Description

Предлагаемое приспособление предназначено дл  устранени  перематывани  кинопленки после ее демонстрации.The proposed fixture is intended to eliminate the rewinding of the film after its demonstration.

На чертеже фиг. 1 изображает верхнюю кассетку; фиг. 2-нижнюю кассетку; фиг. 3 - то же, в продольном разрезе; фиг. 4-тормозный механизм.In FIG. 1 shows the upper cassette; FIG. 2-lower cassette; FIG. 3 - the same, in a longitudinal section; FIG. 4-brake mechanism.

В предлагаемом приспособлении дл  устранени  перематывани  кинопленок верхн   кассетка 13 снабжена двум  валиками 1 и 2, при чем на первый навешивают мотком кинопленку, конец которой прот гивают через направл ющий валик 2, установленный внутри мотка. Пройд  через кинопроектор, пленка через прорез 20 нижней кассетки наматываетс  на валик 9 (фиг. 3), при чем нижн   кассетка сделана разъемной на шпильках 3, 4 дл  удобного вынимани  мотка пленки. Ось 5 валика 1 (фиг. 4) n-риводитс  во вращение шкивом б, а дл  регулировани  скорости вращени  валика 1 предназначен тормозный механизм , состо щий из стержн  12, несушдего на себе ось 15 валика 2 и соёачку 17, сцепл ющуюс  с зубчатым колесом 14 на оси 5 валика 1, при чем стержень 12 поддерживаетс  кернами 10, 11 и обвит пружиной 16. КогдаIn the proposed device for eliminating the rewinding of films, the upper cassette 13 is provided with two rollers 1 and 2, and a film is hung on the first one, the end of which is drawn through a guide roller 2 installed inside the skein. Passing through the film projector, the film through the slot 20 of the lower cassette is wound onto a roller 9 (Fig. 3), and the lower cassette is made detachable on the studs 3, 4 for easy removal of the film reel. The axis 5 of the roller 1 (Fig. 4) is n-driven by the pulley b, and to control the speed of rotation of the roller 1, a brake mechanism consisting of the rod 12 is designed to dry the axis 15 of the roller 2 and the coupling 17, which is engaged with the gear wheel 14 on the axis 5 of the roller 1, wherein the rod 12 is supported by cores 10, 11 and twisted by a spring 16. When

пленки подаетс  мало, то она нат гиваетс  и давит на валик 2 и этим поворачивает стержень 12, который собачкой 17 расцепитс  с зубчатым колесом 14, и ось 5 начнет вращатьс .the film is fed a little, then it pulls up and presses on the roller 2 and this turns the rod 12, which is unhooked with the toothed wheel 14 with the pawl 17, and the axis 5 begins to rotate.

Предмет изобретени .The subject matter of the invention.

1.Приспособление дл  устранени  перематывани  кинопленок, отдичажщеес  тем, что верхн   кассетка 13 снабжена двум  валиками 1 и 2, из коих первый служит дл  поддерживани  кинопленки , надеваемой на нее мотком, а второй -дл  направлени  конца кинопленки изнутри мотка через отверстие кассетки, нижн   же кассетка сделана разъемйой на шпильках 3, 4 дл  снимани  кинопленки (фиг. 1, 2 и 3),1. A device for eliminating rewinding of films, which is separated by the fact that the upper cassette 13 is equipped with two rollers 1 and 2, of which the first serves to support the film that is put on it by the coil, and the second - to guide the end of the film from the inside of the coil through the opening of the cassette the cassette is made detachable on the heels 3, 4 for film removal (Figs. 1, 2 and 3),

2.При приспособлении, указанном п. 1, тормозный механизм дл  регулировани  скорости вращени  валика 1, состо щий нз подпружиненного стержн  12, укрепленного на кернах 10, И жестко скрепленного с осью 15 валика 2 и снабженного собачкой 17, сцепл ющейс  с зубчатым колесом 14 на валика (фиг. 4).V 2. When fitted, as indicated in Clause 1, a brake mechanism for adjusting the speed of rotation of the roller 1, consisting of a spring-loaded rod 12 fastened on cores 10, And the roller 2 rigidly attached to the axis 15 and fitted with a pawl 17, which is engaged with the gear wheel 14 on the roller (Fig. 4) .V
