Abstract
Abstract A two-way measuring and centering device is disclosed. The device includes first and second tape measures extensible in opposite directions. The tape measures are located in separate compartments of a single housing. An inscribing device projects through the housing between the first and second tape measures. The inscribing device includes an elongate shaft having a flat end adapted to be struck with a hammer or otherwise depressed and an opposite pointed end for inscribing a mark when the shaft is struck. Spring bias means are provided for maintaining the shaft in a raised position with the tip enclosed in the housing until the shaft is depressed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A two-way measuring and centering device comprising: a housing having first and second mutually aligned compartments, said housing having oppositely directed complementary openings in the respective compartments; first tape measure means located within the first compartment and having a first tape extensible through the opening in said first compartment in a first direction; second tape measure means located within the second compartment and having a second tape extensible through the opening in the second compartment in a second opposite direction independently of the first tape measure means; and scribe means projecting through the housing intermediate the first and the second tape measure means, said scribe means including an elongate shaft having a first sharply pointed end and a second opposite generally flat end so that the shaft can be depressed at the flat end to inscribe a mark with the pointed end.
Claim 2
Dependent Claim
142 words
A two-way measuring and centering device comprising: a housing having first and second mutually aligned compartments, said housing having oppositely directed complementary openings in the respective compartments; first tape measure means located within the first compartment and having a first tape extensible through the opening in said first compartment in a first direction; second tape measure means located within the second compartment and having a second tape extensible through the opening in the second compartment in a second opposite direction independently of the first tape measure means; and scribe means projecting through the housing intermediate the first and the second tape measure means, said scribe means including an elongate shaft having a first sharply pointed end and a second opposite generally flat end so that the shaft can be depressed at the flat end to inscribe a mark with the pointed end.
Claim 3
Dependent Claim
67 words
A two-way measuring and centering device as recited in claim 1 and additionally comprising bias means adapted to bias the elongate shaft toward the flat end thereof and adapted to normally maintain said shaft in a first raised position, said elongate shaft being returned to said first position by said bias means after being depressed at the flat end to inscribe a mark with the pointed end.
Claim 4
Dependent Claim
72 words
A two-way measuring and centering device as recited in claim 1 and additionally comprising a marking tip attachable to the free end of the first tape so that said first tape can be extended a selected length, said scribe means being depressable to provide a pivot point for said first tape measure means and said first tape measure means being rotatable about said pivot point to inscribe an arc of a circle.
Claim 5
Dependent Claim
192 words
A two-way measuring and centering device comprising: a housing having first and second mutually aligned compartments, said housing having oppositely directed complementary openings, one of the openings being in each of the compartments respectively; first tape measure means located in the first compartment and having a first tape extensible through the opening in the first compartment; second tape measure means located in the second compartment and having a second tape extensible through the opening in the second compartment independent of the first tape measure means; and scribe means projecting through the housing between the first and the second compartments thereof at substantially the exact center of said housing, said scribe means including an elongate shaft having a first pointed end and a second opposite generally flat end, spring bias means biasing said shaft toward the second end thereof and adapted to generally maintain said shaft in a first raised position, said shaft adapted to be depressed at the flat end to motivate said shaft in the direction of the pointed end to inscribe a mark with said pointed end, said shaft being returned to said first position by said spring bias means.
Claim 6
Dependent Claim
192 words
A two-way measuring and centering device comprising: a housing having first and second mutually aligned compartments, said housing having oppositely directed complementary openings, one of the openings being in each of the compartments respectively; first tape measure means located in the first compartment and having a first tape extensible through the opening in the first compartment; second tape measure means located in the second compartment and having a second tape extensible through the opening in the second compartment independent of the first tape measure means; and scribe means projecting through the housing between the first and the second compartments thereof at substantially the exact center of said housing, said scribe means including an elongate shaft having a first pointed end and a second opposite generally flat end, spring bias means biasing said shaft toward the second end thereof and adapted to generally maintain said shaft in a first raised position, said shaft adapted to be depressed at the flat end to motivate said shaft in the direction of the pointed end to inscribe a mark with said pointed end, said shaft being returned to said first position by said spring bias means.
Claim 7
Dependent Claim
25 words
A two-way measuring and centering device as recited in claim 4 wherein the first and second tapEs include reference numerals aligned in a common direction.
