Title: Improvements in and relating to Gun Mountings
Inventor: DAWSON ARTHUR TREVOR
Filed: 1901-05-13
Granted: 1902-04-10
Abstract: 9893. Dawson, A. T., and Buckham, G. T. May 13. Mountings.-With the hydraulic recoil apparatus shown in Fig. 1, the recoil causes the piston B' to move rearwards, and the plunger C to be withdrawn from the hollow piston-rod B, the liquid behind the piston passing through the ports b and past the non-return sleeve-valve b<3> to the inside of the piston-rod. During the return movement, the valve b<3> is closed by its spring, and the liquid finds its way back by an inclined groove c and a uniform groove b<2>, which are cut in the upper side of the plunger C. In the modification shown in Fig. 4, the non-return valve consists of a ball b<5> carried in a chamber formed in a piston c<3> screwed to the plunger C, and during the return movement, the liquid passes along the grooves c<4>, b<6>. The invention also includes improvements upon the invention described in Specification No. 10,606, A.D. 1896, according to which the trunnion bearings consist of caps, across each of which a slot is partly formed, so that, when the cap has been rotated so as to bring its slot opposite to a similar slot in the carriage, the trunnion can pass out. The present improvements provide (1) a shroud D', Fig. 7, which, when the cap is in locked position, covers the teeth D<1> on the cap D at all points except opposite the supporting-pin E<2> of the operating-lever E, which lever can accordingly be only inserted and removed when the cap is locked, and (2) a sliding spring catch having projections g, g<1> to lock the cap to the carriage as soon as the lever E is removed.

Granted: 1902-03-20
Abstract: 13,034. Meintjes, L. S. June 26. Liquid-piston pumps.-Relates to pumps for gritty or corrosive liquids and the like. In order to protect the pump and its piston from the action of such liquids, another non-injurious liquid is interposed between the piston and the liquid pumped. In the case of a horizontal pump, the ends of the pump cylinder a communicate with the valve chamber through vertical U-pipes b, c, the upper parts of which contain the non-injurious liquid. Each limb of the U-pipes has a capacity not less than the displacement effected by a single stroke of the pump piston. Float air-discharge valves are provided at k, and gauge glasses at l. In the case of a vertical pump, the liquid piston floats on the surface of the liquid pumped, below the pump piston. A diaphragm, having a specific gravity intermediate between those of the two liquids, may be interposed.

Patent GB-190216950-A (GB)
Title: An Improved Automatic Stop-motion or Feed Regulator for Ensuring the Delivery of Uniform Lengths of Wire particularly applicable to Wire Coiling and Weaving Machines and the like.
Inventor: CHORLTON ISAAC
Filed: 1902-07-31
Granted: 1903-06-18
Abstract: 16,950. Chorlton, I., and Lloyd, C. S. July 31 Wire; bending; shearing.-Relates to an automatic stop-motion for wire coiling or weaving machines or the like, especially machines for making mattresses. A travelling half - nut, normally operated by a uniformly-rotating screwed spindle, engages at a definite position under a lever catch which then releases the clutch mechanism and stops the machine. In the form shown, the screwed spindle a is connected by chain gearing with the main shaft of the machine, and the half-nut g is mounted to slide on a rod h pivoted at one end h<1>. When the clutch mechanism of the machine is thrown into gear, a pivoted link i, connected by a rod k to the clutch-operating lever, engages with a cam surface h<2> formed on the rod h, and forces the half-nut g into engagement with the screwed spindle a. The clutch lever is retained in the operating position by a pivoted catch lever l, until the travelling half-nut g raises it, and thereby allows the clutch lever to be forced by springs into the inoperative position. The simultaneous removal of the link i from the cam surface h<2> enables a spring j, or a weighted cord to raise the rod hand half-nut g from the screwed spindle a. The halfnut is returned to its starting-point by a spiral spring m. The wire coil is then cut, and the clutch is again thrown into gear. The length of the coil produced is varied by adjusting the collar o on the rod h. When stopping the machine, the driven part of the clutch is preferably brought into contact with a brake block, the adjoining surfaces being provided with leather strips.

