FOLDING CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 571,228, dated November'lO, 1896. Application filed June 1, 1896. Serial No. 593,720. (No model.)

To all 1117mm, z t 'I77/(I/Z/ concern:

Be it known that I, FREDERICK HEPPNER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Collapsible and Folding Carriages, of which the following is a specification.

My invention relates to a new and useful improvement in collapsible carriages, and has for its object to provide a device of this description which, when in use, will have the and differ therefrom in no essential feature, and yet when occasion requires may be fold ed into a small compass for transportation or change in a quick and simple manner.

\Vith these ends in View my invention consists in the details of construction and combination of elements hereinafter set forth,a11d then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction and operation in detail, referring to the accompanying drawings, forming a part of this specification, in which Figure 1 is a central longitudinal section of a carriage embodying my improvement when the several parts thereof have been placed into position to produce the ordinary carriage. Fig. 2 represents the general appearance of my improvement when folded for transportation or storing; Fig. 3, an end View of the body; Fig. 4, a detail perspective showing the method of securing the foot-board and sides of the body together; Fig. 5, an enlarged detail section showing the method of securing the foot-board to the bottom of the body; Fig. 6, a detail perspective of the handles. Fig. '7 is a detail elevation of one of the detachable axles, showing the method of securing it to one of the side-bars and the metallic crossbar; Fig. 8, a similar section at the line a: w of Fig. 7 looking in the direction of the arrow; Fig. 9, a detail section of the hub of one of iug the same upon its axle; and Fig. 10, a side view of a portion of this hub.

Referring to these drawings in detail, 1 represents the body of the carriage, which is com-- posed of a bottom board 2, sides 3, head i, and foot-board 5. These parts may be of such shape as to produce any desired design or carriage when properly secured together, and the sides, and head and foot boards are attached to the bottom by a series of hooks 6, which are secured thereto in any convenient manner,the noses of which are adapted to enter the slots in the plates 7, said plates being attached to the foot-board, as clearly shown in Fig. 5, where one of these hooks and plates is illustrated in the manner of their initial engagement, it being of course understood that suitable recesses 8 are formed beneath the plates to receive the hooks when passed through the slots.

A number of lugs 9 project from the ends of each of the sides, head-board and foot-board, and when these parts are brought together the lugs are so positioned as to come in line with each other, when they are secured by the passage of the pins 10. These lugs may be formed with the several parts from which they project, and when the body of the carriage is made of cane or other suitable material the lugs may be formed by the proper interweaving of said cane. Thus to form the body from the several parts the sides are first attached to the bottomby bringing first one side and then the other into substantially the same horizontal plane with the bottom, engaging the hooks 6 with the plates 7, and swinging said sides upward and inward until the lower edges abut against the bottom, which will prevent further inward movement, and when the head and foot-boards have been similarly attached the several parts are secured rigidly together by the passage of the pins 10 through the holes in the lugs 9, as before described.

To the bottom of the body are attached in the usual manner the springs 14, the lower ends of which are also attached to the side bars 1.5, which form a part of the truckframe, and these bars are secured together parallel with each other by the metallic crossbars 16. Thus the bottom of the body and the truck-frame are inseparable, and when the carriage is folded the several parts thereof fall within the dimension of this" bottom and frame, as clearly shown in. Fig. 2.

Four axles 17 are provided and are arranged TCO to be attached to or detached from the truckframe by each having an upwardly-curved extension 18, through the upper end of which passes the bolts 19, having threaded on its end a thumb-nut 20. Slots 21 are formed in the cross-bars 16, and having enlargements 22, so that the nuts may be passed through said enlargements, and when the axles are drawn inward the bolts 19 will pass into the slots 21, when they may be clamped by tightening said nuts, thereby securing the upper ends of the axles, the lower portions of which are rigidly connected to the side-bars 15 by the brackets 23, each of said brackets being composed of two levers pivoted together at 24 and terminating in jaws 25, adapted for engagement with suitable notches formed in each of the axles. The upper ends of the levers which compose the tongs terminate in hooks 26, arranged to engage with the plates 27, secured upon the side-bars by passing through suitable slots therein, recesses 27 being formed in said bars back of the plates to permit the entrance of the hooks.

To secure the axles to the truck-frame, the operation is to first engage the jaws 25 of one of the brackets with its axle, and then pass the hooks 26 into engagement with the plates 27 by turning them sufficiently sidewise, and then moving them inward to the perpendic ular, and finally clamping the upper end of said axle to the cross-bar 16, as before described. Each axle having thus been secured to the truck-frame it will be seen that they will be firmly held in place until again detached by the reversed operation. The handles 28 are secured to this truck-frame by the angle-irons 29, which are permanently attached thereto and adapted to fit upon the ends of the side-bars 15, and there held by the passage of suitable pins 30; and in order that these handles may both be rendered rigid as respects to sidewise strain, and also securely held in their proper relative position to the truck-frame, I arrange a truss 31, which consists of two parallel wires and two wires running diagonally, which connect these parallel wires, and at their meeting-points are arranged the screws 32, which pass through suitable holes in suitable wires, two of which are adapted to be screwed into the holes 33 and the remaining two into holes formed in the side-bars, and for convenience these screws are so arranged as to remain with the truss-frame when the latter is removed from the handles. A handle-bar 34 is provided with threaded holes 35, by means of which the handles are attached thereto by screwing the threaded tips 36 within said holes, and this isdone previous to the attachment of the handles to the truck-frame.

