Specification of Letters Patent.
Patented Apr. 28, 1914.
To all whom it may concern Be it known that I, ALBERT E. MoGlLL, 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 Perambulators or Go-Carts, of which the following is a specification.
This invention relates to improvements in folding perambulators or go-carts and more particularly to that class comprising a hinged frame for supporting the seat, a running gear frame on which a foldablebody structure is su oortcd and foldin wheel supports or forks adapted to fold under the runing gear frame when not in use, and the invention has for its primary object to provide improved means whereby the raising of the handle will automatically lock the folding wheels in their operative position.
A further object is to provide improved means whereby the raising of the handle from its folded position will automatically unfold the body structure and simultaneously lock the folding wheels in their operative position.
A further object is to provide improved means whereby the body structure brace may be utilized as a lock and brace for the wheel forks or supports.
A further object is to provide an improved device of this character having an adjustable, flexible back for the seat and improved means for maintaining the back under tension.
A further object is to provide an improved device of this character having an adjustable flexible back and improved means for taking up the slack of the back.
A further object is to provide improved means for locking the back in its adjusted position and improved means for locking the take-up device.
A further object is to provide an improved device of this character which will be simple and cheap in construction, effective and eflicient in operation and which may be folded or collapsed into a compact space when not in use.
To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings, illustrating an exemplification of the invention and in which Figure l is a side elevation of an improved device of .this character constructed in accordance with the principles of this invention.

Fig. 1 l is a detail sectional view on line 1 r14 of Fig. 13. Fig. 15 is a detail perspectiveview of the nut or sliding member which connects the upper end of the seat supporting brace to the body structure.
Referring more particularly to the drawings, the same reference numerals designate similar parts throughout the several views.
In this exemplification of the invention, the running gear frame comprises spaced side bars 20, preferably connected at their forward ends by means of a cross bar 21, which extends transversely across the frame and is offset as shown in Fig. 2 at a point intermediate its ends and between the side bars 20 so that the offset portion will project forwardly beyond the extremities of the side bars 20.
Rota-tively mounted on each of the side bars 20, preferably adjacent each extremity thereof, are wheel supports or forks 22 which may be of any desired or suitable construction but preferably bifurcated or fork shaped, and ournaled within the bifurcated portion of these wheel supports are suitable wheels. The wheel supports or forks 22 on each of the side bars 20 are respectively connected so as to simultaneously rotate about the side bars 20 when either of the forks is moved, in any desired or suitable manner, preferably by means of a connecting bar or member 23, the extremities of which may be secured in any suitable manner to the inner arms of the supporting forks or members 22. These connecting bars or members 23 are preferably located below and spaced from the side bars 20 and se cured thereto and preferably at points adjacent the rear wheel supports or forks 22 are clips 24% for a purpose to be hereinafter set forth.
Any suitable means may be provided for holding the wheels and the supports or forks thereof in operative position, such as a hook or member 25, one end of which is preferably pivoted to one of the connecting bars or members 23 and the free extremity thereof is bent into a suitable hook shaped portion, which latter is adapted to engage a suitable clip 26 on the opposite bar or member 23. A foldable body structure embodying a frame for supporting the sides of the seat is provided, and this frame preferably comprises spaced side bars or members 27 which are pivotally connected in any suitable manner to the forward end of the running gear frame preferably to the cross bar 21 and said body structure is adapted to assume an inclined position, the free end of which is located preferably adjacent the rear of the running gear frame. The rear end of the body structure is supported by means of braces 28 which are pivoted intermediate their ends to suitable collars or supports 29, which latter are secured to the side bars 20 of the running gear frame. The lower extremities 30 of these braces 28 project below their points of pivotal support 31 and also extend below the side bars 20 of the running gear frame and terminate at points adjacent the connecting bars or members 23 of the wheel supports or forks 22 and the lower extremities of the depending portions 30 are connected together by a cross rod or brace 32. hen the the braces are in an upright position to hold the seat support elevated, the lower extremities or depending portions 30 thereof will pass between the clips 24: and the connecting members or rods 23 of the wheels supports or forks 22 and lock the wheel supports or forks in their operative position. The connecting bars or cross rod 32 of the braces 28 enables the braces to resist lateral movement of the wheel forks without necessitating the braces being constructed of objectionably heavy or thick material. t suitable handle 33, preferably comprising spaced side arms and a connecting cross bar 34, is pivotally connected in any suitable manner to the rear end of the running gear frame, preferably by means of a transverse rod or bar Pivotally connected by one end to each of the side bars 33 of the handle and at points preferably remote from the pivot point of the handle is one end of a link 36. The free end of the link is pivotally connected to the upper or free end of the respective brace 28 in any suitable manner, preferably by means of a nut or member 37. A rod or bar 38 is spaced from and se cured to each of the side bars or members 27 of the seat frame in any suitable manner, preferably by means of clips or ears 39 and the nut or member 37, which pivotally connects the brace 28 and the link 36, is provided with a suitable aperture 40 through which the rod or bar 33 passes and when the braces 28 are moved about their points of pivotal support 31 in a manner to be hereinafter more fully set forth, the nut or member 37 will have a sliding movement on the rod or bar .38, which will cause the seat frame to be raised or lowered about its point of pivotal support on the running gear frame according to the direction of movement of the braces 28. Any suitable means may be provided for holding the nut or sliding member 37 in position to pivotally connect the link 36 and the brace 28, preferably screw threads on the portion of the member which projects through and beyond the link and brace, which threaded portion is adapted to receive a suitable nut 41. With this construction, it will be noted that when the handle 33 is moved from the position shown in full lines in Fig. of the drawing about its point of pivotal support 35 to the position in dotted lines in said figure, the link 36 will move the upper or free ends of the braces 28 forwardly toward the front of the running gear frame, causing the braces to move about their point of pivotal support 31, which will move the connecting brace or cross rod 32 and the lower extremity of the depending portions 30 of the brace rearwardly to the position shown in dotted lines in Fig. 5, which will cause the depending portions 30 to move out of engagement with the clips 24.
