Application filed November 22, 1911. Serial No. 661,647.

To all whom it may concern Be it known that I, WILLIAM MEISCHKE- SMITH, a subject of the King of Great Britain, residing in London. England, (whose post-oflice address is The Asiatic Petroleum Company Limited, of 24 and 28 St. Mary Axe, in the city of London, England,) civil engineer. have invented a certain new and useful Improved Machine for Delivering Measured Quantities of Liquids, of which the following is a specification.

The invention relates to'machines for filling oil tins with a constant weight of oil, and applies more particularly to the arrangement by which a number of these cans or tins is placed on a square support on a turn-table, so that all the tins on one side are filled at the same time by nozzles connected to the separate compartments of a large container. It is important in practice that each tin should contain the same predetermined weight of oil irrespective of the changes of density of the liquid due to temperature or other causes. For this purpose the volume of the oil discharged from its oompartment into the respective tins must vary according to the density, capacity of each compartment must be adjusted correspondingly, and for practical eiiiciency this change of capacity should be effected simultaneously for all the compartments. Arrangements have been proposed for altering the capacity of the compartment according to the specific gravity of the difierent liquids used as shown by an index, and plans have also been proposed to alter the capacity according to the temperature, when the same liquid is always employed. ut no arrangement has hitherto been known in which the capacity of the compartments can be adjusted for liquids of different specific gravities at varying temperatures by setting an index to the corresponding graduation on a fixed scale. According to the present invention, when the density of the oil has been determined by a preliminary operation, the requisite change of capacity of each compartment is simultaneously effected by setting a hand to the graduation of a dial corresponding to this density, and should any change of temperature occur atfecting the density of the oil, the capacitv change is effected by moving a second pointer connected to a spindle carrying both pointers to a graduation on the same dial that is the effective corresponding to the temperature as shown by a thermometer immersed in the liquid. The ad ustment is rapidly made simultaneously for every compartment by simply observlng the thermometer and turning a hand wheel until the pointer connected to the hand wheel shaft by suitable gearing is opposite the actual temperature at the time, as shown on the graduated dial. According to the invention also the rotation of the shaft connected to the hand wheel adjusts slmultaneously the axial positions of the end plates of drums, one of which is fixed in every compartment, so as to vary the capac1ty of these compartments as required. Also improved means are described of releaslng the air during the process of filling the compartments with oil and of lowering the nozzles and opening the discharge stop cocks when the compartments are being emptied.

Figure 1 isia part side elevation showing one compartment in section, Fig. 2 an end elevation of a machine constructed according to the invention, Fig. 3 is a complete plan view to a reduced scale, Fig. 4 shows one of the air release valves, Fig. 5 is a sectional elevation, to enlarged scale, of one of the compartment drums with an adjustable end plate, Fig. 6 is a sectional plan of a portion of the containing vessel, showing the compartment ofFig. 5, and Fig. 7 is an end elevation ofa'part' of the compartment casmg and containing vessel.

In the figures, 1 represents the separate compartments of the containing vessel, 2 the cylindrical drum, whose capacity can be varied by the axial displacement of the end plate 3, rigidly attached by the key 6 to the shaft 4, which can be turned by the hand wheel 5, not shown in Fig. 2. The end plate 3 has a screw thread on its outer circumference engaging with a screw thread on the inner circumference of the fixed cylinder 2. Small holes at the top of this fixed end allow the space between the fixed and movable ends of the cylinders to be filled with the oil. On the exterior of drum 2, a plurality of guide members 2 having slotways 2 running parallel with the axis of the drum are fixed Figs. 57. A bolt 7, having a threaded portion screwable in a boss 1 on the side of the compartment 1. is adapted to be turned so that its terminal point may enter or be withdrawn from the I slot of one or other of the guides when brought into register with it. When the point of bolt 7 engages a slot 2 the drum is held fast, but when the point is withdrawn, the drum is free to be rotated by hand through a hand hole provided with a cover 8. When it is required to adjust the capacity of any compartment independently of the others, the associated bolt 7 is released and the cylinder 2 rotated by hand through the hand hole and again fixed by means of bolt 7. To the cover 8 a piece of hard wood is attached; by reducing, or if necessary en tirely removing, this piece, the capacity of the compartment may be considerably increased when required. By the means described the capacity of each compartment of the machine may in the ordinary construction be varied so as to deliver the same weight of oil for any specific gravity between the limits of .7 8 and .85, but this range can be varied in the construction of the machine to suit special requirements. It is obvious that other equivalent devices for displacing the movable end of the cylinder may be substituted for the screw threads shown by way of example.

