The knife blade or scraper portion and the pick are integrally formed in a one-piece member which is removably mounted on a body member by having the pick and a base portion of the scraper member inserted in a passage of the body member which is provided on an opposite end with a cup member which forms a tamping surface. The tool further includes a pair of cap portions for completely enclosing the knife blade or scraper portion and the cup to prevent harm to a person carrying the tool and to prevent soiling of the person''s clothes.",
  "claims": [
    "1. A pipe tool comprising: a one-piece member having a scraper portion having a base portion provided on one end thereof and an integral elontated pick extending from the base portion; a body member having a length substantially equal to the length of the elongated pick having a first end portion with a first end surface, a second end portion having means forming a tamping surface, and a passage extending in the body member from the first end surface toward the second end surface; a first removable hollow cap member telescopically received on the first end portion; and a second removable hollow cap member telescopically received on the second end portion of the body member to cover the tamping surface, said one-piece member being removably mounted in the body member with the scraper portion extending from said first end surface and the pick and base portion received in the passage so that the first removable hollow cap member covers the scraper portion and the boDy member forms a grip while using the scraper portion and so that the onepiece member may be removed from the body portion to provide a pick for use in cleaning a pipe bowl and stem.",
    "2. A pipe tool according to claim 1, wherein the first cap member is provided with a clip means for attaching the tool in a pocket so that any ashes on the tamping surface fall into the second hollow cap member.",
    "3. A pipe tool according to claim 1, wherein said means forming a tamping surface is a base of a cup member received on the second end portion to cover the second end surface.",
    "4. A pipe tool according to claim 3, wherein the base of the cup member is spaced from the second end surface of the body member.",
    "5. A pipe tool according to claim 3, wherein the cup member has a cylindrical portion, and wherein the second end portion has a cylindrical portion and a remaining portion, said cylindrical portion having a cross section smaller than the cross section of the remaining portion to form a shoulder therebetween, said cylinder portion being adjacent to said second end surface and receiving the cup member so that the interior of the second hollow cap member is spaced from the surface of the cup member.",
    "6. A pipe tool according to claim 5, wherein the first end portion and the remaining portion of the second end portion each have a cross-sectional configuration of a four sided figure.",
    "7. A pipe tool according to claim 1, wherein the second removable hollow cap member has an interior surface provided with means to prevent placement of the second cap member on the first end portion of the body member so that the second cap member is prevented from being inserted on the first end portion of the body member.",
    "8. A pipe tool according to claim 1, wherein the first end portion and the second end portion of the body member along with their respective cap members are provided with coacting projections and recesses so that the cap members are held onto the body member with a snap locking action.",
    "9. A pipe tool according to claim 1, wherein the passage adjacent the first end surface has a cross section corresponding to the cross section of the base portion of the scraper portion and a cross section spaced from said first end surface corresponding to the cross section of the pick so that the pick and base portions are snuggly engaged in the passage and the one-piece member is rigidly supported by the body member when the pick and base members are inserted in the passage.",
    "10. A pipe tool according to claim 9, wherein said base portion has a substantially rectangular cross section converging to the cross section of the pick."
