No. 12643.—29th May, 1900.—CHARLES SUTTIE, of Onehunga, New Zealand, Tanner. Improvements in sole-leather-rolling machines.*

Claim.—A device comprising one or more springs, of a strength sufficient to raise the hanging weight of a double-roller sole-leather-rolling machine, so placed with stays and connections as to connect and exert tension between the most convenient part of the framework or fixed portion of the machine and either (a) the bushes that carry the shaft of the uppermost roller or (b) the arms supporting such bushes, so as to take up all “slack” caused by wear-and-tear in the bushes or bearings of the uppermost roller and the superstructure carrying such uppermost roller, in the manner and operating substantially as described.

Claims.—(1.) The described process of manufacturing spirits and oils from kauri refuse or kauri-gum soils as defined, consisting in retorting such kauri refuse or kauri-gum soils — firstly, at a temperature of 212° to 220° Fahr., getting rid of and discarding the distillates flowing off at such temperatures; secondly, at a temperature of 280° to 300° Fahr., collecting and saving the entire distillates flowing off at such temperatures and the intermediate temperatures from 220° Fahr.; thirdly, at a temperature of 700° to 900° Fahr., collecting and saving the entire distillates flowing at such temperatures and the intermediate temperatures from 300°, mixing the collected and saved distillates as aforesaid, and clarifying such collected and saved distillates by decanting and agitating with sand, substantially as described. (2.) In the described manufacture of spirits and oils from such kauri refuse or kauri-gum soils, retorting the same at the temperatures and in manner substantially as described. (3.) In the described manufacture of spirits and oils from such kauri refuse or kauri-gum soils, decanting the supernatant liquor of the settled distillates, and treating the same by contact with sand, substantially as described.

(3.) In a device of the character described, a circular guide, a winch-barrel rotating on a horizontal axis, a platform or base upon which said winch-barrel is supported, clutch devices carried by said platform for engaging with recesses in the guide, a horizontal gear-wheel, a driving-shaft, a pinion loosely mounted on the driving-shaft and adapted for engagement with the gear-wheel, a clutch-connection between said pinion and the shaft, and a gear-connection between the said gear-wheel and the winch-barrel, substantially as specified and illustrated. (4.) In a device of the character described, a circular guide, a platform mounted to rotate on said guide, means for securing the platform as adjusted on the guide, a vertical shaft, a capstan on the upper end of said shaft, a gear-wheel at the lower end of said shaft, a driving-shaft having a pinion-connection with said gear-wheel, a spindle, a pinion loosely mounted on said spindle and adapted for engagement with the gear-wheel, means for locking said pinion in connection with the spindle, a gipsy on the outer end of said spindle, a gear-connection between the spindle and the winch-cylinder, and a drum having gear-connection with said spindle, substantially as specified and illustrated. (5.) In a device of the character described, a winch-barrel mounted to rotate on a horizontal axis and also to turn for adjustment about a vertical axis, clutch-controlled gearing for causing the movement of the winch-barrel, and means for securing the winch as adjusted, substantially as specified and illustrated.
