Title: Improvements in the Mechanism of Brakes for Railway Wagons and other Vehicles
Inventor: LAYCOCK WILLIAM SAMUEL
Filed: 1902-08-12
Granted: 1903-06-25
Abstract: 17,662. Laycock, W. S. Aug. 12. Brakes.-In an either-side railway-wagon brake, the brake shoes are connected by push-rods F, F to a lever E mounted loosely between fixed collars on the ordinary transverse shaft C, to which are fixed the usual hand-levers A. The upper end of the lever E is connected by an adjustable rod I to an arm J on a short shaft K mounted in a bracket L, and another arm M on the shaft K is formed as a cam and is arranged to be engaged by a nose N pivoted to the lever A and limited in its motion by suitable stops. Depressing the lever A forces the nose N against the arm M, and puts on the brakes. On lifting the lever A again, the nose N turns on its pivot, and allows the lever A to be lifted easily. A stud may be fixed to the lever A to engage the back of the arm M and take off the brakes. Any suitable means may be used for holding the lever A in its raised position. If a quicker action is required, the nose N may be pivoted to a block which slides on the lever A and is connected by a link to a stud on the hanger D nearer than the shaft C to the lever M.

Filed: 1902-11-04
Granted: 1903-01-08
Abstract: 24,151. Lake, H. H., [Economic Machine Co.]. Nov. 4. Stopping-apparatus; cylinder machines with plane printing-surfaces.-Relates to the class of stopmotions for printing-presses and other machines, in which the part which shifts the driving-belt, trips the impression cylinder, or applies the brake, is held out of action by an electricallyreleased latch. Fig. 1 shows the feed end of a cylinder printing-press, and Figs. 2 and 6 show the stop-motion. The sheets are fed from the table A<1> to the cylinder A<2>. The press is provided with a footboard A', with foot-spindles A', A<6>, for applying the brake and tripping the cylinder, respectively, and with a band-lever A<4> for shifting the belt. The stop-motions are mounted adjustably on a frame C, which is provided with b earings for two shafts a, b. The shaft a is connected with the lever A' and brake spindle A<5> by arms and ro is a<1>, a<4>, and the shaft b is connected with the cylinder trip spindle A<6> by an arm b<1> and rod b<2>. Each shaft a, b is operated, when the stop-motion is released, by a spring or weight. In the Figures, an operating-weight G is shown, adjustable on an arm g pivoted at g<1> on a bracket adjustable on a vertical rod g<4>. The arm g is connected by a link g<6> to an arm H on the shaft a or b. The connection between the arm H and link g<6> is adjustable, to vary the angle they make with each other when in the locking position. This connection may consist of a pin on the end of the link g<6>, adjustable by screws h<2> in a slot in the end of the arm H. On each shaft a, b is an arm I pivoted at j<2> to the lower link J of a toggle, the upper link J' of which is pivoted at a fixed point j on the standard D or D'. The upper link J' is pivoted to the link J, and is formed with a socket j<3> in which the catch-bolt j<4> is arranged. The catch j<4> interlocks with a latch e, operated to release the catchbolt, and permit of the operation of the shaft a or b by an electromagnet e' and armature e<2>. The magnets and armatures are in boxes E E<1> secured to the standards D, D'. When in the locked position, as shown in Fig. 6. the toggle is nearly straight and takes the greater part of the strain of the weight G from the latch. The magnet e of the mechanism for operating the shaft a is in circuit with a battery f and a two-sheet detector F, which acts, in a suitable known manner, to close the circuit when more than one sheet, or an abnormal thickness of material is fed, and thereby stop the machine. The magnets e' of the mechanisms controlling both shafts a, b are in circuit with the battery f and a no sheet detector F<1>, so that the cylinder is tripped and the machine stopped when no sheet is fed. The toggles are returned to the locked position by bell-crank levers K operated by foot-spindles K<2> raised by springs m. The lower arms of the levers k engage rolers l<1> on the links J'. The shafts a, b may be operated by spring-pressed rods applied to arms, such as H, on the shafts, in place of the links g and weights.

Abstract: 11,921. Ferranti, S. Z. de. May 25. Welding; working by electricity.-To facilitate the welding of turbine vanes to their discs or wheels, the volume of metal in the wheel is reduced near the vanes to enable the wheel and vane to be raised more easily to the same temperature at the weld. The reduction may be effected in various ways, such as by forming circumferential, diagonal, or cross grooves in the wheel, leaving rings or projections to which the vanes are welded; or holes may be drilled radially in the periphery or in the face of the wheel near the periphery. The wheel may be built up of two or three dished discs k, m, spaced near their circumferences by distance-rings l, the vanes d being welded to the edges of the discs. In the case of three discs being used, a part n of the hub is removable to allow the parts to be assembled. When two discs are used, they may be brought together at their circumferences and notched to leave projections to which the vanes are welded. The wheel may be built up of a number of flat notched discs, the notches being " staggered " to leave projecting ribs corresponding to the shape of the vanes; or the laminated wheel may be treated in any of the ways described.

