Description

Patented Mar. 10, 1931 UNiTED STATES4 OTTO R. BILLINGSLEY, F MASSENA, IOWA ADJUSTABLE SHACKL'E Application led March 10, 1930. Serial No. 434,760.

This invention relates to spring shackles, the primary object of the invention being to provide a shackle of the adjustable type, so

' that the body and frame of a motor vehicle may be .elevated with respect to the axle, providing a greater clearance between the wheels of the vehicle and fenders to insure against mud collecting between the wheels and fenders to retard the movements of the wheels.

Another object of the invention is to provide an adjustable shackle which may be readily and easily moved from its normal position to its adjusted position or vice versa.

A stillv further object of the invention is to provide a shackle which may be readily and easily installed in place of the shackles now in commonv use, eliminating the necessity of making changes in the usual spring construction to mount the shackles.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the y scope of what is claimed, Without departing Y from the spirit of the invention.

Referring to the drawing:

Figure 1 is an elevational view of a shackle constructed in accordance with the invention, showing the same as mounted on a spring.

Figure 2 is an elevational view of the shackle, showing the same in its extended or adjusted position.

Figure 3 is a rear elevational view of the shackle.

y Figure 4 is a perspective view of the wrench used in moving the shackle to adjust it.

Referring to the drawing in detail, the reference character 5 designates a vehicle spring, and the reference character 6 designates the rear end ofa side rail of the chassis of the vehicle. Y

The shackle comprises an upper section 7 and a lower section 8, the upper section embodying side bars 9 and lo'respectively, the 1 lower ends thereof being extended at oblique angles, as at 11. The reference character 12 designates the shackle bolt that secures the upper section to the side rail 6 of the chassis, there being provided a spacing sleeve 13 disposed between the bars 9 and 10, to hold them in spaced relation with each other.

The lower section of the shackle embodies bars 14' and 15, which are pivotally connected to the bars 9 and 10 by means of the bolt 16, there being provided a spacing sleeve 17 for holding the bars in proper spaced relation.

AAs clearly shown by Figure 3 of the drawing, the bars 14 and 15 are formed with offset portions 18 that present shoulders to be engaged by the bars 9 and 10 to restrict movement of one section with respect to the other section of the shackle. The inner ends of the bars 14 and 15 are disposed on opposite sides of, the spring with which the shackle is connected and secured to the spring by means of the shackle bolt 19, in the yusual and well known manner. f I

' Normally, the sections 7 and 8 of the shackle are held in a position as shown by Figure 1 of thedrawing, in which case the bolt 2O is positioned within aligning openings of the bars of the sections, a nut 21 being positioned on the bolt to hold the bolt against accidental displacement.

When it is desired to adjust the shackle, or increase the distance between the rear a-Xle s0 and chassis, the lever 26 such as shown by Figure 4 of the drawing, 1s positioned by placing the opening 22 over the extension 23 of the bolt 16, and the lug 24 is positioned in the opening 25 of the end portion 11 of the bar 9, B5 whereupon the bolt 20 is removed. As the lever is moved upwardly from a position as shown in dotted lines in Figure 1 of the drawing, thebars of the upper and lower sections of the shackle, are moved into parallel relation with each other, whereupon the bolt 20 is positioned to secure the sections of the shackle in their adjusted positions, as shown by Figure 2.

From the foregoing it will be obvious that 95 due to the construction shown and described, the shackle may be adjusted to increase the distance between the spring and frame of the machine, providing a greater clearance between the wheels and mud guards or fendico ers ofthe machine during muddy road conditions.

Iclaim:

l. A shackle*r Acomprising pivotally con-k l nected sections, means for securing the shackle to the spring and frame of a vehicle, e

said sections embodying space bars, formed With openings, and a bolt extended through the openings to hold the sections in their exktended or normal positions. f

v 2. A shackle comprising -piyotally connected sections, each section comprising spaced bars, means for holdingthe bars in spaced relation with eachother, said bars having openings, and a bolt extendedthrough the openingsto hold the sections in their' positionsof adjustment.A -Y n l .3. A shackle comprising van upperfsection anda lower section, each of said sections embodyingr spaced bars, the bars of the upper Y `V section havngmset. @nd portions formed with openings, means for pivotally connect- Y ing the sections atpointrs intermediate the ends of theI bars, the inner ends of the bars tending beyond'the connecting point between Y v the. sections,v and a locking bolt extended f ofthe lower section having openings, the openings of thebars of one section adapted to align with the openings of the bars of the n other section,' and a bolt extending through' the openingsto s ecurethe'sections in their positions ofadjustment. f

A shackle comprising pivotally connected sections, means foi-securing the seotion in parallel relation with each other, lto Y separate the springrand'chassis with Which theV shackle isconnected, and means for restrictingmovements of the sections With revspecttoeach other'when the shackle is in its .n
