Abstract: 1,081,399. Caps for containers. ILLINOIS TOOL WORKS Inc. July 26, 1966 [July 28, 1965], No. 33609/66. Heading B8T. Ready lateral sliding apart of stacked skirted caps (10), Fig. 3 (not shown), is facilitated by forming the lower edge of each cap skirt (18), Fig. 2 (not shown), with an abutment surface (20), a groove (22) extruding around the flat crown (16) of the cap adjacent the skirt and having its base (28) formed as a sliding surface parallel to the crown and lying substantially in the plane of the abutment surface. The width of the groove base (28) and the spacing between the cap skirt (18) and the outer wall (24) of the groove (22) is such that one cap (10) cannot nest within an adjacent cap on which it rests. The abutment surface (20) may be formed by a peripheral ridge moulded around the lower edge of the cap skirt (18), the cap being made from thermoplastic material. The outer and inner walls (24, 26) of the groove (22) may be parallel to each other and perpendicular to the cap crown (16). The abutment surface and ridge (20) is snapped under the curled edge (14) of a container (12) to hold the cap (10) in place. In another form, the peripheral ridge (20) around the cap skirt (18) is replaced by spaced indentations (30), Fig. 4 (not shown), which snap under the curled edge of a container. In yet another form, the outer and inner walls (24b, 26b), Fig. 5 (not shown), of the groove (22b) in the flat crown (16b) of a cap (10b), are not parallel but diverge with increasing distance from the crown, and the peripheral ridge around the cap skirt (18b) is omitted. The cap (10b) can be removed from a container on to which it has been snapped by insertng the fingers or a tool (not further described) into the tapered groove (22b).

Title: Improvements in or relating to means for preventing pit tubs and the like from running down hill on failure of the haulage rope or a coupling
IPC: B61K7/04
Filed: 1946-11-15
Abstract: 618,713. Vehicle skid brakes. BARTON, R., and ADLER, P. Nov. 15, 1946, No. 33878. [Class 103(i)] A means for preventing pit tubs and the like from running backward on failure of a coupling, comprises a centrerail 3 arranged to be gripped by jaws 11 and 12 non-rotatably mounted on right- and left - handed quick screwthreads 9 and 10, formed on a rod 8 extending transversely of the frame of the pit tub. Rod 8 is rotatably and slidably mounted in slots 7 cut in depending brackets 5 and carries at each end lever arms 15 coupled by rods 18 to a transverse plate 19 at the centre of which is mounted the spring-loaded draw-bar 20. Failure of a coupling results in the expanding draw-bar spring 20, on the last tub, rotating the rod 8, through rods 18 and arms 15, sufficiently to make the jaws 11 and 12 lightly grip centre rail 3 and disengage the hooks 17, integral with the arms 15, from their locking holes in the bracket 13. The grip of the jaws 11 and 12 on the rail 3 is sufficient to drag the rod 8 along the slots 7 as the pit tub starts to run back, thus in combination with rod 18 further rotating the rod 8 until the grip of the jaws 11 and 12 is sufficiently strong to bring the pit tub to a halt. Alternatively, the centre-rail 3 may be replaced by a rope running along the track and the jaws 11 and 12 modified accordingly to grip it.

Title: Improvements in and relating to automatic two-speed rotary tipplers for use in coal and other mines
Filed: 1947-12-23
Abstract: 634,424. Rotary tipplers. TAYLOR, E. Dec. 23, 1947, No. 33920. i[Class 78 (iv)] An automatic tippler of the type comprising an annular frame driven by rollers engaging annular tracks on the frame, is provided with two driving shafts, one of which normally drives the tippler at a slow speed through driving rollers and may be coupled to drive the second shaft which, immediately after tipping, drives the tippler at a higher speed through further rollers, and the rollers of the first shaft are driven through a unidirectional coupling so that they may revolve freely when the tippler is being driven at the higher speed. The shaft 12, Fig. 9, normally drives rollers 11 on which the rings 1 at each end of the tippler frame rests, but after the tippler has turned sufficiently to discharge a tub 6, Fig. 1, into a shoot 22, a cam 30 extending around the face of one of the rings 1 raises a. roller 29 secured to a lever 28 pivoted at 32 to engage a clutch against the force of a spring to couple a sprocket wheel 24 to the shaft 12. The sprocket wheel 24 is connected by a chain 26 to rotate a sprocket wheel 25 on a shaft 15 carrying further rollers 13 on which the rings 1 rest, so that the tippler is rotated at a higher speed : the rollers 11 are coupled by a unidirectional coupling to the shaft 12 so that they rotate freely when the tippier is moving at the higher speed. The cam 30 releases the clutch shortly before the rotation of the tippler is complete, and the rollers 11 then drive the tippler until an angle-section member 39, Fig. 9, on each ring 1 engages shoes 19, pivoted at 18 to raise the tippler frame off the driving rollers 11. The shoes 19, which are formed with stops 20. are each supported by toggle links 37, 38 carrying abutments 40, 41 so that they can break in one direction only. To start the tippler the toggle linkage 37, 38 is broken by turning a lever 35 secured on the same spindle 17a as the lower toggle links 37, so lowering the shoes 19 ; the toggle links are returned to the position in which they support the shoes 19 by the weight of the lever 35. The spindle 17a may be automatically turned to start the tippler by mechanism operated by an empty tub as it is pushed out of the tippler by a full one. The tub 6 is supported on a track 9, Fig. 1, secured to angle irons 8 above a plate 10 on a rectangular framework 2, 7 within the tippler, the framework being stiffened by angle irons 4 and tub-retaining angle irons 5, and carrying side plates 3. The tippler may be mounted directly over a hopper and the shoot 22 may converge toward the bottom.

