WHlFFLETREE-COUPLENG.

SPECIFICATION formingpart of Letters Patent No. 257,171, dated May 2, 1882.

Application filed August 29, 1881.

To all whom it may concern Beit knownthatl, HENRY A. LUTTGENS, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Whiftlet-ree-Oouplings; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention is an improvement upon a whiftletree plate and clevis for which Letters Patent of the United States of America were granted to me January 1, 1878, No. 198,771.

It consists in an improved mode of fastening the clasp which holds the whiffletree in contact with the pin-formed side of the clevis, which clasp is not fastened to the whiffletree in the same manner as before, but has the form of a cap united to the bars which enter a recess made in the face of the whiflietree. The bars at their ends are united by a cross-bar, which has an opening to receive a bolt. The end ofthe bolt near its head is shaped to fit this opening, and the bolt-head is reduced in width to that of the bars above mentioned. The bolt itself enters a hole made in the center and bottom of the recess in the whiftletree and passes entirely through the same, being secured by a nut in the rear. By reversing the bolt it can be made to enter the rear of the whiftletree, in which case the cross-bar of the cap is provided with a boss, which forms the nut. A

wearing-plate, the same as shown in the original patent, is inserted into the whifietree, be-

in g placed across the recess in the face of the whiftletree; also, a packing'holder with ears to support the whiffletree, similar to that shown in the original patent, is provided with a large cavity for holding the rubber packing.

In the accompanying drawings, Figures 1 and 2 are front and rear views of part of a cross-bar and whiffletree of a carriage, united by the improved device. Fig. 3 represents a section through the middle of the same, and Fig. 4 the pin formed side of the clevis, in sec tion. Figs. 5, 6, and 7 represent the cap, bolt, and wearingdate in detail, and Figs. 10, 11, 11%, and 12 modifications of the same. Figs. 8 and 9 represent plan and section of the packing-holder.

B represents a portion of the whiffletree,

(No model).

and A a portion of the cross-bar of a shaft to which the whiftletree is secured.

Olevis G is secured to the cross-bar A by bolt 1 and by screw 0, the latter inserted in an elongation of the rear end of the clevis (J and below the bolt 1.

The packing-holder G is secured to the top of cross-bar A, and is provided with ears on n, which may be bent to suit the position of the whiftletree B. This packing-holder contains a short rubber tube, 01, by means of which and the ears m n the whiffletree B is supported.

A wearing-plate, k, is inserted into the face of whifflet-ree B, which bears against the pinshaped part c of clevis O. For the purpose of uniform wear, and to avoid ridges forming upon the pin 0, it may be made with flattened sides, as shown in Fig. 4.

A washer, w, is inserted into the top of whiifletree B and placed so as to bear against the under side of the upper part of the clevis G. The washer 10 may be made of Babbitt or anti-attrition metal, and provided with a small oil-hole at the top which does not eutirely pass through the washer, or it is made of lignum-vitoe, so placed that the end of the grain of the wood acts against the wearingsurface 21, provided at the under side of the upper part of the clevis G.

The bars 00, m, and y, forming part of cap 3, fit into a recess, z, made into the face of the Whittletree B. Bolt a, which enters cross-bar y, passes through the whiffletree B, and is secured by a nut, f, thereby uniting and securing together cap 8, pin 0, wearing-plate 70, and whiffletree B. The slot 2 is made of such depth as to allow the cap 8 to be drawn toward the whiftletree. The cap 8 and bars at, w, and :1] form together an opening large enough to admit the pinformed side 0 of the clevis 0, plus the wearin g-plate 7c, and the head of bolt a. The open= ing must also be of asize to pass over the end of the clevis 0.

To put together the parts which enter the slotted hole in the face of the whiffletree, it is necessary that the difference between the opening within the upper part of clevis O and the width of whifiietree B is at least equal to the thickness of the head of bolt a, plus the thickness of cross-bar The clasp which holds the whiffietree in con tact with the clevis, in the manner as shown Fig. 11%; also, if desired, two bolts like a inin the patent above referred to, does not restead one may enter the bars as 00, side by side, main firmly secured when in use, nor is it cain which case the cross-bar 3 may be dispensed pableof adjustment after being loosened upon with, the bars 00 00 being made round and en- 25 5 the pin by wear or otherwise, which defect larged toform thenutsforboltsa; also,washer I is overcome by the peculiar construction of z, placed and of a shape as shown, may be cap 8, which, by means of bars 00, w, and y, (221- made of steel tempered so as to act as a spring; tends to the rear of pin 0, and by bolt a can also, thefwearing-plate k may be widened, as be readjusted, so as to bear securely upon the shown in Fig. 12, as much as the opening be- 30 1o pin-formed part c of the clevis (1, thereby enatween the bars as :0 will admit. bling the cap .9, pine, wearing-plate 7c, and What I claim as new'is-- Whiffletree B to remain united by adjustment In a whifiietree-coupling, thecombination of until the parts are so worn as to become usea clevis having the wearing-pin a, with the cap less. 1 75, inserted in the face of the whififletree, ad- 3 5 15 Amodificationofthe mode ofoonnecting the justing-bolt a, and cap 8, arranged and opercaps and bolt a is shown in Figs. 10, 11, and ating substantially asset forth. 115- where that part of cap 8 which is formed t w 1 T by ross-bar y is made to form the nutfor bolt a, LUT'lGEL the head of the bolt being placed on the outside Witnesses: 20 and rear of whiffletree 13.
