It has been common practice to use various constructions and materials to take up. dampen or absorb shocks, jolts and vibrations'in' many types 0! machines and vehicles. springs, rubber,

.air cushions and liquid columnsare among the means used in various arrangements and dispositions. The particular machine or equipment in which they are used is an important factor in de termining which material shall be chosen and how it shall be arranged orvdisposed.

' In order to more clearly disclose the construction, arrangement and disposition of the invention reierence should behad to the accompanying drawing forming part 0! the present application. r

Throughout the several figures oi the drawing like rererence characters de i n te the same parts in the several views.

In the drawing-- Pig. 1 is a side elevation, assembled;'

I'ig. 2 is a side elevation partly broken away to show details; and

Fi 3 is an end view of Fig. 1.

Referring to the drawing in detail, 1 indicates the cradle of usual form, adapted to receive and support a dynamotor or other machine subject to considerable vibration. This cradle is proiactured and used by or for theGovernment ior let tothe interior of the dynamotor. Guide I is constructedand disposed to cooperate with flange I through an interposedflshock and vibradon' dampening member. To that end, it has an out-- wardLvrolled curved flange I extending'about its e This time is approximately plementary to flange "I. *In assembled'positiomas-ln'l'ig. 2;thguide land flanges 1 and I IJG'IO spaced that the gynth'etic'rubb'er' or rubber snub- ,bing ring II, seated on I, will contact flange I at about the point. where I merges into cover I.

The decreasing diameter of l, pinches iI between I and 1 in any upward movement of the dynamotor and cradle relative to base I and'c'over I.

By the. arrangement hereabove set forth the blocks I provide adequate compression shock absorbing elements in movements of the cradle I toward the plates I while the ring il provides an adequate compression shock absorbing element in movements oi the connection I-I toward the flange l of base cover I. Ineflect, there is a com- Med withfootings 2 at opposite ends and opposecured to and extending upwardly from the cover I of the base I. In the instance shown, the base is a case or box containing the various conductors and binding posts. The top of this case is provided with an opening I about which extends an upwardly and inwardly extending or irusto-conical flange I through which the wiring passes from the base I to the dynamotor. A tubular guide I carried by the under side of the v plete cushion between the dynamotor and its base or support, capable or completely absorbing all shocks and vibrations between them.

These same elements I and iI also provide complete electrical insulation between the parts.

The material preferred for the compression members I and member II is synthetic rubber. By a series of severe tests, it has been satisfactorily proven that in assembly such as here disclosed, synthetic rubber is eflicient and .will give the desired results whereas various other cushioning media are not so eilicient or satisfactory.- It is thought that the construction, operation and use of the invention will be clear from preceding detailed description.

Havlngthus disclosed my invention, what I claim and desire to protect by Letters Patent is:

1. An anti-vibration mounting of the character described comprising a base provided with an opening surrounded by a'iiange, a cradle adapted to receive and support a machine provided with a centrally disposed downwardly directed tubular member adapted to be extended through said base opening and provided with a flange complementary to said base opening flange. compression anti-vibration members interposed between said cradle and said base and an antivibration member interposed between said flanges. 2. An anti-vibration mounting of the character described comprising a base provided with an opening surrounded by a flange, a cradle adapted to receive and support a machine and 'an anti-vibration member interposed between said flanges and positioned to be wedged between said flanges by relative approaching movement of said flanges.

3. In combination in an anti-vibration mounting of the character described, a base member provided with an opening thcrethrough surrounded by an inwardly and upwardly directed flange, a cradle disposed on said base and provided with a downwardly extending tubular member adapted to be passed through said opening and provided with a flange complementary to the flange about said opening, and an anti-vibration member confined between said flanges.

4. In combination in an anti-vibration mounting of the character described, a base member provided with an opening therethrough surrounded by an inwardly and upwardly curved flange, a cradle disposed on said base and prosided with a downwardly extending tubular member adapted to be passed through said opening and provided with a. downwardly and outwardiy curved flange approximately complementary to the aforesaid flange, and an anti-vibration member of greater diameter than the opening through said bas and conflned between said flanges.

5. An anti-vibration mounting of the character described comprising a base provided with an opening therethrough surrounded by an upwardly and inwardly directed flange, a support provided with a tubular member extending through said opening and provided with a downwardly and outwardly directed flange substantially complementary to and spaced from the flrst mentioned flange and an anti-vibration member interposed between said flanges and positioned to be wedged between said flanges by relative appreaching movement or said flanges.

6. An anti-vibration mounting of the character described comprising a base provided with an opening therethrough surrounded by an upwardly and inwardly directed flange, a support provided with a tubular member extending through said opening and provided with a downwardly and outwardly directed flange substantially complementary to and spaced from the flrst mentioned flange and a rubber ring interposed between said flanges and positioned to be wedged between said flanges by relative approaching movement of said flames.
