Title: Apparatus for automatically delivering articles in batches
IPC: B23K3/08
Filed: 1932-08-26
Abstract: 406,365. Endless-chain conveyers. FARRER, J. O.. 27, Chancery Lane, London.- (Continental Can Co., Inc. ; 100, East 42nd Street, New York, U.S.A.) Aug. 26, 1932, No. 23888. [Class 78 (i).] Can bodies are delivered from a conveyer in batches first to one side and then the other, the batches being numerically determined by stepping mechanism advanced by a slide reciprocated by the bodies as they are about to leave the conveyer. The invention is described as applied to a can-making machine delivering the can bodies B by means of a conveyer 12 to a chute 50 mounted on a rockable shaft 51 and adapted to deliver the bodies to the right, or left as viewed in Fig. 10. On a shaft 76 is mounted an assemblage comprising a grooved cam wheel 78, a gear 84 and a disc 85 provided with a circular slot eccentric to the shaft. As each body B advances it is gripped by a pair of rubber rolls 65 driven by the conveyer through sprocket gearing 68 and engages the upturned end 53<a> of a slide 53 provided with a cam at its other end to reciprocate a pawl 93 driving a ratchet wheel in train with gear 84. As the slide is urged to the left, Fig. 4, by the body a pin 56 on the slide engaging an inclined slot 57 causes the slide to sink below the body, the slide then returning to normal position under spring action to await the succeeding body. The chute spindle 51 is rocked at each count by its cranked end being connected to a block 105 mounted on one limb of a vertically movable yoke 100, the other limb of which has a stud 112 engaging the eccentric slot in disc 85. As the assemblage rotates therefore the yoke is raised (or lowered), but the block 105 is restrained from following the movement by means of a pin 106 engaging one of a pair of concentric grooves in the wheel 78, connected by radial slots. When one of these slots reaches the pin the block is free to move suddenly, up or down, under the action of the compressed spring 109 or 108 and so tilt the chute in the other direction.

Abstract: 443,367. Colour kinematography. RASEK, E., 76, Mariahilferstrasse, Vienna. Aug. 20, 1934, No. 23970. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 19, 1935.] [Classes 97 (i) and 98 (ii)] Colour kinematograph negative films are produced by exposing a panchromatic film through colour filters transmitting wide bands of the spectrum so that all the negatives produced will be substantially uniform as regards density while each negative produced exhibits in black-and-white all the differently coloured details of the object photographed. The colour filter may comprise an endless band travelling with the film through the camera gate, and coloured successively redbrown, green, and blue-violet over areas the same size as the individual frames. An additional light yellow-green filter, which may travel with the film through the gate or may be fixed in the gate, may be employed, or the film or the exposure colour filter may be dyed light yellow green. A mixture of naphthol yellow, and cyanine may be used to produce the light yellow-green colour. A positive film produced by printing from the negative film is projected through a projection colour filter similar to the exposure colour filter and coloured red, light blue, and yellow-orange. The positives may also be projected in black-and-white. Reference has been directed by the Comptroller to Specifications 453/08, 11791/08, [both in Class 97], 21261/11 and 23499/11, [both in Class 97 (i)].

Abstract: 500,743. Gramophones combined with cigarette &c. boxes. DEAN'S RAG BOOK CO., Ltd., and PENNEY, J. R. Sept. 3, 1937, No. 24106. [Class 40 (ii)] A box, preferably formed for containing cigarettes or other articles, encloses a gramophone, the driving spring of which is wound by closing the lid and rotates the turntable when the lid is opened, the gramophone being characterized by the following features. The record is a disc having an endless sound groove on the under face, outside the turntable; the sound-box carries an amplifying horn, and is rockably supported below the turntable on a bracket, a spring normally rocking the soundbox upwardly so that the needle engages the sound groove. As shown, a shaft 5 on which the turntable 22 is loosely mounted carries a spring 23, the outer end of which ongages a lug 24 on the turntable. The shaft is geared through a wheel 6 with governor mechanism (not shown), and also carries a wheel 14. connected to it by a free-wheel coupling. The wheel 14 gears with a sector 16 on a shaft 15 to which one end of a driving spring 21 is attached. A-lever 17, secured to the shaft 15, is pivoted to a link 18 which is pivotally connected to the lid of the box at 19. A stop pin 20 on the shaft 15 is movable in an aperture in the frame' 4 supporting the clockwork. A small disc record 25 is secured to the turntable, and extends beyond the latter, a circular sound groove 25a being formed on the underface, or preferably on both faces, the disc being reversible. The sound-box, comprising a needle-actuated diaphragm, is secured over an aperture in the top wall of a horn 29, and the unit thus formed, shown separately in Fig. 5, is rockably supported so that the horn mouth is adjacent to an aperture 34 in the front wall of the box, and the needle 36 is held in the sound groove. The support for the combined sound-box and horn consists of a wire bracket 38, passing through lugs 37 in the sound-box, a spring 40 coiled round the bracket pressing on the sound-box so as to rock it and press the needle upwardly against the record. To prevent the needle from jumping out of the sound-groove, ridges may be formed on one or both sides of the grooves. A tray 43 is provided for receiving cigarettes &c. On closing the lid, the spring 21 is wound by movement of the parts 18, 17. When a catch 3 is released, the spring 21 unwinds, and opens the lid ; at the same time, through the gearing 16, 14 it drives the shaft 5, which by mean of the spring 23 rotates the turntable through one revolution, the drive being stopped when the lover 17 engages the frame 4 and the lug 24 on the turntable meets the stop pin 20: Sound recorded on the record is thus reproduced as the lid opens.

