Divided and this application filed June 18, 1908. Serial No. 439,175.

To all. i/wm4 "it may concern:

. Be it known that I, ANTHONY W. Loen- BoUeH, a citizen of the United States, residing at Detroit, Michigan, have invented certam new and useful Improvements 1n Collapsible'Baby-Carrages,.ot which the .fol-

lowing is a specification.

Thls inventlonrelates to improvements in baby cai lagps.

It relates particularly to improvements in folding baby carriages, and `is especially designed and adapted `for use on the Jfolding bab rcarria e shown in Letters Patent No.'

- 866,145, Vissued September 17, 1907, to Otto followingspecication.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of 'this \specification, inl which: A

Figure 1 is a side elevation of a structure embodying the features oi' my invention, portions of the handle being broken away and the wheels removed. Fig. 2 isa rear `elevation of the structure appearing in Fig. l, a portion of tliebandle being brolren away. F ig.' 3 is an enlarged detail vertical section taken on a line corresponding to line 3--3 oi l Fig. 2, showing details of the seat support.

Fig. 4; is a detail vertical section, showing details of the front seat supporting bracket. In the drawing, the sectional vie'ws are taken looking inthe directionv of the little arrows at the ends of the section lines, and similar'numerals of reference refer to simi- .lar parts throughout the several views.

'Referring to the drawing, 1 re resents the running gear frame. rlhe han le. 2 is pivotally secured at the 'rear ofthe running gear frame by means of the pivots' 3. Un

' each-,fof the side bars of the running gear trame are clip-like hangers l for the wheel supports 5. rlhe wheel supports are preferably formed, of rods having downwardlyprojecting wheel-carrying arms 6 with suitable journals, es 5, ior the wheels. The wheel supports are pivotally supported on the hangers, so that they are free to swingv therein to permit the wheels to be folded upon eachother under the running gear frame. l

The wheel supports 5 are provided with oli'sets farming cranlelike arms 8, the otl'sets being jfn'eiferal'ily inclined downwardly toward therear, as clearly appears from the drawing.

A pair of levers Q'is mounted on the side bars of the ruiming gear frame by means of the pivots 10, the pivots being located above the oll'sets or arms 8 of the wheel snjjiports. lhc lower ends oi the levers project downwardly below and preferably on the outside of tbc-arms 8 oit the wheel supports, as clearly appears troni the drawing. .)n the lower ends oli' thelevers are .loops .1l arranged to engage the arms 8, so that, when the levers are actuated, they serve to positively swing'the wheel supports in and out to collapse or erect them. 'llie levers 9 j )rei'erably connected to the handle 2 to be actuated thereby, by links 12., the links being adaptedto serve as side bars for the scat 13. lhesc parts described are substantially ,the same the corresponding parts of the patenthereinbetore referred to.

The wheel supports are locked and braced by .means of the braces l14, pivotcd on the running gear tran'ie at These braces are preferably bail-like in iorm, their lowcrends being connected by a suitable cross piece, as 16, which makes them .more rigid and, i'orms a very rigid bracelor the wheel supports.

The arms oi the wheel supports are pro vided with fork-like clips lll', adapted to receive these braces when the wheel supports are in their erected or extendend "position, 'lhc upper ends of the braces 1st are prefer ably curved rearwardly and downwardly be-A yond the pivots l5 thereof, and are connected by the links 1S to the wheel support actuating levers 9. rlhese links are so arranged that, when the braces 14 are in position to engage the wheel supports, i.the pivot connections 19 for the links to the braces are thrown below the ,pivots 15 for the braces to Cji the running` gear frame, so that they serve as an eil'ective lock for the levers, thus securely locking the carriage in its open or erected positioln'as well as bracing the wheel supports.

lhe cross piece 16 of the braces is, as will be observed, at the rear of the carriage, so that it may be engaged by the foot of the operator to release the braces or push them into engaging position, thus forming a very effective and conveniently operated device. l his wheel support and locking mechanism described is made the subject matter of my application filed concurrently herewith, said concurrent application and this application being divisional applications of my application, Serial No. 00582, iiled N ov. 5, 1907.

The seat is preferably supported at its forward. end on the bracket 20, the same being preferably mounted on the pivot 1() for the levers 9. -ilzrtending across the running 'gear frame, toward the rear thereof, is a cross piece 2l. This cross piece is preferably formed of sheet metal and serves as a brace for the running gear frame. The supporting springs 22 for the seat 13 are of the spiral type and are mounted on this cross piece, the cross piece being provided with a socket to receive the lower 'end of the springs,as clearly appears in Fig. 3. `This socket is formed by punching up a part of the body of the cross piece. The upper ends of the springsare connected to the seat by means of the hinge members 2st for securing the back 25 of the seat to the rear end thereof. 'lhe back 25 is secured to the upwardly-projecting portion of the hinge members by mea-ns of the pivot rod 26, the hinge members being provided with a horizontal portion 2T, which extends under the seat, as clearly appears from the drawing. This horizontal portion is provided. with a socket 28 to receive the upper end of the spring 22, the socket being formed by punching' down a portion of the metal,`n it being formed of sheet metal, as is also the cross bar 21. Thus, by a very simple means, l' secure Vthe springs in position and form an effective spring support for the seat. 1

lWhile l have illustrated the various parts in detail in the form preferred by me on account of the structural simplicity and convenience in manipulating the same, l am aware that my improvement is capable of being-considerably varied in structuraldetails without departing from my invention, and l desire to be understood claiming the saine specifically, as illustrated, as well as broadly.

Having thus described my invention, what claim as newand desire to secure by Let ters Patent is:
