Title: Counter-balanced fixed stroke piston machines
IPC: F16F15/26
Filed: 1974-04-29
Abstract: 1471447 Balancing: compressors A BRAUN 29 April 1974 [30 April 1973 (2)] 18695/74 Heading F1M and F1N To counterbalance the reciprocating parts of a fixed stroke reciprocating piston machine, a piston is connected to or forms part of a first or second member both of which reciprocate along the longitudinal axis of the associated cylinder and the two members are inter-connected by either racks and pinions or pivoted levers so that their movements are 180 degrees out of phase. The first member is connected by a connecting rod to the crank of a crank-shaft which has a counterbalancing portion for counterbalancing at least the crank. The machine may be an engine but the described embodiments are compressors. In a first embodiment Fig. 5 a compressor has two pistons 124, 132 inter-connected by parts 133, 138, 139 and the piston 124 is connected to a crank-shaft 72 having a balancing portion 75 by a rod 67. A second counterbalancing member 141 moves oppositely to the pistons 124, 132 by being connected to the part 133 by outer and inner racks 48, 49 and 134, 136 of a mechanism 141 engaging two pinions 34, 36 which are mounted on stationary shafts. The outer racks 48, 49 are interconnected together by a pair of plates 51, (52) having slots through which the pinions' shafts extend to permit reciprocation of the plates 51 (52). Inlet and outlet, valves 127, 142 and 128, 143 are located at the outer ends of cylinders 122 and 129. In an alternative but similar arrangement (not shown) a shaft extends upwardly from a piston and carries a mechanism similar to 141 at its upper end. The piston divides the cylinder into upper and lower compression chambers and the outlet of the upper chamber is connected to the inlet of the lower chamber via an intercooler to provide two stage compression. Another two stage compressor Fig. 7 has a first piston 216 connected to a part 258 and a second piston 214 connected by a shaft 229 and a similar rack and pinion mechanism to 141 to the first piston 216. A crank-shaft 272 is driven by an electric motor 277 and the outlet valve 221 of a first stage compression chamber 217 is connected via an intercooler 226 to the inlet 222 of a second stage compressor chamber 218. The piston 216 maybe replaced in another alternative construction by a wall extending across the cylinder to define with the lower face of piston 214 a first stage compression chamber. Furthermore a second wall maybe spaced below this wall to define an intermediate, ventilated chamber which prevents lubricant or fumes from passing into the compression chambers from the lower parts of the compressor. As an alternative to the racks and pinions shown in Fig. 7 the piston 216 maybe connected to the shaft 229 by a pair of intermediately pivoted levers 301, 302 Fig. 11 whose inner and outer ends are connected by pins and links to the shaft 229 and piston 216 respectively.

Title: Improvements in or relating to work-locating stop mechanism for automatic lathes
IPC: B23B13/12
Filed: 1950-07-27
Abstract: 685,159. Lathe details. ARON, E., and PULMAN, W. E. R. April 30, 1951, No. 18827/50. Class 83 (iii). Mechanism for operating a bar-stock stop for automatic lathes comprises a stop movable into and out of operative position in the path of feed of the work and adjustable actuating means operated in timed relationship with the work feed whereby a stop may be moved once for each feed of the work or for alternate feeds or after any predetermined number of feeds of the work, according to the adjustment of said adjustable means. The stock stop 12, Fig. 2, is carried by a spindle 13 pivoted in the lathe headstock and is rocked by a lever 15 and link 16. Near the lower end of the latter a further lever 17, Fig. 1, is pivoted at 19, this lever being pivoted to the machine at 18 and carry ing a roller 20 pressed into engagement with a cam 5 on a shaft 22 by a spring 23. The shaft 22 is driven from a back shaft through a onerevolution clutch and operates the means for feeding the work, making one revolution for each feed of the work. The lower end of the link 16 has a lug 25 which engages at predetermined intervals a headed pin 29 secured to one end of a bell-crank 28. This lever is pivoted to the machine at 27 and at its other end carries a rockable pawl 32 urged to the right, Fig. 1, by a spring plunger 33, the movement being limited by an adjustable stop-screw 35. A further spring plunger 36, weaker than the first, engages the underside of lever 28 and the anticlockwise movement thus promoted is limited by an adjustable stop 38. Abutment members 39 are arranged on a front cam-shaft 41 to strike the pawl 32 and thus operate the lever 28 to engage the lug and headed pin and prevent operation of the stock stop. The shaft 41 makes one revolution for each finished component and, in the example shown the camshaft 22 rotates twice so that, with one abutment member 39, the work stop operates at alternate feeds of the work.

