Abstract: 18,658. Chimkevitch, P. de. Oct. 18. Electrically-controlled fastenings. - Relates to electric apparatus in which anyone of a series of apparatus can be operated electrically without the interference of the others. The apparatus is described as applicable on wire or wireless circuits, and can be employed as a telegraph system, a telegraph call, a signal between ships &c.. for steering torpedoes or exploding mines, for connections between forts, for signalling between railway trains nnd trains and cabins, for operating signals, and also for controlling one of a number of door fastenings from a central position. Fig. 5 shows a view of the transmitter, in which a contact-disc 36 driven by clockwork is provided with a number of pins 38, which are cut down to half cylinders so as to make contact with spring 41, or to allow the said spring to pass according to the position of the studs. A second permanent contact-spring rubs on the periphery of the disc. A detent lever 29, with pawls 32, 35, is connected to the armature of the starting-magnet 24, and the lever 29 also carries a stop-arm 28 for the clockwork. The selecting-receiver is of similar construction, excepting in the contact-disc, and in that the magnet armature has an extension which, on the receipt of each impulse, trips a contact-spring. The contactdisc is double, the larger disc 44 having a number of studs 45 on which are mounted sleeves 47 carrying contact-springs 48, operating arms 49 and detent-lugs 53. The sleeves are provided with springs which normally throw the contact-springs outward against the pins 46, and the contacts are held in their closed or inner position by means of leaf-springs 51 having perforations in which the lugs 53 engage. The smaller disc carries a number of contact-plates, some of which are connected to studs and some of which have no contact ; in the latter case the stud is connected to the pin 46. Each arrangement is different, so that the circuit at only one receiving-station is completed. The receiver is provided with a tripping-stop, by which each spring 51 is tripped before reaching the position of the armature. On the completion of any selective signal, a local circuit is closed which either operates the required signal or mechanism or closes a local relay circuit, cutting out the selective mechanism aud connecting up the telegraphic or other signalling-apparatus with the line or coherer circuit in the case of wireless signalling.

Title: A New or Improved Machine for Trimming, Forming, Burnishing and Finishing the Edges of Leather Belting and the like.
Inventor: WRIGHT DAVID
Filed: 1901-12-27
Granted: 1902-02-20
Abstract: 26,433. Wright, D. Dec. 27. Belts and bands.-Relates to machines for trimming, forming, burnishing, and finishing the edges of leather belting and the like. The machine is shown in front elevation in Fig. 1, and in vertical section from front to rear in Fig. 3. The standards A are united by bridge-pieces B, B<1>, which constitute guides for the vertical slide C and the horizontal slide D, which are caused to traverse the bridge-pieces by the screwed shafts G, H respectively. The shafts are connected by the gearing L, M and shaft F so that their movements are always identical. The bridge-pieces also carry fixed plates E, F. The plate F and slide D support brackets Q, R, which can yield slightly in the vertical direction against the tension of springs U, V. In the brackets are formed bearings for the shafts W, X of the cutters 20, 21 which trim the edges of the belt, and also bearings for the trunnions of the upper belt-supporting and guiding roller Y. The trunnions of the lower belt-supporting roller Z are journalled in blocks 1, 2 carried by the plate F and slide D. The upper ends of the shafts W, X are carried in bearings formed on the plate E and slide C. The cutter shafts are driven by bevel gearing from the splined shaft 3. A portion of the periphery of the roller Z, Figs. 5 and 6, is adapted to gear with the pinion 13 on the shaft 14, the teeth forming a roughened surface which readily grips the lower or flesh side of the belting. The recesses 25, Fig. 6, enable the cutters to be brought very close together when operating a narrow belting. To enable the roller Z to be disengaged from the pinion 13 or removed from its bearings, a portion 26 is made removable, so that the teeth of the wheel 13 can pass out through the opening made by its removal. The cutters are shown in plan and vertical section in Figs. 8 and 7, and Fig. 9 shows a section of the belt 31 as it leaves them. The finished section shown in Fig. 10 is produced by the action on the trimmed edges of two pairs of burnishing-discs or edge rubbers 27x, 28x, Fig.3. The burnishers may be of agate, glass, lignum vitµ, boxwood, &c. They are mounted on vertical shafts 34, 35, of which the left-band pair is supported in adjustable bearings carried by the slides D, C, and the right-hand pair in adjustable bearings carried by the plates F, E. The burnisher shafts are driven by toothed gearing 59, 60, 61, &c. At the rear of the machine are guide-rollers 64, 65, of which the upper one is tensioned downwards by springs 66. Guides 70 support the belt where it is introduced into the machine. The traversing- slides C, D enable belting of any desired width to be treated. The shafts of the cutters, burnishers, and guide-rollers may be horizontal, instead of vertical, in which case the belt passes through the machine on its edge.

