UNITED STATES CHARLES o. JOHNSON, OF SOUTH GARDITNER, MASSACHUSETTS.

IMPROVEMENT IN TOY-CARRIAGE S.

Specification forming part of Letters PatentNo. 131,688, dated'September 24, 1872; anteda ted September To all whom it may concern:

Be it known that I, CHARLES C. J OHNSON, of South Gardiner, in the county of Worcester and State of Massachusetts, have invented an Improvement in Toy-Carriages, 850.; and I do hereby declare that the following,

taken in connection with the drawing which riages. The invention has reference, first, to

the construction of the body; and consists in formingthe' body with rounded corners by using for each corner joint a connector having a curved outer face and a diagonal inner face, the diagonal inner face being innermostiand facing the inside of the body and having two grooves or mortises, into which the ends of the adjacent boards fit and enter. "The invention has-reference, secondly, to the manner of connecting a third or leader wheel to the body; and consists in han ging the opposite ends of the wheel axle or gudgeons in bearings in the ends of curved cast-metal arms, the opposite ends of such arms being formed with horizontal top faces to fit against the under surface of the Wagon or carriage body, a clamp-plate being provided with two grooves or recesses, into which the two straight parts of the arms fit, the clampplate being screwed against or up toward the bottom of the carriage-body and clamping the bearings or axle-supporting arms tightly in position. a g

The drawing shows, in bottom view and in side elevation, a carriage-body embodying my invention. r

a denotes the front board; I), the rear board; 0 c, the two side boards; and d, the bottom of the body. 6 denotes one of the two rear wheels f, the leader or third wheel, the two wheels 0 running on the opposite'ends of an axle, g, fastened directly to the bottom of the body, while the front wheel f turns on an axle-pin the opposite ends of which are supported in bearings in the ends of arms h, these bearings being holes bored, or cast in the ends of the arms in line with the axle. The two arms h h are cast independently, and each is curved and has at its end opposite the axle-bearing a straight arm, c, at the outer end of which is a projection, is. The straight arms '5 being placed against the bottom of the carriagebody,,a clamp-plate, Z, is placed over them, (recesses m in the plate fitting over the arms 6,) and the plate being screwed to or toward the body, the bearings are thereby fastened in position. By means of the movable bearings the axle may be adjusted in position for the wheel to run easily and correctly, and the arms may then be fastened by the clampplate. Furthermore, by thus making the bearing-arms they have to be cast only with the axle-pin holes, (one in each,) instead of with such holes and holes to fasten the bearing to the body. Connecting the two adjacent ends of the front and side boards, and side and rear boards, at each corner of the body, is a corner piece, a. Said piece is a quarter-round on its outer surface,'the two opposite sides of the curve'running tangentially into the adjacent surfaces of the body-boards, and at each end of the curve is a square shoulder,

o, from which extends a groove or mortise, p, the adjacent board being made with a shoulder, q, to fit against the shoulder o, and a tenon, r, fitting into the mortise, the inner surface of the corner piece or connector being diagonal, or extending straight across from tenon to tenon, as seen at s. -Theshoulders, tenons, and mortises being all formed to tightly and accurately fit the boards, are joined by the connectors, and, being glued together, need no nails or other fastenings to make them secure; and the corners of the body are smooth and freefrom fastenings,

which are liable to get loose and form catches by which clothing will be torn. At 0 I show the joint enlarged, and at D a modification, in which, by making the outer surface of the connector with a swell, t, the edges of the boards a. b c are keptof full thickness, the mortises which the edges enter being made of such width that the edges fit into them.

I claim 4 the boards fitting thereinto, substantially as 1. The axle-bearing arms h h, formed as shown and described. shown and described, and secured to the bot- CHARLES C. JOHNSON. tom of the body by the clamp-plate l. Witnesses:
