Title: Improvements in or relating to sheet feeding mechanisms
IPC: B65H9/08
Filed: 1951-09-03
Abstract: 716,880. Feeding sheets. BACKHOUSE, H. T. Aug. 25, 1952 [Sept. 3, 1951], No. 20794/51. Class 100 (1) Sheet-registering devices.-Sheets fed either singly or in underlapping formation over a feedboard 11 by conveyer means are prevented from over-shooting the front stops 13 by means of a suction gripper 16 which is raised through a slot in the board 11 to engage the front edge of a sheet, such as 12, and draw it down on to the board, the gripper being carried on one end of an arm 17 which is pivoted at 18 beneath the board 11 and has an extension 20 adapted to be engaged by a roller 23 on an oscillating arm 22. The downward return movement of the gripper 16 is effected by a coil spring arranged on the pivot 18, which also presses the face of the lever 17 into contact with a support block 25 on the board 11. In the raised position, the gripper 16 is connected through a passage 31 and a port 30 in the lever 17 with a port in the block 25 which communicates with a source of suction, so that the sheet 12 is gripped: as the gripper swings about the pivot 18, the port 30 moves into register with a port 29 in the block 25 which is open to atmosphere, and the sheet is re'eased. Preliminary stops 14 associated with the main front stops 13 are pivoted at 15 on the block 25, and are caused first to move upwardly and towards the advancing sheets, and then to reverse and travel back past the main stops 13 at about half the speed of the main sheet speed. This preliminary registration of each sheet is effected while the rear portion of the previous sheet (such as 38) is being removed over the top of the stops 13. The gripper 16 swings the sheet 12 forwardly as it is lowered. The degree of suction at the mouth of the gripper can be adjusted by providing two vent holes to atmosphere in the wall of the gripper, and fitting a hollow screw-threaded nipple into the mouth of the gripper, whereby these holes may be covered or uncovered, and also the effective area of the mouth of the gripper may be varied. Smoother-bars.-Pivoted bars 32 move downwardly, after the gripper 16 releases a sheet, to press the sheet against the board 11. Specifications 446,886 and 564,322 are referred to.

Filed: 1947-07-31
Abstract: 634,869. Friction shock-absorbers. MINER, Inc., W. H. July 31, 1947, No. 20874. Convention date, Dec. 24, 1943. [Class 108 (iii)] A friction shockabsorber mechanism comprises a pair of relatively slidable friction posts A, B, respectively disposed each at diametrically opposite sides of the mechanism, the posts having interengaging friction surfaces on their inner sides inclined to the longitudinal axis of the mechanism, and a coiled spring C extending lengthwise of the mechanism, and surrounding, exerting lateral inward pressure on, and having shouldered engagement with, the posts. In the construction shown, each spring abutment 12 is rigid with the corresponding post B which has flat friction surfaces 17, 18. The surface 17 is formed on a projection 15 at the extremity of the member which functions as a stop to limit compression movement by engagement with a central thickened portion 11 of the other abutment 12. The respective stops 15 interengage to limit expansion due to the spring C which is under pre-compression. The surfaces 17, 18 of the respective members B are in frictional engagement. Due to the inclination of these surfaces (which are all parallel with one another) the engaging surfaces are pressed increasingly into contact as compression movement increases. Each central thickened portion 11 is slightly eccentrically disposed in relation to the axis of the spring so that the end coil is in engagement with that side of the portion 11 which is opposite to the friction face 18 of the same abutment, whilst there is a clearance between the side and the coil at a diametrically opposite point. A strengthening rib 19 of the member B has a curved outer edge (viewed in cross-sectional plan), and is tapered in elevation to merge into the portion 11.

Abstract: 573,801. Fluid-pressure servomotors; valves. GORDON, H. H. (Chambersburg Engineering Co.). Dec. 14, 1943, No. 20919. [Classes 69 (ii) and 135] [Also in Group XXII] A hydraulicallyoperated drop hammer has a hollow ported piston - rod working over an oscillatable valve member having exhaust ports in the shape of grooves or flats, one side being parallel to the axis of the rod and the other inclined thereto to permit stroke adjustment. The tup slides in guides carried by the anvil member and cross connected at the top by a head carrying the cylinder and hydraulic gear. Ports 15 in the tubular upper end 12 of the piston-rod carrying the tup lead from the cylinder space below the piston to the exhaust ports 20 connected to a sump at 23. The valve 16 has a linkage connection at 19 to a pedal so that it may be oscillated as required. If the valve be turned to the position, relatively to the ports 15, shown at a, Fig. 8, the tup falls freely throughout its full stroke. If now the valve be turned to relative position b, pressure liquid entering the cylinder at 25 will raise the tup till the port occupies a position such as c, at which the tup will be sustained till released by a further rotation of the valve. Leakage to the interior of the piston-rod is discharged to the sump at 27 and the port 25 is supplied from the sump by a continuously running pump. A pressure relief valve providing direct discharge to the sump is provided in the supply line 25. The system is stated to be applicable for use as a servomotor.

Title: Organ stop action
IPC: G10B3/10
Filed: 1925-08-24
Abstract: 258,068. Compton, J. H. Aug. 24, 1925. Organ stop and combination actions.-A double-acting stop-head or piston with contacts, and preferably with an electric lamp indicating " on " or " off," is formed as a unit for ready insertion in the organ frame, and operates electromagnetically a separately mounted reversing device for putting into or out of operation a ventil, coupler, &c. Momentary pressure on the stop-head 1 which has a translucent face 2, against the action of the reburning- spring 5, closes a contact 7, 6 energizing a solenoid 12. In the figure, the core 11 has turned the ratchet-wheel 13 to close a contact 17, 18 and has been returned to its normal position by the spring 14. Closure of the contact 17, 18 enables the battery 15 both to operate the ventil &c. at 16, and through the terminal 10 and sleeve 9, 4 to light the lamp 3. A second pressure on the stop-head 1, by again momentarily closing the contact 7, 6 reverses the device 13 to break contact at 17, 18, thus putting out of operation the ventil and switching off the lamp illuminating the stop-face. According to the Provisional Specification, the reversing device may be operated electropneumatically; an additional contact in parallel with the stop-piston may be closed by the foot for operating the reverser alone; a number of such additional contacts may be simultaneously or successively closed operating a number of reversers; and one or more additional contacts may be similarly arranged in parallel with the reverser or reversers for the operation, in the latter case by a sforzando pedal, of the lamp and mechanism or of a number of lamps and mechanisms.
