FOLDING BABY-CARRIAG E.

SPECIFICATION forming part of Letters Patent No. 410,963, dated September 10, 1889.

Application filed September 29, 1888. Serial No. 286,720. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN ELLIS, of Jersey City, New Jersey, have invented a new and useful Improvement in Folding Baby-Carriages, of which the following is a specification.

Figure 1 is a side view of the carriage in condition for use. Fig. 2 is a plan View of the same. Fig. 3 is a longitudinal section of the same. Fig. 4 is a transverse section of the same through the lines a: m, Fig. 3. Fig. 5 is an end View from the foot of the carriage in its completely-folded condition. Fig. 6 is a detail view showing a vertical cross-section through one of the wheels. Fig. 7 is a detail of the central portion of the wheel. Fig. 8 is a side view showing the adaptation of the carriage to a cradle, being supplied with rockers and the wheels being folded. Fig. 9 is an end view of the. same as Fig. 8. Figs. 10 and 11 are respectively a plan and side view of the rockers detached. Fig. 12 is a parasol detached, and Fig. 13 is a clip by which the same is secured in place.

An important part of my invention consists in the construction and arrangement of the wheels, which I will first describe.

The spokes of the wheel, as shown in Fig. 8, are secured at their inner ends to a ring 1, which contains an internal track 2, concentric with the rim of the wheel.

3, 4, and 5 are frictionwheels, upon which the track 2 runs and having their centers at the three points of a triangle. These'wheels turn, respectively, upon the pivots 6, 7, and 8, each of which is secured 011 opposite sides of its wheel in the plates 9 and 10. The frictionwheels, of which the number may be varied, and the track serve to center the vehiclewheel with respect to the plates 9 and 10, and it only remains to connect these plates with the object to be carried. This is accomplished by means of the arm 11, which extends at one side of the wheel a sufficient distance to clear the rim of the wheel, as shown in Figs. at and 6, and which may be rigidly secured to the plates 9 and 10 by any suitable connection, such as the studs 12 and 13, a continuation of the stud 13 forming in the example shown in the drawings a pivot 6 of the frictionwheel 3. The arm 11 of each wheel of the carriage extends vertically upward, and is connected with the carriage-body as follows: For

the front wheels the top of the arm is pivoted upon the outer end of a stud or bolt 14, which passes through the side of the body near the top thereof, so that the arm may swing upon this bolt or stud. The forward swing of the arm is limited by the stop 15, from which a lip extends backward outside of the arm 11, so as to hold that arm firmly against the side of the carriage.

16 is a bolt, which is provided with guideways 17 on the bottom of the carriage, and which may be shot out through the side of the carriage, as shown, so as to hold the arm 11 firmly against the stop when desired.

The arrangement for connecting the arms 11 of the two rear wheels to the body are similar, and the parts are similarly numbered in the drawings; but in this case provision should be made for producing a greater distance between the two rear wheels than between the two front wheels, so that in folding two of the wheels will fold inside the other two. This may be accomplished, as shown in the draw ings, by pivoting thearm 11 upon the stud 18, extending laterally from the side of the wagon, instead of pivoting it directly upon the side of the wagon. In the drawings are also shown springs 19, arranged in the arms 11 of the two rear wheels between the shoulders 20 and 21 upon the upper and lower sections of those arms. Now, it will be observed that when in position for use the wheels will be held securely at the lower ends of the arms 11, and will revolve upon the friction-wheels 3, 4, and 5, forming a firm and durable bearing for the wheel. The body willbe supported vertically upon the arm by the pivotal bolt 14, and all lateral motion of the arm will be stayed by the lipped stop 15 in conjunction with the bolt 16. When, however, it is desired to fold the wheels by withdrawing the bolts 16, the front wheel on each side will be free to swing backward and upward, and the rear wheel on each'side will be free to swing forward and upward outside of the front wheel, as shown in the drawings, so that they will occupy the position with respect to the body of the vehicle shown in Figs. 8 and 9. Having folded the wheels in this position, the structure may be used as a cradle by the addition of rockers, or it may be still further folded. For the latter purpose provision is made as follows: The

