Title: Improvements in controlling apparatus for compressed air brakes
IPC: B60T15/04
Filed: 1921-04-05
Abstract: 161,520. Seguin, E. April, 8, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Fluid-pressure.-The pressure in the trainpipe of compressed air brakes is adapted to be raised for releasing the brakes by varying the pressure in a small reservoir the operation corresponding to the equalizing reservoir action in applying the brakes. Fig. 1 shows valve mechanism adapted to effect both the application and release of the brakes in this way, comprising a slide valve E actuated by a piston D subject to the pressures in a reservoir H through the pipe g and to the pressure in the train-pipe G through the pipe f and passage f<1>. The valve E is adapted to connect the train-pipe connection f either with the exhaust port e or to the main reservoir by the chamber B and pipe h. Operation is effected by the manually actuated plug valve J which may make the following connections :-(1) The pipe h is connected to both the pipes G and g so that the train-pipe is charged without the intervention of the valve E which remains in lap position as shown since the reservoir H is charged simultaneously with the trainpipe, (2) the pipe h is connected only to the pipe g, thereby depressing the piston D to open the train-pipe passage f to the chamber B and thus to the main reservoir. When the pressure in the train-pipe has equalized with that in the reservoir H the valve E is returned to lap position by the spring F, (3) the pipe g is connected to the atmospheric port of the valve J thereby causing the piston D to rise and the valve E to connect the train-pipe to the exhaust port e until equalization has been effected, (4) the train-pipe G and the pipe g are both connected to the atmospheric port of the valve J thereby venting the trainpipe directly for a rapid application of the brake, the simultaneous venting cf the reservoir H. serving to keep the valve E in the lap position. In Fig. 2 the single slide valve E is replaced by separate lift valves P<1>, N<1>, operated by diaphragms O, N and controlling the supply and exhaust of the train-pipe G. The pipes G, h, g are connected as shown in Fig. 1. Fig. 3 shows a valve mechanism adapted for raising the trainpipe pressure only, for use with the existing driver's valve. The existing equalizing reservoir is used in this case and is connected at g, the train-pipe and main reservoir being connected respectively at f and h. To raise the train-pipe pressure the valve s<3> is depressed by the rod T to admit air from the main reservoir through the chamber R<3> and passage g<1> to the chamber Rand the equalizing reservoir thereby depressing the piston Q<1> and opening the valve r to admit main reservoir air to the chambers R<1>, R<2> and the train-pipe until equalization of this pressure with the equalizing reservoir pressure has been effected.

Title: Improvements in automatic controlling device for the slides of lathes and machine tools in general
IPC: B32B15/08
Filed: 1929-03-28
Abstract: 308,834. Soc. Anon. des Etablissements Cuttat. March 29, 1928, [Convention date]. Lathes.-In a lathe or other automatic machine tool having independently movable carriages actuated by hydraulic, pneumatic, electrical or other means, the carriage movements are controlled by means of a set of parallel sliding members which are actuated by the machine e carriages either directly or from some part of the carriage-actuating gearing. The lathe headstock is driven from a pulley 1 and the chuck 2 is actuated from a hydraulic cylinder 3 controlled from a valve-box 6 fitted with actuating-pedals 7, 8. A hydraulic pump P is driven by a belt 16 and is connected by a belt J with a pump 18 supplying fluid to the work. The hydraulic pump is connected to the various carriageactuating cylinders by pipes 19. The bed carries a longitudinal carriage D actuated by a cylinder 23 moving over a stationary piston 21. The carriage carries a screw 24 having adjustable abutments 26, 27 which coact with a fixed member 25 to limit the movement. The carriage D also carries a member 28 fitted with tappets 29, 30. An upper carriage E angularly adjustable upon the carriage D is actuated from a hydraulic cylinder 36 whose piston rod carries a rack engaging a pinion 33 connected by a. vertical shaft H to the operating- pinion 31. An adjustable stop device 42 - - 44 is provided to limit the stroke of the carriage E. The rack 34 is fixed to a control member 41 carrying tappets 45, 46. A third carriage F is operated by a cylinder controlled by a tappet 6 engaging a finger on the controlling valve. This carriage may be replaced by a compound carriage such as D, E. In operation, the carriage being in the position shown in Fig. 1, pressure is admitted to the cylinder 23 thus moving the carriage D towards the headstock until one of the tappets on the member 28 engages a finger 53 in the valve box 50 to stop the carriage D. A tappet on the member 41. at a predetermined point engages a finger 52 to cause fluid to be admitted to the cylinder 36 to start the carriage E, and the member 41 then moves independently of the member 28 until a tappet engages the finger 51 to stop the carriage E while a second tappet engages the finger 53 to restart the carriage D. The order and duration of the carriage movements may be modified according to the work to be performed and changes in the speed of either carriage may also be effected by suitable arrangement of the valve and tappet mechanism. In a modification, the sliding control members 28, 41 may be replaced by circular concentric members carrying the controlling tappets. One or both of the sliding members may carry tappets which act to return the carriages to their starting point and to initiate a fresh cycle, of movements.

