Title: Improvements in Raising and Lowering Apparatus applicable for Fire Escapes and other purposes.
Inventor: LANSING EDWIN
Filed: 1903-06-03
Granted: 1904-04-28
Abstract: 12,535. Lansing, E., and Burch, E. F. June 3. Hauling and winding drums; balancing-devices; winches.-In lowering apparatus, applicable as a fire-escape, the rope is automatically re-wound on the drum A, by a spring F, connected at G to the fixed spindle E and at H to the drum A. The speed of the drum is regulated by a centrifugal governor J, acting on a brake and connected by gearing N to a toothed wheel M fixed to the toothed wheel K, which is rotated by a pawl as the rope is unwound. If desired, the wheel K may be fixed to the drum A, so that the governor acts in both directions. In a modification, two ropes are wound in opposite directions on the drum, so that, as one is unwound, the other is re-wound.

Title: Improvements in Fishing Reels.
Inventor: FUNK EDGAR MARION
Filed: 1903-06-11
Granted: 1903-07-16
Abstract: 13,135. Funk, E. M. June 11. Reels and winches, rod.-Relates to fishing-reels of the type in which the line spool may be wound automatically by a spring or readily changed to permit winding by hand. Figs. 1 and 3 show sectional elevations of a reel constructed according to the invention. Figs. 2 and 4 show sectional elevations along the lines 2 ... 2, 4 ... 4. The frame is fixed to the fishing-rod by the usual slip rings and the bars 10. The spindle 14 is secured to a sleeve 16 and is movable longitudinally, as shown in Figs. 1 and 3. On the spindle is mounted a spring barrel 19, 20, provided with a laterallyextended hub 21, the end portion being rectangular in form, to carry a ratchet-wheel 23, of the form shown in Fig. 4, or the modification, Fig. 11. The pawl 24 is thrown in or out by the taper end of the sleeve 16 acting on the rod 25. The spiral spring 30 is connected at its ends to the sleeve 18 and barrel 19. The flanged disc 19<1> is mounted loosely on the spindle, and carries pawls 32 engaging a ratchet-wheel 31, which is fixed to the spindle. When the spindle is placed as indicated in Fig. 3, the turning of the crank-bandle clockwise will cause the winding up of the spring, the pawl 24 preventing movement of the barrel 19, and the spool also remains at rest. The disc 19', on its flange 34, has formed an annular rack 35, the teeth meshing with those of the pinion 36 mounted on the loosely-hung arm 37. This pinion 36 is secured to the wheel 38, which gears with the pinion 39 formed on the inner face of the spool plate, which is loosely mounted on the spindle. The opposite plate, which is also loosely mounted, carries notches 46, Fig. 5, by which the spool is locked to the barrel, by means of the bolt 49 worked from the flange 16. When the parts are as shown in Fig. 1, the reel may be revolved freely in either direction. When wound, the spring may be made effective by drawing out the spindle as indicated in Fig. 3. A further outward movement unlocks the spring barrel and spool, the device then being capable of use as an automatic take-up for the line, the speed being regulated by grasping the operating-crank. The movement may be retarded or accelerated by turning the handle to the left or right. Figs. 7, 8 and 9, 10 show two modifications of the gearing at the crank side of the spring barrel.

Title: Improvements in or connected with Automatic Vacuum Brakes
Inventor: BROWN HARVEY EZRA
Filed: 1903-06-12
Granted: 1904-02-18
Abstract: 13,227. Brown, H. E. June 12. Brakes. - A threechambered valve for facilitating the rapid application of vacuum brakes in cases o f emergency is screwed into the train-pipe a, preferably at the end of each vehicle. The lower chamber c communicates with the train-pipe. The intermediate chamber d is open to the atmosphere through orifices f, and is separated from the upper chamber e by a diaphragm g. A valve h, secured to the diaphragm normally closes communication between the chambers c, d. This valve is mounted on a spindle j, and is held on its seating by a spring k, the tension of which can be adjusted by a nut. There is a leakage passage, connecting the chambers c, e between the valve and the spindle. When air is admitted to the train-pipe, the valve h is raised, and the train-pipe and chamber e placed in communication with the atmosphere. The spindle is flattened or grooved, so that, when the valve is lifted to its fullest extent, the passage between the chambers c, e is suddenly enlarged. The surfaces of the diaphragm g and valve h which are exposed to the atmosphere are of about the same area, the pressures on these thus balancing one another, and when the vacuum in the chamber e is reduced, the valve is closed by the spring k, so that the pressure of the brakes can be gradually reduced as the train slows down.