seat 22 may be pivoted upon the top of parallel links 23 and 2t, so that when in position for use its rear end will abut against the rear end of the carriage-body, as shown in Fig. 3; but when not in use it may be swung forward and downward, as indicated by dotted lines in Fig. 3, where it may rest in a depres sion formed for that purpose in the bottom of the wagon. \Vhen in this position, it will be wholly below the level of the tops of the sills of the body. The foot 25 of the body is hinged to the bottom sill at 26, so that it may be swung backward and downward, as indicated in dotted lines in Fig. lVhen in its raised position, it may be held in place by any suitable connection with the sides of the bodyas, for instance, by the lugs 27 and hooks 38. The other end maybeheld in place by the lugs 30 and bolts 31. The sides of the body are hinged at different points. Thus, as shown in Fig. 4, one side of the body is divided in two parts on the line 32, which is of snfticienthcight to admit of the folding of that side inwardly and downwardly above the two ends which have already been folded, and the one section of the side is hinged to the other section, as at 33. The other side of the body is divided into two parts on the line 34:, which is sufficiently high to admit of the inward and downward folding of the upper section of that side above the other side, the two wheels on the other side and the two ends in their folded position. The two sections of the second side are hinged together, as at The handle 36 may be hinged to the head or rear end of the carriage, as at 37, and when. in its unfolded position may be held in place by the brace 38, hinged at 339 and passing through a slot in the rotatable cross-bar l0 of the handle, being held in position by a pin 41. When it is desired to fold the handle, this pin may be withdrawn, the handle swun downward against the head of the wagon, as shown in Fig. 9, and the brace 38 swung upward, projecting, in order to do so, through the slot in the rotatable cross-piece 40.

If desired, a parasol may be provided for of ordinary construction by having the detachable arm 4.2 project upward from the head of the wagon, and provided at its upper end with a horizontally-projecting clip (shown in Fig. 13) to grasp the handle of the parasol, as shown in Fig. 2, and secure the same in the position required. By detaching this clip from the parasol the same may be readily folded and the arm t2 may be detached from the body of the wagon.

\Vhen the wheels and body have been folded, as above indicated, they will be in position shown in Fig. 5, where 4.3 is the bottom of the body. 25 is the foot thereof, the head 52 being on the same horizontal plane as the latter. it is the lower section of one side thereof. $5 is the upper section of the same side. 40 is the front wheel on the same side. 47 is the rear wheel 011 the same side. 48 is the lower section of the opposite side of first described, the body is allowed to remain unfolded, and the rockers shown in Figs. 7 to 11, inclusive, are applied as follows: \Vhen not attached to the structure, these rockers are practically flat, as shown in Figs. 9 and 11, consisting of a flexible portion, preferably of metal, 53, to which are hinged at its ends the links 5t and 55, having hinged to them at their free ends the braces 56 and 57 and the pieces 58 and 59. Projecting laterally from the sides of the links 5+1; and are the shoes (30 and 61. Tenons are provided on the free ends of the braces 56 and 57, as shown, adapted to fitinto mortiscs in the piece at the points 62 and Now,when it is desired to attach this rocker to the structure of the carriage,verticallongitudinalslots (ii and (35 (shown in dotted lines in Figs. 8 and 9) are provided,into which are titted the pieces 58 and 59. At the same time the tow ons of the braces 50 and 57 are titted into the mortises of the piece 53, thus springing that piece into the bowed form shown in Fig. 9, in which form it serves as a rocker of the cradle. A similar rocker is provided at the other end. The shoes (30 and 61,which are provided upon opposite sides of the two rockers, are so placed that they will serve as rests for the rims of the wheels when in their folded position to prevent the same from swinging downward, as is clearly shown in Fig. 8. By applying this form of rockers to the structure the carriage may be readily converted into a cradle, and at the same time, by reason of their flat form, the rockers, when detached, will occupy so little room that they may very readily be transported or stored.

It will be observed that the arms 11, by which the wheels are connected to the wagoir body, are so arranged that they do not 0ccupy the space below the wagon-body, but are at the sides of that space. It will also be observed that they are attached to the sides of the wagon-body instead of to the bottom and that their point of attachment is above the level of the wheel in each case. It will also be observed that in the construction shown the track 2 is connected wit-h the wheel, and the friction-wheels 3, -l-, and 5 are mounted upon the arm 11, this arrangement having certain advantages over the reverse; but I do not desire to limit myself to this arrangement.

The utility of the structure which I have above described will be especi all y appreciated in traveling, and by persons living in apartments, where the facilities forkeepin g a babycarriage are limited.

IIO

I wish it to be understood that I have in the foregoing description described the form of construction in which I at present prefer to embody my invention, but I am aware that this form of construction may be varied to an indefinite extent without departing from the principle of my invention, and I therefore do not wish to be.understood as limiting myself to the form of construction described.

I do not in this application make any claim for the wheels as a separate part from the vehicle, since such claims are to be made the subject of a separate application.

I claim 1. In combination, substantially as described, with the body of a vehicle and 'a wheel thereof, an arm pivoted at its upper end at or near the top of the vehicle-body, upon the lower end of which arm the wheel is journaled, and mechanism connected with said body at or near its bottom, whereby the swinging motion of said arm is stayed.
