In many situations vibration dampening is desirable, asfor example motor mountlngs of different types. Rubber has been used for this purpose and commonly rubber so used has been placed-under compressionin order to secure the parts in their proper relation. While rubber under compression has .some dampenin-gl effect. depending on the amount of compression as ordinarily com ressed this m dampening eil'ect is negligible. y placing the rubber under tension its dampening effect may be very much increased and if it is given H initial tension a small amount of rubber may shear on the rubber and in the present invention the preferred form is so arranged. Here 'itc-both the gravity thrust of the motor and the torque thrust of the motor operate on the rubber in shear. .u
I have exempliiied my invention as a mounting for an automobile motor and Vhave "z5 illustrated the preferred formY ofy carrying out my invention. Features and details of the invention will' appear from the specification and claims. v
The invention is illustrated in the accom- :m panying drawings as follows Fig. 1 shows a sectional view of the mounting on the line 1 1 in Fig. 2.
Fig-2 a sectional view of the mounting on 'the line 2-2 in FigQl. .'13 v Fig; 3 is an end elevation of an ordinary automobile engine with .the mountings in- 1 marks the 'channel `of the automobile frame, 2 a supporting bracket secured to the channel. and 3 an arm extending from the engine frame for supporting the engine 3a,
the motor being of the ordinary automobile type delivering its power through the shaft` crank 3b. t
An opening 4 is formed in the armB pref# erably in a vertical direction. A -steel shell 5 is pressed into this opening preferably with apessed lit. Rubber 6 is secured to the shell 5 Y L bonding during vulcanization and toa central sleeve 7 also by vulcanization.. i
the load. It is.
Serial No. 800,808.
.The sleeve 7 rests on a seat 8 in the bracket 2 and a bolt. 9l extends through the bracket and throught-.he sleeve and is provided with a nut 11l at its upper end which operates on a washer larger than the opening 4 on the upper end andi clamps the sleeve on the seat 8.
y bondingftle rubber during vulcanizationthe rubber in cooling shrinks and puts all the rubber in the mountin under initial tension. By arranging the ru ber mounting with its shells in a vertical direction all the rubber is 4equally engaged in carrying the load and the load is suspended through the rubber medium, the 1rubber being equally stressed in every radial. direction, The vertical arrangement is, therefore, preferable. In any case the rubber should be so proportioned to the load that all the rubber remains under tension under the action of the load'.
Thus the load, or engine is free to move in any direction in response to vibrations butA is restrained within close limits.
Further the rubber with the axis of the joint arranged in a vertical direction, as
illustrated is subjected to shear and this-4 manner of taking the thrust is also-very sensitive to periodic vibrations, and in a ,very efficient manner insulates the member which is provided with periodic vibration producing means, suchas the engine, from theother member which is connected with such vibrat ing member.
It will be understood that lsuch vibrating members have a very definite period and the idea is to-have the mounting out of step with the period of the vibrating member. The period of vibration of a mounting arranged as here illustrated is such that it may be readily arranged to accomplish this purpose in a comparatively small space.
What I claim as new is l. In a' vibration dampening mounting, the combination of a supporting and a supported member, one of said members being provided with periodic vibration producing means and the other of said members being insulated therefrom at the mounting, said members having a normally fixed relation eX- cept for said vibrations, said members having walls with extended opposing surfaces in substantial alinement with the maor thrust under. vibration between the mem rs; and
` a mounting of resilient rubber in tension resisting engagement with Vsaid opposing sur- `faces and resisting the major thrust through shearingvaction on the rubber between its surfaces and the respective opposing surfaces of the said members, the rubber being directly inte d between the engaging surfaces.
