Title: Device for inserting wire coils in tapped holes
IPC: B25B27/14
Filed: 1943-05-07
Abstract: 565,418. Inserting helices in tapped holes. AIRCRAFT SCREW PRODUCTS CO., Inc. May 7, 1943, No. 7255. Convention date, June 16, 1942. [Class 83 (iii)] Wire helices are inserted into tapped holes, e.g. to provide a wear resistant thread in soft material, such as wood, aluminium, or artificial material by contracting the diameter of the helix during insertion and then releasing the helix to permit it to spring into place. The helix, formed initially oversize, may have the leading end 11, Fig. 2, slightly reduced in diameter and provided with a tang 13. The inserting tool is in two main parts 14, 18. The part 25 of the sleeve member 18 is formed of a diameter at 26 to receive the uncontracted helix 10 and it is considerably cut away at 27 to permit lateral insertion of the helix. The front part 22 has a thread 23 of the diameter, or somewhat less than the diameter, of the tapped hole in which the helix is to be screwed. The mandrel 14, which has a tapered and slotted end 15, is then advanced through the helix to engage the tang in the slot and by means of the end 17 shaped for holding a driving and the knurled part 19 of the sleeve, the parts are relatively rotated further to coil the helix on the reduced diameter of the mandrel, leaving a part of a turn still engaged in the threaded end 22 to hold the helix contracted. The parts 14, 18 are then locked against reverse rotation by a screw 28 pressing on the mandrel through a fibre pad. Whilst so held the helix is screwed into the tapped hole to be lined and finally further movement of the mandrel relatively to the sleeve releases the helix and allows it to expand and seat itself firmly in the hole. Reverse rotation of the mandrel then removes the tang. In modifications, the rear end of the sleeve member is reduced in diameter, split and provided with a taper thread for a clamping nut to close this part of the sleeve on the mandrel. The helix-engaging end of the .sleeve tapers from the initial size of the helix to the contracted size. The helix then need not have a leading end 11 of reduced diameter.

Abstract: 678,958. Tobacco pipes. ARNOLD, E. G. March 19, 1951 [March 23, 1950], No. 7303/50. Class 130. A tobacco pipe has a ball joint connection between the mouthpiece and stem which allows the stem to be set in different angular positions relative to the mouthpiece and maintains the stem in the adjusted positions when so set. As described, applied to a briar pipe of the kind having the stem and mouthpiece joined by a cylindrical metal mount with an in-turned flange at the mouthpiece end, the mount acts as the outer casing of the ball joint and, before screw or push assembly on the stem or insertion within a recess therein, receives through its wide end (a) a ball of similar metal having a screwed extension which projects through the narrow end of the mount for attachment to the mouthpiece by threaded engagement with a bore therein, (b) a rubber washer and (c) a holding washer slotted to receive a screwdriver head and externally threaded to screw into the mount by co-action with threads therein. A smoke passage passes through the ball and extension, and is countersunk at the ball end to allow a free draught in any joint position. The mouthpiece end adjacent the mount is concave so as to move with clearance about the mount end. The mount may be of silver, duralumin or, according to the Provisional Specification, gold.

Title: Apparatus for feeding cards to punching members in a card punching apparatus
IPC: B65H3/24
Filed: 1958-03-10
Abstract: 839,154. Feeding sheets. KIENZLE APPARATE G.m.b.H. March 10, 1958 [Sept. 9, 1957 (2)], No. 7584/58. Class 117 [Also in Group XVI] Cards 2 are separated sequentially from the bottom of a container 1 by a reciprocating slider 4 having an upstanding knife edge 3, and fed between feed rollers 15, 16 which forward them between guides 25 in a cardpunching machine, the slider 4 and feed roller 15 being driven from the same shaft 12 such that the speed imparted to the cards by the slider is equal to or slightly greater than the peripheral speed of the roller. The slider 4 is carried on rocking levers 7, 8, and the pivot pin 9 of the latter is rocked by a lever 10 engaging a cam 13 secured on the drive shaft 12 which imparts a slow return movement, and a high forward movement, to the slider 4. After the card is punched, it is forwarded by a second set of rollers 21, 22. The shafts 12, 23 of the rollers 15, 21 are driven through gears 19, 20 and slipping clutches from a motor 18. While the card is passing through the guide 25 it is stopped periodically by known means connected to the gear 20. To ensure perfect registration of a card at the punching position in the guides 25, the roller 15 has an inclined recess 26 terminated by an abutment wall 27 in its periphery: the card enters the recess 26 as it emerges from the container 1, abuts the wall 27, and is then fed forward to the punching station. Similarly, as the card emerges from the punching station, it enters a similar recess 26 in the roller 21, and abuts a wall 27 therein. Pile tables; weighting arrangements:- A lid 43, Fig: 3, resting on the pile of cards 2 is pivoted unsymmetrically at 44 to a double-linked lever 45, 46 which is fixed on a pivot pin 47, and torque is applied to the pin 47 by a lever 48 provided with a weight 49, said torque increasing as the pile of cards diminishes. The lid 43 is lifted and tilted to allow cards to be inserted into the container 1 by the action of a slotted lever 54 on a pin 55 secured to the lever 46, the lever 54 being pulled upwardly when a side 50 of the container is hinged about its pivot 51. Safety devices:-When there are no cards left in the container a switch arm 57, Fig. 3, which normally presses against the bottom card, rises to open a switch 56 in the circuit of the driving motor of the punching device, or to operate a warning. A switch arm is also urged towards each feed roller 15, 21 to rest on a card, and each associated switch is opened, if a card is absent at predetermined periods of the card feeding cycle, due to the extra movement of the switch arms: cams rotating with the rollers 15, 21 maintain the switches closed during the intermittent periods in a normal feeding cycle when a card is not in position on a roller 15, 21.