As the upper ends of the braces 28 move forwardly the free ends of the side bars 27 of the body structure will be raised slightly to permit the free ends of the braces to pass forwardly, as shown in dotted lines in Fig. A continued forward movement of the handle 33 will cause the nut or member 37 to slide on the bar or rod 38 which will tend to draw the side bars 27 of the seat frame downwardly toward the running gear frame after the free ends of the braces have passed their highest point during their forward moven'ient. VJhen the side bars 27 are in close proximity to the side bars 20 of the running gear frame, the handles 33 may be moved farther forward and folded upon the running gear frame, as shown more clearly in Fig. st of the drawing. The wheel supports or forks 22 may then be folded under the running gear frame.
A seat 1-2 is supported by suitable springs 1-3, which latter are secured to cross bars 14, which extend transversely across the running gear frame and are secured by their extremities to the side bars 20 of the running gear frame, and said seat i2 is of such a. width as not to interfere with or obstruct the movement of the side bars 27 of the body structure when the latter is folded against the running gear frame.
The body structure may be locked in its operative position in any desired or suitable manner, preferably by means of a locking frame which in this exemplification of the invention comprises spaced side arms 45, which are connected at one extremity by means of a cross bar or member 4-6, and the free extremities -17 of the side bars 455 are pivotally connected to the respective side bar 27 of the seat frame as at 4:8. This looking frame is preferably provided at a point adjacent the connecting bar 46 with notches or recesses it) preferably one being located in the under face of each of the side bars 45, and these notches or recesses d9 are adapted to pass over a suitable transverse bar or rod 50, which is secured to the handle 33 and extends across the space between the sides of the handle and said locking frame is of such a length that when the seat supporting frame and the braces 28 are in an operative position, the notches or recesses 49 will pass over the bar 50 and lock the handle together with the brace 28 of the seat supporting frame against further movement.
The seat 12 is provided with an adjustable, flexible back 51 which may be constructed of any suitable, flexible material. hie end of the back 51 is secured adjacent the seat 4:2 in any suitable manner, preferably to a transverse bar or red 53, the extremities of which are deflected or bent down ardly and offset and secured to the side bars 20 of the running gear frame. The offset portion of the bar or rod 53 is so arranged as not to interfere with the pivotal movement of the seat frame and is of such a height as to stand adjacent the top of the seat 12.
Any suitable means may be provided for supporting the upper end of the back 51 and for maintaining the back under tension and to take up the slack thereof, and in this exemplilication of the invention the improved means preferably comprises a suitable spring roller 54, the ends of which are mounted in suitable brackets or supports 55, which latter are mounted for sliding movement upon. the side bars d5 of the locking frame. The free end of the back 51 is secured to the roller 5 1 in any suitable manner and the spring is so arranged as to cause the adjacent end of the back to be wound upon the roller and said roller is of such a length as to extend substantially across the space formed between the free ends of the side bars :27.
