Granted: 1898-07-30
Abstract: 24,014. Jamain, P. E. M. Oct. 18. Moulding lozenges, tabloids, &c.-Relates to improved feeding-apparatus for the press described in Specification No. 23,355, A.D. 1897, and means for ensuring an equal compression of the powder within the moulds. An additional feed-reservoir 56 is provided above the ordinary hopper a, and the powder is supplied to the hopper by an oscillating perforated cylinder 53 similar to the cylinder c. The cylinder 53 derives its motion from the cylinder c by means of toothed wheels, and carries pistons 54 adjustable by screws 55 for the purpose of regulating the supply of powder. To ensure the production of lozenges of equal density, the dies or punches 6, 7 are brought to the required distance apart, so that the powder fills the spaces between them instead of falling into the moulds and forming cones at the bottom. To obtain this result, the dies carried by the sliding frame 12 are returned within the mould by auxiliary levers 48, which are actuated by cams and are adjustable by a set-screw.

Granted: 1900-04-07
Abstract: 8672. Lewis, A. April 25. Motor road vehicles.-Relates chiefly to the suspension of the batteries, to the independent operation of the driving-wheels, to the control and reversal of the motors, and to the warming of the steering-handle. Fig. 1 shows a side elevation of the carriage, and Fig. 2 a part section on the line 2-2, Fig. 1. The frame of the undercarriage is composed of tubes B', connected by loose joints which permit relative movement in passing over uneven ground. The batteries E are mounted independently of the body of the vehicle on a tray supported in a casing C<4> by springs C<1> on hangers depending from the wheel frame. This arrangement enables different carriage bodies A to be used with the same undercarriage. The motors B<5> are suspended at the back by eyes embracing the rear axle, and at the front by a lug held between springs, above and below, carried by a hanger. The motor has two separate armatures, e a c h driving one of the hollow axles a<16>, a<17> of the driving- wheels independently. The starting, stopping, reversing, and regulation of speed and power are effected by a rotary cylindrical series parallel controller, which is operated by electromagnetic and ratchet gear by means of push-buttons conveniently disposed in a certain handle. The controller actuator system is shown in Fig.15. The controller spindle g<28> can be rotated step by step in either direction by the ratchet mechanism shown, which is operated by electromagnets g<6>, g<18> by push-buttons at g<1>, g<16> arranged in the handle referred to. A third pushbutton, at g<20>, enables a sudden stop to be effected through the medium of an electromagnet g<22> by which the circuit opener I is operated. Means are provided for effecting the automatic return of the controller when the circuit opener is used, depending on the closure of certain other circuits by the switch I and the action of certain contacts shown at the left of the Figure, but actually disposed on the controller spindle. The arrangement of the contacts and circuits for putting the batteries in parallel, for putting them in two parallel groups in series, or all in series, and also for reversing, and for charging the batteries from an external source, are set out at length in the Specification. Steering is effected through short swivelling axles at the front, which are connected together and to a handlever b<10>. This, as shown in Fig. 6, is connected by brush contacts to an electric bell d, which can be operated by a push-button d<6> in the handle, and with a battery E by which warming-coils k can be heated on inserting the switch k<5>.

Granted: 1900-04-21
Abstract: 25,759. Kunzelmann, K. Dec. 30. Locks, key and permutation, for safes, strong-rooms, &c. The keyhole on the door 1 is closed by a device 21 provided with a spiral spring 25 and a shaft 22 in a recess 27 of which a bolt 26 is engaged. This bolt is operated by a lever 29 from a cam 30 on a sleeve 31 of the shaft 16 of the rotary handle 3. The handle is held in the lock by a bolt, and can only be rotated when the flat bar 13 of a bolt 12, normally engaging in a groove 14 on the shaft 16, is moved into aligned recesses of a combination letter arrangement of rings 6 and discs 11 on a sleeve 4 and flange 5. In a modification, a conically-ground closing-device for the keyhole is engaged by a piece on the inner end of a separately-arranged rotary handle. When the closing-device is removed, the key is inserted into the casing 23 and turned so that a pin A, projected from the bit of the key, enters a hole in a plate 24 and presses a projection of a spring 41. When the key is now rotated, the plate 24 is moved until its keyhole 40 corresponds with the keyhole 39 of the casing 2, and the plate is held by a pin 45 and an engaging-piece 47 on a spring 46. The key is then pushed so that its hollow shaft slides over a hollow pin 73, and a pin B on the key is pressed against a pin 75 in the pin 73, so that the spring 46 is pressed and a pin 83 on the bolt 50 is released from one of the holes 84 in the spring. The bolt 50 can now be brought into the looking position by turning the key twice against contact faces 52, 53, lifting tumblers 49 on the bolt. Another turn of the key lifts a piece 54. A second bolt 51 is operated by the handle 3, and the pin A of the key is projected into an orifice 77 in a plate 74, and a spring 71 is pressed, whereby a projection 66 of a lever 64, 65 enters a recess 67 of corresponding plates 49. The pin A is then slightly released, so that the disc 74 is rotated, and an arm 76 causes a device 85 to enter a recess 87 of the bolt 51. The piece 54 is held by the engagement of its projection 56 with a spring, which can be depressed by the pin A of the key to release the piece 54 to unlock the bolt. With the release of the bolt 50, the bolt 51 can be withdrawn by pressing with the bit of the key on the end 89 of a lever 88, causing a projection 100 of the rotated sleeve 31 of the handle 3 to engage with a pin 105 and withdraw a catch 90. The bolt 51 is made in two pieces, which can be moved longitudinally relative to one another by turning the handle 3 and causing pins 95 on the sleeve 31 to engage in recesses 96 in the parts of the bolt. The piece 90 is forced back into locking position by a spring 107 when the handle 3 is set free. The plate 24 is forced back into the closing position by a spring 48, after depressing the spring 46 to release the pin 45. The pins A and B of the key are operated by collars C and D on the shaft and handle of the key respectively.
