FREE ROLLER-SLUICE.
Specification of Letters Patent.
Patented July 17, 1906..
Application filed April 13, 1906. Serial lio. 311,522.
To all whom it may concern.-
Be it known that I, FREDERICK WILFRID' SCOTT STORES, civil engineer, a subject ofthe King of Great Britain, residing at 32 Victoria street, IVestminster, inthe county of London, England, have invented certain .new and useful Improvements in Free Roller-Sluices, of which the following is a specification.
In free roller-sluices in which the roller- Aframe is suspended inthe loop or bight of a rope or chain, one end of which is secured to a lived support and the other end to the gate itself, the rollenframe travels upward at onehalf the speed of the sluice, and consequently the rollers are left behind and subjected to the rush of water past them. To minimize this difficulty and also to allow of access to the parts for cleaning or repairs where the lift of the sluice is greater than the range of lift against pressure7 I arrange so that the rollers and sluice are lifted at the same relative speed at the point at which the rollers are no longer required.
In order that my said invention may be clearly understood and readily carried into effect, it will now be described more fully with reference to the accompanying drawings, in which- Figure l is an end view of a sluice-gate embodying the features of my invention; and Fig. 2 is a similar view, part broken away, showing the position of the parts when the gate has been partly raised and at the moment when the pick-up device comes into operation.
The same letters of reference where they occur are used to denote the same or corresponding parts in both figures. i
In the drawings, A indicates the sluicegate B B, the rollers; D, the masonry, and E is the pick-up device or attachment hereinafter referred to.
The roller-frame is suspended in the usual manner in the bight of a chain or rope a, passing round a pulley a on the roller-frame, one end of said chain or rope being iixed to the gate at a5. In order to carry out my invention, I fix the other end c* of the chain or rope a7 to a rod E2 or its equivalent resting on a bracket or brackets or other support E in the masonry, and I provide the gate with a pick-up attachment E in the path of the rod 2, which attachment lifts the said rod E2, and with it the end oi the chain or rope 0.7, carrying the roller-train. From the time the rod E2 is lifted the roller-'frame and the rollers will travel upward at the same speed as the gate and will therefore be carried up clear of flood-level, or in the caseof sluices in dams or the like7 above the water-level7 so as to be readily accessible for cleaning, painting, or repairs. On lowering the sluice again the end or ends of the rod E2 lodge on the former support or supports E@ and the rollers thereupon resume their original relative motion to the sluice at the required spot.
It is obvious that the piclr-up arrangement herein described is applicable to any freeeroller-sluice system having its rollers secured in a suspended frame.
Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-
l. In a free roller-sluice having its rollers secured in a suspended trame, the pick-up device in which the ropes or chains whereby the roller-frame is suspended have one end iXed to the gate and the other end secured to a support which is .so mounted and disposed within the path of the gate as to be taken up thereby when said gate has reached a point at which the rollers are no longer required for the purpose of resisting the pressure, substantially as and for thepurpose specied.
2. In a i'ree roller-sluice having its rollers secured in a suspended frame, a pick-up device constructed, arranged and adapted to operate substantially as hereinbei'ore described and for the purpose speciiied.
In testimony whereof I have hereuntovset my hand, in presence of two subscribing witnesses, this 30th day of March, 1906.
FREDERICK WILFRII) SCOTT STOKES.

H. D. JAMESON, A. NUTTING.
