Title: Machine for pasting the edges of paper sheets and the like to each other
IPC: B42C9/00
Filed: 1949-05-06
Abstract: 669,651. Signature gathering. WOLFF BOOK MANUFACTURING CO., Inc., H. May 6, 1949 [May 7, 1948], No. 12109/49. Class 100 (i). [Also in Group XV] A machine for securing paper sheets or signatures together adjacent to one edge comprises means for conveying in the same direction two sheets supported on their lower edges, means for applying a strip of paste to one of the sheets close to but spaced from its lower edge and means for delivering the sheets adhered to one another. The sheets 10, 11 are fed respectively from two piles 12, 13 on to a support 21 the upright wall of which may be inclined to the vertical. Fingers 23 on an endless chain 24 engage the rear edge of the sheet 10 first to feed it past a disc 28 which applies a strip of paste thereto and then to move it forward into alignment with the sheet 11 whereupon the fingers 23 move both sheets forward together. At the aligned position the sheets are kept apart by a separator plate 39. Beyond the plate 39 are feed rolls 40, 41 rotated at a greater surface speed than the speed of the fingers 23. The sheets pass between the rolls 40, 41 in contact with one another and are delivered thereby. A circumferential recess on the roll 40 is in alignment with the line of paste and prevents spreading of the paste and also prevents smearing of the roll if a sheet 10 reaches it without a complementary sheet. The fingers 23 are held perpendicular to the chain 24 by springs which allow them to yield if, due to a fault, a number of sheets are fed simultaneously. The paste-applying disc 28 is mounted at the bottom of a paste container 29 which includes an agitator 31. The container is pivoted at 37 so that the position of the disc 28 can be adjusted in relation to the sheet 10 by a screw 38. Where the periphery of the disc 28 leaves the container, the inner end of an adjustable screw 56 co-operates with the disc to regulate the thickness of paste applied to the sheet. The disc 28 is driven at a surface speed slightly less than the speed of movement of the sheet 10.

Filed: 1931-04-24
Abstract: 372,083. Wrapping-machines. FORGROVE MACHINERY CO., Ltd., GROVER, F., Oakhurst Avenue, Dewsbury Road, Leeds, and MACKINTOSH & SONS, Ltd., J., Albion Mills, Halifax, Yorkshire. April 24, 1931, Nos. 12163 and 25391. [Class 94 (i).] Tablets, which are to be fed to a wrapping- machine, are placed on an inclined tray which is subjected to controlled vibration so that the tablets slide into a convenient position for removal by an operator to the conveyer band of a wrapping machine. Trays bearing the tablets are placed on a frame a and held in position by supports a<1> . . a<4> at the angle of friction so that, unless the frame is vibrated, the tablets will not move. The frame is pivoted at d to a bracket on the machine, and rests on rollers a<10>, a<11>, a<12> adapted to traverse surfaces e<1>, e<2>, e<3>, when the frame is oscillated about its pivot. To produce the oscillation, a bell-crank lever g<1>, g<3> is engaged in a slot g by a crank f in a driving shaft f<2>. A slot g<4> in the other arm of the lever is engaged by a spindle h<1> and transmits the oscillatory movement through gearing h<1> .. h<6> to the frame. The amplitude of the oscillation is controlled by a pedal i<4> by depressing which the spindle h<1> can be raised to any position in the slot g<4>. When the pedal is released, the spindle sinks to the bottom of the slot and is then coaxial with the pin g<2> and no oscillation is transmitted. In use, the frame is oscillated to cause a supply of tablets to elide off the tray, over a plate j and on to a table k from which the operator removes them and places them on the wrapping- machine feed belt c. The tray may be open at one end, or may have a lower inclined guiding wall to moderate the feed.

