Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
201 words
In combination, a mounting device and an elongated cylindrical housing having an axially movable actuator therein, said housing having an integrally connected ring member of larger diameter thereabout intermediate its ends, a peripheral portion of said ring member being radially enlarged and having side walls which extend from the housing in a direction to provide outwardly open recesses, the mounting device comprising an elongated plate member for sealing the enlarged portion and provided adjacent the rear end thereof with a transversely extending, upwardly projecting stop member for abutting The rearwardly facing surface of the enlarged portion of the ring member, a pair of laterally spaced retaining devices on the plate member forwardly of the stop member for extending into the recesses in the side walls of the enlarged portion, a pair of walls projecting upwardly from the plate member which are laterally spaced from each other less than the diameter of the housing and of a height to engage the surface thereof on opposite sides of its axis for supporting it, and means on said plate member for removably supporting a transversely extending element bearing against the forward end of the housing for retaining the enlarged portion against the stop member.
Claim 2
Dependent Claim
201 words
In combination, a mounting device and an elongated cylindrical housing having an axially movable actuator therein, said housing having an integrally connected ring member of larger diameter thereabout intermediate its ends, a peripheral portion of said ring member being radially enlarged and having side walls which extend from the housing in a direction to provide outwardly open recesses, the mounting device comprising an elongated plate member for sealing the enlarged portion and provided adjacent the rear end thereof with a transversely extending, upwardly projecting stop member for abutting The rearwardly facing surface of the enlarged portion of the ring member, a pair of laterally spaced retaining devices on the plate member forwardly of the stop member for extending into the recesses in the side walls of the enlarged portion, a pair of walls projecting upwardly from the plate member which are laterally spaced from each other less than the diameter of the housing and of a height to engage the surface thereof on opposite sides of its axis for supporting it, and means on said plate member for removably supporting a transversely extending element bearing against the forward end of the housing for retaining the enlarged portion against the stop member.
Claim 3
Dependent Claim
47 words
A mounting device according to claim 1 wherein the actuator housing is comprised of front and rear sections provided with a pair of interlocking members integrally connected to the respective ends of the sections, said ring member comprising the outer periphery of one of the interlocking members.
Claim 4
Dependent Claim
30 words
A mounting device according to claim 2 wherein the pair of interlocking members constitute respective male and female devices, said ring member being the outer periphery of the female device.
Claim 5
Dependent Claim
76 words
A mounting device according to claim 3 wherein the male device comprises a plurality of angularly spaced teeth extending radially from the open end of the other section, the female device includes a plurality of angularly spaced teeth extending radially inward from the ring member and spaced outwardly from the end of the one section, the spacing between the teeth of the female device being such as to pass the teeth of the male device therethrough.
Claim 6
Dependent Claim
32 words
A mounting device according to claim 1 wherein the actuator within the housing is provided with an operator movable outwardly of the forward end of the housing when the actuator is energized.
