Title: Improvements in or relating to devices for attaching belt fasteners
IPC: F16G3/00
Filed: 1935-03-13
Abstract: 444,847. Attaching belt - fasteners. BRÍKING, E., and GARTHE, P., Gevelsberg, Westphalia, Germany. March 13, 1935, No. 7851. [Class 80 (i)] In a device for pressing V-shaped staples into belt-ends of the type comprising two oscillatable jaws and a comb for holding the staples, the plane surfaces of the jaws are arranged at right angles to the radial direction, or slightly inclined to this direction, and the comb is displaceable in a plane symmetrical to the said axes of oscillation. In the form shown, the staples K are supported by a comb 21 mounted on a slide 7 movable between guides 30, 31 by a screw 13 operated by a handle 11. As the comb 21 is moved to the right from the position shown, the levers 1 carrying the press jaws 22<1> straighten up like a toggle joint and press the hooks into the belt end. The snap-over position may be slightly overshot. During the whole movement the levers 1 are kept against the outer edge of the comb 21 by a spring 14 passing through a hole in the slide 7. To ensure that the jaws 22<1> shall be the correct distance apart at the end of the pressing movement, the thickness of belt is gauged by a graduated series of numbered notches 53. The eccentrically mounted pivots 5 of the levers 1 are then adjusted by linkwork from a wheel (not shown), having graduated notches in its periphery which correspond to the notches 53 and are engageable by a spring-pressed locking-pin. The jaws 22<1> are mounted with play on the ends of the levers 1 so as to permit the jaws to come parallel to the surface of the belt during the concluding part of the movement. The jaws may be pivoted on the levers, or secured thereto by tension springs 47, Fig. 5, loose locating pegs 51 being provided. The handle 11 is normally secured symmetrically to the shaft 13 by a spring-pressed ball 55 engaging a notch 58, but towards the end of the movement the handle is slid to the full-line position, to get greater leverage.

Abstract: 402,301. Combined sound and picture films. DONELLI, A., 43, Via Balbo, Rome. March 16, 1933, No. 7980. Convention date, March 16, 1932. [Class 40 (ii).] A combined sound and picture film of reduced size, Fig. 2, is made by printing from a normal film, Fig. 1, in such a manner that the picture " frames," having their length and width proportionally reduced, are turned through 90‹, so that their shorter sides are adjacent, and the distance X between the centres of adjoining pictures is the same in the reduced film as in the normal film. With this arrangement, sufficient marginal space is left to enable the sound trace D to be printed without any reduction in dimensions ; moreover, space is provided between the reduced picture frames for sprocket holes M. In projecting the reduced film, it may be run horizontally, or it may be used in a machine provided with a prism or equivalent device for turning the images through 90‹, so that the film may in this case move vertically.

Title: Improvements in or relating to circular looms
IPC: D03D37/00
Filed: 1926-03-29
Abstract: 266,160. White, A. E., (Wiremold Co.). March 29, 1926. Circular looms. - Operating and guiding the shuttles- The warp threads 24 are moved up and down in slots 23 in a fixed drum 19 to form the shed, and the shuttle or each shuttle is moved in a horizontal circular path to insert the weft at the weaving point 62 by means of a corresponding notched driving-disc 70 on a shaft 71 mounted in a bracket 72 on a rotating cam drum 39, or on some other driving-frame rotating about the axis of the loom. The disc 70 is partly embraced by a block 75 on the shuttle provided with a curved lower part. A bevel gear 73 on the shaft 71 engages teeth 74 on a fixed gear 57, so that the driving-disc 70 is rotated as it moves around the loom carrying the shuttle with it, the notches in the disc engaging successive warp threads, so that friction is reduced. The outward pressure of the shuttle due to centrifugal action is taken up by the engagement of one or more oil-soaked wooden shoes 66 on the shuttle with a fixed annular bearing surface 69 formed by an annular slot with an inclined wall 77 in the inner face of the drum 19. The block 75 may be formed of oil-soaked wool, and the driving-disc 70 of polished metal, such as steel, or vice versa. The shuttle is supported at its inner end by a slotted warp ring 53 fixed to a plate 55 secured to the fixed gear 57, the hub of which is secured to a fixed hollow shaft 40. A ring 83 on a hub 81 secured to an arm 82 extending from the fixed drum 19 prevents upward movement of the shuttle. Shuttle construction. The shuttle frame 52 has a guide 63 with upper and lower bars 64, 65 for forcing open the shed. The weft from the spool 59 passes through a tensioning device 61 to a guide 86 on a plate 84 adjustably secured to the frame 52, a rounded part 87 on the plate 84 assisting to open the shed. Each shoe 66 is secured to the shuttle by a screw, and the block 75 is secured in a socket in the shuttle. Warps, guiding and shedding &c. The warp threads are guided by fixed eyelets 25, 26 and after passing through the slots 23 are shed by healds 28 having shoes 36 operated by camgrooves 35 in a disc 34, 39 having a hub journaled on the fixed hollow shaft 40. The disc is driven by a bevel wheel 46 on a shaft 47 furnished with fast and loose pulleys operated by a strap passing upwardly through a platform 42. The fabric may be woven round a flexible core 79.

A valve comprises a body member with a throat orifice 33, Fig. 3, connecting the valve passages 36, 37, a valve closure member 16, operated, e.g. by a handle screwing on the valve casing 10, the members having opposed surfaces abutting in the valve closed position, e.g. 61, and the lower end of the closure member, an annular recess 44 in one member, e.g. the seat, with its open side facing the other member and containing a resilient 0-ring 31 whose crosssection diameter is greater than the width of the recess, the base of the recess being in fluid-pressure communication with one of the valve passages, and the other member having an annular portion 57 for making sealing contact with the ring in the valve closed position, a portion of the exposed ring adjacent the contact being exposed to fluid pressure in at least one valve passage. When inlet pressure is applied at 36, it acts around a ring-retaining member 46 in the space 39 above the 0-ring while outlet pressure reaches the base of the recess at the joint 34, 62. When inlet pressure is applied at 37, the space 39 appears at the bottom of the recess. In Fig. 9, the ring 74 is retained in a recess 133 in the closure member 131 by a member 94 ported at 98. On closing, the seat 124 contacts the surface 143 of a guard ring 136 slidable on the member 131 against a spring 141 until the seat corner seals with the O-ring. The spring may be dispensed with, in which case the guard is formed to curl under the 0-ring slightly. The guard may be integral with the closure member, the seat being raised or recessed where it contacts the O-ring; Specification 662,448 is referred to.