Title: Improvements in Automatic Coin Freed Stamping Machines.
Inventor: KRIEGER CARL HUGO
Filed: 1902-09-24
Granted: 1903-12-24
Abstract: 20,845. Krieger, O. H. Sept. 24. Stamping and embossing.-Relates to coin-freed machines for producing labels, in which the letters, figures, or characters are embossed in succession on a ribbon or strip h of aluminium or other metal by means of a pair of die-carrying discs d<1>, d<2> geared together to turn equally with a composing-handle d reading an index-plate c. The lower die-carrying disc being in a mount on guide-pillars d<5> is raised against its fellow by means of toggle-levers d<3> which also operate the feeding-mechanism l for the strip, and a slide to correct the position of the dies at the moment of stamping. The togglelever shaft f is coupled to an external handle l, Fig. 5, by the prepayment mechanism, and when the composing-handle is turned to the cutting-off position, a lever g<11> is fastened to the operating- shaft so that a coupled lever g<12> works a cutter g<2> to sever the strip. This action is brought about bv the mechanism shown in Figs. 8 and 9. A lug d<9> on the lower die-carrying disc d' presses down a spring g<7> against a lever g<9> which shifts a clutch g<10> to the lever g<11>, the wedge head g<8> of the spring- simultaneously disengaging the toggle-lever d<3> from the die-carrying disc. In a modification, the toggle-joint is divided by the engaging movement of the clutch. A push-rod b<2> and lever b<3> operated after putting a coin on a sliding tray b shifts a bevelled slide b<4>, which in turn, shifts the clutch b<1> to connect the toggle-lever shaft f with the actuating-handle e. The slide b<4> also thrusts back a weight g which hangs on the coupling-bar g<1> of the cutting-mechanism, and becomes locked by a spring detent b<5> which is thus set free till, after the cutting action, the weight reloads the detent and so disengages it to let the slide be returned by a spring. All the operations are thus performed by operating one handle. A device is provided which allows only a predetermined length of the ribbon to be fed for each coin.
Patent GB-190225328-A (GB)
Title: Improvements in Elastic Fluid Compressors.
Inventor: BROTHERHOOD STANLEY
Filed: 1902-11-18
Granted: 1903-10-08
Abstract: 25,328. Brotherhood, S., and Bryant, C. W. Nov. 18. Compressing.- In an elastic-fluid compressor to be driven by an electric motor or otherwise, the fluid is compressed in stages in two or more pump cylinders b, b<1>, fitted with trunk pistons a, a<1>, which are connected by a common crosshead d and connecting-rod f to a crank shaft g. The fluid is compressed one stage in-theupper part of the larger cylinder b, a second stage in the annular space o surrounding the trunk of the piston a, as third stage in the upper part of the cylinder b<1>, and a fourth stage in the annular space r surrounding the rod of the piston a'. After the successive stages, the fluid is cooled by circulat ng it through coils n<1>, p<1>, q<1>, s<1> placed in a casing b', through which water is circulated by a pump k driven by an eccentric g<1> on the shaft g. This eccentric also drives a lubricating-pump i. The fluid is admitted to the top of the cylinder b by a lift valve l in the piston a. This valve is connected to a rod l<1> passing through the hollow rod c of the piston a, and is held open during the down-stroke by a cam e' fixed to the connecting-rod. It is closed by a spring and by the compressed fluid. The compression is regulated by preventing the valve, l from closing until more or less of the up-stroke has been performed. This is done by adjusting an incline m<2> to engage a roller on a bell crank m, which is pivoted to the piston-rod c and engages the valve-rod l<1>. The incline m<2> is adjusted by means of a screw m<3> operated by hand or by an electromagnet in connection with the starting- switch of the motor. In a modification, a rotarydisc valve is used instead of the lift valve l, and is operated and regulated in a similar manner, the valve-rod being rotated instead of lifted. A helical spring is used both to hold it to its face and to close it. Parts under pressure are provided with relief valves.

