Title: Improvements in combined coinfreed weighing and delivery machines
IPC: G07F17/04
Filed: 1931-12-17
Abstract: 389,206. Combined coin-freed weighing and delivery apparatus. PEARSE, W., 212, Brighton Road, Purley, Surrey. Dec. 17, 1931, No. 34942. [Class 27.] In a combined coin-freed weighing and articledelivery machine, a coin retained in the weighing-apparatus can be released by displacement of a hand-actuated device to pass to the releasing mechanism of the delivery apparatus, so permitting an article to be delivered without requiring a person to mount on or descend from the weighing platform. The invention is described as applied to the well-known coin-freed weighing-apparatus described in Specification 13260/89, [Class 27, Coinfreed apparatus &c.], in which a counterweigh t e d pointer actuating lever j, Fig. 2, bearing a coin-bucket j<2> is tilted by the coin which is discharged, on the return of the weighing mechanism to zero, by a lever n<1> on the bucket j<2> wiping over a rack of pins o to open the bottom n of the bucket. According to the invention, the rack of pins o is slidably mounted by pins and slots o<3>, o<2> and connected by a link r<3> to a lever arm r<2> operated by an outside handle r. If the weighing-mechanism is not used, the rack can be displaced against the action of a spring o<4> by operating the handle r to discharge the coin from the bucket j<2>, the coin dropping to a shoot p leading to the releasing mechanism of the article delivery drawer. The rack may be connected to the delivery drawer f, Fig. 3, so that an initial free movement of the latter will draw the rack downwards. The drawer has a rearwardly extending rod s with an abutment s<4> for operating a lever x connected by a rod r<3> to the rack o. After the initial movement sufficient to actuate the lever x, further movement of the drawer is prevented by a catch u engaging a shoulder s<1> on the rod s, unless a coin is received in a slot s<2> of the rod. This coin is drawn over a rack t and pushes a slide v having an incline v<1> on its front end to raise the catch u out of the path of the shoulder s<1>.

Abstract: 208,018. Schieren, G. A. Dec. 23, 1922. Razors, safety. Relates to safety razors of the type in which a scale or index is provided to facilitate re-setting a flexible blade the cutting edges of which are adjustable towards or away from the guard member by rotation of the handle, and comprises an arrangement in which a clamping plate with a threaded stem, passing through a blade and guard, engages a threaded socket in the end of the handle and an index member on or in connection with the guard co-operates with an index sleeve rotatable on the handle but retained in set position thereon by resilient friction means. As shown in Fig. 2, the threaded stem on the clamping plate 5 engages the end of the handle 1 which bears directly against the guard 4. An index member 9 is provided on the guard for use in conjunction with an index or scale sleeve 11 which is rotatably mounted on a reduced portion of the handle 1 being retained in adjusted position thereon by a spring 14 in a recess 13, Fig. 4. In the modification shown in Fig. 6, the guard member 4 is formed with a stem 1<a>, through which passes an elongated stem 6a on the clamping plate 5<1>, the end thereof being threaded to engage the hollow threaded end of a shortened handle portion H. The index sleeve 11<a> is mounted on the handle portion H as before, being retained by a collar C on the end of the handle, and co-operates with a single index mark 9<a> on the extension 1<a> of the guard. In re-assembling, when tho handle has been brought to the position of initial frictional contact with the lower surface of the guard, the index sleeve 11 is rotated independently to bring the zero mark thereon opposite to the fixed index 9. For final adjustment, the handle is then turned, carrying the index sleeve with it, until the desired index mark on the sleeve, ascertained by previous experiment, coincides with the index pointer on the guard.

Title: Machine having axial pistons
IPC: F16H1/32
Filed: 1973-07-24
Abstract: 1444805 Swash-plate engines and compressors M BRILLE 24 July 1973 [25 July 1972 6 June 1973] 35232/73 Headings F1B F1M F1N and F1S An axial piston compressor or hot-air, steam or two or four stroke I.C. engine comprises an input or output rotary shaft 9 having an inclined crank 8 which pivotably receives the pin 7 of a swash-plate 5, 6, pistons (not shown) each connected by a rod 48 to a respective arm 47 on the. swash-plate, and a pair of frusto-conical surfaces 12, 17 on the swash-plate disposed to roll on respective frusto-conical surfaces 14, 19, fixed to a frame 33. The co-operation between the frusto-conical surfaces causes the axis yy' of the swash-plate to move through a conical path having an apex S. Bevel gears 11, 16 concentric with the frusto-conical surfaces 12, 17 mesh with respective bevel gears 13, 18 concentric with the frusto-conical surfaces 14, 19 to prevent slipping between the frusto-conical surfaces. The positions of each surface and its bevel gear may be reversed. The assembly comprising the shaft 9, swash-plate 5, 6 and gears 13, 18 with frusto-conical surfaces 14, 19 is capable of axial movement whereby the fixed stroke of the pistons is shifted axially to vary the compression ratio of the machine. The axial movement of the assembly occurs automatically as the load on the pistons changes. Thus with increasing piston load, the columns 2, 4 carrying the frusto-conical surfaces 12, 19 move to compress a spring 37 in the form of a stack of Belville washers and thereby decrease the compression ratio. The mean value of the compression ratio is determined by a flanged member 38 screwed into the frame 33 so as to vary the degree of compression of the spring 37. Rotation of the member 38 is effected via a shaft 42 having a pinion 41 meshing with a gear 40 on the member 38. To damp the action of the spring 37 liquid is supplied through an inlet 67 to the chamber containing the spring, the liquid discharging at a controlled rate through calibrated orifices 68. The shaft 9 carries a flywheel 62 and a pinion 54 which meshes with a pinion 55 having a shaft 56 for driving, via a gear 57, an oil or fuel pump or ignition distributer (not shown). The shaft 56 passes between the arms 47 and is provided with cams 58 for operating engine valves (not shown) and a gear 60 having a flywheel 63 and a rotor 66 for distributing fuel/air mixture to the engine cylinders. A joint having frusto-conical surfaces and for connecting the piston-rods to the swash-plate is disclosed in Figs. 7 & 9 (not shown). The necessary geometric configuration of the machine parts is described.
