UNITED STATES PATENT OFFICE.

GROVER EZRA. CLEVELAND, OF STURGIS, MICHIGAN, ASSIGNOR TO STURGIS STEEL Gro-CART COMPANY, OF STURGIS, MICHIGAN.

COLLAPSIBLE CARRIAGE.

To all whom it may concern:

Be it known that I, Gnomi: Eze. CLEVE- LAND, a. citizen of the United States, residing at the city of Sturgis, county of St. Joseph, State of Michigan, have invented certain new and useful Improvements in `Collapsible Carriages, of which the following is a specification.

This invention relates to improvements in collapsible carriages.

My improvements are particularly applicable to, and I have embodied them in practice and here illustrate them in, a structure of the type shown in the patent to Kurz, No. 866,145, of September 17, 1907 for collapsible carriages, although they may be modified and adapted for use in various other relations.

The main objects of this invention are: first, to provide in a collapsible carriage an improved means for actuating the collapsible wheel supports. Second, to provide in a` collapsible carriage an improved means for bracing the wheel supports when in their erected position. Third, to provide in a collapsible carriage an improved guard or fender whereby t-he wheels are guarded in their erected and also in their collapsed condition. Fourth, to provide in a collapsible carriage an improved adjustable and collapsible back.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The structure described constitutes one effective embodiment of my invention.

Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a side elevation of a structure embodying the features of my invention, the wheels on one side being removed and a portion of the top and handle being broken away. Fig. 2 is an enlarged detail side elevation showing the means for actuating the Specification of Letters Patent.

Application led August 30, 1909.

Patented Dec. 31, 1912.

Serial No. 515,206.

tical seetion taken on a line corresponding to line 5-5 of Fig. 4. Fig. G is a detail section taken on a line corresponding to line G-G of Fig. 5. tical section taken on a line corresponding to the broken line 7 7 of Fig. 2, showing details of the back supports. Fig. S is a detail section taken on a ine corresponding to line 8-8 of Fig. 7. ig. 9 is a detail horizontal section taken on a line corresponding' to line 9--9 of F 3. Fig. 10 is a detail section taken on a line corresponding to line 10-10 of Fig. 3 showing details of the back construction. Fig. 11 is a detail section taken on a line corresponding to line 11 of Fig. l.

In the drawing, similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, l represents the running gear frame which is preferably U- shaped in form. The handle 2 is pivotally secured to the rear ends of the side bars of the running gear frame by means of the pivots 3. On each of the side bars of the running gear frame are clip-like hangers 4 for the wheel supports 5. The wheel supports 5 are preferably Vformed of rods having downwardly projecting wheel carrying arms 6 thereon provided with suitable journals 7 for the wheels 8. The wheel supports are pivotally supported on the hangers so that they are free to swing therein to permit the wheels to be folded upon each other under the running gear frame.

The supports are erected and collapsed by means of a pair of levers 9 which are pivoted on the running gear frame at 10. The upper ends of the levers are connected to the handle by means of the links 1l so that the levers are actuated through the handle. The handle is adapted to swing forwardly upon the running gear frame when the structure is collapsed. The levers 9 are projected downwardly below their pivots and are Fig. 7 is a detail verpreferably offset inwardly as at 12, and connectedV by a cross piece 13, the cross piece serving as a brace therefor. In practice the levers are preferably formed of a single piece bent into a U-shape.

On the wheel supports are inwardly projecting lever engaging members 14C. These are preferably plate-like in form the same being preferably formed of sheet metal as illustrated. These members 14 are provided with lever engaging cam openings 15 and 16, the openings being of different shape so that one wheel support is actuated before the other. The cam openings 15 and 16 are preferably provided with slotelike eXtensions 17 adapted to receive the levers when the parts are in their erected position, thus t-he levers serve as braces for the wheel supports. rlhe wheel supports are held bot-h' in their erected and collapsed position.

