Title: Improvements in and connected with Plunger Pumps.
Inventor: LIETZENMAYER OTTO
Filed: 1906-04-05
Granted: 1907-01-03
Abstract: 8192. Lietzenmayer, O. April 5. Governing or controlling pumps; delivery, regulating.-Comprises a pump having a working and a counter plunger, the latter being controlled so as to vary the volume of liquid delivered. As shown in Fig. 1, a is the working-plunger and b the counterplunger, the latter engaging with the carrier c. The governor is shown in the mid-position; when the plunger a moves down, the plunger b descends until the stop d comes against the collar l, after which the plunger a only moves down to the end of its stroke. On the up-stroke, the plunger a rises alone until the carrier c engages with the plunger b, which then ascends. The volume of liquid delivered corresponds to the difference in the strokes of the two plungers. The governor adjusts itself without shock when the plunger is at rest. As shown in Fig. 2, the antifriction roller c takes the place of the carrier c, Fig. 1.

Abstract: 22,338. Thorner, W. Oct. 10, 1905, [date applied for under Patents Act, 1901]. Optical instruments; lenses; telemeters. - A focusing-device for photographic cameras consists of two small concave mirrors I, II, which may form part of one spherical surface Z, having a focal length approximately equal to that of the lens, and a third divided mirror III, of a focal length about half that of the lens, the two halves of which are mounted parallel to the mirrors I, II. The latter, are mounted in the plane of the plate on a slat X which can be turned down when not in use. The divided mirror is mounted above the lens on an arm which may be turned down when desired and moves with 'the lens while focusing. The arrangements are such that, when the focusing is correct, the image of vertical lines of the object are continuous in the two halves of the mirror III. In place of a divided image, two complete dim images may be obtained by arranging two mirrors, one being transparent to reflect the light from the ends of the base line. In a modified construction, a prismatic lens is mounted on each side of the objective, and a similar divided lens in the plane of the plate.

Abstract: 25,078. Ashworth, J. Nov. 7. Pumps with reciprocating barrels; plunger pumps; delivery column, balancing.-Relates to the invention described in Specification No. 7281, A.D. 1902. The rising mains 3, 4 are provided with clack valves 25, 26, beneath which are fixed tubular extensions provided with receivers 22, 23 working over fixed pistons 24. The parts 18, 19 of these extensions work over the parts 7, 8 of fixed U-shaped pipes 5, 6, having parts 10, 11 for receiving the plungers 15, 14 connected to the oscillating mains 4, 3 which are connected by bell-crank levers, as shown. Pipes 1, 2 lead from the bottom of the well &c. to the pipes 10, 11, and clack valves are placed at 12, 13, 16, 17. The capacity of each receiver 22, 23 is greater than that of the corresponding part 18 or 19, so that the water in these parts can flow into the receivers as the receivers fall, and there is no upward pressure to open the clack valve 25 or 26 as it descends. The column of water above such valve thus acts as a descending weight to assist the corresponding plunger 14 or 15. Cocks 30, worked by fixed tappets 32, 33, show if there is any leakage past the valves 25, 26. Cocks 34 enable the water to be cut off during repairs to the clack valves beneith them.

Abstract: 27,728. Spicknall, M. O., and White & Co., J. G. Dec. 5. Electric railways and tramways on the slot-circuit system, in which the conduit is arranged beneath the slots of one of the track rails. Conduits; points and switches.-Con-. sists in means for strengthening o r supporting the combined track-rail and conduit point tongue. The point tongue d, shown in side view and plan in Figs. 1 and 3 respectively, is carried by, and pivoted at e to, the cantilever c secured to the girder-like casting a. To provide further support for the tongue, a bar h is pivoted to the end of the cantilever, and is kept in contact with the tongue by the dovetail projections and corresponding recesses m. The tongues are connected for oscillatory movement by the projection n, which is so placed that both tongues move simultaneously through a distance equal to their width plus that of the slot. To reduce the stress on the cantilever, a removable support p, Figs. 3 and 5, is arranged near to its free end so as to fit within the slot o. The support is pivoted at u and normally kept in the slot of the cantilever by the spring v, its sides being shaped so that it can be easily deflected out of the way by a passing plough. To prevent the slot tongue from being tilted, a metal wedge r and plates s, t are arranged as shown. The extreme end of the conduit tongue is further supported by metal plates y, Fig. 7, attached to the rail flanges. The tongue d is extended backwards, as shown at f, Fig. 1, so that it can be controlled by a spring if intended to be used as an automatic trailing point.

