To all whom it may concern:

Be it known that I, ALBERT E. MOGILL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Folding Baby-Carriages, of which the following is a specification.

This invention relates to folding baby car- 'iages, more particularly to doll carriages of that type in. which the wheels fold under the running gear frame transversely thereof in a substantially fiat and compact form while the handle folds downwardly upon the frame, and the invention has for its primary object to provide improved simple and effective means whereby the folding and unfolding action of the handle will automatically and respectively fold and unfold the wheels in one operation.

A further object is to provide improved means whereby the folding and unfolding action of the handle will cause the wheels respectively to fold and unfold in pairs sequentially.

To the attainment of these ends and the acconn lishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating an embodiment of the invention, and in which- Figure 1 is a side elevation of a baby carriage constructed in accordance with the principles of this invention. Fig. 2 is a view similar to Fig. 1, showing the same partially folded or collapsed. Fig. 3 is a sectional view on line 33 of Fig. 1, showing in dotted lines the wheels on one side in a partially folded position. Fig. 4 is a detail sectional view on line 4l--t of Fig. 1.

In the drawings, the seat and its supports have been omitted, as the construction of these features forms no part of the present invention.

Referring more particularly to the drawings, the running gear frame is shown as being composed of spaced side bars or members 10, which are connected at their forward extremity by a cross bar 11. The rear ends of the side bars 10 are connected together by means of a cross bar 12, which bar also serves as a means of pivotally connecting the side bars of the handle 14: and the running gear frame.

The wheels are mounted in two pairs 15, 16, one pair on each side of the running gear frame, and each wheel is suitably ournaled in a bracket or wheel support 17 of any desired construction and which are rotatably connected to the side bars 10 in any suitable manner. The wheel brackets or supports 17 are connected together in pairs by any suitable means, preferably by means of longitudinal bars 18, 19 respectively, which are secured to the inner branches or faces of 'the wheel sup-ports, so that when the wheel on one side is folded or unfolded, the other wheel on the same side will make a like movement. The wheel supports are held against longitudinal displacementwith respect to the side bars 10 in any suitable manner, preferably by means of clips 20 secured to the side bars 10 and through which a portion of the wheel supports pass.

On each side of the running gear frame is mounted a deflectable upright or standard 21 which may be pivotally mounted in any suitable manner but are preferably pivoted directly to the respective side bars 10, the bolts or fastening devices 22 forming the pivots for the uprights. These uprights 21 are provided with downwardly extending portions 23 which project between the connecting bars 18 and the free extremities of the portions 28 are connected. by a cross bar or member 24: to form a bail-like portion. These uprights or standards 21 with the bail-like extensions 23 are preferably lo cated adjacent the forward wheel supports 17, so that when the wheel supports are in an unfolded position, the extension 23 will stand between the connecting bars 18, 19, to brace the forward wheel supports and to hold the latter against collapsing. The uprights or standards 21 are adapted to be moved about their pivots by the folding and unfolding movement of the handle 14: and in order to'accomplish this operation, the upper extremities of the standards 21 are connected respectively to the side bars of the handle 14 by means of connecting links or members 25.

The wheel supports may be locked in their unfolded position by means of deflectable members 26, one of which is pivotally connected as at 27 to each of the side bars of the running gear frame, preferably adjacent the rear wheel supports 17. A portion of each of these deflectable members 26 depends below the running gear frame and the lower free extremities are connected in the usual manner to form a bail-like member. The upper portions 2'7 of the members 26 pro ject above the running gear frame and are connected respectively to the side bars of the handle 1st by means of links 28 which latter are pivotally connected to the handle and to the portions 27 so that when the handle is folded or unfolded, the locking bail will be moved about its pivots.

The extremity of the connecting bars 18 and 19 preferably project beyond the rear wheel supports 17, as at 29, and secured thereto is a member which is spaced from the extremity 29 to form a catch into which the respective members 26 enter when the wheel supports and handle are in unfolded positions to lock the structure in position for use.

