FOLDING BABY-CARRIAGE.

Specification of Letters Patent.

Patented Nov. 19, 1907.

Application filed July 8,1907- Serial No. 332,613.

thereon, to be a full, clear, and exact de-' scription of the same, and which said drawings constitute part of this specification, and

represent in Figure 1 a side view of a folding baby carriage constructed in accordance with our invention, shown in the open position. Fig. 2 a sectional view of the carriage in the open position with'the back reclined. Fig. 3 a side view of the same in the folded position.

.Fig. 4 a plan view with the seat and portions of the carriage above the side bars removed. Fig. 5 a sectional view on the line a-b of Flg. 4. Fig. 6 a broken side view illustrating the arm braces as pivoted directly to the side bars.

This invention relates to an improvement in folding baby carriages, the object being a simple arrangement of parts whereby the carriage can be conveniently opened and as readily folded, and which when opened, may be firmly looked in that position; and the invention consists in certain details of construction and arrangement of parts as will be hereinafter described and particularly recited in the claims.

For lightness and strength,

side bars

2 and 3 are formed from angle iron the forward ends connected by a dash rail 4, the

rear ends

5 and 6 being slightly curved upward and pivoted to the handle bars 7 which are preferably formed integral with the handle 8. The

side bars

2 and 3 are slit at the ends and these

ends

9 and 10 are turned downward, and to them arepivoted the axle frames.

Preferably the central portion 1 of the axle frames have their

ends

12 and 13 turned outward to form axles for the wheels 14, the ends of the frame 11 being supported by braces 15 and 16 which are pivoted to the

ends

9 and 10 and to the central portion of the axle frame, but it is apparent that the

axles

12 and 13 might be formed integral with the braces 15 and 16, and the central supporting braces 20 are pivoted.

'gagement with the locking bar. the arms 22 near their rear ends are locking portion 11 riveted to these braces, in either case forming a rigid axle frame. The central portion of the axle frame bows inward and upward and over a transverse brace 17 which is secured to the underside of the

side bars

2 and 3 near the center thereof. Pivoted to the handle bars 7 near their lower ends is a U-shaped yoke 18 which passes under the transverse brace 17 and over the axle frames 11 and so as to hold the axle frames in their open position.

Riveted to the side bars rearward of the center are springs 19 which extend forward and upward, and to the forward ends arm- 'lho arms curve rearward and are connected by pivots 21 with the forwardends of arms '22 which extend rearward into engagement with the handle bars 7. The rear ends of the

side bars

2 and 3 are connected by a stay I'm 22; on which is mounted a latch bar 21, the ends 25 of which are turned inward and notched to engage with a locking-bar 2c, the ends of the bar passing beneath studs 27 mounted in the

side bars

2 and 3 and forward into engagement with the arm braces 20, springs 28 being mounted on the stay rod 23and acting to normally hold the latch in engagement with the locking bar 26. If desired, a stop 29 m ay be mounted on the latch bar 24 by which the ends may be conveniently lifted out. of en- Riveted to plates 30 formed with looking notches 31 and stop fingers 32 and formed with a slot 33.

Secured to the locking plates 30 is a back frame 34, the pivots 35 passing through the slots 33 in which it is free to move so that the back frame has an up and'down movement with res ect to the plate. This back frame is provi ed with studs 36 which will enter the locking notch 31 to hold the back frame in a vertical position, as shown in Fig. l ofthe drawings, or strike the stop linger 32 to limit the rearward movement of l he back frame, as shown in Fig. 2 of the drawings. A seat 3-37 rests upon a seat bar 38 the ends of which are connected with the hinged ends of the arms 22 and braces 20 by links 23$). The back -10 is formed from flexible material suspended f th b k Emi o 34 an cmineelvd lo lhv rear of the seat 37 and at ll from ol' the seat the front of the seat and from die .dnsh rail 4., which well may be covered by an apron 42 when the carriage is arranged for a reclining position. tiveted to the arms 22 are top supporting plates 43 which have locking notches a4, stop fingers and slots 46 and extending through the slots are rivets $7 on which are mounted the three

bows

48, 49, and 50 of the top 51, the

bows

48 and 50 being connected by

hinged links

52 and, 53 which when thrown into line will hold the top in an extended positio'n. The top is held in an upright position by providing the central bows 49 with studs 54 which may engage with the notches 44; in the plate 43. W'hen turned the bows 48 will strike the plates 31, or if tipped forward the lug 54 will engage with the fingers 45. The parts thus far described have been referred to as in their open position, and to fold the carriage the

links

52 and 53 will be broken down to allow the top to be folded. The latch bar 24 is then turned to lift theends 25 out of en agment with the locking bar 26. The ban le is then thrown forward, which also throws the seat forward and with it the top, the handle bars extending parallel with the side bars, This forward movement of the handle bars throws the, yoke 18 forward releasing the axle frames and so that when the yoke is in its closed position the axle frames and wheels may be folded. inward and interlocked by means of a turn-button 55 pivoted. to the transverse brace 17 and adapted to be turned at right angles thereto 'so as to extend over the rims of the wheels. The wheels in their closed position resting upon the yoke 18 prevent the movement of that yoke and hence prevent I the movement of the handle-bars so that by locking the wheels all the parts are locked in their folded or closed position. T 0 open the carriage it is only necessary to turn the but ton 55 and grasp the handle bar, holding it up so that the weight of the carriage brings. the parts into open position, the movement of the yoke throwing the axle frames outward so as to make the opening practically automatic. By thus arranging the seat and supporting it, it folds'forward or moves forward when folded so that the parts fold very closely together. By forming the side rail .from angle irons an exceedingly light frame is provided, and yet one sufficiently strong; at the same time makes it convenient to curve the ends upward for connection with the inner ends of the handle bars and. provides for the turning down of the

ends

9 and 10 for connection with the axle frame.

While we refer to provide the springs 19 to give a yie ding support for. the seat, they may be omitted and the ends of the braces so extended and pivoted to theside bars as shown in Fig. 6', the parts being capable of folding in the same way as beforedescribed.
