Filed: 1927-08-16
Abstract: 276,029. Nicolet, W. Aug. 16, 1926, [Convention date]. Addition to 262,962. Shedding-motions; healds.-In a loom wherein two groups 3, 4 of warp threads are shed by the eyes of combs or healds, so that when the usual shed is formed an open shed is also formed behind it, thus allowing two wefts to be picked simultaneously or in quick succession, as described in the parent Specification, two or more independently-movable combs or bars or thread guides 5a, 5b or 6<a>, 6<b> are used for each group of warp threads, the bars 5a, 5b being moved horizontally laterally relatively to one another, preferably at the same time as the bars move vertically, whereby the correct insertion of the warp threads carried by the teeth on one bar into the gaps between the teeth of another bar is facilitated. In forming the front shed from the position shown in Fig. 1, wherein the warp threads are parallel to one another, the bar 6<a> is first raised, the bars 5<a>, 5<b> being moved laterally and horizontally relatively to one another so as to condense the warp threads into groups as shown in Fig. 2 to facilitate the entry of the warp threads 4a<1>, 4a<2> guided by the teeth on the bar 6<a> between the teeth of the bars 5<a>, 5<b>. Afterwards the bar 6<b> is raised, the bars 5a, 5b being moved horizontall<y> relatively to one another to condense the warp threads into other groups to facilitate the movements of the warp threads carried by the bar 6b. The bars 5<a>, 5<b> are then depressed as shown in Fig. 4, and moved horizontally relatively to one another to return the warp threads to the position wherein they are parallel to one another.

Abstract: 532,880. Cams; actuating brakes. PRATT, J. H., MANLEY, G. E., and GIRLING, A. H. G. July 27, 1939, No. 21794. [Class 80 (iii)] [Also in Group XXXIV] Rotation of an arm 4 produces movement in a direction parallel to the axis about which the lever rotates. As applied to the operation of a brake of the disc type as described in Specification 520,279, [Group XXII], a manually operable lever is connected by a cable or rod to the upper end of the arm 4 splined to a shaft 5 rotatable and slidable in a sleeve 6 carried by a casing 7 secured to the fixed carrier plate 8 for the brake as a whole, a rubber washer 9 being interposed between the plate and casing. Another rubber washer 10 is also fitted closely around the opposite end of the casing and around the shaft 5. This shaft has a flange 5a the face of which is directed to the arm 4 being formed with three equidistant conically sided recesses 5b adapted to accommodate balls 12 spaced by a ring 13. These balls are also adapted to enter similar recesses 14a in a ring 14 pinned at 15 to the casing 7. This ring may be so mounted as to tilt, but it must not rotate. Rotation of arm 4 moves shaft 5 axially and this movement is transmitted through a ball-ended strut 16 to the movable clamping member 17 of the brake. A single manually operable control is thus provided for a brake intended normally to be operated hydraulically. The recesses 5a, 5b may be wedge-shaped and the balls replaced by rollers.

Title: Apparatus for automatically filling well casing
Inventor: BAKER REUBEN CARLTON
IPC: E21B21/10
Filed: 1952-09-09
Abstract: 714,910. Well-casing filling apparatus. BAKER OIL TOOLS, Inc. Sept. 9, 1952, No. 22646/52. Class 85  An apparatus for automatically filling a string of well casing to a predetermined level, as it is floated into position in a well bore, is mounted in or on the casing string as a collar or shoe. It comprises a tubular member 10. 12 in which is secured a two-part tubular housing 23a, 23b. The part 23b has a spider 27, in the hub 33 of which is secured, by frangible set screws 34, a valve seat 30. Within the part 23a, in which the internal diameter of the upper portion thereof is greater than that of the lower portion, there is slidably mounted a tubular valve member 37. that can move from an upper position, in which fluid flows into the casing from the well bore, to a lower position where it engages the seat 30 to prevent said flow. The outer circumferential surface of the tubular valve member 37 is complementary to the internal surface of the housing 27, so that the surface of the member 37 exposed to the pressure of the column of fluid within the casing string is greater than the surface exposed to the pressure of the fluid in the borehole, with the result that the valve 37 is either in engagement with or away from the seat 30 unless there is a predetermined difference in the levels of the fluid within and without the casing. The weight of the valve member is reduced by forming a groove 51 therein, which in conjunction with sealing rings and the housing 37 forms an annular air chamber. A back pressure valve is incorporated in the member 10 above the unit 37, 30 and the ball 18 of said back pressure valve is held clear of the seat 17 during the lowering of the casing string by a rod 29 attached to the valve seat 30 by a frangible screw 31. When the casing is in the required final position, fluid is pumped down the casing, forcing member 37 on to seat 30 and then forcing both members 37, 30 downwards to shear screw 31 as ball 18 is held by fingers 22 on a spacer 21 secured in member 10. The ball 18 is thus released and engages a seat 17 if the pressure of the fluid external to the casing exceeds that within. On the shearing of the screw 34 the valve seat 30 descends and disengages itself from the valve member 37, the descent of which is limited by a shoulder 43 on the housing 23a.
