Filed: 1972-06-19
Abstract: 1391209 Boring earth &c DRESSER INDUSTRIAL PRODUCTS Ltd 19 June 1972 [19 July 1971] 28620/72 Heading E1F In the use of a tool 48 for positioning or retrieving a core barrel and which may be pumped down a drill string 50 to retrieve the barrel a seal element 82 is engaged with the string to form a seal during pumping and an actuator 72 is operable to move the element so that it does not engage the string to form a seal. The actuator slides on the body 64 of the tool and is urged to the position shown by a spring 78 and adjuster 80 to compress the element to seal against the string. The element is a ring carried by the actuator and looped about one end of a pin 74 in the actuator and engaged by the spring. When the tool engages a lance 107 on the barrel the actuator is moved upwardly to move the element from its sealing position and the lance is gripped by an inclined, spring-pressed washer 90 so that the barrel may be retrieved. If the barrel sticks during retrieval a pin 94 is forced downwardly to free the barrel and prevent breakage of the line 52 manipulating the tool. In a dry hole. a string special section 70, a retaining pin 66 and the element are not used to place the barrel in the core bit, the tool and barrel being connected and lowered to the bit. On reaching the bit, the inertia of the tool causes the washer to be retained by a spring end 98 to release the barrel to permit withdrawal of the tool. When core drilling upwardly, the tool in conjunction with the special section 70 acts as a check valve preventing drainage of fluid from the hole as a section is added to the drill string.

Title: Improvements in a roller-skate wheel mounting
Filed: 1947-10-27
Abstract: 646,943. Roller skates. PETRELLI, I., and MARES, L. Oct. 27, 1947, No. 28653. Convention date, Oct. 25, 1946. [Class 132 (i)] The body 1 of a roller skate wheel (see Figs. 1 and 2), is lined with a metal bush 2 and is capable of axial displacement against the action of a resilient loading thereby preventing undue lateral skidding especially when the skate is travelling along a curve. In Fig. 1, the wheel body 1 is capable of axial displacement outwardly of the skate against the action of spring 18, but is prevented from moving from its normal position towards the centre line of the skate by the abutment of shoulder 5 on bush 2 against shoulder 5a on hub 3. In Fig. 2, wheel body 1 is capable of axial displacement outwardly of the skate against the action of spring 18, and towards the centre line of the skate against the action of spring 18<SP>1</SP>. In the production of the wheel, the body 1, composed of wood, may be roughly machined, the bore being coaxial with the periphery, and then metal bush 2, provided with ribs, splines or serrations on its outer periphery, may be pressed into the bore. Thereupon the bore of bush 2 may be accurately machined and finally the outer periphery of body 1 may be accurately machined. In this way, exact concentricity of the outer periphery of body 1 and the bore of bush 2 may be ensured in the finished wheel.

Abstract: 798,716. Feeding sheets SMITHE MACHINE CO., Inc., F. L. Sept. 24, 1956, No. 29114/56 Class 100(1) Apparatus for separating envelope blanks or sheets fed in overlapping relation comprises an upper feed roller 48 provided with one or more suction ports, a lower feed roller 94, and a yieldable obstructing member 46 which stops the normal forward movement of the overlapping blanks but allows the roller 48 to pick up the leading blank and carry it forward to a feed bight formed between the two rollers 48, 94. As applied to an envelope making machine the gummed and fanned out blanks are delivered from a drier on conveyer belts 10, their edges being supported and guided by angle bars 16, spring-urged presser rollers 24 and guide fingers 34 arranged adjustably on rails 30 assist the delivery operation of the overlapped blanks up to the obstructing member 46. The member 46 comprises a rubber block 44 fixed in a metal channel 50 tiltable about a bolt 52 which is slidable vertically in a slot 54 in a fixed block 56. The block 44 has a arcuate face bearing against the roller 48, and is maintained normally in that position by a stud 64 having screwthreaded connection with a bevel gear 72 in mesh with a manually-operated bevel gear 78; thus the block 44 can be adjusted during the operation of the apparatus. When the leading blank of the fanned-out stack of blanks is picked up by a suction port on the roller 48, the block and channel 44, 50 are rocked about the upper end of the stud 64 to allow the blank to pass. The two rollers 48, 94 are geared together, the roller 94 being urged upwardly, to a position limited by an adjustable stop, by spring means, such that only one blank can pass between the rollers. The shaft 90 of the roller 48 is driven by gear-wheels from a power-operated shaft 84 on which is a feed roller 179 which co-operates with an upper roller 180 to feed each blank to aligning pins on a pin conveyer 14. The suction roller 48 is driven at uniform speed, and is provided with diametricallyopposed recesses 110 in which similar blocks 112 are secured. Within each block 112 is a short metal suction tube which has an enlarged screw-threaded portion engaged by a nut 175 which can be rotated to adjust the outer end of the tube relatively to the periphery of the roller. This tube is fitted with a rubber sleeve 174 which extends beyond it to form a soft sucker mouth for engaging the envelope blanks. The inner end of each suction tube is within an axial air passage in which suction is established once in every rotation of the roller 48 with a similar passage in a stationary suction valve member 122 connected by a pipe 116 to a source of suction. The member 122 fits loosely on the shaft 90, and urged towards the roller 48 by springs arranged between the member 122 and a plate supported by a bracket 130 secured on a bar 132. Specification 378,466 [Group XVII] is referred to.
