Filed: 1931-09-24
Abstract: 379,233. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Sept. 24, 1931, No. 6768/32. Divided on 380,944. [Class 130.] A wrapped cigar is re-rolled between a pair of vertical plates, one plate having a lower supporting flange on to which the cigar is delivered and means being provided for effecting vertical reciprocating movement between the plates during their engagement with the wrapped cigar. An arm 49 delivers the cigar between plates 67, 68 when a finger 57 separates grippers 52, 53 which carry the cigar. On the plate 68 is a flange 240 on which the cigar is deposited and positioned by a member 241 actuated by a rod 242 operated by i), cam 245 on a shaft 246. The plate 68 is carried by a lever 229 and reciprocated by a rocking lever 235 which engages a cam 239. The cam first moves the plate 68 downwards and a projection 232 on the lever 229 disengages a stop 233 to permit a spring 231 to move the plates 67, 68 together to clamp the cigar. When the cigar clears the bottom of the fixed plate 67 a pro. jection 2fi2 on the lever 229 engages a fixed stop 263 and separates the plates 67, 68 to discharge the re-rolled cigar on to a delivery plate 70. Before the cigar is positioned on the flange 240 its flag end is smoothed by a thimble 264, to which motion is imparted by a fork 273 on the rod 242. The rod engages in a groove 274 to rotate the thimble when it is in contact with the cigar. Trimming knives 248, 249 are operated through levers from the cam 245.
Patent GB-608829-A (GB)
Title: Improvements in or relating to digit registering arrangements and to impulse sendersemploying such registering arrangements
IPC: H04Q3/42
Filed: 1946-03-05
Abstract: 608,829. Semi-automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. March 5, 1946, No. 6799. Convention date, March 10, 1945. [Class 40 (iv)] [Also in Group XL (c)] In a keyboard sender, condensers B1 to BO (all of different capacities related to the digits 1 to 0) are normally charged to a common potential and a digit is registered by the discharge of the appropriate condenser into a further condenser such as F1. Successive digits are distributed to the condensers F1 to F0 (all of equal capacity) by a switch C stepped whenever a digit key A1 to AO falls back after operation. Transmitting numbers. Normally the gasdischarge tube T3 is fired and relays K and L are operated. Momentary operation of the start key S operates DM, stepping the wiper D to the second contact, extinguishes T3 and releases K and L. The potential on F1 prevents T3 from firing again. When both K and L fall back (L is slow to release), tubes T1 and T2 fire alternately (see Group XL (c) and operate G controlling the impulsing circuit at G1. At each impulse, condenser 3 discharges a portion of the initial charge on F 1 and when the potential on F1 falls to the critical value, T3 fires to operate K and to extinguish both T1 and T2. After an interval controlled by a condenser C and a variable resistance R, T4 fires and operates M and DM. Both T3 and T4 are extinguished, DM falls back and switch D steps on another contact to transmit the digit registered on F2. Wiper D2 completes the discharge of condenser when the registered digits have been transmitted. When the wiper D1 reaches the twelfth contact, the cam contacts DB are opened and the switch returns D1 to the fixed contact by self-interruption. Cancellation. A cancellation key E may be operated at any stage to close homing circuits for C and D. At the twelfth contact of D, cam contacts DB are opened and D does not step on to the first contact till E is restored. Transmission of special numbers. If a number of less than ten digits is transmitted, the switch D is stepped rapidly over the contacts of uncharged condensers. As L has no time to fall back between successive firings of T3, battery is not connected to the grid of T4, which accordingly follows T3 without delay. Digits can be transmitted as they are registered, without operation of S if key 1 is first pressed to fire T4 and to operate J. When a digit is registered, C2 and D3 get out of step. J releases and M (in line of S) starts the switch D. Digit transmission proceeds as before and stops when D catches up with C and operates J. The switches C, D can be homed by momentary operation of S. By operating key 2 the transmission of digits can be started automatically after the registration of a predetermined number of digits. Cam contact CB is set so as to close as the last digit of the number is registered. This contact operates DM over contact DA to start switch D and the transmission of digits.

Title: Improvements in horticultural digging tools
IPC: A01B1/02
Filed: 1959-02-27
Abstract: 884,968. Horticultural hand tools. THOMPSON, W. H. G. Feb. 29, 1960 [Feb. 27, 1959], No. 6903/59. Class 6(2). The work head of a horticultural tool such as a spade or fork is connected to the handle of the tool in such a manner that the inclination of the work head to the handle may be changed during the digging operation to decrease the amount of bending necessary by the operator. In the embodiment shown in Fig. 4, the wooden handle 1 of a spade is provided with a metal extension 2, the lower end of which is pierced by a pin 3. The pin 3 engages in slots 5 in plate-like members 6 upstanding from the blade 7 of the spade, and is formed with a transverse bore 10 for selectively engaging projections 8, 9 formed on at least-one member 6. In operation, the spade is pushed into the ground with the bore 10 engaging the projection 8, the handle 1 then being lifted to engage the bore with the projection 9, thus changing the inclination of the handle to the blade prior to lifting the soil. As shown in Fig. 6, instead of engaging a projection at the upper end of the slot 5, the pin 12 is formed with flats engaging in constrictions at the upper ends of slots 5. Also, a tension spring 17 facilitates movement of the pin 12 between its two extreme positions, and pressure on the foot pedal 16 provides further assistance in lifting the earth. In both the foregoing constructions, the sliding joint may be protected by a tube of synthetic resin material, or rubberized canvas. In the further embodiment illustrated in Figs. 7 and 9, the blade 21 has a plate-like extension 22 formed with a slot for receiving a pin 24 fixed in the tubular extension 25 of the handle 26 and in plates 27, 28 which are secured to said extension and are formed with projections 29, 31. In use, the blade is pushed into the ground when positioned as shown in Fig. 7, and the handle 26 is raised and pushed away from the operator so that the projections 31 pass above the top edge 33 of the blade. The handle is then dropped so that the projections 31 engage the real face of the blade ready for lifting the soil. As the lifted soil is thrown off the blade, the letter will resume the position shown in Fig. 7. The rearward projections 29 of the plates 27, 28 prevent the blade from swinging rearwardly relative to the handle 26.