Fig. 4 shows a plan of the general arrangement, in which one driving-disc c fixed to the motor shaft a gears with one friction wheel, and the other disk d, which is connected to the shaft by a spring clutch and is adjustable longitudinally thereon, gears with the other driven wheel. The friction wheels b<2> are connected one to each road wheel. The apparatus for adjusting the disk d is shown in Fig. 1. The end of the shaft a is hollow and contains a push-rod 17, which may be moved in and out to effect the engagement or disengagement. The inner end of the rod 17 is forked, and a wedge 20 is secured between the two prongs of the fork. When the rod 17 is pulled outwards, the wedge forces the pressure blocks 21 outwards through openings in the shaft a a so that they engage between double cones, one of the cones being secured to the shaft a and the other forming part of the disk d. The disks c, d are thus moved towards one another against the resistance of the spring 23. The disk d is clutched to the shaft a by means of a spring clutch 16 and a ring 15, integral with one of the double cones.

Actuating pumps; delivery, regulating; well pumps.-A pump p for use in sinking wells, shafts, &c, is constructed in a compact form by arranging a vertical spindle motor to drive three wormwheels, each operating two plungers. Pairs of plungers, the motions of which are synchronous, work in the same chamber, each chamber being provided with separate inlet and outlet valves. Fig. 1 shows a par t sectional elevation of the pump. The spindle of the vertical m o t o r A carries a worm B driving three wormwheels C, C', C<2> spaced around the axis of the motor spindle, as shown in Fig. 3. The shafts D of these wormwheels are placed at varying heights to minimize the wear on the worm. The wheel rims may be made adjustable in relation to the centres, and the vertical heights of the axis of the wheels may also be made adjustable, to facilitate accurate setting. Each wheel shaft carries overhanging crank-pins F operating the rams H, H<1>, H<2> through connecting- rods G, G<1>. The cranks are fixed at 120 degrees apart in order to bring adjacent cranks on independent shafts into synchronism so that the six plungers work together in pairs controllable by three sets of suction and delivery valves as shown in Fig. 2. The capacity of the pump may be varied by putting the plungers out of synchronism. The actuating-mechanism is cased in, and the parts are lubricated by splash lubrication or by a pump L ; the oil used may be cooled by a portion of the water pumped.

Title: Improvements in Apparatus for Automatically Controlling the Temperature in Buildings and other Places.
Filed: 1908-02-25
Granted: 1908-08-13
Abstract: 4261. Marks, E. C. R., [National Regulator Co.]. Feb. 25. Controlling automatically air for, treated by heating; valves.-In apparatus for controlling the temperature in buildings, in which a fluid-pressure motor 7 regulates dampers 8, 9 admitting hot and cold air to a room the supply of fluid is controlled by a thermostat 2, in such a way that the movement of the motor is retarded or accelerated. The pressure of the fluid in a supply pipe 4 tending to open a valve 20 is balanced by the back pressure in the thermostat, and by the tension of a spring 19. A rise of temperature diminishes the tension of the spring, and allows the fluid to open the valve and pass to the motor, thereby closing the damper of the hotair chamber. At the same time the back pressure in the thermostat is increased and assists the spring 19 in closing the outlet of the supply pipe 4. In this way a vibrating action is set up, and the movement of the motor is retarded. Similarly by reversing the connexions the movement of the motor may be accelerated. In a modified system, the two pipes 4, 6 are replaced by a single pipe, a restriction being formed in the pipe leading from the tank, and the outlet pipe of the thermostat opens to the atmosphere.
