Granted: 1903-07-16
Abstract: 10,546. Brown, W. M., and Wetmore, E. P. May 8. Electric railways.-Relates to contact boxes for surface contact systems, and consists mainly in constructing the covers of the boxes so that they protect the edges of the body and is that the wearing parts may be readily renewed. The cover is formed of two side portions A, A<1> and the central portions B, B<1>, the portions A, A<1> being of magnetic material, while the portions B, B<1> are of a non-magnetic material which is a good conductor, such as manganese steel. The portions B, B<1> are cast separately, and the portions A, A<1> are then cast round the part B, which has projections band recesses b<1> to connect the parts, a core being used to form the recess for the part B<1>. The part B<1> is secured in its seat by keys c, which are covered in with molten spelter &c., thus enabling it to be removed and renewed when worn. In a modification, the renewable piece is bevelled or dovetailed and driven into its seat after being ground to fit. The edge portions F, E of the box and cover are shaped, as shown in Fig. 2, so that the cover overlies and protects the edges of the box, which project high enough to retain the liquid insulating material for surrounding the circuit-closing devices in the cavity H.

Inventor: MEYER FREDERICK
Filed: 1903-06-04
Granted: 1903-08-06
Abstract: 12,619. Meyer, F., and Batcheler, J. June 4. Exhaust, freeing from grease etc.; condensers.-In apparatus for enabling a supply of hot purified water to be obtained from exhaust steam, two chambers are employed, one to retain the grease, the other to condense the steam. In the first chamber A, steam enters bv the inlet B, and is forced against baffle-plates C, after which it passes by the outlet G to the second chamber H, meeting there a cold water spray K. The steam is thus condensed and collects in the chamber H. An overflow pipe N, and an escape pipe 0, for steam are provided. Manholes M, L are made to allow the apparatus to be cleaned. The grease &c. which collects in the chamber A is drawn off through pipes below. The apparatus may be arranged horizontally, as in Fig. 1, or vertically, as in Fig. 2. There may be one or several baffle-plates, and the division between the two chambers may be vertical or inclined.

Title: Improvements in or relating to Free Wheels and other Gear Wheels of Velocipedes.
Inventor: RILEY VICTOR
Filed: 1903-06-29
Granted: 1903-07-30
Abstract: 14,392. Riley, V. June 29. Clutches.-Free and other gear-wheels for velocipedes are hardened except as to the centres, which are left soft so that they may be readily bored and tapped to suit the ends of driving-wheel hubs or the like. The ring 2 is bored with a small hole and carbonized to a suitable depth, as shown in Fig. 1. The bore of the hole is then increased but still kept smaller than that likely to be required, and the thickness of the ring is reduced to its finished size. The ring is again heated and this time quenched, when the outer parts 4 are hardened, while the part around the hole from which the carbonized metal has been removed remains soft.

Granted: 1903-10-15
Abstract: 16,126. Mellersh, W. r. Jan. 31, [date applied for under Patents Act, A.D. 1901]. Teeth, stopping; teeth, artificial. In order to repair corners and contours of damaged teeth, more particularly those in the front, mineral fillings, composed of a core of porcelain covered with enamel, are fitted to the teeth and cemented in place. The tooth is first prepared by removing the decayed portion and forming a recess to give sufficient hold to the filling. A mould of this recess is then taken in any ordinary way and partially filled with enamel, which is fused. A core of porcelain, shaped as a right-angled triangle with one of its angles very acute and bevelled-to a chisel-edge and having the base tapered to an edge to form the cutting- edge of the tooth, is then placed in the enamel and fused in place. I. is subsequently covered with the enamel body, and the exact contour obtained by further fusion. Grooves are formed in the cavity of the tooth, and projections made on the filling, so that, when cemented in position, a firm attachment is secured. Figs. 2 and 4 show forms of fillings similar to crowns.

Title: Improvement in Portable Vessels for Containing Liquids
Inventor: RAMSBOTTOM HARRY
Filed: 1903-09-24
Granted: 1904-09-01
Abstract: 20,563. Ramsbottom, H., and Richardson, J. M. Sept. 24. Venting jars &c. -Portable cells or vessels for containing liquids are constructed so that any gas generated in them can readily escape, while the liquid cannot flow out if the vessels are overturned. The Figure shows the invention applied to two cells of a galvanic battery. A special compartment 2 is formed at one end, or elsewhere, of the cells, and into this compartment, near the bottom, opens a pipe 6 which, through a pipe 5 and pipes 4, is in communication with each cell above the level of the liquid. Any gases which pass into the chamber 2 escape into the air through a tube 7 having a small orifice at the upper end. Liquid is preveuted from entering this tube by a baffle-plate 9 having an opening at 10 for the passage of gas. A corked opening 8 allows any liquid which may pass into the chamber 2 to be run off. The air passages may be made by sealing U-shaped pieces of celluloid to the cell. A separate compartment 2 may be provided for each cell or vessel.

