Title: Improvements in or relating to Apparatus for Racking Carbonated Beverages.
Inventor: WHITE HENRY ALBERT
Filed: 1901-04-09
Granted: 1901-07-06
Abstract: 7299. White, H. A. Feb. 9, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Filling with liquids; bungs.- Relates to improvements on the invention described in Specification No. 6304, A.D. 1899, by which beer or other carbonated beverage is racked or filled into casks and the like so as to prevent foaming. The beverage is run into an overhead tank A through a pipe a. In connection with the tank, is a receiver B containing compressed carbonic acid, or air. A filling- frame D, which terminates at its lower end in a washer y which fits airtight around the bunghole, carries a sliding filling-tube d, the valve of which is automatically opened, to permit the flow of liquid, when inserted into the cask. A flexible tube f leads from the upper end of the filling-tube to the tank, as shown. In front of the filling-tube is a chamber i, which communicates with the tank through the pipes p, p<1>, and this chamber also communicates with a vent passage l, which is connected on the one hand with the tank by a flexible pipe l<1>, and opens on the other hand into the cask by a passage between the filling - tube and the bunghole bushing. The opening leading from the chamber i to the vent passage is closed by a spring valve, which, on lowering the filling-frame to the bunghole, is automatically opened for a short period to permit the flow of compressed air or gas from the tank to the cask to establish an equilibrium in the pressure in both, before the liquid is allowed to flow by gravity. This valve is opened by a rod r<1>, which abuts on the cask just before the washer y seals the bunghole, the rod being suitably connected with operating-mechanism. The vent passage l is provided with a valve q, which is opened by a handle q<1> to permit the escape of gases from the cask to the tank, as the liquid flows into the former. On moving down the filling-tube d into the bunghole, a projection d<1> in the tube trips the rule-jointed projection v<3> of a pivoted lever thus liberating the valve in the chamber i, which is then closed by its spring. When the cask is filled, the filling-tube is withdrawn, and a bung placed in a suitable receptacle in the lower end of the filling-frame is pushed into position under the filling-tube by a lever z<2>. The bung is then driven home by the filling-tube, and at the same time a crosshead F trips a rod q<3> and closes the valve q. The gases from the cask may be allowed to escape into a receptacle H, instead of into the tank A. Some of the connections may be differently made. Suitable valves and gauges are provided as shown.

The hub B is fitted with an extension E, and is mounted in ordinary ball bearings. The chain-wheel F is mounted on the extension E over a forward - driving clutch comprising rollers f<2>, Fig. 2, mounted in eccentric sockets f<1> in the chain-wheel, the extension E being grooved to prevent the rollers from slipping. A sleeve H, which is made to rotate with the chain-wheel by .lugs h<1> formed on it projecting into the sockets f<1>, is mounted on the extension E, and, on backpedalling, causes rollers m', Fig. 3, to travel along eccentric slots m formed in brake blocks k pivoted at one end l to lugs l<1> formed on a ring L, which is prevented from rotating by its arm L<1> being suitably connected with the frame. The motion of the rollers m<2> expands the blocks k against inclined surfaces K formed on the hub, and retards the cycle, the outward motion being limited by the front of the blocks engaging under the rear of the lugs l<1>. The brake surfaces are recessed at k<2> to receive a spring N, which normally presses the blocks k and rollers m' against the sleeve H. The lugs h<1> on the sleeve H prevent the rollers f from engaging when the bicycle is wheeled backwards.

Title: Improvements in Wire Drawing Machine.
Inventor: REID MARCELLUS
Filed: 1902-03-18
Granted: 1903-01-15
Abstract: 6604. Reid, M. March 18. Drawing.-A wire-drawing machine is provided with a friction clutch for driving the drawing- drum 1 and a friction band, which can be caused to engage a continuously-rotating drum 2, to thread a die on the wire. A vertical shaft 31 driven from a line shaft 39, drives the drum 2 through gearing 3, 4, 5, 6, the drum being sleeved on a central bearing 37 for the shaft 31. The die to be threaded is placed in a swivelling holder 22, and the end of the wire is held by grippers 18 carried by the friction band, which can be tightened on the drum 2 by turning a handle 15 to the position shown in dotted lines. When a sufficient length of wire has been drawn through the die, the handle strikes an adjustable stop 19, stopping the threading. The end of the wire is then transferred to a clamp 20 on the drawing-drum 1 mounted on a sleeve 13 carrying a clutch drum 12. By moving either of the handles 7 in one direction, a shaft 10 is rocked to raise a collar 27 carrying links 28 for operating levers 25 on right and left handed screws 26, which [separate friction] blocks carried by a collar 30 keyed on the shaft 31, causing the blocks to engage the clutch drum and thus gradually starting the drawing. Another wire may be threaded through a die while the first is being drawn, the holder containing several dies or drawing-apertures and the drum 2 being driven at a slower speed than the drawing-drum, to facilitate threading. The movement of the handles 7 in the opposite direction to disengage the clutch may be continued, to cause the rockshaft to operate a right and left handed screw 35, to tighten a brake strap on the clutch drum and thus bring the drawing-drum to rest. The weight of the drawing-drum is taken by a set-screw 36 resting on a hardened surface on the upper end of the shaft 31. The bearing 37 is extended upwards, to support the shaft and drum during winding. The machine described may be used separately ; or several machines may be used together, all driven by the line shaft 39.
