TONGUE-SUPPORT.

Specification of Letters Patent.

Application filed December 16, 1909.

Patented Dec. 31, 1912.

Serial No. 533,413.

To all whom it may concern:

Be it known that I, JOHN S. KURTZ, a citizen of the United States of America, residing in Earl township, county of Lancaster, and State of Pennsylvania, have invented new and useful Improvements in Tongue- Supports, of which the following is a specification.

This invention relates to carriages and wagons and particularly to tongue supports.

l/Vhile the classification is such that the invention is regarded as a tongue support for carriages and wagons, it is the prlmary object of this invention to produce a support for tongues of mowers, harvesting'machinery or the like, but as the invention 1s capable of use in many connections, I do not wish to be limited in that regard, and therefore would refer to the invention hereafter as a tongue support, meaning thereby a support for a tongue which may be used in many difierent connections.

This invention has particular relation to a tongue support designed as an improvement on a tongue support patented to moon Sept. 26, 1905, the patent number being 800,377.

The object of this invention is to provide means for permitting adjustment of the supporting members vertically and also to permit a certain oscillation or transverse movement of the arms to which the wheel is connected in order that the said wheel may change its course of travel as the tongue moves from side to side when the vehicle is being guided or turned.

Furthermore, it is an object of this invention to provide a colter wheel and the arms for connecting it to a tongue in which the arms are resilient and in which adjustment is provided for increasing or diminishing the tension of springs which are a part of the arms.

A still further object of this invention is to provide a member interposed between the arm and the tongue, the said member having a serrated surface designedto engage a serrated surface on an extension of the arm or the spring thereof, whereby, when the parts are clamped together, accidental disengagement or dislodgment of the parts with relation to each other may be obviated.

The invention furthermore consists in the details of construction as well as in the arrangement and combination of parts to be hereinafter more fully set forth and claimed, whereby a tongue support is provided possessing advantages of efficiency and durability, and proving at the same time comparatively inexpensive.

In describing the invention in detail, reference will be had to the accompanying drawings forming a part of this specification, in which Figure 1 is a view in elevation of a fragment of a tongue with the invention applied thereto; Fig. 2 is a detail view showing a fragment of the spring of an arm and a fragment of the member interposed between the arm and the tongue detached; Fig. 3 is a front view in elevation of a portion of the tongue with two spring members applied thereto.

In these drawings, 7 denotes a tongue having a socketed bracket 8, on the sides thereof, each of which is designed to receive a shank of an interposed member 9, to which the end of a spring 10 is connected, the said spring being formed integrally with an arm 11, designed to be connected to the spindle 12, on which a colter wheel 13 is rotatable; the manner of connecting the arms to the said spindle being an immaterial detail of construction which will not be described specifically, although the parts may have the same relation as they occupy in the illus tration in my patent above identified. The interposed member is curved and the face thereof is provided with a groove which forms a seat for the end of the spring and in order to insure the proper joint between the spring and the curved portion, I prefer that the said curved portion shall have a series of transversely disposed teeth or serrations 14, which may extend a portion of its length. The parts just described are secured together by a clip 15, and when the teeth are interlocked, it follows that the parts will retain their positions of adjustment until released.

The shanks of the interposed members are of course rotatable, or partially rot-atable in the brackets, and therefore the springs oscillate when the colter wheel is in contact with the ground, and the tongue is moved sidewise.

I claim v1. In a tongue support, a member for connecting the tongue support to a tongue, an interposed member oscillatingly mounted with relation to the member on the tongue, the said interposed member having a serrated portion, an arm having a spring serrated to correspond with the serrated portion of the interposed member and means for mounting the colter wheel on the arm.

2. In a tongue support, members adapted to be connected to opposite sides of a tongue, an interposed member oscillatingly mounted with relation to each member on the tongue, the interposed members being provided with serrations, springs having serrations corresponding to the serrations of the interposed members, adjustable means for binding the springs to the interposed members whereby the serrations hold them in position, arms outstanding from the springs, and a colter wheel mounted on the arms.

3. In a tongue support, a member for connecting the tongue support to a tongue,

an interposed member oscillatingly mounted with relation to the member on the tongue, the said interposed member having a serrated portion, an arm having a spring serrated to correspond with the serrated portion of the interposed member, a clip extending around the serrated spring and the serrated portion of the interposed member, means for tightening the clip whereby the spring and the interposed member are held in adjusted position and means for mounting the colter wheel on the arm.

In testimony whereof, I affix my signature in the presence of two witnesses.
