Title: Automatic Coin-freed Latch Lock.
Inventor: BODNAR FRANZ XAVER
Filed: 1898-05-28
Granted: 1898-08-06
Abstract: 12,130. Bodnar, F. X. May 28. Fastenings, coin-freed, for doors and the like. The fastening on the door b is contained within a thin casing a, itself within a box c which forms a receptacle for the money M, and is accessible through a lock d. A spring latch o' pivoted on the outside of the casing a and passing through a guiding-eye n, engages a fixed hook r when the door is closed. A coin inserted at a slot e drops into a recess k in a plate f, which can be pushed down by a.handle g. In this movement the coin thrusts back a lever v, and the latter, having a pin-and-slot engagement with the latch, disengages it from the hook r. At the same time a pin E on the sliding plate lifts a catch z to a pin y on the lever, so that the latch cannot rebound when the coin has dropped away. The friction of the hook r upon the latch as the door is opened shakes the catch z free again, so that the parts return to the initial positions. Behind the recess in the sliding plate there is an aperture m in the casing a, and the coin is shot through this aperture after escaping from a retaining-finger l.

Granted: 1899-11-18
Abstract: 24,399. Lake, H. H., [Miller, T. S.]. Nov. 18. Rope railways and tramways. -Relates to improvements on the invention described in Specification No. 16,832, A.D. 1898. A represents the ship being coaled, B the collier, and C a tow-rope connecting the two. The overhead transmitting-rope passes from the drum of a motor E around pulleys 2, 4, 6, and 7 in succession to a second motor F. The two motors are driven in opposition, but, since E is the more powerful, it effects the transit of the load, while the second or resistance motor F keeps up a constant tension on the rope, notwithstanding any lurching that may take place. The return of the empty carriage D is effected by paying out the rope a b from the motor E, thus allowing the resistance motor F to wind it in. This motor F may be replaced by a sea anchor such as that shown in Figs. 8 and 9. A conical bag 20 is attached to a rod 26 carrying arms 24 which slide on a frame 29 attached to the rope 1. A spring 31 is interposed between the arms 24 and the end 28 of the frame 29. The arms 24 are also connected by links 25 to a collapsable disc 21 attached at the centre to the rope 1. Should any increase of resistance occur to the passage of the anchor through the water, the spring 31 compresses and the disc 21 folds up to decrease the resistance as shown in Fig. 9.

Title: Improvements relating to the Manufacture of Felt Hats.
Inventor: TIRARD CLEMENT MARIE
Filed: 1901-05-01
Granted: 1902-04-24
Abstract: 8990. Tirard, C. M. May 1. Felt hats.-Relates to felt-hat finishing-machines. Fig. 6 shows in section the polishing-pad and its associated parts. The glass paper or the like 11 is held by flat springs 25 on a sheet of felt which rests on a support 10 rigidly connected to a plate 12 mounted on two eccentrics 13, 14, the axes of which have on them pinions 19, 20 connected by a pinion 21 and driven by an electromotor 24, or other means mounted in a chamber 18. The effect of this arrangement is that a vibratory motion in one plane is imparted to the pad, or in other words each point of the pad describes a circle. The pad &c. is pivoted in a frame, and is balanced by a counterweight 42. Fig. 4 shows a side elevation of the whole machine at the termination of the finishing operation, the pad having automatically been thrown out of contact with the hat 1. To bring the pad into operation, it is raised by the handle 27, so that part of the frame is caused to engage with the pawl 39, and the pad is then traversed over the surface of the hat, which is itself mounted upon an oval chuck. Fig. 1 shows a plan view of the machine at the moment of the commencement of the finishing process. The traverse of the hat pad is effected as follows :-The shaft 33 is mounted in a fork 43 rigidly connected with a plate 44 mounted in a socket 45 and having fixed upon it another plate 46, to which is attached a connecting-rod 47, the other end of which is journalled upon a toothed-wheel 48. The motion of this connecting-rod causes the pad 11 to move over the hat. The wheel 48 is mounted loosely on a hub 49, which is in turn mounted on a shaft 50 eccentric to the wheel 48. By moving a handle 51 attached to the hub 49, the wheel 48 is made to gear with the wheel 61, and is thereby set in motion and continues in motion until a projection 54 on the wheel 48 depresses a spring 52, and thereby releases the handle 51, which has been held in a notch in the spring, and the hub 49 accordingly turns and moves the wheel 48 out of gear with the wheel 61. At the same time a stud 57 on the connecting-rod 47 bears against a sector 58, one end of which presses against the arm 38, and thereby releases the pawl 39, allowing the pad to fall back to the position shown in Fig. 4. At the same time the electromotor 24 is stopped by an interruptor which automatically closes the circuit when the machine is started and opens it when the machine is stopped.

Title: Improvements in the Manufacture of Alumina.
Inventor: HALL CHARLES MARTIN
Filed: 1902-01-28
Granted: 1902-03-13
Abstract: 2260. Hall, C. M. Jan. 28. Electric furnaces.-An arc furnace is used for obtaining pure alumina from bauxite or the like, by the method described in Specification No. 14,572, A.D. 1900. A circular carbon block 2 forms the base and one electrode, one or more hanging carbon rods 3 forming the other electrode. Two concentric sheet-iron shells 4, 5 are placed upon the base, the annular space 6 thus formed being charged with a mixture of the crude bauxite and carbon. Fusion is started in the interior of the inner shell by bringing the hanging electrodes into contact with the carbon base, turning on the current, slightly raising the hanging electrodes to form an arc, and piling around them the mixture resulting from a former operation in the outer space. The shells are preferably perforated. As the process continues, more and more of the treated bauxite is added until as much material has been fused as the inner space can safely hold. The current is then stopped, the hanging electrodes withdrawn, and the furnace allowed to cool for days or even for two or three weeks before being broken up. The heat of the fused material in the centre is largely communicated to that in the outer annular space, causing it to undergo incipient fusion.