Title: Improvements in Millboard and like Machines with Work-checking and Cutting Devices.
Inventor: MIETASCHK OTTO
Filed: 1903-07-09
Granted: 1904-07-09
Abstract: 15,187. Mietaschk, O. July 9. Indicating thickness of sheets. -Millboard and like machines are fitted with apparatus for indicating automatically when the required thickness is attained, such apparatus being also arranged to liberate the cutting-knife. As the moist sheets of paper are wound on the machine cylinder, a roller d is lifted, and acts through a pivoted lever e to depress an adjustable arm f extending into a casing b, this movement being indicated on a dial l, and also, by means of a spring pencil s, on a strip of paper wrapped round a drum r<6>, which is rotated continuously by clockwork, so as to record the working of the machine. When the required thickness is attained, yielding or liquid contacts n, h complete an electric circuit, which rings a bell o. When the circuit is completed through the contacts n, h, a current passes through the electromagnet x, which then withdraws the projection w<2> and allows the lever w to fall and lift the pawl v, the pressure on these being eased by the lower roller y pressing the segments slightly inwards in the position shown. The circuit to the electromagnet is made by stationary brushes bearing on rings on the shaft S, one of such rings being made of vulcanite to which a copper strip is secured in the position for completing the circuit at the required time. The cutting-knife apparatus may be mechanically released by adjustable projections set to act when the millboard is the required thickness. Several sets of apparatus are applied to the cylinder when it is required to cut the millboard at several parts of the circumference of the cylinder. If the cutting-knife is disconnected and the machine is not attended to when the bell o is sounded, the continued action of the machine causes another contact g on the arm f to come against a contact m, completing a circuit to a bell p in the foreman's office and also indicating on a board q the machine in fault.

Granted: 1904-05-19
Abstract: 6601. Johnson, J. Y., [Drury, W. H.]. March 18. Yarns.-A core yarn is produced by spinning and laying fibrous material uniformly round a core of single or, preferably, doubled spun yarn, and is applicable for the manufacture of woven, knitted, or braided goods, and thread, twine, rope, or cordage. The machine described in Specifications No. 17,169, A.D. 1898, and No. 6602, A.D. 1904, may be employed, the core yarns being drawn diagonally across the rings of ring doffers of carding-engines, and then between the rubbing-faces of spinning- straps which cause them to revolve. The strips of fleece from the doffer-rings lap round the cores, and are spun in passing between the spinning-straps. The spun cores should preferably have a twist opposite to that imparted to the covering fibres. The shearings of wapped cloth and fibrillated leather, alone or mixed with other fibres, may be utilized as the covering-material on a strong spun core. Wool, cotton, cotton waste, silk noils, flax waste, asbestos, fibrous peat, &c. may be spun on a cotton core. A woven horse-blanket is made from yarn having a jute core round which wool is spun, and towelling of yarn having a cotton core with a linen covering.

Title: Improvements in Electric Motors.
Inventor: MCNEILL RALPH
Filed: 1904-04-26
Granted: 1904-06-09
Abstract: 9581. McNeill, R. April 26. Motors, alternating-current.-In an alternating- current electric motor of the commutator type, the rotary armature A, Fig.. 1, is provided with two or more independent circuits which are connected to alternate bars c, c or c', c<1> on the commutator so that each is always connected to a pair of brushes b, b or b<1>, b<1> but cannot be short-circuited by any of the brushes, thus obviating sparking. The circuits need not be entirely independent as shown in Fig. 1, any arrangement which preserves the electrical independence of the circuits between brushes of the same polarity being applicable. For example, the interconnected arrangement of three circuits shown in Fig. 6 may be employed. Any number of brush circuits may also be employed. The armature windings may be in series with the field windings F, F<1>, and are supplied with currents of the same phase, obtained, for example, by means of two similar secondaries s, s', Fig. 1, on a transformer C. Or the armature circuits may be energized independently of the fields, the field current having lead with regard to the armature currents to counteract the greater reactance of the field circuit and thus to produce synchronism of the armature and field magnetizations. Any suitable arrangements may be used for producing similar currents in the armature circuits and a leading current in the field circuit. The two arrangements of separate field and armature circuits and series-connected field and armature circuits may be combined in the one motor. This arrangement allows of the field and armature magnetizations being brought more nearly into phase than otherwise. A rheostat R, R', Fig. 1, choke coils, or a switch connected to taps in the secondaries s, s<1> may be provided for starting or speed-varying purposes. Fig. 4 illustrates a motor having the field wound with coils p, p<1> and s, s<1> which act as transformer primaries and secondaries respectively; parallel or series connections of similar coils on the two parts F, F<1> of the field magnet may be employed. It is stated that either the armature or the field magnets may be the rotary element of the motor.

Title: Improvements in Air Compressors.
Inventor: WEISS FRANZ JOSEF
Filed: 1904-05-10
Granted: 1904-12-08
Abstract: 10,795. Weiss, F. J. May 10. Compressing.-In direct-driven, high-speed, single or double acting air-compressors, piston-valve distribution is used, the system being suitable for small pressure ratios. Fig. 1 shows a doubleacting compressor with the valves k in their extreme left-hand position. The valves may be cushioned in chambers b. They have a small or even negative, outside lap and a large inside lap. They are set to open the delivery port when the air in front of the working-piston is approximately at the compression pressure, and to leave the suction port open for a part of the return stroke, thus ensuring full suction pressure in the cylinder. The cylinder diameter may be increased to compensate for the loss of working-volume due to the latter arrangement. Fig. 6 shows the arrangements for use with a differential piston in a compressor for stage compression. The distributing-valves k work in the same manner as in the first-described arrangement, but two extra pistons f, g are used, the former separating the compression chamber of the lower-stage compressor II from that of the higher one III, the suction chamber of which is closed by the piston g. The suction pressure of the compressor II is maintained on the left-hand side of the piston g by a pipe h, thus balancing the valve, or the ends of valve chamber may be left open. Zeuner and indicator diagrams are given showing the action of the valves.

