Abstract: 1,011,758. Drilling machine details. SOC. D'ETUDE ET DE CONSTRUCTION DE MACHINE OUTILS. June 25, 1964 [July 5, 1963], No. 26297/64. Headings B3B and B3C. A drilling machine spindle 1 is moved axially at a fast approach rate by a pneumatic piston 8 10 , and the rate is reduced during drilling by a dashpot, comprising an hydraulic piston 16. The spindle is splined to a sleeve 2 at 1 10 , and the sleeve is driven through pulleys 3, 4 and belt 5, by an electric motor 6. A second sleeve 8 1 , 8 2  is axially displaceable with spindle 1 in a casing 13, and has the piston 8 10 , 16 1  secured thereto, or formed thereon. Sleeve 8 has an abutment 8 20 , and an adjustable stop nut 18, screwed thereon. Piston 16 slides in cylinder 17, the ends of which are connected through passages 19-21, the latter passage containing a throttling valve 22. Passage 21 is connected to an oil tank 25, and a by-pass passage 23 containing a one-way ball valve 24, is connected to the tank, and also to passages 19, 20. In operation, air is supplied to the right-hand end of cylinder 12, Fig. 1, and sleeve 8 along with spindle 1 is fed at a rapid rate. Nut 18 strikes the end of sleeve 16 which moves to force hydraulic fluid through passage 19, past valve 22, and into passage 20, and the feed rate is reduced. When the drilling is completed the air supply to cylinder 12 is reversed and the spindle is retracted at a fast rate, with the hydraulic fluid passing freely from passage 20 to passage 19 through by-pass 23. Sleeve 8 has a pin 28, Fig. 3, projecting from it which carries a collar 29. Adjustably mounted in the collar is a rod 30 with an actuator 31 secured thereto, for cooperation with a micro-switch 32 to reverse the fluid flow to cylinder 12. A second rod 35 is adjustably carried by collar 29 and supports an actuator 34, which co-operates with a second micro-switch 33 to operate an audible or visual signal, which indicates that sleeves 8 and 16 have returned to their initial positions, Fig. 1. The starting switch in the control circuit may be cam-actuated, and a manual switch may also be provided. A delayed opening relay for switch 32 may be provided where it is desired to cause spindle 1 to dwell in its advanced position.

Title: Improved device for connecting one or other of two driving members to a driven member
IPC: F16D11/16
Filed: 1952-10-22
Abstract: 713,155. Positive clutches; linkwork. GENERAL MOTORS CORPORATION. Oct. 22, 1952 [Oct. 31, 1951], No. 26483/52. Classes 80 (2) and 80 (3) Two turned driving members such as concentric shafts 13, 17 used, e.g. in the control of an aircraft power-plant ;are drivingly connected to a similar single driven member, such as a concentric shaft 19, by a dog 37, pivoted at 39 to and embracing each side of an arm 36 of the driven shaft 19, and having a pair of cam-faced dog-teeth 44, 45 which, by riding selectively over high or low cylindrical surfaces 51 &c. on discs 33, 34 fast on the respective driving shafts 13. 17 on either side of the arm 36, tilt the dog 37 one way or the other to cause one or other of the dog teeth 44, 45 to fall into driving engagement with an appropriate one of two notches 48, 49 one on each disc 33, 34, whereby the driven shaft 19 is driven by whichever one of the two shafts 13, 17 is in advance of the other in either direction within a range of movement. Such range is limited by engagement of either end 74 of a flat-based recess cut in the lower face of the disc 33, with a fixed pin 71. In Fig. 2, the front disc 33, is in its initial position against the stop 71, and the rear disc 34 very slightly advanced anticlockwise therefrom. A high cylindrical surface 54 ahead of the drive-notch 48 in the front disc 33 underlies one dog-tooth 44, whereby the dog 37 is tilted to engage the other dogtooth 45 in the drive-notch 49 of the rear disc 34 If now the shaft 17 and hence the rear disc 34 are alone moved anticlockwise in a range limited to 90 degrees by the lower cylindrical surface 51 of the front disc, the driver shaft 19 will be taken along therewith, clutch engagement of the active dog-tooth 45 being maintained by the idle dog-tooth 44 riding over the high surface 54 of the front disc 33. If however the shaft 13 and hence the front disc 33 are alone moved anticloakwise, an inclined surface 56 at the trailing junction of the high and low cylindrical surfaces 54, 51 on the front disc 33 cams the dogtooth 45 upwardly out of the rear disc notch 49 just as the front disc notch 48 comes under and receives the other dog-tooth 44, which latter thereafter transmits drive from the shaft 13 and front disc 33 to the driven shaft 19, the idle dogtooth 45 now riding on the high cylindrical surface 58 of the rear disc 34 to maintain clutching engagement of the active tooth 44. Travel range with this disc is limited only by the pin 71 and is greater than that of the rear disc. Like the front disc 33, the rear disc 34 has a low cylindrical surface 52 for part of its periphery leading to its high cylindrical surface 58 by cam inclines at each end, whereby the above action takes place at any point in the range in either direction to ensure that the leading shaft 13 or 17 is always automatically clutched to the driven shaft 19. All the. shafts carry operating arms 22 and the driving shafts 13, 17 also carry cams 26, 27, the latter operating switches 29, and a gear 32.

