BABY- CARRIAGE.

Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed November 19, 1904. Serial No. 233,489.

To all whom it may concern:

Be it known that I, ARTHUR J. Anaisis, a citizen of the United States, residing at Chicago, in the count of Cook and State of Illinois, have invented a new and useful Improvement in Baby-Carriages, of which the following is a pecification.

My invent-ion relates particularly to go carts, or folding baby-carriages, peculiarly adapted for use in traveling.

My primary object is to provide a thoroughly practicable and durable carriage of the character indicated, provision being made for automaticfolding and unfolding so far as consistent with thoroughly commercial practicability.

The present invention constitutes an. 1mprovement on the invention set forth. and generally claimed in my application No. 196,766, filed March 5, 1904.

The invention is illustrated in the accompanying drawings, in which Figure 1 represents a side elevatlonal view of my improved folding carriage in its preferred form the handle. being broken; Fig. 2, a plan view .of the same; Fig. 3, a transverse section taken as indicated at line 3 of Fig. 1; Fig. 4, a broken sideelevational view showing the position of certain parts preparatory to locking the brace links serv ng to support the seat-support; Fig. 5, a side view of the carriage in a folded condition; and Fig. 6, a plan view of the carriage in the folded condition, with the seat and other leather parts removed.

In the preferred construction, A repre sents a substantially horizontal runninggear frame; B, sleeves pivoted on the side members thereof and equipped with wheel supports, or forks, B in which the wheels are journaled; C, an inclined seat support having its front end connected by a pivot c with the front portion of the running-gear frame; D, a handle having its lower end con nected by hinges d with the rear end of the running-gear frame; and E, mechanism connected with the seat support and handle and serving, in the operations of folding and unfolding the handle with relation to the running-gear frame, to lower and raise the seatsupport, said mechanism being equipped with mean for locking the seat support and The frame A may comprise U-shaped tubing constituting the front and side members of the frame; the eat support may comprise U-shaped tubing constituting side members and a back member; and the handle may comprise U-shaped tubing with the free lower extremities joined to the free rear extremities of the side members of the running-gear frame. The side members of the running-gear frame are equipped with collars at having shoulders a serving to engage corresponding shoulders with which the sleeve B are provided at their front ends, whereby the forks B are limited in their outward swing when the vertical position is reached. As will be understood, the front and rear forks at either side of the vehicle are connected to be swung to the folded or extended position together. The

member C has the seat 0 connected therewith in any uitable manner. As shown, the seat is supported by leather side pieces 0 and aleather back 0 and there is connected with the front edge of the seat and with the front portion of the running-gear frame a foot support 0, which preferably is composed principally of leather bearing an inserted foot-board 0 The mechanism E comprises, in the preferred construction, a pair of substantially vertical brace-links 6 having their upper ends pivotally connected with the rear portions of the side members of the seat support C and their lower ends equipped with looking members 6 and a pair of two-part flexiblelinks 6 having pivotal connection at the rear ends of their rear members with the lower portions of the side members of the U-shaped handle and having pivotal connection at the front ends of their front members with the lower ends of the brace-links 6. Each flexible link 6 comprise a rear member 6 and a front member 6 (Fig. 4), said members being joined by a pivot 6 The front end of each member 6 bears a forwardly extending projection c, which constitutes at once a thumb-piece serving in the operation of extending the flexible link, a guard preventing the thumb from being pinched when the joint is straightened, and

45 J further outward movement, the handle may a stop limiting the downward movement of the joint, thereby constituting a lock for the joint when the pivot 6 drops slightly below the line of the members 0 e. As will be best understood from Figs. 2 and 4 the rear forks B are equipped at their points of junction with the sleeves B with lugs Z) having rear vertical surfaces 5 constituting locking shoulders; and in the rear of these locking shoulders the rear forks B are equipped with horizontal locking shoulder Z2 The locking members 6 have vertical and horizontal locking shoulders corresponding with the shoulders just described. It will now be understood that when downward pressure is exerted upon the thumb pieces a of the flexible links 6 a downward thrust upon the shoulders b and a forward thrust upon the shoulders b will result, the effect being to lock both the brace-links e and the wheel-supports, when the flexible links are fully extended, as shown in Fig. 1. The locking-members c and through them the links, or braces, e, are preferably joined by a cross-rod 0 as shown in Fig. 3.

