- Model of Alves' Patent Silt Elevator and Carrier
This is a machine, or rather a combination of two machines, for raising stuff from a punt and afterwards carrying it to almost any distance required, at any rate within reason. Messrs. Alves and Howorth are the patentees, and patents have been taken out in New Zealand, the Australian colonies, and America.
The working model exhibited is on a scale of 1½ inchs to the foot, and the carrier, as it stands, can take the stuff nearly a chain—that is, proportionately to scale.
In full-size machine the ropes will be crucible steel, flat or round, as may be required for the special work to be done.
The clips will be made of steel moulded to fit strands of ropes. (See clips screwed to top rail of model.) Each clip will be fastened by bolt and nut, and will bear a strain on each bucket of two tons without slipping.
page 55
The buckets will be made of steel-plate and capable of holding 2 cwt. of material. The lifting buckets will be fastened to the ropes with 4 clips to each to resist a strain on each bucket of 4 tons. The carrying buckets are reversible and easily adjusted.
Whenever it becomes necessary to extend the carrying ladder, a wire rope is stretched over the trestles to the distance required.
The bucket-ladder can be made of sufficient length and strength to dredge direct from bottom of docks or rivers instead of lifting the material out of punts, as shown.
By fixing the lifting-ladder in front of the machine, a canal can be cut and the material carried and deposited by one and the same operation.
There being no pins to wear as in pitch chains, and the ropes passing smoothly over the pulley-wheels, the wear and tear is reduced to a minimum, great rapidity of speed is gained, and a great saving of engine-power is effected.
