Benjamin was born in 1900 in Hook Norton, Oxfordshire, England, but moved with his parents and siblings to live in Wales somewhen after the 1901 census. I understand that he moved from Wales later in life and was involved in the initial repairs to the famous Transporter Bridge at Middlesbrough, Teeside, England. The bridge was constructed in 1911.

The Transporter Bridge spans the River Tees and is today part of the industrial heritage of the area. It's capable of carrying 600 people at a time. You drive or walk into a cradle that is suspended beneath the main span of the bridge and the cradle carries its load of cars and pedestrians across the Tees some 160ft above the river in just two and a half minutes.



The above is a picture of the famous Runcorn and Widnes transporter bridge that Benjamin will have worked on.

From the Western Mail - 28 December 1921:
BOMBS IN GARDEN.
THEFTS FROM LLANBRADACH COLLIERIES
Edward Bamford (22), John Richard Knibbs (25), journeyman; William Robert Knibbs (25)„ carpenter; and Benjamin Baden Knibbs (21), shackler, all of Llambredach, were charged at Caerphilly on Tuesday with having stolen electric batteries, &c., value £1 8s. 8d., the property of the Cardiff Collieries, Llanbradach, between November 1 and December 13. Rumford pleaded guilty and the others not guilty.
Mr. Prosserr (Messrs Kenshole and Prosser, (Aberdare) prosecuted. Mr. C. S. Goodfellow defended the Knibbees.
It was stated is evidence by Police-sergeant Phillips that defendants all lived in the same house, in Church-street, LLanbradach. Rumford was a lodger. Witness had received complaints of bombs going off in the garden, and the colliery company had been mining large quantities of blast fibre from the quarries. Witness bad heard of these explosion., and went in company with Police-sergeant Davies to Church-street on the 13th.
William Robert Knibbs and Rumford were on the doorstep. Police-sergeant Davies explained to them that they were inquiring about a gun and some powder. William Robert produced a gun and some powder, When witness was passing through the kitchen Rumford grabbed something from beneath the stairs and put it under his coat and ran out through the back way. They were unable to catch him.
In the little room beneath the stairs witness found a quantity of fuse produced. William Hobert and John Knibbs said they knew nothing about it. Witness continueded to search and found six batteries, a porus pot, a length of cable, and a chisel. He drew the attention of the Knibbess to this, and they said they knew nothing at all about it.
Witness took possession of the goods and on the 16th arrested Rumford at the colliery lamp-room. At the police-station he charged him with the offences. Rumford replied, I admit stealing six batteries and fuse, but did not steal the porus pot, the electric cable, or the chisel." He made no reply regarding the powder. Later witness arrested the brothers Knibbs and conveyed them to Caerphilly Police-station, and the four persons were jointly tried.
Witness produced a long signed statement by Bumford. In this Bumford alleged that the porus pot was brought home by Ben Knibbs and placed under the stairs. He had seen Benjamin Knibbs and Jack Knibbs bring lengths of cable home from the colliery. He had seen Jack Knibbs stripping the electric cable to make shoe laces.
Replying. to the charge John Robert Knibbs said, "I know nothing about
the batteries or the stripping of the cable." The other two said they knew nothing about it.
Mr. C. S. Goodfellow submitted that there was no evidence against John Knibbs. His instructions were that Bumford was turned out of his home and lived "rough" in the mountains. During the inclement weather, out of sympathy, Mrs. Knibbs took him in and gave him a home against the wishes of her sons. There could be no doubt that some of the articles mentioned had been brought to the house by Bumford. The boy Benjamin Knibbs admitted having been up the mountain with Bumford, but he denied having had earthing to do with the actual theft of things. His (Mr. Goodfellow's) conclusion was that Bumford was roughing it up on the mountain and having nothing to do he took the things home. Mention had been made of a gun given to him by his uncle but had always had a licence for it.
Mr. Goodfellow did not call any of the defendants and Superiatendent Williams said that there was nothing known previously against them.
The Chairman (Mr. W. Ware) pointed out that there was a good deal of theft from the collieries going on. He regarded Bumford as the worst offender. He would be fined £3 and the others £2 each.

Note: Benjamin's job was given as "shackler". A shackler worked in the coal mining industry and was responsible for coupling or uncoupling trams by means of shackles.
