Title: Buttonhole sewing machine
IPC: D05B73/12
Filed: 1924-02-27
Abstract: 225,748. Fairweather, W., (Singer Manufacturing Co.). Feb. 27, 1924. Clutches, ratchet; operating clutches.-An auxiliary shaft 107 which actuates the clamping and cutting mechanism &c. of a button-hole sewing-machine is caused to perform a two-stage movement by being at intervals clutched to and declutched from a continuously running belt-driven wheel 148. A clutch-disc 111 on the shaft has a pair of slideways set at about 120‹ apart and receiving slide-blocks 114, 115 which are interconnected by a link 116 and a bell-crank lever 121 stressed by a spring 124. Lugs 127, 130 project from the slide-blocks and are adapted to engage successively a clutchcontrolling lever. Cam-plates 129, 131 are let into the disc 111 at the same distance apart as the slide blocks. A ring 134 on the face of the disc 111 carries three clutch-roll operating levers 136 which are actuated by cams on a disc 143 having a slot 146 therein which receives a roll 147 on the link 116. The movement of the slide-blocks inwardly moves the levers 136 to press back the rolls 138 from engagement with a flange 150 on the pulley 148 and declutch the disc 111. The movements of the slide-blocks are controlled by a clutch-lever 152 of known type pivoted at 153 and having an extension 154 provided with a cam-slope 157 which engages one of the projections 127, 130 when the lever is moved into juxtaposition with the disc 111 to stop the disc. Rebound of the shaft is prevented by a latch 156. The movement of the lever 52 into and out of clutch-releasing position is controlled by the engagement of a pin 161 on the lever with a cam-groove 160, Fig. 21 on the hub of the disc 111, this groove ensuring the return of the .lever to clutch-releasing position after it has been displaced to start the shaft 107. The partial rotation of the shaft 107 preparatory to sewing is initiated by the depression of a finger lever 164 the rear end of which engages a bellcrank lever 168 connected by a link to the lever 152. Specifications 18153/03; 4417/08, [Class 112, Sewing &c.]; and 146,587 are referred to.

Abstract: 644,117. Motor - vehicle headlights. HOLM, K. O., PETTERSSON, E. V., and LUNDBERG, J. V. Feb. 26, 1948, No. 5721. Convention date, Feb. 26, 1947. [Class 75(iii)] In motor vehicle headlights angularly adjustable vertically and laterally by the steering control and wherein the headlights are turned laterally through different angles, each headlight 1 is non- rotatably mounted relative to a rod 4 which is longitudinally displaceable by a cam 16 against the action of a spring 6, said cams being mounted on a horizontally disposed shaft 17 which is rotated by means of the steering control and said rods 4 being provided with helical formations 9 which guide the rods so as to rotate them during their longitudinal movement. As shown each headlight 1 is mounted on a tube 2 the top end 5 of which is closed and attached via a ball joint 3 to a resilient mounting bracket 28. The tube 2 slidably receives the rod 4 which is formed with a longitudinal rib 7 engaging a recess 8 in the tube, and the spring 6 is interposed between the rod 4 and the top end 5 of the tube. The bottom end of the rod 4 carries a cam-engaging piston 14 sliding in a cylinder 13 of a casing 24 which encloses the cam 16 and is secured to the car body 25 via a resilient bracket 29 in such a position that the rod 4 and tube 2 are inclined rearwardly of the vertical to cause depression of the headlight on rotation of the rod and tube. The rib 7 is formed with a helical portion 9 which merges into a longitudinal extension 10, the rib portion 9 being engaged by a recess 15 formed in the cylinder end cap 12. The headlight on the side towards which the wheels are turned is caused to turn laterally through a greater angle than the opposite headlight by arranging the two cams so that one causes a greater upward and lesser downward longitudinal displacement of its rod 4 than the opposite cam. In an alternative arrangement using two similar cams, one helical rib portion 9 may have a larger pitch above and smaller pitch below the point of normal engagement with the recess 15 than the other rib portion 9. The headlights may have optical systems to provide two sharply defined light spots on the road surface close to the path described by the outermost parts of the vehicle to indicate to oncoming traffic the position and direction of the vehicle.

Abstract: An article containing natural or synthetic rubber is provided for decoration or protection against deterioration by oxygen, ozone, or oil, with one or more adherent layer or layers of an organic polyisocyanate modified polyester or polyester-amide cured by treatment with formaldehyde or a formaldehyde liberating substance. The polyisocyanate modified material, may be bonded to the side walls of tyres, especially when pigmented white, or may be formed as an outer sheathing on natural or synthetic rubber hose or on an electric cable covered with natural or synthetic rubber, or a conveyer or other belt of natural or synthetic rubber may have a protecting surface layer of the material.  An organic polyisocyanate may be used as an agent for bonding the material to the natural or synthetic rubber.  In an example a sheet of vulcanizable tyre compound of natural rubber is painted with a solution of diphenylmethane diisocyanate in a mixture of xylene and methyl ethyl ketone for bonding it to a sheet prepared by milling 100 parts by weight ethylene glycol/monoethanolamine/adipic acid polyester amide modified with hexamethylene diisocyanate, 20 parts titanium dioxide, 0,3 parts stearic acid, 7,5 parts hexamethoxymethylmelamine, and 0,75 parts 2 : 4 dichloro/naphthol.  The latter is coated with a solution of diphenylmethane diisocyanate and uncured diisocyanate modified polyesteramide in acetone and xylene.  Both coatings are allowed to dry and are then placed in contact and the assembly vulcanized in a mould for 45 minutes at 141 DEG C.  Alternatively a polyester of ethyleneglycol and an 87 : 13 mixture by weight of adipic and phthalic acids modified with hexamethylene diisocyanate may be bonded to the rubber using on both surfaces a bonding solution of triphenylmethane 4 : 41 : 41 tri-isocyanate in methylene chloride.