The shaft 1 is connected by the reducing gear 9 to the spindle 12 which carries the two pointers 10 and 11. Both pointers move over a dial 14 provided with two scales 14', 14 the one graduated in terms of density, the other in degrees of temperature. In adjusting the capacity of each compartment, the density of the oil is determined in the ordinary way by drawing off a small quantity by a stop cock 38 provided on the reservoir 38 for this purpose; the hand wheel 5 is then turned until the pointer 10 is opposite the graduation showing this density on the density scale 11' of the dial 14. The temperature of the oil is then read off from a thermometer. preferably of the circular form with dial 38, immersed 1n the reservoir at a position where it can be readily seen by an operator at the hand wheel 5. The hand 11 which is loose on the spindle is then turned until it is opposite the graduation corresponding to the actual temperature on the scale 14 on the dial 14 and clamped in this position by the milled nut 13. The temperature scale is graduated so that the indications represent the changes of density corresponding to the changes of temperature. Should the temperature vary at any time after the hands have been set as described, the operator has only to adjust the hand 11 to the temperature, as shown by the immersed thermometer by means of the hand wheel 5 and the shaft 4 will also be turned with the spindle 12 so as to adjust the volume of the cylinder in each compartment as required to deliver the required weight of oil into the tins when the compartments are emptied. The hand 10 points always by this device to the density of the liquid under the existing conditions. The shaft 4 is supported in bearings, where it passes through the dividing Walls of the compartments and at the end compartment nearest tothe hand wheel 5 is packed so as to be 011 tight by means of the stuffing box and gland 15.

Oil is admitted to the compartments from a reservoir 38 through a main valve in the valve casing 16, which is opened and closed by the spindle 17 turned by the hand wheel 18. An air vessel 39 is attached to the reservoir to absorb any shocks on openmg or closing the main valve. WVhen the main valve is opened, oil flows into the central chamber and when this is filled flows lnto the adjacent chambers on either side through the semi-circular spaces 19 provided as shown at the top of the junction of two ad acent compartments. Air escape valves 20 (Figs. 1 and 4) are provided at the top of the end compartments. The valves are weighted so as to remain open against the escaping air but so as to close under the flow of oil which occurs when the compartments are all filled and the oil reaches the level of the valves. The weights tending to keep the valves open can be adjusted depending upon the head or pressure at which the oil is admitted, so as to minimize the amount of oil escaping by the overflow pipe 40. When the weights on the valves are seen to rise, the main valve 16 is closed by the hand wheel 18. The lever 21 is then pulled 'down to open by means of the common sliding bar 23 the air stop cocks 22 fitted to each compartment, which release any air confined in the spaces 19. The lever 21 in its lowest position lies in the path of the handle of the valve wheel 18 and prevents the wheel from being turned and the main valve 16 opened at the wrong time.

Vhen the compartments have been filled the hand wheel 24 is turned so as to move the sliding bar 25 to the right by means of the screwed rod 26, so as to lower the nozzles 27 into the tins placed below them. These nozzles are pulled down by weights 28 and the attached sleeves 29 slide over the pipes leading from the compartments. Projecting pins 32 on the sliding bar 25 press against the arms 31 of the two-armed levers. \Vhen the bar is moved to the left, the arm 30 of these levers is raised and by means of the rollers 33 lifts the bar 31, which raises the nozzles by the collars 35. When the sliding bar 25 is moved to the right, the weights attached to the nozzles cause the bar 34 to fall into the lower position, in which the nozzles are placed in the tins. In this position the slotted links 35 are moved by the pins 36 attached to the sliding bar 25 so as to open the stop cocks 37 on the discharge pipes of the compartments.

When the contents of the compartments have been emptied into the tins, the hand wheel 24 is turned in the opposite direction, the nozzles are raised, and the cocks shut.

In the construction of the machine shown, there are nine compartments, each compartment holding lbs. of oil, but the number and capacity of the compartments can obviously be varied as may be required for any specific purpose.
