Title: Improvements in Photographic Shutters
Inventor: MCKELLEN SAMUEL DUNSEITH
Filed: 1900-04-14
Granted: 1901-04-13
Abstract: 7009. McKellen, S. D. April 14. Shutters.-Relates to the use of an auxiliary shutter to close the lens opening while the main shutter is being set. The invention, as applied to a rollerblind shutter, is illustrated in Fig. 1. The main blind c is mounted in the usual way on rollers a and b, and the auxiliary blind f on rollers d and e. The winding-up cord g passes round a pulley m attached to the end of a cord k, which winds up the roller e, then passes down outside the shutter box, and up inside to a pulley on the end of the roller b. As a result of this arrangement, when the cord g is pulled, the blind f is first wound on the roller e, and covers the lens aperture. The continued pulling of the cord g then sets the main shutter by winding the blind c on the roller b. When the cord g is released, the blind f is wound back on to the spring roller d, till its aperture is again opposite the lens.

Granted: 1901-11-02
Abstract: 18,106. Rateau, A. C. E. Sept. 10. Centrifugal pumps.-Relates to multiple centrifugal pumps for high-pressure delivery. Fig. 6 shows a pump with two runners. The runners 1 are fixed on the same shaft, and the liquid passes through them in series. They are separated from each other by diaphragms, each consisting of two parts 5, 6 of such a shape that the passage between one runner and the next is U-shaped in diametral section. These passages are fitted with partitions 10 to check churning action. The diaphragms are an easy fit on the shaft, and are retained in place by grooves in the casing. The back 24 and front 23 of each runner are of different diameters, the difference in each case being calculated so as to balance the longitudinal thrust. The complete balance of this thrust is obtained by a piston 46 on the end of the shaft, one side of the piston being exposed to the delivery pressure and the other to that at some suitably-chosen point in the pump. Any number of runners may be mounted on a single shaft, the construction being similar to that described above ; or the runners may be arranged in two sets, each comprising several runners, or, as shown, one. The two sets are mounted on shafts 2, 32, respectively, having a clutch coupling which may form part of the piston 46. By means of the two deliveries 33, 34 and valves 37, 38, one set may be used alone for a low pressure or the two in series for a high pressure.

Abstract: 24,485. Hanneborg, 0. B. H. Dec. 2. Drain ploughs and trench excavators.-Relates to an excavating-machine of the kind in which the earth is excavated by means of a screw placed on a machine which runs on rigid rails and is driven by an engine through an endless rope. The machine is specially adapted for excavating old ditches, but it may be employed for cutting new ditches or trenches. The machine is shown in elevation in Fig. 1, and in plan in Fig. 2. The supporting- rails 302 are placed one on either side of the ditch or trench, and are carried on wooden or like supports. The screw digger, Fig 6, consists of a narrow cutter 104 arranged as a tapering spiral, and the loosened earth is collected by the plate 119 at the back of the cutter, falls through a hole in the plate on to the shoe 115, and is conveyed by the transporter 122, 123 and the endless bands 129, 130 to the sides of the ditch or trench. The shoe 115 is provided with the guiding-bar 116 and with the curved pieces 117, to prevent it from turning aside. The spiral cutter 104 is stayed by bars which are connected by means of the arms 107 with the hub 106 keyed on the axle 108. Of the three frames 1, 2, 3 of the machine, the intermediate frame 2 is connected by means of the bolts 202, 205 and bearings 204, 307 with the lower frame 3, so that the intermediate frame may swing and be operated from the seat 142 by the gear-wheel 173, the chains 171, the vertical axles 175, 207, the worm 206, and wheel segments 308 fitted to the frame 3. Motion can be transmitted to the axles 175, 207 independently of the raising and lowering of the upper frame 1. The actuating-mechanism for the upper frame 1 comprises the bevel-wheels 157, 159, 160, the wheels 159, 160 being connected by a sleeve controlled by handle from the seat 142, and the four pinions 155 engaging with the four vertical racks 203. The progressive motion of the machine is effected by means of the bevel gear-wheel 137 and the wheels 139, 140, each of which two wheels is loose on the axle 138, but can be made fast by the conical clutch 141 so as to transmit motion by suitable mechanism to the wheel axles 304 of the machine. The cutter is driven from the power wheel 101 by bevel gearing, and the handle 114 controls the gearing and the working of the cutter. The conveying-bands 129, 130 are actuated from the shaft 128, and the elevator 122 is worked from the shaft 126 of the power wheel 102. In working, the trench is marked out and the machine is guided by a weighted pointer 178 which hangs vertical, and on slopes the frame 1 may be placed horizontally by viewing a level placed on the platform of the machine. When the machine begins to excavate, the cutter or frame 1 is adjusted so high that the cutter shoe 115 only touches the ground, and the frame 1 is set slightly sloping by means of the hand-wheel 173. The cutter is set in rotation by the handle 114 and the machine in progressive motion by the handle 143.

