Abstract
Abstract A bobbin for manually dispensing thread from a spool rotatably held within an elongated housing. Thread is guided from the spool, through a spool support and out through a thread dispensing tip. Tension is imparted to the thread as it is dispensed through the tip by a compression spring which exerts a constant axial force against the spool. Compression of the spring and tension of the thread is adjustable by turning the tip about its axis with respect to the spool support.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
260 words
A bobbin for manually dispensing thread comprising: an elongated hollow housing having a central cavity formed along a longitudinal axis; an elongated thread dispensing tip protruding outwardly from one longitudinal end of the hollow housing having an open passage extending through its length; a cylindrical spool of thread having a central longitudinal bore; a tubular spool support member including a longitudinal tubular section aligned coaxially along the longitudinal axis; and mounting the spool for rotation about the longitudinal axis; a first open end of the spool support member in open communication with the passage, said first open end of the tubular spool support member being releasably engaged with the tip within the passage and extending therefrom through an aperture, formed through the one longitudinal end of the housing, coaxially into the cavity; a remaining end of the spool support member being open to receive thread from the spool and to direct it through the length of the tubular spool support member to the passage within the tip; frictional drag means operatively connected between the housing, the spool support, and the spool, said frictional drag means being arranged along the longitudinal section of the spool support member and yieldably engaging opposite ends of the spool, urging the first end of the spool support longitudinally inward toward the cavity and for imparting a frictional drag to the spool; and an abutment formed on the thread dispensing tip engageable with a complementary surface on the housing to limit inward movement relative to the cavity of the tip and spool support member engaged therewith.
Claim 2
Dependent Claim
260 words
A bobbin for manually dispensing thread comprising: an elongated hollow housing having a central cavity formed along a longitudinal axis; an elongated thread dispensing tip protruding outwardly from one longitudinal end of the hollow housing having an open passage extending through its length; a cylindrical spool of thread having a central longitudinal bore; a tubular spool support member including a longitudinal tubular section aligned coaxially along the longitudinal axis; and mounting the spool for rotation about the longitudinal axis; a first open end of the spool support member in open communication with the passage, said first open end of the tubular spool support member being releasably engaged with the tip within the passage and extending therefrom through an aperture, formed through the one longitudinal end of the housing, coaxially into the cavity; a remaining end of the spool support member being open to receive thread from the spool and to direct it through the length of the tubular spool support member to the passage within the tip; frictional drag means operatively connected between the housing, the spool support, and the spool, said frictional drag means being arranged along the longitudinal section of the spool support member and yieldably engaging opposite ends of the spool, urging the first end of the spool support longitudinally inward toward the cavity and for imparting a frictional drag to the spool; and an abutment formed on the thread dispensing tip engageable with a complementary surface on the housing to limit inward movement relative to the cavity of the tip and spool support member engaged therewith.
Claim 3
Dependent Claim
38 words
The thread dispensing bobbin defined in claim 1 further comprising frictional drag adjusting means operatively connected between the thread dispensing tip and the spool support member facilitating selective longitudinal adjustment of the support member relative to the tip.
Claim 4
Dependent Claim
41 words
The thread dispensing bobbin defined in claim 2 wherein the frictional drag adjusting means comprises screw threads formed along the first end threadably engageable within a complementary threaded recess formed within the tip adjacent the abutment and aligned with the passage.
Claim 5
Dependent Claim
71 words
The thread dispensing bobbin defined in claim 3 wherein the frictional drag adjusting means further comprises a lug formed on the tip and extending from the abutment inwardly toward the cavity engageable within a complementary notch formed within the complementary surface on the Housing; and means operatively connecting the housing and the spool support member for preventing rotation of the spool support member about the longitudinal axis relative to the housing.
Claim 6
Dependent Claim
83 words
The thread dispensing bobbin defined in claim 4 wherein the last named means comprises a radially outward curved portion of the tubular spool support member leading to a second longitudinal section laterally spaced from and extending longitudinally therefrom to the remaining end of the spool support member overlapping the spool; and a complementary longitudinal slot formed within the housing for receiving the second longitudinal section to thereby prevent rotation of the spool support member about the longitudinal axis with respect to the housing.
Claim 7
Dependent Claim
77 words
The thread dispensing bobbin defined in claim 2 wherein the frictional drag means comprises abutment shoulders positioned along the longitudinal tubular section within the cavity at the ends of the spool with one shoulder being freely movable along the longitudinal tubular section and the other being held stationary relative to the housing; and a compression spring operatively connected between the movable abutment shoulder and the housing to urge the shoulders axially against the ends of the spool.
Claim 8
Dependent Claim
55 words
The thread dispensing bobbin defined in claim 6 wherein the frictional drag means further includes a radially projecting flange fixed to the longitudinal tubular section sandwiching the compression spring between it and the movable shoulder whereby the spring is compressed or relaxed against the spool in response to operation of the frictional drag adjusting means.
