Carl 6. Mir/y United States Patent RESILIENT ENGINE MOUNTING Carl G. Mirly, Cape Girardeau, Mo.
Application December 3, 1951, Serial No. 259,581
1 Claim. (Cl. 248-20) The present invention relates to new and useful improvements in mountings for stationary and portable engines and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which, in addition to supporting the engine, will absorb or dampen vibration when said engine is operating.
Another very important object of the invention is to provide a resilient engine mounting of the aforementioned character which will facilitate moving the engine from place to place when desired.
Other objects of the invention are to provide a resilient engine mounting of the character described which will be comparatively simple in construction, strong, durable, compact and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in conjunction with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a rear perspective view, showing a mounting in accordance with the present invention in use.
Figure 2 is a perspective view of the device.
Figure 3 is a perspective view of a modification.
Figure 4 is a perspective view of another embodiment of the invention.
Referring now to the drawing in detail and to Figures l and 2 thereof in particular, it will be seen that reference numeral 5 designates generally a substantially U-shaped base of rubber or other suitable material. The base 5 is strong enough to support the weight of an engine 6 mounted thereon but also possesses suflicient resiliency to dampen or absorb substantially all vibration which occurs when said engine is running.
The base 5 is of arcuate cross-section and the upper or inner longitudinal marginal portions 8 of the legs 9 thereof are provided with spaced openings 10 which accommodate bolts 11 for firmly securing said base in position beneath the engine 6.
It is thought that the manner in which the device functions will be readily apparent from a consideration 2,693,925 Patented Nov. 9, 1954 of the foregoing. Briefly, the resilient base 5 is secured in position beneath the engine 6, the bight portion 12 constituting the front of said base. The outer or lower longitudinal edges 13 of the legs 9 rest on the ground or other supporting surface, the construction and arrange ment of the device being such that the engine is yieldingly supported in elevated position.
The modification illustrated in Figure 3 of the drawing is substantially similar to the device shown in Figure 2 with the exception that it comprises a substantially1 V-shaped base 14 having rearwardly diverging egs 5.
The embodiment shown in Figure 4 of the drawing comprises a pair of separate bars or base members 16 of arcuate cross-section having longitudinally spaced openings 17 in their upper portions for the reception of bolts for securing said members beneath the engine. The outer or lower longitudinal marginal portions of the bars or members 16 have formed therewith integral, outwardly extending supporting flanges 18 which are apertured, as at 19, to accommodate anchoring bolts or screws.
It is believed that the many advantages of a resilient engine mounting constructed in accordance with the present invention will be readily understood and although preferred embodiments of the device are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted which will fall Within the scope of the invention as claimed.
Having described the invention, what is claimed as new is:
An engine mounting of the character described comprising a horizontal, resilient base substanailly U-shaped in plan for mounting beneath the engine, said base be ing of arcuate transverse section and including spaced legs integral with a bight portion, one of the longitudinal edges of the base being engageable with a supporting surface, the other longitudinal edge of said base being elevated, the elevated longitudinal marginal portions of the legs having spaced openings therein for the passage of engine securing bolts.
