Description
l, Il J One type of vehicle suspension system which is Ibecoming increasingly popular is the MacPherson strut sus-lpension system. The MacPherson strut is an integral coil ¦Ipring-shock absorber assembly which provides a lightweight, compact vehicle suspension system. The MacPherson strut Isuspension system is disclosed in more detail in United S-tates Patent Number 2,624,592 to E. S. MacPherson.
j One of the problems associated with the MacPherson l;strut assembly is that the shock absorber unit typically Iweaxs out before the associated coil spring. In repairing the llshock absorber unit, it is often necessary to remove the .l5 entire strut assembly from the vehicle. Once removed, it is desirous for the mechanic to support the assembly in some manner clurln~ the repair procedure.
Two companies, ~ranick Manufacturing of Fargo, North Dakota and Walker Manufacturing oE Jonesboro, ~kansas have vises which l-ave been specifically designed to support a MacPherson strut suspension assembly. soth of these vises include a support which is bolted -to a work table and c]amp assembly secured to the support. The clamp assembly includes a fixed member secured to the support and a pivoted member pivotally connected to the fixed memher. The MacPherson strut assembly is placed between these two members and a latch pivo$ally connected to the fixed member is moved into engagement with the pivoted member to pivot the clamping members toward one another to secure the strut assembly.
. . ,1 ~ ' .... . .. ..
33~3 One of the problems with the above~described type of MacPherson stru-t vise is tha-t the pivoted clamping member and the la-tch are both independently pivoted to the fixed clamping member. This type of construction typically requires the mecha-nic to utilize two hands to operate the vise. Consequentlyit is difficult for a mechanic to hold the strut assembly with one hand while operating the vise with the other. Another pro-blem associated with the above-described vise is that, since one clamping member is fixed relative to the support, the strut assembly can only be supported in a single position.
Accordingly, the invention provides an apparatus for securely supporting a generally cylindrical workpiece relative to a :Eixed support comprising, a base member, means for secur-ing -the base member -to the fixed support, clamp means mounted on the base member including a pair oE jaw members pivotally .lnterconnected, each o~ the jaw members includtng a pair of ~paced apart, generally parallel plates and means ~or maintain-ing the plates in a generally parallel spaced apart relation-ship, each of the plates having a workpiece engaging surface thereon with the engaging surfaces of one of the jaw members in facing relation to the engaging surfaces of the other of the jaw members, each o~ the workpiece engaging surfaces having a generally arcuate portion interrupted at an intermediate area ~by a notched portion!extending generally radially outwardly from the arcuate portion, and means mounted on the clamp means for effecting pivotal movement of -the jaw members relative to one another to move the workpiece engaging surfaces toward and way from one another whereby a workpiece positione~ between the surfaces may be securely supported relative to the fixed support.

A par-ticular aspect of the invention provides an appa~
ratus for securely supporting a generally cylindrical workpiece relative to a fixed suppor-t comprisins, a base member, means for securing the base member to the Eixed support, clamp means rotatably mounted on the base member i:ncluding a pair of jaw members pivotally interconnected, each of the jaw members in-cluding a pair of spaced apart, gene:rally parallel plates and means for maintaining the plates in a generally parallel spaced apart relationship, each of the plates having a workpiece en-gaging surface thereon with the engaging surfaces of one ofthe jaw members in faci.ng relation to the engaying surfaces of the other of the jaw members, each of the workpiece engaging sur~aces having a generally arcuate portion interrup-ted at an :intermediate area by a notched portion ex-tending generally ra-lS dially outwardly from -the arcuate po:rtion, means for releas-ably secu:ring the rotatable clamp means relative to the base member to m:Llitate agclins-t any :relative rotative movement there-between, and means ~ounted on the clamp means for effecting pivotal movement of the jaw members relative to one another to move.the workpiece engaging surfaces toward and away from one another whereby a workpiece positioned between the surfaces may be securely supported relative to the fixed support.
Thus, the present invention relates to an apparatus for securely supporting a workpiece relative to a fixed support.
Although the app~ratus is specially suitable for supporting a MacPherson strut suspension assembly, it is also suitable for suppor~ing other workpieces such as a rack tube of a rack and pinion steering assembly, for example. As indicated, the apparatus includes a base member which is secured relative to a fixed support. A clamp means is preferably rotatably mounted -2a-w:ith respect to the base member. Means are provided for re-leasably securing the rotatable clamp means rela-tive to the base member at predetermined intervals to militate against any relative rotative movement therebetween. The clamp means in-cludes a pair of jaw members one member of which, except for -the relative rotative movement be-tween the clamp means and the base member, is fixed relative to the base member. The second jaw member is pivotally interconnected to the first jaw member.
Both jaw members have a wor~piece engaging surface formed there-on with the engaging surfaces arranged in a facing relationto one another.

