Abstract
Abstract An air-driven machine, such as a rotary vibrator, is mountable on a structure by cooperative male and female parts and an airinflatable envelope is interposed between the parts to be inflated by the same air under pressure that drives the machine so that the mounting connection between the machine and structure is improved.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
101 words
A vibrator and mounting structure therefor in which the vibrator includes a housing providing a chamber containing a drivable movable part for creating vibrations, the housing and structure include cooperative male and female elements by means of which the housing may be mounted on and dismounted from the structure and releasable clamp means for selectively clamping the housing to and releasing the housing from the structure, characterized in that the clamp means includes an elastomer envelope means interposed between the elements and selectively fluid-pressurizible and depressurizible for respectively inflating and deflating to clamp and unclamp the housing relative to the structure.
Claim 2
Dependent Claim
101 words
A vibrator and mounting structure therefor in which the vibrator includes a housing providing a chamber containing a drivable movable part for creating vibrations, the housing and structure include cooperative male and female elements by means of which the housing may be mounted on and dismounted from the structure and releasable clamp means for selectively clamping the housing to and releasing the housing from the structure, characterized in that the clamp means includes an elastomer envelope means interposed between the elements and selectively fluid-pressurizible and depressurizible for respectively inflating and deflating to clamp and unclamp the housing relative to the structure.
Claim 3
Dependent Claim
62 words
The invention defined in claim 1, further characterized in that the housing chamber is selectively fluid-pressurizible and depressurizible to drive and stop the movable part and the chamber and envelope means are connected in common to a source of fluid under pressure whereby the envelope means is automatically inflated when the chamber is pressurized and automatically deflated when the chamber is depressurized.
Claim 4
Dependent Claim
26 words
The invention defined in claim 2, further characterized in that the housing includes a fluid inlet means leading to both the chamber and the envelope means.
Claim 5
Dependent Claim
39 words
The invention defined in claim 2, further characterized in that the fluid inlet means includes a housing portion forming an auxiliary chamber having a first fluid-conducting connection to the envelope means and a second fluid-conducting connection to the chamber.
Claim 6
Dependent Claim
52 words
The invention defined in claim 4, further characterized in that the first connection includes cooperative telescopically interfitting portions respectively on the housing and the envelope means so that in the event of attempted inflation of the Envelope means when the housing is dismounted the envelope will be forced off of the housing.
Claim 7
Dependent Claim
37 words
The invention defined in claim 5, further characterized in that one of the portions is neck-like, the other portion includes an opening into which the neck fits and an air-tight seal is provided between the two portions.
Claim 8
Dependent Claim
32 words
The invention defined in claim 1 in which the cooperative elements are connectible and disconnectible by relative movement along a defined path and the envelope means is inflatable crosswise of that path.
Claim 9
Dependent Claim
30 words
The invention defined in claim 7, in which stop means cooperates between the elements to limit said relative movement along said path in the direction of connection of said elements.
Claim 10
Dependent Claim
48 words
The invention defined in claim 7 in which the female element includes a pair of spaced tracks defining a channel, the male element is shaped to fit the channel, the elements are fashioned to provide a compartment between them, and the envelope means is positioned in said compartment.
Claim 11
Dependent Claim
35 words
The invention defined in claim 9, further characterized in that the tracks are convergent toward each other and the male element is complementarily shaped to provide a wedging action when the envelope means is inflated.
Claim 12
Dependent Claim
63 words
The invention defined in claim 1, further characterized in that the housing has a face portion disposed toward the structure when the vibrator is mounted and including a recess defined in part by the male element so that when the elements are fitted together a compartment is formed between the housing and the structure and the envelope means is disposed in said compartment.
Claim 13
Dependent Claim
47 words
The invention defined in claim 11, further characterized in that the face portion has an opening forming part of a fluid inlet means and the envelope means has an opening registering with the first-mentioned opening to provide at least part of the connection to said inlet means.
Claim 14
Dependent Claim
29 words
The invention defined in claim 1, further characterized in that the envelope means includes at least a pair of separate side-by-side envelopes arranged for simultaneous inflation and deflation thereof.
Claim 15
Dependent Claim
30 words
The invention defined in claim 13, further characterized in that one of the elements has a fluid cavity connected to both envelopes and connectible to a source of fluid pressure.
Claim 16
Dependent Claim
66 words
The invention defined in claim 13, further characterized in that one of the elements provides a pair of spaced apart tracks and the other element fits between the tracks, the envelopes are located between and protected at their sides by the tracks, and one of the elements includes a pair of skirts extending between the tracks in protective relation to the opposite ends of the envelopes.
Claim 17
Dependent Claim
65 words
The invention defined in claim 13, further characterized in that one element has a face portion facing toward and spaced from the other element, said one element has an auxiliary fluid chamber and said face portion has a pair of openings therethrough and communicating with the auxiliary chamber, and the envelopes are located between the elements and communicate respectively with the chamber via said openings.
Claim 18
Dependent Claim
52 words
The invention defined in claim 16, further characterized in that each envelope is associated with its opening by a telescopic connection so that in the event of attempted inflation of the envelopes when the elements are not connected the envelopes will be forced off of their respective connections with said face portion.
