Title: Improvements in means for delivering mails from moving trains
IPC: B61K5/06
Filed: 1922-04-25
Abstract: 190,678. Harkcom, H. W. April 25, 1922. Transferring articles to and from trains in motion.-Relates to automatic exchange apparatus for delivering mails from moving trains of the type in which a mail carrier 3, Fig. 1, supported on an arm 2 projecting from the side of the mail van engages inclined members such as rails or ropes 5 at the side of the track and is thereby lifted from the supporting arm, which then returns to a, folded position The carrier 3 for the mail box 6, Fig. 15, is in the form of an inverted T-shaped member of which the vertical limb 30 carries rollers 4 for engaging a pair of inclined rails 5 of the receiving apparatus, while the horizontal limbs 32 have projecting pins 33 engaging eyes in the supporting arm 2. The arm 2 is secured to a vertical stanchion 7, Fig. 8, rotatably supported in bearings 8 on the mail van by quick-threaded screws 9 and adapted to be locked in its projecting or operative position by a plunger 10 engaging a slot 11 in the side of the van, and connected by a rod 14, universal joint 16 and a rod 15 having a quick-threaded portion 17 to a rotatable drum 19. After the mail has been detached from the arm 2, the drum 19 is adapted to engage a spring-pressed member 21 mounted' on supports 22, Figs. 1 and 4, and is frictionally rotated so as to cause the withdrawal of the plunger 10 from the slot 11, thus releasing the stanchion 7, which then automatically returns to its folded position partly under the influence of a weighted cable, and partly by its own weight co-operating with the quick screw-threads 9. Instead of being automatically released. the locking- means for the arm 2 may be manually operated, or a modified automatic means, as shown in Fig. 18, may be employed. In this construction, vertically-moving locking-pins d are held in recesses by the weight of the mail box until the latter is detached, when the pins d are released by controlling springs. The receiving rails 5 are provided at the " take-off " end A with converging guides 40 for positioning the carrier 3 and slope upwards to a highest point B and then downwards to the delivery point C. At the latter point the carrier is brought to rest by a braking device comprising pivoted pawls 41, Figs. 15 and 16, on the limb 30 adapted when depressed to engage recesses 43 in the rollers 4 but normally held upwards by spring pins 43<a>. When the carrier 3 reaches the point C the pawls 41 engage an arch 44a on the standard supporting the rails 5 and are depressed to enter the recesses 43. A further braking arrangement comprises two converging rails 47 one or both of which is adjustably positioned by means of a screw 45.

Abstract: 695,326. Radio transmitting and receiving apparatus; valve super-regenerative circuits. BENOIT, J., and SZEPESI, Z. May 18, 1951 [May 26, 1950], No. 11703/51. Class 40 (v). A portable short-wave transmitter-receiver comprises a crystal-controlled oscillator for transmission, and a super-regenerative receiver, the crystal being short-circuited during reception. With the send-receive switches at E the transmitter comprises an oscillator T1 controlled by the crystal 14, followed by a high-frequency amplifier T2. The grid of the modulating valve T3 is connected to a piezo-electric throat microphone 33 and the output from T3 is amplified by the valve T4 and modulates the screen of valve T2. The headset 30 is connected via capacitor 76 to the anode of valve T4 to provide sidetone. With the send-receive switches at R the crystal 14 is short-circuited and the screen grid of T1 disconnected, and the receiver comprises the valve T2 which becomes a high-frequency oscillator interrupted by means of the grid circuit which has a time constant dependent on the resistor 19, inductance 20, and capacitor 21, the inductance 20 preventing the grid from being earthed for highfrequency through the capacitor 21. The aerial 11 is connected to the anode of valve T2 and the detected signal appears across the inductance 23, is amplified by valves T3 and T4, and applied to the headset 30 via transformer 31. In an alternative arrangement, Fig. 7 (not shown), the functions of high-frequency amplifier for transmission and super-regenerative detector for reception are carried out by separate valves. Power is provided by a twovolt accumulator 40, a series resistor 41<SP>1</SP> dropping the voltage to 1.4 volts for the heaters, and a vibrator 43 providing the H.T. An additional winding on the transformer 44 provides through a rectifier 56 a negative voltage to bias the valve T4. The accumulator can be recharged without removing it from the case by connecting the charger to a coaxial attachment 97 and operating the switch 92. The apparatus fits into a small metal box and is fastened by straps into a shelf-like carrier of aluminium which is attached to the chest of the operator, the rod aerial being arranged well clear of the operator's body.

Abstract: 217,009. Rogers, F. H., (Vortex Mfg. Co.). May 1, 1923. Paper bags and the like, making.-Conical paper cups are formed by winding between heated conical rollers blanks of the form shown impregnated with paraffin-wax or other waterproofing medium and coated on the area 20, shown with acidified starch or other adhesive. The edge 15 is tangential to the substantially circular arc 17, 18, of greater radius than the arc 18, 19, which is practically in contact with the edge 14 in the neighbourhood of the cone centre 19. The adhesive is so spaced from the blank edge, except at the arc 18, 19 and a sector 24, that under the forming-pressure it spreads to the edge, particularly at the point 19, which it nearly approaches. At the arc 18, 19 is left a free edge which tends to lift from the finished cup and so separate the members of a nest of finished cups and prevent adhesion. The sector 24 is left to allow space for the clasp of gripping-members during making, and occurs at a part of the blank which is covered by a succeeding convolution of the cup flap when the cup is made.
