Patent GB-373804-A (GB)
Title: Improvements in or relating to adhesive-applying mechanism in signature-handling machines
IPC: B42B2/02
Filed: 1931-06-18
Abstract: 373,804. Bookbinding-machines. POLLAK, J. E., 20, Holborn, London.-(Brehmer Geb. ; Plagwitz, Leipsic, Germany.) June 18, 1931, No. 17748. [Class 16.] In bookbinding-machines having a pivoted sheet or signature carrier, means are provided for pasting the signature intermediate between the feeding position and the stitching position ; the pasting-device, including a pasting-member and an adhesive container, is located between the stitching-devices and the automatic sheetfeeding means, and the pasting-member is first moved into the path of the carrier to make contact with the sheet, then moves with it for a short distance without relative movement and finally is withdrawn from contact with the sheet and out of the path of the carrier. Means are also provided to make the device inoperative except for certain selected signatures. The signature S is fed by rollers 19 and bands 18 to a carrier 12 on an arm 11 pivoted on the machine frame 10, and is carried in an arcuate path to a book pad P, where it is stitched by a head 15. A pasting-roller 25 is mounted in arms 26 pivoted to levers 27 mounted on the side frame 20. The levers 27 are oscillated through a chain of levers 29 .. 32, from a cam 32b on the driving-shaft 16, so that when the roller 25 lies in the path of the signature it moves with a vertical velocity equal to that of the signature. At the upper end of its path the roller 25 takes paste from a roller 24 in a paste-tank 23. The horizontal movement of the pasting-roller 25 is controlled by a roller 35a mounted on levers 35 and running on a cam 34, which is of such a shape that, during the period in which the roller 25 is in the path of the signature it would first travel with a slightly less velocity than the signature and is then accelerated as it is lifted out of the path so that there is no smearing. The signatures to be pasted are selected by a cam-follower 37a running on the edge of a cam 37 on the shaft 16, and operating a pawl 41a through linkage 38 .. 41. The pawl 41a rotates a ratchet wheel 42, which may be interchangeable, so that the wheel 42 makes one complete revolution for the appropriate number of cycles of operation of the carrier. A roller 44, mounted on the shaft 43 of the ratchet wheel 42, rolls in an aperture in the strap end of a slide bar 46, which is connected by a lever 45 to the stub shaft 31a of the lever 32 so that movement of the slide bar will 46 lift the follower 32a from the edge of the cam and render it inoperative. A projection 46a on the bar 46 abuts on the raised edge 42a of the ratchet wheel, and once in every revolution of the ratchet wheel slips through a notch in it, drawn by a spring 43a. Then, during one revolution of the cam 32b, the pasting-device operates, but the lifting of the projection 46a out of the notch by the consequent movement of the bar 46, and its subsequent detention by the raised edge 42a, prevent operation during subsequent cycles. Specification 372,427, [Group VII], is referred to.

Filed: 1953-06-29
Abstract: 735,813. Travelling-band filters. DELPARK CORPORATION. June 29, 1953, No. 17978/53. Class 46. [Also in Group XXX] The device includes driving mechanism such as 22 to 25 for periodically moving an expendable filter medium such as paper 21 drawn from a roll 13 on a perforated conveyer band 14, 15 over a tank 10 for receiving filtered liquid, lifting elements such as side aprons 20 and end ramps 29 (not shown) and over which the conveyerband rides for causing it to sag within the tank to form a liquid-receiving pocket, and a control member comprising a float 38 positioned in the pocket and governed by the accumulated supply of residue therein to actuate the driving mechanism to move a fresh section of the medium into the pocket. Material to be filtered, such as used machine-tool coolant, is discharged from a pipe 26 through a slot 28, some filtration taking place through the medium and conveyer band above the ramp 29, the central portion of which is open. The level of sludge on the medium 21 is in part controlled by a baffle plate 31 pivotally mounted above the central tank pocket just beyond the down-turned end portion of the ramp 29. When the liquid level reaches a predetermined height the float 38 rises and the float arm 39 thereupon operates a switch 35 controlling the power supply 37 to the motor 22. The motor on being energized drives a roller 16 through gearing 23 to 25, the roller in turn moving the conveyer band so that its upper portion moves from left to right through the tank, withdrawing filter paper from the roll 13 and discharging it from the other end of the tank as it does so. Passage of the paper 21 up the ramp 40 ensures final drainage and filtration. The conveyer band preferably comprises an endless slatted belt 14 having flexible perforate side skirts 15.
