GOLLAPSIBLE CARRIAGE.

To all whom it may concern Be it known that we, CHRISTOPHER S. Srorronn and FREDERICK W. J ones, citizens of the United States, residing at Sturgis, 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.

The main objects of this invention are: First, to provide an improved collapsible carriage in which the body collapses compactly by a single collapsing movement or motion. Second, to provide an improved collapsible carriage which is simple and economical in structure and mechanism, and at the same time, one which is strong and durable.

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

. We accomplish the objects of our invention by the devices and means described in the following specification.

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

A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a perspective view of a structure embodying the features of our invention, the upper part of the handle being broken away. Fig. 11 is an inverted or bottom view. Fig. 111 is a detail vertical section on a line corresponding to line 3-3 of Fig. 11. Fig. 1V is a perspective view of the structure collapsed. Fig. V is .a detail side elevation with the axles and wheels and seat removed, parts being shown in their collapsed position by dotted lines.

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

Referring to the drawing, the frame in the structure illustrated, comprises side members 1 and a front cross piece 2 formed integrally of a flat bar bent into U-shape. The side members 1 are connected by cross pieces 3 on which the seat 1 is mounted.

Specification of Letters Patent.

Application filed May 9, 1913.

Patented Mar. 2%, 191st.

Serial No. 766,548.

The back 5 is pivotally mounted on the ears or brackets 6 on the seat to fold forwardly thereon. At the front of the seat is a flexible boot portion 7.

The front supports 8 are connected to the front axle 9 and their upper ends have a sliding connection with the frame, the connection preferably consisting of pins 10 on the supports 8 which engage longitudinal slots 11 in the side members 1 of the frame, as shown.

The upper ends of the rear axle supports 12 are secured to the side members of the frame by the pivots 13 and to the rear axles by the spring members 11-. These spring members are of the blade type and given a quarter twist at 15 so that their front ends lie flat against the supports 12 and are are pivotally connected by the pivots 17.

Thus connected to each other and to the frame, the supports are adapted to collapse, allowing the frame to drop down on the axle between the wheels, as shown.

The supports are erected and held in their erected position by means of the levers 18 which are mounted on the pivots 17 and slidingly connected to the side members of the frame, the connection preferably c011- sisting of the pins 19which engage longitudinal slots 20 in the side members, as shown. This permits the levers being swung forwardly, allowing the supports to collapse and when the levers are swung to their rearward position, the supports are extended and supported in their extended position. The levers are preferably actuated from the handle 21 which is pivoted at22 to the rear ends of the side members of the frame to collapse forwardly, as shown. in Fig. IV.

The levers 18 are connected to the side members of the handle by means of the links 23 which constitute side bars for the carriage body, the flexible sides at being supported by the levers and these side bars or by the links 27 to the levers so that when forward in the slots, as stated, and as shown by dotted lines in Fig. V.

'The back is supported by means of the bail 28' which is pivoted at 29 to the links 23, the cross bar portion of the bail being engaged with a strap 30 011 the back of this seat. See Fig. III. By thus supporting the back it may be adjusted at different angles relative to the seat, and when the structure is collapsed, is folded forwardly upon the seat.

To add to the rigidity of the structure, the supports are connected and braced by the cross piece 31 which is disposed between the support pivots.

Our improved collapsible carriage is very economical in structure as there are relatively few parts and these are simple and economical to produce and easilyassembled.

The structure is light, but at the same time, is rigid and durable.

We have illustrated and described our im provements in detail in the form in which we have embodied the same for the market. We hai e not attempted to illustrate or de scribe modifications in structural details as we believe the disclosure made will enable those skilled in the art to which this invention relates to embody our improvements as conditions may dictate. We desire, however, to be understood as claiming our in vention specifically in the form illustrated as Well as broadly within the scope of the appended claims.
