JARS OF TRAVEL ARE
 OBVIATED BY SPRING
(From Saturdays Daily)

An automobile spring, the invention of local boy, promises in the near future to add much to the comfort of those riding in gas-propelled vehicles. Letters of patent have just been re ceived from Washington and the in ventor, Robert C. Hartin, and his f. rancial packer, Austin " Mulvenon, leave for Detroit next week to meet one of the leading manufacturers of vehicle springs and automobiles in the United States and consummate ar engagements for the placing of the spring on the market on a royalty basis. The product of the brain of young Hartin should result in a for tune not only for himself and also for Mir. Mulvenon.
 The new spring differs from the ones now found in automobiles in nine different ways, but its two most valuable points are its non breakability and the floating" motion it produces. It has been the common experience of every one who nas ridden in an auto to have had his head vigorously bumped when the machine struck rut or any other obstacle in the road. This was the result of the up and down motion from the springs, the same motion being responsible for drivers losing control of their cars and also for the cars skidding. To this cause most auto accidents are at tributable. But with the new spring the motion resulting from striking a bump or other obstruction is forward instead of skywards, described as the floating" motion. Another material advantage is that in the event a spring should break, contingency hardly likely, the bed of the machine could not possibly sag, or sink down on the axle and interfere with the steering gear.
 The object of the inventor was to produce a spring that was simple in construction, compact and durable and uniformly distribute the jar incident to travel and avoid fracture of the spring leaves. It is said by experts that the same principle can be used in the construction of locomotive springs with marked success.
 In the usual construction, the spring is clamped rigidly to the axle of the vehicle, and should one end or the other of the vehicle body tilt up and down it forces the full weight of the body upon one end of the spring which may thereby sustain a fracture or injury.
 To overcome this there is provided a plurality of spring leaves having centrally disposed and laterally pro jccting Jugs and housing which is connected to the axle of the vehicle, the housing having correspondingly shaped sides which engage the Jugs or the spring leaves and prevent lon gitudinal displacement, at the same time allowing a tilting motion to the spring relative to the housing, where by the spring adjusts itself to the lev el of the supported body and the strain is equally distributed to the ends of the spring. The structural arrangement is such that while the spring leaves are held in loose con tact with the housing or support, they effectually maintaim their efficiency as resilient support for the body.
 A housing opens at each end with outwardly bulging sides and inwardly arcned top and bottom plurality of spring leaves disposed in said housing and resting on top and bottom, and semi-circular Jugs on the spring leaves engaging with the side.
