JOHN HERRON, OF OLNEY, ILLlNOlS.

THlLL-COUPLING.

LZECIFICATION forming part of Letters Patent No. 306,749, dated October 21, 1884.

Application filed March 21, 1834. (No model.)

To all whom t may concer/t:

Be it known that I, JOHN Hannon, a citizen of the United States, residing at Olney, in the county of Richland and State of Illinois,

haveinvented certain new and useful Improve` ments in Shaft-Couplings, of which the following is aspeciiication, reference beinghad therein to the accompanying drawings.

My invention relates to certain new and #n.ro useful improvements in Jchill-couplings; and

it -consists in arranging a series of devices to hold a pole or pair of shafts to the axle of a wagon, whereby either can be readily secured or detached, the parts held securely in place, and the connect-ions prevented. from rattling or becoming loose. j

The object of my invention is to securely attach the shafts or pele to the axle of a wagon in such a manner that they will notbecome 2o disconnected while in use, and that the connec tion and disconnection can be easily made at the will of the operator without the troublesome method of unscrcwing the bolts, as usual in the old way.

My invention further consists in providing means to hohl the parts in place, to prevent :noise caused by loose bolts and the danger l'roni breakage when loose. I attain these objects by means of the peculiar construction and arrangement of the various parts of my device, which will be more fully pointed out in the specifications and claims, reference being had to the drawings accompanying this application and forming part of the same, in Whicll-` Figure 1 is atop plan view of my invention, showing the parts locked in place., Fig. 2 is a perspective view of the same." Fig. 3 is a vertical sectional view, showing manner of connection. Fig. 4 is a detail view of curved spring, and Fig. 5 is a detail view showing connectingbolt.`

Similar letters refer to similar parts throughout the drawings.

Referring to the drawings, A represents an end and a groove, d, cut in the opposite end, as shown in Fig. 5. Said bolt E is formed to fit loosely in the perforations in the ears a, andin the shaft or pole end B, and when put in place the angular end c fits snugly over the sides and upper face of one of the ears a, as shown in Figs. l and 2. The object of this, construction is to conne the bolt E exactly in place and in preventing its displacement when in use; and, further, it is easily inserted and removed. A curved spring, D, is formed with a spoon-shaped outer end, and a short distance inward are formed angular projections d, that extend outward over the upper face of ears a, as shown in Figs. l, 2, and' 4.. Said ears a Vform bearings against which the under face of said projections rest, to prevent the spring from being drawn downward by its tension. One side of spring D is formed to rest one of projections d/ on the upper face of the angular projection c of bolt E, as shown in Figs. l and 2. A projection, c, having an inclined outer face and a dat angular inner face, is secured to the inner face and inner end of the spring D, thepurpose of 'which is to hold the outer end of spring D away from the inner f end of shaft B and the angular upper face, c,

of bolt E, in order that the boltE may be readily removed. rlhe inner end of Spring D is formed ilat, with an elongated slot, d2, near its end, formed to fit over a bolt or projection,

j', extending from the end of the clip yoke or tie, said spring being held in place by a nut turned 011 said bolt f. rlhe purpose of the elongated slot is to permit of the vertical adjustment of spring D.

My peculiar forni of spring D is shown in Fig. 4, in which thc flat end is formed with an angular projection or catch, c, that holds the upper part of said spring back in the saine manner as shown in Fig. 2. An elastic wire spring, b, is attached by its inner end to the clip O, and its outer or free end is curved upward to rest in the groove d, formed in the end of bolt E, as shown in Figs. l and 2. This construction forms a safet f-spring to prevent the bolt E from falling vout should the spring D become loosened or broken.

Having described my invention, I claim and desire to secure by Letters Patent- 1. A shaft-coupler consisting of clip having perforated projecting ears, a-bolt provided IOO with an angular head l'ornied to lit the side@l and top of one of said ears, said bolt having an annular groove in its opposite end, a eurved s} iring1"or1ued to be held at one end rigidly or loosely against said clip, its free end curved rearward and formed with 'projections to lit the upper i'aee of the ears ol" the clip and the upper face of the bolt-head, Said spring being adapted to press against the inner end of a perforated shalt or pole iron, substantially as shown.

2. lin a Shaft-coupler, a curved .Spring with its inner end centrally slotted, and provided with an end angular catch pi'oieetion adapted to receive and hold the edge of said spring, its outer end curved backward and provided with side projections, substantially as and for the purpose Set i'orth.

2). A Shafteoupling bolt l'orined with an nngular head adapted to fit over the Sides and top of' the projecting' ears ol' an axle-clip7 the opposite end ol' said bolt being provided with an annular groove, substantially as shown.

-.l-. In a Sl1ai't-coupler, the bolt E, having an angular head and grooved opposite end, as shown, a curved wire spring, one end secured lo the shaft-clip andthe opposite end pressing within the groove in the end of" A@aid bolt7 substantially as Shown.

5. n a shaft-coupler, the axle A, having clip C, provided with projecting ears u, the shaft B, the bolt E, having angular head c: and groove d, as shown, and the catch e, in coinbination with the spring D andthe wire spring I), arranged and operated subsi antiall y as shown and Specified.

ln testimony whereof I al'lix my Signature in presence oi" two witnesses.

JOHN l lllltltON. Witnesses:
