4 Serial No. 322,731. f
To all 'wlwfm it may concern:
Be it known that LCHRISTIAN JOHNSON, a citizen of the United States,- residing at Elgin, in the-county of Kane and `State of Illinois, have invented certain new and useful Improvements in Intermittent Grip Mechanism, of which the following is a specification.
This invention relates particularly to intermittent gri mechanism used in connection with win ing devices for spring motors for automatic piano players, and especially lo the construction and arrangement of details and parts as will hereinafter more fully appear.
lThe principal object Of'this invention is to provide a simple, economical and etiicient intermittent grip mechanism used in lconnection with a `safety clutch, as set forth in my Patent No. 825,323, application No. 203,286, of which this application is a division, thoughl it. will be understood that this intermittent grip may be used at any place where such devices are necessary.
In the accompanying drawings-Figure l is an elevation, Apartly insection, of my improved intermittent grip. Fig. 2 is a sectional view, 'taken on the line 2 of Fig. 3. Fig. 3 is a? sectional detail, taken on the line 3 o f Fig. 1. Fi 4. is ay perspective view Ot the disassociate parts of the mechanism,
showing. the relative arrangement thereof before the parts are assembled.
In the drawings I illustrate a double lever mechanism having frictional engagement with an arbor or part to be rotated, all of which permits rotation in one direction Wh-ile rotation in the other direction is prevented. To this end I provide a centrally' located wheel-or disk s rigidly secured by means of a. pin t to the arbor or part to be` rotated.
' Ratchets u are provided and rigidly secured, b means of dowel pins o, toeach face of t e centrally located disk. Two operating levers w and w are provided, each of which has a bored hub portion y-rotatably mounted in position around the peri hery of the ratchets, `as shown particular y in l Figs. 3 and 4.` These bored hub portions are so mounted as to provide a plurality of y pressed rollers ratchet spaces z between the ratchets and the bored hub portions of the operating levers, and in these ratchet spaces are movably mounted .rollers 10. lnterposed between these rollers and the shoulders of the ratchets are helically coiled springs 11, so arranged that as the operating lever mechanisms are vibrated in the direction -indicated by the arrow in Fig. l, the rolls cause a gripping action to take place between thel lever and the ratchet, so as to carrythe arbor around in One direction. It will be seen from an examination of the detail view shown in Fig. 4 that the ratchets are secure to the faces of thec'entrally located disk in the same manner. By this arrangement one of the operating levers rw can be vibrated in one direction, while the o erating lever is vibrated in the other irection, thus giving a constant step by step rotation to the key arbor a. To hold the parts of the operating levers in position-in other words, to prevent the displacement of the operating levers, rolls and springs ll from o erative positionface plates 12 are rovi ed and rigidly secured to the faces o the ratchets,
ooV
by means of headed screws 1 3.' It will be Observed that the lratchets adjacent the shouldered portions are provided with Offsets or depressions b, for the purpose of maintaining the angle between the face of the ratchet portion u and the inner face of the vring y small enou h to secure positive- Afixed-to said disk, levers having. hub portions surroundinv said ratchet wheels, spring between the said hub portions and the ratchets, and retaining plates attached to the outside faces of the ratchet-v wheels. l
