Title: Improved Safety Apparatus for Ironing and like Machines.
Inventor: HUNT FREDERICK
Filed: 1905-01-19
Granted: 1905-04-06
Abstract: 1029. Hunt, F. Jan. 19. Guards.-A finger-guard for ironing-machines consists of a bar supported on the table in front of the ironing-roller by springs and so connected that, when the bar is raised by an article of unusual thickness introduced beneath it, the motion is immediately reversed and the article ejected. The bar C is preferably of the shape shown and is guided at its ends by rods D on which are spiral springs. Lifting the bar C entails the rising of the chains L, which pass round pulleys and are attached by hooks to a lever K connected with the reversing-lever E. The upper end of the lever is connected with the slide F carrying the belt forks f, so that by its means the driving-pulley J<1> is driven from either of the two oppositely rotating belts H, H<1>, the other passing round one of the loose pulleys on the same shaft. A spring f<1> normally holds the belts so that the roller is driven in the forward direction. A treadle g provides the usual means of reversal. When the treadle is not pressed down, the table is moved towards the operator and the strong lower spring holds the bar against the roller, so that collars &c. must pass under the guard on the return movement.

Title: An Improved Method of Cutting Straight, Helicoidal and Conical Gear Teeth and Cutters therefor.
Inventor: BOISARD LOUIS
Filed: 1905-04-25
Granted: 1906-01-25
Abstract: 8739. Boisard, L. April 25. Milling. - A helical or "spiralcoidal" cutter for cutting gear teeth of plain or helical spur or bevel wheels on the intermeshing-generator principle is described, together with the method of operating. A mathematical analysis of the principle.and of the form of the cutter is given. The cutter is characterized by having superposed threads, namely a thread of pitch P<1>, Fig. 9, with sides a b, c e, and a similar thread of pitch P<n> having the same external diameter. The threads have a common central point 0. The lateral surfaces of all threads of pitches intermediate to the pitches P<1>, P<n> intersect on the lines M N, M<1> N<1>; which must be preserved as cutting-edges when the latter are formed on the cutter blank. Fig. 1 shows the development of such a thread, A B C D being the resultant thread for the extreme pitches shown. Instead of having straight sides tangential to the teeth of the wheel to be cut, the cutter may be globular. The method for cutting by means of this cutter is characterized by the combination of the following movements. (a) For cutting straight gears : when the screw is globular, a movement of rotation about its axis, in relation with the rotational movement of the cylinder to be cut, a movement of translation along the generator of the cylinder, and an inclination in relation with the pitch to be obtained ; when the sides of the cutter are straight, a reciprocating movement along its axis, besides the movements already indicated. (b) For cutting bevel-gears : the same movements as for straight gears, and, moreover, a progressive inclination of the cutter between the two extreme pitches taken on the primaries at the large and small diameters of the cone. (c) For cutting helicoidal gears : the same movements as indicated above, and in addition an inclination in the direction which the cutter follows relatively to the axis of the gear, this inclination being equal to the helix determining the helicoidal tooth.
