Title: Improvements relating to electric insulators
IPC: H01B17/02
Filed: 1931-05-27
Abstract: 372,571. Insulators. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Ohio Brass Co. ; Mansfield, Ohio, U.S.A.) May 27, 1931, No. 15495. [Class 36.] In order that an insulator may be given a high mechanical strength without increasing its liability to damage by changing temperature conditions, a reinforcing or stress exerting band is applied, subsequently to assembly of a metal and a dielectric part of the insulator, to one of the parts. In the construction of Fig. 1, a metal cap 12 is cemented to the head 11 of a dielectric shell 10. The cap 12 has bearing shoulders 16 and may have a thin sheet metal lining 17 corrugated to permit expansion. A reinforcing band 19 is applied over the tapered edges of the cap 12. The band 19 may be applied by hydraulic pressure, or the ring may be applied hot to the cold cap. The reinforcing band may be of composite structure, and the cap edge may be slit and reinforced with helically wound spring wire. Compensating members, consisting of segments surrounding the pin in the pin cavity may also be provided, and the pin may have a tapered thread. A reinforcing band may be similarly applied to a bushing insulator. The insulator pin may be of the form shown in Figs. 11, 15. A steel pin 66 has a portion 67 with slots 68, the portion 67 being threaded to receive a thimble 69. In a modified pin construction, the pin is made hollow and is provided with tangentially directed slots, or a metal sleeve may be threaded about a central spindle. The sleeve may consist of separate collars each bearing a resilient flange. Fig. 18 shows a reinforcing band for the insulator cap. The band 88 is of drawn metal and has a radial flange 89. A band 90 may reinforce the band 88 as shown. Fig. 19 shows a pin having a reinforcing spider 92 within the outer shell 93, which may be slotted. In order to secure accurate compression, the reinforcing band may be corrugated or formed with spaced contacts bearing on the cap, or a corrugated sheet of metal may be inserted between the band and the cap. Fig. 20 shows an apparatus for applying reinforcing bands to insular caps. A frame 96 fits over the cap 97 and bears on the reinforcing band 98. A threaded pull-bar 99, with a head 100 which fits a socket 101 in the cap, carries a screw head 102. Rotation of a hand-wheel 104 will press down the frame 96 to exert tension on the bar 99 and force the band 98 on to the cap 97. For relieving pressure on the band, the device shown in Figs. 21 and 22 may be used. A spider 105 has pivoted grappling hooks 106. A head 108 bears on the cap 97 and is adapted to press on the cap 97 by a screw 109 which is rotated by a hand-wheel 110 in the yoke 105. Springs 111 hold the grappling hooks 106 in the upper position. A band 112 encloses the hooks 106 and is adapted to force the hooks into position beneath a reinforcing band 98. The yoke 105, hooks 106 and band 98 are lifted to relieve pressure on the cap 97 by rotation of the hand-wheel 110.

Abstract: 355,791. Feeding devices for granular and like materials. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Cornell Bag Corporation ; 60, East 42nd Street, New York, U.S.A.) May 22, 1930, No. 15747. [Class 59.] A device for feeding powdered, granular or other finely divided material, suitable for example for filling bags with cement, comprises a conveyer screw with a hollow core working in a discharge tube, the conveying surface of the screw being formed so as to press the material inwardly into the space within the screw. The conveyer screw 25 is mounted with clearance in a tube 13 which is open at the top to the interior of a hopper 11. The screw thread is of substantially triangular cross section, as seen in Fig. 3, so that the face 33 exerts an inward pressure on the material adjacent to the tube and forms a compacted column of material within the screw and forces it towards the discharge end 18, 19. The tube and screw are tapered at this end, as shown at 17, and the cross section of the thread is reduced so that the free cross section of the tube is constant. In a modification, Fig. 4, the end 37 of the screw is of reduced diameter and increased pitch so as to break up the compacted column of material and accelerate its discharge. The clearance at 38, Fig. 1, between the screw and the tube causes the formation of a cushion of material which minimizes friction and rotation of the material, and increases the rate of discharge, especially at high speeds. A double-bladed screw 26 is mounted in the hopper above the conveyer screw in order to feed the material away from the discharge orifice and so keep the conveyer screw fully charged. The screws are preferably geared together and the feed screw may be driven at oneninth the speed of che conveyer screw, or in an example the feed screw is driven at 100 and the conveyer screw at 1900 r.p.m.

Abstract: 291,453. Naamlooze Vennootschap Mij. tot Beheer en Exploit. van Octrooien. June 3, 1927, [Convention date]. Charging and discharging; charges, conveying. -Glass plates or other articles are delivered intermittently to a conveyer of such a construction that the first plate is conveyed at a low normal speed and the second and all succeeding plates are conveyed at a speed higher than the normal speed until they have overtaken the preceding plate, whereupon they are carried forward at the normal speed. The conveyer is stated particularly to be intended for transporting glass plates from the place of formation to and through a leer and behind the leer as bv its use in connection with the rolling of glass plates from single pots, the intermittently produced plates follow each other on the conveyer without any appreciable distance betwen them. The rollers e are driven at a low normal speed by a common driving shaft c through bevel gears b, a and pawl- and-ratchet mechanism f, g. A higher speed is imparted to the rollers by racks h through pinions i. The racks h are moved in the direction of feed by pinions p driven through bevel gears u, v by a common shaft u<1>. A motor r drives the shaft u<1> through a clutch o and bevel gears s, t. Each rack bar has a stop n provided at its rear end and an angular lever q at its forward end. When a rack bar overtakes a bar moving at the normal conveying speed, its lever q encounters the stop n and is swung so that the contact roller k is raised out of contact with the lines l, m and the clutch o is released. All the rollers are now driven at the normal speed by the shaft c. The foremost rack bar is now removed, carried back to the point where the conveyer receives the next plate, and replaced on the pinions i, p with the roller k in contact with the lines l, m. Similar mechanism may be used for separating the plates when they have emerged from the leer and have to be submitted to further treatment.
