COMBINED SHAFT-SUPPORT AND THlLL-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 518,763, dated April 24, 1894.

Application filed November 18,1893. Serial lie-491,353. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM E. MURBAR- GER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in a Combined Shaft-Support and Thill-Ooupling; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertai-ns to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked 4 larged scale.

thereon, which form a cation.

My invention relates to improvements in shaft supports and thill couplings, and it consists in a combined shaft support, anti-rattler and bolt retainer for thill couplings combining in one compact device several novel and valuable features, which render the invention exceedingly convenient and efiective in practical use: and my invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, in which the same numerals of reference indicate corresponding parts in the several figuresz-Figure l is a perspective view showing my invention in its operative position. Fig. 2 is a perspective detail view, on an on- Fig. 3 is a front elevation of the spring and its roller." Figure 4 is aperspective detail view.

In the drawings, 1 indicates the tension plate, which is cast preferably in the form shown, having the curved neck 2 which extends up between the parallel arms of the clip, 10, and fits against the end of the shaft iron 11 which is pivoted between the clip-arms by a bolt 12. Shoulders, 3, 3, are formed on each side of the neck 2 which contact against the under side of the clip-arms, and prevent the tension plate from rising. In the side of the tension plate is formed a circular recess, 4, adapted to form a seat for the coiled inner end 5 of the spring 5; and a circular series of holes, 6, are formed in this seat into any one of which the extremity 5 of the spring, which is bent out at right angles to the plane of the coil, can be engaged. This circle of part of this specifiretaining apertures enables the end of the spring to be adjusted to arrange the set of the spring to carry the shaft at the desired height; and to always give the spring the desired strength or tension. One of my devices is of course attached to each of the two shafts of a vehicle, but it is only necessary to here illustrate and describe one of them. The outer free end of the spring is bent across at right angles, as shown, and upon this transverse end is mounted aroller, 7, thebarrel of which is of a width corresponding to the width of the shaft against the under side of which it bears, while at each end the roller is formed with the wide flange, 7 to prevent it from slipping from the shaft in actualuse, these end or side flanges fitting up on each side of the shaft, as shown. At about the center of its length the spring arm is bent, slanting, across the line of the spring coil, bringing its outer end in nearly the same plane with the inner end'of its coil, as clearly shown in Fig. 3; the object of this construction being to bring the roller 7 directly under the shaft, so that it will bear squarely against it and work successfully.

To the front of the tension plate 1, immediatelybelow its neck 2, is secured a slideplate 8, which is formed with the retaining end 8*, extending up in a plane at right angles to that of the slide. It will be seen by reference to Fig. 1 that when in position this retaining end will extend close on the outer side of the head of the pivot-bolt, 12, and will hold the said bolt securely in place, and ren der it impossible for it to work loose or come out: and dispenses with the usual nut on the pivot-bolt. The slide bodyis formed with an adjusting slot, 8 through which the screw passes which secured it to the tension plate, this slotpermitting of the adjustment of the slide to suit the varying thickness of diiferent clip-arms. In Fig. 4 I have shown this slide formed at'both ends with the upwardlyextending retaining ends,- which, as there shown extend up close to both sides of the clip arms; and with this construction the plain pin 9 is'used, which is formed without threads or head. The neck of the tension plate bearing against the joint of the coupling under the pressure of the spring will at all times prevent rattling.

It will be seen from the foregoing, that my invention is very compact in its construction, and entirely free of all complicated parts, While it is exceedingly effective in practical use. By the peculiar construction of the single spring the roller is brought squarely beneath and against the under surface of the shaft, while its wide end flanges hold it secnrely to the shaft as it works under the same 1n operation. The spring can be readily removed from the tension plate and adjusted therein to give it the proper set or tension of its coil; while the slide with its retaining end or ends securely holds the pivot-bolt of the coupling in place, and renders it impossible for the bolt to Work loose or accidentally come out.

Having thus described my invention, what I cla m, and desire to secure by Letters Patent, 1s

1. A combined shaft support. and thill cou pllng comprising the tension plate having the curved bearing neck and formed with the circular recess and circle of adjusting apertures, the spring coil entering said recess and havng the straight end adapted to be adjusted 111 any of said apertures, and having the single bent arm carrying a roller at its outer end which contacts with the under side of the shaft; substantially as set forth.

2. The combination with the tension plat'e, arranged as set forth, of the transverse slideplatc secured thereto immediately below the coupling joint and formed with the retaining end or ends extending up at right angles to the plate, for the purpose specified.

3. The combination with the tension plate, arranged as set forth, of the transverse adj ustable slide-plate secured thereto immediately below the coupling joint, having the adj usting slotthrough which the retaining screw passes, and formed with the retaining end extending up at right angles to the plate, for the purpose specified.

4. The herein -described combined shaft support and thill coupling, comprising the tension plate formed with the circular recess and circle of adjusting apertures, the retaining plate mounted on the front of the tension plate immediately below the coupling joint, the coil entering the circular recess of the tension plate and having the straight end adapted to be inserted in the circle of adjustingapertures, and having the single bent arm formed with the transverse outer end, and the roller mounted on said transverse end to contact with the under side of the shaft and formed with the retaining flanges which prevent it from slipping from the shaft; substantially as set forth.

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