The apparatus further includes means mounted on the second jaw member and cooperating with the fixed jaw member for pivoting the ~aws relative -to one ano-ther to move the ¦workpiece engaging surfaces toward one another whereby a llworkpiece positioned between the surfaces will be securely Isupported.
¦~ Such a vise construction provides several advantages over the above-discussed prior art. First, because the clamp l means of the vise is rotatably mounted with respect to the fixed ¦ base member, the vise can be used in a varie~y of applications which require a workpiece to be supported in different positions. Secondly, since the means for pivoting the jaw members is located oh the pivoted jaw, -the operation of the llvise is simplified by permitting a mechanic to ope.rate the vise with one hand while positioning the workpiece with the other.

I' ~he jaw member 44 includes a cylindric~l sp~cer 98 ¦11 positioned between arm plates 48 and 50. The spacer 98 has 1~ reduced diameter end portions 100 which extend thxoug~ apertures in the plates 48 and 50 and are fixedly attached to each of ll ., . . ~
the plates to prevent rotation of the spacer 98. The spacer 98 has a quarter section cut out 102 formed therein having a ¦ recessed portion 104 adapted to receive the rounded end 89 l~ of the threaded shaft 84 ~ In operation, the clamp means 42 is first rota~ed with the support member 24 relative to the base member 12 to the desired working position. The securing pin 34 is then placed in either the aperture 26 or the aperture 28 and ~hrough ¦
I the respective aperture 30 or 32 formed in the s~pport member 24 to secure the clamp means relative to the base member. The user then grasps the yripping portion 82 of the handle 70 with one hand and, while pivoting the rounded end 8g out of engage-1¦ ment with the spacer 98, also pivots the jaw member 46 in a ¦¦ direction to move the gripping teeth 72 and 74 away from one ll another. This open position is illustrated in phantom in Figuxe 4. Next, the user grasps the workpiece 75 to be supported wi~.h his other hand and positions it between the gripping ¦ teeth 72 and 74 of the two jaw members 44 and 46, respectively.
Il While still holding the workpiece with one h~nd, the user Il pivots the jaw member 46 to move the gripping teeth toward one another while simultaneously pivoting the handle 78 about the support 80 to move the rounded end 89 into engagement with ¦l the recessed portion 104. The ha~dle 78 is then rotated Il a~out the longitudinal axis of the shaft 84 to screw the shaft ¦1 into the suppoxt 8~. As the rounded end 89 engages the recessed ¦I portion 104, the jaw member 46 is pivoted relative to the il jaw member 44 to cause the gripping teeth 72 and 74 to move ; ¦ toward one another and securely gra5p the workpiece.
I It wiIl be appreciated that once the workpiece is 3~ I secur~d, the user can rotate the workpiece to another position 33~ - ~
by removing the securing pin 34~ It will also be appreciated that the workpiece can be quickly removed from the clamp means 42 hy merely unscrewiny the handle 78 a few turns sufficiently 'Ito permit the handle to pivot from the quarter section cut out 102. It should be noted that, in addition to supporting a MacPherson strut assembly, that vise 10 can also be effectively used to support a rack tube of a rack and pinion steering lassembly (not shown).
¦ In accordance with the provisions of the patent ¦statutes, the principle and mode of operation of the invention have been explained in what is considered to represent its best embodiment. It should, however, be unclerstood that the invention may be practiced otherwise than as specifically illustrated and described without departing from its spirit ll or scope.

The user then grasps the yripping portion 82 of the handle 70 with one hand and, while pivoting the rounded end 8g out of engage-1¦ ment with the spacer 98, also pivots the jaw member 46 in a ¦¦ direction to move the gripping teeth 72 and 74 away from one ll another. This open position is illustrated in phantom in Figuxe 4. Next, the user grasps the workpiece 75 to be supported wi~.h his other hand and positions it between the gripping ¦ teeth 72 and 74 of the two jaw members 44 and 46, respectively.
Il While still holding the workpiece with one h~nd, the user Il pivots the jaw member 46 to move the gripping teeth toward one another while simultaneously pivoting the handle 78 about the support 80 to move the rounded end 89 into engagement with ¦l the recessed portion 104. The ha~dle 78 is then rotated Il a~out the longitudinal axis of the shaft 84 to screw the shaft ¦1 into the suppoxt 8~. As the rounded end 89 engages the recessed ¦I portion 104, the jaw member 46 is pivoted relative to the il jaw member 44 to cause the gripping teeth 72 and 74 to move ; ¦ toward one another and securely gra5p the workpiece.
I It wiIl be appreciated that once the workpiece is 3~ I secur~d, the user can rotate the workpiece to another position 33~ - ~
by removing the securing pin 34~ It will also be appreciated that the workpiece can be quickly removed from the clamp means 42 hy merely unscrewiny the handle 78 a few turns sufficiently 'Ito permit the handle to pivot from the quarter section cut out 102. It should be noted that, in addition to supporting a MacPherson strut assembly, that vise 10 can also be effectively used to support a rack tube of a rack and pinion steering lassembly (not shown).
¦ In accordance with the provisions of the patent ¦statutes, the principle and mode of operation of the invention have been explained in what is considered to represent its best embodiment. It should, however, be unclerstood that the invention may be practiced otherwise than as specifically illustrated and described without departing from its spirit ll or scope.