Abstract: 24,823. Moir, G. Nov. 12. Undercutting &c.-Coal, fireclay, &c. are undercut &c. along the face A<1> by an endless chain carried by bogies which run into recesses B driven in advance. The face may be stripped while the undercutting proceeds. The bogies are constructed with side H girders 5 mounted on wheels. In one bogie the girders are extended to carry an electric or other motor 8, which drives the chain through spur gearing 15 and the worm gearing 18 in an oil box and sprocket-wheel 23 with a vertical spindle resting in a plummer block. The gearing and motor are carried by a slide mounted on the frame and fed by the screw 20. The feed is similarly arranged on the other bogie, which is provided with means for giving tension to the chain, but this may also be applied on the driving-bogie. For this purpose, the axles 7 are screw-threaded, and gear with internally-screwed sleeves 40 in the frame, both sleeves being turned by worm gearing 37 from the hand-wheel 41. The chain is made with detachable links each consisting of two sides with a round pin 31 at one end and a hook 32 at the other. The sides are notched at 33 so that the hook can be passed laterally on to the pin. Serrated cutters are bolted to lugs on the sides. To support the material as the cutting proceeds, " gibs " 35 are drawn into the cut by temporarily attaching them to the return side of the cutter chain.

Granted: 1904-04-14
Abstract: 11,769. Barron, T. H., [Northrop Loom Co.]. May 23. Looms, forming selvages in; shedding - motions; stop-motions.-A selvage shedding-motion is constructed and arranged so as to cause the planes of the selvage shed to be in alignment with the planes of the main shed. The invention is described as applied to a loom wherein warp stop-motion detector-healds are employed, but is applicable generally. The selvage detector-healds, at each side of the loom, are suspended from lateral projections m<4>, n' on the inner surfaces of metal bars m, n, which are reciprocated vertically, and are guided by their reduced ends m<3>, n<3> passing through slots g', g<3> in a block g, mounted on the transverse separator A<10>, which serves as a backstop for a released detector in connection with the warp stop-motion. The upper ends of the bars m, n are yieldingly connected by means of a spring s<x>, and a band 35 passing over a pulley 36, and projections m<2>, n<2> on the bars are connected by bands m<x>, n<x> to opposite sides of a drum a<4>, the band m<x> being guided by a pulley 20. The drum a' is adjustably secured to a stud 8 adjustably fixed to a pivoted lever a', which is oscillated by a grooved cam c<2> on a shaft C', so that a shedding-motion is transmitted through the bands m<x>, n<x> to the selvage healds supported by the bars m, n. The band m<x> is connected to the drum a' nearer to the fulcrum of the lever a<1> than the band n<x>, so that the front selvage healds receive less motion than the back selvage healds, and such differential motion is adjusted by changing the position of the drum a' to bring the planes of the selvage shed into alignment with the planes of the main shed. The healds of the main shed may be similarly operated. A released selvage detector engages and arrests one of two vibrating feelers, and thereby stops the loom, in the same manner as a released detector of the main shed.
