Abstract: 1608. Powell, G. H. Jan. 22. Perambulators. - A perambulator is constructed so that it can fold into a box resembling a suit case, the parts being automatically extended or collapsed as the box, which forms part of the perambulator frame, is opened or closed. The suit case consists of two sections 1, 2, connected together at one end by hinge bars 3 pivoted at 4 and 5, and capable of being locked in their open and closed positions by means of a slotted link 6 and a turn-button 8 at the other end. Pivoted to supports 12 at the front of the section 1 are two seat bars 9 from which are suspended a seat 10 and a seat back 25. Pivoted to the bars 9 at 14 is a supporting-frame 15, preferably provided with rollers 16 at its lower end, which is moved so as to raise or lower the seat by means of links 22 connecting the frame 15 to handle-bars 18 pivoted to supports 20. The supports 20 have lugs 21 to limit the backward swing of the bars 18; to accommodate the bars 18 when folded, the supports 12 extend inwards so as to leave a space between the bars 9 and the sides of the section 1. Two wheel-carrying frames, each having an horizontal portion 31 and two inclined end portions 32, are pivoted at 33 to supports 35, 36, which extend across the section 2. The wheel supports are locked in their open position by locking-frames 39, 40, connected at their lower ends by integral twisted portions 45, 46, and pivoted at 41, 47 about pivots at right-angles to the pivots 33. The frames 39,40 are connected to one another by bars 48 having horizontal portions 54 which limit the outward movement of the wheel supports by engaging the outsides of the parts 31, the bars also being offset at 53 to engage the tops of the parts 31 and limit the downward movement of the frames 39, 40. The insides of the parts 31 are engaged by the lower ends 51, 52 of the frames 39, 40 to prevent inward movement of the wheel supports. The upper ends of the frame 40 are offset and pivoted to the support 36 at the inside of the pivots 33 to enable the wheel supports to fold over the pivots 47, as shown in Fig. 14. Beyond the rear pivots 33, the bars 32 of the wheel supports have extensions 37, Fig. 14, provided with retaining-lugs 38, with which the shoulders 64 of S-shaped links 55 engage. These links are pivoted to the frame 40 at 56, and are connected by links 59, 62 to the handle-bars 18. Stops 57 are provided on the frames 40 for the links 55, and stops 63 for the links 59 on the links 62. To erect the vehicle, the case is opened as shown in Fig. 5, and the whole apparatus lifted by the handle 17 so that the weight of the sections 1, 2 effects the erection of the parts, after which the two sections are locked by the link 6 and the turnbutton 8. The seat frame is extended by the pull of the links 22, and, as the links 55 are pulled out by the links 62, 59, they first erect the wheel frames by pressing on the extensions 37 and then raise the locking-frames 39, 40. In folding, when the sections 1, 2 are in the position shown in Fig. 5, the locking - frames 39, 40 fall into section 2 by gravity as also do the wheel frames when touched with the foot, and the section 1 with the seat frame is then folded down over section 2.