Title: Improvements relating to the moulding of concrete and like blocks
IPC: B28B1/04
Filed: 1926-03-19
Abstract: 274,537. Hanssens, A. March 19, 1926. Tamping - machines. - A machine for moulding concrete blocks &c. is provided with a tamper 1 supported above a mould 7 and actuated by a rotary operating device from a control shaft 16 through the medium of a two-way clutch 32 which is shifted automatically by means actuated by the tamper when the material in the mould has been compressed to the pre-determined extent, the control shaft being disengaged from the rotary device and engaged with the mould-raising mechanism. The tamper 1 is fixed to uprights 2 sliding in arms 3 on a frame 4, Fig. 1, and is adapted to be lifted by a band 9, which is secured to a shaft 11 moving in curved guides 13. A clutch 32 slidable on a shaft 16 is adapted to engage either of a pair of toothed wheels 37, 40 loose on the shaft 16 as shown in Fig. 4, and when the clutch engages the wheel 40 motion is imparted through suitable gearing to a pulley wheel 24 loose on a shaft 15. The pulley wheel 24 carries a pivoted spring-controlled spur 23 which is adapted to engage the shaft 11, and thereby lift the tamper. The ends of the guides 13 are curved so that after moving a certain distance the shaft 11 is released and the tamper is caused to fall. Such operation continues automatically until a member 8 on the uprights 2 engages the end of a counterweighted lever 29, Fig. 1, pivoted at 30. The pivoted clutch 32 carries an arm 31, and is retained normally in engagement with the toothed wheel 37 by means of a spring 36, Fig. 4, and when in such engagement the shaft 15 is caused to revolve through the engagement of gear wheels 37, 20, and cables 19, Fig. 3, connected to the mould box 1 are wound on grooved wheels 18, and the mould box is thereby raised. The mould box 7 has sleeves 44 sliding on uprights 45. In operation, the clutch is caused to engage the wheel 40 and the tamper 1 then operates automatically until the member 8, which has been positioned according to the extent of compression desired, moves the lever 29 so as to allow passage of the clutch arm 31 under the influence of the spring 36. The tamping operation then stops, and the clutch engages with the wheel 37 to cause the mould to be lifted, the tamper being prevented from rising by the engagement of a spring-controlled lever 46, Fig. 2, with the member 8. When the mould is lifted clear of the moulded block, a member 35 on the mould releases the lever 46 through the medium of an arm 50 and the tamper is lifted by the mould until it engages a hook 27. The member 35, during its upward movement, also engages a roller carried by a lower arm 31 on the clutch, and carries the latter into neutral position. A braking device is provided to lock the mould in its upper position.

March 12, 1935, No. 7696. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 13, 1935]. [Class 97 (i)] In the simultaneous projection of colourrecord images, each image is projected both by unfiltered light and by light appropriately filtered ; such projection may be effected in apparatus comprising two lenses, a two-picture gate, and intermittent mechanism feeding one image at a time or two images at a time. Fig. 8 shows a projector having a twopicture gate 4, two lenses 8, 9, and an intermittent sprocket 7. The sprocket 7 is of twice the normal circumference, and is rotated at half the normal frequency, when two images are fed simultaneously ; it may be of normal size and rotation frequency for feeding one image at a time, each image being projected twice. The gate may have separate aperture plates 34, 35, Fig. 10, respectively vertically and laterally adjustable by screws 36, 40 engaging slots. The upper and lower lenses 8, 9 may be respectively vertically and horizontally adjustable in slides 14, 19, Fig. 9, by screws 16, 21 and may be simultaneously focused by turning a head 28 on a shaft 27 carrying a pinion 26, engaging a rack 25 on a slide 22. The lens axes are parallel and their separation may be adjusted to less than the image pitch to produce superposition on the screen. The projector may be used without colour filters to project monochrome images with increased appearance of depth, or with colour filters for the projection of colour-record images. If two images are fed simultaneously three filters 45, 46, 47, Fig. 8, may be mounted in a vertically adjustable frame, the filters 45, 47 being of the same colour, and the filter 46 of the complementary colour. The frame may be adjusted so that either the filters 45, 46 or the filters 46, 47 are before the lenses. If the images are fed singly, the filters may be carried by a rotary disc having filters 50, 52, Fig. 12, of one colour, filters 51, 53 of the complementary colour, and opaque sectors 55, 56. Such a disc may be used in conjunction with the usual shutter on a shaft 57. Fig. 4 shows fixed filters comprising an orange-red filter 11<1> and a red filter 12<1> used together for one image, and a green filter 10<1> used for the other image. Unfiltered light may be included in the projection beams by the provision of an aperture 20 in all the filters, by the provision of a similar aperture in one of the filters separately, or by adjustment of the positions of the filters to permit unfiltered light to pass their edges.
