Specification of Letters Patent.

Patented Oct. 14,1913.

Application filed. November 13,, 1911. Serial No. 660,029.

To all whom it may concern.

Be it known that I, ELLswonrH B. OvnnsHixnn, 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 Gro-Carts, of which the following is a specification.

My invention relates to improvements in go-carts, or childrens buggies, and has especial reference to vehicles of this class which are capable of being folded into small compass into a receptacle or box.

One of the objects of my invention is to provide a structure which when unfolded and extended affords a very complete, practicable and effective childs buggy or gocart, possessing all of the desirable features of the more rigid structure of this character, and capable of being readily and conveniently folded into a receptacle which is a part of the structure, and when sofo-lded, presenting the appearance of an ordinary suit case.

Other and further objects of my invention will become readily apparent to per sons skilled in the art from a consideration of the following description, taken in conjunction with the drawings, wherein Figure 1 is aperspective view of the device unfolded, and showing all of the parts in operative position; Fig. 2 is a vertical sectional view of the device, as it is shown in Fig. 1; Fig. 3 is a similar view to Fig. 2, showing the seat depressed and the back inclined at a greater angle, and with the hood thrown forward; Fig. d is a longitudinal, sectional view with one side removed; Fig. 5 is a transverse section taken on line 55 of Fig. d; Fig. t: is an enlarged, fragmentary detail of a part of the frame of the buggy top, or hood. Fig. 7 is an enlarged detail of the frame-supporting clip, secured to the sides of the buggy box; Fig. 8 is an enlarged view of a part of the buggy frame; Fig. 9 is an enlarged, fragmentary detail of the vehicle handles; Fig. 1 0 is a perspective view of the device as it appears when the gear and top are folded into the case, and the closure in place on the box part and latched.

In all of the views the same reference characters indicate similar parts.

A suit case, or box-like structure, in which the device is to be inclosed, is shown in Fig. 10, wherein 1'0 is the box or body part of the structure, and 11. is the closure or top, the latter being flanged all around by a overlying part- 12. The

latches

13, 13 hold the body and top part together when in closed position, and 14 are corner protecting pieces usually found on suit cases. 15 is a handle secured to the side, by which the case may be carried. The top 11 is hinged to the body or box-part at one end, as at 16, by strap hinges, the

members

18, 18 of which are secured to the outside surface of the body part, and the cooperating straps 17 17 are angulated, as at 19, and secured to the inner lining of the top part 11. From the upper end of the strap 17, projects a lug 20, to which is hinged a folding

link comprising members

21 and 22, each of which is pivoted to an intermediate overlying link 23, to permit folding of the links .21 and 22 in the same vertical plane. The lower end of the link 22 is pivoted to a clip 2 1, as at 25, which clip is secured to the inside vertical wall of the body part of the structure. This link structure prevents the top from swinging too far rearwardly and holds the top in position in which it has been placed when the links 21. and 22 are in the same longitudinal plane. There are two such link structures connecting the top and body part of the device, one on each side, and they hold the top, with reference to the body, at the proper angular position, and prevent its rearward movement and also hold it from being moved until the joint between the

links

21 and 22 and the intermediate member 23, respectively, is broken, and by this means I am enabled to utilize the top as the connecting medium between the handle, by which the device is propelled, and the body art. p The handle 26 is preferably composed of a bar of wood, or the like, which extends across the top, and is adapted to be folded into the top of the case, as shown in Fig. 4, or to be extended and fixed above .and out-- side of the case, as shown in Fig. 2. 1t consists of a forked bracket 27., on each side of the top, of which only one is shown, secured to the back of the top, by rivets as at 28, and having a forwardly projecting member 29, provided with a turned-over portion 30, which serves as a stop for the pivot arm The arm 32, to which the handle 26 is directly attached, is an angulated portion of the arm 31, the part 31 abutting against the art 30, when the handle 26 is in its extended and operative position. The arm 32 is pivoted to the bracket extension 29, as

at 33, and on this pivot the handle may be turned when it is desired to fold it within the top or interior of the structure.

A latch 34 is pivoted, as at 35, to the arm 32. Tt has a swinging movement, limited by the pin 36 and the slot 37. When the latch is placed in the position shown in Fig. 9, with its lower end 39 abutting the bracket 29, the arm 32 can not then be turned on its axis, but when the latch 34 is moved outwardly, as is permissible by the pin and slot, by pressure upon the thumb piece 38, then the arm 32 is free and it can be moved upon its axis to return to the inclosure. There is a structure of this character on each side of the top and the handle 26 connects the two structures, so that the handle will be held positively and firmly in extended position.

