IPC: F16C17/06
Filed: 1931-06-08
Abstract: 380,440. Thrust bearings; lubricating. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. (Assignees of Gordon, T. W.; 1146, Waverly Place, Schenectady, New York, U.S.A.) June 8, 1931, No. 16681. Convention date, June 7, 1930. [Classes 12 (i), 12 (ii), and 12 (iii).] A vertical shaft thrust bearing has a plurality of concentric ring members 23, 24, 25 fixed to a shaft collar 4 and co-operating with a set of corresponding ring members 19, 20, 21 which are mounted by springs 18 on a supporting ring 10 and positioned by loose dowels 22. The bearing faces of the rings 19, 20, 21 are divided by radial channels 29 which for any ring are closer together than those on the adjacent inner ring. The ring 10 has radial passages 14 and vertical ducts 17, the latter leading to annular spaces between the rings 19, 20, 21. Secured to the perimeters of the rings 19, 20 are baffles 30, 31 which extend upwards and bear against the inner edges of the rings 24, 25 respectively. The bearing is surrounded by an annular stack of radiator pipes 9 through which cooling fluid is circulated, and the whole assembly is enclosed within an oil bath 5. In operation, cooled lubricant passes through the passages 14, 17, and flows between one pair of co-operating ring members only. Lubricant flowing between the rings 19, 23 is deflected by the baffle 30 into radial passages 28 in the rings 24, 25, and that flowing between the rings 20, 24 is deflected by the baffle 31 into the passage 28 in the ring 25 ; the lubricant from the passages 28 flows over and through the cooler 9. The circulation of lubricant is facilitated by the pumping action of the rotating parts.

Title: Improvements in arc discharge apparatus for regulating, rectifying, amplifying, or modifying the frequency of alternating currents
IPC: H02M11/00
Filed: 1926-07-02
Abstract: 254,746. Soc. des Relais Ó Arc, (Assignees of Toulon, P. M. J.). July 3, 1925, [Convention date]. Arc and spark-gap apparatus, arrangements of.-Power from an alternating current supply 1, 2, Fig. 1, to a load 5 is regulated and, if desired, rectified by inserting in series with the load a spark-gap 6, 7 across which an arc is established by auxiliary means, the arc breaking at the end of the half cycle of the supply. By varying the phase of establishment of the arc, the supply of power is varied, and by ensuring that the establishment occurs only during alternate half cycles, a direct current is obtained through the load 5. The arc is established by introducing an instantaneous voltage into the circuit of the spark-gap 6, 7 by means of coils 8, 11, the latter being in a spark-gap circuit including a gap 12 and condenser 13 fed from a transformer 14, 15. By altering the phase of supply to the transformer 14, 15 the phase of establishment of the arc is varied, and by making the gap 12 asymmetrical the arc is only established on alternate half-cycles. The system can be adapted to a three phase supply connected through a three phase to six phase transformer, the six phase side being star connected and the load being connected to the star point and to six spark-gaps each associated with one of the six phases. The sparkgap 6, 7 is constructed as shown in Fig. 2. Concentric copper tubes 17, 18 constitute the electrodes, cooling liquid being circulated in the spaces 16, 20 and a suitable gas being passed through the arc space formed between the tubes. A solenoid 19 energized by direct-current causes the arc to rotate round the tube 16.

Abstract: 866,973. Attaching handles &c. to pottery articles. SERVICE (ENGINEERS) Ltd., and DOWLEY, A. May 30, 1957 [May 31, 1956; May 11, 1957], Nos. 16816/56 and 15029/57. Class 87(1) In apparatus for affixing e.g. a handle to a body portion of a ceramic article, the operator places a handle blank H in a presenting device A in a loading position, the presenting device moves away from the loading position and presents the blank to a trimming device B, and the blank is trimmed and then transferred to a mould M, which attaches it to the body portion. The presenting device A comprises an open topped mould 30 having a recess 26 for locating a handle blank. The mould 30 is carried by a rod 32 slidably mounted in a block 34 fixed to a rotatable shaft 36. Pivoting movement of the mould 30 is controlled by a lever 48 acted on by a cam 24, and sliding movement is controlled by a spring 40 and an L-shaped member 54 acted on by a cam 22. When the blank H is presented to the trimming device B, blades 4 are moved to a partly closed position and partly sever the blank. The blades 4 are arranged so that when closed they form a contour corresponding to that of the cup or like article to which the handle is to be affixed. The blades 4 are so mounted on their operating arms 230, 232 as to be adjustable in four different senses. The trimming device B with the handle blank supported between the partly closed blades 4 is then rotated about a vertical axis to transport the blank to a position (Fig. 5) over the attaching mould M. The blades 4 then close and the trimmed blank is supplied to the mould M which closes and grips the blank. Slip is applied to the ends of the blank by a slip-applying device C and the handle applied to a cup supported on a chuck E by apparatus similar to that in Specification 728,072. Closing of the blades 4 is controlled by a cam 20 through a two-armed lever 96, 200 acting on a vertically slidable rod 82 which carries rollers (as 92) bearing on the blade operating arms 230, 232. Rotary movement of the trimming device B is controlled by a spring 64 and by a cam 18 through a two-armed lever 208, 212.

