Title: Electric Door-operators.
Inventor: NAKAHARA TOICH
IPC: E05F15/14
Filed: 1911-12-18
Granted: 1912-08-01
Abstract: 28,488. Nakahara, T. Dec. 18. Operating doors electrically, by treadles and by weights.-In apparatus of the kind in which the door is opened by an electric motor and is closed by gravity, means are provided for retarding the initial closing movement of the door and for maintaining the field of the motor closed up to a predetermined point in the closing movement of the door. The device may be applied to a swinging or sliding door. The circuit of the motor E contains a pair of switches S', S<2> arranged in the path of the opening door A, and a switch G adapted to be closed on the depression of a hinged platform K<1> extending on both sides of the door, The switches S', S<2> comprise spring arms D<3>, F<2> engaging contact screws D<2>, F<1> respectively and are normally closed. When switch G is closed. current passes from main D through switch S<1>, motor E, switch S<2>, lead G<1>, and switch G to return main H. The field circuit is connected at one end to the main D and at the other end to the main H through a switch J<1>, J<2>, which is also closed on depressing the platform K<1> so that the field and motor circuits are closed simultaneously and the door opened until an arm A<5> on the door engages the spring arm F<2>, thereby opening the switch S<2> and stopping the motor. Immediately afterwards a block F<4> on the arm F<2> engages a block D<4> on arm D<3> and opens the switch S', so that the armature is short-circuited through leads E<1>, E<2> and spring arms F<2> D<3>. The field circuit remaining closed, the initial closing movement of the door by the weight C is retarded until the short-circuit is again broken. The means for maintaining the field circuit closed after the platform K<1> is raised comprises a sliding shaft J<5> independent of the platform and pivotally connected to an arm J<6> rigidly connected to the movable arm J<1> of the field switch J<1>, J<2>. The shaft J<5> is provided with an adjustable block J<4>, and the door A with a spring trip member A<6> which trips past the block J<4> during opening of the door but during closing engages the block and moves the shaft J<5> longitudinally so that the switch J', J<2> is opened. The field switch may be dispensed with, the field connexion E<4> being made with the stationary side of the switch G.

Granted: 1912-10-31
Abstract: 14,388. Neil, J. M. June 19. Bag filters; filters, cleansing.-Filters with vertical filtering-surfaces adapted to be submerged in the liquid to be filtered are provided with retainers which prevent the solid matters accumulating on the surfaces from falling off when the filters are lifted out. The apparatus is especially suited for the treatment of wood pulp, sewage, &c. As shown in Fig. 1, retainers 4 comprising a sheet of perforated metal 4<d> on a frame of bars 4<a> are provided on either side of each hollow filter-element 2. The filter 2 is supported in the tank 1 by a bar 3 resting on brackets 1<a>. The retainers are supported from a bar 6 by links 5<a> the lower ends of which are connected to the filter by links 5. With this construction, when the apparatus is let down by chains 6<a> into the tank, the bar 3 and the filter will be arrested first, the retainers continuing to move downwards for a short distance and moving outwards from the filter so that they do not interfere with filtration. When the bar 6 which rests on the top of the tank is lifted again, the retainers close in around the solid matter c before the filters rise. The bottom portion 4<e> of the retainers pass under the lower edges of the layers of material c. A stop bolt may be attached to one link 5<a> to engage with the other link in such a manner that too great a compression of the matter c is prevented. The apparatus is suspended from a carriage moving on a track which extends over washing and discharging tanks. In the apparatus shown in Fig. 8, the filterelement is provided with a frame 2 which has apertures 2<d> at the top and tapers downwards. Retainers 3 formed of coarse screens or lattice work are hinged to the frame 2 at the top and held by spring catches 3<c> at the bottom. The retainers do not prevent the passage of the material for filtration, but prevent the return of the solid matter. Fig. 11 shows a cross-section of a large filter having retainers 3<x> divided into sections suspended by hooks 4 from a suction-header 2<y> which extends across the filter-tank.
