FOLDING BABY-CARRIAGE.

Specification of Letters Patent. Patented" Mar. 30, 1920- Application filed November 15, 1919. Serial No. 338,155.

To all whom it may concern: Be 1t known that I, JULIUS A. Mann, a citizen of the Unlted States, residlng atMinneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Folding Baby- Uarriages; and I do hereby declare the following to be a full, clear, and exact description of-the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in baby carriages, and more specifically to folding running gears therefor, es pecially adapted to support a collapsible basket or hammock preferably of the type disclosed and claimed in my co-pending application filed May 21,;1919, under 5. N

298,718, and entitled Baby-carrying basket.

To the above end, generally stated, the

invention .consists of the novel devices and combination of devices hereinafter described and defined 1n the claims.

In the accompanying drawings which illustrate the inventlon, like characters 1nd1-.

Fig. 4 is a VlBW partly in side elevation:

and partly in longitudinal section taken on theline 3.3 of Fig. 3;

Fig. 5 is a detail View in section taken substantially on the line 55 of Fig. 3, on an enlarged scale; and 1 Fig. 6 is a side elevation, showing the running gear folded.

The folding running gear includes a reach 7, front and rear posts 8 and 9, respect1vely,

a pair of reach brackets 10, two pairs of dius reds 1., fron and ree pair fs u axles 12, wheels 13 joi rnaled on said axles 2, en a pair of sp e ding t g l s 1 The reach 7,'and posts-8 and ,9, as shown, are preferably of ub la f rm, a d the en f aid each and t lo er nd of a posts, r pi o allyeonn e e to the rea brackets 10 by horizontal pins 15 and 16,

respectively. By reference to Fig. 4, it will be noted that the pivot pins 16 are located below and rearward of the ends of the reach 7, to permit the posts 8 and 9 to clear said ends when in operative or upright positions, and to be folded into inoperative positions under the reach and into substantially parallel arrangement therewith.

The reach brackets 10 are provided with horizontal inwardly projecting arms 17, and upwardly and outwardly inclined arms 18 in the form of inverted channels. The arms 17 straddle the reach 7 and thereby act as stops to limit the upward pivotal movements of the brackets 10 on the reach 7, and the arms 18 are arranged to straddle the posts 8 and 9 and act as stops to limit the inward swinging movement of said posts vand normally hold the same in diverging relation in respect to eachother. By causing the

arms

17 and 18 to straddle the reach 7, and posts 8 and 9, said reach and posts are securely held against lateral twisting movement on their pivot pins.

To each arm 17 is intermediately secured a clip 19 arranged to embrace the reach 7 and yieldingly hold the brackets 10 against pivotal movement thereon. Also secured to each arm 18 is a similar clip 20 arranged to embrace the posts 8 and 9 and yieldingly hold them against pivotal movement on the brackets 10. p

Formed with each pair of reach brackets 10 is a pair of downwardly and inwardly diverging arms 2.1 to which radius rods 11 are pivoted in pairs and quite close to the bracket 10. The pivots for the radius rods 11 are formed by bending their inner ends laterally downward to form short vertical trunnions and inserting the same through seats in said arms and securing the same against removal therefrom, by cotter pins22. The pivotal connectlons for the radius rods 11 are such as to permit swinging move-. ment of each pair thereof toward and from each other, and also to permit said rods to be folded into substantially parallel ar rangement with the reach 7 Hook-like fingers 2 3,911 the outer ends of the arms 21,

afford stops to limit the outward swinging movement of the radius rods 11. The outer ends of the radius rods 11 are connected to the inner ends of the stub axles by vertical pivots 24, and the outer endsof the spreading toggles 1a are connected by pivots 2.5 to the radius rods 11, inward of the pivots 24. Extensions 26 are formed on the outer ends of the spreading toggles 14 and are provided with depending cam pins 27 which work in slots 28 formed in laterally and in- 7 wardly projecting arms 29 on the inner ends of the stud axles 12. By reference to Fig. 2 it will be noted that the pivotal connection between the members of the spreading toggle 14 is slightly beyond a dead center, and further outward movementthereof is prevented by the engagement of the cam pins 27 with the inner ends of the slots 28. The cam pins 27, by their engagement with the arms 29, securely hold the stub axles 12 against pivotal movement on the radius rods 11.

Gbviously by buckling the spreading toggles 14, the radius rods 11 may be moved inward into substantially parallel arrange- "11181113 with one another and the reach 7.

This movement of the radius rods 11 also carries the Wheels 13 into relatively close arrangement with each other, as shown by broken lines in Fig. 2. To complete the folding of the running gear the posts 8 and 9 are swung outward and downward and then into overlapping position, the one with the other, and under the reach 7, as previously described. This folding movement of the posts 8 and 9 will also cause the reach brackets to swing on the pivots 15. When the running gear is thus folded, the same will appear as shown in Fig. 6.

Formed in the upper end of each post 8 and 9 is a hook 30, and secured to said posts slightly below the hooks 30. Also secured to each post 8 and 9 is a pair of upwardly diverging prongs 31 to the upper ends of which is secured. a relatively short horizon tal handle 32.

To lock the running gear against rolling movement, when left standing, there is secured to the rear rivets a pair of lock fingers 33 arranged to be turned between certain of the spokes of the rear wheels 13 to lock the same against turning movement. These fingers 33 may be swung, inward under the'rear spreading toggle 14, as indicated by broken lines in Fig. 2, when not in use. When the lock fingers 33 are set to lock the rear wheels 13, the same engage the ends of the stub axle arms 29 as stops, as shown in Fig. 2.

' Removably suspended from the upper 5 ends of the posts 8 and 9 is a collapsible baby carrying basket or hammock 34, previously referred to, and preferably made from canvas, or other suitable fabric, and has in its top and bottom marginal edges metal reinforcing rods, not shown. A folding hood 35, is attached to the basket 34 and the basket 34 therefrom with freedom for lateral swinging movement. Secured to the intermediate portion of the basket 34, at the sides thereof, are two buckle-equipped retaining straps 38. Two upwardly diverging buckle-equipped straps 39 are secured to the reach 7 and opposite sides of the basket 34 to limit the swinging movement thereof, or hold the same against swinging movement.

By unbuckling the straps 39, the basket 34 may be removed from the running gear by releasing the rings 37 from the hooks 30. The running gear may then be folded, as previously described, and secured in folded position by the sections of the straps 39 remaining attached to the reach 7.

The above described invention, while extremely simple, and of comparatively small cost to manufacture, has in actual usage, proven highly efficient for the purpose had in view. When the running gear is folded the parts thereof are very compact and occupy comparatively little space so that the same may be readily taken into a street car, or other conveyance, while the basket with the baby in it may be carried in the arms.
