FOLDING BERAMBULATOR OB GO-CART.

Specification of Letters Patent.

Patented July 30,1907.

Application filed May 12, 1906- Serial No. 316,476.

To all whom it may concern:

Be it known that I, ALBERT E. McGILL, 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 Peran bulators or Go-Carts", of which the following is a full, clear, and exact specification.

My invention relates to folding perambulators or gocarts for small children adapted tobe folded into a compact form, and it has for one of its important objects to provide simple and fiicient means whereby the back of the seat may be extended or inclined as desired to suit the'comfort and ease of the child.

Another object of the invention is to provide improved and simple means whereby the folding of one pair of wheels will also cause the other pair to make a like movement.

A still further object of the invention is to provide certain details in the construction of the device which will especially adapt it for being made with a wooden frame, thereby reducing the cost of manufacture over construct ions heretofore employed.

.\\'i1h a view to the accomplishment of. these ends and certain other objects which will hereinafter appear, the invention consists in the features of novelty which will now be described with reference to the accompanying drawings and then more particularly pointed go-cari constructed according to this invention withthc handle broken away. Fig. 2 is a. plan view thereof. Fig. 3 is a side elevation or edge view of the device folded up. Fig. 4 is an end view thereof. Fig. 5 is an enlarged detail perspective view of one of the rear corners of the running gear frame and connected parts. Fig. (i is an enlarged detail section'taken on the line (i, 6 Fig. 1. Fig. 7 is an enlarged detail section taken longitudinally of one of the side bars of the seat frame. Fig. 8 is a perspective view of one end of the locking bolts or rods hereinafter described. Fig. 9 is a perspective view of one of the bars of the running gear frame, showing the groove in which said rod slides. Fig. 10 is a f raginent. of Fig. 7 showing a different adjustment of the extension. Fig. 11 is a detail cross section on the line 1], 11 Fig. 7, and Fig. 12 is an enlarged transverse section taken on the

line

12, 12 Fig. 1, the wheel being omitted.

The running gear frame is composed of two

side bars

1, 2 which are connected together at their forward ends by'a transverse rod 3. These side bars may be composed of any suitable matcrialbut if composed of wood as is advantageous in point of cheapncss, they will constitute separate parts from the rod 3, which may be in the form of an elongated bolt passing through the ends of the bars 1, f." and also serving as a pivotal support for the lower or forward end of the side; bars 4, 5 of the seat frame. In this example of the invention these side bars 4, 5 are composed of tubing or made hollow as better shown inFigs. 7 and 10, so as to receive the branches 6 of an extension which is composed of said branches and a cross bar at their upper ends, and these parts are of a construction similar to that shown in my application filed Dec. 5, 1904, Serial No. 235,529. This

extension

6, 7 is also composed of tubing and is adapted to slide freely in the bars 4, 5 so as to be withdrawn any desired extent and thereby impart a corresponding extension and inclination to a flexible back portion 8 of the seat 9. This flexible back portion 8 passes over a rod 10 supported under the cross bar 7 by means of thumb nuts 11 screwed on the ends of stems 12 which pass through the crossbar 7 so that when desired the supporting bar 10 may be caused to clamp the'fiexible back extension 8 firmly against the-under side of the bar 7 and thereby hold the back extension 8 at the desired adjustment, preventing it from sagging more than required; In order that the back extension 8 may not slip entirely out of its position between the

bars

7, 10, it is provided at its extremity with a welt 13 of greater diameter than the ordinary distance between the said two bars.

In the use of the back extension the cross bar 7 is pulled upwardly or rcarwardly after the thumb nuts 11 have been loosened until the desired degree of'inclination and extension is attained, and it may then be locked in position by a pin 14 inserted in any one of a series of perforations or sockets 15 in one .of the u branches 6, at a point above the upper end of one of the side bars 4, 5, thus preventing the branches of the extension from slipping back into the side bars 4, 5. The back extension 6-, 7 is prevented from being pulled entirely out of the side bars 4, 5 by a catch 16 adapted to engage in a perforation or socket 17 at the upper end of one of the side bars 4, 5. This catch is in the form of an U shaped spring situated-within the branch 6 and having a lug 17*- embedded in the wall of said branch on one end and a V shaped hook 18 arranged in an aperture 19 in the opposite sidewall of said branch and bearing normally against the inner face of side bar 5 so that when itarrives at the socket 17 it will drop into it but on account of its V shape or beveled-form it will disengage from said socket when the branch 6 is pressed downwardly.