Patent GB-190306260-A (GB)
Title: Improvements in and in connection with the Hand Brakes of Railway Vehicles
Inventor: FRAMPTON HENRY SWITHIN
Filed: 1903-03-18
Granted: 1903-06-11
Abstract: 6260. Frampton, H. S. March 18. Brakes.-Relates to either-side brakes for wagons. The hand-lever, when depressed, turns a shaft A on which are keyed two arms D which pull upon a link E. The pull is transmitted to the brake-operating bar G by means of a bent arm F which is pivoted to the bar in such a manner that it cannot turn in a contra-clockwise but only in a clockwise direction. The bar G is thus pulled outwards and applies the brake, its outer end being slotted to slide upon the shaft A. The brakes are locked by means of a pawl carried by pivoted arms S and engaging with teeth on the bar G. To release the brake, the hand-lever is raised and causes the bent arm F to turn and lift the arms S. The brakes are then taken off by a spring. Various arrangements of springs are, in some cases, fitted to the links or arms to aid both in the application and removal of the brakes. To prevent the arms S from jumping up and releasing the brake accidently, they are locked by means of a pin T on them which is pressed down by contact with the upper part of the slot in the end of the bar G. Before the pawl can be disengaged, the arms S must therefore be pressed up with sufficient force to lift the end of the bar G slightly, the width of the slot being such as to allow of this. In a modification, the arms S are raised by a vertical link hung by a roller from the link E, which is bent to serve also as a cam. The length of the link E may be shortened by modifying the shape of the arm F. In another modification, the bar G instead of acting directly on the brakeoperating lever K, acts on an intermediate lever which transmits an increased force to the lever K.

The strip of leather is passed between an intermittenlyrotated feed-wheel C' and an adjustable presser foot D<4> to a rotating disc cutter A<2>, the waste leather D<14> passing beneath, while the bevelled strip D<13> passes above the cutter as shown. The feedwheel is mounted on one end of a lever and is pressed upwards by a spring. The bearings of the cutter shaft A' are carried by a frame A<5>, which, by means of screws D<16>, D<17>, &c. may be adjusted on the frame of the machine to enable the cutter to be set to any suitable angle or bevel required. The frame A<5> carries also a guard A<3> for the cutter, consisting of a conical plate or frame, with a suitable gap or cut away part to allow of the operation of the cutter and presser. The feed-wheel C' is connected by spur gearing with the axle of a friction wheel C<7> surrounded by a friction strap B<1>. One end of the strap is connected by a link B<3> to a lever B, which is pivoted at B<2> to the other end of the strap and is connected below to a rod A<7>, which is reciprocated longitudinally by a cam A<6> on the lower end of the shaft A<1>. Ratchet gearing may be used in place of the friction gearing described.

Title: Improvements in Organs.
Inventor: HOPE-JONES ROBERT
Filed: 1903-04-23
Granted: 1904-03-31
Abstract: 9159. Jones, R. Hope-. April 23. Organs.-The stops and couplers are controlled automatically or in connection with the regular composition pedals, and the drawing on of stops or couplers in one department, as in a manual, is accompanied by a drawing-on of a stop or stops forming a suitable accompaniment in another department, as in the pedal department. The pedal organ is thus provided with a suitable bass for whatever stops are drawn upon the manuals. Fig. 2 shows in section the console of a two-manual organ, Fig. 4 shows diagrammatically the arrangement of the parts when the control is electric or electro-pneumatic, and Fig. 6 shows a pair of associated composition pedals. The set of small motors 68 is provided to draw all the pedal stops or couplers into their off-position, and the set of larger motors 93 to move the desired stops and couplers. into their on-position. A pneumatic or electro-pneumatic valve supplies wind to the off motors, while a set of independent valves is provided to supply wind independently to each of the on motors. The suitable bass rods 15, 25 of the swell and great organs and a third throw-off rod are connected by a pivoted latch board 21 in the manner described in Specification No. 15,461, A.D. 1890. The bass rod 25 carries three insulated collars 28, 29, 30 to close circuits for throwing-off the stops or couplers, for coupling the great and pedal organs, and to throw on the suitable pedal stops, respectively. The fourth collar 31 is used when the swell and great organs are coupled. One of the bass rods only is pushed in at any time The electro-pneumatic valves 51 are similar to those described in Specification No. 15,461, A.D. 1890. The motors 68, 93, 94, 95, 96 are controlled by magnets and bellows. The suitable bass apparatus operates the pedal stop and coupler tablets as well as the stops and couplers, so that the organist may see what stops or combinations have been effected. In a modification, the automatic suitable bass is operated by pneumatic means, valves being lifted by cams, and pressure chambers with check valves being employed. The two pedals shown in Fig. 6, controlling separate stops or compositions forming suitable accompaniments for each other, are adapted to be operated independently or in succession by one movement. Each pedal 226, 236 is connected to its stops and couplers by any well-known means, electric, pneumatic, or electro-pneumatic. The spring of the lower or subsidiary pedal is stronger than that of the upper pedal.
