MOTOR-SUPPORT.

Specification of Letters Patent.

Patented Nov. 15, 19211.

Application filed October 7,1920. Serial No. 415,326.

T 0 all whom it may concern Be it known that 1, JOHN H. MCCORMICK, a citizen of the United States, residing at Creston, in the county of Union and State of Iowa, have invented certain new and useful Improvements in Motor-Supports; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

This invention relates to an improved motor support for use in connectionwith a motor in which one or both of the usual supporting brackets have become broken, the support being so constructed that it may be put in place either before or after the brackets have become broken.

Another object of the invention is to so construct the support that it will have a close fit with the motor and also have a close engagement with the lower portion of the motor bracket and have such engagement with this bracket that it will be prevented from having sliding movement when in use.

Another object of the invention is to so construct this support that it follows closely the contour of the motor casing and hanger bracket and thus prevents danger of a hole being worn in the motor casing.

Another object of the invention is to so construct this support that it may be easily and quickly put in place and further so constructed that it will be firmly held in place and prevented from accidentally slipping loose.

Another object of the invention is to so construct this support that it may be put in place before the hanger brackets have become broken and serve as means for preventing vibration of the engine and thus prevent breaking of the hanger brackets.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a bottom plan view showing the support applied to a motor.

Fig. 2 is a transverse sectional view taken along the line 2-2 of Fig. 1.

Fig. 3 is an enlarged View showing the motor hanger brackets and the outer portion of one of the hanger bars in place.

Fig. A is a perspective view of one of the hanger bars.

This improved motor support 1s used in connection with a motor 1 which is of a con ventional construction and suspended from the chassis bars 2 by hanger brackets 3 which are also of a conventional construction and provided with usual side flanges A and center web 5. This'center web or finger 5 extends longitudinally of the bracket to a point intermediate the length of the bracket where the bracket is bent transversely so that the bracket will extend from beneath the securing flanges 6 of the motor casing to a point above the flanges for engagement with the chassis bars 2. It-will thus be seen that pockets 7 will be provided upon the sides of the finger 5 between the finger and the side flanges 1- of the bracket. It has been found that vibration of the motor will often cause these hanger brackets to break off and it is then necessary to weld anew bracket in place or provide a supporting yoke for the motor. Supports-for this purpose have been provided but it has been found that the supports now in use do not have a close fit with the motor and hanger brackets and therefore the motor is permitted to vibrate and this causes the supporting yoke to wear openings in the crank casing of the motor. The device which will now be described is however so constructed that it has a close fit with the motor and hanger brackets and is prevented from having longitudinal or transverse movement and therefore will securely hold the motor and prevent vibration. Therefore, the device will serve very efiiciently to support a motor in which the hanger bracket has broken and further may be used before the brackets have broken and will serve to prevent vibration and thus prevent breaking of the brackets.

This support is in the form of hanger bars 8 each of which is constructed as shown in Fig. 4:. The hanger bar is provided with a foot 9 at its inner end which is provided with openings 10 to receive the securing bolts 11 by means of which the two hanger bars will be securely clamped beneath the motor. This hanger bar is provided at its outer end with spaced fingers 12 having hooked end portions and thus constituting hooks which will engage the chassis bar as shown in Fig. 2 and as shown in Fig. 3 will extend longitudinally of the pocket 7 between the finger 5 and the flanges 4 of the brackets 3. At the base of the hooks, the hanger bar is bent to ofiset the hooks and permit the hanger bar to engage the lower portion of the hanger bracket beneath the flanges 6 of the motor. This further provides an abutment shoulder 13 which Will engage the brackets beneath the flanges of the motor and serve to prevent movement oi the hanger bar longitudinally in one direction. The hanger bar s again bent longitudinally at the lower end oi the bracket to bring V the hanger bar into en gagement iviththe base of the crank case and from this point to the foot 9, the hanger bar is curved longitudinally sothat it conforms to the contour oi? the crank casing. It will thus be seen that when the support is put inplace, it Will conform to the contour of the crank casing and hanger bracket and will be held against longitudinal movement by the

shoulders

13 and 14 and against transverse movement by thehooks 12 Which ht into the pocket 7. Vibration of the motor Will therefore be overconieand breakage oi the brackets prevented or very etficient supporting of the motor permitted in case the support is put in place after breaking of a V bracket.