In order to lock the handle against folding movement, there may be provided locking braces 30, 31, which are pivotally connected as at the free extremity of the locking members being secured respectively to the side bars 10 of the running gear frame and the side bars of the handle lat. lVhen the locking braces are thrown into line with each other, the handle will be secured against movement. When it is desired to fold the handle, the locking braces 30 and 31 may be deflected with respect to each other to permit the handle to fold downwardly upon the running gear frame, .as shown more clearly in Fig. 2.

In order to cause the wheels and wheel supports to simultaneously fold and unfold in pairs in one operation respectively with the folding and unfolding movement of the handle, there is provided a link 33, which is supported by and surrounds the connecting bar 19 and also surrounds the adjacent depending extension 23 of the upright or standard 21, above the cross bar or connect ing member 2-11., as shown more clearly in Fig. This link or ring 33 is of a size to loosely engage the parts and to permit free adjustment thereof.

A second connecting bar 34 is provided which connects the wheel supports 17 on the side of the running gear frame opposite to the side on which the connecting bar 19 is located, and this connecting bar 3 1 is preferably located in close proximity to the respective side bar 10 and is spaced from the connecting bar 18. A link or ring 35, similar to the link or ring 33, surrounds the connecting bar 3st and also the adjacent depending portion of the upright or standard 21. This ring or link is also of a size to loosely engage the parts to permit the latter to more freely when the handle 14 is unlocked and adjusted.

lVith this improved construction it will be apparent that when the handle 14 is folded or unfolded, the links 33 and 35 will be moved by the depending portions 23 of the uprights or standards 21 along the respec tive bars 19, 3-1:, until the links assume such a position on the bars that a further deflection of the uprights or standards 21 about their pivots, will draw the bars 19, 3 1 inwardly toward each other to move the wheel supports 17 about their pivots and to cause the wheels to fold against the bottom of the running gear frame. Before the links 33, 35 have reached positions to draw the bars 19, 3% toward each other, the locking bail 26 will have been deflected about its pivot to disengage the catch formed by the extremity 29 of the bars 18, 19 and the members 30. The unfolding movement of the handle 1-1 will cause the wheel supports to be deflected outwardly away from each other and into a position for use and when the wheel supports have reached this position, the locking bail 26 will enter the catches to lock the wheels in position. It will be apparent that the movement of these uprights or standards 21 and the depending portions 23 in response to the folding action of the handle will swing the wheel supports inwardly and carry the wheels toward the plane of the running gear frame and in order that this foldinp action of the two pairs of wheels may take place sequentially so that the wheels of one pair will not clash with those of another pair and thereby defeat the folding movement, the connecting or cross bar 2st between the depending poitions 23 of the uprights or standards 21 is provided with a cam or bend 36, with which the link or ring 33 engages as the member 21 moves toward the plane of the running gear frame to hasten the folding act-ion of the pair of wheels to which the ring is connected. This cam or bend 36 is of such a size and is preferably so located that the pair of wheels to which the ring 33 is connected will begin to fold before the other pair of wheels, so that in their folded positions the pairof wheels 16 will fold between the other pair of wheels 15 and the bottom of the running gear frame.

hen the handle is moved from its unfolded position, the outermost pair of wheels will swin about their pivots more rapidly than the other pair of wheels to permit the pairs of wheels to unfold sequentially.

During the folding movement of the handle, the rings or links 33, 35 will travel to gether along the bars 19, 34:, until the ring 33 engages the cam 36. A further movement of the handle in the same direction will force the ring 33 over the cam 36 to fold the wheel 16. During a portion of this folding movement the ring 35 will travel still farther along the bar 34 before it has assumed a position to draw the corresponding supports inward upon the other supports, as shown in Fig. 2.

In order that the invention may be fully understood, the details of the foregoing embodimentthereof have been thus specifically described, but
