Title: Improvements in Photographic Shutters.
Inventor: THORNTON JOHN EDWARD
Filed: 1899-06-05
Granted: 1900-04-14
Abstract: 11,600. Thornton, J. E. June 5. Shutters.-Relates to various arrangements of shutters of the roller-blind type. Figs. 1 and 2 show the front and end views ot one arrangement. In this case there are two blind rollers, one of which contains the driving-spring. A timing-device, consisting of a bellows charged with air or other fluid, and enclosed in a casing K, has two projections k, k<1> attached to it. This bellows is pressed down by a spiral spring, and, on pressing the lever N from under the stop k, the stops descend ; the projection k strikes the end of a lever F<2>, which, through the link F<1>, releases the stop n of the blind roller, and allows the blind to run to its open position, where it is arrested by the stop n coming in contact with lever P. The stops k and k<1> descend at a speed regulated by the size or the outlet of the bellows, until they strike the ring P', which depresses the lever P and allows the shutter to close. In another arrangement, the shutter roller is released by hand, and starts the timing-device. In a third arrangement, the blind works from either end, being actuated by the longitudinal elasticity of a spiral spring, the end of which is shifted from one peg to another at the end of each exposure.

Title: Improvements in and relating to Workmen's Time Recording and Wage Computing Apparatus.
Inventor: GARRATT JAMES HENRY
Filed: 1899-09-12
Granted: 1900-07-21
Abstract: 18,427. Garratt, J. H. Sept. 12. Time-printing stamps for workmen's tell-tale clocks. A motor pin-wheel 8 lifts the lever 7 at intervals, say, of half an hour, and through the cord 6, bell crank 5, link 4, pawl 3, and ratchet 2, rotates the shaft c; the pawl-carrying lever 18 also advances the ratchet-wheel 17 tooth by tooth. A series of rocking frames e pivoted on a bar d carry type-wheels g, which the workmen to whom each wheel is allotted can engage with the shaft c in the following manner. n, n ... are a series of tumblers, into one of which each workman can insert a key and turn it round so as to briqg a slot opposite the nose m of a bell-crank lever k. The nose moves forwards into the slot and locks the tumbler, the key in this position being also locked against removal, and the corresponding rocking frame e drops, with the other end of the lever, so as to bring the type-wheel g into gear with a wheel on the spindle c. At specified intervals, determined by a special arrangement of teeth on the wheels 19, 29, some of which are adjustable to allow for different times of commencing work, for overtime, and for short time on Saturdays, the wheel 29 receives a one-tooth movement, lifts the pawl 30, lever 31, and rod 32 and causes another motor to give a partial rotation to the pin-wheel 11. The lever 12 is thus actuated, and through a cord 13, lever 14, and universal bar 15 sets free all the levers k from the tumblers, and forces up the rockers e so that the type-wheels are thrown out of engagement. The record of work is printed by opening the door of the apparatus, and pressing down the buttons 37. The tumblers n may then be returned and the keys removed. The wheel 29 makes one revolution in a week. To allow of an inspector freeing any tumbler and taking an imprint at other times than those appointed, a second keyhole and a push mechanism actuated by its key are provided in the tumbler. The timerecording wheels g can be zeroized and cleaned at the same time by a rotary brush 36, and they print the time of each workman's attendance, as well as the amount of wages due to him for that time.

