IMPROVEMENT IN SPRING-WAGON sears.
The Schedule referred to in these Letters Patent and making part of the same.
'Be it known that I, JAcOB I. BEAR, of Decatur, Macon county, State of Illinois, have invented a new and useful Improvement'in Springs for a Wagon-Seat; and I do hereby declare that the following is a full and accurate description of the construction and operation of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.
My invention consists of an improvement in the method of attaching springs to wagon-seats, and rendering adjustable the lever-supports used therewith, and is an improvement upon the invention of John H.
, Hale intended-for a similar purpose.-
In the annexed drawing- A represents a cross-beam secured to the upper side of two spring-strips B B, whichare in turn secured to two bars I) I), attached to the underside of the seat, near its ends.
C G, 860., represent four spring-slats, two upon either side of the seat, which are secured together in pairs by a cross-bar, c, at their outer ends.
The inner ends of the slats O 0, 8m, rest in wedge; shaped notches c 0' made upon the upper side of the bar A, and are firmly-heldtogether and in place by means of two staples of metal D D, which pass downward through suitable holes'in the ends of said slats, their lower ends projecting below said slats upon each side of the bar A.
E E represent two cross-bars secured to the under side of the seat, and resting upon the slats C 0, forming lever-supports for said seat. It being evident that as said supports are moved to or from the bar A, the stiffness of the springs will be diminished orincreased, it becomes desirable to so attach them to the seat as to permit of the ready adjustment, in orderthat the strength of the springs may be easily proportioned to the weight upon said seat.
To accomplish this object, said supports are secured to the bottom of the seat by means of screws passing through slots, extending lengthwise of said seat,'into the supports.
The slots are of sufiicient width' only to permit the body of the screw topass, so that if the latter is screwed down until the head binds, any degree of ti ghtn'ess can be secured, and the supports rendered easy or more difiicult of adjustment. I
v The advantages claimed for these improvements are- First, the staples DD furnish not only a secure, but also an elastic connection for the inner ends 9f the springslats O 0, so that if the outer ends of said slats are confined by the sides of thewagon-box, and prevented from spreading laterally when the seat is depressed, the inner ends of said slats may be allowed to come nearereachother, and thus compensate for the fixedness of the opposite ends.
Second, the means employed for adjusting the leversupports, and for securing them to the seat-,render it easy to proportion the strength of the springs'to the weight in the seat.
I am aware that the combination and arrangement of the spring-slats B B and O O, and adjustable leversupports E E with the wagon-seat, are the invention of John H. Hale, and, therefore, do not claim such; but
I do claim, and desire to secure by Letters Pat- The staples D D, passing through and securing together the spring-slats C O, &c., in combination with
