TONGUE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 368,392, dated August 16, 1887.

Application filed September .21, 1886. Serial No. 214,192. (No model.)

To aZZ whom, it may concern:

Be it known that I, ISAAC W. HAMMON, of Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in \Vagon Tongue or Shaft Supports; and I do hereby declare that the following is a full, clear,and exact description thereof, reference bein ghad to the accompanying drawings, and to the letters of reference marked thereon,which form a part ofthisspecification.

This invention relates to improved spring supports for the tongue or shafts of vehicles.

The invention consists in the matters hereinafter described, and pointed out in the ap pended claims.

Figure 1 is a longitudinal vertical section taken through the front axle of a vehicle and a spring-support attached thereto, said view showing the tongue and thcspring-arm in side elevation. Fig. 2 is a sectional elevation taken upon line :0 a: of Fig. 1, showing the supporting arm or spring in section and the attaching devices for pivotally connecting it with the axle in elevation. Fig. 3 is a fragmentary sectional view similar to Fig. 1, showing another form of device embodying-the main features of my invention.

In the said drawings, A indicates the front axle of the vehicle, B B the hounds, and G a tongue or pole pivoted between the front ends of the hounds at c in the usual manner.

D is the supporting arm or spring of the tongue-support, which is connected by a pivotbolt, (1, with vertical lugs E, secured to and projecting in front of the axle and extends forward beneath the tongue to a point in advance of the pivot c of said tongue.

E is a setscrew inserted through a part or projection upon the axle and bearing upon the springarm D in such manner as to prevent the free end of the latter from dropping, while at the same time affording means for raising and lowering the said free end of the arm, so that the latter may sustain the front end of the tongue in a higher or lower position,as desired. In the particular form of the device shown in Figs. 1 and 2 the said spring-arm D is formed by a series of leaf-springs, d d d cl", secured together by bolts or rivets d' d", the upper spring or layer, (1, being bent upwardly and formed into an eye, (1, through which thepivot-bolt d is inserted. In this instance the vertical lugs F, between which the inner end of the spring-arm D is placed, and through which the pivot-bolt d is inserted, are cast integral U against the under side of the spring-arm D forward of the pivot d. The plate orlug F is desirably cast or otherwise made continuous with the lateral plates or lugs F, so as to give the necessary rigidity therein without giving too great weight to the parts. This construction obviously affords the necessary support to and adjustment in the spring-arm without any complicated or expensive construction in the parts to attain these ends.

Another desirable construction whereby the main features of the invention may be carried out is shown in Fig. 3. In this example the spring-plates d d d d, composing the springarm D, arebolted or riveted at their inner ends to a casting, D,having an upwardlyextending part or arm, D which is located between lugs F upon a plate, F, and pivoted to said lugs by a pivot-bolt, (Z, inserted through the lugs and through an aperture in the upper part of the said ar'm D The adj UShlllg-SCIGW' E is in this case arranged horizontally, and is inserted through a downward]y-extending part or prolongation, f, upon the plateF in such manner as to bear upon the rear or inner face of the casting D. The said set-screw in this con struction obviously operates in adjusting the position of the free end of the spring-arm D in the same manner as before stated.

In the application of a spring'support of the character above described to a wagon or carriage having shafts the spring-arm of the support will be attached so as to bear upwardly upon one or both shafts, or upon the connecting-bar between them in a manner readily understood.

I am aware that it has been proposed heretofore to employ for a wagon-tongue support a spring-arm pivotally connected with the outer ends of the hounds by a depending yoke or bar and provided with a short arm extending past its pivotal point and adjustably connected with the tongue itself near the pivot of the latter. I am also aware that a spring-arm consisting of a series of thin connected plates has been rigidly attached to the end of the reach forward of the axle and extended over the top of the tongue and connected with the latter at its outer end. A tongue-support pivotally attached to the axle and extending beneath the tongue,in combination with an adjusting device attached to lugs secured to the axle and acting upon the spring-arm near its pivotal point, as herein shown, has obvious and important advantages in point of simplicity and rigidity over supports of the kind heretofore made, and above referred to.

I claim as my invention- 1. The combination, with the axle and pivoted tongue or shafts of a wagon-gear, of vertical lugs F F, secured to and proj ecting in front of the axle, a spring-tongue-supporting arm pivoted between said lugs, and an adjusting screw, E, supported by the axle and bearing upon the spring arm, substantially as described.

2. The combination, with the axle and the tongue or shafts of a wagon-gear, of a supporting device for said tongue or shafts, consisting of a plate or casting,F,secured to the front surface of the axle and providedwith vertical lugs or projections F F, a spring-arm pivoted between said lugs or projections, and a set screw threaded through the said plate or casting and bearing upon the spring-arm, substantially as described.

In testimony that I claim the foregoing. as my invention I affix my signature in presence of two witnesses.

his ISAAC W. x HAMMON.
