mun cons'rauorron Application filed March 31, 1980. Serial No. 440,474.

This invention relates generally to motor experienced capable of resisting torsional or twisting bers of numerous shapes and designs.

chassis frame construction therefor.

. Heretofore conslderable difliculty has been 1n constructmg a chassis frame movements when regular roads. to the uneven the same is moved over ir- The foregoing is due not only distribution of weight on the chassis frame, but also to the design of the sill members which are usually channelshaped in cross-section. 'Many manufacturers in an efiort to overcome twisting of the frame, as. ointed out above, brace the frame at a plura ity of'spaced points by cross mem- While cross bracing the frame is essential for various reasons, nevertheless, it has been found in actual practice to be ineffective for'preventing'torsional movement of the sill members. Another method devisedforresistingtwisting movement of the sill members is to form the same" tubular or box-shaped. This latter method has proved satisfactory .for preventin twisting of the frame, but is extremely ob ectionable owin to the difficulty encountered in securing t e cross. braces and other members to the sills.

The present invention contemplates overcoming the above disadvantages by constructing the sill members of the manner that the same resist torsional movements and at the same time provide for conveniently securing the cross members and in view,

other parts upon the frame.

With the foregoing as well as other objects the invention resides in the peculiar construction of the sill members which wil be made "more apparent as this description proceeds,- nection with wherein:

signed as to permit the attachment of various parts thereto with facility.

As shown in Figure-2, are formed of a pair of inter-fitting substantia'lly1 channel-shaped members 13 and 14 having t other and cooperating to form a box-like construction. The cross-sectional area of the channelrsh'aped member 14 is preferably substantially less than the cross-sectional area'of the. channel-shaped member 13 .and the leg portions 15 of the former channel-shaped member are spaced inwardly a substantial dlstance from 't e corresponding leg portions 16 of the channel-shaped member 13 providing ample space 17 of the cross brace members 12 and the securing means therefor, designated by the reference character 18. The leg portions 15 1 of the channel 14' terminate in laterally projecting foot flanges 19 adapted to be secured to the base portion of the channel-shaped member .13 in any suitable manner.

In order to permit-securing members to the base portions or webs of either of the channel- shaped members 13 and 14, suitable openings 20 and21, shown in Figures 2 and 3, respectively, may be formed in. the web portions for receiving a wrench or other suitable tool. The construction is such that in the event it is desired to secure a bracket, for

the sill members 11 for receiving the end portions portion ofthe channel e base portions thereof spaced from each member 13,' a bolt or other suitable securing element, designated by the reference character 22, is extended throughanopening in the web portion of the channel 13 andengaged -by extending a suitable tool through the opening 21 in the base of the channel 14. On the other hand, if it is desired to secure a member to the web of the channel 14, the securing element is extended through a suitable opening in the latter web portion, as indicated at 23 in Figure 2, and engaged by extending the tool through the aperture formed in the web of the channel 13. Thus from the above arrangement it will be observed that the sill members 11 are not only constructed to resist torsional or twisting movements, but are also designed to permit securing various parts to the flanges and base portions of the Y A sill with facility.

The constructioh shown in Figure 4 is substantially identical to the one .hereinbefore set forth except that the inner member 24 is of a slightly different configuration; As Will be apparent from the above figure, the inner member 24 difi'ers fromv the vchannel-shaped member 14 inthat the foot-flanges 25 are With this construction it will be apparent that the securing elements 29 also serve to secure the inner member 24 to the outer member 28. The manner in which various accessories such as brackets and the like are secured to the inner and outer members 24 and 28, respectively, is preferably accomplished in the same manner as in the first described form of the invention.

In Figure 5 of the drawings I have shown a sill member 30 formed of inter-fitting channel-shaped members 31 and 32 differing from the constructions hereinbefore described in that both of the channels open inwardly. The inner channel-shaped member 32 is seecuredwithin the channel 31 with the base portion thereof spaced a substantial distance from the base portion of the channel 31 with the result that a box-like construction is obtained. As shown in the above figure, the legs 33 of the inner channel member 32 engage the correspondinglegs 34 of the outer channel member 31 and form a sup ort to which thecross braces 12 are secure as indicated at 35. In this construction the securing elements 35 for the cross brace members also function to secure the channelshaped members 31 and 32 together. As shown in Figure 6', provision is made for securing various accessories to the web-or first-named channel.

- base base portions of the channels 31 and 32. The arrangement provided is substantially the same as hereinbefore set forth and accordingly a detailed description of the same is believed unnecessary.

In each of the.modification's set forth above, the sill is formed of flanged members having portions cooperating with each other to form a-box-like construction for resisting torsional stresses and having other portions permitting the attachment of various accessories to the sill member.

While several embodiments of the invention are illustrated herein somewhat in .detail, it will be obvious that numerous modifications may be resorted to without departing from the spirit and scope of this'invention and accordingly reservation is made tomake such changes as may come within the purview of the accompanying claims.

What I claim as my invention is:

1. A chassis frame having a sill comprising a channel-shaped member having a base and flanges projecting transversely from the base, and a second similar channel-shaped member extending for .substantially the full length of the channel-shaped member aforesaid and located within the latter with the base portion thereof spaced laterally from the base portion of said first-mentioned channel and with the flanges thereof projecting toward the latter base portion and spaced inwardly from the flanges of said first-named channel.

'2. A chassis frame having a sill com rising a channel-shaped member having a ase and flanges projecting transversely from the base, and a second similar. channel-shaped member extending for substantially the full length of the member aforesaid and located within the channel of the latter with the flanges thereof extending toward the base portion of said first-mentioned channel in spaced and substantially parallel relation t the flanges of the latter channel.

3. A chassis frame having a sill comprisin a channel-shaped member having a base an flanges projecting transversely from the base, a second similar channel-shaped member extending for substantially the full length of the member aforesaid and located within the channel of the latter with the flanges thereof extending toward the base portion of said first-mentioned channel in spaced and substantially parallel relation to the flanges of the'latter channel, and foot flanges projecting laterally outwardly from the ends of the flanges on said second channel and abuttin the Inner surface of thebase portion of sai 4. A chassis frame having a sill comprisin a channel-shaped member having a base an flanges projecting transversely from the a second similar channel-shaped member located within the channel of the memeia sea ber aforesaid with. the flanges thereof extending toward the base portlon of said firstmentioned channel in spaced and substantially parallel relation to the flanges of the latter channel, foot flanges pro'ecting laterally outwardly from the ends 0 the flanges on said second channel and abutting the inner surface of the base ortion of said firstnamed channel, and anges forming a con- 0 tinuation of said foot flanges projecting in the direction of the flanges on said firstmentioned channel in contacting relation with the inner surfaces of the latter.