Granted: 1904-08-25
Abstract: 22,986. Seguin, L. L. A., and Sales, J. F. G. de R. de. Oct. 23. India-rubber substitutes.-An artificial caoutchouc is formed by allowing the ferment from virgin caoutchouc to react with coal tar. The raw caoutchouc, cut into small pieces, is dissolved in benzine, and exposed to daylight in a closed vessel, being shaken from time to time, until a deposit forms and the benzine separates on the surface, when the whole is heated at 50‹ C. until it becomes red and the deposit dissolves. The solution is poured into about double its volume of alcohol, and a certain quantity of the precipitate formed is spread over coal tar and boracic acid in a closed vessel, which is then heated to 50‹ C. in a current of oxygen. The ferment dust collected on the walls is added to an intimate mixture of 10 kilogs. of tar and 1 kilog. of boracic acid, with a little alcohol, and fermentation is allowed to proceed for about 15 days at 60‹ C. in a current of oxygen free from nitrogen. Hydriodic or phosphoric acid may be used instead of boracic acid.

Granted: 1904-12-22
Abstract: 23,098. Gõrtner, F. Oct. 26. Producing photo-reliefs.-A process for producing relief photographs consists in first obtaining a positive on a sheet of porous unsized paper, then backing this with a coating of glue and a thin layer of glaziers' putty, and finally modelling the picture from the front. The porous unsized paper is sensitized with potassium bichromate and silver nitrate, and on this an impression is printed from the negative and subsequently toned with platinum. The sheet, when wet, is secured by glue at its edges to a frame so as to dry smooth and stretched. A coating of glue is painted over the back and then a thin layer of putty is put on, and this is dusted over with some powder. The modelling is then carried out from the other side and the whole allowed to harden. Wax may be used as a backing, but, if so, it must be removed after the modelling, and the impressions in the porous sheet filled in with a hardening compound. Having obtained this relief impression, a mould may be obtained and copies then reproduced in gypsum, metal, &c.

Abstract: 25,988. Schlosser, R. J., Fisher, H. R., and Piso Co. Nov. 29. Corking.-In the corking-machine shown in Figs. 1 and 2, the operations of feeding the bottles to the corking- plungers 33, and supplying, feeding, and inserting the corks, are all effected automatically by the movement of two vertically-reciprocating rods 30, which are operated by cam-grooves 9 on a pair of eccentric discs 8 driven by a hand-crank 10 or by power. The corking-plungers,of which one or more may be employed, are carried by a cross-bar 34 connected to the upper ends of the rods 30. The lower ends of the plungers are screwed to receive heads 36, which are interchangeable to suit corks of different sizes. The bottles are placed on the table 12, and are fed forwards to the plungers by the hooked pawl 14 engaging the rack 13 on the underside of the table. The pawl is slotted to receive the guide-bolts 17, and is connected by links 19 to levers 22 operated by pins 31 on the rods 30. To enable the feed to be varied as required, the lever arms 22 are slotted and provided with adjustable blocks 24 for varying the throw imparted through the links 19 to the pawl. The corks are supplied from the hopper 53 through tubes 37 to apertures 39 in the feed-plate 38, which is mounted on a cork-guiding plate 45 supported on pivoted links 46. The plate 45 is provided with cork-guiding openings 49, etch fitted with a felt washer 50, which is coated with a suitable lubricant to facilitate the passage of the cork. The feed-plate 38 is reciprocated by a lever arm 40, which is toothed at its end 41 to gear with a rack on one of the rods 30. The arm 40 also reciprocates the guide-plate 45, by engaging with studs thereon. The plate 38 is first moved to bring the apertures into alignment, and both plates then move together to bring the corks over the bottles. The hopper 53 is provided with an inclined shoot 60, and with a vibrating plate 55, Fig. 4, to supply the corks to the tubes 37. The plate 55 is vibrated by means of the arm 57, which is actuated by teeth 59 on the rods 30. In some cases, the cork-supplying and cork-feeding mechanisms may be dispensed with, and a separate cork-guiding plate, formed with a series of rows of apertures, employed. Each aperture is provided with a lubricated felt washer, and the plate is placed upon and fed forwards with the bottles, which are placed in rows corresponding with the openings in the plate. Fig. 8 shows a modified cork-supplying mechanism, in which the corks pass from the hopper 67 through apertures 69 in the agitating-plate 68, and through apertures 71 in the fixed plate 70, into apertures 72 in the reciprocating feed-plate 73, which conveys them to the apertures 75 communicating with the supply tubes 37. The plates 68, 73 are suitably actuated from the rods 30.