Title: Improvements in or connected with eyepiece prism systems for use in rangefinders or other optical instruments working on the coincidence principle
IPC: G02B5/04
Filed: 1931-12-15
Abstract: 385,421. Rangefinders &c. BARR & STROUD, Ltd. and STRANG, J. M., Caxton Street, Anniesland, Glasgow. Dec. 15, 1931, No. 34707. [Class 97 (i).] In a rangefinder or other instrument working on the coincidence principle, the separating prism combination of the eyepiece prism system is so constructed that the process of division of the two beams of light depends upon total internal reflection. In the form shown the separating combination consists of a prism M of very dense flint glass having a refractive index of about 1.73, cemented to a prism B of boro-silicate crown glass having a refractive index of about 1À5. With this combination light incident on the interface 2 through the prism M is totally reflected provided the angle of incidence exceeds about 60‹. Light from one end of the rangefinder base enters a prism A and, after reflection at roof faces meeting at the edge 1, passes into the prism M and undergoes total internal reflection at the interface 2 to enter the eyepiece F, G. Light from the other end of the base is reflected downwards by a step prism C, and then horizontally along the axis of the base, and then forwardly at right-angles to the axis, by a prism D, the front surface of which then directs the light upwardly through the prism B to the eyepiece. The front face of the combination B, M is protected by cementing a cover glass E to it. This arrangement gives an inverted image in the upper field and an erect image in the lower field. Two erect images can be obtained by substituting a simple reflecting face for the roof faces in the prism A. The front surface of the glass E may be curved to act as one of the lenses of the eyepiece combination, or it may have a separate lens cemented to it. To prevent relative movement of the two images due to small rotation of the combination M, B, either the beam which is reflected at the interface 2, or the beam which is not so reflected, may be reflected at another surface of the combination. The invention may be applied to range-finders of the kind described in Specification 30152/09, [Class 97 (i), Optical systems &c.], or in Specification 135,223, [Class 97 (i), Optical systems &c.].

Abstract: 639,625. Stone sawing. SCHNEIDER, W. Dec. 30, 1947, No. 34746. Convention date, Nov. 4, 1946. [Class 124] A saw blade for stone sawing has a flat straight cutting edge with a series of straight grooves at right angles thereto and extending across the entire width of the blade, the grooves on one side being opposite to those on the other. As shown, the grooves 2 are spaced apart from one another a distance equal to the width of two grooves and they may have rectangular, triangular, semi-circular, or dovetail section. The blade may be of iron or steel or an alloy of iron or steel or a synthetic resin impregnated with a hard substance, e.g. carborundum. The Specification as open to inspection under Sect. 91 includes also the grooves in staggered relation to one another or on one side of the blade only and the use of cutting teeth fitted to a plain blade of thinner section. The grooves may also be zig-zag, oblique or in the form of corrugations. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to sewing machines
IPC: D05B69/32
Filed: 1953-12-15
Abstract: 743,637. Sewing machines. UNION SPECIAL MACHINE CO. Dec. 15, 1953 [Dec. 17, 1952], No. 34566/53. Class 112. [Also in Group XXXII] Feed by dogs and needle; upper and lower shafts, connecting.-The invention relates to means for preventing the transmission of torsional vibrations to gears 55 to 58 in the drive to stitch-forming elements 51, 52 of a sewing machine. A needle bar 29 is carried in a frame 32 pivotally mounted to the machine frame at 33. The bar 29 is reciprocable by the action of a connecting rod 24 driven by a main drive shaft 15. An eccentric 45 rigid with the shaft 15 imparts oscillatory movement to the frame 32 by acting through a rocker rod (not shown), arm 40, sleeve 20 and arm 36. The shaft 15 is connected by a gear train 64, 63, 62, to a shaft 59. Torsional vibrations are present in the shaft 15 due to the periodic accelerations of the needle bar. A flexible connection provided between the gear 62 and the shaft 59, constitutes a torsional - vibration damper (see Group XXXII). As shown in Figs. 1 and 2, the gear 62 is connected to the shaft 59 through resilient rods 91, 92, and a disc 88 rigid with the shaft 59. The disc 88 may constitute a fly-wheel. In a modified construction (Figs. 5 and 6, not shown) the rods 91, 92 are replaced by an annulus of rubber which is coaxial with the shaft 59 and is bonded on one side face to the gear 62 and on the other face to the disc 88. The shaft 59 drives rotary hooks 51, 52 through the respective pairs of gears 55, 57 and 56, 58. Up-and-down motion of a feed dog is derived from an eccentric 72 on the shaft 59. Feedrocking movements of the feed dog are derived from a feed bar 71 operable by a shaft 76, oscillated by the action of linkage 78, 79, coupled at 82 to the arm 40. The flexibility of the coupling between the gear 62 and the shaft 59 should be such that the resonant frequency of the shaft 59 and gears 55-58 should be “ to ¥ of the speed of the shaft 15. U.S.A. Specification 2,329,484 is referred to.
