Specification of Letters Patent No. 842, dated Ju1y 16, 1838.

To all whom it may concern Be it known that we, JOSHUA JoNEs, ALAN M. Firms, and HORACE Gmswono, of the county of Delaware and State of New York, have invented a new and Improved Mode of Applying or Adapting Coiled or Spiral Springs to Carriages of Pleasure or Burden; and we hereby declare the following to be a full and exact description.

A spiral spring similar in its construction to the main spring of a watch, inclosed in a.

barrel or cylinder of any convenient diameter, is fixed on axes near the middle of the perch of the carriage. From the periphery of the barrel containing the spring, and from opposite sides thereof two bands are extended one passing to the front and the other toward the rear of the carriage, each of which bands is attached to the end of a lever passing downward from a cross piece or bar passing across each end of the wagon above the axletree and parallel with it. At each end of these cross pieces or bars is also a shorter lever or arm passing toward the middle of the carriage in a direction at right angles (or nearly so) with the downward lever before mentioned. To these shorter levers or arms the carriage body or box is attached at each corner, by a connecting rod and shackles, or if thought preferable by thorough braces. The levers passing downward from the before mentioned cross bars, and to which the bands passing from the before mentioned spiral spring are attached, are longer than the arm projecting from the same bar to sustain the carriage, by which means the spring operates with increased power on the projecting arms for sustaining the body of the carriage. On the lower end of each downward lever is fixed the segment of a circle of which the lever is the radius, by which means the action of the spring is made more equal, the connecting band being kept at all times equidistantfrom the upper end or fulcrum of the downward lever. The cross pieces to which the arms and levers are attached rest upon perpendicular supports or standards of iron or other material, at each end of the bolster or axletree, and move upon their axes on the supports or standards as influenced by 1 the VlbIEliLIOHS of the spiral spring of the carriage. On one end of the cylinder con-.

taining the spiral spring, is placed a ratchet wheel and catchdesigned for winding up'the spring to any degree of tensionthat may be required for sustaining eitheifa' lightor a heavy burden.

Two or more spiral springs may be employed lnstead of one for heavy CELIIIHgGS,

either by placing more than one spring in the barrel, or by placing any number of barrels on a connecting shaft, in which case a corresponding number of connecting bands will be required.

What we claim as our invention and de sire to secure by Letters Patent is- The combination of the mode of hanging the carriage body (by means of the axles, arms, downward levers, &c-.) with the spring or springs constructed and operating substantially as herein described, and also, in combination therewith, the mode of regulating the tension of the spring or springs in manner as herein described.
