JACK CHAIN Original Filed Nov. 13, 1962 INVENTORy L/ssELL K. ULM
3,183,795 JAQK CHAEN Rnsseli I. Uhn, Butler, End., assigner to Universali Tool d: Stamping Company, luc., Butler, ind., a corporation of Indiana Original application Nov. 13, 1962, Ser. No. 236,91S. Divided and this application im. 23, 196e, Ser. No.
5 Claims. (Cl. 59-91) y'This invention relates to an improved chain adapted particularly 'for use in connection with vehicle jacks and of such nature as `to be capable of quick length ladjustment to suit height requirements of .the lifting means of the jack with respect to the bumper or other vehicle part to be engaged by the chain.
The present invention constitutes a division out of applicati-on Serial No. 236,918, filed November 13, 1962.
A yfurther object of this invention is the provision of a strong, sturdy, exible Ichain comprising a plurality of `metal links which are pivotally connected together so that the curvature of the chain can be adjusted to suit length conditions.
Other objects and advantages of this invention will be app-arent during the course o-f the following detailed description.
In the accompany-ing drawing forming a part of this specification and wherein similar reference characters designate corresponding par-ts throughout the several views:
vFIGURE l is a plan view of the link type chain.
FIGURE 2 is a side elevation of the chain sho-wn in FIGURE l; the dot-and-dash line showing the manner in which the links can be adjusted when desired to be placed out of the Way to suit length conditions in connection with the appliance with which the chain is to be used.
'FIGURE 3 is a vertical cross-sectional v-iew taken through the chain substantially on the line 3 3 of FIG- URE l.
FIGURE 4 is a transverse cross-sectional view taken substantially on the line 4-4 of FIGURE l.
FIGURE 5 is a transverse crosssection view taken through one of the pintle or pivot hinges adapted to connect adjacent links; the View being taken substantially on the line 5-5 of FIGURE 2.
FIGURE 6 is a cross-sectional View taken substantially on the line 6-6 of FIGURE 2.
FIGURE 7 is a perspective View of .one of the links of the chain taken from the under side thereof.
In the drawing, the letter A may generally designate the chain. It is of a type intended to be used with a jack structure Such as Iset -forth in United States application Serial No, 236,918, tiled November 13, 1962.
The .articulated chain structure A is formed of a plurality of links 95. They are preferably termed of rigid metal and each includes relatively divergent side walls 96 shown in FIG. 6 connected by an integral bridging narrow outer 4wall 97 shown in FlG. 4. The walls 96 extend beyond the side edges of the connecting wall 97 yand at these loc-ations lthey are Iapertured at 99 to receive hinge pins litt) which connect the various links in pivoted relation, one to the other. The pins 190 have heads lll at one end and at the other end they are peened at 162 and rest against washers 163. lf desired, washers may be placed at both ends of the pins 1&9 at each outer side of the walls 96. Due to the relative slope of the walls 96, links 95 can be conveniently interfitted, as is sho'wn in FIG. 6, to provide a very compact and economically fabricated structure. The pins dit@ are uniformly spaced, and are in parallelism, so that they will accurately lit into a lift retainer such as set forth in United States application Serial No. 236,918, tiled November 13, 1962. This lift retainer has a plurality of YUnited States Patent O M Patented lune l5, i965 sockets adapted to receive a plurality of the pins 160. To that end the links form a chain channel entirely open at the bottom of the chain throughout its length with no obstructions to insertion of the lift retainer and its adjustment along .the channel throughout lthe length of the chain. Ilf desired friction pads 1&4 may be att-ached on the outer surfaces of the cross walls 97 4to prevent marring of bumpers and other vehicle parts with which the chain may come in contact during a lift-ing operation.
The .chain structure at its lower end is provided with a bumper or vehicle frame engaging hook 106 having top ears 167, apertured to pivotally receive the lowermost pin ltla of the lowermost link. The hook side walls are divergently `flared as :sh-own in FIG. 1. The end 1418 is hooked for engagement beneath -a Vehicle frame or bumper.
It will be note'd that the parts of the chain A are of rigid stamped metal with the exception of the metal hinge pins, and t-he cushioning pads 104. It will be noted that the plane of the `connecting wall 97 of each link is at an angle olf 9() degrees with respect to the planes of the side walls 96. The ends of the walls 96 extend alpprecialbly beyond the Ifore and aft edges of the cross walls 97 in order that the chain links can curve to an outof-the-way position as is shown in dot-and-dash lines in FIG. 2. It will also be noted that the bottom surface of the bridging walls 97 lie in a plane appreciably spaced from the 4hinge pins 10) to facilitate mounting of the hinge pins and link upon a lift retainer of the jack structure with ,which this chain is adapted to be used, such as set forth in application Serial No. 236,918, filed Novem-ber 13, 1962.
Various changes in the size, shape and arrangement of parts may be made to the form of invention shown, Without departing from the spirit of invention or scope of thev claims.
I 'cl-aim:
1. As an article of manufacture a vehicle lifting chain comprising a plurality of pivotally connected links each having a pair off spaced side walls and a bridging wall connected to the outer margins olf the side walls at th front part of the chain, said side walls being being apertured at each end, and pins extending through said apertures crosswise of the length of the chain and pivotally connecting the links together, said side walls of each link being rela-tively divergent from end to end to such a degree that the side wall-s of the link at the closes-t end spacing of its walls will fit into and 'between the walls of an adjacent link at i-ts widest `spacing of said side walls.
2. A jack chain as described in .claim 1 in which the bridging wall of each link is relatively narrow compared lto the length of the side walls so that the side margins of the bridging wall of each link terminate apprecia-bly short of the pins which connect adjacent links together.
3. The jack chain described in claim 11 in which the side walls below the cross walls define a channel which is entirely open at the bottom of the chain and unobstructed Ifor attachment of .a lift retainer with the exception of said cross pins onto which a lift retainer is adapted to be hooked.
4. The chain described in claim 1 in which the end link of the chain whose side walls are endwise spaced at their greatest width has a hook pivotally connected thereto.
5. As an article of manufacture a vehicle jack chain comprising a plurality of 'pivotally connected links each comprising a pair of spaced side walls and an integral bridging wall connected to the louter margins lof the side walls at lthe front of the chain, said side walls being apertured at each end at loca-tions entirely beyond the marginal edges of the cross walls, and uniformly spaced pins extending through said aperture crosswise of the length of the chain and pivotally connecting the links together, said links when in line delininga channel Vwhich is entirely open at the rear thereof opposite said cpo-ss walls with Y the exception of said pins which lie and about midway of the depth of the Ichannel throughout the, length of said channel. g A