Title: Improvements in Reapers and Binders.
Inventor: TEHAN MICHAEL JAMES
Filed: 1904-09-13
Granted: 1905-01-12
Abstract: 19,729. Tehan, M. J. Sept. 13. Reaping and harvesting machines.-Relates to a motor harvesting-machine provided with gearing to enable the machine to be propelled, and the cutting-apparatus and other moving parts to be driven, independently of each other. The sheafing and binding mechanism may be of any ordinary type. Fig. 3 shows the machine in plan. The main frame C consists of two circular parts 69, 70 connected by bars which support the binder frame M at one end, the other end of the frame M being supported by the wheel R. The frame M, which carries a complete set of cutting-apparatus at each side, may be tilted and secured in position by a suitable hand-lever. Platforms P, Q, supporting respectively the driving-wheel A and the steering- wheel B, are mounted, so as to be free to turn, in the circular parts 69, 70 of the main frame, respectively. The motor H is mounted on the platform P and drives the shaft I fitted with a flywheel G. The driving-wheel A is driven from the shaft I by an arrangement of change gearing by which it may be driven in either direction. The shaft I further drives the shaft J by means of the chain 12 and, if desired, variable-speed gearing. A shaft K is driven by bevel gearing from the shaft J and drives the two sets of cutting-apparatus by means of a crank disc and eccentric respectively. The disc and eccentric are connected by clutches to the shaft K so that either may be operated as required. The shaft K drives, by means of chain gearing, a shaft L which drives the packing and binding mechanism and also the conveyer rollers and the reel shaft. The reel 0 is supported in a bracket 44 from a standard 46 adjustably carried by a frame capable of sliding on transverse bars of the binder frame, so that the reel can be adjusted to act with either set of cutting-apparatus. Special driving-mechanism to operate in all positions of the reel is described. The Specification also describes a form of sheafcarrier, in which a number of curved bars are fixed to an oscillating frame, and a second series of curved bars are pivoted so as to co-act with the fixed bars. The pivoted bars are operated by a treadle and rope mechanism so as to close upon the fixed bars and securely hold the sheaves. The frame is then oscillated and the pivoted bars released, so that the sheaves are deposited upon the ground in the form of a stook.

Patent GB-190500842-A (GB)
Title: Improvements in or relating to the Manufacture of Knitted Goods and in the Means employed therein.
Inventor: SPIERS WILLIAM
Filed: 1905-01-16
Granted: 1905-09-14
Abstract: 842. Spiers, W. Jan. 16. Circular knitting-machines.-A complete welted sock, stocking, or other article is produced in a continuous process without any stopping or manipulation of the needles. The superposed cylinder type of machine can be used with double-ended latch needles, as described in Specification No. 15,008, A.D. 1900. The improvement consists in arranging the needles to knit a one-and-one rib welt, and in providing the bottom cylinder with both long and short butted sliders or jacks and a transferring-cam with arms of unequal width. By these means an automatic transference is effected from the welt to a two-and-two rib top. The spindle 9 of the cam 5 for the bottom cylinder passes through the cam carrier, and is provided exteriorly with projections 12 on a disk 11. These projections can be engaged by spring-pressed pins under the control of pivoted levers, which are rocked by stops on a ratchet-driven pattern disk. By bringing the broad arm 5<a> or the narrow arm 5<b>, respectively, of the cam 5 into the path of the sliders, all of the latter or only those having long butts can be actuated according to the transference of needles required. At the commencement of knitting, all the needles are in the bottom cylinder, as shown in Fig. 5. In the top cylinder, long and short sliders l, s alternate while in the bottom cylinders the sliders are arranged in twos. Every fourth slider in the top cylinder is removed and, in the bottom cylinder, is replaced by an ordinary non-transferring needle n. To produce the one-and-one rib welt, the narrow arm 5<b> of the cam 5 transfers the needles carried by the long-butted sliders l to the top cylinder, giving the arrangement shown in Fig. 6. A single course only is knitted, after which a welt cam places the top needles out of action, while a number of courses are made on the needles of the bottom cylinder. The transferring- cams of both cylinders then act simultaneously, to transfer the needles of the top sliders l to the bottom cylinder and the needles of the bottom sliders s to the top cylinder, giving the arrangement shown in Fig. 7 for knitting the two- and-two rib top. The stocking or other article is completed in a well-known manner. According to the Provisional Specification, sliders with three or more butts may in some cases be employed.
