연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A handheld spreader having a fillable container for dispensing particulate from an electrically powered blower assembly in a detachable base. The spreader includes a feed slide leading from the container to the air stream channel of the base that has a vibrating eccentric plate for guiding and improving the flow of particulate from container into the air stream. The container and base are frictionally engaged together, thereby allowing for easy assembly of spreader, including assembly after container has been filled with particulate, as well as easy reas...

1. A powered hand spreader, comprising: a base having a passageway having a blower positioned at one end and that extends to a second end in communication with an opening formed in said base;a cover positioned over said base and enclosing at least a portion of said passageway;a slide plate positioned over said cover and including a channel that extends along an axis from a first open end to a second partially closed end having a control aperture formed therein, wherein said control aperture is in fluid communication with an intermediate portion of said passageway, wherein said slide plate includes a pair of opposing slots formed therein and wherein each of said slots includes a first wide portion and a second narrow portion;a slide positioned in said channel for rotation between a first position wherein said control aperture is not covered by said slide and a second position where said slide at least partially covers said control aperture;a hook plate having a hole formed therethrough; anda container defining a cavity therein and including a chute that engages with said hole of said hook plate and that is in fluid communication with said cavity and said channel of said slide plate. 2. The spreader of claim 1, wherein said hook plate includes a pair of opposing tabs extending from said hole to engage with said pair of opposing slots. 3. The spreader of claim 2, wherein said hook plate may be selectively engaged and disengaged from said slide plate by rotation of said hook plate relative to said slide plate such that said opposing pair of tabs may be moved between an engaged position where said each of said tabs is tightly engaged with the narrow portion of each of said slots and a disengaged position wherein said each of said tabs are positioned in a respective wide portion of each of said slots such that said tabs may be separate from said slots. 4. The spreader of claim 1, wherein said passageway gradually widens from a point proximate to said blower to a second point prior to any communication between said passageway and said opening. 5. The spreader of claim 4, wherein said passageway narrows at said second point and then widens again at said opening. 6. The spreader of claim 1, wherein said slide includes a protrusion for manual rotation of said slide. 7. The spreader of claim 1, wherein said hook plate includes a peripheral edge that frictionally engages said container. 8. A powered hand spreader, comprising: a base having a passageway having a blower positioned at one end and that extends to a second end in communication with an opening formed in said base;a cover positioned over said base and enclosing at least a portion of said passageway;a slide plate positioned over said cover and including a channel that extends along an axis from a first open end to a second partially closed end having a control aperture formed therein, wherein said control aperture is in fluid communication with an intermediate portion of said passageway;a slide positioned in said channel for rotation between a first position wherein said control aperture is not covered by said slide and a second position where said slide at least partially covers said control aperture;a hook plate having a hole formed therethrough;a container defining a cavity therein and including a chute that engages with said hole of said hook plate and that is in fluid communication with said cavity and said channel of said slide plate; anda pull operatively interconnected to said blower and movable between a retracted position where said blower is deactivated and an extended position where said blower is activated to produce an air stream in said passageway. 9. The spreader of claim 8, wherein said pull includes a portion that is operatively interconnected to said opening of said cover such that said opening is covered by said portion of said pull when said pull is in said retracted position and is uncovered when said pull is in said extended position. 10. The spreader of claim 9, wherein movement of said pull from said retracted position to said extended position activated said blower before said opening is first uncovered. 11. The spreader of claim 8, further comprising a battery compartment positioned in said base. 12. The spreader of claim 11, further comprising a motor electrically interconnected to said battery compartment and operatively interconnected to said blower. 13. The spreader of claim 12, wherein said pull electrically disconnects said battery compartment from said motor when said pull is in said retracted position and electrically connects said batter compartment to said motor when said pull is in said extended position. 14. A powered hand spreader, comprising: a base having a passageway having a blower positioned at one end and that extends to a second end in communication with an opening formed in said base;a cover positioned over said base and enclosing at least a portion of said passageway;a slide plate positioned over said cover and including a channel that extends along an axis from a first open end to a second partially closed end having a control aperture formed therein, wherein said control aperture is in fluid communication with an intermediate portion of said passageway;a slide positioned in said channel for rotation between a first position wherein said control aperture is not covered by said slide and a second position where said slide at least partially covers said control aperture, wherein said slide extends along a plane that is non-perpendicular to said axis of said channel;a hook plate having a hole formed therethrough; anda container defining a cavity therein and including a chute that engages with said hole of said hook plate and that is in fluid communication with said cavity and said channel of said slide plate.
