SPECIFICATION forming part of Letters Patent'No. 381,286. dated April 1 1888- Application filed November 10, 1887. Serial No. 254,769. (No model.)
To all whom. it may) concern.-
BeitknownthatLWILLIAM HENRY SILSBY,
' and State of California, have invented a cer tain new and useful Improvement in Paddle Belts for Propellers, of which the following is a specification.
My invention has reference in generalzto propellers in which endless belts armed with paddles run over cylindrical end'pulleys, so
as to give a long straight strokeinthe water,
and in particular to the means'employed for attaching the paddles to. the endless bands forming the body of the paddle-belt.
' The object of the improvementis to provide bands,while allowing the bands toconform to the shape of the cylindrical pulleys over which they run, so as to take a proper hold thereon.
. The invention consists'ina novel construction and'arrangement of paddle-attaching de- .vices, substantially as hereinafter described,
' part'ofthe same.
A designates the housing; B, the cylindrical belt-pulleys, of which one is the driving-pulley; and G, the pulley-adjusting or belt-tightening devices of a propeller, which is provided with an endless paddle-belt, D, constructed in accordance with my improvement.
The paddle-belt D is composed in this case of two parallel endless flat flexible bands, E, by preference of metal, which are connected at intervals by the transverse paddlesF in a well-known way. Beneath the ends of each paddle F each band E is bent to the curve of the pulleys B, orat least the driving-pulley over which it runs, and to this curved portion is riveted'or otherwise secured a rigid plate,
G, or, preferably, as here shown, are secured to opposite sides thereof twd rigid plates, 'G G, in the shape of cylindrical segments conforming to the pulleys B. 4
The plates G G serveas a base for the rigid attachment of paddles F, while causing the brace the same as they would if-wholly fiexi- I ble, so that slipping of the paddle-belt is prevented. r
In fixing theends or the paddles to therigid plates G, two uprights, '11, have their feet riv eted or otherwise secured to the. middle part of each outer plate',G, the band E, and the in-' ner plate, G, and receive closely bet-ween them the end of the corresponding paddle F.
Inclined braces I have their lower ends se-f cured to the outer ends of the outer plate, G,
preferably by bolts or rivets J passing through said plate G, the band (3, and the inner plate, G; and their upper ends attached to the opposite uprights H,'and hence to the paddle} V 'F,'preferably by a rivet 0r bolt, K, passing through said braces, posts, and paddle, asv
shown in Fig. 3. The paddlcs are-inthis way held at all times unyieldingly in a position perpendicular to the bands, so as to be most I I-claim as new, and desire to secure by Letters Patent, is-'-,
.efiective'in their action 'onthe resisting. me-

A paddle-belt consisting of a flat pliant band and rigid warped plates of a width equal to the band,'and carryingpaddles attachedat intervals to the face.of the band, the outer and innerfaces of each plate being constructed to formconcentric cylindrical segments, and the band being applied to one of said faces so as to permanently assume the curve of the same, substantially asdescribed.