Granted: 1903-05-21
Abstract: 15,053. Witcombe, J. G. July 5. Battledores or racquets used in playing ping-pong, table tennis, or other games are constructed with expansible frames, so that the vellum, parchment, or the like which forms the striking-face, can be readily tightened up. The frame is made up of two pieces 1, Fig. 1, of wood, having raised edges 2 for the attachment of the vellum ; between the pieces 1 a wedge-shaped piece 4 is placed, which is connected by a screw 6, Fig. 2, to the handle 7 by means of the screwed sleeve 8. A collar 10, screwed on the sleeve 8, is connected by four metal or other straps 11 to the pieces 1, so that, on turning the handle in the proper direction relatively to the head, the parts of the head will be drawn down on the wedge 4, thus stretching the vellum. The extent of the movement of the pieces 1 is limited by a slotted strap 12, as shown. The collar 10 may be locked against a projection on the sleeve 8 by a milled nut 16. In a modification, Fig. 4, a downwardly-tapering wedge is used to force apart the two sides of the frame, the wedge being connected by a pair of nuts 6<a> to a screw 6, which screws into a nut 17<a> secured on the handle. The wedge slides against bearing- strips attached to the two parts of the head, and the upper parts of the wedge are fitted with metal guides 18, which prevent the displacement of the wedge. Slots and tongues or studs may, however, be used. The upper and lower extremities of the raised edges are embraced by metal plates 19, and a band 20 of leather or other flexible material is placed round the periphery, to prevent the puckering of the vellum which is attached to the band 20. In another modification, the sides are spread apart by an arrangement of toggles connected to nuts worked by a right and left hand screw carried by the handle.

Abstract: 26,329. Bamford, J. Nov. 29. Screening roots.-Relates to apparatus for cleaning swedes, turnips, mangold wurzels, carrots, beet-root, &c., and for feeding them to a receptacle or to a cutting or pulping machine. It is described in connection with a root pulper. On a continuation of the shaft of the pulper is mounted a roller B connected by a chain and sprocket-wheels, or equivalent means, with a similar and parallel roller A, which is driven in the same direction. The rollers consist of two circular end plates connected by longitudinal round or flat bars a<3>. They are covered by a cage G' which forms a continuation of a hopper into which the roots are thrown. As the root pulper is turned, the rollers cause the roots to rub against one another and loosen the dirt, which drops through the rollers while the roots pass on to the pulper. Wire or other brushes may be fixed on the rollers as at H<1>, H<2> and on the cage as at l<1>, l<2>, and they may be made adjustable as at H<5>, H<6>. The rollers may slope downwards towards the pulper and then may be plain, grooved, ribbed, or otherwise roughened, or they may consist of cores with a series of discs mounted upon them or with projecting pegs or a spiral screw. In one modification, three or four rollers are used and in another a single roller is placed at the side of the pulper instead of at the back and is driven from a countershaft by bevel gearing. In the modification shown in Fig. 7, the rollers are replaced by a moving inclined endless band or chain P, with projecting cross-bars p<1>, mounted on rollers or pulleys Q', Q<2>, the shaft q<1> of the pulley Q<1> being a continuation of the shaft of the pulper or driven therefrom by an universal joint. The cross-bars may have projecting wires or bristles, or a plain leather or other band or bands may be used. The Provisional Specification states that the bars of the rollers may be spirally twisted and that a series of small rollers may be placed cross-wise of the feeding trough.