The running gear is adapted to be folded into the box 10. It consists of four wheels, two on each side. The wheels on each side are connected together in fore and aft pairs, and are moved into the casing as one. To the extended long ends, 4041, 4041 of strap hinges are secured laterally and outwardly projecting studs upon which

wheels

42, 42 and 43, 43 are rotatably secured. The hinge members 40-41, 40 41 are connected together respectively by

straps

44, 44. The straps 44 have each an inwardly projecting, angular part 45, which is perforated for reception of a latch member 46. The latch member 46 is a stud, that passes through the bottom of the box 10 and is secured to a spring strap 47, the latter being secured to the bed as by rivets 48. An angulated part 49 extends upwardly along the side of the interior surface of the side of the bed, and is provided with a thumb piece 50 which projects inwardly and laterally from the vertical angulated piece 49. When the part 49 is lifted against the resiliency of the spring 47, the latch member 46 is raised out of engagement with the angulated part 45 of the strap 44. V

The stud 46 is slightly tapered, as clearly shown in Fig. 5, so that when the strap portion 44 is pressed inwardly toward the bot tom of the box, the stud 46 snaps into the orifice, provided in the angulated piece 44, and by this means the gear, on each side of the body, is properly held in vertical operative position. The

hinge members

40 and 41 are secured to their respective cooperating

hinge members

51 and 52, in hinged or pivoted relation, at the upper edge of the body or box.

Throughout the entire specification wherever parts are duplicated I have marked the corresponding parts with the same reference characters distinguished by the exponent prime. I will, therefore, refer specifically toonly one part.

The freely movable hinge member 52, is

hinged to another fixed member 54, the latter being securely fixed to the side of the box, so that the member 52 may swing inwardly when the gear is placed within the receptacle body. When the wheels are folded within the receptacle one set may be placed near the bottom, as shown in Figs. 4 and 5, in which event the gear structure will turn upon the lower, fixed hinge point of the member 52, and the other set of the gear structure will then turn upon the upper joint of the member 52, thereby permitting one set of wheels to be placed lower in the box than the other by the operation of this compound-hinge structure.

The seat portion of the vehicle is composed of the bottom 55, and the back 56, the latter being hinged to the former as at 57, at a point somewhat in advance of the rear edge-portion of the seat. The seat 55 is secured to a hinge member 58, which in turn is pivoted to a member 59 which is equivalent in length to the height of the sides of the box part of the structure, and the part 59 in turn is hinged to a part 60, which is secured to the bottom of the box, so that in its raised position the seat 55 will be in a longitudinal plane substantially equivalent in height of the sides of the box, as shown in Fig. 2.

An arm 61 is hinged to the back 56, as at 62, Fig. 2, and to a'substantially vertical link 63, as at 64, the said link being hinged to the bottom 55 as. at 65. The lower portion thereof extending beyond the hinge 65, is provided with two outwardly extending, button-headed

studs

66 and 67. The headed

studs

66 and 67 are adapted to engage in

notches

68 and 69 provided in the clip 70. The clips are secured to the sides of the boxpart of the body, and are the'mea-ns by which the front portion of the seat 55 is supported when the seat is in raised position.

The links 63 are provided with slots 71 through-which a retaining leather strap 72 passes for holding the infant in place on the seat.

three convergingbows, 73', 74 and 75, and the foldable extendible link structure, composed of member 76, hinged to the bow 73, as at 77, and link member 78 hinged to the bow 75, as at 79, each of the members being hinged to a clip 80, as at 81 and 82, whereby the members 76 and 78 are held in alinement when the device is extended, and by means of which the members may be folded together in the same plane when the bows are brought into folded position. The bows converge to a central point and are hinged to a clip 88, as at 84, 85, and 86, respectively. The clip 83 is slotted, as at 87, and carries an outwardly projecting stud 88. A bracket 89 is secured to the arm 61, as by rivets 0r screws 90, and extends in a Vertical The hood of the vehicle is composed of position for engagement with the clip 83. A screw 91 passes through the slot 87 of the clip. 83 into. the vertical bracket 89. In the upper end of the vertical bracket is a notch 92 for reception of the stud 88. By this means the hood as a whole is firmly held in vertical position, as shown in Fig. 2', when the stud 88 engages the notch 99.. W hen it is desired to move the hood bodily at an angle to the position shown in Fig. 2, it is only necessary to lift the hood, the slot 87 permitting such movement, until the stud 88 is lifted free of the notch 92 when the hood may be moved on the pivot screw 91 to any position desired. Any suitable fabric may be employed. for providing a cover forthe hood, suchv as shown at 98.

lhe child may be seated in the vehicle in an upright position, or in the position shown in Fig. 2, and it may be permitted to occupy a recumbent position when the parts have been shifted until they occupy the position shown in Fig. 3, in which latter figure the hood 93 has been brought forward to shade the eyes of the child from the effects of the sun, or too strong a light.

It will be observed that when the parts have been unfolded, so to speak, and occupy their respective positions, the structure thus formed is strong, durable, and in accordance with recognized mechanical principles, and that when folded and placed within the box part of the receptacle, the entire mechanism is concealed therein, leaving no evidence upon the outside of the receptacle as to the contents thereof.

While I have described a single embodiment of my invention for the purpose of complete disclosure, it is evident that many changes may be made therefrom without departing from the spirit of my invention and within the scope of the appended claims.