Patent GB-190012964-A (GB)
Title: Improvements in or relating to Conveyor Apparatus.
Inventor: BAKER GEORGE SAMUEL
Filed: 1900-07-18
Granted: 1901-07-13
Abstract: 12,964. Baker, G. S. July 18. Conveyers.-Relates to apparatus for automatically transferring trays &c. from one endless conveyer to two or more similar ones alternately. In the example shown in Figs. 1 and 2, trays H of biscuits from a cutting-machine are delivered to the transferring- apparatus by chains F<3>, and then alternately transferred to the two parallel oven conveyers G<1> and G<2>. The transferring-apparatus consists of two short endless conveyers D' and E<1> mounted on the top of a frame A and registering with the conveyers F<3>, G', and G<2>. At an angle a frame J<1> is fitted across the frame A, and in it are mounted two short endless chains, to which is attached a finger L by studs J<2>. The two chains are driven continuously by bevel gearing K, K from the shaft F. The gearing is such that the chains make a complete circuit during the arriva of two trays, and, as on the outward stroke the finger L is raised out of the way of the trays, it results that the latter alternately pass straight across to the conveyer G<2> and transversely to the conveyer D<1>, according as the finger L engages or not. The conveyers D<1> and E<1> are fitted at intervals with regulating upward projections D<2> and E<2>, so that each tray with which the finger L engages is pushed across from between one pair of projections to another. Fig. 5 shows another method of operating the finger L<1>. In this case it is mounted on one end of a bell-crank lever N<4>, to the other end of which a weighted pivoted lever N' is attached. These rods are carried by a block N, which is reciprocated on the guide N' by an oscillating radius arm M<9> and link M<10>. Stops N<5> alternately throw the lever N<2> and weight on to opposite sides of the vertical, and thus alternately raise and lower the finger L' as required. In another modification, neither of the delivery conveyers are in line with the receiving-conveyer, so that two fingers worked by screws are employed to push the trays alternately to the right and to the left ; or an oscillating pair of arms may be employed for the same purpose.
Patent GB-190013719-A (GB)
Title: Improvements in Machines for Cutting the Teeth of Gear Wheels.
Inventor: BILGRAM HUGO
IPC: B23F5/14
Filed: 1900-07-31
Granted: 1900-09-01
Abstract: 13,719. Bilgram, H. July 31. Shaping.-The operation of the machine described for cutting spur or spiral wheels is based on the fact that any number of gear-wheels gearing correctly with a rack, the teeth of which have the shape of a truncated V, will gear correctly with one another. In the present case a shaping-tool has this truncated V-shape, and operates on successive teeth during successive strokes, the blank, in addition to its rotary spacing movement, having a small rotary movement dependent on a lateral feed given to the tool slide, the effect on successive cuts being indicated in Fig. 8. The tool 8 is carried by a ram 6 reciprocated from a driving-shaft by a crank disc 14, rock-shaft 11, and rod 9. The ram slides on a slide 5, vertically adjustable on a bracket 4, which can be fed along the table 2. At the end of each cutting stroke, which is the pulling stroke of the rod 9, a shaft 26, with a long pinion 27, is operated from the driving - shaft to raise a rack 28, Fig. 7, with a cam surface a, causing the tool-holder 7 and tool to be lifted during the idle stroke. The mandrel 52, carrying the blank 53, is rotatably mounted in a bracket 54, swivelling on a pin 55, the mandrel axis being suitably inclined to the ram when cutting spiral wheels. A spacing movement is imparted to the mandrel during each idle stroke by worm, bevel, and spur gearing, including a segment 31 on the driving-shaft, a wheel 32 on a shaft 33, and shafts 40, 44 carrying changewheels, connected by an idler 43, the shaft 44 being connected by gearing to the mandrel. Each rotation of the segment causes the wheel 32 to make one revolution, which is communicated to the shaft 40 by a train of differential gearing, Fig. 5, comprising a bevelwheel 34 fixed on the shaft 33, a spur and bevel wheel 36 and a spurwheel 35 both loose on the shaft, and a pair of bevel pinions 37, carried in the web of the wheel 35. The wheel 36 gears with a wheel on the shaft 40. The shaft 44 is connected by belt gearing to a screw 58 for effecting the lateral feed of the tool, and this screw is connected by change gearing to a shaft 61 carrying a wheel gearing with the wheel 35. By this arrangement the cross feed of the tool imparts to the blank a suitable small rotary movement in addition to its spacing movement. The tool is adjusted so that its first stroke just cuts. the blank, and will then operate on successive spaces till it again reaches the first space, when it will take a deeper cut. In cutting a spiral wheel, the blank is set at the required angle, and the tool set to cut at the front face of the blank, successive cycles of cuts causing the tool to gradually cut further back as shown in Fig. 10, till it cuts at the back face and finally produces a practically-uninterrupted curvature of the faces of the teeth.

Title: Improvements in Machinery for the Manufacture of Paper or Cardboard Boxes
Filed: 1900-10-19
Granted: 1901-10-19
Abstract: 18,665. Lever Bros. and Phillips, J. F. Oct. 19. Stapling and like wirestitching. - Prepared paper or cardboard blanks are automatically folded and wire-stitched by apparatus of which one kind is shown in Fig. 1. The blanks are piled on an inclined table h having vertical rods or guides in front, against which the blanks rest, the front portions of the blanks projecting slightly beyond the table. A catch d<4> which holds the blanks being automatically removed, a movable suction device f engages with the front portion of the lower blank, and brings its end to the surface of a roller b<3>, which carries grippers by which the end of the blank is gripped to it. On the rotation of the roller b<3> the blank is fed between this roller and a roller C. At this stage the grippers are released and the blank is finally fed to a pivoted rising and falling table i. This table carries folders k, Fig. 3, by which, when the table rises, the blank is fed round a mandrel j, and the flaps or edges at the top are caused to overlap, as shown in Fig. 15. When thus folded, two wire-stitches are inserted by stitching-mechanism w overhead which is of ordinary construction. In case more stitches are needed, the box is automatically moved along the mandrel by a pivoted rod s' so as to bring it into position under another stitching-device, and, when completely stitched, the rod s' finally throws it off the mandrel. The clinching of the stitches or staples is effected by pivoted clinchers operated by a sliding rising-bar within the mandrel, having pins which move in inclined slits in the casing. In modifications the table i is dispensed with, the blanks being fed by bands to a vertically-moving table having side flanges which fold the blanks to the sides of the mandrel, the top folds being made by folders at the top ; the inclined table h is replaced by a frame which rests at an angle of 45‹, the bottom blank resting on side strips ; and the fixed mandrel is replaced by, say, four, mounted on a vertical shaft which is rotated intermittently to bring the box under the various stitching-devices, being held in the operative positions of the latter by a device similar to a Geneva stop.
