The purpose of this invention is to devise an (01. 180-477‘) ‘ll having an 1X member H, and the front oblique ‘member 1-2. "In addition, an auxiliary frame "member I3, is permanently attached at its rear end-to ‘the X ‘member 1 l , as by welding and runs substantially ‘longitudinally forwardly ‘therefrom to ‘an intersection with the inwardly curving for ward portion of the side member It, to which its improved mounting means for the trunnions or cross shafton whichthe clutch and brake pedals front end is secured.

It will be noted that the central ?anges member or sill of the usual automobile frame of each bell form an adequate support for the 2,406,933 3 4 The invention claimed is: ‘cross shaft which is further anchored in position 1. In a motor vehicle construction, a frame comprising a side sill and an X member having one end secured to said sill adjacent the forward portion thereof, an auxiliary frame member hav by being welded to at least one of them. More over, the complete mounting is held together by the welds through the outer ?anges.

The principal advantage of the present con 25 ing its rear end secured to said X member and extending forwardly therefrom substantially par struction is that it provides an integrated shaft allel with the longitudinal axis of said vehicle to mounting which is readily constructed from two said sill and having its forward end secured there simple stampings and which can be readily ap to, a cross shaft mounting secured to said aux plied to the motor vehicle. The provision of an auxiliary frame member supporting the shaft 30 iliary frame member and having shaft portions extending transversely on each side thereof, an mounting, as well as the clutch actuating shaft anchorage for a clutch actuating cross shaft se cured to one side of said auxiliary frame member and the master brake cylinder, adds markedly to the value of the device. It will be noted that the steps required to fabricate the mounting are simple and that this general type of a central anchorage for the shaft simpli?es the installation of the mounting. It also will be noted that by mounting the actuated means, the clutch operat ing shaft and the brake master‘ cylinder on the same frame member on opposite sides thereof forwardly of said mounting, a brake master cyl inder secured to the other side of said auxiliary frame member on the opposite side of said aux iliary frame member forwardly of said anchorage adjacent said sill, operating pedals mounted on said extending shaft portions, and linkage opera 40 tively connecting said pedals with said clutch ac tuating shaft and said brake master cylinder. tends to equalize the forces imposed during such 3. In a motor vehicle construction, a longitu periods when such forces are at a maximum as When the clutch is disengaged and the brake is applied. The frame, proper, is not crowded up with individual mountings for the pedals, clutch shaft and brake cylinder and the amount of ma terial required for the installation is substantially less, by weight, than that used in the more usual types. At the same time it is possible to make use of stampings rather than forgings, with a con sequent economy. Further, the use of a single frame member for support renders the compo nents more accessible than when, as heretofore, they-have been mounted indiscriminately on the regular frame members or on separate cross mem bers provided for that purpose. dinal channel frame member substantially par allel to the longitudinal axis of the vehicle, an r opening in the Web of the channel and a shaft mounted centrally in said opening and at right angles thereto, said shaft being mounted in a shaft mounting secured to the channel and com prising a pair of substantially complementary bell-shaped stampings provided with circumfer entially extending ?anges disposed in face-to face relationship and spot welded together, said stampings having a central aperture formed in the base of each and inturned flanges from said i ‘:ases around said central aperture substantially normal to said circumferential ?anges, said shaft Some changes may be made in the arrange ment, construction and combination of the vari ous parts of the improved device without depart ing from the spirit of the invention, and it is the 60 intention to cover by the claims, such changes as may reasonably be included within the scope thereof. being supported by said central ?anges, internally welded to one of the central inturned ?anges and adapted to mount a rotatable member on each end.
