Title: Improvements in and relating to Shaft Packing.
IPC: F16J15/34
Filed: 1912-06-20
Granted: 1913-03-27
Abstract: 14,497. British Thomson-Houston Co., [Allgemeine Elektricitõts-Ges.]. June 20. Stuffing-boxes, substitutes for.-In a rubbing- collar packing for a turbine or other rotating shaft, the rubbing parts are held in contact by fluid pressure, the pressure being relieved when the friction exceeds a predetermined amount. The ring d is pressed against a collar b on the rotating shaft by a fluid under pressure admitted behind a diaphragm e, through a passage n and ports l, q, making communication with the high-pressure space p<1>. When the shaft turns, the packing-ring is partly rotated against the action of a spring g confined between a fixed stop i and a stop h on the ring, with the result that the access of fluid to the back of the diaphragm e is throttled through the narrowing of the port l. If the friction is excessive, the port l is carried beyond the port q, and a port r opens to a port m, permitting the fluid behind the diaphragm e to escape by a passage o to the low-pressure space p<2>.

Granted: 1913-02-06
Abstract: 19,149. Washburn, J. M. Aug. 23, 1911, [Convention date]. Range - finders. - An apparatus for use on cameras, or by hand, comprises a sight-bar 1 having a scale of distances at one end and at the other a mirror 8 and a prism 5 with a sighting-line 7 passing down the centre of both.

Title: Improvements in or relating to Acetylen Gas Generators applicable also to other Means for Generating Gas by the Admission of a Liquid to a Chamber in which the Gas is Generated.
Inventor: LEES FRANCIS HENRY
IPC: C10H5/00
Filed: 1912-08-24
Granted: 1913-08-25
Abstract: 19,398. Lees, F. H. Aug. 24. Drip-feed apparatus; liquid supply through prolonged passage.-In apparatus for generating acetylene and other gases, the liquid is supplied in an amount proportional to the demand, through one or more minute conduits between members with co-operating formations of a prolonged or tortuous character arranged so that the turns are effectively isolated from each other. The members may comprise male and female threaded portions, and in this construction the minute conduit is formed by cutting-away the apex of one of the threads. Examples of this construction are shown, that of Fig. 3 being a detached form of water valve for a drip-feed generator. This construction consists of male and female threaded portions a, d, the thread on the part d being cut away at the apex. The liquid passes up through the minute conduit so formed, and away through grooves at the top of the part d, and is delivered to the carbide from a point at the bottom of this cap, or from the rim d'. The liquid may ascend by more than one path by employing a thread with a number of starts. The cap d may be arranged in such a way that it may be screwed up against a resilient washer so as to cut off the flow of water, and it is advantageous to press theparts a, d apart by means of a spring so that the threads are brought into contact and short-circuiting prevented. In the construction shown in Fig. 5. a plug i is screwed into an horizontal tube h, and longitudinal grooves or notches i<1> are provided at the end for the egress of water. The threaded portions may be of large diameter and form the securing-means for the cover of the generator, as shown in Fig. 6. The water in this case passes through the conduit formed by cutting-away the apex of the thread j, and' the rim may act as a stop functioning as the spring in the previous construction, the top of the carbide chamber being notched for the escape of water.

Abstract: 21,184. Dana, H. S. Sept. 17. Pen-extractors; pencil-sharpeners.-Relates to pen-extractors of the type comprising a barrelshaped body and a lever adapted to clamp the nib against the body; and which may be combined with a pencil - sharpener. The body 1, Fig. 1, forms the cylindrical portion of a pencilsharpener 2 and is surrounded by a fixed clamping-band 5 having parallel extensions 6 between which the extractor-lever 9 is pivoted. The body 1 is preferably formed with a hump 14 corresponding in shape with the average pen nib, and the clamping-arm 12 of the lever 9 is set at an angle with the outer arm 9 whereby the greater the effort exerted in extracting the nib, the tighter the nib is gripped between the arm 12 and hump 14.

Abstract: 21,090. Thompson, E. Oct. 16. Reciprocating-punch machines. - Comprises apparatus for perforating paper tape &c., for use in or with automatic telegraph transmitters, and having two alternately-acting electromagnets a, a<1> with their respective plunger rods d, d<1>, strikers e, e<1> pivoted at f, f<1>, and punches h, h<1>. The current supplied to energize the magnet is cut off automatically immediately a hole has been punched, by means of a tongue I moving between two contact screws p, p<1> which are cross-connected to the windings of the magnets, the tongue being moved from one contact to the other by the action of the plungers. The tongue is held against one or other of the contacts by the magnetic attraction of one or other of the pole-pieces q, q<1> of a permanent magnet K; it carries two springs o, o' and is pivoted on a spindle G co-axially with a lever l, l<1> H, of which the arm H has two fingers n, n<1>; the actuation of one of the strikers causes the depression of the corresponding end of the lever and the rocking of the tongue from one contact to the other. Fig. 4 shows an arrangement for operation by a relay. The coil of the magnet a is connected to the relay contact 6 and to the contact p<1>, and that of the magnet a<1> to the contacts 6<1>, p; the tongue I and the relay tongue 5 are in the circuit of a battery M. The tongue and contacts of the relay are shunted by resistances 7, 8, the effect of which is to reduce sparking at the relay contacts and to enable a higher speed of working to be attained. A current is constantly flowing through that shunt and magnet which is at the time being connected to the tongue I, so that the magnet in question is partly energized in advance of the main current. An arrangement for working by a signalling-key is also described. The tape is drawn through the apparatus by rollers s, s<1>; the roller s is driven from a constantly rotating shaft r by a spring coupling, so that temporary checks of the tape due to the action of the punches will check the roller also. The perforations are produced in two rows, and one punch is disposed slightly in front of the other, so that at normal speeds the holes in the two rows are opposite to one another. Instead of the permanent magnet, a roller and spring arrangement may be used to ensure that the tongue is being thrown over to the full extent, and the spindle G may be provided with a brake in the form of a friction clamp.
