Title: Improvement in Micrometers for Measuring Cicular Work
Inventor: COATS ALLAN
Filed: 1903-06-29
Granted: 1904-06-02
Abstract: 14,393. Coats, A. June 29. Calliper gauges. -To measure circular work, whether stationary or in rotation, the gauge is brought up to the work, and a carriage C and cursor M are by it run back along the scale E, until the work touches the flat surface B, the wear disc 0, and the wheel D on the carriage. The surfaces A, B are inclined to one another, at one of two inclinations determined by the stops P, Q, W, the readings for the two positions of the surface B being in thousandths and hundredths of an inch respectively. The diameter of the work measured is more or less than the reading of the micrometer screw R by the reading of the cursor M on the scale E, The thousandths scale of the micrometer screw R is marked on the sleeve S, which can be adjusted for wear. The arm N in being raised or lowered causes the scale E to be moved endwise by the pin and inclined slot F. The inclination of the slot F is determined experimentally and allows for the effect of the variation in the diameters to be measured.

Title: A New or Improved Method and Apparatus for Producing Compressed Air and the like.
Inventor: HEIN ADOLF
Filed: 1903-09-01
Granted: 1904-06-09
Abstract: 18,874. Hein, A. Sept. 1. Compressing.-Air is compressed by means of the impact of an interrupted flow of water or other liquid. In one arrangement, shown in Figs. 1 and 3, water flows from a vessel a through a non-return valve b, a pipe c, a rubber or other expansible tube d enclosed in a chamber q, a pipe e, a stopcock f, a chamber h, a pipe m, and an impact valve n, Fig. 3. The chamber h, Fig. 1, communicates through a non-return valve i with an air vessel g, and a pipe k open at the top to the air in the vessel g is closed at the bottom by a rubber or other expansible bag inside the chamber h. While the water is flowing, the tube d is in a collapsed state, and air can enter the chamber q through a non-return valve t. When the valve n, Fig. 3, closes, the tube d, Fig. 1, is expanded by the impact of the water, and some of the air in the chamber q is forced through a non-return valve r into a reservoir s. The rubber bag l is stated to increase the pressure of the water in the pipe d. In another arrangement, shown in Fig. 4, two flexible diaphragms d<1> are substituted for the flexible tube. They are enclosed in a chamber w communicating through holes x with chambers q, q<1>, which are also in communication with one another. Air enters through a strainer y, a chamber z, and valves t, and leaves by valves r. The water may flow outside the expansible tube or chamber instead of inside. Telescopic or other suitable metal bodies may be used instead of flexible tubes or diaphragms.

Title: Improvements in and relating to Apparatus for Indicating the Stoppage or Reduction of Speed or Utility of Distant Machines.
Inventor: ALLEN PERCY RUSKIN
Filed: 1903-10-20
Granted: 1904-10-06
Abstract: 22,694. Allen, P. R. Oct. 20. Indicating at a distance electrically; indicating interruption of flow of liquids; indicating output of machines; indicating action of pumps.-An apparatus for indicating reduction of speed or efficiency of machines is driven by the machine of which the action is to be indicated, and contains a part or parts capable of radial movement under the action of centrifugal force, and serving to close an electric circuit when the speed is reduced. A switch is also applied to fans or centrifugal pumps, and closes a circuit when the pressure or suction produced thereby falls below a certain limit. A visible or audible indicator, or both, are placed in the circuit. In one form of centrifugal apparatus, a disc a, Fig. 1, has radial holes f, containing balls f<1> which, when the speed is reduced, close a circuit through a pin c, disc a, shaft g, battery, and indicating-device. When the shaft is vertical, the holes f are inclined downwards towards the centre. The balls may be replaced by pistons acted on by spiral springs. In Fig. 5, the ball makes contact between an insulated pin m and tube n, and the disc o of insulating- material is held in a metal cup p. Fig. 7 shows apparatus to be fitted over a shaft g. The disc o is made in halves, bound together by a ring t, also made in two parts which are fastened together by bolts and nuts. The contact tubes m, n are held by an arm s projecting from a ring 3, which is prevented from rotating by a weighted arm 7, 8. A lubricator 6 may be provided, and the ring 3 is made in two pieces. In each case, the apparatus may be connected to the shaft by gearing instead of directly. In Fig. 9, the reduction of speed of a motor 15 causes the closing of a circuit through a battery 18, conductor 17, centrifugal apparatus 11, dynamo frame, annunciator 13, and bell 14. A reduction of pressure in the outlet of the pump 16 independently causes a parallel circuit through a pressure gauge 12 to be closed, one conductor being connected to the frame, the other to a stud in the path of the index hand. In an alternative arrangement, the current is supplied from the leads of the motor through suitable resistances, and a lamp is placed in the circuit of the annunciator and bell. The centrifugal device may be of the type shown in Fig. 5, and be driven by a belt from the motor shaft. The pressure-indicating apparatus may consist of two vertical tubes communicating with each other at the bottom and containing liquid Each tube has a piston, and the piston in the open tube acts by means of a vertical rod on an electric switch, the other tube being connected to the outlet pipe of the pump.

