Title: Improvements in Apparatus for Pilgering Tubes or Bars of Cross Section other than Circular.
Inventor: REIMAN JAQUES
Filed: 1902-07-12
Granted: 1903-07-11
Abstract: 15,590. Reiman, J. July 12. Rolling.-A pilgering mill for acting on tubes or bars of non-circular cross-section is provided with means to determine accurately the angular movement i m - parted to the mandrel and blank during each forward or idle stroke by the usual arrangement of screwed spindle and nut. The mandrel rod f has a squared portion g<1> (when rolling square sections), which engages a corresponding recess in a head l to ensure the correct feeding of the work between the rolls a. The head slides in grooves on the usual carriage m, but its movement in either direction can be arrested by pawls o, o<1> on each side of the bead engaging racks n, n<1> on the carriage with oppositely-facing teeth. When the rolls commence to act on the work, the squared portion is in the head, the pawl o is in engagement with its rack, and the pawl o<1> is disengaged by a rod p<1>, similar to the rod p, with which a flange h on the rod is in contact. During the rolling operation, the rod is moved back, the head remaining stationary till a flange h<1> on the rod disengages the pawl o and allows the pawl o<1> to engage. The held then moves with the rod, compressing the usual springs r and also a spring t by which clutch members f are engaged to connect the rod to the usual screwed spindle s. On the forward or idle stoke, the rod and spindle are rotated a quarter revolution, the squared portion g<1> then entering the head to stop further rotation, the clutch f<1> being disengaged. The flange h resets the pawls so that the head l may again move forward. The shape of the portion g<1> is determined by the angle through which the rod f has to be turned. A fixed guide may be used instead of the head l, if the feed is suitably regulated, or two flat springs or elastic jaws may be used.

Patent GB-190301063-A (GB)
Title: Improvements in Electric Power-transmitting Mechanism.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-01-15
Granted: 1904-01-15
Abstract: 1063. Carolan, E. A., [General Electric Co.]. Jan. 15. Motor road vehicles.-Relates to electric mechanism for transmitting power from a prime mover, such as a gas engine or electric motor, to a driven object, such as an automobile. The transmitting-mechanism includes a generator element and a motor element, the speed or torque being controlled by controlling the generator or motor. The electrical energy developed in the generator element is supplied to the motor element, which assists the main driving-mechanism. In the generator, both the armature and the field magnets are adapted to rotate, the armature being driven by the prime mover and the object being driven by the field magnets, the speed depending upon the relative speeds of the two parts. Figs. 1 and 2 show one arrangement. The prime mover 1, which may be driven at a constant speed, drives the shaft on which is mounted the armature 2 of the generator. The field magnets 3 are carried by a casing loosely mounted on the shaft and fitted with gearing such as a chain 4, for driving the object. The speed of the driven object depends upon the relative movement of the armature and field magnets. This speed is controlled by the motor, the armature of which is mounted on the main shaft, the field magnets being fixed. The armature and field of the generator are in aeries, and may be closed through a variable resistance to regulate the dynamo, but, as shown in the Figures, the current is preferably supplied to a motor, the armature windings 7 and fields 6 of which are in series; a variable resistance 10 may be in shunt with the field, to regulate the motor and also the reaction of the generator. A switch 12<a>, Fig. 2, is operated by a cam to short-circuit the motor when the rheostat arm 11<a> is in the off position. In a modified arrangement, an alternating-current generator and an induction motor may be employed; the generator field may be excited from a battery &c., or with a commutated portion of the current. The motor may be of the three-phase type, and be regulated by connecting the induced circuits through a variable resistance. In the modified arrangement shown in Figs. 3 and 4, the generator and motor are combined in one structure. The fixed or motor field magnets are carried by a frame 14. The armature windings are fitted in slots 23, 24 in the outer and inner peripheries of a ring 15, which is mounted on the shaft driven by the prime mover ; and the generator field magnets 25 are arranged within the ring and mounted on the shaft, which is geared to the driven object, e.g., by the worm and differential gear shown to an automobile. In another modification, shown in Fig. 6, the two field-magnet structures 43, 44 are independent, but have a common armature 42.

Granted: 1904-04-14
Abstract: 6207. Dexter, T. C. March 14. Feeding sheets.-A machine for conveying sheets of paper from a paper-feeding machine to a printing, folding, ruling, or other machine is provided with means for reducing the speed of the sheets before touching the front guides or gauges. The framework may consist of bars 10, Fig. 1, hinged at 11 to the frame 5 of the paper-feeding machine, and carrying the side brackets 12 for the side-registering mechanism at their other end. They rest on the feed-board 4, having the under-guides 3 extending to the front gauges 2. The sheets are fed from the feeding-machine over the roller 6 on to tapes 18, which run on the rollers 6, 17, the latter of which are adjustably supported through brackets 15 on the bars 10. A second set of tapes 20, Figs. 1 and 3, carried on rollers 21, 22 convey the sheet to the mechanism for reducing the speed, which is on the bracket 23, and is driven through the tapes 20, which, in turn, are driven by the roller 22 and a band 30, with tightening-apparatus shown, from the roller 6. The roller 22 is supported on a bracket 24, connected to, and adjustable with, the bracket 23 by means of rods 26. A roller 54, Fig. 3, driven by gearing from the roller 21, is given a peripheral speed less than, and preferably about half, the peripheral speed of the roller 21. Supported at the top of brackets 23 is a shaft 41, carrying arms 42, and rocked at specified times by a cam 69, Fig. 1, by means of a rod 65 and arm 60. To the ends of the arms 42, links 43, carrying the light rubber-covered rollers 45, are pivoted, and springs between the arms 42 and the links 43, keep the rollers 45 pressed either against the roller 21 or the roller 54. Normally, the rollers 45 are pressing against the roller 21, and nearly the whole sheet passes between the two, and the front end of the sheet is approaching the front gauges, when the rollers 45 are shifted on to the roller 54, pressing the sheet against it, and reducing the speed of the sheet. The correct position of the roller 54 with reference to the front gauges may be adjusted by pinions 25 gearing with racks 25<1> on the rods 10. To prevent this adjustment interfering with the proper movement of the rollers 45 by the rod 65, the connection between the pivoted block 61 and the rod 65 is made by means of suitable friction material which allows the rod 65 to slide in the block 61 when sufficient power is applied, and the range of motion of the arm 60 is limited by a stop 70 in one direction and by the side frame itself in the other direction. The paper may be finally taken on to the cylinder 1, Fig. 1, of the printing or other machine by receiving-grippers on the cylinders.
