Specification of Letters Patent No. 3,159, dated July 8, 1843.

To all 'whom t may concern Be it known that I, H01L-ion 7001), of Greenwich, in the county of Tashington and State of New York, have invented a new and useful Improvement in lVagons and Carriages; and I do hereby declare the following is a full and exact description.

The nature and principle of my invention consists lst in arranging the spokes in the wheels so as to prevent the rim from bending in at the joints by dividing the felly` into eleven parts and putting the spokes about two parts from the ends which makes a short space where the joints are, and long in the center as represented by `Figure l, in the accompanying drawings; 2d, in making the axletrees less liable to break or spring down by making them on the principle of an arch as shownby a back view in Fig. 2. I run an iron tension rod on a straight line under the axletree and entering the wood so as to come out at the center of the ends of the arms as at receiving nut washers on the ends as shown at bb l) in Fig. 6, which serve both to hold the wheels on and as abutments to keep the axletree in its arched position. I band the ends of the arms so as to fill the small box and let wear irons in for the large box. 3d, in fastening the shafts 7L 7L, or pole firm into the axletree on an angle so that the axletree will be plumb when the horses are attached and to give free play in all directions to the front axletree and prevent wear and friction I connect it to the` carriage part or gearing by inserting a ball and socket joint at a Fig. 6 similar in principle to the hip or shoulder joint in the human frame, with this dif-` ference the socket incloses the ball o Fig. 2 about of its surface so as to prevent its slipping out; the ball I make of cast or wrought iron andform a short neck to it the diameter of which is about of that of the ball and connect with this neck a bed plate of a suitable size to rest on the axletree take a nut underneath as shown at o Fig. 2. The socket I make in two halves of cast iron or other hard metal as light as possible and have sutlicient strength with a bed plate corresponding with the one attached to the ball with ears or flanges as at a Fig. 3 to receive the bolts to hold it together. I make the hole in the socket larger than the neck of the Vball and oval, the longest way fore and aft so as to admitv the ball to roll in the socket and give motion to the shafts or pole up and down. Fig. 4L is a top view of socket when together sho-wing the bolt holes to fasten it to the head block. I fit the socket into the head block or bolster and fasten it with bolts headed in the bed plate and running up through the wood. Fig. 5 is a back view of socket and head block; when together, it`

mortises toreceive the perches. (The head block may be made of cast iron for small work.) 4th, in the place of one perch and braces I use two perches and frame each into the back axletree about ten inches from the center as at c o Fig. 6 running forward and in onta curved line o-f about inch to the foot and entering the head block about six inch es apart as at CZ d for light work; on the inside of these I fasten iron straps forged round at the ends and passing them through both axletree and head-block I fasten them with nuts as at ec ce. I fit in abllock where the perches come the nearesttogether and bolt through the whole as at f; these straps when tight prevent the perches from springing in, and to prevent their springing out I pass an iron tension rod g g through on a straight line outside of each perch and fasten with nuts the same as the strap. For lumber work straight porches can be used without rods.)
