Title: Improvements in the construction of accordions
IPC: G10D11/02
Filed: 1938-01-28
Abstract: 514,100. Accordions. RAZZABONI, U. Jan. 28, 1938, No. 2815. Convention date, Feb. 1, 1937. [Class 88 (ii)] An accordion having notes which are each composed of the vibrations of a pure voice reed and a number of vibration reeds tuned to a slightly different frequency, has the pure voice reed of each note isolated and controlled by a separate valve which may be actuated alone or together with the valve or valves controlling the vibration reeds. Alternatively the isolated reed may be controlled by a separate alternative valve actuated independently of a main valve operating both the pure voice and vibration reeds. The pure voice reed of any note may then be played simultaneously with the octave note above or below it by the use of appropriate coupling devices. Means for silencing the vibration reeds or the pure voice reeds are provided. Fig. 1 shows part of a valve board in which main valves 2 control ports 6, 7 for the vibration reeds and ports 5 for the pure voice reeds, separate valves 3 controlling other ports 4 associated with the pure voice reeds when they serve as the octaves for upper or lower notes: The valves 2 are actuated by key levers 8 and the valves 3 by levers 9 coupled by cables passing through a tube 11. A slide 13 enables the ports 4 to be closed, and a slide 14 enables the ports 6, 7 to be closed when required. Alternatively clutch devices in the connections may de-couple the levers 8, 9 when the octave is not to be played. The valve 3 further may be seated on the back of the valve 2 alternatively to control the same port. Fig. 10 shows a valve 2 controlling a pure voice reed and valves 34 controlling vibration reeds, respectively connected by cables 33 to two pivoted levers 22 engaged by the end of a key lever 28. The end of the lever comprises two slidable parts 24, 25, Fig. 9, side by side and independently movable by members 30. The part 24 engages one or both of the levers 22 according to its position in. its slide 29 and the part 25 similarly engages levers 23 connected to the valves of an octave note. Figs. 14 and 16 show valves actuated by rods 40 having ends 42 which are selectively moved into the path of key ends 41 by cams 44, cables 45, 46 effecting octave coupling. Alternatively actuation of the valves may be effected by cables passing over adjustable combs or slotted plates to render them selectively slack or tight. In another modification rods moved axially by the keys can be rotated by a register to bring pins on the rods selectively into operative engagement with the valves. According to the Specification as open to inspection under Sect. 91, the keyboard of the instrument may be made foldable on to the body. This subject-matter does not appear in the Specification as accepted.

Filed: 1927-02-01
Abstract: 272,415. Willis, R. C. Feb. 1, 1927. Drilling-machines; portable turning-apparatus, -In a method of and apparatus for reseating valves, the reseating-tool is set in a position perpendicular to the valve-stem guide and locked there so that the cutting operation may be performed without further dependence on the valve guide. The apparatus comprises an arm 7 slotted longitudinally at 8 to receive a securing bolt 9 and having a head 13 in which a bearing 15 for the cutter arbor 2 is mounted. The arm rests on a base-block 1 attached to an internal combustion engine cylinder-block 5 by bolts or studs 4 and carrying the bolt 9 on which is mounted a bridge 10 forced into engagement with the arm by a nut 1 hand operated at 12. The head 13 is provided with an internal spherical recess 18 lined with soft metal such a babbit metal for receiving the spherical end 17 of the bearing 15, the head being split at 14 and provided with a handle and nut 20 for clamping the bearing in any adjusted angular position. In operation, a pilot 25 on the cutter arbor is adjusted centrally in the valve guide 26 and the nut 11 and handle 20 are then locked and the arbor withdrawn so that the cutter 24 may be mounted therein. The cutter is rotated to perform the reseating operation by a hand or power operated attachment 28. For trueing up the valve-stem guide a cutter 32, Fig. 4, carried by an arbor 31 is used in place of the cutter 24 and is adjusted in the same manner if the axis of the guide is inclined to the cylinder axis. When the guide axis is perpendicular to the face of the cylinder block 5, the cutter axis is adjusted by means of a sleeve 29, Fig. 1, which fits the bearing 15 accurately and which has a face 30 perpendicular to its bore for engaging the arm 7. When an entirely new seat has to be fitted the aperture for its reception is formed by a right angle cutter substituted for the cutter 24.
Patent GB-413037-A (GB)
Title: Improvements in or relating to yarn-winding machines
IPC: B65H59/38
Filed: 1933-01-30
Abstract: 413,037. Variable - speed drive for yarn winding machines. LEEDHAM, L. H., and WILDT & CO., Ltd., Adelaide Works, Leicester. Jan. 30, 1933, No. 2894. [Class 120 (ii).] In a machine for winding yarn on to a bobbin having a variable speed drive, are provided a relatively slow speed starting drive taking the spindle to a speed comparable with the slowest speed of the variable speed drive, and change-over means for coupling the spindle with either drive at will. The spindle-driving shaft 19, Figs. 1 & 2, which is reciprocated endwise carries a friction wheel 21 giving the variable speed drive through a wheel 22 splined on the spindle 11, and a friction wheel 20 of width sufficient to allow engagement at any position of the reciprocation with a friction wheel 24 giving the starting drive. The wheel 24 rotates on a stud 25 on an arm 26 pivoted at 27 to an arm 28 of a bell-crank lever 28, 29 pivoted on a pin 30 and having an extension 31 sildably mounting a handle 32, slotted to engage the pin 30 and a pin 33 on the extension 31. The handle 32 is normally drawn towards the pin 30 by a spring 34 and is notched to engage a pin 38, the wheel 24 being thus raised clear of the wheel 20 and holding the wheel 22 against the pressure of a spring 39, clear of the wheel 21, turning of the arm 26 being limited in one direction by a setscrew 41, &c., the spindle 11 being at rest. To start the spindle 11, the handle 32 is pulled outwardly, releasing it from the pin 38, and turned anti-clockwise about its pivot 30 to lower the wheel 24 into engagement with the wheel 20, further turning being limited by engagement of the end of the arm 29 with a detent 46 on a lever 44, which is released against the action of a spring 47 by a cam 49 rotated synchronously with cam controlling the reciprocation of the shaft 19 and of the yarn guide. When the latter are in positions corresponding to the slowest . speed of the variable drive, and the lowest position of the yarn guide, the release occurs, and a strong spring 51 turns the bell-crank lever further, causing the wheel 22 to be lowered on to the driving surface of the wheel 21, and the wheel 24 to travel partly round the periphery of the wheel 20 and out of contact with the wheel 22. To stop the spindle, the handle 32 is moved back to its original position. The point of contact, and angle of drive of the wheel 24 on the wheel 22 is such that slip occurs on starting ; this effect may be enhanced by driving the wheel 20 from the shaft 19 through a friction collar, or alternatively through a tension spring 58, Fig. 7, the extension of which is limited by a projection 60 and a stop 61.
