COLLAPSIBLE BABY-CARRIAGE.

Application filed Ju1y'19, 1915.

To all whom it may concern:

Be it known that we, OSCAR E. ERIC-KSON and HJALarAR OLsoN, citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Collapsible Baby-Carriages, of which thefollowing is a specification.

This invention relates. to that kind or class of vehicles which are designed to be folded or collapsed for shipping or storage purposes, and to be set up for use as a baby carriage.

The object of this invention is to obtain a device which, when folded or collapsed will have the appearance of a small suit case, provided. with a handle for carrying it, which is easily set up for use asa carriage, and when set up will have a neat and sightly appearance; and which in its set up form is stable, durable, and not liable to become broken, orv get out of order.

\Ve have illustrated a device embodying this invention in the drawings accompany ing and forming a part hereof in which I Figure l is an elevation of the device in a collapsed or folded form. Fig. 2 is a side elevation of the device in its set up form, for use. as a baby carriage. :Fig. 3 -is a rear elevation in the set up form, but with'the handle' and awning of the device noteX- tended.

When the device is collapsed there are exposed to view, at the ends of the receptacle resembling a suit case, the levers D, E, and links F. Lever D forms a riser to lever E, when the device is set up, and said lever E forms an arm rest at said time. The parts A and B are pivotally secured together by the llnks a and pins or pivots b. Riser D is attached to part A by. pin or pivot d, lever E is attached in the same way to part B by pin or pivot e, and levers D and E- are joined together by pivot or pin 6 Link F, which is pivotally attached to lever D by pivot (2 is provided with a pin orprojection G at its free end, and said pin is movable in slot H in lever E. Pin Gr also fits in the'respective cross slots h, h (hereinafter termed notches)-.a- Slots "H and branch or 1 cross slots -h, h are hereinafter referred to as'notched slots. T

- The severallevers D, Rand-links Fwand a, are attached to the parts A, 'B, and to each; other, in such manner as topermit-of the turning of said parts A, :B on links-F, from a position-'whereisaid-parts are in parallel planes,--as'in-'Fig-.: 1, through an arc of approximately two hundred and seventy degrees and into-the position in which they are illustrated. in Fig. 2, so long-as the pins or abutments Gare free to slide in slots H, that is, so long as said pins'are not in one or the; otherxof'thenotchesh, 7L ,When said pins G .are in-said notches h therisers D and arms arerigidly -heldthereby, to gether with seat formed by part -A and back formed-by part "B,-in the'position in which said 'partszarejillustrated in-Fig. -2-, by full lines; and when saidpin Gris in notch h said parts I are maintained in the position which" they --are indicated by broken'lin'esin said,"fipmre. r

Ifare wheel frames and.;J- a'rewheels-rotatably mounted in frames-I. Frames-I are pivotallyattached to part A by hinges K.

7c is the pintle of hinge K, and X are abutments on the part of hinge K which is riveted to said part A. The abutments X are spaced so that when the wheel frame I is turned on hinge K, so as to be at an,

angle of ninety degrees from said part A, said wheel frame is between said abutments. The wheel frames I are respectively made of strap sheet metal which is bent to obtain two parallel sides, between which wheel J turns, (being mounted on an axle at or near one end of said sides); said bending being substantially as follows :--Starting at the end which is lettered L, (see Fig. 3), it extends to hinge K, where it is bent around pintle is, to an angle of one hundred and eighty degrees, and extends back toward the end L to a point which is a greater distance from said end than the radius of the wheel mounted in the frame, when it is again bent to an angle of ninety degrees, to obtain the part which is lettered L it is again bent to an angle of ninety degrees to obtain part which is lettered L (which is substantially parallel with the sides of the frame), and is again bent to obtain the part L and the opposite side of the frame. The part L is adapted to engage, or to be engaged by, the end M of riser D, when the several parts of the device are in the position illustrated in Fig. 2, and thereby the wheel. frames I are held firmly in their set up position, that is, at'right angles to part A.

N is a wheel frame which is pivotally attached to part A by hinges n.

O are wheels in frame N.

P is a two part lever or link. The parts of lever P are lettered 29, p and are pivotally attached together by pin 292. Part 27 of said lever is pivotally attached to part A by pin 9 and part 79 is pivotally attached to frame N by pin 39*.

72 is a pin which limits the pivotal movement of parts 79, p on pin 79 when the device is set up, (as inFigs. 2 and 3).

Q is a foot rest which consists of side bars which are longitudinally movable in part A, the end bar 57, and the apron Referrii'ig to handle C, said handle is mounted between bars R, which are slidably mounted in part B.

1", 1' are bends in bars R, to obtain the diagonally extending parts 1*, which extend over on to part A when the device is collapsed.

S, (see Figs. 2 and 3) arefpins or abutments on the under side of part r ,'of bars R; and when the device is collapsed said abutments S are forced into apertures S of bar 1 When said pins are in said apertures the parts A and B are latched thereby together, so that they cannot turn on links a. Whenbars R are drawn out of the part B said pins S are drawn out of apertures S (see Fig. 2 for said apertures indicated by broken lines in bar (j), and the parts A, B, can be turned on said links. v

T, (Fig. 2) and '1, (Fig. 3) are apertures in bars R, and U, (Fig. 3) are longitudinally movable rods which are mounted in part B, and u is a spring which yieldingly holds said rods in an advanced position. Bars U are bent near the ends to obtain parts U which extend through slots 10 in said. part B, into position to be grasped and brought together'against the resiliency of spring 14, thereby retracting the rods U. )Vhen rods U are advanced the ends thereof are in one or the other of the apertures T, T When the device is collapsed and the handle C forced as near to the parts A, B, as possible, with the pins S in apertures S the aperture T is in position so that said. rods U may enter them, and as said rods enter said apertures T the bars R are latched, so that they cannot be drawn out of said part B until the ends U are forced'togethento retract said rods U from said apertures T. WVhen the device is set up and the handle C and bars R are drawn out the apertures T are in position so that rods U may entersaid apertures, and

thereby latch said bars R in said position.

V, V are U-sha-ped bars, forming the frame of an awning. Bar V is pivotally attached to part B by rods U which extend through apertures in said bars V. The sides of bar V respectively comprise an additional part (V which is-pivotally attached to the ends of bars V by pin V and said bars V are pivotally attached. to the sides of bar V by pins V V 5 is the textile fabric of the awning.

W is a strap which is attached to the riser D, on one side of the device and to the riser on the other side, to provide means for holding an infant in the device when the same is in the condition which is illustratedin Fig. 2.

To set up the device it is held so that the pins G will not leave slot H to enter slots it, if, and parts A, B, are turned on links a. As the device becomes partially set up the part A is turned so that wheel frames I will fall into position extending clownward at right angles to said part A, and'the completion of the set up is accomplished. As said setting up is completed the pins or abutments G will be in position to drop into slots h, and. link F will thenhold the several parts together in said set up posi- We claim 1.
