Abstract
Abstract A recess indicator is shown having an indicator shaft which is reciprocated to record characteristics of a recess to be measured. An adapter sleeve has one end which is joined to the indicator with the indicator shaft received within the interior thereof. A housing is provided which carries a gaging element with the gaging element extending from one end thereof and has a bushing which extends from the opposite end thereof. The bushing can be releasably joined to the adapter sleeve to allow for the interchange of different gaging elements.

Claim 1
Independent Claim
321 words
A recess measuring device, comprising: a recess indicator having an indicator shaft extending therefrom, the recess indicator being actuable by reciprocal movement of the indicator shaft to record characteristics of the recess being measured; a gaging element housing having an interior bore and opposite end openings; a gaging element carried by the housing within the interior bore, the gaging element being extendible at least partly from one of the end openings; a bushing retained within the interior bore of the housing and extending from the other of the opposite end openings, the bushing having an internal bore; an adapter sleeve having an interior and opposing ends, one of the opposing ends being adapted to be joined to the indicator with the indicator shaft received within the interior thereof, the other of the opposing ends being adapted to be joined to the housing with the bushing received at least partly within the interior thereof; connector means for joining the adapter sleeve to the indicator; releasable means for releasably joining the housing to the adapter sleeve, whereby a plurality of interchangeable gaging element housings can be joined to the adapter sleeve; an indicator extension extending from the indicator shaft of the measuring device through the internal bore of the bushing and into contact with the gaging element carried by the gaging element housing, whereby movement of the gaging element moves the indicator shaft to thereby actuate the recess indicator; wherein the indicator shaft and indicator extension are slidably received within the bore of the bushing; wherein the indicator extension is attached to the indicator shaft by means of a screw coupling; and wherein the recess indicator further comprises a tubular extension surrounding a portion of the indicator shaft, the tubular extension being selectively sized to be received within the interior of the adapter sleeve with the indicator shaft extending therefrom, and wherein the connector means connect the adapter sleeve to the tubular extension.

A recess measuring device, comprising: a recess indicator having an indicator shaft extending therefrom, the recess indicator being actuable by reciprocal movement of the indicator shaft to record characteristics of the recess being measured; a gaging element housing having an interior bore and opposite end openings; a gaging element carried by the housing within the interior bore, the gaging element being extendible at least partly from one of the end openings; a bushing retained within the interior bore of the housing and extending from the other of the opposite end openings, the bushing having an internal bore; an adapter sleeve having an interior and opposing ends, one of the opposing ends being adapted to be joined to the indicator with the indicator shaft received within the interior thereof, the other of the opposing ends being adapted to be joined to the housing with the bushing received at least partly within the interior thereof; connector means for joining the adapter sleeve to the indicator; releasable means for releasably joining the housing to the adapter sleeve, whereby a plurality of interchangeable gaging element housings can be joined to the adapter sleeve; an indicator extension extending from the indicator shaft of the measuring device through the internal bore of the bushing and into contact with the gaging element carried by the gaging element housing, whereby movement of the gaging element moves the indicator shaft to thereby actuate the recess indicator; wherein the indicator shaft and indicator extension are slidably received within the bore of the bushing; wherein the indicator extension is attached to the indicator shaft by means of a screw coupling; and wherein the recess indicator further comprises a tubular extension surrounding a portion of the indicator shaft, the tubular extension being selectively sized to be received within the interior of the adapter sleeve with the indicator shaft extending therefrom, and wherein the connector means connect the adapter sleeve to the tubular extension.
Claim 3
Dependent Claim
23 words
The device of claim 1, wherein the connector means comprises at least one set screw joining the adapter sleeve to the tubular extension.
Claim 4
Dependent Claim
22 words
The device of claim 2, wherein the releasable means comprises a thumb screw for releasably joining the housing to the adapter sleeve.