Abstract: 597,534. Hedge-cutters. FIELD, E. July 23, 1945, No. 18854. [Class 6 (ii)] [Also in Group XIV] Relates to motor- and hand-operated hedgeclippers with superposed blades having laterally extending teeth, in which means are provided for reciprocating the blades relatively to each other. According to the invention, a hedgeclipper of this type is provided in which the teeth of the two blades are arranged to cross by bending one or both sets of teeth so that the edges of the teeth rub each other as they pass. Fig. 1 shows a hand-operated hedgeclipper with coincident triangular teeth 3 along one edge of each blade arranged for reciprocal movement of one blade along the other, one blade being provided with slots 8 through which pass bolts 7 carried by the other blade. The teeth of the blades are inclined towards each other either by bending the teeth of one blade out of the plane of that blade towards the second blade or by turning the straight edge of one blade inwards. The clipper is operated by holding a handle 17 fixed to an extension 16 of the bolt carrying blade and oscillating by a handle 21 a lever 19 arranged on a pivot 15 carried on a lateral extension 14 of the bolt carrying blade. Two projections 20 on the inner surface of this )ever 19 engage with a lug 18 on the slotted blade, thus giving a reciprocating movement to this blade as the lever is oscillated. In a modification, Fig. 5, the lever 19 is pivoted on a carrier member 22 and engages with both blades, causing opposite displacement of the blades with respect to the carrier member 22 and thus halving the stroke of the lever 19. The lever 19 may be terminated at the lug 18 and connected through the pivot 15 by a short link 25 to a crank 26 secured on a shaft 27 which is driven by an electric motor.

[Also in Divisions B6 and B8] In a writing, painting &c. instrument comprising a marking point or nib 5 attached to a nib-carrier 4 retractably mounted in a casing 1 having a front aperture through which the rib 5 can be projected for use, means are provided for enclosing the nib when it is retracted comprising jaws 9 situated within the casing which jaws are opened by the outward movement of the nib carrier 4 and are closed by spring action when the carrier is retracted. The nib 5 may be the point of a ball-point pen or a fountain pen, a brush, a cosmetic applier, or a felt point. A gasket 8 engaging the carrier 4 completes the sealing of the space enclosing the nib 5; gasket 8, so that the latter does not exert any frictional drag on the carrier after the carrier has moved a short distance in the projecting direction. In one embodiment, Fig. 1, the nib 5 is a felt nib, the nib-carrier 4 is attached to an ink chamber 3, and the ports 3 . . . 5 are moved by conventional means to projected position against the action of a spring 2. A tubular member 7 is mounted in the casing 1 and within it are slidably-mounted two jaws 9 of resilient material which jaws together form a substantially cylindrical body. Between a shoulder on the member 7 and a ring 10 securing the inner ends of the jaws 9 together is a spring 11. In the position shown, an enlarged conical outer end of the jaws seats upon a conical bore of the member 7, and a space separates the outer surface of the nib 5 from the inside of the jaws 9. As the carrier 4 is moved to projection position, the front end thereof engages a shoulder 13 to move the jaws towards the point end of the casing and then engages an inner surface 17 of the jaws to open them. During this movement the nib 5 does not contact the jaws. Upward rearward movement of the nib carrier 4, the spring 11 returns the jaws to their enclosing position. In a modification of this embodiment (Fig. 3, not shown) the spring moving the jaws to closed position is situated between the outer ends of the jaws and the outer end of the casing 1. According to the embodiment shown in Fig. 5, the jaws 40 are of rigid material and movable radially against the action of springs which may be leaf springs 45 or ring springs embracing the jaws.