The cross bar 7 ofthe back extension connects the upper ends of the side bars 4, 5 together and constitutes therewith an U shaped seat frame which is adapted to be folded down into close relation to the two

side bars

1, 2 of the running gear frame, and as shown in Fig. 2 it isnarrower than the running gear frame and is adapted to be embraced by folding handle when the latter is turned downwardly into place on top of the running gear frame so that the three members occupy in depth the thickness 01' only two of them. This folding handle is composed of two side bars cbnnected at their lower ends to the rear ends of

side bars

1, 2 by means of ordinary hinges 21, while their upper ends are connected-together by handle bar 22. As is shown in Fig. 2 the handle frame. is

' longer than the seat frame so as to project over and entirely embrace the latter when folded up.

The seat 9 is suspended from the hinged seatirame by seat fabrics 23 and these are attached-to the side bars 4, ,5 by means of rods 24 similar in construction to that shown in my U. s. Letters Patent No. 771,386,

October 4, 1904. The upper ends of these rods are bent around the side bars 4, 5 as shown at 25' and thus connected thereto while their lower ends are attached to the side bars 4, 5, by nuts 26 passing through the upper sides of the side bars 4, 5, but resting against the under sides, see Fig; 7, and being screwed upon threaded extensions 27 of the rods'24, or any other suitable means ofadjustment maybe employed. The

seat fabric 23' may be prevented from sliding down the -rods. 24 in a manner similar to that shown in the above referred to application, that is by nieans of pins or screws 28 and offsets or bends 29 in therods 24, these parts being sorelated that -the fabric 23 ispressed into the bend or offsets 29 by the screw or pin 28, thereby preventing the fabric from sliding. These bends or lass 41, 42 respectively. and the front fork 39 is rigidly screws 28 are the means wherebya clip or collar 30 is held on each of the side bars 4, 5 for attaching the upper ends of seat supporting braces 31 thereto. 'The l'ower ends of these braces 31' are connected to the side bars 20 respectively of the handle by means of links 32 so that when the handle is folded forwardly it will force the lower ends of the braces 31 in the same direction and thereby automatically cause them to'fold up with the folding seat frame 4, 5. When the seat frame is in position for use the lower ends of the braces the hinges 21, if desired, and which is connected to the catches 34 in such a way that when a toe piece 36 on the rod 35 is pressed the catches 34 will releasethe bar 33, permitting the handle to be folded forwardly. The catches 34 may also be connected together for the sake of greater security by across rod 37. When the cross bar 33 isin operative position asshown in Fig.

by guards 38, one on ea'ch-

oftlre side bars

1, 2.

39, 40 are the front andba'ck wheel foiks or brackets, a pair of which is journaled to eachof the side bars, 1,; 2'. oftheiunning gear frame by means of colconnected to the rear fork-4d by means of a rod 43seci'rre'd thereto in any suitable wayso that when the wheel fork at one end' of the running gear frame is folded under the frame as shown in Figs. 3 and 4-, the

fork at the other end will make a similar movement without special attention. In order that these forks 5, it is held against the possibility of rising upwardly may be rigidly locked against rotary movement when in operative position, the upper side of each of the side bars 1, 2 is provided with a longitudinal groove 44, an example of which is shown in Fig. 9, and in each of these grooves is situated a longitudinally movable bolt or locking rod 45, which, if desired,.may be round, and which .passes through offsets.46 in collars 41, 42 and consequently holds these collars against rotary movement. These rods 45, however, .are formed with notches Use that when moved longitudinally the requisite distance the notches will come oppositethe offsets 46and permit the collars 41, 42 to rotate around the

bars

1, 2 and locking belts or rods 45. When the locking rods 45 are in their locked position they may be so held by catches 48 secured to the collars 41 and engaging rings 49 formed on rods 45 and embracing

bars

1, 2. For the better support of the cross bar 33 its ends are turned downwardly as shown at 33 over the said offsets of the collars 42, thus holding the bar 33 agains t longitudinal movement and avoiding the possibility of the ends thereof slipping out from between theoffsets 46 and guards 38'. The collars 41 42 are split or divided as indicated at 429011 the collar 42 as an example, so that they" may be in-" sorted over the side bars 1,2 and embedded therein to prevent them fioin moving longitudinally thereon, the divisions of the collar being afterwards secured-together by a nut and bolt 42 or. other suitable means. Having thus described m'y'invention what claim as new therein and desire to secure by Letters Patent, is
