Granted: 1902-12-11
Abstract: 16,404. Easdown, R. H. July 23. Buckles for mail bags &c. One end of a strap x is secured to a locking-plate a, to which is pivoted a catch- a<2> having a bevelled projection sliding in an aperture a<1> in the plate. A seal box b, having check plates and a circular perforation b<2>, is con- nected by a looped-hinge c to the plate a, and a plate d adapted to fold over and lie within the box b, is hinged to the box. A disc e is mounted on the plate d, and has secured to it, so as to extend through the plate d, a tongue or hasp f provided with a notch k. A paper, parchment, or celluloid &c. strip or seal is placed in the box b, and the plate d is closed so as to retain the same. The strap x is passed through the loop c and tightened around the bag &c. to be secured and the box b is turned down, the tongue f passing through a hole in the strap and entering the aperture a<1> in the plate a. The strain on the strap brings the notch k into engagement with the plate a and the end of the tongue comes into contact with the catch and turns it into the position shown by dotted lines in Fig. 4, so as partially to cover the aperture and thereby secure the parts in position. In order to release the fastening, it is necessary to turn the disc e through half a turn to reverse the position of the notch and push back the catch a'. This can only be done by perforating the seal so as to expose holes h made in the disc e for the engagement of a key.

Granted: 1903-11-05
Abstract: 591. Rosenheim, C. Jan. 9. Window opening and closing apparatus.-Two ratchet-wheels 10, 9, of which the wheel 10 has twice as m a n y teeth as the wheel 9, are rigidly connected together and run loosely on the spindle 11. They gear, respectively, with the pawl 13 carried by the arm 12 and the pawl 7 fixed to the spindle 3, which carries the hook 4. On pulling the cord 15, the lever 14 is raised, and with it the lever 12, both levers being rigidly attached to spindle 11. The ratchet-wheel 10, being turned through the space of one tooth, causes the pawl 7 and therefore also the hook 4 to rise, and thus unfastens the window, which is pressed open by the lever 20 actuated by the spring 21. The hook 4 is retained in its raised position by means of a notch 25 in the pawl 7. To close the window, the cord 15 is again pulled, but the lever 14 is now prevented from rising by the projection 23 on the lever 20. The window is therefore raised bodily till the lever 20 strikes against the framing 6 and is turned into a position parallel to the frame. The lever 14 then rises, the hook 4 being thereby again raised to fasten the window. Springs 8, 16 are attached to the spindles 3, 11, respectively, to ensure the proper motion of the pawls, and stops 18, 18<a> are provided on the lever 14 to restrict its motion. The lever 20 need not be directly connected to the fastening-apparatus.

Granted: 1906-05-22
Abstract: 10,675. Lake, H. H., [Lovenetzsky, A.]. May 22. Hot-air engines.-In the engine shown in Fig. 1, all mechanical means for operating the displacer are dispensed with, its upward movement being effected by the pressure exerted on its lower end while the downward movement is effected by gravity. When the piston of the motor cylinder uncovers the port 2, air is admitted to the cylinder and is forced into the displacer-chamber 4, 5 through the port 3 on the return stroke of the piston. During the upstroke of the motor piston, the air in the lower part of the displacer-chamber is heated by contact with the walls of the chamber 5 and displacer 14 which are heated by a furnace 8. As the tension of the air in the chamber 5 increases, the displacer rises and 'forces the cold air in the water-cooled chamber 4 into the heating chamber 5, the expanded air is admitted through the port 3 to operate the motor piston. The travel of the displacer may be adjusted, to govern the speed of the engine, by regulating the position of the collar 20 on the guide-rod 16.