The manner in which the carriage is folded and unfolded will be understood without further detailed description. The flexible links 6 may be struck upwardly at the joints where the pivots e are located, after which the rear end of the seat support may be lifted slightly to permit the locking mem bers e to pass the members I), after which the handle may be folded forwardly upon the running-gear frame to bring it into approximately the plane of the running-gear frame, as shown in Fig. 6. Either before or after the handle is folded, the wheel supports may be swung inwardly to bring the wheels up beneath the running-gear frame and close to the plane of the latter. WVhen it is desired to unfold the carriage, the wheel-supports may be swung downwardly and outwardly till the shoulders a limit then be swung rearwardly to the position which it occupies in use, and the flexible links 6 may then be flexed to allow the looking members 6 to enter their seats, after which the flexible links may be straightened to lock the brace-links c and the wheel-supports. It will be understood, of course, that while the handle is being swung forwardly or rearwardly, the members 6 ride upon the side members of the running-gear frame, thus swinging the lower ends of the brace links forwardly or rearwardly, as the case may be, to lower or raise the seat-support. Thus it appears that the raising and lowering of the seat support is effected automatically by the operations of extending and folding the handle with relation to the running-gear frame. Moreover, it appears that in theoperation of straightening the flexible links 6 the brace-links and the wheel-supports are simultaneously locked; and vice versa, the brace-links and the wheel sup ports are simultaneously unlocked in the op eration of flexing the two-part links 6 It will be readily understood that many changes in details of construction within the spirit of my invention are feasible, hence front portion of said frame, a forwardly swinging handle having its lower end pivoted to the rear portion of said frame, a forwardly swinging brace-link pivoted at its upper end to the rear portion of said seatsupport, the lower portion of said bracelink finding a support on said frame during the swinging movement, and a flexible twopart link having pivotal connection at its rear end with said handle and pivotal connection at its front end with said brace-link for the purpose set forth. i

2. The combination of a running-gear frame, a pivoted seat-support, a pivoted handle, pivoted wheel-supports, a pair of brace-links pivoted at their upper ends to said seat-support and provided at their lower ends with wheel-support locks, and a pair of two-part links having pivotal connections with said handle and thelower ends of said brace-links, each two-part link having a stop for preventing'downward flexing, substantially as and for the purpose set forth. 3. The combination of a running -gear frame, a pivoted seat-support, a pivoted handle, pivoted wheel-supports, a pair of i brace-links pivoted attheir upper ends to saidseat-support and provided at their lower ends with wheel-support looks, and a pair of two-part links having pivot connections with said handle and the lower ends of said brace-links, one member of each twopart link having a project-ion adjacent to the connection between the members serving as a thumb-piece, guard and stop, substantially as and for the purpose set forth.

4. The combination of a substantially horizontal running-gear frame, an inclined seat-support having its front end pivoted on the front portion of said frame, wheel-supports equipped with two pairs of lockingshoulders, a pair of upright brace-links hav ing their upper ends pivoted to the rear portion of said seat-support and equipped at their lower ends with locking-shoulders engaging said mentioned locking shoulders,

a handle having its lower end pivoted on the rear portion of said frame, and a pair of fiexible two-part links having their rear ends pivoted to the lower portion of said handle and their front ends pivoted to the lower ends of said brace-links, substantially as and for the purpose set forth.

5. The combination of a substantially horizontal running-gear frame, an inclined seat-support having its front end pivoted on the front portion of said frame, a handle having its lower end pivoted 0n the rear portion of said frame, wheel-supports pivoted on said frame and equipped with lugs having vertical shoulders, a pair of bracelinks having their upper ends pivoted on the rear portion of said seat-sup ort and their lower ends equipped With s oulders engaging said first-named shoulders, and a pair of flexible links connecting the handle with the lower ends of said brace-links,

whereby actuation of the brace-links and locking of the brace-links and wheel-supports may be efi'ected, substantially as and for the purpose set forth.

6. In a perambulator the combination of a running gear frame, a seat frame hinged thereon, a handle hinged to said running gear frame, braces for supporting the seat frame pivoted thereto, wheel supports r0- tatably mounted on the running gear frame, means carried by the said braces for locking the wheel supports, a cross bar connecting said braces together, and a toggle connecting said cross bar with said handle.