Patent GB-190325990-A (GB)
Title: Improvements in and pertaining to Electrical Brush-holders.
Filed: 1903-11-27
Granted: 1904-09-29
Abstract: 25,990. Mavor, H. A., and Mavor & Coulson. Nov. 27. Brush-holders, in which a finger presses the brush forward under the action of a spring. A bracket i, consisting of parallel sides 12 and an end-piece 13, is stamped out of sheet metal, such as steel. A nut n serves for clamping this to the brush box f, and for clamping a plate o, say of copper, as shown, flexible leads p carried by this plate ensuring a good electric connection between the box f and the brush a. A finger d, consisting of parallel sides 2 and an end-piece 3, 4, is stamped out of aluminium or steel sheet, and is pivoted at h to the bracket i, suitable slots being formed in each part for this purpose. A spring c is attached to an extension 15 on the piece 13, and to an adjusting-screw k, m carried by a pivot which works in slots in the piece d. The pivot j consists of a central portion 9, Fig. 1, of large diameter, adjacent portions of smaller diameter which fit into the slots in the parts 2, and outer portions 8, 10 of large diameter which fit closely against the parts 2 and so increase their rigidity. The pivot h is formed in a similar way to ensure rigidity at the joint. During the wearing of the brush a, the spring c contracts, and the point of attachment 7 to the finger d is so arranged that its distance from the axis h increases and keeps the pressure of the finger d upon the brush a constant. To obviate slotting the side 1 of the box f, the finger d is made of such a shape that its end 4 can follow the brush a within the box f throughout the entire movement of the brush due to wear. The contactplate o can be removed, without removing the bracket i, by loosening the screw n, and by turning back the finger d or disengaging the spring c, or both. Some of the above improvements may be employed without others.

Title: Improvements in Optical Prisms and Instruments.
Inventor: PUETZ PETER FERDINAND
Filed: 1904-03-08
Granted: 1905-03-08
Abstract: 5727. P³tz, P. F. March 8. Optical prisms.-Relates to prisms, and combinations of prisms, for use in telescopes, and other optical instruments. The elementary prism, out of which the varied combinations are formed, consists of a tetrahedron, Fig. 1, which may be looked upon as derived by the cutting of a cube in such a way as to obtain two of the four faces of the prism coincident with two adjacent ones of the cube, and in the for of right-angled isosceles triangles. These faces, e, f, form the inlet and outlet faces, while the others, c, d, totally reflect the light rays. The useless corners, a, b, may be cut away. Fig. 2 shows a pair of these prisms combined to act as a direct vision erecting- system. Fig. 7 shows a prism system for a binocular telescope each half of which consists of a pair of the prisms shown by Fig. 1. The light which enters the lower face of one half of the system from the objective is ultimately reflected at right-angles across to the second half, by which it is again reflected at right-angles, and into the eyepiece, with the result that the picture, presented to one eye, is produced by the objective opposite the other one. Fig. 8 shows a binocular fieldglass f fitted with the prism combination of Fig. 7. The body of the instrument is formed by tubes o, p, which telescope into one another to obtain an inter-ocular adjustment. A short intermediate tube t engages by an inclined slot u with a pin v carried by the outer tube o, which pin also projects into a slot 32 in the inner tube p. The rotation of the tube t, therefore, results in an alteration in the inter-ocular distance. The focussing-screw 8 acts upon the eyepieces. The prisms are secured in frames attached to the end covers C, D of the tubes o, p respectively.

Title: Improvements in or applicable to Shoe Nailing Machines.
Inventor: BOOTHMAN JONATHAN
Filed: 1904-05-10
Granted: 1905-03-16
Abstract: 10,745. Boothman, J. May 10. Nailing.-Relates to a boot-nailing machine of the type in which a length of wire is severed, and the severed piece, which forms a nail, is moved laterally under a driver by a reciprocating carrierbar, such as that described in Specification No. 24,990, A.D. 1901. According to the present invention, two pivoted levers 8, 8<d>, operated by a cam g, are employed to drive the carrier-bar 7, which is thus subjected to a push in both directions, instead of an alternate push and pull, as previously, when only one lever was used. The lower ends of the levers are provided with setscrews 8<g>, 8<h>, by means of which the terminal positions of the carrier-bar may be accurately adjusted. One end of the carrier-bar is provided with a spring-controlled buffer plate k, which yields when engaged by the set-screw 8<h> and thus prevents any noise. Another feature of the invention consists in the form of the cam m which raises the spring-controlled driver 11<a>. Part of this cam is formed of uniform radius, so that no power is absorbed for compressing the driver spring during the cutting operation, and the final compression of the driver spring is only effected after the completion of the cutting operation.
