Description

C A E E C H This invention relates to a car bench designed mainly for straightening indentations caused by accidents in oar but may also be uaed for other repair work and checking operations to be carried out on the bodies of It is an object of the present invention to facilitate and expedite such operations by providing a car bench by way of difference from the conventional benches of this does not require the dismantling of the suspensions and driving members of the to be This object is achieved to the invention by providing a car bench which comprises a robust frame formed of a pair of longitudinal beams and a pair of adjustable transverse beams each provided with means for clamping the suspension members and mechanical members not pivotally connected to the car One of the transverse beams preferably carries a supporting plate provided with holes aligned with the axes of anchoring bolts of the front auxiliary frame of the oar to permit the use of these bolts for securing said plate to the auxiliary The other adjustable transverse serving for anchoring the rear part of the car body is conveniently provided with appropriate bolts cooperating with forks for axial connection of the articulated joints of the V An auxiliary fixture may be associated w th the frame of the car bench and comprise at least one vertical bean carrying at least one thrust member having at least two surfaces adapted to resist to oppositely directed forces and engaging the frame of the car bench to transmit the pulling and pushing forces produced by the thrust member directly to said The beam of the auxiliary fixture is advantageously formed of a robust tubular section angle iron having a transversely extending base portion engaging with its end in the channel section of one of the longitudinal beams of the frame to resist to the fulling forces exerted by said thrust the transversely extending base portion being further provided with a hook engaging the upper flange of the other longitudinal beam to resist against to pushing forces exerted by the thrust A preferred embodiment of the invention will now be described by way of example and with reference to the accompanying in which 1 is a side view of a first embodiment of the car bench according to the 2 is a top plan view 3 and are sections on an enlarged taken along the lines and in 5 is an enlarged section taken on the line of 6 is an enlarged top plan view of an auxiliary fixture associated the car bench shown in 1 and useful for straightening indentations in a body of a and 7 is an elevational sectional view taken along the line of Referring to the first embodiment shown in Figs 1 to a work bench is generally indicated by 1 and comprises a pair of longitudinal beams 2 connected by transverse beams 3 so as to form a robust frame for supporting a to be repaired or checked with respect to its centering or alignment of the wheel axles relative to the Two adjustable transverse members 4 and 5 arranged on the longitudinal beams 2 and serve to retain the front and rear portions of the body of the the members 4 and being shif table along the longitudinal beams and being adapted to be secured in various for example by means of through to conform to the various dimensions of different of The adjustable transverse members 4 and provided with means engaging the suspension members and other mechanical members of the car that are not elastically connected to the so as to permit efficient securing of the body without having to dismantle the suspension and other mechanical The members and not elastical ly connected mechanical members are intended to comprise those members which are capable of exerting a resistance to the stresses exerted on the body for its These members vary in dependence upon the various types of cars to be repaired as far as the part of the car is they are generally formed by the auxiliary frame supporting the suspension elements at the rear portion of the they are formed by the longitudinal supporting arms of the suspension if the latter is of the type having helica or by the pivotal connection if the suspension is of the type having leaf In the example the work bench is designed for holding a having a rear suspension provided with longitudinal supporting The forward transverse adjusting member 4 is provided with a supporting plate 6 provided at its ends with four holes 7 aligned with the axis of the bolts existing on the car and serving to anchor the front suspension to the auxiliary The front part of the car is secured to the plate 6 by said bolts which are for this purpose removed from their seats and then screwed into the holes of the plate 6 to secure the latter to the auxiliary The rear adjustable transverse member is provided at its end with forks 8 adapted to receive said supporting arms to which the rear axle of the car is pivotally connected by screw shafts The forks 8 with connecting formed by a pair of threaded counter bolts Each bolt 11 screws into a threaded s eat 12 provided on each aide of the fork carries a hexagonal head for applying a screw and a hollow cylindrical seat for receiving a tightening screw the screw shaft 9 of the The diameter of the hollow cylindrical seat is larger than the diameter of the circle containing the hexagon of the screw 5 to permit the free rotation of the bolt and its clamping on a bracket 16 through which the shaft 9 passes Similarly the forks 8 and associated bolts can be used so as to engage the pivot pins of the shackles of the leaf springs in cars provided with the conventional type of rear Referring now to 6 and there is shown an auxiliary fixture for the car bench shown in 1 to useful for straightening indentations in the body of a car and substantially of a vertioal beam generally indicated by and shi tably attached to beams 2 of the car The vertical beam consists of a robust tubular section angle bar having vertical portion 8 and a transverse base portion A section iron 20 is arranged at the angle between the vertical and transverse portions and serves as a foot The vertical portion 18 provided with a collar 21 which can be vertically adjusted and s ecured the desired position and carries a member 22 adapted to act upon a body 23 of the oar to be repaired vdth a or pushing stress so as to produce the desired straightening of the oar The stress exerted by the thrust member 22 is transmitted to the transverse base portion which is suitably formed to transfer the stress directly to the beams 2 of the frame of the oar bench which thus does not require any connecting means to resist the stress exerted by the thrust member For this purpose the transverse base portion of the beam is appropriately bent in such a that its end 2 can engage in the channel section of one of the longitudinal beams 2 of the frame of the oar bench to resist against the tractional forces produced by the thrust member 22 and tending to push the end 24 of the base portion 1 of the beam against the adjacent face of the longitudinal beam The transverse base portion 1 of the beam is further provided with a hook 2 on its underside for engagement with the upper flange of the other longitudinal beam 2 to resist against the pushing or compression forces exerted by the thrust member 22 and tending to separate the end from the associated longitudinal beam of the frame and to produce the shifting of the beam to the right as shown in The front face of the end 24 of the transverse base portion of the beam and the end faoe of the hook 25 faoing the adjaoent longitudinal beam 2 are conveniently arranged at a distance from each other which is slightly less than the maximum distance between the longitudinal beams 2 of the frame of the car bench to permit the insertion of the end in the channel section of its associated longitudinal beam Obviously a plurality of beams as described could be associated with the car bench to permit the simultaneous use of several thrust members 22 spaced longitudinally of the oar body 23 to be straightened and each beam may carry more than one thrust member 22 in accordance with various working insufficientOCRQuality
