atto cmg! Patented June 3, 1930 PATENT OFFICE UNITED STATES GEORGE E. DAUBNER, OF PONTIAC, MICHIGAN, ASSIGNOR TO YELLOW TRUCK & COACH MANUFACTURING COMPANY, OF PONTIAC, ,MICHIGAN, A CORPORATION OF MAINE ENGINE surron'r Application filed February 1, 1928. Serial No. 251,186.

This invention relates to motor vehicles and more particularly to engine mountings and the like. i v

While not limited in its use, the invention is particularly adapted for use with taxicabs and other commercial automobiles, trucks and busses which are run exceptionally hard and by drivers Whoare at times inclined to be somewhat careless and frequently figure in collisions in the heavytrafficin which they are called upon to operate.

In the past, the general practice has been to rigidly mount an engine in the chassis frame, and the experience has been that a tion, particularly that which involves relative longitudinal movement with the side rails,

imposes such terrific strains on the engine and its mounting as to cause damage and breakage, necessitating costly repairs as wellas tying up the use of the vehicle during the time repairs are being made. The part that usually br'eaks is the bell housing or casing for the flywheel and clutch, of which the engine supporting legs'are an integral part, and the repair of the damage necessitates complete removal of the engine from the chassis, and the substitution of a new housing, which at times may mean a delay of several weeks be fore a new housing can be secured from a source of supply which may be situated at a distantly located point.

It is one of the objects of the present invention to provide an improved arrangement for mounting an engine which normally will firmly hold the engine in a definite location in the chassis frame but which,in the event of frame distortion, such as I has heretofore caused breakage of the bell housing, will permit a relative movement of the engine in the mounting to compensate for the distortion whereby the engine is relieved of the damaging strains.

A preferred, but not necessarily the only embodiment of the inventiomis illustrated in a transverse sectional view of a chassis rame j with an engine mounting therein in accordance with the invention.

Fig. 2 is a view looking in the direction of the arrows on line 2-2 of Fig. 1.

severe impact tending to cause frame distorthe accompanying drawing wherein Fig. 1 is I Fig. 3 is a section on line 33 of Fig. 1, and Fig. 4 is a plan view of one of the engine supporting brackets.

Referring to thedrawing, the numerals 1 -1 indicate a pair of channel shaped, longitudinally extending side sills or members of a chassis frame, in which is to be supported the engine 2 shown in outline. At the rear of the engine, the bell housing or casing is prov ded with a pair of integral laterally extending arms or legs 3-3, each of which is ,provided with a head 4 havin a peripheral groove for the reception of a ody or pad 5 of insulating or cushioning material, such as rubber or other similar elastic composition, 05 held in place by a pair of encircling, separable retainer members 67 detachably secured to each other by bolts 8. The lowermost retainer member 7 rests upon a supporting bracket carried by the longitudinal frame member 1. This bracket consists of a pair of plate-likemember's 9 and 10, the member 10 being secured by bolts or rivets 11 to the lower flange of the channeled frame member 1 and the member 9 being secured by rivets or bolts 76 12 to the vertical web of the frame member, the two plates each having overlapping end portions preferably welded or otherwise unitedwith each other and provided with aligned openings through which a long fastening pin or bolt 13 extends upwardly into threaded engagement with the lower retainer member 7 Between the head of the bolt 13 and the underside of the bracket are a pair of op ositely disposed cups 14-.-14= forming seats or hell- =cally coiled spring 15 which serves to yieldingly maintain the engine arm on the bracket. Bracing strap 16 is secured at one end by bolt 17 to the upper retainer member 6 and at its opposite end by bolt 18 to an angle iron member 19, welded, riveted, or otherwise fastened to the upper end of the bracket plate 9.

One of the mounting brackets differs from the other, in that the openingfor thelong bolt 13 in one instance is circular and of substantially the same diameter as the bolt, while in the other the opening comprises an elongated slot in which the bolt may slide in the event of frame distortion, such slotted bracket being located at the right in Fig. 1. 100

Referring particularly to Figs. 3 and 4, showing the parts in greater detail, the reference character 20 indicates the elongated slot in the bracket members 9 and 10. In order to position the engine arm in definite relation on the bracket, there is provided a thin sheet metal plate 21 over the slot and between the bracket and retainer member 7 secured to the bracket by one or more bolts 22, and having a circular opening through associated parts fromdamagingstrains.

a damaged plate by a new plate.

'The destruction of the plate is, of course,

a matter of small importance and obviously of less seriousness than breakage of the bell housing, since the replacement of a new plate may be readily made at little or no cost and in a comparatively short time. Furthermore, the destruction of the plate does not disable the vehieleas would a broken bell housing for even though the locating plate may be destroyed, the engine arm will still be supported on the bracket and held thereon by the bolt 13 so that the vehicle maybe run without any harmful effects on the driving connections, until a convenient opportunity presents itself for the replacementiof 0 make the replacement it is not necessary to remove the engine fro-1n the chassis frame but the mere detachment of the two bolts 13 and 17 will permit the side of the engine to be jacked up or lifted off the supporting bracketa slight distance sutficient to allow the damaged plate to be slid from between, the part 7 vand bracket plate 9 after removal of the fastening bolt 22 and anew plate can then be inserted. After the new plate is secured by the bolt 22, the engine arm is dropped back on the supporting bracket and fastened by the bolts 13 and 17. Repair of the damage is thus a matter of a few minutes time and trifling cost. A supply of plates can bekept on hand or they may be readily made up on short notice from scraps at any community tin shop, garage or similar place having facilities for cutting and punching holes in sheet metal.

As an alternative construction, the plate may be made of heavier stock and the bolt 22 weakened so as to be sheared in two upon strain, which will permit the bolt 13 to slide in the slot as before described.

The bracing strap 16 associated with the slotted bracket is provided with a slotted opening 23.,on which-the bolt 17 mayslide when the engine arm is moved on the bracket, the bracing plate being swung about the bolt 18 asindicated by the dotted lines in Fig. 2. H