Title: Improvements in self-acting spinning mules
IPC: D01H3/00
Filed: 1935-04-03
Abstract: 447,309. Spinning-mules. SACHSISCHE TEXTILMASCHINENFABRIK VORM. R. HARTMANN AKT.-GES., 27, Altchemnitzer Strasse, Chemnitz, Germany. April 3, 1935, Nos. 10354, 10355, and 10356. Convention dates, April 16, 1934, July 23, 1934, and Oct. 29, 1934. [Class 120 (ii)] In a self-acting mule having a differential reversing gear e on the tin roller shaft d and an arrangement for the stepless regulation of the spindle speed the drum f of the differential hitherto employed as brake disc during the twisting stage is connected with a device providing an adjustable force, e.g. a damping gear, by toothed drive, worm wheel drive, rope drive or similar positive means so that its speed of rotation may be regulated in a predetermined manner. The reversing gear e is driven by the main motor b through a rope i and comprises the drum f for braking the shaft d during the outward run, a brake drum g for backing-off and brake members h<1>, h<2>. The brake drum f is provided with a toothed rim l meshing with the pinion m of a damping gear n, e.g. a braking dynamo, the armature circuit of which is closed by a rheostat o, the rotary switching member of which is controlled during the outward-run and returned to its initial position during the run-in by a rack p, an unwinding rope or similar means. At the commencement of the outward run the armature circuit of the braking dynamo n is connected through the maximum resistance and develops little braking moment. As the carriage runs out this resistance decreases and the braking moment increases so that the drum f almost or completely stops. The brake member h<1> then stops the brake drum completely until the twisting is completed. Then the brake drum f is released and the member h<2> holds the drum g for backing-off. During the run-in the drums f, g are free and the switch of the rheostat o is returned to its initial position. In a modification, mechanical damping, e.g. by an adjustable hydraulic brake, may be employed, while alternatively the drum f may be positively connected to a speed regulator r, Fig. 6, or be driven by a variable speed compressed air motor. Specification 162,629, [Class 120 (ii)], is referred to. The Specification as open to inspection under Sect. 91 comprises also a modification in which the drum f is controlled by an eddy current brake. This subject-matter does not appear in the Specification as accepted.

The device comprises an upper platform 11 on the underside of which are mounted a plurality, e.g. 10, equi-spaced vertically disposed punch assemblies each of which comprises fixed inner and outer cylindrical members 12<SP>1</SP>, 22 between which is slidably mounted a spring-biased cylindrical member 23, and a corresponding number of coaxial non-rotatable piston assemblies 16 on the upper ends of which are mounted can positioning members 17, 18, positioned on a lower platform 13. The coupled platforms are mounted on a belt driven main shaft 6 and idler rollers 20 attached to the lower ends of the pistons 16 engage a cam ring 21 to impart reciprocating motion to the piston assembly during rotation of the platforms. Keys 28 are stacked in a pair of feed magazines 50<SP>1</SP>, tiltable for loading, located on a manually operated slide 42 which positions each loaded magazine in turn over a reservoir 38 which is located over the platform 11. A plurality of equi-spaced fingers 32 e.g. ten, are positioned alternately between ten key slots 33 formed in the platform 11 and protrude less than a key thickness above the top surface thereof to deflect a key into the preceding slot synchronously with the upward movement of the can. In operation, with the platforms rotating, sealed and sterilized cans with their axes horizontal are gravity fed along a guide device 26 and then twisted so that their axes are vertical at 27, into engagement with the plate 17, which is in its lowest position and raised during further rotational movement by the piston 16 into engagement with the cylinder 23 at which point a key 28 deflected from the reservoir 38 by the finger 32 falls into the cylinder 23 and is located in an oblique position as shown in Fig. 2. Continued raising of the can against the cylinder 23 causes the key to abut the fixed cylinder 22 which springs the key into a horizontal position between the crimped rims of the can lid. Continued rotation lowers the can which is subsequently deflected from the plate on to a further conveyer 31. In a modification the key stacking unit comprises a pair of inclined rods 58 along which the keys are gravity fed to a key guiding slot 54 in a block 53 positioned above the platform 11. The keys are initially supplied in batches arranged along a metal strip to facilitate loading of the feed units. The reservoir accommodates sufficient keys to cover the change-over time from one stack to the other.