The levers 9 are locked in their erected position and the wheel supports further braced by means of the braces 18 and 19 which are arranged in pairs and pivoted at 20 and 21 respectively on the running gear frame. These braces are connected by the

links

22 and 23 to the levers 9, the links 22 being pivoted to the rear braces 18 and the links 23 being pivoted to the forward braces 19. The pivots 24 for theV links 22 are arranged above the pivots 10 for the levers 9 while the pivots 25 for the links 23 are arranged below the pivots 10 so that the braces are actuated in opposite direction and are folded up under the running gear frame or swung into engagement with the clips 26 provided therefor on the wheel support arms 6. The rear braces 18 are preferably curved at their upper ends so that the pivots 27 thereof swing past the center of the pivots 20 when the parts are in their erected position, thus forming a locking toggle for the levers 9. The wheel supports are, by this arrangement of the parts, collapsed or erected through the actuation of the handle and also are effectively locked and braced in their erected position.

I preferably provide the wheels with fenders 28. The fenders also serve as guards for the wheels when they are collapsed. These fenders are supported on the wheel supports, the ends of the fenders being provided with Veshaped supporting brackets 29 mounted on the arms 6 of the wheel supports and the center with a strap-like hanger 30 mounted o-n the horizontal portion of the wheel supports. These supports 29 are arranged on the inside of the wheel as clearly appears in the drawing. As the wheels are collapsed the fenders are swung with them so that the wheels are properly guarded while the structure is collapsed which is of very great advantage as the cart can then be handled without the liability of soiling the garments of the person carrying the same,

projecting arms thereon which arms are piv,

oted on the side bars of the running gear frame at 21 as illustrated. This gives the seat a free pivotal movement and secures the full effect of the springs 33 which are arranged at the rear end of the seat. rThese springs are preferably coiled springs and are preferably secured upon the cross bar 34.

The back 85 is preferably adjustably supported and also supported to be automatically collapsed and erected upon the collapsing and erecting of the carriage. rlhis l preferably accomplish by providing the supporting members 36, which are secured to the seat to project upwardly at the sides thereof. llfhese supporting members are slotted at 37 to receive the pivots 38 for the back. The back is provided with downwardly-projecting segments 89 adapted to engage the pins 40 on the members 36, thus providing a slip connection for the back to the seat and segments for adjustably supporting the back. The teeth of t-he segments are projected forwardly so that the back can be automatically collapsed whatever its adjusted position may be.

To automatically collapse and erect the back I connect the same to the wheel actuating levers 9, preferably through the links 41 having slots 42 therein adapted to receive the pins 4:8 on the levers tt which are pivoted at 45 to the seat. rlhe upper ends of the levers are connected to the back through a slip connection preferably consist-ing of pins 4G arranged in the slots 17 of the levers. This permits the adjustment of the back and when the carriage is collapsed or erected the back is also collapsed or erected automatically.

The seat is preferably provided with flexible side portions 18 which are secured at their upper ends to the links 11 which, as stated, form the side bars of the seat. To draw these side portions taut when the carriage is erected and permit the collapsing of the carriage without applyingythe tension 0r stress to the side pieces l preferably connect their lower edges to the links 22 as by means of the straps L19. As these links are swung downwardly when the braces 18 are swung into engagement with the wheel supports they are firmly held so that they are not only effective for the purpose but have a neat appearance.

The back 36 preferably consists of a board-like body portion 50 provided with a front covering 51 and a rear covering 52, the front covering being provided with a suitable pillow 53. The edges of the covering are brought to the edges of the body and covered and secured by means of the U- shaped binding This binding is formed of metal and serves not only to secure the covering to the body, but also to reinforce the body so that it may be formed of thin material, the binding extending across the top and down each side of the body. rlhis binding also serves as a means for attaching the back supporting means described. To prevent the spreading of the binding I preferably provide a strap like cross piece which is arranged across the back, as shown in Fig. 3, and secured by arranging its hooked ends 5G through suitable holes provided tl'ierefor in the rear edgesl of the binding, see Fig. lO.

The foot rest 5T is preferably pivotally mounted on the seat bracket 3Q at 5S to be adjustably supported by means of the brace like support 59 which engages the cross piece l?) on the lower end ot' the levers. As the details of this :foot rest form no part of my present invention they are not further described herein.

The top 60 is adjustably mounted on the links ll, but as the details of this top form no part of my invention they are not further described herein.

I have illustrated and decribed my improvements in detail in the form in which I have embodied them in practice. I am, however, aware that they are capable of considerable variation in structural details with- 'out departing from my invention, and I desire to be understood as claiming the same .specifically as illustrated as well as broadly.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
