UNITED STATES PATENT OFFICE.

OORYDON NORTON, OF ALBION, PENNSYLVANIA.

CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent No. 251,274, dated December 20', 1881.

Application filed April 28, 1681. (No model.)

To all whom it may COTIOM'II Be it known that I, OORYDON NORTON, a citizen of the United States, a resident of Albion, in the county ofErie and State of Pennsylvania, have invented new and useful Improvements in Carriage-Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters or figures of reference marked thereon.

My invention relates tothe construction and arrangement of vehicle-springs.

The object of my invention is to produce a cheap, durable, and elastic spring for the purpose named.

My invention is illustrated in the accompanying drawings, as follows:

Figure 1 is a perspective view. Fig. 2 is a view showing a detail of construction.

A A are bars connecting the axles of the vehicle.

A A are cross-bars, which may be used or not, as desired.

B B and B B represent the body of the carriage or wagon.

It will be seen that the springs lie lengthwise ot' the carriage. They are composed of the following parts: 0 O are quarto-elliptic springs, but may be joined or formed of one D D are C-springs, formed by turning back the outer ends of the quarto-elliptic springs (l. E E are quarto-elliptic springs. F is a crankrod extending from one side of the carriage 'to the other, and on each side connects the springs E to the springs D in such a manner as to provide for a forward-and-backward movement of the carriage-body. Any of the springs O D E may be strengthened by extra leaves, if it is desired to do so. The springs (l and D are formed of one piece of metal, the spring D being bent back upon the spring 0, as clearly shown in the drawings,and then bent into proper form for a C-spring. On the loop formed by bending back to form the C-spring is placed a clip, 0, which is clearly shown in Fig. 2. This clip or clasp is put on and then bent down firmly, and holds the lower part of the C-spring D onto the upper part of the quarto elliptic spring 0.

Rivets might be used in place of the clip a, but they would weaken the material. If, however, rivets are used, the springs G and D may be of two separate pieces of metal; but I greatly prefer the construction shown.-

When the carriage is not heavily weighted the springs G and E will furnish all the elasticity required; but when the load is increased beyond their capacity the C-spring, which by its form is stiffer, will be brought into action.

When the carriage is not occupied the crank of the rod F will stand nearly horizontal; but as the load upon the springs increases it turns toward a vertical position. The crankrod also serves to permit an oscillation of the carriage-body longitudinally, which gives a.

pleasant effect, and when the carriage-wheels strike in a rut or against an obstruction it relieves the springs of the wrenching effect which would otherwise take place.

I am aware that a crank-rod similar in construction and for a similar purpose has been used, but in connection with springs having a ditferent form.

It is not essential to the operation of my springs that the crank-connection be a rod extending across the buggy.

This spring is capable of use in other than buggy or vehicle springs. It maybe used for a bed spring without any material change from the construction shown in the drawings.

What I claim as new isl. In a carriage spring, a quarto or semielliptical spring having at its outer end, upon its 'upper side, a C-spring facing outward therefrom, substantially as described.

2. In a carriage-spring, a quarto or semielliptical spring having at its outer end a 0- spring, bent backward and facing outward therefrom, formed of the same piece of metal, substantially as described.

3. In a carriage-spring, a quarto or semielliptical spring having a C-spring formed of 5 In testimony that I claim the foregoing I have hereunto set my hand this 18th day of lo March, 1881.
