 in position when the back is fully reversed in either direction.

As shown in Figs. 1 and 3, in which the two opposite positions of use of the seat and foot-rest are shown, the heads 7t of the levers H are engaged only by the extensions d or d on the rear side of the heads h, which extensions support the pressure upon the foot-rest, and the extensions (2 or d on the front side of the heads 71 are out of contact with the heads h in these positions. There is, therefore, no pressure of the heads it upon the front extensions (1 or d tending to move the latter and thus swing or shake the back, and the free movement of the arms D or D carryin such extensions is thus permitted at the commencement of the reversing movement. As the reversal of the back commences, however, both extensions d and (1 come into contact with the heads h, the levers II swinging as permitted by the movement of the engaging extensions d or d and being held in contact with the engaging extensions by the weight of the foot-rest, so as to move smoothly, and when the other extensions 61 or (1 come into contact with thehead it both sets of extensions d (1 move together and in contact with the heads h on opposite sides, so as to positively and smoothly carry the heads with them as the back is reversed and thus swing the levers II smoothly and uniformly to shift the foot-rest. Toward the end of the movement the extensions (1 d at the front of the seat in its reversed position move out of contact with the heads 71, the latter then being moved and controlled for the balance of the movement by the extensions (Z or cl at the rear of the seat. It is not necessary in this construction to use stops for the foot-rest or arms, as the arms D D are self stopping and supporting, and the weight of the foot-rest -II will prevent overthrow of the foot-rest; but I have shown and preferably use stops 10 in the frame A on op-,

andthe extensions d on the other arms D then come into. contact with the 'headsh, and both extensions then press upon opposite sides of the head by'their heels or inner bearing portions, the heads-k thus being held on both sides and positively moved during the further reversalofthe back until the parts are of Fig. 4'at the opposite side of the seat,--and curved bearing-surface'sB of theextensions d come in contact with the bearing-surfaces d leave the heads h, so asto be out of contact with them-when the foot-rest is broughtinto the-position shown in Fig. 3 by the full reversal of the back. readily understood from ,theijdrawings and It will-be understood that the invention is applicableto seats of other construction and than that shown and that it is not z in brought into a position corresponding to that therein by those skilled in the art while retaining the invention.