Any suitable means may be provided for locking the roller 5st to maintain the back 51 at the desired tension and in this exam plification of the invention the roller 54 is preferably provided with a plurality of radial teeth 56, which are preferably located adjacent each end of the roller and also adjacent the inner faces of the side bars 415. A suitable dog or pawl 57 is pivotally supported on each of the brackets or collars 55 and so arranged as to engage or stand with in the path of movement of the teeth 56 to lock the roller. The free extremities 58 of the dogs or pawls 57 which project beyond their points of pivotal support are preferably connected by means of a cross bar or member 59, which cross bar or member serves as a means for simultaneously moving both of the dogs or pawls 57 about their points of pivotal support and out of engagement with the teeth 56 to release the roller 5% and to permit the back 51 to be drawn off of or unwound from the roller 54; or to permit the spring in the roller to wind up the back 51 according to the necessity. Any suitable means may be provided for supporting the free ends of the projecting portions 58 of the dogs 57 so as to hold the dogs into engagement with the teeth 56 on the rollers and in this exemplification of the invention suitable lateral projections 60 are secured to each of the extensions 58 and said projections are adapted to rest in suitable slots or recesses 61 in the upper faces or edges of the side bars 45 of the locking frame. Any suitable number of these recesses or notches 61 may be provided and are adapted to coiiperate with the projection 60 to permit the angle of inclination of the back 51 to be adjusted. In Fig. 5 the back 51 is shown in a position to cause the occupant of the carriage to assume a sitting or an uprightposture but when it is desired to Vary the angle of inclination of the back,
all that is necessary is to swing the dogs or pawls 57 about their points of pivotal support on the brackets or sleeves 55 to the position shown in dotted lines in Fig. 10 and then draw the brackets or sleeves 55 together with the roller 54 rearwardly to the position shown in dotted lines in Fig. 1 and then release the free ends 58 of the dogs or pawls 57 to permit the projections 60 to enter the desired notch or recess 61. During this rearward movement the back 51 will be unwound from the roller 54. lVhen it is desired to fold or collapse the perambulator from the position shown in Fig. 5, the dogs or pawls 57 are first moved out of engagement with the teeth 56 on the roller 54 in the manner as already set forth, that is, by raising the cross bar or member 59 and throwing it forwardly over the roller 54. When the roller is thus released, the tension of the spring therein will tend to wind the back 51 on the roller to take up any slack. \Vhen the roller is thus released the locking frame may be raised about its points of pivotal support 48 with the side bars 27 of the seat frame and thrown over to the position shown in dotted lines in Fig. 5 until the side bars 45 engage and rest upon the supports 27 on the side bars 27. WVhen the locking frame has assumed this position, the sleeves or brackets 55 will move by means of gravity and also under the influence of the spring in the roller 54 on the side bars 45 to wind up the back and take up the slack therein, as shown in Fig. 5. The handle being thus unlocked, the seat frame may be folded upon the running gear frame in the manner already set forth and as the seat frame is lowered, the spring in the roller 54 will cause the back to be wound on the roller and when the seat frame and handle have assumed the folded position as shown in Fig. 4 of the drawing, the cross bar 50 be tween the side bars 33 of the handle will enter and rest within the recess 49 of the side bar 45.
A suitable foot rest is supported by the running gear frame in front of the seat 42 and said foot rest preferably comprises a back portion 62, a bottom 63 and a front portion (34. The free end of the back 62 is secured to the seat in any suitable man her or if desired, may be constructed of and be a continuation of the same material which covers the seat. The free end of the front 64 may be supported in any suitable manner and in this exemplification of the invention, a suitable supporting bail having side arms 65 and a. connecting member 66 at the front end thereof is provided and the free ends of the side arms 65 are preferably deflected inwardly or toward each other as at 67 and said deflected ends 67 are pivotally supported on the bottom of the seat 42 in any suitable manner, preferably by means of suitable bearings 68. The free end of the front portion 64 of the foot rest is secured to the connecting portion 66 in any suitable manner and said connecting portion is of such a length that the side arms 65 will be suitably spaced from each other to permit the feet of the occupant to rest upon the bottom 68 of the foot rest and the said arms 67 are of such a length that the connecting portion or member 66 will rest upon and terminate short of the front of the offset portion of the connecting bar 21 at the front of the running gear frame. The foot rest is suspended by this bail or frame so as to depend below the running gear frame to accommodate the feet of the occupant when in a sitting or upright posture. WVhen the back 51 has been adjusted to allow the occupant to assume a reclining position, the foot rest may be adjusted or elevated to the position shown in dotted lines in Fig. 5 so as to elevate the feet to permit the occupant to assume a comfortable position.
Any suitable means may be provided for supporting the foot rest in its elevated position and in this exemplification of the invention there is shown suitable clips or supports 69, which are preferably secured to the side bars 27 of the body structure in any suitable manner, such as by means of screws or bolts and these clips or supports are so arranged as to project inwardly from the inner face of the side bars 27. The bail or support for the foot rest is preferably of an elastic construction and when it is desired to secure the foot rest in its adjusted position, the side arms (35 may be sprung slightly in- 'ard to permit them to pass the clips or sup ports 69 when the bail or supporting frame is raised, and when they have passed the clips or supports the pressure thereon may be released to permit the side arms 65 to assume their normal position and when the bail or supporting frame is lowered, the side arms 65 will engage and be supported by the clips or supports 69 as shown more clearly in Fig. 12 of the drawing.
