IMPROVEMENT IN ATTACHING THILLS TQ AXLES.
Specification forming part of Letters Patent No. 36,559, dated September 30, 1862; antedated August 19, 1862.
vented certain new and useful Improvements in Attaching Thills'and Poles of Carriages to Axles; and I do hereby declare the following to be a full description of the same.
The nature of my invention consists in secnring the thills and poles of carriages to the axles by means of a screw-bolt (secured at one end by a center pin passing through ear-pieces formed on the end of the thill-irons) inserted through a mortisehole in the jack, so that by tightening up the screw-nut on the lower end of the bolt the thills will be firmly and securely held in contact with the jack, and by tightening up the screw-nut as the parts in contact wear away always keep them from rattling without the intervention of any rubber or other packing; but to describe my invention more particularly I will refer to the accompanying drawings, forming a part of this specification,
the same letters of reference, wherever they occur, referring to like parts.
Figure '1 is a side view of the thill and jack as secured to the axle-tree. Fig. 2 is a longitudinal cut section of the same. Fig. 3 is a detached front view of the end of the thill-irons and screw-bolt. Fig. 4 is a detached front View of thejack.
Letter A is a representation of the thill of a wagon, having on the lower end of it the thilliron B, secured by the usual means of screwbolts to the thill. In the lower end of the thilliron, between cheek-pieces O C, is secured, by means of a center pin, D, a screw-bolt, E. This screw-bolt is made square for a portion of its length. so as to fit a square mortise, F, in the jack G. The object of this is to hold the thills firmly in the jack and at the same time prevent them from having any sidewise motion,as would be the case if the bolts were made round. The j acks are formed of blocks of metal having depth enough to give a substantial support to the bolt passing vertically through the mortise.
To compensate for the wearing away of the cheek-pieces of the thill-irons on the bearings with the bearings of thejack to keep them from rattling. It will be obvious from this that the office of the screw-bolt is to draw and hold the thills and jack together, but does not form the bearing upon which they work, so that by making the axis of the bolt eccentric to the center of the cheek-pieces on the thill-irons (as it is intended in a practical working model) it will allow of a largeamount of wearing away of the metal before the nut on the lower end of the bolt will'cease to be effective in compensation for such wear by drawing the axis of the bolt within the cavity of the jack.
Letter J is the jack-bar or holder, forming an extension at the back side of the jack, so as to attach it to the axle K by means of the clip L and nut M on the ends of the clip.
It will be obvious that the jack may be connected with the clip in various ways; but I do not deem any such modified application of it a material change of the arrangement described.
Havingnow described my invention, I will proceed to set forth what I claim and desire to secure by Letters Patent of the United States- 1. The longitudinal arrangement of the bolt E with reference to the thills, in combination with the thill irons B, substantially as described, and for the purposes hereinbefore set forth.
2. The jack having a mortise longitudinally through it, in combination with the bolt E and thill-irons B, substantially as described, and for the purposes hereinbefore set forth.
3. The use of the recess H, formed in the sides of the mouth of the mortise in the jack, substantially as described,an'd for the purposes hereinbefore set forth.
LYMAN DERBY.
