To all whom it may concern: Be It known that I, SorHuaPn'rnrsnN, a sub ect of the King of Denmark, residing at 369 Seventh street, Brooklyn, New York,
"machine to another. device situatedat a distance therefrom. More'particularly my invention has reference to rope or wire gearing wherein the fpulleys around which the rope passes are c s ecialconstruction toinsure non-sli ping o the rope;
i e my invention is of the general application in the art of rope or belt gearing, it has especial advantages ,for connecting a sending or control instrument to a distant caused to repeat accurately every movement of the control instrument.
Use for such deviees is found in many types of mechanical annuneiators and in aeronautic compasses of the ty e the copending a plication of- Sperry, Serial 0;, :16721steering device March 24, 1915, according the compass is side drift of the shown in shifted to compensate for.
aeroplane by an observer seated some distance therefrom. In such devices non-slipping of the transmission wire or rope is of prime importance. It is also of great advantage to have theitransm'ission gearing of sucha type that relative "movement or translation of the twoinstruments.will not affeet it that is so that it is not necessary to keep 1: e connecting cord or. wire taut. Itis the main object'of this inventionto devise a. form of mechanical transmission which is i positive and reliable. underallcircumstances I a'whereinslippage or lost motion is abolishe" and atthe sametime freedom of movement permitted.
wa er ng to at (rating -i which what -I gnow QODSldfil'f the preferred form of my invention is illustrated, Figure 1 is a View of a portionof both thesending and receiving instruments, showing-my transmission gearawrence B.
the. rope 17, with the entrance thmeto ing. In the device shown the two instru- .ments are interchangeable.
.Fig. 2 is a sectionon line of Fig. 1.
Fig. 3 is a bottom View of one of the pulleys shown in Fig. 1'. i
Fig. 4 is .a detached View of one of the disks or laminations used in the making up of 'a pulley. Fig. 5 is a sectional View of a modification;
For the purposes of. description, let it be assumed that 1 is the controller or sending instrument and 2 the receiving or repeatin instrument. An indicator may be. provide for each instru.ment.- As shown the rope grip pulle s 3 and 4: on the instruments are provide with graduations 5 and 6 which are read in connection with indices 7. [It is obvious that the indicator may be located on some other movable portion. of the instru ment, if desired.
Preferably the rope grip pulleys 4."

scribed. Pulley 3 is-mounted on a shaft 8 extending within the casing 9 of theinstru ment 1.. A hand wheel 10*or1 equivalent means is provided'to operate the pulley. In constructing the:-v ulley, preferab 7 a plurality ofydisks o amin'ations 11, i2 and, 13 are used. 'Thee'xterior disks 11 and 12 are provided'with inwardly" extending slits 14: around their edges iorming fingers 20 whereby maximumresilienc' and flexibility are secured. Spaced a smal distance from.
their peripheries the said disks are provided with annular depressions 15, 16 which cooperate to form a restricted passage 9 for 31- tial ly or wholly closed as at 18. The fingers 20 are designed to grip the rope tightly in passageway 19 and to positively prevent its escape therefrom. At their outer edges 21 the fingers 20 are bent outwardly or beveled passage 19 may be opened toallow entrance or disengagement of the rope. J
This feature is somewhat exaggerated in the drawings, in order to illustrate it clearly. The-middlejdisk 13 is of somewhat ,to furnish means whereby the entrance 1.8 to
disks apart and become wedged therebetween. All of the disks are firmly united as by rivets 30.
Preferably a positive means in the form of a spreading device or wedge-like member is used to open entrance l8. VVedge-shaped rollers 22 are probably best suited for this purpose. These rollers are pivoted on brackets 23 secured to casing adjacent the points where the rope 17 enters and leaves the pulley, so that their wedge-like peripheries spread the fingers 20 by engaging between the outturned edges 21, and thus open en trance'18 to passage 19.
The flexible connector 17 preferably is made of Wire, although cord or rope may also be used. In the claims I have used the word rope as a generic term to include all types of flexible connectors such as wire, cable, cord, rope and round belts.
The intermediate portions of wire 17 between the two instruments 1 and 2 are incased in. flexible tubing 25, secured adjacent each end tothe instrun'ients, preferably to the bracketsilj described above. Tubing may be wire wrapped as indicated by convolutions 26, and is designed. to fit wire 17 so as to prevent buckling or kinking of the wire, but at the sametime permitting tree longitudinal movement of the wire through the tube. By this means, in combination with my novel pulleys, it is no longennecessary to keep the flexible connector taut, but the two instruments may be moved around at will. By this means I glso secure the great advantage that the two instruments need not be placed so that the connectingwire is straight, but the wire can he laid in a curve in and around other objects without affecting the accuracy of iie repeaters. I
Fig. 5 shows a modified form of friction pulley 3 in which only two disks 11 and 12 are used, this form being adapted for finer wire than tlui main form of the invention.
In accordance with the provisions of the patent statutes, I have herein described the principle of operation of my invention, together with the ap iaratusv which I now consider to represent the best enlbodiment thereof, but I desire to have it understood that the apparatus shown is onlyillustrativc and that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combination and relations described, some of these may be altered and others omitted without inte fering with the more general results outlined, and the invention extends in such use.
Having described my invention, what I claim and desire to secure by Letters Patent is:
l. A rope grip device comprising resilient jacent the point where the rope leaves or the pulley on the rope.
3. A. rope grip pulley comprising resilient members adapted to grip a rope therebe-- tween, a wedge-shaped roller mounted adjacent the point where the rope engages or leaves said members adapted to lJld said members in an open position at said point, as the pulley is rotated.
4. A rope grip pulley comprising a plurality of sheet metal disks at least one of said disks having a flared periphery pr0- vided with a plurality of slits and an annulav .,.epression, the disks being secured together so that the annular depression forms engages the pullev for releasing the grip of gripping jaws for the rope.
5. rope grip pulley comprising a pair of sheet metal disks each of said disks having a flared periphery provided with a plurality of slits and an annular depression, the disks being secured together so that the annular depressions form gripping jaws for the rope.
6 A rope grip pulley comprising a plurality of flat sheet metal disks secured face to face, at least one of said disks having a flared periphery, provided with a plurality of slits and an annular depression, the disks being secured together so that the annular depression forms gripping for the rope and a wedge for spreading said jaws at a predetermined point.
7. The combination with sending and receiving instruments, of transmitting. mechanism therebetween including a pulley on each instrument comprising resilient, gripping flanges, a. wire connecting said pulleys and spreading means for said flanges positioned adjacent points where the pulleys engage the wire.
inner disk of less diameter than said outer disks, forming a seat for the rope.
10. A rope grip pulley comprising a plu rality of disks secured together, the outer disksiming provided with :1 iiu'niity of peripheral slits and an inner dish oflialneter than said nuter disks, forming a sez t for" the rope.
5 "11. A rope grip pulley comprising :1 ph1- rality of disks, the outer disks being provided with a pl'ura lity of peripheral slits alidjvith annular depressions which 006pemte to form a socket for the rope, sandin inner disk of less diameter than-said outer 10 disks, forming a seat for the rope.-
In testimony whereof, I have signed 111 name to this specification this 8th day of September 1915.
