IMPROVED ROLLRS FOR AVVASl-llNG-MACFHNES.

Specification*forming part of Letters Patent No. 36,4%, dated September 16, 1862.'

.To all wh'om it may concern."

Be it known that I, LEWIS GUILD, of Dedham, in the county of Norfolk and State of Massachusetts, have invented certainl Improvements in Rolls for Clothes Wringing and Washing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l 'is a perspective view of a roll foraclothes-wringing machine without its covering of india-rubber. Fig. 2 isa longitudinal Section through the same. v

lfu rolls for clothes wringing and washing machines, where an iron shaft passes lengthwise through the rollto give it strengthand to forni journals on which the roll turns, theiron is liable to be rusted by the water cominginto contact with it and to stain the clothes; also, where a wooden roll is placed upon the iron shaft to be afterward covered with indiarub-v which serve to secure the wooden roll to the,

Shaft and to protect the ends of the'india-rubber covering, which is afterward appliedto the roll.

I am aware thatir'on shafts have beenwashed or coated with tin, zinc, and alloys of metals to protect them from rust; but this washingor galvaniz'ingof Athe shaft would not accomplish the end I have VYinv-iew, which is not only to protect the shaft,but also to secure the wooden roll to the shaft and provide the collars which arenecessary to protect the rubber covering of the roll.

and these placed in a copper mold of' the re- That others skilled in the art may under. stand and use my invention, I willdescrihe the manner in which I have carried it out.. .j t,

In the said drawings, A is-the ironsha-ft; the wooden roll-through whichthe passed. The wooden roll is put on?.

g s aft quired forni, and a coating, a, of zinc or other suitable metal or alloyiis castouto the` iron shaft. \Atthis same time there'iscast a collarJ C, at each end of the wooden-roll, the metal entering and filling notchesc madein the end-of the wooden roll. ,f This prevents the wooden roll from turning round on the shaft. To make the zinc or alloy adhere Aproperly to the iron shaft, the shaft is ir'stcl'eagned with weak sul' phuric acid, and is then washed with a solu tion ol' zinc dissolved in*l niuriatic acid. The copper moldy is heated' to prevent the chilling of the casting.

In some cases I intend t cast on oulyone of the collars C, and after the rubber covering has been applied to the outside of the woodenl roll. to solder o n the other collar.- 'v y The wooden roll, after being securedito the shaft A, as described, is to be covered with in-' dia-rubber orv other cloth wound around it and securedliheretd'aud on thisibass is cemented the outer covering or tube of indiarnbber. If the coating a is not suiciently smooth it may be turned down in a lathe.

What I claim as my invention, and desire to secure by Letters Palent,as an iinprovementin clothes wringing and washing machines, is-

The coating a and collars C, cast onto the' shaft A, wherehythe journals are protectedA from rust, and the wooden roll B is secured to the shaft, substantially in the mannerdescribed.
