Patent Number	Date	Title	Name	City	Description
187,100,331	Feb. 08, 1871	Machinery fur cutting mitres	Richard George Shute	, England	1872 and '73 ads from A. Ransome & Co. state that they were "sole makers of Shute's Patent Mitreing Machines". By 1878, Shute's Patent Mitreing Machines were being made by F. W. Reynolds & Co.
190,801,585	Apr. 30, 1908	Improvements in Tools for Cutting Discs, or Rings Into Two Rings	William T. Jones	, England	Abstract: A tool for cutting disks or rings into two rings consists of a bar a with sockets b, into which fit roughing-tools d<3>, d<4> and trueing-tools d<1>, d<2>, these tools being secured by double inclined wedges c so that they can be adjusted to or from the centre. For centring the tool, the bar a has an appendage e on which revolves a bush f placed inside the ring, which is held in a chuck.
191,022,260	Apr. 13, 1911	Improvements in Ball Bearings	William T. Jones	, England	Abstract: A cage for spacing balls in ball bearings consists of two side rings B, E with partitions A separating the individual balls. The partitions are formed either wholly on one ring, or alternately on the two rings; they fit into recesses between short projections on the opposite ring, and are provided with pins C which are riveted in holes in the ring E to secure the rings together.
191,203,825	Apr. 04, 1912	Improvements in Travelling Carriages of Horizontal Log Band Sawing Machines	Harry W. Durham	, England	Abstract: In an horizontal-band saw-machine for cutting logs into sleepers, such as that described in Specifications 7159/03 and 23,849/03, the logs are carried by a series of short tables m, m<1> mounted on endless chains l, l<1> passing over chain-wheels k, k<1> rotated from an electric motor through mechanism d, toothed gearing d', adjustable friction gearing f, e, chain gearing g, and toothed gearing i, j. Each of the short tables m, m<1> is provided with a fence n, and the logs, while being sawn, are forced into engagement with dogs p on the fence by weighted pressure rollers q<1>, q<2>, q<3>. The fences n bear on a fixed fence R on the machine bed s, rollers t being preferably fitted between them and between the tables and the bed to prevent friction. Guide bars v, w prevent the log and cut off portion from moving sideways and a curved bar u or roller ensures the logs leaving the dogs after being sawn. If a second cut is desired, the feed is stopped while the log is still held by the last pressure-roller q<3>, the saw is raised clear of the log by the mechanism d acting through toothed gearing, and the feed is reversed for returning the log. When the log is returned, the saw can be adjusted to the required position and a fresh cut taken.
191,117,585	Jul. 25, 1912	Improvements in Bench Vices	William T. Jones	, England	Abstract: Relates to means for adjustably pivoting the movable jaw of vices to the projecting leg carried by the fixed jaw whereby the jaws may be kept parallel, and to means for facilitating the rapid opening of the jaws. In the form shown in Fig. 1, the lower end of the movable jaw 1 is provided with a pin 7 adapted to be engaged along the notches in the plates 6 carried by the fixed jaw 2, while, in a modification, the end of the jaw 1 is notched to engage pins between the plates. To provide for rapid adjustment of the jaws, the vice-box 3 is associated with the movable jaw and carries racked extension 4 passing through an aperture in the fixed jaw 2 and normally held by a pin 8 engaging therewith. The rack 4 may be released for sliding movement by depressing the pedal 9 in the construction shown in Fig. 5, the parallel bar 10 at the same time releasing the movable jaw pivot; or by lifting the vice-box in the form shown in Fig. 7, this movement operating through the rocking levers 10, 11 and link 12 to raise the pin 8 away from the rack.
191,223,264	May. 15, 1913	Improvements Relating to Ball or Roller Bearings	Henry Marles	, England	Abstract: A cage for ball or roller bearings is cast in one or two parts from soft antifriction metal, reinforced by embedded wires or strips of steel, brass, &c., which may previously be tinned.
191,328,711	Aug. 07, 1914	Improved Lathe Carrier	William V. Jones	, England	Abstract: A lathe carrier which has no projecting parts is made in the form of a disk with a flange which encloses the driving- pin C and the clamping-screw E.
191,504,972	Jul. 15, 1915	Improvements in Machines for Repairing Saws.	Harry W. Durham	, England	Abstract: In a machine for repairing saws having a milling-cutter for grooving the blade over a crack or other defect and for shaping a corresponding patching-piece to be subsequently silver-soldered thereto, the cutter spindle is mounted eccentrically in a rotatable support, so as to travel slowly in a circular path in the first operation, and is then fixed to cut the patching-piece, which is carried by a rotary arm. The saw blade D is clamped on a table M, which is vertically adjustable on the feet of the frame by inclined surfaces and is acted on by a milling-cutter A carried by a spindle B, which is mounted in a support K rotatable in the framing L. The cutter spindle is driven by gearing C, F from a hand or power operated pulley G. The rotation of the support is effected by an epicyclic train consisting of pinions Q, R on the pulley engaging respectively a wheel P secured to the framing by a pawl W through spur gear U, T, and a wheel 0 secured to the support. After a curved groove has been cut in the saw, a patching-piece Y is secured by clamps to a lever X pivoted on the shaft of the wheel U, the pawl is released, and the support rotated until it is in proximity with the work, whereupon it is secured to the frame by a screw AA, the position being adjusted by screws BB. In this case, the wheel 0 is a fixture, and the lever X is thus swung on its pivot so that a convex surface is cut on the work.
121,873	Jan. 09, 1919	Improvements in Machines for Automatically Swaging and Side-dressing the Teeth of Wide Band Saws	Felix A. Lambley	, England	Abstract: In a machine for swaging and side-dressing the teeth of band and other saws, the saw is fed intermittingly by a finger 23 carried by a lever 22 and adapted to engage the teeth of the saw, and while the saw is stationary one tooth is swaged to press the metal out laterally on both sides by a rotary tool 6 coacting with a stationary anvil 4, and a previously swaged tooth is side-dressed between a pair of laterally acting tools 48. The saw is clamped by a jaw 24 actuated by a cam on a shaft 28, and both the jaw 24 and the swaging-tools are mounted on a slide 3 which is moved upwards on inclined guides 2 and against the action of a spring 18 to move the tools out of the path of the saw teeth while the saw is being fed. The dressing- tools 48 are carried by arms 47 adapted to rock laterally on pivots 46 mounted on a block 45 pivoted to the machine frame at 44. Conical rollers 42 are carried by arms 41 projecting from a shaft 40. When this shaft is rocked, the rollers 42 rock the arms 47 first on the pivot 44 until they are arrested by a stop on one of the tools 48 engaging the saw tooth to be dressed, and then on the pivots 46 to cause the tools to operate upon the tooth. When the rollers 42 are raised, the arms 47 are pushed back by a spring 51 and are separated by a wedge 52.
185,586	Sep. 14, 1922	Device for Holding and Driving Revolving Drills, Reamers, and the Like	William T. Jones	, England	Abstract: A device for holding and driving drills, reamers, &c. comprises a pin C projecting through a hole in the machine spindle A, and engaging a flat surface on the end of the tool B. A rotatable ring F, provided with a knurled exterior and adapted to take a tommy-bar or spanner, has an eccentric groove G engaging the pin C, which is pressed outwards by a spring D. Rotation of the pin is prevented by a projection L engaging a groove in the spindle. For receiving smaller tools, a semicircular sleeve, having a key fitting a groove M, or alternatively a circular sleeve with a hole to accommodate the pin, may be used, a longer pin being then provided.
