Abstract: 223,110. Prouty, G. W., and Terkelsen Machine Co. Feb. 5, 1924. Packeting by wrapping-up.-Relates to machines for wrapping annular articles such as tyres, coils of wire or hose, &c., in strips of paper,. burlap, &c., and for wrapping rolls of material. The article W is supported on rolls 17, Figs. 2 and 3, each comprising two component parts relatively adjustable on shafts 13, 14 by means of screws 19 to accommodate various sizes of tyres. The article is supported at the top by a weighted roller 62 on a link 60 adjustably pivoted to a standard 58. In order to introduce the article within the shuttle 66. a hinged portion 81, Figs. 3 and 7, normally secured by a bolt 84, is released by rotating a pinion 91 to withdraw the bolt. The shuttle is supported by rollers 64, 65 and a .driving wheel 23 all on a support 63 pivoted at 21, and is rotated bv bodily elevating a motor 25 on a parallel link motion 31, 33 by a hand lever 36 so that the driving wheel of the motor is in frictional contact with the wheel 23. The shuttles support 63, pivoted at 21, is supported by a spring plunger 73 and is secured in the desired position after the introduction of the article into the shuttle by a clamp 77 on a bracket 75. The wrapping material S is drawn from a supply on a drum 97, Fig. 3, on a stud 100 and passes over a roller 112, between knives 130, 131, and through a slot 96. Fig. 6, in the flange 95 of the shuttle. The strip passes to the article W through tension members 115. 116, across a plate 117 with graduated rollers 128 for turning back one edge, and around a roller 118 which is tapered and mounted on a bearing which allows tilting. As the strip S is wrapped around the article W, the rotation of the shuttle causes the strip to be drawn through the slot 96 and to be wound upon the annular flange 95. When a sufficient supply to cover the article to be wrapped has been drawn from the supply, knives 130, 131, Fig. 3, sever the strip, and a brake is applied to the drum 97. A cam 157, Fig. 3, on the shuttle moves a bell and lever 154 at each rotation to rotate a ratchet wheel 141 by means of a pawl 153. After a predetermined number of revolutions of the shuttle, a pin 152 on the ratchet wheel engages a lever 139, which applies a band brake 149 and operates the knives 130, 131. In order to force the beaded edges of the tyre together before arriving at the wrapping position, curved arms 164, Fig. 9, are mounted on an extension 161 of the yoke 163, and carry rollers 169 adapted to bear against the edges. The arms are geared together by pinions 165 and are opened by the operation of the starting lever 36. The fulcra of the pivoted levers operate in slots 162 in the extension of the yoke and are moved by links 171, 174 into the position required by the adjustment of the yoke.

Title: Improvements in and relating to time controlling devices employing electrochemical action
Inventor: ERWOOD CHARLES WILLIAM
IPC: H01H43/32
Filed: 1957-02-01
Abstract: 1,148,901. Timing. MINISTER OF TECHNOLOGY. Feb.12, 1958 [Feb. 1, 1957], No.3537/57. Heading G3T. [Also in Division C7] An electro-chemical delay time controlling device has a timing member which forms the anode of an electrolytic cell and which is made of metals which pass into solution when an electric current is passed through the electrolyte, the timing member having a weak section at which it breaks after a determined amount of electrolytic action to initiate a desired action. As shown in Fig. 1 the timing members comprises a tube 1 closed at one end against which a rod 2 presses under the action of a spring (not shown). The tube 1 comprises an outer layer 8 of a more positive metal e. g. lead, and a thin inner layer 5 of a more negative metal, e.g. silver, the layer 5 having a weak circumferential section 6 of accurately known thickness. The tube 1 is assembled as the anode of a cell containing a solution of lead perchlorate and optionally a small percentage of peptene and having a lead cathode and a current of given strength is passed through the cell, the value of the current being determined by the delay time required. The quantity of lead in the layer 8 is such that it is completely removed after a given time after which the silver in the layer 5 begins to dissolve and eventually the weak section 6 breaks permitting the rod 2 to move. The arrangement is such that the time for the lead to pass into solution is at least twenty five times that required for the silver layer to break whereby the overall time delay is maintained accurate. To further improve the accuracy of timing a very thin gold layer 7 is interposed between the layers 5, 8 except in the region 6 whereby the electrolytic action on the layer 5 is confined to the region 6. A further very thin gold layer 4 may be provided on the inner surface of the silver layer 5 to prevent the passage of electrolyte into the tube through pinholes which may be formed in the silver layer. An innermost copper layer 3 provides a base for the layer 4. The tube 1 is manufactured by successively electro-depositing the various metal layers upon a cylindrical stainless steel former Fig.2 (not shown) and afterwards removing the former by exerting a radial compressive stress on the tube whilst the latter is rotated. In a modification the layer 5 is copper whilst in another construction the layer 8 is copper or nickel; further the layer 7 may be of platinum or palladium. The Specification gives the actual dimensions of a typical timing tube.

Abstract: 165,437. Fischer, H. L. June 24, 1920, [Convention date]. Pencil-holders.-A screw-propelled pencil is provided with means for varying the screw thread engagement of the carrier in the holder when pressure is put upon the projected lead. As shown the lead carrier 18, Fig. 6, is located in a slotted driving-member 16 and has a flat thin body portion notched at 19 to engage threads 20 on a tubular member 11 rigidly secured at its ends to the pencil barrel 10. At its rear end the lead-carrier is formed with a spring finger or tongue 24 which keeps the threaded parts yieldingly in engagement, the forward end of the driver being provided with a lead-receiving socket 26 at the end of a spring finger 25 which also serves to keep the parts in frictional engagement. Excessive pressure on the lead causes the lead-carrier to vield and slip over the threads on the member 11, the lead being returned to its housed position. The forward end of the slot in the driving-member is closed by bending down the lip 22, the rear end being provided with an operating-head 21. To indicate the length of lead remaining in the holder, the driving-member is pulled out until the lip contacts with the notched portion of the carrier, and in this position the distance between the rear end of the pencil barrel and the operating-head is a measure of the lead remaining. An audible click is heard at the limit of travel of the lead-carrier in either direction. The lead-carrier and driving-member are removable together.