Granted: 1904-05-12
Abstract: 8152. Cox, G. J. April 9. Gas and like engines.- The cooling-water for the jacket of an internal-combustion engine is circulated by convection, and is cooled by air currents induced by the exhaust gases. The refrigerator consists of a vessel D traversed by air tubes a, which are divided into an upper and a lower set. The upper set communicates with a flue E, and the lower set is exposed to a source of cold air. The two sets open into a common box at one end. The hot water from the cylinder jacket enters the casing D at the top by a pipe B, and the cold water flows back to the engine at the bottom by a pipe C. A vent pipe K is inserted at the highest point of the pipe B. Wastage is replaced by water from a small cistern. In a modified arrangement, the upper set of tubes a draws in the air and the lower set of tubes communicate with a horizontal pipe opening into a vertical flue. In another arrangement, the refrigerator D is placed vertically, and air is drawn up through a large central tube, and descends through smaller tubes to a horizontal pipe leading to a flue. The tubes a may be replaced by corrugated metal sheets forming water and air spaces.

Granted: 1905-02-09
Abstract: 9887. Lupton, W., Lupton, J. C., and Lupton, W. J. April 30. Loom temples.- To prevent the bearings of the side roller temples a from being unequally worn, hardened steel balls are introduced into them. As shown in Fig. 1, a ball e may be introduced into the fixed bearing c and then retained therein by a screwed plug or filling f. A steel ball g is similarly introduced in the adjustable bearing d and retained therein by afterwards punching, contracting, or burring in the inner end of the bearing. The latter has a foot part d<1> having slots d<2>, so that, by means of a set-screw h and washer i, the bearing is readily secured to the holder. Both bearings d, c may be made adjustable, if desired, and the bearing d may be made similar to the bearing c. The rollers a, which have their ends cupped or countersunk, are entirely supported by the balls e, g, and are thus kept in accurate alignment. In a modification, the roller end, which is turned down, lies against a ring of balls j, Fig. 4, held by a screwed liner or bush k within a dovetailed opening, so that they do not leave the holder when the roller end is removed. In another modification, the roller end is screwthreaded right and left handed alternately, and is fitted with a flanged bearing-sleeve l, Fig. 5, the balls m lying between this sleeve and an inner recessed part of the bearing. The flanged end of the sleeve is notched or formed with a saw-cut to facilitate screwing and unscrewing. In another modification, the roller end is hollowed out and screw-threaded to receive a flanged stud o, Fig. 6, the flange of which retains the ball p. A spring may be arranged at the bearing not affected by the end thrust of the roller to cause the ball at that end to follow up the roller as the opposite end wears away.

Lifting-jacks and the like.-In connection with lifting-jacks &c. means are provided for giving the load a lateral motion at any desired height in addition to the ordinary lifting motion. Figs. 1 and 2 show a lifting-jack suitable for raising girders, in which the lifting is effected by four racks gearing with pinions working on shafts d, e mounted in suitable bearings on the clutches f which slide or roll on the box framework. The light shaft d transmits the motion through the loose pinions on the stronger shaft e which carries part of the load. The shaft e can be rotated at any height by suitable mechanism or by applying a force to the load, and thus causes the load to move laterally. As modifications, several rollers may be used, while for the shafts d, e may be substituted a single shaft working in a sleeve ; also the working length of the shaft c may be varied by making the turning- mechanism displaceable upon the shaft. Figs. 5 and 6 show the application of the apparatus to appliances for raising heavy vehicle bodies and the like, the shaft e being placed on the supporting- beam m and rotated by gearing. In suitable cases, this gearing may be actuated to give a lateral feed motion to the lifted body.