Title: A load lifting mechanism for lift trucks
IPC: B66F9/08
Filed: 1957-05-28
Abstract: 818,456. Masted list trucks. CLARK EQUIPMENT CO. May 28, 1957 [June 4, 1956], No. 16883/57. Class 78 (3). In a fork lift truck the lifting carriage 36, Figs. 2, 3, with load-engaging forks 37 is slidably mounted on a pair of rigidly-connected I-girders 21, which in turn are slidably mounted on I-girders 18, slidably mounted on channel members 13 rigidly attached to the truck. The rear flanges 18b, 21b, Fig. 4, of the movable uprights are disposed within the channels of uprights 13, 18 respectively. Rollers 38, 39 on the lifting carriage, and rollers 23, 25, 27, 29 on the uprights, are mounted in vertical planes with the axes skew to the transverse axis of the truck, as seen in plan in Fig. 4. This arrangement is said to give better wear characteristics on the rails. A single pair of rollers 44 prevents the carriage tilting under uneven loading. The mast is extended by chains 50, Figs. 2, 3, attached at 52 to a crosshead 53 on the piston of an hydraulic ram 51, then passing under sprockets 56 attached by rods 57 to the base, over sprockets 59, Fig. 3, on the cross-head, under sprockets 60 and over sprockets 61 attached to the upper mast elements 21, the ends being attached to the load carriage 36. The cross-head is guided in rails 65 attached to the uprights 21, and during its initial movement the movable uprights are locked to the fixed member 15 by a latch 71, Figs. 2, 8c, which is pivotally mounted midway between the upper ends of the uprights 21 and whose face 76, Fig. 8c, is held in engagement with an ear 81 on the member 15 by a spring-loaded plunger 82 pressing on arm 74 of latch 71. During this period the lifting carriage moves on the temporarily fixed members 21. When the cross-head strikes arm 78 of latch 71 the faces 76, 81 are disengaged and face 77 engages a recess in the cross-head, thereby locking frame 21 to the cross-head. At the same time latch 91, also pivotally attached to the frame 21, is moved in the opposite direction through the push-rods 89, 90 and lever 86 (see Fig. 4). This allows a projection 97, Fig. 4, on the lifting carriage to pass the surface 105 and strike arm 95 of latch 91, pushing it and latch 71 back into the Fig. 8c positions, and thereby disconnecting frame 21 from the crosshead and latching it to the lifting carriage by virtue of surface 105 engaging projection 97. These positions are held until the carriage is fully extended, the uprights 21 entraining uprights 18 for the last part of the motion through stop blocks 108, 26, Fig. 2. For the downward motion the movements are reversed, latch 91 being held in its clockwise position initially by a weight on arm 93, and latch 71 being held in its clockwise position when the cross-head is engaging arm 78, by a leaf spring 98 which engages the back of the cross-head. Latch 71 is fmally locked in the position of Fig. 8c by the spring-loaded plunger 82. Specifications 818,457 and 818,458 are referred to.

