SPRING-SHACKLE.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed May 2, 1919. Serial No. 294,167.

To all whom it may concern:

Be it known that I, JOHN E. RYAN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Spring-Shackles, of which the following is a full, clear, and exact description, reference being had to the accompany ing drawings, formlng a part of this specification, in explaining its nature.

The present invention relates to an im proved shackle of that type especially adapted to form a connection between the spring and the frame of a motor veh cle.

The following are among the objects of my invention :To provide a shackle which can be easily applied to, or removed from, the vehicle; a shackle in which special provision is made for the proper lubrication of all joints; a shackle in which all binding between it and the spring or frame is entirely eliminated, thereby insuring freedom of action; and a shackle, also, in which wearin arts may be employed.

y invention can best be seen and understood by reference to the drawings, in which the shackle is shown applied to an automo: bile, of which those portions only of the frame and spring are shown with which the shackle is designed to connect, and in Which I Figure 1 is a view in side elevation.

Fig. 2 is a view partly in front elevation and partly in section.

Fig. 3 is a section on the line 3-3 of Fig. 2. i

Fig. 4 is a sectional view of the shackle.

Fig. 5 is a section on the --line 55 of Fig. 4. i

Fig. 6 is a section on the line 6-6 of Fig. 4 and Fig. 7 is a section on the line 7-7 of Fig. 4.

Referring to the drawings 1 represents the frame, 2 the sprlng and 3 the shackle connecting the spring to the frame and forming the subject-matter of my invention.

The shackle 3 comprises spaced side bars 4 and 5, respectively. These are relatively short bars parallelly arranged n spaced relationship to one another and are preferably made rectangular in cross section.

The bars 4 and 5 are rigidly connected and held in spaced relationship to one another by a bolt and nut connection with an interposed sleeve. 6 represents the shank of the bolt and 7 its head. bolt is passed through both bars at about the middle of their extension and the head of the bolt is socketed in the outer side of one of the bars to keep the bolt from turning. As shown in the drawings, the head of the bolt is contained within a socket 8 formed in the outer side of the bar 4. 9 is the nut arranged upon the end of the shank of the bolt projecting through and beyond'the bar 5, the nut tightening against the outer side of the bar 5 though in the present instance directly against a clip 10 through which the shank of the bolt extends and which is interposed between the nut and the side of the bar. The clip 10 is provided with flanges l1 turned to lap by the sides of the bar. and other flanges 12 turned to lap by the sides of the nut, the flanges thereby operating to kee 3 the nut from turning.

rranged upon that portion of the shank of the bolt running between the two bars is a sleeve 18. \Vhen the nut is tightened on the shank of the bolt the two bars are drawn into engagement with the opposite ends of the sleeve which acts to maintain the bars in proper spaced relationship to one another and also to assist in maintaining a proper parallelism between the bars.

Extending from the inner sides adjacent the ends of the respective bars and at right angles thereto are cylindrical sets of studs 15 and 16, respectively, which provide-bearings as will later be explained. The studs are preferably integral with the bars. The set of studs 15 extend in precise alinement with one another, and likewise the set of studs 16, both sets of studs being parallelly arranged with relation to eachother. The length of the studs is such that when the two bars are connected as above described a space or clearance will separate the ends of each set of studs. One of each of the respective sets of studs is made hollow with an opening .18 through it and this opening is extended through the bar to which the stud is secured whereby access may be had from outside the bars to the spaces between the ends of the respective sets of studs.

Arranged upon each of the studs of the The shank of the respective sets of studs is a sleeve 20.

as wear will come over a relatively large bear- Each of these sleeves is provided with an annular flange 21 at its outer ends. The studs provide bearings for the sleeves which are capable of turning upon the studs.

The ends of the spring and frame, which are connected by the shackle, are connected to the sleeves on the respective sets of studs, the end 22 of the spring being secured to the sleeves on the set of studs 15 and the end 23 of the frame to the sleeves on the set of the studs 16. The ends of the spring and frame may have a tight connection with the sleeves though preferably a loose fit with capability of turning thereon. When the sleeves are fixed to the ends of the spring and frame then they provide bushings therefor, the ends of the spring and frame then turning directly upon the studs.

It will be seen from the above described construction that the spaces between the ends of the sets of studs 15 and 16 are in direct communication with the joints between the studs and sleeves 20 upon them and in communication. also, with the joints between the sleeves 20 and the ends of the spring and frame in the event that the ends of the spring and frame are made so as to be capable of turning thereon. Accordingly oil introduced. into these spaces through the passages or openings 18 having direct access to the joints will keep the same properly lubricated at all times. In order to facilitate the introduction of oil there are fastened to the bar 4 oil cups 25 which are in direct communication with the respective passages 18. These cups are of the usual construction.

In order to further facilitate the feeding of oil to the various joints ll prefer to locate within the spaces between the ends of the studs wicks 26 designed to be saturated with oil at all times. Each of these wicks is retained by being socketed, one end of the wick in the end of one of the studs and the other end in the end of the adjacent stud.

i The present form of shackle is easily applied to, or removed from, the vehicle or ends of the spring and frame which it conconnects. In this connection it will be observed that the bolt or fastening joining the separate side bars of the shackle does not extend through the ends of the spring and frame, but is entirely separate therefrom. Moreover, the construction is such that one half of the shackle may be removed from the spring and frame without disconnecting the other half, which will operate in itself to form a temporary connection between the spring and frame until the other half orpart of the shackle has been appliedand the fastening between the two halves or parts of the shackle complete. The construction is also such that an equal distribution of ing surface. Moreover, substantially all the wear will be taken up by the sleeves on the studs and these, constituting as they do wearing parts, may be easily renewed as occasion re uires.

aving thus fully described my invention, I claim and desire to secure by Let,- ters Patent of the United States 1. In a shackle' of the character specified, the combination comprising spaced side bars, separate scs of studs carried by said bars providing bearings at the opposite ends thereof, the studs of each .of said respective sets of studs being spaced to leave openings between the ends thereof, one of each of said posite ends thereof, means intermediate said sets of studs connecting said bars and maintaining them in spaced relationship with one another, a wick located within the space between the ends of the studs of each of the respective sets of studs, and means whereby a lubricant may be supplied to the wicks from outside the bars.

3. In ashackle of the character specified, thecombination comprising spaced side bars, separate sets of studs with spaced ends carried by the respective bars and providing bearings between said bars at the opposite ends thereof, means interposed between said separate sets of studs connecting said bars and maintaining the same in spaced relationship with one another, and spaced sleeves arranged upon the studs of each of said respective sets of studs.

4C. In a shackle of the character specified, the combination comprising spaced side bars, separate sets of studs with spaced ends carried by the respective bars and providing bearings between said bars at the opposite ends thereof, means interposed between said ends thereof, one of each of said sets of studs and bar to which said stud is secured having an opening through it communicating through the bar and stud with the space between the studs whereby a lubricant may be supplied thereto from outside the bar, spaced sleeves carried by the respective sets of studs, each of said sleeves being provided with an annular flange, and releasable means interposed between the sets of studs con- 10 necting said bars for maintaining them and the studs carried by them in proper spaced relationship to one another.