Filed: 1948-05-04
Abstract: 653,017. Concrete piles, construction and driving. WAAL, J. A. De. May 4, 1948. No. 12210. [Class 68(ii)] Hollow concrete piles which are divided into longitudinal sections are driven by first driving one section 11<SP>1</SP> then centering the following section 11 on the driven section by means of a short loose coupling tube 10 fitting into the interior of the two sections, the pile-driving blows being struck within the integral foot of the lowest section simultaneously with the pressing down of the whole pile by means of a force exerted on the top end of the upper section. The driving apparatus consists of a platform 1 movable along rails, a scaffold 2 pivoted at the base, a winch 3 at the rear, and a ballast block (not shown) coupled to the front and movable along rails. A drawing cap 7 is suspended by pulley blocks from the beam 4, and has pulley blocks 8 on the underside. Cables pass over the blocks 8 and blocks on the platform to the winch 3. The cap 7 is placed over the coupling tube 10 of a pile section 11 which is similarly coupled at its base to a driven section 11<SP>1</SP>, and presses the pile into the ground. A cable 14 from the winch passes over a pulley at the top of the scaffold and carries a pile driver 15. The base hollow concrete pile section (Fig. 3) has a striking bottom 16 reinforced by a tube 17 and cushioned by a wooden buffer 18, which may have a semi-spherical shape to fit a similar shape in the striking bottom. The pile driver may also have a semi-spherical end. The foot may be reinforced by a thickened concrete portion which also increases the carrying capacity of the pile. The bore of the pile may have any required shape. The driving blows may be applied to a striking ring or to a plurality of striking cams in the foot. The coupling tubes 10 act as guides for the pile driver 15.

Title: Improvements in electric circuit breakers
IPC: H01H33/98
Filed: 1934-04-23
Abstract: 429,401. Liquid - break switches. COATES, W. A., Walford Lodge, Dunham Road, Bowdon, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. April 23, 1934, No. 12222. [Class 38 (v)] Relates to circuitbreakers of the kind in which one of two seriesconnected breaks occurs in a reservoir chamber 3 between a fixed contact and an auxiliary moving contact 10, and the pressure so produced causes insulating liquid (such as oil) to flow from the chamber 3 through one or more ducts 4 to the other arc in a chamber or pot separated from 3 by a perforated partition 6<a> or alternatively to cross passages 5 in an insulating member 6 associated with 3, in a longitudinal channel 9<a> through which member 6 the other arc is formed between the auxiliary and main moving contacts 10, 1, the auxiliary moving contact 10 forming a closure between 3 and either the perforation 9 or the channel 9<a> to ensure that, on opening the contacts, the liquid traverses the ducts 4. Consists in that the closure 10 closes by gravity and a spring contact finger 14 is so located in 3 as to be deflected by 10 only when the latter is moved by the entry of 1 to close the circuit, and when 1 is withdrawn to open the circuit, the finger 14 gives the closure 10 an initial urge to the closed position, so causing an initial arc to strike between the tip 15 of the finger 14 and the closure 10, which remains in contact with 1 until the latter leaves the chamber 3 and draws the second arc in the channel 9<a>. The closure 10 shown is a flap hinged at 11, but may be a ball in a recess, Fig. 2 (not shown). Where the duct 4 leads to another chamber, the partitions 7 are removed and the chamber is closed as shown by the dotted lines, the exhaust being through the orifice 8. Contacts.-The closure is formed of non- arcing metal such as a tungsten-copper mixture.

Title: Improvements in and relating to horse collar caps
IPC: B68B3/04
Filed: 1925-05-11
Abstract: 243,985. Brown, M. R. May 11, 1925. Shaping.-Relates to horse collar caps or pads made by moulding leather under high pressure so as to render it very hard and stiff. In order to facilitate riveting the cap to the collar, the cap is, according to the invention, so formed that a certain portion or portions of the leather are left uncompressed and relatively soft, the rivets being inserted through such portions. Figs. 1 and 2 show a cap 1 in which a portion 5 of rectangular outlina is softer than the remainder, the rivets 6 by which the cap is secured to the flap of the collar being passed through the part 5. The heads of the rivets on the underside of the cap, which contacts with the horse's neck, are flush with the surface of the uncompressed leather portion. Moulding-dies for shaping the cap and at the same time leaving the part 5 relatively soft are shown in Figs. 5 and 6. For this purpose a suitably shaped recess 17 is provided in the moulding face of the die member 13. Instead of leaving a single portion of the leather soft, isolated portions for receiving separate rivets may be so formed. A further modification of the process consists in forming a recess in one of the moulding die members and a corresponding projection in the co-operating member, so that the effect shown in Fig. 4 is produced, 11 being the relatively soft portion, which projects upwards slightly.