Filed: 1930-05-31
Abstract: 353,992. Bottle-washing machines. ADAM, H., 67, Keplerstrasse, Heidelberg, Germany. May 31, 1930, No. 16917. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 9, 1930.] [Class 138 (i).] A bottle-washing machine of the type having an endless track operates in a manner such that the bottles remain with their mouths downwards throughout the passage on the track, the operations of soaking, rinsing, squirting, steaming, drying, &c. being carried. out while the bottles are in this position. The air may be discharged from the bottles by tubes to assist the soaking liquids to enter the bottles. Air or compressed gas may also be employed to assist the emptying of the bottles. Two forms of apparatus are shown in Figs. 1 and 3, both forms having the same arrangement for maintaining the bottles with the mouths downwards. For this purpose, the bottle holders are carried from a bottom track to an upper track by a feed-wheel 5 and curved track 6, and are pushed forwards after leaving the feed-wheel by the pressure of succeeding bottles until they reach a wheel 4 which, operating in conjunction with a curved rail, transfers them to a delivery table 12. A loading table 2 feeds a bottle to a position 3 on the wheel 4, and it is carried along in the direction of the arrow to the position 3a where it automatically pushes forward the row of bottles, in the construction shown in Fig. 1. In this construction, the lower row is subjected to the action of squirt tubes 7 arranged in tanks 12 and the upper row to the action of tubes 9 in tanks 8. From the tanks 8 the liquids flow over the outside of the bottles, as indicated. In the construction shown in Fig. 3, the bottles on the lower track are alternatively raised into the position 3d, moved longitudinally, and lowered again over squirt tubes 25. The raising and lowering is effected by cams 15 acting in conjunction with rods 16 provided with rollers 17 moving in slots 18 and carrying lifting bars 19. The bars have notches for engaging hooks 21 on the bottle holders. Movement of translation is effected by levers 23 also acted on by the cams 15.

Abstract: 439,847. Fuel-injection pumps. SULZER FRERES SOC. ANON., Wintherthur, Switzerland. June 12, 1935, No. 16975. Convention date, June 20, 1934. [Class 102 (i)] A fuel-injection pump for a reversible internal-combustion engine is provided with control means whereby at loads above a predetermined value only the timing of the commencement of injection is varied in accordance with the load, whereas at loads below this value not only the timing of commencement, but also the timing of the end of injection are adjusted in accordance with the load. The spring loaded plunger 8 is actuated by a link 7 carrying a roller 6 engaging the symmetrical cam 3. The suction valve 13 is allowed to close by the movement of a rod 27 engaging an abutment 26 on a sleeve 221 mounted on an eccentric 25. The sleeve 221 is oscillated by an adjustable link 29 connected to the spindle 24. The closing of the valve determines the beginning of the injection. A byepass valve 20 is opened to end injection by similar gear, the sleeve 31<1> being oscillated by the link 38. The eccentric pins 25, 32 are geared together by quadrants 37, 38 and adjusted by the governor to vary the timing. The clearance 36 allows a certain adjustment before the valve 20 is actuated. The arrangement of the valves and actuating mechanism may be varied. The same law of regulation may be attained by controlling the suction and byepass ports by the plunger or a side valve.

Title: Improvements in tumbling method and apparatus for processing articles
IPC: B24B31/02
Filed: 1944-09-07
Abstract: 589,052. Rumbles and tumbling- barrels. LUPO, J. Sept. 7, 1944, No. 17126. [Class 60] A method of processing articles consists in first tumbling them in a completely closed receptacle for a pre-determined length of time, together with a tumbling mixture, said mixture comprising particles of material which may be coated with an abrasive and tumbling elements of larger size than said particles, both the particles and the tumbling elements being of smaller size than the articles to be processed, then, without removing the articles to be processed, continuing the tumbling operation in the same receptacle while simultaneously separating and discharging the particles from the articles and the elements of the tumbling mixture in the receptacle, whereafter tumbling of the articles in said receptacle may be continued with the tumbling elements alone. Apparatus comprises two horizontally mounted tumbling barrels B, selectively driven through clutches E and countershaft D by electric motor C. The barrels are enclosed in a openfronted housing A, having a partition 13 between the barrels, the compartments thus formed being provided with doors J comprising hinged sections 30 and 31. Each barrel has a charging opening 15 which can be closed either by a solid plate 16 or a screen mesh panel 17. Sieves F, G and a trundle box H are provided inside the housing under the barrels. In operation, the door J is opened, and the mixture of articles, tumbling elements and particles introduced into the barrel through the charging opening which is then closed by the solid cover. After tumbling for the required time, the solid cover is removed and replaced by the screen mesh panel. On further rotation of the barrel, the particles escape through the mesh, pass through the sieves, and are collected in the trundle box, tumbling proceeding with the articles and tumbling elements. After completion of this operation, the contents of the barrel are discharged, the articles being retained by the sieve F and the tumbling elements by the sieve G. In a modification the tumbling elements are of two sizes, and two screen meshes are provided, one permitting passage as before of particles, and the other of the smaller tumbling elements.
