摘要： 710,709. Temperature-responsive actuating-elements. HOWELL, F. T. Aug. 5,. 1952 [Aug. 4, 1951], No. 18501/51. Class 64(2) [Also in Group XXXVII] A thermostat of the kind comprising a bimetallic or like strip carrying a contact adapted to make and break connection with a fixed contact, has its strip 12 in the form of, or fitted with, a thin flexible springy strip which is mounted to flex freely at one end and which is weighted at 19 within its length. By adjusting the position of the thermostat the effect of gravity on the strip, and hence the normal distance between the contacts, can be varied within predetermined limits. In the construction shown, a supporting strip 10 has fitted to it a magnet 21 for ensuring a sudden opening and closing movement of the switch, a damping plate 13 for securing the strip 12, and a spring clip 23. The latter combines with a rubber bung 18 for holding the assembly in a glass tube 22, which tube passes through holes in the limbs of a U- strip 24 rotatably mounted on a rubber sucker 25. When the device is mounted by the sucker on the wall of a tank, the pull exerted by gravity on the weight 19 in the direction towards or away from the strip 10 can be varied by varying the angular position of the whole device about the sucker 25, thus varying the distance separating the contacts 11, 16. In a modification, Fig. 4 (not shown), the weight is of steel and is arranged opposite the magnet.

摘要： 187,704. Howell, J. T. July 22, 1921. Pianoforte bridges.-In a pianoforte or similar musical instrument the bridges 1 for the strings 5 are made of moulded metal, the lower bridge being screwed to a wooden strip 2 adhesively secured to the sound-board and the upper bridge being preferably screwed directly to the wrest-plank, although a wooden strip may be interposed, if desired. A sheet of felt 4 may be placed between the bridge and the strip 2. The strings are tensioned by means of adjustable bars 6. If desired, a wooden block 10 covered with felt or similar material is arranged between the upper bar 6 and the wrest pins 9.

摘要： 15,665. Idris, T. H. W., Griffith, R. H., and Idris & Co. July 31. Siphon bottles.-The horizontal channel c, by which the liquid passes from the passage b to the nozzle, is made D-shaped as shown in Fig. 1. This gives a large flat surface d on which the washer may bear and prevents it from being drawn into the channel c and so causing spluttering. Preferably also the channel is eccentric to the passage b as shown.

摘要： 1370. Thomas, H. D. Jan. 27. Locking nuts.-A locking washer blank is shown in Fig. 11. It is slit on the dotted line 13, and the projection 9 is bent down so that the loose part 17 forms an inclined plane preferably inclined in the opposite direction to the thread of the bolt. When the nut is being screwed up, one pane of the nut engages the edge of the part 17, and the washer rotates with the nut, but the incline resists any return movement of the nut. As shown in Figs. 12 and 13, the washer may be formed by coiling a wire and turning down the end 19, which is sharpened.

Siphon vessels.- Siphon heads of the kind described in Specification No. 19,643, A.D. 1899, are so constructed that the lever fulcrum is nearer the plunger and that the cap may be removed without disarranging the lever. The earthenware &c. block f, Fig. 1, made with a groove j communicating with the outlet, is surmounted by a diec washer k, which is pressed over the passage h by the spring-held plunger m. The lever p is fulcrummed near the bottom of the slotted tube o , which is screwed into the cap o. Fig. 2 shows a modification in which the lever p is supported on the flange t of a disc t.

摘要： 12,555. Idris, T. H. W., and Idris &. Co. June 3. Stoppers. - Caps, which screw on the necks of bottles, are constructed so as to present an even lower edge unbroken by the screw threads, so as to engage the neck securely. The necks of the bottle are provided with triplethreaded screws, which engage three series of helical indentations b formed in the cap a. The cap a is formed with a milled or beaded upper edge c, to give a better hold when turning it.

摘要： 19,643. Idris, T. H. W., and Griffith, R.H. Sept.30. Siphon bottles.-The object of the invention is to simplify the construction of siphon heads, and to prevent the liquid from coming into contact with metal. The head is made up of a metal tube a, Fig. 2, which is screwed on to a split ring c, and of a rubber washer e, which rests on the top of the bottle b, and upon the upper side of which rest both the flanged upper end of the tube d and a block f of earthenware or the like, which has the nozzle g made in one with it and has a central passage h and a groove j at the top. The nozzle g projects through a slot in the tube a. On the upper side of the block f lies a washer k, which acts as a valve, and is normally pressed down by a spring n acting on a plunger m, the whole being held in place by a cap o which is screwed on to the top of the tube a. The valve is opened by a lever p, which passes through a slot in the cap, is fulcrumed on the edge of a ring l, and is engaged with a slot in the plunger n. In the modification shown in Fig. 5, the valve washer k is operated by a rotating cap q, which turns a screw r working in a fixed nut in the cap a' and having its end resting on the washer k. Inside the cap q are springs s, Fig. 6, which tend to bring it back again when released and thus close the valve k.