Abstract: 859,101. Photo-electric identifying apparatus. PATTEN CO. July 28, 1958 [Aug. 6, 1957], No. 24269/58. Class 40(3). In an apparatus for identifying an article capable of high transmission of radiations at some portions and low transmission radiations at other portions, a source of radiation is directed against the article, at least one radiation responsive cell is positioned where it is actuated by radiation transmitted through a predetermined portion only of the article and an electric circuit is connected to said cell or cells operative to associate the article with a particular class only when the radiation directed against predetermined portion or portions of the article effects said cell or cells in substantially the same way as radiation directed against corresponding portion or portions of another article known to be in the particular class. In Fig. 2 a paper currency note 53 placed on a slide tray 32 is presented to a belt feed mechanism 18 which conveys the note edgewise beneath pressure rollers 46 to a position where its leading edge engages an arm 58 of a stop switch 60 which momentarily stops an electric motor driving the belt feed mechanism 18. The note 53 is thereby positioned with respect to two groups 54, 56 of photo-cells located beneath apertures 51 in a plate 14 which supports the belts of the feed mechanism 18. A second opaque plate 48 above the belts of the feed mechanism 18 contains holes in alignment with the apertures 51 and a light source 52 directs light towards the photo-cells through the holes in the two plates 48, 14. The photo-cells 54 and the associated pairs of holes in the plates 48, 14 are located so that they are aligned with portions of poor light transmitting qualities in an acceptable note and the photo-cells 56 and the holes in the plates 48, 14 corresponding thereto are located so that they are aligned with portions of good transmitting qualities in an acceptable note. The photo-cells 54 are connected through relays 72 to normally closed switches 76 in an electric circuit and the photocells 56 are connected through relays 72 to normally open switches 78 in the same electric circuit. The electric circuit is thereby closed to place a door 62 in its note acceptance position only when all of the photo-cells 54 receive less than a predetermined amount of light and all of the photo-cells 56 receive more than a predetermined amount of light.

Abstract: 534,477. Knitting. HEMPHILL, CO. Aug. 28, 1939, No. 24680. Convention date, Jan. 20. [Class 74 (ii)] In a machine wherein wrap yarn carrying fingers arranged in separate groups are shogged to-and-fro to increase the range of the patterning, e.g. as described in Specification 460,945, the groups are so controlled that the fingers 25, 26 of one group can pass the fingers 27, 28 of the other group. A wrap yarn of one group can thus wrap the needles first at one side of a wrap yarn of the other group and thereafter at the other side of the second wrap yarn. The invention is described in connection with a rotary needle cylinder machine having wrapping mechanism as described in Specification 300,605, [Class 74 (ii)]. The fingers 25 ... 28 are mounted upon two discs 23, 24 supported upon a sleeve 29 and a spindle 35. The sleeve and spindle are each restrained from axial movement by a screw 34 and have oppositely disposed helical slots 38. A stud 44 carried by the flange of a collar 40 engages in the slots 38, and when the collar is moved axially under control of pattern mechanism, the sleeve and spindle with their discs 23, 24 are rotated in opposite directions. The slots are of such length as to permit of shogging movements of the discs to the extent of approximately 180 degrees. A pattern consisting of large diamond outlines, two of which extend completely around the tubular fabric, can thus be formed, so that it is unnecessary to have long floats extending lengthwise of the fabric.