Title: Improvements in automatic exchange systems
Inventor: BRAY FREDERICK HARRY
IPC: H04Q3/00
Filed: 1960-08-02
Abstract: 957,198. Automatic exchange systems; magnetic storage matrices. STANDARD TELEPHONES & CABLES Ltd. Aug. 2, 1960, No. 26748/60. Headings H3B and H4K. Separate magnetic matrices are used as meter stores, Fig. 1, and as class-of-service stores, Fig. 2, for a group of 200 lines, the two stores being operated by separate pulses transmitted over leads P1 to P200 individual to the lines and common to the two stores. Time position T1, T2 and T3, T4 (Fig. 4) are allotted respectively to the class of service store and to the meter store, the time position being marked in the appropriate stores by half-write drive pulses which, unaided, cannot switch a core. A core is switched by a bias pulse, slightly longer than a drive pulse. Class-of-service indicator, Fig. 2.-Each classof-service is represented by one or more columns of cores. Lead P1 from line 1 is linked with two cores indicating that it is a call box (CB) and has a barred trunk restriction (BT). When a free register is seized by line 1, it transmits bias pulses T1, T2 of opposite polarity in succession over P1 and the two cores are switched and restored. Amplified output signals on leads CB1, BT1 act through OR gates to switch toggles CB, BT. The toggles transmit the signals to the register and are restored by a reset pulse as shown. If the registers operate one at a time, no special arrangements are necessary to steer the signal to the correct register. Meter store, Figs. 1 and 3.-Each of the leads P1 to P200 is linked with a column of six cores capable of storing up to 63 units in binary rotation. When a call has matured, the number of bias pulse pairs T3, T4 received signifies the charge. The first bias pulse T3 sets all the cores R1 to R6 to " 0 " and transfers the number n stored therein to an auxiliary store, Fig. 3, comprising toggles TG1 to TG6. The ADD pulse increases the number stored by 1 and the T4 pulse biases transistors TS1 &c. to transfer the number n + 1 to the original store R1 to R6. A reset pulse restores the auxiliary store to normal. The auxiliary store may be common to a number, say 5, of meter stores. The information may be transferred from the store to a central point for automatic accounting.

Title: Improvements in or relating to separating and delivering mechanism for riveting, nailing and like machines
IPC: B21J15/10
Filed: 1933-09-28
Abstract: 425,242. Nailing or riveting machines. STEELS & BUSKS, Ltd., Ariel Works, Temple Road, North Evington, and HUGHES, A. C., Lyndhurst, Humberstone Drive, both in Leicester. Sept. 28, 1933, No. 26754. [Classes 43 and 89 (iii)] A separating and delivery mechanism for riveting, nailing, and like machines comprises a separator, constituted by a movable section of the raceway, formed with a passage for the rivets, and an abutment arranged to interrupt movement of the rivets along the raceway. A small angular oscillation of the separator releases one or more rivets from the abutment and passes them to the lower portion of the raceway. The separator comprises a shank 6 rotatable in the head 11 of the machine and a head 1 which is flush with the raceway 2 and has a T-shaped passage 8 for the rivets similar to, and normally aligned with, the passage 7 of the raceway. An abutment 9 secured at one side of the raceway has a hooked end 9<a> which overlies the head 1 in such a position that the lowermost rivet a<1> in the raceway can enter the passage 8 in the head, where it is held by the abutment, Fig. 4. A small oscillation of the separator serves to withdraw the rivet a<1> from the abutment, the other rivets a then being held back by the solid head of the separator, whilst the rivet a<1> passes down the passage 8 until arrested by the solid portion of the raceway, Fig. 5. Return oscillation of the separator releases the rivet a<1> into the lower portion of the raceway, and allows a fresh rivet to enter the passage 8 as far as the abutment 9. In modifications, the passage 8 is curved, or the lower portion of the raceway is offset, so that the separating movement of the separator serves also to release the separated rivet into the lower raceway portion. The separator normally is held in the position shown in Fig. 4 by a rod 14 and spring 16, and is given its separating stroke by a yielding striker 20 carried by the driver-actuating arm 18. Means is provided for adjusting the stroke of the slide 23 which carries the chuck 4. This consists of a stepped collar 24 on the head 11 which is adjustable to bring steps of different heights into co-operation with a pin 25 on the slide 23. Reference has been directed by the Comptroller to Specifications 14724/02, [Class 89], and 155,361, [Class 89 (iii)].