Each of the wheels consists of a rim 37, having the spokes 38 attached thereto in the ordinary manner, and these spokes have formed upon their inner ends heads 39, for the purpose next explained. 40 and 41 are disks having radial holes 42 formed therein, through which the inner ends of the spokes pass and areprevented from withdrawal by the heads The disk 40 has a square opening through its center adapted to fit snugly upon the squared portion of the hub 44, and is also provided with an annular recess facing outward, which is threaded for the reception of the threads 45 of the nut 46, and said nut is pro vided with ears 11. The hub 44 is of tubular shape and adapted to fit over one of the axles 17, and is also provided with a tubular extension 47, upon which the nut 46 turns. The outer end of the hub is enlarged, as at 48, the perimeter of which enlargement is squared, the interior being circular. The disk 41 is provided with a squared recess adapted to fit over the end of the enlargement 48, and when so fitted the wheel is securely held to the hub by turning up the nut 46, which draws the plate 40 away from the plate 41, thereby drawing tension upon the spokes.

Each of the tubular hubs is held in place upon the axles by the pins 48 and 49. Thus when a wheel is to be secured to one of said hubs the disks 40 and 41 are passed over said hub, the enlargement 48 being of less diameter than the squared portion 43, thereby permitting the disk 40 to pass the enlargement 48 without hindrance, and when these disks are in proper place upon the squared portions of the hub they are there secured by the engagement of the threads of the nut 46 with the threads in the disk 40, as before described. The removal of the wheels from the axles is very simple, and requires but little time, in that it is only necessary to back off the nut 46, when the disks 40 and 41 will be free to be disengaged from the hub, and may be brought into contact with each other, thus reducing the thickness of the wheel, and this is permitted by the slots 42, in which the inner ends of the spoke slide, when the relation of the disk is changed.

The rear wheels of the carriage are preferably made somewhat larger in diameter than the front wheels, which permits the smaller to lie within the larger, and the diameters of the latter are such that they may lie upon the bottom board 2 of the body without extending beyond the edges thereof when the carriage is collapsed; and in collapsing the carriage the several parts thereof are so folded and arranged that all the loose members may be packed into the space between the bottom of the carriage and the truck-frame, and when thus packed they are covered with the canvas strips 50 and 51, there being two of the former secured to the inner surface of the bottom near the side edges thereof and two of the latter likewise secured near the ends of said bottom when the carriage is formed for use. These strips of canvas lie upon the bottom thereof, and there serve for a covering for the floor of the carriage, or may be concealed by suitable strips of carpeting superimposed thereon, and when the carriage is collapsed any surface of the bottom of the body becomes the outer surface of the package.

The side strips 50 are drawn upward around the several parts contained Within the pack age and passed beneath the side-bars 15, when their meeting edges are secured together by the strips and buckles 52, the end strips having previously been folded over the package and afterward secured in place by the strips and buckles 53, all of which is clearly shown in Fig. 2. hen thus folded and secured, the package becomes a solid piece of package that can be safely shipped by railway or carried in the hand by means of straps and handles. (Not shown.)

In collapsing the carriage the operation is as follows: The parasol 54, which is of any ordinary construction and supported by the curved rod 55, is taken out. The pins 10, each made of wood or other suitable material, are withdrawn from the lugs 9, when the head and foot boards and sides of the body may be removed from the bottom by the disengagement of the hooks 6 from their plates, the seat of course having previously been removed and folded. The handles are next detached by removing the truss-frame 31 and the pins 30, and these handles maybe disconnected from the handlebar by unscrewing, as before described. The removal of the axles from the truck-frame is accomplished by unscrewing the thumb-nuts 20 and moving them toward the central enlargement 22 in the metallic cross-bars, then passing the thumbnuts through these enlargements and pressing the wheel downward to disengage the hooks 26 of the brackets from their respective plates, after which these brackets are disengaged from the axles by their jaws being swung upon the pivot-points 24, as before described; and, finally, the four wheels are each removed from the axles, leaving the hubs and nuts 46 thereon, and by bringing the disks 40 and 41 in contact with each other these wheels are then ready for placing upon the bottom board of the body, after which all the detached parts are placed upon this board and covered and secured in place by means of the canvas strips, as hereinbefore set forth.

I am aware that various designs may be produced and slight modifications might be made in the construction here shown and described without departing from the spirit of my invention; and I therefore do not wish to be limited to these details of construction, one modification of which might be in the substitution of hooks 26 for holding the brackets 23 to the side-bars 15.
